Filed Feb. 28, 1961, Ser. No. 92,394 16 Claims. ((11. 222-176) This application is a continuation-in-part of my former application Serial No. 845,809, filed October 12, 1959, now abandoned.

The present invention relates generally to a dispenser or an apparatus for dispensing inert material, such a mixed cement and mixed mortar. The present invention is more particularly directed towards a dispenser utilizing a suitable means such as fluid pressure utilizing air or liquid. Excellent results may be obtained for inverting the bag where spring means is used in combination with the fluid pressure for turninginside out a collapsible and disposable container carrying the mixed cement or mixed mortar.

The instant dispenser is adapted to be used to apply mortar used in new masonry construction or tuckpointing or in applying grout to complex surfaces. The dispenser may also be used to extrude plaster, caulking compound, concrete, tar substances, and other inert or semi-fluid materials thus making it a much more universal applicator or dispenser as compared to prior art devices.

Formerly, tuckpointing operations were only manually performed in a slow and expensive operation and it is now possible for the first time to mechanize tuckpointing by means of the instant mortar dispenser. The dispenser is portable and may be readily used since disposable containers are adapted to be mounted within the dispenser as a time saving feature.

It is, therefore, an important object of the present inven tion to provide a dispenser which is capable of dispensing inert materials such as mortar and cement as well as other more fluid materials, under easily regulated pressure, in a controlled manner, attaining a clean weather-resistant sealing joint, characteristic of good tuckpointing workmanship and without soiling adjacent wall areas.

Another object of the present invention is to provide a dispenser having disposable liners or containers.

Yet another very important object of the present invention is to provide a dispenser having a frusto-conical cone cooperable with a collapsible flexible container which cone has a cone angle of not more than 30 to facilitate movement of the material from the container through the frusto-conical cone with a minimum of drag.

A further object of the present invention is to provide a dispenser having spring means to assist in the unloading of the materials from the disposable container.

Still another object of the present invention relates to providing a dispenser adapted to discharge mixed cement, mixed mortar, and other more fluid materials, which dispenser is comprised of a minimum of parts all of which may be economically manufactured and readily assembled and disassembled, as desired.

Other objects and features of the present invention will more fully become evident in view of the following de tailed description taken in conjunction with the accompanying drawings illustrating several embodiments, and in which:

As shown on the drawings:

The reference numeral 9 indicates generally my dispenser or system or apparatus for discharging under pressure inert materials such for illustration as mixed cement or mixed mortar.

The dispenser 9 is provided with a pressure chamber or a housing which is open at its vertically upper end. A disposable cone or cornucopia 11 is carried within the housing 10. The cone of disposable material is insertable as a filler downwardly and apexially through the open end of the housing 10 and is provided with a flanged upper filler edge 11a which is seated on a chamber or housing edge or flange 10a to support the cone in downwardly depending and progressively increased spaced relation to the cylindrical wall of the housing 10.

To assist in the support of the cone 11, a spring structure 12 is engaged about a lower conical end 11b of the cone 11. When the cone 11 is filled with material the spring 12 tends to balance the load to facilitate discharge of the contents of the cone 11 through the dispenser 9.

3 V The spring 12 also operates to center the cone 11 with respect to the cylindrical housing so that the air pressure insertable into the housing may act with the outer surface of the cone 11 to permit the contents of the cone to be emptied.

Mounted on the housing 10 is a conical-like or frustoconical cover or cone 13. A The cover 13 is adapted to rest at its base on its flanged lower end 13a. Internally the cover 13 has a discharge orifice defined by a reduced cone or cover portion 13b. Suitable clamp means is provided for securing the cover 13 to the housing 10 and to the cone 11, as identified at 14. The clamping means, as illustrated, comprises a pair of C-shaped generally

arcuate rings orsegments

14a, 14a which segments bear against the

flanges

10a, 11a and 13a to secure them in sealed relation together.

The clamp 14 has an adjustable nut and bolt'assernbly 14b cooperable with terminal flanges 14c, 140 which flanges are integrally fastened to the arcuate segments 14a, 14a. 3

Also provided on the bands or arcuate segments 14a, 14g is a buckle structure 15 of any suitable type, such as illustrated in F GURES 7 and 8 of the drawings. The buckle structure 15 includes a loop 16 secured to a strap 15a which is riveted at 17, 17 to one of the arcuate segments 14a. The other arcuate segment 14a isprovided with a buckle member 18 as well as a latch or lock 19. The buckle member 18 is pivoted on hinge to enable it to be assembled and disassembled with respect to the loop 16. The loop and the buckle member 18 may be assembled together by hooking the buckle member into the loop 16 and by pivoting the buckle at 20 so thatthe latch 19may also be. pivoted at 19a andengaged on top of the buckle member 18. In order to secure the buckle member 18 to the arcuate band 14a, the buckle member has a flange 18a'which is riveted to the arcuate band 14a at 20a. In summary, after the cone 11 filled with inert material has been inserted into the housing or receptacle 10 and after the cover 13 has been placed ontop of the cone flange 11a, the clamping means 14 may be utilized to secure the members in assembly together. The latch 19 is pivotal at.19a so that it can be moved into and out of overlying relation with'respect to the buckle member 18 to insure against accidental disassembly of the buckle.

member 18 with respect to the loop 16.

The housing 10 is mounted upon a portable cart indicated generally at: 21 in any suitable manner. As shown,

the cart has a pair of generally U-shaped arms 21a andthe housing 10 is provided with a pair of fasteners 22.,v 22,

studs (or stud axles.) and wing nuts for pivotally securing the cart21 to the housing 10. The wing nuts are in threaded assembly with the housing 10- via the studs to facilitate assembly with the housing. The cart 21 is mounted on rollers. 23, 23. as. Well ason;

legs

24, 24. A handle is secured to the cart adjacent to the rollers-23- so that when pressure is applied to it, the legs 24 maybe elevated off the ground and the cart may bev pushed along the ground surface on its rollers 23.

The dispenser 9 also if provided with-a flexible hose 26 secured to the cover portion 13b and a discharge nozzle 27. is secured to. the opposite end of the flexible hose 26, remote from the cover 13.

A striking tool structure 28. is mounted on the nozzle 27 of the. hose 2.6 and is; provided with

brackets

29, 29 which are securedto the; nozzle in axially-spaced relation. A pair of striking;

tools

30, 30 each. comprising an arcuate rodin slidabl'e

assembly withthe'brackets

29, 29. A pair of

springs

31, 31 aresecured to. the tools 30; 30 by means of snap rings 32,, 32 with the; springs being disposed axially between the

brackets

29,, 29. The springs 311thus havea. tendency to urge the tools toward the surface being worked upon. Either one or both of the tools may be used, such. as is shown inFIGURE 1. If it is desired that only one. of the tools 30 be used, the. other of the tools 30 may be t ned 90 relative to the other of the toolsor else oneof the tools may be drawn axially away from the discharge end of the nozzle 27 after pin 33 has been removed from a hole 33a in the rod or tool 30. When this hole 33a in the rod 30 is moved through the bracket 29 from between the

brackets

29,29 to one side of one of the brackets and after the pin 33 has been replaced in the hole 33a, the tool 30 may be maintained in a retracted position. V

' In operation, the cone 11 is filled with material to be extruded and is inserted within the housing 10. After the cover 13 has been assembled witlrthe housingand after theclarnp means have sealed-the cover in assembly with the housing, air pressure may'be admitted into the housing-10 through its air inlet 1% by means of fluid line 34. An airregulator valve 35 mounted on the inlet fluid line 34 tov aid in the control of the air pressure flowing into the housing 10. A conventional type of safety valve and pressure gauge assembly 36 is provided to guard against excessive pressure within the dispenser.

The flexible cone 11 serves to separate the receptacle into two sub-chambers comprising pressure chamber 37 and material chamber 38. As the air, is admitted into the housing 10 it acts against the flexible cone 11 in such a way that the cone 11 is forced vertically upwardly so that the contents of the cone may be discharged out through the flared nozzle 27. As the cone 11 emptied it is progressivelymoved from within the dispenser housing 10 into thecover 13 as is apparent from FIGURES 2 and 3.

' The cone 11 is preferably made from a suitable flexible material such as rubber or a synthetic plastic. The cover 13 may be made from a suitable material although it is preferred that the cover be manufactured from a reinforced material such as is shown in FIGURE 6. The cover 13 in FIGURE 6 includes inner and outer layers of rubber or synthetic material 130 separated from one another by a fabric layer 13d. It will thus be appreciated that the

flanges

11a and 13a of the cone and cover respectively provide seals to permit the cone and cover to be secured in sealed assembly when the clamping means is engaged in assembly with the

flanges

11a and 13a.

Not only do the cone 11 and the cover 13 cooperate together to provide seals at their juncture to prevent entry of air into the material chamber, but inaddition, the cone 11 and the cover 13 have been particularly configurated to facilitate discharge of the materials from the cone 11 through the cover 13 and out through the nozzle 27. The cover 13 is. manually flexible to assist in the movement of its contents should it'be necessary. The cone 11 has a relatively small cone angle so that its periphery will be spaced from the. cylindrical wall of the housing 10 enabling the air pressure tobetter act against it' for displacing the materials contained within the cone 11. The cover 13 preferably has acone angle of not more than 30 to enable mixed mortar and. mixed cement to pass.

" is used to fill in cracks, expansion joints, spaces between.

bricks, intervals around'doors, and windows, contain about 65% to. 75% of sand or similar inert material, and

only as muchwateras is necessary to arrive at a relatively stiff mixture. In order to reduce the drag between this type of material and the cover 13 as it passes through the coverit has been found that the cone angle should be- 30 or less. to satisfactorily extrude this type of material. Furthermore, the cone 11 and the cover 13 are designed without any pockets or sharp angles which might provide areas where the mortar or cement might set. By manufacturing the cone 11 and the cover 13 from flexible non-ferrous materials, themixedl mortar may flow more freely without danger of bonding itself to any parts.

By supporting a portion of the weight of the material within the cone 11,.the spring 12' assists the air pressure in urging all the material directly toward the' discharge orifice of the cover 13 as'the cone 11 is flexed; Since the cone 11 prevents intermixing of the pressurized air and the semi-fluid material, there is no blow-by and a steady, uninterrupted flow of material is assured. Likewise, the disposable cone 11 and the cover 13 eliminate the necessity of cleaning the dispenser after use, since both may be replaced, if desired.

Provided on the cover 13 is a spring Be and a conical spring base 13 as shown in FIGURES 2 and 3. The operator may ascertain when the machine is empty, by observing and/or feeling the cover 13 at its junction with the hose generally on top of the area of the base of the spring 13e.

Shown in FIGURES 914 are two other flared types of

nozzles

39 and 40 which are each adapted to insure equal flow volume throughout its length, and a gradual blend from the initial circular section to the final rectangular section. By using nozzles of these types the resistance to the flow of the inert materials may be kept to a minimum. The nozzles may be made from any suitable materials such as cast aluminum and the like.

A modified dispenser indicated generally by the reference character 9 is illustrated in FIGURES l and 16. The cone 1.3 is similar to the cone 13 only it is comprised of a double layer or thickness of rubber coated nylon indicated at 41. Each layer of rubber coated nylon is identified at 41a, 41a. The nylon material in each layer is indicated at 41b while the rubber coating is indicated at die. The cone may be manufactured by using a length of rubber coated fabric 41 and coiling it and securing the opposite ends to the inner and outer sides of the cone 7 13 by an suitable means such as tape or glue.

Mounted upon the cone 13' is a collar 42. The collar 42 has a radially outwardly turned lower end 43 and the spring 45a is welded to the radially outwardly extending flange portion 43, as indicating at 44.

The hose 26 is telescoped over the upper end portion 13b of the cone. A relatively stiff tubular support sleeve 44a underlies the lapped junction of the cone portion 13b and the hose 26. A clamp 45 is used for the purpose of securely attaching the rubber hose with the upper cone portion 13b. The spring 45a extends above the clamp 45 to support the hose 26 and to aid in the passage of mortar through the juncture between the hose 26 and the cone 13' by preventing the hose from kinking at this juncture.

Mounted upon the collar 41 is a vibrator support flange 46, the flange 46 being welded at 47 with the collar 41. A vibrator indicated at 48 is bolted at 49 to the vibrator support flange 46. The vibrator 48 includes a vibrator housing Stl which has a tubular bore 51. Mounted within the bore is a piston 52 which is adapted to execute a reciprocating movement within the bore 51 in the general direction of the axis of the cone 13.

The vibrator 43 has an upper closure member 53 which is in threaded assembly with the bore 51 of the housing 50, as indicated at 54. It is the closure member 53 that is bolted at 49 to the vibrator support flange 45.

The piston 52 is supported on a spring 55 which is in turn positioned within the bore 51 and supported on a bolt 56. The bolt 55 is in threaded assembly with the bore 51 at the lower end of the housing 50, as indicated at 57. It will be noted in FIGURE 12 that the piston is shown in normal position. Connected with the housing 50 is a fluid line 58 which is in communication with the housing bore 51. When high pressure fluid passes from the compressor 0 to the fluid line 34 to turn the cone 11 inside out some of the fluid is channeled away from the fluid line 34 through the T-shaped connection indicated at 59 into the fluid line 58. It will, therefore, be appreciated that a single compressor may be used to simultaneously turn the cone 11 inside out while operating the vibrator 48.

When air is caused to pass through the fluid line 58 the piston 52 is moved vertically and the spring 55 is compressed. When the piston 52 is moved a suflicient extent the air passing through the fluid line 58 into the bore 51 is vented to atmosphere through the outlet port 60. When the fluid is vented to atmosphere through the outlet port 60, the spring 55 functions to elevate the piston 52 and return it to normal position so that the cycle may again be repeated. The piston or vibrator preferably has a stroke of at least /8 inch to /2 inch and moves through 300 to 2500 cycles per minute.

By manufacturing the cone of a flexible rubberized material, the cone may be more readily cleaned after use. Another advantage of constructing the cone of a rubberized coated material is that this type of cone is relatively flexible and the vibrations do not deteriorate the cone as rapidly. If the cone were manufactured from a metal product the vibrations would cause destructive deterioration of the cone 13'. Yet another advantage of the present cone construction resides in the fact that the cone 13' may be manually worked to cause materials which tend to become lodged at the upper cone end 13!) to continuously flow therethrough. When a dispenser is being used there are times when it is shut down for different lengths of time. When the dispenser is again started, and when the mortar is urged through the hose 26, some of the mortar located at the upper discharge end 13b of the cone may not be as fluid as it was originally. The operator may manually work the upper end of the cone to cause this material to readily pass through the hose 26 due to the flexible construction of the cone. The side wall of the cone has a thickness of approximately 1 of an inch and a material of this thickness may be readily flexed by the hand of the operator.

When the dispenser 9 is to be shut down for a short period of time, the air pressure passing from the compressor c may be shut off from the line 34 by means of quickdisconnect couplings. The fluid flow may also be shut off by operating the pressure reducer valve 35 as shown in FIGURE 1 and FIGURE 12. The fluid flow to the vibrator 48 may be regulated or shut off by operation of the valve 61. It is more desirable to provide shut down valves in close proximity to the vibrator and to the pressure chamber 37 especially where the dispenser 9' is mounted on a scaffolding at a point removed from the compressor. The operator may operate the

valves

35 and 61 while he is on the scaffold without having to shut down the compressor.

The fluid line 58 has a quick coupling 62 which may be attached and detached to the valve 61 without loss of pressure so that the hose 58 may be removed for any desired length of time when the dispenser 9 or 9' is not in use.

Shown in FIGURES 17-22, inclusive are a series of mortar dispensing tools identified at 63, 64, 55 and 66, respectively. Each of these tools has a

tubular shank portion

630, 64a, 65a and 66a, which are adapted to be telescoped within an open end of the hose 25, as is shown in FIGURE 14. Each of the aforesaid tools has a working head indicated at 63b, 64b, 65b and 66b. It will be noted that these working heads are differently shaped to perform different types of tuckpointing or mortar dispensing operations. The head at 6% is relatively flat, the head 64b is relatively circular, the head 65b is relatively angular, and the head 66b is relatively flat and comprises a hawk. In each case the mortar dispensing tool has a fluid outlet 53c, 64c, 65c and 660 disposed centrally of the working head.

As material or mortar is caused to flow through the hose 26, it moves through the tubular end portion of the mortar dispensing tube in all forms. When the material approaches the vicinity of the working head adjacent the discharge orifice, it will be noted the material is caused to flow between spaced working head areas which are disposed on opposite sides of the outlet. Since the working heads of the tools 6365 are all of generally the same type, a description of the working tool 63 will suflice for all of them. The upper end of the tubular shank portion guests 63a is altered from circular form to a rectangular configurationin order thatthe orifice 630 will be rectangular. It will be noted that the tubular portion 63a is flared and renderedrelatively fiat, as indicated at 63d so that the upper end of the tubular portion 63a has a rectangular configuration and merges with the edges of the head 63b. When mortar passes through the tubular portion 63a, its configuration changes from a circular shape to arectangular shape as it is emitted from the discharge opening 630. It is by this construction there is less mortar drag in the line and in the'too'l and" then when the mortar is to be omitted the shape of the stream is changed to aid in the movement of the mortar in grooves between bricks.

The working head 635 has a width which corresponds generally to the width of the discharge orifice 630.- The working head 63!) is flared at 63c so that as the mortar passes from the orifice 63c it may more readily be dispensed from the tools 63 into the crack or surface on which or into which the mortar is to be dispensed.

When the dispenser 9 is to be used for tuckpointing a wall, the orifice 63c and the width of the working head a 63b correspond generally to the joint or interval between the bricks. Thus, when the mortar is emitted from the discharge orifice 630 it may pass directly into the opening between the bricks and the tool may be movedback and forth as the mortar is being dispensed so that the mortar may be worked into position by the work head 63b of thetool. The working head 63b extends on opposite sides of the discharge-orifice so that the tool may be more readily worked back and forth during the discharge of the mortar into the space between the bricks; T he configuration of the working head is adapted to the type of job that is to be done. i I

FIGURES 21' and desirable to accumulate a certain amount of the mortar on top of the working head 66b so that it may be man-- ually dispensed onto the surface to which itis applied. Rather than exposing a large amount of the mortar to the atmosphere at one time, a limited amount of mortar may be accumulated on top of the hawk so that it may be manually applied to the work surface. The hawk 66 shown in FIGURES 2'1 and 22 is provided with a cut-off valve as indicated at 6:7. This cut-01f valve" comprises a relatively flat flange which is adapted to be t'elescoped into the opening 68 of the, tubular portion 66a; This shut-off valve 67 includes, a valve plate or flange 69 whichis held on the hawk 66" by means of support platesv'lt} which are welded to the underside of the hawk. The valve plate 69 may be moved transversely to the tubular portion 66a to permit mortar to pass through the discharged outlet 66c or to cut-.ofi' the flow.

The tools shown in FIGURES 17-20 may be provided with cut-off valves of the type shown at 67' in FIGURES 21 and 22.

In conclusion, it will be appreciated that the instant system or dispenser enables tuckpoiriting' operations to be mechanized and no longer is it necessary to perform tasks of this type manually which in the past has been a slow and expensive operation. The instant apparatus enables the cracks to be filled at a much greater speed with good penetration to considerably greater depths than has been possibte in the past.

It will be understood that modifications and variations may be efiected' without departing from the scope of the novel concepts of the present invention.
