Application June 10, 1954, Serial No. 435,726
3 Claims. (Cl. 222-327) Our invention relates to injectors for forcing compound into bell joint seals between aligned piping.
-Our invention relates more particularly to an injector or gun which is capable of receiving a container of sealingoompound, and by manual manipulation extruding or expelling the compound under pressure into an arcuate or circular area created at the end of a bell joint by clamp members applied thereto. 7 Features of the invention reside in the fact that containers of sealing compound may be placed in the housing of the unit, the bottom cut outby a can opener, and the bottom then used in the container as a plunger for forcing compound out through the discharge nozzle of the gun.
Other features include the provision of an easily removable cap or cover for the unit to permit the introduction of a container of compound, a threaded plunger rod extended through said cover and the novel arrangement of housing and end cover members and fastening therefor.
Other features andadvantages will bemore-apparent from the following description wherein reference is had to theaccompanying drawings, in which Fig. 1 is a side elevational view of an injector or gun embodying the invention;
-1Fig..2 is a sectional view taken on the line "2 2 of Figzflt 1;. 5. 1
Fig. 3 is also a sectional view and is taken on the line 3-3 of Fig. 1; and
Fig. 4 is a sectional view through the unit taken on the line 44 of Fig. 2.
In the embodiment of the invention which we have chosen to illustrate and describe the same, we have provided a unit which may include a housing which is in the form of a cylindrical or tubular member open at both ends, and a pair of caps, holders, or clamping members 12 and 14 adapted to be fastened over the two open ends of the housing, as will be hereinafter described.
The cap 12 located at the front end of the unit may have an end wall 16 with a medial tapped bore 18 extending through a boss 20 on the outside of the cap, the cap also having a cylindrical bore 22 provided by the peripheral flange 24 to receive the front end of the cylindrical housing member 10. A suitable gasket or washer 26 may be provided in the end of the housing.
We provide a discharge nozzle 28 having the screwthreaded end 30 received in the threaded bore 18, and a screw-threaded end 32 adapted to be received in the bore 34 of a suitable opening in one of the clamp members 36 at the bell joint of aligned piping.
Clamps of the type to which we refer and which are filled with a' compound, such as the plastic base compound known as polysulfide elastomer, after connection to pipes, may be of the type shown and described in our co-pending application for patent on improvements in Leak Clamps for Bell Joint Pipe Seals, filed June 10, 1954, Serial No. 435,727. It suflices to say that each of the collar members has a tapped opening to receive the threaded end 32 of the discharge nozzle 28 so that com- 2,822,959 Q Patented Feb. 11,1958
2 pound in the injector may be forcibly introduced into the area confined. by the clamp members. The compound employed readily adheres to all surfaces that it comes into contact with, which is desirable from a sealing standpoint, but makes the compound itself somewhat difficult to handle.
The cap member 12 may be provided with a pair of outwardly extending lug members38 and 40 upon opposite sides of the flange 24. Each of the lug members may have an enlarged opening .42 therethrough to receive a bolt 44 which has a pair of spaced collars 46 adjacent its end, as shown. Each of the bolts 44 is also provided with a threaded portion 48 to receive the wing nut 50. The ends of the bolts 44 may extend through a pair of slots 52 in peripheral lug members 54 extending outwardly from thev wall 56 of the cap 14. The cap 14, which is similar to the cap 12, also has a circular bore 58 to receive the end of cylindrical housing member 10 and an upstanding flange 60 formed. thereon.
The cap 14 has a medial tapped bore 62 to receive a 4 screw-threaded rod 64 provided with a handle 66 at one 64 but permit the same to keep from rotating with the rod 64 while it is rotated when the device is operated.
' In using theinjector .which we have provided, it is preferable to. loosen the wing nuts 50 so that the bolt members 44 may betiltedoutwardly atan angle to removethe cap 14 together with assembly of piston rod and plunger. A containerC which is filled with a plastic compound to be forced between the clamp members of the bell joint is now opened and placed with its. opened end C againstthe washer 26 in thecap v12. A canopener is used to sever the container cover and mouth portion from the container, thus leaving an open end disposed against the gasket 26. .The can opener may nowbe used to cut the bottom C? to separate the same from the con-' tainer C, permitting the 'bottom, however,'to remain in place on the end of the container. In this condition, a compressible ring such as the piston ring 80, split as at 81, may be placed within the container C against the bottom C of the same, directly below the bevelled edge of plunger 68. The cap 14 may now be rigidly fastened on the end of the housing 10, and by rotation of the handle 66 the fiat working surface of the plunger is brought into contact with the detached bottom and the plastic compound is forcibly ejected outwardly through the discharge nozzle 28. The tapered surface or bevelled edge of plunger 68 urges the ring against the side wall of the container, which, as shown in Fig. 4, efiectively prevents the compound from pushing upwardly through the annular space between the detached container bottom and the container side wall.
With this construction it can be seen that as soon as the container is emptied the container may be disposed of, a new container treated by cutting the bottom end off as described, this container placed in the housing 10, and the operator is ready to eject more compound into hell type joints as required.
The gasket 26, which of necessity comes into contact with the compound, may be disposed of after each container has been emptied, the gasket protecting the end wall 16 of the cap against contact with the compound. This element may be shaped from a readily disposable material such as cardboard.
It will thus be seen that the device provides a novel and expeditious manner of handling the aforementioned surface adhering sealing compound. It will be noted that the only elements of the device that actually come into contact with this compound are the disposable gasket 26,
the split ring 80, and the nozzle 28. After a container of the compound has been completely emptied, and the cap 14 and plunger 68 removed, the empty container, the detached bottom thereof and the gasket 26 may be re moved as a whole, leaving the inside of the injector free from the compound. The only element which must be. cleaned before reuse, other than nozzle 28-, is the ring 80. This leaves the interior and the working elements of the device substantially free from the compound, thereby insuring ease of operation and eliminating time wasting cleaning operations formerly required,
While in the embodiment shown and described the de vice has been applied to introduction of compound into bell pipe joints or similar locations, it will be understood that the invention is directed to an injector for general application wherein material in containers is positioned in the housing and then directed therefrom.
From the above and foregoing description it will be apparent to those skilled in the art that changes and modifications may be made. in the exact details shown, and we do not wish, to be limited in any particular; rather what we desire to secure and protect by Letters Patent of the United States is:
1. A device for removing a plastic material from its container comprising a cylindrical housing having an outlet formed in one end wall thereof and a plunger operably mounted in the other end Wall thereof, said other end wall being removably mounted, a gasket covering the inside surface of said one end wall, said gasket being perforated to provide communication through said outlet, said housing being formed to receive the container with the top thereof removed and the open end thereof positioned against said gasket, said plunger being formed with a fiat working surface merging into a bevelled edge, a split ring adapted to be engaged by said bevelled edge of. said plunger, said plunger and said ring being proportioned to fit inside the container side wall when the bottom thereof is separated from the container side wall and said one end wall is secured in place over the container with said working surface of said plunger positioned adjacent the detached bottom, said ring being positioned between the detached container bottom and said plunger, and means for forcing said plunger against the detached container bottom to force the bottom toward said one end of said 4 housing, said bevelled edge forcing said ring against the inside surface of the side wall of the container and over the space between the detached container bottom and the container side wall.
2. The device set forth in claim 1 wherein said plunger is rotatably mounted on a rod screw-threadedly mounted in said other end wall.
