Y., A FIRM COMPOSED 01* DAVID HEFTER- AND RAY HEFTER MACHINE FOR LINING PAPER-BOX BLANKS Application filed September 10, 1927. Serial No. 218,622.

This invention relates to machines for liningcover blanks in general and more particularly cover blanks for paper boxes, such as, for instance, pencil cases made of cardboard, the covers of which arelined on the inside thereof.

Heretofore, this lining operation was generally performed in the following manner: A machine having a roll of paper mounted thereon was utilized for this purpose. The roll. was drawn along by hand through gluing rolls and then placed over the cover blank where it was severed from the paper roll to form the lining for the said blank. This, as will be seen, was a slow operation, as

i the speed of the machine depended upon how rapidly the operator could draw the paper therethrough and aline it with the cover. It also necessitated the using of a roll of paper of a width sufficient to overlie the entire surface of the cover. The said lining paper, as a rule, has a glossy surface which in practice, makes it diflicult for gluing the pencil box thereto.

One of the objects of this invention is to providea machine wherein the lining mate.- rial, which may be of paper, cloth, leather, or the like, may be automatically drawn off a roll and thus hasten the operation of the machine.

Another object of the invention is to provide a plurality of rolls of such lining material to line the paper boxes in such a manner as to partially expose the cardboard surface of the cover itself, to provide a proper gluing surface of the pencil box.

A further object of the invention is to provide a machine of this nature having a hopper to contain cover blanks therein that will be fed simultaneously with the feeding of the lining material to a predetermined point, where the lining material will be severed from the rollers and glued or pasted to the blank.

A still further object of .the invention is to provide a machinewherein the lining material may be out off to a length slightly less than the length ofthe blank, so that thesaid lining material will not. become separated from the blank due to any friction at the ends thereof.

Further objects and novel features of construction of my invention will become more ap arent as the specification proceeds. i

The cover plate shown in Figs. 12 and 13 before the lining material is applied thereto consists of a plurality of card board sections or the like with their lower surface glued or past-ed to anouter covering of any suitable taining lining material 22 and 23. The lin-' I ing material 22 passes over a glue applying roller 24 and around rollers 25, 26 and 27 and thence through gui deways 28 towards the rear or delivery end of the machine. In like manner, the strip oflining material 23 passes over a gluing roller 30 and around similar rollers 25, 26 and 27 mounted in proper alinement with the said roller 30 and through guideways 31.

, At the rear of the machine and in the uprights 18 there is journalled a shaft 33 upon which there is loosely mounted a drive pulley 34. This pulley 34 may be brought into engagement with a clutch 35 slidingly mounted on theshaft .33 and secured thereto for rotation therewith and operated b means of a. starting lever 36, a link 37, a bell crank 38 link 39 and. lever 40 mounted upon a stud 41 in a supporting bracket 42 secured to one ofthe uprights 18 at the rear or delivery end of the machine. Secured to the shaft 33 at the opposite end of the clutch mechanism there is a pinion 43 in mesh with a gear 7 44 secured to a cam shaft 45 journalled in nailed in a bracket 74 bearings 46 and 47 depending from the bedplate 15. Secured to said shaft 45 is a paper or lining material feeding and cut-off cam 48 provided with a cam groove 49 in which operates-a roller 50 mounted upon a lever arm 51 'swingingly mounted upon a'stud 52 journalled in a bracket 53 secured to the underside of the bedplate 15. Secured to the lever 51 is a link 54 at one end thereof, the said link beingsecured at its opposite end to a lever 55 swinginglv mounted. on a rod 56 journalled in brackets 57 secured to the uprights 17f This lever 55 is connected by means of a forked rod 58 to an arm 59 loosely mounted on ashaft 60.and fitting into a forked arm 59 looselv mounted on a shaft 63: and fastto the shaft 60 which passes through arms 61 and 62 secured to the shaft 63 journalled in brackets 64 and 64 secured to a plate 65 supported on members 66 and 67 slidingly mounted on rods 68 and 69-supported in brackets 70 and 71. Secured to the shaft 60 there are aper feeding or gripping arms 72 and 73. A rack 65 is secured to the underside of the plate 65 and is in mesh with a gear 74 secured to a short shaft 74 jour- The cam 48 is provided at its periphery with a cutout 75 which operates a rename mounted on a lever 77 secured to a pin 78 and connected to a link 79 at one end thereof by means of a lever 77 also secured to the pin 78, said link be ing in engagement with a bail 8O swingingly mounted on studs 81 and 82 journalled in uprights 83 and 84 of the bracket 71. A knife 85 is secured through the crossbar 86 of the bail 80. The shaft 45 has also mounted thereon a cam 87 nrovided with a cover blank feeding cam groove 88 in whichv operates a roller89 intermediate the ends of a lever arm 90 swin 'inglv mounted on a stud 91 journalled in a bracket 92 secured to the underside of the bedplate 15. Secured to the free end of-the lever 90 is a link 9.3 connected at its opposite end to a lever arm 94 loosely mounted on the rod 56 and joined by means of a rod 95 to another lever96 loosely mounted on the rod 56. A stud or pin 97 passes through the upper end of the arm 96 and has mounted thereon an arm 98 having an extension 99 which is secured to a slide bar 100 slidingly mounted in a plate 101 hingedly securedas at 102 to a plate 103 supported on a cross bracket 104 which is in turn secured to the bedplate 15 at the rear or delivery end of the machine. The pin or stud 97 has also mounted thereon a rack 105 in mesh with gear 106 loosely mounted on ashaft 107 extending the entire width of the machine. Fast to the gear 106 or integral therewith there is an arm 108-upon which is'mounted a spring pressed pawl 109 in engagement with aratchet wheel 110 secured to the right hand end of the shaft 107 looking from the rear or delivery end of the machine (see Figs. 2 and 4); Secured to the other end of the shaft 107 is a gear 111 in mesh with an idler 112 which is in turn in mesh with a gear 113 secured to a shaft 114 also extending the entire width of the machine. Thisshaft 114 has mounted thereon rollers 115 (seeFigs. and 4) and the said shaft is supported in the ends of a lever'116 swinginglymounted. on a shaft 107, the said lever 116 being provided near the centerthereof-with an arm 117 on which there is rotatably mounted a roller 118 in contact with the periphery of the cam 87 and the said bracket may be swung downwardly by a spring 119 when the cutout 120 on the periphery of the cam 87 comes-in alinement with the roller 118. The shaft 107 is further provided with rollers 121 and 122 near the center thereof. The gear111 is in mesh with a gear 123 mounted on a shaft 124 supported in bearings 125 and. has se- 1 cured thereto at the center thereof a roller 126 in contact with the rollers 121 and and at the extreme right end of the said shaft there is a gear 127 in mesh with an idler 128 which 'in turn is in mesh with a gear129 mounted on ashaft 130'journalled in bear ings 131 and has secured-thereto rollers 133 and 134. A bracket is secured to the bedplate 15 and acts as a support for theplate 101 the said bracket being provided with an opening to receive a shaft or' stud 1 11 upon which there i's se'curd an arm 142 having a spring pressed pawl 143 mounted thereon and in engagement with a ratchet wheel- 144 connected to a sprocket Wheel 1 15. 1 Integral with the arm 142 is a gear 146 which periodi 'ca'lly engages a toothed portion 147 oil a rack bar 1&8 secured to an am .149 mounted on the pin 97; The shaft 7 1 has secured thereto arm 150 upon which is mounted aspring pressed pawl 151 in engagement with a ratchet wheel 152 \vhich has secured thereto sprocket wheel 153; The ratchet 152 and sprocket 153 are both loosely mounted upon thefsaid shaft 74.

The glue is applied to the roller 24 which is mounted upon a shaft 155 journalled in ears 155 of a glue pot 156b'y a econd roller 21 mounted on a shaft 24 and extend into the said glue pot 156 and supported on supporting-bars 157 secured to uprights 16,- 17 and 18. Secured to the shaft 24 is" a sprocket wheel 158. 7 A sprocket chain 159 passes around the' sprocket wheels 145, 153 and 158 and is kept in engagement with the said speecket wheels by an idler 160 mounted on a s tiid 161 jam-nailed in the bracket 74. To the opposite end or the Slittft as there is Se ctiieda sprocket wheel 162 (See Figs. 1 and 1) and to the shafts 163, 164 and 165 upon which are mounted the rollers; 25, 26 and 27,- tl'i e're are secured sprocket wheels 166, 167 and 168 and a sprocket chain 169 passes over these said sprocket wheels t6 drive the said i ollers: The shaft- 24 has also secured teases a 170 iii mesh with a pinion 171 which meshes with a second gear 172 mounted as a shaft 173 carrying the glue ap'plying roller 17% in Contact with the gluing roller 30 mounted on a shatt 175, which shaft is p esided with again 17 6 iii mesh with gear 172.- A like gear 177 on a shaft 155 is in mesh with gear 170 and derives rotary movement tea-street- Up es the plate 101 there is mounted a hop"- per 180, saidhopper comprising side walls 181 and 182scciire'd to brackets 183 and 18 1 which are adjiistably secured to the said plate 101; .Tlie said walls 181 and 182 may also be guided sideways 156i adjustment by means '01- stuns 185 and 186 the saidside plates passing through slots 187 and 188 in a crossbar 189 secured to bracliets 190 and 191 fast tothe plate 101; The said hopper may be filled. with a stack of cover blanks 192whicl1 are fedto the rollers 115,,133 and 13 1, in the following manner: The slide 100 is pulled backsard towards thev delivery end 0 1'? the machine by the arm 98 and the said slide'bar has mounted thereon a plate 193 which abuts the bottom cover blank leased causes the said cover blank to moi e outward- 1y underneath projecting legs 193* projecting ire-in bars 1941-esilieiitly hiounted in guideways 195. Thesaid legs 193* will permit of but a single cover blank to pass therebetween and the top surface'of the plate 101. This space may be adjusted for various thicknesses of cover blanks by a stud 196 passing through projections 197 on the bars 194 and abutting the top surface of the guideways 195, against the tension of the spring 198. Gibs 199 maintain the slide bar 100 in proper alineinent in a slide-way 200 out in the top surface of the plate 101. Should the space between the legs 193 and the top surface of the plate 101 how ever, be insuflicient to permit of the passage of a single cover blank, tapering plates .201 secured to a cross plate 202 secured to the slide bar 100 will raise the said legs 193 and permitthe passage of the said cover blank.-

The stack of cover blanks 192 are heldbe tween the rear surface of the guides and the frontedge of brackets 203 adjustably secured to the side walls 181 and 182 of the hopper 180. Provision is made so that blanks of various widths may be inserted into the hopper; As before stated, the hopper walls are adjustably' mounted by means of the brackets183 and 184 To increase the width of the hopper, screws 205 and 206 which pass through slots 20? and 208'Ina'y' be loos ened and the side walls may be moved outwardly. Likewise a longer plate, similar to the plate 202 may be secured to the slide bar 100 and aplurality of plates 193 may be se cured to the said plate 202 so that they may abut the ends of the said blanks near their eXtreme ends: Topermit of this, I have pro vided grooves 209 iii theto'p surface of the plate 101 (see Fig. 6). The guiding legs 193 may also be adjusted by loosening screws 210 and removing the said legs inwardly or outwardly asthe case may be, and when the said legs are moved to increase the space between them, the tapering or wedge shape plates 201 may then be secured to theplates 202 at points 211 and 212. Likewise, provision is made for the use of wider lining material than that shown. The said means consists of strips 213, 214 and 215 secured to the slide plate 65. These plates 213', 214 and 215 pr'o'ectinto cutouts in the paper guides 28 an 31 and act as guiding means for the said paper guides 28 and 31 when they are moved inwardly o r outwardly as'de'sired. These paper guides are maintained on the plate 65 by means of screws 216 passing through angular projections 217 on the said paper guides 28 and through a slot 216 in theplate 65;

The lining material 22 and 23 is prevented from raising up from its normal position by means of weights 218 suspended from a rod 219 supportedin brackets 220 secured to the supports/ T0 and also by weights 221 and 222 on a shaft 223 journalled in the brackets 641 and 6 1*. This lining material isfu'rther preventedfro'm raisingup'by means of plates I 224 and 225 hingedly suspended from studs 226 in arms 227 hingedly mounted on the shaft 223 (see Figs. 1 and 4). It will be understood in this connection that these weights bear but lightly upon the said lining material, the only gripping of the paper is done by the paper gripping arms 72 and 73.

Theoperation of the machine is as follows The lining material is first threaded around the rollers as described in the first part of the specification and as indicated in Figures 1 and 3 so that same comes in line withthe forward edge of the cut-off knife 85. The hopper is filled with blanks and the starting lever 36 is operated to throw the clutch mechani'sm 35 to drive the machine. Both the lining material 22 and 23 as well as the cover blanks 192 are fed forwardly towards the rollers 115, 133 and 134, the cover blanks starting to feed slightly in advance of the lining material, the roller 115 having meanwhile dropped into a position to permit of the said lining material and cover blanks to enter between the said roller 115 and the upper rollers 13.3 and 134. This dropping of the roller 115 is accomplished by the weight of the bracket 116 orby the spring 119 when the cut-out 120 comes into alinement with roller 118 mounted upon the lever arm 117 of the roller carrying bracket 116. The feeding then ceases temporarily, the rollers 115 and the rollers 133 and 134 being out of engagement. The roller 115 then comes up to grip both the lining material and the cover blank and the blank and lining material are then further fed by the rollers 115 and 133 and 134 until sufficient lining material to nearly cover the entire blank has been fed from the rollers 20 and 21. It will be understood in this connection that the initial feeding of the lining material as well as the blanks only brings the said materials far enough to be gripped by the rollers 115 and 133 which is not the entire length of the blank, consequently additional feedingmeans must be provided to feed suflicient lining material to cover the entire length of the said blanks as these; are fed through the delivery rollers. The further feeding of the lining material during this period is accomplished by the toothed rack portion 147 in engagement with the gear 146, the said rack having been brought in mesh with the said gear 146 by the lever 96. The said rack bar 148 is out of mesh with the gear 146 until the lining material and cover blanks are brought into position to be gripped by the rollers 115 and 133, that is until'the initial feeding of the said elements has ceased to permit the slide to return to normal position, during which time the teeth 147 engage the gear 146 to further feed the lining material through the glue pot by means of the sprocket chains 159, and 169. The lining material is then severed by the knife 85 being drawn down by means of the connections 79, 77 when the roller 76 enters the cut-out portion 75 on the cam 48 by means of a spring 227 exerting a downward pull on the lever 77*. l/Vhen the feeding of the lining material commences, the lining material gripper arms 72 and 7 3 which are normally above the paper, are brought into gripping contact therewith against the surface of the plate by means of the lever 55 drawing upon the connecting rod 58 connected to the member 59 which encircles shaft 60 and car rics the said shaft 60 against setscrew 228 (see Figs. 4 and 9) causing the said gripper ers 126, 121 and 122. These rollers 121 and- 122 will crease the lining material as shown at 230 and 231. Figure 13, and paste the same to the outside layer 232, the rest of the lining material having meanwhile been'pasted or glued to the cover sections233, 234 and 235 by the rollers 115, 133 and 134, Thispermits of an area 236 on the section 234 to be exposed or uncovered so that a pencil boxglued thereto at some 237 may be directly future time. i a v Rotation to the rollers 115, 121, 122, 126, 133 and 134 is derived in the following manner: The cam groove 88 inthe cam 87 operates roller 89 on the lever arm 90 to which is connected a link 93 connected to levers 94 and 96, the said lever 96 having apin 97 upon which the rack 105' is mounted, the said rack being in mesh with a gear 106 which rotates the roller shaft 107 upon which is mounted the gear 111, said gear 111 being in mesh with gear 123 to rotate the roller 126 upon the shaft 124 which is provided at its opposite ios end with gear 127 in mesh with the gear 129 through its intermediate gear 128 to rotate the shaft 139 upon which is mounted rollers 133 and 134, the roller being through gears 111 and 113 which are connected by intermediate 112. The liningmaterial is fed by means of a cam 48' through the cam groove 49, roller 50, link 54 and lever driven arm 55. It will be noted that the lever 55 is mitting of the insertion of largerblanksby gluing end of the machine.

the slots 180 in the sides frames 181 and 182 so that the member 203 may be slid forward or backward therein as the case may be. A slot 94 in the lever 94 provides means for varying the throw of the lever 95 and the feeding of the blanks. Provision is also made for removing the shaft 107 upon which are mounted creasing rollers 121 and 122 so that either wider rollers may be inserted or rollers spaced Wider apart or closer together when desired. may be accomplished by loosening setscrews 107 in the collars 107 The collars may then be moved inwardly, the center section of the shaft 107 which is keyed to the outside section of the said shaft may then be removed and another shaft having the required rollers suitably spaced apart thereon may be inserted and the collars slid in place again and secured thereon.

It will be noted that the weights 218 and 221 are inclined in such a direction so that they will not bind the lining material when the slide is drawn back towards the front or It will also be noted that the plates 224 and 225 may be lifted off the paper at any time desired by swinging them bodily around center 223. The plate 101 is swingingly mounted so that it may be raised any required distance to accomplish the lifting of these plates 224 and 225 or for any other purpose that may be re quired.

From the above it will beseen that I have provided a means for lining cover blanks adapted to be used in connection with pencil boxes, books or the like, in which a plurality of strips of lining material may be automatically fed to be pasted on said cover blanks and then completed and fed through the machine. It will also be seen that the parts are so arranged as to cut off a length of lining material shorter than the length of the blank and that I have greatly increased the output of such a machine by automatically feeding the lining material and the blanks, and that I have provided a surface on the blank to which may readily be glued a pencil box or the like after the said cover blank has been so lined.
