To all 'whomglt may concern.'

Beit known that I, FRANCIS M. CASE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Apparatus for y Forming Tab-Stock, of which the following heating Celluloid strips, one above the other with an amalgamating solution applied to one or more of the meeting surfaces, to suitable heated Vrolls which are adapted to force the strips together and draw ,the same through'the feeding mechanism and at the same time raise the 'temperature of the strips to a point where complete amalgamation between the same is effected, the feeding mechanism and the parts being arranged so that twov wider strips may be amalgamated against the side faces of a relatively narrow main strip so as to form a tab stock comprising a main tab portion of three thicknesses and side plate portionsextending therefrom to form side plate securing portions which are to be applied to the faces of the card.

The invention may be further briefly summarized as consisting in the construction and combination of parts hereinafter set forth in the following description, drawings and claims.

Referring to the drawings, Figure 1 is side elevation of the apparatus; Fig. 2 is a detail view; Fig. 3 is a longitudinal vertical section; Fig. 4 is a side elevation of the feeding and preliminary heating device; Fig. 5 is a detail sectional view showing the connectionwith the heating element; Fig. 6 is a front elevation; Fig. 7 is a rear elevation; Fig. 8 is a top plan view with parts broken away; Fig. 9 is a top plan view of the lower half of the preliminary heating and feeding device; and Fig. 10 is a vertical section of this device taken upon the line corresponding to the line 10-10 of Fig. 9 but through both halves of the preliminary heater and feeder.

In carrying out the invention any preferred form and construction of parts may be employed so long as they possess the necessary characteristics, but have shown k011e arrangement which is effective in o eration, and in such embodiment the ame comprises' side members 1.- and 2 held together by suitable cross frame members secured to the side members in any suitable manner. Each of the side frame members 1 and 2 is provided at the rear with a surfaced edge or face l3 for the reception of the bearlngs as will later appeal". Each frame member is also provided with an opening 4. for a purposeto be described and a vertlcal uideway 5 also for a purpose` to be descri ed. The other features of the frame members will be taken up in connection with the description' of the detail parts.

Secured to one of the frame members', preferably the member 2 is a gear case 6 containing any suitable power transmission gearing, such for example, as aworm wheel 7 and worm 8 indicated in dotted lines in the drawings, the worm wheel being connected to a driving shaft 9 provided with a driving pulley 10 and the former being connected to a counter shaft 11 mounted in bearings 12 secured to the edge faces 3. This shaft is provided with a spur -pinion 13 meshing with a spur ear 14 in -turn mounted upon a roll. gear iving shaft 15 supported in bearings 16 upon the frame. This shaft 15 is lprovided outside of the frame member 1 with a roll driving gear 17 which normally meshes with a roll driving gear 18 of like size mounted upon an upper roll driving shaft 19 supported in bearings 20 secured to the faces 3 of the sideframe members. Mounted in the lower ends of the guideways 5 formed in-the side frame members l and 2 are bearing blocks 21 supported in the 'guideways by suitable screws 21. These blocks support a lower roll driving shaft 22 which extends across between the two frames and carries upon it alower amalgamating roll consisting of an inner sleeve member 23 having end flanges or webs 24 provided with suitable openings 25, as shownv in Fig. 3, for ventilation, Iand a heater coil supporting sleeve 26 having an outwardly extending flange 274 'at each end adapted to be engaged by the outer sleeve 28. Within the chamber between the sleeve 26l and flange 27 is a heating element comprising an insulating sleeve 29, a coil 30 surrounding the'same and an outer insulating sleeve 31. This heating element is rammed Jamaica?.

formed in. this chamber before the outer sleevev 28 is applied. In -order to supply current to the coil 30 a lsuitable collector .structure is provided on each side of the amalgamating roll, and each of these lstructurescom rises an insulator ring 32 and a` metal co ector ring 33, theseparts be ing held together by suitable screws passing into the llange'27. The insulating ring 32 is provided with a suitable insulatmg tubular member 34 passing through an opening in the flange 27 and adapted to permit .the

passage of a lead from the collector rin to the coil 30j Contact. is'made with t ese sponding rings by suitable contact devices, and each o f these devices comprises a fiber or other insulat' block 35 secured to the correaringl block of the amalgamating roll and carryin a metal contact tube 36 preferably roundg and -supporting a carbon brush 37 forcedy against the collector ring.

by a spring 38 'mounted in the tube and engaged at the ends opposite to the carbon c ontact 37 by a contact strip 39 held against the rear end of the insulating block by suitable `screws 40. These contact strips are extended out to any suitable and convenient point and are then provided with suitable binding posts 41 of any preferred structure. There 1s a collector ring and contact device foreach endof the two amalgamating rolls.

In the ca se of the lower roll, however, the contacts arefarranged upon the up y er surface of the bearing blocks 21, as 1s s own 1n Fig. 1.

Slidahly mounted in the guideways 5 of thel side frame members 1 and 2 are upper amalgamating roll bearing blocks 42, which support an upper amalgamating roll driving, shaft 43 carrying a roll similar in all respects to the lower roll and therefore need.-

' l ing no further detail description. In the case of this roll, however, the contacts for 45- pose 4of bringing the binding posts together Springs the current are arranged below the bearing blocks 42, as shown in Fig. 1, for the purat a convenient point. Keyed or otherwise secured to this shaft is an upper roll drivlng gear v44 meshing with the gear 18 mounted Vupon the shaft 19.

It is necessary that-the upper roll should have a tension toward the roller roll, and this'is accomplished' by means of a pair of 45, one arranged vbetween each of the bearing blocks 42 and a thrust block 46 mounted in the guideway 5 and adapted to be adjustablyheld in position by an adjusting screw 47 threaded into a clip 48 extendl I mg over the top of the frame and having, in-

wardly extending projections 49 engaging in suitable recesses 50 in the frame members.

Each of these adjusting screws 47 is held in' I' place by a'check nut 51. In the feeding of the' strips, as will later appear, it is. necesf sary lto open "the rolls, and this mechanism consists of a lever structure having bifurcated portions 52 and 53 both Y-pivoted upon,

a rod 54 extending across the two frame members. The outer ends of these two-arms `52 and 53 are connected by suitable link members..55 each having a bearing portion 56 mounted upon the corresponding-proj ected end of the shaft 43 of the upper amal-Y gamating roll. These bifurcated portions 52 l and 53 unite atthe rear of the machine and are `connected to a link, or bar 57 provided tion to any suitable manually operated device, preferably to a foot lever, not shown. In order to guide the lower end of this link,

.a bracket 59 is secured to the frame and extends out to a point in vertical alinement with the upper pivot of the link 57 and is there provided with a pin 601 extending through a slot 61 arranged in the link. It is obvious from the foregoing description that when the link 57 is pulled down', the upper amalgamating roll will be raised against the tensiony of the springs 45.

The strips of celluloid to be operated upon 'i by the amalgamated rolls are fed by a combined preliminary heating, feeding and treating mechanism, and this mechanism is with an eye 58 at its lower end for connec-Y its upper surface and near each end thereof ,Y

with an upwardly extending web 66 having -a transverse guiding rib 67 adapted for engagement in the corresponding recessof the upper guiding plate 62.I This member is also provided with preferably a cylindrical openmg 68 extending longitudinally through the same and adapted to receive a heating element', and 'since the heating elements of this preliminary heating, feeding and treating mechanism are substantially the same,

the description of one ply to all.

Each heating element comprises a metal sleeve 69 preferably of brass having threaded, or otherwise secured in the end thereof, a head 70 having a central opening 71 which receives an insulating sleeve 72 provided at this point will ap- .with a flange 7 3' engaging on the outside of the head 7 0.' Passing through the sleeve 72 is a screw 74 with the head on the inside of the element and provided on the outsideof the flange 73 with a nut 75. This screw and nut is therefore insulated from the head 70 and 'the tube 69 and forms oneof the contacts for the elements.` Arranged on the inside of the tube 69 against the wall thereof is an insulating sleeve or tube 76 preferably of asbestos, and within this is a heating 4coil 77 arranged about an insulating core 78. One end of this coil is connected under the head of the screw 74 at one end of the element, and the other end of they coil is connected under the' other similar screw at the opposite end so that the current leads into the heating element at one end and at the.

ing element already described. It is also f provided on its upper surface with a pair ofgrooves 83 Awhich are located in alinement with the grooves 79 .and these grooves together form the guideway for the side plates of the tab stock. This upper intermediate heating and guiding member 80 is provided with a rearwardly extending'portion 84 inclined downwardly and outwardly beyond the back of this mechanism and cut away at the center from front to back to form end flanges 85 which are curved out to follow the periphery .of the upper amalgamating roll when the rolls are closed. The upper lface of this extension 84 between the proJections 85 is provided with grooves 86 in alinement with the grooves 79 and 83 and forming a continuation thereof.`

In order to hold the celluloid strips in the groove 86 an upper plate 87, as shown in top plan in Fig. 8, is provided and this plate corresponds in cross section to the cross section of the` flanges 85. The upper intermediate heating and guiding member 80 is secured to a lower intermediate heating and guiding member 88 having its parts ar-f ranged in opposition thereto, as shown in Fig. 10,and the meeting faces are provided with transverse grooves 89, shown in plan in Fig. 9, ,these grooves being less in width than the grooves 79 and 83 and arranged so that the spacing between the grooves is the same in all cases whereby the inner edges of the grooves 89 are in vertical' alinement with the inner edges of the grooves 79 and 83. These grooves 89 are for receiving the intermediate celluloid strips of stock. This lower intermediate heating and member is provided with a heating element 90 similar to the other heating elements. Each-,of the extensions 84 of the intermediate heating and guiding members is provided with alongitudinally disposed recess 91 andthese recesses form an opening for receiving the solution appliance to be described. Theunder face of the lower intermediate heating lvand guiding member is provided with recesses 92 similar to those referred to in connection with the corresponding upper members and these receive the other Celluloid side plate portions of the tab stock and feed them in a similar manner against the intermediate stri'pof Athe tab stock as will later appear. Coperating with this lower intermediate heating and guiding portion is a lower heating and guiding portion 93 provided with a heating element 94 and suitable grooves 95 coperating with the recesses 92.` In order to facilitate. the entry of the strips into the severa-l grooves or openings, the lips thereof may be beveled, as shown at ets 97, 98 and 99 may be arranged on the face of the entire heating, feeding and guiding' element for supporting the stock in placing it in the openings. In order to force all of the strips toward the center so that the corresponding edge of all the three strips of each piece ofstock will be in vertical alinement, I provide the several members at their meeting faces withsuitable recesses 100 for receiving pressure blocks 101 preferably round in configuration with the curved edge tangent to the axis of the slot or recess with which it coperates, and' each of these blocks is forced inward toward the slot, as shown in Fig. 9, by a suitable spring 102 held in place by la screw or plug 103.v There is one of these pressure blocks at substantially the for each slot or recess, and one on each side ofthe slots .which pass'through the exten- 4sions 84 of the intermediate heating and guiding mechanism.

The treating device comprises an upper plate member 104 and a lowerplate memrectangular shaped aperture, as shown at 106 in Fig. 9, for receiving a suitable wick or pad 107 for holding an amalgamating so- 96 in Fig. 10, and suitable extending brack- -center of the several members forming the g v main body portion of the heating mechanism ber.105,l both'being provided with a central I lution. Each pad is fed by suitable open- Y ings 108 extending through the plate and leading to a: feed tube109, there being a feed tube for each plate, the feed tube ofone member extending' out on one side ofthe machine,` and the feed tube for the other' member extending out on the opposite side. These plates at their ends engage suitable supporting strips 110 fastened between the intermediate heating and guiding members and they are yieldngly held against these supporting strips by suitable springs 111 and bolts 112, which' pass through suitable openings in the two plates and through openings in the strips 110, there being-one of the springs 111 above the upper plate and one below the lower plate on the same bolt,

as shown, so that theseV plates are held together against the supports and the wicks or pads are brought yieldingly into engagement with eachother. Solution is supplied to this treating device through suitable tubes 113 connected to a reservoir 114.

In feeding the strips to theA amalgamating rolls, it is necessary to have a stop limit the inward movement of the celluloid strips while they are being arranged ready for amalgamation, and this is taken careof by providing a plate 115 at the rear of the machine and supporting it upon parallel link members 116 and 117, the links 117 atA the rear being secured to a shaft 118 extended out and provided with a crank arm 119 connected by a link 120 with a bracket 121 secured to the link 57. A spring 122 tends to pull this plate to the rear. This plate may be provided with an eXtra strip 123 for filling up the "entire opening between the rolls.

In order to supply current to the several heating elements of the preliminary h eating, feeding and treating mechanism, I secure an insulating block 124, as shown in Fig. 4, to the end face of ythis mechanism and provide this 'block with suitable openings 125 for receiving the nut 75 of the contact screw 74, and these nuts project well through this block, as vshown in Fig. 5, the uppermost contact 75 engaging a leaf contact126- sel l cured to the block and having a metal tongue 127. f This tongue engages a contact strip carried by an insulating contact block128 secured to the machine in any suitable manner near the end of this mechanism and secured to the blocks by a suitable binding screw 129 connected to one of the wires of the electrical circuit. The two contact nuts' 75 of the intermediate elements engage acom mon leaf contact 130 secured to the block 124 and havinga tongue 131 for engagement with a contact 132 held in place by a bolt 133 forming a binding post. The lower element has its contact engaging a leaf contact 134 having a spring tongue 135 engaging the contact strip 136 carried by the block 128 and secured in place by abolt 137 forming abinding post.

The mechanism is utilized in the .following manner: Assuming that current is sup- Y plied to the preliminary heater either by' connecting to the binding posts 129 and 137 so that all of the heating elements are connected in series, or by connecting one line to the binding' posts 129 and 137 and the other line to the binding post 133 when the elements will be connected in multiple, and further assuming that the current is. led

to the binding post 41 so that the heatingA elements in the amal'gamating rolls are supplied with current, and still further assuming that these elements have been subjected to current for a suilicient length of time to heat the parts, the operator shifts the link 57 causing the upper roll to be elevated.

previously heated. The middle strip in passing through the several parts, however, has been moistened, with a solution'` from the pads 107 and by the action of the heat has been softened on its surface, so that Iwhen the amalgamating rolls press the three strips together and act upon the same with their own heat and with pressure amalgamation takes place, and. the;I three strips are-bound together forming a homogeneous tab stock with a solid portion comprising the three strips and 'with lateral extensions which form side plates for engaging the card after the tabs are cut from the stock.
