Within the channels of the trackways, there are reciprocatingly mounted slide bars 40 and 41 aving antifrlction rollers 42 disposed within the channel, and.
adapted, as will hereinafter more fully be pointed out, to carry the wrapper and can transference means to vand fro.
The wrappers A are supported upon a ta ble 43 disposed at the upper end of a screw 44 movable through the threaded bore of a worm gear 45, rotatably disposed in the hearing portion 46 of a crosspiece 47, connected at its ends to the supports 30 and 31. A transverse shaft 48 is journaled in brackets 49 and50 formed upon the erosspiece 47 and in bearings 51 and 52 formed in the supports 30 and 31, and having mounted thereon, a worm meshing with the gear 45 and adapted upon being turned to slowly turn the saidgear and thereby gradually and slowly cause the table to be raised as the wrappers are removed therefrom, the successlve upward movements of the table being equal to'the thickness of one wrapper. Upon one end of the shaft 48, there is provided a ratchet gear 53, and at the side of the same, an arm 54 provided with a spring pressed'pawl 54 engaging the ratchet, the endof the arm being connected by a connectin rod 55 to a crank arm 56 provided upon 51c end of a shaft 57 journaled in the supports 30 and 31, and adapted to continuously rotate from the transmission means as will hereinafter more fully appear.
The stack of wrappers is guided and confined at its forward side by means of bars 58 and 59 supported at their upper ends upon a transverse shaft 60 journaled in the supports 30 and 31 and disposed below the upper end of the stack and provided at their lower end with forked portions '61 engaging over the shaft 48. At its rearward side the stack is engaged by bars 62 supported at their upper ends in brackets 63 mounted upon a shaft 64, and fixed against rotation by means of set screws 65, the ends of the said shaft being. adjustably engaged in slots 66 and 67 provided respectively in the extension members 33 and 34. There are also mounted upon the shaft 64, brackets 68, in the c lindrical portions 69 of which there are isposed vertically arranged pressure members '70, the lower end thereof being capped with rubber or other suitable frictional material as at 71, springs 72 disposed between the lower capped ends of the brackets yieldingly engaging the members with means 39 there are mounted standards 76 and 77 having tables 78 and 79 provided thereon and upon which there is supported a transverse platform 80. A similar platform 81 is supported between the tables 35 and 36, and a third and longitudinally disposed platform 82'is supported at its ends upon the tables 35 and 78. Upon the respective platforms 80, 81 and 82, there are mounted paste boxes 83, 84 and 85. The platform 81 is adjustable by means of slots 81 and bolts 81, while the platform 82 is similarly adjustable by slots' 82 and 82 to permit'of the paste boxes being adjusted to different sized wra pers.
T e box 83 comprises side members 86 and 87 havin bearing portions 88 at their forward en s in which are journaled therespective shafts 89 and 90 of a paste feed roller 91, and a rotarypaste transference member consisting of an arm 90 fixed to the shaft 90 and carrying a'flexible brush member 90 of rubber or other suitable material and adapted upon rotation to successively receive paste from the roller 91 and impart the same to the edge of the paper as at a Figure 1. A ar 92 is provided upon the shaft 89 which meshes with and drives a smaller gear 93 provided upon the shaft 90, the shaft 89 extending from the paste box through a supporting bearing bracket 94 mounted upon the table 79, the said shaft being provided at its end with a sprocket 95 driven by a suitable chain connection hereinafter referred to, from the transmission means. The floor 96 of the paste box is in yielding enga ement at its forward end with the surface 0 the roller 91 and may be regulated relatively to the surface of the said roller by means of a plurality of elongated set screws 97 hearing at their forward ends upon pivotally mounted shoes 98 in turn to bear upon and move pins 99 engaging the flexible end of the floor. The flow of paste to the surface of the roller 91 may thereby be accurately regulated both as to thickness and location.
'The paste box 84 is similar in construction to the box 83, the driving shaft 100 carrying the roller 101 and the gear 102 which meshes with and drives the smaller gear 103 upon the shaft 104 carrying the rotatable paste transference member 105 extending through a supporting bearing bracket 106 supported upon the table 36 smaller ar 111 provided upon the shaft 112 of e paste transference member 113,

At the forward ends of the slidebars 40 and 11, there are mounted journal boxes 119 each having a pair of sockets in which are respectively mounted the ends of a non-rotatable shaft 129 and a rotatable shaft 121. Upon the non-rotatable shaft 120 there is mounted a pair of gripping fingers 122 ex tending beneath and adapted to cooperate with a pair of gripping fingers 123 to grip the wrapper 1n the forwardly moved position of the slide bar as indicated in Figures 1 and 5, the said gripping fingers being preferably capped at their ends with rubber or the like. An arm 124 mg a roller 125 is provided upon the shaft 121 and engages at the ends of the forward and rearward movement of the slide bars, the respective tripping cams 126 and 127 to cause the fingers to grip and release the wrapper, the rs being retained in their moved positions by means of leaf springs 128 secured to collars 129 on the non-rotatable shaft 120, and be upon fingers 130 provided upon collars 131 mounted on the roilataglle shaft 121, the spran' gs act' upon t e ers at either side of the de a d center formed by the afls of rotation of the shaft.
In order to position the wrapper to be properly gripped by the fingers, there are provided at each side of the stack of wrap pars upon the hams slideways 132 and 133 angularly disposed and adjustable as to their angle by means of the circumferentially slotted base plates 134 secured to the frame by bolts 135 and 136. In the channels 137 and 138 respectivelyof the slideways there are mounted slide-rods 139 adapted to be reciprocated by crank levers 140 and 141, en ga g pins 142 provided upon the rods at their slotted ends 1413 and 144, the said levers being pivotally mounted at 1 16 and 147 upon posts 148 and 119 formed upon the frame and ha their short arms connected by rods 150 and 151 respectively to levers 152 and 153 pivotally mounted at 154 and 155 upon the frame, springs 156 and 157 bein connected between'the inner arms of the sai levers 152 and 153 and the points 158 and 159 secured to the frame, and normally holding the slide-rods in their retracted positions.
Upon the slide bars 40 and 41 there are secured brackets 160 and 161 pivotally supporting trip fingers 162 and 163, the said finthe path of the inclined ends. of the levers 152 and 153 and held against stops 164 and 165 by means of springs 166 and 167. -During" the rearward movement ofthe slide bars, the trip fingers 162 and 163 carried thereby pivot during their engagement with the levers 152 and 153 and ride freely over the same. When the slide bars move forward however, the trip fingers are held rigid during engagement with thelevers 152 and 153 and gers having inclined ends and projecting in cause the same to be swung about their piv ots thereby reciprocating the slide-rods 139.
The slide-rods 139 are jointed at 168 (Figures 6 and 7) and during their projecting movement first swing downwardl into engagement with the wrapper an continue moving toward each other in engagement with the wrapper, causing the same to be humped at its intermediate portion. For this purpose a projecting arm 169 is provided uponthe forward end of the slideway and engages the under surface of the forward portion of theslide-rods, the said sliderods having at said under surface an inclined surface 170 which causes the same to be raised and lowered. At the forward end of the rods 139 there are provided caps provided with an inset of rubber or other suitable gripping substances 181 provided with a threaded shank 182 engaging the end of the rod to enable adjustment.
When the wrapper is in its humped positiou, a pair of spacing fingers 183 and 181 having wedge shaped ends 185 and fixedly mounted upon the transverse rock shaft 60, enter beneath the wrapper and hold the same raised so that it may be gripped at its edge by the gripping fingers 182 and 183. .As indicated in Figure 5, the shaft is rocked by means of an arm 187 fixed thereon and provided at its end with a roller 188 engaging a cam 189 provided upon the shaft 57.
At the end of the machine opposed tothe stack of wrappers, there is provided an extension frame comprising a pair of tubular standards 190 and 191 havin circular bases 192 and 193 and provided with telescoping posts 191 adapted to be fixed in their position by means of set screws 195. Collars 196 and 197 are secured to the posts 194 and longitudinal rods 198 and 199 are screwed thereon at one end as at 200 and at their other ends are screw threaded at 201 and adjustably engaged with a transverse crosspiece 202 connecting the supports 39 and 31, lock-nuts 203 fixing the position of the said rods. Upon the rods 198-a'nd 199 there are supported, in spaced relation, inverted l3- shaped supports 204 and205. carrying a longitudinal platform 206 disposed beneath and supporting the upper part of a feed belt extending over rollers 208 and 209 mounted.

Reciprocation of the post is. rought about by means of a link 400 connecting its lower end with. an arm 401 provided upon a rock shaft 402 journaled in the supports 343 and 344, the said rock shaft 402 being provided at one end with a lever 403 pivotally connected to the end of a bar 404, the other end of the said bar being provided with a slot 405 engaging a stud shaft 406 provided upon the support 343, rollers 407 and 408 being provided at the ends of the said slot which ride upon acam 409 provided on the shaft, the said shaft being rotated by a gear 410 provided thereon and meshin with a pinion 411 provided on the en of the sprocket shaft 276.
- As the plunger head descends, it forces the can downwardly between the rollers 353 and 354 at the same time folding the lower projecting portion of the wrapper upwardly and pasting the same upon the folded upper and side portions as, indicated in Figure 23. As the can passes from between the rollers, it may drop upon a suitable chute (not shown) to convey the same away from the machine.
M ;1 improvements provide 'a machine whic may be operated with relatively great speed in which cans or other suitable articles may be wrapped in a clean, neat uniform manner. The imparting of'the paste to the wrapper and the handling of the pasted wrapper in connection with the can or other article is such that the workingparts of the machine will not come in contact with the paste and therefore will not impair the efiiciency thereof by becoming gummed with the paste.
