Specification of Letters Patent. I Patnted Feb, 1916, Application filed August-17', 1915,, Serial No.45,997. I

J of the car versely extending trough 4, which isof rectangular shape in cross section and is adapt- .wrapped, In" advance of said trough, the slide is provided with ;a gripper Which'is adapted to grasp, the endsof a plurality of parallel paper strips or'webs F drawn froma common reel fixed table 6, and 'beneath'a tension device D and a guide rail m' m arranged at the end of the table. After clearing the table, webs F extend across the and are #thence engaged by the gripper. Back of trough 4,]carriag 2 is provided with ously the-several webs F after the same have tance sufli'cient to form wrappers ofthe required length.

in said ways by crank handle U, shaft 3 and a, 6( The carriage is' provided with a transedto receive. the sliced material to be i C overa guide rod 5 and carriage-2, so as to bridge trough 4 I a'cutter adapted to sever simultane-.

The cutter is illustratechmore fully in H Figs. 9-11, and consists ofa lower relatively and an upper movable cutter bar D. Lower bar J is provided with a central longitudinal groove and with a pair of flanking grooves containing cushioning tubes 'g. -Upper.bar D is movable in' slotted upright posts 77 of carriage 2 and is provided with .a blade-e adapted to enter central groove of bar J and with a pair of resilient clenching jaws f adapted to be low: ered upon cushions g so as posts p it" is provided with rollers n, whilesprings '1' tend to raise the bar within the post's. I

Bar D is operated in the following man- V to grip the webs F during. the cutt ng. 0138111171011. In order to'guide bar D along nerz-FrOni frame 'A extend upwardly a pair of posts 7 to which arepivoted byshaft b b, a pair of notched cams H, Each cam is adapted to be held in its inactive horizontal position by a conical pin a c housed withina bore of the cam and pressed into a notch of shaft 6 b 'by a spring d d and screw 6 c. From posts p project a, pair'of pins W which are adapted to engage the operative cam edges. During the forward 'rnovement of carriage 2 these pins will swing the cams downward (or into'the position shown in same by blade 6. :"After the pins W have.

swung the cams into a vertical position,

4 5 they will clear the same so that bar D becomes liberated and may be raised bysprings 1', whilev the cams will be arrested by pins 1) and will subsequently be returned to their horizontal position by pins W uponthe next return movement of the carriage.

The gripper that takes the webs along on the forward movement of carriage 2-, comprises essentially a movable jaw X adapted to cooperate with a relatively fixed i jaw 8 formed at the forward edge of carr1age2 and furnished with a cushioning tube It, Jaw X is hinged to jaw -8, at 9 and isinfluencedby a spring j. From jaw Xdepends a tail piece 10, which is adapted to be engaged-,by a tappet K pivoted at 11 to the body of the carriage, and adapted to be swung upby a fixed shaft or abutment k. When the carriage is moved to the left, a

v I head. K of tappet K will by abutment k be raised against tail piece 10, so as to open jaw X (Fig. 12) and cause the same to receive the ends of webs F. The further movement of the carriage to the left will cause head K to clear abutment 70, whereby 3b the tappet will drop, and cause jaw X to be closed by springj so as to grasp the webs. As the carriage is next moved to-the right, the, jaws will drawthe webs along with them, soas to reel ofl the proper 3!} lengths for forming the wrappers, which lengths are determined by the length of the slide race. When the carriage has arrived ator near the end of its race,'cutter bar I) is lowered in manner hereinbefore described 40 to sever from the webs, the lengths of paper,

for forming said wrappers. As has been stated, the carriage must move some dis tance to the left. or toward table 6, after v its jaw X has grasped the end of the'webs I for the purpose of closing the jaw. In or- I ,der 'to support the end of the webs along the gap requiredfor such movement, there is provided a slidable platen m m adapted to move underneath table 6 and to be alternately projected andretracted from'the forward edge thereof by the movement of the carriage. To operate this platen there is provideda rock shaft 12 having arms 7 f hingedly connected to the left end of platen 5 m m.. From arms I extend forwardly a pair of rods 9 g passing through a guide 13 of carriage 2, and carrying nuts or other ad'- jus table abutments 14 at their free ends.

As carriage 2 is about to complete its stroke to the left, it will strike-arms f f and thus cause the latter to move platen m m to the left. In this way the" gap is opened up at' 1 the right edge of table 6;" which'permits the carriage to complete its movement to I the left and grasp the webs. The carriage guide 13 will eventually strike abutments 14 and thusmove platen m m to the right so as to close the gap and support webs F. The ice.cream or other article to be sliced and wrapped is introduced into a hopper T which is provided near its top with'a hinged shelf m upon which the ice cream to be divided is placed in bulk. As this shelf is swung up, the mass will be dropped into a chamber arranged inthe'upper end of the hopper and whichis of a size'to receive the same. Below'such chamber, the hopper is divided into a plurality of compartments or chutes separated from each other by partitions b. Each ofth e's'e partitions is received in corresponding grooves of the hopper wall and is held in position by a set screw u, so that the partitions may be readily removed and reset At the top of each partition is formed a. cutter head. a v

- which is somewhat wider than the partition,

so that the ice cream after being out into blocks will have a clearance and will not be apt to adhere to the sides of the partitions but will freely drop 'down through the chutes. Through the upper chamber of the hopper there is free to move a plunger afwhich on being lowered forces the mass against the knives. Plunger m is operated by crank handle 5, and pinions P, that'encarried by a' slide. 17 which is providedwith guide rollers v moving in'corresponding Ways of frame A. Slide 17 is reciprocated by crank handle V, shaft 18 pinion Q and racks O. A tapering finger R ex tending from slide 17 over a pin 2/ of frame A, is adapted to be projected under a pin 19 extending laterally from jaw X. ,Thus

upon the movement of slide 17 to the right, finger R will by pin 19 tilt jaw X, so as to liberate webs F, from carriage 2. In order to permit the machine to be thoroughly washed it is provided with a drip pan M,-

'having pet cocks a a.

' The'operation is as follows The ice cream or other body to be sliced and wrapped is from shelf m dumped into. hopper T, and then the plunger a is lowered to force said body against cutters a, and cause it. to fall in blocks through the various chutes upon slicing blade t. Carriage 2 after'having by jaw X. grasped the various paper webs during the latter part of itsreturn-stroke, is moved to the right, (Fig. 4:) to thus carry the webs a distance beyond the right edge of table 6: As soon" as the pins W of the carriage come, during this movement, into en- ,gagement with cams H, they will cause cut- -ter bar-'D to descend (Fig. 5) so that the wrappers are cut off the webs; Upon the further movement of the carriage to the .slice.

sating block- 22 may be placed into, trough 4t right, the several wrappers thus formed, and

which will bridge trough 4, will arrive underneath hopper T' (Fig. "6). The slicing blade '6 upon which the ice cream has been supported is now reciprocated to sever a.

slice or slab 20 ofl each block and cause it to drop "by gravity uponthe Wrapper. The

Weight of the slice will thus cause it to drop into the former 4, and to: take the Wrapper 21 alongwith it, sothat in this way the wrapper will be made to infold the bottom as well. as two sides, but not the ends of the If desired a false bottom or compenby means of which the thickness of the cut off slice may be regulated. After the slice has dropped into the former, carriage 2 is movedto'the left, during the beginning of which movement'the upper flap of the wrap- "per will encounter aroller I of firame A by means of which .such flap will be folded over the top of the slice, (Fig. 7). The inwrapped slab'is then lifted out of the car riage and the latter continues its movement to the left (Fi L 8), so. that jaw X will be,

opened ,and wil reengage webs-F, whence the operation is repeated.
