Specification of Letters Patent.

Patented Mai. 25, 1913.

To all whom it may concern Be it known that we, ADAM ROSENKBANZ, a citizen of the United States, resident'of West View, in the countyof Allegheny and State of Pennsylvania, and JOHN LOUIS LANGNER, a citizen of the United States, resident of Cleveland, county of Cuyahoga, State of Ohio, have invented a new and useful Improvement in WrappingMachin es; and we do hereby declare the following to be a full, clear, and exact description thereof.

Our invention appertains to a machine for wrapping commodities and sealing the folds of the wrapper around the article, and particularly to the wrapping, of loaves of bread.

The object of our invention is to provide a machine which will mechanically and automatically arrange the wrapping material, convey the article into position relative to the wrapping material, wrap and seal the article in the wrapper, and finally discharge the article in the sealed wrapper from the machine.

In the accompanying drawings Figure 1 is a side elevation of our invention. Fig. 2 is a plan view of Fig. 1. Fig. 3 is a sectional plan on lines 111111 of Fig. 1. Fig. 4 is a rear elevation of Fig. 1. Figs. 5,

6, 7, 8, 9, and 10 are enlarged detail views of parts of our invention. Figs. 11, 12, 13, 14: and 15 are enlarged detail views showing operative positions of the parts looking in the direction of Fig. 1. Figs. 16, 17 and 18 are similar views of other parts of our invention, looking in the direction of Fig. 4. Figs. 19, 20, 21,22 and 23 areviews showing the progressive stages of the wrapping operation.

, Reference numerals in the following specification refer to like parts in the drawings, in which a main support 2, havin a superstructure 2, is provided with suita le bearings in which are carried a series of shafts. The shaft 3 carries a pulley 4 and pinion 5, the latter meshing with the gear 6 on the shaft 7 which is provided with mitered gears 8, 8 engaging similar gears 9, 9 on the shafts 10 and 11, thelatter shaft being operativelgeconnected to the shaft 12 by means of the veled gears 13.' The pins 14 '(Fig. 3) are each provided with a series of arms. The arms 15 extend through slots in the plate 16 of the main support'2, (Figs. 1-2) and are provided with suitable yokes and operated by the links 16 and cams 16". These arms carry at their'upper ends the top folders 17 which in open relation have an intervening space 18 between them.

Horizontally arranged on each side of the top folders are side folders 17 carried on the arms 17 and operated by the links 18 and the cams 18*, (Figs. 1-3) and secured to the lugs 20 and having a vertical movement are the links 20 having thereon the heads 21, 21 to each of which heads the end folders 22, 22 (Figs. 416) are flexibly connected, the links 20 being operativel engaged to the forked arms 23, 23 whic are operated by the cams 24, 24:. Adjacent to the end folders 22 and for the purpose of heating said end folders are heating ets 25, and carried by the heads 21 are paste depositors 26.

Positioned on opposite sides of the space 18 and below said top folders are the small buffers 19 which are suitably connected to the levers 19' fulcrumed at 19 and operated by the cams 19 and springs 19. Brackets'a carry a spindle b on which is a roll of paper 0', the free end of which is ex-' tended between the rollers d, d which are suitably arranged on the upright e secured framing e, (Figs. 1, 2,7). The. shaft 30 has a mutilated gear 31 adjacent to the sprocket wheel 29 and meshing with a reduced gear 32 on the shaft 33, on the opposite end of which is an intermediate gear 34 meshing with a gear 35 on the shaft 36 of the roller d (Figs. 17). A sector 37 is secured upon the shaft 30 and engages a gear 38 on the shaft 39 which is provided with a suitable member 40 having radially projecting ends in which are suitably secured tongues preferably of flexible material and which are adapted tocirculate within a glue or mucilage container 41 by the operation bf the shaft 39.

On each side of the plate 16 slotted stand ards 42 are secured, and a cutter 13 (Figs. 14) adapted to be moved to and from a cutter bar 44 is supported upon the compression springs 45 which are held in position by the straps 46, the ends of which are connected at 46' to the sides of the cutter protruding through the slots in the standards, and a push-bar 47 is. pivotally connected at 47 to the strap 4-6 and supported freely on the pin 18 on the end of the hanger 49 (Figs. 13) which is suitably suspended from theplate 16, the'other end of said push-bar being provided with a roller 50 which rides against the periphery of the cam 51 (Fig. 3). for 'the purpose of operating the cutter by the action of said cam.

A movable frame 52 (Figs. 1, 8, 9,10) formed of a series of upper and lower parts being separated by'the transverse strips 54:

to forma clearance or passage 55 in which the strips 53 serve as guides for paper delivered into said passage, is slidably mounted on ways 56 suitably secured on the sides of the superstructure '2, so that said frame may be moved to and fromthe rolls d, cl. Arms 57. are carried upon the'pins 14 (Figs. 1, 3) the upper ends of said arms being provided with suitable slots which-engage the studs 58 which are suitably connected to the frame 52, the said-arms being opera-' -tive1y controlled in one direction by the cam 61, connecting rod 59, and link 60 and ,the, return movement being effected by the spring 61 (Figs. 1, 3). A small grip lever 62 having forked end 62' and fulcrumed at 63 on the standard 64 which is suitably secured to the plate 16, is connected by the link 65 to the cam 66 by which said lever is maintained. with its downwardly inclined ends 65 raised above the top of the small stand 67(Figs. 1, 11) against the tension of coil spring 68 which is suitably secured to the plate 16 and to said levers 62 to draw the ends 65 down upon the top of the stand 67 when the action of the cam 66 is withdrawn from the lever. A chute 69 (Figs. 1, 2) formed of the sides 69 is elevated and supported at one end thereof by the support 70, the other end of the chute declinesto and is suitably supported in connection with the shaft 71 which is provided with a crank 72 to which is secured one end of the link 71.

- the other end of said link being attached to the crank 72 on the shaft 7 to operate the star wheels 72 which are carried on the shaft 71 within the chute, the bed portion 73 of the chute extending between the-star wheels vand being carried over the shaft 71, its lower end falling in perpendicular alinement with one side of the space 18 and opposite to the lower extremity of the part 73 a guard 74 is arranged, its'lower end terminating parallel with the lower end of the part 73 and on each side of the part 73 and guard 74 are side-guards 75 which are suitably secured to the parts 69, the lower ends of the guards coiiperating to form a rectangular end to the chute through which the articles are supplied to the space inclosed by the wrapping mechanism, the lower confines of -which form part of theplate 16 and consist of two downwardly swinging doors 76 suitably hung at 76 to the underside of the plate 16, and links 77 operatively secured to the underside of saidkdoors and to the cams 78 (Fig. 3) by which the doors are operated to permit the passage of articles from the space 18 after the .operation of wrapping has been completed and from where the package descends by gravity onto an endless carrier 79 carried on the drums 80 suitably mounted on the brackets 81 on the main support, and'operated by the pulleys 82, 83, andbelt 84.

With the parts of our inventionconstructed and assembled as shown and described .andwith the mechanism in the' positions shown in Fig. 1, the wra ping material on a the feeder roll having its ree end started between the rolls, and the articles to be wrapped furnished to the chute, the opera tion of our machine is as follows: Motion is imparted to the pulley 4 by anysuitable means, thus operating the shaft 3 and pinion 5, the latter operating the gear 6 andshaft 7, thereby actuating the mitered gears 88 and 9, 9 and transmitting a continuous movement to the shafts 10, 11, 12 andto the several cams carried b said shaft. The sprocket Wheel 27, on the shaft 12, the chain 28 and corresponding sprocket wheel 29 be ing thereby driven and operating the mutilated gear 31 and reduced gear 32 by which the shaft 33 and gear 34 are operated to actuate the feed roller d by engagement with the gear 35, the roller will then feed the paperinto the adjacent end of the movable slide during one revolution of the roller when the free end of the paper will be beyond the opposite end of the frame 52, then the mutilated gear 31 will pass out of engagement with the gear 32 at a moment when the cam 61 is timed to act against the roller 61 and force the push-bar to operate then makes a deposlt upon the paper in the frame 52 through a transverse o ening at 52 in the frame which exposes the under- Ill side of the paper to the action ofthe paster until one of the radial ends has been brushed against the same to deposit paste thereon, immediately following which the cam 51 acts against the roller 50 to draw the cutter 43 down and sever the paper against the cutter-bar 44, and upon the completion of the downward movement of the cutter the continued movement of the cam 51 immediately withdrawing its action from the roller 50 and permitting the springs 45 to return the cutter to its higher position within the standards. The cam 61 is then turning from against the roller 61 by reason of which movement the spring 61 is free to reverse the arms 57 and return the sliding frame back to the feed rollers, the severed sheet of paper being retained in position over the space between the folders by the grip lever 62 to receive a loaf from the chute 69 which is directly above said space and into which the loaves are .fed singly by the movement of the star wheel 72 which movementis effected by the link 71 on the crank 72 actuated by the shaft 7, and forcing the pawl 71, carried on the crank 72*, against the ratchet wheel 71 the latter actuating the shaft 71 to thereby turn the star wheel until the carrying member thereof will have turned so as to perimt the loaf to gravitate from the wheel and the hopper, and by reason of the radial stroke of the crank 72 being greater than that of the crank 72 the movement of the former is oscillatory and the pawl 71 is carried back to reengage the ratchet-wheel 71 preparatory to each subsequent operation thereof. The loaf B descends through the hopper, alights upon the wrapper A which having one end free settles down between the folders with the loaf and assumes the folds C shown in Figs. 13, 19. The cam 66 is turned to then operate the gri lever 62 to release the end of thepaper hel thereby, during which operation the cam 19 is releasing the lever 19' sufiiciently to permit the springs 19 to move the buffers 19 to compress the wrapper snugly against each side of the loaf (Fig. 13) while the cams 16 simultaneously close the arms 15 to operate the top folders 17 Fig. 14 which are thereby carried against the wrapper to form the folds D and seal the same across the upper side of the loaf (Fig. 20) following which the cams '18 operate the arms 17 h to pass the side folders 17 against the projecting sides of the wrapper and compress and partly fold the same against each end of the loaf (Fig. 15)' with the effect of formlng the folds E shown in Figs. 16, 21, and then instantly withdraw said side folders, whereupon the upper links 20 to which are attached the small paste depositors 26 are operated by the movement of the cams 24, to bring the end folders 22 down upon the protruding ends of the wrapper to thoroughly form and compress the folds G and to deposit paste on the lower projecting end of the wrapper, as shown in Fig. 17, so that the wrapper is then as shown in Fig. 22. When the return movement of the upper links is commenced, the cams 24: operate the lower links 20 to swing the lower end folder 22 against the projecting and pasted ends of the wrapper to form the folds H and close and seal the same upon the package, (Figs. 18, 23) completing the folding operation. The cams 19 are timed to then operate the lever 19 to withdraw the buffers 19 from the package in the recess, whereupon the cams 78 carry back the links 77 to open the doors 76 leaving the package to descend by gravity from the recess to the carrier 7 9 by which it may be conveyed to any desirable point and discharged. r

If a paraflined wrapper is used, the use of a paste depositor may not be necessary, and the heating of the end folder, as shown, may be relied upon'to heat the paper sutficiently during its contact therewith to cause the end folds to adhere together.

Modifications and changes may be made both in the construction and operation of the various parts of the machine herein shown and described, without departing from the spirit of the invention.
