Specification of matters Eatent.

Application filed July 21,1911. serial Ho. 639,?19.

following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification This invention relates to improvements in feed mechanisms for wrapping or other machines designed to feed articles from the lower end of a stack of sgch articles to a wrapping mechanism or other mechanism for further operation thereon. The invention is herein shown as applied to a chewing gum wrapping machine to feeding sticks or cakes of gums from tha lower end; of a stack to a wrapping mechanism or mechanisms by which the wrappers are wrapped about the gums.

' Among the obje'cts'of the invention is to provide a feed mechanism of this general character which may be operated at high speed, and which is so arranged as to mini mize the shock due to the contact of the movable feed element against the articles, and thereby minimize the liability of crushing or deforming the articles being operated upon.

Another object of the invention is to provide an improved mechanism tor alternately -feeding articles from the lower end of a stack or pile thereof to wrapping or other mechanisms located at opposite sides of said stack or pile, and thereby increase the capacity of the. machine for handling the articles.

Other objects of the j invention are to simplify and increase the efficiency of feeding mechanisms of this general character, and the invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

My invention is herein shown as applied to a wrapping machine of the construction illustrated in my co-pending application for United States Letters latent, Serial Number 650,091 filed on the 19th day of Sep; tember, 1911, and will be hereinafter specifically described with respect to'said maiping machine and 11 designates chine; but it- ,'will be understood the description of tie the speci adaptation invention is not intended limit the and scope of theinvemion.

in the drawings,-lfigure l. mentary side elevation of in for yrapping machines embol ir ventlon, taken on the line 1-7.

1 F 1g 2 is a sect on thereof on the i section on the line 22 o in a fragmentary partial side sle partial section of the feed Leech. & is a bottom plan VlEW of the and the parts associated there, is a section on the line 5 5 0; ing downwardly. Fig. 6 is i the shelf or bracket which supports tne i ous parts of the feed mec c n,

As shown 1n the d'rawi 10 a -vertical portion of the fianie n a no r shelf or bracket which entends therefrom and is attached thereto b so extending through a flange 12 of theora ket, l4 designates a vertically arranged chute above and supported on. said bracket in :which sticks of gums a, or other articles to be wrapped, are arranged in a verticalstach in such manner that said articles may be fed or removed one at a time from the lower end of the stack.

15, 15 designatewrapper magazines ranged one at each side of the chute 1%., each arranged to contain compressed bundles 1 of wrappers b that are adapted to be fed as one at a time from the magazines into the path of the articles to be wrapped by means the feed roller 16, as clearly set forth in my aforesaid application.

The gums or other articles a of. the yertical stack rest upon a carrier 18 beneath the bracketll and twhich has a limited reciprocatory movement beneath the chute 1e. Said carrier constitutes the bottom of the chute and 'supports'the weight of the stack of gums a. The carrier 18 is spaced at such 'distance below the bracket as to constitute between the same and the bracket a horizontal way 19 through which the gums orv other articles are delivered from the stack to the Wrapping mechanisms. The said car rier' isot skeleton form, as best shown in Figs. 4 and 5, it having a central longitudinal opening, and it is supported onand is guided by a pair'of guide rods 20' which ar not.

supported at their ends in the trams members 9.1 21 arranged. below the bracket 11, and attached to the frame, as by means oi the 22, 22; the said carrier having integrally formed bearings 28, 23 on their lower sides which are apertured forthe passage of the guide rods 20 therethrougli, The outer ends ot the feed slots or ways are formed between the frames 21 and bracket 11, as shown in Figs. 1 rind 3.

25 designates on ejector bar that slides through the teed slot or way 19, said ejector bar serving to deliver the gums or other articles from the stack. to the wrapping mechanisms. ejector bar is herein shown as arranged to deliver the gums alternately from the lower end of the stack a to the two mechanisins and in this construction the ejector bur passes beneath and entirely beyond the chute let in each reciprocation thereof so as to feed the next gum of the steel; in the next or return movement. of said bar. The only parts of the wrapping mechanism herein shown are the wrapping heads which are understood to be operated in the same manner as set forth in my aforesaid prior application and need not be further herein described" One feature of my invention resides in means for delivering the gums or other articles from a central chute to two wrap ping or other mechanisms located on opposite sides of the chute thereof. in such construction the ejector bar slides entirely across the lower end of the stack of gums or other articles in one movement thereof to carry one gum to the wrapping mechanism toward which it travels, ellows another to fall into the path of said ejector bar as to be torced from the stack toward the other or opposite wrapping .neclmnism in the return movement the ejector bar. The said ejector bar 25 is'given "motion through the following mechanism: 32 designates a guide rod, at the side of the machine below the shelf or bracket 11, said rod being slidingly supported in lugs 33 on the vertical frame plate 10. 35 designates a crank disk which is fixed on a rotating shaft 36 and said disk is provided with an eccentric stud 37 which operates in a verti-' cal groove 38095 the yolre 39 of a connecting member 40 that is connected at its other end to the ejector bar in a munner'presently to be described. Said connecting member 40 is attached to the guide rod 32, said member being shown as provided with an apertured, hub-like bearing 48 through which the rod extends and. to which it is pinned or other- The movable carrier is given a limited movement at the beginning of each reciprocation oil-the ejector bar, in the same direction as said bar, with the result that the inertia due to the changing of the gums a from a state of rest to motion is more reed ily overcome than if the carrier or gum Sll" port be stationary, thereby diminishing the shock brought on the gums and reducing liability of crushing of deforming the gums, The means which 'I have herein shown for thus giving zilimited movement to the carrier 18 comprises a lever arm 46 which is pivotally and loosely connected at its upper end to a stud 47 formed on a lateral extension ll at the inner side of said carrier 18, said lever arm'being provided at its lower end with a bearing s eevc 48 which is mounted to rock on short shaftdi) that extends outwardly from the machine frame 10. A second lever arm 50 is made integral with and extends rearwardly from said sleeve 48,

and is provided at its rear end with a leterally directed lug 51 which travels in a cam groove 52 formed on the inner face of the disk 35. Said cam groove 52 embraces u concentric portion c consisting of approximately one-half ct a circle and two equal length eccentric portions c,'0 which meet Eacyh other in the plane or the axis of the The parts are shown in Fig. 1 with the ejector bar 25 and carrier 18st one limit (if the movement thereof, the ejector bar having delivered a guru into the right hand holding head 30. in the continued movementof the disk 35 the said ejector plate and carrier will travel toward the left hand wrapping mechanism,.the ejector bar moving more rapidly than the carrier. The carrier travels in the some direction with the ejector bar through substantially one-quarter of the rotation of the disk 35, (or whilethe stud 51 is traveling through one-half of theeccentric portions 0) and is moving beneath the stack of gums at the time the ejector bar strikes the lower gum of the stack; and will continue too to move until the ejector bar engages with and has brought the lowermost gum into motion toward the wrapping mechanism. The carrier remains stationary while the stud 51 is passing through the concentric portion of the cam groove during about onehalf of the cycle of operation 'of the machine. By reason of the movement of the carrier beneath the gum which is to be next ejected. gtrom the stack the friction between said lower gum andsthe carrier is greatly reduced as compared to the conditions which would exist. ifthe carrier be stationary when the ejector bar strikes the edge of the gum.

The wrappers Z; are discharged by the feed rollers 16'downwardly through 0penings 55 formed between sliding spring controlled plates 56 and outer edges of the openmasses ings formed in the bracket Said wrappers are deposited across the gum way or slot upon supports 58 which extend inwardly from the frame members 21.- The plates 57 are narrower than the openings 55 in the bracket 11 which receives them and the ends of the plates 56 are slidingly sustained between depressed portions 60, 60 at the ends oftheopenings in the brackets and cap plates 61 secured to the bracket. The movable plates 56 are drawn by the springs 63'toward the inner sides of the openings in the brackets, as shown at the left side of Fig. 6. They are forced out toward the outer sides of the openings 55 to partially bridge the outer sides of said open-. ings when the gums or other articles are deliver-ed to the folding heads by means of depending lugs 65 which are engaged by sides of the extension 47 at one side of the car rier and laterally extending lugs (it? at the opposite side of the carrier.

The ejector 25 is provided at its ends, when it comprises a double ended ejector or at one end when consisting of a single ended ejector, with the recesses 7 5, and is provided at the sides of said recesses, imme diately over the side rails or supports of the bracket 18, with projections 76 which engage the edges of the article as the ejector slides through the bottom of the chute. The constitute clearance spaces through which may be discharged fragments of gum or other articles that may break off from said articles and thereby prevent the fragments from clogging the gums or articles in said way. Said ejector is also provided at the sides of its ends with horns 77 which engage the ends of the gums or other articles and prevent said gums or articles from moving 'endwise, or laterally with respect to the travel of the ejector when under the influence of and the ejector.

The ejector member and the carrier 18, which latter constitutes the bottom of the chute and which supports the stack of articles in the chute, may be otherwise arranged and or 'anized with respect to each other to produce the result of giving movement to the carrier or support just before the ejector member, which is located above said carrier or support, strikes the edges of the articles in the hottomof the chute.
