FACING AND STACKING MACHINE Application filed February 19, 1929. Serial no- 341,239.

' The present invention relates to improve- 10 bottom, and a somewhat. irregular top connecting with the bottom through a rounded edge, and this formation is effectively used in carrying out the present invention.

The objects of the invention are to mechanically, at high speed, with few operators and at'little cost, effectively and accurately position successive snaps, cookies or similar articles with corresponding faces all in the same direction,.whereby packers will be fafor arranging the faced snaps or cookies in overlapping upwardly inclined relation,

line or stacked snaps and with slight manipulation form a stack or roll with all the surfaces in contacting parallel relation.

WVith the above mentioned and other oby p members 11 extended upwardly from the jects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion,

size and minor details of construction within embodiment of my invention, illustrating the cilitated in packaging the goods; to reverse whereby an operator or packer may grasp the same consisting of aplurality of. duplicate units. 1 T

Figure 4 is a View similar toFigure 3, with the parts acting on a faced snap. 7

Figure 5 is a view in detail planof one of; the stacking rollers and its associated spring fingers. V

"In the drawings, the numeral l indicates a" supporting frame, consisting of the'top side lower or platform forming member 4.

' Above one. end of theframe" is positioned an'elongated open topped hopper 5, the bottom of which is inclined and is formedj'on frame members 2, supp'orting'leg's 3 and a its upper surface with steps6, each stepbei'ng of a depth slightly greater ,1 than the thickness of the snap the machine is designed to handle. The lower end of thehopper, 'immediately above the bottom, is formed with a discharge slot 7 ."The steps and slots are illustrated in parallel rows, being separated by dividing walls 8.' Transversely of its-upper end, above the uppermost 'step,-the-hop-" per is provided with a transverse rod 9 from' which depend fingers 10 between which the snaps pass in their downward travel and; are therebyformed into rows, one in alignment with 'each row of steps. The'rear end of the hopper is supported by flexible strap members 2, and the forward end of the hop--' per is supported at each side by a roller 12 on the lower end of a mounting "membenl3, the rollers riding the members 2. p o

Rapid longitudinal vibratory movement is imparted to the hopper '5' to cause the con on the upper surfac' eof rear oFFrcE j tov tents thereof to pass downwardly therein'and discharge fromthe apertures 7 This is accomplished by a link 14' pivotedat 15 to the hopper and connected at its opposite end with an eccentric 16 on ashaf t 17 p To insure rows of snaps of'a single thick ness orheight discharging from the aper tures 7,1 mount transversely of and within the hopper 5, a relatively flexible rotary brush 18, the lower periphery of which is spaced from its associated line of steps a distance slightly greater than the thickness of one snap but less than the thickness of two snaps. The brush is rotated in a direction reverse to that of the travel of the snaps by power from less conveyor belt 22 of a width slightly greater than the width of the hopper, said belt at the ends of its flight, upper and lower, operating over the rollers 23 and 24. The upper flight ofthe belt is divided approximately midway of its length into the primary v and secondary flights 25 and 26.

The sna s or articles discharge through the ures into parallel rows onto one end the primary section 25 of the upper flight 1 of the endlessconveyor, and are conveyed therebybetween guide plates 27 to a point beneath a facing roller 28, Fi s. 3 and 4. These rollers, one being provided for each row of snaps, are carried on a transverse shaft 29, and are constructed of relatively soft sponge rubber. The rollers are so positioned above the primary flight 25 as to afi'ord a space between their peripheries and the'upper surface of the flight, of a thickness slightly less than that of the snaps being handled As clearly illustrated in Figs. 2, 3 and 4, the primary flight 25 terminates by passing over a roller 30 at a point inwardly from a lim disposed vertically through the far side of tlm peripheral edge of the rollers 28.

Disposed transversely of the secondary flight 26, at a point slightly beyond, above and parallel with the end of the primary flight 25 is a roller 31 on a shaft 32 and rotated in the direction of the arrows, Figs. 3.

and4.

With the endless belt travelling in the direction of the arrows, Figs. 3 and 4, and with.

- rollers 28 and 31 rotating in the direction of their indicatin arrows, the action of facing the snaps is clearly illustrated as follows. P

Referring to Fig. 3, wherein a snap A is conveyed by the primary section of the belt in an upside down position, it will be observed that it passes beneath the elastic roll 281ml as the trailing portion of its rounded e e B reaches the declining curvature of the rol I r 30, the snap is inclined with its forward edge upwardly disposed and it thus leaves the primary belt section in this position, dropping by gravity to the dotted line position C, Fig. 3, where the action of the roller 31 causes a pressing of the lower edge of the snap onto the forward end of the secondary flight 26 of the belt 22, and said lower edge striking the belt, the snap is caused to travel, lower edge first, and thus be reversed in its position from that illustrated in full line on the primary flight 25. This action is accomplished by the rounded edge of the snap riding over the curved surface of the primary flight as it passes over the roll 30.

It will be observed in Fig. 4 that a snap deposited on the primary flight 25, in a right side up position, is discharged from the end of theprimary flight at a point where it passes around the roller 30, with the forward edge of the snap inclined downwardl it having dropped beneath the surface 0 the roller 31, and as it is discharged by the roller 28, it drops right side up onto the secondary flight 26 of the belt 22.

It will be thus observed that the parallel rows of snaps are all correspondingly faced as they are deposited onto the secondary flight 26 of the main conveyer belt 22, and when in such position they are conveyed toward the discharge end of the secondary flight 26, and pass beneath the conveyor rollers 33, preferably of yieldable sponge rubber, the rolls being mounted on a shaft 34 rotated to drive the rollers in the direction of the arrow 35Figs. 3 and 4.

Arranged in parallel alignment with each row of snaps is a concave trough 36 best illustrated by shading and end of trough in Fig. 5, and projecting into the end thereof, one disposed on each side of its respectiveroller 33, are friction spring fingers 37 carried by a plate 38 on a rod 39. Projecting into each trough, beyond the ends of the fingers 37, is a stacking spring 40, the action of which is to retard travel of the snaps longitudinally of the trough, and to enable the action of successive snaps, asthe same pass beneath the fingers 37, to ride on preceding snaps and thus assume inclined overlapping relation, as in Fig. 3.

The respective parts of the apparatus are actuated by a motor 40 which operates, through a band 41, a driving wheel 42 on a shaft 43. On said shaft is a pulley 44 connected through belt 45 with the cam shaft 17. A belt 46 operating over a pulley 47 on shaft 48 which mounts pulley 23 over which belt 22 operates, causes the travel of belt 22 in the direction of the arrowsFigs. 3 and 4. Batteries of rollers 28 and 33 are driven in the direction of arrows 35, Figs. 3 and 4, by a belt 49 operating over rollers 50 on the ends of shafts 29 and 34, the belt being driven by pulley 51 on shaft43. Shaft 21. operating brush 18 is driven by a belt 52 from cam shaft 17.

I claim 1. An apparatus for facing snaps and the like, comprising a vibrating hopper provided with a stepped bottom downwardly inclined toward one end and communicating with a discharge slot in the lower end of said hopper, means within the hopper for acting V on the snaps to remove from said bottom steps all snaps excluding a single layer, an advancing and supporting means onto which the snaps discharge from the hopper with one face resting thereon, and means at the end of said advancing means for reversing any snaps presented thereto in an inverted position.

2. An apparatus for facingsnaps and the portion thereof and in spaced relation to the belt, and adapted to interrupt momentarily the forward movement of the snaps which were received with bevelled face'downward on the upper belt section.
