To all whom it may concern Be it known that I, GUSTAV E. He ress, a citizen of the United States, and a resident of Waterbury, county of New Haven,

"and State of Connecticut, have invented certain new and useful Improvements in Machines for Feeding Safety-Pin Shields and the Like, of which the following is a full and clear specification.

This invention relates to machines for feeding safety pin shields and the like, the primary object being to provide an improved construction, combination, and arrangement of parts in a machine of this character by means of which the articles can be lifted out of a mass one by one and preferably delivered in a manner which will adapt the feeding mechanism to correlate with other mechanisms in assembling the parts of a completed article of merchandisc such for example as a safetypin.

More especially, the present invention contemplates an improved mechanism for tilt feeding safety pin shields in suitable relation to the other parts of safety pins with which they are to be assembled.

Other and further objects will appear in the specification and be pointed out in the appended claims, reference being had to the accompanying drawings in which. my invention is exemplified in its adaptation to a safety pin machine.

In the drawings,--Figure 1 is a front ele vation of one embodiment of my invention, parts being broken'away; Fig. 2 is a top plan view of the same; Fig. 3 is a vertical section of the same, parts being omitted and parts shown in elevation; F1 4 is a fragmentary front elevation of t 1e lower portion of the hopper and with the front wall removed; Fig. 5 is a section on the line V-V, Fig. 1, parts being shown in plan; Fi 6 is a fragmentary rear elevation of t e annular gear conveyor; Fig. 7 is a fragmentary front elevation of the cam ring; Fig. 8 is a fragmentary detail section of the-annular gear and cam ring; on the line VIH-VIIL Fi 1; Fig. 9 is a similar section at the top 0 the ring,certain contiguous parts being shown in elevation: Fig. 10 is a fra mentary front elevation of the gear ring s lowing interlocked shields: Fig. 11' is a vertical longitudinal section of the-chute; Fig. 12 is a plan view of the same; Figs. 13, 1-1, loand 16 are sections on the lines XIIL-XIII, XIV -XIV, XVXV and XVI-XVI respectively of Fig. .12. Referring more particularly to the drawings, in the embodiment shown therein a hopper is provided comprising a storage section 1 with a sloping bottom 2, which may be mounted on any suitable support by means of a base flange 3 which is connected to the hopper by means of a web 2 and a delivery portion 5, into which the articles are fed, n the present instance, shields for safety pins. Said portions of the hopper are separated by a partition 6, provided ad acent the bottom of the hopper with an opening 7. The opening 7 may be closed or opened to any desired extent by means of'a shutter 8, having a handle 9 which is accesssible from above, as shown in Figs. 1 and 3. Within the delivery portion 5 of the hopper, the bottom walls 10 converge in such a way as to cause the shields to fall edgewise into a series of recesses or pockets 11, as shown most clearly in Fig. 4-. Said pockets or recesses are comprised in a conveyor which is adapted to remove said shields one by one from the mass and to elevate them to a suitable point of delivery from which they are conveyed by a chute in the manner to be hereinafter explained; Preferably, said conveyer is constructed in the form of an annular gear 12 for the purpose of simplifying its embodiment with a working machine, the present embodiment of said gear being designed to receive its motive power from a worm 13, which is keyed to a shaft 14-. Runnin loosely on one end of the shaft 14 is a pul ey 15 which is driven by a belt 16. Said pulley is adapted to transmit )OWBI to the shaft 14; by means of a suitable clutch element 17, which coiiperates with a clutch element 18 formed integrally with the ulley 15, said clutch element 17 being splmed to the shaft It in the manner indicated. Simple and eflicient means for reciprocating the element 17 of the clutch, is provided by a hand lever 19 which is pivoted at 20 and provided with an upwardly deflected arm with a rounded extremity running in the groove 22 of the clutch element 17. The shaft 14 is journaled in suitable bearings '23 formed in any suitable portion of the frame of the machine. As shown in Figs. 3, (3, 8 and-9, the annular gear 12 is pro vided with a series of small circular holes 2%, which are arranged in a circle so that each hole 2% is centrally disposed with respect to a pocket ll. Furthermore, a shield 25 when properly disposed in one of the pockets 11, that is with the rounded end downward, will be in suitable position to have a pin or plunger 26 projected into the rounded central opening in said shield, as shown clearly in Fig. 10. Each of the pins M3 or plungers 26 is rigidly mounted upon a piston 27 of larger diameter than the pin 26, said pistons being reciprocably mounted in correspondingly arranged recesses 28. Between the inner wall of each oil said recesses and the pin 27 therein, is disposed a spring 29, the normal tendency of which is to force the piston 27 to the right, according to Figs. 3 and 8, and to retract the pin 26 from engagement with the shield which an maybe in the socket-l1 at the time.

in order to provide simple and eficient means for operating these pistons at suitable intervals in carrying out the purposes or? these parts, a cam ring 30, preferably as tired in position, is disposed immediately behind the annular gear 12. As indicated in Fig. 7, the cam ring 30 is adapted to permit the pins or plungers 26 to lie in retracted position throughout approximately threeso fourths of an entire revolution, the remaining portion 31 being gradually beveled toward the ring gear 12, so that as said gear travels over that portion of the cam rings, the plungells 11 are gradually forced into as the sockets or recesses 11. By an ins ection of Figs. 1 and d, it will be understood that after a shield 25 has traveled more than from the position shown in Fig. 4, the pluner 26 will begin to enter the central 0 en- 4e mg therein, thus preventing the shield rom fallingout of position during the upper portion at its upward movement. During the first portion of this upward movement, the term of the shield and the pocket 11 co- 46 operate to retain it in position. On the other hand, whenever it happens that the open end of a shield becomes inserted into a socket 11, the plunger 26 durin the upper art of its movement, will be orced inw wardly without engaging the shield 25, and

'hence said shield wil into the hopper, the purpose of this function of the machine being to deliver the shields to the chute to be hereinafter re- 65 terred to, with their branch ends extending forwardly in the direction of movement down said chute.

Referring now to Fig. l, a gear 32 which is of, peculiar form to adapt it to mesh with W the ring gear 12, is provided with a rigidly attached rope pulley 33. The gear 32 and pulley 33 are preferably journaled upon a suitable shaft 34 projecting from a bracket 35, as shown in Fig. 3, a portion 5 of the W5 hopper is provided with a bearing boss 36,

be free to fall back aliases within which is a stub shaft 37 for mounting an agitator in the form of a hub 38, from which project a plurality of radial flexible arms 39, said arms being preferably constructed of coiled spring wire to adapt them to drag over the mass of shields without injury to said shields. lln this manner, the mass is agitated in a manner suitable to segregate the. shields and cause them to drop into the pockets or recesses 11. A grooved pulley 41-0 is formed solid with the hub 38 to adaptpower to be transmitted from the pulley 33, by means of a rope drive d1. Also rigid with the hub 38, is another grooved pulley 42, over which runs a rope or belt 4-3 (see ll ig. 1), the rope 43 being adapted to transmit power to a pulley 4a which is journaled in'a bracket to. The pulley it is preferably constructed of soil: or resilient material, and provided with teeth 46, which as shown in Fig. 9, adapts said toothed alley to engage the lower one of a pair of interlocked shields 25, it being not uncommen for said shields to become interlocked in the manner illustrated in Fig. 10. llt is necessary to embody some such device as this, since should the interlocked shields be discharged into the chute, serious diiliculty and probably damage would result therefrom. In order to provide simple and ellicient means for preventing shields 25 from being jarred fromthe they have'been elevated cm the hopper, ll preferably employ an arcu'ate plate or strap 47. Said late 47 terminates adjacent the' highest point of the rin. gear 12, since at this point the piston 27%1as been suddenly released at the end of the beveled portion 31 of cam ring 30 so as to permit the shield which is held by the plungers '26, to drop into the upper end or the chute t8, said chute bein suitably arranged to convey the shield orward in the manner now to be pointed out.

Referring now to Figs. 11 tolfi inclusive, the chute 48 is provided with a groove or channel which comprises in the present embodiment, a portion 49 of substantially llshaped cross section (see Fig. 13), a broadened'V-shaped portion 50 (see Fig. l-l), acombined U- and V-shaped section 51 (see Fig. 15), and a ll-shaped section with an 'overhangingledge, as shown at 51 in Fig. 16. As shown in F igs. 12 to 16, as well as certain other figures hereinafter. described, each of the shields 25 comprises a relatively light branch '52 and a relatively heavy branch 53. It will furthermore be evident that the feeding mechanismdescribed above, may act to deliver said shields with'tlie heavy branch on eitherside ofthe chute 4d, as represented by the two adjaoently disposed shields at the right of Fig. 12. do

fplungers 26 after" t ll its

cordin to the present embodiment oi my invention, the correct arrangement is shown nuance other shield which is incorrectly disposed,

will likewise travel through the chute with the exception that the lighter branch 52 will slide over the left hand incline when it reaches the V-shaped section 14 of the chute. The last mentioned shield, as it nears that portion of the chute adjacent the section line XV-XV, will however become shifted by reason of the channel or groove in the chute being contracted into the form shown at 51 in Fig. 15, the lighter branch 52 being in consequence of this formation, cause to revolve about the heavier branch 53 into the position shown in Fig. 15. Hence, after the shields. have passed the section line XV-XV, all of them will lie in the chute 48 with their branches in the same relative position.
