'HOPPERAND DELIVERYMECHANISM FOR STUDS.

SPECIFICATION forming part of Letters Patent No. 502,895, dated August 8, 1893. Application filed May 9, 1892. Renewed February 2, 1893- Serial No. 460,785. (No model) To all whom it may concern.-

MAN, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Hoppers and Delivery Mechanisms for Studs, of which the following is a specification.

This invention relates to improvements in that class of hoppers designed for containing lacing-studs, and having in conjunction therewith mechanism for bringing the studs from a promiscuous mass into a uniform arrangement for delivery.

The objects of the invention are to improve a hopper of the class indicated to the end of securing, in its operation, the utmost certainty of the required uniform arrangement for delivery of the studs and the greatest freedom of their delivery, all clogging being avoided.

The invention consists in the arrangement or combination of parts substantially as will In the accompanying drawings:-Figure l is a perspective View of the improved hopper showing the movable serrated plate as beginning its upward movement. Fig. 2 is a view similar to Fig. 1, the serrated plate being, however, shown as approaching the limit of its upward movement. Figs. 3 and 4 are perspective views of portions of the mechanism which will be hereinafter more particularly referred to. Figs. 5, 6, and 7 are vertical cross sections of the hopper mechanism with the parts thereof in various positions as assumed during different stages of the operations thereof.

In the drawings A represents the upwardly open hopper supported by and between the standards, B, B, the front wall of the hopper downwardly converging, substantially as shown. The rear boundary of the hopper is, in part, formed bya plate 0, which is adapted for a reciprocatory movement in a vertical plane, and, in part, by the plate D, whichis fixed to and supported by the rear of the stan dards, B, B. The upper edge of the said plate, 0, has a regular series of, serrations, a, the same being arranged to incline from'one end of the plate to the other, substantially as shown. The reciprocatory movement of the serrated plate is to be imparted in any manner which may be approved, a means shown merely to indicate said capability consisting in the handle lever, at, which is pivotally mounted on one of the standards, B, and has a connection with the plate C, through its engagement with the stud, w, on the angle piece, 113 which is attached to the said plate and to the vertically reciprocating cam -operating bar, a, which will be hereinafter referred to. The said plate is constrainedin its reciprocatory movements by having its vertical edges enter the vertical guide grooves, e, e, within the inner faces of the standards. The notches between the dividing portions of the serrations conform more orless nearly and peripherally to'the necks of the lacing-studs between their heads and shoulders, and the plate, D, as

clearly shown in Fig. 5, is in a vertical-plane rearwardly separated from the plane'of the plate, 0, by a distance about corresponding to the distance axially of the stud between the top and under side of the'head.

' There is, through one of the standards, B, as shown in all. of the drawings, an aperture,

zontal, as shown; and from the farther and outer side of the standard there is the beginning of a feed-way, E,. comprising separated and downwardly inclined parts, 01, d, with the slot, 01, between them for engaging the necks of the studs, as shown in Fig. 1, which slot by the edge of the bar, g, while the shank and shoulder of the stud, which latter divides the shank and neck, will have the sliding engagement with the edge of the bar, f.

It will be plain, by an inspection of the drawings, that with a quantity of the lacingstuds in the hopper, and the serrated plate so lowered that its upper edge is below the top of the mass of studs as seen in Fig. 5, those studs which are at the top and rearmost will dispose themselves above the serrated edge being rearwardly restrained by the said back plate,D. Now, on raising the plate, the serrated upper edge thereof will engage, by its neck, and in the disposition indicated, usually at least one of the studs, carrying it upwardly in the manner more particularly seen in Figs. 2 and 6. As the serrated studcarrying upper edge of the plate, 0, ap-

proaches and reaches the track-way constituted by the aforesaid bars, f, g, said bars have separating movements laterally relative to the plane of the plate, 0, the bar, f, having an extent of movement forwardly consider-,

ably in excess of the movement rearwardly of the bar, g. The separating movements of the said bars permit the studs which may be engaged by the serrated plate to be carried, without obstruction, above the run-way constituted by said bars, which latter, then, return to their normal positions, Figs. 1 and 7,

so that as the serrated plate next recedes downwardly toward its normal position the stud will come upon the top of the runway and be then free to slide or roll down thereon to and through the aperture, 1) and into the feed-way, E.

I will now proceed to describe the means whereby the separation of the said bars and the resumption of their approached 'position are accom plished: The said bars are sup-. ported at the lower extremities of paired arms,

f f and g ,g which at their upper ends are respectively fixed upon rock-shafts, 2' and j, horizontally mounted in suitable bearings of the said standards, said shafts projecting through and beyond the outer face of one of the standards and receiving the fixed, depending arms, and Z, each of which has projected toward the other, the members 15 and Z to receive the impingement thereagainst of the cam-surfaces, l0 and 12, which are formed at the upper extremity of the bar, m, which is connected to the aforementioned vertically reciprocating bar, 0, by a pivot joint as indicated at 'n. The cam-ended bar, m, at the completion of the upward thrust thereof has its swinging movement away from the face of the standard so as to be carried entirely out of engagement with the impingement members, 70 P, of the rock-shaft arms to permit the bars, f and g, to resume their approached positions (from which they had been forced by the cam- surfaces 10 and 12, acting on the arms, In and Z) by reason of the bar being impinged upon by,or itself impinging against,the projection, 0, which stands out from the face of the standard at a suitable height relative to the height of the members, 70 and Z of the rock-shaft arms. The said arms, 70 and Z have the retracting spring, 19, applied thereto, substantially as shown for bringing them together when permitted by the retirement of the cam-ended bar from the members of said arms.

The reciprocatory bar, 0, and the cam-ended bar, m, which is pivoted thereto, are constrained in their proper movements vertically alongside of the standard by the apertured blocks,q and 1 the aperture, g ,in the latter being considerably wider than the thickness of the bar, m, so that even before the pivotjoint, 01, rises above the block, 1 said bar, m, may commence to have its outward swinging movement. The spring, g, maintains the bar, on, closely against the face of the standard, except when the bar is upwardly forced by the means described.

The degree of normal separation between the track-bars may be determined by the adjustment of the screws, 25, t, which by their abutment against the projected piece, 0, limit the approach of the arms, 70 and Z, and consequently the approach of the track-bar carrying arms, f 2 and It will be observed that the series of regularly arranged serrations, to, terminate just within the upper corner of the plate, 0, which is next to the stand ard which has said aperture, 1); and that such corner is somewhat upwardly extended above the generalline of arrangement of the series of serrations, as seen at at, its top edge being in the form of a cam downwardly and inwardly inclining, as seen. The purpose of this formation is to prevent more than one stud from lying at the base of the curved portion, a; that is, to cause a stud which may incline to lie on the stud which is in the base of the recess next to part a to fall off into the hopper.

By the formation of the cam-impingement portions, 70 10, and Z 12, the timing of the separating movements of the track-bars, f and g, is assured so that, as already mentioned, the bar, f, has a considerable portion of its movement forwardly before the bar, g, begins to move rearwardly. The object of such manner of operation will be thus explained:- if a stud, brought up by a previous upward play of the serrated plate, and settling on the track-way fails to roll down such track-way clear awayfrom over the hopper, before the next operation of the mechanism, should the rear bar, g, move rearwardly while the shank of the stud is still supported by the forward bar, f, the stud would be carried rearwardly and be jammed into the border of the aperture, it, formed in the back plate for the accommodation of the bar, g; but because of the movement of bar, f, earlier than that of bar, g, the forward support for the remaining stud is removed, and then its shank end will swing down and the stud will fall from engagement with the bar, g.
