WILLIAM oLAXToN BEAY,`0F NEWTON, MASSACHUSETTS- MACHINE.FOR SETTING LAClNG-STUDS. A'

SPECIFICATION forming part of Letters Patent No.A 261,527, dated July 25, 1882.

' Application niedMarch 15, Tese. (Nummer.)

To all whom it may concern: Y

Be it known that I, WILLIAM OLAXToN BRAY, of Newton, in thecounty of Middlesex and State of Massachusetts, have invented a certain new and useful Improvement in Machines for Setting Lacing Studs or Hooks,'of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to a machine for setting lacing studs or hooks; and it consists in a novel device for separating the studs during their passage down the inclined chute and insuring the delivery of one stud at a time to the action of theieedplunger.

lIt also consists in a novel construction of the inc-lined chute down which the studs slide on leaving the hopper.

The features of my invention will be readily understood by reference to the following description of the drawings, in which Y Figure 1 is a side elevation of a machine ernbodyin g my present invention. Fig. 2 is a horizontal section on line a: x on Fig. 1, looking downward. Fig. 3 is a horizontal section of the vibrating separator and its bearing on` line x x on Fig. 1, and Figs. 4 and 5 are respeetivel y a vertical section and an end view ot' the same. Figs. 6 and 7 are partial eleva` tions, showing the lower end of the inclined chute, and illustrating themanner of separating the studs. Fig. 8 is a partial plan, showing the junction of the inclined chute withthe curved roadway. Fig. 9 is a section of the inclined chute. Figs. Sto 9,inclusive, are drawn to a scale about two and one-half times as large as the scale ot' Figs. l and 2. 4 p

A is the bed of the machine, from the rear portion ot' which rises the gooseneck B, ex-L tending forward over the bed A, and having mounted in its front end the setting-plunger G, connected by a link to the forward end ot the lever D, pivoted to the upper side of' the goose-neck B, as shown. E is the hopper, se-

cured upon a shaft having its bearings in thel forked frame F, all the above mechanism being arranged and adaptedto operate substantially as shown and described in LettersPatent No. 212,124, granted to Mellen Bray February 11, 1879, and Letters Patent No. 244,738, granted to me July 26, 1 881.

A short horizontal shaft, I, has its bearings in the goose-neck B and the detachable plate J, and has -an oscillating motion imparted to Y it by means of the connecting rod or link G, attached at its upper end to the operating-lever D, and at its lower end to the lever H, made fast upon one end ot' the shaft I.

, Atv or near the center ot' the shaft I is secured the gear-wheel K, the teeth 4ot' which engage with teeth upon the feed-plnnger (not shown) and impart to said feed-plunger the proper reciprocating motion, all as shown and described in the last-mentioned Letters Patent before cited. p

The mechanism pertaining to my present invention is not contained in the foregoing description, but will now be described.

Upon the end of the shaft I opposite to the lever H is secured a small bevel-gear wheel,a, the teeth ot' which engage with a similar bevelgear wheel, b, secured uponone end of the r shaft o, to which shaft an oscillating motion is angle may be varied, and has its bearing in` the stand d, secured by the bolt e to the side ofthe goose-neck B.

, Upon the end of the shaft c opposite to the gear-wheel bis mounted the sleeve f, so fitted to the shaft c that it will turn freely thereon, said sleeve being provided with two pins or lingers, g and h, parallel, or nearly so, to each other and to the axis of the sleeve f, and projecting from the end thereof across the upper edge of the plate@l of the chute L, near its lower end.' The end of the shaft c is provided with a cross-piece, k, which lies in a Slot, l, cutv terial is interposed between the sleeve f andV the goose-neck B to produce friction on said sleeve and prevent itfrom being turned by the friction of the shaft c.

L is the inclined. chute, adapted to receive the lacing-studssfrorn the hopper E and guide them to the curved roadway M, said chute being supported at or near its upper end by the stand N, attached to the goose-neck B, and attached at its lower end to an ear, a, projecting from the piece o. The chute L is curved at its lower end into a direction at right angles to its upper end, and forms a vertical angle with the roadway M, which is made horizontal at its forward end and curved upward atits rear end to meet the chute L. This arrangement of the chute L and roadway M, whereby the necessity of a spiral twist in the chute L is avoided, I have described and claimed in another application of even date herewith.

The construction of the chute L includes a novel feature, as will be described. Itis composed of two metal plates or strips, t' and p, connected together by ties r, so arranged that the studs s will slide along the upper edge of the plate i, hanging by their hooked heads, as described in my application above referred to; but the plate p, instead of being fixed in a plane at right angles to the plate i, is secured in a plane parallel thereto, withits lower edge in such a position as to come in contact with the shoulders between the heads and shanks of the studs s, to prevent them from tumbling off from the plate i, and at the proper distance to allow of their free passage down the chute, all as shown in Figs. 6, 7, and 9.

The piece 0, before referred to, is so constructed as to form both sides or edges of the roadway M at its upper end, the advantage being that said edges can thus be kept in line, the portion t extending upward higher than the part u to prevent the studs s from being displaced as they turn the angle and enter the roadway M.

The operation of my invention is as follows: With the parts in their normal position, the studs s, as they slide down the chute L, will be stopped by the first one coming in contact with the finger g, which will be in contact with the upper edge of the plate z', as shown in Fig. 6. lt' now the lever D is moved to bring the parts into operation, the shafts I and c will be partially rotated, the sleevefwill remain stationary by friction of the leather m until the cross-piece k comes in contact with the sides of the slot I, when the sleeve f will turn with the shaft c, carrying the finger o away from the plate i, and allowing the first of the studs s to slide down into the roadway M, thence in front of the feed-plunger into the proper position to be fed to the setting-tools. At the same time the finger h will be brought down tothe edge ofthe plate 'L to preventany more of the studs s from followingthe first one, as clearly shown in Fig. 7. By a reverse motion the parts assume their former positions, the finger h is carried away from the plate t', the finger g brought down to the edge thereof, and the next stud in the line allowed to slide down into contact with the finger g, ready for the operation to bc repeated. It" the first stud in the line should not move upon being released by thc finger g, the finger It would strike it and start it down the chute.

The reason for interposing the sleeve f between the shaft c and fingers g and h is that with the parts proportioned as shown the angular movement of the shaft c would be too great were the fingers g and h attached directly thereto, but the bevel-gear a might be made smaller in proportion to the bevel-gear b, so as to give the shaft c the proper angularl movement, the sleeve j and friction-piece 'm dispensed with, andthe fingers gand 7L formed upon the shaft c, or attached thereto or to the cross-piece 7c, and still preserve the principle of my invention.

By this invention I produce an accurate separating device that will insure the feeding of one stud at a time to the setting-tools.

I am also enabled to facilitate the construction of the inclined chute, as by combining the parts, as described, it can be more readily bent to the desired curve.

lNhat I claim as new, and desire to secure by Letters Patent ot' the United States, is as follows:

1. The inclined chtite L, composed of the metal strips or plates t' and p, connected together by the ties 1*, with the plate l; in a vtrtical plane parallel to the plate i, and arranged with its lower edge in position to guide the stud by the upper portions of the shoulders between the heads and shanks ot' the studs when said studs hang by their hooked heads upon the edge of the plate t', substantially as and for the purpose described.

2. The combination ofthe inclined chute L, the shaft I, provided with the bevel-gear wheel a., the shaft c, provided with the bevel-gea-r Wheel b, the fingers g and h, connected to the shaft c, and means of imparting to the shaft I an oscillating motion about its axis, substantially' as and for the purposes described.

3. The combination of the shaft I, provided with the bevel-gear wheel a, the shaft c, provided with the bevel-gear wheel b and crosspiece k, the sleeve f, provided with the slot l and mounted upon the shaft e, a friction-pad adapted to bear against the sleeve c, thc fingers g and h, carried by said sleeve, the inclined chute L, and means of imparting to the IOC shaft I an oscillating motion about its axis,

substantiallyas and for the purposes described. Executed at Boston, Massachusetts, this 11th day of March, A. l). 1882.
