.MACHINE FOR MAKING BRUSHES.

SPECIFICATION forming part of Letters Patent N o. 340,184, dated April 20, 1886.

Application filed April 11, 1885. Serial No. 161,888. (No model.)

-]0 all whom it may concern.-

Be it known that I, LEONARD YOUNG, of Sing Sing, in the county of Westchester and State of New York, have invented new and useful Improvements in Machines for Making firushes, of which the following is a specificaion.

My invention relates to improvements in mechanism for separating the tufts of bristles from the stock in the holder wherein it is contained, and for feeding said tufts forward, so as to be in easy reach of the operatives.

In the accompanying drawings, which being herein referred to form part of this specification, Figure 1 is a side elevation of my machine; Fig. 2, a plan view of the same; and Figs. 3, 4, and 5 are repectively enlarged plan view, inverted. plan view, and edge view of the sliding plate.

As shown in the drawings, A is the table or frame-work of the machine. The stock-holder B, for containing the supply of bristles, is secured to the top of the table A, at one side of the opening, in which the sliding plate 0 reciprocates. Said stock-holder is composed of two side pieces, b, which are curved inwardly to form a contracted throat, I), through which the bristles are removed, and a slide, 1), which is pressed forward by a spring, h to force the supply of bristles into the throat b, where they will be in contact with the notched edge of the sliding plate 0. The bristles are inserted in the stock-holder B, so that the length of the bristles will stand vertically, and so that the edge of the sliding plate 0 will come at or near the middle of the length of said bristles, and for this purpose an opening should be made through the top of the table directly under the space between the side pieces, I), and extending outward into the runway for the sliding plate 0. The bristles rest on the plate or platform a of the table, whereon their lower ends will be evenly butted and sustained on the same plane, so that the sliding plate (3 will uniformly catch every tuft of bristles atthe center of the tuft, and thereby producing a uniformity in the work. The plate a should be made adjustable up and down, so as to adapt the machine to use bristles of different lengths.

The sliding plate G is fitted to reciprocate endwise in guides in the top of the table A. Said sliding plate is composed of three plates or thicknesses, the upper and lower members of which are secured together, so as to remain immovable in their relative positions, and have an angular notch, 0, formed in one edge. The central member is divided crosswise into three parts, of which the forward plate, 0', reaches to or slightly past the notch c, and is provided with a hooked point, a as shown in Figs. 3, 4, and 5. Said forward plate, a, is made adjustable in position by means of the set-screw 0, so as to increase and decrease the opening left in the notch c, as occasion may require,- to enlarge or diminish the size of the tufts of bristles. The central plate, o of the middle member of the sliding plate has an endwise sliding movement that is independent of the other members, and the extent of said independent movement is governed by the position of the forward plate, c, and the fixed after plate, 0 which latter is secured to and between the. upper and lower members of the sliding plate. The forward end of the central plate, 0*,has a hooked point, e, which corresponds to the hooked point a of the forward plate, 0', so that when the central plate, 0*, is moved up into contact with the forward plate, 0, the hooked points 0 and c join together to form a gripe for holding a tuft of bristles 'securely while being fed forward. The central plate is provided with a pendent staple, c, to which a cord or chain, d, is secured. One part of said cord runs forward over a pulley, d, and is secured to the treadle D, and another part of said cord runs rearward over the pulley .d and is attached to aspring, (1 by which the sliding plate 0 is drawn back to its rearmost position. WVhen the sliding plate 0 moves rearwardly, the notch 0 will remove from the throat of the stock-holder B a tuft of bristles. Then by applying pressure to the treadle D its first impulse will cause the central plate, 0, alone to move forward into contact with the forward plate, 0, thereby bringing the hooked points 0" and 0" closely together,

as indicated by dotted lines in Fig. 4, andthereby the tuft of bristles-will be securely held. The continued movement of the treadle D causes the sliding plate 0 to move forward,

thereby carrying the tuft of bristles into easy I c, in one edge, an adjustable end plate, a,

reach of the disengaged hand of the operative. As soon as the treadle D is relieved from pressure, the spring cl will cause the sliding plate 0 to move back into its rearmost position, and in passing the stock-holder B the notch a will obtain a new tuft of bristles, thereby providing for a repetition of the operation just described. A clamping device, E, (for holding the brush-blocks F,)is attached to the table A, and a reel, G, for wire, is conveniently located on said table. Instead of the cord and springherein shown and described as the means for operating the sliding plate C, it is obvious that an arm,'operated by the treadle D, may be employed for that purpose. I claim as my inventi0n- 1. In a brush-making machine, a sliding plate, 0, composed of a top and bottom plate secured together and provided with a notch,

having a hooked point, 0, and a central plate, 0, having a hooked point, a, fitted between the said top and bottom plates, the said central plate, 0, having an endwise sliding movement that is independent of the movement of the slidingplate 0, but is produced by the mechanism which operates the latter, as and for the purpose herein specified.

2. In a brush-making machine, a stock holder, B, having curved side pieces, b, to form the contracted throat b, and the springactuated slide'b", in combination with the plate a of the table A, whereon the bristles are butted and sustained, as and for the purpose herein specified.
