BRUSH-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 669,754., dated March 12, 1901.

Application filed June 25, 1900l Serial No. 21,547. (No model.)

To all wtmn/ it may concern:

Be it known that I, FRANK J. LE DUC, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement. in Brush-Making Machines; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object a brushmaking machine of superior efficiency and utility; and it consists of the construction, combination, and arrangement of devices hereinafter described and claimed, and illustrated in the accompanying drawings, in which- Figure l isa front elevation. Fig. 2 is a side elevation. Fig. 3 is a View in horizontal section on the line 3 3, Fig. l. Fig. 4 is a plan View. Fig. 5 is a view in section on the line 5 5, Fig. 2. Fig. 6 is a View in Section on the line 6 6, Figs. l and 7. Fig. 7 isa vertical section through portions of the device on the plane 7 7, Fig. 3, but showing features above the horizontal section on which Fig. 3 is taken. Fig. 8 is a view in vertical section on the line 8 8, Fig. 4, showing portions of the staple-forming mechanism.

The object of my invention, more particularly, is to provide a machine for forcing a bunch or tuft of stock into a suitable socket in a solid brush-head and to drive a staple thereover into the head to confine the stock in place. To this end my machineis intended to feed the stock under a reciprocatory driver, whereby the stock and staple are driven into the brush-head, also means for feeding the wire from which the staples are formed, and mechanism to form the staples and feed them into position for driving into the head.

My invention also includes novel driving mechanism.

My invention, moreover, includes the general construction, arrangement, and operation of parts herewith disclosed.

I carry out my invention as follows:

In the drawings, c denotes any suitable supporting-frame, in which is journaled a driving-shaft b, provided with a pinion c, meshing with a gear d upon a shaft e. The drivingshaftb is shown provided with a drivingpulley f, belted by a belt g with any suitable source of power. A connecting-rod 7L, at one end thereof, is eccentrically connected with a disk L' upon the shaft e. At its upper end said rod is connected with a level-j, fulcrumed at its rear end upon a standard k. This leverj, as will be seen, is actuated by the connecting-rod h.

Upon the forward portion of the frame are located standards ZZ, preferably projecting forward at their upper ends and converged, as shown in Figs. l and 2, their upper extremities being united by a cross-piece fm. Intermediate their ends they are also united by an additional cross-piece n, which also projects forward of the standards Zt, as indicated in Fig. 2. Through the cross-pieces m n reciprocates a plunger p, carrying a driving-spindle q. The plunger is constructed intermediate its ends with an elongated orifice, (indicated at ig) into which the forward end of the lever]` projects, the lever having a requisite free movement in engagement with said plunger owing to the forward end of the lever having an oscillatory movement. The rod 7L may be connected with the leverj in any suitable manner, as by a yoke s. A table t is attached to the forward portion of the frame, provided withan oriflce u, through which the driving-spindle may pass in its operation. The table is provided at the front and rear thereof with lateral guide-plates w w toward one extremity thereof to hold the Aends of the stock in place, the front guideplate being omitted in Fig. l.

To assist' the operation of feeding the stock into proper position and to hold the stock down properly upon the table, I also provide an upper guide or cover 0c, provided with an upwardly-curved projecting guide-arm y, to facilitate the introduction 'of the stock in place upon the table t, and with downwardlyprojecting wings or flanges fu fu, having their lower edges spaced fron the table, as shown, to permit a bunch of stock being engaged thereunder.

Upon the table t is a reciprocatory pusher- IOO arm a to push the stock forward underneath the driving-spindle q. Over the pusher-arm z is a plate, (indicated at the numeral 8,) having its forward end turned downward and bifnrcated, as indicated in Figs. 6 and 7, to form a guide-opening at 9 and having downwardly-projecting arms or prongs 1 and 2, Fig. 6, on either side of said opening, through which opening the reciprocatory arm z may pass. A cover plate 10 is also provided, located over a portion of the plate 8. It will be perceived that forward of the plate 8 is thus formed a stock-receiver space or opening between the forward end of said plate and the guide-arm y, (indicated at the letter o, Figs. 1 and 7,) into which opening a hnlich of stock may be placed by an attendant and forward of the retracted end of the pusherarm z. The table t, it will he understood, is stationary and the stock is placed upon an immovable portion of the machine, the pusher-arm z pushing the stock into place on the immovable table under the driving-spindle q. The attendant may not only place the bunch of stock in the opening o, but may also without difficulty or hindrance force the bunch of stock under the wings or flanges U o.

I do not limit myself solely to any particularmechanism for actuating the reciprocatory pusher-arm z, but, as shown in the drawings, a lever 11 is provided, fulcrumed to the frame, as indicated at 12, the forward end of the lever 11 being properly connected with the arm a', as indicated at 13.

Engaged upon the lever]l is a yoke 14, said yoke provided with arms 15 and 16, projecting downward on each side of said lever. With the arm 16 is pivotally connected a cam-plate 17, as shown at 18, said cam-plate bearing against the rear end of the lever 11 to actuate said lever, and thereby actuate the pusherarm e.

A staple-runway is indicated at 19. To form the staple, the wire (indicated at 20) is fed over the rear arm of the runway. Asuitable plunger 22, carried by the leverj, forms the staple upon its descending movement, said plunger cutting the wire at the sameV time of proper length to form the staple. To force the staples off from the arm 21 when formed, I provide a bell-crank lever 23, provided with forwardly-projecting arms 24, connected with the lower end thereof, as indicated at 25. Said lever 23 is fulcrumed upon a bracket 26, as indicated at 27. To actuate the lever 23, the con meeting-rod 7L is provided with an arm 29, constructed with a beveled projection (indicated at underneath the upper end of the lever 23. It will readilybe seen that as the beveled projection 30 contacts with the upper end ofthe lever 23 in the upward movement of the rod 7?, the bell-crank 23 willbe actuated to force the staples olf from the horizontal portioirof the runway, the staples thereby descending into position under the driving-spindle q, the staples being received upon one end of aspring-arm 31. Upon the descent of the driver the staples will be forced off from the extremity of the springarm and into place in the brush-head.

To the arm 15 of the yoke 14 is rigidly con nected a cam-plate 28. The cam-plate 17 has a movement similar to that of the connectingrod h-viz., a vertical movement and a laterally-oscillatory movement.

To feed the wire, the supporting-frame ais provided with a bracket or table 32. Upon a slide 37 is carried a standard 33, provided with a dog 34, fulcrumed thereto, provided with downwardly-projecting arms and 36 to grip the wire. This slide 37 is actuated by a lever 38, fulcru med to the frame, as indicated at 39, said lever heilig actuated by the caniplate 28. rlhe slide 37 reciprocates in agnideplate 39a. Said guide-plate and the table 32 are provided with upwardly-projecting flanges 40 and 41, through which the wire is fed, a weight 42 engaging the wire, preferably between said flanges, shown in Figs. 1 and 5. The lever 38 is provided adjacent to the arm 36 of the dog with a beveled face, as indicated at 43. It will be perceived that as the lever 38 advances toward the dog the arm 35 of the dog will thus be tilted downward to grip the wire to feed the wire forward. The return movement of the lever 38 releases the dog from gripping the wire, the wire being held from retracting by the weight 42 as the slide carrying the dog recedes.

To govern the movement of the wire so as to regulate the size of the staple desired, the lever 38 may be provided with a gage-arm 43, which may be adjusted toward or from the cam-plate 28. A guide-arm 44 may also be employed through which the wire is passed.

At one side of the opening u, is a stop 45, the stop being located on the side of the opening opposite the pusher-bar and serving to hold the bunch of stock from being pushed too far, the stop confining the bunch of stock in proper position under the driving-spindle as the pusher-arm advances, forcing the stop into position. A portion of the framework, as indicated at 46, is also carried forward under the driving-spindle and provided with an orifice, as indicated at 47, through which the staple passes to engage astride a bunch of stock forced into position thereunder.

To hold the staple in position, the orifices u and 47 are provided with marginal recesses, as indicated, for example, at 48 and 49. Underneath the table z5 is a shoulder 50, provided with an orifice 51 therethrough, through which the stock and staple are carried to the socket in the brush-head. This orifice of the shoulder is also provided with recesses 48 and 49. The stop 45 is provided with one ofthe grooves, 4as indicated at 49, while the forward end of the pusher-arm is formed with a corresponding groove 48. When the pusher-arm z is advanced to carry the bunch of stock into position, said arm remains up in forward position until the staple passes between it and the stop 45, so as to assist in guiding the sta- IOO IIO

ple as it is forced downward. After the staple passes the end ofthe pusher-arm said arm is then retracted, affording opportunity for feeding an additional bunch of stock into the opening o. Byhavingthe pusher-arm remain up in advanced position before returning until the bunch of stock forced forward thereof is forced downward-with the staple asti-ide thereof it assists materially in guiding the staple to the work. vVhen the pusher-arm recedes, it remains in retracted position for an ample time to feed a bunch of stock into the opening o.

A customary support o r table (indicated at 52) is employed, upon which the brush-head is located, beneath the driving-spindle. This support or table 52 may be arranged and constructed in any suitable manner. I prefer to connect the rear extremities of the levers 11 and 38 by a spring (indicated at 53) to retract said levers. It will be perceived that all of the working parts of the machine are actuated from the connecting-rod h. The cam 17 is preferably connected to the rod h by a bar 54 to give to the cani the motion of the connecting-rod h. A stop 55 is also provided to limit the retraction of the push-bar e. The lever 1l is preferably connected to the pushbar by an intervening link 56, or otherwise, as may be desired.

The operation of the machine will now be understood. The machine being in motion, a bunch of stock is fed by the attendant into the opening o and may be forced by the attendant under the wings or iianges 'u c of the' cover The pusher arm then advances, forcing the bunch of stock firmly against the stop 45 and under the Wings v c between the openings u and 47. While the pusher-arm is in advanced position, as above described, the driving-spindle descends, forcing a staple through the opening 47 astride the bunch of stock, and as the driving-spindle further descends the bunch of stock, with the staple, is forced downward through the opening/u,` and through the opening in the shoulder 50, the bunch of stock being thereby folded. A brush-head upon the table 52, having a socket suitably adjusted under the shoulder 50, receives the bunch of stock forced downward by the driving-spindle, the spindle driving the staple into the brush-head. While the driving-spindle is descending to accomplish this result the lever 38 is .being actuated to advance the wire and the plunger 22 is descending to cut off the wire of proper length and form the staple. As the lever h ascends the bell-crank 23 is actuated to force the staple upon the forward end of the runway 19, and the various parts which are advanced by the downward stroke of the lever h recede into retracted position, giving opportunity to feed another bunch of stock into the opening o. The plunger 22 is bifurcated at its lower end, and the wire 20 is fed across the rear arm of the runway 19. As the plunger descends the end of the wire is cut off for a sufficient length to form the staple, and the two ends of the severed piece of wire are bent downward over the rear arm of the runway.
