BRUSH-f-MCHINE.

SPECIFICATION forming part of Letters Patent No. 696,761, dated April. 1, 1902.

Application filed Tune 22, 1900.

To @ZZ whom, it may concern:

Beit known that I, HERMAN M. SCHWARTZ,

a citizen of the United States, residing at Northampton, in the county of Hampshire, State of Massachusetts, have invented a certain new and useful Improvement in Brush- Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

In the manufacture of brushes of certain kinds-such, for example, as hair-brushesa bristle block or bristle -die is employed. This block or die is usually made of metal and is provided with a series of holes or apertures corresponding in size and relative location with the tufts of bristles in the brush which it is desired to make.

The object of my present invention is toV provide a simple, durable, and efficient brushzo machine for lling the bristle blocks or dies employed in brush manufacturewith bristles.

My invention is fully set forth in the following description, reference being had to the accompanying drawings, and the novel features thereof are pointed out and clearlyldefined in the claims at the close of this speciiication.

In the drawings, Figure 1 is a side elevation of a machine embodying my invention,

3o the bristle-hopper being partly broken away. Fig. 2 is a similar view from the opposite side of the machine. Fig. 3 is a front elevation. Fig. 4 is a plan view of the bristle-block-supporting device, showing the means employed for causing the said support -to be reciprocated horizontally. Fig. 5 is a sectional View of the bristle-hopper, two bristle-blocks beneath the same, and the support for the said bristle-blocks. Fig. 6 is a viewin section on 4o line 6 o', Fig. 1.

The frame of the machine consists of four uprights 1, 2, 3, and et, the uprights 1 and2 being at oneend of the machine and the uprights 3 and 4 at the opposite end. The uprights at each end are inclined toward each other at their upper ends, forming an A- shaped frame at each end of the machine. The uprights are also strengthened and stiened by tie-pieces 5. The precise form and 5o construction ofthe frame is, however, not

Serial No. 21,189. (No model.)

material. At the top of each pair of uprights is a cross-piece 6. The main shaft 7 is supported in suitable journals on the said crosspiece 6. On the said shaft 7 are the usual fast and loose pulleys 8 and 9, which are employed in driving the said shaft. Toward each end of the shaft 7, and preferably inside the uprights of the frame, I secure a cam- Wheel 10, having on the face thereof a cam 100, With which a pin 12 engages, the said pin being secured in and projectinglaterally from the upper end of the connecting-rod 13. The lower end of the said connecting-rod is secured to the end of the bristle-hopper 14E. The connecting-rod 13 passes through a lug or projection l5, secured to one of the crosspieces 5 of the frame, and below said crosspiece is provided with a collar 16, firmly secured thereon. Between the lug 15 and collar 16 is placed a spiral spring 17, which as the rod 13 moves upwardlyis compressed and tends to moves the rod downwardly. The cam formed in the face of the Wheel 10 is of the shape shown, Figs. 1 and 2, and operates when the wheel revolves to cause a vertical vibration or reciprocation of the bristle-hopper 14. As the Wheel rotates the pin 12 will be caused to roll or slip from one of the points 11 lof the cam to another, thus raising and lowering the connecting-rod 13 and bristie-hopper 11i four times during each revolution of the Wheel 10. This results in a very rapid reciprocation through a short range of movement, which is desirable. This means `for supporting and reciprocating the bristlehopper is duplicated at the opposite end of the machine, as will be clear. The bottom of the bristle-hopper is reticulated and is formed,

preferably, of Wire-netting 1S. The bristles are placed in the bristle-hopper and are caused by the reciprocation thereof to pass downwardly through the reticulated bottom andv into the bristle apertures or holes 19 in `the bristle-blocks, one of which is shown at20, as will be hereinafter more fully set forth. f

For the purpose of properly agitating and separating the bristles in the hopper and prei venting them from becoming matted and massed together I provide an agitator which extends legthwise of the said bristle-hopper and supported on u prights of the frame.

3o more etfectually agitated and separated.

65 in the other direction.

and comprises a rod 2l, having a series of outl one diagonal position to the opposite, While wardly-extending teeth or pins 22 thereon. This agitator is journaled in cross-pieces 23 and 24,located at opposite ends of the machine The shaft or rod 21 of the agitator extends through horizontal slots 25 and 26, formed at opposite ends of the said hopper, the said slots being greater in width than the diameter of shaft ro 2l, thereby providing for independent vertical play or movement of the hopper to a slight extent. To one end of the said rod or shaft a pulley 27 is secured, to which power is communicated from the main shaft 7 by means 15 of the pulley 28 on said main shaft and the connecting-belt29. By this means the agitator-shaft iscaused to rotate,forcin g the teeth 22 through the mass of bristles in the hopper and operating to separate and agitate them.

zo In addition to its rotary movement, however,

z5 of a position parallel with the sides thereof,

and will then move horizontally, its opposite ends moving in opposite directions until it assumes the opposite diagonal position. In this way the entire contents of the hopper are To give the agitator this swinging or vibratory movement simultaneously with its rotary movement,the cross-pieces 23 and 24, in which the shaft 2l of the agitator is journaled, are

caused to reciprocate horizontally by the following mechanism: At one end of the main shaft 7, outsidethe uprights 3 and 4, I secure a pulley 30. A shaft 3l is journaled in the uprights 1 and 4 at a somewhat higher level 4o than the top of the hopper 14. Outside the uprights 4, on the end of the shaft 31, I secure a'pulley 2, which is connected by means of a belt 33 with the pulley 30 of the main shaft. The shaft 3l is provided at the opposite ends thereof `with cranks 34 39, the pins of which Work in longitudinal slots 341, Fig. 1, in arms 35 and 40, which are pivoted to the uprights 1 and 4, as at 342. The lower ends of the arms 35 40 are provided with longitudinal 5o slots 36, receiving pins 37, provided on the horizontal supports 23 and 24.' The opposite ends of the horizontal supports 23 24 are provided with slots 371, through which pins 38 on the uprights 2 and 3 project. By this arrangement the throw of the cranks 34 39 causes the horizontal supports 23 24 to have a horizontal reciprocating movement.

The agitator-shaft 21 is journaled at one end in the horizontal support 23 and at the 6o opposite end in the horizontal support 24, and

the cranks 34 and 39 are set on opposite phases, so that as the horizontal support 23 moves in one direction the horizontal support 24 at the other side of the machine moves This causes the agitator-shaft 2l to. assume vdiagonal positions within the bristle-hopper 14 and to move from at the same time it is given a rotary movement, and thus the teeth or pins 22 on the agitator are caused to engage the entire mass of bristles within the hopper and to so act upon the said mass of bristles as to separate the mass and prevent it from matting or massing together.

Directly underneath the hopper 14 and suitably supported on the frame I place a frame comprising end pieces 4l 4l and bars 42,which extend between said end pieces and are secured thereto. The said bars form a support for the bristle blocks or dies and at the same timepermit anyloose or surplus bristles which do not enter the holes in the dies or which are brushed off the dies by the operator to fall between the bars 42 into the receptacle 43 below the latter. In the operation of filling the bristle-blocks they are placed directly beneath the hopper 14, and I have found it desirable to slowly move the said bristle-blocks laterallyin the operation of iilling them. One of the advantages of thus moving the bristleblocks while they are being filled results from the fact that since the bottom of the hopper is formed from wires some of the wires may be located directly over some of the bristle holes or receptacles in the bristle-blocks, and will thus to some extent interfere with the proper and speedy iilling of the hole or receptacle with the bristles. By moving the die-blocks laterally or diagonally the said holes will be uncovered and all of the bristle receptacles or holes in the bristle-blocks Will be quickly and evenly filled. To this end I place the bristle-blocks on 'a horizontally-reciprocating portion of the barred support, said reciprocating portion being directly underneath the hopper. This portion of the support consists ot' a frame comprising end pieces 44 44 and a series of connecting-bars 45, secured at either end to said end pieces 44. 'Each of the end pieces 44 is provided with a projecting guide or support 46, which passes through an opening in the proximate end pieces 41 and serves to support thereciprocating frame, upon which the bristleblocks are placed while being filled. The said reciprocating frame has preferably a slow reciprocating movement between the end pieces 4l, the extent of its reciprocation being comparatively slight. For the purpose of causing reciprocation ofv the said frame I provide one of the projections 4b' with a link 47, which is pivoted at 49 to the face of a ratchet-wheel 48. The said wheel48-is mounted upon a suitable arbor carried bya bracket 48a, Fig. 2, and is actuated by means of 'a bent lever 50, having a tooth 5l, whichengages with the teeth of the ratchet 4S. The lever 50 is pivoted to a cross-piece 52, extending between the uprights 3 and 4, and its upper end projects over and is in proximity to the face of the pulley 32. On the face of the said pulley 32 I secure a projection or tappet 53, which as the pulley 32 revolves acts against IOO IIO

one side of the lever 50, moving the said end away from the faceof the upper end of the pulley, causing the lower end of the said lever to move in the opposite direction and to rotate the ratchet 4S the space of one tooth.

The upper end of the lever 50 is held by" means of a suitable spring against the face of the pulley 32, so that after the projection 53 has passed the end of the said lever 50 the said end will be snapped back against the face of the pulley, throwing the lower end of the said lever 50 outwardly over the next tooth in the ratchet 4S in position to again move the ratchet the space of one tooth at the next revolution of the pulley 32. By this means a slow reciprocation of the barred frame, upon which the bristle-blocks are supported while being lled, is effected.`

The receptacle 43 is provided, as above described, for the purpose of catching the surplus bristles which failto get properly into the bristle holes or receptacles in the bristleblocks. The said receptacle 43 has an inclined bottom 55 extending from the front of the machine rearwardly and downwardly to a point at the rear of the bristle-hopper. The rear wall of this receptacle is shown at 56. As the bristles fall into the receptacle 43 they slide downwardly and rearwardly toward the lowest position thereof and are then carried upward by a toothed conveyer 57, which re-` turns them to the bristle-hopper 14. This conveyer is actuated by the shaft 3l, previously described, and consists of asheet of smooth flexible material secured at its opposite edges to a belt formed of material suitableto engage the guide-rolls overwhich it passes. The conveyer passes over the shaft 3l, thence downwardly and rearwardly over the guide-rolls 58, located at and engaging with the edges of the conveyer,t'he'nce outwardly and forwardly around the shaft or roll 59, near the deepest part of the receptacle 43, thence uparound the guide-roll 60. The conveyer is provided with transverse rows of curved fingers 62. The fingers 62 pass downwardly into the mass of bristles in the deepest portion of the receptacle 43 and then pass upwardly, carrying a portion of the bristles with them, and as they pass over the shaft 3l, above the rear edge of the hopperl4, the bristles carried upwardly from the receptacle 43 would be discharged into the hopper.

The machine lls the bristleblocks evenly and quickly and is automatic inits operation. The operator requires only to place the empty bristle-blocks in position underneath the hopper, withdrawthem after they have been filled, and brush off the extra or surplus bristles.
