1 all whom it may concern Be it known that I, ANTHONY VANonnmm, a citizen of the United States, and resident of Grand Rapids, in the county of Kent and State of Michigan, have, invented certain new and usefnla Improvements in Brush-Making Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

i r ection as Fig. 2. Fig. 4 is an elevation of vi Fig. I.

My invention relates to improvementsin brush making machines and its object is to provide a machine of the class shown in my (co-pending application Serial No. 741,834, filed Jan. 13, 1913., with automatic means for adjusting a brush blank step by step in the various positions necessary to insert tufts of bristles, to automatically stop the machine at a predetermined point in its operation, and to provide the same with vari ous new and useful. features hereinafter more fully described and particularly pointed out in the claims.

the same as in theco-pending application,

The driving shaft 1 of the machine carries a driving pulley 2 loosely thereon which is engaged by a driving friction clutch '3 to connect the same to the shaft upon operation by bell crank mechanism 4, which is connected by a'rod 7 to an arm 6 on therocker shaft 5, this shaft being providedwith' a lever 9 which may be operated to thereby hold-the clutch, in engagfment with the ul-- ley to operate the mac ine.- .On the riving shaft are located cams 13, 14 and 15 which operate, respectively, the staple guide,

'the' staple driver and the drill arm.

counter shaft 12 at rightangles to the driving shaft 1 is connected thereto by miter gears 12 and .is driven by means of-such connection. Cams 16, I7- and18 are located on the counter shaft and operate, respectively, the drill arm in'its horizontal movement, the bristle feed Wheel by'means of the reci-procable rod 21, and the staple forming mechanism. I have also shown in this ap-.;. I

plicationfa pulley'99 for-driving the drill,

a staple guide 9.4,two superposedbristle' beds and39 pivoted in brackets 88, the bristle feed wheel 87, the air pump 100,the di'es'98, the transfer finger 93, the fastener 89, the feed rollers -91and operating plication previously referred to.

To automatically-stop the machine, I proarm (3, which when the lever 9 is released will cause the clutch 3 to be thrown out of engagement with the pulley 2, thereby automatically disconnecting the power'and stopping the machine. .When the machine is running, the lever 9 is held in. position to ('n gage the clutch with the driving pulley ride a contractile spring S'connect'edto the by means of a. latch or hook 10, best shown" in Fig. 5, which hook may at any time be manually released through the liandle 11.: l

The hook is normally heldiirmly in-engagement with lever 9 by a spring 11.

As a means to automaticallyv release the lever f) and-stop the machine, I have provided a push rod 29 pivoted at one end to the vertical member 22 of a bell crank lever, which is pivoted on a stud 60, the horizontal member 22 of this lever being connected by rod 20 to an eccentric 19 on the counter shaft .12, the lever through such connection being oscillated at each cycle of the machine. Rod 29 is slidably supported adapted to engage the end of the lever and raise the same, thereby lowering the other 'end of lever 30 suflici'ently that push rod 29 may engage the latch 10 and raise the same, releasing lever 9 and through it the clutch, and stopping the machine. Cam

drum 65 is rotated step by step by means of a pawl 24 mounted on an arm 23 extending from the bell crank 22 and oscillating therewith. Pawl 24 extends in opposite directions from its pivot and at the end opposite. the drum engaging end it is pivotally attached to a rod 26, at one end thereof, the other end being provided with a pin 27 slidable in a recess 28 in the side of lever 22. A spring 25 interposed between members 22 and 26 serves to hold the pin always in contact with member 22.

As a means of limiting the movement of the'drum ,65 to the last. part of the movement of the pawl 24, whereby the drum is shifted in proper time, the stroke of the pawl being greater than the spacing of the ratchet 65 on the drum, the pawl is lifted to go clear of all but one of the ratchet teeth by means of an inclined wedge 27 which engages the in 27 and depresses it during a portion. 0 the movement of the pawl,

' raising the pawl clear of the teeth traversed thereby, while the pin is in contact with the incline. a

' In the drum 65 are numerous holes 73 arranged spirally therein to providea sutli cientnumber to correspond to the number of tufts of bristles to be inserted-in the brush blank. The drumis, mounted on a longitudinallymovable shaft 64, which rotates therewith, and a worm 67 having a pitch corresponding to the spiral arrangement of the rows of holes in the drum is fixed in the frame of the machine and loosely mounted on the shaft 64. A pawl 68 is fixed on the shaft 64 and rotates therewith, and it traverses this worm, movingthe shaft longitudinally and with it the drum whereby the spirally arranged row of holes will pass under a given point as the drum rotates. Pawl 68 is yieldingly held. in engagement with the worm by a spring, and is provided with a lever-69 having pivotal attachment with respect to the shaft. 64 allowing the pawl 68 to be disengaged from the as for instance in putting in alternate rows of white and black bristles, or an outer margin of one kind and an inner portion of another kind, a pin 38 is inserted in the side of the bristle beds and en aged by an arm 37 on a rock shaft 36. 'lhe brackets 88 are pivoted nearest to this end of the beds and the end of the beds next to the feed wheel 87 normally drops to a position adapted to feed bristles from the upper bed. Whenever tufts are to be fed from the lower bed, screws 74 are inserted in suitable holes 73 corresponding to these tufts when the machine operates, and each of these screws engages one arm 35 of a bell crank lever and raises the same, the other arm of which projects upward and supports a hook 31 having a shoulder 31 adapted to engage a projection on an arm 32 on the rock shaft 36. \Vhenever the arm 33 is moved from under hook 31 by reason of one of the screws 74, the shoulder 31 will engage and move the lever 32 and depress the rear end of the bristle beds and raise the end of the bristles into the feed wheel 87.

arrangement any number of tufts in any part of the blank can be fed from the lower bed by inserting screws in the proper holes in the drum corresponding to the desired openings in the blank to be supplied with tufts of bristle? The brush blank 40 is securely clamped to a bed plate 41 mounted on a frame 42 vertically slidable on a bar -13 pivoted at 44 on a horizontal axis and swinging within a yoke 45 journaled in bearings 46 to turn on a horizontal axis at right angles to the axis 44. The bed accordingly has an oscillating movement about two horizontal axes at right angles to each other, and also a vertical movement. The oscillating movement about the axis H-is effected by means of a rod 50 longitudinally slidable in the axis l? of the yoke 45 and attached to the rocker bar by a connecting-rod 51. This slidable rod 50 is provided at its outer end with a grooved'eollar 52 engaged by a bell crank lever 53 operated by'a rod 55 connected to the same and extendingdownward the lower end thereof inine the position of the frame 42, it is lessees 7 provided at its lower end with 22 supporting rnit the com drum to be returned to starting position, the arms 56 end 57ers prolonged oppositely from the stud59 end engaged by e litti g; cam 61 mounted on e rotating shaft 62, the opposite end of which is provided with a manually operated crenk 63. -And to properly locetethe drum for starting position, e stop 78 is provided consisting of a. rod sliclebly mounted in a side of the frame of the machine, and normally drown inwsrdly under the influence of spring 79 so that collar 80 mounted on the rod contacts against the side of the frame, such rod, how

such position that the drnn'i is placed in proper starting position. To automatically return the drum, n. splrel spring 66 stir-- rounds the shaft or and engages s'coller 86, whereby when the pawl 68 is released, the shaft 64 is moved endwise to starting position. To hold the'druin from turning except as moved by the pawl 24. o. friction brnlre 70 is provided which is bifurcated and clemped by a bolt through the some on the hub of the drum and provided with an arm 71 slidably engaging a stop pin 72, The drum can turn only against the friction of the brake and accordingly is not open to accidental movement except under extraordinnry circumstances. Yoke 45 is iournaled on a vertically movable frame Sl sdjnsted by it screw 82, provided with e'hand wheel 83 geared thereto.

The form 5 is carried on a slide 8 lverti- I .cally adjustable on the frame 81 and adjusted by a screw provided with who-11d wheel 86. v

The ca-m drum 65 is provided with holes 73 corresponding in number to the number of tufts to be setin the brush to be made on the machine. Screws 74- or equivalent projccting niei'nbers are inserted in as inany'of these holes as correspond to the tufts required to be set in bristles from the lower bed. In e. hole counting from thcfirst or starting hole, corres )ondin'g to the next after the last tuft to e set, {i stop pin 75 is inserted which operates to stop the inz chine when the work 1S completed. Suitably drum niny bezmovcd bodily to-.

During short thenext corresponding operation, the pswl 24c shifts the coin drum one notch of the ratchet, which movement" shifts the brush blank to proper position for the next tuft of bristles, the blank beingmoved about through the levers 57 and 5-7 the rod 58 end arm 59, endshifting the blenlt properly to space apart the tufts in the respectiverows; and, at the end of each rowthe corn '7! slides the shaft 50 longitudinally snlliciently to ll to pro-perlyspace apart the respective wows ct bristles. It will be noted-that in Fig. 2 there are points in the cam 77 where an abrupt change inthe surface of the coin is shown, these changes being of smell dothat, the shifting of the blank to set another row of bristles occurs; and at'thc abrupt drop of considerable degree shown, the brush is finished, and the blanlt'encl holder swung over to the original or starting row. In the meantime the form 54- supports the blank in proper elevation to determine the depth at which the bristles are to be inserted in the blank. By changing the outline of said cams and form, the machine may be utilized to. make various forms of brushes.
