Fig. 3G is a detail in vertical section of a portion of the wire feeding mechanism. Fig. 37 is a front elevation of the bristle feed wheel and the parts co-acting therewith.

Throughout the several views, like reference numerals refer to like parts.

The driving shaft 1 of the machine carries a driving pulley 2 loosely thereon which is engaged by the same to the driving shaft upon operation of a bell crank 3 connected by suitable mechanism to treadle 3", whereby the machine will operate as long as the treadle is depressed but will stop when it is released. A counter shaft 4 at right angles to driving shaft 1 is connected to and operated by the driving shaft by means of miter gears 5. number of cams are located on the driving shaft, cam 6 operating the drill armin a vertical plane, cam 7 operating the staple driver, andcam 8 the staple guide. ,

Cams

9, 10 and 11 located on the countershaft 4 operate respectively, the drill lever laterally, the bristle feed mechanism, and the fastener forming and placing mechanism.

The brush blank is adjusted and held in the following manner. The bed plate 24 has a central stud or proj upper surface. Any convenient number of platens 26 are provided according to the the driving clutch 3 to connect.

ection 25 in lts at the top,

able in the frame 46 and erated by gears 62' driven different styles and sizes of brushes to be made on the machine, one only being shown in the drawings, and each platen is provided with an end and a side rib 27 on its upper surface against which the brush blank 126 is securely held by a cam clamp 28. site the blank, the platen is provided 011 the .under side with a plurality of recesses 29 each adapted to receive the pin 25, said recesses being directly beneath the places in the brush blank where the dilferent tufts of bristles are to be inserted. Semi-circular brackets 30 support the bed and have segmental tongue and groove engagement with the head 31, the axis of the same being above the plane of the bed and held in adjustment thereon by a bolt 32, which firmly clamps the head between the brackets and thus provides a rigid and substantial support for the bed. This head is mounted on a downwardly projecting stem- 41 vertically movable in a socket 34'and having a T-head 33 this socket being vertically movheld firmly from rotation by a spline 34, which frame is vertically adjustable in ways 47 by means of a screw 48, operated by a shaft 49, connected thereto by gears 50, and manually rotated by a wheel 51 to raise and lower the frame,

thereby providing for brush blanks of varying thickness, and allowing a blank to be quickly and easily placed in position. I

Socket 34 is yieldingly supported upon a spring 44 which is adjustable for tension by a screw 45, and to limit the upward movement of the socket, it is provided with a headed stud 42 vertically movable in a cap 43 fixed on the frame and against which cap the head of the stud is forced by the spring. To tilt the table 24 step by step as occasion may require, segmental su orts 35 are pivoted at one end to the T- liead 33, and

adjust-ably supported at the other end by a bolt 38. These segments are each provided with a series of recesses in its upper side, ends of the beds by followers 76, which are and arms 36 on the brackets 30 are provided with rollers 37 which engage these recessesstep by step and support the table 24 at different angles. To revent the head 31 from rotating in the soc et 34, an arm 39 is provided having a downwardly projecting pin 40 slidable in an opening in the head 33.

A rotating drill 52 is carried on the outer end of an arm 53. This arm 53 is mounted on a universal joint bein vertical axis near the mid le upon a support 54 which in turn is pivoted on a horizontal axis 55. The drill is driven by a belt 59 running around

idlers

60 and 61, thence upward to a driving pulley 62 opfrom the counter shaft 4 in any convenient manner (not shown).

To move the drill to operative position while boring the blank, and then move it pivoted on a out of the way while the other mechanism is inserting and securing the bristles, the arm 53 is held in operative posit-ion by a spring 58 and operated about its vertical axis by a push pin 57 which engages the arm 53 at one end and at the other end is engaged by a pivoted lever 15 having a roller 15 that is engaged by cam 9, whereby the arm is alternately allowed to move to operative position, and swung horizontally on its vertical pivot away from operative position.

To feed the drill vertically into the blank and to remove the same after drilling a hole therein, the arm is swung upon the horizontal axis 55. In the position indicated in full lines in Fig. 30, the drill may drill the hole in the blank, and the dotted line position indicates the position taken when the drill is removed from the work. The vertical movement of the arm 53 is accomplished by a lever 14 having a roller 14 that engages a groove in cam 6, said lever being connected to the inner end of the arm 53 by a rod 56, which rod is connected by a universal joint 63 to the lever 14 thus permitting the horizontal movement of arm 53 about its vertical pivot as well as the vertical movement about horizontal pivot 55.

I prefer to provide for placing two grades of bristles for which purpose, I have shown two superposed bristle beds or

ways

20 and 20*, pivoted upon brackets 21, to alternately shift to opposite the feed wheel at the discharge end of the bristle beds. These beds are provided with ribs 75 enabling the bristles to slide easily toward the feed wheel and to properly enter the slot therein, as hereafter described, and at each end of the bristles are parallel plates-74 adjustable toward and from each other to conform to the various lengths of bristles as occasion may require in making different brushes, and properly adjust them in the wheel and guide. The bristles are forced toward the discharge placed behind the bristles and which are oplowers by the cords 77, the cords being extended over and guided by pulleys 78 as shown. Opposite the discharge end of the beds is a feed wheel 70 having a radial slot 72 in its periphery to receive the bristles,

the quantity received being determined bv anadjustable stop 73 inthe slot. Wheel 70 ismounted on a shaft 64 and is rotated a i half a revolution and back again at each cycle of the machine by means of a longitudinally movable rod 16 having a link 16 surrounding the counter shaft 4 and vertically movable thereon. This rod is moved by rollers 17 thereon engaging the cam 10.

-The lower end of this rod is provided with a rack 65 which engages a pinion 65 loose on the shaft 64. Fixed on this pinion are arms erated by weights 79 connected to the fol fill 66 and 66' spaced apart and in one"of,whicli is an adjustable screw 67." An arm"68 is fixed on the shaft 64 and extends between the arms 66 and 06'; By this connection the rotary movement of the wheel 70 maybe exactly adjusted'by adjusting the clearance between the screw 07 and the arm 06 which screw and arm alternately engage tie arm 68 and rotate the shaft 6-1 in opposite directions as the rack is reciprocated by the cam 10.

To retain the bristles in the slot 72 as the wheel rotates, a' hood is provided above the wheel, and to shift the bristle bed with either the upper or lower portion 0 ositc the feed whee a manually operated s ufting lever 28 is provided and connected to the bet by a rod 22, pivoted to the bed at one end and eccentrically ivoted to the lever 23 at the other end, wiereby turning the lever half a revolution, raises or lowers the bed. The hood 80 prevents the escape of the bristies from the upper bed when the lower bed is feeding, and when the up er bed is feeding, the bristles are held in tto lower bed by steps 71 attached to an arm 09, which arm is also provided with a bearin 69' for the shaft 0 To receive the tuft o bristles thus formed in the slot of the feed wheel, a staple guide 81 is provided having a lateral opening adjacent t 0 wheel 70 and a pro'ecting incline 82 beneath said opening anti extending alongsidethe wheel to remove the bristles from the slot therein and guide the same intoa transverse openin 83 in the guide. This guide'is also provu ed with'an upwardly extended opening 84 to receive the fastener or staple as hereafter described,- and also with a discharge openin 112 at the lower end through which the ristles are driven in the'operation of setting the same. This guide periodically moves up and down bcin lowered in contact with the brush blan c during the operation of inserting the tuft therein, and vertically moved to permit the blank to be shifted and to receive the tuft and fastener and to permit the drill to operate, b means of the lever 12, provided with a rot or traversing a groove in the cum 8, and having a slide 110' at its opposite end engaging a way 110 attached to the staple guide 81. In this guide is a staple driver 113 attached to a side 114 independently movable in the guide 81, and provided wit 1 a pin'llti having a block thereon slidahle in a slot in the lever 13, which lever is operated by the cum 7 having a cam groove to receive the roller 13 onthelever.

The fasteners for holding the bristles in place are formed from a. continuous strip of metal or flat wire 80 fedforward by means of the feed rollers 87 oppositely-oligagln the name, one of which railers n moantot on a lever 09 and pressed toward the other by a spring 08. A ratchet wheel 88 is connected to one of the rollers and engaged by a pawl 89 mounted on an arm 90, noted on the shaft carrying the roller, and lilvlng on its'movable end a roller 91 which is engaged by the cam 11 whereby the lever is per:- odieall moved and shifts the ratchet wheel and r0 lers feeding the strip 08 forward a suillcient distance to supply material for one of the fasteners. One of these fasteners is shown at 127 in Fig. 20, somewhat enlarged, and it consists of a short piece of this metallic stri with a semi-circular recess 127 in the mid dle of one side and acute angular spurs '127" and 127" at its respective ends, formin a recess at each end. The fastener 127 is armed by means of the dies 98 and 09 having opposing acute angles spaced apart, as shown in Fig. 18 in )lan view.

The die 08 has a channel in which the strip 80 slides, and is provided with a round opening, partially within the channel and midway between the dies to receive a punch 04. The die 00 has a curved channel 123 for the escape of the waste material cut. from the stock. Co-act-ing with these dies is a round punch 04 which enters the hole in the die 08 and cuts out the semi-circular recess 19.7. A punch 05 co-acts with both dies to sever the strip at each end of the fastener and form the s urs 127" and 127" at its respective ends. he waste material escapes through

openings

124 and 125. This punch is preferab y round and also provided with grooves 05* at. opposite sides to receive the angles of the dies. Above the dies are ctfitps 100 to hold the material from rising o the (lies. Beneath the dies and contacting'the same is a se mental bed plate 107 between which and tie concave under surface of the dies is a way 109 concentric with the axis of the oscillating arm 101. On this arm is a finger 102, the end of which traverses in the way 109 and into the. staple guide to a point beneath the staple driver 113. In the staple guide is a continuation 111 of this way to receive the fastener, which continuation when the staple guide is raised, forms a continuation of the way lwtween the bed plate 107 and thedie 00. This carved way and continuation extends through substantially 00 degrees, whereby the fastener turns from horizontal to vertical position, as it is moved from beneath the punches into the guide.

Punches 04 aml 05 are carried by a slide 19 which is rcci irocated by a lever 18 ]novided with a rolicr 18 at. one end traversing a cam groove 11, in the cam 11. At the other end this lcvcr 18 is pivoted to the slide '10, and is mteruualiately mounted on an cccentric pivot. 00 adjustable by a lever 07 whereby'the down stroke at the pant-hes (an be accurately adjusted to carry the fastener downinto the wa 10!).

The rocker 101 is operated by an arm 10a ill) to which is connected a rod 104 at the lower end, the upper end of the rodbeing pivoted to the movubleendofiapivoted arm having a roller 106, which rollentraverses the cam groove 11" in the cam 11. A retaining plate 108 spaced apart from the bed plate 107 by a spacing plate 110 and having its edge engaging the dies permits the tlnger 102 to swat; therebetween and retain the fastener in t 1e way 100.

As a means of removin" the borings and other obstructions, if any, ormedby the drill, a blower is provided having the following construction. Air pump 11? isopera'ted by movement of the guide 81. Leading from the pump is a tube 118 the middle portion 118* being tlexihle to permit the movement of the lower part thereof. This tuhe terminales in a curved rigid nozzle 118" which is carried by an arm 120 on a rock shaft 11$), tttrnin on a vertical axis. and mounted near the Silt e 81, in which shaft is a spiral groove 121 engaged and traversed by a pm 122 tixed in part 110, whereby as the latter reciprocates, the rock shaft is oscillated about its axis, which movement carries the lower end of the nozzle 118 around in contact with the last tuft of bristles set, as shown in Fig. 11. The air escaping the nozzle blows away any borings or obstructions that may be made by operation of the drill. As the slide 81 rises, the nozzle is swung out of the way to permit adjustment of the blank for setting the next tuft, also to allow the drill to o erate.

ith the above description in mind, the operation of the machine is readily understood.

The blank shown in the drawings at 126 is for a tint brush with the bristles positioned vertically therein. In making this form of brush, the bed 24 may be adjusted to horizontal position and vertically ad'usted to conform to the proper thickness of the brush blank, and a ilatcn used having recesses 20 corrospont ing to the number and location of tufts to be-inserttal in the blank. This platen carrvin the blank may then be placed on tho itttr lllltl manually shifted step by step to successively position the pin 2.". in the various recesses 20 as each tuft is successively inserted in the blank.

The first operation is to bore a hole as the cams ti and 0 rotate. Cum 0 first )0!- mits the arm on to swing with't-he drill above the blank, cum 0 then raises the rear of the lever l-l depressing the arm 58 and forcing the drill into the blank the proper depth. Further movement of cum 0 causes the drill torise and when it is out of the blank,.the mm 0 swings the arm carrying the drill horizontally, the drill being thus moved both vertically and laterally and out of the way of other mechanism. In the meantime cam 10 has depressed the rod 10 which rotates the shaft 34 and feed wheel 70 a half revolution from the position shown in ,Fig. 23 to the osition shown in Fig. 22, car ying the brist es which have entered the slot 72 over into the staple guide, as indicated at 85 in I i 22, the ire ine 82 having removed them fi'om the slot 72 into the staple guide in proper )osition to be engaged by the fastener as it descends. Aftet the drill has been moved out. of the way, the staple guide 81 is moved downward by the cam 8 to a point directly over the hole in the blank and close to the surface of the same. In the meantime the downward mm ement of the slide 11), operated by the lever 18 and cam 11, cuts out the fastener by means of the punches 04 and 05 and the dies 08 and 0t),- depositing the fastener in the way 100 beneath these punches. The cam 11 now operates through the rod wt to turn the rocker 101 carrying the finger 102, which latter engages the fastener and carries itv along the way 100 and through the extension 111 of the same in the staple aide, depositing it therein directly above t to tuft of bristles, as indicated in-Fig. 10. As the tinger 102 moves back out of the way, the driver 113 is now moved downward by the cum 7 and lever 13, which driver engages the fastener and carries it together with the tuft of bristles folded over the same down to place in the hole in the blank as indicated in Fig. 21. The driver enga es the upper end of the fastener between tie spurs 127", and the tuft of bristles is folded over the lower end of the fastener between the spurs 127". As the fastener strikes the bottom of the hole in the blank, the recess 127 permits the fastener to yield and fold laterally, which forces two of the smrs opposite the recess against one side of the opening or hole, and the middle of the edge opposite. the recess against the other side of the same, securely anchorin the fastener and tuft in place within the liolo, as shown in Fig. 21. The driver and guide then recede to time, and the operator manually shifts the lJltlllb' to the next position with the projection in the next. recess of the plate in the series, and the machine may then repeat the operation for the next succeeding bristle tuft.

If it should be desired to set any row of bristles inclined to the vertical, the table 24 is tilted upon the head ill by shifting the arms in the recess of the supports tlfi. in the event. of any accidental pvcr prossnre downward by any obstruction or otherwise, the spring 44 will yield, permitting the table to descend and avoid breaking the machine. At each cycle of the machine, the rock shaft 119 is oscillated and the air pump 117 provides a blast of air through the noz- ,zle 118" which clears away any chips or other light. olmtructions that may be In lilo way.
