' i To all III/L07 2t may concern:

Be it known that 1, HARRY J. Lnsnnnz, citizen of the United States, Frederick, in the county of l rederickand State of Maryland, have invented certain new and useful Improvements in Brush-Machines, of which the following is a specificallOl].

This invention is particularly, though'not exclusively, designed for use in connection with the brush. making machine set out in Letters Patent of the United States Nos. 578,907 and 664,989, dated March 16, 1897 and January 1, 1901, respectively, to which reference may be had; my object, primarily, being to provide a simple and eilieicnt-construction and organization of mechanism whereby, among other advantages, fibers of variable color, or possessing other different or contrasting characteristics, shall be periodically selected from a source of suppl and applied in the form of tufts to the brush block, as will. be hereinafter described and claimed.

in the drawings igure 1 is a side elevation of a brush machine embodying my inof Fig. 5.

vention in its preferred form, only so much of the machine being shown as is necessary to illustrate theimprovements. Fig. 2 is a similar elevation, as viewed from the opposite side of themachine. Fig. 3 is an elevation, partly in section, showing the plural magazine, the fiber-separating and'carrying slide, the tuft-inserting slide, and adjuncts, the parts being shown in the respective positions which they occupy immediately after the wisp of fiber has been carried to the inserting position. Fig. 3 is a transverse section through the pivoted tuftguide, as on the line 3*3 of Fig. 3. Fig. 3 is a perspective View of said 'uide. zontal' section on. a fiber-separating and carrying slide. Fi 5 is a partial side elevation of the fiber separating and carrying slide, and adjuncts. Fig. 6 is a vertical section, as on the line 6-- 6 Fig. 7 is a'pzirtial elevation of the fiber separating and carrying slide, showing its relativcly-movablc memler as in position to close the mouth of the fiber-gathering and holding opening. 'l ig. 8 is a detail of the movable stop for actuating said member; I' 'ig. 9 is a sectional detail, showing in open position, the devices, and their connections,

for holding and compressing the wisp of fiber residing at I l 'ig. 4 isa hori-' plane slightly above the.

l l l ,fiber magazine; 6 is the horizontallyreciproeating slide, by means of which quantities of fiber are successively se arated from the mass in the magazine, ant fed into position for insertion as tufts into the blocks, and 7 is the vcrtically-reciprocating slide which acts to seat the/fiber successively in the bored block.

8 is a horizontal shaft which is driven from the drive shaft by means of a belt 9 passing y around pulleys 10, 11 on the respective shafts.

The shaft 8 bears a crank arm 12 which is connected through a rock-lever 13 and links 14 withthe slide 7 to effect the vertical action of the latter; and this shaft also bears a cam 12 which is connected by means of a lever 16 andlinkl] with the drill to effect its vertical operation.

18 is a lower horizontal shaft which is driven ste by step through suitable'devices actuatedrom the upper shaft 8. The deviccs herein illustrated comprise an eccentric 19 on shaft 8, and an eccentric rod 20 connecting the same with a rock-arm 2]. bearing a pawl 22 that engages a ratchet wheel 23 on the shaft 18. This shaft 18' carries the cams 24 which, through suitable connections, effect-the requisite transverse, vertical and longitudinal movements of the work-holding table 3 in order to position the brush blocks with respect to the boring and tuftinserting devices.

25 is a horizontal shaft which is driven from the main shaft by a belt 26 passing around pulleys 27, 28, on the respective shafts, and which shaft 25 is belted with a pulley on the spindle of the boring tool.

The several parts above indicated are, excepting as hereinafter particularly described, substantially similar in cxmstruction and operation with the corresponding parts set out in the Letters Patent aforesaid.

R eferring to the magazine, it is to be noted that in pursuance of my present invention, it is divided into two separate compartments,

snreof the spring.

quirements of the brush under construction may demand. This slide in its preferred form includes a long blade or bar composed of two sections joined endwise by a laterally-disposed connecting piece, the opposing ends of the sections being spaced and formed to provide a vertical notch having an overhanging lip 32 which is designed, as the slide is moved forward beneath the magazine, to enga 'e a quantity of the overlying fibers and to orce it down into the notch. On the outer side of this bar, in advance of the notch, is slidingly mounted a plate 33 which is provided with a forwardlyextending lip 34 adapted to close over and confine the fiber within the notch when the plate is moved relatively to the bar. This plate is secured to one side of a block 35 which is slidingly fitted to a longitudinal slot in the bar, anda piece 36 is secured to the o posits side of the block to prevent lateral d splacement of the parts. (See Fig. 6.) This piece is rovided with an angular projection 31 no is adapted to co-act at'prescribed int als with certain steps to effect the lon gitndinal movement of the plate 33 relative to the bar, as will hereinafter appear.

Through the bar 30 is formed an o )ening to permit the downward passage of t e tuft and its inserting devices. livoted to one end of the bar is a link 38 which is connected through a spring-controlled frame 39 with a lever 40 in engagement with a cam 12 on the shaft 8, whereby the slide is longitudinally reciproeated to move its notch or fiber-receiving portion beneath the magazine and the tuft-inserting idcvices alternately. The

- frame 39 is slidingly mounted on the link 38 and is held normally in retracted position thereon by means of a suitably-disposed spring 40, whereby the slide may be moved ndependcntly of the cam against the pres- (See Fig. 3.)

The plate 33 is automatically actuated during the reciprocations of the slide to open or close the mouth of the fiber-receiving notch at predetermined intervals in a man- 'to permit the notch to receive and deliver the fibers from either compartment of the magazine, as desired. The rear end of plate is engaged by the free end of a s ring-arm 41 which is aflixed to the bar 30,

' contacting parts of the plate and arm being so formed that the plate is temporarily contents of the compartment 1), it is necessary to interrupt the supply of fiber from the com artment a, to the slide. A good means for t is purpose comprises a channeled piece 42 that embraces the top of the feed bar and its plate, and is adapted to be moved beneath and from the bottom of the first compartment a. at predetermined intervals. The 'iece42 is carried by an arm 43 extending rom one end of a shaft 44 which is slidingly supported in arms 45 on the machine frame. Extending from the shaft 44 is an arm 46 which is connected by means of a link 47 with the longer arm of a bell crank lever 48, the shorter arm of which bears upon a eripheral cam 49 on the driven shaft 18. 'lhe lever 48 is held'normally in engagement with the cam by the action ofa spring 50 which is secured to the link 47 and to the main frame. (See Fig. 2.)

The contour of the cam is such that at prescribed intervals the lever is raised and lowered to effect the periodical reciprocations of the slide shaft 44 and thus move the cut-off device beneath and from the first compartment (1. of the magazine.

Vhen the lever is riding upon the lower surfaces of the cam the cut-off device is in retractcd position so as to permit the fiber 1n the first compartment (a) of the magazine to rest upon the top of the slide bar, and hence when the notched portion of the latter passes beneath such com artment it separates a quantity of the fiber from the overlying mass. It is necessary that in this stroke of the slide the'mouth of the notch should be closed immediately after it has received the fiber, and for that purpose there is provided in the path of the projection 37 a stop or abutment 51 therefor. The motion of the plate is arrested by the action of'the stop against the projection, while the motion of the. bar continues, and "in conseruence the parts are caused to assume their closed'position, as indicated in Fig. '7. The spring latch 41 engages the outer end of the plate and locks it in closed position, By virtue of the spring-frame connection between the link 38 and lever 40, relative movement ofthcsc parts is permitted when the plate has been caused to assume the closin osition by the action of the stop 51. The quantity of fibc" thus separated and held by the slide is carried to position beneath the tuft forming and inserting devices. As the notch ampproachcs this position, the )rojcction 37 abuts against a fixed stop 37 igs, 4 and 5) which, effects rearward movement of the plate relatively to the bar, and thus uncovers the notch and unclamps the confined fiber.

The stop 51 is conveniently formed on the arm of a lever 52 which is pivoted to a main frame adjacent the magazine, and is held normally in active position by a suitably-disposed s )ring 54 seated in a socket in the bracket. The lever 52 is provided with a shoulder 55 which lies in the path of an arm 56 on the slide-slntft 44, whereby when the latter is shifted endwisc agazine, the arm impinges against the said shoulder and thereby raises the stop above the path cf theslide projection. (Sec Figs. 4-, 5 and 8.) On the bracket 53 in the path of r I stop 57, which is so arranger that when the notched portion'ol' the shdc has passed under the second compart-mentand received fiber therefrom, the proy'ection abuts against such. fixed stop and 1s tiercby caused, by the movemcnt of the plate relative to the bar, to close the notch and confine the fiber thercin. In the reverse stroke of the slide, such fiber is carried thereby to position for insertion in the brush block. So long as the lcvcr 48 is maintained in elevated position by the cam, the slide continues to select and withdraw the fiber from the second compartment of the magazine. Thus, it will be seen that by varying the peripheral contour of the cam, the fibers may be selected from the respective magazines in any prescribed ordcr'so as to produce on the fibrous face of the brushes, vari ous Ipatterns or de igns.

'l re vertically-acting tuft-inserting slide 7 hcreinbefore. rcfcrrcd'to, and particularly described in Patent No. 578,907 aforesaid, affords a guide for the staple and staple-inserting dcviccs whereby I the tuft is fastened in the'brush block.

'lhis movable member preferably comprises an arm carried by a rock shaft (31 having its hearings in the bracket 5.) and also in a chine. ()n the end 0 the shaft (51 adjacent the bracket (S12 is an arm 6.; which is conncctcd by means of a link 64 with an arm 5 carried by a lower rock-shaft so. This latter shaft is mounted in brackets (37 depending from the main frame. To the'arin. (55 is pivotally connected the lower end of a "Cl? tical rod 68, which is held yieldingly depressed by means of a spring 69 secured thcrcfto and to the mainframe. (See Fig. 2.) 'lhus the movable member is held down in yielding contact with the wisp of fiber by the pressure of the spring. The uppcrcnd of the rod (38 has a pin and slot connection 7() with the forward arm oil the rock-lever 13 previously described, whereby when such arm is elevated during the ascent of tho tuftinserting slidc the rod 68 is raised'thcrcwith in a manner to swing upward the movable fiber holding member (it). The pin and slot conncction affords sufficient lost motion between the rod and-lever arm to insure the timely operation of the connected parts.
