BRUSH MACHINE.

Application filed lsebruary 19,1925. Serial No. 10,290.

The invention relates to brush machines of that type designed to perform only the tufting operation on previously bored brush backs, and it is the primary object to obtain Y a construction which may be used either for hand filling operation or for automatic filling of brush backs of various sizes and patterns. To this end the invention consists in the means employed for efiecting the suc-v cessive registration of the holes in the back with the tufting nozzle as hereinafter set forth.

In the drawings: Figure 1 is a side elevation of the machine; 1

Figure 2 is an elevation at right angles to Fig. 1;

Figure 3 is a perspective view of the work holder;

Figure 4 is a section on line l of Fig. 5;

Figure 5 is a section on line 555 of Fig. 4:;

Figure 6 is a sectional plan view on line 66 of Fig. 2;

Figure 7 is a cross section on line 7-7 of Fig. 2. I

In general construction the machine comprises a frame or pedestal 1 on the upper portion of which is mounted a tufting unit, including a bristle holding magazine 2, tuft separating needles 3, a reciprocatory tuft setting nozzle 4, wire feeding mechanism 5 and other auxiliary parts for forming the tuft securing staples engaging the same with the tuft and driving. the staple and tuft in a registered holein the brush back. As the unit thus briefly described is the same in general construction as in my previous application Serial No. 527,590, filed January 7, 1922, it is unnecessary to describe the same more in detail. I

The brush backs to be filled with tufts are previously bored in any suitable .ma-

chine, such as a multiple drill which will 6, which may be raised or loweredby the adjustingscrew 7 and clamped in position by the clamping screw 8. Upon this table or shelf is mounted a frame 9, on'the upper end of, which is a horizontally movable frame 10 with ananti-friction support formed by the raceways 11 and ball 12. Upon the frame 10 there is arranged a transversely movable table 13 with an antifriction support formed by the raceways 14.- and balls 15. Thus the table iscapable of movement in one direction on the frame 10 and together with said frame is movable in a transversedirection on the frame 9. Beneath the frame 10 there is journaled in the frame 9 the vertical shaft 16 adapted to receive at its upper end the cams 17 and 18, which are keyed thereto and secured by the cap screw 19. Theshaft 16 is driven through the medium of bevel gears 20, 21,

' from a shaft 22, which extends to one side gagement with a bevel gear wheel 32 journaled ina bearing 33 on the frame 9. There is also a yoke connection 34 between the shafts 25 and 31 by which these shafts and the gears 29 and 30 will travel together in the adjustment of the plate 26,-this being permitted without moving the bevel gear 32 by reason of the spline engagement. The bevel gear 32 is driven by the bevel pinion 35 on a vertical shaft 36, which in turn is driven through the bevel gear wheels 37 and 38 from the shaft 39 of the tuftsetting unit. This shaft is driven through the pulley 40 from any suitable source of power.

The shaft '36 is preferably made in two 7 parts 36 and 36 which are normally:

, The train of mechanism just described 3 will transmit rotary motion from the shaft 39 to the shaft 16 and from the latter to the cams 17 and 18'mounted thereon. The cam 18 is in engagement with a bearing finger 41 upon the frame 10 so as to transmit movement to said frame yieldably re-- sisted by the spring 42, while a finger 43 depending from the table 13 engagesthe cam 17 and is actuated thereby against the yieldable resistance of the spring 44. The

spring 42 has one end thereof attached to the slidable frame 10 as indicated at 42,

ing said cams,

Any suitable work holder may be mounted uponthe table 13 to secure the brush backs which are to be operated upon. Preferably this work holder comprises a slide 45 mounted in gu'ideways 46 on the table and mov able between stops into two different positions. As shown, the stops are shoulders 45 at the ends of a recess 45 inthe underside of the slide 45. A pin 46 projects into this recess and is adapted to alternatively engage the shoulders 45.

On the slide is a pair of work holding clamps 47 .in which the brush backs, such for instance as tooth brush handles, may be inserted. These clamps may be properly registered with the tuftin-g mechanism by moving the slide to its opposite limits, so that during the time of'the tufting of the back in one of the clamps the work may be removed and re.- placed in the other clamp.

The machine is started by the throwing in of a clutch 48 controlled by the trip rod 49 actuated by the pedal lever 50 and the stopping of the machine is effected by a lever i 51' actuated by a pin 52 on the cam 18. The

lever 51 normally operates as a latch for holding therod 49 in depressed position against'the tension of a returning spring 53, but the movement of said lever under actuation of the pin 52 disengages this latch and permits the rod 49 to disengage the clutch 48, thereby stopping the machine.

In operation, to tuft a brush back of any desired pattern, the proper cams are selected and engaged with the shaft 16. A corresponding change gear 23 is also selected and engaged with the shaft 22 and'the plate 26 wards and from the brush back and the ejection of a tuft from said nozzlein'to engagement with the registering hole in the back. Each time the nozzle is withdrawn the cams 17 and 18 operate to shift the table and the brush holder thereon so as to bring another hole in registration with the nozzle when it is againmoved downward. Preferably the which thefinished brush maybe removed from its clamp 47 and a new drilled back inserted in this clamp ready for another operation. r p r What I claim as my invention is: r

1. The combination with tuft" setting mechanism, of a laterally movable work support, cooperating cams for moving said work support in transverse directions, mechanism for driving said cams in' timed relation to said tuft setting mechanism, and a work means mounted on said support and slidably movable independently of said support -be tween stops thereon to alternatively bring either of said retaining means into operative relation to said tuft setting. mechanism, wherebya finished brush may be withdrawn from the holder out of registration with the tuft setting mechanism and a new brush back inserted therein during the operation of said mechanism on the work in the holder in registration therewith.

2. In a brush making machine, the combination with a reoiprocable tool for operating on a brush back, of a laterally movable work support, a removable cam for operating said work support step by step: through a complete cycle, mechanism'for operating '95 holder having a pair of brush retaining said cam in timed relation to said tool, in-

eluding a removable gear and a second gear cooperating therewith, said removable gear having teeth corresponding-to the number of steps in a complete cycle, and'means for laterally adjusting the axis of saidsecond gear with respect to said removable gean.

3. In a brush making'machine, the combination of a vertical .reciprocable tuft setting mechanism, rotary means for driving said tuft setting mechanism, a work carrying table movable horizontally in transverse directions, a vertical spindle beneath said work carrying table, a pair of cam plates detachably connected to said spindle, said cam platesbeing provided with a series of steps connected by inclined portions, cam followers respectively cooperating with said cam plates, a removable gear connected to said spindle, a second gear meshing with said removable gear, a movable support for said second gear permitting lateral adjustment of the axis thereof with respect to said removable gear, a driving mechanism between said rotary means and said second gear, and a coupling in said driving mechanism permitting adjustment of the timing 10 of said cams relative to said tuft setting mechanism.

In testimony whereof I aflix my si nature.

CONRAD JOOBST.
