FRENCH B. WILLIAMS, 01? DALLAS, TEXAS.

COTTON-PACKER.

Application filed May 11,

2' 0 (LZZ whom it may concern:

Be it known that I, FRENCH B. WILLIAMS, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented new and useful Improvements in Cotton-Packers, of whlch the following is a specification.

This invention relates to improvements in tramping means for use in cotton gins and the like and the principal ob ect of the in vention is to provide means for imparting a reciprocatory motion to the tramper by a shaft and pinion which is driven cont1nuously in one direction.

Another object of the invention is to provide a pair of parallel racks connected together at the ends by curved portions with means for automatically causing the pinlon to pass from one. rack over the curved portion to the other rack at each end of the parallel racks.

This invention also consists in certaln other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully descrlbed, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation showing the upper part of a press provided with my in-- vention.

Fig. 2 is a view taken at right angles to Fig. 1 with the press box and tramper lock omitted.

Fig. 3 is an enlarged section on line 33 of Fig. 2. p

F i 4c is an enlarged detail view showing the side supporting the pinion end of the drive shaft.

Fig. 5 is a plan view of the invention.

Fig. 6 is a detail view showing the various positions assumed by the guide roller which is connected with the drive pinions.

Fig. 7 is a sectional detail view show ng the various positions assumed by the pinion and shaft at one end of the rack.

In these drawings 1 indicates the press box and 2 indicates the uprights for supporting the cross beam 3 above the box. These beams support the slide member l to the lower end Specification of Letters Patent.

of which is connected the tramper 5. These beams also support the means for reciprocating this slide member. As shown, the slide member isprovided with an elongated openmg 6 having curved ends and the walls of this opening are provided with rack teeth so that a continuous rack is formed composed of parallel side portions and curved end portions. The slide member is engaged by the guides 7, carried by the'beams and having the rollers 8 therein which engage the side edges of the slide member. These guides are connected together by the cross bar 9. A horizontal guide frame 10 is connected with the guides 7 and this frame receives the carriage 11, the rollers 12 of which engage the said frame. This carriage sup ports one end of the drive shaft 13 to which the pinion 14 is keyed, this pinion being arranged to engage the teeth of the continuous rack on the slide member 4. A roller 15 is also carried by said shaft, said roller being adjacent the pinion and this roller engages a guide bar 16 which is connected to the slide member 4 by the forked members 17, said members being offset to hold the guide bar 16 with its inner face flush with the face of the member 4 so that said roller will engage with the edges of said bar while the pinion is engaging with the rack. The forked members 17 are also so formed as to permit the roller to pass around the curved ends of member 16 and under said member 17. The drive shaft 13 is provided with a flexible joint 18 and said shaft may be driven by any suitable means. The means shown consists of the worm drive which is driven from any suitable source of power by a belt ul hifch engages the pulley 19 on the worm s 1a t.v

It will thus be seen that the rotation of the pinion by the shaft will cause the member a to move in one direction as the pinion en-' gages the teeth on one side, and when said pinion strikes the curved part of the rack it will cause the carriage to move to the other side of the opening so that the pinion will engage with the teeth on this side and thus cause the member 4c to move in an opposite direction. The roller 15 engaging the edges of the guide bar 16 will keep the pinion in engagement with the rack at all times. Thus the tramper will be reciprocated with the drive shaft rotating continuously in one direction.

It is thought from the foregoing descrip tion that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claim.

hat I claim is In an apparatus of the class described having a reciprocating member, a continuous rack on said member composed of parallel side portions and curved end portions connecting the side portions, a drive shaft, a pinion thereon engaging the rack, a guide bar carried by the reciprocating member and a roller carried by the shaft and engaging said bar for holding the pinion in engagement with the rack at all tlmes, the combination of a horizontally movable carriage sup- 20 porting the pinion end of the shaft and a track for said carriage.

In testimony whereof Iafiix m signature. FRENCH B. WIIZLIAMS.
