Application April 20, 1927, Serial-N0. 1

:is invention relates to hnprm'enicnts -nbiug machines, and r to the teed motion for "bloble 'llhe usual teed motion consists of a trip arm 0; er ted by inclines or come from the part of ti o comb, which arm carries a y .i vl to operate a toothed wheel, which in turn moves the rollers, the wool being drawn to the COHll) by means of boxes and gear connected therewith. l find that this arrange ment is not entirely satisfactory, due to the we' it of material causing a tendency for a movement opposite in direction to the feed movement.

invention is in the nature at a rack ably operated to move a pinion which in turn operates a worm which engages and operates a worm wheel in connection with the rollers. his gives a positive teed, not subject to back lash, and obviates the use of the usual inclines.

T18 teeth on the rack may be made variable to suit the desired feed, and the teeth of pinion will be constant, but in an alternative form the teeth of the pinion may be variable as to teeth and the rack be constant.

Referring to the drawings which form part of this specification Fig. 1 represents a sectional elevation of a comb with my invention applied thereto.

Fig. 2 represents a plan.

Fig. 8 represents an elevation of an alternative form of construction.

Fig. represents a plan of the niechanisni shown in F1. 0.

F 5 and 6 re resent details of a moditieil 'l'orin of rock hereinafter referred to.

To carry my invention into ell'ect and with rotor-once to the 'awings which illustrate a convenient method of construction and modifications thereof, 1 wish it to be understood that I may further vary the details, so lo g as I operate the rollers F by means of a re :1: and pinion device actuating a worm wheel motion.

The existing castings and brackets or hangers of a Noble comb will be used where possible, filing, boring, or adding to 52111713 as may be tound necessary.

the form illustrated in fl and 2, suitable and rnreiterably adjustable bracket A mounted in connection with the j l: v a rack in this case connieinbei rt carrying pegs lit readdctachahle in. order that the length of 85,189, and in Great Britain June 23,

rack may be varied to alter the feed. The member it maybe moved in or out or the bracket A and the bracket A may be raised or lmvered to suit varying requirements.

he rack will engage a suitable wheel such whcelti carried on a shaft- S which L carried by a bracket H. attached "-l The shaft S the usual hangers i.

i rain; Res in er carries in a suitable position a worzn which engages a worm wheel ably carried from a bracket or bearing attached to the hanger H or bracket H. This worm wheel will have a preferably square boss 53 which will be engageable by a squared end F of the rollers F, one gear two rollers and giving to the same a re feci motion with freedom from baclr lash.

As before mentioned the teeth of llllQJiLCli may be varied as to numberand the rack be variable to length but alternatively I may use the wheel S as a change wheel and alter the number and pitch of teeth therein.

R ferring to Figs. 8 and a, in this form the rack mechanism comprises a spring box it carried by the bracket A and springs 18. will contact with a rack plate R which in turn will carry a rack R made in one or more portions. lhis rack will operate a wheel in the nature of a spin wheel 53* carried on the shatt S the other portions being as heretofore described.

Figs. 5 and 6 show a further modification of a rack device carried by the bracket A and con'iprising a bot-z like device It carried by fixable pinions R The box like device may have any suitable number of equal or substantially equal sides, each side or face carryinga rack of di'llerent length to enable to i is of a change to be quickly made, a set screw It being provided to fix the desired rack in position.

it will be seen that in addition to obtaining a constant and positive teed, such feed or traverse may be quickly and easily changed, either by, in some forms, changing the star and spur wheel and leaving the rack constant, or by changing the rack, and while ll prefer one motion to operate two rollers F, in some cases each roller may be operated independently. here two rollers are operated at once two racks per comb will be sulficicnt.

What l claim is:

i. In a feed motion for the teed rollers O'ii Noble combs, the combination of rotatable team 5 iii;

3. A feed motion for the feed rollers of Noble combs, comprising in combination,

a rotatable frame, a normally stationary, adjustable rack, a Wheel carried by said frame and adapted to contact with and be driven by the rack as the frame rotates, feed rollers mounted for rotation in said frame, a worm driven by said Wheel, and a Worm Wheel in one fl'fifll'lfilll; therewith and engaging the arbors of said feed rollers for imparting a positive 'l'eell motion thereto.

4:. A feed motion for the feed rollers ol Noble combs, comprising in combination, a rotatable frame, a stationary rack, a removable wheel carried by said frame and adaptec'l to contact with and be driven by the rack as: the frame rotates, feed rollers mounted for rotation in said frame, and

' WO1J11 gearingbetween said wheel and the arbor-s of said feed rollers for in'lparting a positive feed motion thereto.

In testimony \i hereof' I have signed my name to this sjieeil'ieation.

BENJAMIN CRAVEN.
