To aZZ "whom/t1? may concern: v

Be it known that 1, JAMES C. POTTER, of

Pawtuoket, in the county of Providence, and I in the State of Rhode Island, have invented a certain new and useful Improvement in Eveners for Cotton-Opening Machines, &c., and do hereby declare that the following is a full, clear,'and exact description thereof.

Cotton opening machines are provided with an evening mechanism that automatically regulates the speed of the feed rollto suit the thickness of cotton delivered thereto the aim being that, regardless of the thickness or number of laps received by the feed roll, the lap delivered as the product of the machine will be of uniform gage. Said evening mechanism comprises a pair of cone drums belted together, one of which cones is geared to the feed roll, and the other to a source of power, and the belt is automatically shifted along the cones to vary the speed. This point might be anywhere along the cones, and so near the ends thereof as to fallow but little automatic movement of the belt in one direction and hence diminish materially the scope of automatic variation of the speed of the feed roll, with'the result that an abnormal thickness, or an abnormal thinness of cotton delivered to the feed roll could not vary the speed of the feed roll to meet the condition, so that the product delivered by the machine would be defective.

The principal object of my invention is to obviate this condition, and render available the travel of the cone pulley belt the entire length thereof for the automatic control of the speed of the feed roll.

-In the accompanying drawings Figure 1 is a View partly in vertical section and partly in side elevation; Fig. 2 is an end elevation thereof. I

Referring to the drawings the evener mechanism shown, as in the case of my patent referred to, comprises two cones 10 and 11, and a belt 12 that is shiftable along Specification of Letters Patent.

the same by the action of a system of scale levers, not necessary to be described as the construction and operation'thereof are usual. On one end of the shaftof the upper or driven cone, is a pinion 13 which is removably secured to the shaft so that pinions of different size may be employed and,'hence, the speed of the gear 14 with which such pinion meshes, be varied. A change gearing is thus provided, and as is usual with change gears, the wheel 14 is journaled on a yoke 15 hung concentric with the shaft 16 of the. gear 17 which, through a pinionlS, receives motion from the wheel 14. The gear 17 is the pinion carrier of a differential gear of usual construction, including a ratchet wheel 19 on the shaft 16, adapted,

when motion is to be imparted to the shaft 16 from the differential gear, to be held by a pawl 200. The ratchet wheel 19 by a sleeve 20, is connected with the gear 21 with which the planet pinion 22 meshes as well as with the sun gear 23 keyed to the shaft 16. The pawl, at will, may be rocked into and out of ratchet wheel-engaging position by a suitable handle connected with a rod 24, which is attached to the pawl. On the shaft 16, is a bevel pinion 25 in mesh with a bevel gear 26 on the shaft 27 of the usual feed roll 28.

It will be seen that the running of the feed rollis wholly under the control of the pawl, and as the latter is very light, but

little effort is required to move it to engage Y the ratchet wheel to place the feed roll in operation, and to disengage theratchet wheel to deprive the feed roll of power.

To secure variation in the weight or thickness of lap delivered from the machine, all

that is necessary is to change from a pinion of one size on the driven cone shaft to one of a different size, and not shift the belt of the cones at all, and hence, the latter for its normal position is always at midlength of the cones so that the entire range of automatic change of feed roll speed, which the length of the cones affords, is available, and automatic control of thickness of the finished lap is secured under extremes of variation not possible where the normal speed of the feed roll is obtained by adjusting the belt of the cone gearing.

I employ no worm gearing between the driven cone and the feed roll, and, hence,

endwise pressure from that source being eliminated, the sensitiveness of the evener is increased.

Having thus describedjmy invention what I claim is- 1 r i V 1. In an evener mechanism for cotton openers, etc., the combination of the feed roll thereof, a belt and cone gearing, the belt being automatically shiftable along the cones, and means independent of shifting the belt for varying the speed of the roll. relative to the driven cone.

2. In an evener mechanism for cotton openers, etc., the combination of the feed roll thereof, a belt and cone gearing, the belt being automatically shiftable along the cones, and achange gear connection between said feed roll and the driven cone.

3. In an evener mechanism for cotton openers, etc., the combination of the feed roll thereof, a belt and cone gearing, the

belt being automatically shiftable along the cones, a difierential gear connection between the feed roll and the driven cone having a pawl and rat,chet,an d meansto operate the pawl of the differential gear'to control the running of the feed roll.

43 111 an evener mechanism for cotton openers, etc., the combination of the feed roll thereof, a belt and cone gearing, the belt being" automatically shiftable along the cones, and a change gear connectionbetween said feed roll and the driven cone, comprising a train of gears that includes a removable pinion on the cone shaft and a shiftable intermediate gear meshing with the pinion. In testimony that I claim the foregoing I have hereunto set my hand.
