CARDING-MACHINE Patented Oct. 8, 1907.

Application filed June 18, 1906. Serial No- 822,276.

To all whom it may concern:

Be it known that ROBERT B. ROBINSON, a citizen of the Dominion of Canada, and EDDO V. BArEs, a citizen of the United States, both residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Carding-Machines, of which the following is a specification.

This invention relates to machines for carding or straightening the fibers of wool, cotton, or other stock.

It relates to what are known in the trade as reworking cards. Itmay be applied to the first or second breaker or to the finisher card.

In the drawings, Figure 1 is a diagrammatic side viewleft of the machine, Fig. 1, by feeding in rolls, inter-' mediate, and licker in, in the usual way. It is carried forward by the swift or main cylinder B which travels at a very high rate of speed, and after being carded as it passes the workers G D, it is delivered by the fancy C and doffer II, also in the usual way. To arrange our workers in pairs G D, G D, Fig. 1. In this drawing, three pairs are shown but a greater number or a less number of pairs maybe used.

v The teeth of workers G and D are set in the same direction and point to point with those on main cylinder B, but while worker G revolves in the same direction as main cylinder B, worker D revolves in the opposite direction. These workers are arranged to be in carding contact with main cylinder B, but not in carding contact with each other.

Between the workers of each pair is a transfer roll E with teeth set oppositely to those on the workers and arranged to be in carding contact, or more properly in stripping contact, with workers G and D and also with main cylinder B. This transfer roll revolves in the same direction with worker D and at a somewhat greater surface speed. The stripper F is located in front of worker G whereby it may be stripped and the stock re placed on main cylinder B. This stripper F revolves at a considerably greater surface speed than worker G, and main cylinder B revolves at a much greater surface speed than stripper F.

The workers G and D in this construction are not in carding contact with each other and the transfer roll E is preferably about one half the size of workers G and D.

Worker D is the slowest as to surface speed; transfer roll E is somewhat faster; worker G is considerably faster than transfer roll E; stripper F is somewhat faster than worker G, and the main cylinder B is very much faster than stripper F.

Any suitable arrangement of belts or gears may be used in our machine for driving the workers, strippers,

and transfer rolls at the required speeds. The trans-v fer roll E may be provided with straight teeth instead of with the bent teeth of ordinary card clothing.

In our machine, the stock is carried forward by the main cylinder B and the first carding takes place between the main cylinder B and the first worker G. Some of the stock It is carried back from this point by first worker G and is stripped therefrom by the stripper F and returned to the main cylinder. The rest of the stock is carried forward and is again carded between the second worker D and the main cylinder B. The carding at this point between the second worker D and the main cylinder B is the more effective from the fact that the teeth of the second Worker D have been cleared by the transfer roll E which acts as a stripper to worker D, before said teeth reach the point of carding proximity with the main cylinder B. Part of this stock is carried along by the main cylinder to the next pair of workers, and a part S of the stock is forced into the teeth of the second worker D, which have been cleared by the transfer roll E and are ready to receive the stock. This stock S is carried around by the second worker D until it reaches the point of contact with transfer roll E by which it is stripped and carried over to the point of contact with worker G. As the teeth of the'first worker G have been cleared by stripper F and as worker G travels faster than transfer roll E, the stock S is stripped from transfer roll E and carried along by worker G to its point of carding contact with the main cylinder B. At this point, part of this stock S is recarded and the rest is carried back and stripped by stripper F and replaced on the main cylinder B.

The object of placing transfer roll E in carding or stripping contact with main cylinder B is to keep the teeth of transfer roll E cleared of any surplus stock or flyings T which may remain thereon beyond its point of contact with worker G. This surplus stock and flyings T is more apt to be produced when any of the teeth of worker G get jammed back, straightened, or become bent, broken or clogged with stock from any cause. When such irregularities occur they are taken care of by the teeth of transfer roll E, being cleared by main cyl,

inder B. If the teeth of transfer roll E were not so cleared, by main cylinder B, they might fill up with stock to such an extent as to be useless. Another ad- 'vantage is that it is more convenient in fitting the work- I ers and. the transfer roll E and in adjusting them than in other forms of reworking cards.

What I claim as my invention and desire to cover by Letters Patent is,

In a carding-machine, the combination of a main cylinder and a plurality of sets of rolls cooperating therewith, each set including two workers which engage the main cylinder but do not engage each other, a transfer- 10 roll of such size and location as to engage both workers and the main cylinder for transferring stock from the second to the first worker, and :1 stripper for taking stock from the first worker and replacing it upon the main cylinder.

In testimony whereof we :lilix our signatures in presence of two witnesses.
