IMPROVEMENT IN CARDlNG-ENGINES.

Specification forming part of Letters Patent No. 50,377, dated October 10, 1865.

To all whom t may concern:

Be it known that I, HAMILTON L. MoUL'roN, of Camden, Camden county,'New Jersey, have invented certain Improvements in Oarding-Engines, and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists of a revolving drum or cylinder, provided with combs, caused to operate by stationary cams and springs, substantially in the manner described hereinafter, in combination with the dofting-cylinder of a carding-engine, for the purpose of stripping from the said dofng-cylinder a more uniform sliver of fibers than can be obtained by the use of the ordinary strippingdevices, the wear and tear of the cardingengine being at the same time`mucl1 reduced by the application of my improvement.

My invention further consists in the combination of the said stripping-cylinder, dofflngcylinder, and a tube, the whole being caused to revolve in the direction pointed out hereinafter, so that a strong and regular sliver may be produced.

In order to enable others skilled in the art to make and use myinvention, I will now proceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part of this specilication,Figure l is a side view of sufficient of a carding-engine to illustrate my invention; Fig. 2, a sectional plan of Fig. l; and Eig. 3, a transverse section of the stripping-cylinder, drawn to an enlarged scale.

A and Al are the opposite side frames of the machine; and B, the dofng-cylinder, the shaft C of which turns in suitable boxes, a a, on the said side frames.

Near the front end of the machine is a shaft, D, to which is secured a cylinder or drum, E, composed of the circular ends or heads d, con. nected together at their peripheries by slats c. The shaftD projects through and turns in the cams F, each cam having a proj ection, f, which is secured to a suitable box, b, on one of the side frames.

In the cylinder or drum E are a number of narrow longitudinal slots, x, (there being four in the present instance,) each slot being such as to contain one of the combs h, and permit the same to slide freely toward and from the shaft D. Each comb has at each end a projection or pin, i, carrying a roller, j, the several rollers being caused to bear against the peripheries of the cams by springs m, (shown in dotted lines, Fig. 2,) there being in the present instance one spring to each comb, one end of each spring being secured to the heads or slots of the cylinder, and the other end being turned down through a hole in the comb. rlhe cams are of such a form and the combs and drum or cylinder are of such dimensions that when one of the combs arrives at the pointy its serrated edge shall project outward from the face of the cylinder to a distance of about fivesixteenths of an inch, but on passing from the pointy shall recede into the cylinder and remain there until it again approaches the pointy; in other words, the combs remain drawn inward from the face of the cylinder at all times, excepting when approaching and leaving the point y.

A tube, H, is caused to revolve in a box or bracket attached to one of the frames, this tube being in a proper position for receiving the sliver as it is stripped from the dofngcylinder B. This cylinder and the tubeH may be driven in the direction of their arrows by any suitable system of belts or gearing, but I prefer in all cases to drive both from the shaft C, so that e the doffing-cylinder, tube, and stripping-drum may operate in unison. As the dofting-cylinder revolves in the direction of the arrow the fibres collected in the card are stripped therefrom bythe combs of the revolving cylinder and leave the card in the shape of an uniform sliver, which passes through the revolving tube H.

A most important feature of myinvention is that each comb during one revolution acts with stripping effect on the dofng-ca-rd for a very brief time, and that each comb always remains withdrawn into the cylinder, excepting during its brief action. Hence there is no possibility ofthe fibers being carried round. At the same time the sliver is uniform and perfect.

Another important feature of my invention is causing the dofingcylinder, stripping-cylin` der, and tube A to revolve in the direction of the arrows, as by this arrangement the fibers are stripped from the card in a direction the same, or nearly the same, as that in which the sliveris twisted bythe revolvingtube. Astrong sliver is thus produced. In fact, the fibers, as they are stripped from the Cardcylinder, are

rolled during the stripping process in the direction in which they are afterward twisted by the tube.

It will be evident that by the substitution of the revolving stripper for the ordina-ry recipmeeting comb the weer and tear of the engine is much reduced.

I do not desire to confine myself to any speciiic number of combs or to the precise devices described for operating the said knives; but

I claim as myinvention and desire to secure by Letters Patent- 4 1. The revolving drum or cylinder, with the combs h and the springs m, or their equivalent,
