SPECIFICATION forming part of Letters Patent N 0. 618,402, dated January 31 1899.

Application filed December 27,1897. Serial No. 663,541. (No model.)

To all whom it may concern:

Be it known that I, JAMES EDGE, mill manager, of High street, Gort on, in the county of Lancaster, England, have invented certain Improvements in Flat-Stripping Motions for Carding-Engines, (for which I have obtained Letters Patent of the United Kingdom of Great Britain and Ireland, numbered 18,115, dated August 15, 1896,) of which the following is a specification.

My invention relates to improvements in flat-stripping motions for carding-engines; and the object of my invention is to provide mechanism capable of stripping the short fibers from the flats more efliciently than the mechanism hitherto provided.

My invention consists, essentially, in means for giving to the stripping-comb an oscillating motion about an axis in conjunction with a rapid downward movement.

In the accompanying drawings, in all the views of which the same letters of reference are employed to indicate corresponding parts, Figure 1 is a partial front elevation, and Fig. 2 is an end elevation,of apparatus constructed according to my invention. Fig. 3 is an end elevation, and Fig. S" a partial front elevation, of a part of a slightly-diiferent arrange ment of apparatus constructed according to myinvention. FigsA and 5 are end elevations of parts of other slightly-different arrangements of apparatus constructed according to my invention; and Fig.6 is a front elevation, partly in vertical section, of arrangements employed according to my invention to move the stripping-comb lengthwise. Fig. 7 represents a side view and a plan of a modification of devices for turning the stripping-comb shaft. Fig. 8 represents a side view and a plan of another modification of such parts. Figs. 9, 10, and 11 represent a modification of the devices for producing a longitudinal movement of the stripping-comb shaft.

It is obvious that parts similar to some of those illustrated in the accompanying drawings as applied to one side of the cardingengines, of which portions are illustrated in the said drawings, are necessarily employed at the other side of such carding-engines.

The stripping-comb A, which is employed according to my invention, may be of any suitable form and may be supported in any suitable manner, being in the accompanying drawings illustrated as secured to a rod, bar, or shaft a, but must be mounted and capable of being oscillated in bearings carried by arms 0, which are placed one at each side of the carding-engine and are arranged to be oscillated about the axis of a shaft D, fast upon which they mounted. The shaft D passes over the top of the carding-engine in the ordinary way and receives an oscillating movement, being provided with an arm which projects from it and carries at its lower end a bowl 6, resting upon a cam F, which is revolved in any suitable manner, such as by being fixed upon or connected with some suitable revolving part of the carding-engine. The arrangement described insures that the oscillating movement imparted to the shaft D will be conveyed through the arms 0 to the stripping-comb A. According to my invention I cause the downwardmovements of the stripping-comb, in which the short fibers are stripped from the flats, to be quicker than the upward movements of such strippingcomb, and I do this by forming that part f of.

the cam F which by its action on the bowl 6 brings about the upward movement of the comb with a very gradual progression in a direction outward from the axis of said cam the comb A to move more rapidly while stripping the flats than when ascending between one downward stroke andthe next, and by so doing I render the action of the comb more effective than it would otherwise be. It is obvious that the cam F may be so formed that two or more downward and two or more upward strokes shall be perform ed by the comb A during each revolution of the cam F. In Figs. 1 and 2 the parts are shown in the positionswhich they occupy when the comb A I is at the highest point of its stroke and quite clear of the flats, of which only one is indicated at G, 9 indicating one of the disks or bowls around which the flats are made to pass.

Besides imparting to the stripping-comb A an oscillating movement of the kind already described I impart to it during such movement an additional movementthat is to say, an oscillating movement about its axis or the axis of the shaft, bar, or rod a, on which it is mounted-and this additional oscillating movement may be obtained in several ways, of which I will proceed to describe some by way of instances. In one method of imparting the said additional movement I fix on one side of the carding-engine, in a suitable position, a bracket II, formed with a hole or slot h, and on the comb or the part supporting it I fix an arm, finger, lever, or the like J, carrying a stud or pin j, which enters into the hole It. The stud j may be arranged to be adjustable, as is indicated in Fig. '7, which shows the studj as passing through a slot j, formed in the arm J, and as provided with a nut j by means of which it may be'secured in said arm. In this arrangement while the cam F imparts to the comb A the oscillation hereinbefore described the movement of the comb A in relation to the bracket H causes such comb A to also oscillate about its axis. Instead of the stud j being fixed in the arm J it may be fixed in the bracket II, and the hole or slot 9' to receive such stud j, may be made in the arm J, as illustrated by Fig. 8, and although it is preferable to employ one arm J and one bracket II an arm J and bracket II may be provided at each side of the carding-engine. In another method of imparting the said additional movement to the strippingcomb the stud 7' is dispensed with altogether, the arm J being formed in the manner indicated in Figs. 3 and 3 and made to project through a hole or slot h in the bracket H, the length .of the hole or slot determining the amount of the additional movement imparted to the comb, and in yet another arrangement for the said purpose an arm J projects on both sides of the stripping-comb, one part of the arm J bearing with one side against the bracket II, a spring or a weight It upon the other part of the arm J, as indicated in Fig. 4, serving to keep such arm J in contact with the bracket H. Further, instead of using an arm and a slotted bracket I may form on the bracket a rack K, as shown in Fig. 5, and fix on the comb or the shaft, rod, or bar on which it is mounted a pinion or sector L, which gears into or engages with the rack K, and so causes the comb to oscillate. From what I have said it is obvious that the additional oscillation of the stripping-comb can be obtained in many ways without departure from the nature of my invention.

In addition to giving the movements above described to the stripping-comb my invention also consists in imparting to such strippingcomb a longitudinal movem ent,so as to enable it to still more effectually strip the flats, and to obtain this movement I form in the combshaft a, as shown in Fig. 6, a spiral or helical groove,into which a stationary peg, pin, or the like a passes, or I form, as shown in Figs. 9

made to project, in either of which arrangements the oscillation of the comb-shaft will cause such comb-shaft to move lengthwise .both in the upward stroke of the comb and the downward stroke thereof.

Set-screws, lock-nuts, and other requisite and suitable means for enabling the various parts of the mechanism to be adjusted relatively to each other are provided.
