CIRCLE COMBING-MACHINE.

Specification of Letters Patent.

Patented Mar. 14, 1911.

Application filed April 25, 1910. Serial No. 557,455.

To all whom it may concern:

Be it known that we, JOHN HENRY WHITE- HEAD and GEORGE GALLowAY, subjects of the King of Great Britain and Ireland, residing at Leeds, in the county of York, England, have invented certain new and useful Improvements in or in Connection with Circle Combing-lVlachines'; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in connection with the feed of balled wool or other fiber in circle combing machines, with the object of obtaining greater uniformity in the tension on the wool as the balls are unwound, and therefore greater uniformity in the feed and in the threads afterward produced from the wool.

For the sake of brevity and clearness of description we have annexed hereto the accompanying two sheets of drawings, of so much of a circle combing machine as is necessary to illustrate our invention.

In these Figure l is a plan on line A A of Fig. 2. Fig. 2 is a part side elevation.

and a part section on line B B of Fig. 1. Fig. 3 is a perspective View of the plate carrying the supporting rollers. Fig. 4 is a longitudinal section, Fig. 5 a cross section, and Fig. 6 a plan to a larger scale illustrating the essential part of our invention, in which a so-called pan is used to support the wool balls in place of the usual supporting rollers.

a indicates the bed or frame of the machine.

.7) are the balls of wool or silver, each of which is usually supported loose on a pair of supporting rollers c and cl, carried in slot bearings in the ends of horizontal bearers c; the latter being carried by hangers f suspended from the large comb circle 9. Since the balls I) gradually decrease in size and weight as the wool is fed from them, the tension or pull on the wool passing from the ball to the feed boxes varies, and this causes a want of uniformity in the feed. To avoid this defect it has been proposed to lift the rollers c and d a sufficient distance to produce a slackness in the sliver between the balls and the feed boxes, immediately preceding and during the time of the feed. This has been effected in some instances by carrying the rollers at the ends of two armed or bent levers, the opposite arms of the levers bearing against the vertical face of a pair of cams, extending partly around the outside of the bed or frame of the machine. In other instances rollers carrying above them the supporting plates or frames of the balls are arranged to run on a plate having a downwardly inclined end by contact with which they are successively lifted to slacken the sliver. Now this invention consists in improved and simplified means for efiecting this temporary lift of the sliver balls. For this purpose we form the fixed cams h as parts of a circle, concentric in plan with the large comb circle, so that the upper surface is the operating part of the cams. Each cam is bent downward at both its ends, as shown at h Fig. 2, so that the lower end of a projection or rider 71 formed on or attached to the under side of the supporting plate 7', rides up one end of the cam and remains supported until reaching the other end of the cam; when it rides down to its original position.

is Fig. 3 are slot recesses in the cross pieces or bearers e of the supporting plate j forming the bearings for the supporting rollers c and d.

m are tie bars bolted to the horizontal flanges at the lower ends of the hangers f, which according to this invention are provided with guide sockets n to receive the guide pins 0, attached to underside of the supporting plate j; and with a central hole to permit of the passage of the beforementioned projection or rider 2', by means of which the plate 7' is lifted. To lessen the friction in riding over the cams h, rollers 79 are fitted to the lower ends of the rider z'. The cams it are carried from the bed or frame a, so that they can be readily adjusted in position; horizontally by means of slot and bolt connection 9, and vertically by means of a similar slot and bolt connection 1".

Figs. 4 to 6 show the invention applied to the case where an open ended trough s, with curved sides, technically termed a pan, is used for supporting the sliver ball b; in stead of the rollers c and cl. The same reference letters are used in Figs. & to 6 as in Figs. 1 to 3 to indicate the same or corresponding parts. A single pan is shown in Fig. 1.

t are the bridge pieces, through which the sliver passes to the feed boxes. I

1. In a circle combing machine ill-which each ball of wool 1s raised immediately prior to and kept raised during the feed, the combination of a pair of horizontal partly circular cams, concentric in plan with the large comb circle and bent downward at both ends, supports or carriers for the balls of wool, a pair of guide pins and a. depending projection or rider attached to each of said supports or carriers, fixed tie bars between the lower ends of the hangers from the large comb circle, provided withfguide sockets for said guide pins said cam plates horizontally and vertically,

a pair of ball-supporting rollers, a-support ing plate in which said rollers are-journaled, a rider depending from, this plate and arranged; to ride on said cam plates and lined guides'for the said supportingplate as, it risesand falls.

3. In a circular combing machine in which; each ball is raised immediately prior to the feed and kept raised during the same, the combination of a pair of horizontal partly circular cams concentric in plan with the large comb circle and bent downward at both ends, a pair of ball. supporting rollers, a supportingv plate in which said rollers are journaled, a rider depending from this plateand arranged to ride on said cams andifixed guides for the said supporting plate as it rises and falls.

In testimony whereof, we have-signed our names to I this specification in, the presence of two subscribing witnesses.
