`CLEARER FOR SPINNING-MACHINES.

.SPECIFICATION forming part of Letters Patent No. 534,616, dated February 19, 1895.

Application iled January 22, 1894:. Serial No. 497,636. (No model.)

To all whom t may concern:

Beit known that I, WILLIAM C. PEIRCE, of Providence, in the county of Providence and State of` Rhode Island,have invented certain new and useful Improvements in Clearers for Spinning Machines; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specitication.

This invention has reference to improvements in clearers for top-rolls which are particularly adapted for use on roving-frames.

The object of the invention is to construct a clearer, of the nature described, which will act at all times on all the top-rolls.

Another object is to so construct a double clearing-device that it may readily be removed from the machine, while it is h eld from moving forward unduly.

The invention consists in the peculiar construction of the clearer-rolls and in the side arms to which they are secured.

The invention also consists in such other novel features of construction and combination of parts as will hereinafter be more fully described and pointed out in the claims.

Figure 1 represents an end view of therollbracket of a roving-frame-showing the drawing and top rolls with the improved rack and the clearer-device. Fig. 2 represents a vertical sectional view of the same to more clearly show the location of the clearer. Fig. 3 represents a front elevation of Fig. 1. Fig. 4 is a plan view of the clearer-device removed from the machine.

Similar numbers of reference designate corresponding parts throughout.

In the drawings 5 represents one of the end brackets in which the front drawing-roll 6 is journaled, and 7 the adjustable bearing-block in which the drawing-rolls 8 and 9 are journaled. Pivoted to the rear ends of these adjustable blocks 7 are end-frames 10-10 which are formed in two parts to allow of their adjustment so that the top-rolls 1l, 12 and 13,

which are j ournaled in bearing-slots in the frames, may be brought to bear on the respective drawing-rolls. From these end-frames lO-lO extend plates let-14 cut away at their upper portions to form arms in which the rods diameter.

15 are journaled, and on these rods, within the plates 14:, are clamped the sleeves 16-16 which prevent the longitudinal movement of the rods. The rods serve as supports for fliers, when not in use, or may be used for supporting a dust-shield. On the forward portions of the frames 10-10 near the bearings for the rolls 11 arey the Vertical-extensions 17-17. 6o

The clearer-device consists of two

clearerrolls

18 and 19 connected together by the arms 20-20 which have end sleeves or perfo-V rations through which extend pivots 2l and 22, these pivots being rigidly secured in the axial centers of the respective clearer-rolls. The arms 2O are furnished with stops 23-23 which, when the clearing-device is thrown too far forward, strike the vertical-extensions The rear clearer-roll 18 consists of a shaft 18 having enlarged portions 182 of a length equal to the length of the top-rolls and of a diameter to rest on the top-rolls 12 and13 and to be readily rotated by the frictional contact therewith. On the surfaces of these enlargements is secured the covering 24 consisting of a spiral band between the coils of which are left spiral grooves 25. This covering is generally formed of a tape or ribbon 8o of textile material having a teaseled surface adapted to take up the short fibers which adhere to the top-rolls and the edges form selvages which tend to hold the fibers so taken up when the fibers are brought into contact with the edges.

The clearer-101119 is of a similar construc-l tion 4to the roll 18 but is of a much smaller diameter and rests, in its normal position, on the top-roll 11 slightly in front of its vertical 9o The central enlargement 192 is, however, continued for a length equal to the length of the two central top-rolls l1 and for the spacebetween these rolls. The covering 26 on the enlargements is arranged in spirals 95 extending the length of the enlargements and having grooves 27 between the coils, as in the construction of the clearer-roll 18, the material being also similar. It is, however, evident that dlerent materials or grades of maroo terial may be used on the clearer-rolls, and textile material, or other suitable material,

such as leather with a rough surface, or any other material which is adapted to collect the short fibers from the top-rolls.

As the short fibers are carried around by the top-rolls into contact with the clearerrolls, they are engaged by the covering of these rolls which, being arranged in spiral coils, exerts a wiping action by the edges of the spiral coils on the top-rolls and also tends to drive the bers toward and into the grooves between the coils of the covering where the edges of the covering tend to more securely hold the fibers. In practice it is found that when these clearer-rolls are iirst placed in operation the

grooves

25 and 27 become filled before an appreciable thickness is added to the surface of the covering, although at all times there is a difference in the density or compactness with which the bers are packed in the grooves and on the surface of the covering, so that when the rolls are completely iilIed, the wiping actionof the spiral covering is, to an extent, maintained.

of rolls consisting of the rolls 11, 12 and 13 each of which is supported by a corresponding roll in the lower series, and bearings, in which the upper series of rolls is journaled, adapted to locate the same on the lower rolls, of the rear clearer-roll supported by the toprolls 12 and 13 and adapted to be driven by frictional contact therewith, side arms pivoted on studs axially secured in the ends of the rear clearer-roll, and a front clearer-roll rotatably secured between the forward ends of the side arms and supported by the same against the surface of the top-roll 11 and in front of its vertical axial plane.

2. The combination with the roll 18 having the enlarged portions 182 and provided with the spiral covering 24, and the pivots 21 axially secured inthe ends of the roll, of the roll 19 having enlargements of a smaller diameter than those of the roll 18, said enlargements being provided with spiral coverings studs or pivots 22 axially secured in the ends of the smaller roll, and the arms 20-20 having the stops 23-23 and journaled on the pivots of the respective rolls, as and for the purpose described.

In witness whereof I have hereunto set my hand. f
