T0 at whmn it HUI/Z] concern.-

Be it known that I, J AMES THOMSON, a citizen of the United States, residing at Pawtucket, in the State of Rhode Island, have invented a new and useful Improvement in RollClearers, of which the following is a specification.

My invention relates to an improved rollclearer adapted for clearing the lint and waste from the drawing-rolls of cotton-spinning machinery; and it consists in atraversing rollclearer actuated in its reciprocating movement over the surface of the revolving roll by means of the sliver which is being drawn between the rolls, as hereinafter set forth.

In the accompanying drawings, Figure 1 represents an end view of the top rolls and a transverse section of the lower rolls, showing the position of my improved roll-clearer between the adjoining sets of drawing-rolls. Fig. 2 represents a side elevation with the forward set of drawing-rolls removed. Fig. 3 represents a similar side elevation showing the application of my improvement to top rolls adapted for a single sliver. Fig. 4 represents the sets of drawing-rolls as in Fig. 1, with a clearer operating upon both the upper and lower rolls. Fig. 5 represents a side view.

of the said clearer when removed from the rolls. Fig. 6 represents the same when arranged for the action of a single sliver. Fig. 7 represents a side view of the upper and lower clearers shown in Fig. 5 when they are separated from each other. Fig. 8 represents a side view showing the upper and lower clearers connected by means of a plate, as shown in Figs. 1 and 2, the central tongue being extended downward and frictionally connected with the lower clearer. Fig. 9 represents the sets of drawing-rolls as in Fig. 1, showing a clearer of a different construction. Fig. 10 represents a side view of the clearer shown in Fig. 9 when removed from the machine. Fig. 11 represents a partial top view of the rolls of a drawing-frame provided with my improved clearers for the upper and lower rolls, the hinged cover being broken away to show the rolls. Fig. 12 represents a section taken in the line 12 12 of Fig. 11. Fig. 13 represents an enlarged face view of the improved clearers when removed from the rolls. Fig. 14 represents an end view of the same.

Fig. 15 represents an under view of the lower clearer.

In the drawings, A A A represent the lower rolls, and B B B the top rolls, of a cottonspeeder.

0 represents the reciprocating guide-bar for delivering the slivers to the drawing-rolls, and D D the clearers, the said clearers being caused to reciprocate back and forth by'mean s of the downwardly-e xtending guide-plates E E, which are provided with the slits e e at opposite sides of a downwardly-extending tonguef, the said slits being adapted to receive the slivers g g, which are drawn by the sets of rolls A B A B and prepared for the spinning operation, the said slits e 9 being preferably made fine enough to catch the bunches which occuroccasionallyin the sliver, and when the slivers g g are carried back and forth by the reciprocation of the guide-bar O the resulting lateral movement of the slivers as they pass between the drawing-rolls will be imparted to the clearers, causing them to traverse back and forth along the surfaces of the adjoining top rolls, upon which they rest, thus keeping the said top rolls clean and free'from lint. V The application of my improvement to a top roll the bosses of which are adapted for a single sliver is shown in Fig. 3, in which the guide-plate E, which extends downward from the clearer D, is provided with a single slit 6 and made a little wider than the clearer to which it is attached. The clearers D D are preferably made in semicircularforin in their cross-section, as shown in Fig. l, and have their lower bearing-surfaces covered with cloth ct, as usual in top roll-clearers.

A clearer for the lower rolls A A may be combined with the clearer for the top rolls B B, as shown in Figs 4 and 5, the said clearers being connected to each other by means of the wires E E, which are turned so as to form a slit e for receiving the sliver and are loosely held in the perforations made in the upper clearer D. The arms I) b of the said wires pass through suitable perforations made in the lower clearer D and by springing either inwardly or outwardly serve to frictionally retain the said lower clearer D in its adjusted position, and in this case as the slivers g g, which pass between the armsb and b, are being moved back and forth by the reciprocating of the guide-bar C a corresponding movement will be imparted to the combined upper and lower clearers D D. WVhen the clearers are employed on a spinning-frame, the wire arms Z) and b may be so bent as to lie close together, as shOwn in Fig. 6, and in this case the yielding elasticity of the resilient arm I) will serve to cause the guide E to automatically fit slivers of different sizes, the said slivers in their passage between the said arms serving to cause their required separation. Instead of employing the guide-wires E E to connect the upper and lower clearers they may be connected to each other by means of a plate E, (shown in Fig. 8,) the lower clearer D being frictionally connected to the said tongue, soas to be capable of adjustment thereon.

Another form of the clearer is shown in Figs. 9 and 10, in which the clearer D is made in cylindrical form, with the usual covering of cloth a, and having at its ends projecting journals 0 c, which are snugly held in the bearings cZ cl of the guide-plate, and in this case when the cloth covering of the cylindrical clearer becomes worn in use the clearer can be turned slightly, so as to bring into action a fresh wearing-surface, and so on until the cloth cover is entirely worn, the frictional bearings d 01 serving to retain the clearer in its adjusted position.

The slits g g in the plate E may be made so that the end of the slit willjust rest upon the sliver, and in this case when the distance between the rolls is to be increased in order to operate upon a'longer staple then the resulting fall of the clearer will serve to deflect the sliver downward, and thus increase the length of the sliver between the rolls, as shown in Fig. 9, so that in this case the adjustment may be effected by the movement of the top rolls alone without moving the bottom rolls, which latter adjusting movement requires a considerable time.

The application of my improvement in the roll-clearers to the rolls of a drawing-frame is shown in Figs. 11, 12, and 13, in which F represents the table of the drawing-frame; B, the top rolls; A, the under rolls, and G the sliver passing between the rolls. The upper and lower clearers D D may be made of wood in triangular form and connected with each other by means of the spiral springs H H, which at their upper ends are secured to the upper clearer D and at their lower ends are provided with a head It. The lower clearer D is provided at its opposite ends with notches Z Z, adapted to receive the springs H H, the heads 7c 76 of which serve to support the lower clearer yieldingly in its proper bearing position upon the under surface of the lower rolls, and at the same time the said springs may be readily moved out of the said notches Z l to cause the separation of the upper and lower clearers from each other, and whenever it is desired to remove the accumulated waste from either the upper or lower clearer then by pulling upon the buttonn of the said clearer the yielding of the springs H H will allow the removal of the clearer from the rolls to the required distance for the purpose of cleaning. The upper clearer D is provided with the downwardly projecting wooden guide-pins K K, which are adapted to embrace the opposite edges j j of the sliver. The separate slivers g g first pass from the holding-cans through the stationary guideeyes h h and thence to the traversing guide I of the machine, and by means of said traversing guide the collected slivers are caused to reciprocate back and forth in a single sliver G. The lateral edges jj, by engagement with the inner edges m m of the guide-pins K K, will serve to impart the required traversing movement to the clearers D D.

A beneficial effect is produced upon the sliver when it is pressed at its sides as it is being drawn by the rolls, and the yielding wires of the guides E may be made of the required gage to allow the inconsequential smaller bunches to pass through the slit by the springing of the wires and to stop the passage of the larger bunches, which would injure the quality of the yarn, and when the upper and lower clearers are employed the waste collected by the clearers will cause them to be moved apart, so as to retain the collected waste and keep itaway from the running sliver.

I claim as my invention- 1. The combination of adjoining sets of upper and lower rolls, with a roll-clearer and a sliver-guide which extends between the rolls from the clearer, and serves by engagement with the sliver to transmit the lateral movement of the sliver to the clearer.

2. The combination of adjoining sets of upper and lower rolls, with the upper and lower clearers, and a connection which extends from the one to the other between the sets of rolls, and serves to connect the clearers for simultaneous traversing movement.

3. The combination of the adjoining sets of upper and lower rolls, with the upper and lower clearers, and a sliver-guide extending between the rolls, and connecting the clearers with each other.

4. The combination of the adjoining sets of upper and lower rolls and the upper and lower clearers, connected with each other, with the guide-bars which embrace the edges of the sliver, and spring means for holding the clearers in yielding engagement with the rolls.

5. The combination of the adjoining sets of upper and lower rolls, and the upper and ranged between the said sets of rolls to emlower elearers, with spring means connected brace the edges of the sliver and partake of to one of the clearers and having a head the lateral movement thereof.
