GLEARER-ROLL FOR, DRAVIING, RGVING, AND SPINNING FRAMES.

To all whom it may concern Be it known that we, MAncELLUs GOULD and NELSON C. CLoUnrrn, citizens of the United States, and both residing at Penacook, in the county of Merrimack and State of New Hampshire, have jointly invented a new and useful Clearer-Roll for Drawing, Roving, and Spinning Frames, of which the following is a specification.

Our joint invention relates to drawing, roving and spinning frames in which clearer-boards or other cleaning devices are employed as top-roll clearers of accumulating waste, short-fly and dirt, the clearerboard most commonly in use being attached to the under side of the hinged-metal-cover of the rolls, and provided with a layer or strips of flannel or other like material, which lies lightly upon the top-rolls, for the purpose of gathering up and holding the waste, short-fly and dirt, usually called the clean away, constantly accumulating on the leather-covered top rolls.

It is well known to those familiar with the practical operation of drawing, roving and spinning frames, and especially of roving machines, whet-her slubbers, intermediates, fly-frames or jack frames wherein longstaple cotton is used, that the percentage of the clearaway adhering to the top-rolls, particularly the front toproll, is very considerable, and that constant care must be exercised, and much time employed, in removing the clearaway from both the clearer-board and the top-rolls, lest the clearaway be drawn into the roving or yarn and form slugs or bunches, frequently resulting in breakages of the roving or yarn.

Ne are aware that cleaning-rolls have been invented for use in machines of the character above soecified, but they are of such formation, and concentrically revoluble, that their surfaces, traveling in revolution at the same rate as the top-rolls, do not have sufficient frictional engagement with the latter to remove the clearaway, but rather tend to collect and press the clearaway into bunches on the top-rolls, to be the more readily dropped or drawn into the roving or yarn.

The object of our joint invention is to provide eccentrically revoluble clearerrolls, which shall lay, gravity held, upon a top-roll,

larly described; illustrated in the drawings,

and covered by the claims.

In the drawings, wherein like letters of reference indicate corresponding parts in all Ithe views :Figure 1 is a transverse sec-- tional view of a sufficient portion of a roving machine-fly-frame to show the adaptation of our invention. Fig. 2 is a top view of a similar section of a fiyframe with one of our clearer-rolls in operative position. Fig. 3 is a view in perspective of our front clearer-roll and so much of the front toproll of a fly-frame and its connecting parts as will show the manner of operation of the clearerr0ll. I

A is a portion of a roving machine-fiyframe, a top-rolls usually of iron, leather covered, Z) bottom rolls, steel, fluted, (Z yarn or roving, e hinged metal cover, upright lugs or stops fdr cover, 9 front clearer-roll, 2 eccentric shaft of clearer-roll, and 7c flaniel covering of clearer-roll.

In the practical operation of our joint in vention, the front clearer-roll lies atop the front top-roll, and the rear clearer-roll atop and between the middle and rear top rolls, both clearer-rolls rotated by the top-rolls, with the eccentric shaft of the clearer-rolls bearing against upright lugs or stops and freely movable, up and down, thereagainst, as the clearer-rolls rotate, the rotary motion of the clearer-rolls being sufficiently retarded by the oscillating, longitudinally rubbing movement imparted by said eccentric shafts movably bearing against said lugs or stops, whereby the proper frictional engagement is made to insure the taking up of the clearaway.

Our clearer-rolls are covered with flannel or like surface cloth. In the exact type and formation herein shown and described, our device has been in successful operation without removal for cleaning, for periods of more than a week continuously, as compared with the necessary frequent daily cleaning of the clearer-board so commonly used. It

is found that with the use of our clearerrolls, the tendency of the clearaway to gather on and clog the bearings of the toprolls, especially the front top-roll, common in the use of the clearer-board, is obviated.

While we have preferred to construct these clearer-rolls of wood, they may be made of any other suitable material, which, held to the top-rolls by gravity, will cause the proper frictional engagement with the latter without sufficient friction, however,

to appreciably retard the speed of the machine rolls.

Having fully described our invention, we claim:

1. In a machine of the class specified, the

, combination with the top-rolls of a clearing device, consisting of a roller having an eccentric shaft, said roller bearing upon and given a rotary motion by said top-rolls, said eccentric shaft bearing against upright stops and adapted by the free vertical movement of said shaft to impart an oscillating motion to said roller while rotating.

2. In a machine of the class specified, the combination with the top-rolls of a clearing device, gravity held in engagement with the top-rolls, said clearing device consisting of an eccentric shaft and a cylinder rigidly mounted on said shaft, said shaft to movably engage uprights attached to the frame, and thereby impart an oscillating and longitudinal rubbing movement to said cylinder in its rotation.

3. A clearing device for the rolls of drawing, roving and spinning frames, consisting of a roller adapted to lie upon and be rotated by said rolls, said roller being circular in cross section and having an eccentric shaft intended to movably engage vertical stops fixed in the frame, whereby said roller in rotating isgiven an oscillating and irregular movement.
