JAMES THOMSON, JR, OF PAWTUOKET, RHODE ISLAND, ASSIGNOR TO THE THOMSON MANUFACTURING COMPANY, OF PROVIDENCE, RHODE ISLAND.
ROTARY CLEARER FOR DRAWING-ROLLS OF COTTON MACHINERY.
SPECIFICATION formingpart of Letters Patent No. 593,971, dated November 16, 1897.
Application filed April 1, 1897- Serial No. 630,243. (No model.)
To all whom it may concern.-
Be it known that I, JAMES THOMSON, Jr., a citizen of the United States, residing at Pawtucket, in the State of Rhode Island, have invented a new and useful Improvement in Rotary Olearers for the Drawing-Rolls of Cotton Machinery, of which the following is a specification.
In-the employment of rotary clearing-disks which bear flatly upon the rolls the cloth face of the disk is liable to be worn by the continued frictional action of the rolls thereon and a very considerable amount of power is expended in imparting rotary movement to the disk, the surfaces of the rolls at one side of the turning axis of the disk being caused to move in an opposite direction to that of the movement of the disk; and it is the object of my invention to avoid such Wear upon the surface of the cloth and to provide for the easier rotation of the clearing-disk.
To this end my invention consists in supporting the rotary clearing-disk with the plane of its face in a slightly-inclined position relatively to the plane of the adjacent surfaces of the rolls, a portion of the face of the disk.
at one side of its turning axis being arranged in driven contact with one or more of the rolls, while the face of the disk at the opposite side of the turning axis is held away from bearing contact with the said rolls, thus preventing wear of the cloth surface of the disk by frictional engagement between the face of the disk and the adjacent oppositely-moving surfaces of the rolls and facilitating the rotation of the disk. In the accompanying drawings, Figure represents a front view of the drawing-rolls,
an edge view of the inclined clearing-disk;
and a longitudinal section of the cover for the rolls. Fig. 2 represents a similar view showing a diiferent method for causing the required inclination of the clearing-disk from the plane of the rolls. Fig. 3 represents a section taken in the line 3 3 of Fig. 1.
In the drawings, Fig. 1, A represents the leather-covered rolls, having their upper surfaces arranged in the same horizontal plane, 13 the lower fluted rolls, and O the cover for the rolls, usually pivoted to the frame of the'machine by means of the cars is. The clearing-disk D is provided with a turning axis E, preferably screwed into the disk,
so as to be removable therefrom, and provided with a head I), which rests against the top of the cover whenever the said cover is raised from the rolls, the said turning axis E being loosely held in the bearing-perforation c in the top of the cover and in the bearingperforation d in the bracket F, the bearingperforation cl being so set relatively to the bearing-perforation c that the turning axis E will be thrown slightly out of a vertical position and the plane of the face f of the disk D will be slightly inclined to the plane of the top of the rolls A. When the cover 0 is raised, the disk D will be supported by means of the head I), which then bears upon the top of the cover, and when the cover is brought down to cover the drawing-rolls the lower edge e of the face of the inclined disk D will come in contact with one or more of the rolls A, thus causing the rotation of the disk in the same direction as that of the engaged surface of the rolls, while the opposite edge e of the face of the disk will be slightly elevated from the rolls, so that the rotation of the rolls in a direction opposite to that of the movement of the disk at the side 6 will not interfere with the free rotation of the disk caused by the So frictional contact of the lower edge e of the face f at the opposite side of the axis of the disk D with the upper surface of one or more of the rolls A, and by this means the wear of the cloth surface. a of the disk D by frictional 8 5 contact with the oppositely-moving surface of the rolls A at the side e will be prevented, and as the disk D revolves the waste will be collected in a felted sheet upon the surface of the disk, and this accumulation of waste will serve as a means for clearing the constantlyaccumulating waste from the surface of the rolls under the elevated portion 6 of the disk. Another form of construction is shown in Fig. 2, in which the face of the clearing-disk 5 D is inclined for revolution by means of the bracket F, secured to the boss g by means of the screw h, so that when the disk D is freely suspended, with the head I) of the turning axis E of the disk resting in contact with the upper side of the said bracket, the face f of the disk will lie in a horizontal position slightly above the plane of the upper surface of the rolls A, and under the head of the fastoning-screw h is placed the flat spring a), provided at its outer end with the antifrictionroller j, which bears upon the upper side of the supported disk and depresses the edge e of the face of the disk into contact with the surface of one or more of the rolls A, causing the elevation of the opposite edge e of the face, so that the disk at the edge e will not be in frictional contact with the oppositelymoving surface of the rolls, and With this construction a very slight pressure of the spring 2' upon the disk will serve to cause its rotation over the rolls for the proper collection and accumulation of Waste.
I claim as my invention- 1. The combination of the drawing-rolls, with a rotary clearing-disk having the plane of its clearing-face supported in an inclined position relatively to the plane of the adjacent surfaces of the rolls, a portion of the face of the clearing-disk at one side of its turning axis being held in driven contact with one or more of the said rolls, while the face of the disk at the opposite side of its turning axis is held away from bearin g contact therewith, substantially as described.
2. The combination of the drawing-rolls, with an axially-supported rotary clearin gdisk, and means for depressing the face of the clearing-disk at one side of its turning axis, to contact With one or more of the rolls, thus causing the rotation of the clearing-disk with the face of the disk at the opposite side of its axis held out of bearing contact with the rolls, substantially as described.
