UNITED STATES PATENT OFFICE.
GEORGE BRADLEY, OE PATERSON,
NEIV JERSEY, ASSIGNOR TO JACOB S. ROGERS, OF
SAME PLACE.
- CAP-SPINNING FRAME.
Specification of Letters Patent No.
To all whom it may concern:
Be it known that I, GEORGE BRADLEY, of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Cap-Spinning Frames; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference denoted thereon, in which Figure 1 is a vertical sectional View of a portion of my cap spinning frame, and Fig. 2 is a horizontal section of the same, or a portion thereof, on the line S-S.
Similar letters of reference indicate corresponding parts in both the figures.
My invention relates to the traverse motion. In order to distribute the yarn uniformly upon the bobbin, either the bobbin or cap must traverse vertically. As these parts have been heretofore constructed the bobbin rests upon the wharve, and if the bobbin is caused to traverse while the cap remains stationary or the cap to traverse while the bobbin remains stationary, serious difficulties are involved in consequence of the new relations perpetually induced between important portions of the machine. If the cap rises and sinks new relations are formed at each instant between the cap and the guide wires, and if to remedy this the guide wires are also caused to traverse, new relations are then established at each moment between the guide wires and the front rollers. If on the other hand the cap remains stationary and the bobbin is traversed by giving a vertical movement to the wharve this operation alternately tightens and slackens the band by changing relations of the wharve and cylinder. These evils are serious and previous to my invention neither had been avoided without involving the other or one still more grave.
Mr John Thorpe described in a patent dated 1830 the employment of acap and grooved spindle with a bobbin traversed thereon but this could not be operated with pecuniary advantage as the spindle and cap were live and the work could not be driven at a high speed. This fact and the great difliculty of mending broken threads on this plan has forbid its introduction. The difficulty in mending broken threads arises from having to stop a live spindle in order 26,812, dated January 10, 1860.
to find the broken end on the bobbin and the serious difficulties met in operating it at a high speed are obvious. The cap being a considerable mass without a possibility of receiving lateral support a high rotary velocity is certain to engenderat intervals if not constantlya gyratory motion, which motion induces, by centrifugal force, a sufficient frictional adhesion between the bobbin and spindle to prevent the descent of the bobbin at the proper time and proper rate. These difliculties are more serious than attends the adoption of either of the other devices.
My invention avoids all these difficulties. Its nature consists in the employment of a tube with a groove extending longitudinally along its exterior, in combination with a collar of corresponding form, and with a dead spindle and cap, arranged and operated in the manner to be explained below so that while the combination is adapted to work as rapidly as the ordinary dead cap spindle the bobbin is traversed without changing the hoisting of the cap or tube.
To enable others skilled in the art to make and use my invention I will proceed to describe it by the aid of the drawings.
The dead spindle A is firmly secured in the spindle rail I which is fixed to the stationary portions of the frame. The cap B is mounted on its top in the usual manner. The tube O is fitted to turn freely upon the spindle A as is usual in the majority of cap spinning frames. The wharve or whirl D is permanently attached to O and the letter rests upon I through the intervention of a simple cup or changeable step M. The tube O is fitted with a loose collar E which is permitted to slide freely up and down thereon and is adapted to support the bobbin F on its upper face and to impart a proper rotatory motion thereto by friction. The collar E is compelled to turn with O by reason of the small pin E which is inserted through one side of, and forms a part of, E, and stands in a straight groove or spline 0 which is formed in the exterior of O. The collar EE is supported upon the lifting rail H, which latter is operated in the ordinary manner by a suitable connection J to the rocker arm K. By the motion of K the bobbin, while rotated by the friction of the collar EE has the proper traverse motion imparted to it without elevating or depressing the wharve D or the cap B. The traversing motion is therefore produced 7 without changing the relations of D to the cylinder P and also without changing the relations of B to G orof either to the front rollers L.
- The tube Cc, wharve D, and collar EE being the only parts which partake of the rotary motion of the bobbin,rno appreciable gyratory motion is produced andthe collar and bobbin sink like the rail H with perfect uniformity. I have in use several spinning frames constructed according to. my invention, and have driven them at speeds as high as eight thousand revolutions per minute without experiencing any serious my name.
GEORGE BRADLEY.
