BOBBlN-HOLDER FOR SPINNING-MACHINE SPINDLES.

SPECIFICATION forming part of Letters Patent No. 619,506, dated February 14, 1899.

Application filed October 13,1898. Serial No. 693,451. (No model.)

To all whom it may concern:

Be it known that I, THOMAS F. RoNEY, of Newport, in the county of Newport and State of Rhode Island, have invented a new and useful Improvement in Bobbin-Holders for Spinning-Machine Spindles; 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 specification.

This invention relates to an improvement in devices for holding a bobbin so as to revolve with the spindle of a spinning-machine 5 and it consists in the peculiar and novel construction by which the base of the bobbin is held between spring-actuated clamps and the thread end is secured, as will be more fully set forth hereinafter.

Figure 1 is a side view of a spinning-spindle, parts of which are shown as broken away, showing the blade of the spindle provided with a bobbin and also showing the bobbinholder in section. Fig. 2 is a top View, and Fig. 3 is a transverse sectional view, of the pivoted clamping-arms. Fig. 4 is a top View, and Fig. 5 is a sectional view, of a disk supporting the clamping-arms. Fig. 6 is a top view, and Fig. 7 is a sectional view, of the cross-plate resting on the coiled spring. Fig. 8 is a top view, and Fig. 9 is a side view, of the coiled spring. Fig. 10 is an end view, and Fig. 11 is a vertical sectional view, of a sleeve secured to the spindle. Fig. 12 is a top View, and Fig. 13 is a vertical sectional view, of the casing forming the base of the bobbin-support.

In the drawings, a indicates the spindle, a the whirl secured to the spindle, and a the blade of the spindle, b the bobbin, and b the base of the bobbin. The bobbin-support is made up of parts shown separately in the drawings and consists of the sleeve 0, adapted to be driven onto the tapering blade of the spindle and secured in the position required. The sleeve 0 is provided at the upper and lower end with a shoulder. On the upper shoulder is placed the ring a, on which the clamping-arms c c are hinged, as is shown in Figs. 2 and 3, in which four of the clamping-arms c are shown pivotally secured to or hinged to the ring 0. Two or more clamping-arms 0 may be used. The ring 0 is secured to the sleeve 0 by upsetting the upper end of the sleeve. The casing 0 which may be drawn up from sheet metal in the form of a cup, has the flange 0 provided with a number of openings 0 c contracted on the peripheral margin of the flange c. The openings o o are formed in the cylindrical side of the casing 0 and the hole 0 is formed in the bottom to receive the shouldered lower end of the sleeve 0. The arms of the cross-plate 0 (shown in Figs. 6 and 7) extend through the openings 0 c in the casing, and to facilitate the insertion of the cross-plate the openings 0 c are made wider on the lower portion than at the upper, where the arms of the cross-plate extend through the openings when in the operative position.

In associating the parts together the hole 0 of the casing c is placed over the lower end of the sleeve 0 and secured by upsetting the metal of the end of the sleeve 0 over the edges of the bottom around the hole 0 The coiled spring 0 (shown in Figs. 8 and 9) is now placed around the sleeve 0 in the casing, the crossplate 0 is inserted, with the arms extending through the openings 0 c and the washer 0 having the annular raised convex ring o is placed on the cross-plate c and within the annular flange c of the casing 0 The ring 0,

with the clamping-arms 0 is now placed on the upper end of the sleeve Q and secured by upsetting or riveting the metal of the end of the sleeve over the ring 0. In securing the parts to the sleeve the spring 0 has to be compressed so that it exerts a force on the cross plate 0 on the washer 0 and on the clamping-arms c 0 resting on the convex annular ring 0 whereby the said clamping-arms are forced upward and, turning on their hinges, are forced inward against the base I) of the bobbin to firmly clamp the same.

In the process of spinning yarn when the bobbins are filled the ring-rail or other yarnguide is moved down to wind some yarn on the bobbin-holder or spindle below the bobbin before removing or doffing the bobbin. With a bobbin-holder of my improved construction in the winding down before the doffing the yarn will be caught by one of the openings 0 c in the flange c of the casing, and as the bobbin is removed from between the clamping-arms c 0 these will yield to the In my improved bobbin-holder the force of the coiled spring 0 is exerted on the clamping-arms c to hold the bobbin and cause the same to rotate with the spindle. As the pressure is inward at two or more points, there is no tendency to split or otherwise injure the bobbin.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 7 1. In a bobbin-holder, the combination with the spindle and the bobbin, of a sleeve secured to the spindle, two or more clampingarms pivotally connected with the upper end of the sleeve, a Washer having a raised annular ring, a casing supported by the sleeve and a spiral spring interposed between the casing and the washer; whereby the clamping-arms are held in contact with the bobbin by the force exerted by the spiral spring to hold the bobbin, as described.

2. In a bobbin-holder, the combination with the sleeve 0, the casin g c secured to the lower end of the sleeve, the ring 0 secured to the upper part of the sleeve, the clamping-arms c c pivotally secured to the ring 0, the washer 0 having the raised annular ring (3 and the spiral spring 0 whereby the clamping-arms are operated and adapted to hold the bobbin,

as described.

3. In a bobbin-holder, the combination with the sleeve 0 adapted to be secured to the spindle, the ring 0' secured to the upper end of the sleeve 0, the casing c secured to the lower end of the sleeve 0 and provided with the flange c and the openings c 0 and the open ings c c in the sides thereof, of the crossplate a the arms of which extend through the openings 0 c in the sides of the casing, the coiled spring 0 interposed between the bottom of the casing c and the cross-plate a the washer c and the clamping-arms c c pivotally secured to the ring 0; whereby the clamping-arms yield on theinsertion of the bobbin and hold the base of the bobbin, as described.

In witness whereof I have hereunto set my hand.
