RING-SPINNING MACHINE.

SPECIFICATION forming part of Letters Patent No. 732,526, dated June 30, 1903.

Application filed December 27, 1902. $erialN0.136,786. (No model.)

To all whom it may concern.- Be it known that I, NAROISSE N. S. DAU- DELIN, a citizen of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Ring- Spinning Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to thefigures'of reference marked thereon, which form a part of this specification.

This invention relates to spinning and twisting frames; and its object is to relieve the yarn from the strain which is caused by the short distance between the ring-traveler and the guide-wire on the thread-board when the ring-rail is atthe highest point of the wind,

the shortness of this distance causing the yarn to turn at a sharp angle where it passes through the guide-wire and ring-traveler. This trouble is aggravated when a large ring is used. I accomplish this result by hinging the thread-board and providing means for automatically lifting it at the proper time in the travel of the ring-rail, as hereinafter set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a portion of a cross-section of a ring-spinning frame equipped with my invention. Fig. 2 is a rear elevation of the same looking in the direction of the arrow in Fig. 1. Fig. 3 is a modification.

The machine shown is of the usual construction, the yarn passing through the rollers 1 and then being led through the wireguide 2 on the thread-board 3, and thence to the traveler on the ring-rail 4, which is moved up and down by a rock-arm 5 on one of therock-shafts 6 of the machine. The weight of the moving parts is counterbalanced by a weighted arm 7 on said shaft. The threadboard is hinged to the roller-beam at 8, and secured to it, preferably on its upper side, is a lever 9, which runs back between the standards 10, that support the rollers. An upright rod or wire 11 is attached to the end of the lever by a joint permitting entire freedom of movement, such as a slot 12 in the lever,

through which the wire passes' Above-the lever the wire is provided with a head or nut 13, and said wire extends down to an arm 14, secured 011 the rock-shaft 6, the connection between the wire and arm being by means of a lost-motion device. In the drawings the wire is shown passing through a hole in the arm, below which it has an adj us table stop 15, such as a nut meshing with screw-threads out in the Wire.

The operation of the device is as follows: At each actuation of the rock-shaft to lift the ring-rail the arm 14 is depressed, and when the travel of the ring-rail becomes so great as to cause too sharp an angle of the thread at the thread-board guide the arm strikes the stop and pulls down the wire, thereby tilting up the thread-board, as shown in dotted lines in Fig. 1, and thus relieving the strain on the thread. The adjustability of the stop provides' for the accomplishing of this result at any given point in the travel of the ring-rail.

During the rest of its travel the arm moves up and down freely on the wire without affectsecured thereto, a rock-arm on a rock-shaft of the machine, and a single element directly connecting said lever and arm and providing for a certain amount of lost motion;

2. In a ring-spinning machine, the combination with a hinged thread-board, of a lever secured thereto, a rock-arm on a rock-shaft of the machine, a Wire passing through the lever and the arm, and an adjustable stop on said wire below the arm.

In testimony whereof I affix my signature in presence of two Witnesses.
