TENSION DEVICE FOR LOOM SHUTTLES.
No. 479,084, v Patented July 19,1892.
UNITED STATES MICE.
HENRY BARDSLEY, OF PHILADELPHIA, PENNSYLVANIA.
TENSION DEVICE FOR LOOM-SHUTTLES.
SPECIFICATION forming part of Letters Patent No. 479,084, dated July 19, '1892. Application filed December 29, 1891. Serial No. 416,442. (No model.)
To aZZ whom it may concern;
Be it known that I, HENRY BARDSLEY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new anduseful Improvement in Tension Devices for LoomSh uttles, of which the following is a specification.
My invention relates to power loom-shuttles and to that part known as the weft-tension.
The object of my improvement is to provide a simple adjustable weft-tension for power loom-shuttles, which tension may be adjusted to suit different kinds of yarn and insure a perfect selvage on the cloth to be woven; and it consists in the combination of a frictionclam p with regulating-screw and spiral spring and a pivoted tube so mounted in the shuttle as to weight the weft between the cloth selvage and shuttle-tension, as is illustrated in the accompanying drawings, making a part of this specification, in Which Figure 1 is a top view of a loom-shuttle, showing my improvements. Fig. 2 is a longitudinal central section of Fig. 1. Fig. 3 represents in detail the weighted tube and parts for mounting it in the shuttle. Fig. 4 represents the weft-friction tension in detail, showing the parts required to mount it in the shuttle.
Similar letters refer to similar parts throughout the several views.
A represents the body of the ordinary loomshuttle; B, the bobbin carrying the weft-yarn. This bobbin is mounted on aspindle or skewer in the ordinary manner.
a is the tension-plate. This plate should be made of steel and hardened.
b is a steel pin or bar. This bar should be made of steel and hardened.
(l is a metal pin, in which is cut a slit e. At the other end is out a screw-thread and notch for a screw-driver.
f is a steel spiral spring, the ends of the wire forming this spring. One end is bent across the center of the coils. The other end is bent out from the coils, as shown at f.
g represents the swinging tube. This tube is made in form of the letter T. The ends of the arms are center-pointed and a hole passes through the body, as shown by dotted lines.
The tube part should be made of steel and hardened.
h represents cup-centers for hanging the swinging tube in the shuttle. These cup-centers are made of steel and hardened. They have a screw-thread out on them and at one end a notch for a screw-driver. The other end is countersunk to the shape of the center points on the arms of tube g.
In putting the tension-plate a and bar I) in the shuttle they are so placed that the bar I) will be a little below the line of the weft as it is drawn off the bobbin or cop. The tensionplate a is hung on the slotted pin (Z, on which is also hung the coiled springf, with the end of the wire that crosses the coils inserted in the slot e, the end f resting on the plate CL. The pin d is made to fit tight in the body of the shuttle, so that it will remain in the position it is turned by the screw-driver. The tube 9 should be hung so that the hole in the tube will be in line with the shuttle-eye and tension-clamp, as shown in Fig. 1. The weft is drawn through the tube and tension-clamp by a weft-hook, such as used to draw the weft through the sh uttleeye, and after drawing it through the clamp and tube it is drawn through the shuttle-eye. Thetensiou is then adjusted by taking a screw-driver and turning the pin (Z, which will tighten or slacken the coils of the springfand regulate the pressure of plate a on bar I), as they will the tension on the weft which passes between. The shuttle is now ready for use, and as the shuttle is picked from one side to the other of the loom the weft will be drawn off quick and the swinging tube would fly up above the top of the shuttle; but to prevent this I place a wire S across the shuttle above the tube g, and this prevents it flying out of the shuttle and breaking the warp ends. The shuttle when striking the picker sometimes rebounds and makes the weft run out slack. The swinging tube will act on this slack weft. It will fall to the position shown in section, Fig. 2, and draw the slack weft tight and make a good selvage.
I do not confine myself to the form of parts shown or materials used, as both may be varied.
Vhat I claim as new, and desire to secure by Letters Patent, is
A loom-shuttle having a tension device consisting of a bar I), a plate a, mounted on the adjusting screw or pin (1 and held in contact with the bar I) by the coiled spring f, one end of which rests in the slot 6 of the pin (1, whereby the pressure of the plate a may be regulated, the said screw or pin (1 and spring f, and a swinging tube g, through which the weft passes, and a stop 8 to limit the upward movement of the tube, the tube acting as a 10 drag to take up the slack in the weft, substantially as shown and described.
