THREAD-TENSION DEVICE FOR LOOM SHUTTLES.
SPECIFICATION forming part of Letters Patent No. 546,677, dated September 24, 1895.
' Application filed February 23,1895. semi No. 539.323. (ModeL) To aZZ whom it may concern.-
Be it known that I, HERBERT W. OWEN, a citizen of the United States, residing at Millbury, in the county of Worcester and Oommonwealth of Massachusetts, have invented certain new and useful Improvements in Thread-Tension Devices for Loom-Shuttles, of which the following is a specification.
My invention relates particularly to a thread-tension device for loom-shuttles.
My improvement consists in a piece of wire bent into the required shape and secured to the frame of the shuttle or suitably mounted in a plate adapted to be secured to the frame of the shuttle, as will more clearly appear upon reference to the drawings, in which Figure 1 is a plan view of the shuttle and bobbin, showing my improved device attached thereto. Fig. 2 is a side view of the shuttle. Fig. 3 is an end view of the tension device mounted in the plate by which it is secured in place. Fig. 4 is a plan View of the plate and a top view of a part of the tension device, illustrating the manner in which the latter is attached to the plate. Fig. 5 is a bottom view of the plate and tension device seated therein. Fig. 6 is a longitudinal sectional view of the plate and tension device on the line 6 6, Fig. 4, looking in the direction of the arrow. Fig. 7 is a vertical sectional view of the plate and side view of the tension device on the line 7 7, Fig. 4., looking in the direction of the arrow. Fig. 8 is a perspective View of thetension device separated from the plate. Fig. 9 is a perspective View of the plate alone, showing particularly the means by which the tension device is secured in place. Fig. 10 is a view of the tension device made out of wire square in cross-section, also showing the adjustment of the thread in the tension .device when the same is in operation.
In Fig. 1, 1 is the shuttle-frame. 2 is the bobbin. 3 is the plate in which the tension device is mounted and may be secured to the shuttle-frame in any desired manner. It may conveniently be done by means of the screw 4. 5 is the tension device, which consists of a piece of Wire bent into substantially a U shape somewhere near its middle portion,with
may conform in shape to the coils.
each end bent at right angles to the middle portion and wound into a coil, the two coils being wound away from a common center, but in the same direction.
It is obvious that the members of the coils may be multiplied at pleasure and the tension upon the thread increased or diminished by increasing or diminishing the distance between the members. The members of the coils may be brought sufficiently near together to exercise a direct pressure upon the thread, which may be found desirable.
In the drawings I have shown two members 6 and 7 at one extremity and two members 8 and 9 at the other extremity, the former coil terminating at 10 and the latter terminating at 11.
It will be noted, upon referring to Figs. 8 and 10, that the outer coil terminating at 11 is raised at its lowest pointsomewhat above the immediately-adjoining coil, for a purpose hereinafter to be explained. I
. The tension device may be mounted in the supportingplate in any suit-able manner. The method which I prefer is illustrated in the drawings, in which the plate is shown provided with a saddle-piece 12, upon which the U-shaped part of the tension device is supported. The coils are sprung over the projections 13 and 14. into the hollow seat 15, which The upward projection 16 prevents the tension device from slipping off the saddle, and it is thus held securely in place. The end 17 of the supporting-plate is bent downwardly in order that the thread may not work out, and the angle 18 onthe under side of the supportingplate is rounded in order that the thread may be readily guided into the tension device without catching.
The modification in Fig. 10 shows the tension device made of wire square in cross-section, and is designed to catch any bunch which may be in the thread, thus breaking the latter and preventing any imperfect work in weaving.
The outer side of the supporting-plate may be rounded, so as to avoid any possibility of catching in the warp.
IIaving described the construction of my improved tension devicc,I will now indicate its mode of operation.
lhe thread from the bobbin is passed under the end 17 of the supporting-plate and is guided over the projecting ends 10 ll of the tension device until the thread occupies substantially the position shown by the horizontal line in Fig. 10.
Reference has been made to the fact that the outer coil terminating at 11 is somewhat higher than the lowest point of the next adjoining coil. This is to prevent the thread from working out of the tension device.
This device is also self-th reading, the th read being drawn off the bobbin when the shuttle leaves the box, and when the shuttle returns the thread is drawn under the end 17 of the supporting-plate and delivered to the tension device by passing over the upwardly-turned ends 10 and 1].
I do not confine myself to any special form of shuttle or bobbin, or to any particular means for securing the tension device to the shuttle-frame, or to any form of supportingplate, or to any particular size of wire for the tension device, or to any particular number of coils therein, or to any particular relative arrangement of the parts.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In combination with a shuttle-frame, a supporting plate and a tension-device of wire, consisting of two coils of a plurality of members each, said coils being formed in the same direction away from a common center, and having an intermediate portion adapted to be secured to the supporting-plate, the ends of said coils being free and adapted to receive a thread, substantially as shown and described.
2. In combination with a shuttle-frame, a supporting plate and a tension-device of wire, consisting of two coils of a plurality of members each, said coils being formed in the same direction away from a common center, and having an intermediate portion adapted to be secured to the supporting-plate, the ends of said coils being free and adapted to receive a thread, the outer member of the outer of said coils being higher at its lowest point than the next adjoining member, whereby the thread may be prevented from working out of the tension device, substantially as shown and described.
In combination with a shuttle-frame, a supporting plate and a tension-device of wire, consisting of a middle portion, bent substantially into a U-shape adapted to be secured to the supporting-plate, and terminating in two coils, of a plurality of members each, substantially at right angles with said middle portion, said coils being formed in the same direction away from a common center, the ends of said coils being free and adapted to receive a thread, substantially as shown and described.
