SHUTTLE EUR Looms. No. 569,721. Patented Oct. 20, 1896,
UNITED STATES ATsNT SHUTTLE FOR LOOMS.
SPECIFICATION forming part of Letters Patent No. 569,721, dated October 20, 1896. Application filed April 16,1896. Serial No. 587,797. (No model.)
To all", whom it may concern:
Be it known that I, THOMAS MORRISON, a resident of Williamsport, in the county of Lycoming and State of Pennsylvania, have invented certain new and useful Improvements in Shuttles for Looms; and I do hereby declare the following to bea full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in shuttles for looms.
It is the object of my invention to so construct said shuttle that it shall be effectual in all respects in the performance of its functions without in any manner injuring the fabric being woven or parts of the loom in conjunction with which the shuttle operates.
With these objects in view the invention consists in certain novel features of construetion and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.
In the accompanying drawings, Figure l is a view of the blank from which my improved shuttle-frame is made. Fig. 2 is a plan View of the complete shuttle-frame. Fig. 3 is a cross-section on the line of Fig. 2.
My improved shuttle-frame is made of a piece of sheet-steel of the best quality.
A represents the blank, consisting of a rectangular plate of thin sheet-steel and preferably having a slot a in its center. Each end of the blank is out so as to form three points l 1 2. The blank is then bent up on the lines 3 3, so as to form the rectangular open frame of the shuttle, said frame comprising abottom and sides 5 5. The point-s l l 2 at the respective ends of the frame are brought together and brazed to form the pointed ends of the shuttleframe. The brazed joints between the meeting edges of the points l l are slightly rounded and made perfectly smooth.
Between the sides 5 5 a brace G is located near one end of the frame, the sides of the frame at the other end thereof being braced by the transverse pins or bars with which the spool-holder is connected. The edge 7 of the brace is curved so as to be out of line with the sides of the frame, and the edges of said sides 5 5 are slightly rounded, so as to avoid all possibility of the warp-threads being out by them.
It will be observed that those portions of the sides of the frame which constitute parts of the pointed ends of said frame are so shaped that their edges S will be beveled or inclined and said pointed ends will therefore be nearly conical.
INithin the extremities of the pointed ends of the frame steel blocks or tips 9 are brazed, and the upper faces of said blocks or tips will be made smooth and exactly iush with the edges S of the frame, so as to expose no projection whatever which can catch or engage the Warp-threads. l
In order to further guard against the engagement of the warp-threads by the inner ends of the blocks or tips 9, said inner ends Will be beveled or rounded, as shown at l0.
By making the Walls of the frame thin the amount of frictional contact of the shuttle with the warp-threads and parts of the loom will be reduced to a minimum. Another advantage of thin walls of the frame is that the space within the frame will be enlarged, thus permitting the use of a large amount of thread on the spool when the latter is first inserted into the shuttleframe. My improved shuttlc-frame is a mere shell of steel and is open from tip to tip, and by thus making the frame open the frictional surface is still further reduced.
The shuttle-frame cannot chip, splinter, or break, and there are no exposed points or connections and consequently nothing to catch or injure the warp-threads.
My improvements are very simple in construction and are effectual in all respects in the performance of their functions.
Slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope, and hence I do not wish to limit myself to the precise details herein set forth; but,
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
l. A shuttle for looms constructed of sheet metal, the blank of which the shuttle is formed being made in a single piece and having V- shaped notches eut in its ends and the blanl;
1o end of the shuttle and secured transversely across the interior of the shuttle, substantially as set forth.
In testimony whereof I have signed Juhis specicaton in the presence of two subscribing Witnesses.
THOMAS MORRISON.
