TENSION DEVICE FOR WEAVING-MACHINES.
Specification of Letters Patent.
Patented Dec. 24, 1918.
Application filed March 19, 1918. Serial No. 223,291.
To all whom t may concern:
Be it known that I, JOHN O. I-IAYns, a citizen of the United States, and' a resident of the city of Evanston, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Tension Devices for Weaving-Machines, of which the following is a specification.
My invention relates to improvements 1n tension devices for weaving machines, and has for its object the provision of an 1mproved device of this character especially adapted for imparting resistance or tension to comparatively heavy and stiff threads or strands employed in weaving.
The invention consists in the combinations and arrangements of parts hereinafter described and claimed.
The invention will be best understood by reference to the accompanying` drawings forming a part of this specication, and in which:
Figure 1, is a plan view of a weaving shuttle equipped with a tension device embodying my invention,
Fig. 2, is a side view of the same, and
Fig. 3, an enlarged section taken on line 3 3 of Fig. 1.
The preferred form of construction, as illustrated in the drawings, comprises the usual shuttle for carrying the usual bobbin or thread reel 5 therein, and having the usual thread 6 wound thereon and passing outwardly throughthe usual sleeve or eye 7 in the side of the shuttle. These are all old and well known parts of a weaving shuttle and constitute no part of my present invention, except in so far as they coperate with the tension device hereinafter set forth.
This tension device comprises a friction plate 8 removably secured in place in the shuttle just forward of the bobbin 5 by means of a screw 9. The plate 8 is provided on each side with an upstanding ear 10 and a supporting rod or pin 11 is mounted in said ears. A tension device 12 made of spring wire bent into substantially U-form is mounted on the pin 11 to bear against the tension plate 8. The eXtreme end or bend 13 of this tension device is made straight to rest upon the friction surface of plate 8, the portions 14 immediately joining the ends of the portion 13 are outwardly bent, as shown, to closely approach or contact with the sides of the shuttle and coiled spring portions 15 are formed in the sides of said tension device and are mounted on pin 11. The extreme ends 16 of the sides of said tension device are turned outwardly to form securing pins, adapted to be inserted in holes 17 formed in the ears 10 for the purpose and whereby the tension in the spring coils 15 may be readily adjusted as desired.
In use, the thread 6 from the bobbin 5 is passed over plate S under the spring device 12, and is thus frictionally held or retarded to introduce tension therein. The arrangement as shown, permits of considerable free lateral travel of the thread 6 and the bends 141 prevent disengagement thereof with the tension device.
While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I
therefore, do not wish to be limited to` the precise details of construction set forth, but desire to avail myself of such variations and modications as come within the scope of the appended claims.
Having described my invention, what I claim as new and desire to secure by Letters Patent isz- 1. The combination with a weaving shuttle of a tension plate secured in said shuttle immediately forward of the bobbin therein; a supporting pin mounted on said plate substantially parallel with the face thereof; a spring tension device consisting of a spring wire substantially in U-form, with the end of its bend resting fiat on said plate, coiled springs being formed in the sides thereof and mounted on said pin; and means for locking the eXtreme ends of said wire in position to hold said bend against said plate, substantially as described.
2. The combination with a weaving shuttle of a tension plate secured in sai-d shuttle immediately forward of the bobbin therein; ears at the edges of said plate; a supporting pin mounted in said ears substantially parallel with the face of said plate; and a spring tension device consisting of a spring wire substantially in U-form, with the end of its bend resting fiat on said plate, coiled springs being formed in the sides thereof and mounted on said pin, the eXtreme ends thereof being outwardly turned to form locking pins, there being a plurality of holes in said vears to receive said locking pins to adjust .3. The combination with a weaving shut' tle, of a tension plate secured in said shuttle immediately forward 0f the bobbin therein; ears at the edges of said plate; a supporting pin mounted in said ears substantially parallel with the face of said plate; and a spring tension device consisting of a spring wire, substantially in U-form with the end of its bend resting flat on said plate, the adjacent portions of its sides bent outwardly to l closely approach the sides of the shuttle,
Copies of this patent may be obtained for treme ends thereof being outwardly turned to fo'rm locking` pins, there being a plurality of holes on said ears to receive said locking pins to adjust the tension in said Spring coils,
substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JOHN O. HAYES.
