i This invention relates to improvements in shuttles and `more particularlyto improvements in means'for tensioning the yarn in the j shuttles. i The principal object of the inventionis to provide a tensioning device o'fnovel and improved character and of great "simplicity of form. i Another objectof the inventionis to providea deviceof the stated character which `may be readily and accurately adjusted to regulate the tension of the yarn.
Another object of the invention is to proj vide a novel tensioning means which is ca- 1'5 pable of removing lint and flies from the yarn passing through the shuttle.` f
The invention further resides in certain features and details of construction setforth 1 hereinafter and shown in the'accompanying drawing, in which:
Figure 1 is aplan view of oneA end of a shuttle showing su'licient of the parts to 1 afford an understanding of the present invention;
Fig. 2 is a front elevation View of Fig. l;
Fig. 3 is a transverse View in section on line 3--3,Fig.1;` j j Fig. i is a longitudinal view in section on line 4 4, Fig. 1; j
Fig. 5 is a view in perspective showing the tension member completely removed from the shuttle; and
Fig. 6 is a view in perspective from a different angle of the disclosure of Fig. 5.
Referring to the drawing the numeral 1 represents the body of a shuttle which may be of standard form. rfowards one end and in the interior thereof the shuttle comprises a yarn tensioning device which, in a preferred form comprises a guide member 2 provided with a longitudinally extending threading groove 3 having an overhanging guard 4 eX- tending thereover at least in part. The groove 3 in the present instance communicates with an underlying longitudinally disposed bore 5 in which the yarn normally travels throughthe tension member. The guide body is further provided with a transverselyV disposed thread groove 6 extending outwardly of and connecting with the longitudinally 1931. Serial No. 546,862.
disposed yarnbore 5. Furthermore to e'ectively guide the thread through the tensioning device, that portion of the guide body overhanging the transverse yarn groove 6 is formed in a depending hook element 7- intermediate which, and the groove `6, the yarn is arranged to pass. The guide 2 is provided with a `transversely disposed `bore 8 suitably arranged therein for facilitating the securing thereof in the shuttle body 1,` as shown in Figs. 1 and 2, by` means of a threaded screw element 9. i i .i A, j
To effectively and readily tension theyarn pas-sing through the member 2, We provide a resilient wire element 10 in the novel-form shown in Figs. 5 and 6 of the drawing. rlhe tension element 10 isprovided in the preferred form with a loop 11 which embraces a depending lug 12 on Vthe lower face of the guide body 2, for securing the said element 10 thereto. The said elementlO further comprises integral arms 13,13@ extending rearwardly from the loop 11 and passing in parallel adjacent relation along the rear ,face of the'guide body 2. At the upper portions thereof the said arms 13, 13a are curved outwardly with respect to the parallel upstanding portions thereof and downwardly to form loops lying `flat against the rear face and subsequently pass about the vertical rear edges of the body and along the side faces thereof, the terminal portions engaging the bottom edges at each side of the lug 12. The
`tension in the yarn is effected by arranging the yarn to pass intermediate the upstanding adjacent portions` 13, 13al of the tensioning element 10. The yarn in practice also extends throughthe longitudinal bore 5 and intermediate the depending `hook 7 and the yarn groove 6. f
By means of the device described above, the tension placed upon the yarn as it passes between the cooperating relatively adjustable and opposed `portions 13, 13a of the tension element 10, may be adjusted as desired by Amanually moving the said opposed portions relatively closer or` further apart with respect to each other. In providing a tension adjustment of simple and novel form as in the present case, we not only are able to efsuch as described above, are further removed from the yarnV by means of an obliquely disposed felt strip 14, removably positioned in the slot 15 in the guide body 2, and extending a sufficient distance inwardly of the longitudinal bore 5.
It is apparent that the invention is capable of other embodiments than that illustrated and it will be understood that no limitations are imposed other than set forth in the appended claims.
We claim:
1. In a shuttle for yarn a tensioning device comprising a guide body having a longitudinal yarn bore extending therethrough and a transversely disposed yarn groove connecting withand extending outwardly from said bore, a depending lug on said tensioning member, and a tensioning wire extending over a portion of said device and about said lug, the said wire having relatively opposed portions adjacent the rear end of the bore intermediate which the yarn is arranged to pass to regulate the tension in the yarn.
2.l In a shuttle for yarn, a tensioning device comprising a guide body having a longitudinal guide bore extending therethrough and a transversely disposed groove connecting with and extending outwardly from said bore, a depending lug on said guide body, and a tensioning wire extending over a portion of said device and about said lug, the said wire having relatively opposed upstanding arms adjacent the rear end of said bore intermediate which the yarn isfarranged to pass and which cooperate to regulate the tension therein.
3. In a tensioning device comprising a guide body having a depending lug on the bottom surface thereof, a tensioning element having a loop formed therein and embracing said lug, integral arms extending rear- Vwardlyof said loop and passing in parallel relation along the rear face of the guide body, the upper portions thereof being curved outwardly with respect to the parallel upstand- 'ing portions and downwardly to form loops lying fiat against the rear face of the body, and the terminal portions of said element passing about the vertical rear edges of the body, along the side faces thereof, and engag: ing the bottom edges of said body.
4. In a shuttle for yarn, a tensioning device comprising a guide body having a yarn bore extending therethrough, a depending projection on said guide body, and a tensioning wire embracing the outer surface of said body and the projection, the said wire having relatively opposed portions overlying one face of the guide and the bore intermediate which the yarn is arranged to pass to regulate the tension therein.
5. In a shuttle for yarn, a tensioning device comprising a body having a longitudinal bore extending therethrough, a projection on said body, and tensioning means embracing the outer surface of said body and the projection, the said means including relatively opposed upstanding arms adjacent the rear end of said bore intermediate which the yarn is arranged to pass to regulate the tension therein.
6. In a shuttle for yarn, a tensioning device comprising a body having a longitudinal bore extending therethrough, a projection on said body, and tensioning means extending over the outer surface of said device and said projection, the said means including relatively opposed upstan'ding-arms overlying one face of the guide and one extremity of the bore intermediate which the yarn is arranged to pass to regulate the tension therein.
