AUTOMATICALLY THREADING SHUTTLE. APPLICATION FILED APR. 4. 1919.

HUDSON W. I-IAKES, OF MILLBURY, MASSACHUSETTS.
AUTOMATICALLY-THREADING SHUTTLE.
Application filed April 4, 1919.
To all whom it may concern:
Be it known that I, HUDSON 1V. HAKES, a citizen of the United States, residing at Millbury, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Automatically-Threading Shuttles, of which the following, taken in connection wit-h the accompanying drawings, is a specification.
My present invention relates to shuttles, and especially to those adapted for use in looms in which the shuttle is automatically provided with a supply of filling while the loom is running, and it has for its object to provide effective means for controlling the thread or filling as it passes from the bobbin to the delivery eye of the shuttle, and this object among others is accomplished by the construction hereinafter described. the novel features being setforth in the appended claims.
Referring to the accompanying drawings,
Figure 1 is a plan view of the delivery end of the shuttle containing my present invention.
Fig. 2 is a side view of my improved threading device illustrating its positionin the shuttle, which is represented in broken lines.
Fig. 3 is a rear view of the threading device detached from the shuttle.
Fig. 4 is a sectional view on the plane of the broken line 4-4, Fig. 3.
Fig. 5 is a top View of that portion of the threading device which is preferably formed of cast metal.
Fig. 6 is a perspective view of asheet metal insert or bushing of the threading device.
Similar reference characters refer to similar parts in the different figures.
Referring to the accompanying drawings 1 denotes a portion of the shuttle having an opening 2 to receive a bobbin 3. The delivery end of the shuttle is provided with an opening or eye 4 for the delivery of the filling thread 5. The threading dev ce represented in plan view at 6 in its posit on in the shuttle is formed in two parts, in the present instance, for the convenience of manufacture; one part preferably made of cast metal, is represented in plan view in Fig. 5, and is adapted to be held in a recess formed in the shuttle, the second part preferably formed of sheet metal is represented in perspective view in Fig. 6, and adapted Specification of Letters Patent.
Patented Jan. 13, 1920.. Serial No. 287,478.
to be inserted as a bushing in the portion shown in Fig. 5. The cast metal portion of the threading device, as represented in Fig. 5, is similar in its construction to the threading devices now in common use, and 1s provided with a flange 7 overhanging the dehvery opening and terminating in a beak 8 extending beneath a flange or shield 9. The threading device is provided with a longitudinal opening 10 adapted to receive a bushing 11, preferably formed of sheet metal, shaped to form a bottom 12 and upturned parallel side walls 13, 14. Upon the tops of the side walls 13, 14 are formed the bent flanges 15 and 16 oppositely inclined. The flange 15 has its rear edge convex, as shown at 17, Figs. 1 and 4. and its front edge concave, as shown at 18, Figs. *1 and 4. The flange 16 has its rear edge concave, as shown at 19, Figs. 1 and 4, and its front edge convex as shown'at 20. The sheet metal bushing 11 is inserted in the recess 10 and is held in place by a prong 21 and a similar prong 22 which are forced into openings or slits in the cast metal piece. shown in Fig. 5, and attached thereto by solder. The tips of the flanges 15 and 16 stop short of the opposing side walls of the threading device so the filling thread 5 when it is drawn taut over the tips of the flanges 15 and 16 is capable of sliding over the tips of the flanges and entering the space between the side walls 13 and 14 which forms the thread channel.
When the filling thread is drawn through the space between the beak 8 and the shield 9 it passes over the beak and around the edge of the horn 23. As the filling thread slips off the end of the horn 23 in its passage through the delivery opening 4 it is drawn around the steel pin 25. Between the lower end of the horn 23 and the pin 25 I form a series of notches 26. The concave edges 18 and 19 are spaced so that a loop in the filling thread caused by ballooning. even if the thread should pass the flange 15, will be caught by the concave edge 19 of the flange 16. and any loop which results in the escape of the filling thread from the flange 16 will be caught by the concave edge 18 of the flange 15. As soon as tension is applied to the filling thread the loops which may be formed therein will be drawn over the curved flan es into its normal position in the thread channel.
I have described the construction of the bushing 11 as of sheet metal as facilitating the manufacture of the threading device, but I do not wish to confine myself to a sheet metal insert or bushing. The flanges 15, 16, serve as deflectors to deflect the filling thread over their tips into the thread channel between the vertical walls 13 and 14a The sheet metal bushing has the side walls 13 and 14 cut away or beveled, as shown at 27, 28, Fig. 6, in order to provide a clear space for the passage of the filling threads over the tips of the flanges. In order to engage the prongs 21 and 22 in the cast metal block shown in Fig. 5, a slit 29 is made in the cast metal block to receive the prong 21, and the prong 22 is bent upright to allow the bushing to enter the cast metal block, and an opening is formed in the block into which the prong 22 is forced, and the opening is subsequently filled with solder. The notches 26 prevent the filling thread from being drawn back over the horn 23.
I claim,

An automatically threading device for a loom shuttle having a single longitudinal thread passage, an inclined deflecting flange extending over the thread passage at one end thereof, and a second oppositely inclined deflecting flange extending over the thread passage at its opposite end, with said deflecting flanges spaced apart to provide a clear space between the transverse edges of said flanges. v 2.
