Figs. 7 and 8 are perspective views showing the adjusting screw and the opening in the yarn guide with which it cooperates.
Referring first to Fig. 1, the invention is shown for purposes of illustration as being embodied in a loom shuttle S, the body I of which provides a chamber 2, extending longitudinally of the shuttle for the reception of a bobbin 3. The butt of the bobbin 3 is held at one end of the chamber 2 bya suitable gripping device 4, and the tip of the bobbin extends to a point adjacent the :opposite endof the shuttle chamber 2, so

that the yarn Y may be unwound from the bobbin and drawn through a yarn tensioning device before leaving the shuttle eye E. e
f The adjustable yarn tensioning device of the 5 present invention is embodied in a yarn guide5 whichis generally in the form of a block 6 having parallel sides that are received between the walls of a slot 1 formed in the shuttle body I, adjacent to the tip of the bobbin 3. The yarn 10 guide 5 is shown in Figs. 2 3 and4 as having been removed from the shuttle S, with the guide being drawn on an enlarged scale, as compared to its actual size, in order to-better show the construction of the parts entering into the adjustable tensioning device of the present invention. I As best shown in Figs. 1 and 4, the guide block 6 provides'a yarn' delivery channel 8 in line with the axis of the bobbin 3, for the passage of the yarn Y, and this channel 8 leads into a recess 9 formed in the block 6 for receiving a pair of vyarn tension plates Ill. The lower ends of the plates l0 are mounted freely on a pin H extending transversely of the block 6 across the recess 9, and the upper ends of the plates 10 are freely received in openings 1 2 provided on opposite sides of the yarn delivery channel 8.
By reason of their relatively loose support within the recess 9 of the block 6, the plates I0 are adapted to receive the yarn Y between them,
when the yarn is led from the bobbin 3 and passed downwardly through the channel 8. The 7 object of the present invention is to provide adjustable means for exerting pressure on the plates II) which tendsto hold them together, in order that a frictional force will be appliedto the yarn Y, as it is drawn through the shuttle -eye ,E, to set up and maintain a desired degree oftension in the yarnpas the shuttle 8 moves back and forth during operation of the loom; 40.I i'For' this purpose, each plate ID has associated therewith anadjusting screw l3, which as best sho'w'n in Fig. 4, is adapted to be received within lathreaded opening l4 provided in the side wall lot. the recess 9 in theblock 6. n The inner end of the screw' [3 provides aseat l5 for the reception of a spring Hi, the outer end of which bears on a tension plate l0, and obviously the position of the screw l3, with respect to the threaded opening HI,v will determine the amount of pressure exerted by the Spring Hi. It will be evident from a consideration of Fig. 4 that the two plates l0 are held in yielding engagement with each other by the oppositely disposed springs l 6, so that the frictional force applied to the yarn Y, while heing drawn between the plates 10, will be deter-v
