West, Gadsden, Ala., assignor of one-I half to Carl W. Jones, Gadsden, Ala. Application April 15, 1937, Serial No. 137,113 3 Claims. (Cl. 139—187) My invention relates to releases for ?y shuttle type looms and the improvement of which is fully set forth in the following speci?cation and claims. The general object of the invention is to pro 5 vide means whereby the shuttle tension means are released just before the shuttle leaves the box, such means including a roller carrying mem ber attached to an arm on the tension shaft and a pivoted cam member having means for sup 10 porting it from a part of the frame of the loom. In order that the principle of the invention may 15 shaped jack lever, the vertical part of which is shown at I9 and the horizontal part at 2!], the pivot 24 passing through the junction of the two parts and through the lower ends of the com panion parts of the bracket. The top part of the bracket has a slot therein which communicates be readily understood, I have disclosed a single with the space between the depending parts and the part I9 of the jack extends through the slot and the upper end of this part I9 has the cam head I8 thereon. A spring 2| engages a part of 10 the bracket and the outer end of the part 20 and tends to hold the jack in tilted position as embodiment thereof in the accompanying draw ings and a break down generally of its several shown in Figures 1 and 3. The parts are so arranged that as the lay nears parts. the end of its rearward movement the roller will 15 engage the head I 8 of the jack and this will cause In the drawings:Figure 1 is a fragmentary View partly in trans verse section and partly in elevation showing the end of the loom and a rock shaft mounting with 20 part of the invention connected to the protection rod and the other part to the loom end. Figure 2 is a View partly in front elevation and partly in section taken on the line 2—2 of Fig ure 1 looking rearwardly. Figure 3 is a detail view in side elevation show 25 ing the jack, its mounting and operating spring. Figure 4 is a view in top plan partly in section showing the head of the jack in dotted lines and the head support projecting through its mount 30 mg. Figure 5 is a perspective view of the roller shaft mounting with a slot in it for adjustment. In these drawings, a part of the frame of the loom is shown at I, the sword at 2 and the lay 35 at 3. A tension or presser ?nger is shown at 4 which is connected with the spring actuated rock shaft 5, the binder being shown at ‘I for applying pressure to the shuttle 8 in the box, a portion of which is shown at 9. All of these parts are of 40 the well known type and form no part of my invention. In carrying out my invention I attach a bracket H to an arm 6 on the shaft 5 and said bracket has an elongated slot therein for receiving the 45 bolts III which also pass through the arm 6 so that the bracket is adjustably connected with the arm. A threaded shank I3 is threaded in a- hole I2 in the outer end of the bracket and a nut Ill holds the shaft in adjusted position in the bracket. 50 The lower end of the shaft carries a forked mem ber I5 and a roller I1 is carried by said member. A bracket 22 is adjustably connected to a part of the frame I by a bolt passing through a slot 23 in the bracket and said bracket has a pair of 55 depending parts between which extends an angle the shaft 5 to rock in a direction to cause the arm 4 to release the tension on the shuttle in the box so that the shuttle can easily leave the box. On the forward motion of the lay the jack will tilt 20 against the action of its spring, when engaged by the roller, as shown in dotted lines in Figure 1 and this prevents damage to the loom parts should the shuttle fail to box for any reason. As will be seen in the normal position of the 25 jack the head I8 slopes upwardly and forwardly with the part I9 at a slight inclination and the forward end of the head is beveled as shown more particularly in Figure 8. It is thought that the construction, operation, utility and advantages of this invention will now be quite apparent to those skilled in this art with out a more detailed description thereof. The present embodiment of the invention has been described in considerable detail merely for the purposes of exempli?caticn and it is to be understood that modi?cations of details described may be resorted to within the scope of the ap pended claims since in actual practice it attains 40 the features of advantage enumerated as desir able in the statement of the invention and the above description. I claim: 1. In combination with the shuttle tension 45 means of a loom including- a tension shaft, a bracket extending forwardly from the shaft, a roller carrying member depending fromv the bracket, a second bracket supported from the loom frame, a cam head having a shank depending 50 therefrom, the lower end of the shank being piv~ otally supported in the bracket, yieldable means for holding the shank in a tilted position with the shank extending upwardly and rearwardly and with the head sloping upwardly and forwardly, 55 2 2,114,949 said head being engaged by the roller during the 3. In combination with the shuttle tension movement of the loom parts. 2. In combination with the shuttle tension means of a loom including a tension shaft, and means of a loom including a tension shaft, an arm connected with the shaft, a bracket, means for a?ustably connecting the bracket with the an arm on the shaft, a bracket adjustably con arm, a shaft depending from the bracket, means nected with the arm, a depending shaft connected end of the shaft, a second bracket adjustably con for adjustably connecting the shaft with the bracket, a roller at the lower end of the shaft, a second bracket connected with the loom frame, a nected with the loom frame, a cam head having bellcrank member pivoted in the second bracket with the bracket, a roller supported at the lower 10 a depending shank, means for pivotally connect ing the lower end of the shank in the second bracket and means. including yieldable means for permitting the shank to tilt when engaged by the roller on the forward movement of the lay, the 15 head of the shank causing upward movement of the roller carrying parts when said roller engages the head on the rearward movement of the lay. and including an upstanding part having a cam 10 head thereon, a spring having a part engaging the horizontal portion of the bellcrank and a part of the bracket for permitting movement of the bell crank in one direction, parts of the bracket pre venting movement of the bellcrank in an opposite 15 direction when engaged by the roller.
