At its movement of the movable jaw, the valve is opened other end, the trigger carries a pin 23 to the oppoto discharge a small amount of adhesive to be site ends of which are pivotally connected the taken up by the ends of the strands between the ends of links 24. The other ends oi the links jaws. The movement of the movable jaw away are pivotally attached to the sides of the movable jaw I l by screws 25. With thisarrangement, when the trigger 22 is swung, so 'that its free end approaches the hand grip IE, it moves the movable jaw ll away from the stop l6 and, in the initial part of its movement, the jaw is rocked by the action of springs I 8 about the line of intersection of surface I! with the face l2 of jaw Ill, until the face l3 of jaw ll engages the face l2 of jaw Ill. The movable jaw then moves over the face of thestationary jaw to the limit of move ment of the trigger. When the trigger is released,

' the springs l8 return the moveable jaw H along the face of the stationary jaw l0, until jaw I I becomes overbalanced along the. line of intersection of surface I! with face l2, after which jaw ll rocks counterclockwise to engage surface I! and abut stop It.

A receptacle 26 for adhesive is mounted on one of the jaws and, in the construction shown, the receptacle is carried by the movable jaw II. The receptacle comprises a bushing?! seated in a recess in the top of jaw II and closed at its outer end by a cap 28 threaded on the end of the bushing. A small recess 29 formed in jaw ll extends below the end of bushing 21, and an outlet opening is formed through jaw II from the bottom of recess 29 to the face l3. The outlet is normally closed by a valve 30 mounted within the receptacle on one end of a leaf spring 3|, the other end of which is secured by a screw 32 to the bottom wall of the recess, in which bushing 21 is seated. The valve 30 has an end 33 smaller than the outlet and, when the valve is closed, as shown in Fig. 4, the end 33 extends beyond face I3. The jaw III is provided with a longitudinal channel 34, which, is of two different depths, with its shallower portion extending from about the middle of the jaw to the inner end thereof. This channel is in position to receive the projecting end 33 of valve 30.

A pair of cooperating cutting elements are mounted on opposite sides of one of the jaws in such position that one element of each pair is moved relative to the other to effect a cutting action, when the movable jaw rocks to bring its face l3 in contact with face I2 of the stationary jaw. In the device shown, the cutting elements are mounted on the sides of the stationary jaw l0 and each pair comprises a fixed plate 35 secured against the side face of the jaw and a knife member 36 pivotally mounted on the side of the jaw to overlap its associated plate 35. The knife member has a cutting edge 36a on its lower surface. Plate 35 projects beyond the face I2 of jaw IO to a slight extent and there is a notch 31 serving as a strand stop in the projecting portion of the plate at the outer end thereof. The knife member 36 also projects upwardly above the surface l2 of jaw l0 and its upper edge lies within a longitudinal groove 38 formed along the side edge of the bottom of movable jaw I I. In the use of the new device to connect the ends of a pair of yarns, the operator holds the device in one hand and inserts the ends of the yarns between the two jaws, as indicated by the lines A, B (Fig. 3); In inserting the yarns, the operator placesthe yarn A so that its free end A projects out beyond the jaws at one side and the yarn engages the stop 31 at the opposite side of the jaws. Yarn B is then placed between the jaws in contact with the other stop 31 and with the free end B projecting out from between the jaws. In this position, the yarns cross at the middle of the stationary jaw above the top of channel 34. The operator then moves t g 22 clockwise by his finger and this causes the movable jaw II to move away from stop ii. In the initial part of its movement jaw ll rocks clockwise to grip the ends of the yarns between faces l2, l3 of the jaws and, at the same time,

the knives l6 swing along the edges of plates 31 and sever the portions of the free ends of the yarn projecting beyond the cutting elements. As jaw H approaches the end of its rocking movement, the projecting end 33 of valve 30 engages the bottom of the shallowerportion of channel 34, and the valve is pushed out of the outlet, so that a small amount of adhesive is discharged upon the yarns at the point of crossing. As the jaw ll moves along the face of jaw ID, the ends of the yarns between the jaws are rolled together. Shortly after the'movement of jaw ll along jaw It) begins, the end 33 of the valve enters the Upon release of the trigger, jaw H is moved back rapidly by the action of springs I8 and the yarns are rolled together in the reverse direction. Ultimately jaw ll swings away from jaw III to release the connected yarns and they are removed from the device. In the backward movement of jaw II, the end 33 of the valve momentarily engages the bottom of the shallower portion of channel 34 and opens the valve.
