HANDLE FOB THROWING BOWLING-BALLS.

Specification of Letters Patent.

Patented July 22, 1913.

Application filed September 27, 1912. Serial No. 722,683.

To all whom 2'25 may concern:

Be it known that I, J 01 m 7. HYATT, a citizen of the United States, residing at 724 Ridge street, Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Handles for Throwing Bowling-Balls, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The present invention relates to a handle for throwing bowling balls and analogous objects, and the purpose of the invention is to permit the operator to throw the handle with the object and to automatically disengage the handle from the object by such act of throwing. This secures the detachment of the handle from theobject without any voluntary or conscious effort on the part of the operator, which would be likely to confuse him when discharging the ball.

The invention therefore provides means, as one or more jaws upon the handle, to grasp the object, a bolt for locking such means upon the object in their grasping position, and a connection as a flexible cord between the bolt and the wrist of the operator, which automatically pulls the bolt and releases the jaws from the object when the handle is discharged from the hand with the object.

The means of grasping the object may be varied and the means for locking the handle upon the object, provided the automatic detachment of the handle from the object is effected by the act of throwing.

Two species of handles illustrating the invention are shown in the annexed drawing, one being shown in Figures 1 to 7 and the other in Figs. 8 to 11. Fig. 1 is an elevation of the hand and a two-jawed handle in the act of releasing the ball; Fig. 2 is a side elevation of the handle with two jaws; Fig. 3 shows the inner side of one slide carrying one of the jaws, with dotted lines representing parts of the other jaw the inner side of which is shown in Fig. 5; Fig. 4 is a plan of the handle; Fig. 5 shows the inside of the slide which is represented in dotted lines in Fig. 3; Fig. 6 is an end view of the handle; Fig. 7 a section on line 77 in Fig. 1; Fig. 8 is a side view of a handle having a plug and a movable jaw to engage a metal socket upon the ball; Fig. 9 is a section on line 99 in Fig. 8;

Fig. 10 shows the bottom end of the plug and the adjacent flange; Fig. 11 shows the inner side of the socket with the plug and the jaw engaging the socket.

a and a are jaws connected respectively to slides b and b, the slides being shown with flat adjacent surfaces and straight ball-races thereon.

A rib 0 is formed lengthwise of the slide 6 and has ball-grooves 0 in its opposite sides, as shown in Figs. 6 and 7 and the slide 5 is formed with a channel cZ having ball-grooves d in its opposite sides and so proportioned that balls 6 just fit between the grooves 0 and d.

Nothing exists to hold the slides b and b movably together, as will be obvious from inspection of Fig. 6, until the balls are inserted in the grooves, and the engagement of the balls with the grooves (Z then holds the parts movably together but prevents their disengagement.

Pins 7, f are screwed through the outer walls of the slide 5 into the ball-channels as shown in Fig. 4:, and springs c are inserted in the channels between the pins f and the partitions to press the balls normally toward the pins '7. WVhen the jaws a, a are separated, the balls tend to roll toward the pins 1" and to compress the springs, and to roll in the opposite direction toward the pins 7 when the jaws are retracted.

The springs operate to keep the balls in the most favorable position for separating the jaws to their fullest extent. The balls thus permit the jaws to be moved toward one another, when entered in the holes 9 in a bowling ball it, so as to grip the ball when the slides are locked together. This is effected by a rack h located in a recess 2' in one of the slides, and a spring-l'mlt ;,5 formed as a sloping ratchet-tooth attached to a plate 70 which is movable transversely in the slide 6 and provided with a spring m to press the bolt normally toward the rack. The jaws are thus automatically locked when they are pressed together and entirely released so as to separate freely when the bolt is Withdrawn. This is effected as shown in Fig. 1, by a cord Z attached to the bolt and looped around the wrist n of the operator.

The length of the cord is so proportioned that the operator may freely grasp the handle, fit it into the holes of the ball and push the jaws together to lock them auto mat-ically upon the ball, and also permit the handle a few inches of movement with the ball when the ball is discharged, which movement tightens the cord Z, retracts the bolt and frees the handle from the ball. The handle then remains attached to the Wrist of the operator in readiness to engage with another ball.

The engagement of the jaws with the holes of the ball and the locking of the jaws therein can be effected in a moment, and the operator in discharging the ball is not required to perform any act except to throw the handle with the ball, thus avoiding any manipulation of a latch or bolt at the moment of his taking aim with the ball, and enabling the operator to concentrate his mind entirely upon such aim.

The essential feature of the invention is the automatic detachment of the handle from the ball when the handle and ball are discharged by the operator, and another form of the invention is therefore illustrated in Figs. 8 to 11, where the handle is a cross-head 0 having a hollow shank p with a plug 9 at its lower end and a hook or jaw r movable from one side of the plug to engage a lip .9 within a sockett in the ball. Such socket is shown in Fig. 9 as a screwplug and the jaw or hook r is formed upon a lever a pivoted movably in the shank and actuated by a locking-bolt a), to. which a cord to may be attached for connection to the op erators wrist; The lever u is formed near its opposite ends with inclines a projected toward the bolt, and the bolt has opposite inclines c which operate, in opposite movements of the bolt, to lock the hook r in its operative position or to positively disengage the same from the lip s. A flange 0: is shown upon the base of the plug 9 to arrest the plug when inserted in the socket sufficiently for the hook 1" to engage the lip, and ears w are projected from the side of the shank upon which the hook 9" is located, to hold the plug from rocking in the socket and thus straining the hook unnecessarily. In this device the plug is inserted in the socket and the bolt pushed downwardly, thus locking the hook in the socket as shown in Fig. 9, and the discharge of the handle and ball jerks the bolt outwardly, thus bringing the outer incline against the outer end of the lever to and instantly retracting the hook from the lip. Both constructions thus operate the same, and they adapt the invention for application to objects of different characters where the two jaws or the straight shank may be preferable; but the two jaws are the most suitable for manipulating bowling balls because the middle portion of the handle is wholly unobstructed for applying the hand.

It will be understood from the above description that the bolt is not withdrawn until the handle has left the hand of the operator, and the bolt and jaw therefore have no load upon them and are retracted with a minimum of resistance.

A construction in which the handle is discharged by the operator with the ball thus possesses great advantages over any in which the handle is retained in the hand and the ball is discharged from the handle by moving the bolt, while the aw is sustaining the weight of the ball, as such weight necessarily causes a greater resistance to the retraction of the jaw and of the bolt which locks it. My construction differs from others in having a movable locking mechanism which engages the ball with the handle independent of any muscular effort on the part of the bowler. In my construction no effort is required on the part of the bowler to maintain the handle in engagement with the ball while throwing the same, as the engagement is efiected mechanically, and the movable mechanism upon the handle, which engages the ball, is connected with the hand independently of the handle, as by the cord Z, so that the locking mechanism automatically releases the handle when the handle and ball are discharged by the operator.

Having thus set forth the nature of the invention what is claimed herein is:

1. In a bowling ball handle, the combination, with the handle, of movable mechanism upon the handle for locking the handle to the ball, and a cord connecting such movable mechanism with the hand of the bowler, independently of the handle, for automatically unlocking the handle from the ball when the handle is discharged with the ball.

2. In a bowling ball handle, the combination, with means for grasping the ball, of a bolt for locking the handle upon the ball and means connecting the bolt to the hand of the operator for automatically releasing the handle from the ball when discharged.

3. In a bowling ball handle, the combination, with means for grasping the ball, of a bolt for locking the handle upon the ball, and a cord attached to the bolt and secured upon the hand of the bowler to automatically draw the bolt when the ball is discharged.

4. In a bowling ball handle, the combination, with inclined jaws to fit inclined holes in the ball, of slides connecting the jaws movably, a bolt for locking the slides together, and means connected with the bolt for automatically retracting the bolt when the handle and ball are discharged.

5. In a bowling ball handle, the combination, with two inclined jaws, of slides connecting the jaws movably, ball-races upon the slides, balls guiding the slides movably, a ratchet-bolt and a rack upon the slides respectively to look the jaws together, and a cord attached to the bolt for connecting it to the hand of the operator.

6. In a bowling ball handle, the combination, with two inclined jaws, of slides oonnecting the jaws movably, a tongue upon one of the slides with ball-races at opposite sides, and the other slide having a channel with ball-races in its edges, balls fitted to the races, a rack upon one of the slides, and a spring-bolt upon the other slide to engage the rack, the whole arranged and operated substantially as set forth.

7. In a bowling ball handle, the combination, with two inclined jaws, of slides connecting the jaws inovably, a tongue upon one of the slides with ball-races at opposite sides and the other slide having a channel my hand in the presence of two subscribing witnesses.
