- My invention relates to games and particularly to a toy bowling game. More specifically, it relates to an apparatus for hurling or throwing a toy bowling ball or the like. 7

One of the objects of the invention is to provide a device of this character for hurling a toy bowling ball, and which is provided with means for imparting a spinning movement to the ballin either of two directions, at the option of the operator, whereby the ball will travel" in a path which curves either to the left or to the right 7 Another object is to provide a device of this character in which the rate of the spinning movement imparted to the ball may be varied, whereby the degree of curvature of the path thereof may be varied. Another object is to provide such a device in which the velocity at which the ball is hurled may be varied at the option of the operator. A further object is to provide a device in which the directionin which the ball is hurled may be varied and the speed at which it is hurled may also be varied by using either the right or the left hand of the operator.

I accomplish these objects by means of the novel elements and thecombinations and arrangements thereof described below and illustrated-in the accompanying drawings in which-- 2 end a ball gripping means represented generally by the numeral I! which is secured to a hollow I shaft l8 by means of a set screw 19' (see Fig. 1).

Fig. l is an elevation view of'my device with certain portions broken away and showing it clamped to a table or board forming the alley along which the ball is thrown; and

Fig.2 isa right hand view of the device, as

a shown in Fig. 1, with the movable ball-hurling element in substantially a vertical position.

Referring to the drawing I My device comprises a base plate I which is pivotally connected at 2 to an underlying plate 3 which is adapted to be secured to a'table top 4, 'or the like, by clamps, such as shown at 5 and 6.

The base plate I carries two 'spacedupright members, 1 and 8, each of which is provided on the outer side thereof near the bottom, with a hand grip 9 by means of which the base plate I and the uprights] and 8 may be swung about the pivotal connection 2 with either the right or the left hand of the operator. Mounted in sleeve bearings 10 and ll which'are secured in the uprights 1 and 8, respectively, by means of screws 12 and I3, is a horizontal shaft 14 which is freely rotatable in said bearings. Secured to the shaft M by means of the set screw 15 (see Fig. 2) is a pendulous element represented generally by the numeral Hi. This element carries at its lower The shaft l8 extends axially of the pendulous element and is rotatably mounted in the bearings 20 and 2| (see Fig. l).

The ball gripping element ll comprises a hollow, spherical dome or shell 22 having three arcuate ball gripping members 23 pivotally mounted therein, as shownat' 24 in Fig. 1. These elements are adapted to grip the ball in a zone extending slightly below the equatorial zone thereof and are'yieldinglyheld in contact with the ball by means of the connecting helical tension springs 25. The gripping members 23 have extensions 26 disposed on the opposite sides of their pivotal connections 24 which are in contact with a circular disc 27. The disc 21 isconnected to a push rod 28 extending through thehollow shaft l8 and which, at its upper end, is adapted to cooperate with the cam 28 secured to the sleeve bearing ID by means of the set screw 30. The tension of the springs 25 normally maintains the upper end of the rod 28 in contact with the surface of the cam 29. The cam 29 is provided with at least one high point or zone 3! and, when the end of the rod 28 rides up and upon thiszone, the disc 21 depresses the extensions 25' of the ball-gripping means and effects an opening movement 0f said means against the tension of the springs 25 to release the ball. The position of the high point 3! of the cam may be adjusted by loosening the set screw 38, turning the cam on the sleeve Ill and tightening the set screw to hold it in adjusted position.

In order to impart a spinning motion to the ball 32 so that itwill traverse a curved path after it is delivered from the hurling mechanism, I have provided a means for rotating the hollow shaft IS in its bearings. This means comprises a friction wheel 33 which is slidable longitudinally on the shaft I8 by means of the knob 3 having the forked lever 35 thereon which rides in a collar 36 on the wheel 33. A flat spring 37 frictionally engages the frame members 38 and 39 to hold the wheel 33 in any position to which it is moved. It is understood, of course, that the friction wheel 33 is drivingly connected to the shaft 13 by means of a spline or otherwise.

Fixed to the ends of the shaft M by means of set screws 4!) (see Fig. 2) are knurled knobs 4i and 42 having pulleys 43 and M, respectively, secured thereto. Connected to the pulleys 43 and 44 by means of pins 45 and 45 which are vertically disposed below the axis of the shaft I l when the pendulous carrier [6 is vertical, are tension springs 41 and 48, the other ends of which are shown as fixed to the handles 9 by means of the hooks 49 and 50. These springs normally but yieldingly hold the pendulous carrier 16 substantially vertical. The two knobs 4| and 42 are provided so that they may be manipulated conveniently by' either the rightor the left hand of the operator to turn, the shaft 14 and swing the pendulous carrier I6 back into a position such, for example, as that shown in Fig. 1; If the knob by which the carrier is swung into the position shown in Fig. 1 is released after the springs 41 and 48 have been stretched to the desired degree, they will impart a rapid forward swinging movement of the, carrier which will carry it past the dead center, and'the springs will then function as a brake to bring the carrier back to its normal vertical position after a few shown in Fig. 2, thepath of the. ball will. be

straight. However if it is desired to have the ball traverse aflcurved path, .a spinning movement may be imparted'thereto by moving either the arcuate plate 5! or the arcuate plate 52 into running contactwith the frictional wheel 33 and clampingit insuch a position, By reference to Fig. 2, it will .be notedthat thev arcuate plates or discs 5| and 52 are fixed to a base 53 which rides on top of the. uprights 1- and 8,. This, base 5.3.may beslid either to theright to, brin plate 5| in con- ,;leased; a wheel fixed to said shaft; manually movable means at one side of said shaft and normally spaced'from said wheel presenting a surface on which said wheel may roll when in contact therewith, and adapted, at the option of the operator, to be moved into frictional contact with said wheel for automatically imparting a spintact with, the friction wheel, orto the left to bring tohold the. plate inadiusteducontact with the Wheel. .33.

V Referring to liis., 1,.,it, Willbe pparent that, when the friction wheel 33 is p sitio e n ar the outer peripheral edge ofthe disc 52 and is in contact with said disc, it will roll; thereon through a comp rativ y 1.01 s Pathwhen the pendulous element swinesand thereby imparta rapid spinningmovement to the hallg ppine s a the ball therein. If itis desired to' impart a s wer spinning movementto the ball, the fri tion. wheelie mayheislid upwardly and to the lef asviewed in Fi -.11, by means of. he kn b 3.4, so, thatit vwillloenearer theaxis ofthe shaft is about whichitrevolves. Thu whenthe pen ulous element swings the wheel 33 will roll through a shorter are. and impart a slower spinn e movementto the ball. than when the po tion shownin Fig, 1.
