This invention relatesto agame ball catapult.

Antobjectof the'sinvention 'is to provide 'a game apparatus including a club or ballsprojector.

A further object of. the invention-is to provide game apparatus including a club or ball projector having novel and simplified construction.

Afurtherobject of-the invention is lac-"provide game apparatus of the above'mentionedclass which is durable; easy to operate, and practical and inexpensive to manufacture.

Other objects and advantagesof. the invention will" be apparent duringthe course of 'the' following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side e evation of the club or ball projector, and illustrating the action of the same.

Figure 2 is a plan view of the club or projector.

Figure 3 is an enlarged fragmentary central longitudinal section through the club shank and sliding handle section mounted thereon.

Figure 4 is a transverse vertical section on line 5-5 of Figure 4.

Figure 5 is an enlarged fragmentary section through the movable head or hammer of the club.

In the drawings, where for the purpose of illustration. is shown a preferred embodiment of our invention, the numeral !5 designates a club or ball projector as a whole, and this club is preferab y formed of a single sect on of suitable standard metal tubing of a light gage, and bent or formed into the desired shape. The club l5 comprises a projects upwardly from the ground and is inclined rearwardly when the club is in use, Figure 1. The top end of shank it carries a relatively stationary handle section IV, as shown.

At its lower end It, shank is is bent downwardly and laterally out ardly to form a substant ally vertical depending leg !9, bent at i s bottom end to form a circularly curved side 20 of a horizontal circular ring or ground-engaging foot 2!. The ring 2! includes an opposite circularly-curved side 22, having a free end 23 spaced slightly laterally from shank l6, as viewed in Figure 3. Side 22 is carried by the bottom end of one straight upwardly-inclined side 24 of a forwardly-projecting upwardly-inclined track straight elongated shank 16, which 311';

andnslig htly. inclinedxdownwardly-itowarda itsfor:- ward end, which is disposed slightly forwardly of ring2 I. Rigidlymounted uponthe top side of strap 28, at its forward end is a propelling block or hammer 29, having a circularly-curved concave forward face 30. Face 30 is longitudinally curved, with respect to strap 28. The block 29 is secured to strap 28 by means of screws 3|, or the like. The block is preferably of the same width as strap 23. Near its forward tip, strap 28 is provided with an eye-screw 32, which is anchored in the block 29, as shown. A flexible element or wire 33 is connected at its lower end to eyescrew 32, as shown, and at its top end to an eyescrew 34, anchored in the lower end of a slidable handle section 35, mounted upon shank it. The handle section 35 is generally cylindrical, and free to slide longitudinally on shank it above end 29'.

In making a shot, the slidable handle section 35 is pulled toward the upper end of club shank l5. flexing the resilient strap 28. The ball 36 is placed at the bottom end of track 25, and careful aim is taken. The handle section 35 is then released and block or hammer 29 will propel ball 36 up the track 25 and through the air toward a target. Skill in the use of the club, and the extent of pull on handle section $5 are acquired by practice. The club is light and easy to manipulate.

It is to be understood that the form of the invention, herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of the invention, or the scope of the subjoined claims.

Having thus described the invention, we claim:

1. A game ball catapult, comprising an elongated straight inclined shank, a substantially horizontal loop secured to the lower end of the shank for engagement with the ground and adapted to receive the ball therein, an upwardly inclined straight track secured to the loop diametrically opposite the shank, the shank and track diverging upwardly, a leaf spring secured to the shank and having its free end extending above the loop when the leaf spring is in the untensioned position, and a flexible element connected with the leaf spring near its free end and adapted to be pulled longitudinally of the shank for bowing the leaf spring so that it engages behind the ball and being releasable so that the leaf spring can propel the ball up the track.

2. A game ball catapult, comprising an elongated straight inclined shank, a substantially horizontal base secured to the lower end of the shank for engaging the ground and adapted to receive the ball, an inclined straight track secured to the base at its side opposite the shank, the shank and track diverging upwardly, a normally substantially straight leaf spring secured to the shank near one end and extending above and across the base when in the normal untensioned position, an element mounted upon the shank and adapted to slide longitudinally thereon, and a flexible element connecting the element and leaf spring and serving to draw the free end of the leaf spring downwardly near the base and behind the ball when the element is pulled toward the top of the handle, the leaf spring propelling the ball up the track when the element is released;

3. A game ball catapult, comprising a unitary continuous rod including an elongated straight inclined shank portion, the rod being bent at the bottom end of the shank portion to form a substantially horizontal arcuate section, the rod being bent at the end of the arcuate section remote from the shank portion to form a straight inclined inverted U-shaped track portion disposed diametrically opposite the shank portion, the shank portion and track portion diverging upwardly, the rod being further bent at the free end of the track portion to form a companion substantially horizontal ar'cuate section disposed laterally opposite the firstnamed arcuate section and forming therewith a ground engaging base, a leaf spring secured to the shank portion and extending generally longitudinally of the shank portion and over the base, a sleeve mounted upon the shank portion for longitudinal sliding movement, and a flexible element connected with the leaf spring near its free end and with the sleeve.
