Operation When the table I 0 is to be used for bowling, the gun base 33 will, of course, rest rmly upon the table I3, and the T-shaped guide rail 34 will be engaged under the edges of the strip 3l so that the gun 32 will have a stable means of support, while the player may move the gun laterally to any desired position, and also swing the gun upon the vertical shaft 36 so as to aim the gun accurately. l

The player may insert the ball 50 in the semicylindrical barrel portion 49, pull back the plunger 44 by means of the handle 46, aim the gun 32, and then release the handle 46 so that the spring 41 will drive the head 45 forwardly to strike the ball 50 and project it from the barrel 40.

While there has been disclosed in this speciiication one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosure, but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes all modifications and embodiments coming within the scope of the following claim. Y

Having thus fully described the invention, what is claimed as new, and for which it is desired to secure Letters Patent, is:

In a bowling ball projector for a game board, a base, a barrel mounted for horizontal swinging movement on said base, said barrel being upwardly tilted at its forward end to prevent the ball from leaving the barrel prematurely, a headed plunger at the rear of said barrel for propelling a ball through said barrel, a U-shaped guide block supported by said base for slidably holding said plunger, a coiled spring surrounding said plunger and engaging the guide block .and the plunger head, said barrel being cut away at thetop of its rear section to permit the ball to be `dropped therein into propelling position in front of said plunger, said plunger having a verticalfslot in its forward end, an upward projection in the rear portion of said barrel located in said slot to prevent the ball from following .said plunger rearwardly when it is retracted against its spring to loading position, a handle on the rear of said plunger, and a spring cushion located between said rear handle and said U- shaped guide block to reduce the noise of impact and to prevent injury to said handle.
