SPECIFICATION forming part of Letters Patent No. 537,927, dated April 23, 1895.

Application filed September 24,1894. Serial No. 524,007- (No model.)

To all whom it may concern:

Be it known that I, ALBERT H. KENNEDY, a citizen of the United States, residing at Rockport, in the county of Spencer and State of Indiana, have invented a new and useful Ball-Bat, of which the following is a specifica tion.

My invention relates to ball bats in which the bat is divided into two parts somewhere near the middle and a spring is interposed between them. This spring is introduced to give elasticity to. the bat to such a degree as is not possible to secure in any other manner.

The object is to save the strikers hands from the jar that is usually received with the ordinary bat, and to impart a greater degree of force to the ball and thussend it to a greater distance; also to combine different kinds of wood and thus balance the bat to suit ones fancy. I attain these objects by the mechanism illustrated in the accompanying drawings, in which-- Figure lis a View of the bat as a whole, and Fig. 2 a view of the screw links that connect the whole together. Fig. 3 is a detail showing the spring washer or cushion. Fig. 4 is a sectional elevation of my improved ball bat.

A and B, Fig. 1, are two separate pieces of wood or other suitable material. They are enlarged a little at D, D, Fig. 1, by turning the wood a little larger or adding metallic ferrules to strengthen the parts.

0, Fig. 1, is a rubber cushion of sucha consistency and thickness to give the desired elasticity.

' E, E, Fig. 2, is the screw link that holds the two partsA, B, Fig. 1, together.

The ends D, D, Fig. 1, are bored out and tapped to receive the screws E, E, Fig. 2.

C, Fig. 3, shows the rubber washer or cushion.

Other devices might be used, such as a coiled spring into which the two ends D, D, might be screwed, to accomplish the same end.

I am aware that prior to my invention bats have been made but none to niy knowledge have ever been made in two parts with an interposed spring to secure a large degree of elasticity.

\Vhat I claim as my invention, and wish to secure by Letters Patent, is-

1. A ball bat comprising separate parts of relatively rigid material connected by an elastic or yielding joint.

2. Thecombination in a ball hat of the two parts A. 13., a flexible, mechanical connection joining said parts and the interposed spring or cushion 0., substantially as and for the purpose set forth.

3. The combination in a ball bat of the two parts A. 15., the screw-hinge E. E., and the
