pnrajnp ermine ra rnnrr DAVID CUTLER, OF BALTIMORE, MARYLAND.

BOWLING-ALLEY.

To all whom it may concern:

Be it known that 1, DAVID CUTLER, a citizen of the United States of America, and resident of Baltimore, Maryland, have invented certain Improvements in Bowling- Alleys, of which the following is a specification.

This invention relates to a ball-deflecting device adapted for application to a bowling alley, whereby a ball which, by accident or bad play, takes such an oblique course as to pass from the bed to one of the adiacent gutters leading to the pit in which is stationed the setter-up attendant, is returned to the bed at such an angle as will carry it into the pin space, thus giving the player a second chance to score, as will hereinafter fully appear.

In the further description of the invention, which follows, reference is made to the accompanying drawing, forming a part hereof, and in which Figure 1 is a plan view of a part of an ordinary bowling alley, provided with the present invention, and 2 an end view of Fig. 1, looking in the direction indicated by the arrow in that figure. Fig. 3 is a section taken on the broken line ac-m in Fig. 1, except that the device forming the subject of the present invention is shown in full lines. Figs. 4, 5, 6. 7 and 8 are sections of Fig. 3 taken respectively on the broken lines a, 72, 0, cl and 6.

Referring now to the drawing, 1 is the bed of the alley, and 2 the pit at the end thereof.

3. 3 are the gutters at the sides of the bed, and 4. 1 the guard rails of the gutters.

5, 5 are the ball-deflectors which are placed in the gutters 3 and secured therein by any suitable means. The securing devices shown in Figs. 1, 4, 7 and 8 of the drawing. consist of angular metallic strips 7 fastened by screws to the upper surface of the deflectors and the inward surface of the guard rails.

The deflectors consist each, in a block the under surface of which has a transverse curvature corresponding to that of the gutter as shown in Figs. 5, 6, 7, and 8. The inner side of the block is provided with a longitudinally ascending groove, or open Specification of Letters Patent.

Application filed April 17, 1914. Serial No. 832,431.

channel 9 the bottom of which at the entrance end, is flush with the curved surface of the gutter, so as to offer no obstruction to the entering ball; and at the delivery end is flush with the upper surface of the bed 1. The channel 9 is also curved inward toward the longitudinal central line of the alley, as best shown by the dotted line 2 in Fig. 1.

In order that the ball in traversing the upwardly inclined surface of the channel, will not by inertia rise higher than the bed 1, as it is delivered thereto, the channel, while it may be open at the top at the en trance end, becomes gradually covered as it approaches the discharge or delivery end, as best shown in Fig. 2 in which balls denoted by 12 are seen as having passed to the bed.

From the foregoing description. it will be understood that the ball upon entering the channel has its course gradually changed to one leading to the bed, and at the same time. is prevented from rising to any appreciable extent above the bed. thus adapting it to strike pins in its path in a manner similar to that of a ball delivered straight along the bed.

I have shown and described what appears to me to be the most advantageous construction of the ball-deflector, but it is evident that many alterations in the same can be made without changing the result of its employment which consists in conducting a ball which has left the bed and passed to the gutter, again to the bed in such manner that it is possible for it to strike one or more of the standing pins.

I claim as my invention 1. In combination with the bed of a bowling allev having a gutter at the side thereof, a ball-deflect ng device situated in the gutter, p ovided with a curved longitudinally extending channel which connects the said gutter with the surface of the bed.

2. Tn combination with the bed of a bowling alley having a gutter at the s de thereof, a ball-deflect ng device situated in the gutter. provided with an upwardly inclined and inwardly curved channel whereby a ball traversing the channel is transferred from the gutter to the surface of the bed.

3. In combination with the bed of a bowling alley having a gutter at the side thereof, the bed in a direction leading practically to a ball-deflecting device situated in the gutthe spots for the standing pins.

ter, the same having an upwardly inclined, T

and inwardly curved surface Which leads ID CUTLER from the bottom of the gutter to the surface Witnesses:

of the bed, whereby a ball traversing the R. EDGAR QUARLEs,

said surface is transferred to the surface of E. S. QUAnLns.
