5 Claims.

This invention relates to bowling alleys which may be readily transported and adapted for use in the homes or at pleasure resorts, and it is the principal object of the invention to provide a bowling alley which may be played from either end, so that the opponentsof a bowling match maybowl from opposite ends of the alley and set up the pins of their opponent and return their opponents balls.

It is another object of the invention to provide a novel pit sectionpivotally mounted on a side of a bowling board and adapted to be releasably secured in mating relation with the ends of the bowling board to receive balls thrown from the opposite ends and to be positioned to extend at, a right angle to the ends of the bowling board to permit a bowler to throw or deliver a ball from one end toward a set of pins set up at the opposite end of the bowling board without interference, and said pit sections being constructed to receive the thrown balls and knocked over pins and prevent said balls and pins rebounding from said pit sections to the bowling board.

It is a further object of the invention to adapt a bowling board for the removable mounting of a transverse bar arranged with a resilient facing, whereby a ball is thrown from the end of the bowling board where the pins are set up toward the transverse bar and is repelled by the resilient facing toward said pins.

' t is a still further object of the invention to provide a novel construction of ball return gutters in the longitudinal side edges of a bowling board and ball retaining walls along said edges.

Further objects and advantages of the invention will be set forth in the detail description of the invention. 7

Like characters will designate like parts of the invention throughout the drawings and the fol-, lowing detail description of the invention.

In carrying out the embodiment of the invention illustrated in the accompanying drawings, there is provided a bowling board 9, which may beformed of a single plank or a series of juxtaposed boards, having a smooth upper surface arranged at the opposite longitudinaledges with cut out portions of right angle shape in cross section, as shown in Figure 4, having an intermediate section, constituting the greater part of their length, of uniform depth, as shown at H), and the opposite end sections of the cut out portions of progressively increased depth to have the horizontal surfaces thereof declining from the intermediate sections to the opposite ends of the bowling board, as shown at H. The cut out portions Ill, H are adapted to form gutters for the return of balls B to either end of .the bowling board by walls or rails having an intermediate portion IZ of uniform width' greater than the thickness of the bowling board 9 and of a length substantially the same as thelength of the cut out portion Ill, and opposite endportions l3 of progressively increased width to form diverging upper edges l4 and of a length slightly less than the length of the end out out portions H. The rails l2, l3 are secured tov the side edges of the bowling board 9 with the lower edges of the rails flushed with under surface of the bowling board and the upper edges of the rails extending above the longitudinal middle portion of the upper surface of the bowling board, and the intermediate rail portions l2 in opposed relation to the intermediate cut out portions l and the end rail portions I3 in opposed relation to the cut out end portions II with the wide end of the rail portion I3 terminating within the ends of the bowling board for a purpose to be hereinafter described. To facilitate the rolling of the balls along the gutters, the corners at the bottom of the gutters are bevelled by strips of suitable material, such as molding, of triangular shape in cross section, as shown at I5 in Figures 4 and 7, secured in said corners. The upper surface of the opposite end portions of the bowling board 9 between the rail portions I3 is arranged with pin spots in the usual groups of ten, as shown at IE, to facilitate the setting of pins P.

The bowling board 9 is supported in elevated position from a floor by standards at the opposite ends and midway of said ends. supporting the opposite ends of the bowling board comprise a pair of uprights I1 connected to and braced from each other by a pair of parallel cross bars I8, I9, the bar I8 being adapted to engage the lower face of the bowling board and support said board, and the uprights being spaced from each other to engage and be connected to the outer face of the rail portions I3. Theconnections between the uprights and cross bars are reinforced by a one piece brace or frame member having upright portions 29 fixed to the standard uprights I1 and cross portions 2! fixed to the cross bars I 8 and I9, as shown in Figure 4. The standard supporting the midway portion of the bowling board 9 comprises a .pair of uprights 22 connected to and braced from each other by cross bars 23, as shown in Figures 1 and 2,

The balls B may be thrown or delivered from either end of the bowling board toward the pins P set .on the spots I6 at the opposite end of the bowln board, and the thrown balls and the pins, which are knocked over by said balls, are received by a pit section pivotally mounted on each end of the bowling board. The pit sections are of box form composed of a bottom 24 having opposite side walls 25 fixed to and extending perpendicularly from the bottom with the upper edges incliningfrom straight side edges 29 to extend as continuations of the diverging edges I4 of the rail portions I3, as shown at 21, and the other side edges of the side walls 25 are arranged with vertical portions adjacent the bottom 24 and inwardly inclining upper portions to accommodate a rear wall having a vertical section 28 and an inwardly inclining section 29, as shown in Figure 6. The rear wall section 29 extends above the upper edges 2] of the side walls 25 and the upper end edge of said wall section 29 extends in are, as shown at 30 in Figures 1 and 8. To prevent the balls and pins entering the pit sections from rebounding to the bowling board 9, there is provided a swinging cushion in each of said pit sections comprising a rectangular frame 31 having one face covered by suitable material, such as a cloth 32, and swingingly suspended from a cross bar 33 fixed to the inner face of the inclining rear wall sections 29 by suitable means, such as hooks and eyes, fixed in the upper cross piece of the frame and the bar, as shown at 34 in Figures 6 and 8. The inclining rear wall sections 29 will also retain the balls and pins in the pit sections. The length of the open side edges 26 of the Side walls 25 is greater than the length of the wide end of the railportions I 3, so that the bottoms 24 of the pin sections will extend below the ,upper surface of the bowling board 9 when The standards the pit sections are mounted on the bowling board with the edges I4 and 21 in alinement with each other, and cause the balls and pins to drop and hit the cushion 3|, 32. The sound of the balls and pins hitting the rail portions I3 of the bowling board 9 and the side walls 25 of the pit sections is deadened and said rail portions and side walls are protected from said balls and pins by a layer of suitable material, such as fabric or rubber attached to the inner surface of said portions, as shown at 44 in Figure 5.

The pit sections are adjustably mounted on the opposite ends of the bowling board to be positioned in juxtaposed or mating relation to said ends to receive balls thrown from the opposite end and the pins knocked down by said balls, and to extendat a right angle to the bowling board to permit the throwing of balls toward the pins set up on the pin spots H5 at the opposite end of the bowling board. The pit sections are mounted on the bowling board by a pair of suitable hinge members, such as ordinary door hinges 33 having one leaf or strap fixed to the outer face of an upright I! of the pair of uprights at each end of the bowling board, one hinge being adjacent to the top of the upright and the other hinge being between the cross bars I8 and 19, as shown in Figure 7. The other leaves of the hinges are fixed to an upright of a pair of uprights 34 constituting a part of a frame having a pair of parallelly extending cross bars 35, 36 fixedat the opposite ends to the uprights 34 with the bar 35 supporting the bottom 24 of the pit sections and the bar 39 at the lower ends of said uprights 34, as shown in Figure 8. The connections between the bar 35 and the uprights 34 are reinforced by a brace having a cross portion 31 fixed to the bar and vertical portions 38 at the opposite ends of the cross portion fixed to the uprights. The uprights 34 are fixed to and extend along the outer face of the side walls 25 of the pit sections adjacent to the open edges 26 thereof, so that in the close position of the pit sections, the uprights 34 of the pit sections will be in opposed relation with the uprights ll of the bowling board 9, and the side walls 25 of the pit sections and the rail portions I2, I3 of the bowling board will extend in the same vertical planes, as shown in Figure 5. The mounting of the hinges 33 in spaced relation to each other will prevent canting of the pit sections and thereby eliminate the use of legs for supporting the pit sections from the floor. The ends of the bowling board 9 will extend over the bottoms 24 due to the mounting of standards I1, i8, I9 within said ends as previously stated, and said overhanging end portions of the bowling board are engaged in the close position of the pit sections by a strip 39 of resilient material, such as rubber, fixed to the upper surface of the bottoms 24 of the pit sections, as shown in Figure 6, said resilient strip absorbing the shock of the pins and ball coming into contact with the bottoms 24 and preventing the transmission of said shock to the bowling board and the hinges. The pit sections are releasably retained in close position by a spring actuated latch comprising a lever pivotally mounted on the upright 34 opposite the upright 34 arranged with the hinges 33, as shown at 49 in Figure 5, and yieldingly urged by a spring coiled around the pivot to position a hook end 4| of the lever into a staple 42 fixed to the upright I'I corresponding to the upright 34 supporting the latch lever and the opposite end of said lever having a finger engaging portion 43 to facilitate the disengagement of the hook end 4| from the staple 42 when it is desired to actuate the pit section to open position.

In the use of the bowling alley, one of the pit sections is actuated to close the adjacent end of the bowling board, as shown in full lines at the right hand side of Figure 1, and a set of pins P is set up on the spots H5 at said end of the bowling board, the setting of the pins may be prior or subsequent to the closing of the end of the bowling board with the pit section, but it is easier to set up the pins while the pit section extends at a right angle to the bowling board, and then the pit section at the opposite end of the bowling board is actuated to extend at a right angle to the bowling board, as shown in full lines at the left hand side of Figure 1, which will permit the delivery of a ball from said end toward the pins at the opposite end of the bowling board without interference.

The bowling alley may also be used by players standing at only one end of the bowling board 9 and delivering balls to hit pins set up at the same end of the bowling board by the use'of a rebound cushion comprising a bar 45 of a length greater than the width of the bowling board and having corners on one longitudinal side thereof cut out, as shown at 455 in Figure 4, to permit the mounting of the bar on opposite sections of the rail portions I2 with said latter longitudinal side of the bar extending in parallelly spaced relation to the upper surface of the bowling board. The face of the bar 45 positioned toward the end of the bowling board at which the pins are set up and the balls are being thrown from, is arranged with a resilient facing member 41 composed of rubber or other suitable material attached to the bar below the longitudinal center thereof and having the exposed face of angular shape in cross section, as shown in Figure 3, so that a. ball striking the said face will rebound along the bowling board toward the pins. The bar 45 is releasably secured to the rail portions l2 by pins 48 engaged in alined openings 49 in the reduced ends of the bar and the rail portions l2. When it is desired to use both ends of the bowling board, the rebound bar 45 may readily be removed from the rail portions I2 by removing the pins 48.
