In the embodimentof the invention illustrated in-the drawings, there is provided an alley @arranged with an alley or bowling, board, lz adapted for the setting thereon of a series of pins P in predetermined spaced relation at the rear,end. A ball runway 13 is arranged longitudinally of the alley to return the bowling balls B frointhe rear end to the forward end thereof, said runway having a portiondeclined from the rear end toward the front end of the alley and merging into an upwardly inclining portion -and the alley merging with a ball support at the forward extremity, whereby the balls will roll by gravity from the 'rearend to the forward end of the runway. To automaticallydeliver balls to said runway and return the balls to the forward or players end, there is provided aball receiving pit M at the rear end of the bowling board, the rear of which pit is extended upward and provided on the surface with a cushioning means IS.

The rear end of the ball runway 13 opens to a side of the pit with the outer wall thereof extended to constitute a .side wallof the pit. The

bottom l6 of thepit is arranged to incline from the rear ofthe front end and from the side opposite the ballrunway toward the entrance to said runway,- whereby the balls will roll from the" pit into the runway.

. In the embodiment of the means to set and spot the pins relative to the bowling board and clear. pinswhich have been knocked over from the bowling board by a ball rolled from the front end of the alley, whereby aplayer may also set and clearthe bowling board of pins andv thus eliminate the services of the usual pin boy to set the pins. For this purpose, the bowling board is providedwith a series of openings ll arranged in predetermined spaced relation,- in the present instance arranged to. conform to the setting of pins in the ten pin bowling game Pinreceiving housings are extended below the bowling board and open. to said openings and supported from the bottomof the bowlingboard by brackets l9, asshown in Figures 3- and 9. k

To support the bowling pins within and in set position relative to the bowling board, a support in. the form of a block 20 is arranged in each housing to have sliding movement outward from and into, the housing, theblock beingguided by secured in the lower end of the tube, the convoa pin 2| fixed therein and'extended laterally through a slot 22 in the wall of the tube, and saidpin limiting the outward movement of the support by engaging the under-surface of the bowling board. In normal position, the supports 29 with the bowling pins within the housings, the support engages and is supported upon a piston or ram 23 in each housing, as shown in Figure 5, and the piston is actuated to move the pin support 20 upward and to eject the bowling pin from the housings onto the bowling board by a spiral spring 24,'the one end of the spring abutting and being supported by a closure 25 lutions of the spring coils at the upper end being of reduced diameter and seated in a recess in, the bottom of the piston 23, as shown at 26, The piston 23 is normally releasably held in posi tion 'withthe spring compressed and the bowling pin and support therefor within the housings, as

shown in Figure 5, by-a latch '21 in 'theiform of a lever p'ivotally supported intermediate the ends by a bracket28 fixed 'to the exterior of the housing, the endsof the latch being extended in opposite directions'at sub'stantiallya right angle. The one endof the latch is arranged with a nose 29 by rounding the corner at the endandupper surface of the latch, and the nose is arranged in opposed relation to and m movement into, the housing through an opening 30 to engage afiat face of the nose with the end of the piston, the latch being urged by a spring 3| to extend the r noselinto the opening 30'for engagement by the piston and suchmovement beingpredetermined and limited by a pin 32 extendedtransversely throughthe latch an'd the opposite'ends adapted to straddle and engage the tube at the opposite side walls of the opening,

To; eject the pins from the housings ontothe bowling board'and position the supports 20 with the uppersurface;substantially fiush with or in a plane slightly below the upper surface of the bowling board, as shown in Figure 6, the latches 2? areactuated to move the'nose 29 out'of'engagemerit and release the pistons 23, as; shown in Figure 6, whereby'the pistons with the superv posed pin supports andfbowlin'g pins arem'oved upward,the supports being retained in position at the upper end-of the-housings by; the flat underside of anose 32'of a'latch 34, similar to latch 21, engaging below and'with-an' end surfaceof an annular recess in the supports formed 7 by reducing the diameter. of theendof the supports. The latches 34are pivotally supported intermediate the ends by brackets 35 fixed on the exterior of the housing, and; are urged by springs 36-to extend the nose-through ans-opening 3! into the housings, such movement being limited by the ends ;of a' pin'38 extended trans versely' through the latch straddling the opening 31. The end of the nosefopposite to'the 'fiatface is rounded, and the end of the supports is also rounded, whereby as the supportsmove pass the i nose extended into the path of movement thereof the rounded edge of the supports will engage the rounded portion of the nose thereby'not only readily passingthe nose, but actuating the latch on its pivot supportand move the nose out of the path of movement of the support, andas the upport movesbeyond the latch nose the latch. will be instantly actuated by its spring 36 to engage the nose below the shoulder formed by, the reduced end of the support. In this condition, the parts will be in the positions shown'in Figure 6, and to set and spot the bowlingpins P upon the supports 20, as shown in Figure 7, and restore the springs 24 to their compressed condition with the'pistons 23 relative to the nose 25 of latches 21 to hold the springs in compressed condition, as shown in Figure 5, there is provided a rectangular plate 39 supported in a horizontal positionbelow the housings l8 to have movement in vertical direction toward and away from the lower end of the housings, and supported and urged toward the housings by springs:40, there being four of said springs in the present'instance, one adjacent each corner and attached at one M end to an eye of bolts secured in the plate, as at, 4I,jand the opposite end of the brackets attached to members 42 secured in and extending from the, bottom of the bowling board. To guide the actuating plate 39 in its movements, vertically fixed posts 43 are provided to extend between they bowling board and the supporting floor 44 r for the slidable engagement of recesses in, the corners of the plate,;as shown in'Figures 2, 3, and 4; The plate is'actuated against the tension of the supporting springs by a series of four cables or chains 45 fixed at one end to drums 4 6 fixed to the opposite ends of a shaft 41 rotatable in abracket 48, the opposite ends of the cables,

being secured-to the spring connecting bolts 4| for the supports 40, The shaft is urged by a spring 49 to unwindthe cables from the drums, .36

and is rotated to wind the cables on the drums and move the plate 39 against the tension of supporting springs by a pivoted lever 50 (Figure l)having ahand grip at one end and the opposite end connected to an arm 5 lgfixed on a shaft-52 rotatable'in bracket by a cable or chain '53 engaged around a grooved pulley 54 and attached at one end to the lever 50 at the endopposite the hand'grip and at the opposite end to the arm 5|, a' toothed wheel or segment 55fixed ontheshaft 521meshing with a, pinionv 56 fixed on the drum shaft 41. To exert a pulling-force on the platethrough the. cables 45 and toguide said cables to the drums 46, they are engaged about grooved pulleys 51, rotatably mounted in brackets fixed to the floor 44.. l By the movement of the lever 50 in the direction indicated by the arrow in Figure hthe drumshaft 52 will be rotated'against the tension of spring 49 and move plate 39 against the tension of its supporting springs 40.

which may be a cable or chain, is fixed at one end to each of ,th'ebowling pins within a recess in the bottom thereof and is extended through openings in" the pin supports, and pistons 23,v

through the "spring'24, an opening, in the end closure'disks 25 of the housing; and openings in the plate39, which may be the same openings" through which the piston actuating members 58 extend. Each of said flexible members, has

I an abutment 63 securedthereto at some distance from theabutments 60 on the members 53, and

said abutments 63 being carried at the end of auxiliary flexible members '62 attached atthe end opposite the abutments' to thefiexible members SI for a purpose to be hereinafter described.

In the exhausted position of the piston actuating springs 24 the pistons 23 and pin supports are in the positions shown in Figure 6, and the pins in knockedover position on the bowling board with the abutments 60 engaging the plate 3! and the abutments 63 some distance below said plate. In this position of the parts, the hand lever 5 6 is actuated to rotate the drums 46 to wind the cables 45 thereon and thereby moving the plate 39downward, the plate engaging abutments 6D drawing the pistons through the members 58 downward, the pin supports 28 being retained in their elevated positions due to the engagement of the latches 34 therewith. As the pistons ride over the rounded nose 29-01." the latches 27, they will actuate said latches to move the nose of the latches out of the path of movement of the pistons, and when the pistons pass the latch nose they will be projected into the housing by the springs 3! to engage over a marginal portion of the pistons. In this position of the pistons, the actuating plate 39 will bein the dot and dash line position shown in Figure 6 engaging the abutments 63 and the continued downward movement of the plate and adjustment of the pistons to the position shown in Figure 7 i will take up the slack in the flexible members 59 and thereby move the bowling pins to set and spot them on the supports 20 held by the latches 34, as shown in Figure 7. The hand lever is then relieved of the actuating force when the drum returning spring 49 and the plate supporting springs will return the actuating plate to the position shown in Figures 5 and 8 and in dot and dash lines in Figure 7, with the pins P set upon the respective pin supports 26, as shown in Figure 7, and the springs held in compressed condition by the nose of the latches 21. engaging the pistons, as shown in Figuresfi and 8;

To clear the bowling board of pins which have been knocked over, the flexiblepin setting members 65 are each engaged about grooved pulleys rotatably carried by brackets 66 fixed to the floor 44 and the opposite end connected with the latches 34, the flexible members 6| being of a length to provide a slight. slack therein with the pins in said position, as shown in Figure '7, to permit a pin P as it is struck by a ball to be partially knocked over and take up such slack and during the initial falling movement of the pin to the bowling board, exert a force on the latch to move the latch nose out of engagement with the pin support 20. As the nose 33 of the latches 34 is moved out of engagement with the pin supports 20, said supports will drop by,

gravity in the housing [8, as shown in dot and dashline in Figures, into engagement with and to be supported by the pistons 23. To connect the bowling pins P with their supports 20 and permit the pins to have a limited movement relative to their supports, for instance, to permit said pins to be ejected from the housings onto the bowling board, as shown in Figure 6, an abutment 64 is fixed on each of the flexible members 61 and arranged in pockets formed byopposed recesses in the pistons and pin supports 20 with the parts as shown in Figure 6. The pin supporting blocks 2b are of a weight slightly greater than the weight of the pins, and as said supporting blocks drop in the housings, by the release of the latches therefrom as the pins are knocked over, the supporting blocks will engage'with the abutments 64, thereby coupling the blocks through the flexible members 61' withthe bowlas shown in do: and'dash line in Figure 8 and in full linesin Figures 3 and '5.

To set the bowling pins, the latches 21 are re leased from the pistons 23 to permit the pistons to be actuated under the influence of the springs 24 The latches 21 are released from the pistons by and during the initial downward movement of the actuating plate 38. For this purpose, an elongated U-shaped member 61 is movablyconnected at the leg connecting portion to each of the latches 21 to be suspended therefrom with the ends of the legs free, as shown in detail in Figure 1D. The legs of these members have a constricted portion, as at 69, at a predetermined point between the ends to arrange said ,members with an abutment, and said members are extended through openings 68 in the actuating plate 38' having a cross sectional area substanti-ally the same or slightly greater than the constricted portion '59 of the legs of said members. Topermit of a slight rocking movement of the members 6! relative to the latches, as for instance from the dot and dash line to the full line position in Figure'6, bolts having rounded heads are secured in the latches 21, as shown at H7 in Figure 10, and the members 61 are secured to said bolt heads by filister screws H extended through an opening in the leg connecting portion of the members, 6'! and threaded into the bolt heads. In the normal position of the parts with the bowling pins within the housings, as shown in Figure 6, the constricted portion 89 of the members 61 engages the openings 68 in plate 39, and as the plate .is moved downward, the constricted portion 69 will form' the relief of the force of the plate on the abut merits 68 being returned by the springs 31 to their normal position shown in Figures-5 and 7; During the return movement of the plate 39,

the walls of opening 68 will again be positioned relative to the. constricted portion 69 of the membersflj It will be obvious that various modifications may be made in the construction and arrange ment of parts, and that portions of the invention may be used without others without departing from the scope of the-invention.
