While this invention is susceptible of embodiment inmany different forms, there is shown in the drawings` and will herein be described in detail an illustrative embodimentof the invention with the understanding that the presen-t disclosure is to be considered as an exemplitication of the principles of the invention and is not intended to limit the invention to the embodiment illustrated. The scope of the invention will be pointed out in Athe appended claims.

As shown in the drawings the pin handling mechanism comprises a turret indicated generally at 1 for collecting and releasing a set of pins, an intermediate deck indicated generally at 2 for receiving and storing pins `re ceived from the turret, and a pin setting deck indicated generally at 3. These parts are sociation with a bowling one side of an alley.

A transversely extending frame member 5 positioned` above the alley is supported at each end by struts angling downwardly to the kickbacks at lthe side of the alley and a pair of these struts at .one side of theA alley' are shown at 6 and 7 in Fig. l.

The turret 1 has a sleeve 10 which is fastened to the 4frame member 5 by collar 11 to support the turret in a fixed position above the alley. Downwardly angled struts 12 and 13 atboth sides of the alley support the ntermei diate deck 2 in a iixed position above the alley andV beneath the turret l. The pinsetting deck 3 is movably mounted for up and down movement between the posi-- tion shown in Fig. 1 and positions therebeneath for picking up of standing pins or setting of pins by a rock shaft 14 mounted between the frame members 6 at opposite sides of the alley. A pair of parallel arms, one of which is shown at 15 in Fig. 1, extend upwardly from the rock shown, in Fig. l, in as-F alley kickback 4 positionedfat Patented June 21, 1960 shaft 14 to pivotally connect as shown at 16 with upstanding frame members 17 and 18 tixed to the sides of the pin setting deck 3.

l`hf':,"turr`et l/comprises means for collecting a set of pins in a predetermined arrangement and forreleasing the set of pins therefrom andas shown particularly in'Figs. 2 and 3 has ten pin receiving pockets 26a through 20j for receiving ten pins forming a set of pins. The turret has an outer part 21 having a ring shape and formed with inwardly facing shoes 22 except for pocket 20a which has an outwardly facing shoe 23. The turret has an inner part 24 disposed Within the outer part 21. The turret inner part 24 has a shoeV 25 for each of the pockets with nine of the inner partshoes 25 lying within the outer part shoes 22. The inner part shoe 25 lies outwardly of the outer part shoe 23 at pocket 20a.

The outer turret part 21 is mounted for rotation centrally thereof to a hollow drive shaft 30 rotatably mounted within the sleeve which is driven by an intermittent drive mechanism secured to the upper end thereof (not shown). The inner turret part 24 isl secured centrally thereof to a shaft 31 slidably mounted within the drive shaft 30. The inner and outer turret parts are caused to rotate together by a pin 32 mounted in a slot 33 in the outer turret part 21 and loosely mounted in a slot 34v in the inner turret part 24. This pin 32 permits relative up and down movement between lthe turret parts and specifically raising and lowering movement of the inner turret part 24 relative to the outer turret part 21.

The turret parts when in their closest position relative to each other support pins between the shoes and the pins are held therein until the inner turret part 24 moves downwardly relative to the outer turret part 21 to increase the distance between the shoes. A plurality of springs 35 are connected at their lower end to the inner turret part 24, as shown in Fig.. 3, and at their upper ends are connected to a sleeve 36 secured to the outer turret part 21. A The springs 35 are sufficiently strong to hold the inner turret part 24'adjacent the outer turret part 21 when one pin is in the turret, but are yieldablewhen a set of pins are in the turret so that the turret parts may move apart relative to each other. In order to prevent movement of the turret parts until a set of pins has been collected, a lock arm 40 `is pivotally mounted on the sleeve 36 by a pin 41 and carries a cam roller 42 engageable with a cam 44 mounted on the sleeve 10. This cam by engaging the roller 42 maintains the lock arm in a counterclockwise pivoted position so as to have an inclined abutment 45 on said lock arm in Aengagement with a roller 46 mounted on the inner turret part 24. The lock arm is urged to this position by a spring 43. When the tur-ret holds a set of pins and is in the position shown in Figs. 2, 3, the roller 42 will be aligned with a drop-out section 47 of the cam 44 and the weight of pins acting on the inner turret part 24 will cause the roller 46 by engaging the inclined abutment 45 to pivot the lock arm 40 in a clockwise direction to thus free the roller 46 and inner turret part 24 for downward movement. The lower end of the lock arm 40 pivotally mounts an arm 50 by a pin 51 which-forms a part of the lock arm and which is forced by a spring 52 into abutting relation with the lock arrn as shown at 53. The free end of this arm 50, as shown in the full line position of Fig. 3, may be selectively engaged by a part hereinafter described to block movement of the lock arm 40 when the turret would otherwise drop a set of pins in the event the intermediate deck 2 is not ready to receive the pins. Turret 1 as shown in the positions of Figs. 2 and 3 is m a position to discharge pins therefrom tothe intermediate deck 2 and is also in a 'position to` receive a first pin of a new set in the pocket 20a. Inasmuch as the lock arm 40 is free for movement in this position, the springs 35 .function to maintain the turret parts together -if only` a single pin is in the turret. The turret iS then indeXd topresent successive. pockets. to the position shown for pocket 20a in Fig. 2 and in these positions the lock arm 40 is blocked against movementby the cam 44. When the turret has a full set of pins, the lock arm 40 is free for movement except it is dependent upon the control from the intermediate deck acting through the arm Si) pivotally mounted yat the lower end of the lock arm. The dropping ofthe pins from the turret 1 is caused by the weight of the pins resting on the inner turret part.

shoes `25 acting against the springs 35 to spread the shoes on the inner and outer turret parts apart a distance suiiicient to clear the largest diameter of the pin.

The intermediate :deckZ comprises means for storing a set of pins received from the turret in a predetermined generally triangular arrangement for subsequent release to the pin setting deck 3. rThe intermediate deck has a frame 55 secured to the struts 12 and 13 on each side of 4the alley and has ten-pin receiving pockets formed in a generally triangular arrangement. These pockets are indicated at 56 with the pocket for the number l pin identitied as 56a, the number 2 pin as 56b, the number 4 pin as 56a` and the number 7'pin as 56d.

The intermediate deck frame 55 may have. guide plates extending ,upwardly therefrom (not shown) to aid in guiding pins from the turret 1 to the intermediate deck 2 and particularly the pins for the numbers l, 7 and l0 pin pockets inthe intermediate deck 2.

One of the pockets 56 for the intermediate deck 2 is shown in Figs. 4 and 5 and the structure is the same for all of the pockets 56 except the pocket for holding the number 5 pin` Each pocket has a iixed shoe 6u facing toward the rear of the machine (toward the left as viewed in Fig. l and toward the right as viewed in Fig. 5). This shoe has its sides secured to the frame 55 as by rivets 61.I A .pair of side plates 62 and 63 extend downwardly from the intermediate deck frame 5S opposite from the {ixed shoe 60 and pivotally support a pivot shaft 64 extending through and secured to flanges 65 and 66 mounted on the underside of a movable shoe 67 positioned opposite to the fixed shoe60 and facing forwardly of the machine. The anges 65 and 66 mount a cross pin 67a which is formed to coact with a catch member having a pair of arms 63 and 69, each formed with a shoulder 70. The pair of arms 68 and 69 are secured to a sleeve 71 rotatably mounted on a iixed pin i2 riveted to the plates 62 and 63 of the intermediate deck frame. The sleeve 71 also has a pair of. arms 74 and A'75 secured thereto in spaced apart relation which .attheir free ends are connected by a cross piece 76 .to form a U-shaped member. The arms '74 and 75 support a trigger 77 pivotally mounted therebetween by a pin 7S and the trigger has a downwardly extending end 77a and a sloped face 7712 at the other end which is arranged to abut the cross piece 76 between the arms 74 and 75.

. A spring 80 is connected between the trigger 77 and an arm 81 fastened to the underside of the movable shoe 67 and functions to maintain the end 77b of the trigger in abutting relation with the cross piece 76 and also to urge the movable shoe 67 to a closed pin holding position as shown in full line in Fig. 5. The pivotal movement of the movable shoe 67 in a clockwise direction is limited by engagement of the cross pin 67a with an edge 82 formed on each of the frame plates 62 and 63.

When the catch member arms 68 and 69 are pivoted in a counterclockwise direction, from the position shown in Fig. 5, by means hereinafter described, to the dotted line position, 'the movable Shoes 67 of the intermediate deck pockets are'free to pivot in a counterclockwise direction against the action. of the spring 89 as caused by the weight'V of .bowling pins resting thereon to the broken line position.

The pocket 56 for the number 5 pin is shown in Fig. 6 and is substantiallyv the same as that shown in Figs. 4 and 5 and duplicate parts have been given the same reference numeral. The pocket 56 for the number 5 pin is arranged 'to perform a detecting'operatin to detect )they presence or association'of pins with the intermediate deck 2. The intermediate deck frame plates corresponding to plates `62 and 63 shown in Figs. 4 and 5 have a slightly different formation and one of these plates is shown at 90 wherein an edge 91 of the plate is spaced a greater distance from the shoulders 70 formed on the catch arms 68 and 69 to provide a suicient range of movement for a movable shoe 67b to indicate the presence of a pin in the pocket with the movable shoe 67b still blocked against movement to a pin releasing position. Each of the movable shoes 67 on the intermediate deck 2 has an upper pin retaining position and a lower pin releasing positionspaced a greater distance from the associated fixed shoe 60. In addition, the movable shoe 67b for the number 5 pin pocket has an intermediate detecting position indicating presence of pins in the intermediate deck 2. Although any one of the movable shoes 67 may be arranged to perform the detecting operation, the shoe for the number 5 pin pocket has been selected because of its central location with respect to the turret 1. lAn arm 9S fastened to the movable shoe 67b for movement therewith has a grooved roller 96 at its upper end to engage a control ann 97. The control arm 97 is secured to a pivot arm 98 pivoted at 99 to a post 100 extending upwardly from the intermediate deck frame 55. The control arm 97 has its upper end 101 extendling upwardly to a position adjacent the arm 50 at the lower end of the lock arm 40 in the turret 1. The control arm 97 has a curved surface 102 terminating in a at surface 103. These surfaces are related to the pivot shaft 64 for the movable shoe I67b and the arm 95 so that with the movable shoe in its upper position waiting the entry of a pin onto the shoe, the grooved roller 96 will engage the flat surface 103 and have the upper end 101 of the control arm 97 in its lowest position. With a pin resting on the movable shoe 67b, the shoe will move to an intermediate position, shown in broken line, which will cause the grooved roller 96 to move onto the curved surface 102 which will result in raising the control arm 97 to place the upper end 101 thereof in position to engage the arm 50 and lock the lock arm 40 'from movement so that pins may not drop from the turret 1. If the movable shoe 67b moves beyond the intermediate detecting position to an extreme position for releasing a pin lLberefrom or any position therebetween, grooved roller 96 will still be on the curved surface 102 to maintain the control arm in locking relation relative to the lock arm 40. To facilitate the return of the movable shoe 67b to its pin receiving position and the arm 95 to a corresponding position, an auxiliary spring 105 is fastened at one end to a bracket 106 on the arm 95 and at `its other end (not shown) to the intermediate deck frame 55.

The pin sett-ing deck 3 includes a middle deck 111! to which the frame members 17 are connected for causing the deck to move up and down, a scissors deck 111 mounted beneath the middle deck 110 which supports pin pickup mechanism operative to pick up standing pins when the first ball of a frame does not knockl down all the pins anda forwardly and rearwardly slidable deck 112 positioned above the middle deck. The middle deck has brackets 115 at its front and at each rear corner thereof each supporting a rock shaft 116 having arms 117 pivotally connected at their lower ends to the laterally slidable vdeck 112 as shown at 118. A spring 120 at each side of the deck is connected between a bracket 121 formed on the slidable deck and frame members 17 secured rto the middle deck 110. These springs yieldably urge slidable deck 112 toward the rear of the machine and the lmovement thereof is controlled by 4a cable 122 operated by control means (not shown) which at one end is connectedto an arm 123 secured to the rock shaft 116 at one -rear corner of the deck, as shown in Fig. 1.

"lThe pin setting'deck 3 has ten triangularly arranged pockets arranged to hold a set of pins in the arrangement which the pins have when set on the alley bed and each of the pockets has a fixed shoe 125 mounted on the middle deck and a shoe 126 mounted on the slidable deck 112 for movement therewith. As shown in IFig. 1, the shoes and 126 are positioned close to each other and upon rearward sliding movement of the slidable deck 112 under the control of the cable 122 and under the urging of springs 120, the shoes 126 move away from the shoes 125 to form the pin receiving pockets for receiving and holding pins discharged from the intermediate `deck 2.

VMeans are provided under the control of the slidable deck 112 for causing pins to drop from the intermediate deck into the pin setting deck 3. This means .includes a series of upstanding lugs 130 formed on the slidable deck 112 as shown in Figs. 1, 5 and 6 which are disposed to the rear of the shoes 126 and associated one with each. When the slidable deck 112 is moved toward the rear to open the pockets in the pin setting deck, the lugs 130 engage the triggers 77 associated with the movable shoes 67 on the intermediate deck, to move the triggers rearwardly or to the left, as shown in Fig. 1, and to the right, as shown in Figs. 5 and 6, to lower the catch member arms 68 and 69 to free the cross pins 67a so that the movable shoes may move to pin releasing positions, if pins are resting on said movable shoes 67, or to free the movable shoes for movement so that when pins drop from the turret 1 they will pass directly through the pockets 56 in the intermediate deck and into the pockets in the pin setting deck 3.

The control arm 97 and lock arm 40 of the turret coact to permit pins to drop from the turret 1 to the intermediate deck whenever the intermediate deck is entirely free of pins. The pins will not drop from the turret when pins are resting on the movable shoes 67 of the intermediate deck or when the shoes are in the process of discharging pins therefrom.

Referring to Figs. 5 and 6, each of the figures show the slidable deck 112 in full line position including a lug 130 and in dotted line shown the lug 130 after the slidable deck 112 has been moved rearwardly to engage and pivot the trigger 77. It will be seen that the trigger 77 is pivotally mounted on the arms 74 and 75 for free pivotal movement in a clockwise direction so as to permit the lug 136 to travel forwardly past the trigger 77 when the pin setting deck 3 is raised to the position shown in Fig. 1 after setting pins and during the process of returning the slidable deck 112 to its normal forward position.

It will be seen from the foregoing that We have provided the turret, intermediate deck and pin setting deck arranged in a minimum amount of space. The intermediate deck controls the dropping of pins from a turret which functions to `drop pins by utilizing the weight of the pins and a direct mechanical control is provided to drop pins only lat the proper times. Also provided is la simple, direct mechanical mechanism for controlling the drop of the pins from the intermediate deck 2 to the pin setter deck 3.
