19 Claims'.

The invention relates generally to a for a bowling alley pin setter of the which an attendant places the pins in a carriage or frame of the setter and then by appropriate actuation causes the Vsetter to place the pins on the spotsV on the bowlingv alley bed.

A general object of the invention is to yproand more particularly to'a.

vide a pin setter oi' new and improved construction, having a minimum of operating parts so as to permit of economical manufacture and to be free of disorder, while providing an improved pinsetting operation. f

A more particular object of the inventionV is to provide a simplied pin setter of the manumanually actuated type, inV

pin setter aliy actuated type in which lowering of the setter carriage, as well as placing` of the pins, is accomplished by actuation oi' the setting mechanism by power supplied by the attendant as distinguished from actuation as an incident to setter on the bed. Y

provide a pin setter of new and improved construction in which the pins are spotted in a quiet manner and causing a minimum 'of wear on the pins and the alley bed. f

A further object is to provide a pin setter in which the pins are placed and not dropped upon the alley bed.

Still a further object is to provide a Apin setter, which places rather than drops the lpins upon the alley bed, in which the spotting means engages the lower portion only of the pins.

Another object is t provide a pin settingmachine-having pin settingmechanism which, in

supports the same until' the placing of the pins, substantial contact thereof with the bedyand thereafter imparts a lift to the pins toeliminate or reduce t a harmless degree any scraping of the bed by the pins.

Another object chine in which the pins though set maybe readly returned to the pockets in the frame by a simple tipping of the pins by the attendant.

Yet another object is to provide a pin setter, in which lowering of the setter carriage and setting ofthe pins is accomplished by manipulation of a common'handle, having means for preventing discharge of the pins during the initiation of carriage movement.

Still another object is to provide one-piece jaws which may be formed in a single stamping operation.

i Suitable mechanism is: provided for appro- Y".priately*interconnecting the several :laws and for effecting their control from the actuating means I9. Suchmechanism includesa rockable main shaft 55 (see Figs. 3, 11 and 12) extending transversely of the frame I8 and journaled in the castings 25'. At each end, the shaft 55 has pinnedthereto an arm 56 which serves as the connecting mediumbetween the shaft and the actuating means I 9, as will later appear. Also pinned to the shaft 55 for rotation therewith are a plurality of cranks 51, each having an arm 58 and an arm 59 extending almost diametrically opposite to one another. These`V` cranks 51 all have the same Vangularposition relative to the shaft 55 'but are spaced vlongitudinally thereof so that one is positioned between each the rst and second, the second and third, the fourth and fth, and the sixth 4and seventh longitudinal rows of pockets'38', counting from the left in Figs.V 2 andA 11.l Pivotally connected to the arm 58 of each'crank 51'is a driving link 60 the other end of whichis pivotally connected as by a pinv 6I to a tub 43 of the front jaw 40 of the rst pocket, forward of the crank. .This ljaw isin turn connected to the front jawnof each of the pockets in adjacent'rows by aconnecting link 62.V In this manner all of the front jaws 40 are interconnected for simultaneous action.

sleeve 85, so as to be actuated by the actuating meansv I5, as will presently appear.

As previously stated, it is a feature ofthis machine that both the vertical movement of the carriage I8, as well as theactual pin set-` ting, are effected through actuating means I8,V under the control ofthe attendant or pin boy.4

To that end, the actuating means I8 is given a unique construction having no direct connection with the carriage I8 but serving to actuate the carriage I8 throughV the resistancev to actuation of the pin setting 'mechanisnn Accordingly, there is provided at each side of the machine a toggleA mechanism ,comprisinga bent lever 80 (Figs. l', 5, 7 and 9), having a flr'st portion 88. and a second portion 88"` making aan. angle of approximately 55 with the first portion. This lever is pivoted at the free end of its rst por# tion to depending ears 8| of a collar 82 clamped onto the cross-baril rand extends rearwardly from that point. In the normal position of theA lever 80, that'is, when the frame I8 is in the raised, inactive position (Fig. l), therst por- The front jaws 40 are yieldably urged to an open 'Y orvnormal position by'a large tension'spring 63 which is anchored at one end to the frame lI8 and at the other end to' an arm 68 pinned on the shaft 55.

Loose on the shaft 55 near one end thereof is Ya sleeve 65 having at its outer end an oiset crank arm 66 with a lug 61 at its free end projecting laterally into the plane of but radially'beyond the end'of the a1'znf56z Y Also onV the outer end of the sleeve 65 is a second arm 68 whichprojects vertically. 'I'his arm has at its free end (see Fig. 3) a slot 68 in which is received a pinV 18 carried by an'upstanding ear 1I of a driving link 12. 'I'he forward end of the'link 12 is pivotally connected to the rear jaw 4I of the adjaicent pocket by a pin 13 welded to the jaw. The

rear end of the link V12 is formed withY an elongated longitudinalv slot 14 and receives a pin 15 carried on the endof armillv of crank 51, thus having a lost motion connection withfthe `main shaft 55 and providing for movement of the rear jaw independently of the front jaw. Jaw 4I, to which driving link 12 is connected, is

lin turn connected by pin 13 to a connecting link 16 engaging similar pins 13 on the rear jaws 4I of the remaining pockets in longitudinal rows six and seven. A tension spring 11 is anchored at one end to the frame I8 and at the other end to the pin 10 on the link 12, thus tending to rotate the sleeve 65 in a counter-.clockwise direction, as viewed in Figs. 3 and: 6, and moving the rear jaws 4I to fully open or normal'position. Such position is determined by the lip I8 on the rear jaw 4I striking the chute-39. The proportioning of the parts is such that when the rear jjaws are in fully open position the pin 15 on arm 58 is just shortvof the forward end of the slot 14, asclearly seen in Fig. 6.

At its innerV end, sleeve 65 has an arm similar to its arm 68, and this arm is connected by similar linkage to the shaft and to the rear jaws 4I of the Vpockets in rows four and Yve. At the left endof the shaft 55.is a sleeve 18, similar in lall respects to the sleeve save that it Visl shorter. This sleeve controls Vthe rear jaws 4I of the pocketsin rows one, two and three and,v in particular, has an offset arm 66 the same as Should the link 83 now tend to move downwardly through the slot, the roller 88 would strike the,

Pivgtally attached near the free end of portion is one end of amain actuating linkp83 which vpasses through a T-slot 84 (Fig, 4) in the top of lthegcarriage I8 and is pivotally 4connected Y to the encor armzrs. Pivotauy attached to 1the lever 88 approximately at the juncture of the portions thereofis one end of an auxiliary actu-A ating link 85, the other end of which is pivotally attached to.V a slide 86 mounted on the link 83.

Conversely, during the initialV portions of the down movement of frame I8, the linger 81 is withdrawn to permit spring 11 to swing jaws 4I to full open'position conditioning the pockets iorwthe` reception of standing pins. The Vexact point of engagement f and disengagement of finger 81 with ann 56 is shown inFigs. 3, 5 and 6. s

As stated, the frame I8 is actuated solely through the vresistance to actuation of the pinV setting mechanism. In4 order, therefore, that a.

sudden application of force to the lever 80 for the purpose of initiating down movement of. the

frame I8 Vmay not actuate the setting mechanism prematurely, suitable safety means are provided. Herein this means takes the form of a roller 88 carried by the linkVK 83fatapoint just above the top of frame I8 when in normal, raised position.

thus free to pass therethrough. APreferably there is secured beneath the top'of'the frame I8 a rearwardly inclined cam block 8| which prevents the roller 80 from engaging beneath the top of frame I8. The link 83 also carries a pin. 82 (Fig.

While there iene direct connection between the shaft y55 and the rear jaws 4I', these jaws are not actuated simultaneously with, the front jaws 'v LII-through themedium of thepin 15. carriedron` the arm 59 vof `thecrank 51. As previously stated,V

isi ,positionedgsubstantially in "contact with the4 Ypinj|5so that'rotation of vthelcrank 15T-ln al clockwise direction will cause theV pin 'I5 to ,strike the end of the slot and actuate the link 'I2 in a` that the' baseof the pin leaves the pin base rest` 36,' andrrais the pinoijoi the edge *of* the chute 39. These points ofy engagement arehigherfup on the pin thanare/the-points of 'engagement of thefront jaw 40,!so thatthe jointV action of fthe jawsv will effect .an 11p-ending or righting of the Vpirn/but,Y are below' the maximum diam- Yeter` of the pin so vthatthe tapering portion of the "pino bearingfagainst ther bead-41 acts as: acain` tending to imparta liftto the pin. As` aresult thereof, .though .the pin` would, `during, a: slow` setting thereof, s'crapethealley bed, during a proper rapid,` setting,,thecglift imparted by the jaws and 4I suflicient to raise the pin Vthe that the jaws `4I are swungto.

I have perfected a pinsetting machine havingA slight extent required to prevent any detrimental lscrapingof the bed by the pin, with its re- `su1tan wear .on the pin and the bed. with the completionof such nal rapid movement of thehandle 94, the pins are spotted on the bed y -bythe shield 39'. The pins are now properly set and the frame is ready yto be returned to its raised, inactive position.

During such return movement, the sequence of operation is, of course, just the reverse of that during the downward movement. As a consequence, during the initial upward movement of the handle. 94 and prior to any upward movement of the frame I8, the jaws 40 and 4I are returned. to their fully open position, releasing the pins I6 and freeing the frame for upward movement without disturbing the position of the pins. Thereafter, the frame I8 moves upwardly, while the pin setting mechanism remains in the position shown in Fig. 6, until the carriage and the actuating means ISreaches the position illustrated in Fig. 5, that is, where the ringer 81v again contacts the lever 66. During the remaining iinal portion of the yupward movement, the finger 81 now again rotates'arm 66 causing, the rear jaws 4I to be swung tothe positionshown in Fig. 3, wherein they prevent any accidental dropping through the` pockets of the pins during the loading of the frame.

Y When the attendant accidentally` sets the4 pins with some pins remaining standing and while the bowler is still entitled to another ball, a resetting of those certain standing pins only and removal of the remaining pins is required. Such re-setting of the standing pins-and removal of the remaining pins is herein readily effected, because of the support of the pins by the pin base rest 36A so closely adjacent the alley lied.l `As clearly seen in Fig.,8, when a pin standing on the alley bed is tilted rearwardly for the p vose of causing it to assume its normal, reclining position in the pocket I8, the forward edge of the base of the pin is raised above the lower edge of the pin base rest 36 long prior to the time that the forward edge of the pin is" in contact with the pin`base rest 36. As a result, in the continuedforward movement of the pin base, as an incident to tilting to reclining position. there is no possibility that the pin will strike the lower edge of the rest 36, but on the contrary the base of the pin moves easily and uninterruptedly onto the rest. Thus, to return the pins from a standing position resting on the alley bedl to their reclining position in the frame ready to be lifted with the frame, it is only necessary for the attendant to swing the pins to such reclining position, and there is no need that the pins be lifted even the slightest amount. Once the desired pins have been returned to their position in the pockets, the frame may be raised with certain of the pins left standing. This setting of Va few number of pins is thus readily accomplished without any lifting of the pins and without any necessity of the attendant to crawl underneath the frame and reset the pins by hand.

many unique features' and many vimprovements in construction and operation. With the p in setter herein disclosed, the pins may beset very quietly without dropping the pins any considerable distance, which results in loosening of the spots cnthe. alley bed, rand without detrimental scraping of the lbed by thel pins, which also tends to loosen-the spots and to round the edges of the base of the pins,'making the same less stable. 'Moreoven this is accomplished 'with a machine having a simplied construction resulting in a minimum number of parts which may become out of adjustment, resulting. in economy of manufacture. Thispin setting machine, moreover, does not mar ordiscolor the neck` ofthe pins, but effects setting of the pins without engagement ofthe neck thereof. Numerous other advantages and featureswill be readily apparent from the study of the foregoing disclosure.

I claim Vas my'invention:
