(01.273-54) 2 This invention relatesto devices for automat Fig. '7 is a longitudinal sectional detail taken ically removing fallen pins from bowling alleys during play. on the line 1-1 of Fig. 5. The drawings disclose the apparatus arranged An important object of the invention is to re in operative position with relation to bowling pins 8, which, as indicated in Fig. 1. are set in duce to as small a minimum as possible the work required to be done by attendants in bowling al playing position in a pin zone at the rear end of a bowling alley 8. The apparatus includes a car riage l0 and comprises a platform in the form of a metal base plate l2 having at its sides upstand leys where the game sometimes known as ten pins but more often known as bowling is played. A further object, therefore, is to provide bowl-, ing alley equipment which may be operated or controlled by the players themselves for remov ing bowling pins which have been struck down and without disturbing pins which remain stand ing supporting flanges l4‘. Near each end of each ?ange Hi there is pivoted at- l5 thelower end of an adjacent supporting link l6 which is in turn ‘pivoted upon the outer end of a cross rod l8 which is mounted in the lower ends of upper sup Another object is to provide equipment which 15 porting links 20 pivotally connected at 22 to may be automatically moved into position over brackets 24 secured in any appropriate manner to the zone in which the bowling pins are set up an overhead support 25.

Otherwise, the motor 45 may be allowed to pass the sweeps through the pin zones as many times as necessary to clear fallen pins. As indicated in Fig. 5, sweep rods 81 .and sweeps 88, which of bowling alleys, are somewhat longer than ~ 30 those which'overlie the pin zone. This greater length facilitates removal of pins which have As shown, the fallen into the gutters, so that they, as well as sweeps 88 are located along only a portion of other fallen pins, are swept into the pit 52 at the rear of the bowling alley. the respective belts 48, so that, when the sweeps ~88 are in inoperative position, they will be dis posed above the. carriage l0, and also so that, All fallen pins having been cleared, the player operates the electric switch 48 at such time as when the carriage I8 is lowered to cause the to stop the sweep rods 81 and sweeps 88 in ‘the upper position illustrated in Fig. 1. Otherwise, ‘ 8, sweeps will not be present to disturb pins the switch 48 may include automatic means-which which remain standing, whereby the upright pins 40 causes the motor 45- to-be stopped only when may be engaged and clamped in position with the sweeps are-in thevdesired _ upper position. clamping strips 85 ‘to engage the top of the pins out interference. > In connection with the present pin clearing apparatus, its normal inoperative position is illustrated in Fig. 1.
