Definitions

  • ABSTRACT Apparatus for automatically resetting tethered bowling pins including a tether tension responsive device, a lift mechanism for raising and resetting the pins, a clutch assembly associateed with each tether, and a device for controlling the clutch assemblies.
  • the tension responsive device includes a pawl associated with each tether in such manner as to be disengaged therefrom in response to the tension in the tether which results from the felling of the associated pin.
  • the lift mechanism Upon the sensing of any felled pin, the lift mechanism is operated to raise all of the pins to a standby position.
  • the invention visualizes resetting apparatus which serves to remove toppled or felled bowling pins from the bowling lane to standby positions remote from the field of play, until completion of the frame, the unfelled pins being also removed and subsequently reset on their respective stations on the bowling lane in readiness for the delivery of another bowl by the player. In the event ofa strike on the first bowl delivery, however, the felled pins will be automatically reset for the next frame.”
  • the resetting apparatus is intended for use with bowling pins having flexible tethers by which they are raised to standby positions aforesaid and thereafter selectively lowered and reset on their respective stations on the bowling lane as described.
  • the resetting apparatus visualized herein is automated to include means accompanying each tether for sensing felling of its associated pin. That is to say, when the pins are struck by the bowling ball they are toppled or felled onto the bowling lane with concomitant stress or tensioning of the tethers attached thereto; the sensing means aforesaid being responsive to such tensioning.
  • mechanism is actuated by the sensing means to initiate a chain of events wherein all of the pins, felled and unfelled, are elevated by their tethers to said standby positions, the unfelled pins being then lowered and reset on their respective stations while the toppled pin or pins, as the case may be, remain behind in standby position; the invention being principally concerned with the latter function of the resetting apparatus.
  • the invention also visualizes means for automatically resetting the felled pins when the full complement has been felled.
  • the invention embodied herein distinguishes markedly from the prior art by the fact that the toppled pins, once they have assumed their standby positions, are retained therein by a simple wedging grip on their tethers. More expicitly, the resetting apparatus" includes means for grasping and pinching the tethers of the toppled pins when they are in standby position to thereafter inhibit resetting of the toppled pins on their respective stations until completion of the frame.
  • a broad object of this invention is to provide resetting apparatus for tethered bowling pins of the character described in which pins that have been toppled in play are automatically retrieved and held in a standby position, remote from the field of play, until completion of the frame.
  • Another object of the present invention is to provide "resetting apparatus for tethered bowling pins which includes means for sensing felling of one or more pins and mechanism actuable thereafter by said sensing means to retrieve and hold the felled pins in standby positions by a simple wedging grip on their tethers.
  • Yet another object of the present invention is to provide resetting apparatus" for tethered bowling pins which includes means for automatically resetting the felled pins when the full complement has been felled.
  • apparatus for resetting bowling pins on one end of a bowling lane having a target area with a group of stations for a complement of said bowling pins at said end comprising: a pin receiver disposed and aligned above each said pin station providing a standby position for the pin normally set on said station; an individual flexible tether for raising and lowering each said pin relative to its said station trained through its respective receiver; mechanism actuable as and when a pin has been felled in play to raise all of said pins by their respective tethers and thereafter to reset tht unfelled pins on their respective stations with the felled pins being raised to and retained in standby position; clutch assemblies respectively movable between a neutral position and a braking position in which the tether of each felled pin is restrained against movement when the latter is in its standby position inhibiting resetting of said pin on its station; means for selectively moving the respective clutch assemblies from braking position to neutral position permitting resetting of the felled pins

  • FIG. 1 The preferred embodiment of the present invention is illustrated generally in FIG. 1 wherein the resetting apparatus A is depicted as being supported over one end of a conventional bowling lane B which includes a target area C on which a group of bowling pins 2 are positioned in familiar triangular pattern; the object being, of course, to topple or fell the pins with a bowling ball delivered by a player at the opposite end H of the bowling lane B.
  • pin group depicted in FIG. 1 of the drawing is constituted by five pins, it should be understood that this is not to be construed as a limitation.
  • each said bowling pin 2 is provided with a flexible tether 4 attached to its apex 6 by which it is elevatable to a standby position above said target area C as illustrated by the dotted line position of a said bowling pin 2 in FIG. 2.
  • the invention contemplates retrieving the felled pins by their tethers and storing them in the aforementioned standby position remote from said target area C until completion of the frame.”
  • the invention further contemplates that the entire complement of pins, both felled and unfelled, will be preliminarily moved towards standby position in which the felled pins alone are retained pending further developments in play, the theretofore unfelled pins in the frame of note being thereafter restored or reset to stand alone on said target area C awaiting the next bowl delivery.
  • the resetting apparatus serves to raise all of said pins 2 simultaneously i.e., both felled and unfelled pins to said standby position, whereby the unfelled pins are subsequently lowered and reset on said bowling lane B with the felled pins remaining behind in said standby position.
  • the unfelled pins are lowered vertically to their play spots or stations denoted by an X on said bowling lane B as in FIG. I; it being understood that said pin stations X are in vertical registration with the respective standby positions there'above enabling said pins 2 to attain play position immediately upon being lowered onto said bowling lane B.
  • Standby accommodation for said pins 2 is provided in this example by a deck 8 supported over said target area C; said deck 8 being apertured as at 10 to provide receivers for the respective pins 2.
  • Each said pin receiver 10 has a diameter which is slightly smaller than the widest diameter of a pin 2 creating an impasse and preventing said pin 2 from passing completely therethrough; it being understood, of course, that pin 2 may penetrate receiver 10 until the impasse is reached.
  • each tether 4 extends upwardly from its associated pin 2 to be trained through a said receiver 10 thereby enabling said pin 2 to be raised by its tether 4 into said receiver 10. It will also be understood that the parts are respectively shaped and proportioned so that pin 2 will seat in receiver 10 when the said impasse is attained at which time the pin 2 is said to be disposed in its standby position in vertical registration with its station X on target area C.
  • its tether 4 may also be guided by a guide 12 provided on a guide plate 16; said guide plate 16 being spaced above and over said deck 8.
