Abstract: A safety flag bus, which includes a spring-loaded recoil pulley carrying a length of cable extending from the pulley around a bushing attached to the hinge mechanism of a conventional stop arm attached to the bus. The cable extends through one end of a flag storage pipe attached to the stop arm and through a slot in the pipe, around a pulley attached to the flared opposite end of the pipe, to a point of fixed attachment to the bus. A flexible flag rod extends into the flared end of the flag storage pipe and one end of the rod is secured to the cable extending through the pipe, while the other end carries a flag normally located inside the pipe when the device is in retracted configuration. Activation causes extension of the flag storage pipe outwardly of the bus, extension of the cable from the recoil pulley and projection of a portion of the flag rod from the flag storage pipe to extend the flag outside of the flared end.

Abstract: A device that contains a pocket wherein checklist cards can be inserted that match with pushbuttons that are used to indicate completion of certain steps in a series of steps.

Abstract: A device for scoring the opposing sides of a tennis match which is adapted to be mounted on the side of a tennis racket handle. A variation of this device may be employed to keep count of the games won by each side. The device comprises an elongated, flexible, transparent structure which is segmented into two compartments by a seam across its mid section. Enclosed within each compartment is a bead-like chip or marker which is slideably movable therein when the marker is pressed gently. Each chip is held in place by a spring-like action wedging it against the wall of its compartment and preventing it from being moved inadvertently during the game. The structure itself is sandwiched between two strips of film which are adhesively attached together. The outer film layer includes an elongated transparent panel through which each marker may be viewed within its compartment and upon which are imprinted indicia, each of which corresponds to a score in a tennis game.

Abstract: An improved indicia display apparatus particularly useful for displaying indicia indicating the number of down to be played in football competition and locating the position of the ball along the sideline, for example, the apparatus comprising an opaque outer cylinder with a domed top and bottom, with three evenly spaced openings, said outer cylinder fitting over a translucent inner cylinder with two rows of printed indicia. Illumination within the inner cylinder is attached to a center pole that attaches to the domed top of the outer cylinder by a male and female plastic threaded screw fittings. The inner cylinder having a sleeve that slides up and down and rotates on the center pole for selecting desired indicia representing chosen down. Top dome and bottom dome of the outer cylinder are attached to outer cylinder body with metal screws for securing assembly together and removing to replace illuminating device.

Abstract: A viewing glass used through which measurements are displayed which comprises a groove (5) having a shape parallel to the movement of an indicator needle. Displaceable markers are placed in the groove in order to denote the limiting positions of the measurements being made.

Abstract: A pivotal crank is positioned with respect to the output cam of a torque limiter such that upon torque limiter operation the resulting translation of the cam pivots the crank. Attached to the crank is a flag arm which is normally retained by a spring clip. Pivotal motion of the crank causes disengagement of the flag arm from the spring clip thereby indicating torque limiter operation. The flag arm remains in the disengaged position, despite subsequent absence of limiter operation, until it is manually reset.

Abstract: A baseball bat has its handle, shaped to be grasped by the hand of a user, extending on into an enlarged hitting portion that continues away from the handle. Included in that hitting portion is a velocity meter situated in a cavity that extends longitudinally inward toward the handle from the outer end. A plunger is slidably received within that cavity and is resiliently held in place. Also included is an indicator which informs as to the amount of movement of the plunger outwardly from within the cavity as a result of the swinging of the bat by the user.

Abstract: A device for keeping a golf score comprises two flat panels fastened to provide a space in between. The first face is equipped with nine horizontal slots, numbered 1 to 9 and the second face an equal number of slots numbered 10 to 18 representing the holes on a golf course. Indicating runners or slides operate in these slots which are equipped with stops providing spaces and numbers from 0 to 10 for each slot representing the number of strokes per hole. Indicating slots are of novel construction so as to be easily moveable and yet may be readily arrested and held in place opposite the number corresponding to the strokes taken by the player. Numbered wheels are provided for totalizing the score as the game progresses.

Abstract: Apparatus for monitoring razor usage. The apparatus comprises an indicator means supported within a hollow handle portion of the razor and slidable to selected positions along the length thereof for alignment with numbered indicia on the handle to permit monitoring the number of times that the razor has been used.The apparatus provided may be used with razors of either the reusable or disposable type and can be incorporated into such razors with only minor alteration of the razor design.
