Abstract: An apparatus and method is provided for removal of debris and excess material from pottery greenware. The apparatus includes a vertically disposed spindle which is rotatably driven and carries surface abrading means secured to the uppermost end thereof. This abrading means comprises a body of resiliently flexible material such as a sponge which has a substantial number of pores or open spaces and voids distributed throughout its entirety. The abrading means projects radially outward from diamatrically composed sides of the spindle as well as extending a distance above the upper end thereof, thereby forming a surface which, when revolved about the vertical axis, defines a surface that readily conforms to that of the greenware to be scrubbed or cleaned. A water dispensing nozzle is also situated in close proximately to the upper end of the spindle and continuously ejects a stream of water onto or in the direction of the abrading means during operation of the apparatus.

Abstract: A loading dock board or ramp is provided having a counterbalanced, extendable lip incorporating a releasable lock mechanism. The dock board is provided with a projecting lip pivoted to the outer end of a platform and includes mechanisms for automatically raising or swinging the lip to an upwardly elevated or projected position. A counter-balance spring is included in the structure for assisting in the upward swinging movement of the lip and is structurally combined with a lip lock mechanism to maintain the lip in the projected position. This lip lock includes an automatically releasable mechanism which responds to a rearwardly directed force applied to the edge of the lip when thus elevated, to overcome to counter-balance spring and effect release of the lock thereby permitting the lip to swing by gravity to a dependent position.

Abstract: A signal light system is provided for vehicles to indicate the operative condition of the vehicle to another motorist. The signal light system is responsive to acceleration and deceleration of the vehicle in addition to actuation of the braking mechanism in selectively responsive energization of respective indicator lights for each of the three conditions. An electronic control circuit uniquely capable of providing error-free signals responds to a signal input from the brake mechanism for primary control and secondarily responds to actuation of the accelerator pedal for indicating acceleration or deceleration of the vehicle. A pressure responsive switch mechanism is provided for assembly with the accelerator pedal and is the condition-responsive element capable of producing an input signal that effectively eliminates the possibility of generation of error signals by the control circuit.

Abstract: A large game carrier is provided having a structural arrangement readily permitting folding of elements of the unit into a relatively compact configuration for transport. The carrier includes a pivot block having a game engaging hook rigidly attached thereto and a pair of hand-grip or handles hinged to the pivot block for swinging movement relative thereto. These handles are pivoted to swing about parallel axis from oppositely extending positions perpendicular to the game engaging hook to positions mutually parallel to each other and to the hook for transport. Additionally, an eye-bolt is secured to the pivot block at a side opposite the game engaging hook to permit attachment thereto of an elongated rope permitting an additional person to assist in moving and transporting of the game.

Abstract: A collapsible plant support is provided having a plurality of elongated wire-rod legs which are rigidly secured together at one end. Several helically-wound wire springs of normally elongated configuration are also provided with each spring having the opposite ends adapted to be interconnected and thus form circular rings. These rings are positioned at vertically spaced elevations on the legs which are relatively divergent from their connected ends when the plant support is positioned upright on the ground. Each of the elongated legs is formed with longitudinally spaced notches into which the circularly configured wire springs are positioned and supported on the divergent legs having their free end portions inserted into the ground. Collapsing of the plant support for storage is readily accomplished by first pulling the legs from the ground thereby releasing the rings. The rings are then disconnected at their ends whereupon they again assume the relaxed, elongated configuration.

Abstract: A ring and cord puzzle is provided having a rigid base formed with a plurality of upstanding posts and a plurality of rings articuately connected to respective ones of the posts and an elongated loop which is manipulated through the rings in working the puzzle. Each of the posts is rigidly fixed to the base thus forming a very stable platform during manipulation of the loop to facilitate solving the puzzle. The articulted connection of the rings to the posts in conjunction with at least a portion of the loop being formed from a flexible cord permits working of the puzzle.

Abstract: A protective cover is provided for a golf bag with this cover including a dual compartment interior construction. The cover comprises a shell-form body fabricated from a pliable sheet material and dimensionally configured to cooperatively interfit the open, tip-end of a golf bag. Constructed in the interior of the shell-form body which is of elongated tubular shape having a closed end, is a longitudinally extending partition wall which divides the interior into two compartments for receiving the irons and the woods, respectively. A resilient securing cord is provided which extends around the shell-form body and has attachment hooks secured to each end for engaging belt loops or attachment rings fastened to the upper peripheral edge or end of the golf bag. The resilient cord extends across the body in a transverse manner at the juncture of the partition wall to cooperate therewith in maintaining the irons and woods in segregated pockets, particularly if the golf bag should be inadvertently inverted.

Abstract: A deck nailing apparatus is provided having a wheeled carriage for traversing a surfaced structure, and a pair of nail driving devices which are supported by the wheeled carriage in operative relationship to the surface for the driving of nail devices. Control means is incorporated in the apparatus and coupled in controlling relationship with the nailing devices to cause operation of the devices in proportional relationship to the distance traversed by the apparatus. This control means comprises a cam wheel resiliently supported on the carriage to maintain rolling engagement with the structure surface traversed by the apparatus.

Abstract: A fluid flow control valve for automatic fluid level control in a reservoir is provided having a valve chamber with axially aligned inlet and outlet orifices, a valve closure element disposed in the chamber and having an actuating stem projecting outwardly through the outlet orifice, and a float-type lever arm engageable with the actuating stem. The valve closure element is normally maintained in closing relationship to the outlet orifice by the pressurized fluid at the inlet side with the valve designed for operation over a wide range of fluid pressures. Movement of the lever arm in response to the fluid level is effective in rocking the valve closure element through its actuating stem to a position where fluid may flow through the outlet orifice. The lever arm is provided with a weighted float to assure positive operation of the valve in high pressure fluid systems and the lever arm is formed with means readily permitting adjustment thereof to precisely determine the fluid level in the reservoir.

Abstract: A lathe for generating spherical surfaces of selected radiis on workpieces in the usual manner but which is provided with curve-selecting adjustable means for generating aspherical surfaces which deviate from the spherical surfaces in a predetermined relationship. The lathe is provided with the usual spindle which carries the workpiece for rotation about its fixed axis and a feed carriage which carries a suitable generating tool for swinging about a fixed pivot in generating contact with the face or surface of the workpiece. The feed carriage for supporting the generating tool includes means for supporting it for axial floating movement and means for constantly biasing it into contact with the surface of the workpiece.
