Abstract: An improved revolver hand and hand spring which permits the revolver to accommodate a multiplicity of approximately equal hand lengths.

Abstract: A firearm has an external hammer that is manually cocked in order to rotate the trigger to its ready-to-fire position. The hammer has an elongated vertically extending recess formed therein, such that when the hammer is adjacent the firing pin, an end portion of the recess is juxtaposed to the firing pin, and the hammer does not engage the firing pin. An elongated safety member is disposed within the recess and movable between retracted and extended positions, the extended position being such that the hammer may drive the safety member into engagement with the firing pin, and the retracted position being such that the safety member cannot engage the end of the firing pin but may lodge beneath its under side. A cam carried by the trigger cooperates with the hammer for controlling the position of the safety member. During firing the safety member swings with the hammer, and the firing pin is actuated by the combined kinetic energies of both.

Abstract: A lightweight vehicle which utilizes a single large wheel in the rear that carries most of the weight with a single small wheel in front for guidance. The driver's seat is normally positioned immediately in front of the large wheel and the engine is positioned immediately to the rear of the large wheel, with the center of mass of the vehicle being below and forward of the axle of the large wheel. The passenger seat is connected to a frame extending between the two wheels by a parallelogram type linkage which connects to a bumper extending in front of the vehicle. The linkage is arranged such that on impact of the bumper, the parallelogram linkage causes the seat to move upwardly and tilt backwardly over the top of the large wheel to help protect the driver in the event of a crash.

Abstract: An improved locking mechanism for securing cargo units and the like during transport has first and second complementary locking pawls carrying oppositely directed locking dogs, each pawl being pivotally mounted between spaced side supports for movement from a retracted position to a generally upright locked position. While the first pawl only is biased by spring means towards an upright position, it is held down in a retracted position by retaining portions of the second pawl. As the second pawl is lifted from the retracted position to the generally upright position, its retaining portions disengage from the first pawl permitting the first pawl to pivot upwardly to the generally upright position under the urging of the spring means simultaneously causing both the first and second pawls to move into mutually locking engagement. The spring means biasing the first pawl only is located in a sheltered non-exposed out-of-the way position between the spaced supports and below the upper edges of the spaced supports.

Abstract: An adjustable and convertible piece of furniture for accommodating single or multiple persons in multipositions. The piece may comprise a chair, couch, bed, or recreational support of novel configuration facilitating face to face conversation among several persons sitting, lounging, game playing, TV viewing, snacking, sleeping, or participating in other recreation.A unitary frame supports a cushioned horizontal surface above the floor or ground on a plurality of legs. The frame carries inner and outer tracks depending from its under side, therefrom, with the tracks being outboard of the legs, in spaced apart relation to each other. The tracks support a plurality of backrests, independently positionable along the border of the frame, via outwardly protruding cantilever means extending upwardly as vertical supporting means, in turn carrying horizontal backrest members at levels above the elevation of the cushioned surface. The space above the cushioned surface is otherwise unobstructed.

Abstract: A rocker-type chair is used which is normally unbalanced in a rearwardly reclining direction. A rear support frame has its lower and rearward end in engagement with the floor while its upper and forward end is pivotally secured to the rearward side of the chair. The rear support frame is forcibly pivotally rotated relative to the chair in order to selectively vary the extent to which the chair reclines rearwardly.As the pivoting action takes place, the main part of the chair turns upon its rocker-like members. The lower and rearward end of the rear support frame slides or rolls horizontally along the floor surface. The weight of the occupant of the chair is at all times divided between two forward support points which are provided by the rocker-like members, and a rear support point which is provided by the rear support frame.

Abstract: A reclining chair having seatrest, footrest, and backrest which are adjustable to either a sit-up or a lie-down position or any selected intermediate position, with the entire chair being also adjustable to recline rearwardly at a selected angle. All of the adjustments can be made manually by the occupant while reclining in the chair. The mechanism also includes compensating means to avoid or minimize any influence by a selected adjustment upon a non-selected adjustment. None of the adjustments results in any significant raising or lowering relative to the floor surface of the combined center of gravity of the chair and its occupant, and therefore, in reversing any of the adjustments the occupant is spared the physical work that would be involved in raising the center of gravity.
