Abstract: A body-supporting bed pivotally supported on a frame and juxtaposed circular plates controlling pivoting of the bed by a series of locking openings in a first plate, by a locking pin on a second plate, and by an abutment pin on a third plate disposed in arcuate slots in the first and second plates. A foot-supporting boom supported to extend an adjustable distance from the foot of the bed and a pair of adjustable spaced padded ankle-securing tubes on the end of the boom and a latch for the tubes including a push rod operated latch piece, the push rod having a knob disposed between the legs of the user.

Abstract: Trailer, for two or more vehicles such as motorcycles or three-wheelers, having a narrow tongue extending forwardly from a broad platform, the tongue adapted to support the front wheel of one vehicle in position disposed mostly forward of the platform, a tube outlying and above the tongue and body having fittings for attachments of vehicle tie-down straps. A pivotally mounted rear loading ramp is formed by a first tube bent into a U-shape and formed by one or two other tubes parallel to the base of the U-shape and secured to the arms of the U-shape and legs extending laterally from the base of the U-shape, in an oblique plane, to support the base above ground in the down position of the ramp.

Abstract: Swing axles connected to a transverse rear axle housing by precision pivot assemblies formed in a pair of small vertical plates secured to front and back of the axle housing. Rubber pivot and spring members are received in the inverted U-shaped cross-section of the axle housing and have rests bearing on the middles of the swing axles. The rubber members form pivots for the swing axles and the rests accept fore and aft loadings of the swing axles.

Abstract: Forced hot air circulation is provided for a fireplace by a unit that can be "pushed" into place including a bank of lower tubes that are positioned in the firebox and provide a grate and including an outer housing lapping the margins of the firebox opening and having a lower manifold that feeds the forward ends of the lower tubes and having an upper register that connects to the forward ends of a bank of upper tubes. The lower tubes bend upwardly and are connected by a manifold to the upper tubes. The upper tubes are smaller and more numerous than the lower tubes and are arranged so that gas rising past the upper tubes must follow tortuous paths. Blowers are connected to the lower manifold.
