Abstract: This specification discloses four basic embodiments of a safety wheel and tire assembly that is mounted on the rim of a conventional vehicle wheel. In each embodiment, a safety wheel is provided in the form of a two-part safety rim which is erected into a position in which the beads of the tire are clamped against the flanges of the wheel rim and a lubricated rolling surface is provided at a radius appreciably less than the radius of the tire when inflated. Mechanism is provided to adjust the safety rim into a position for installation and removal by applying lateral pressure to the side walls of the tire. Latches hold the safety rim in erected position and are released either by the lateral pressure aforesaid or by a tool that is inserted through a hole in the wheel rim that is normally closed by a removable plug.

Abstract: An emphysema retarding apparatus comprising a tilt board on which a patient may position himself at a rather steep angle of inclination with his head lowermost. A handle bar extending generally parallel to the head end of the board provides leverage to enable a patient to lower and raise the board from and to a generally horizontal position, with little effort, due in part to a container of counterweights. An adjustable stop at the head end controls the maximum angle of inclination.
