Abstract: An apparatus for storing and individually dispensing cans or other similarly shaped objects. The apparatus is of tubular construction with a resilient dispensing-type outlet in the form of a slot near the lower portion of the tube to allow a can to be removed. A stop member is provided in the tube interior opposite the slot to contact the can between the center of gravity and the edge of the can to tilt the can forward in the slot.

Abstract: A cable car or the like, operable by either muscular or electric power -- e.g. by a stationary motor -- is provided with a railway having a runway whose side walls serve to guide the car during travel along the runway, as well as with an abutment for abruptly ending said travel at the edge of a pool (automatic cut-off means being actuated just prior thereto), while a diver who has derived momentum from belly-down riding on top of the car is consequently propelled outwardly over the pool along whatever trajectory may have been pre-calculated. Although applicable to living divers at recreational pools, the invention is primarily useful for an unlimited range of diver tests via use of midget-size facsimilies of human divers, e.g.

Abstract: This invention concerns itself with a swimming pool bottom or floor and an auxiliary floor suprajacent to at least a portion of said bottom or floor wherein the auxiliary floor comprises rigid polymeric foam having a density less than that of water, said swimming pool being further characterized by means to prevent the peripheral portions of said auxiliary floor from undergoing lateral, upward or downward displacement during use, thereby permitting fracture of other portions of said auxiliary floor to occur during downward displacement consequent on impact from the body of a descending diver.

Abstract: Novel baffles are provided for safeguarding divers from severe head, neck or back injuries due to unexpected collisions with bottom walls of pools, and operate on the principle of "rolling with the punches" rather than taking them head-on, with the buoyant force of the layer of pool water immediately underlying the frontward platform-like impact-receiving portion of the baffle serving to cushion the downward or downward-frontward tipping movement which results from collision therewith of the body of a descending diver and aid in returning said platform-like portion to its initial position; whereby difficulties with excessive rebound or whiplash action of the baffle are obviated.In step-wise series or cascades, two or more may act sequentially and independently, so that rebound force generated by one comes too late to affect the diver, his body meanwhile having passed out of range of such rebound force and into cushioned contact with the next.

Abstract: Novel frontward-rowing boat-spanning crisscrossed angular oars having many unique advantages over usual oars are mounted on an optionally portable crossbar disposed athwart the gunnels of a canoe, dinghy, skiff, or other rowable craft, the crossbar carrying carom-type shields to insure against intercontact between oars and boat structure or accessories in case of extremely abnormal or excessive submergence.

Abstract: The invention provides novel safety baffling or baffles for placement in swimming pools at loci underlying the forwardly protruding fronts of poolside slides, diving boards, and diving platforms, and extending any desired distance rearwardly of said fronts as well as forwardly thereof at least a typical diver-body length of 3 to 5 feet but advantageously more. Advantageously each baffle comprises a relatively dense and slippery skid-surfaced lamina carrying "streamlined" slippery-surfaced, cushioning "shingles" plus a less dense subjacent cushioning medium or lamina, e.g., of polyurethane foam or the equivalent, so placed as to obliquely, i.e.
