Abstract: A steerable and brakable sled comprises a body member having a passenger compartment and being mounted to a frame and upon a pair of skis each having a duckbill-shaped forward portion, and further comprises steering and braking controls, the steering controls including a steering member, a pair of steering arms connected to the skis for pivoting the skis on their edges which turn the sled in the desired direction, and the braking control including a braking arm connected to the steering member which is accessibly disposed inside the passenger compartment and connected to a plate-like braking member hingedly attached to the bottom side of the body member at the rear end thereof and having a corrugated edge for engaging the ground once the user pulls back on the steering member.

Abstract: A quick set and release clamping device comprising a frame having an inner leg and an outer leg fixedly spaced from each other, a threaded rod freely movable through a transverse bore in the end portion of the inner leg, a first work piece engaging member fixedly attached to the end of the outer leg, a second work piece engaging member swivelly connected to the threaded rod, a pair of rod engageable half bodies slidable in a tapered end of the transverse bore for engaging the threaded rod, a retaining cover to house and restrict movement of the rod engageable half bodies, a detent to urge the half bodies into the seat portion of the transverse bore and to engage the threaded rod, a spring to urge the rod engageable half bodies slightly out of the tapered end of the transverse bore, a biased element for urging separation of the rod engageable half bodies, and a spring member to urge the detent against the cover.

Abstract: An apparatus for suspending and rotating a boat about its longitudinal axis in either direction, including a pair of movable and adjustable support frames having connecting arms which are designed to rotatably engage the support eyes (also known as ski tow eyes, wench eyes or mooring eyes) on the rear and front ends of the boat. The rear support frame includes a rotatable shaft upon which the rear end connecting arms are rigidly mounted so as to be capable of rotating the boat about its longitudinal axis. The rear support frame also includes a base frame with a pair of extensible legs which are adjustable to support and balance varying sizes of boats. Each support frame includes a hoist for causing vertical movement of the connecting arms which support the boat. The front end support frame is constructed so as to define a passageway therethrough to facilitate removal of the boat trailer upon which the boat rests, once the boat is hoisted therefrom.

Abstract: A method and apparatus for cleaning a surface using a high velocity stream or streams of cleaning fluid. The high velocity stream or streams issue from one or more nozzles that are moving at a high velocity relative to the surface to be cleaned. In a preferred embodiment, three nozzles are mounted to a common hub member with two of the nozzles directed at the carpet so that they tend to move the hub member in a first direction about the axis of rotation. The third nozzle is directed at the carpet so that it tends to move the hub member about the axis of rotation in a second direction opposite to the first. The first two nozzles determine the direction of rotation and the third nozzle is then moved relative to the surface so that the velocity imparted to the stream issuing from the third nozzle because of its motion adds to the existing velocity of the stream due to the high pressure alone of the source of the cleaning fluid. This embodiment has been found to work particularly well on carpets.
