Abstract: A bicycle trailer hitch assembly including first and second hitch members configured as mirror images of one another, the hitch members being adapted and arranged for attachment to opposites sides of the bicycle frame adjacent the rear wheel. Each member includes a body portion having a first projection configured for abutting relation with the chain stay of the bicycle and a second arcuately configured projection for tangentially abutting relation with the seat stay, each of the projections having a fastener arrangement coacting with the body portion and the adjacent stay of the bicycle frame for enabling securing the hitch member to the frame. Both projections extend from the same side of the body portion with the opposite side of the body portion including a slotted socket opening for receiving the ball end of a trailer tongue fastener. The tongue fastener is retained in position by means of a pin passing through the opposing walls of the slot.

Abstract: A brake shoe having a metallic support or backbone member with a brake pad formed of at least two portions, each of a separate compound or composition, with each compound pre-selected to effect a separate result for each of the pad portions. The portions are configured, arranged and dimensioned so that each (and all) pad portions have a braking surface in contact with the rim generally simultaneously. The partitioned brake pad is formed of different combinations of multi-rubber or elastomers, not a particular combination, to improve wet and dry braking with one pad or the same pad. The selection of multi-rubber or elastomers could be used to stop squealing and grabbing, while also giving the pad stopping power at the same time; or a different combination could be used in wet and dry conditions, or a combination of compounds may be utilized for different partitions for racing conditions, or the like.

Abstract: A lightweight two-wheeled trailer with demountable bicycle type wheels, a removable flexible cloth-like seat, removable upper and lower flexible (and at least partially light-transmitting) weather covering, a removable tow arm and a collapsible frame assembly. The frame assembly includes a structural tubular frame supporting removable wheels with the axles canted so that the wheels are downwardly divergent relative to the ground. The frame assembly includes generally U-shaped support with first and second upright articulated rear tube assemblies coupled intermediate the support and the frame, the tubular members of the frame assembly being configured and dimensioned to define a seating area for one or more infants or toddlers. A depending generally U-shaped tubular ground brace is affixed to the front bar of the support frame, to serve both as ground support (when needed), as well as to define a foot well area for the occupants.

Abstract: A bicycle brake shoe assembly for eliminating the need for readjustment of the brake pad relative to the rim upon replacement of a pad with a like pad and having an elongate tubular stem secured with an opening in a stem clamp device of a brake lever, and an elongate brake pad. One end of the stem and an adjoining surface of the pad are provided with matingly configured portions for providing a fixed orientation of the pad relative to the stem. A bolt passes through the bore of the stem into engagement with a threaded opening in the adjoining surface to hold the parts together. In one embodiment, the parts are formed with an oval, or non-circular recess in the adjoining surface with the end portion of the stem being matingly configured. In another embodiment, the pad is provided with a generally cylindrical stub with a threaded opening, the stub having a diameter generally equal to the diameter of the stem. With the adjoining ends being V-shaped, one male and the other female.

Abstract: A brake shoe having an elongate generally clam-shell shaped metallic support or backbone member, the leading edge of which is provided with a deflectable tongue portion bent at an angle and flexible relative to the main body portion, with first and second brake pads molded thereabout to provide a unitary assembly, with a fastening member secured generally perpendicular to the main body portion. The first and second brake pads are formed of dissimilar material and separated by a recess or V-shaped notch to permit flexing at the recess. The leading brake pad is formed of a long wearing low friction material, while the trailing or rear brake pad is formed of high friction compound. The backbone member is formed by stamping, with the two brake pads molded over the stamping.

Abstract: A bicycle brake assembly including a brake shoe member having a molded metallic backbone member formed as a framework of elongate generally rectangular form with a structurally reinforced portion having an aperture therethrough for receiving a stud member therein. The reinforced portion is provided with a concave surface surrounding the aperture, with friction pad brake shoe material molded about the backbone to form a brake shoe member. A washer having a matingly configured convex surface coacts with the concave surface during assembly to the arm to provide for adjustment.

Abstract: A bicycle brake assembly having a heat sink member with generally disk-shaped fins, the member having a planar surface for abuttingly engaging a coplanar surface of a brake shoe member, the brake shoe member having a friction material molded on a thermally conductive support disc configured for thermal engagement with the heat sink member. The heat sink member has an aperture extending therethrough for receiving the stud of the brake shoe member with the parts being separable so that the heat sink member need not be discarded on wearing out of the friction material of the brake shoe member. The aperture of the heat sink member is preferably threaded to maintain a thermally conductive path between the coplanar surface of the brake shoe member and the heat sink surface. The heat sink member provided with a concave recess about the stud, with a first washer member having a matingly configured surface while pivotally engaging the recess.

Abstract: Apparatus, adapted for use in explosive as well as nonexplosive atmospheric environments, for alternately applying intermittent compression to the legs of a patient during surgery, postoperative recovery periods and other periods of muscular inactivity to accelerate venous blood flow in the lower extremeties and inferior vena cava and thereby prevent blood clotting in these vessels. A pair of double-walled pneumatic leggings adapted to extend from the ankle to the knee of the patient are provided for fitting on each leg. Each legging is connected by a separate conduit to a non-electrical regulating and timing control circuit adapted to receive compressed air, oxygen or other pressurized gas from any available source and transmit it by means of periodic intermittent pulses alternately to each legging.
