  • Patent number: 5222998
    Abstract: A device can be provided in different embodiments for holding different tensions in different length string sections of a sports racquet stringing bed. In one embodiment, a strip of material is applied on the periphery of the head portion of the racquet and is compressed under the string portions extending between pairs of adjacent stringing holes. In another embodiment, the tension holding device is a plurality of cylindrical bands of compressible material which fit about the string portions and within the grommets of the racquet. In both embodiments, the material is compressed by the string portion to generate sufficient frictional force therebetween to prevent slippage of the string portion relative thereto and thereby hold the different length string sections under the predetermined amount of differential tension.

  • Patent number: 5201157
    Abstract: A pole top cover assembly includes a generally flat cover plate adapted to overlie an open top end of a tubular hollow pole, an elongated arcuate-shaped bracket formed of yieldably resilient, semi-rigid, semi-flexible deformable material and being disposable along one side of the cover plate, and an elongated fastener rotatably mounted through both an aperture in the cover plate and a hole in the bracket and having external threads threadably engaged with portions of the plate and bracket which form the respective aperture and hole thereof. Rotation of the fastener in one direction relative to the cover plate and bracket causes the arcuate-shaped bracket to engage the plate and to deform and draw toward the one side of the cover plate and thereby expand in length and forcibly engage at opposite ends with portions of an interior surface of the hollow tubular pole so as to retain the cover plate on the pole top end.

  • Patent number: 5158312
    Abstract: A carrier device for transporting sheet material on edge includes a flat bed disposed horizontally when the carrier device is in a transport position, a carriage having a single swivel-type caster wheel underlying and supporting the bed at one end portion thereof for movement across a surface, and a pair of sidewalls attached lengthwise on the bed and laterally spaced from one another to receive a lower edge of the sheet material between them and having sufficient height to laterally confine the lower edge of the sheet material so as to prevent it from being inadvertently pulled or pushed off the bed. The bed has a pair of opposite side edges extending from the rear to a front end thereof and converging toward one another such that the bed side edges and caster wheel cause movement of the carrier device sideways away from and around an object in its path upon engagement of one side edge of the bed with the object.

  • Patent number: 5088199
    Abstract: A suction attachment for a hair grooming clipper includes a suction head having a vacuum relief port and a flexible sealing lid for covering the port. The relief port communicates between an internal air flow passage in the suction head and the exterior of the suction head. The sealing lid is movable by a user's finger to regulate the degree of relief of the vacuum provided by the port. The suction head has a flow constriction defined in the air flow passage midway between a front inlet and a rear outlet and proximate the location of the relief port such that regulation of vacuum relief occurs at the region of the passage where the air pressure is highest and air velocity is lowest. Also, a hollow tubular extension at one end can be inserted in the relief port when the port is completely open to prevent clogging of the open port by hair entering the port from the exterior of the suction head.

  • Patent number: 4997186
    Abstract: A racket frame, such as for a tennis racket, has a head portion, a handle portion and a throat portion extending between and interconnecting the head and handle portions. The head portion encompasses an open region and has a plurality of stringing holes for attaching stringing to the head portion and across the open region. The throat portion is in the form of a pair of legs in a generally V-shaped configuration. Different cross-sectional dimensional relationships are incorporated in the racket frame to tailor racket frame stiffness. A first cross-sectional dimensional relationship relates to location of the maximum cross-sectional height of the racket frame in a lower extent of the head portion thereof so as to define a dual reverse tapered profile along the cross-sectional height of the racket frame.
