Patent number: 4989654Abstract: The present invention provides a woodworking worktable assembly which may be used in combination with a multi-purpose woodworking tool. The worktable assembly includes a worktable having a work supporting surface and an elongated slot formed therein. A guide insert is positioned within the slot and includes a horizontal base portion and opposing side arms for guiding a guide bar portion of a miter guide. Lip portions extend inwardly toward the center of the insert from the upper ends of the arm portions and serve to prevent the miter guide from being lifted vertically away from the slot. In addition, the base of the insert is spaced from the lower portion of the slot by foot portions extending along the length of either side of the base amd fasteners are provided at the center of the insert for drawing the base toward the lower slot surface.Type: GrantFiled: February 23, 1990Date of Patent: February 5, 1991Assignee: Shopsmith, Inc.Inventor: James E. Berkeley

Patent number: 4967438Abstract: A windshield wiper of the type including a wiper arm having a U-shaped tip end, a wiper blade having a primary lever which has spaced parallel side walls on the lengthwise central portion and a pin extending between the side walls, and a connecting member for connecting the wiper arm with the primary lever and including a main body having a generally U-shaped outer surface corresponding to the U-shaped tip end of the wiper arm, a generally cylindrical bore for rotatably engaging with the pin of the primary lever, and flange portions for slidably engaging with the side walls of the primary lever. The connecting member is formed of two halves being split along a plane perpendicular to the pin of the primary lever, and the flange portions of respective halves for slidably engaging with the side walls of the primary lever are projecting toward side walls of the primary lever at the opposite ends in the lengthwise direction of the primary lever as compared with the lengthwise central portions.Type: GrantFiled: August 21, 1989Date of Patent: November 6, 1990Assignee: Nippon Wiperblade Co., Ltd.Inventors: Masaru Arai, Itsuro Saita

Patent number: 4934114Abstract: Disclosed is a kit of low cost, light weight, corrosion resistant components, including a plurality of extruded members, certain ones of which components are factory preassembled into climbable and unclimbable tower units selected one of which are adapted to be rigidly connected end-to-end by overlapping couplings into a tower at an installation site to support a power line or other load. The couplings and the overlapping surfaces of the tower units have teeth that mesh to lock the couplings in place. The tower is specially suitable for erection in confined areas to heights in excess of one hundred feet to support power conductors. A number of components are selectively attachable to the tower in a wide variety of ways to support high tension insulators in suspension and/or cantilever fashion and to anchor guy cabling to the tower.Type: GrantFiled: January 28, 1988Date of Patent: June 19, 1990Assignee: Lindsey Mfg. Co.Inventor: Keith E. Lindsey

Patent number: 4904110Abstract: In a shelving system, a columnar post, an outer plate, and a fastening device for fastening the outer plate removably to the columnar post. The fastening device includes a bolt having a threaded shank and a transverse head, which is integral with the threaded shank, and which includes a longer portion and a shorter portion, and fastener, which is threadable onto the threaded shank. The bolt is adapted to be sucessively inserted through an aperture in the outer plate, inserted through an aperture in a front wall of the columnar post, rotated about the threaded shank in a clockwise sense, and drawn outwardly until the longer portion of the transverse head bears against a curved corner where the front wall merges with a lateral flange of the columnar post, so as to prevent further rotation of the bolt in a clockwise sense. The longer portion of the transverse head is conformed to the curved corner so as to bear in surface-to-surface contact against the curved corner.Type: GrantFiled: June 17, 1988Date of Patent: February 27, 1990Assignee: Unarco Industries, Inc.Inventor: Herbert H. Klein

Patent number: 4901496Abstract: Assembly apparatus for the connection of two roof beams at the level of the ridge, for providing frames and structures, comprises two cast members (1, 1') identical to each other, each being disposed fixedly partially in the interior of the upper end of each roof beam (2, 2'). The cast member (1) is disposed head to tail with respect to the cast member (1') and the two members (1, 1') each have a protruding portion (3, 3') spaced a substantial distance from a recess (4, 4'). The protruding portion (3, 3') of each member (1, 1') engages in the recess (4', 4) of the other member (1, 1') to provide two connections (3, 4' and 3', 4) between the beams (2, 2'), these connections being disposed closely adjacent respective ends of the beams (2, 2') and coacting to ensure the assembly and securement of the roof beams (2, 2') by mere insertion.Type: GrantFiled: July 27, 1988Date of Patent: February 20, 1990Assignee: Bator S.A., Societe AnonymeInventors: Andre Fritz, Jean Gerlinger

Patent number: 4892166Abstract: A device for coupling a front wheel unit of a motorized wheelchair with a rear wheel unit to obtain an assembled motorized wheelchair. Generally the front wheel unit includes a wheel and handlebars or a steering wheel. The rear wheel unit includes at least a frame and a wheel rotatably connected to the frame. The coupling device includes a connector portion at the front end of the rear unit frame, which connector is generally vertically oriented but inclined forward slightly. The front wheel unit correspondingly has at its rear end a connector portion which is inclined forward at approximately the same angle as the rear connector, and sized and positioned so as to telescopically interfit with the rear connector.Type: GrantFiled: May 3, 1988Date of Patent: January 9, 1990Inventor: Edward J. Gaffney

Patent number: 4870711Abstract: A metal foundation for a bed comprises a modular system of components easily assembled without conventional fasteners. The assembly includes parallel tubular side frame members of rectangular cross-section, each having two L-shaped pieces interlocked lengthwise in a sliding fit. Vertical stiffening ribs spaced apart along the inside and outside faces of the rectangular side members add rigidity. A pair of parallel tubular rectangular end frame members similar to the side members are at opposite ends of the foundation. Four L-shaped and tubular corner connectors of rectangular cross-section provide sockets to slidably receive the ends of the side and end frame members at the corners of the foundation. Longitudinal and lateral inverted U-shaped cross-slats slidably fit into corresponding slots in the inside faces of the side and end frame members.Type: GrantFiled: November 14, 1988Date of Patent: October 3, 1989Inventor: Arthur O.
