Patent number: 5601300Abstract: A bracket assembly for attachment to a motor vehicle frame member is adapted to support a frame mounted vehicle accessory, such as a step or running board. The bracket assembly comprises a pair of primary brackets, a pair of connecting pins, a support member, a mounting bracket, and a leveling bracket. The primary brackets define surfaces engaging a vehicle frame member without drilling. The connecting pins extend between and connect the primary brackets. The support member is substantially vertical and is supported by the primary brackets and connecting pins. The mounting bracket extends substantially horizontally from the support member to the accessory. The leveling bracket is fixed to the mounting bracket at a point proximate to the accessory and is fixed to the support member at a point separate from where the mounting bracket attaches to the support member.Type: GrantFiled: May 31, 1994Date of Patent: February 11, 1997Assignee: Kenco/Williams, Inc.Inventors: Raymond W.

Patent number: 5292049Abstract: The disclosure relates to a plate driver head and more specifically to a plate driver head for use with a power impact tool. The plate driver head includes a steel head portion and a shank portion which can be received in most commercially available power impact tools. The drive head is provided with supporting gussets on opposite sides of the shank which extend to the upper surface of the head to provide uniform pressure distribution over the entire head work surface. The head is magnetized to hold the workpiece steady while being inserted into a surface. Several embodiments are disclosed, one of which is a flat uninterrupted work driving surface while another embodiment includes a recess in the driving surface to accommodate different configured workpieces without damaging them during the insertion procedure.Type: GrantFiled: December 16, 1992Date of Patent: March 8, 1994Assignee: Kenney/Williams/Williams Inc.Inventor: Rodolphe Simon

Patent number: 4630181Abstract: A lighting fixture consisting of a downwardly opening housing having a plurality of fluorescent lamps mounted therein, a louver assembly substantially closing the open bottom of the housing and dividing its area into vertically open cells only certain of which receives light from each of the lamps, the louvers being of sufficient vertical height to restrict light passing directly through the cells to a restricted primary area of brighter illumination in the room below, and a translucent light-diffusing panel covering the cells of the louver assembly receiving light from each of the lamps. The lamps may be selected to emanate light of respectively different colors, and both the louvers and the light-diffusing panels may be of selectively different tints and colors, so as to impart a novel, decorative appearance to the louver assembly when viewed from outside of the primary lighting area.Type: GrantFiled: July 15, 1985Date of Patent: December 16, 1986Assignee: H.

Patent number: 4087111Abstract: A transfer apparatus for use between a tractor-like vehicle and a trailer-like vehicle connected by a hitch connection means. The transfer apparatus comprises a linkage member attached between the tractor and trailer with at least a portion of the linkage member extending between the tractor and trailer at a position vertical with respect to the hitch connection means. Means in conjunction with the linkage member such as a hydraulic actuator may supply a rigid connection through the linkage member thereby preventing free hinging in a vertical plane between the tractor and trailer at the hitch connection means. The rigid connection may, for example, prevent rear-up of the tractor and shift weight to the rear driving wheels of the tractor.Type: GrantFiled: April 30, 1976Date of Patent: May 2, 1978Assignee: Williams, Inc.Inventor: Willard R.

Patent number: 3948063Abstract: A pattern mechanism for a knitting machine which is adapted to selectively control longitudinal movement of needles in their slots. The needles are provided with jacks in operating relationship thereto for moving the needle in a longitudinal direction. A separate butt element is carried by the jack and is movable relative to the jack both longitudinally and transversely in at least two alternate modes. One of the modes provides lesser longitudinal free movement of the butt element relative to the jack body than the other of the modes. All of the butt elements carried by a series of jack bodies are cammed to the mode which permits greater longitudinal free movement. Selected ones of the butts are moved to the mode providing lesser longitudinal free movement so that only the jack bodies carrying the selected butt elements will be elevated by a raised cam.Type: GrantFiled: October 21, 1974Date of Patent: April 6, 1976Assignee: Scott and Williams, Inc.Inventor: H. Leslie Curtis
