Patent number: 5037068Abstract: A camera platform is positioned on the upper end of a lifting mechanism formed by a pair of driving cranks where the outer end of the second crank is connected to the camera platform and the inner end thereof is connected to the inner end of the primary crank. The lower end of the primary crank is pivotally mounted on a mobile chassis which includes a hydraulic system for actuating movement of the primary crank. The inner ends of the primary and secondary cranks are connected by a gear train that provides a two-to-one ratio to multiply the angular movement of the first driving crank to generate movement of the second driving crank in an opposite direction but at twice the angular magnitude of movement. The transmission of angular movement upon actuation of the hydraulic system is accomplished by a double jointed parallelogram system forming the driving cranks and connected to the drive gearing.Type: GrantFiled: March 28, 1989Date of Patent: August 6, 1991Assignee: Meccanica Italiana S.r.l.Inventor: Armando Grottesi

Patent number: 5035400Abstract: A tool for the removal of a staple employed for attachment of a cable to a support structure comprises a head member, including a pair of outwardly extending, generally parallel engagement members. The engagement members are spaced apart a distance which is less than the distance between the legs of the staple and which is greater than the lateral width of the cable. A handle member engages the head member in a manner such that the application of a force upon the handle member causes the engagement members to exert a force upon the crown of the staple to move the crown away from the support structure, thereby removing the legs of the staple from the support structure.Type: GrantFiled: February 21, 1990Date of Patent: July 30, 1991Inventor: Paul J. Altenbach, Jr.

Patent number: 5031881Abstract: A hand tool having utility in the extraction of staples, tacks and nails. A thirty degree bend is formed near the distal end of an elongate, rigid shank. The shank widens laterally outwardly distal to the bend, forming a pair of laterally extending wing members that exhibit bilateral symmetry. The shank returns to its original breadth at the distal end of the wings and four parallel claw members extend therefrom. The four claw members are separated by horizontal and vertical slots that divide the claws into a first, upper pair and a second lower pair. The lower pair of claws has a greater longitudinal extent than the upper pair and have a feather edge to facilitate sliding of said lower pair under the crown of a staple. The collective breadth of the lower pair of claws is slightly less than the breadth of a staple so that the crown of the staple is supported at its opposite ends during the extraction procedure.Type: GrantFiled: December 22, 1989Date of Patent: July 16, 1991Inventor: John Thurmston

Patent number: 5018711Abstract: A clamp for use in aligning and installing cosmetic fronts on drawers includes first and second clamp body members which have respective connecting flanges adjustably secured by threaded fasteners. Juxtaposed threaded clamping jaws allow a cosmetic front to be clamped on a drawer face. The clamp is formed from thin sheet metal material and has an offset construction which allows the drawer to be closed with the clamp installed. The thickness of the sheet metal stock material is utilized to determine the spacing between a top edge of the cosmetic drawer front and the cabinet in which it is mounted. The adjustable connecting flanges allow the clamp to clear a "sub-top" which is present in some cabinets, thus allowing the spacing between a top edge of the cabinet top or adjacent drawer front to be precisely regulated.Type: GrantFiled: January 16, 1990Date of Patent: May 28, 1991Inventor: Douglas L. Johnson

Patent number: 5018411Abstract: Multiple-head tool such as a multiple-head screwdriver includes an electrically insulated handle; a shaft which has one end inserted into the handle; a multiple-headed bit which is mounted to rotate within a slot in the other end of the shaft; and an electrically insulated sleeve which is mounted to move along the shaft and to rotate about the shaft. In use, the multiple-head bit is rotated so that the desired head extends outward from and substantially parallel to the shaft and another tool or a spur is disposed within and substantially parallel to the slot. The sleeve is then moved down the shaft to cover at least a portion of the slot to enclose and hold the head or spur disposed therein rotationally fixed.Type: GrantFiled: May 22, 1989Date of Patent: May 28, 1991Inventor: Nathan P. La Padura

Patent number: 5016858Abstract: A hydraulic lift mechanism for raising and lowering heavy loads such as a camper shell above the cargo area of a truck includes a generally planar U-shaped lower base frame attachable to the truck and a substantially identical plan-view shape upper load support frame for attachment to the camper shell or other load. Two identical X-shaped scissors jack-like, lifting structures comprised of two crossbeam members pivotably joined to one another at their centers, and pivotably joined at their forward ends to vertically aligned positions in an upper and lower side frame member, are spread apart by a hydraulic powered cylinder pivotably fastened at one end to a side rail of the base frame and pivotably fastened at the other end to a crossarm, to raise the load support platform.Type: GrantFiled: January 24, 1989Date of Patent: May 21, 1991Inventor: William D. Mitchell

Patent number: 5013011Abstract: A self-deploying stabilizing support jack is presented which stabilizes and positions a recreational vehicle or trailer. The support jack comprises a bracket, a two-way cylinder, lift arms, a stabilizing sleeve and several electrical warning devices and safety features. The lift arms and cylinder are attached to the bracket at separate, offset first and second points so that when the ram of the cylinder contacts the foot of the lift arm, the entire apparatus is raised to a horizontal position. A stabilizing sleeve attached to the lift and surrounding the cylinder stabilizes the device from lateral movement. An intermediate third pivot point in the lift arm helps reduce stress upon raising. Several signalling devices warn the operator when the support jack is in the deployed position. A safety circuit automatically raises any support jack that is not in the horizontal safety position should the ignition be turned to the "on" position.Type: GrantFiled: June 19, 1989Date of Patent: May 7, 1991Inventor: Lowell E. Halloway

Patent number: 5009407Abstract: A surgical table intended specifically for microscopic lumbar laminectomy surgery which may be quickly and conveniently adjusted to fit the needs of the individual patient, and by which the patient is properly positioned for the surgery in a matter of minutes. The table serves to hold the patient in the proper flexed position throughout the surgical procedure. The table includes a top which is supported on a frame base at its forward end by a post in a cantilever configuration, with the top being angularly adjustable about a horizontal axis and also about the vertical axis of the post, and with the post itself being adjustable to set the top to a desired elevation. For the procedure, the patient kneels on a support at the other end of the base with his upper torso extending over the table top to be supported on the top by his iliac crests and chest.Type: GrantFiled: May 15, 1989Date of Patent: April 23, 1991Inventor: Robert S. Watanabe

Patent number: 5007205Abstract: A roller carrying yoke is mounted on the base of the belt sander for pivotal movement about a pivot screw as controlled by the adjusting mechanism which includes a carriage bolt non-rotatably mounted in a slot in the yoke. The slot allows movement of the yoke relative to the bolt. The bolt projects through a hole in the housing and threads into the knob. A spring compressed between the yoke and the housing frictionally loads the knob so it holds adjustment. The yoke moves the roller away from the fixed roller until the roller engages and is limited by a belt. Then the loading spring is stretched to tension the belt. The tension spring force is cancelled out as the lever is actuated to pull the roller back for belt removal. When the cam follower on the yoke engages the cam (operated by the lever) the spring length remains constant and the actuating force is minimal.Type: GrantFiled: June 27, 1988Date of Patent: April 16, 1991Assignee: Milwaukee Electric Tool CorporationInventor: Joseph G. Farmerie
