  • Patent number: 4813840
    Abstract: A cassette of conventional form is loaded with a plurality of semiconductor wafers having indexing flats of the known type and placed over three parallel rollers rotatably secured to a frame. The three rollers include a center roller and two side rollers positioned only slightly higher than the center roller such that their rotary motions can be communicated to the wafers by contact, depending on the position of the individual indexing flats. The indexing flats are roughly aligned in downward directions first by rotating only the center roller and after all three rollers are rotated to bring the indexing flats in upward directions, the wafers are more accurately aligned in a downward direction by rotating only the center roller and all three rollers are rotated thereafter for a predetermined period of time, depending on the desired angular position of the indexing flats.

  • Patent number: 4813844
    Abstract: An apparatus for setting an industrial robot at the standard position comprises a block (19) to be measured, which is attached to a top end portion (18) of a wrist of the industrial robot, and a supporting member (23) for the measurement, which is attached to a fixing base (11) of the industrial robot. The block has three planes (20, 21, 22), orthogonal to one another, to be measured, and the block is positioned to the top end portion of the wrist so that the three planes to be measured are set at predetermined positions relative to the top end portion of the wrist. The supporting member has three frames (24, 25, 26) orthogonal to one another, and the supporting member is positioned relative to the fixing base so that the three frames take predetermined positions relative to three-axis orthogonal coordinates predetermined on the basis of the fixing base. By a plurality of dial gauges (27 through 32; 37 through 42), the positions of the planes of the block are measured.

  • Patent number: 4812099
    Abstract: A stacker having platforms movable along a path by chains. Cam followers on the platforms engage a cam surface which controls the platform path. The chains are driven by a motor in a closed-loop system which monitors the platforms and controls their speed. The closed-loop system first decelerates the platforms and thereafter stops one platform in the intercept-ready position. The platform cam follower enters a claw which moves the end of the platform through the stream to collect signatures when the downstream platform reaches a predetermined count and deposits the stack on a turntable. A piston assembly rotates the turntable one-half turn after each deposit. Different pressure values are selectively applied to the piston assembly to slow the turntable before it is halted.

  • Patent number: 4810151
    Abstract: A door transporting and mounting machine is disclosed for transporting an mounting a door relative to a complementary door frame. The machine includes a wheeled supporting frame for portably transporting a door to a selected door frame site. A generally vertically extending column extends upwardly from the supporting frame and includes a carriage mounted on the column for movement between lower and upper positions. Door gripping arms are pivotally mounted on the movable carriage for re-positioning the door between a horizontal transporting position and a vertical mounting position. When the machine is located at a complementary door frame, the movable carriage, with associated door gripping arms, moves the door to properly aligned position for mounting the door relative to its complementary door frame.

  • Patent number: 4810152
    Abstract: Apparatus is disclosed for accurately positioning stickers when stacking lumber. The apparatus provides an unscrambling conveyer that feeds stickers from a bulk supply to a crowder feed conveyer to present a constant supply of stickers to a timed release mechanism. The release mechanism by cam means sequentially presents individual stickers in a timed fashion to an endless distribution conveyer that initially feeds stickers through an upper horizontal feed plane about a curved guide structure, and finally about a second horizontal feed plane below the first. The stickers are maintained in the second feed plane by an underlying bottom shelf structure. The bottom shelf structure feeds individual stickers into a plurality of sticker positioners that oscillate from an upper position downwardly to feed the stickers onto a top of a lumber stack to accurately position them in spaced relation on a stack of lumber therebeneath.

  • Patent number: 4806063
    Abstract: A portable wild game hoist having a multiple section boom which can be assembled and dismantled. The boom is supported at its lower end by a standard trailer hitch mounted on the rear of a vehicle. Straps are secured to the upper section of the boom and terminate in hooks at their distal ends which are adapted to mate with the edges of the fenders of the vehicle. A torsion bar is adjustably secured to one section of the boom so that is bears against the rear body or tailgate of the vehicle. A rope extends from a winch secured to the boom through a pulley at the distal end of the boom. The rope supports a hanger with hooks for supporting the animal from its rear hooves. In a further embodiment, the boom may be supported by a base resting on the ground and stabilized by the trailer hitch. In both embodiments, the boom is comprised of a plurality of mating sections.

  • Patent number: 4806071
    Abstract: A method whereby a pack of metal sheets adhering to one another is suspended on upper gripping elements of an upper vertically-mobile element beneath which is fed forward a lower transversely-mobile element having lower gripping elements. The upper and lower gripping elements are caused to interact in such a manner as to divide the pack into two parts by raising the upper element; and the lower element is backed up so as to feed on to a production line the part of the pack consisting of a single sheet, and/or to feed on to a reject bed the part of the pack consisting of a number of inseparable sheets.

  • Patent number: 4804309
    Abstract: A gripping claw for a backhoe, breaker, or similar device is secured to the end of a boom in a pivotal manner. Attachment is achieved through a pair of plates joined together facing each other, with the claw pivotally mounted at one end in the space between the plates. A piston and cylinder, also mounted in the space between the plates, joins the plates to a second location on the claw, both being pivot connections, so that extension and retraction of the piston causes the claw to pivot between open and closed positions. To install the attachment on a boom-mounted tool, the tool is detached from the boom, and the attachment inserted in its place, with the tool in turn secured to the attachment. The attachment thus serves as an extension, and is readily installed and removed on site.
