  • Patent number: 4817736
    Abstract: An improved pneumatic impact imparting tool includes a follower which is slidably accommodated in a recess formed on the inner end part of a rotor in a pneumatic motor. The follower is formed with a projection for allowing a ball to come in contact with a cam face as it is rotated together with the rotor. When the ball reaches the top of the cam face, the follower is displaced in the axial direction and enters a recess formed on the inner end part of an anvil to collide against stoppers in the recess. Thus, rotational movement of the rotor is transmitted to the anvil in the form of intermittent turning movement of the latter.

  • Patent number: 4813319
    Abstract: An apparatus and improved method for transversely cutting strips of deformable material with a rotating cutting blade which is moved generally transversely across the strip at a predetermined rake angle and bevel angle. A vacuum applied to certain chambers of a platen draws the strip firmly against a supporting structure at two locations on opposite sides of a cutting line during the cut cycle. A lubricant is sprayed through nozzles onto the blade as it cuts the strip and blow-off nozzles remove excess lubricant during the cut and return cycles of the blade to prevent contamination of the cut strip edges. A release bar assists in disengaging the strip from the platen after the strip is cut. Grippers remove the cut strip and then an input conveyor advances the remaining strip toward the cutting line where the grippers pull the strip forward to a predetermined position for the next cut cycle.

  • Patent number: 4802392
    Abstract: The panel saw has an upright supporting grid (2) with vertical and horizontal supporting bars (2a and 2b resp.). The pivotable saw unit (6) is attached to a displaceable beam (5).In order to reliably pick up the wood dust which collects behind the panel (P) to be sawed and which according to the invention amounts to 3 to 5% of the total wood dust quantity, a continuous cover element (7) is fixed to the rear side of the supporting grid (2). Moreover, a rotatably mounted spindle (A) with a sealing foil (10) which can be rolled up is arranged in the marginal area of the supporting grid (2). The sealing foil (10) is brought to bear against the panel edge adjacent to it by a counterweight arrangement (G) having tension cables (12, 18).Flow channels (K) are thereby formed between the horizontal supporting bars (2b), which flow channels (K) are defined on the rear side by the cover element (7) and on the front side by the panel (P) and the sealing foil (10).

  • Patent number: 4802538
    Abstract: A hammer for driving a pile into the ground has a cylindrical barrel and an anvil sealed to an end of the barrel, a hammer piston mounted for reciprocation within the barrel towards and away from the anvil, hydraulic cylinders to lift the hammer piston away from the anvil, and a switch, responsive to an increase in fluid pressure in the space between the hammer piston and the anvil, to activate the lift means. The invention includes a method of driving a pile into the ground, in which the pile-driving impact is transmitted to the pile via a confined quantity of hydraulic fluid and the weight by which the impact is applied is lifted, to a position from which to apply a further impact, in response to an increase in pressure in the hydraulic fluid.

  • Patent number: 4794832
    Abstract: An apparatus and method for cutting tubular band stock to produce an elastic band and unbonding the abutting edges of the band is disclosed. The apparatus includes a guillotine-type movable blade which cuts transversely across the tubular stock and band engaging surface proximate the blade which is formed to engage the cut band and shift opposite sides of the stock in a direction along the cut to break any bonds formed during the cutting process. The shifting apparatus is provided by a pair of fingers which engage one side of the band and cooperate with an arcuate surface engaging the opposite side of the band to shift two portions of the band next to the ends thereof toward the middle of the band and thereby effect breaking of the bonds. A reversible blade and reversible shear plate, as well as a lubricating structure and assembly for adjusting the band with which is cut also are disclosed.

  • Patent number: 4793632
    Abstract: A bookmark and page holding device is provided for automatically holding and marking a page of a book. A spring clip attaches the bookmark to the rear cover of a book. A spring-loaded swing arm is pivotally attached to the spring clip at one end and has a page holder plate pivotally attached to the other end. As the book page is turned, the page holder plate pivots up and away from the page, allowing the page holder plate to return to the next page under the action of the spring-loaded swing arm. In one embodiment, the page holder has an arcuate, inwardly curving edge for engaging the edge of the turned page to facilitate its use with lightweight paper. The page holder plate marks the last page being read when the book is closed as well as when opened.

  • Patent number: 4791726
    Abstract: A head-held, pressurized fluid operated, shears unit for use in the processing of poultry and the like. The shears unit has a body member having a weight and size for ready grasp by a user. One of the cutting blades is fixed in position, and the second blade is pivotally-mounted so as to move toward and away from the first blade to effect a cutting action. The motion of the pivotal blade is effected by connecting that blade, through a pivotal linkage, to a reciprocatable piston rod that extends from a forward end of the body member. This piston rod is fastened at a second end to a double-acting piston within a piston cylinder in the body member. A master valve operated by a lever for grasp by a user directs the pressurized fluid to one of two sides of the double-acting piston so as to effect moving of the piston and piston rod and thus opening or closing the pivotal blade with respect to the fixed blade.

  • Patent number: 4791845
    Abstract: A straight line shear has a pair of carriages which support opposed pairs of shear blade assemblies. These carriages are displaceable to shear gobs from molten runners of glass. Each shear blade assembly can be adjusted relative to its carriage, in the direction of carriage displacement, and to this end shear blade assembly guide pins are slidingly received in carriage bushings. These bushings have one axial portion which is press fit into a carriage bore and the remaining portion has an enlarged threaded interdiameter which extends the bushing and hence its life and which enables the bushing to be pulled from its bore by a hand tool having a threaded socket.
