Patent number: 5263230Abstract: An improvement in cam operated clamps for clamping heater elements to the nozzles of injection molding equipment. The clamp is adjusted by the rotation of a cam shaft parallel to the nozzle axis. The clamp housing consists of a circular cylinder with a longitudinal slit. Journals for the cam shaft are mounted on one side of the slit and the cam follower is mounted on the opposite side of the slit. Adjustment of the cam shaft increases or decreases the width of the slit providing the clamping action. Attached to the clamp housing is a tab which stops the cam pin rotation at an optimum position just beyond the position of maximum clamping effect. This position provides substantially the maximum clamping effect available from the clamp and effects a torque on the cam pin which holds the cam follower against the stop tab locking the clamp in place.Type: GrantFiled: June 26, 1992Date of Patent: November 23, 1993Inventor: James E.

Patent number: 4442155Abstract: A longitudinally divided cable sleeve characterized by a strip-like sleeve member which is composed of a heat-shrinkable material and has two longitudinal edges with reinforcing inserts to form first and second edges with reinforced portions, and coacting closure elements for joining the edges together with the elements on the first edge being bent from strips of material and having a head portion that is received in a slot or opening in the second edge. Preferably, each of the elements bent from a strip of material has a link portion, which is received in a slot of the first edge up to an abutment surface and a projecting closure part which is inserted through the opening of the second edge is provided with a latch element to prevent accidental and unintentional disassembly of the closure elements after the projecting closure part is inserted through the opening of the second edge.Type: GrantFiled: November 24, 1982Date of Patent: April 10, 1984Assignee: Siemens AktiengesellschaftInventors: Johann Foertsch, Hans-Juergen Meltsch

Patent number: 4186468Abstract: A ring clamp has a pair of flexible sheet-metal strips formed into a ring with one end of each strip juxtaposed with the one end of the other strip, and the other end of each strip lying intermediate the ends of the other strips. The buckles are each formed of a pair of sheet-metal parts one of which has ends bent over and formed with channels into which fit similar channels of another latch part whose ends are in turn bent over the first part for locking-together of the entire buckle into a rigid unit without the use of welding or rivets. Furthermore each buckle has inwardly directed teeth that can bite into the object being clamped. When the ends of the clamp are drawn together to tighten it around an object the two buckles are tightly pressed against the object and prevent sliding of the two strips relative to each other.Type: GrantFiled: May 2, 1978Date of Patent: February 5, 1980Inventor: Michel H. Zaniewski

Patent number: 4153228Abstract: A clamp has a first curved portion with one end connected to a second curved portion which overlaps or surrounds a segment of the first curved portion including the free end thereof. The free end of the second curved portion is connected to an extension, which has an elongated slot adjacent its end and an inclined lower surface adjacent its end. A base extends from one of the first and second curved portions in substantially the same direction as the extension and has an inclined upper surface at its end for cooperation with the inclined lower surface of the extension. The base has an opening extending therethrough to receive a screw, which passes through the slot in the extension prior to passing through the opening in the base.Type: GrantFiled: October 3, 1977Date of Patent: May 8, 1979Assignee: General Electric CompanyInventors: Samuel Delserro, Samuel B. Hsueh

Patent number: 4131788Abstract: An electrical heater for clamping round a body to be heated comprises a sheet-like elongate heating element, a housing member against which the element is located, and a continuous band of flexible metal strip formed into two closely-spaced elongate sections joined at their ends by rounded sections. The element is sandwiched between the housing member and one of the elongate sections and that section is slidably attached to the housing member. In use, the heater is located round the body with the housing member in contact with the body, and the rounded end sections of the strip are urged together, for example by a screw cooperating with rollers within the rounded sections.Type: GrantFiled: April 21, 1977Date of Patent: December 26, 1978Assignee: Hedin LimitedInventor: William J. Fulbrook

Patent number: 4128921Abstract: A tension strap to be circumferentially positioned about a body to be tenned includes a strap member and a plurality of longitudinally movable tension blocks carried on the inside circumferential surface of the strap member for engaging the body. Means for maintaining each of the tension blocks in a defined predetermined position relative to the strap member is provided and includes at least one pin fixedly carried by either the tension block or the strap member and extending through a guideway in the other, and an elastic member such as a spring or elastomer acting on the pin of each tension block against longitudinal movement to predetermine its position relative to the strap member.Type: GrantFiled: December 2, 1977Date of Patent: December 12, 1978Assignee: Messerschmitt-Bolkow-Blohm Gesellschaft mit beschrankter HaftungInventors: Horst Heinze, Gunter Stierle, Ernst D.

Patent number: 4123026Abstract: A device used for removably attaching a strobe to a camera comprises a clamping band provided with a reinforcing plate and adapted to grasp the pillar-shaped grip of the strobe. The larger open end of a box attached to the camera has edges shaped to engage the pillar. The opposite end of the box is provided with inclined surfaces engageable by cooperating inclined surfaces of an operating lever held in position by a bolt which extends through the lever and the box and threads into the hole of the reinforcing plate. The lever has an operating handle which is permitted a degree of angular movement so that when it is turned in one direction the reinforcing plate is drawn into the open end of the box thereby tightening the band against the pillar of the strobe, and when the operating is lever is turned in the opposite direction the band is loosened.Type: GrantFiled: May 16, 1977Date of Patent: October 31, 1978Inventor: Kawazoe Michio

Patent number: 4115904Abstract: This disclosure relates to locks for bracelets, belts and the like to fasten two ends of the same together. The lock basically includes sliders which are attached to the ends of the bracelet, etc., with the sliders having rack formations which are engaged by a single gear to effect the simultaneous inward and outward movement of these sliders. Associated with the gear is a ratchet wheel and depressable keys are provided for effecting the locking, releasing and rotation of the ratchet wheel and the associated gear.Type: GrantFiled: March 18, 1977Date of Patent: September 26, 1978Assignee: Zwyro A.G.Inventors: Robert Zwyssig, Bernhard Tesch

Patent number: 4103826Abstract: A heat exchanger with a tubular body having helical ribs about its periphery constituting expanded interior and exterior conductive heating surfaces. A clamp is captively held to the tubular body for mounting the heat exchanger to the exhaust duct of a freestanding heating unit. Hot gases passing through the exhaust duct conductively heat is the expanded surface of the tubular body and air therein. A thermostatically controlled blower directs the heated air within the tubular body towards a heated surface of the freestanding heating unit for convectively heating the area about the unit.Type: GrantFiled: April 4, 1977Date of Patent: August 1, 1978Inventor: Richard J. Wass
