Patent number: 4348952Abstract: A mechanism for inducing a crossing of one axis of a roll with respect to the axis of a second roll on a calender roll machine, to correct for varying amounts of roll deflection under varying operating loads. The mechanism includes a pair of biased levers which are pivoted on a frame diametrically across from one another against a bearing box on a calender roll. The roll has a mechanism at each end thereof. The levers are biased by incrementally movable pistons which when actuated, swing the respective ends of the calender roll in an arc about its midpoint to effectuate the controlled skewing of its axis with respect to the axis of a calender roll thereadjacent.Type: GrantFiled: January 19, 1981Date of Patent: September 14, 1982Assignee: USM CorporationInventor: Kendrick J. Gooch

Patent number: 4331040Abstract: A gear system adapted to eliminate backlash between a set of reversible gears. The gears are also arranged to perform without backlash when their center distances are changed. One gear of the double helical type fixed to a first shaft is in engagement with a single adjustably secured first helical gear on a second shaft. A biased helical gear is slidably arranged on the second shaft adjacent the first helical gear, forcing the teeth of the biased gear against corresponding teeth of the double helical gear, automatically removing any clearance between them thus eliminating any backlash therewith, which is desirable for gears driving matched rolls.Type: GrantFiled: April 21, 1980Date of Patent: May 25, 1982Assignee: USM CorporationInventor: Archie N. Swasey

Patent number: 4259591Abstract: Wheel type electronic sheet material area measuring machine has means arranged to emit a test start signal, which may be manually operated or automatically operated at a particular stage in the machine cycle, and test means actuated by the signal which cause all of the detecting means of the machine to emit a signal normally indicating presence of sheet material for a predetermined period of such a length that, in the normal operation of the machine, the signalling means of each wheel should generate at least one pulse. Should a pulse not be received from one of the wheels in the allowed time, a signal is given indicating that the machine is faulty. The invention includes means to indicate which of the arm and wheel assemblies is faulty.Type: GrantFiled: February 7, 1979Date of Patent: March 31, 1981Assignee: USM CorporationInventors: Roy Morris, Terence J.

Patent number: 4259590Abstract: Electronic wheel-type area measuring machine has manual or automatic operating means, arranged to emit, at a predetermined point in the machine cycle, a test start signal, the operating means includes test means, which upon receipt of the test start signal, feeds signals to computing means of the machine until the computing means registers a predetermined number whereupon a stop signal is emitted. The test means has duplicate computing means which also receives the test signals until the stop signal is emitted, whereupon the number of signals received by the duplicate computing means is compared with the predetermined number and an alarm signal is given if the number recorded by the duplicate computer means differs by more than a predetermined tolerance from the predetermined number. The counter check system also preferably provides a visual test on a visual test display unit and an output printer.Type: GrantFiled: February 7, 1979Date of Patent: March 31, 1981Assignee: USM CorporationInventors: Roy Morris, Terence J. Pickering

Patent number: 4256968Abstract: Wheel type electronic sheet material area measuring machine comprises means for emitting a test start signal, operated either manually or automatically at a particular point in the machine cycle, and test means actuated by the test start signal to cause material detecting means associated with each wheel to emit a signal normally indicating presence of sheet material for a predetermined length of travel of a conveyor surface on which the material is normally supported, the wheels running on the conveyor surface. Thus each of the signalling means associated with the wheels should, if the machine is operating correctly, emit a number of test signals. The signals emitted by the signalling means of each wheel of a group of wheels are added and compared with an acceptable range of numbers of test signals which would be emitted in respect of that group if the machine is functioning within the predetermined tolerances.Type: GrantFiled: February 7, 1979Date of Patent: March 17, 1981Assignee: USM CorporationInventors: Roy Morris, Terence J. Pickering

Patent number: 4256448Abstract: A roller die apparatus includes a pair of cylinder rolls which are rotatably and obliquely yieldably mounted on a frame disposed on the output end of a plastic extruding machine. The rolls are biasedly restrained in the frame to permit the obtusely directed movement thereof with respect to the direction of extruded plastic flow. This non-orthogonal movement of the cylindrical roller members facilitates adjustment and cleaning thereof.Type: GrantFiled: August 13, 1979Date of Patent: March 17, 1981Assignee: USM CorporationInventor: George E.

Patent number: 4255059Abstract: Improved means for aligning processing members at various positions in processing passages of rotary processors. Essentially, the alignment means (or alignment elements) comprise a non-rotatable member positioned in the processing passage and shaped to at least partially interfere with flow of material in the passage. The shaped member is designed to perform certain processing functions on material in the passage such as blocking, collecting, mixing, spreading, restraining etc. The member is positioned so as to be non-rotative with the passage but is flexibly supported so as to "float" axially in the passage and is self-centering in the passage by hydrodynamic action.Type: GrantFiled: December 20, 1978Date of Patent: March 10, 1981Assignee: USM CorporationInventors: Peter Hold, Zehev Tadmor, Lefteris N. Valsamis

Patent number: 4249279Abstract: An outer molding band for a shoe upper backpart portion molding machine comprises two support portions, each carrying a block of relatively hard rubber, each block in turn carrying a molding cushion which is shaped to the shape of an inner mold. A cover, which acts as a diaphragm, to which air may be admitted, is arranged between the diaphragm and the support portion, to press the block, and thus the mold cushion carried therewith, against the inner form. The two support portions are pivotable inwardly to a position in which the mold cushions supported thereby engage the inner mold, or a shoe upper placed over the inner mold, and where air may be admitted as aforementioned, to apply a molding pressure to that shoe upper.Type: GrantFiled: October 3, 1979Date of Patent: February 10, 1981Assignee: USM CorporationInventor: Gerhard Giebel

Patent number: 4249692Abstract: A more versatile and improved mechanism is provided for internally maintaining can side seams uniformly aligned, for instance as they advance from a forming horn for registration with a molten solder jet or equivalent applicator. In a preferred form an elongated cage-type horn extension comprises circumferentially spaced rods or tubes arranged to progressively deflect successive can bodies thereon radially outwardly from circular to ellipsoidal cross-section. The extension incorporates interchangeable slot formations selectively to accurately guide and accommodate different seam widths. The rods or tubes, when worn from use, may be rotated about their axes to present fresh, unworn surfaces engageable with the can interiors on their side seams. The invention insures uniformity of the soldered side-seam joints and avoids interference with lithography on the can bodies.Type: GrantFiled: June 16, 1978Date of Patent: February 10, 1981Assignee: USM CorporationInventor: Frederick S. Sillars

Patent number: 4246673Abstract: A flexible band for wrapping about a shoe contour. The band comprises an inner and an outer steel band with a resilient insert arranged therebetween. The inner and outer bands each comprise a toe portion and two side portions. The portions of the inner band overlap, and the portions of the outer band do not overlap. The flexible band also includes an innermost shoe-engaging member attached to the steel bands. The shoe-engaging member has a low friction portion at its toe section and a high friction portion on each side. The present construction permits a longer utility to the band while providing improved flexibility therewith.Type: GrantFiled: March 30, 1979Date of Patent: January 27, 1981Assignee: USM CorporationInventor: Rudi Fichtner
