Patent number: 5536136Abstract: A mechanical loading device capable of generating a substantially rectilinear output motion for the purpose of transporting workpieces between work stations. The mechanical loading device is capable of producing the rectilinear output motion such that a workpiece is lifted, transferred horizontally, and then lowered into position with a significant degree of precision. The rectilinear output motion is generated primarily by a carrier on which a yoke is supported with an eccentric shaft extending from a driven member mounted to the carrier. The eccentric relationship between the driven member and the yoke, in conjunction with the controlled rotation of the carrier, generates the rectilinear output motion at an output member supported by the yoke. The mechanical loading device is structurally strong and compact, is constructed so as to be readily maintainable, and enables the efficient conversion of a rotational input motion to the desired rectilinear output motion.Type: GrantFiled: February 3, 1994Date of Patent: July 16, 1996Assignee: Utica Enterprises, Inc.Inventor: Arthur C.

Patent number: 4480506Abstract: Apparatus for generating a lobular polygonal form comprises a first device rotatable about an axis, a second device including a member eccentric to the axis and movable in an orbit thereabout, and a third device responsive to said combined movement of the first and second device for tracing a lobular polygonal form (1) which has an odd number of sides capable of maintaining approximate tangency with two parallel planes upon rotation of said form or (2) which has an even number of sides capable upon rotation of the form of maintaining approximate tangency with three circles of equal diameter and having equidistant centers. The generated lobular form may be traced by a metal-working tool that forms a die cavity in a workpiece. A novel lobular screw blank may be formed in the die cavity.Type: GrantFiled: October 15, 1981Date of Patent: November 6, 1984Assignee: Research Engineering & ManufacturingInventor: Eugene K. Chapman

Patent number: 4472979Abstract: A drive system for a machine including a transmission for converting rotary motion into linear reciprocating motion for driving a rack and a pinion is disclosed for use in connection with moving the pinion in oscillating rotary fashion to be the input for a differential. The differential is selectably controlled to either rotate or remain fixed and permit at least one of its outputs to rotate. The result of the drive system is to either swing a member connected to the differential output which member holds a stack of disc-like objects from vertical to horizontal or alternatively to hold a plurality of such stakes in vertical position and rotate them.Type: GrantFiled: January 28, 1981Date of Patent: September 25, 1984Assignee: American Can CompanyInventor: David L.

Patent number: 4444210Abstract: Apparatus for reciprocating the tubular rod guide which supports the cigarette rod during severing by the orbiting knife of a cutoff has a pair of identical drives whose first driving units receive rotary motion from a common driver gear and transmit torque to eccentrically mounted second driving units. The second driving units support an eccentrically mounted holder for the rod guide. The eccentricity of the second driving units with reference to the respective first driving units is the same as the eccentricity of the holder with reference to the second driving units. The RPM of the first driving units is half the RPM of the second driving units, and the first and second driving units of each drive rotate in opposite directions. Elastic cushions are interposed between the holder and each second driving unit.Type: GrantFiled: October 27, 1981Date of Patent: April 24, 1984Assignee: Hauni-Werke Korber & Co. KG.Inventor: Peter Schumacher

Patent number: 4361056Abstract: A housing supports a hollow shaft for both axial and rotary movement and also supports a drive input rotor for rotation on an axis perpendicular to the axis of the hollow shaft. The rotor carries an eccentrically located planetary gear which engages a surrounding stationary ring gear, and the planetary gear carries an eccentric crank shaft. A crank arm connects the crank shaft to a rotary coupling mounted on the hollow shaft, and an intermediate portion of the crank arm carries a rack which engages gear teeth on the hollow shaft. The rotor is provided with means for counter-balancing the moving components to provide for high speed winding of wire coils within a motor stator.Type: GrantFiled: April 23, 1980Date of Patent: November 30, 1982Assignee: Mechaneer, Inc.Inventor: Robert D.

Patent number: 4270395Abstract: The motion translation mechanism of the invention includes a crankshaft having a crank arm with an integral eccentric pin. A circular linkpiece is provided which has an opening positioned eccentric to the center axis of the circular linkpiece and positioned within the circular linkpiece eccentric opening. A displacement member with flat bearing surfaces is mounted for reciprocating motion and has a circular opening. A first thrust converting means secured to the circular linkpiece, as well as, second and third thrust converting means that come into consecutive contact with the first thrust converting means. The circular linkpiece is positioned within the circular opening of the displacement member, whereby reciprocating motion transmitted to the displacement member is converted to rotary motion of the crankshaft via the apparatus just enumerated.Type: GrantFiled: June 13, 1979Date of Patent: June 2, 1981Inventor: Reed H. Grundy

Patent number: 4269076Abstract: A motion generating mechanism with a rotary output which comprises a support frame mounting a prime mover coupled through a gear reducer to drive a primary rotary member about a fixed first axis on which a sun gear is concentrically disposed. The primary rotary member carries one or more roller gears that are engaged by the sun gear such that the roller gears rotate about a second axis which is parallel to the fixed first axis and movable with respect to said first axis as the primary rotary gear is driven by the electric motor. Each roller gear has an upper portion on which is mounted a roller adapted to movably engage a slotted section formed in a plate member adapted to be driven by the roller for rotation about the aforementioned fixed first axis such that the motion of a selected point on the plate varies in a combined epicycloidal and harmonic manner relative to the velocity of the primary rotary member.Type: GrantFiled: January 18, 1979Date of Patent: May 26, 1981Assignee: Easom Engineering & Manufacturing, Corp.Inventor: Bart Obra
