Abstract: There is disclosed herein a pulling apparatus comprising a pair of spaced vertical members each of which is supported upon a base member by a pair of depending diverging support members of unequal length which operate to rigidly support the vertical members against the forces exerted thereon during the pulling operation. An additional vertically extending support member also extends from one of the depending support members to further increase the rigidity thereof. The vertical members may each be provided with opposed channels within which a pulley is movably disposed, said pulley being adjustably supported by a chain or the like engaging a load holding assembly provided upon the upper portion of the vertical members.

Abstract: A method of manufacturing a high fin density heat dissipator is disclosed in which the dissipator is extruded through a die in a partially cylindrical shape with the elongated fins arranged on the base and extending radially therefrom. The extruded dissipator is straightened under tensile and bumping forces in a manner such that the base assumes a planar shape and the fins become substantially parallel to each other. Apparatus for straightening the extruded dissipator and a die for extruding the same are illustrated and described.

Abstract: An improved method of making vehicle wheel rims particularly suitable for use with materials having relatively low ductility, such as aluminum, is disclosed. A circumferential drop center well is formed about the periphery of the band and work hardened so that the well material exhibits higher strength and lower ductility than the remaining band material. The strength and ductility differential between the well and band material adjacent thereto assists in confining material movement in subsequent rim forming operations and induces drawing of the rim bead seat area material.

The apparatus includes means for laterally clamping the axle assembly and means for applying a bending force to the axle at a position laterally displaced from that of the clamping means. A base assembly is utilized to support the axle at its normal height after the wheel has been removed. A novel breast plate is utilized to support the base of a horizontally disposed hydraulic jack which provides the desired camber correction. Preferred embodiments are particularly designed to be utilized with Volkswagen automobiles.

Abstract: An annular groove (35) is located in an outer surface of an inner toroid (31), and is partly covered by an inner surface of an outer toroid (32). Alternatively, an annular groove (25) is located in an inner surface of an outer toroid (22), and is partly covered by an outer surface of an inner toroid (21). As the toroids are rotated together about different, intersecting axes, an elongated workpiece (W) is introduced into an open portion of the annular groove, advances into the closed portion of the annular groove, and is extruded through a die (48) upon again approaching the open portion of the annular groove, thereby forming an elongated product (P).

Abstract: Material to be manually fed into a machine's point of operation is supported by a surface plate. A pusher, interrelated with the surface plate by keying means, is held by the machine operator such that the operator uses the pusher to push the material into the machine point of operation without having the operator's hands coming in dangerous proximity with the machine point of operation or with the machine's structure.

Abstract: There is disclosed herein a safety tie down assembly particularly adapted for use with pulling apparatus of the type employed in the repair of collision damage to motor vehicles. The safety tie down assembly comprises a pair of attachment members fixedly secured to outwardly facing surfaces of the spaced vertically extending members of the pulling apparatus. Chains or the like are attached to each of the attachment members and are designed to be secured to anchors when the pulling apparatus is being operated so as to restrain or limit movement of the pulling apparatus should the primary anchoring assembly break or otherwise let loose.

Abstract: An apparatus for manufacturing heat transfer tubes for use in evaporators and coolers for freezers, air conditioning units, refrigerators, and the like, with close machining tolerances. It forms cavities, with small openings communicating them with the outside, on the inside of a tube, through three steps of forming a multiplicity of alternate grooves and ribs in parallel on the inner surface of the tube, forming cuts in the concentrically directed crests of the ribs, and then forcing the crests sidewise so that the crest of each rib is bent down onto an intermediate part of the adjacent rib to form a cavity in between.

Abstract: A method and apparatus for reforming and straightening damaged bodies of vehicles whereby corrective forces are applied to the vehicle through one or more elongated force transmitting elements. A measuring bridge is coupled to the vehicle by means of a plurality of vertical elements. The vertical elements attached to datum points on undamaged portions of the vehicle are restrained from movement relative to the measuring bridge to properly orient it to the vehicle. In addition, vertical elements attached to datum points in damaged portions of a vehicle are supported on the bridge for movement in two perpendicular directions and a plane parallel to the vehicle and are extensible along their length to permit the vertical elements to follow the reforming of the vehicle during the application of force. The measuring bridge is supported by a plurality of air pressure cylinders to maintain proper orientation of the bridge with respect to the vehicle.

Abstract: A high speed press for coining workpieces includes a head actuable by high pressure fluid. The high speed press also includes an advancing assembly for advancing individual workpieces to a position adjacent the head to be coined. The advancing assembly includes a reciprocating apparatus for advancing the individual workpieces to a position to be coined by the head. The advancing assembly is in fluid communication with the pressurized fluid employed to operate the head such that the operation of the advancing mechanism is synchronized with the operation of the head.

Abstract: A method of quickly restoring a deformed outer vehicle panel to its original contour which consists in the steps of placing a deflated inflateable air bag between the inner surface of the indented panel and against an unyielding member in the vehicle, then inflating the air bag with sufficient air pressure to force the indented panel portion back to normal contour, and, if necessary, hammering out any irregularities in the panel while the air bag still remains inflated. After the panel has been restored to normal contour, the air bag is deflated and removed.
