Abstract: A metal forming press has an oscillating beam driven at its center by a connecting rod connected to a throw on a crankshaft. The upper end of the beam is pivoted to a link which drives a ram. The lower end of the beam pivots about a rotating eccentric shaft having an eccentric lobe. As the beam oscillates, these eccentricities cause the lower pivot to move toward and away from the ram so that the arc of the upper pivot approximates a straight line.

Abstract: A system for servicing a racing car or other car at a track, other race course, or similar destination employs an open platform for supporting the car by its tires in a horizontal position. The platform supports the car, and is itself supported by a crawler, in a carrier vehicle, for example a truck or trailer, when the carrier vehicle is transporting the car. The crawler and platform are also used to unload and load the car from and into the carrier vehicle. To unload the car at the destination, the crawler, with the platform and car on it, is driven out of the carrier vehicle and onto the ground. Next, the platform is elevated by extending its legs so that it rises off, is spaced from, and straddles the crawler. Then the crawler is driven out from under the platform. Then the platform is lowered to the ground., where it is used as a lift to elevate the car so that its undercarriage may be accessed. The platform may also be used to tune the chassis of the car.

Abstract: A method of die-necking the open end of a can body to form a reduced diameter neck having a smooth profile comprising forming a reduced neck at the open end of the cylindrical sidewall of the can body by engaging the open end of the sidewall with a die having a multi-radius forming profile, with each successive radius from the entrance to the exit of the die being smaller than the previous radius and with the angle through which each successive radius extends being equal to or smaller than the angle of the previous radius. Then at subsequent die-forming stations, forming progressively smaller reduced diameter necks by a series of dies, all of which preferably have the same multi-radiused forming surface profile which virtually eliminates the undesirable formation of pleats in the final neck configuration.

Abstract: The system provides a lubricating fluid between a wall which defines a cavity and a member which passes through the cavity. The system includes a passageway for supplying lubricating fluid to the cavity at a velocity and a fluid outlet for introducing the fluid from the passageway to the cavity such that a centrifugal force, corresponding to the velocity of the fluid supplied from the passageway, acts on the fluid flowing from the fluid outlet to cause the fluid to have a laminar flow over the cavity wall.

Abstract: A lubrication ring, for use in a fabrication press having an assembly with a main cavity and a die nib disposed on a surface of the cavity for ironing a workpiece passing through the cavity, includes a groove surrounding a periphery of and opening into the main cavity of the assembly. At least one passage is provided for introducing a fluid into the groove so as to flow within the groove. The fluid is introduced into the groove at a velocity which causes a centrifugal force exceeding the force of gravity to act on the fluid flowing in the groove.

Abstract: A cupfeeder for feeding cups from a supply chute to a feed location in operative alignment with a drawing and ironing machine is disclosed. The cupfeeding mechanism comprises a push rod mechanism mechanically driven in reciprocating strokes to advance a cup which has dropped from the lower end of the chute to the feed location along a transfer path defined by a positioning member. The push rod mechanism includes an inner push rod extending telescopically from an outer push rod driven by the reciprocating drive. The inner push rod is maintained by pressurized fluid in a fixed axial location, relative to the outer push rod, to project forwardly therefrom to a maximum extent to engage the cups in the cupfeeding process. In response to jamming of a cup within the drawing and ironing station, pressurized fluid is re-routed within the outer push rod to retract the inner push rod and prevent further transfer of cups along the transfer path.

Abstract: A horizontally movable ram and crank drive mechanism therefor for reciprocating the working end of the ram in straight line motion through a die pack for ironing and drawing metallic can bodies is disclosed. The ram is supported by a hydrostatic type bearing support assembly to counteract gravitational vertical deflection of the unsupported working end of the ram. A cardan type crank drive mechanism for converting rotational input force into straight line reciprocating movement of an output shaft is also disclosed.

Abstract: A hydraulic cup holder for use in a draw and iron can making press is disclosed. This cup holder produces increased pressure between the cup being reformed and its holding members, reducing the tendency for wrinkles to occur in reforming the cup into a can body.
