Abstract: The drive cylinder component of a hydraulic press is reciprocable relative to a fixed ram to drive the press slide toward the press bed for the performance of work on a workpiece between the slide and bed. The cylinder component is provided with an integral radially outwardly extending flange about the periphery thereof at the open end of the cylinder, and the press frame is provided with a stop plate surrounding the cylinder and disposed in the path of the flange so as to be engaged thereby as the cylinder approaches its lowermost position with respect to the press bed. The stop plate and flange are adapted to take a full press tonnage load. The flange also supports guide components engaging gibbing on the press frame for guidance and support of the cylinder and thus the slide during reciprocation thereof.

Abstract: The present invention relates to a mechanical press, and in particular to a guiding arrangement for the reciprocating slide of such a press. The press comprises a crown and bed and a plurality of vertical uprights connecting the crown and bed. A plurality of guideposts are rigidly connected to the crown and depend downwardly therefrom, the guideposts being parallel to each other and substantially perpendicular to the plane of the bed. The guideposts each have free ends which are unsupported and terminate short of the bed of the press so that the parallelism of the guidepins is determined solely by their connection to the crown. In order to counteract the non-vertical forces exerted on the slide by the connection arms, which tend to cause the slide to tilt about a horizontal axis perpendicular to the axis of the crankshaft, bearings are mounted between the connection assembly and the crown.

Abstract: The invention relates to a mechanical press and in particular to a means for achieving thermal stability, particularly shutheight stability, by utilizing the waste heat from lubricant circulated through the drive assembly to heat the uprights. The oil is circulated through the crankshaft and connection arm assembly in the crown and then caused to flow through a thermal transfer device mounted to each of the uprights wherein the heated oil transfers a portion of its heat to the uprights so that they elongate due to thermal expansion at the same rate as the connection arms. The thermal transfer devices comprise a plurality of baffles over and through which the oil flows under gravity or pressure, wherein the baffles cause the oil to form a plurality of vertically spaced pools in good thermal contact with the uprights.

Abstract: An injection mold with locking device comprises a fixed backing plate and a fixed mold part plate which are connected to each other by four tie rods. A movable mold part plate is connected to the fixed backing plate through a drive and locking mechanism which is capable of moving the movable mold part plate into a mold position with the fixed mold part plate. A thermal force control apparatus is associated with one or more of the tie rods for changing the temperature of the tie rods and thereby causing the tie rods either to expand or contract. By such expansion or contraction, the exact force applied between the fixed and movable mold part plates can be adjusted to a desired level.

The tension elements have their ends connected to stressing units alternately on one side and the other of the press and lying in chambers formed in the posts. The units interconnect ends of the outer tension elements in each chamber.

Abstract: A press has at least one reciprocal ram securing a die movable to and from an opposing die, the ram normally spacing the dies apart with a predetermined normal clearance. The die is retained in the ram assembly with at least one tensioned longitudinal bolt which bolt also normally compresses a spacer member, the bolt having longitudinal stretching means selectively actionable for longitudinally stretching the bolt without otherwise affecting bolt adjustment to relieve compression on the spacer member and permit selective transverse removal of the spacer member. When greater than normal die access clearance is required, the bolt is stretched, the spacer member removed and the ram longitudinally shortened in length for the increased clearance. Ram relengthening, spacer member replacement and an ultimate relieving of bolt stretching reassembles the ram in exact original normal form with the exact same bolt tensioning.

The entire drive (less motor) and rams are carried from the press head and these components are movable away from the bed when the tools between the ram and bed encounter an obstruction beyond the preload. The preload limits maximum operative force that will be transmitted in the mechanisms where precise control of the components/dimensions may be difficult to maintain because of manufacturing limitations or because of thermal expansion.

Abstract: A trash compactor using a dolly as a receptacle for the trash to be compacted. The dolly is normally spring supported ready for movement into and out of the compactor, but when in the compactor and subjected to compacting pressure, the dolly is pressed downwardly, upon the beams of the main compactor frame which then takes the full compacting pressures.A novel construction of the dolly and compactor floor of the main frame makes such transfer of load possible. The compacting pressure is developed by four hydraulic cylinders, all of which are mounted on a common plate. The rod ends of the two center cylinders are connected to the top member of the main frame and the cylinder ends are connected to the common plate. The rod ends of the remaining two cylinders are connected to the main compacting plate with the cylinder ends mounted on the common plate. With the four cylinders mounted in this manner, twice the movement of the compacting ram is obtained.

Abstract: An improved baling machine for compacting loose waste material, such as paper, cardboard and the like. A pair of hydraulic cylinders, oriented crosswise to one another, when energized, cause a platen to move downward within a cabinet structure to compress the waste material contained therein. Because of the manner in which the hydraulic cylinders are pivotally mounted with respect to the cabinet frame and the movable platen, the force applied to the material to be baled increases as the stroke of the cylinder piston increases. Also, a unique arrangement of platen guide bars, cooperating with guide slots in the cabinet frame, prevent the platen from tipping and binding during the traversal of the platen.

These liners and wear strips can be replaced without disassembling the press by withdrawing the bolster from the cavity.

Abstract: The cotton module builder comprises a mobile, open-bottomed rectangular frame structure into which field cotton can be deposited. A compacting mechanism is mounted at the open top of the frame structure in order to compress the cotton therein into a compact, self-supporting stack (or module) which can be left in the field when the module builder is moved to a new location. The stack can then be picked up later and transported to a cotton gin.An improved side frame structure for the module builder increases the structural rigidity thereof and includes a continuous side wall beam of triangular cross sectional configuration interconnecting the side wall struts. This beam provides high torsional resistance and minimizes the horizontal deflections at the base of the vehicle, especially when the rear door of the module builder is open as when the stack or module of cotton is being deposited in the field.

Abstract: In a hydraulic press for heavy workpieces the frame of which comprises two yokes spaced by columns, the yokes are movable towards and from each other by the hydraulic working cylinders of the press. At least one of the yokes carries tools displaceable along the yoke. The arrangement makes it possible for the tools to work on every portion of a workpiece filling out the entire space between the columns, yet the cylinders are fixed relatively to the yoke carrying them which eliminates the need for flexible connections for the hydraulic medium.
