Abstract: A carrier bracket for use with a power cylinder of the type having an elongated cylinder member and a reciprocally movable piston therein for transferring reciprocal movement of the piston to a desired workpiece. The carrer bracket includes a central bracket portion, a pair of guide arms extending outwardly from the central bracket portion in which each of the guide arms is provided with elongated surface, a mechanism to permit limited flexing movement of the arms relative to the central bracket so as to facilitate the limited selective movement of the arms toward and away from one another and a device for causing the limited selective movement of the arms toward and away from one another.

Abstract: A rotary actuator having a housing defining an opening, an output shaft extending through the opening, a stator vane and rotor vane associated with the output shaft and opening to define a plurality of actuation chambers and an inner surface of the housing extending inwardly past a shoulder portion of the output shaft to seal directly against the shaft.

Abstract: A pneumatic cylinder having an elongatged cylinder member, a reciprocally movable piston, an elongated slot formed in the cylinder member, a seal for sealing the slot during reciprocal movement of the piston and a transfer means for transferring reciprocal movement of the piston to a workpiece. The above pneumatic cylinder includes a mechanisn for providing pneumatic fluid pressure to a secondary pneumatic unit connected to, and movable with, the piston including a manifold connected with the transfer means and conduit members extending from the pneumatic chambers in the cylinder member for directing pneumatic pressure from such chambers to the transfer means.

Abstract: A pneumatic cylinder having an elongated cylinder member, a reciprocally movable piston, transfer means for transferring reciprocal movement of the piston to a work piece and a brake mechanism associated and movable with the transfer means for creating a braking force between the transfer means and a portion of the cylinder member. The brake mechanism includes a first brake surface connected with the transfer means, a second brake surface formed by an exterior surface portion of the cylinder member and a brake actuation mechanism for selectively causing movement of the first and second brake surfaces into braking engagement with one another.

Abstract: A carrier bracket for use with a power cylinder of the type having an elongated cylinder member and a reciprocally movable piston therein for transferring reciprocal movement of the piston to a desired work piece. The carrier bracket includes a central bracket portion, a pair of guide arms extending outwardly from the central bracket portion, an elongated bearing rod secured in a fixed position relative to each of the inner surfaces of the guide arms, a mechanism to permit limited flexing movement of the arms relative to the central bracket so as to facilitate the limited selective movement of the arms toward and away from one another and a device for causing the limited selected movement of the arms toward and away from one another.

Abstract: A fluid pressure cylinder of the rodless type having a reciprocally movable piston, an elongated slot within the cylinder and an improved sealing element for successively sealing the elongated slot during movement of the piston. The improved sealing element is constructed of a generally flexible material and includes a sealing portion for creating a seal against the inner side wall of the cylinder adjacent to the elongated slot and a portion which is adapted for at least partial insertion wthin the slot so as to retain the seal member within the slot during an absence of pressure within the cylinder.

Abstract: A fluid power cylinder having a cylinder with an elongated slot extending generally parallel to the longitudinal axis of the cylinder, a reciprocally movable piston and a strip sealing means for successively sealing the slot during movement of the piston. The sealing member is of a laminated construction and is constructed partially of a magnetized rubber-like material for magnetic attraction to the cylinder wall adjacent the slot. The sealing member also includes beveled edges for engagement with beveled edges adjacent the slot.

Abstract: A seal assembly for use in a cable cylinder to form an effective seal about a generally cylindrical cable section. The seal assembly includes primary and secondary seal members disposed on opposite sides of an alignment sleeve and a retainer sleeve, all of which are disposed within the central bore of a gland member. The central bore includes a plurality of cylindrical bore portions and means cooperating with the retainer sleeve for retaining the seal members and alignment sleeve within the gland for easy insertion and removal thereof.

Abstract: A seal assembly for use in a cable cylinder to form an effective seal about a generally cylindrical cable section. The seal assembly includes first and second seal retaining member disposed on opposite sides of a seal element, all of which are disposed within a cylindrical bore of a gland member. The cylindrical bore includes a shoulder portion to retain one of the retaining members and a groove to retain the other for easy insertion and removal thereof.

Abstract: A combination wheel brake assembly for connection with a wheel or other rotatable element comprising a rotatable axle, a spring applied, hydraulically released brake assembly, a wheel hub rotatably supported on the axle and adapted for connection with the wheel and free wheeling hub mechanism for selectively rendering the wheel hub free wheeling to permit the wheel to be freely rotated despite a loss or failure of hydraulic pressure and despite braking engagement of the braking elements.
