摘要:
A carrier for a strand supply bobbin used on strand fabricating machines. The carrier has a raisable and generally circular cap (32) housing a sleeve (37), a disc (38), a ring (39), a compression spring (40), a leaf spring (41), an actuator rod (42), a collar nut (43), a retainer cup (44), a planar reaction surface (45), an actuator plug (46) and freely movable force transmitting elements (47), as operative elements for bobbin control during letoff of strand material. Radial movement of the force transmitting elements (47), to brake or clutch the supply bobbin is determined by (i) the position of the bobbin control actuator rod (42), (ii) the position of the bobbin control actuator rod (46), and (iii) the position of the bobbin control disc (38) within the raisable cap (32) on the carrier.
摘要:
Apparatus for the control of relative strand movement, without significantly affecting or altering strand tension, on a braiding machine with two sets of carriers for a strand supply bobbin being rotated in opposite directions and being generally axially aligned, as a set of front and rear strand carriers and supply bobbins. A set of rear strands pass through peripheral and radially arcuate slots in a carrier mounting table and are guided prior to movement into the slot by a set of cam actuated swing arms movable in a common plane perpendicular to the machine axis. The rear strands move through an arc segment relative to the machine axis for interweaving with a set of front strands. The interwoven rear and front strands are led to a circular ring at the front of the machine having an effective diameter coincident with the rotational axis of the front bobbins. The interwoven strands are then pulled from the machine to a "work center" for tight braiding around a core or mandrel.

Apparatus for rotating a set of braiding machine front strand carriers around the front side of a first table carrying a set of contra-rotating rear strand carriers on the rear side. Strands from the rear carriers pass through arcuate slots in the first table. A second table is in front of the first table. The tables rotate in opposite directions. The apparatus of the invention has a shuttle for mounting each front carrier, with an arcuate slide tang having a length less than the distance between any two first table slots and carrying a radially inner drive block with two actuator slots. A circular shuttle mounting track carried on the first table front side has inner and outer roller segments between any two first table slots engaging the shuttle slide tangs. A circular actuator cam track carried on the first table has a set of inwardly directed V's with an apex inwardly of an inner end of each table slot. A set of shuttle drive assemblies is mounted on the rear side of the second table. Each drive assembly has two symmetrical and articulated drive arms extending laterally from a single actuator post. Each drive arm follows the cam track and carries an actuator dog for articulated movement into and out of driving engagement with a shuttle drive block actuator slot; so that rear carrier strands positioned at the inner end of each table slot pass between front strand carriers and drive assemblies.
摘要:
A filler head for delivering a preselected volume of product to a container, the head having a charging cylinder and a piston movable in the cylinder to define a product chamber therein. Product is delivered under pressure through a passage to the chamber, the piston being movable under product pressure in a direction enlarging the chamber. Adjustable stop means limit chamber enlarging movement of the piston to determine the preselected volume. A plug entering the passage as the piston approaches the end of its discharge stroke restricts the discharge of product to reduce turbulence. A piston valve is movable between the product passage and an outlet passage, in one position interrupting the delivery of product to the chamber for discharge of product from the chamber through the valve to the outlet, and in another position closing the outlet and permitting delivery of product under pressure to the chamber. The piston valve is removable as a unit from the head, for ease of cleaning.

The disclosure relates to a housing in which any one of a plurality of steam trap valve assemblies may be installed and which may be machined to accommodate a plurality of different inlet and outlet conduit configurations. The housing includes a main body through which a central cylindrical passage extends. Flanges extend radially outward from the main body at opposite ends of this passage and serve to connect the main body with the top and bottom members. The main body also includes a pair of additional passages which are parallel to the central cylindrical passage and a pair of bosses which extend radially outward. The top and bottom are made from identical castings and each comprises a circular portion adapted to mate with a flange on the main body and a boss extending diametrically from the perimeter of the flanges across at least past its center. The bosses on both the main body and the top and bottom may be machined to provide a plurality of different fluid flow paths and inlet and outlet connections. The bosses are drilled according to the particular valve assembly installed in the housing and the desired orientation of inlet and outlet connections. By using the disclosed valve housing for a number of different valve assemblies and inlet and outlet conduit configurations, the number of castings required and therefore production costs can be greatly reduced.

A gripper assembly includes a movable clamp member which is rotatable relative to a stationary clamp member from a fully open position to any one of a plurality of closed positions to grip an article of a selected size between clamp members. When a releasable clutch or retainer assembly is in an engaged condition, the clutch prevents rotation of the movable clamp member from any one of the closed positions back to the fully open position. An actuator assembly is operable to release the clutch to enable the movable clamp member to rotate back to the fully open position. The clutch includes a coil spring having a plurality of turns which grip surfaces connected with the stationary and movable clamp members when the clutch is in the engaged condition. The actuator assembly operates the clutch from the engaged condition to the release condition by applying a force to the turns of the coil spring urging the turns to flex in a direction tending to increase the diameter of the coil spring.

摘要:
A speed/torque enhancing power transmission is disclosed that translates slow rotating, high torque motion to high rotation, low torque motion or alternatively high rotating low torque motion to low rotating high torque motion and is suitable as a speed increaser for use in a device like a wind turbine. As a speed increaser the transmission has certain advantages, such as reduced weight and/or size compared to other units having the same performance characteristics. The speed increaser employs a pair of externally toothed spur gears orbiting in a non-rotating manner 180° out of phase inside an internally toothed ring gear. The input drives the ring gear and the orbiting spur gears drive separate eccentrics on the output shaft extending in opposite directions to provide dual output. In one embodiment, cross guide projections on the spur gear and cross guide projections on the housing engage slots in a swash plate.
