Abstract: A collet for an automatic bar feed machine tool having an outer sleeve 20 and an inner sleeve 21 reciprocable in the outer sleeve, a spring 26 to bias the inner sleeve 21 away from the gripping region 28 of the outer sleeve. Bar stock 33 is gripped in the collet by the outer sleeve end 22 acting on the end 29 of the inner sleeve, the bar being fed through the collet and short ends 36 falling away from the collet during feeding so that bar can be continuously fed through the collet without having to stop the machine to remove short ends.

Abstract: A hydraulically operated bar stock feeder having a hydraulic circuit in which a hydraulic pump drives a hydraulic motor which in turn operates the bar feeder carriage. The hydraulic pump operates a hydraulic cylinder with a designed live center cup attached to the end of the cylinder rod. The hydraulic circuit has a control valve with hydraulic detent which will lock in a forward or backward position. While the control valve is locked in forward position, fluid is allowed to go to a relief valve at the hydraulic motor on the carriage. The relief valve reduces the pressure going to hydraulic motor and deceleration valve. When the carriage reaches the end of track the deceleration valve is depressed, which, through another relief valve at a lower pressure starts the cylinder rod moving outward. Both the cylinder and carriage motor are able to set (not move) under pressure and will start automatically when the lathe chuck is open.

Abstract: In an apparatus for automatically feeding bar stock material into a numerically-controlled automatic lathe, a bar is rotatably clamped and borne by the clamp jaws of several bearing clamps disposed in a row at intervals along the bar and orientated at respectively different angles about the bar, each clamp jaw comprising three pulleys in triangular formation and an endless belt supported on these pulleys, one of which is driven, the bar being clamped between a span of the belt between two pulleys of one jaw and that of the other jaw of each bearing clamp. The bar is thus held at clamping positions that vary helically about the bar as it is fed by a feed pipe into the lathe.

Abstract: A feeding system for barstock on turning machines with a support extending in the feeding direction and with a plurality of holders for holding and slidably guiding a material bar. The holders are slidably guided in the feeding direction on the support and are interconnected by coupling means provided by intersecting links which are pivoted relative to each other and to the holders such that the latter are maintained parallel to each other and can be pushed together and moved apart in the longitudinal direction of the material bar.

Abstract: Bar stock is fed to the chuck of a machine tool by a ball chain having a rigid pusher at the end engagable with the bar stock, the ball chain being advanced by a wheel having pockets for the ball chain.

Abstract: A bar stock feed arrangement for an automatic machine tool, in which a pusher rod, movable along the axis of a feed tube to advance the bar stock, is supported by an annular collar. While the pusher rod remains within the feed tube the collar is locked to the rod by means of a ball and socket arrangement. To permit the pusher rod to emerge from the feed tube the locking action is removed, the collar still assuming a supportive role at the end of the feed tube. Additional supportive means, in the form of split bushings, and a sound damping arrangement are also described.

Abstract: An apparatus is provided for installing sleeves onto elongated substrates such as electrical wiring or cable, where the sleeves are slideably arranged on fingers extending from a carrier belt. The apparatus includes a base having a belt path for receiving the carrier belt and a finger guideway for receiving a finger of the carrier belt. Stripping means are slideably mounted on the base for forcing a sleeve from a finger onto a substrate. An indexing element is provided for moving the carrier belt to a position so that a finger having a sleeve arranged thereon is in the finger guideway each time after a sleeve is stripped from a finger. In use of the device, the sleeve can be stripped from a finger into the die in two stages, where an elongate substrate is inserted into the removed portion of the sleeve between the two stages. For installing non-cylindrical sleeves on cylindrical substrates, a die is mounted to the base at a position to receive the sleeve as it is stripped from a finger.

Abstract: Apparatus is provided for simultaneously rotating and axially feeding an elongated workpiece past an induction heating inductor. The apparatus includes a collet having a passageway therethrough defined in part by radially displaceable fingers normally providing an opening of a diameter smaller than the smallest diameter of the workpiece. A workpiece is pushed through the collet and the collet is simultaneously rotated for the fingers to rotate the workpiece as the latter slides axially along the fingers.

Abstract: An automatic transfer apparatus for transferring articles stacked on a platform, one by one, to a table comprising a gripping head, a gripping finger mounted for vertical movement relative to a support on the gripping head, a drive for moving the support together with the gripper finger backwards and forwards over the platform and the table, second drive for moving the gripper finger into and out of engagement with the article on top of the stack and an adhesive member on the gripping finger for engaging and holding the article.
