Abstract: An automatic board transfer apparatus transfers, positions and delivers boards and comprises an arm which is reciprocable along guides for horizontally guiding the boards and which is vertically movable perpendicularly to the plane of the boards. A pusher and a pin are installed on the arm. The board is transferred in advance along the guides by the pusher and on the way a pin is inserted into the reference hole of the board to thereby transfer the board. Thus, variations in the position of the reference hole of the board caused by reversing the board and variations in board length are accommodated without adjustment, thus making continuous production possible.

Abstract: A belt conveyor has a luffing boom (5) and a supporting leg (10) turningly joined with a free end of the boom. The single conveyor belt (15) of the belt conveyor is guided between the boom (5) and the supporting leg (10) by way of a bend unit (24), that has a so-called curved rolling guide (41). This rolling guide (41) is made up of a rigid part-circular guide (42) joined with the boom (5) and a chain-like curved part (43) dependent from the guide (42), the curved part (43) changing into a curved form on upward luffing of the boom (5) because of the wedge-like form of its chain links (43) or because of a curved rail (55) fixed to the top end of the supporting leg (10), whereas on downward luffing of the boom (5) it takes on a straight, freely hanging form so that it is taken up in the supporting leg (10) and for this reason takes up only a little space between the two runs (28 and 29) of the conveyor belt (15).

A first tube (16) is fixed in the apparatus frame and has a connection (46) for a flexible pipe by which it is connected to a melt chamber. A guide tube (36) has a sliding fit with and can slide in the tube (16), the guide tube being secured to a lead-in tube (32) which is clamped inside a support tube (18), the support tube (18) being arranged to slide on the outside of the first tube (16). Rod adhesive is supplied through the lead-in tube (34), into the guide tube (36) and then to the first tube (16). The guide tube is thin-walled so that effectively the rod has a sliding fit with the internal bore of each of the three tubes referred to. For feeding the rod, a jaw (38) projects through slots in the support tube (18) and lead-in tube (32) and is mounted for movement with the various tubes (18, 32, 36).

Abstract: A walking beam conveyor of the type having a plurality of reciprocally movable notched beams interposed between a plurality of fixed notched beams, cools and transfers elongated articles such as cylindrical bar stock between a furnace and a discharge station. Vertical and horizontal reciprocal motions are applied simultaneously to the movable beams by eccentrics which are mounted on a single drive shaft for advancing the bars along the fixed beams toward the discharge end of the cooling bed. The vertical motion eccentric is operatively connected to the movable beam through a bellcrank lever and the horizontal motion eccentric is connected by a generally horizontal push-pull connection. The beam notches are V-shaped with one sloped surface having a greater length and smaller angle of slope than the other sloped surface. Rotation of the drive shaft in one direction will reciprocate the movable beams causing the bars to rotate 90.degree.

Abstract: A drive chain (38) disclosed is utilized with glass sheet processing equipment (10) to provide frictional driving of conveyor rolls (22) upon rolling movement of the drive chain over an associated support surface (30). Drive chain (38) includes antifriction rollers (40) supported for rolling movement on the support surface (30) and also includes interconnected links (42,44) supported by the antifriction rollers (40) for movement over the support surface in a spaced relationship and having upper surfaces (46) that support and frictionally drive the rolls. Connecting pins (48) interconnect the links and have opposite ends (50) respectively supported by an associated pair of the antifriction rollers (40). Chain links (42,44) are preferably arranged in a side-side relationship in alternating inboard and outboard pairs between the associated pair of antifriction rollers (40). The antifriction drive chain construction reduces friction to eliminate "stick-slip" motion and to also reduce power requirements.

Abstract: Rolled stock running out of a rolling mill is parted into lengths suitable for the cooling bed. Rolled stock cross sections of various sizes are retarded both at approach speeds of more than approximately 20 m/sec and slower, alongside the cooling bed in an approach roller feed bed and then transversely conveyed over the cooling bed. In order to avoid requiring an uneconomically long cooling bed as a result of the sequence times of the lengths of rolled stock, three or more longitudinal braking sections are arranged side by side to enable thin lengths at a high approach speed to be retarded in rapid succession and conveyed across to the cooling bed. Covering means of the braking sections are constructed to provide additional retardation of the lengths, e.g. by blowing air, by lowering brake shoes or by the action of linear electromagnetic motors.
