Filed: 1933-12-12
Abstract: 410,044. Rolling. MANNESMANNROHREN-WERKE, 1B, Berger Ufer, D³sseldorf, Germany. Dec. 12, 1933, No. 34989. Convention date, Dec. 12, 1932. [Class 83 (iv).] In pilger rolling the spread ing of the billet into the side clearances during one pass, causes an uneven load on the trough of the grooves when the billet is rotated through 90‹ and passes through the next pass, so this is compensated for by shaping the grooves so that the pass is roughly oval at the beginning of the bite and then merges into a circular pass towards the end of the working zone. Fig. 4 shows a section of a roll in which alpha is the reducing zone, # the polishing zone and gamma the exit zone. Fig. 6 shows the cross sections of the grooves in radial planes for values of the angle alpha, so that the lengths of the curves are substantially proportional to the amount of material to be displaced so as to give uniform drawing out pressures at all points on the rolls. For rolls with clearance zones at the troughs of the grooves as well as at the sides as in Specification 369,627, the cross sections of the grooves are made to accommodate the previous spread of the metal into all these clearances when the work is rotated for the next pass. German Specification 523,091 also is referred to.

Title: Improvements in devices for feeding individual razor blades from a pile
IPC: B65B25/00
Filed: 1929-11-21
Abstract: 342,420. Feeding razor blades from stacks or piles. HESSER MASCHINENFABRIK AKT.-GES., F., 99, Olgastrasse, Stuttgart, Germany. Nov. 21, 1929, No. 35589. Convention date, April 8. [Class 117.] Apparatus for feeding razor blades separately from a pile to a wrapping machine comprises a reciprocating slide 6, Figs. 2 and 4, provided with a shallow abutment between its rear and front parts 6a, 6b, which separates the lowest blade and carries it forward on to a support where it is held during the return movement of the slide. From its position on the support, the blade is carried on step by step by a series of pins, 14a .. d, mounted on a rod 13 carried by the reciprocating slide, and is finally transferred to the wrapping machine by a suction transfer device 80. The slide 6 is mounted on a bar 4 which works between guide bars 5 and is actuated by a cam-operated lever 27 and connecting rod. In its forward position, the end 6b of the slide, carrying the blade enters a recess 9a, Fig. 8, of a plate 9 provided with grooves 15, 151 and a slot 7<11> passing through its entire depth. The blade is held on the edges of the recess 9a by a U-shaped holding down member when the slide is returned. The rod 13 carrying the pins 14a .. d is pivotally mounted on the rod 4 and is actuated by a compressed spring 23 so as to maintain a guide roller 16 thereon in contact with a horizontal guide rail 131 during the forward movement of the pins while in engagement with the holes in the blade. Acting in conjunction with the roller a pivoted and spring- controlled switch member 135 functions to pull the rod 13 and the pins down during the backward movement against the action of the spring 23 and allow its return to its upper position in which the pins engage the holes in the blade at the beginning of a feeding stroke. A feeler device comprising a spring-controlled reciprocating pin 70 is employed to control the supply of wrappers from the machine as described in Specification 287,477, [Class 94 (i), Packing &c.], according as to whether its movement is arrested by the presence of a blade on the feed slide or not. Adjustable gates 44, 44<1> at the rear and front of the pile prevent the withdrawal of the blades by the return movement of the feed and the passage of more than one blade in the feed movement. The blades are strung on rods 49, 491 carried by a plate 48 secured in the channel of an overhanging bracket and are forced into contact with the slide, by a sliding member 90. Perferably a weighted rod 58 is adapted to press on the member 90, and is held up by a spring catch 62 during the changing of the piles. The plate 48 is registered by a spring catch 53 engaging a hole therein. The holding channel may be adapted to contain a series of piles which are moved into operative position successively, and in the movement eject the empty magazine.
