Filed: 1918-01-09
Abstract: 122,020. A.B.C. Coupler, Ltd., and Redpath, W. Jan. 9, 1918. Couplings, non-automatic.-In a non-automatic buffer coupling for railway and like vehicles, a coupling-link is engaged by an open rotatable or slidable ring or loop which in one position allows the link to be inserted into the loop and is then moved to a second position where it securely engages the link, a latch being provided if necessary to retain the loop in the second position. In the construction shown in Figs. 1 and 2, the loop C is rotatable in the buffer head A and has an open. ing c of substantially the same width as the opening a in the buffer head for receiving the link B. The link is inserted when the opening c in the loop is uppermost as shown in Fig. 1, and then the loop is rotated to bring the opening c to a lower position, Fig. 2, where it is retained by a latch in the form either of a bent arm D passing through holes c<1>, c<2> in the loop or of a fixed or pivoted plate E on the underside of the buffer head. In a modification, Fig. 5, the loop C' is of somewhat flattened shape and is slidable transversely and horizontally in the buffer head, a latch D being provided to retain the loop in the coupled position. In further modifications, of which one is shown in Fig. 7, the loop G is movable vertically and is retained in the coupling position by its own weight. A latch H is provided to retain the loop in the non-coupling position for fly-shunting. The portion g', Fig. 11, of the loop which is adapted to engage the coupling-link is preferably made of a harder material, such as nickel-chromium steel, than the remaining portion of the loop, the two parts being connected either by riveting or by squeezing the softer metal at g<1> over the ends of the portion g. A spare link B<1> may be carried by the loop C or latch D in the constructions shown in Figs. 1, 2, and 5. The open loop C may also be employed as shown in Fig. 12 in connexion with a Norwegian hook coupling A to permit fly shunting, the continuous side of the loop forming a slidable pivot for the hook J, and the non-continuous portion being adapted either to retain the hook in a permanently raised position or to allow it to fall for coupling purposes.

Title: Improvements in inking devices for typewriters
IPC: B41J27/12
Filed: 1931-01-08
Abstract: 364,843. Typewriters. BERAN, F. and GOLDMANN, F., B÷hlen, near Leipsic, Germany. Jan. 8, 1931, No. 703. [Class 100 (iv).] Roller-inking arrangements.-In a typewriter having an inking-roller located near the printing point and adapted to be struck and moved aside by the types, the inking-roller 11 is mounted in a U-shaped frame 8 adapted to swing about a vertical shaft 7 on a carrier plate 5 attached to a support 1 connected to the shift frame. A ductor roller 16 and an ink reservoir are mounted in a frame formed by a bracket 14 and another plate 6 attached to the support 1. When the inking-roller 11 is struck by the type, it is deflected against the action of a weak spring 9 and makes contact with the ductor roller, and the ink used is of a sticky nature, comprising a glycerine ink with added glue and ammonia, so that the inking-roller is temporarily held by the ink in contact with the ductor roller, until the papercarriage is advanced for letter-spacing. In this movement a rack on a bar pivoted on the paper-carriage rotates a pinion 22 loose on the shaft 15 of the ductor roller 16. The pinion 22 is frictionally coupled to the shaft 15 through a spring 23, and a ratchet-wheel 24 fast on the shaft and engaged by a detent pawl 25. The frame 6, 14 has limited movement against spring action about the shaft 7 so that it can yield to pressure of the rack-bar when paper is being inserted between the platen and the paper-guide rollers located between the platen and the rack-bar. The frame 8 can be deflected bv means of a hand-lever 27 to maintain the inking-roller inoperative for stencil-making ; the inking-device may be enclosed in a casing, in which case the hand-lever 27 projects through a slot in the casing. The ductor-roller gearing may function as a carriage brake for tabulating. The shaft of the inking-roller 11 may be screwthreaded at one end for detachable connection with the frame 8.
