Title: Typing impression control for typewriters
IPC: B41J7/94
Filed: 1961-07-04
Abstract: 991,922. Typewriters. SPERRY RAND CORPORATION. July 4, 1961 [July 11, 1960], No. 24131/61. Heading B6F. Collective adjustment of impact.-The force of impact of all type levers 24 is determined by the length of time a cam 13 is in contact with a continuously rotating power roller 11, and by the effect of a camming roller 16 on a crank lever 17. This is controlled by cranks 15 carrying adjustable screws 65-66 which engage a movable limit strip 44 on a carrier bar 30, mounted for vertical movement on a lever 32 adjustable by a knob cam control 65-68 and linkage 70-72 thereby collectively varying the distance of movement of all the adjustable screws 65-56. Letter - by - letter adjustment.- Individual impact control for each letter is made by adjustment of screws 55, 56 in lugs 54 on base members 53 of the cranks 15. A nylon strip 57 with tight screw holes prevents the screws becoming loose. Which of the screws 55, 56 that engage the strip 44, is determined by the case-shift position. A crank 49, 47 is operated by a case-shift action (see below) and a bail rocker 46 is drawn upwardly from the position in Fig. 1 to that in Fig. 2 (not shown). This pulls the legs 36, 37 if a wire bail and slides the strip 44 from above one row of screws 55 to the other row 56. Case-shift action.-Operation of case shift key 97 operates linkage 96, 94, Fig. 3, and cranks 88, 89 pivot. A pawl 86 is released either by the nose 87 or 91 according to which case - shift position exists and the pawl engages a ratchet 81 keyed to a continuously rotating shaft 80. The pawl thereby rotates an eccentric disc 82 on which it is mounted a half-arevolution to raise or lower an arm 51 connected to the type-basket. It is this arm 51 which operates the crank 47 to alter the impression adjustment mechanism referred to above.

Title: Improvements relating to the handling and delivery of concrete mixtures and other materials
IPC: B28B21/32
Filed: 1930-08-13
Abstract: 361,348. Feeding devices for granular &c. materials. STANTON IRONWORKS CO., Ltd., near Nottingham, and RIDLEY, W., 18, Cromwell Road, Beeston, Nottinghamshire. Aug. 13, 1930, No. 24281. [Class 59.] Apparatus for distributing solid or semi-solid materials comprises a trough or the like, which, when charged with the material, is extended over the area to be supplied and, as it is withdrawn, ejects the material progressively over its end. The trough is constantly co-operating at some part of its length with a hopper or the like and is automatically charged as it is moved towards the extended position. The apparatus is particularly applicable for supplying concrete and similar mixtures to rotary moulds for making or lining pipes centrifugally and in laying roads or road foundations. Apparatus shown diagrammatically in Figs. 1 and 3 comprises a hopper e mounted to move transversely on a carriage c which itself travels on rails b in front of a row of moulds a. The lower end of the hopper is closed by a trough f which can be reciprocated relatively to the hopper so as to extend into any one of the moulds. As it moves to enter the mould the trough is charged with concrete from the hopper but, when it is withdrawn, the material in the trough is prevented by a door, at the back of the hopper and fitting into the trough, from travelling backward with the trough and it is therefore ejected progressively from the end of the trough. The hopper is charged from a concrete grinder d. A plate n extending outwards from the side of the hopper covers the trough in its charged position. Flaps hinged on the ccver and projecting into the trough, so that they can swing away from but not towards the hopper, aid the door at the back of the hopper in causing the ejection of the charge. Fig. 11 shows a cross section of the trough f. The cover n makes a seal with the trough by means of flanges n<2> which slide between spring-pressed faces n<3>, n<4>, provided by channel and angle-irons on the trough. The trough is moved on rollers k by means of a rack gear q, r. Electric motors are provided on the carriage to drive the carriage and to move the hopper and trough as required.
