Abstract: 166,960. Payne, S., Payne &. Sons (Otley), Ltd., Stott, E., and Dawson & Sons (Otley), Ltd., W. April 23, 1920. Pile tables and supports for sheet-feeds; separators; carriers; guides.-Sheets are separated and fed from a pile by means of a suction or like separator which bends the edge of the top sheet and raises it to allow a flexible tray or platform carried by bars on a pair of endless chains to pass between the top sheet and the pile, the sheet being deposited on the tray when the suction is cut off. As shown in Fig. 1, the trays are formed of steel or other flexible tapes 28 attached to bars 27 carried by chains 26, which pass over sprocketwheels 24. The top sheet of a pile is acted on by a set of suction nozzles 3 on a shaft 2 carried by arms 4 fitted with studs 6 mounted in levers 5, which are formed with rollers 9 acted on by cams 10 to depress the suction nozzles on to the pile and lift them with the top sheet adhering to permit a tray 28 to move under the top sheet. The shaft 2 is rotated to bend up the edge of the sheet by means of a connecting-rod 12 and a lever 13 with a roller 15 acted on by a cam 16 on the shaft 11. A gripper 17 may coact with the nozzles 3 to lift the top sheet, this gripper being acted on by a cam 23 on the shaft 11. As shown, the separated sheet is carried by the tray 28 until it reaches stops 29 which stop the sheet so that it falls through an open space between the crossbars 27 on to a feed-tables 30. Instead of lifting the separator from the pile, the pile-table may be dropped after the sheet is held by the separator. The chains 26 are driven by a continuous or intermittent drive. In a modification the chains 26 are caused to travel downwards and around the pile, the separated sheet passing from the trays 28 into guides which direct it into forwarding rollers, or on to forwarding bands or tapes.

Title: An Improved Direction Indicator and Mechanical Telegraph for Air, Sea or Land Purposes.
Inventor: STURDY PHILIP
IPC: G05G7/10
Filed: 1918-07-12
Abstract: 129,448. Sturdy, P. July 12, 1918. Mechanical telegraphs.-A mechanical telegraph having identical transmitting and receiving instruments, is arranged so that the same pointer may be used to give indications on two or more independent dials in different planes, or so that the pointer may be moved out of proximity to the indicating-dial and used to indicate any direction in space. The apparatus is particularly adapted for use in aircraft, submarines, or for directing artillery. The pointer F', Figs. 1 and 2, is manipulated by a thumb-piece F<2> and can be rotated over a fixed dial A<1>. The pointer is mounted in the forked end of a shaft D rotatable in bearings C carried by parallel-motion links B<1>. Rotation of one pointer on its pivot is communicated to the other pointer by an endless chain &c. passing over pulleys FE on the pointer spindles. Rotation of the shaft D and the pointers &c. carried thereby, combined with the rotation about the axes of the pointer spindles which are at right-angles to the axis of the shaft, allows the pointers to be moved simultaneously to any direction in space. The parallel-motion link mounting allows the shaft and pointers to be raised clear of the dials as indicated in broken lines. The shaft is held in its raised or lowered position by springs G. When clear of the dials A<1>, the pointers may be used to point to indications on one or more additional dials (not shown). The dials may be plane or curved, and not necessarily circular. When direct transmission by straight shaft D is not permissible, the apparatus may be modified as shown in Fig. 4 for chain or cord transmission, the chains &c. being led over suitably placed guide-pulleys. The pointer C' and dial A' are carried by a sleeve B rotatable about its axis, this rotation being transmitted by a chain &c. F passing over sprockets or pulleys BF. The indication on the moving dial is given by a fixed pointer A<4>. The pointer C' is mounted for rotation about an axis at right-angles to that of the sleeve and carries a pinion gearing with a cvlindrical rack E which is raised or lowered by rotation of the pointer, but not affected by rotation of the sleeve B. Movement of the rack rotates a second pinion D<2> engaging therewith. Rotation of one pinion D<2> is transmitted to the other pinion by a. chain &c. H, causing a corresponding movement of the other rack and pointer geared therewith. The support of the pinion D' is adjustably secured to the support A of the fixed pointer A<4>. When the dial A' is in use for transmitting indications, the pointer C' is turned vertically downwards as shown in broken lines to indicate that it is not in use. The apparatus may also be modified for hydraulic, flexible-shaft, or other form of transmission.

The brackets 2, Fig. 1, are each made in two parts bolted together and fastened to the hollow shaft 1 by screws 5. The tines 6 are inserted in slots in lugs 7<1> and mounted on pivot bolts 8, extensions of the tines being connected to the brackets bv safety bolts 10. When a bolt 10 is sheared the corresponding tine 6 comes into contact with a shoulder 14 and the pivot bolt 8 may also be sheared. The tine is prevented from flying off by a rope or wire 12 passed through holes in the tine and bracket. The points 15 of the tines are conical and the cutting-parts 15<1> are adapted to throw the excavated clods to either side, being wedge-shaped in section with the angle of the wedge becoming progressively more obtuse on either side of the section 3-3. In a modification, the engaging surfaces of the shaft and brackets 16, Fig. 4, are grooved to prevent rotation, and the inner ends of the tines 19 are concentric with the brackets, leaf springs 24 being inserted between them to cause vibration of the tines when the bolts 21 are sheared. The faces of the cutting-part 28 of the tines are concave and act as shovels. The path of the end of the cutting-edge is approximately cycloidal and the curvature increases towards the root of the tine.
