Title: Improvements in and relating to axle boxes
IPC: B61F15/12
Filed: 1942-01-28
Abstract: 547,390. Axle-boxes; roller bearings. M.E. ENGINEERING, Ltd., and JUDELL, O. Jan. 28, 1942, No. 1212. [Class 12 (i)] An axle-box consists of two pressed sheet-metal half-cylinders 1, 2, Fig. 3, held together by interengaging clips 6 and tongues 7 along the longitudinal edges of the half-cylinders and secured against axial movement by a bracket 4 passing around between the clips. Each member has a nipple 3 for self-alignment whilst straps 13 on the bracket prevent rotary movement of the cylinder. Semicircular washers, Fig. 6, are introduced between the roller cage and the cylinder ends and consist of a felt washer and a steel washer connected by punched teeth 14, the ends of the steel washer being bent round the felt. The roller cage, Fig. 5, consists of flat steel U-shaped members 8 welded together to produce two half-cylinders hinged together at one end and united by pins or journals at the other end, the joint in each case consisting of one member 17 embracing another member 18 which carries a smaller roller 21 held in place by rivets or pins through the members 17, 18. To facilitate assembly, the roller 21 is retained by unequal pins 19, 20 and a spring clip 22. For an outside axle-box, Fig. 8, the lid 23 is secured by a bayonet joint and has a thrust face 27.

Title: Improvements in self loading transports
IPC: E02F3/348
Filed: 1956-01-13
Abstract: 785,413. Earth-working apparatus. AMERICAN ZINC, LEAD & SMELTING CO. Jan. 13, 1956 [Jan. 17, 1955], No. 1248/56. Class 68(1) In a machine for loading and conveying loose material the open rear end of a scoop 11 extends into and has a pivoted connection 13 with a trough 12, the open rear end of which extends into and has a pivotal connection 20 with a material - receiving container 16 mounted on a mobile chassis. In the rear wall 18 of the container 16 is a discharge opening that can be closed by a two part gate. To each end of each of the arcuate overlapping parts 30a, 30b of the gate is secured an arm, the'two arms thus disposed on either side of the container 16 being pivotally mounted about a trunnion 43 on said side of the container. A cable 23 extends from a winch on a tractor for towing said machine about a pulley 24 secured to a cross member 21 of the scoop and passes about a sheave.27 before being secured to the part 30a of the gate. With the part 30a of the gate held in fixed relation to the container 16 and the scoop extending and downwardly of the chassis winding in of the cable 23 causes rotation of the scoop about the pivotal connection 13 until stops on the scoop engage the trough whereupon the scoop and the trough pivot as a single unit about the pivotal connection 20 so that material is discharged from the scoop through the trough into the container. The part 30a of the gate can either be held in fixed relation to the container by locking it to the container when the gate closes the opening, or/when it abuts against a rear stabilizer support 28 the gate then being open. With the cable 23 maintained at a fixed length and on release of the part 30a from the first position and with the scoop in the raised position, the scoop would pivot forward and cause first the part 30a to be withdrawn upwards and rearwards and then the parts 30a, 30b on abutting surfaces on said parts engaging. The parts 30a, 30b are pulled forward to close the opening by forward movement of the trough, the trough and the arms of the part 30a being interconnected by a chain 84 and spring unit 86. Latches 77 mounted on the trough are urged by gravity to engage the spring units 86 to lock the part 30a in the opening and closing positions and are withdrawn by cable-actuated linkage 64, 65, 69, 71, 73, 76.

Title: Improvements in and connected with ships' and other similar telegraphic apparatus
IPC: G08B9/00
Filed: 1930-01-15
Abstract: 347,177. Electric signalling systems. CHADBURN'S (SHIP) TELEGRAPH CO., Ltd. and BAMFORD, A. C., Cyprus Road, Bootle, Lancashire. Jan. 15, 1930, No. 1400. [Class 40 (i).] In electric telegraphic apparatus for use on ships or for similar purposes, the transmitter has two sets of order indications, one for " ahead " orders, the other for " astern " orders, while the receiver has only one set of order indications to be used in conjunction with an "ahead" or an "astern" indication. In the construction shown, the transmitter is provided with a contactor which is adapted to engage a ring 3 connected to a source of current, a pair of contacts 2 adapted to complete the circuits of lamps 8 at the receiver indicating the directions " ahead " and "astern," and spaced contacts 1 corresponding to a " stop '"order indication and two sets of speed indications, one set for " ahead " and one for "astern " directions. The order contacts are connected in pairs by wires 10, and each pair is connected by a wire 0 through lamps 6 to a corresponding order contact 5 on the receiver. The contacts 5 are adapted to be engaged by a circular contactor (not shown) which is formed with a gap and is adapted to form a bridge between the contacts 5 and a contact 14, the latter being connected by a wire 16 to a relay 17 controlling the operation of sound-signalling apparatus 18 at the transmitter and receiver. Movement of the transmitter handle to an order position causes operation of the sound-signalling apparatus and illumination of a pair of lamps 6. One set of lamps 8 is also illuminated except in the case when the "stop" order is given. Operation of the reply mechanism at the receiver brings the gap in the contactor over the contact 5 previously in circuit, so that the circuit is opened and the lamps 6 are extinguished. If it is desired that the lamps 6 should remain alight until a succeeding order is transmitted, the contactor of the receiver is provided with a contact in the gap and with a second contact engaging a ring 5x so that operation of the reply mechanism results only in the cessation of the audible signals. In a modification the receiver, of circular form, is connected to an additional receiver in the form of a large indicator of rectangular shape. Specifications 19100/11, [Class 40 (i), Electric signalling systems &c.], and 347,294 are referred to.

Abstract: 1283470 Haymaker P W ZWEEGERS 12 Jan 1971 [14 Jan 1970] 1491/71 Heading A1F An implement such as a haymaker comprises a movable frame which carries circular tubes 1 which rotate in planes slightly inclined to the horizontal, forwardly and downwardly and which carry resilient tines 3 which protrude almost radially. Means are provided to guide upwardly the outer ends of tines 3 when the tines meet an obstruction such as the ground. As shown in Fig. 2, tine 3 is bent near the coiled end 5 and is mounted at the end of a cranked rod 8 which is rotatably held by lug 11 and can take one of two positions in bracket 12. In the full-line position of Fig. 2 the tine, which is rotating left to right, moves up sloping cam 7 when it meets an obstruction so that its end is lifted. In the broken line case the tine is lifted by tube 1 itself. In the embodiment of Fig. 4, tine 3 is mounted to a pivot pin 13 extending into a bushing 14 connected to tube 1. With the correct orientation of pin 13 the outer end of tine 3 rises on meeting an obstruction. In a further embodiment (Fig. 5) the tines are mounted on pivot 13 at the end of lever 15 which is pivoted between its ends at 17. On meeting an obstruction, end 16 of lever 15 abuts tube 1 and the tines are lifted by tube 1.

Abstract: The destructive hydrogenation of solid carbonaceous materials is carried out in the presence of catalysts comprising preformed zinc salts of carboxylic acids of low molecular weight, i.e. having less than five carbon atoms in the molecule.  Zinc formate, acetate, and zinc salts of propionic and butyric acids are specified in amount of 0,1 to 2 per cent by weight of the coal and are used preferably with an addition of halogen, halogen halide or compounds furnishing the same, e.g. ammonium chloride, halides of metalloids, e.g. methyl chloride, ethyl chloride, methylene chloride, ethylene chloride, propylene chloride or the corresponding chlorides or iodides, fluoroform, carbon tetrachloride, chlorobenzene, iodobenzene, sulphurous chloride, sulphur tetrachloride, &c.  Finely divided bituminous coal is made into a paste with an equal quantity of heavy oil obtained therefrom and mixed with 0,5 per cent of zinc acetate. The paste is heated to 450 DEG  C. within three hours in a revolving autoclave with hydrogen under 150 atmos. pressure and maintained at this temperature for 1 1/2 hours.  93 per cent of the coal is converted into a product containing 30 per cent benzine and petrol and 7 per cent asphalt.
