Title: Improvements in the Manufacture of Peat Fuel and in Apparatus therefor
Filed: 1904-06-18
Granted: 1905-06-15
Abstract: 13,822. Whittaker, L., and Whittaker & Co., C. June 18. Moulding peat by extrusion. Ground, dried peat is fed into a kneading cylinder containing a worm or screw blades of gradually-decreasing pitch. This cylinder has a tapering or restricted orifice 26 and preferably is steam-jacketed. The feeding- device may consist of a rotating disc having scrapers, and receives the peat from an edge-runner mill. Compressed peat is extruded from the kneader and may be cut into lengths, these being conveyed to a second cutter, where they are divided into briquettes. The second cutter preferably consists of wires or blades mounted on a rotating frame. Instead of being cut up at once, the peat may be further compressed, falling from the kneader to the hopper of another extrusion press 28 worked by a plunger 30. This second press is also steam-jacketed, as shown, and has a valve 32 to admit air behind the compressed peat on the return stroke of the plunger. This valve may be of any kind, and may be placed in the plunger. A worm press may also be used. Each finished briquette is preferably received on a pivoted pallet adapted to support it and deposit it on a tray or wagon for conveyance to a drying room or to a press for marking it in any desired way. The Provisional Specification describes a press having an upper fixed plunger and a lower vertically-movable one, over which slides a mould. The mould is moved, and raises the lower plunger, on which a briquette is placed. When lowered, the bottom plunger is arrested by stops, and the mould slides down, allowing the briquette to be removed.

Title: Adjustable Screw Bolt.
Inventor: WEAVER WILLIAM ARTHUR
Filed: 1904-09-20
Granted: 1905-04-06
Abstract: 20,222. Weaver, W. A. Sept. 20. Work-holders.-Relates to a device for clamping work to a machine bed or table, drawing liners i n t o cylinders, a n d similar purposes. It consists of a screwed bolt b formed with a block a through which passes the chain d carrying the T-shaped block e. The block a is cast with a cavity f into which opens a passage g at an angi@ of about 60 degrees. In clamping work to a machine table, the bolt head e is introduced into one of the table slots, and a plate is placed under the nut c with its ends resting on the work and suitable packing. On adjustment of the chain d and tightening of the nut c, the block a is raised and the chain caused to bind round the corners of the passage g. The upper part f of the passage is arched, and at one side open, to allow of the ready insertion of the chain, while its width is such that the pull of the chain is exactly in line with the bolt. The chain is of the multi-link kind, except for large sizes and heavy work, when it is preferably of the solid link kind. For heavy work, the bolt is tapped into the block, and the device may be duplicated by having passages in the block a for two chains. In modifications, parts of the blocks may be dispensed with, so that the bolt may be directly above the part h, in which case, however, a direct pull is not obtained ; the nut for tightening the chain may be on a screwed rod attached to the lower end of the chain, or an ordinary link chain may be used with a cruciform recess. The clamping-device can be used at an angle owing to the flexibility of the chain, and by using two blocks with one chain the device may be used for supporting purposes.

Title: Improvements in and relating to the Control of Electric Motors
Inventor: CAROLAN EDGAR ALFRED
Filed: 1904-09-23
Granted: 1905-07-27
Abstract: 20,550. Carolan, E. A., [General Electric Co.]. Sept. 23. Motors, controlling.- Series electric motors subject to varying loads, and particularly motors for automobiles, are controlled by having their field windings over-wound and shunted by a resistance of high temperaturecoefficient, so that normally only a small current passes through the field, but, when the motor is subjected to a heavy load, the resistance of the shunt increases and more current passes through the fields, thereby decreasing the speed and the current. The arrangement of connections is shown in the figure, in which a controller has three working positions and a set of four fixed and four movable contacts. In the first position, the resistance 4, preferably of iron wire, is connected in series with the field 3 and the armature 2 of the motor and with the battery, thus serving as a starting-resistance. In the second position, the resistance 4 is cut out, while, in the third position, this resistance is connected in parallel across the motor field. For additional speeds, additional fingers must be provided on the controller. A ratio of 3 to 1 between the resistances of the shunt 4 and coils 3 gives an efficient arrangement.

Granted: 1905-11-30
Abstract: 26,874. Wrightson, T. G., and Ring- quist, J. M. Dec. 9. Lifts; shoots; loading and unloading; tipping-apparatus.-A combined hoisting and tipping apparatus for coal wagons and the like, comprises a guided platform connected to an electric hoisting-motor and also to balance weights, the arrangement being such that the platform automatically tips in one direction when the balance weights strike against stops, connected to a floating pontoon so as to fall when the pontoon rises and vice versÔ. Fig. 1 shows the platform a connected by ropes c to the motor-driven drum e so that it normally tends to tip in a clockwise direction but is prevented by ropes d attached to balance weights h. A shoot k is carried by a floating pontoon j so as to rise and fall therewith. The stops l are supported by ropes passing over the pulley n. The tension in the rope d is relieved when the balance weights strike against the stops, and the platform tips automatically. The platform a is guided and prevented from tipping in the wrong direction by friction rollers o<2>, o<3> engaging three sides of the vertical pillar p. This apparatus may be used with the conveying and delivering apparatus described in Specifications No. 1191, A.D. 1896, and No. 26,939, A.D. 1898, in which case the feeding-hopper of the conveyer would be mounted on a hoist and in some cases made to carry the stops for the balance weights described above.

Title: Electric Incandescence Lamp with Incandescence Body Fused in the Conducting Wires.
Inventor: THOMPSON WILLIAM PHILLIPS
Filed: 1904-12-19
Granted: 1905-01-19
Abstract: 27,714. Thompson, W. P., [Deutsche Gasgl³hlicht Akt.-Ges. (Auer Ges.)]. Dec. 19. Incandescent lamps. - Filaments are united to leading-in wires bv fusing the latter over them, in an inert atmosphere if necessary. The glass foot or stem a carrying the leading - in wires b is mounted on a spring holder e, and the filament c suspended from a hook f. A support g presses the filament against the leading - in wires b, which may be bent to receive it. One wire b is connected, preferably between the stem a and the filament c, by a metal electrode h to one terminal of a source of current, the other terminal of which is connected to a metal or carbon electrode l. This electrode is placed in contact with the end of the wire b and withdrawn, so as to form a quicklybroken arc, thereby fusing the leading-in wire over the filament. The operation may be repeated if necessary. After the fusion, the filament is released by depressing the hook f, which is under spring tension. The fusion may be effected by introducing the wires into an arc deflected by a magnet, but the above method is preferred. Several filaments and stems may be mounted side by side. If the material of the filament is attacked by air, the apparatus is placed in an inert gas, contained in a closed vessel, stuffing-boxes or the like being provided for the electrodes ; or the inert gas may be passed, if light, down a tubular vessel open at the bottom, as shown in Fig. 6. One electrode h is introduced through a projection i in such a way as to allow of some play, the other through a projection k which permits a to- and-fro motion. If the apparatus is used in a room free from draughts, the vessel may be dispensed with, and a current of the inert gas, such as nitrogen, may be allowed to flow upon the parts to be heated by the arc. A self-induction coil and a regulating resistance are inserted in the electric circuit.

Granted: 1906-02-01
Abstract: 146. Rost, 0. Jan. 3. Making taps.- Taps are screwed, grooved, and cut - off from bar stock fed through a hollow spindle of ordinary type. A cam shaft 8, Fig. 1, is driven through intermediate gearing from a stepped pulley 1, and carries drums 9, 10, operating the spindle gripping and feeding mechanism, and the milling and screwing slide respectively. A disk 20 operates the cutting-off slide, and a cam 17 controlling the clutching of the driving- pulley 24 'is driven through bevel gearing 15. The milling-cutters are adjustably mounted, and are driven through bevel wheels and pinions from a central wheel on the shaft of a belt pulley 30. The screwing-head is independently driven. The supporting slide 28 is traversed longitudinally and transversely by levers operated by the camgrooves 13, 14. The stock is fed against a stop 46, and the head 45 is brought in line with, and is traversed along, the stock. The work spindle rotates three times as fast as the head 45 so that, when the former is stopped by the cam 17 at the end of the traverse, the head will unscrew itself. The milling-cutters are now brought into line and traversed to cut the grooves, the spindle being still stationary. The milling-cutters are then withdrawn, the spindle is set in motion, and the slide 27 advanced to cut off the tap.

Title: Printing on Leather.
Inventor: LAMB MORRIS CHARLES
Filed: 1905-05-26
Granted: 1906-05-24
Abstract: 11,049. Lamb, M. C., and Rennie, J. D, G. May 26. Printing leather.-Leather is printed in coloured patterns and without obscuring the grain, by using thecoal-tar and natural dyes ordinarily employed for dyeing or staining leather. For ordinary printing, solutions in water, alcohol, benzine, or other hydrocarbon, are used. Mucilaginous thickening, such as gelatine, gum tragacanth, carrageen, linseed, farina, starches, soaps, alginates, or sulphated oils, may be added, using the minimum proportion, so as not to obscure the grain or retard the penetration of the dye. In the case of natural dyes, the mordant is mixed with the dye, or is applied to the leather before printing. For example, to obtain black on a pale maroon or violet ground, the ground is obtained by aqueous solution of logwood extract and aluminium sulphate, and the print is made in ink containing water, farina, ferrous sulphate, glycerine, linseed oil, and commercial iron nitrate. For discharge printing, a ground, for example, fast red, is formed by dyeing, and a print is made with a thickened solution of hydrosulphate of soda. For resist printing, a print is made with a paste of superfatted soap or wax, and then the leather is dyed or stained as usual ; multicolour effects may be obtained by alternate printings and dyeings. Printing from stencil plates is mentioned in the Provisional Specification.

Abstract: 21,589. MacConnell, H. C. Oct. 24. Right to Patent relinquished. Lathes; milling.-In a machine for trimming the straight and curved edges and the inside faces of curved stereotype plates, two standards A, Figs. 1 and 2, connected by cross-stays, support a cylinder D, each being provided with four antifriction rollers a, which are adapted to bear in a groove d on the surface of cylinder and of which two are adjustable by screws a<1>. Mounted in bearings B', B<2> and extending through the cylinder D is a stationary shaft B carrying a saddle C on which the plate to be trimmed is supported while being pushed into the cylinder D, where it rests on diametrically opposite ribs or ledges formed on the interior thereof. The inward motion of the plate is limited by a spring stop n, pivoted at n<1> to the saddle and capable of being depressed for the removal of the plate after trimming by a cord or wire n<3> attached to a short arm on the stop, and a bolt n'. Round the periphery of the cylinder D is a worm-wheel G, which gears with a worm G' on a tubular shaft G<2>, carried on and capable of being rigidly connected with a shaft H by a friction clutch operated by a handle I<1>. The shaft H is driven by bevelgearing h<1>, h<2>, h<3> from the main shaft E of the machine. On the shaft E are two cutters e, which trim the curved edges of the plate as it is carried round by the rotation of the cylinder D. A frame K mounted by means of hubs k<1> on the shaft B supports an adjustable knife k, which trims the internal ribs of the plate. Cutters ,f, on a shaft F driven by bevel-gearing from a shaft operated by spur-wbeels from the shaft E, serve to trim the straight edges of the plate as it is pushed into the cylinder D. A weighted catch J which engages a recess in the circumference of the cylinder D is provided for automatically locking the cylinder after completing a revolution. The plate to be trimmed is placed on the projecting portion of the saddle C and slowly pushed into the cylinder D, during which motion its straight edges are trimmed by the continuously-running cutters f. The catch J is then thrown out of operation and the cylinder put into action by means of the handle I<1>. The internal face and the curved edges are thus trimmed, and at the same time the gate is removed, and falls on a guide L clear of the machine. After stopping the cylinder D, the stop n is depressed and the trimmed plate pushed out by the next plate on to a belt conveyer M.
