Granted: 1903-04-30
Abstract: 11,826. Lake, H. H., [General Electric Co.]. May 24. Rheostats.-A wire resistance 16, Figs. 3 and 6, is wound in two coils or layers on inner and outer sets of blocks 10 of porcelain, which are arranged round a central tubular standard 5, and are held between upper and lower spider heads 3. Only one set of blocks may be used. The blocks 10 fit together as shown in Fig. 6, and are formed with end grooves 12, Fig. 7, and projections 11, which fit on or between radial ribs on the heads 3 and also enable small blocks to be fitted together to form larger ones, as shown in Fig. 3. The wire is wound in grooves 15 on the blocks, and terminates in a binding-post 7 and the lower end of a side rod 6 connecting the heads 3. Part of the outer layer of wire may be cut out of circuit by means of a copper shoe and slide 17 on the rod 6 ; the shoe is pressed against the wire at any desired point by means of a set-screw 20 on the slide. The outer sheet-metal casing 22 between the heads 3 is covered by a hood 23 of the form shown in Fig. 3, or consisting of a lower cone and central chimney surmounted by a conical roof. The rheostat is attached to a wall by means of an offset bracket 4 on the lower head 3.

Granted: 1902-10-09
Abstract: 19,342. Abel, C. D., [Rheinische Metallwaren und Maschinenfabrik]. Sept. 3. Making wheels.-In the manufacture of metal spoke wheels, the partially-formed wheel b, as shown on the left of the Figure, is subjected to an inwardly-directed radial pressure while contained in a matrix d having grooves a for the spokes. This pressure, which may be exerted by a roller n or by pressing or forging, brings the rim c to the desired section, as shown on the right of the Figure, and causes the metal to fill the grooves a entirely, so that the spokes e have the desired finished section. The wheel is held in the matrix by a cover-plate m.

Patent GB-190313746-A (GB)
Title: Improved Method for Operating Signals on Electric Railways.
Inventor: YOUNG SAMUEL MARSH
Filed: 1903-06-19
Granted: 1904-06-18
Abstract: 13,746. Young, S. M. June 19. Electric railways and tramways, signalling on; semaphore &c. signals; signalling between trains.-The invention is described for a single line. The track rails are bonded for use both as return conductors and as track circuits in which alternating signalactuating currents circulate, the different sections being defined for the latter currents by moans of reactances which do not impede the main return current. Direct current from the dynamo 5 flows through the trolley wire 11 and motors of the tramcar 28 to the rails 7, 8, the alternating current passing from the generator by a feeder-wire 12 to the primary 13 of a transformer 14 at the end of each section B, C and returning through a resistance 15 and the rail 7. The secondary 16 is placed as a shunt across the rails, and its circuit completed by the primary 17 of another transformer 18, similarly shunted across the rails, the track circuit for this secondary alternating current being marked off by a reactance 9 in the rail 8 at the end of each section and a second reactance 10 placed across the rails. The secondary 19 of the transformer 18 is thus normally energized and, as in section B, the armature 21 of the relay 20 therein attracted, whereby the core 27 of the electromagnet 23 in the local circuit is pulled in and the semaphore 25 lowered to " line-clear " against the balance-weight 26. In section C, however, the wheels of the tramcar 28 thereon short-circuit the secondary 16, de-energize the primary 17, and allow the semaphore to rise to " danger." In modifications, the signalling and power currents are both alternating, but of different phase or frequency, or current from the power source may be utilized for signalling, provided it be so modified as to be electrically separated or segregated from the main power current. Where a single alternating-current is thus used, one of the track-rails is insulated in sections, and the necessary difference of potential between the two rails produced by the secondaries of transformers, the primaries of which are placed between the feeder-wire and the continuous rail. The feeder-wire may be dispensed with, both currents being carried by the trolley wire, to which the necessary connections for the signalling-circuits are made.

Stereotype.-A. mould for use in casting type-high stereo plates from paper moulds, comprises a baseplate a, head rail a', back wall b, front wall f, a bar z connected by screws y', y<2> to the back wall, and a gate plate q. The rail a<1> is fixed to the baseplate a, and the back wall b is adjustably connected to the rail a<1> by screws b<2>. The plate q is adjustably attached to the base-plate by screws fitting in a groove in the base-plate ; the outer end of this plate q is bent at right-angles. A core c is fitted to the bar z and extends from it at right-angles. The base-plate a has projecting arms a<2> with tapped sleeves for receiving centering-screws a<4>, the ends of which enter recesses in the ends of a rod k of quadrangular cross-section. A scale, corresponding to that generally used in book printing, is marked on the upper side of the rod k. A length adjuster i is adjustably mounted on the rod k, and a width adjuster m is dovetailed within it ; the adjuster i can be secured to the rod by set-screws. A top plate h is fixed to the adjuster m and carries a two-armed lever v, the position of which can be adjusted. The lower end of the lever v is bent, and engages with the base-plate a; a spring, between the plate h and a shoulder on the lever v, presses this lever away from the plate h. The front wall f of the mould is secured to a plate screwed to the lower surface of the plate h. A core g, adjustable, together with front wall f, by means of the length and width adjusters, is fitted above the front wall. Air vents are formed in the front and back walls of the mould.

Abstract: 15,679. Sheffield, F. G. July 15. Butt and flange joints ; clip and sleeve joints.-Relates tothe jointing of flanged pipes by clips and a set of standardized sleeve rings. Figs. 3 an3 4 show the flanges a surrounded by a ring b which has a diameter sufficient to receive in the space c several bolts d having washers d<4> with bosses and nuts for tightening. The bosses may be omitted, and the washers then fit directly on the rings and flanges. A band e may be fitted to prevent blowing out of the jointing-material. Several modifications are shown, in two of which the ring e is of less depth than that of the two flanges, and the bolt pressure is exerted on the flanges by means of the bolt heads, at one end, and external or internal lugs located on the bolts, at the other end. In another modification, shown in Fig. 9, the ring b fits closely, and clip-headed bolts d<6>, secure the flanges. In two other modifications, tse ring is provided with several internal or external bosses adapted to locate a fixed number of bolts and clips in relatively-fixed positions. In another modification, the flanged parts are made integral with the annular parts, which are adapted to co-operate with several clipping-bolts.

Capstan engines.-A horizontal steam engine, carried upon a fixed bed-plate at the top of the capstan, is connected with reversing-gearing, which operates without stopping or reversing the engine. Fig. 2 shows a plan of the arrangement, the bedplate A being fixed to a central pillar. A dished circular member B, indicated in outline, is fixed at the upper end of the capstan barrel, and rotates about the central pillar and immediately under the bed-plate. The shaft D<1>, which is driven from the engine D, carries two pinions E, F ; the pinion E gears directly with the toothed wheel E<1>, which is mounted loosely on the shaft G, and the pinion F gears with the wheel F', which is also loose on the shaft G, through the medium of the wheel F<1>, so that the wheels E', F<2> revolve continuously in opposite directions. The shaft G is driven in either direction, according as the clutch H, which rotates with it, is in gear with the wheels E<1> or F<2>. The capstan drum is driven by a bevel-pinion B<2> fixed on the shaft G, gearing with a toothed ring B<1> secured to the top of the dished member B. The axis of the shaft G is about level with the top of the bed-plate, and the lower parts of the toothed wheel, clutch, &c. pass through slots in the bed-plate and revolve in the hollow part of the dished member.
