Patent GB-190103273-A (GB)
Title: Improvements in and connected with Railway Signalling Apparatus
Inventor: BARNSDALL WALTER GEORGE
Filed: 1901-02-15
Granted: 1901-05-11
Abstract: 3273. Barnsdall, W. G. Feb. 15. Fog and audible signals ; indicators and repeaters, signal.-A treadle-lever a, adapted to be operated by the train wheels engaging and depressing the roller c on one of its ends, is connected at its other end to a rod d, mounted in guides e on a post or support g, which also carries a gong f. The spindle k, mounted in the support g, is provided with a weighted arm m, and with a camp, which engages the stud d<x> on the rod d. The weighted lever l on the spindle k is connected by a chain or wire q to the ordinary signal arm. When the ordinary signal is at ' line clear,' the lever l is held in the position shown, in which case the passage of a train over the treadle a raises the rod d and causes the striker j to sound the gong f. The upward movement of the rod d releases the stud d<x> from the camp, which is then turned by the arm m to lock the rod d in its raised position, the gong being sounded only once. When the signal is put to 'danger,' the lever l falls, and its shorter arm raises and holds up the arm m, so that if another train passes while the signal is still at ' danger,' the gong is struck a succession of blows until the last vehicle of the train has passed over the treadle. The positions of the signals are thus indicated to the driver, without the employment of fogmen &c.

Title: Improved Acetylene-lantern for Vehicles of all Kinds.
Inventor: SCHMITT FRIEDRICH
Filed: 1901-05-09
Granted: 1901-11-16
Abstract: 9663. Schmitt, F., and Schmitt, C. May 9. Acetylene lamps. -In vehicular lamps of the type in which the gas is automatically generated, the steady movement of the water is ensured, notwithstanding the vibration of the vehicle, by the employment of a specially-constructed tube for the passage of the water to and from a special chamber when the generation of gas fluctuates. In the road-vehicle lamp shown in Fig 2, the water from the chamber C traverses the passages c, f under the control of the screw valve e, to the calcium-carbide chamber b, while the gas generated passes to the burner by the tube H and to the upper part of the water chamber C by the tubes A, B. Should the gas be generated too rapidly, the water is forced, by the increase of pressure in the chamber C, to ascend the tube g to the separate chamber D, whence it returns to the chamber C when the pressure of the gas decreases. The flow of the water is steadied by the employment of a telescopic, tapering, or helical tube g, or by placing baffles or perforated partitions therein. In the railway vehicle lamp shown in Fig. 10, which is designed to resist still greater vibration, two or more separate calcium-carbide chambers b with their respective water-controlling valves e are arranged within the water chamber C, the inlet orifices of the valves e being at different levels so that the calcium carbide in one chamber is exhausted before that in the next chamber is attacked. The separate gas tubes A from each carbide chamber b discharge into a common tube B, and two tubes g are employed, one at each side of the lamp.

Title: Improvements in Apparatus for Condensing Steam or for Compressing Air or other Gases
Inventor: STUMPF JOHANN
Filed: 1901-07-18
Granted: 1902-06-25
Abstract: 14,679. Stumpf, J. July 18. Condensers; air pumps.-T he condenser consists generally of a turbine wheel driven vholly or in part by the coudensing-water and effecting an intimate admixture of the water and steam to be condensed in the channels formed by the turbine guide blades and vanes. The apparatus is also capable of use as an air-compressor or as an airpump for a surface condenser. Fig. 1 shows an arrangement in which the steam is admitted between the turbine wheel b and the ring of guideblades c. The shaft a is rotated by a steam turbine, electric motor, or the like. The water enters by the pipe d and chamber f, and the steam enters by the pipe g and flows to the turbine wheel by the pipes h, o. When it is desired to cool the condensing-water for re-use, a fan s is provided to draw a cooling-stream of air through it as it escapes at the periphery. When the apparatus is to be used for compressing air or other gas, the air or gas is admitted in place of steam. Small portions become enclosed between small disconnected columns of water formed in the channels between the guide-blades, and, as these diminish in area towards the periphery, the air or gas becomes compressed as it travels outwards.

Title: Improved Apparatus for Purifying Boiler Feed Water.
Inventor: SCOTT ROBERT
Filed: 1901-07-26
Granted: 1901-10-05
Abstract: 15,198. Scott, B. July 26. Feedwater, purifying.-Relates to apparatus for removing oily matter from water of condensation by the action of an ordinary reagent mixed with a suitable quantity of hard water, which also serves to make np any loss by leakage &c. With the apparatus shown in Fig. 3, the water of condensation is delivered either directly, or after passing through a scumming-tank, into the tank c, which has perforated partitions c'. Hence it is discharged through a vertical slit (not shown) into a trough g, into which are also delivered the liquid reagent from the tank a and hard water from the tank b. The supply to these tanks is controlled by floats a', b<1>, and the discharge by tapered valves a<4>, b', which are operated simultaneously, by means of cords and pulleys, by a float c<3> in the tank c. In this way the supply of reagent and hard water is regulated in accordance with the amount of water to be treated. The water and reagent thus supplied are mixed together in flowing down an inclined trough with baffles, and are delivered into a tank from which free oil and saponified oil are withdrawn at the top and sediment at the bottom. Hence the water passes through a suitable filter to the boiler. The reaction tank and filter may be combined in one vessel, especially in apparatus for use on board ship. Fig. 7 shows a modified arrangement of valves for regulating the supply of reagent and hard water in cases where the water to be treated is supplied under pressure by a pump. The water to be treated is supplied at d, and raises a valve c<8> against a spring, more or less, according to its pressure. This valve is connected to the tapered valves a', b' for regulating the supply of reagent and hard water. In another modification, the reagent and hard water are supplied by small pumps of adjustable stroke operated together with the feed-pump.

Filed: 1901-10-21
Granted: 1902-01-16
Abstract: 21,050. Walker, D., and Wood, J., [trading as Nottingham Warping Co.]. Oct. 21. Yarns, warping.-In warping-machines, the bobbin wires d of the jacks or bobbin stands, instead of being driven into the usual rails a, have an elastic connection with them. This is effected by making the hole b slightly larger than the wire and using a rubber &c. ring or strip e or h to act as a buffer which yields to the tension of the yarn. The ring may be cemented to the rail a or to the wire, and may be held in place by a plate f.

Patent GB-190205010-A (GB)
Title: Improvements in Electric Meters.
Inventor: BLANCHET ARTHUR
Filed: 1902-02-27
Granted: 1903-01-29
Abstract: 5010. Blanchet, A. Feb. 27. Energy meters.-In an alternating-current induction motor meter, having a rotary conductive cylinder or disc A acted on by current and pressure coils B<I>, BE, the magnetic fluxes in these are put in quadrature, when the main current and pressure are in phase, by making the circuit of the pressure coil BE highly inductive, and supplying the current coil B<I> from the secondary of a small transformer T', the primary of which is in the main circuit. In the form shown, the current and pressure coils are provided with two-pole iron cores b, d, placed at right-angles to each other, the magnetic circuits being completed through a stationary laminated iron armature C, below the rotary disc A. The disc is retarded by permanent magnets M<2>, and its spindle drives a counter. The time-constant of the secondary circuit of the transformer T' is made equal to that of the pressure coil BE, by adjusting either the height of the stationary armature C, or a resistance R<1> in the secondary circuit, or a resistance R<3> closing the circuit of a third winding on the transformer, or an air gap in the magnetic circuit of an inductance coil in circuit with the pressure coil. To obtain a starting effect independent of the main current, a winding E' on the core b is supplied with current from a secondary winding provided either on the core d of the pressure coil B<E>, or on the core of an inductance coil in circuit with the pressure coil ; or the winding E' may be placed in a non- inductive shunt circuit of high resistance. The same effect may be obtained by providing an adjustable laminated iron plate above the disc A, to shunt a part of the magnetic flux of the pressure coil BE. In a modified arrangement, the coil BE and core d are replaced by two coils on rectangular cores with small air-gaps through which the disc travels ; the two cores are constructed as extensions of the rectangular core of the transformer T', which is placed below the disc A. In another arrangement, the current and pressure coils B<I>, BE are vertical solenoids acting directly on the disc A, without iron cores. For three-phase currents, two sets of coils are arranged to act on two conductive discs or cylinders carried by a single spindle.

Title: Improvements in Stringed Musical Instruments
Inventor: CLARK RUFUS JESSE
Filed: 1902-04-08
Granted: 1902-05-15
Abstract: 8213. Clark, R. J., and Leprohon, M. E. April 8. Instruments with sonorous strings; pianofortes.- In a combined piano and bowed instrument, the piano action is of an ordinary kind, the soundboard and strings being shown at 18, 17 respectively, and the hammers and keys at 24, 11. The damper wires 25 are connected to levers 27 provided with projections 31, in which rest long thin soundboxes 32. One of these is shown separately in Fig. 7. Their rear ends have lugs 36, which rest on and are loosely attached to a hollow rounded rail. This rail acts as an additional resonator. The front ends of the sound boxes are guided by pins 44, and they carry on their upper surfaces two or more strings which are tuned in unison. A board 47, shown separately in Fig. 5, extends across the strings and carries an endless band or bow 54, to which resin is applied by a fixed bracket 61. The bow is stretched between pulleys 58, one of which is driven by a motor, preferably electric. The lower section of the band is supported against the pressure of the strings by rollers 71. The rear ends of the levers 27 carry damper wires 76. When a key is struck, the corresponding piano hammer is actuated, and also the corresponding box 32 is raised, and the strings upon it are pressed against the moving bow. The pressure of the strings on the bow is regulated by soft adjustable pads 70, which yield slightly and allow the pressure on the bow to depend on the force applied to the keys.

Title: Improvements in Non-Refillable Bottles, Jars or other Containers
Filed: 1902-04-21
Granted: 1902-11-13
Abstract: 9230. Clark, A. M., [Payton, J. Y., Cox, G., Goolsby, O. K., and May, F. J.]. April 21. Measured quantities, delivering. - Relates to bottles, jars, jugs, &c., which cannot be refilled after having once been emptied. The neck B of the vessel is formed with an outlet passage D', an internal lug or rib F, and a partition C having an outlet port C'. A dispensing cylinder H, having a longitudinal slot H', Fig. 5, is inserted in the neck between the partition C and the rib F, the slot H<1> permitting its insertion past the rib. The cylinder is adapted to receive the piston I<2>, the lug I<3> of which fits in the slot H<1>, the lugs I<3>, I<4> on the piston acting as stops in conjunction with the rib F. The stem I<1> of the piston is of rectangular section, and passes through a corresponding hole in the cap or stopper G, which is revolubly secured in position by spring detents G<6> engaging in a groove in the neck. This groove is formed with ratchet teeth or projections, which permit the stopper, piston, and cylinder to be rotated only in one direction. In the positions of the parts shown in Fig. 1, the cylinder H closes the port C', and the slot H<1> and the notch G<9> in the flange G<7> of the stopper register respectively with the inner and outer ends of the passage D', so permitting the discharge of the liquid previously taken into the cylinder. To refill the cylinder from the vessel, the piston is pushed into its full extent, so that the lug I<3> clears the rib F, and is then rotated until the lug I<4> engages the rib, thus bringing the slot H<1> over the port C' and closing the outlet D'. The cylinder is then charged by inverting the vessel, and drawing out the piston until the lug I<4> abuts against the stopper, after which the piston and cylinder can be rotated through another half revolution, to bring the parts into the discharging position, as shown. The inward movement of the the piston, which is necessary before the cylinder can be rotated from the discharging to the filling position, ensures the discharge of any liquid which may have been introduced into the chamber. It also reveals the presence of any solid obstructions, which, if inserted, would prevent the full inward movement of the piston. In the modification shown in Fig. 9, the rib F is shorter, and the plunger I, Fig. 14, is formed without the lug I<4>. The head I<3> of the plunger is adapted to work in the slot H' of the solid cylinder H, Fig. 15, the liquid displaced from the slot H<1> by the depression of the plunger being discharged through the outlet D<1>. The stopper G is also modified.

Title: Improvements in Variable Speed and Reversing Gear
Inventor: SHEPPARD HERBERT CHARLES
Filed: 1903-02-12
Granted: 1903-06-11
Abstract: 3368. Sheppard, H. C., and Milburn, F. Feb. 12. Toothed gearing.-Relates to variable-speed and reversing epicyclic gearing, in which the changes are effected by controlling the motion of the case containing the epicyclic train. a is a main shaft mounted in bearings a<1> from which a coaxial shaft b is driven by gearing in the loosely-mounted case d. The pinion c on the shaft a gears with a pinion c' mounted on a stud in the case d. An axle c<3> in the case d carries toothed wheels c<2>, c<4>, of which c<2> gears with c', and c' with the pinion c<5> on the shaft b. One of the bearing-sleeves of the case d carries a worm-wheel e driven by a worm, the shaft of which carries a gear-wheel f which gears with a wheel g on a feathered shaft carrying a friction-wheel. The friction wheel is adjustable by a shifting-lever h<2>, and bears against the face of a spring-mounted disc i driven from the main shaft by gearing a<2> &c. The position of the friction-wheel on the disc i governs the speed and direction of rotation of the case d and, through it, the speed and direction of rotation of shaft b. When it is desired only to ieduce or reverse the motion of shaft b, the disc i may be mounted on the shaft a and the friction wheel move on one radius only. An adjustable band brake may be applied to the case d, or an eccentric mounted on one face may actuate the piston of a liquid-pressure cylinder, the ends of the cylinder being connected by a tube with a controlling-valve, when it is desired to vary the speed only by decreasing it.
