Title: Improvements in Automatic Fire Extinguishing Apparatus.
Inventor: SIMPSON HENRY
Filed: 1904-03-11
Granted: 1905-03-09
Abstract: 5984. Simpson, H., and Thomlinson, R. March 11. Automatic appliances; alarms, fire and temperature; extincteurs. - Relates to a liquid-expansion device, similar to that described in Specification No. 22,666, A.D. 1900, operating an extincteur, water tank valve, or other apparatus, and also sounding an alarm. Tubes 1, 1<a>, Fig. 1, contain an expansible fluid, in which is placed a flexible capsule 2, the interior of which communicates with a closed rubber vessel 3, so constrained by a tube 4 that it can only expand axially when the capsule is compressed. A sliding tube 5 is actuated by this expansion, and its motion may be used to operate the extinguishing-apparatus directly, or by releasing a spring or loaded lever, or by closing an electric circuit. A differential arrangement is, however, preferred, and a slow-acting device B, of similar construction, is added. In the latter, the liquid used does not affect the rubber, so that the capsule may be dispensed with. A lever 7, Fig. 2, pivoted on the sliding tube 5 of the slow-acting device B, is tilted by a catch 10 on the quick-acting device A, and a roller 8 and wire 9 are released. A weighted lever 12, Fig. 3, withdraws a bolt 14, thereby allowing a weight 15 to drop and mix gas-producing chemicals in an extincteur 19, a valve 17<a> is opened to allow the extinguishing-material to escape, and contact is made at 21 to sound an alarm. A tank containing fluid under pressure may be used instead of the extincteur. Fig. 7 shows the electrical method of operating. Contacts E<1> or E' meet contacts F<1> or F<2> to ring a bell 22, F' being on the slow-acting device B, and F' fixed, while afterwards C' or C<2> makes contact with D<1> or D'to energize a magnet 25. The latter attracts a bar 25<a>, Fig. 9, and a detent 23, and hook 24 are released, when a weighted lever comes into operation as before, Fig. 3.

Title: An Improved Speed Indicator applicable also as a Speed Regulator
Inventor: RUCK RICHARD MATTHEWS
Filed: 1904-06-23
Granted: 1905-04-27
Abstract: 14,201. Ruck, R. M. June 23. Speed indicators.-An apparatus for indicating the speed of machinery, motor cars, or trains, or the pitch of the note given by a siren, may also be used for recording and regulating the speed, and for giving audible or visual warning of the attainment of a certain speed. A clock-driven pointer A carrying an electric contact-device A' rotates in front of a wheel B driven through a variable-speed gear from the machine or vehicle. A shaft e, connected to the wheel B through gearing D, E or D<1>, E', is driven from a cone F. A belt H or other frictional connection between the cones F, G moves with a nut J<1> on the screw J. A double clutch N, Fig. 2, on a sliding shaft m is held in engagement with a bevel-wheel M' by a spring Q until the wheel B overtakes the pointer A and the contact-device completes the circuit of an electromagnet C. The clutch is then drawn into engagement with the bevel-wheel M', and the direction of rotation of the screw J is reversed and remains so until the wheel B lags behind the pointer. The rapidity of the reversals may be adjusted, and contact-devices are so placed to be actuated by the nut J<1> as to ensure the reversal at either end of its travel. An index K on the nut J' indicates the speed, and the nut may actuate a marker in connection with a recording-drum, which may be driven by the same clock as the pointer A. The nut may also actuate the switch of an electric bell, lamp, or other devine, and may control valve gear governing the supply of motive fluid, or the rheostat switch of an electric motor, or the brake mechanism of the vehicle. Other forms of variable-speed gear and contact-device may be used, and the clock driving the pointer A may serve also as a timepiece.

Granted: 1905-05-04
Abstract: 27,199. Siemens Bros. & Co., [Siemens Schuckertwerke Ges.]. Dec. 13. Steering-gear. - In electrically-driven plants in which large masses are accumulated quickly or have their direction of motion rapidly reversed by means of a motor supplied with current from a starting- current generator, such as ship's steering-gear, the excitation of the generator is accelerated by impressing upon its field winding a higher pressure than is required for the normal exciting-current, the excess pressure being absorbed, when the current has reached a steady value, by a resistance of small inductance preferably permanently connected in series with the field winding. In Fig. 2, which shows the preferred arrangement, g represents a continuous-current motor supplied with current from a separately-excited generator b. A resistance e and an adjustable rheostat f are included in the circuit of the field a, which is connected to the source of excitation through a suitable reversing-switch c. The application of the invention to a shunt-wound starting-current generator is also described.

Title: Improvements in Transmitters for Wireless Telegraphy.
Inventor: THOMPSON WILLIAM PHILLIPS
Filed: 1905-05-22
Granted: 1905-09-14
Abstract: 10,710. Thompson, W. P., [Ges.-f³r Drahtlose Telegraphie]. May 22. Wireless telegraphy.-In wireless telegraphy, the home transmitter is rapidly tuned to a distant transmitter by means of a detector connected thereto, which detector is switched off whan the home transmitter is used. Fig. 1 shows the arrangement whao the sparking-device is placed directly in the aerial. The detector circuit. comprises a condenser 12, electrolytic detector 8, choking coils 10, telephone 11, and battery 9, and can be connected to the aerial circuit by the switch 14. To time the transmitter, the sparking- device 3 is short-circuited by the switch 13, and the detector circuit is switched into the transmitter circuit. The capacity 4 and inductance 5 are adjusted till the maximum sound is heard in the telephone 11. The capacity 12 is then enlarged and the adjustment repeated, and so on until sharp tuning has been obtained. The switches 13, 14 are then reversed and the transmitter is ready for use. The switches 13, 14 may be combined to form a single switch. If the capacity of the condenser 12 has not become large enough to be neglected relatively to the capacity of the condenser 4, the tuning is slightly altered when the detector circuit is switched off. In this case the arrangement shown in Fig. 3 is adopted, the condenser 15 and detector 8 being in parallel with the capacity 4. If the capacity 15 is small compared with the capacity 4, the tuning is not altered when the detector circuit is switched off. When a closedcircuit transmitting-system is used, the exciting- circuit must also be tuned. This is effected by varying the induction in the exciting-circuit until the maximum deflexion is obtained in an ammeter switched in the aerial circuit.
