Title: Improvements relating to Incandescent Spirit Lamps
Filed: 1903-11-16
Granted: 1904-08-11
Abstract: 24,927. Lake, H. H., [Akt.-Ges.f³r Spiritus- Beleuchtung und Heizung]. Nov. 16. Incandescent vapour lamps.-Heat is conducted from the flame to the copper vaporizer d by a copper rod a, c, which is cranked to pass through slots in the parts e, i of the mixing-tube. The tube e is attached to the rod c by lugs f. The spirit is conducted to the vaporizer by a feeding- wick, which is first passed through, and then turned over, an inner wick-tube q. In order to compress the wick without rendering its insertion in the' tube q difficult, the upper end w of the tube is contracted. The outer wick-tube l is made of german silver to minimize the conduction of heat to the reservoir. The burner is initially heated by introducing spirit through an opening t, and igniting it in the cup s. The deflection of the starting flame by draughts entering the opening t is prevented by forming the burner basket opposite the opening with a shield u or an unperforated part, and the entrance of the starting name into the mixing-tube e is prevented by a conical baffle v. The quantity of vapour supplied by the nozzle k is regulated by a conical plug n, carried by a sleeve m which is operated by a handle p. The plug n also serves to close entirely the orifice of the nozzle k when it is desired to extinguish the flame. An expansion chamber o is provided in the upper end of the sleeve p to ensure that the vapour shall be supplied in a steady stream to the mixing- tube. The aperture t may be provided with a pivoted flap, which is opened when the handle p is turned to open the burner nozzle, and falls by its own weight to close the aperture when the handle p is turned back to cut off the vapour supply and extinguish the flame.

Title: Variable Speed Gearing
Inventor: FAIRWEATHER WALLACE
Filed: 1904-01-08
Granted: 1904-09-01
Abstract: 517. Fairweather, W., [Chamberlain, C. K.]. Jan. 8. Eccentrics and eccentric rods. - A shaft is driven at a variable speed by ratchet gearing, actuated from a driving-s h a f t by means of balanced eccentrics, the throw of which is adjustable. Eccensheaves 6, Figs. 1 and 2, are mounted on guides 5 on discs 4 fixed to the driving-shaft 1. Weights 8, coupled by a crosshead 9, are also mounted on each of the guides 5. Eccentric straps on the sheaves are coupled by rods 14 to sleeves 23, loosely mounted on the driven shaft 20. To an arm 25, Fig. 7, on each of the sleeves 23 is pivoted a spring-controlled link 28 carrying an adjustable head and block 27. The block 27 acts as a pawl and is adapted to engage the flange 22 of a pulley 21 fixed to the shaft 20. In order to adjust the throw of each eccentric and the consequent movement of the pawl 27 and the shaft 20, a shaft 40, mounted within the shaft 1, carries a bevelwheel, gearing with bevel-wheels on the ends of screws engaging the eccentric sheave 6 and crosshead 9 respectively. By altering the speed of the shaft 40 relatively to the shaft 1, the eccentric sheaves are moved to adjust the throw, and the weights 8 receive a corresponding movement to keep the sheaves balanced. In order to retard the shaft 40 relatively to the shaft 1 and so increase the eccentric throw, a collar 47 on the shaft 40 is journalled in a bearing provided with a hinged cap 49, which is forced down by means of a screw 50 for the purpose of braking the shaft. When the eccentric sheave reaches the limit of its travel, it actuates a lever 52, which is coupled by means of links 53, 55 and a bell-crank lever 54 to the screw 50. When the lever 52 is moved, the screw 50 is actuated to relieve the braking pressure. In order to speed up the shaft 40 when it is desired to decrease the throw of the eccentrics, a loose pulley 57 on the shaft 40 is driven through belt gearing, from a pulley on the shaft 1 at a higher speed than this shaft. A clutch member 58 on the shaft 40 may be thrown into driving engagement with the pulley 57 when the throw is to be decreased. The member 58 is actuated by a lever 60, connected, through a pin-and-slot coupling, with a link 64 jointed to the lever 54 so that, by turning the screw 50, the member may be moved. A projection 67 on the eccentric sheave engages a conical recess in the member 58 and serves to withdraw it out of engagement with the pulley 57 when the sheave is moved concentric with the shaft 1. One eccentric strap may be employed for two rods, one of the rods being fixed, and the other pivoted to the strap.

Title: Improvements in or relating to Wireless Telegraphy.
Inventor: FOREST LEE DE
Filed: 1906-03-03
Granted: 1907-04-03
Abstract: 5258. Forest, L. de. March 3. Telegraphs.-Relates to responsive devices for electromagnetic waves in which the sensitive element is a gaseous medium maintained in a condition of molecular activity by means of a flame or by heat radiations. A number of modifications are shown in the Specification, in all of which an antenna A and an earth connexion E from the oscillation circuit, and a battery B and telephone receiver T form part of a local circuit. The electrodes F, Fig. 1, which form part of the oscillation and the local circuit, are heated by the flame of a Bunsen burner D. This allows the current of the local circuit to pass across the heated gap every time an electric oscillation passes. The electrodes may be made in the form of plates, or the flame may form one electrode, or each circuit may have a separate gap placed adjacent to be heated by the same flame, or the electrodes may have sufficient resistance to be heated by current from a dynamo. Fig. 7 shows a form in which the electrodes consist of incandescent lamp filaments C, which are sealed in a partly exhausted receptacle I, and each of which has a separate battery H. The telephone T is arranged either in series with the battery B or in shunt with the filaments C. The gas in the receptacle may be air or mercury vapour or a gas containing compounds of the halogens. A coil L couples the antenna circuit with the local circuit, and with a condenser R enables the two circuits to be tuned together. Platinum balls may be substituted for one or both of the filaments C, and a high-potential alternating current obtained from an alternator and a transformer may be used in place of the battery B. Fig. 14 shows electrodes F, F<1>, the latter having a core f of potassium chloride, between which is an electric arc, the flame of which is deflected towards another electrode U by a magnet W. The arc may be enclosed, or it may be used to vaporize some suitable material placed in the gap.
