Title: Improvements in Illuminated Signs
Inventor: KNOWLES WILLIAM HUMPHREY
Filed: 1903-04-20
Granted: 1903-06-11
Abstract: 8894. Knowles, W. H., [Lee, C. E]. April 20. Advertising; signs.-Consists of improvements in changeable or disappearing illuminated signs. A box, internally illuminated by a lamp or other means, is provided with specially-constructed sides, Figs. 1, 4, and 7. The sides in Fig. 1 consist of glass or other transparent plates 4, 4, and a layer 7, 7 of cardboard, asbestos, or the like, in which an electric conductor 6, 6 is embedded. The rest of the space between the plates is filled with wax, a supersaturated solution of camphor in dilute alcohol, or any suitable material which is opaque at ordinary temperatures and translucent at higher temperatures. Letters or symbols are formed in the cardboard &c. by means of a series of perforations 8, 8, in which the electric conductor is coiled as shown. When the wax &c. is cold, the letters are not lit up, but become so when the wax &c. is melted by passing a current through the wire 6, 6. The sign becomes opaque when the wire is no longer heated. The wire may be coiled in the wax &c. as in Fig. 4, so as to form the outlines of the letters or symbols, suitable insulation being interposed between the parts of wire that cross. On heating the wire, the wax in the immediate proximity thereto becomes melted, forming transparent lines in the wax, which allow the light from behind to pass through. The letters may also be painted or permanently impressed on one of the backing glass sheets, as at 9, Fig. 7, and wires 6 arranged so as to melt all the wax, when a current is passed through the network. The wax and the glass backing may both be variously coloured in different parts, and other means of heating the wire may be employed.

Patent GB-190320943-A (GB)
Title: Improvements relating to Speed Change Gear.
Inventor: ENRICO GIOVANNI
Filed: 1903-09-29
Granted: 1903-10-29
Abstract: 20,943. Enrico, G. Sept. 29. Clutches; toothed gearing. - Relates to the clutch mechanism of variable-speed gears, in which a liquid under pressure is used to bring the clutch members into operation. The driving-shaft B and the driven shaft A are enclosed in a box C containing oil. A pump Q draws oil from the box through the orifice 1, and forces it into the tube 2 and telescopic tube 3, from which it passes through the orifice 0 into the inner tube 4. If the pressure exceeds a certain amount, the valve D is lifted, and the oil returns through the tube 5 to the box. The shaft B carries gearwheels b<1>, b<2>, b<3>, b<4> gearing with corresponding wheels a, a<2>, a<3>, a<4>, each of which consists of two parts. The part h carrying the toothed crown rotates freely upon, and is capable of sliding upon, the hub c of the disc or other part d which is keyed to the shaft A. Springs e normally force the parts as near together as stops l will permit, and in this position the part h runs freely upon the hub c. The disc d has a coned periphery f, which gears with a corresponding internal coned surface on the part h when the parts composing each wheel are forced apart by means of the liquid under pressure being admitted through ports g in the shaft A, and through ports p in a piston P formed on the end of the shaft 4. The opposite end of the shaft has a collar F with which the operating-lever engages to bring the piston into position to put any wheel a<1>, a<2>, a<3>, a<4> into action. The spring e in each wheel returns the movable part to its original position, when the pressure is removed by withdrawing the piston P. The oil then passes through the ports g into the hollow shaft A, and is returned through the ports m, n to the box C. Small holes i between the teeth of the wheels allow the oil to escape slightly by centrifugal action while the two parts of each wheel are in engagement, and facilitate the complete discharge of the oil after the parts are released. The parts of any wheel a<1> &c. may be brought into, or thrown out of, action by respectively closing and opening the valve D by means of a pedal or crank-lever acting upon the lever G.

Patent GB-190412704-A (GB)
Title: Improvements in and relating to Fluid Pressure Brake Apparatus
Filed: 1904-06-04
Granted: 1904-07-07
Abstract: 12,704. Lake, H. H., [New York Air Brake Co.]. June 4. Brakes.-The passage, through which the triple valve of a fluidpressure brake system, such as an automatic air-pressure brake, com municates with the brake cylinder, is provided with a valve which, when an emergency application has been made, reduces the brake-cylinder pressure, after a predetermined time, to that required for a service application, the object being to obtain the maximum brake effect both at the maximum initial speed of the train and afterwards at the reduced speed. In the form shown in Figs. 1 and 3, the passage which connects the triple valve 5 and the brake cylinder 3 is provided with a tube 17, which places the brake cylinder and the small chamber 19 in communication by means of the grooved stem of a valve 13 and the small aperture 18 in a tubular casing 12 surrounding the valve. When an emergency application has been made, the air in the brake cylinder flows slowly through the aperture 18 until the pressure in the chamber 19 is sufficient to depress the diaphragm 8 slightly against the action of the spring 9. The diaphragm carries the tubular casing 12, which is thus lowered from its seat 16, and the air in the brake cylinder then flows suddenly into the chamber 19 to depress the diaphragm at its lowest position. The length of the rod 20 secured to the valve 13 permits only a slight lowering of this valve, which, as the diaphragm is depressed, opens to allow air from the brake cylinder to flow down the grooved stem, through the valve and openings 22, into the atmosphere. When the brakecylinder pressure has been thus reduced to serviceapplication pressure, the spring 9 raises the diaphragm to close the valve 13. The aperture 18 may be supplemented by another aperture in a spring-pressed valve for relieving the brakecylinder pressure in a service application as soon as it exceeds the maximum of the ordinary serviceapplication pressure. In the form shown in Fig. 5, the casing 12 is not tubular, and the air from the brake cylinder in an emergency application flows through the aperture 18 in a spring-pressed valve 25. When a service application is being made, air also flows through another aperture 27 in the valve, the spring 26 being sufficiently strong to hold the valve open under these circumstances.
