Inventor: PENDOCK CHARLES ROBERT
Filed: 1904-01-25
Granted: 1904-12-31
Abstract: 1834. Pendock, C. R., and Edwarda, S. Jan. 25. Lifts.-Relates to safety interlock ing apparatus between the well doors and cages of hoists, lifts, or elevators, and consists of a shutter in the cage adapted to cover the handing rope, and thus prevent movement of the cage without affecting the mechanical freedom of the cage or handing rope, the shutter being so connected with a special well-door lock that the handing rope cannot be uncovered till the well door opposite the cage is locked, nor the door opened until the rope is covered. Fig. 7 shows a plan of the apparatus where double hinged well doors are used. The shutter b, adapted to cover the handing rope c, is pivoted at b<1>, and is connected by a crank and connecting-rod b<7> with a frame d slidably mounted on the front of the cage. In the face of the frame d is a vertical channel flared at the top and bottom, and capable of engaging a roller k<5> carried by an interlocking bolt k mounted in a box i on some part of the door frame. Mounted on vertical pins in the box i are catch plates j, j<1>, having notches to engage vertical studs g' on the doors and quadrantal extensions j<6> to co-act with extensions k<1> of the bolt k. When the door is open, as shown, the parts j<6> lock the bolt k in a position to hold the shutter b over the handing rope, while, when the door is locked, the front faces of the extensions k<1> engage the radial faces of the extensions j<6>, so that, while the bolt k is free to allow the opening of the shutter, it at the same time holds the catches j, j<1> in their locked position. The invention is also shown applied to single hinged, and to horizontally and vertically sliding, doors, the catches j in the last case being vertical and the bolts h being replaced by oscillating arms.

Abstract: 4687. Perrier, O. Feb. 25, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Distilling spirits.-Distilling-apparatus of usual construction is provided with appliances for regulating the pressure and temperature, and with two pieces of apparatus respectively called a "bead wine-heater "analyser," for use in obtaining spirit of high degree, and a "homo- "therm molecular "analyser" for use when it is desired to obtain spirit of any fixed strength. Fig. 1 shows the application to apparatus of the Champonnois type. The pressure regulator consists of a reservoir P, connected to the column A. and containing a float p which actuates a lever l, l<1> carrying rods a, a<1> bearing adjustable slides c, c<1>, arranged to open and close valves v, v<1> on the steam and exhaust pipes. The temperature regulator consists of a cylinder T, in which the current of vapour circulates about a tubular member containing water, and a closed air chamber ; the variations of tension are transmitted to the mercury cup z and cause the float f to rise or fall actuating the lever g and the valve w, which controls the supply of liquid to be distilled. The "bead wine-heater analyser" consists of a vessel E, containing a number of tubes e filled with beads and surrounded by the liquid to be distilled. The wine is introduced through a perforated coil at the upper part of the heater E, or a baffle cylinder is used which confines the liquid to the annular space between the two cylinders. The liquid from the refrigerator R is distributed, as required, by means of the cock r. The "homotherm molecular analyser "consists of a cylinder provided with internal baffle-rings and charged with beads. When used, it is connected to the column B, the refrigerator R, and to a condenser placed above it. The vapours which pass through it are maintained at a constant temperature, predetermined by the boiling point of the liquid which it contains. Fig. 3 shows an arrangement of plant, including apparatus for the concentration of the fractional products. The column B is provided with low-temperature distillation plates C, a tubular heat-exchanger N, a washer D, and an analyser I for eliminating the aldehydes. The ethereal products volatilized in the exchanger N and retrograded by the analyser I are conducted through the pipe 36 to the refrigerator R. The products less volatile than alcohol are separated in the analyser F, which is supplied with the retrogradations from the rectifier G, and are transmitted to the exhaust column H. The concentration column M is surmounted by a "homo- "therm analyser " L connected to a wine-heater V. The temperature regulator T' actuates the supply valve w<1>.

Abstract: 12,255. Goode, E. J., and Wells, F. B. May 30. Drain ploughs and trench excavators.-A machine for cutting trenches for drain pipes &c. consists essentially of a main frame carried by two pairs of wheels and a pivoted extension frame carrying special apparatus for cutting and raising the soil, and is provided with means for lifting the coulter &c. out of work and for steering both pairs of wheels separately. Fig. 1 is a side view showing the coulter in its working-position and Fig. 5 is a partial plan showing the steering-mechanism for the hind wheels when the coulter is raised. The coulter D is U-shaped and is fitted with a curved delivery trough E, which is made reversible so that soil may be delivered at either side of the ditch. The bottom of the ditch is cut by a pivoted shoe e provided with a screw adjuster g. The coulter &c. is raised by rotating a shaft h by means of a hand-wheel k<1> and suitable gearing. The shaft h is mounted in brackets b on the pivoted extension frame A<1>, and carries sprocket-wheels h' which wind themselves along chains i. The movement of the brackets b causes the rear part of the main frame A to rise relatively to the wheels C, which are free to move vertically while the machine is at work. The wheels C are carried by spindles l<1> rotatable in sockets l<2> keyed to a shaft m, which is rotatably mounted in the brackets b. The rotation of the shaft h winds up a second chain connected with the shaft m, and thus causes the sockets l<2> to assume a vertical position when the coulter is raised for transport or backing purposes. The wheels C are steered by means of a handwheel q<2>, on a shaft q<1> connected by bevel-gearing with a worm spindle q, Fig. 5. This worm gears with rack teeth on a slide o, which is connected with the wheel spindles l<1> by a rod p and levers p<1>. The guide-plate n is mounted on the shaft m and is connected with the socket q<3> for the shaft q<1>. Suitable gearing, such as that shown in Fig. 1, is used for steering the front wheels B. A catch t is provided to lock the extension frame A' in position while at work. The machine is hauled by means of a wire cable passing round the pulley F.

Granted: 1904-10-20
Abstract: 17,600. Baumer, M. Aug. 12. Relays; telegraphs.-Relates to a relay for use in electric feed-mechanisms, printing-telegraphs, &c. by which currents of one sign, on one line, are used to close the operating-circuit and the readjustment circuit as may be required. The pivoted armature 4 closes the operating-contact 9 with every impulse sent through the electromagnet 1, but the pivoted lever 5, resting on one end of the lever 4 and retarded by an air brake, falls so slowly that it closes the re-adjustment contact 8 only when the armature 4 is attracted for a sufficiently long period. With currents of comparatively short duration, the lever 4 rises and lifts the lever 5 up again before the latter closes the contact 8. Adjustment can be effected by varying the position of the lever 5 and by the counterweights 12, 13.

Granted: 1905-08-31
Abstract: 23,348. Greig, D., Chandler, S., and Chandler, J. Oct. 29. Lighting and extinguishing gas.-The supply of gas to a set of lamps is automatically turned on and off by a temporary increase of pressure. The apparatus consists of a gasometer D and a drum valve H, to which gas is supplied by tubes V, K, rising above the level M of the liquid. An increase of pressure raises the gasometer D, which is provided with pivoted levers P abutting against stops S ; these levers, engaging with pins J on the drum H, revolve it half a revolution, thereby opening communication by a passage L between the gas-supply tube K and the orifice T to which the lamps are connected. When the temporary increase of pressure is removed, the gasometer will subside, the levers P rotating to pass clear of the pins J of the drum H, which is prevented from moving backwards by a ratchet-and-pawl device W on its spindle. The apparatus will then be ready for another temporary increase of pressure, when it will close the drum valve H.

Title: Improvements in connection with the Control of the Electric Circuits in Systems of Electric Traction.
Inventor: RAWORTH ALFRED
Filed: 1906-01-24
Granted: 1906-05-03
Abstract: 1830. Raworth. A. Jan. 24. Electric railways and tramways.-In systems of electric traction with regenerative motor control, when the circuit-breaker in series with the motors on one car is caused to open by overload &c., the circuit remains closed through a resistance in parallel with the circuit-breaker so that the motors cannot receive or deliver an excessive current. The main generator 1 supplies current through the main overload cut-out 2 and through the return current cut-out 11, the terminals of which are short-circuited by a resistance, to the positive busbar 3, which supplies current through the feeders 4, 5, 6, containing the cut-outs 8, 9, 10 shortcircuite by resistances 8<a>, 9<a>, 10<a>, to the sections of the trolly 7. The various resistances that shortcircuit the cut-outs are of such size that, when the cut-out is open, no excessive current is allowed to pass through that part of the system in which the circuit-breaker is placed. By this means, the lamps upon the car and the main generator are preserved from damage resulting from excessive regenerative current. It may be arranged that the shortcircuiting resistance is cut out of circuit when the cut-out is closed.
