Title: Improved Acetylene Gas Generator
Inventor: LEPINE CELESTE DIEUDONNE
IPC: C10H9/00
Filed: 1901-10-10
Granted: 1902-02-13
Abstract: 20,282. LÚpine, C. D. Oct. 10. Acetylene.-Relates to apparatus in which the supply of water to the carbide is automatically controlled by the pressure of the gas, and has for its object the use of hydraulic seals or joints in place of taps for the communication between the generator and the gas holder. The generator, which is not shown, is mounted on one side of the outer casing 2, and water is supplied to it from a tank 6 by a pipe 8, a pressure-regulating tank 9, and a pipe 10 which rises nearly to the height of the top of the generator, where it divides into.two branches, one of which leads into the generator. The other branch, after rising above the level of the top of the pipe 8, descends again to a tank 13, containing purifying-liquor, into which it delivers the gas from the generator. The gas passes thence by the pipe 14, cooling and condensing worm 15, and pipe 16 into a gas holder 1, which communicates at the bottom with the outer tank 2. A safety-escape pipe 38 is fitted neir the bottom of the gas holder. The water in the gas holder is more or less expelled by the gas into the outer tank, and the head thus produced determines whether the water in the pipe 10 may rise to the generator inlet or not. The tank 6 is intermittently supplied with water from a surrounding tank 5, with which it communicates by an opening 17 and a pipe 36, the flow being interrupted whenever the water rises in the tank 6 above the lower end of the pipe 36 and cuts off the access of air to the tank 5. When the apparatus is not in use, the valve 6, which is shown supported by a ring 20 resting on two blocks 22, 23, is lowered upon the entrance to the pipe 8. The generator, which is provided with a cover at the top secured by a stirrup and screw, is charged with a number of superposed carbide holders, each divided into four compartments, which are notched at the top to different levels, so that the water may overflow into them in succession as it rises in the generator.

Title: Improvements in Pulp Compression Apparatus
Inventor: SHAW GEORGE EDWIN
Filed: 1902-02-18
Granted: 1902-06-05
Abstract: 4101. Shaw, G. E. Feb. 18. Moulding pulp.-Fig. 1 shows, in sectional eleva- tion, the apparatus for manufacturing articles from pulp material of any desired form or shape and of uniform density. As illustrated, the press is adapted for the construction of buckets or kegs. A supply of pulp is admitted below the piston D by the aperture C', whence it flows into the com- partment c' formed by inwardly-moving blocks C. The middle of this compartment is taken up by the hollow core a, which is rigidly attached to the table G, supported by the piston-rod H. The out- side covering of the core consists preferably of three parts suitably secured together, e.g. by means of the flange a<5> and T-shaped notches engaging with the T-shaped lugs on the core covering. On a descent of the spider E, and the piston, the blocks C are simultaneously protruded towards the core a, compressing the pulp before them. For drainage purposes, the groove d is provided in the piston, whence the liquid escapes above the piston. Also, when the port d<1> is passed by the piston, the port is opened through the action of a rod e' on an arm d<4>, and the liquid allowed to pass through the port. The port is normally closed by a plug which carries a spring arm engaging with the bell-crank lever e<3>, the other arm of which intermittently engages with the rod e'. The action is such that, on the descent of the spider, the spring arm d<4> is released, and the plug closing the port withdrawn. Upon the upward movement of the rod e<4>, a pin engages the bell-crank lever and closes the port. After the pulp has been compressed to the form of the keg B, the pressure is relieved. Props g are swung back and the table G is lowered until the annular receiving-table g<5> strips the core-covering and the keg from the core. The covering, which is now the keg lining, is removed by removing one of the parts of which it is constructed.

Title: Improvements in Reversing Valve Gear.
Inventor: BROWN ANDREW BETTS
Filed: 1903-02-18
Granted: 1904-01-14
Abstract: 3799. Brown, A. B. Feb. 18. Steering - gear. - Relates to reversing steam steering-engines. Steam is admitted to the cylinders 51, 52 through ports 47, 48, 49, and 50, the openings in the valve-chest 43, 44, 45, and 46 being governed by the annular valve 17, kept on its seat by the spring 19, and operated by a cam or eccentric 20 on the shaft 30. The shaft has at its lower end a helix 31 gearing with a nut 32 on the bevel-wheel 42, which drives the shaft 30 through the bevel-wheel 41. To reverse the engine, steam is admitted to the cylinder 54, and acts on the piston 53, causing the shaft 30 to move longitudinally and alter the position of the valve. Steam exhausts from the cylinders 51, 52 into the interior of the valve 17, and through ports 28, into the passage 70. A cataract cylinder is connected to the framing as shown in Fig. 2. Steam is admitted to, and exhausted from, the cylinder 54, by either of the pipes 55 or 56, the supply being regulated by the valve 57, Fig. 5, on the spindle 63, worked by a telemotor lever or by hand. Steam enters the valve casing 58 through the pipe 59, and exhausts through the pipe 60. As the spindle 63 turns, inclined faces 64 attached to the spindle raise an annular disc 65 having corresponding faces, and opens the valve 66, which admits steam from the steam pipe 67 to the engine cylinder 18, through the pipe 68. Exhaust steam from the port 70 escapes by the pipes 71, 73. The valve 69 opens in advance and reduces the pressure on the back of the valve 66. When the engine is used for steering purposes as described in Specifications No. 4826, A.D. 1900, and No. 11,183, A.D. 1901, the steam and exhaust pipes 67, 73 are carried in trunnion bearings 23, the arrangement shown in Fig. 5 being carried on the tiller. When used for stationary purposes, the lever 76 may be actuated by a floating lever device. Modifications may be used, in which the position of the cam 20 operating the admission valve is reversed by steam acting on the fixed blade 80, the steam being admitted and exhausting through passages 81 or 82 as shown in Fig. 4. The helix on the end of the shaft may also be dispensed with and replaced by a jaw-chuck remaining locked when running in either direction, and operated by a hand-wheel.

Inventor: MASCORD GEORGE WILLIAM
Filed: 1904-01-11
Granted: 1905-03-11
Abstract: 727. Mascord, G. W. Jan. 11. Driving machines by electromotors.- Relates to gearing machines, such as printing-machines, in which a heavy starting-torque is required, with electric motors in such a manner as to start the machine at a low speed, the motor rotating the while without load or underlight load, and then coupling it directly to the motor. The motor shaft a, Fig. 1, is placed in line with the machine shaft i and provided with a friction clutch b for the purpose of connecting or disconnecting the two shafts. The shaft a is also connected with the shaft c by speed-reducing gear, which may consist of bevel pinions, a worm b<3>, and worm-wheel b<4>, which is loosely mounted on the slow-motion shaft c. The wheel b' is provided with a number of spring pawls b<5>, which engage with a boss b<6> fixed to the shaft c. The worm b<3> may be driven by an auxiliary motor f, Fig. 3. When the pivoted operating handle g is moved from the position x, a suitable tripping-device releases the bell-crank lever n', which under the action of the weights n and through the link n' and bell-crank lever n disengages the boss d<2>, which is keyed to the shaft c, from the clutch d<1>, the pinion k to which the part d' is fixed riding loose upon the shaft c. The clutch b is also operated by the handle g through the connecting-mechanism o, o<1>, &c., being fully engaged when the handle reaches the position y, and the speed-reducing gear being disconnected. The gear-wheel j<2>, which transmits motion to the press mechanism &c., is now connected through the gear-wheels jl, j to the motor m. Further movement of the handlever g switches in resistance into the field of the motor, thereby increasing its speed. The handlever g may be operated through the toothed gearing g<3> by the movement of the piston h in the cylinder h', under the pressure of compressed air which may be admitted from a reservoir h<4> through a three-way valve h' and stop valve h<4>. The pressure of the air in the reservoir is maintained constant by means of a pump h<5> driven by an eccentric h<6> on the shaft a. Fig. 2 shows a modified form of the operating-mechanism, pressure being transmitted to the cylinders h<11> through the valves t, t<1> under the control of the lever, u, t<2> being exhaust pipes and t<3> supply pipes. The controlling-mechanism of a second press &c. may be operated by a rod e connected to the lower end of the hand-lever g.
