Title: Improvements in or relating to Variable Speed Driving Gear for Motor Cycles and other Machinery.
Inventor: STUBBS EVERARD
Filed: 1903-12-05
Granted: 1904-04-14
Abstract: 26,635. Stubbs, E. Dec. 5. Motor cycles ; driving - mechanism. -Variable - speed gearing for motor cycles and other machinery is arranged by extending the motor shaft A to receive a toothed pinion A' and providing the end with ratchet-teeth A<2> to form a half-clutch. The bearing B is formed eccentric and carries a circular sleeve C eccentrically drilled so that the eccentricities of the sleeve and bearing when opposed can counterbalance each other or can be arranged to produce an increased eccentricity. The sleeve C supports, by roller bearings E, a driving- ring D, provided with an inner toothed ring D<1> and a half-ratchet clutch D<3> on the cover-plate D<4>. The sleeve C is shifted axially by means of a camgroove and pin, so that, in the concentric position, the clutch parts A<2>, D<3> engage to produce a highspeed gear, and, in the eccentric position, the pinion A' and the toothed ring D<1> engage to produce a low-speed gear. In a middle position, the motor axis is free. Fig. 1 shows the operating- mechanism, in which a lever C' is fixed on the sleeve and connected by a link J to a lever H on the crank axle. The lever H has a double pawl H<1>, one end of which engages in a recess G<1> when the pedal G is turned either way. Tilting-springs K hold the pawl in its tilted position so as to allow further motion of the pedal. A spring stop F is arranged on the motor hub to hold the sleeve in one of the three positions by means of recesses C<3>. L is a lever attached to the exhaust chamber so as to silence the motor when in the free position.

Title: Improvements in Automatic Vacuum Brakes.
Inventor: CHURCHWARD GEORGE JACKSON
Filed: 1904-02-17
Granted: 1905-01-26
Abstract: 3958. Churchward, G. J., Snell, F. W., Rayer, F. H., and Dumas, C. K. Feb. 17. Brakes, vacuum. Relates to valves for automatically regulating the flow of the air into the train-pipe during an ordinary application, other valves for admitting air in emergency applications, and modifications of the driver's valve to adapt it for use with these valves. Fig. 1 shows a regulating- valve, which is connected at b to the driver's valve, and at c to the train-pipe. When the driver admits air to the casing between the diaphragms h, h<1>, it also passes through the pipe k to the underside of the diaphragm h<1>, and more slowly through the constricted aperture l<1> to the chamber i above the diaphragm h, thus closing or tending to close the valve m upon its seat j. When the inflowing air beneath the diaphragm h is exhausted more rapidly than the air above it, the valve m opens again. By moving the driver's valve more than is usual in the ordinary application, an atmospheric port in it admits air through the connection n to the chamber i, thus keeping the valve m open, aid admitting air continuously to the train-pipes, and opening the quickacting emergency valves. In a modification, the valve m and diaphragm h' are replaced by a piston valve h<2>, Fig. 3, and the pipe k is replaced by apertures k<1>, k<2> in the valve. In a modified arrangement shown in Fig. 7, the connection n between the driver's valve and the regulating - valve a is omitted, and the air is admitted to the train-pipe 3 by a valve 12 on a branch 11. The handle 13 may be connected to the handle of the driver's valve 1 so as to lift the valve 12 when the driver's valve is moved into the emergency position. Fig. 8 shows another modification in which the abnormal movement of the driver's valve admits air through the connection 16 to the valve 15 on the branch 11. The air, entering the chamber 15<a>, Fig. 9, of the valve 15, causes the diaphragm 17 to lift the valves 15<b>, 14, and passes into the train-pipes. The air also passes through the small hole 18<a> in the hollow spindle 18 and destroys the vacuum above the diaphragm, so that the valves close again. The air may be pissed directly from the connection 16, Fig. 8, to the train-pipes. Fig. 10 shows an arrangement in which the spring 21 presses the V-shaped stop 20 into a similar recess in the casing of the driver's valve, and prevents the driver from making an emergency application without extra exertion. The diaphragms of the automatic valves may be replaced by pistons.

Title: Improvements in and relating to Calculating Apparatus
Inventor: MUGNIER FRANCOIS
Filed: 1904-05-26
Granted: 1904-07-07
Abstract: 12,021. Mugnier, F. May 30, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Calculating-apparatus.-Relates to a calculating - machine for effecting the four fundamental operations of arithmetic. Two horizontal parallel shafts a, b, Fig. 1, are mounted in the casing s, and upon the power shaft a are mounted a series of gear-wheels r having ten teeth, one of which is larger than the rest. They rotate independently on the shaft but can be made to rotate with the shaft by sliding clutch sleeves n. The latter are driven by the shaft by screw pins t, Figs. 1 and 2, , and carry small pins u which engage one of a series of ten holes in the gear-wheels r when moved by means of the lever f. The teeth of the gearwheels carry the ten numerals, which appear successively opposite windows in the casing e. The shaft a is rotated by the handle m, and the bevelpinion p at the other end of the shaft operates another similar pinion l carrying a circular plate g, upon which are two concentric rows of the ten numerals arranged in opposite order. The support h is inscribed with the first ten letters of the alphabet. The handle m carries a stud which engages one of a series of holes in the fixed crown plate k, Fig. 3, and, each time the handle is oscillated in performing an arithmetical operation, the ratchet-wheel q mounted on the crank of the handle m causes the intermittent rotation of two rollers, the figures on which stop successively opposite the index j and indicate the number of times the handle m has been turned when performing the operation of multiplication. The shaft b also carries a set of cylindrical wheels z, each with ten teeth and operated by the long tooth on each wheel r so as to transmit the amplitude of the tenth of a revolution to the adjacent wheel mounted on the shaft a, the latter then registering the tens which the preceding wheel cannot register. Springs x keep the wheels z in position, bearing against the lower noses of the engaging levers f, and also serve to return these levers to a disengaged position. To perform an addition of numbers, the wheels are all set to zero and the first of the gear-wheels r engaged by the first lever f ; the crank m is then rotated in the positive direction through successive angles corresponding to the unit figure of each number to be added. The second gear-wheel r is then brought into. action and the same operation repeated for the ten's figures of the numbers, and so on. The final result always appears through the openings opposite the gear-wheels in the casing, and the operations for subtraction, multiplication, and division are very similar.

Granted: 1905-07-20
Abstract: 5455. Thompson, W. P., [Ges. f³r drahtlose Telegraphie]. March 15. Wireless telegraphy.-Relates to spark-gaps for use in the oscillation circuits employed in wireless telegraphy. To prevent heating of the metal electrodes, they are formed so that the points which are at the shortest distance apart lie along a circle ; in such a case, the spark does not strike repeatedly on the same point. Several modifications are shown in the Specification, Fig. 4 being a section of one of them showing the ring b of electrodes. Ordinarily, if more than one sparkgap is employed in an oscillation circuit, as in Fig. 5, means, such as inductive resistances, capacities, &c., should be provided to permit the charging potential to be distributed among the gaps in proportion to their widths, these means being practically non-conductors to the rapidly oscillating discharges. The electrodes described possess a considerable area and consequently will of themselves provide these means.
