Title: Improvements relating to the Compression of Air and Utilization of the same for Motive Purposes and to Apparatus therefor.
Inventor: PETTEE EDWARD EVERETT
Filed: 1899-10-07
Granted: 1899-11-11
Abstract: 20,176. Pettee, E. E., and McCutchan, J. J. March 9, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Motor road vehicles.-An explosion engine E drives an air-compressor A, which supplies compressed-air engines f directly or through a reservoir M'. The air, before it enters the compressor, passes over the water in the tank M from the explosion-motor cylinder jacket, and becomes moistened and heated, and the exhaust from the explosion motor passes through jackets around the supply and exhaust pipes and the cylinder of the compressed-air engines f. Fig. 1 shows the parts arranged on a front-steering rear-driven road vehicle, the wheels a being loose on their axles and driven by gearing c. Fuel is supplied to the motor A from the tank L. The motor and the compressor are shown in section in Fig. 3. The motor and compressor pistons are connected to opposite cranks, and the valves r, z and igniter v are operated by cams i, k, and j.

Title: Improvements in Controllers for Electric Motors.
Inventor: DAVIS HARRY PHILLIPS
Filed: 1899-10-21
Granted: 1900-09-15
Abstract: 21,083. Davis, H. P., and Wright, G. March 24, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Switches.-Consists of apparatus which operates with a predetermined rapidity, which is independent of the character of the impulse imparted by the operator. Upon a base 1 are mounted contactpieces 14 constituting the stationary terminals for the electric circuits and adapted to engage contactpieces 13 mounted upon a non-conducting drum 111, which is rotatable for effecting the circuit changes necessary for the control of the motor. This drum is provided with metallic ends 12 and 121 mounted upon loose sleeves 7 and 9, which are also loosely mounted upon the shaft 3 and are connected by a spiral spring 8. At one end of the shaft 3 is fixed a collar 4, which carries the operating hand-wheel or the like, not here shown, and two arms 5 with projections 51 for engaging the standards 2 and thereby limiting the rotation of the shaft 3. In operation, the controllor being in the zero or " off " position, when the shaft 3 is rotated in, say, the clockwise direction, an arm 62, Fig. 4, of a cam 6 fixed to the shaft 3 engages a lug 72 on the sleeve 7 and, the other sleeve 9 being retained by the drum, winds up the spring 8. The arm 61 of the cam 6 then moves a roller 17 on a spring-pressed pawl 16 out of engagement with a notch 151 in the drum end 12 and liberates the drum, which thereupon turns at a definite speed determined by the strength of the spring and the adjustment of a dash-pot 28, Fig. 2, operated by levers 21, 23, 24, and 20 and a cam 19 on the other end of the shaft 3. The contacts 13 and 14 corresponding to the initial speed of the motor are thereby quickly engaged, and the further movement of the drum to engage the contact-pieces corresponding to the maximum speed of the motor is then slowly effected at a speed controlled by the dash-pot mechanism. The shaft 3, sleeves 7 and 9, and drum end are fitted with suitable lugs for effecting the above-described operations in the opposite direction. For direct currents, a modified arrangement is described in which the drum end 12 is provided with two retaining-notches, in order that the drum may be stopped at such a position as to avoid short-circuiting the motor armature when thrown from either "on" position to the " off " position.

Granted: 1901-01-12
Abstract: 2004. Lane, F. L. Jan. 31. Brakes, hand. Relates to brakes which can be applied from either side of a wagon. The ordinary brake lever f is connected by the link e to the short lever d formed on one end of the rotatable cross-shaft c, which has a similar short lever at its other end. When either of the levers d is depressed, the lever f is lifted and the brakes are applied, and at ihe same time the pawl m on the shaft l drops into the ratchet sector k mounted on the lever d. The brakes are released by operating one of the handles n at the end of the shaft l to lift the pawl m, and thus allow the lever f to fall. Modifications are described in which the brakes can be worked from the diagonally - opposite corners or from the centre of the sides of the wagon. The Provisional Specification states that the pawl m may be arranged to lock the brakes in the "on" or "off" positions.

Title: Improvements in Guillotines or Machines for Cutting Paper or other Material
Inventor: JAMIESON JOHN
Filed: 1900-12-11
Granted: 1902-01-02
Abstract: 22,531. Jamieson, J. Dec. 11. Cutting-machines for paper &c.-Relates to improvements on the inventions described in Specifications No. 2362, A.D. 1881, and No. 12,196, A.D. 1900, and to means for automatically connecting the counterweighted shaft Q of the clamping-bar and the weighted lever K when the machine is started, and disconnecting them when the cut has been made. The lever K is connected by a link L with a lever H, which is screwed on to the shaft Q and has one side of its boss made wedge-shaped. Between the boss of the lever H and the boss of the lever H<1>, which is fast on the shaft Q and is connected with the clamp, is a loose lever having a wedge-shaped boss N, which is connected by a link G and lever I with a spring V. The shaft of the lever I carries also a lever F, on which the trigger A is pivoted and which takes into a notch in the starting-lever B. The clamp is brought down to the work by means of a treadle, and the machine is started by releasing the trigger A from the stud M on the bell-crank lever X connected with the knife-bar. The release of the trigger A allows the spring V to rotate the wedge-shaped boss N, so that it fills up the space between the bosses of the levers H, H<1>, and the movement of the lever H owing to the descent of the lever K causes the rotation of the shaft Q and the further descent of the clamping-bar. When the end has been completed, the stud M on the lever X engages with the trigger A, causing the stoppage of the machine and the rotation of the wedge-shaped boss N, whereby the levers H, H<1> are released from one another and the clamp is free to be raised by its counterweight.

Title: Improvements in Electric Furnaces and in the Production of Chemicals in such Furnaces.
Inventor: BREWER GRIFFITH
Filed: 1901-12-10
Granted: 1902-01-23
Abstract: 25,182. Brewer, G., [Taylor, E. R.]. Dec. 10. Electric furnaces.-A furnace applicable for arc or resistance heating, or for electrolysis, is constructed as shown in vertical section. It may be used for making chemicals, such as carbon. bisulphide, the vapour of which is delivered from the top of the furnace to a condenser. It consists of a metal casing, lined with asbestos or other insulating-material, surrounding an inner wall 4 and partitions s, between which are spaces through which a fusible material such as sulphur is fed from hoppers p, q, so that, when fused, it enters the central space through openings v. Infusible material, such as charcoal, is charged into the furnace, to fill it nearly to the top of the inner wall 4. Four electrodes 5 are supported in passages in the furnace walls. These passages are closed by metal doors, which are packed and insulated by asbestos placed between the doors and strengthening-frames surrounding the openings in the casing. Conducting-stems attached to the electrodes are covered with mica and asbestos insulation, and pass through packed boxes in the doors ; they are cooled by sulphur or other fusible material, fed from hoppers through vertical channels behind the electrodes. Broken coke or other conductive material is fed through vertical tubes and openings l over the inner ends of the electrodes, to protect these and form conductive paths between them. In order to remove pillars which may form in the furnace, the direction of the current supplied to two adjacent electrodes is changed by a switch periodically or when necessary, so that currents pass across the furnace either between opposite electrodes or between adjacent ones. The current is controlled by rise of the fused sulphur or other non-conducting fusible material between the electrodes, and by varying the supply of broken coke. Fused material may be run off through a passage z<1>, covered with loosebricks.
