Granted: 1899-04-08
Abstract: 4666. Lees & Co., A., and Bardsley, C. E. March 3. Carding-engines.-Relates to means for driving the doffer at two different speeds. The gearing is carried by the pivoted lever 6, the wheel 5 on the doffer shaft being driven by a pinion 16 on the boss of a spur-wheel 15, which may be driven at two different speeds from two adjacent pulleys driven by the belt 11. One of the pulleys is connected with the wheel 15 by a pinion 17, and the other one is connected with it through the pinions 12, 13, 14, of which 14 is made wider than the others, so that it will properly engage with the wheels 13, 15. The belt 11 is normally held on the fast-driving pulley by means of a system of weighted levers provided with a treadle, and, when it is desired that the doffer shall be driven at the slow speed, the strap is transferred on to the adjacent pulley by depressing the treadle, which is retained in the depressed position by a weighted catch.

Title: Improvements in Controlling Apparatus suitable for Use with Electric Motors.
Inventor: WALKER HENRY JOHN
Filed: 1899-06-07
Granted: 1899-08-19
Abstract: 11,885. Walker, H. J. June 7. Switches.-A controlling-apparatus for electric motors is so constructed that, on a reduction in the speed and back electromotive force of the motor, due to an excessive load, an additional resistance will be automatically thrown into circuit and thus prevent injury to the motor armature. Fig. 3 shows an elevation of the controller, and Fig. 7 a diagram of the contacts and connections. There are two series of resistance contacts 2 and 2<a>, so that the motor may be driven in either direction, a pair of arc-shaped contact-plates 8, a contact-ring 7 recessed at 7<a>, and an inner ring 6. Over these move a pair of contact-arms 14 and 15, mounted on a shaft 13, which is operated from a concentric hollow shaft 16, Fig. 3, by means of a pair of reversely-set ratchet-wheels 17 and 17<a> and pawls 19 and 19<a>, either of which can be disengaged by a solenoid 21 or 21<a> arranged in a shunt circuit. Should the back electromotive force of the motor fall below a predetermined amount, the solenoid 21 or 21<a> will disengage its pawl, and one of a pair of springs, connected to a lever 26 on the shaft 13, will return the contactarms and increase the resistance in circuit. When a sufficient resistance has been thrown in, the solenoid is disconnected by a movable contactpiece 33 or 33<a>, Fig. 7, coming over the recessed part 7<a> of the contact-ring 7, and the ratchet gear is once more thrown into engagement. A blowout magnet 34 is arranged in the same circuit with the solenoids 21 and 21<a>, so as to prevent sparking when the contact-arms pass to the off position.
Patent GB-189913026-A (GB)
Title: Improvements in Apparatus for Opening and Closing Bulkhead-doors, Ports, Valves, Gates and other Reciprocating Devices.
Inventor: JUSTICE PHILIP MIDDLETON
Filed: 1899-06-22
Granted: 1899-08-19
Abstract: 13,026. Justice, P. M., [Long-arm System Co.]. June 22. Lifts.-Relates to improvements on the apparatus described in Specifications No. 16,013, A.D. 1896, [Abridgment Class Hinges &c.], and No. 18,248, A.D. 1897, [Abridgment Class Hinges &c.]. It is shown as applied to the opening and closing of ships' bulkhead-doors, but may also be employed to close the hatches and elevator doors in warehouses. The door B, Fig. 4, carries a cylinder B<1> moving on a hollow rod A<3> secured to the bulkhead. A pipe A' passing through this rod supplies fluid under pressure to the lower end of the cylinder, while the annular space between the pipes and the rod serves as a supply and exhaust passage for the upper end of the cylinder. The opening and closing of the door is controlled by a valve arrangement D. The valve casing is divided into two chambers, to one of which, as shown in Fig. 8, the fluid under pressure is led by a pipe E. The other communicates through a pipe H with the reservoir H'. Fig. 4. In the pressure chamber shown there are two valves; one K<7> controls the admission to the pipe C' leading to the upper end of the cylinder, and the other K<6> controls the admission to the pipe C and the lower end of the cylinder. Two valves in the exhaust compartment similarly control the exhaust from the cylinder. The valves are controlled by a spindle. M on which is a hand-lever M', Fig. 4. A second lever N' on the other side of the bulkhead is connected to the lever M' by bevel gear. The springs are adjusted to hold the valves closed against the ordinary working pressure. By considerably increasing this pressure, however, all the doors can be simultaneously closed, the pressure being then sufficient to raise the valve K<6>. Any door can at any time be opened by hand, and is automatically closed when the hand-lever is released. In event of any breakdown in the pressure-generating gear, the door can be opened or closed by means of a handpump T, Fig. 4, actuated by a lever T' which is placed in the slot t. As shown in Fig. 1, the pressure in the system is maintained by a steam or other fluid-pressure accumulator, in which F' shows the steam cylinder and F' the ram cylinder. Steam is supplied to the cylinder F<1> through two reducing-valves p, p<1>, and thence to the pump cylinder I<2> by the pipe P<1>. When the pressure in the mains is to be increased to close all the doors on an emergency, the valve R' is opened to admit fluid under pressure from the pipe E to a spring-pressed piston in the cylinder Q. This piston is thus moved to open the valve p<5>, and admit steam from between the two reducing-valves to the pump I<2>. In a modification, compressed air is used in the normal working of the system, while each door can be opened or closed, by hand, by means of a liquid supplied by a hand-pump. The liquid reservoir is provided with special means for separating and releasing the air which enters it with the exhaust water.

Granted: 1900-01-27
Abstract: 21,654. British Thomson-Houston Co., [Case, F. E.]. Oct. 30. Electric locomotives and motor vehicles. - Relates to the braking of electrically-propelled vehicles. The method consists generally in supplying the brake shoes from an auxiliary source of electromotive force (preferably a storage battery, though the linewire may be used), and using the motors also to effect a retardation of the car. The two actions supplement each other, and are arranged to give a practically constant result. The motors may supply part of the current for the brake shoes, and may regulate the braking. In Fig. 2, the motors M<1>, M<2> run as generators, and, as their current diminishes, the solenoid switch S cuts out resistances R<1> in the circuit of the brake shoes BS', BS<2> and battery B. In Fig. 3, the brake shoes and battery B are in parallel with each other, and in series with a resistance R in the circuit of the motors when they are running as generators, so that the battery is first charged and then supplies current to the brakes. The driver's controller, including the usual series-parallel and reversing switches K, RS and a special brake switch BK for producing the conjunction shown in the lastdescribed modification, is shown in Fig. 6. Two other modifications, with varying arrangements of the fields, armatures, &c., are also described.
