Title: Improvements in Motor Electric Meters parts of which are applicable to Motors and Dynamos generally.
Filed: 1899-06-30
Granted: 1900-06-30
Abstract: 13,616. E v e r s h e d & Vignoles and Evershed, S. June 30. Energy meters; magnetic measurements.-Motor meters having armatures with commutators are made with large rotary collectors instead of brushes, either the collectors or the commutators being flexible. In one arrangement, Fig. 1, the commutator consists of resilient wires C, of iridium-platinum or other metal, fixed at one end on an insulating-disc on the motor shaft B, and parallel to the shaft. The free ends of the wires bear against gilt or platinized flanges on the edges of the light metal discs E, supported by shafts parallel to the motor shaft ; these shafts turn in metal bearings a, through which the current passes, each shaft having at one end a platinumiridium point and bearing. In a modification, the commutator wires and collector shafts may be radial, or inclined to the motor shaft. The commutator may be rigid, and constructed as described in Specification No. 9127, A.D. 1897, the collectors being cup-shaped. To compensate for residual friction, a small magnet or iron bar is supported so as to provide a small permanent field tending to cause the armature to rotate. The rod may be an extension of a brake magnet. To indicate the strength of the brake magnets, a simple magnetometer is provided. This may consist of an axle carrying a. small strip of iron in the field of each magnet, a counterweight or spring connection, and a long pointer near a fixed scale. The magnets hold up the iron piece in opposition to the weight or spring, so that any change in the strength of the fields of the brake magnets is shown. By slightly weakening and strengthening the brake magnets by means of a shunt piece of iron, or a few turns of a current conductor, the meter can be calibrated and the scale marked for different strengths of the brake magnets, so that a percentage correction may be afterwards applied to the dial readings if the magnets change.

Granted: 1900-05-12
Abstract: 15,705. Barker, J. H., and Ewing, J. A. Aug. 1. Motor meters are provided with demand indicators, by allowing a magnetic or other brake B a small motion in opposition to a strong spring J, and indicating the extent of such motion by a magnifying-pointer L on a stationary scale, either the brake or the pointer L or an additional pointer being provided with a pawl M to engage a stationary rack, by which it may be retained at the maximum indication. A magnetic brake may be added for this purpose to a meter having another fixed brake. The motion of the meter may be either rotatory or oscillatory. The retaining-pawl M may be disengaged from the rack by a lever O, extending through the meter case, and protected by a seal. The pawl may be held out of action by a notched catch N, pivoted on the brake. In the form shown, a rotating disc is acted on by two brake magnets B, secured adjustably by screws, in a slotted yoke C, on an axle parallel to the meter axle. The magnet poles may be arranged astatically, and any effect on the armature balanced by a compensating-magnet or shunt field winding. The brake axle is supported on a ball bearing in a bracket F, is acted on by the spring J, and has a horizontal arm H in engagement with the magnifying- pointer L. To avoid error due to friction, the brake may be caused to oscillate slightly by making one or more holes in the disc. The brake may otherwise be hung by a torsion wire. For travelling, it is secured by screws to lugs C<9> in the frame. A disclaimer refers to Specification No. 8068, A.D. 1896.

Granted: 1900-05-26
Abstract: 2876. Morgan, W. H., and Taylor, A. L. Feb. 13. Cranes.-Relates to foundry cranes specially designed for manipulating forgings. The bridge A and trnlley D are propelled on rails by motors in the usual way. The upper part of the trolley is adapted to rotate on a circular t r a c k, the motion being effected by a pinion. driven by a motor E, which gears with and runs round a circular fixed rack on the lower part of the trolley. A pair of endless lifting-chains are employed, each of which passes around a pair of sprocket-wheels h<7> and h<14> and hangs in two loops. The forging is suspended in a short endless chain N, which passes around a sprocket-wheel driven by spur gearing L<4>, L<5>, from two sprocket-wheels J around which the two lifting-chains pass. Two motors, G<1> and G, are employed. The first G<1>, when in action, drives the sprocket-wheels h<7> and h<14> in opposite directions, so that lifting or lowering is effected. The motor G, when in action, drives the sprocket-wheels h<7> and h<14> in the same direction, so that the forging is rotated upon its axis simply. When both motors are put into action, the two motions take place simultaneously.

Abstract: 14,823. Bert, E. Aug. 18. Regulators and governors. - The supply pipe a, Fig. 1, is connected with an indicator e provided with two movable stops g, h, which are arranged to stand on either side of the needle f, Fig. 2, at the moment when it marks the regulation pressure it is desired to maintain in the apparatus b. Any rise or fall in pressure will then cause the needle to make contact with one of the stops g, h, thereby closing an electric circuit to the electric motor m, which is thereupon set in motion to close or open the valve c as required. The indicator, Figs. 2 and 3,.consists of a needle f on a shaft 16 which carries a pinion 15 gearing with a wheel 14 on a shaft 13. This shaft 13 carries a weight 17, and is provided with an arm 12 connected by an adjustable rod 9 with a diaphragm 6 in the chamber 3 which is connected with the main gas supply. The stops g, h are carried on guide-rings i,j, which are supported on insulated rollers 19, and are connected by springs k to the terminals 21, 22. The electric motor m, Fig. 5, consists of three coils u, mounted on a vertical shaft v revolving above the poles of the permanent magnet x. The shaft v has a worm z which actuates the train of gearing 1, transmitting the movement to the pinion t of the valve c. Spring circuit-breakers 33 are arranged to be lifted by studs 34 on the wheels 1 as soon as the pinion t reaches its extreme positions. The valve c is a spring- pressed disc which opens or closes ports as it is rotated. In modifications, (1), Fig. 8, the rotating spindle s carries a rectangular felt plate 35, and (2), Fig. 10, the rotating spindle s raises and lowers a sliding spring- pressed cylinder 37. A reduction of pressure in any one branch of the apparatus may be effected by means of a screw 38, Fig. 13, which reduces the size of the passage as required.
