OERLlKON, OF OERLlKON,
DYNAMG AND MGTQFL SPECIFICATIQN forming part of Letters Patent No. 386.685, dated July 2%, 1888.
Application filed November 9, 1886. Serial No. 218.396. (X0 model.)
To (tZZ whom, it may concern:
Be it known that 1, CHARLES EUGEN LAN- CELOT BROWN, a citizen of England, residing at Zurich, in the canton of Zurich, Switzerland, have invented certain new and useful Improvements in Electric Generators and Mo tors; and .i do hereby declare the following to he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same, reference being had to the as companying drawings, and to letters or figures ot'rei'erence marked thereon, which form a part of this specification.
This new construction is shown by the an neXed drawings, in which Figure 1. represents the plan, Fig. 2 the ver tical longitudinal section. Fig. 3 the front view, Fig. an end view, and Fig. 5 a see tional end view.
The dynamo is built in the following way: The polepiecc K, with the lateral adio'ined pieces, directly forming the framing B, the supports of the bearings C O, and the nipples B for the fastening oi' the machine, are comprised in one single piece of casiin The cores of the magnets are incased in the polepiece K and i'asteiiicd with the screws a a. The heads 01' the cores hear the pole-piece L, to which they can be fastened in the same way as in the lower pole-piece, or the polepiece sits Hat on the cores and fastened by the screws 0 I), as shown in Fig. L3.
For lifting oil the pole-piece L and to l'acili tate the conveyance of the machine the polepiece L is provided with an iron bow, M, placed in it while it is cast.
In order to facilitate the winding of the coils A A, the exciting-wire is coiled upon a cylindrical casing made of metal or an insulating material, and the whole slid over the magnetic cores. The flanges retaining the coils are made of wood or vulcanized or other iiher. The cap-pieces ofthe plumbecblocks G O are at the same time the greaseehambers, containing both a liquid and a solid lubricant. The axle-bearings are so disposed that the dropping oil will be collected and led into the dripchambers D D in the bearing-supports C C, whereirom it tau be let oil by a cock placed at p p.
The bearing on the side of the collector Jis provided with a groove, a, serving as guide to the brush-bridge E. This consists of a collar made of two parts, 0 c, which are held together by the screws (2 (2. By this means the brush-bridge can be turned, but not movable in the direction of the axis.
On the arms ol'the bridge, insulated plates 0 c are screwed, in which bear the spindles for the brush-holders and connectors for the current'condactors.
F refers to the steel armature-shaft; H, the armatureiron to hold the coils and plates; J, the collector or commutator, and G the driw ing-pulley.
l The armature-iron is formed of thin insul lated rin s made of charcoal- )lates. Thev are kept together and made fast to the shalt by the bronze wheel N, and have grooves cor responding to the arms 01' the wheel to prevent their twisting. They are compressed by the bronze plates g g, the ribs h of which fit into corresponding grooves in the wheel.
The disks or rings f are perforated with holcsf near their periphery, as shown in Fig. it, in which holes the insulated copper wires 7;, exposed to the inducing action, are pushed. By this device the resistance which the magnetism has to overcome in passing from the magnets to the armature is reduced toa minimum, and obviates the necessity for fastening of the wires of the armature to protect them against the effect of the centrifugal force. The single horseshoe-shaped wires are pushed into the ring from the side of the pulley. The projecting extremities on the other side are connected by the lainels '13 to the collector J. and with themselves to a closed circuit similar to the Pacinotti-Graninie ring arrangement.
The composition of the collector is visible in the drawings. The single lamels'iare made of phosphor-bronze. The insulation of the single parts is prod need by mica or asbestos.
The spokes ot' the pulley are shaped like the vanes of a ventilator. The air, according to the position of the vanes, is sucked through the pulley and expelled through the apertures mm, or sucked through these latter and expelled through the pulley. To increase the ventilation, interstices y may be left'open in the iron of the armature.
The pulley and collector can either be keyed directly on the shaft,or the nave of the bronze wheel may be lengthened and the above parts fastened to these projections. Fig. 2 represents the collector keyed directly to the shaft, while the pulley is fastened to the prolongated nave of the bronze wheel.
I claim in electric generators and motors- 1. The combination, with the brush-bridge E, comprising the two parts 0 c and screws d d, of the grooved bearing n, for said brushbridge, and the insulated plate 6 e, in the ends of which bear the spindles for the brush-holders and connectors for the current-conductors, substantially as set forth.
2. The hereindescribed armature, comprising the wheel N, the compressing-plates g 9, having ribs fitting grooves of said wheel, and the insulated rings f, held together by said wheel, substantially as set forth.
3. The combination, with the shaft F and the collector J of the wheel N, the plates 9 g, the insulated rings f, the horseshoe-shaped wires k, and the lainels 13, substantially as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
I CHARLES EUGEN LANOELOT BROWN. lVitnesses:
