Application filed January D, ISSII.
Hy invention relates to improvements in l that class of armatures of dynamo-electric machines in which continuous induced currents ro of electricity are generated by the displacement of magnetism in a cylinder or drum of iron or other magnetic material provided with radial arms and enveloped by inducing-coils of wire or other suitable material. i rIhe object of my invention is to produce a compact armature, whereby two strong continuousy currents are generated which can be used separatelyone for external purposes and one for charging the iield-magnets-and which is simple in construction.
My invention consists of the improvements in the construction of the' armature, which will be hereinafter fully set forth, and pointed out in the claim. a
In the accompanying drawings, Figure l represents a side elevation of my improved armature. Fig. 2 is a cross-section of the same. Fig. 3 is a longitudinal section of the armature. Figs.4 and 5 are perspective views, 3o illustrating the manner in which the coils are wound upon the armature.
Like letters of reference refer to like parts in the several iigures.
A represents the rotating shaft to which the armature is secured, and B represents the cylinder or drum of the armature rigidly secured to the shaft A.
C represents the radial arms of the drum, connected at their inner ends to a hub, d, which is secured to the shaft A. The arms are separated at their outer ends by slots e, formed in the cylindrical outer portion of the drum B, midway between each pair of arms, whereby each arm C is provided at its outer 4 5 end with a head or polar enlargement, C', having the form of a cylinder-segment.
j' represents coils or helices of copper wire, or other suitable material, wound upon the webs or radial portions of the arms G, the sev (No model.)
eral coils being wound in the same direction upon the several arms. The issuing'end of one coil is connected to the entering end of the next adjacent coil, and both are connected to the same commutator section as represented in Fig. 4, thereby forming a closed cir- 5 cuit. By revolving this armature-between the north and south poles of a magnet two currents are produced in the coils of the armaiure, the currents issuing in opposite directions in the two halves of the armature opposite the two poles of the magnet. These currents can be collected by brushes applied to opposite sections of the comniutator midway between the poles of the magnet. The current so generated can be used for various purposes 5 65 but I prefer to employ it for charging the held-magnets.
h represents coils of wire or other good conductor wound upon the cylinder B. Each of the heads or poles C is covered by two coils 7o arranged side by side, so that the number of external coils, 7L, wound upon the cylinder is equal to the number of internal coils, f,wound upon the arms O, eight internal and eight eX- ternal coils being employed inthe construction represented in the drawings. Each of the coils h is wound lengthwise over the outer side of the cylinder, then across one end of the cylinder, then back along the opposite side of the cylinder, and then across the op- 8o posite end of the cylinder to the starting-point. The issuing end of one coil is connected to the entering end of the next adjacent coil, and
l the two ends are connected to the same coinmutatorsection as represented in Fig. 5, thereby forming a closed circuit.
I represents the commutator with which the internal coils/", are connected, and J the commutator with which the external coils, h, are connected. By the rotation oi' the armature 9o between the poles of a magnet currents are produced in these external coils in the same manner as in the internal coils, and the currents produced in the external coils can be collectedby brushes, as before stated, and be employed for lighting, plating, or other purposes independently ofthe currents generated in the internal coils, thereby avoiding the reinner ende 11nd having their ontel ends 1110-- vided with seperate 'polar extensiene` C, olf
