W. HOOHHAUSEN. Dynamo-Electric Machines.
No. 224,593. P atent'ed Feb. 17, 1880.
UNITED STATES PATENT OFFICE.
WILLIAM HOOHHAUSEN, OF NEW YORK, N. Y.
DYNAMO-ELECTRIC MACHINE.
SPECIFICATION forming part of Letters Patent No. 224,593, dated February 17, 1880.
Application filed November 1, 1879.
To all whom it may concern Be itknown that I, WILLIAM HOCHHAUSEN, of the city of New York, in the county of New York and State of New York, have invented a new and useful Improvement in Dynamo- Electric Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention.
In the drawings, Figure 1 represents a front view of my machine. Fig. 2 represents a back view of the same. Fig. 3 represents an interior side view of the same, and Fig. 4 represents one of the parallel bars of which the cylindrical armature is composed.
In my machine the field-magnet consists of two curved pieces of iron connected at their ends by two rectangular plates, from which two other pieces of iron project toward each other, the curved end plates of which form a cylindrical space in which the armature with its coils revolves. As in this shape the iron surrounds the magnet-coils, the inductive effeet in three directions is utilized, making a very strong magnetic field in the cylindrical space, but leaving the external iron neutral.
In the drawings, Figs. 1 and 2, the fieldmagnet is represented by the letters A A B B G O, A A being the yoke, 13 B the rectangular plates connecting the yoke, and C and O the poles.
This strong magnetism, as shown above, is obtained by comparatively a small number of convolutions of the conductor forming the coil, and the latter will therefore have a low internal resistance.
The cylindrical arm z tture is composed of a number of parallel bars, such as are represented byFig. 4, which are held in position by projections N on the same abutting against the conical inner side of the rims of two diamagnetic disks, E, Fig. 2, which are fastened to the shaft. These bars are separated from each other by a space for a large part oftheir length, as shown in Fig. 4, through which space a strong current of air will be forced, entering the hollow interior of the armature by large and numerous perforations, 0, Fig. 2, through the end plates, E, Fig. 3, and being directed toward the circumference by one or more blades fastened to the shaft radially. One or more coils, P, Fig. 3, are wound longitudinallyitround each bar, being held'in" position by the projections N, as shown in Fig. 3. All the ends of one denomination of these coils are coupled together by being attached to a ring, D, Fig. 2, which is fastened to one of the end plates, E, Fig. 3, but insulated therefrom. All the ends of the other denominations of these coils are fastened each to a segment, F, Fig. 1, of the commutator. The currents from these coils are collected quantitatively by a number of brushes, G, Figs. 1 and 3, which number is determined by experiment. As the coils passing the neutral zone would give but little current, they are left out of the circuit till they have attained a more pronounced magnetism.
To enable the operator to set the brushes in that position where the greatest strength of current is obtained, the brush-holder is provided with a tangent-screw, M, Figs. 1 and 3, by which it can easily be moved round its fulcrum, but which secures it against all accidental shifting.
The circuit in this machine is in the usual way--from binding-post on left side to brushholder, through armature-coils, through opposite brush-holder to a magnet-coil, through coil crossing over to the other coil, through the latter to binding-post on the right side.
The peculiar advantages of this machine are, that its internal resistance is kept "cry low, that the current is very uniform, and that there is very little wear to the commutator and brushes on account of the absence of sparks.
I claim- In a dynamo-electric machine, a cylindrical armature consisting of a number of parallel bars held in position by projections on said bars abutting against the inner conical rim-surface of two diamagnetic plates.
IVILLIAM HOGHHAUSEN.
