IMPRGVEMENT 5N ELECTRQ-MAGNETIC MOTORS.

Specification forming part of Letters Patent No. 131.377, dated September 17, 1872; antcdated September 9, 1872.

To all to whom it may concern:

Beit known that I, ADOLPH SOHREIBER, of Brooklyn, E. D., in the county of Kings and State of N ew York, have invented a new and Improved Electro-Magnetic Motor; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same,reference beinghad to the accompanying drawing formin g part of this specification, in which drawing- Figure l represents a side view of this invention. Fig. 2 is a plan or top view of the same. Fig. 3 is an end view of one set of electromagnets, showing their connection with each other. Fig. 4 is a transverse section of my apparatus showing the commutator.

Similar letters indicate corresponding parts. y This invention consists in the combination of two sets of electro-magnets with each other and with a commutator, one set ofelectromagnets being mounted on a stationary pin opposite the other set, which is mounted on a revolving shaft, on which is also secured lthe commutator in such a manner that when currents of electricity are passed through both sets of electro-magnets, and the movable electro-magnets are so placed as to bring their poles opposite to the homonymous poles of the stationary electro-magnets, then, by the repulsion of the homonymous poles and by the attraction of the heteronymous poles, the movable electro-magnets are caused to revolve, and as the polarity of these electro-magnets is constantly changed by the commutator, a continuous revolving motion is imparted to the shaft carrying the movable electromagnets. By connecting both sets of electro-magnets to one and the same battery the power ofthe motor is materially increased.

In the drawing the letter A designates a pin, which is secured in a standard, B, rising from a table, C, and on this pin is firmlysecured a disk, D, on which are fastened a series of electro-magnets at equal distances apart. (See Fig. 3.) In the drawing I have shown eight electro-magnets, which I have designated by the letters E1 EZES. E8, but the number of the electro-magnets may be greater or smaller, according to the diameter of the disk D and to the power desired. One end of the helix of the electro-magnet E1 connects by a wire, l0,

with one-say the positivepole of a galvanicbattery, F, while the other end of said helix connects with the helix of the electro-magnet E2, which connects with the helix of the next electro-magnet E3, and so on,while the end of the helix ofthe last electro-magnet E8 connects by a wire, ll, with the negative pole of the battery. By these means the poles of the electromagnets El, E3, E5, and E7 will be north, and those of the electro-magnets E2, E4, E6, and E8 will be south, as indicated by the letters N and S, marked, respectively, on said electromagnets in Fig. l. The end of the pin A is sharp pointed to catch in a hole bored in the center of a shaft, H, which is mounted in a standard, H', rising from the table C, so that it revolves freely in its bearings. On this shaft is mounted a disk, I, carrying a series of electromagnets J1J2J3 J 8, which correspondin number and position to the electro-magnets E1 .E, and the helices of all of which are connected together, with the exception of those of the electro-magnets J1 and J 8, which are connected at one of their ends each to one ofthe sections of the commutator K. This commutator consists of a disk of wood or other non-conducting` material, surrounded by a strip of metal, which is divided in anumber ofsections, falaz a3. a8, corresponding to the electro-magnets J1. .J B, the sections al, a3, a5, and a7 being in metallic contact, (see Fig. 4,) and also connected to the en d of the helix J1, while the sections, a2, a4, a, and a8 are also in metallic contact with each other and connected with the helix J 8. On the eircumference of the commutator K bear two springs L1 L2, the spring L1 being connected by a wire, 13, with the positive, and the spring L2 by a wire, 14E, with the negative pole of the battery. If the shaft H occupies the position shown in the drawing the poles of the electromagnets J1, J 3, J5, and J 7 are north, and those of the electro-magnets J 2, J 4,' J 6, and J 8 are south, and the hornonymous poles of the electromagnets Elr E8 repel those of the electromagnets J1.. .J8, causing the shaft H to revolve. As soon as the commutator spring L1 passes on the segment a4 and the spring L2 on the segment c5, the current through the electromagnets J1 .J 8is reversed, and bythe time the electro-magnets J 2, J 4, J @and J 8have advanced to the positions previously occupied by the electro-magnets J1, J3, J5, and J7, the poles"A have changed, those of the former to north and those of the latter to south. The motion of the shaft H, therefore, will continue Without interruption. The pin A, which supports the electro-magnets El. .E, cany be turned in its standard, and it will readily be seen that, by turning the same so that the electro-magnets E2, E4, E6, and E8 will come in the posiytion previously occupied by the electro-magnets E1,E3,E5, and Erl the motion of the shaft H will be stopped, for in this case the south poles of the electro-magnets El. .E8 would stand opposite the north poles of the electro-magnets J1 J 8, and vice versa; but, by turningthe pin A to an intermediate position, the motion of the shaft H Will only be retarded Without being stopped entirely, and I am thus enabled to regulate the speed of my machine in a very.

simple manner and with the greatest nicety. It Will be noticed that both sets of electromagnets E1. .E8 and J1. .J8 are connected to the poles of one andthe same battery, for I have found that, by using one and the same battery for both sets of electro-magnets, the power of my machine is materially increased. This phenomenon I am unable to explain, but

the fact is undoubted, and l expect, by further experiments, to detect or explain the cause producing this effect.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination of two sets of electromagnets with each other and with` a commutator, one set of electro-magnetsbeing mounted on a stationary pin opposite the other set,

which is mounted on a revolving shaft, also` Witnesses W. HAUFF,.. E. F. KAsrENHUBER.
