UNITED STATES PATENT JOHN BATLEY, OF PHILADELPHIA, PENNSYLVANIA.

ELECTREC MOTGR.

SPECIFICATION forming part of Letters Patent No. 388,753, dated August 28, 1888.

Application filed June 29,1887. Serial No. 242,840.

To all whom it may concern:

Be it known that I, JOHN BATLEY, of the city and county of Philadelphia and State of Pennsylvania, have invented an Improvement in Electric Motors, of which the following is a specification.

My invention has reference to electric motors; and it consists in certain improvements, all of which are fully set forth in the following specification, and shown in the accompanying drawings, which form part thereof.

The object of my invention is to employ the direct attraction of the armatures of a series of electro-magnets to vibrate a series of levers, which in turn cause a rotary movement of the motor-shaft. The construction embodied in my invention is simple and positive, and by a proper number of electro-magnet elements being employed I am enabled to make the motor of any power desired. The magnets are arranged or coupled in two series, which are adapted to become energized alternately, and each of the electro-magnets is preferably supplied with electrical current from a separate battery. By cutting out one or more of the batteries the corresponding electro-magnets are cut out, and hence the power of the motor may be correspondingly increased or de creased. An important feature of my construction is that the operating-levers which act on the motor-shaft are caused to operate automatically, whether their operating-magnets are energized or not, so that all of the moving parts shall maintain a constant relation with each other and all danger to breakage due to irregular movements becomes obviated.

In the drawings, Figure 1 is a side elevation of an electric motor embodying my improvements. Fig. 2 is a plan View of same showing the connection with the batteries. Fig. 3 is a perspective view showing the construction of thearmatures, operating-levers, and friction-wheels; and Fig. e is adia-gram showing the complete circuit between one battery and one operating eleetro-magnet.

A is the frame of the machine.

13 is the central stationary hub or frame, upon which the radiating eleetro-magnets O and D are secured. These electromagnets O and D are arranged in two series placed (No model.)

I side by side, and preferably staggered. The pole'pieces of these magnets are curved, though this is not an essential feature of the construction.

E is the motorshaft, which isjournaled in the frame A, and is provided upon each end with a circuit breaking and making commutator, F, and a friction-wheel, H. This frictionwheel is shown in elevation in Fig. l and in perspective in Fig. 3, from which the construction may be clearly understood. It consists, essentially, of a notched wheel having the alternate projections I and notches J, the outer surface of the projections I being eoncentric with the shaft E, to which they are secured. The forward end of the projections I are provided with projections t, the purpose of which will be hereinafter explained.

L represents the armatures for the magnets G, and are pivoted at 7r, so as to vibrate to and from the pole, and for effect they are made curved to tit close to the said pole-piece of the magnet. These armatures vibrate a series of friction levers, K, provided on their lower parts with adjustable sections K, made adj ustable by means of slots and clamping-screws k, and the lower portions of said parts K are made curved from 7; as a center,and are adapted to press in contact with the projections I of the wheels H, so as to form a rolling frictional contact. By the vibration of the armatures L it will be seen that the wheel H will be rotated a portion of a revolution, and then the friction-levers will return to their normal position ready for the nextaction, and so on, returning in the spaces J without contact. To prevent the shaft E spinning or moving faster than it should with a given number of vibrations of the levers K, the steps or extensionsi are provided and are adapted to strike against pins 3 on the lower part of the levers K,which pins are adapted to act as stops to arrest premature rota-tion. The rear ends of the lovers K are provided with extensions 72, which are adapted to fit down at the rear of the projections I and insure a positive thrust to the wheel H at or about the termination of a semi-vibration. From this it will be seen that the wheel H is estopped from running at a too high velocity, and while it is driven by frictional con tact with the levers a positive thrust is also insured with each vibration of the lever. The adjustment of the part K allows the wear to be taken up and insures a good firm contact. As shown in the drawings, there are six sets of magnets in each series, and consequently six levers K on each side; but I do not limit myself to any number, as one or more may be used. The levers on one side of the machine are thrown backward, while those upon the other side of the machine are thrown forward, so as to keep up a constant forward motion of the shaft E. To enable the proper action of these levers when so arranged, the wheels H are so set that the projections I on the two wheels are staggered. (See Fig. 3.)

M represents the armatures for the D series of electro-magnets, and are pivoted at m and secured to the other series of levers K. (See Fig. 3.) The armatures M and L are connected together by means of an arm, L, extending rearwardly from the armature M, and having a slot, m, and into which extends a pin, Z, secured to the free end of the armature L. From this it will be seen that as the armature L is attracted to its magnet the armature M is raised, and vice versa, and in this connection it will also be observed that the backward movement of the levers K are caused by the attraction of the magnets in the other series to which they belong, thereby avoiding all the necessity of springs or counterbalances, and also the employment of but a minimum number of electro-magnetic elements.

Grepresents the commutator-brushes, which are arranged in pairs,so that the current passes down one brush through the commutator and back through the other brush. One of these brushes of each pair leads to its battery R and the other brush leads to one of the electromagnets of the motor, and the current returns to the battery by a circuit having a switch, S. This is clearly shown in Fig. 4., and is simply duplicated in the plan view, Fig. 2. Each electro-magnet of the two series is provided with its own complete circuit Q, and its own battery and its own switch S to open the circuit Q. As the commutator F rotates, the magnets of the two series are alternately energized, and thereby keep up a continuous action upon the motor-shaft.

If desired, one or more of the magnets G and D may be simultaneously cut out of action by means of the switches S; but from the nature of the construction of the friction-levers and friction-wheels the armature and levers will continue to work even though their particular magnets are not energized.

\Vhile I prefer the construction shown I do not limit myself to the details thereof, as they may be modified in various ways without departing from my invention.
