IMPROVEMENT IN ELECTRO-MAGNETIC ENGINES.

Specification forming part of Letters Patent N 0. 155,062, dated September 15, 1874; application tiled August 21, 1874.

To all whom it may concern:

Be it known that we, LOUIS BASTET, of Tarrytown, Westchester county, New York, and CHARLES J. B. GAUME, of Brooklyn, Kings county, New York, have invented certain new and useful Improvements in Electro- Magnetic Machines, of which the following is a specification:

The object of our invention is to utilize, as far as possible, all the available attracting surface of the magnet in an electro-magnetic motor, with a view `of imparting increased power to the machine. To effect this result, we combine with the electro-magnets and set or series of revolving armatures usually found in such machines, extra or auxiliary armatures, independent of the main series of revolvin g armatures, and arranged to transmit, by their independent movement, power which is in addition to that obtained from the main set of revolving armatures.

The accompanying drawing represents one way in which our invention is carried into effect.

Figure l is a perspective view of an electromagnetic machine embodying our invention. Fig. 2 is a side elevation of the same.

As many electro-magnets, A, as desired, may be employed. In this instance we have represented two. In bearings in the frame B is supported the main shaft G, which carries the armatures a, iixed on radial arms b, extending from a hub, c, fast on shaft O.v The commutator consists of the circuit-breaker wheel d, on shaft C, and the insulated adjustable friction-wheels e, bearing on the circuitbreaker, and properly connected each with its own electro-magnet. The battery-connections are made by means of binding-screws j.V The combination of these parts, as well asthe arrangement of the circuit, is not new with us, and the operation of the machine thus far described will be understood without further explanation. Only the end surfaces of the, electro-magnets are availed of when using the revolving armatures a,- but these end surfaces do not constitute, by any means, the Whole of the attracting surface, the sides of the cores adjoining the poles being quite as available.

To utilize, therefore, these side surfaces, we combine with each magnet one or more vibratory armatures, independent of the main series of revolving armatures, and geared or connected with the driving-shaft by suitable intermediaries, so as to impart to that shait power superadded to that derived from the armatures a. The arrangement of these extra or auxiliary armatures may be considerablyvaried, and so, also, may be the means by which they are connected with the drivingshaft.

One convenient arrangement for the purpose is represented in the drawing. Vith each electro-magnet is combined a pair of vibrating armatures, g g/ one on each side of the magnetmounted each on an arm, h, projecting from a rock-shaft, f, supported in a suitable bearing in frame B. Each armature vibrates on its shaft i as an axis. Projecting from the rock-shaft of the outer armature of one pair, and the inner armature of the other pair, is a second arm, j, to which is jointed a connecting-rod, hung at the other end on a wrist or crank pin on a pinion, k, that gears with the large spur-Wheel Z on driving-shaft B. The two pairs of vibrating armatures are connected by means of jointed rods, of which the rod m connects the interior opposite armatures g g ofthe two pairs, and the rod a the" exterior opposite armatures g g.

It is understood that when the circuit through the one electro-magnet is broken, it is closed in the other. It will consequently be seen that, when the one armature, g', is attracted, the other one, g', will be free to move back, and the same is true of the armatures g g. It will also be seen that each set g g, g g', drives one of the pinions k, and that, consequently, the attractive force exerted to draw the armatures to the magnets is being constantly exerted on each pinion through the instrumentality of one or the other of the armatures assigned to operate that pinion.l Thus to the power derived from the combination of the electro-magnets and main set of revolv ing arlnatures is added that derived from the combined action of extra and independent armatures, and the same electro-magnets,

Whose attracting surfaces are, therefore, utilized to a much greater extent than has heretoi'ore been the ease.

As hereinbefore intimated, we do not limit ourselves to the special mechanical contrivances herein shown in illustration of our invention, for it is manifest that the same may be varied to a great extent without departure from the principle of our invention; but

What we do claim, and desire to secure by Letters Patent, is-

l. In an electro-magnetic motor, the combination, nith the electro-magnets and main set of revolving` armatures of extra or auxiliary vibrating armatures, arranged and operating to impart to the driving shaft, through proper intermediaries, power in addition to L.
