UNITED STATES PATENT OFFICE,

RUDOLPH M. HUNTER, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE ELECTRIC CAR COMPANY OF AMERICA, OF SAME PLACE.

ELECTRIC RAILWAY.

SPECIFICATION forming part of Letters Patent No. 431,720, dated July 8, 1890. Application filed January 26, 1887. Serial r5. 225,493. (No model.)

To all whom it may concern:

Be it known that I, RUDOLPH M. HUNTER, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Electric Railways, of which the following isa specification.

My invention has reference to electric railways; 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.

In carrying out this invention the car or vehicle is formed with a motor truck-frame supported upon the axles without elasticity, and the car-body is supported upon this frame by means of springs. By this means the motors and connections are rigidly connected with respect to each other and are not affected by the movements of the vehiclebody. By connecting the two axles by the truck-frame the trucks, with motors, &c., may be completed, ready to receive the body. The draw-bar would connect with the truck-frame and not with the body, as has heretofore been the case. The operators levers, 850., are located on the front of the car-body and are connected with the motor by flexible connections. The body portion is prevented from having lateral movement independently of the truck by means of suitable guides. The motors are two in number and are connected with the truck-frame and independently of the car-body, and are geared with the re spective axles, which axles being fixtures in the truck, the connection is perfect. motors, as shown, are arranged end to end, being united at their neutral parts. The commutator-brushes are capable of being 0 shifted for changing the angular advance in regulation or reversing, and both sets of brushes are connected together and to the same operating-lever, whereby they may both be simultaneously moved. The motors are connected together by a circuit, and may be coupled in multiple or series connection, and provision is made for varying the resistance of the motor-circuit.

The foregoing give the general features of 50 my improvements; but it is to be understood The that I do not limit myself to the specific details thus enumerated.

In the drawings, Figure 1 is a side elevation of my improved electrically-propelled vehicle with the upper and end portions of the car-body not shown. Fig. 2 is a sectional elevation of same on line 00 0c of Fig. 3 and showiugthe conduit; and Fig. 3 is a plan view of the truck and its appendages, the carbody and its springs having been removed.

A is the truck-frame, and maybe made in any manner desired, and is provided with axle-boxes A, in which the two axles B are journaled, preferably without elastic play. The side frames or trusses are connected by cross-bars A and d.

O is the car-body, which may be of any suitable construction, and is supported upon the truck-frame by the springs c of any wellknown make.

To prevent lateral movement of the carbody on the truck-frame, I provide guideframes O, secured to the car-body and projecting down and spanning the cross-bars A which is formed with guide-bars 0*, between which the'guide-frames O move vertically. It is evident that the same effect might be produced by bolts passing down through the springs, as shown in Fig. 1. The draw-bar Dis hinged to the truck-frame, and is therefore independent of the car-body and pulls directly from the axles. This draw-bar is shown in Fig. 3.

D D are the two motors, which are secured end to end, being united at their neutral parts, as shown. These motors are supported upon the cross-bars d of the truck-frame, or may be otherwise secured to it, so as to be independent of the car-body. The motors are respectively connected with the axles B 90 by a spur-gear E and pinion e. The brushes f are secured to the brush-levers G, and are movable over the commutator F for varying the lead for regulation or reversing. These two brush-levers G are connected by a rod g, connecting with a lever G on the front of the car-body, the connecting-rod 9 being flexible to allow of the movements to the car-body without affecting the connection. By this lever G both sets of brushes may beshifted I00 simultaneously, and thus both motors may be regulated at the same time and with the same movement.

I do not limit myself to any particular means for shifting the brushes, as it may be accomplished electrically, as set out in my application, Serial No. 216,321, or in any other way. The essential feature is to regulate bot-h motors at the same time and with the same movement of parts. The motors may be of any desired construction, and may be connected with the axles in any desired manner, that shown being simply one form of connection to illustrate the general features of the invention.

In this application I do not claim the construction of the collector for supplying the current to the motor, but have shown sufficient of such a construction to make the in-" vention clearly understood. The collector here shown consists of a frame H, running upon awheel J and connected to the motor frame or truck by bar h. The frame H supports the contact-shoes, which extend down into the conduit K, in which the conductors 7c are supported at some distance above the bottom M. O are supports for the conduit. It is evident that the motors may receive their current from storage-batteries or overhead conductors or in any other way, as this invention has no particular reference to the source of supply.

R is the motor-circuit and connects both motors in circuit with the contact-shoes i i. The current may be regulated by the resist: ance-changer 7', which may be operated by a lever or handle 8 on the front of the car-body, as in the case of the lnush-shifting devices. As shown in Fig. 2, the motors are in parallel or multiple circuit, but-may be put in series connection by switches'l" when necessaryas, for instance, in starting, or when the potential of the current has greatly increased and volume of current decreased from any cause.

The foregoing is a general description of the details of construction illustrated; but, as I have before stated, these details are given simply as one method of carrying the invention into effect, and I do not in any wise limit myself to the details herein set out.

I do not here claim the simultaneous shifting of the brushes of the two motors to reverse both motors simultaneously.
