WITNESSES: I INVENTOR Geo/fqeHF/v o/f v BY /' ATTORNEY of Pittsburgh, in the county running in service, it is essential. to provide LOGOMOTIVE.

Application filed May 2, 1917.

To all whom it may concern: n Be it known that I, GEORGE H. F. HOLY, a citizen of the United States, and a resident of Allegheny and State of Pennsylvania, have inventedia new and useful Improvement in Locomotives, of which the following is a specification, I

My invention relates to locomotives and particularly to electric locomotives that are provided with jack-shafts and side-rods for transmitting the driving effort of thepropelling motors to the associated driving wheels.

One object of my invention is to provide a locomotive which shall be simple and rugged in. construction and have the various driving parts of the running gears conveniently disposed for repair and replacement and for developing a maximum drawbar pull.

Another object of my invention is to pro vide a locomotive having a single running gear or a plurality of articulated running gears pivotally connected to the cab thereof, each. of the running gears being provided with a plurality of pairs of driving wheels having a fixed whechbase, jack-shafts disposed adjacent to said driving wheels and outside the rigid wheel-base, a plurality of motors connected. to the jack-shafts, and side-rods for connecting the jack-shaft to sciectcd pairs of the driving wheels.

Another object of my invention is to provide a lOQOl'llOillVP/Uf the ulmve-indicatcd character which shall lie provided with a gear comprising four pairs of driving wheels having a lixcdwheehbase, two iaclcshafts and two aumhary trucks disposed adjacent to said driving wheels, aphrrality of motors connected to said ackshafts, and side-rods for connecting each inch-shaft to various pairs of the driving' wheels.

in electrical locomotives that are to replace steam locomotives that adapted are now a struc ture which shall develop a maximum drawha r pull and have good tracking characteristics. The propelling motors should be conveniently located relati e to the driving wheels in order to obtain the maximum clliciency from the motors and transmit the driving effort of the i'notors to the driving wheels in a simple and economical manner.

The electrical locomotives must not only develop a greater draw-bar pull than the steam locomotives, but must be capable of being operated at various speeds with a minimum injury to the road-bed over which the vehicles are operated. I

In a locomotive constructed in accordance with my invention, the motors and the driving wheels are advantageously located and are connected together in such manner. as to obtain a locomotive that shall develop a maximum draw-bar pull at moderate speed and have good tracking characteristics.

In the accompanying drawing, Figure l is-a side elevational view of a portion of a locomotive constructed in accordance with Joy/invention; ,Fig. 2 is a plan view of the gears of the locomotive illustrated in Fig. 1 Fig. 3 a partial elcvational view of a locomotive provided with .a f0llr-Whcel auxiliary truck, and Fig. 4 is a fragmentary view of a modified locomotive having a single motor connected to each -jack-shaft.

Referring to Figs. 1 and 2 of the drawing, a locomotive l is provided with a cab 2 and two articulated running gears 3 and 4, which are connected to the cab 2 by pivotal connections 5, one only of which is illustrated. Each of the running gears embodies side-frames 6 and pairs of driving wheels 7,8, 9 and 10, which are respectively mounted on the driving axles 1 1, l2, l3 and 14, and have a fixed wheel-base. A pack-shaft 15, having gear-wheels 16 mounted thereon, is disposed on the side-frmncs adjacent to the driving wheels 7, and a similar jackshaft 17, having gear-wheels 18 mounted thereon, is located adjacent to the driving wheels 10. Two motors l9 and 20, having armatures 21 and that are tandem-mounted on a shaft 23, are located above the jackshaft 15, and two pinions 24, which mesh with the gear wheels 16, are mounted on the opposite ends of the armature shaft 23. Two motors 25 and 26, having armaturcs 27 and 28 that are tandcm-mountcd on a shaft 29, are locatcdnbove the jack-shaft 17. "we {)iL-iOIlS 30, which mesh with the gear-wheels 18, are mounted on the opposite ends of the armature shaft 29.

Two two-wheel radial auxiliary trucks 31 and 32 are disposed outside of the jackshafts 15 and 16 and may be corrected to thc sidc frames 6 in any convenient and approved manner.

as is illustrated in Fig. 3

. to be covered posed ad jacent to said The gear-wheels 16, which are mounted on the jack-shaft 15, .are provided with cranks.34 that are connected to cranks 35 and 36 of the driving wheels 7 and 8 by means of the side-rods 37. The gear-wheels 18, which are mounted on the'jack-shaft 1.7, are provided with driving cranks 38 that are connected to similar driving cranks 39 and 40 of the driving wheels 10 and 9 by means of side-rods il. I

The locomotive disclosed in Figs. 1 and 2 of the drawing and which is provided with two two-wheel auxiliary trucks, is preferably adapted for frei ht service and not for high-speed service. owever, in case the locomotive is to be operated at high speed, as, for example, in assenger service, the guiding truck is provided with four wheels of the drawing.

Although the locomotive illustrated in the drawing is provided with articulated run ning gears, it is obvious that a locomotive may be constructed with a single running gear, inwhich case the running gear should be provided with two four-wheel auxiliary trucks.

The locomotive illustrated in Figs. 1 and 2 of the drawing is preferably provided with twovpropelling motors for each .jack-shaft. but, if so desired, each jack-shaft may have one motor connected thereto as is illustrated in Fig. 4 of the drawing. Modifications in the structure and arrangement and location of parts may he made within the spirit. and scope of my invention and such modifications are intended by the appended .claims.
