Applieatian ned May 1a, 1912. sei-mnt. 696,828.
To `aZZ whom, t may concern.'
Be it known that I, HENRr G. CHATAIN,
a citizen of the United States, residing at Erie, in the county of Erie, State of Pennsylvania, have invented certain new and useful Improvements in Locomotives, of which i'i' the following is a specification.
The present invention relates to locomotives and has for its object to improve and vfacture and alinement.
. wardly from the base portion of the engine frame are parts of the magnet frames of the motors, said frame parts being parallel and arranged in pairs, each pair embracing an axle and the rotor of the motor. On these frame parts or pieces are mounted pole coils for the field magl pieces and energizing nets of the motors. The under side of the i.. engine frame adjacent the rot-ors of the and windings-to the armature or rotors on tures can be removed from below.
motors must be of such cross-section that it will carry the magnetic flux due to the field windings. The relation of the field poles the axles is such that the trucks and arma- The entire weight of the engine, generator, and pole pieces of the motors is carried by. the
' cab or body of the4 locomotive and said cab or' body is supported upon springs carried by the trucks. Y I have illustrated my invention 1n con-' nectionfwith a locomotive having two trucks, and owing to the fact that the engine, generator and magnet frames of the motors form a.l unitary structure care should be exercised not to make the wheel base too long, since otherwise the locomotive would vnot readily go around curves in the track.
In vthe accompanying drawing, which 'illustrates one of the embodiments of my invention, Figure 1 is a side view,pa rtially in Specilcaton of Letters Patent.
Projecting down-A ratentea oct. 21, 1913.
section, of my improved locomotive, and
Fig. E2, is a transverse sect-ion thereof.
.l indicates the cab of the locomotive which `.ay be of any suitable shape and construction and is provided with floor sills 2. Located within the cab is a multi-cylinder internal combustion engine that is divided into two principal arts 3 and t. Between these parts is locate an electric generator Whose field magnet frame 5 acts as a connecting member to unite the base portions 6V` and 7 of the engine. The means for uniting the parts is also shown in F ig. 2 where 8 indicates a flange formed on the engine base, which is secured to the field magnet frame of the generator by bolts 9.
The engine is provided with laterally extended feet l0 that rest on the main sills 2, the latter being formed of I-beams. The base of the engine is divided into upper and lower parts, the plane` of division being horizontal and coinciding with the aXis of the main shaft l1. T he shal ft 11 is common to both parts of the engine and also to the armature 12 of the electric generator. The shaft may be made in one piece or in two or more pieces united by couplings.
13 indicates the commutator of the generator, the brushes therefor having been omitted to simplify the illustration.
Two trucks 14 are provided which may bel of any suitable construction. Each truck is provided with two leaf springs 15 located on opposite sides. These springs are secured to the sills of the locomotive cab by the hangers 16.. rThe sides of the truck are united by a frame 17. These trucks are not arranged to swivel under the locomotive asit is commonly the. case. Mounted on each truck axle are the usual track wheels and the rotor or armature 18 of. an electric 4motor.
Depending from the base of the engine frame are projections 19 that are arranged in pairs, each pair being situated on opposite sides of an axle. These projections are integral with the base of the engine and form a part of the magnet frame of the motors. n order to carry the magnetic flux .between these projections, the lower wall of the engine base vhas to be thickened as indicated at 20. Referring to Fig. 2, it will be seen that the projections 19 are relatively long and narrow. Their width is "determined by the length of the armature 18.
I' Each projection 19 is provided with a pole piece 21 having a pole shoe 22 and on each pole piece and shoe is a field winding 23. Each armature provided with a commutator Q4, the brushes and the brush rigging having been omitted to simplify the illus tration. All of the motors are similarly constructed and hence further description is unnecessary. The motors are adapted to receive current from the electric generator subject to controlling mechanism of any suitable character.
It will be observed that the diameter of each motor armature is slightly less` than the'distance between the ield cfils. This permits the engine and motor field magnets to move up and down with respect to the armature 18 and the axles i' nder the action of springs 15. This same arrangement permits otremoving the lrucks by raising the engine and.cab, or, what is the equivalent,
holding the engine and cab in fixed position and lowering the trucks.
My improved arrangement has the great advantage of simplicity and strength. T he lower haltof the engine base or fra-me with its projections is a simple casting to maire and machine. The surfaces that require ,machine work are perpendicular' to each other, which makes for ease of manufacture, and such machine operations as are necessary are ofl a very simple character. By uniting the parts of the engine base through the eld magnet 5 of the generator an exceedingly rigid structure is obtained and one that is not liable-to get out of line or bc sprung. By providing each part of the engine base with laterally projecting feet 10 which rest on the main sills 2, the weight of the engine is well distributed and it can be securely fastened in place. As shown, the generator is entirely supported by the adjacent ends of the engine trame, although it may be provided with feet on opposite sides to rest on the sills if'desired.
In accordance with the provisions of the patent statutes, I have described the principle of operation of'my invention, togetherwith the apparatus which I now consider to represent the best embodiment thereof; but
I desire to have it understood that the apparatus shown is only illustrative, and that the invention can be carried out by other means.
What I claim as new, and desire to secure by Letters Patent of the United States, is
