TRACTION MOTOR.
APPLICATION FILED MAR.27. I920.
Patented Apr. 12, 1921.
WIT/VESSES A TTUHNEYS UNITED STATES PATENT OFFICE. I
GEORGE YATS, OF CLEVELAND, OHIO.
TRAorioN-'Moroa To all whom t may concern:
Be it known that I, GEORGE YA'rns, a citizen oi the United States, and a resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Traction-Motors, of which the following is a speciiication.
My invention is an improvement in traction motors, and relates more particularly to the rotating` armature type. D
An important object of my invention is to provide a traction motor in which the effective driving power will be transmitted directly to the car wheels, thereby eliminatingthe use of transmission gearing, and increasing its eliiciency.
Another important object is to provide a traction motor which may be easily inspected and cleaned.
Another orbject is to provide an apparatus of the above named character which will be simple in construction and comparatively inexpensive to manufacture. y
Other objects will become apparent during the course of the following description.
In the drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,
Figure 1 is an elevationpartly in section of the motor embodying my invention,
Fig. 2 is a vertical section on` the line y 2--2 or Fig. 1, showing the bearings, and
F ig. 3 is a vertical section on the line 3-3 of Fig. 1, showing thecommutatofr and brushes. f
ln the drawings, the car wheels 5 and 6 are mounted upon a cylindrical casing 7 lat Y its opposite ends. The wheels 5 and 6 are secured against outward displacement by the face plates 8 and 9 which are bolted to the casing l and revolve with it. t)
Within the casing 9 is secured an outer bearing track 10 and an inner track 11 adapted to accommodate roller bearings 12. A similar construction (not shown) is provided at the opposite end of and within the casing 7. rlhe roller bearings 12 are separated by a ring 13 and are held `against lateral movement by the face plate 9 and a web 14E.
A commutator 15 is mounted within the casing 7 and is attached thereto by any suitable means. Also mounted within the casing 7 is an armature 16 which is con- Specicaton of Letters Patent. Patented Apr. 12, 1921. Application Ied March 27, 1920. Serial No. 369,227. Y
place, such as directly over each brush. It
will he noticed that so far I have confined my description to the rotating part of my invention. The axle 18, which is stationary, is -provided with a supporting ring of insulating material 19 upon which are mounted the brushes 20. Set screws 21 serve to clamp brushes 20. The inner walls of the hollow axle 18 are provided with contact blocks A and B insulated from the axle by any suitable insulating material C. The field magnets 22 are mounted upon the axle 18 as shown in Fig. 1. Current is supplied through the end of the aXle and conveyed to the brushes and ield through wires 23 and 24 housed within the axle 18.
ln use, current is supplied through the end of axle 18 to the brushes 20and field 22. Due to the magnetic iux set up in the kiield and the current in the armature coils,
the armature 16 will revolve, moving with it the casing 7 and wheels 5 and 6. It will be noticed that the full turning effort is transmitted kdirectly to the Wheels, thus eliminating much loss due to the use of gearing or other power transmission mechanism.
It is to be understood that various changes in the size, shape and arrangement of parts maybe resorted to without departing from the spirit of the invention or the scope of the subj oinedclaims.
Iclainiz* 1. A traction motor, consisting of a cylindrical wheel carrying casing, a shaft within the casing, antifriction bearing between the casing and the axle, a motor armature secured to the casing, a commutator also secured to the casing, and brushes carried by the axle and delivering electric current to the commutator.
2. A traction motor comprising a cylindrical casing, a pair of tractor wheels mounted upon the casing and adapted to revolve with the casing, a motor armature secured to the casing, a commutator secured to said casing, and stationary brushes mounted upon an axle to deliver electric current to the commutator.
3. The combination of a stationary axle, eld magnets and brushes mounted intermediate the ends oli' said axle, a Cylindrical casing', an armature and commutator can i'ied by the casing, and a pail` of Wheels mounted one upon each extremity of said easing and adapted to revolve with the casing.
4. rlhe combination of an axle? a ield and brushes ea'iied by the axle, a pair of Wheels rotatably mounted on the axle, an armature and Commutatoi, and suppoiting ine-ans 'foi said armature and oommutatoi, seid suppoiting means being` rigidly secured to each of the wheels and adapted to iotate with the Wheels.
5. ln an electric motoi, a hello7 snafu held magnets and brushes Carried by said shaft, eleetiical conductors eaiiied Within the axle to deliver eleotrie current to the brushes, an outer body portion rotatably mounted upon the axle, an armature and commutatoi' cairied by the outer body poi'- tion, and Wheel rims mounted upon the extremities of the body portion.
6. ln a traction motor, a hollow axle, a plurality of Contact blocks mounted Within the axle for protection and insulated therefrom, and means for delivering an electric current from the blocks to the motor.
7. ln tiaotion motor, an axle, a Wheel Caiiying; easing', a fade plate seoued to eaoh d of the casing, similai plates yWithin the asing and in close proximity to each end alato, and 'antiiiotion bearings mounted :ietween said plates and end plates.
