ELECTRIC LOCOMOTIVE.

' Specification of Letters Patent.

Patented. Jan. 21, 1 908.

Application filed October 18 1906- Serial No. 339.497.

To allwhom it may concern:

Be it known that I, RIOHAR SOHWARZ, a subject of the Emperor f'G1Il1&Il-',.I6Sitl ing at Schenectady, county of Schenectady,

5 State of New York, have invented certain new and useful. Improvements in Electric Locomotives, of which the following is a specification. J

.My invention relates to electric locomotives of the type if; which the armatures of the driving motors surround the driving axles and have their torque transmitted to the driving-wheels bymeans of spiderscorinected to the driving-wheels by compressionsprings; and its object is to provide a novel .construction which, without sacrificing strength, renders possible the use of longer springs than has been possible heretofore. Since the spokes of the driving-wheel must the spider must be brought into the plane of the spokes of the driving-wheel in order to avoid twisting strains on the springs, the spaces between the spokes of-the spider and driving-wheel have been small with constructions used heretofore, so that short springs were necessary. If these short springs are made sufficiently stron they become too rigid for satisfactorily re ieving the armature from shocks. By my invention I am enabled to increase the length of spring,

so as to obtain greater elasticity without decreasing the number or size of spokes. I accomplish this by making one set of spokes, for instance, the spokes of the spiderhollow, so that eachspoke of the spider can partly surround one spoke of the driving wheel. With this construction, if a spring is placed between one of the spider spokes and 40 an adjacent wheel-spoke, the length of the spring may be almost as great as the dis tance between the'spokes of the wheel.

. My invention will best be understood by reference to the accompanying drawing, in

which Fi ure 1 shows an elevation of a drivingwhee and supporting spider viewed from the I inside of the wheelwlth the armature re-.

moved; Fig. 2 showsa cross-sectional elevation of the same on the line 2-2- of Fig. 1;

be large or numerous, and since-the spokes ofand Fig. 3 shows a cross-sectional detail view of the spokes.

In the drawings, A represents the driving axle, on which is mounted the drivingovhccl B provided with spokes b.

C represents the armature of the driving motor, which loosely surrounds the axle A, and is carried by the spider l), which is provided with the spokes (1. Each of the spokes (l is made hollow, as shown in cross-section in Fig. 3, and partly surrounds a spoke b of the driving-wheel, there being space enough in the hollow s okes (l to allow movement of the wheel spo 'es 1) therein. Compression springs E are placed between each spoke (Z of the spider and theadjaccnt wheel-spokes b, which may support the weight of the armature besides transmitting the driving torque from-the armature to'the wheel. The length of these springs, as is seen from Fig. 1, is

nearly equal to the distance between the ture is obtained without reducing the number or size of spokes of the driving-wheel.

What I clann as new and desire to secure by Letters Patent of the United States, is,-

1. In an' electric "locomotive, a drivingaxle, a spoked driving-wheel thereon, a motor armature surrounding said axle, a supporting spider for said armature, and compression-springs between the spokes of said Wheel and said spider, one set of spokes being I hollow and partly surrounding a portion of the spokes of the other set.

ii anelectric locomotive, a drivingaxle,a spoked drivingwheel thereon, a motor armature surrounding said axle,a sup-:-

orting spider for the armature having hol- Ow spokes, each partly surroundmga spoke of said wheel, and compression-sprmgs between the s okes of the spider and the adjacent whee spokes not surrounded thereby,

- .In witness whereof, I have hereunto. set my hand this 17th day of October, 1906.

.. RICHARD SCHWARZ.
