ELECTRIC LOCOMOTIVE.

SPECIFICATION forming part of Letters Patent No. 567,662, dated September 1 5, 1896.

l Application filed September 8, 1895. Serial No. 561,314. `(No model.)

invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in electric locomotives; and it consists in certain novel features of construction whereby to afford simple and eflicient yielding connections between the motor-casing and axle.

In the accompanying drawings, Figure 1 is a view illustrating an embodiment of my improvements. Fig. 2 is a sectional view.

A represents an axle having wheels B secured thereto. A frame O is mounted on the axle, so that its free end can swing ver-l tically, and comprises a sleeve a, made in two parts 1 2, bolted together, and parallel arms b Z). The arms l) o are made at or near their free ends with bearings for the accommodation of hollow trunnions 3, projecting from the motor-casing D, said motor-casing also having a suitable flexible connection with the truck-frame of the car. At the side next to the sleeve a, on the axle, the motor-cas ing is provided at or near its ends with lugs or ears 4, each having an open slot 5 for the accommodation of a vertical rod or bolt 0. The lower ends of the rods or bolts 6 are made with angular heads 7, having their seats in similarly-shaped recesses 8 in the bottoms of pockets 9, made on the upperhalf 1 of the sleeve a. The pockets 9 are not directly over the longitudinal axis of the sleeve, but are disposed to one side or rearwardly thereof, so that the bearings ofthe rods or bolts 6 will not be `immediately over the longitudinal axis of the axle, but rearwardly thereof. Springs l0 encircle the rods or bolts G and have their bearings in the pockets 9 and against the under faces of the lugs or ears 4, respectively. Similarsprings 11 are located on the rods or bolts 6 between the upper faces of the lugs or ears 4t and disks or washers 12 at the upper ends of said rods or bolts. The disks or washers 12 are retained in place on the rods or bolts by means of nuts 13, and the latter are preferably provided with suitable nut-locks 14. The armature of the motor is connected with the axle through the medium of suitable gearing, and

the latter is inclosed by a gear-casing 15.

From the combination and arrangement of parts above described it will be seen; that the motor is mounted in a frame connected with the axle and capable of a vertical swinging motion,.and that the side of the motor next to the axle is flexibly supported by the sleeve of the swinging frame at points outwardly removed from the longitudinal axis of the axle. IVhile the'motor is located to one side of the axle, it is not supported solely at one side thereof, but a portion of its weight is brought to bear on the sleeve of frame O at the side of the axle opposite the motor.

Having fullydescribed my invention, what 'I claim as new, and desire to secure by Letters l. In an electric locomotive,the combination with an axle and a swinging frame mounted on the axle, said frame having arms projecting laterally from the axle, of a motor-casing mounted between the arms of the swinging frame, lugs projecting from said motor-casing, pockets in the swinging frame at the opposite side of the axle from the arms of said frame, rods or bolts passing through said lugs and seated in said` pockets, `washers or disks at the upper ends of said rods or bolts, springs bearing against said lugs and washers or disks and other springs seated in said pockets and bearing against the under faces of said lugs, substantially as set forth.

2. In an electric locomotive,the combination with an axle anda vertically-swinging frame `mounted on the axle, of a motor-casing mounted in said vertically-swinging frame, lugs projecting from the side of the motorcasing next to the axle, said lugs being located in proximity to the ends of said casing, pockets on the part of the swinging frame `which is mounted on the axle, rods or bolts seated in said pockets and passing through the lugs on the motor-casing, disks on the upper ends of said rods or bolts, springs seated in the pockets and bearing against the lugs and springs disposed between the lugs and disks, substantially as set forth.

3. In an electric locomoti ve,the combination ICO With an axle and a swinging frame mounted on the axle, of `'a motor-easing mounted in the swinging frame, pockets formed on that part of Jthe swinging frame which is mounted on the axle, said pockets having recesses in their bottoms, lugs projecting from the motoroasing, rods or bolts passing through said lugs and having heads seated inthe recesses in the pockets, springs on said rods seated in said pockets and bearing against the lugs, and other springs on said rods or bolts bearing at one end against the lugs on the motoroasing, and disks on said rods or bolts against which the upper ends of said last-mentioned springs bear, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.

SIDNEY H. SHORT.
