Applieation'lilcd May 25, 1885.
" which the following is a specification.
of propellingjthe same; and my object is to Apole-pieces h h of the lieldmag'net. The
My invention rela-tes to electric motors mounted upon railwaycars for the purpose so arrange and support the motor that the relative. positions of the armature and eldmagnet ofthe motor will not be changed, and the mechanical connections between the armature and the driving-axle will not be disturbed by any movement of the car-body on its springs at thc same time that the drivingaxle will be relieved ofdead-weight.
My invention is illustrated in the accompan yin g drawings, in which- Figure l is a plan view of an electric railway-motor einbod yin g said invention and employing a coggearing between the armature and drivingwvlieels; Fig. 2, a-section ofathe truck with the electric motor in elevation; Fig. 3, a view, similar to Fig. l, of a motor employing a rictiongearing; and Fig. 4, a view, similar to Fig. 2, of this motor. l
Referring iirst to Figs. l and 2, A is the frame of the truck of a railwaycar, and B B and B B are the wheels of the same. The truck-body is supported from the axles C C i through springs, in any usual manner.` D is the field-magnet of an electro dynamic motor, and E the armature thereof. The yoke or back piece, a., ofthe field-magnet is hung from a cross-piece, F, of the truck by heavy springs lb b, or from the car-body itself in case of a streetcar or other vehicle having no truck. The driving-axle C at its middle portion is inclosed in journals cc, situated be tween collars (l l on the axle, and thesejournais are held by clamping parts ce, joined to gether on one side of the axle by a plate, j', to which they are bolted, and on the other sde bolted to extended parts g gfromfthe clampingpieces e c are ot' noninagnetic metal. The bearings i t of the armaturelshat't are carried directly upon the ficld-magnet polepieces, bein supported by arms lc k, attached to the journal-boxes and said pole-pieces. Upon thc inner side of each of the driving ,i rection (No model.)
wheels is a cog-gear wheel, Z, which may be made in one piece with the Wheel, but is preterably `made itself in two parts, bolted or otherwise removablyattached to the wheel; or, whether made in one or two parts, it may be secured directly to the driving-axle. Upon each end of the arinaturelsh aft is a cog-wheel,
, m, and these engage, reslfiectively, with the cogsurfaces ot' the,driving-wheels, and thus communicate motion to said wheels to propel the car when the armature is revolved. I rlhe armature being carried rigidly by the field-magnet, these two parts must always maintain precisely the same relative position under every vertical or lateral movement of the wheels or ot the car-body; and as the fieldmagnet which carries the armature is .itself centered by the axle of the wheels to which the armature-shaft is geared, the engaging gears also must always maintain precisely the same rela-tive position. At the same time the connection of the entire motor with fthe truck is through springs, so that its position is not affected by the movements ot the truck on its springs.
G and Gr` are eontactrollers ruiming' on the intermediate rail, K. Each contact-roller has bearings between the ends ofthe curved arms H H,pivoted at a between supports 0 o, extendin down from the ear, and having a spring, p, attached to the other end, connectingitwith the car-body, whereby the rolleris constantly' maintained in good contact with thcintermediate rail, K, which forms one side ot' the suppl yin circuit. Theother side of thecirenit is toi-ined by the working-rails L L and the ground. In the form shownin Figs. 3 and 4., friction-gears are used lbetween the armature and driving wheels instead of cog gears, as before.
I I are friction-surfaces attached to the driving-wheels or the driving-axle, and .I J are friction-wheels engaging therewith on the armature-shaft. Means are provided for adj listing the contact of the friction-surfaces. A screw, r, passes through the plate f, and sets against a plate, s, situated in contact with the journal-boxes in such manner that when the screw is turned, as the plate s cannot move the plate j', clamping parts c o and the iieldmagnet and armature are drawn in one dithe other, and the frictiongears are thus .i'iusterh A similar device is shown in IOO Fgs. l and 2 for adjusting the coggcars, if necessary.
'It' is evident that any other form of gearing may be employedas belts or friction-clutch- 5 es-s the relative position of the axle'and springs extend to cross-bars on truck-frame,
or to the car-body in cas no truck is used.
locked by other nuts, u. v This adjustment may be such as to carry wholly or partly the Weight of this end of the motor, or so as to actually exert a pressure upon the lower side of the drivingaxle. y By this feature of the invention the `hammering effect which Would result from supporting the motor directly upon the axle will be reduced to the minimum.
lhat I claim isl. The combination of a Wheeled vehicle and an electro-dynamic motor mounted thereon and propelling` the same, having its Iieldmagnet sleeved ena-n axle of the vehicle, substantially as set forth.
2. The combination ofa wheeled vehicle and van electro-dynamic motor mounted upon and propelling the same, the field-magnet of said vmotor being sleeved upon an axle of the vehicle at one end, and supported by flexible vconnections from the body of the vehicle at the other end, substantially as set forth.
3. The combination of a wheeled vehicle, an electro-dynamic motor mounted upon and propelling the same, and flexible connections be- 45 tween the tield-magnet of the motor and the body of the vehicle, the armature of the motor being supported directly upon said field magnet, substantially as set forth.
Their tension is adjusted by nuts t, which are 4. rlhe combination of a wheeled vehicle, a i electrodynamic motor mounted upon and propellingthe same, the tieldmagnet of said 111e-, tor being sleeved upon an axle of the vehiclt, and the armature of said motor beingsup ported upon the lield-magnet, and gearing between the armature-shaft and the drivin wheels of the vehicle,substantially as set fort 5.

supported upon. its axles by springs, of aneleetro-dynamic motor flexibly supported from' such vehicle, and vcentered -upon the drivingaxle thereof, substantially as set forth.
7. The combination, with a wheeled vehicle, of an electro-dynamic motor centered upon the drivingaxle thereof, and havingits armatureshai't imparting motion to such axle, and a spring-support for the motor, relieving said axle wholly or partly of the deadwveight of motor, substantially as set forth.
- S. 'lhe combination, with a Wheeled vehicle, of an electro dynamic motor, centered upon the drivingaxle thereof, and having its armatureshat't imparting motion to such axle, and an adjustable spring-support for the motor,`relievin g said axle Wholly or partly of the deadwveight of motor, substantially as set tertn. Y
9. The combination, with a Wheeled vehicle, of an electro-dynamic me or centered upon the 1/drivil'ig-axle thereofat one end, a springsupport for that end of the-motor from the truck or body of vehicle, and relieving axle Wholly or partly of dead-Weight, and a spring` support for the other end of motor from the truck or' body of vehicle, substantially as set forth.
