PATENT O FICE.

CHARLES J. VAN DEPOEIIJE, or LYNN,

MASSACHUSETTS.

MOTOR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 461,293, dated October 13, 1891. Application filed September 25,' 1839- Serial No. 325,011. (No model.)

To all whom it may concern:

Be it known that I, CHARLES J. VAN DE- POELE, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements which the following is a description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.-

My present invention relates to improvements in trucks for includes special provision in a car-truck for sustaining the propelling-motors in operative relation to the carrying or driving wheels thereof, as will appear.

A construction illustrating the invention will be hereinafter described, and referred to in the appended claims.

In the drawings, Figure 1. is a plan view of a motor-truck embodying myinvention. Fig. 2 is a side elevation also showing the motortruck and indicating in dotted lines a portion of the lower part of a car-body. Fig. 2 is a detail view of one of the estal omitted.

As indicated in the drawings, the carrying- Wheels A A and B B are sustained, respectively, upon axles a b, the extremities of which are mounted in journal-boxes a'a? b b The axle-boxes may be of any type or construction, and each is provided with strong lateral extensions or brackets 0 extending from both sides thereof. The axle-boxes, being mounted directly upon the ends of the axles of the carrying-wheels, form the points of support for the entire weight to be carried. Consequently if suitable springs .are interposed between said axle boxes and the superincumbent weight, spring effect will be secured. we of such springs are provided for each bearing, being indicatedin the drawings at D. The springs D are seated at their lower ends upon the bracketsC, and, as here shown, at their upper ends in a saddle E. The saddle and the springs are, furthermore, connected by Vertical rods 6, which pass from the saddle through the interior of the springs and through the brackets 0, extending downward therefrom to form supports for sills or framebars I", through which they-pass and below bearings with pedin Motor-Trucks, of

connected to and electric-motor cars and frames are sleeved upon strong transverse Additional further absorb vibration and prevent jarring.

The sides of the truckarejconnected by end bars G H, which extend around the ends of I their respective ends are 6c the truck and at secured upon the saddles E by bolts e, in addition to which the bolts e maybe extended thereth'rough. The c0nnection between the end bars G Hand the framebars may be reenforced and rendered still further secure by tie-bars g, which extend between the end bars G H, and are securely connected to the extremities of the frame-bars F. Theintroduction of the tie-bars 9 does not, however, affect the action of the truck, since the parts are primarily connected by the vertical bolts 6 and move as a unit under any circumstances.

The car-body is mounted'upon the end bars G H, one of the sills of the car-body beingind-icated in Fig. 2 in dotted lines. The bearing boxes a a b I), being sustained upon the extremities of the axles a b, will remain at a fixed distance from the rails. The car-body, be

ing sustained upon said axle-boxes by springs D, will have some vertical niovementthereon, in accordance with the stiffness of said spring and the inequalities of the roadway.

spring-supported parts, will move vertically therewith.

Electric motors I J are indicated in the drawings, together with suitable gearing, extending between the armature-shafts and the said axles a Z). The inner ends of the motorthe axles It]; by sleeved bearings z' 'i jj, and the special object of this in ention is to provide a strong, convenient, and durable support for the free ends of said motors, whereby they may be sustained in such manner that they may have some radial movement with respect to the axles, upon which their inner ends are sustained. This radial movement is necessary, in order to utilize the effect of cushioningsprings connected with their free extremities. This result is supports F F which are The frame-bars F, being suspended from the I00 attained by providingframe-bars Suitable springs are interposed between the transverse supporting-bars FQF and the outer ends of the motors, and said springs may be of any desired for mfor example, as indicated at K K 5 It will be understood thatI contemplate insnlating the springs K K from their. supports, if found desirable, and also that I may use any desired form of spring. The form here shown, however, gives good results.

. The actual connection between the motors and their snpportin g-sprin gs is, as here shown, in the form of a bracket k k, which is of dia-' magnetic metal and securely attached to the extremities of the field-magnets of the motors. This feature is, however, claimed in another application.

' mightLbe dispensed with and the transverse It will be evident that the brackets 70 70' supports F F be placed directly under the lowest portions of the ends of the motors, and that thereforedhe invention is not limited to theprecise details here shown, since goodresuits might be secured with other dispositions"of' the parts.-

The obvious advantage of the construction here shown is found in the fact that the cushioning efiect of both sets of springsviz., those supporting the car-body, together with the secondary frame, and those placed directly under the motors-is availed 'of' to modify the jarring and vibration incidentto the movements of the vehicle.

Having described my invention, what claim, anddesire to secure by Letters Patent thereon, is- I 1'. The combination of a spring-supported truck-frame adapted to sustain the car-body, a secondary frame depending therefrom, one or more motors sustained at one end upon the truck axle or axles independent of the springs, and yielding connections between the free ends of the motor or motors and the secondary frame.

2; The combination of a frame joining the pedestals of a car-truck and adapted. to receive the car-body, a separate frame depending from the main frame and also sustained by the springs supportingthe car-body, and

an electric motor having atone end a bearing 'upon the axle independent of either frame and at its other or free end a yielding sup- .port upon the depending frame.-

3. In anelectric-motor truck, the combination, with the axle-bearings, of springs sustained thereon, acar-body mounted upon said springs, a frame below the axles and sustained at its ends upon connections extendibng downwardly from the supports of the cary, upon the-axles with their free ends extending toward each other,-said free ends spring-supported upon the suspended frame.

' In testimony whereof I hereto affix my signature in presence of two witnesses,

CHARLES J. VAN DEPOELE.
