DEVlCE FOR SUPPORTING BODIES OF VEHICLES.

SPECIFICATION forming part of Letters Patent NO.) 623,787, dated April 25, 1899. Application filed December 29, 1897. Serial N07664:,3'71t (N0 model.)

To all whom it may concern:

Be it known thatLJoHANAUeUsT J ANSSON, a subject of the King of Sweden and Norway,- and a resident of Hagalund, Stockholm, in the Kingdom of Sweden, have invented certain new and useful Improvements in Equalizing Devices for Supporting the Bodies of Vehicles, of which the following is a specification.

This invention relates to the class of devices for supporting the bodies of vehicles-such as railway-cars,wagons, carriages, and sledgeswherein equalizing levers and springs are employed between the axles and the vehiclebody to cause the latter to move up and down parallel with itself as the load varies and to m aiutain the body substantially parallel with the road-bed when the load is unequally distributed.

In the construction herein shown the pairs of equalizing-levers are fulcrumed under the vehicle-body, the levers of the pair being situated near the respective sides of the vehicle and their inner arms being bent inward so as to meet near or at the longitudinal axis of the vehicle, where they take either directly or through an intermediate lever under a transverse spring secured to the body substantially at the middle of its length. In the form employed for ordinary streetcars and wagons the pairs of levers are fulcrumed on the respective axles and their inner longer arms take directly under the spring; but in long railway-cars having bogie-trucks the pairs of levers are fulcrumed on the car-body and there are intermediate levers to take under the spring or pair of springs.

In the accompanying drawings several embodiments of the invention are illustrated.

Figures 1, '2, and 3 are respectively a crosssection, a side elevation, and a plan of a relatively short railway-car provided with this invention. Figs. 4, 5, and 6 are respectively of a longer railway-car provided with this invention. Figs. 7, 8, and 9 are respectively an end elevation, a side elevation, and aplan of a wagon having this invention applied thereto.

Referring primarily to Figs. 1, 2, and 3, it will be seen that underneath the car-body there are four levers arranged in pairs, the

levers of the pairs being under opposite sides of the body. The shorter outer arms of these levers are designated by A and the longer in ner. arms by B. The levers are fulcrumed on the car-axle, their shorter arms extending out under the ends of the car and coupled to a cross-bar or shaft D, mounted in brackets under the car-body O. The longer arms B of the pair of levers are bent inward to the longitudinal axis of the car and where they are secured together. The pairs of levers are coupled together at the middle of the length of the car-body by a pin E. A strong spring F is placed transversely under the car-body -bet-ween said body and the coupled ends of the pairs of levers. This spring is coupled to the car-body at its ends, preferably by links, and it is supported at its middle on the links at the coupling-point E. As the axles of the cars are always at a fixed elevation and form the f ulcru ms of the pairs of levers and the inner ends of the levers are coupled together, it will be evident that any depression of the body at one point will be equallydistributed over the whole body. The ratio between the arms of the levers can be conveniently taken as one to two, thus making the weight on the spring equal to one-third of that of the load.

Figs. 45, 5, and 6 represent the application of the invention to what is called a bogiecar. In this construction the pairs of levers H have their outer arms coupled to the bogietruck, are fulcrumed on the car-body, and have their inner arms brought by bending into the longitudinal axis of the car and coupled to the outer end of an intermediate lever I. This lever is fulcrumed on the carbody, and the inner ends of the two levers I take under springs K, interposed between them and the body of the car.

Figs. 7, 8, and 9 show an ordinary fourwheeled wagon to which this invention is applied. The system of levers shown in these views is substantially the same as that seen in Figs. 1, 2, and 3. The pairs of levers are not, however, fnlcru med directly on the axles, but on a frame L, mounted on the axles. This frame is pivotally attached to the rear axle, as seenat L in Fig. 7. The leading feature of this invention consists in bringing the two levers of the pair inward substantially to the longitudinal axis of the vehicle and supporting the transverse spring at the middle of the body directly or indirectly on the levers at the axis of the car.

'lhree applications of the invention have been illustrated herein; but it will be obvious that the construction may be varied to suit other applications without departing materially from the invention.

Having thus described my invention, I claim- 1. The combination with the wheels, axle and body of a vehicle, and a transverse spring situated under said body, of levers extending lengthwise of the vehicle and fulcrumed under the body at its respective sides, the arms of said levers at one side of the fulcrum being bent inward to the longitudinal axis of the body and coupled to said transverse spring, whereby the latter is interposed between said levers and the body, substantially as set forth.

2. The combination with the wheels, axles and body of a vehicle, and a transverse spring situated under the middle of said body, of two pairs of levers under the ends of the vehiclebody, the levers of each pair being fulcrumed under the body at its respective sides and the inner arms of the levers of the pair bent inward and connected together substantially in the longitudinal axis of the vehicle, said inner arms being adapted to exert an upward pressure on the center of said spring when a load is put on the vehicle-body, substantially as set forth.

3. The combination with the wheels, axles and body of a vehicle, and a transverse spring situated under the middle of said body, of two pairs of levers under the ends of the vehicle-body, the levers of each pair being fulcrumed under the body at its respective sides and the inner arms of the levers of the pair bent inward and connected together substantially in the longitudinal axis of the vehicle under said spring, whereby when the vehicle is loaded, the spring will be compressed between the said levers and the body, substantially as set forth.

4. The combination with the Wheels, axles and body of a vehicle, and a transverse spring F, under the body at the middle of its length and connected thereto at its ends, of two pairs of levers, fulcrumed on the respective axles of the vehicle, the shorter arms, A, of the levers extending out under the respective ends of the said body and coupled thereto and the longer arms, B, of the levers of the pair bent inward and connected together, the inner arms of the levers taking under the middle of the transverse spring, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

JOHAN AUGUST JANSSON.
