To all in am it may concern: 1

Be it known that I, W. BRITTON LAnn, a citizen or the United States, and a resident of Evanston, in the county of Cook and State of Illinois,' have invented a certain new and useful Improvement in Cushioning Means for Railway-Cars, of which the following is a description, reference being had to the accompanying drawing, which formsapart of my specification. v t

My invention relates more particularly to means whereby a pneumatic cushion will be provided for railways'cars, the means being so constructed that the elastic medium or 18 air may be supplied by the usual air line of the train.

The object of the invention is the provision of means whereby an easier riding car is produced, which will be practically free of the shocks and vibration encountered where the usual truck springs alone are employed; and whereby the lateral swaying of the car due to unevenness in the road bed will be practically eliminated through the 5 absorption of the motion by the cushioning means mounted on opposite sides of the car. thereby also greatly relieving the rails and ties from the shocks and stresses to which v they are subjected with the present existing 0 constructions.

In the drawings :.-Figure 1 is a cross secconnection with the type of truck and car bod at present in use.

The invention consists in providing one ormore cylinders 10 at both, sides of the car ody at points coincident with the trucks. so The side walls of the cylinders may be provided with the flanges 11, 11, which are" adapted to extend beneath the adjacentlongitudinal sills 5 and secured thereto in any suitable manner as illustrated for example in Fig. 1. The cylinder 10 is preferably provided at a suitable point intermediate of its ends with an escape port or opening 12, see Fig. 2, while the side of the cylinder facing lengthwise of the car is preferablyvo provided with a valve chamber 13, which is connected with the conduit or pipe 14 which connects with the usual air line of the car. The valve chamber has communication with the cylinder interior rough the port 15. The chamber 13 is provided with a suitable sliding valve as shown at 16 adapted to move in a vertical direction therein.

Cylinder 10, which is shown with its lower end open, is provided with a suitable piston 17. The piston 1'1 is adapted to be secured to or rest on the ends of the car bolster 7 as shown in Fig. 1. The piston 17 is pro vided with suitable packing rings or glands 18 so as to provide an air tight sliding con- 35 tion.

Fig. 3 is a horizontal sectional view taken on the line 3-3 of Fig. 2. Fig. 4 is a detail view showing 49 the valve mechanism in perspective.

In the drawing and Fig. 1, 5 represents the usual longitudinal sills of the car arranged beneath the floor 6,, with my improved cushioning means shown a plied be- 5 tween the two longitudinal side SlllS of the car at opposite sides thereof; the device being preferably arranged intermediate of the longitudinal sills of the car and the car bolster 7, which latter is mounted above the 59 truck bolster 8, with the usual center bear- 111 9 arranged between the two bolsters.

As my invention does not relate to the description of the trukwill not. be entered as the inventipnis adapted foruse in construction of the truck or car," a specific of Fig. 1 looking inthat valve 16 chamber 13 until air has entered cylinder 10 I and forced the piston.

nection between the piston and the walls of the cylinders. The piston 17 is provided with an extension or lug 19 which has a suitable opening to receive the stem 20 of valve 16. In the drawing, this stem 20 is .shown screw threaded to receive nuts 21, whereby therelation between the piston and the valve may be controlled:

In the application of my invention, one

or more cylinders are arranged between the longitudinal sills of the car body at points preferably above the ends of the car bolster; the cylinders being secured to the longitudinal sills as previously 'described, while the pistons are placed on the ends of the car bolster, and if desired, may be secured thereto. The valve chamber 13 is then connected with the air line of the train by means of pipe 14, so 13 and be. allowed to pass into cylinder 10, which is made possible by reas'on' of the fact will be in the upper'part ofconstruction shown in the 90 that air may flow into chamber "With the valve 16 in the pe the lifting or upward inevei'nent of the plligu 2, it is evident h ew )L pesil'e side of the car will close off the flow cylinder Wlll he she 01' 111" to the cylinders at that side of lhe inders 10 are filled wit f1; it is car -which above the norm all level so that '1 5 that iihe pistons 17 will he i eeced i 21 substantially uniform depth 01 air cushion 79 cylind until they in Contact will be iniiiniained. upper or end Well of the cylindew The l -xpuse 23 will permit the air to seep the pistons moved up inte this 0 1" I or pas hack into the air line 01"" the 'i'lfllll will be seen that the Valve 16 Wlli b CODA-- and thus prevent its eecape, all the same time w pelled to move upward in valve chamber "L relieving the pressure in the cylinders clur- 7:5
