Application lcd September 27,1918. Serial No. 122,520.

To all whom it may concern: 4 Beit 'known that I, OWEN T. Dono-Henry,

'a citizen of thellnited States, residing at St. 'Paul, in in malty of Ramsey and State of Minnebe., ave invented certain new and useful Improvements in Railway; of 4which the following is a specification.

This inventionA relates to railwayrar trucks, .and has for its object the production of a. truck structure comprising parts of special construction and whereby it 'is believed the up movements of the bolster or weight-supporting membev. of the truck are fully cushioned7 and, 'ut he Same time, the forward or rearward impulses or movements of the member arenyieldingly received by the springs.

and down when a car is started there are always several backward and foi-wurd shocks before the whole. moves evenly forward, and, -when a cai' is stopped there is always a final-and.

apparently rearward jolt as the body of the By the use of this invention the initial and final shocks are taken `up by suitably arranged si'ilrings', and. not

only is the car thus equipped rendered .more

pleasant to'r-ide upon, but its useful-life iS.

inateri ally increased.

ln the 'accompanying drawings, the parts y 0F this invention, theii` construction and re1- 'f downwardly and the axles aiul certain other shown in section. liig. is

all parts showing the manner in which the pull of the locomotive pauses. .the bolster to riseV upon the upwardly-curved portion of the frame and relieves the spi-ings in order that they may assist in supporting the load by their resilience'. l .I Throughout the description and drawings the same letter is used toreferto thefsume Considerin track A are t way truck of customay construction, and having the axles C, '0.

The truck axles are journaledin-suitable boxes carried bye frame D and the frame has an opening d in the middle of its length. Arranged in the opening'of the frame is a' head E of the bolster.e. It will be noted the head E conand against Athose sides verge downwardly,

Any suitable means such as the lugs Il and JL, may be provided to holdv the lower, ends of the springs' inthe opening: Z of-the frame D.

The momentum of the car bocy forward is abruptly opposed, and when trucks of ordinary construction and with which this applicantis acquainted are used, there is a' suceessionlof backward and spring G. larly taken up by the slring g. It is boecn made clear by forward shocks, alwaysunplcasunt to the occupants of the car. When this invention is used, themoinen'tui'n of the body forward 'presses the inclined side of the head or block j against the correspondinglincline of the collar J, and the shock is taken up by the Rearward impulses are similieved, therefore, to have the drawin andthe fore oing specification that t e -bolster is a equately. cashioned, by means of thetwo inclined coiled springs and the construction disclosed, for

sudden movements of any kind upor down,

forward or rearward. Attention is also' ofthe load.
