CUSHION FOR LOG-CARRIAGES.

SPECIFICATION forming part of Letters Patent No. 760,854, dated May 24, 1904. Application filed January '11, 1904. Serial No. 188,479. (No model.

To all whom it may concern..- 1

Be it known that I, HERMANN Gr. DI'ITBEN- NER, a citizen of the United States of America, residing at Minneapolis, in the county of.

Hennepin and State of Minnesota, have invented certainnew and useful Improvements in Cushions for Log-Carriages; and I do here.- by declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention is especially directed to an improved arrangement of cushions for customary to arrange a cushion at each end of the track on which the carriage moves in such position that they will engage the central portions of the transverse end timbers. With this arrangement the great strain thrown upon the engagedtransver'se end timbers has in practice frequently broken the same, and sometimes when not broken they have been known to yield and permit the carriage to jump over the cushion, thus doing all sorts of damage.

In accordance with my invention I arrange the cushions 1n'pa1rs and secure the same in such positions that one will be directly engaged by the end of each alined side beam of 5 secured to heavy floor-timbers 2.

Of the parts of the carriage it is only necessary to note the wheels 3, axles 4, and the frame made up of the longitudinally-extended side beams 5 and transverse end timbers 6.

The cushions, which may be of any approved form, are preferably made up of cylinders or dash-pots 7 and pistons 8, the stems of which project for contact with the ends of the side beams 5. These cylinders or dash-pots 7 are, as shown, rigidly secured to heavy transverse timbers 9, that are rigidly secured to the ends of the timbers 2. It will be noted that the cushions are. located with their axes directly in line with the side beams 5 of the carriage, so that the projecting ends of the said beams at a given end of the carriage will simultaneously be thrown into engagement with the projecting ends of the stems of the pistons 8 for an important purpose, which has already been stated. By the statement that the ends of the beams 5 directly engage the ends of the piston-stems it is not meant that the ends of the Wooden bodies of the said beams actually contact with the ends of the piston-stems, for, on the contrary, in practice the ends of the said beams would advisably be faced with metal caps to prevent the same from being split or pounded out of shape.

The gist of this invention is found in the arrangement of the cushion with respect to the carriage so that all strains put upon the carriage when 'the same is run against the cushions are resisted by an endwise thrust or blow received directly in line with the side beams of the carriage.

What I claim, and desire to secure by Let ters Patent of the United States, is as follows:

The combinationwith a track and a carriage movable over the same, saidmarriage having longitudinally-extended side beams, of a pair of cushions anchored with respect to the track and located one in line with each side beam of said carriage, whereby strains,

in stopping the carriage, are received directly by and endwise of the said side beams, substantially as described.

In testimony whereof I have affixed my signature in presence of two witnesses.
