DRAW-BAR CARRY-IRON.

T 0 all 'whom it may concern .f

Be it known that I, EUGENE H. CROWN, a citizen of the United States, residing at city o-f Sacramento, county of Sacramento, State of California, have invented a certain new y and useful Improvement in Draw Bar Carry-Irons, lof which the following is a full, clear, and exact description, such as will enable others .skilledin the art to whichl it appertains to make.v and .use the same, ref

erence being had to the accompanying draw- 5' ings, forming part -of this specification, in

"l11(`3l1-A v -Figure 1 is a front elevational View of a railway car striking plate and showing my improved. carry iron applied thereto. Fig'. '42 is a vertical section taken on the "line 2-2 of Fig. 1. Fig. 3 is a horizontal section taken approximately on the line 3 3. of Fig. 1. Fig. 4 is a perspective view of my improved carry iron with the roller removed.

My invention relates to new and improved carryingmeans forxthe draw bar of car couplers, the-principal object of my invention being to provide a lreversible bar or carrying member, and to combine therewith a roller which has a certain amount of backward and. forward movement upon the supporting bar, and Whichroller'supports the draw bar, thereby reducing to a minimum the friction. between the support and thel draw bar, as the latter moves-lengthwise as a result of pulling and buling strains.

A further object of my inventionis to provide a rolling support for draw bars which 'can be adjusted vertically so asto vary the height at which the drawpbaris carried.

with the above and other bjeas in. View,

my invention consists in certain novel features of construction and' arrangement of parts, hereinafter more fully described and claimed. y Referring by numerals to the accompanyingdrawings, 1 designates a strikingplate-A which is applied in the usual mannerto the car end sill or buffer beam, and formed integral with or iXed to this striking plate are depending brackets 2, the lower ends of which are bifurcated'lso as to receive the ends of my improved carry iron. The walls of one ofthese brackets are provided on their inner faceswith substantially U-shaped seats 3 which are adapted to receive trun- Specification of'lLetters Patent.

nions formed on one end of my improved carry. iron and the walls' of the lopposite bracket are perforated to' receive a pin or bolt.

The main body of :ny-'improved carry iron comprises a block 4, which is approximately rectangular in cross section and provided in its top and bottom faces with longitudinally disposed grooves or depressions 5. Formed integral with the endsv of this block are heads 6 which are adapted to fit snugly between the Walls at theI bifurcated lower ends of the brackets 2, and formed integral with the headat one end ofthe block are trunnions 7 which, when the carry iron'is 1 properly positioned for use, pccupy the seats 3. Formed' through the opposite head 6 is an aperture 8 which, when the carry iron is positioned f'orjuse, coincides with theV apertures formedI through1the walls` of .one of the vbrackets 2, and positioned in theseaper-l' tures is a lock-ing pin or bolt 9. .The carry v iron is formed vso'that the .bottom 4surfaces of the grooves or `recesses 5 are located at diHerent distancesfrom a horizontal line' Vdrawn through the centers of the trunnions 7 `and the lockingfpin 9, and thus, by reversingthe carry iron, the height at which the supported draw bar is carried'can be.

varied.

yLooselyV mounted inthe -groove or recess on top of the block l4 is a roller 1'0, the ends of which normally occupy posit-ions between 'the walls at the lower ends of the brackets 2. Thevshoulders 6a formed between the heads 6 and the block 4 holds the roller 10 against yl ongitudinall movement, but said roller is free to rollbackward and forward upon the block 4., thus forming a rolling support for the'diaw' bar and reducin0r the friction.v between said draw bar and support asthe draw bar is moved` lengthwise under pulling and buffing strains.4

The backward and forward 'movement of the roller 10 is limited by the ribs'orflanges at the sides of they grooves 5, and as the ends of saidroller project between the walls at the lower ends of the brackets 2, said roller l is'prevented from becoming accidentally displaced from theblock 4, asa result of blows or jars which may be received by the carry iron or striking plate.

.By my improved construction of carryiron, a free rolling support is provided fo-r the supported draw bar, the movement of which rolling support is lengthwise of the car, and in the same direction as the pulling and bufiing movements imparted to the draw bar. For this reason the friction between the draw bar and its support is reduced to a minimum. i

By making the Block et reversible, and forming the bottoms of the groove-s or Arecesses at different distances from the horizontal center of said block the height at which the supported draw bar is carried may be variedv or adjusted.

It will bereadily understood that minor changes in theI size, form and construction of the various parts ot' my improved draw bar carry' iron may be made and. substituted for those herein shown and described, without departing from the spirit of my invention, the scope of whichis set forth in the appended claims.

I claim: g

1. The hereindescrbed carry iron comprising an elongatedmember provided with. a plurality of longitudinally disposed grooves, the faces of which are arranged at.

different distances from the horizontal center of said member, a roller loosely mounted in the uppermost one of said grooves, shoulders at the ends of said grooves for holding the roller against longitudinal movement, and ears on the ends hof said member, which ears are adapted to be secured to suitable supports.

2. The hereindescribed carry iron coinprising an elongated member kprovided with a plurality ofroll'er seats'arranged -at different distances from its horizontal center, whereby the elevation of the uppermost seat can be varied by reversingthe carry iron, a roller loosely mounted on the uppermost seat, and ears on the ends of said carry iron, portions of which ears serve as shoulders to hold the roller against llongitudinal movement.

In testimony whereof, I hereunto aflix my signature in the presence of two Witnesses, this 21st day of February, 1914.

EUGENE H. CROWN.
