DRAW-BAR CARRIER AND EACE-PLATE.
SPECIFICATION forming part of Letters Patent No. 487,779, dated December 13, 1892.
Application iiled September 28, 1892. Serial No. 447.111. (No model.)
To aZZ whom it may concern,.-
Be it known that I, CHARLES T. SCHOEN, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Railway-Car Draw-Bar Carriers and Face-Plates, of which the following is a full, clear, and exact description.
This invention relates to the metal facings employed in connection with the front sill, draw-timbers, and draw-bar of railway-cars.
The invention consists of a face-plate for the front sill adjacent to the draw-head or coupling, a stirrup for the draw-bar, a chaiingplate .for such draw-bar, and countersunk washers for the reception of the truss-rods and their nuts, all made in asingle piece and fastened in position by the truss-rods and their nuts and the vertical bolts used to unite the draw-timbers and the front sill in ordinary freight-car construction.
The invention also consists in a renewable wear-plate laid on the stirrup, which takes the wear from the stirrup and is readily removed and replaced when neccessary.
In the accompanying drawings, illustrating my invention, in the several figures of which like parts are similarly designated, Figure l is a front elevation; Fig. 2, a side elevation, and Fig. 3.a vertical section taken through the center of the draw-bar opening.
a designates the usual front sill, and Z) the usual draw-timbers, of a freight-car. Now my invention is applied to these timbers irnmediately adjacent to the draw-head or coupling; and it consists of a face-plate c applied to the front sill a and covering the ends of the draw-timbers b. The stirrup d is formed on the face-plate as a rearwardly-projecting bottom ange, and the chaiing-plate e is constructed by punching or pressing back on three sides the metal of the tace-plate to form the draw-bar opening f, and the countersunk washers or cups g are made in that portion of the face-plate designed to be applied to the front sill for the reception Vof the ends of the truss-rods h and their nuts t'.
In order to stiften the face-plate, I prefer to provide it with an outwardly or inwardly projecting cross-rib 7 ,which may extend from washer to washer, as shown, or be located elsewhere, as the requirements of service may demand. The sides Z of the face-plate are flanged rearwardly to protect the outside corners of the timbers b and to assistin sustaining the stirrup. A wear-plate m is laid upon the stirrup to protect it against the excessive wear at this point consequent uponthe use and motion of the draw-bar, and this wearplate may be renewed easily and at slight cost at pleasure.
The device is applied to the car by means of the usual bolts n used to connect the sill a and timbers Z) and the truss-rods h and their nuts c', and no additional fastenings are necessary ordinarily. The adjacent sides of the drawtimbers may be notched to receive the chat'- ing-plate. By this construction the force of lateral concussion in coupling on curves is transmitted tothe truss-rods, andthis, together with the side anges Z, greatly reduces theliability of splitting the draw-timbers from suoli concussion.
In a common construction there are five separate and distinct parts used which I have united in one structure by my invention, and each of these several old parts requires its own individual fastening. The advantages in makingthe several partsintegral are many; but it will suttice to say that they may thus be applied by fastenings common to all, and hence at much less expense tor time and labor, and, moreover, they serve, mutally, to snpport and stiften one another, and, finally, the cost of production is considerably reduced.
While my device comprises in one piece or structure a face-plate, a stirrup, a chaiing plate, and washers for the truss-rods, for conciseness I refer to it as a draw-bar carrier and face-plate, meaning only to condense and simplify the title, without thereby putting a limitation upon the structure meant thereby.
My combined draw-bar carrier and faceplate may be die-shaped or pressed from sheet or plate steel or iron or other suitable metal, or may be produced in any other wayas, for example, it might be a casting, malleable or other kind. While I think the best results will follow from the use of steel in plate or sheet form shaped by dies or other machinery, I do not limit my invention thereto.
Vhat I claim isl. A draw-bar carrier and face-plate for railway-cars, comprising in a singlestrncture a face-plate, astirrnp, a chang-plate, and countersnnk washers for the reception of the trussrods, substantially as described.
2. A draw-bar carrier and face-plate for railway-cars, comprising in a single'structure a face-plate extending crosswise of the front sill and downwardly over the ends of the draw-timbers and having an opening for the draw-bar provided with a ohatng-plate and a stirrup made as a rearwardly-projecting fiange at the bottom of the face-plate, substantially as described.
3. A draw-bar carrier and face-plate forrailway-oars, comprising in a single structure a face-plate having countersunlr` washers `for the reception of the ends of the trussrods and their nuts, 'a longitudinal ribon said plate to stien it, a chafing-plate surrounding three sides of the draw-bar opening in said face-platdand a stirrup, substantially as described.
4. 'A draw-bar carrier and face-plate for railfdraw-tinnbrs and having an opening for the draw-bar, a chatting-plate projecting rearwardly from such opening, and a stirrnp, substantially as'desoribed.
In testimony whereof I- have 4hereunto set my hand this 27th day of September, A. D. 1892.
