CENTERING DEVICE.

Specification of Letters Patent.

Application filed August 31, 1911. Serial No. 646,999.

To all whom it may concern:

lie it known that I, VINION Id. SISSUN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Centering Devices, of which the following is a specification.

My invention relates to railway car construction, particularly to the form and arrangement of the striking-casting and drawbar centering device for freight ears, but is applicable to other *ars as well, and comprises certain improvements in these parts whereby a quicker and more positive drawbar centering action is obtained and weak parts of the structure are relieved from undue strain.

My invention further comprises certain details of construction of the car end framing and striking-casting whereby the ill effects of endwise shifting of the lading are largely overcome and there results a simple and strong structure to resist the heavy shocks which these parts have to sustain in service.

Further details of my invention appear in connection with the description of the embodiment thereof illustrated in the acconlpanying drawings forming a part of this specification, and are particularly pointed out in the claims.

Applicants co-pending applications Serial Nos. 046998 and 047000, for improvements in centering devices and car end framing, respectively, filed conciu'rently here with, contain claims for subject-matter shown, but not claimed, herein.

In the drawings, in which like characters are used to designate like parts wherever they occur-Figure 1 is a view of a portion of the end framing of a car showing the strikingcasting and draw-bar centering device in elevation, the location of the drawbar being indicated by dot and dash lines; Fig. 2 is a top plan view of the same partly in section on the line 2-2 in Fig. 1, the end sill being removed; Fig. 3 is a transverse section through the sill on the line 3 3 in Fig. 1; and Fig. 4 is a similar sectional view on the line 44 in Fig. 1.

In the portion of the end framing of a car illustrated in the drawings, the end sill I, is a solid timber, upon which rests the lower ends of the end posts 2, also of wood.

These end posts may be mortised into the end sill, but I prefer to secure the lower ends without cutting into the timber as here inafter described. The end sill rests upon the ends of the draft sills 3, 3, which extend the full length of the car and to which the draft rigging and draw-bars at either end are attached. The striking-casting 4, is secured to the ends of the draft sills by the angles 0. 0, riveted thereto, and by the flanges 7, 7, extending from the depending arms 9, 9, back parallel with the draft sills and securely bolted thereto. The strikingcasting is secured to the end sill by the trus rods 5, 5, extending from end to end of the car, and bearing upon the striking-castings at either end through the nuts 8. The end posts 2 are secured to the striking-casting directly by means of the lugs 10 to whirl they are bolted. This arrangement providcS a solid abutment for the outer sides of the end posts, and precludes the latter being forced out by the lading in the car shifting in case of sudden changes in the speed of the car. as might be the case were they merely let into notches in the end sill, or bolted to it. Moreover, my method of construction is cheaper to build and avoids weakening the end sill by cutting into it.

The carry-iron 1] for the draw-bar is arranged to be partly embraced at its ends by the bifurcated arms 9 of the striking-east.- ing, and is pivotally suspended by the links 12, swung from trunnions 13 having their support in bearings 14 in the striking-cast ing. The distance between these bearings 14 greater than the distance between the pins 15 connecting the links to the carryiron, so the links do not swing parallel with each other but are slightly inclined toward each other at the bottom. This arrange ment of links gives a quicker action to the device, that is, it results in the carry-iron be ing returned more quickly by the force of gravity to the central position after being moved therefrom.

The pins 15 are secured in the ends of the carry-iron by means of split cotter-pins, which may be removed without difficulty. The ends of the pins 15 project beyond the carry-iron and under the arc-shaped terminations 16 of the outer bifurcations of the arms 9, thereby preventing the links 12 from jumping out of their hearings in the striking-casting. To assemble the draw-bar in Patented Dec. 9, 1913/ the centering device it. is not necessary to slip it in from the end, a diflicult undertaking under some circumstam'es, but by removing one of the pins 15 the carry-iron may be dropped out of the way and the draw-bar inserted or removed vertically.

The upper surface of the carry-iron is made slightly convex, as shown at 17, in order to give a better bearing for the draw-bar when the carry-iron is swung in mid position than would be the case were the carryiron straight,'as in the latter case with the inclined link arrangement the carry-iron would take a slight. slant, and the draw-bar would either bear only at a corner or it would be slightly rotated on its axis to correspond to the slant of the carryiron.

It is evident that the inclined links 12 might be arranged in other ways than that shown in the drawings and, so long as they are somewhat inclined to each other, the quick return action would not be materially atfected.

I do not wish to be limited to the precise forms and arrangement of parts as above described, but what I desire to secure by Letters Patent is the equivalent of the form and arrangement of parts as above set forth.

I claim 1. A carrier for draw-bars, said carrier comprising members pivotally supported at the ends by trunnions and positioned obliquely, a draw-bar support carried thereby for swinging movement, and lugs on said draw-bar support which are adapted to slidably engage with fixed portions of the car.

2. In a carrier for draw-bars, a member fixed at the end the car, a carry-iron pivotally supported at each end to said member by links positioned obliquely, said carry-iron slidably engaging in notches provided in said member.

3. In a centering device for draw-bars, a carry-iron having end bifurcations and a middle portion adapted to support a draw bar, supporting members mounted in said end bifurcations and axially pivoted at fixed points of support on the car to swing transversely thereof, said fixed points being spaced equi-distant from the center line of the car and at a total distance apart different from the length of the carry-iron between its points of support.

4. In a centering device for draw-bars, a carry-iron having end bearings and a middle portion adapted to support a draw-bar, supporting members having ends pivotally mounted in said end bearings and journaled at the opposite ends in bearings fixed on the car, said last mentioned bearings being at a greater distance apart than the distance between the end bearings of the carry-iron so said supporting members are inclined inwardly in their normal position.

5. In a car, the combination of d'raft sills, a member connecting said draft sills and provided with depending portions, a carryiron pivotally suspended from said member and slidably engaging said depending portions, said carry-iron comprising a convex part adapted to support a drawbar, and said carry -iron suspending means yieldingly holding said convex part in central alinement with the center line of the car.

6. In a centering device for draw-bars, a movable carry-iron adapted to support a draw-bar, links pivotally mounted on the car and attached to said carry-iron by pins, said pins being adapted to engage with fixed portions of the car to prevent upward dis placement of the carry-iron in all positions thereof.

7. In a centering device for draw-bars, a carry-iron provided with means for centrally supporting a draw-bar thereon, links provided with trunnions pivoted to the ends of said carry-iron, said trunnions being mounted in bearings on a member rigidly attached to the frame of the car, and means associated with said links to prevent the trunnions from jumping out of their bearings when in assembled position.

Signed at St. Louis, Missouri, this 28th day of August, 1911.
