CAR-DOOR RIGGING.

Application filed .Tune 7, 1913.

Toall whom it may concern:

Be it known that I, RALPH V. SAGE, a c1tizen of the United States, residing in the borough of Vestmont, in the county of Cambria and State of Pennsylvanla, have 1nvented certain new and useful Improvegments in Car-Door Rigging; andI 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 appertainsto make and use the ,SELIDB.

" this in View, I rivet or otherwise secure directly to the bottom of the horizontal flange of each of the angle barstrengthening members which are attached along the lower inner side of the webs of the channel center sills, a short section of a rolled angle cut into the desired length and shape, with its longer leg member vertical and extending downwardly therefrom, the pair of angles being preferably arranged back to back. I

"also arrange the pair of angles quite close ing angles which I provide, however, pro- 'ject inwardly and are therefore close to Specification of Letters Patent.

Patented Feb. 8, 1916. Serial No. 772,232.

gether, and by securing my pair of perforated angles to said strengthening angles, thispair of perforated angles have their downwardly projecting portions close together forming a compact, simple and efficient bearing for the crank hubs which are journaled' therein.

As illustrated in the drawings, I have shown angle bar bracket bearings arranged with their outwardly extending horizontal flangesattached to the bottom of the inwardly extending horizontal flanges of the strengthening members of the center sills. In this way theangle bar bracket bearing sections have theirvertical webs disposed back to back and near enough together to allow the reduced ends of hub of the crank arm which is mounted on the inner end of the operating shaft to extend into the perforations provided therefor in the said angle bar bearing sections. By making these hearing members out of a rolled angle bar, a much cheaper, stronger and more rigid bearing bracket can be produced for the same amount of metal used, than'by forming them out of pressed or cast metal.

Another object of my invention in connection with the foregoing, is to reinforce and stifien the end of the connecting lever or link which is pivotally attached to the crank arm and adapted to swing over and beyond the operating shaft when the doors are closed, whereby the increased strength and weight will hold the doors more securely closed and prevent undue deflection of the bentend of said lever.

Having thus given a general description of my invention, I will now, in order to make the matter more clear, refer to the annexed one sheet of drawings forming part of this specification and in which like characters of reference indicate like parts.

Figure 1 is a vertical longitudinal'sectional elevation of a portion of a hopper bottom car taken on the line I--I of Fig. 2. Fig. 2 is a vertical transverse sectional elevation taken on the line II-II of Fig. 1 through the center of a car looking in the direction of the arrows. Fig. 3 is a detail side elevation showing a portion of a center sill and enough of the surrounding partsof the car to illustrate the position of my an- I locking-dog, also pivotally mounted on said bearing casting, by means of which the operating shaft is held in locked position when the door is closed. Fig. 5 is a vertical transverse section through the center of one of the angle bar bearing members, indicating in dotted lines. the cutaway portion of the horizontal leg.

Referring now to the various characters of reference on the drawings :-1 indicates the car door operating shaft having its outer bearing in a casting 2 riveted to the outside hopper sheet 3 and its inner end and intermediate portions supported by bearings 4 and 5 respectively, which are preferably cut from a rolled angle bar into the desired lengths. These angle bearing members 4 and 5 have their horizontal legs 6 riveted or bolted to the bottom flange of the angle bar strengthening member 7, which is attached to the inner face of the web of each of the channel center sills 8 near the bottom edge thereof. The angle bearing members 4 and 5 have their vertical legs 9 disposed back to back and are perforated centrally as at 10,

in which perforations are journaled the reduced ends 11 of the hub 12, which is mounted. on the squared inner end of the operat- 1 ing shaft 1, on which shaft is secured the crank arm 18. The outer end of said crank arm 13 is bifurcated as at 14 to receive the upper enlarged curved end 15 of the lever or connecting link 16 which is pivoted thereto by means of a pin 17 while the opposite end of the link 16 is pivotally attached to the door spreader bar 18 by means of the eye bolt 19 provided with a pivot pin 20.

The outer end of the operating shaft 1 which is journaled in the casting 2 on the outside hopper sheet 3 extends beyond the same and is squared as shown at 21 to reufactured out of rolled stock material by.

shearing the same into the desired lengths, the edges of said lengths being cut on a bias, or diagonally inward from the horizontal attaching leg toward the center of the outer edge of the leg, whereby all surplus material is cut away, then punching the desired perforations therein and a portion of the horizontal leg cut off as indicated in dotted lines in Fig. 5 of the drawings... In forming these bearing members in this shape, a considerable saving in weight is obtained, with out impairing their rigidity or strength. The peculiar formation of the curved upper end 15 of the connecting link 16, which is thrown over the shaft as the doors are closed, insures that the doors will remain closed, even if the locking mechanism at the outer end of the shaft becomes disarranged,

as the increased weight and stiffness of said 1 end will hold it in place as shown in Fig. 1.

The shape and general conformation of the curved end 15 of the connecting link let is such that when the doors are closed, the line of pull from the doors, which extends from the center of the pivot pin 17 to the center of the pivot 20, passes below the shaft 1,

so that a pull from the door, tending to open the same by swinging it downwardly, will not open said door, but will cause the connecting link 14 to press downwardly more firmly against the hub of the crank arm 18,

and thereby hold the door tightly closed, and this action is aided by the weight and stiffness of the curved end 15 of the connecting link, as before stated.

While I have shown and described my in- I vention in considerable detail, I do not wish to be limited to the exact construction speci-- fied, but may use such substitutions, modifi cations or alterations as fall within the scope of my invention, as set forth in the claims.

WVhat I claim as new and desire to secure by Letters Patent is '1. In a railway car, a car door operating shaft, a crank arm mounted thereon, a longi- V tudinal center sill composed of a pair of members each having a vertical web with outstanding flanges, a flanged reinforcing member secured to each of said webs near the 1 bottom edge thereof, a short rolled angle section, one leg of which abuts and is secured to the lower portion of each flanged reinforcing member aforesaid, the other legs of said angles extending below the centersill, and each provided with a cylindrical opening therein, adapted to receive the crank i arm, and thereby form a journal bearing for the car door operating shaft.

2. In a railway car, a door operating: crank-arm, a longltudmal center s1ll com-;

each member having a web with outstanding flanges, a flanged reinforcing member secured to the inner side of each web near the bot- 5 tom edge thereof and projecting inwardly toward the center of the center sill, short pieces of rolled angles abutting and attached to each of the bottom portions of said -rein' 13 forcing members, with the downwardly ex- In testimony whereof I hereto affix my tending portions of said rolled angles near signature inthe presence of two Witnesses. each other, each of said rolled angles being RALPH V.
