DRAFT RIGGING.

Application filed December 30, 1921. Serial No. 525,874.

To all whom it may concern:

Be it known that I, DONALD S. BARROWS, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Draft Rigging; and I do hereby 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. e The invention relates to draft rigging for railway cars and more particularly to a combined backstop and center filler casting designed to be secured to the car center sills so as to transmit thereto and to the carare arranged to receive and distribute, with-- out distortion, the enormous shocks or blows to which the casting is subjected in actual use.

To this invention, generally considered, consists in constructing a backstop with side walls which are preferably adapted to overlie and be secured to the webs of the adjacent car sills, and in providing said walls with inwardly converging portions adjacent the forward ends thereof, said portions being united by an end wall or web forming an abutment for the movable, part of .the draft rigging, a longitudinal upright web extend ing rearwardly from said end walls and transversely extending, downwardly inclined webs uniting each side wall to said upright web, said inclined webs also being united to the said end wall. I

Another feature of my invention consists in forming a backstop with end walls, one

of which forms an abutmentfor a movable part of the draftrigging, said walls being end, the principal feature of my I integrally connected to the side walls I at points spaced from the upper and lower portions of the latter, and in providing a plurality of transversely extending webs uniting said side walls, one of said webs being adapted to connect the said end walls, the other web being vertically spaced therefrom.

Still another featureof my invention consists in providing a backstop with side and end walls integrally connected, one of said end walls forming an abutment for a movable member of the draft rigging, an upright web extending between and uniting said end walls adjacent the central portions thereof, and a transversely extending web connected to said upright web and to said side walls and spaced from the adjacent lower edges of said end walls.

There are other features of my invention relating to form and details of construction,

as will be hereinafter apparent from a more illustrated in the accompanying drawings,

wherein Figure 1 IS a shown in dotted lines,

Figure 2 is a central longitudinal vertical sectional view of the construction shown in Figure 1. Figure 3 is a transverse sectional view taken on line 33 of Figure 2,.the direction of view being indicated by the arrows adjacent the ends of said section line.

. 8 0 top plan view/of my combined backstop and center filler casting, the. abutting rear end of the draft yoke being Figure 4 s a rear elevat onal view of the casting, sections of the center or draft sills being indicated by dotted lines.

In the drawings, the numeral 1 designates the combined back' stop and center filler casting which is designed to cooperate with the draft rigging and to provide the center filler member of the ordinary type of built-up bolster. The casting 1 is adapted to fit between the webs of the center or draft sills 2 and to be rigidly attached thereto in any suitable manner. For convenience, I have illustrated my attachment in connection with the channel sills 2 having the flanges 3 thereof turned inwardly. as clearly shown in Figure 4.

is adapted to engage the inner end of a yoke 5 to limit the inward movement thereof and to act as an abutment for transmitting to the car sills, through features hereinafter apparent. the butting forces or blows transmitted to the casting by means of said yoke. [The casting 1, as here illustrated, is of substantial box shape and comprises, in addition to the front or outer wall 4, side walls 6, 6, a rear end wall 7 an intermediate wall 8. and a floor or base member 9. Adjacent their forward ends and intermediate the upper and lower edges thereof, the side walls'6, 6 are provided with inwardly converging portions 10 for connecting the side walls to the front wall 4. These portions 10, which, for convenience have been described as converging portions of the side walls, might also be described as divergent portions of the end wall 4.

The end walls 4 and 7 are preferably braced by a plurality of longitudinally extending upright ribs or flanges 11, 11 and 12, the latter being arranged on the center line of the casting. In order to reinforce and strengthen the casting against lateral strains, I provide each side wall 6 with an inwardly extending, downwardly sloping web 13 the adjacent edges of said webs being preferably integrally connected to the central upright web 12, as clearly shown in Figure 3. These webs 13 also extend from end wall to end wall and therefore materially strengthen the castingin a longitudinal di-- 9, as clearly shown in Figures 1 and 2.

The web 12 extends the full height of the end Walls 4 and 7, both above and below the transversely extendingwebs 13, and is preferably downwardly extended below the lower edges of the said end walls and integrally connected to the base or floor plate 9 of the casting. The ribs 11 preferably extend above the upper faces of the flanges or webs 13 and are connected to the intermediate wall 8. Intermediate the wall 8 and the front face 4 of the casting, and below the webs 13, I preferably provide further reinforcing ribs 15 which are arranged for convenience, in alinement with the corresponding ribs 11.

The side walls 6 are provided with a pinrality of rivet receiving openings 16 through which the rivets or other securing means, for connecting the casting to the sills, are adapted to extend, and in order to provide sufli'cientroom to permit the driving of the rivets, which are adjacent the ribs 11, I

reduce the height of these ribs at their intermediate portions so as to provide ample clearance. 1

The intermediate wall 8 is preferably provided'with inclined portions 17 which extend the full height of the side walls 6 and further reinforce the same against buckling under strains imposed upon the casting through the base or floor plate 9.

The base plate 9 is preferably provided adjacent its side edges with inclined portions 18 which overlie and conform to the adjacent flanges 3 of the center lines. The side walls are preferably extended in rear of the rear wall 7 and may be connected to this rear wall by triangular reinforcements 19. These reinforcements are, for convenience, formed in parallel planes to the webs 13.

It will be observed that the end walls 4 and 7 are spaced attheir lower edges from the base or floor plate- 9. By this construction I avoid all necessity for perforating the webs 13 since access to the rivet openings 16 may be had from both the front and rear ends of the casting. In this connection it might be pointed out that by arranging the webs 13 at an angle to the horizontal, I not only reinforce the end walls substantially along the center line thereof, but am enabled to provide an additional row of rivet open-- ings in line with the intersection of the webs 13. and 12 but spacedfrom the marginal edges of the webs 13. v

A combined backstop and center filler casting formed as here described is advanm0 tageous in that it presents to bufling shocks or blows a section of substantially I-beam form whose walls are disposed so as to resist most effectively these shocks and blows and to transmit these blows from the buifing face to the various structural membersof the casting, without distortion or deformation. By arranging the transverse webs at an angle, I provide a symmetrical casting in relation to the rivet openings and thus prevent turning moments upon the rivets, that is the rivets by which the casting is secured to the sills, are subjected to shearing strains alone. It will also be apparent that by means of the internal ribs and flanges the casting hereinbeforedescribed is so reinforced that all stresses to which it may be subjected in service, are amply resisted by sufficient sections of metal so economically arranged that the casting, While possessing'great strength, is comparatively light in weight, and is moreover a simple casting both to mold and cast. 7
