Application filed August 2, 1922, Serial No. 579,223.

To all whom t may concern.'

Be it known that l, DONALD S. BAuuows,

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 Gar Underframes; 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.

My invention relates to improvements in underframes for railwayy cars and, more particularly, to a strong, reliable and efficient metallic structure adapted to be ap plied generally to wooden underframe cars to reinforce the underframes thereof, thereby adapting said cars for use under modern service conditions.

To this end, one of the principal features of the invention, generally stated, is to provide a metallic struct-ure, said structure being used to reinforce the car sills and designed to receive the bufhng and pulling shocks which are transmitted thereto by the draft rigging.

The invention, broadly stated, consists in providing a car underframe or draft arm in which the center sill reinforcing members overlie the bolster and are connected thereto by means of an interposed gusset plate extending forwardly and rearwardly of the bolster, said gusset plate being connected to the inner ends' of the draft sills.

j. Another object of the invention resides in the provision of a car underframe including in combination longitudinally arranged car sill reinforcing members adapted tof overlie the bolster and having connected thereto depending draft members, a gussetr plate bridging and connecting the reinforcing members and overlying the bolster, and means including a plurality of abutment members or blocks advantageously located adjacent the front and rear portions of the bolster, said abutmenty members being adapted to eectively assist in resisting the strains to which the interconnected parts are subjected in service.

Another object of the invention is to provide a comparatively simple" metallic structure for car underframes involving `a single gusset plate bridging' the center sill reinforcing members Vand connecting the 'same tolthebvolster andto each. other, said center draft sill.

A further object of the invention is to provide a draft arm including in combination center sill reinforcing members adapted to be connected by a relatively long gusset plate overlying the bolster and extending forwardly and rearwardly thereof, said reinforcing members being further connected by cross braces or tie members upon opposite sides of the bolster andlnear the ends of said gusset plate.

There are other features of the invention as will be pointed out hereinafter in connection with the detailed description of my invention illustrated in the accompanying drawings inwhich- Figure 1 is a plan view of my improved metallic draft arm.

Figure 2 is a vertical cent-ral longitudinal sectional view through the construction shown in Figure l.

Figure 3 is a vertical transverse sectional view on the line 3-3 of Figure 2 viewed in the direction of the arrows.

Referring to the drawings in which similar reference characters designate corresponding parts in the several views, the wooden center sills of railway cars are adapted to be reinforced by means of longitudinally arranged angle members l-1 adapted to overlie the bolster 2. The bolster is formed with upper flanges 3 and lower flanges 4, said flanges being connected by means of the web portion of the bolster, as shown. Braces or tie members 5 connect the reinforcing members, rivets 6 uniting the bent or flanged ends of said braces to the vertical flanges or center sill reinforcing members. interposed between the upper flange of the bolster and the center sill reinforcing members is a gusset plate 7, said plate being preferably connected to the center sill reinforcing members by means of a plurality of rivets 8 and to the upper flanges of the bolster by a plurality of bolts 9.

Arranged adjacent the forward edge of the upper flange of the bolster and centrally thereo'fis an abutment member or vblock 10, said block being connected to theunder`` side ofthe gussetplate by means of rivetsv 11. The ends of the block` preferably eX- tend beyond the vertical flanges of the center sill reinforcing members and are preferably located between the draft sills, as shown. Abutment members or blocks 12 are arranged immediately adjacent and contacting the rear edge of the upper flange of the bolster, each of said blocks 12 being connected to the horizontal flange of the center sill reinforcing members and interposed gusset plate by means of rivets 13.

rlhe abutment blocks 1() and 12 are advantageously positioned to resistthe butling and pulling shocks imparted to the underframe, and more particularly the center sill reinforcing members, the forward abutment block-10 havingits end portions overlying the rear abutment blocks, as best shown in Figure 1. r

r-lhe dra-ftsills lil are preferably of channel shape, the inner ends of said sills, and more particularly the inner upper flanges thereof being connected to a horizontal flange of the center sill reinforcing members and the interposed gusset plate 7 by some of the rivets 8 hereinbefore referred to. lnterposed between the horizontal flange of each center sill reinforcing member and the upper flange of the adjacent draft sill is a filler plate lor strip 15, said filler strip being preferably positioned in longitudinal alinement with and forwardly adjacent the gusset plate 7. A plurality of rivets 1G preferably disposed in longitudinal a-linement with the rivets 8 serve to unite the filler member with the center sill reinforcing member and the adjacent draft sill. A bottom tie plate 1T connects the lower horizontal flanges of the draft sills, said tie plate being secured to the draft sill flanges by means of rivets 18. The tie plate 17 is preferably located beneath the forward end of the gusset plate and spaced from the inner ends ofthe draft sills.

,Cheek plates 1 9 are riveted to theY feces of the dra-ft sills, said cheek plates being provided with slots 2O adapted to register with slots in the draft sills for receiving a key ofA the well .known Farlow draft rigging equipment, said hey and rear block or follower being shown in dotted lines in Figure 2.

lliliiile l have for convenience illustrated the invention as applied to the three-key type of draft rigging, it will of course be apparent to those skilled in the art that the draft arm construction shown may be advantageously utilized with the more modern type of draft rigging illustrated, for

example, in the Symington Patent No.v

1,097,738, issued May 26, 1914.

A draft arm constructed in accordance With-my present invention permits the buffing-and pulling loads to be. eifeetively `transmitted to the car center sills andthe bolster,

the arrangement of abutment blocks and interposed gusset plate providing a simple, strong and easily assembled connection. l have described my invention in detail so that its nature and the manner of using it may be fully understood by those skilled in the art. However, the specific terms herein are used-in-their descriptive sense rather than in their limiting sense, and the` scole of the invention is defined in the claims.
