To all jw/wm, it may concern.'

Be it known that I, DONALD S. BARnows,

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 Car 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 car underframes for railway cars and more particularly to a strong, reliable and efiicient met-allie structure adapted to be applied generally to wooden underframe cars to reinforce the underframes thereof so as to adapt said cars for use under modern service conditions.

To this end the principal object of my invention, generally stated, is to provide a metallic structure adapted to be used with the underframe of wooden cars, said structure being used to reinforce the car sills so that bufling and pulling shockswhich exceed the capacity of the draft rigging are transmitted to the underframe at a plurality of spaced points in the most advantageous manner.

Another object of my invention, generally 39- stated, resides in the combination of a car underframe and spacedV metallic center sill reinforcing members adapted to be connected to the center sills of the car, spaced draft sills arranged beneath the center sills, a backstop member ends of the draft sills, said backstop member being spaced from the bolster of the car and adapted to bridge the inner ends of the draft sills,r and means involving a gusset plate for firmly uniting the center sill reinforcing members with the draft sills.

Another object of my invention is to provide,- a car uuderfranie including in combination center sill reinforcing means connected to the center sills of a railway car, draft sills arranged beneath the center sills. said draft sills terminating short of the bolster and having formed at their .inner ends a backstop member, and an interposed connect-ing means riveted to the center sill reinforcing means and draft sills, said connecting means being adapted to .firmly imite the center sill reinforcing means and draft sills with the bolster at a plurality ofvpoints.

.Si further object of the invention is to connected to the inner Serial No. 569,706.

provide a metallic structure which can be easily applied to underframes of cars at a comparatively small cost with minimum eX- penditure of labor, thereby permitting employment of modern types of draft rigging in combination with under-frames of cars requiring modifications or changes to bring them within the present M. C. B. standards..

A still further object of my invention, generally considered, is to provide means in connection with a draft rigging having a. slidable connection between the coupler and yoke member, said means including wrought members connected to the car sills and positioned in rear of said yoke member to hold the same from rearward movement to transmit bufiing shocks to said sills.

There are other features of the invention as will be pointed out hereinafter in connection with the detailed description of the embodiments of my invention illustrated in the accompanying drawings in which* Figure l is a plan view of my improved metallic construction, a portion thereof being broken away to more clearly illustrate the associated parts, and a portion of thc rear end of the movable element of the draft rigging being shown.

Figure 2 is a vertical longitudinal. sectional view on the line 2 2 of Figure l:

Figure 3 is a horizontal sectional view on the line 3-3 of Figure 2.

Figure 4lis a vertical transverse sectional view on the line li--i of Figure 2.

Figure 5 is a detail view of the rear end of the draft sills illustrating a modiiied forni of channel loop construction connecting thc inner ends Vof the draft sills and associated backstop.

Figure G is a vertical transverse sectional view on the line t-G of Figure 5.

Figure 7 is a view part-ly in plan and partly in section illustrating still another form of my invention wherein an vintegral end or yoke portion connectsthe inner ends of the draft sills.

Figure 8 is a vertical longitudinal sectional view through the form of car underframe and backstop member. shown in Figure 7.

Figure 9 is a detail vertical transverse sectional iiew on the line 9 9 of Figure 8.

In the drawings I have illustrated only a portion of the car underfraine adjacent the body bolster. It is to be understood, howsimilar parts in the several views. the center sills of the car are provided with center sill reinforcing means, said reinforcing means including spaced angle members er sills 1-1 adapted to be connected to the said center sills of the car underfranie. The bolster may be of the usual construction, the

i arm portions 2 2 thereof extending transversely of the car upon either side of the center sills, and being interconnected with the bolster center filler 3, the latter being provided with the center thimble el.

The draft sills 5-5 are connected to the bottom flanges of the center sill reinforcing means by means of rivets 7. A tie member or cover plate 8 of channel construction bridges and unites the upper web portions of the center sill reinforcing members, thereby further bracing said reinforcing members. llhe inner ends of the draft sills terminate short of the bolster and provided at said inner ends is a backstop member 9, said backstopl member being preferably spaced from the bolster and adapted to receive bufling shocks from a novable element of the draft rigging, shown herein as the yoke 10, of the well known Farlow equipment.

The backstop member 9 is formed of an end wall portion 11 arranged in the 1rape of a loop or strap which, together' with the forwardly extending portions 12 thereof, produces a horizontal U-shaped yoke inember bridging and connecting the inner ends of the draft sills. Each forwardly projecting portion 12 is connected at a plurality of points by means of rivets 13 to the respective web portions of each draft sill, said rivets being arranged so as to provide a strong and rigid connection between draft sills and the curved end wall of the backstop member. The backstop casting` 14 is connected to the curved end wall portion 1l by means of rivets 15, said casting being suitably reinforced by a plurality of webs or flanges 16 joining opposite end walls of the castinge rlhe rear wall of the backstop casting 14 is curved and is designed to tit the interior face of the end wall portion of the U-shaped member. The front wall of said backstop casting is formed with a buling face adapted to receive the bufling shocks incident to service through the yoke member 10. The front wall is designed to rearwardly merge into the curved or rear wall of the casting in the angular manner as shown in Figure 1.

The top flange of each draft sill is extended rearwardly beyond the buffing face of the backstop member7 as shown at 17, the rivets 7 uniting the center sill reinforcing members or bars, and draft sills preferably extending the length of said top flanges, thereby providing a strong and durable connection capable of transmitting bufling shocks to the forward portions of the center sills and throughout the length of the reinforcing meansy connected to said center sills.

The means interposed between and connecting center sillreinforcingmembers,draft sills and bolster, include a gusset plate 18 connected to the projecting arms 2 of he bolster by means of rivets 19. Opposite forwardly projecting portions 2O are provided adjacent a central cut-away portion of the gusset plate, said projecting portions ei:- tending forwardly of the backstop member and being connected by means of a relatively large number of the connecting rivets "I to the bottom Vflanges of the center sill reinforcing members and the upper flanges of the draft sills, including the rearwardly extending upper portion 17 of said upper draft sill flanges. The gusset plate covers a relatively large area, the rearwardly extending portions of the upper flanges of the draft sills providing an additional riveting area. in the rear of the backstop and serving to interconnect the center sill rein forcing means` the associated draft sills and backstop, so that butfing strains will be transmitted from the draft sills to the forward ends of the center sills as well as through the gusset plate to the bolster.

Filler strips 21 may be interposed between the upper flanges of the draft sills and the bottom flanges of the reinforcing` members, said strips being provided forwardly of the gusset plate projecting portions 20, as shown. Other filler strips or shims 22 may be interposed. between the gusset plate and the top flanges of the draft sills, and it'will be understood that the proper level of the parts can be determined by the interpositioning of said filler strips.

In the construction shown in Figures 5 and 6, the strap or loop member 23 connecting the inner ends of the draft sills is of channel shape, the forwardly projecting portions 24- of which are firmly connected to the inner ends of the draft sills by means of rivets 25. A backstop casting 26 is connected to the vertical wall or web portion of the channel upon the interior fac-e thereof` said casting having a curved rear wall contacting the interior curved face ofthe channel bar and being provided with a front wall forming the buflng face against which the yoke member of the draft rigging abuts feasting 26 to the looped -channel bar.

`upon butling movement. Reinforcing and bracing Webs/27 are formed on the balckstop member, as shown. Rivets 28 connect said It will -be apparent that the arrangement of the looped -ch-annel bars uniting the innei` -ends `of `the channel draft sills provides a 'inga curved rear Wall to which is connected thebaclrstop casting 31. The baclsto a casting is `provided with a front wa-lland bu ng face cooperatively vassociated with the movable yoke member. A'curved rear Wall is formed on the backstop casting, rivets 32 passing through 'saidvvall and 'serving to firmly connect `the casting to the linterior face ofthe curved rear Wall of the iU-shaped or yoke member 29. Vertical and horizontal bracing Webs or 'flanges 38 lare formed on lthe backstop casting "for `reinforcing the vbuffing Wall, as will be understood.

The means connecting the upper flanges of the contiguously formed draft sills to the center sill reinforcing 'members includes a gusset plate 34 interposed between the reinforcing sills and the upper flanges or the draft sills, said gusset plate bridging 4the, respective sills and having portions thereof connected to the bolster of the car underframe, as clearly shown inl Figure '7. The gusset plate is provided with projecting portions 35, said portions extending forwardly ofthe draft sills and backstop member. Rivets 36 firmly imite the several parts together, lsaid rivets passing through the gusset `plate and adjacent upper flanges of the draft sills and bottom flanges of the center sill reinforcing members. In this form of the invention it Will be seen `that the rivet connecting means extends continuously around the rear end portion of the draft sills, thereby providing an increased and particularly effective riveting area for uniting the several parts, which, vtogether with the integral form of vbent draft sills, provides a comparatively simple, strong and durable construction in `which huifing shocks can be taken through the backstop member and transmitted to the forward portions of the center sills aswell as to the bolster and connecting` gusset plate.

An "underframing for railway cars constructed in accordance with my present iiivention, as referred to in the several ein- Vbodiments above described, permits the buffing loads .being effectively transmitted to the car center sills at points Where the latter are best able to withstand the excessive strains. In addition, it Will be obvious that an underframe is conveniently and inexpensively `provided for older types of cais wherein modern draft rigging equipment can be easily installed.
