To all whom'-may concern:

Be it known that l, DONALD S. Bannows,

a citizen of the United States, residing at Rochester, in the county of 4Monroe and State of New York, have invented certain new and useful improvements in Car Underframes; and l 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 efficient metallic structure adapted to be applied generally to wooden underframe cars to reinforce the underframe thereof so as to adapt said cars for use under modern service conditions.

'lo this end one of the principal features of the 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 and designed to receive the butling and pulling shocks which are transmitted thereto by the draft rigging.

Particularly stated, the invention consists in providing a car underframe including in combination a backstop member associated with a movable element of the draft` rig ing and connected to a plurality of mem ers forming the draft sills, the bolster to which said draft sills are connected, and diaphragm means suitably connected by gusset plates to the bolster in the rear thereof for reinforcing the strength value of the severall parts comprising the car underframing.

Another object of the invention is to provide a car underfrarne and reinforcing' means therefor involving diaphragm members of simple construction at the rear of the bolster, said members being increased from a relatively shallow depth or cross sectional area from a point adjacent the reinforcing center sill members to a relatively large cross sectional area or depth substantially equal to the height of the bolster and immediately adjacent the rear thereof.

A' further object of the present invention is to provide a car 'underframe including a plurality of gusset plates, some of said plates being arranged to effectively connect the draft members to the bolster forwardly thereof, said gusset plates being arranged adjacent ithe backstop casting, and other of said gusset plates serving to unite the reinforcing diaphragm means and bolster at the rear thereof, the uppermost of said last named gusset plates bridging and connecting the diaphragm means and overlying the bolster.

A still further object of the invention resides in the combination with center sill remforcing members, a top gusset plate bridging and connecting ,said members at the rear of the bolster, diaphra reinforcing means formed with an o set portion adapted to receive andfit said gusset plate and having a shoulder portion at the rear thereof connected to the center sill reinforcmg members, and bottom gusset plates underlying said dia hragm means and shoulder portion, said ttom gusset plates being connected to the bolster, diaphragm means and center sill reinforcing members.

'lhere are other features of the invention as will be pointed out hereinafter in connecnection with the detailed description of my invention illustrated in the accompanying drawings in which Flgure l is a plan view of my improved construction.

Figure 2 is a central vertical longitudinal sectional view through the construction shown in Figure l. v

Figure 3 is a horizontal sectional view with parts shown in section and broken way, and other parts illustrated in elevaion.

Figure el is a transverse vertical sectional view on the line M of Figure 3.

Figure 5 is a transverse vertical sectional view on the line 5-5 of Fi re 3.

ln the drawings ll have illustrated only a portion of the car underframe adjacent the body portion. lt is to be understood, however, that the structure is duplicated at the opposite end of the car and that the center sills hereinafter referred to are preferably continuous, the said sills being adapted to extend from end to end of the car. rlfhe car underframe preferably includes the usual end sill and associated parts, not shown, but as is well understood by those skilled in the art.

Referring to the drawings in which corresponding reference characters designate similar parts in the several views, the center sills of the car are provided with center sill reinforcing means, said reinforcing means titi lilla sills of the car underframe.

plate 4, shown in the form of a stiffening channel, the flanges thereof'being connected to the inner opposed faces of the reinforcing sills 1 by means of rivets 5. Filler strips or inserts may be utilized, if found necessary, to accommodate the parts to A. R. A. standard measurements, as will be understood.

The draft members or sills are each preferably formed of angle members 6 and 7, the respective vertical flanges thereof being overlapped and united by means of a plurality of'rivets 8 extending throughout the length of said members. The horizontal flange 9 of the upper angle member 6 is relatively wide and is preferably connected, by means of a double row of rivets 10, to the horizontal flange of the angle or center sill reinforcing member, the respective vertical flanges of said angle member 6 being spaced further apart than the vertical fla es of the reinforcing sills to provide for t e use of modern draft rigging and its associated parts. The horizontal flange 11 of the lower angle member 7 extends outwardly ofthe draft sills and has connected thereto, by

means of rivets 12, the forwardly extending portion of the bottom gusset plate 13, the rear portion of said gusset plate being connected by means of rivets 14 to the bottom flange of the bolster. The horizontal flanges 11 of the angle members 7 are preferably tied together by means of the cro bar eX- tending transversely of the draft sills intermediate the ends of the backstop member,

- said cross bar being connected to the horizontal flanges 11 by some of the rivets 12, as shown.

The inner ends ofthe built-up draft sills are connected by means of angle members 15 to the bolster, the ends of said draft sills preferably terminating short of the vertical web portion of the bolster, as shown. Rivets 16 unite one arm of the angle member to the'adjacent draft sill, the other arm of said angle member being connected to the bolster web by means of rivets 17. The connecting angle members are preferably arranged upon the outside of the draft sills, as shown.

Interposed between and connecting the inner ends of the draft sills is a backstop member 18, said member being preferably spaced from the bolster and adapted to receive buffing shocks from a movable element of the draft rigging. shown herein as the yoke 1 9 of the well known-Farlow equipment. A follower member of the draft rigin is indicated by the numeral 20. The

ac stop casting or member 18 is 'formed with a front wall portion 21 having a buffing face adapted to receive the bufling shocks through the stood. Side walls 22 of the backstop casting are formed integral with the front wall and are designed to be connected to the inner opposed faces of the draft sills and more particularly the overlapped vertical flanges of the respective angle members 6 and 7. Certain of the rivets 8 serve to connect the backstop to the draft sills. The rear wall 23 of the casting is united to the front wall by means of vertically and horizontally arranged webs or flanges 24. The horizontal flange or web also unites the side walls of the ackstop. The rivets connecting the 'side walls of the backstop castin to the draft sills extend-througl1o'ut the le side walls and serve to firmly unite the backstop member to the'associated angles 6 and 7, certain of said rivets passing through both vertical flanges of the angle members' and other of said rivets passing through but the vertical flange of the upper angle member 6.

' The means reinforcing and bracing the forward portion of the underframe above described, includes spaced vertical diayoke member, as will be underngth of said l phragm members 25, each associated with an adjacent center sill reinforcing member and longitudinally disposed with relation there to. Each diaphragm member is preferably formed of a Z-bar having at its forward end an outwardly rejecting flange 26 adapted to be connected) to the rear face of the web of the bolster by means of the rivets 17 hereinbefore referred to as connecting one arm of the angle member 15 to said web. The

vertical web portion of each diaphragm member increases in depth from 'a point at the rear of the bolster .adjacent the center sill reinforcing members tothe rear edges of the bolster flanges, said web portionl extending between the flanges and terminating in the outwardly extendingflange 26, as shown. Each diaphragm member is rovided with an upper flan e 27 connected to the horizontal flange of t e center sill reinv forcing members by means of rivets 28, said flange being arranged to extend inwardly and having its forward o rtion offset to underlie the top flange o the bolster, as

. clearly shown in Figure 2. The rear end of the flange 27 is relatively thickened to form a shoulder recessed portion 29 adapted toref ceive the top gusset plate 30.

The top gusset plate 30 is interposed between the lower flanges of the center sillreinforcing members and the flanges 27 of the ing said members and extending outward diaphragm member, said gusset plate bridgy lll Aso

= ed to extend annee therefrom suitable distanc u on each side of the center sills, as shown. e forward portion of the gusset late 30 is adapted to overlie the bolster an is connected to the top flange thereof by means of a plurality of rivets 31 arranged upon the respective sides of the webportion of said bolster. The rear portion of the gusset plate terminates adjacent the shoulder portion 29. lt will be obvious that the interpositioning of the single usset plate 30 between the upper anges of t e diaphra members and the center sill reinforcing sills serves to provide a connection of relatively light weight and maximum strength value.

'llhe dia liragm members are each rovided wit lower outwardly exten ing flanges 32, said dangesbeing connected to the `respective gusset plates 33 by means of rivets 3d. 'lhe flanges 32 conform to the incline or taper of the web portion of the diaphragm members and extend throughout the bottom ed e thereof. Each gusset plate 33 is provide with an inwardly extending portion 35, said inwardly extending portion extending throuhout the length thereof. The forward en of each gusset plate 33 is connected by means of rivets 36 to the lower flange of the bolster, said gusset plate being interposed between the bottom Harige 32 an the uppermost face of the lower bolster flange 3. The rear portion of each gusset plate 33 underlies the shoulder portion 29 of the upper diaphragm dan e 27 and is adapteyond sai shoulder portion and be connected to the underface of the center sill reinforcing members by means of rivets d?.

The diaphragm members are preferably positioned out of lon itudinal alinement with respect to the dra sills, the inwardly extending danges 27 of the diaphragm members bein preferably in longitudinal alinement wit the outwardly projecting horizontal anges of the members 6 and 'l' forming the draft sills.

An underframe for railway cars constructed in accordance with my 'present invention provides a relatively light weight structure intimately associated with the bolster and capable of being readily and inexpensively assembled. llt will also be obvious that the backstop member is edectively reinforced so as to receive the bung loads, the reinforcing means being ada ted to transmit to the car sills the bun 'oads at points where the latter are best ab e to withstand the excessive strains.

ln addition it will be seen that an underframe is conveniently provided for older types of cars wherein modern draft rigging equipment can be easily installed.
