Our invention relates to railway rolling stock and consists in a novel railway underframe structure and more particularly in the combination of a fluid reservoir and a fluid brake cylinder with the underframe.
Customarily, reservoirs and brake cylinders have been completed separately from the underframe structure of the vehicle and have been provided with flanges adapted to beattached to brackets secured to the vehlcle framing and by which the reservoirs and cylinder bodies themselves have been secured in place. Such fabricated construction requires frequent and detailed lnspect on to see that the rivets or bolts are tight to insure maintenance of proper assembly.
Attention is directed to our copending application, Serial No. 368,509, filed J une 5, 1929, in which we show brake cylinder bodre integral with a locomotive frame.
The main object of our invention s to secure a rigid and permanent relationship between the air reservoir and brake cylinder member on the one hand and the underframe structure and air reservoir and brake cylinder member on the otherhand by making the reservoir and cylinder member integral with the underframe or a part thereof.
Another object of our invention is to reduce maintenance attention and delays by making the reservoir and cylinder member integral with the underframe or a part thereof.
Other detail objects of our invention will appear from a reading of thefollowin'g description of the device with reference to the accompanying drawings of'the same. I
The reservoir and brake cylinder elements may be formed integrally with the underframe structure by casting or by any combination of the methods of casting, welding, forging, etc. i
Figure 1 is a top view of an underframe structure embodying one form of our invention showing a fluid reservoir, and empty and load brake cylinder bodies, each integral with one or more of the transoms of the underframe. l p
, Figure 2 is a side view of the structure shown in Figure 1. V

Figure6 is a top view of a modified form of our invention. I
Figure 7 is a longitudinal vertical section taken on the line 7 '7 of Figure 6.

Figure 13 is a top view of a separate needle beam showing a brake cylinder body mounted integral therewith and embodying another modification of our invention Figure ltis a side view of thestructure shown in Figure 13.
[Figure 15 is a transverse vertical sect-ion taken on the line 15-15 of Figure 1 1.
Figure 16 is aside view of a cross bearer member having a brake cylinder body integral with a part thereof and embodying another modification of our invention.
Figure 17 is a transverse vertical section taken on the line 17-17 of Figure 16.
In the structure illustrated in the first five figures, the sides of the underframe are indicated at 1, and are integrallyconnecte'd by spaced transoms2, 3, 4, 5 and 6, which are integrally connected to parallel longitudinal center sills 7 and 8.
In this form of our invention, the reservoir member 9 and load brake cylinder member 10 comprise a unit which extends between the two transomst and 5 and, is integrally connected to those transoms and thereby held in permanent rigid relation with the underframe of the vehicle. The reservoir is usually of cylindrical shape but may be made of oval or any other shape more desirable in the particular structure. Y I
The reservoir 9 and brake cylinder bodylO have acommon wall 13 forming the pressure head for the cylinder. The outer end wall of the reservoir is separate from the bod 11 is united with the transom 3. Brake cyland has a brake rigging bracket 14 integral i inder body 11 is shown with a non-pressure head 15 integral therewith.
Mounted on the end of the reservoir member 9 nearer the transom 4: are the change over valve 16 and the triple valve 17.
Connecting the brake cylinders and the'reservoir is a system of brake rigging by means of which any approved braking system may be operated by fluid pressure or hand, as is I desirable.
In'the modification illustrated in Figures 6 and 7, a portion of an under-frame structure is shown in which a fluid reservoir and brake cylinder body 31 are formed integral with each other and disposed end to end and united with the transoms 32 and 33. The outer end" wall of the reservoir merges with the web of transom 32. Running through the reservoir 30 and welded to the ends thereof is a tube 34 leading from the triple valve 35 through the opposite end 36 of the reservoir also formingthe cylinder pressure head.
In the modification illustrated in Figure 8, the reservoir member 40 has one end 41 separable. i In the modification illustrated in Figure 9, the reservoir 50 is like the one shown in Figures 6 and 7 but extends from transom 52 to transom 53 and is integral therewith, the
transom webs forming the end walls of the reservoir, In this arrangement we have shown the brake cylinder body 51'as formed separate from the reservoir although at tached thereto. Obviously, in this and in other forms of our invention, the brake cylinder could be mounted on a different part i of the underframe.
' In the modification illustrated in Figure 10, the brake cylinder'non-pressurefhead 61 only is shown integral with the transom 62, the body 60 being formed separately and attached to the transom. No reservoir elements are involved. V
a In the modification illustrated in Figure 11, a vertically disposed cylinder body 7 0 is shown integral with transom 71 and includes an integral pressure head72. I
In the modification illustrated in Figure 12, a vertically disposed cylinder body 807is shown having separate heads, the non-pres x sure head 81being integral with the transom 82. r i i 1 i In the modification illustrated in Figures 13, 14c and 15, a separate needle beam 90 is shown integrally suspending a brake cylinder body 91 and non-pressure head 92 integral therewith, a web 93 depending from the top of member 90 to the top of body 91.
i In the modification illustrated in Figures 16 and-17, a cross bearer 100 is shown having a member101 with which a brake cylinder body 102 and non-pressure head 103, are integral. V V Some features of our invention Lma'ybe included in any structure in which instead of the entire reservoir or cylinder body being integral with the underframe as described above, a part of such reservoir or cylinder member or suitable brackets for supporting the reservoir or cylinder member are integral with the underframe.
Other details in the structure of our invention may be modified without departing from the spirit thereof and we contemplate the exclusive use of allmodifications that come within the scope of our claims.
