The main objectsofniy'invention are to reduce machining and assembling of the brake cylinderstructure and thesaddle mem- T "her" on which they are mounted}. to avoid the'necessity of frequent inspection and'tight I ening of brake cylinder mounting elements;

a systems. I r r g V r -r I attain these obje'cts by forming one or cent portion of the the saddle, boiler support, main steam cylin- 1 to simplify the to require repairs. Another-object is toform a fluid Wayintegral withthe and saddle structure. I k I I Iihave developed my invention with special attention to other forms of pneumatic or hydraulic; brake more brake cylinder elements integrally with the locomotive saddle structure which forms a transverse brace for the locomotive underframe and this structure can also carry the steam cylinders and'the smoke-boxor'adja boiler shelL, Preferably,

Steam cylinders and the rear vertical wall 2 of the saddle is a part of brake cylinder bodies 9 formed integrally therewith and projecting from the wall with their axes disposed horizontally and the wall 2 of the saddle forming the inner ends or heads of the cylinder bodies 9. The outer ends or heads 10 of the cylinder bodies are formed separately and secured to the cylinder body side walls by studs, bolts 01 weldin".

The saddle wall 2 is recessed as indicated at 11 to provide an air passage from a supply pipe 12 at the side of the cylinder body 9 to the interior of the body and the wall is similarly recessed at 13 to provide an air passage between the adjacent brake cylinder bodies 9.

A bushing 59 is preferably inserted in the cylinder so as to provide renewable means for wear on the interior of cylinder walls.

A saddle of this type may be readily cast in one piece and machined in the usual boring machines and applied to the ordinary locomotive frames without special worl: on the latter.

In the construction shown. in Figures 4, 5 locomotive framing comprises a box-shaped section having a bottom wall 14, side walls 15 and a top wall 16, and a saddle member extending transversely of the boxshaped section 14l5-l5 and above the same 7 and including a front wall 17 and a rear wall 19 and supply chambers 20 are integral with the framing and saddle structure and the latter also includes an integral boiler support 21. Projecting rearwardly from the rear wall 18 of the saddle structure are the curved walls 22 which merge with each other to form a common partition wall or web 21 and also merge with the wall 18 and cooperate to formhorizontallydisposed bral'ie cylinder bodies 23 having removable bushings 60 and removable non-pressure ends 24 provided with release spring recesses 25. A projection F, integral with the 7 bottom wall 14: of the bed, provides a fulcrum for the mounting of the bralrelever indicated at L. Obviously, the relation between the same and brake cylinder body 23 will be maintained throughout the life of the locomotive structure.

In this preferred construction, the parts specifically referred deck 95, the pilot beam 27, the valve gear support brackets 28, pedestals 29, etc. I prefer to f rm these parts by casting the same in one piece but it is practical to make some of the parts separate from each other by casting or by any combination of the methods of casting, welding, forging, etc, and then unite them by welding. In any integral structure, whether formed by casting or welding or otherwise, the elimination of attaching flanges, bolts or rivets, and the necessity of to are integral with the entire locomotive bed which includes the front providing space for getting at the attaching elements for original installation or for main tenance or repairs, and the elimination of fitting of the parts for original installation and the elimination of play between the parts, due to wear and use, are some of the marked advantages which are not present in the builtup structures previously used.

In the lnoditication illustrated in Figure 7, I show a sad lie '30 having single air brake cylinder 31 formed integrally therewith with its axis disposed vertically and with both ends of the cylinder and 33, respectively, detachably mounted on the cylinder, the side wall of the cylinder being braced, by suitable ribs-B l, at points spaced from the upright wall of the sad le. This structure illustrates saddle applicable to the frames 35 of the locomotive and also shows the steam cylinders 36 and supply chambers 3'? formed separately and applied to tae saddle in accordance with a well-known practice.

In Figures 8, 9 and 10, I show a pair of air brake cylinders 38 disposed vertically, and mounted at points spaced from the saddle wall 39 by means of brackets lO provided with recesses 4:1 for lightening the same and facilitating the casting of the cylinders integrally with thesaddle structure. The saddle is formed integrally with the longitudinal members d2 of the bed and includes integral steam cylinders 4C3, supply chambers 41 i and a boiler support d5. Exhaust passages 4t6 extend inwardly of the saddle outer walls and unite in a centrally disposed eX- haust HOZZlQ' l'I, similarly to the corresponding parts in the structure shown in Figure l. Both ends 418 of. cylinders 88 are removable, which may be desirable under some manufacturing conditions or for other reasons. 7

In. Figure 11, I illustrate a detail of a very similar construction in which the non-pres sure head 49 of the cylinder 50 is formed integrally with. the same and with the bracket 51 which unites the cylinder with the saddle 5:2, but the pressure head 53 is removably applied to the cylinder 50 in the usual manner.

In Figures 12 and 13, fication particularly adapted for a three cylinder locomotive which the space immediately under the boiler support 54 is not available for mounting the brake cylinder due to the projectio with the ..m cyli or In this structure, I provide a brake cylinder 56 beneath the steam cylinder disposed on an incline similar to cylinder 55, the inner end 57 of the brake cylinder forming an intermediatewall or rib for the saddle 58 and serving to brace the same and the lower wall of the steam cylinder 55.

In Figures 14 and 15, I illustrate another modification of the saddle structure in which I illustrate a modiparts on or associated messes the complete saddle is formed in two halves 61 and 62, each of which includes a main steam cylinder 63, a steam supply chamber :i flOQA. locomotive saddle'member having a main' steam cylinder, a steam; supply chember, and: a. brake cylinder body, all formed.v integrally; t I

The saddle members are provided with flanges 67 for attachment to each other and with suitable elements 68.for attachment tothe brace 69 of the locomotive frame. Each of the saddle pressure head of the cylinder and the side wall 71 of the cylinder is integral [with and projects from the saddle wall 70. Clearly,

this type'of saddle member could have a vertically disposed cylinder integral-therewith illustrated.

Ineach of the Figures 3,5 and 9, I illustrate the adjacent truck wheels,.brake lever, piston, release spring and connection rods, but it will do not form any part of my present invention as they have long been in common use and .1 illustrate them merely relative to the brake they'are associated.

Various other'modifications of the details of the device and relative arrangementof the parts shown may be made without-departing from the spirit of my invention and I contemplate the exclusive use of such variations as come within the scope of myclaims.
