IVIESNE ASSIGNMENTS, TO GENERAL STEEL CASTINGS CITY, ILLINOIS, A CORPORATION OF DELAWARE LOCOMOTIVE srnuo'runn Application filed June 5, 1929. Serial No. 368,509.

Our invention relates to railway rolling stock and consists in a novel framing structure particularly adapted for useinrailway locomotives.

5' A locomotive usually includes a plurality .of pumps for water and air and cylinders with pistons operated by. compressed air for actuating the brakes, etc. Heretofore these pump bodies and air brake cylinders have 10 been completed separatelyfrom-the locomotive structure and have been provided with bracketsv by which they may be secured to the locomotive framing, etc. The locomotive structure has also included brackets or other provision for the mounting of the pumps and cylinders, etc., and this construction'has necessitated a great deal of machining, for the purpose of fitting theparts together, drilling, for the purpose of providing holes for securing bolts and rivets, andfrequent inspection of the assembledstructure to-insure the maintenance of the proper assembly.-

Frequently the securing elements are not readily accessible and canonly be inspected 25 and tightened with difficulty.

It is the main object of our invention to eliminate the above mentioned disadvantages of the usual structure by forming brake cylinders and the bodies of air compressors, and

ing of the locomotive whereby a fixed relation between theparts will-be maintained and inspection of the same and tightening of securing elements can beavoided.

We also desire to utilize the brake cylinders for bracing the framing structures and thereby eliminate the use of many bracing mem bers previously required which served no other purpose. I

Another object of our invention is to form the inner heads of the pump' cylinders'and either the pressure head or non-pressure head and spring housing of brake cylinders integral with the cylinder bodies and the framing of the locomotive.

Another object of our inventon is to water pumps, etc. integrally with the framcanbe formed integrally with the framin of the locomotive by casting or by any combination of the methods of casting, welding, forging, machining, etc.

the cylinders 14 to 21 may In the the side frames of the bed are indicated at 1, each having integral pedestal-forming portions 2 and united with the corresponding side frame on the opposite side of the locomotive by horizontal webs 3 and 4 provided with suitable openings 5 to lighten the structure and also to provide access to the interior 'of The steam cylinders 6, steam supply chambers 7, boiler saddle 8, front deck 9, buffer 10, valve gear brackets 11, brake hanger lugs 12, and equalizer fulcrums 13 and various other parts are also formed integrally with the framing and greatly reduce the amount ofmaohining and assemblingilabor and the number of elements otherwise required for securing the various parts to the framing. Formed integrally with the side frames in front of the cylinder and boiler saddle on the-near side of the locomotive are cylindrical chambers 14, 15, 16 andw1-7, the same comprising, respectively, high pressure-air, low pressure steam, Flow and the cylinder and pump parts.

lindrical bodies 18, 19, .20 and 21 forming the water and-steam cylinders of a two cylinder feedrwater :pump, the lower cylinders being the water-cylinders and the upper cylinders being .thesteam cylinders.

Each of the elements 14 to 21, inclusive, has its'inner head formed integrally with itsbody and is provided with a detachable outer head which'may be secured to .the body in the usual manner. All of the elements 14 .to 21 are-integral with the front portion of the bed and with each other and are provided with suitablebraces, such as indicated at 22, also formed integrally with the framing'and thepumpbodies'. All-of these pump parts'have theiraxes disposed vertically and may be machined on a suitable machine 'with the assurance that when they are once C0111- pleted their alignment and other relations with each other will be maintained throughout the life of the locomotive. If desired, be provided with renewable bushings of'brass, Monel or other metal-as is icommonipractice in cylinder construction. 1

Preferably, each of the steam chambers 15 and 19has anintegralexhaust steam passageway '23 vand 24,- respectively, connecting it to the adjacent exhaust steam passage25 leading. fromthe adjacent mainsteam supply chamber will be mounted over the opening 26 in :the boiler saddle.

' Similarly, the steam passages 27 between 7 to the exhaust stack which 2 suitable coring, during the casting operation. These passageways carry the steam to or from the cylinders according to the direction of movement of the pistons.

The cylinders 14 to 17 comprising the air pump structure are arranged in sequence so that the steam used in the high pressure cylinder 17 is discharged into the low pressure cylinder chamber or body 15 and the air compressed in the low pressure cylinder 16 is discharged through passageway 29 into the high pressure cylinder 14.

' Detachable outer heads 30 and 31 are provided forvthe cylinders and the upper head 30 will include suitable valve structure for 'controllingthe steam admitted through pipe 321to passage33 formed-integrally with the cylinder wall. Lower head31w1ll include an air inlet 34, valve chamber, valves, vand a passageway leading from cylinder 16 to the other pump and each receiving water':

Passageways 42a connect each water cylinder with each valve chamber 42;. .A' suction .air chamber 38 integral with and betweenuthe upper steam cylinders :19 "and K21vand the ilower water cylinders 18 and. 20=is eonnected with supply valve passageway 45 'by'm'eansxof passageway 44 andserves'to equalize "the pressure and prevent-pounding in the waterinlet pipe 37. A separately formed :head' 40 is applied to the steamcyIind'ers-19 andi21andincludes suit- :of cylinders418=and :20. The pump strucitureper 'se forms-no apart of our present invention and is "welL-known-in vthe art as the lesco pumps Exhaust steam passageways 24a are integral with cylinders t19and121 and connect with the passageway '24. l

Ashield 48is' locatedlin front of each pump structureaand preferably is formedintegrally with the'deek plate 9and bufl'er beam 10 and has a general U-shaped section horizontally disposed "whereby Zits: rigidity is maintained and, on the feed water pump 'side, the, outer water valves are substantially enclosed by the corresponding shield. i

At the rear of'theboiler saddle and main steam cylinder structure, I provide a series of brake operating cylinders 50, 51, 52 and53, each of the cylinders 51 and 52'being located intermediate the side frames 1 with its axis disposed vertically. The side walls of these vertically disposed cylinders merge with the horizontal webs 3 and 4, cooperating with the latter to form a ri id brace between the -"spaced side members; referably, one of the ends of each cylinder is-formed integrally with the remainder of the cylinder and bed structure. Cylinder 51 has its lower or nonpressure head 51a formed integrallyand includinga housing 54- for the release spring 55, (Fig. 14). r

Horizontally disposed cylinder 53 (Fig. 2') is shown Without either end or head being formed integrally therewith, the heads being applied in the usual manner; This arrangement may be embodied in any of the cylinders. Cylinder 52 (Fig. 15) is shown with its pressure head or upper head 56 formed integrally and the lower or non-pressure head 57 being applied in the usual manner. v p p The pedestal-forming portions 2 on opposite sides of the bed are connected by suitable braces 58and these braces extend a substantial distance below and to the side of the adjacent air brake cylinders and are spaced from web 4 so as to facilitate the molding of the cylinders and avoid interference withthe operation of thepistons in the cylinders and with the levers connected to the pistons Cylinders 50 (Fig. 2) are disposed with their axes horizontal and are'arranged side by side and partially located ina depression formed in the top member 3 of the bed (Fig. 10). The rear heads or ends ofcylinders 50 are in line with and form part of a continuous transverse vertical wall 59 extending from side to side of the bed and the outer ends of which form brackets 60 on which the valve gear mechanism (not shown) may be mounted. Obviously, this cylinder structure braces the adjacent parts of the bed and, obviously, the integral formation ofthe,

cylinder side framing eliminatesthe necessityof machining numerous surfaces on separately formed cylinders and the machining of suitable supporting brackets on the frame and the provision of amultitude'of attaching bolts or rivets. Moreover,"the cylinders will always be rigid and will not require any inspection or tightening of elements in order to maintain their assembly with thebed structure. a I I Each of the brake cylinders 50 forms part of an individual brake mechanism for a front driving wheel on a corresponding side ofithe locomotive as shown by the brakelever pull rod'66, and brake'head'67r Likewise,

each of-the brake cylinders 53 forms part of an individual brake mechanism for a rear driving wheel on a corresponding side as shown by the brake lever 68, pull rod 69, and brake head 70. The brake cylinders 51 and 52 form parts of an individual brake mechanism for each pair ofintermediate driving wheels as shown by brake lever 71, pull rod 72 and brake head 73. The brake leWf-s 65, 68 and -71 are fulcrumed in brackets 74 which are cast integral with the locomotive bed.

It is to be understood that our invention is. not to be limited to this arrangement of brake cylinder and brake mechanism, but includes arrangements where either one or more of the above brake cylinders are omitted and where one or more pairs of wheels are controlled by the same brake mechanism, or where all of the driving wheels or all of the driving wheels on each side are controlled by the same brake mechanism, or where each driving wheel is controlled by an individual brake mechanism.

In Figures 19 to 21 we illustrate a modification in which the two forward cylinders 61 are disposed vertically with their side walls. 62 merging with the inner vertical walls 63 of the bed side frame. In this construction, the cylinder will not be directly connected with the valve gear bracket 64 but, nevertheless, will serve to brace the bed structure adjacent and in addition to the valve gear bracket." 1

While we prefer to form the entire structure describedin a single casting, we consider the welding together of two or more units to complete the structure as being within the spirit of our invention. Nor is it necessary .to form the entire bed in an integral structure. A separate cradle structure or a separate front end member could include the integral brake cylinder structure which is the gist of our invention. In any form, the objects stated in the forepart of this specification are attained with a marked degree of success.

Many other details of our construction may be modified without departing from the spirit of our invention and we contemplate the exclusive use of such variations as come within the scope of our claims.
