PATENT JOHN E. MUHLFELD, OF SCARSDALE, NEW YORK.

LOCOMDTIVE FRAME.

' Application filed June 30,

rigidly secured to the rear frames of the locomotive and of such construction that the engine cylinders may be separately or independently secured upon and removed from the opposite sides of'said front frame.

It isthe primary object and purposeof my present improvement to provide such a front, frame for locomotives as above characterized whereby, in the event 'of failure of either of the engine cylinders, it can be easily and quickly detached and removed from said frame without disturbing the connected relationship of the other cylinder with the frame or the connections between said frame and locomotive rear frames and the locomotive smokebox.

in one embodiment ofmy invention I pro; vide the front frame at its upper end with an integral smokebox saddle structurally independently of the cylinders so that when either of said cylinders is removed from its connection with the frame, the fastening bolts fixing the saddle to the boiler or smokebox wall need not be disturbed. In addition, I provide my new front frame with a forwardly extending integral bumper supporting beam, and a guide for the center pin of the frame of the forward or pony truck of the locomotive. 7

It is another detail object of'the invention to provide simple and effective means for relieving the .bolts'securing the cylinders to v opposite sides of the front frame of shearing strains and to provide means for properly aligning the cylinders with the front frame.

With the above and other objects in view, the invention consists in the improved locomotive frame and in the form, proportion and relative arrangements of its several structural features as will be hereinafter more fully described, illustrated in'the accompanying drawings and subsequently incorporated in the subjoined claims.

In the drawingswhere n I have illustrated one preferable practical embodiment of the invention and in which similar refer-' ence characters designate corresponding parts throughout the several views:

Figure 1 is a SlClB'GlQVdUOll of my 1m- 1924. Serial No. 723,098.

proved locomotive front frame, showing the same attached to the forward ends of the rear frame;

Figure 2 is a plan view;

Figure 3 is a fragmentary side elevation of the frame the cylinder being removed; and

Figure 4C is a transverse section taken on the line l% of Figure 1.

In the ordinary locomotive front frame as heretofore used in the art to which the cylinders are bolted and supported, each of the cylinders is formed with one-half of a saddle plate which are bolted together and also bolted to the underside of the boiler wall. Such old and well known construction is illustrated for instance in the U. S.

patents to Vauclain, No. 1,076,336 of October 21, 1913, and to Scoville, No. 1,172,841, of February 22nd, 1916. It is'obvious that in the event of failure of either cylinder or the steam chest associated therewith, it becomes necessary'to remove a large number of bolts connecting the half saddle plates with each other and withthe boiler or smokebox as well as the bolts securing the cylinder to the front frame and the bolt connections be tween the front and side frames or other structural parts of the locomotive before the failed'cylinder can be removed and a new cylinder applied and secured in position upon the front frame.

It is the purpose of my present invention to provide means whereby the necessity of removing alarge number of bolts will be obviatedand which will enable either cylinder to be expeditiously removed by simply removing. only the securing bolts whereby said cylinder is fixed to the front frame and without disturbing the bolting between the boiler, or smokebox wall and the supporting saddle therefor or between any other parts.

To the above end, as illustrated in't-he accompanying drawings, in one embodiment of the invention 1 provide the locomotive front framein theform of a casting includin an intermediatebod )ortion ,5 which I a is ofgeneral rectangular form having side walls 6 and end walls 7 connected and reinforced by anumber-of horizontal webs 8. It will be understood, however that the specific structural features of this body portion of the frame are not essential and might be variously modified as requiredin order pressure or single expansion cylinder might to permit of the adaptation and use of my invention in connection with different types of locomotives. However, in every case, the front frame section to which the cylinders are bolted includes forwardly and rearwardly disposed extensions and abumper beam 9 extending forwardly from the body 5 of the frame, said beam being provided with a vertical guide opening indicated at 10 for the center pin of the pony truck frame and members 11 extending rearwardly from the frame body 5 which may be connected at their ends and at the upper edges thereof by a transverse web 12. In one embodimentof my invention these members 11 are adapted frame casting are rigidly secured to the longitudinal side frames by a large number of bolts 15. Preferably, the frame members are provided with lugs indicated at 16, seating in recesses 17 in the frame whereby the bolts 15 are rel eved of shearing St-I'iLlIlS.

Other arrangements of the connection between the front and rear frames may be provided.

'Upon the opposite sides of the body portion5 of the frame, the engine cylinders aremounted. As herein shown preferably, each cylinder 18 and its steam chest 19is in the form of a one-piece integral casting 1provided. on its inner side with attac flanges 20, said flanges being preferably recessed as at 21 to receive the lugs 22 on the side walls of. the frame body. These lugs afford a convenient means for accurately positioningv the cylinder castings upon the sides of the supporting frame and in position whereby the securing bolts indicated at 23, may be inserted throughthe coinciding openings in the flanges 20 and the walls of the frame body 5. Thus it will be understood that the individual cylinders with the associated steam chest and pipe connections are independently secured and supported by the bolts 23 on'opposite sides ofthe' front frames.-

In the present instance, I have shown a hi h pressure cylinder on the right hand side of {the front frame and a low pressure cylinder on the left hand side thereof. It will be understood, however, that a high be substituted for the low pressure cylinder, oran other 'well' known type of locomotive cylin ers employed. However, since my improved front frame structure, as herein described and claimed, has been actually used 7 and tested in connection with such a high powered consolidated locomotive construct-' ed. for the Delaware & Hudson Company and exhibited to the officers and directors ing' - stantial front framestructure is required.

In the locomotive of this new type, the

superheater as well as the direct pressure steam supply pipe connection with the high pressure cylinder and the receiver pipe connection between the hi h and low pressure cylinders, are arraugec exteriorly of theboiler or smokebox. In the drawing I have illustrated the superheater steam supply connection with the steam chest 19 of the highpressure cylinder at 24. 25 designates the outlet or exhaust from this steam chest which is connected by a receiver ipe extending over the smokebox with t e inlet connection 26 to the steam chest of the low pressure cylinder 18. The exhaust from this cylinder is conducted through the passage 27 formed in the body section 5 of the frontframe casting and through a suitable pipe connection to the exhaust nozzle withinthe smokebox of the locomotive. Thus, itwill be understood that a structure in legrally connecting two side frame members is provided with a cylindrical steam receiving chamber, and that said frame members extend forwardly and rearwardly from said structure. i One of the important features of in present improvements resides in the provision of a one-piece saddle or seat 28 for the cylindrical boiler shell at the upper end of the body 5 of the one-piece front frame.

Preferably, though not necessaril I de sign this boiler and smokebox sadt le as an integral partof the body structure 5 of the frame, and it will be noted that there is no direct connection of any kind between the cylinders and this boiler and smokebox saddle. Therefore, it will be seenthat I have materially simplified prior structures of this character of the types hereinbefore referred to so that it becomes possible to make the separate cylindersof one kind of metal and the locomotive frame and the boiler or smokebox saddle of a different kind of metal: Furthermore, by providing the body structure 5 of the frame as an integral partof the front frame casting,it is possible to pro vide direct liveand exhaust steam connecting passages "between the cylinder Valve Ice chest and the steam exhaust'pipe through i V instance in all cases it may not be found dewithout disturbing in any way the bolting connecting the saddle with the boiler wall, the bolting between the front frame and the rear frames, the bolting between the usual half saddle type of cylinders, the bolting between the half or full saddle type of cylinders and the front frame sections, or other connections, Thus it is seen that the operation of replacing a failed cylinder is greatly expedited and it becomes unnecessary to remove the numerous bolts connecting the same with the boiler or smokebox and independent front frame section which are more orcless diflicult of access. lVhen the new cylinder has been applied and secured in place by the bolts 28, it is firmly interlocked with the front frame by the lugs 22 seating in the recesses 21, said interlocking connections also operating to relieve the fastening bolts 23 of shearing strains.

v I have herein described the novel features of my present invention as used in connecto be entirely satisfactory. However, it is' evident that in the application of my improved front frame to various "different types of locomotives, minor mechanical changes may be found necessary. Thus for sii'able to form the boiler onsmoke boX saddle 28 as an integral'part of the frame casting, and it will be apparent that in suchinstances this one pi'ec'e saddle for the boiler or smoke box may be cast separately and ri idly bolted, keyed and secured upon the upper end of the body section 5 of the frontframe. Similarly, as to the several other structural parts of my new locomotive front frame, it will be manifest that the same might be exemplified in numerous other forms, and I accordingly reserve the privilege of adopting all such legitimate changes in the form, :onstruction and relative arrangement of the several detail parts as may be fairly embodied within the spirit and scope of the invention as claimed;
