.ments in compound locomotives, especially of the type in which the locomotive boiler extends over two frames, which: are coupled together by an articulated joint. In this type of locomotive the usual practice has been to use anordinary tender and these'loi comotives are now of such size thatthe tender must be of an appropriate size and, con-' tofore used. I

One object of the invention is to utilize a large portion, or all, of the weight of the tender for purposes of adhesion and traction, as well as-the weight of thelocomotive proper. This object I attain by mounting the tender on a driven element correspond- Y ing in many parts to the two elements on which the locomotive boiler is mounted so that, in the present instance, there are three independent driving units to form a triple, compound locomotive.

Afurther object of the invention is to desi 11 the locomotive so that all the cylinders Wlll preferably be of the same diameter and to direct the exhaust from the high pressure cylinder to the two low pressure cylinders, one at the forward end of the locomotive and the other at the tender.

In the accompanying drawings :Figure 1, is a side view, .in outline, illustrating my invention; Figs. 2 to 5, inclusive, illustrate fractions of the locomotive, in the order of numbering, drawn to'an enlarged scale; Fig. 6, -is a transverse, "sectional view on the line 55, Fig. 2; Fig. 7, is a transverse, sectional view on the line 6--6, Fig. 3, and Fig. 8, is a rear elevation.

Referring to the drawings, A is the forward frame of the locomotlve and A is the intermediate frame. These two frames are connected by an articulated or hinged joint at a, which is the common method of connecting the two frames of an ordinary articulated locomotive.

A is the rear frame of the locomotive, connected to the intermediate frame A by an articulated joint a, which may be similar to the joint a. Mounted rigidly, in the present instance, upon the intermediate frame A is the boiler B. .This boiler extends over the forward frame A and has a sliding support thereon; so that, when the locomotive is turning curves, the frame A may have a lateral movement independently of the boiler B and the intermedlate frame A. At the rear endof the boiler is the usual cab b for the engine driver and this cab terminates substantially on a line with the articulated joint coupling the. intermediate frame A with the rear frame A". The rear frame A of the locomotive is, in fact, the tender of the locomotive, having the tank 0 and the space for the fuel.

The boiler, while shown as a continuous boiler rigidl supported ofithe intermediate frame and reely overhanging the forward frame, may be made in two sections; each section rigidly mounted on its frame and connected together by a flexible joint. The boiler may be used entirely for the generation of steam, or it may be used partly for the generation of steam and partly for superheating, or heating the feed water with which the boiler is supplied.

D are the hi h pressure cylinders, one located on each side of the intermediate frame A of the locomotive and E and F are the low pressure cylinders, one on each side of the frames A and A The cylinders D have valve chests of the ordinary type and steam is supplied to the cylinders directly from the steam dome b of the locomotive boiler through the pipes b one at each side of the boiler. The exhaust ports of the cylinders D communicate with the steam space of the two low pressure cylinders E and Fvon each side of the locomotive and e is a pipe leading to the steam space of the cylinder E. f is apipe leading. to the steam space of the cylinder F. The pipe 6 is preferably coupled on a line with the pivot a by a ball and from the cylinder D, while the pipe f, which is on the tender frame A, is connected to a fixed pipe f in the intermediate frame A by a flexible connection f on a line with the pivot a. By this construction, live steam is supplied to the cylinders D on the intermediate frame and the exhaust steam from these cylinders is divided; part passing to the low pressure cylinder E on the forward frame of the locomotive, and part passing to the. cylinder F on the rear or tender frame of the locomotive. The exhaust from the low pressure ,cylinder E. passes through a pipe 9 into the smoke box and escapes through the usual nozzle direct to the stack, while the exhaust from the cylinder F passes through a pipe H projecting np wa rdly at the rear of the tender and this pipe terminates at a point preferably above the top of the tender, and, in fact, above the top of the cars ofthe train.

.In the present instance, the intermediate frame A is mounted on eight driving wheels at, four on each side, and these driv- I ing wheels are all coupled to the piston of the engine in the ordinary manner. The

front frame is mounted on eight driving wheels m-four on a side-and a two wheel radial truck of the ordinary type. The rear tender frame is also mounted. on eight wheels p and connected in the ordinary manner to the piston in the cylinderF and at the rear of the frame is a two-wheel radial truck 7), similar to the truck m in the present instance. The ordina type of equalizing beams is used throug out. The valve motion forthe three sets of cylinders is operated by means of a power mechanism controlled from the cab so that all the valve motions can be operated uniformly and together.

The locomotive, as illustrated, shows an equal number of drivi truck at each end of the cylinders of the same size, which gives a ratio of com ounding 2 and it is evident that these cy inders may be made of different diameters and that any combination of driving wheels and truck Wheels maybe used'in order to obtain any particular weight and'arrangement of engine desired.

The-engine can be run either forward or backward with equal effectiveness, as the rear frame is coupled to the intermediate frame in the same manner as the forward frame. 1 The boiler can be made, as above'remarked, in a single shell and has flexible or articulated steam pipes so that when steam at a greatly reduced pressure is used the difficulty of maintaining the same is proportionately reduced.

In order to provide means for applying sand to the tracks, when the locomotive is running backward, I provide, in the present instance, a sand box 9 at the rear of the tender, and this sand box preferably sur-.

rounds the exhaust pipe, or is located in contact with one side of the exhaust pipe, as clearly shown in Fig. 8, so as to heat the sand to the proper temperature.

It will be understood that in some instances the high pressure steam may be used in all of the cylinders, if considered desirable,

wheels under each of the four-sections w1th a twowheeled of the locomotive being. similar to thehigh pressure cylinderthus economizing considerably n the construction and gaining a result which will utilize a large proportion of adhesion .and traction, as well as the weight of the locomotive proper.

'When I' use the term tender asapplied to. the locomotive, I mean an. independent frame connected to thelocomotive having either the usual water-tank and fuel connection, or any'equivalent, whereby the -frame is sufiiciently weighted to give the driving wheels the necessary adhesion, and I may, in some instances, so construct the 10- comotive that a single frame carries the boiler, driven by high pressure or compound cylinders and a tender frame independently driven and having low pressure cylinders receiving steam from either the high pressure cylinder or the low pressure cylinder of the locomotive frame.

In some instances, where a large engine is desired, more than three frames may be used, each independently driven, without departing from the essential features of the invention.

The exhaust from the cylinders mounted on the tender frame may be allowed to escape to the atmosphere, or may be utilized to heat the train, or to heat the tender water, or for other purposes where a moderate heat is desired. If the tender water is heated a pump will then be used to supply the boiler,

connected by ball joints and one o the sec-- tions is arranged to slide in the other.

Other connectionsmay be used without departing from the essential features of the invention.
