SPECIFICATION forming part of Letters Patent No. 667,342, dated February 5, 1901 Application filed October 19, 1900-. Serial No. 33,552. KNo model.)

To fl, Hill/077D it rim/,7 concern.-

Be it known that I, JAMES E. SAGUE, a citizen of the United States, residing at Schenectady, in the county of Schenectady and State of New York, have invented certain new and useful Improvements in Locomotives,of which the following is a specification.

This invention relates to that class of 1000- motives in which the fire-box is made of extra width in order to obtain an ample grate area without necessarily increasing the length thereof. It is desirable thatthe fire-box should be located at the rear of the locomotive in order that the fireman and engineer may be together. In such locomotives it is necessary to provide one or more pairs of supporting or trailing wheels under the fire-box, and in order to obtain the greatest width of fire-box and ash-pan the sides of the ash-pan should be as close as possible to the inner sides of the trailing wheels. In the locomotive hereinafter described the axle-boxes of the trailing wheels are arranged outside the truckframe, by which construction the sides of the ash-pan may be arranged close to the inner sides of the trailing Wheels, thus giving to the ash-pan a greater width than could be obtained where the axle-boxes are arranged inside the wheels. Such an arrangement also prevents the journals of the trailing wheels from being heated by close proximity to the ash-pan. The bearings are readily accessible for oiling, 850., and the lateral distance between the points of support is increased, thus making the engine much steadier and freer from a tendency to roll, as is the case where the axle-boxes are arranged inside the wheels.

While, broadly stated, it is not new to arrange the axle-boxes of the trailers outside the wheels, it is new to so arrange the axleboxes in connection with improved devices employed by me for equalizing the weight, as hereinafterdescribed. Theequalizingmechanism is of an improved construction and arranged in an improved way. Springs are attached to the axle-boxes of the driving-wheels and to the trailers, and they are connected together by links and levers in such manner as to properly distribute the weight. The axle-boxes of the driving-wheels are arranged inside the truck-frame, and special mechanism is employed by me for connecting the springs attached to the axle boxes of the drivers with the springs attached to the axleboxes of the trailing wheels, which, as before stated, are arranged outside the truck-frame.

The details of construction will be hereinafter more fully described.

The subject-matter deemed novel will be setforth in the claims.

In the accompanying drawings, Figure 1 shows a side elevation of a locomotive embodying my present invention. Fig. 2 is a plan view of the truck thereof. Fig. 3 is a detail view showing particularly the manner of connecting the springs of the drivers with the springs of the trailing wheels. Fig. 4 is a detail plan view of this mechanism, and Fig. 5 shows a transverse section on the line 5 5 of Fig. 3.

The boiler A and cab B, with their appurtenances, are of usual construction. The firebox A and ash-pan A are mounted on a frame supported on driving wheels 0, trailing wheels D, and pilotwheels E. The main frameis preferably continuous, the front ends of the side pieces H thereof being secured to abuffer F,while the rear ends are connected by a cross-frame G. The frame H is formed with pedestals or guides H H for the boxes 0 of the driving-wheels. Outside frame pieces or plates J are provided, and each has a guide or pedestal cl extending over the axle-box of the corresponding trailer. These frame pieces or plates J are arranged outside the vertical plane of the trailing wheels over the trailing axle, and the rear ends of the frame-pieces H also extend over the trailing axle inside the wheels, as indicated, for instance, in Fig. 2. Filling-pieces K are interposed between the outside frame-pieces J and the adjacent sides of the frame-pieces H and are bolted thereto. The outside frame-pieces J and the rear ends of the main frame-pieces H are also connected together between the cross-frame G and the trailing axle by means of bolts. Fillingpieces G are interposed between the rear ends of the outside pieces J and the rear ends of the frame-pieces H and are securely bolted thereto and to the cross-frame G, as indicated.

The construction which I have just described is not herein claimed as part of my present invention, as substantially the same construction is shown and claimed in my application for patent, Serial No. 26,779, filed August 13, 1900. That application, however, shows different mechanism for equalizing the weight or connecting the springs of the drivers with the springs of the trailing wheels. In the presentinstance a spring M is mounted on top of the axle-box of each trailing wheel. The rear end of each spring is connected with a corresponding outside frame piece J by means of a link m. The front end of each spring M is connected by means of a link N with a lever O, pivoted at 0 to a hanger P, depending from the truck-frame. The lever O is diagonally arranged. Its rear end, where it is connected to the link N, is directly under the front end of the spring M. The front end of the lever 0, where it is connected to the spring S of the rear driving-wheel, is directly under the rear end of the spring S. Thus the lever 0 extends from the outside of the frame-piece J to the inside of the adjacent frame-piece H and beneath these framepieces. The link N, it will be observed, is twisted at n in order to obtain a proper pivotal connection at this end. The front end of the lever 0 may be slightly bent at 0 in order to obtain a pivotal connection with the lower ends of the links T, which connect the front end of the lever -O with the rear end of the spring S of the rear driving-wheel.

In the present instance the springs S Sare mounted on top of the axle boxes of the drivingwheels; but they may be otherwise attached thereto. Where they are mounted as shown in the drawings, the front end of the rear spring S is connected by means of links U with a lever U, pivoted to the main frame. The front end of the lever U is connected by links '11 with the rear end of the spring S. The front end of the spring S is connected by means of links a with a bracket 11. on the truck-frame. The arrangement on opposite sides of the truck is precisely thenecessary to reduce the area of the ash-pan to accommodate the trailing axle.

The mechanism is simple and most effi ciently provides for the equalization of the weight in that class of'locoinotives embodying a wide fire-box with the axle-boxes of the trailing-wheels arranged in a different vertical plane from the axle-boxes of the drivingwheels.

vI claim as my invention 1. The combination of the driving-wheels, their axles, the axle-boxes thereof arranged inside the wheels, the trailing wheels, their axles, the axle-boxes thereof arranged outside the wheels, springs attached to the axleboxes of the driving-wheels and to the axleboxes of the trailing wheels, the truck-frame, diagonally-arranged levers pivoted in bearings thereon, and connections between the springs of the trailing wheels and drivingwheels, and said diagonally-arranged levers.

2. The combination of the driving-wheels, their axles, the axle-boxes thereof arranged inside the wheels, the trailing wheels, their axles, the axle-boxes thereof arranged outside the wheels, springs attached to the axleboxes of the driving-wheels and to the axleboxes of the trailing wheels, the truck-frame, levers pivoted thereto, and extending diagonally'beneath the sides of the frame, links arranged outside the frame connecting the springs of the trailing wheels with the diagonally-arranged levers, and links inside the frame connecting the diagonally arranged levers with the springs of the driving-wheels.

3. The combination of the driving-wheels, their axles, the axle-boxes thereof, arranged inside the wheels, the trailing wheels, their axles, the axle-boxes thereof, arranged outside the wheels, springs attached to the axleboxes of the driving-wheels, and to the axleboxes of the trailing wheels, the main truckframe, the outside frame-pieces connected therewith, the diagonally-arranged levers, the rear ends of which are arranged outside the outside frame-pieces and which are con nected with the springs of the trailing wheels, and connections between the front ends of the diagonally-arranged levers and the springs of the driving-wheels.

In testimony whereof I have hereunto subscribed my name.
