Patented Apr. 14, 1931 UNITED STATES PATENT OFFICE WILLIAIVI C. ARMSTRONG, OF SPRINGFIELD, OHIO, ASSIGNOR TO THE CERAMIC MA- CHINERY COMPANY, OF HAMILTON, OHIO, A CORPORATION OF OHIO GASOLINE-ENGINE LOCOMOTIVE Application filed January 23, 1928.

This invention relates to improvements in' gasoline engine locomotives of the type and character set forth inmy copending application filed February 6, 1928, Serial No. 252,122, now Patent No. 1,7 65,559 of June 24.,1930.

I The present improvements consist, first, ofthemanner of-mounting the journal boxes and Wheel axles in the general frame; second, in the position and manner of mounting supporting-skids in the general frame; third, in the manner of spacing and positioning track wheels on their axles to adapt the same general frame to use on railways of different gauges; and fourth, in the manner of mounting andjsecuring the sprocket wheels on the axles. 1

In the accompanying drawings,

Figure 1 is a partial sectional view and elevation of the general frame showing the manner of mounting the journal boxes and supporting skids and is taken on the line 1-1 of Fig. 2. Figure 2 is a vertical transverse sectional View taken on the line 2-2 of Figure 1 showing the manner of mounting the journal boxes, of spacing the track wheels and mounting the sprocket wheels.

Figure 3 is a detail sectional view taken on theline 33 of Figure 1 illustrating features in the mounting of the journal boxes.

Figure 4: is asectional view through one of the track wheels showing a form of spacing sleeve: for positioning the ground wheels to travel on a track of differentgauge from thatsho-wn in Figure 2.

Figure 5 is a side elevation of the general frame,'thejournal boxes and the skids. Figure 6 isa partial sectional view and elevation showing the sprocket wheels halved and their mounting, and taken on the line 6 6 of Figure 2.

In the drawings, the numeral 1 designates the general frame of the character set forth in my copending application above cited. This frame is formed with arches 2, leaving vertical walls 3 on'each side. In these walls are entered sturdy stop screw bolts 1' adapted to'lpermit thefgeneral frame to Work up and downwith reference 'to the journal boxes Serial No. 248,661.

generally indicated at 5. The boxes are formed of a casting, rectangular in shape. as best shown in Figure 2. On their sides they have ribs 6 which occupy the space between the upper and lower sets of stops 4, as best seen in Fig. 1. These ribs are preferably cast on the box walls. In this way the boxes and the general frame are allowed relative movement in the vertical, according to the weight the frame is carrying or the jolting that may cause the frame to move up and down with reference to the boxes, the latter being supported on the wheel axles 7, as clearly seen in Fig. 2.

Flanges 8 cast on the boxes serve the dou ble purpose of forming a shoulder back of the leaf springs 9 and back of the ledges 10 on the general frame as shown in Fig. 3. In this way the boxes are prevented from outward movement beyond the frame other than their normal position. The boxes are prevented from inward movement on the frame by the shoulders 11 on the axles.

Caps 12 are secured to the boxes by screws or bolts indicated at 13, and may be removed for access to the ball bearing mountings 13a for purposes of lubrication.

Thus it will be understood that my journal boxes are carried in the manner stated by the general frame and are capable of permitting the frame to have up and down movement to the extent of the travel between the ribs 6 and the stops 4, while the boxes are prevented fromtransverse displacement by the ledges 8 and shoulders 11.

The numeral 14 designates integral portions of the general frame fashioned to constitute seats 15 within which. are fitted supporting skids indicated at 16. These skids are firmly fitted in the seats 15 and are made, preferably, of wood, being in the nature. of heavy timbers. They overlie the rails and when the wheels are on the rails the skids are above and free of any contact with the rails, while if the wheels are derailed then the skids come down on the rails and perform the double oflice of supporting the locomotive and of acting as brakes to overcome the momentum, which arises from the frictional engagement of the supporting skids on the treads of the rails. In locomotives of the character here referred to, these skids are very important and valuable. They prevent breakage should the locomotive drop down due to the derailment of the wheels, at which time the skids act as supports and brakes. And itwill be observed that the seats are formed by the port-ions 14 which are integral with the general frame.

I Referring to that feature of the invention which relates to'spacing the track wheels at different distances apart to accommodate them to tracks of different gauges, whether more or less wide or more or less narrow as compared with any given standard. This feature of the invention is carried out by the use and application of. spacing sleeves indicated at 17, being castings of cup-like formation so as to comprise a hub 18, which'fits upon the axle and a flange 19 which fits within the rim 20 of the wheel and is bolted to the web of the wheel as indicated at 21.

sleeves, one between the journal box and the wheel, and the other between the wheel and a shoulder on the axle indicated at 22.

The lateral dimensions of the outer spacing sleeve 17 may be, as shown in Fig. 2, for a gauge ofa certain width, or may be less in extent for some other gauge of greater width.

In the illustration in Fig. 2, the inner and outer spacing sleeves 17 are together of sufficient lateral dimension to occupy the space between the inner face of the journal boxes and the shoulders 22. I

In the illustration given in Fig. 4, the lateral dimension of the outer spacing sleeve 17 a is shortened, and the lateral dimension of the inner spacing sleeve is increased, so to position thetrack wheel 23 further out on the axle for a wider gauge of track.

Thus it will be understood that by the use of my interchangeable spacing sleeves, I can utilize a general frame of fixed dimensions With'various widths of track gauge by thus being able to position the track wheels appropriately on the axles for the particular gauge.

With reference to the manner of mounting the sprocket wheels, it will be observed that I have fashioned the inner spacing sleeves 1701' 17 a, as the case may be, with circular rims 24 and make the sprocket wheels 25 each in thenature of annulus" 26 whose interior diameter is equal to the exterior diameter of the: spacing sleeve, and whose inner face abuts against the rim 24:. Each sprocket is made inhalves so as to be readily applied over the spacing sleeve as'indicated in F ig. 5.

Through bolts 27 are employed 'to secure the sprockets to the sleeve by passing through thesprockets and the rim 24.

It will now be understood that in case of breakage of a. sprocket wheel, or other injury, as well as in the case of assembling the machine, this construction and arrangement of the sprocket wheels and the spacing sleeves make the work feasible and the application and removal of the sprockets an easy task. These sprockets are, of course, driven by sprocket chains operated by the engine, but that feature forms no part of the present invention.

The inside cup or bell-shaped casting gives additional stren h to the axle as it'extends to or near to the journalbox bearing in which the axle is mounted. The power is applied directly to the flanges of the wheels on the inner sides inside of the wheels. The hubs the sprockets are attached to are a part of the bell-shaped casting.

Greatly increased leverage to drive the locomotive is secured by this construction as the leverage isnot less than eighteen incheswhereas in previous constructions the maximum leverage to be secured from. such construction was from three to five inches.

I have eliminated all keys and key seats which weaken the construction of the axle atthe'key seat. Furthermore in previous constructions the wheels became'lose on the axle, whereas with my construction the wheels are firmly held on the axle and the axle is not weakened but it is strengthened.

By using the proposed bell-shaped castings, I provide a truss-likestructure which greatly strengthens the axle where the maximum strain of weight support and drive is app i Finally, it will be observed that I have combined with my general frame, which is in each instance of fixed dimensions, these four vital accessories to this frame, namely, the journal boxes and the manner of mounting them ;'the supporting skids and the manner of mounting them; the track wheels and the manner of spacing them at different distances apart to adapt them to different track gauges; and the mannerof constructing and mounting the sprocket wheels; all of which features, together with said frame, are and have been the. subject of manufacture, sale and commercial use."

I desire to' comprehend within my invention such modifications as may be clearly embraced within my claims and the scope of my invention. e

Having thus fully described my invention what I claim as new anddesire' to secure by Letters Patent, is: s s

1'. In a locomotive, the combination with a main frame fashioned with arches for the reception of journal boxes, and stops positioned in said arches a pair on each side, of journal boxes, each having stop ribs adapted to occupy positions between the stops to permit and limit the relative movement of the frame and boxes. I
