LOCOMOTIVE OR CAR BODY.

Application filed December 21, 1925. Serial No. 76,590.

My invention relates to locomotives or cars and particularly to features which pertain to the body structure thereof. For

raising and lowering the body of a locomotive or car, as for example by means of a crane, special provision is usually made in the construction of the body frame, particularly in the more heavy types, for the attachment of the lifting means and an object of my invention is the provision of improved features of this nature.

'My invention will be better understood from the following description taken in connection with the accompanying drawing, and its scope will be pointed out in the appended claims.

Referring to the drawing, Figure 1 is a side elevation of a locomotive involving my invention; Fig. 2 is a detail of the body frame structure; and Fig. 3 is a further detail thereof.

In the drawing, I have shown the locomotive body 1 supported by the trucks 2 and 3 which are pivoted together at 4. The supporting frame work of the body comprises essentially the fioor plate 5, top girder plates 6, brace bars 7, fillers 8, channels 9, channel plates 10, bolster bars 11 and center plates 12 all welded or riveted securely together. This built-up structure constitutes two longitudinal box girders 13 and two transverse bolsters 14, the lower plate of each bolster comprising the bolster bar 11 and the upper plate comprising floor plate 5 reinforced by the top girder plates'6, brace bars 7 and fillers 8. For use in raising or lowering the body relative to the trucks I have provided the bolsters with a lifting lug 15 at each end thereof and have secured the lugs to the bolsters in such a manner that they are enabled to resist the enormous strains imposed thereon when the body is suspended from these points. The lower member of the body bolster comprises the bolster bar 11, shown in detail in Fig. 3. Each end of this bar is divided longitudinally thereof, as for example, by sawing or burning so as to form an integral central portion 16 and two integral side portions 17 The two latter portions are bent up so that their ends lie adjacent the floor plate and are secured as by welding or riveting to the floor plate 5, to the brace bars 7 and to the upper end of the lifting lug 15. The central portion 16 of the bolster bar is secured to the lower end of the lifting lug and has its extreme end 18 turned u 3 to engage the outer edge of the lug.f A ange 19 on the lugassists in supporting the side angle 20 and forms a bearing for a lifting cable. It will thus be seen that in accordance with the construction which I-have shown and described, the lifting force applied to the lifting lug is applied through the bent-up portions 17 of the bolster bars to the bottom of the box girders and each lifting lug is secured at both ends to integral portions of the bolster bar.

l/Vhat I claim as new and desire to secure by Letters Patent of the United States is:

1. In a locomotive or car, a body frame comprising a bolster having spaced upper and lower plates, and a lifting lug secured v between said plates.

2. In a locomotive or car, a body frame includlng a bolster having spaced upper and lower plates, and a lifting lug secured between the plates, one of said plates having integral portions to which opposite ends of the lug are secured.

3. In a locomotive or car, a body frame including a bolster having upper and lower plates, a lifting lug secured to the upper plate, said lower plate having an integral portion extending upward and secured to the upper end of said lug and having an integral portion extending outward and secured to the lower end of said lug.

4. In a locomotive or car, a body frame including a transverse bolster having spaced upper and lower plates and a lifting lug having its upper and lower ends secured respectively to said plates, said lower plate having an integral end portion extending upward and secured to the upper end of said lug. 5. In a locomotive orcar, a transverse body bolster comprising an upper plate, and a lower plate spaced therefrom, and a lifting lug secured at its opposite ends respectively to said upper and lower plates, said lower plate being divided longitudinally at one end to form a plurality of end portions, one of said end portions extending up and being secured to the upper end of the lifting g- 4 6. In a locomotive'or car, a transverse body bolster comprising an upper plate, and

upper plate, said bolster bar having longitudinal openings extending inwardly from the end thereof forming a plurality of integral end portions, one of said end portions being secured to the upper end of the lifting lug and another of the end portions being secured to the lower end of the lifting lug.

7. In a locomotive or car, a body frame including longitudinal girders, and a transverse body bolster comprising an upper plate anda bolster bar forming a lower plate, said plates beingrigidly secured to said girders, said bolster bar being divided longitudinally at each end to form a central and tWo side portions, and alifting lug, said lug being secured at its lower end to said central portion and being secured at its up per end to said side portions and to saidupper plate.

In witnesswhereof. I have hereunto set 20 my hand this 19th day of Deeember, 1925. BERTON A; GARRETT.
