GEARED LOCOMOTIVE FRAME AND .BOILER SUPPORT.

Appueation mea october 5, 1922. serial No. 592,481.A

To all whom t may concorre.'-

Be it known that we. IVILLIAM E. 700D- ARD and I'Iiinnnn'r IV. SNYDER, both citizens of the United States, respectively residing at Forest Hills, in the county of Queens and State of New York, and at Lima, in the county of JAllen and State of Ohio, have invented certain new and useful Improvements in Geared Locomotive Frames and Boiler Supports, of which the following` is a specification. n

This invention relates to frames and boiler supports for geared locomotives such, for example, as those of the Shay type.

The frames heretofore used for geared locomotives have been composed of side and cross members, the side members usually being of I-beam construction. One of the difficulties encountered in connection with this construction has been that the side members of the frame cover up the stay bolts in the water legs of the boiler, rendering them inaccessible for inspection or repair. An attempt has been made to provide inspection for the stay bolts by drilling a number of holes through the side frame members but in practice this expedient has not proven to be successful because of the difficulty of registering the holes in the frames with the stay bolts in theboilerand also because of the fact that these holes offer ycomparatively poor access to the bolts.

In addition, the' boiler has been supported by pads studded to the side members of the fire box and clips bolted to the top of the frame. The pads cover up. a number of the stay bolts and, moreover, the type of'construction often leads to breakage of or leakage at the studs which attach the pads to the boiler. i

It is one of the primary objects of our invention to provide an improved frame which overcomes the difficulty of stay-bolt inspection and renewal; and which also provides an improved arrangement of boiler support and obviates the diiiiculty inl this regard heretofore noted. l

Our invention also contemplates an improved manner of *supporting the boiler which is more effective and is least affected by expansion and contractionof the boiler.

The foregoing, together with such other objects and advantages as may hereinafter appear or are incident to the invention shown and claimed, we accomplish by means of a construction which we Ahave illustrated in preferred form in thev accompanying drawings, wherein V F ig.A 1 illustrates ithe improved frame in side elevation, the other locomotive parts being indicated in dotted lines; Fig. Qfis a vplan view of the frame shown in Fig. 1:

Fig. 3 isl an enlarged section taken'on the line 3--3 of.v Fig. 2; Fig. l is a` section taken on the'line 4.-4 of Fig. 3; and'Fig. 5 isa section taken on the line 5v 5 of Fig. 3.

Referring now to Fig. 1,.a typical Shay locomotive is'indicated in dotted lines, in so far `as superstructure and driving mechanism is concerned. The frame of the locomotive, indicated as a whole by the reference character A, however, is composed; of the following parts: A pair of sideplates 7, of girder form, are connected at front and rear by ties such as cross ties 8 and 9 and, intermediate their ends, by combined cross ties or braces) and boiler supports B and C. The side plates 7 each have an angle 10 secured thereto4 along their upper edges-on the outer face and with a similarly disposed angle 11 at their lower edge., In their intermediate or swell portion, the side plates are cut away to provide a large opening 12, coming opposite thesides of the fire boXD, exposing practically all of the stay bolts and making them readily accessible for inspection and renewal.` To compensate for the material cut away in the side plates, i. e.. in the web of the girder, a plate 13 is added to the top and a plate 14 tothe bottom of each girder or side member, such platesbeing suitably riveted or otherwise secured. Additional' strength is had by virtue o-f the angles 15 of which there is one secured to the innerjface of each side plate at the lower edge. Theplates 1,4:l are coextensive'with the anglesy 11 and A15. The'angles 15 'serve an additional function in that they act as a footing for'the boiler. supports B and G,

The combined cross braces and boiler supports B and C will now be described. The member B comprises a steel casting which is substantially angle-shaped in cross section and is provided with strengthening ribs 16, a reinforcing bead 17 and with suitable iianges 18" and '.19 for .attachment to the angles 15 and the side plates 7, respectively. The flanges 19 are reinforced by the fins Q0. Pads 21 are provided for the shoes 23 (see Fig. 3). These shoes are provided in order to accommodate for small irregularities in boiler construction, the shoes being fitted in the erecting shop between the boiler support cross ties and the boiler mud ring 24. The topy portions ofthe shoes are of excess thickness to allow for the machining necessary to compensate for such irregularities. .It will be seen, therefore, that in contradistinction to the old practice, by our arrangement the lire box of the boiler is carried directly on the member B` through the medium of the .shoes 23 on which the mud ring 24 rests. Bolts 25 secure the mud ring to the member B.

Thecombined cross brace and boiler sup- -port C comprises a casting rextending between the side members and provided with flanges 26 and 27 for bolting to the vangles 15 and the side plates, respectively. This casting is provided with a ledge 28 at the bottom for carrying an expansion bearer 29 such as ordinarily used vin.locomotive', practice. The expansion memheryis bolted to the cross brace C by means ofthe bolts 3() vand the rear portion of the=mud ring is secured to the upper lportion ofthe expansion bearer. i

By this arrangement. the boiler is supported through themcdiun ofthe mud ring and the use of attachingbrackets and clips yresting on top ofthe side platesiand studded to the shell of the boiler is obviated andthe disadvantages incident thereto overcome. There the boiler is supported by clips or brackets, as above described, heavy strains are placed on the attaching studs because of the expansion and contraction and weaving of the boiler, and this, among other things, causes leakage and breakage of the points of attachment.` The combined boiler supports and cross braces connecttheside plates adjacent .the ends ofthe openings therein, thus `affording strength at such points.

The frontend of the `boiler is supported froma cross tie 8 lin the usual manner with freedom for longitudinal movement Zbut `no vertical or lateral motion. The'lvpoints of boiler support are. therefore, low, whic-h also presents some featuresof advantage.

`We claim:

l. The combination in a geared loco-motive of a boiler having a mud ring, a frame, and means on the mud ring whereby the boiler is supported on the frame by themud ring, themud ring beingsecuredto the frame with expansionV from the pointof attachment.

2. In a. geared locomotive, the combination of a boiler having-a `mud ring and a frame, the mud ring being carried on the frame, the mud ring being secured to the frame with expansion from the point of attachment.v

bers and combined `cross brace and boiler supporting members connecting the lower portions of the side members, the mud ring being carried on said cross brace and boiler supporting members.

6. In a geared locomotive, the combina tion of a boiler having a fire box `and a frame composed of side members each cut away to provide an opening comingopposite a. side of the fire box to expose stay bolts.

7. In a geared locomotive, a supporting frame comprising girdeiflike side. members cut away to provide an opening-oppositefthe Sides of the fire boxand the boiler'andprovided with reinforcing means compensating for the-materialcut away.

8. In a geared locomotive, a supporting frame comprising side plates having .a reinforcing angle at the top and bottom, the side plates being cut away to provide openings coming opposite the sides of vthe fire box and the boiler, and additional reinforc ing means at topand bottom compensating for the material cut away.

9. In a `geared locomotive, a .supporting frame comprising side members vlhaving combined reinforcing and foot members, and boiler supports carried on said members.

10. =In a geared locomotive, a frame comprisingside plateseach having a combined reinforcing and foot member, and combined cross braces and `boiler supports carried on said members.

1l. Ina geared locomotive, a frame comprising side members each having a kcoinbined reinforcing and foot member, and a combined cross brace and boiler support carried on said foot members.

12. In a gea-red locomotive, a supporting frame comprising side girders each having an opening therein to .expose the sides of there boX and the boiler, and cross members connecting the side members at points near said openings.

In testimony whereof, we have hereunto signed our names.
