Specification of Letters Patent.

Application led November 11, 1913. i Serial No. 800,324.

`.its driving box 'so that certain ditliculties may be overcome and objectionable features eliminated in the driving box construction of locomotives in modern use.

In the process of assembling the parts of a locomotive driving box, the bearing is pressed into the box with a power of' from twenty-five to thirty-tive tons pressure before the ends of the box are slotted. This excessive ressure of course spreads or expandsf the box to a certain extent. After beinglslo'tted the boxwith its bearing is driven into the frame and the cellar is then applied.

When the locomotive is first placed 1n service the parts o the bearing including the box v and cellar are expanded due to heat, but after the journal has been running for some time the parts are smoothed and friction is reduced and consequently the heat. The

parts now contract and the result is that the cellar is held so tightly in the box that much time and labor are consumed in withdrawingghe cellar from the box, and .frequently it l comes necessary to break the cellar before itcan be removed from the box, which of course renders the cellar worthless for further use and requires the services of a new cellar. This o eration is necessary with the renewal of t e bearing brasses and many times the cellar.l and box are both ruined when dropping thewheels to furnish new brasses. v By Vthe utilization of my improved cellar these and other diiiiculties are `removed as will be hereiijafter pointed out.

In the accompanying drawings ,I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of my invention.

The invention is applicable for use with the standard drivingbox for looomotives'now in use and the box is equipped withthe invention by' the addition `of drilling two holes therein as will be described. The box 1, journal bearing o-r brass 2 and journal 3 are o f usual type, and t-he box is fitted with a pair of studs 4, 4, projecting from the front wall thcreofnear the bottom. 'Ihese studs arer tapped into holes that are drilled j into t-he metall of the box.l and are provided with a slot 5 for a cotter pin ti.

The cellar '7 is clearly shown in Fig. 3 where it is apparent that it has an open bottom and its front and rear walls are curved for the journal. On the front wall of the cellar are spaced two ribs 8 which are undercut on their adjoining faces to provide a. dovetail groove therebetween which extends from side to side of the cellar. rlhis groove is for the accommodation of the locking key 9 which is formed with beveled edges com- Elementary to the dovetail groove, and the ey also is slotted at 10, 10, to pass over the studs 4 and perforated at 11 to pass over a box invola'ing my invention. Fig. 2 is a Fig. 6 is v stud 12 fixed in the front of the cellar, and .A

- As' illustrated in the. drawings, the cellar is in two pieces, lthe bottom being formed of a base plate 12 having a rear upwardly projecting flange 13 to lfit into a recess 14 in the cellar, and a pair of ribs 15', 15, extending vacross the bottom, and perforated for the two locking keys 16, 16 passed therethrough and through the perforated lugs 17, 17 of the box. s a safety device, after the parte are in place, the cellar and' its bottom are held together by l means'of the bolt 18, which` is passed through the perforated lugs 19, 20` on 'the cellar and bottomrrespectivel In assemblingthe parts after t e brass .has been located and the box placed 'in situ,

los

the base or bottom only of the cellar is now forced in between the ends of the box and the locking bars or keys 16 are located. The

5 Figure 1 is a front elevation of a vjournal .cellar is now ready to he placed, having pre7 110 It Will be understood that the cellar base' holds the box slightly distended, and the cellar is free to pass into'the box, not only on account of this slight distention, but because -it is purposely made of less dimensions and has a loose fit in the box. .The slotted ends of the key pass overthe studs 4 and the cotters 6 prevent displacement of the key. As before stated the bolt 18 may now be secured in lace.

henever it is necessary to remove the brasses, the cellar is first removedby withdrawing the bolt 18 and cotters 6 and then bodily withdrawing the cellar. The two keys 16, are then removed and the space formerly occupied by the cellar provides an opening for a jack by means of which the box is spread suiiciently to permit the withdra-Wal of the base of the cellar. The removal of the cellar permits access to the hub face of the driving wheels so that they maybe'inspected at frequent intervals, and it will be apparent that the cellar can be removed as easily under the locomotive, as if it were entirely free therefrom.

In Fig. y6- I .have illustrated a cellar 7" having a closed bottom 7a. This type of cellar is employed when liquid oil 1s usedas the lubricant and the type of box shown in Fig. 8, without the bottom, is usually employed whenthe lubricant is made up of grease.

From the above description taken in con` nection with my drawings it is evident that Ihave provided an improved cellar that will accomplish the purposes and objects. of my invention in a comparatively perfect manner.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is 1. Thecombination with a driving box, of a cellar having a air of transversely ex- `tending horizontal y undercut ribs, of a locking key having beveled edges to t between said ribs and havin over the driving box, stu s projecting vfrom the :driving box, said key having, perforationsto fit over said studs and means for4 locking the key on the studs.

2. The combination with a driving box, and a cellar having a pair of spaced retainingribs, of a key dove tail in cross-section located between said ribs with its ends extending over the adjoining edges of the driving box, and means for securing said key to the driving box. 4

In testimony whereof I affix my signature in presence of two witnesses.
