' This invention relatesv to journal boxes and particularly to lubricant cellars for journal boxes. f The Object of the present invention is to 5 provide aj o-urnal box embodying a cellar for lubricant and wasteor other packing, which i simple and inexpensive construction-and will be sturdy and dependable in operation. 1

Where a locomotive is making a long run, .itjisi'necessary at intervals, to stop and replace the ournal. packing and replenish the lubricant. As thetime-of such stops is ordinarily limited, journal boxes embodying the present invention are especially advantageous inthis instance, in that they permit the packing and lubricant to be replacedin "the sh ortest possible period oftime. The invention is illustrated in the accompanying drawingfin' which: Figure 1 is a view in elevation. of a part of a locomotive truck showing a journal box embodying the *instant'invention, applied thereto; Fig. 2 is a sectional view on the line II II of Fig. 1; Fig. 3 isan enlarged longitudinal sectional view of the lubricant cellar, on the line III- '-I1I of Fig. 4; Fig. 4,011 the left side, isa sectional view-on theline IV-JV of Fig. 3, and.on tlie right side is an end View of the cellar shown'inFig. 3, parts of the journal box being'shown at the opposite sides of the cellar ;-Fig. 5 is an enlarged side view of the gjoumalb x cellar, showing a part of the journal box, axle, and wheel, with the axle journalin position in thebox and the lubricant cellar in open position; and Fig. 6 is a planview of the lubricant cellar in closed position withinthe journal box.

Y y In the practice of he inven ion, referring descriptively to the specific embodiment thereof, which is herein exemplified as applied to a ournalbox 1', thenpper portion of I Whic'h'isof theusu'al constructiomthe jour- :are formed with semi-circular depressions passedthrough said handle and a head25 is nal box is shown applied to a journalQ, of an axle 3, having wheels 4 at its ends (only a part of the axle and one wheel b'eing'sho-Wn). The journal box is held in position inlthe usual manner between a' pair of depending pedestal jaws 5 of a frame member A lubricant cellar 7 is providedipforthe bottom of. the journal box, and comprises sidewalls 8, rear and front walls, 9 and 10, respectively, and a bottom 11, forming ,a

; su'bst,antially, box-shaped construction ,(the right end as shown in Fig. 1 being considered the front for the purpose of the description) The rear and front Walls 9:and10, 5

9aand100; respectively, in theirupper edges,

,the depressions conforming to theshape of the axle journal2. Thelower edges of. the side walls 8. are inset at 12, providing shoulders 13 The side walls 14'of the journal box, are formed. at their lower ends with longitudinal inward extensions 15 which provide ,seats 16, and longitudinal depressions-or slots 17 are formed in the inner faces of theside walls immediately, above the extensions 15. Y

The inward ext'ensions 15 are not extended the full length-of the journal box,- but are terminated at their forwardends a short distance from the front end of the journal box.

WVhen the lubricant cellar isin normal position within the. side Walls of the ournal box,

its shoulders 13 rest upon the seats 16 of the box. Lugs 18 are provided on the sides of the lubricant cellar and normally. :extend intothedepressions 17, thereby holding the cellar, at the rear, against verticalmovement relative. to. the walls of-thejournal box, when the cellar'isfin its said normal position,..so that the edge '98; of the wall 9, is prevented from striking againstthe surface of theaxle 1 journal. p z I Depending lugs 19are provided. attheforward ends: of the sides 1410f. the journal box and a pin 20 is passed through said lugs. A i pair'of clamps 21 areheld by the pin 20. Each of the cl'amps comprises a handle 22,

'having an outwardly extending lug 23, in-

tegrally formed on'its rear end. Abolt 24 is formedon'the rear end of the bolt; A nut 00 wardly extending annular flange 27 a at its forward end and thespring 28 bears against the inner sideof'said flange 27a, its oppos1te end bearing against the head of the bolt.

The rear end of the housing 27 is internally threaded and a seat 29 is externally threaded and is screwed into the housing. An eye 30 is formed on the seat 29, and the pin 20 is passed through said eye, thereby supporting the clamp. At the opposite sides of'the clamps 21, on the pin 20, ferrules 31 are disposed, so as to space the clamps and hold them in proper positions on the pin. The front end of the bottom '11 of the lubricant cellar is projected outwardly at 32, beyond the wall 10, and the lugs 23 on the handles 22 are provided withdepressions 33 which engage the ex tended end 32 when the cellar is in normal closed position, holding the same against longitudinal movement, the springs 28, of the clamps 21, providingresiliency for drawingtheclamps rearwardly. A downwardly projecting lug 34 is formed on the bottom of the lubricant cellar at its forward end, and a downwardly projecting lug 35 is formed on the bottom of the lubricant cellar at its rear "end. When the cellar is in normal closed position, the middle ferrule 31' acts as a stop against which the lug 34 bears, thus limiting "the rearward movement of thecellar. When 37 is formed centrallyon the outer, face of 'the'c ellar and provides a gripping medium therefor; i

In the'operation of the device when it'is desired to remove or insert packing or lubricant in the cellar, the handles 22 of the clamps v '21'are pulled away from the end 32, of'the bottom'of the cellar, and the clamps 21 are p'ivotally swung'downward to the position shown in Fig. 5. The lubricant cellar is then withdrawn from the journal box by the lug ferrule 31., The shoulders 1.3 having overrun the seats 16, the cellar when in this extreme forward position is supported by the' middle ferrule 31, and it'isj then pivotally swung to the inclinedposition, shown in Fig. 5, the lugs 18 striking against thestops and thus limiting the further pivotal movement of the cellar. It will be obvious that when the packing and lubricant have been replaced in the cellar the latter may be readily restored to its normal closed position, by forcing the same upwardly and rearwardly and applying the clamps, as shown in Figs. 1 to 4 to hold the same securely in said closed position.

It will be apparent from the foregoing description that the present invention provides a journal box embodying a lubricant cellar which is readily installable in and removable from the box as a unit and which is adjustable to a position affording access to its interior to permit the replacement of packing and lubricant without the detachment of the cellar from the journal box. It will also-be apparent that the apparatus hereinbefore described is characterized by simplicity, sturdiness and durability, and is likewise relatively inexpensive to manufacture. Y 7

While there has been hereinbefore described a preferred embodiment of "the instant invention it will be understoodth at many and various changes and modifications in form and structure maybe made without departing from the spirit of the instantinvention and that all and any such changes and modifications as fall fairly within. the scope of the appended claims are contemplated as a part of thisinvention.
