DEVICE FOR REMOVING OIL-CELLARS FROM 'THE DRIVING-AXLE BOXES OF LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 788,287, dated April 25, 1905.

Application filed December 1, 1902. Serial No. 133,376-

To all whom it may concern.-

Be it known that 1, PETER SwANsoN, of Soudan, St. Louis county, Minnesota, have invented certain new and useful Improvements in Devices for Removing Oil-Cellars from the Driving-Axle Boxes of Locomotives, of which the following is a specification.

The object of my invention is to provide compact, strong, and durable means for re moving oil-cellars; further, to provide a removing means that is equally adapted for use in the shops or on the road, is capable of easy and rapid adjustment to cellars of different size, and cannot slip out of place when in use.

The invention consists generally in various constructions and combinations, all as hereinafter described, and particularly pointed out in the claims.

1n the accompanying drawings,forming part of this specification, Figure 1 is a View, partially in section, of a portion of a locomotiveframe and cab, showing the position of one of the driving-axles and an oil-cellar applied thereto. Fig. 2 is a perspective of the driving-axle box, showing the oil-cellar and the removing device in position to withdraw the cellar from the box. Fig. 3 is a side elevation of the removing device. Fig. 1 is an edge view. Fig. 5-is a section of the oil-cellar.

1n the drawings, 2 represents a portion of a locomotive-frame; 3, the cab mounted thereon; 4:, a driving-axle; 5, one of the boxes therefor, and 6 a bearing-brass provided between the top of the axle and the box.

7 represents an oil-cellar that is arranged to [it into the box on the under side, as shown in Fig. 2, and provided with holes 8 to receive bolts (not shown) that pass through corresponding holes 9 in the box and hold the cellar firmly in place while in use. This cellar is of ordinary construction, having a receptacle for waste that is saturated with oil and in contact with the driving-axle. It frequently happens that this oil-cellar must be removed to renew the waste, repair or replace the cellar, and sometimes the removal operation must be performed (as in case of a hot box) when the locomotive is on the road, Where the usual conveniences of a yard or roundhouse cannot be utilized. At such times it has been found necessary to provide a hook device to be used in connection with a lever for drawing down the cellar out of the box, using some portion of the locomotive-frame as a fulcrum. This operation renders it necessary for the engineer to crawl in under the driving-axle, and as the necessity of removing the cellar frequently arises through heating of the box the cellar is often very difficult of removal and the whole operation becomes exceedingly tedious and laborious. To obviate all this delay and labor incident to the removal of an oil-cellar, I have provided a device consisting of arms 10 and 11, connected together at one end by a pivot 12, having outwardly-turned ends 13 at their ends opposite the pivot and provided with outwardly-curved middle portions intermediate to the ends. These outwardly-turned ends 13 are of proper size to enter the holes 8 in the cellar-box, and to prevent said ends from becoming disengaged from the box while the device is in use I provide a bolt 14, pivoted on the arm 10 and having a threaded end to enter a turnbuckle 15, in whose opposite end a threaded bolt 16 is provided. The bolts have oppositely-cut threads, and the bolt 16 has a head 17 provided with a beveled face 18, that is adapted to engage the ratchet-teeth 19 on the inner edge of the arm 11 and slide down over the same to separate and adjust the arms. By operating the turnbuckle 15 the device may be rigidly secured to the cellarbox and as easily disengaged therefrom. The arms can also be adjusted to cellar-boxes of different size and the device .adapted for use with any style or type of locomotive.

On the pivot 12 I prefer to provide a clevise 20, to which a chain 21 is connected and provided with a turnbuckle 22, and at the lower end of the chain I provide a link 23 to receive a bar 24, that slips under the rails. Upon operating the turnbuckle the chain will be tightened and the oil-cellardrawn out of the box. This chain and bar device is particularly useful when the locomotive is out on the road, where there is no pit Within which to handle a lever conveniently.

In operation the turnbuckle 15 is tilted with the threaded bolts to an inclined position to allow the arms to be drawn together and inserted within the recess in the base of the cellar. The ends 18 are then thrust into the holes 8, and the turnbuckle is drawn down to a horizontal position, the beveled face 18 of the head 17 sliding over the ratchet-teeth 19 until the arms have been fully separated to the limit of their spreading movement. The turnbuckle is then operated to force the head 17 against the ratchet-teeth and hold the ends of the arms firmly within the holes in the oilcellar. The head 17 is locked as it passes each tooth in its downward movement,and the arms cannot be again drawn together until the turnbuckle is loosened and the bolt 16 withdrawn sufliciently to allow the head 17 to become disengaged from the teeth, when the turnbuckle can be raised and the arms pressed together to withdraw their outwardly-turned ends from the holes in the cellar.

I claim as my invention 1. A device for removing oil-cellars from the driving-axle boxes of locomotives, comprising arms hinged together at one end and provided with outwardly turned opposite ends, a series of teeth provided on the inner edge of one of said arms, a bolt pivoted on the other arm, a second bolt having a beveled head to engage said teeth and a turnbuckle having right and left hand threaded connections with said bolts, substantially as described.

2. A device of the class described, comprising arms and 11 having aconnecting-pivot 12 and outwardly-turned ends 13 on the ends opposite said pivot, a series of ratchet-teeth 19 provided on said arm 11, a bolt 1A pivoted on the other arm, a bolt 16 having a head provided with a beveled face to engage said teeth, and a turnbuckle having a right and left hand thread connection with said bolts and provided between the same, substantially as described.

3. A device of the class described, comprising curved arms pivotally connected at one end and having outwardly-turned opposite ends, means for separating said arms and preventing their movement toward one another while in use, a chain connected with the pivoted ends of said arms, a turnbuckle provided in said chain and having right and left hand thread connections therewith, and means provided in said chain and adapted to engage a bar placed under the rails.

4. A device of the class described, c0mprising pivotally-connected arms having means to engage an oil-cellar, and means pivotally connected with one of said arms only and arranged to engage the other arm to force the arms apart and lock them, substantially as described.

5. A device of the class described, comprising pivotally-connected arms having means for engaging an oil-cellar, and an adjustable device pivotally supported on one arm and arranged to engage with a series of teeth provided on the other arm to force said arms apart and lock them, substantially as described.

6. A device of the class described, comprising pivotally-connected arms having means for engaging an oil-cellar, and a longitudinally-adjustable device pivotally supported on one arm only and arranged to engage the other arm.

In witness whereof I have hereunto set my hand this 21st day of November, 1902.

PETER SVVANSON. In presence of JNO. E. SMITH, JOHN H. JEFFREY.
