DUMPING-BOTTOM FOR ASH-FANS 0F LOCOMOTIVES.

Specification of Letters Patent.

Application filed July 5, 1911.

Patented Dec. 19, 1911.

Serial No. 637,037.

To all whom it may concern:

Be it known that I, OSCAR GOLDEN, a citizen of the United States, residing at El Paso, in the county of El Paso and State of Texas, have invented certain new and useful Improvements in Dumping-Bottoms for Ash-Pans of Locomotives, of which the following is a specification.

The object of my invention is to provide a bottom for the ash pan of a locomotive boiler furnace whereby the ashes. may be quickly dumped, so that the engineer will not have to lose the time in stopping for thefireman to get down and rake out his ash pan.

It relates to that class of dumping ash pan bottoms having conjoined floor sections, each made to rock about its longitudinal axis and all connected to rock together to open or close the bottom at will.

My invention consists in the novel combination and arrangement of mechanism for connecting a fluid pressure cylinder to the rocking floor sections for operating them; in novel means for connecting the rocking sections with end doors on a level with the bottom, whereby all are opened and closed together, and also in other details of construction which will be more fully described hereafter with reference to the drawing, in which:

Figure 1 is a vertical longitudinal sectional view of the rear end of a locomotive furnace with my invention shown applied thereto partly in side view and partly in vertical longitudinal section. Fig. 2 is a sectional rear end view taken transversely through the cab. Fig. 3 is a plan view on a larger scale of my ash pan, and Fig. 4 is a side view of the ash pan taken from the opposite side to that shown in Fig. 1.

In the drawing, Figs. 1 and 2, X represents the furnace fire box, Y its grate bars and Z the cab.

A represents the side walls of the ash pan which correspond to the side walls of the furnace below the grate.

On a level with the bottom of the ash pan are the conjoined floor sections consisting of a series of transverse dump bars B, the edges of each of which join on to the edges of the adjacent ones with a rabbeted joint to make a continuous floor for the bottom of the ash pan to hold the ashes. Each of these dump bars has on its upper side a longitudinal shaft D along its middle line which is rigidly fastened to each bar and has its ends extended through bearings in the side walls of the ash pan so that the dump bars may rock with said shafts. At one end the shafts are each provided with a rigidly attached crank arm. C, Fig. 1, which extends upwardly outside of the side wall of the ash pan and all of these crank arms are arranged parallel and at their upper ends are jointed to or pivotally connected to a long horizontal bar E which runs parallel along the side of the ash pan just outside the same. This bar E is slotted down its middle, or made in two pieces connected at the ends, so as to leave space for the upper ends of the crank arms O to extend through the same. At its end next to the furnace door this bar E is jointed to the outer end of a horizontal crank arm F, Fig. 3, rigidly fixed to and projecting from a vertical rock shaft G turning in bearings in brackets H H projecting from the face of the ash pan below the furnace door. On the same faceof the ash pan, which is the rear face as regards the travel of the locomotive, there is secured by suit-able yokes and bolts a horizontal steam cylinder I. This cylinder is arranged in horizontal position below the cab floor and has within it a steam piston J and a piston rod K which extends through one head of the cylinder and is forked and secured by a loose pivotal pin to the end of a small crank arm L rigidly fixed to the vertical rock shaft G at right angles to crank arm F. Around the piston rod and between the piston and its head next to the upright rock shaft is a coil spring M. On the other side of the piston there is tapped into the cylinder a steam pipe N having a conveniently placed valve 0 by which steam may be admitted to the cylinder to cause the piston to compress the spring M and rock the vertical rock shaft G. The steam pipe N is extended under the floor of the engine cab and comes up on the left hand side of the boiler inside of the cab, where the valve 1) is placed and may be connected to the blower for the engine or to any other steam connection with the boiler to furnish steam to operate the dumping cylinder.

signed to be opened and closed with the dumping bars B and for this purpose the shaft of the middle one of the dump bars is extended through the side wall of the ash pan and has rigidly attached to its end a double crank lever P, one crank of which is connected by a bar Q to an offset R from one end door 0, and the other crank of which lever is connected by another bar Q? to an offset R from the other end door, so that as the dump bars are rocked to open and close them, the same movement through the double crank lever P and bars Q, Q also opens or closes the end doors O 0 the end doors being opened by the same movement that opens the dump bars for dumping the ashes, as seen in Fig. 4.

At the ends of each dump bar B next to the sides of the ash pan there are cross pieces Z) between the dump bar B and its shaft D. These pieces close the joint at the ends of the dump bars next to the side walls of the ash pan, reinforce the ends of the dump bars, take up wear, and also cause the shafts of the dump bars to be offset from the bars so that ashes do not hang against the same. This shaft is connected to the dump bar through the cross pieces at the ends.

The operation of my invention is as follows: The floor sections of the ash pan are ordinarily closed, as in Figs. 1 and 3. WVhen, however, the ash pan gets full of ashes and the engine begins losing steam, the valve 41 is opened and steam is admitted to the cylinder I to rock the vertical rock shaft G and, through the long crank arm F, horizontal connecting bar E, and parallel crank arms C, opens all of the floor sections by turning the dump bars on their axial centers, as in Fig. 4:, thus discharging the ashes and simultaneously opening the end doors without stopping the engine or requiring the fireman to get down and rake out the ash pit, thus saving much valuable time and labor. By opening the end doors, a draft of air over the opened floor sections cleans out all adhering ashes, and with such doors and dump bars open the draft of the fire above the grate is greatly stimulated. When the doors and dump bars have been opened long enough, steam is cut off at the valve o and then the spring M in the cylinder brings back the parts to their normally closed position. To aid in this action a supplemental spring S, Fig. 1, may be placed on the side of the ash pan, one end attached to the horizontal bar E and the other end to the side of the ash pan.

In order to allow the steam to escape from the cylinder any of the well known means.

may be employed, such as a three way valve at c or an ordinary plain discharge cock in pipe N below the cab floor.

To dump the ash pan by hand, if desired, the upper end a of the vertical rock shaft G is extended above the cab floor and is.

squared to receive the square socket of a detachable operating handle. The vertical rock shaft Gr with its two cranks F and L connects the horizontal piston rod of the cylinder at the rear of the ash pan, and below the cab floor, to the side bar E and crank arms C of the dump bars since crank arm F projects to the side of the ash pan. This not only places the cylinder out of the way below the cab floor at the rear of the furnace, but connects the piston of the cylinder around the corner to the crank arms C of the rocking floor sections whose axes are transverse to the line of travel and it also allows the straight upward extension of the rock shaft G through the cab floor, to allow it to be manually operated when desired, thus making a very compact arrangement of operating devices without encroaching upon the space within the cab. It will also be seen that the horizontal crank connections L and F are not only below the cab floor but are above the bottom of the ash pan where the parts are not likely to be struck by obstructions in the road bed.

I claim- 1. An ash pan for locomotives, comprising a floor composed of rocking conjoined sections arranged on axes transverse to the line of travel and means for simultaneously rocking them consisting of a cylinder with piston and rod arranged horizontally beneath the cab floor in rear of the ash pan transversely to the line of travel, and mecha nism connecting the piston rod of the cylinder to all of the rocking floor sections consisting of a vertical rock shaft at the rear of the ash. pan having its upper end extending above the cab floor and fashioned for manual operation and having two cranks below the cab floor and above the bottom of the ash pan and arranged at an angle to each other to oscillate in a horizontal plane, one of which cranks is connected to the piston rod and the other of which projects to the side of the ash pan, a side bar connecting with the latter crank and arranged at the side of the ash pan parallel to the line of travel and rigid crank arms for each rocking floor section loosely connected to the side bar.

2. An ash pan for locomotives having a floor composed of rocking conjoined sections arranged transversely to the line of travel and means for rocking them consisting of a cylinder with piston and rod arranged horizontally below the cab floor in rear of the ash pan and transversely to the line oftravel, a vertical rock shaft having two cranks arranged horizontally below the cab floor and above the bottom of the ash pan, one of which is connected to the piston rod, and the other of which extends to the side of the ash pan, 3, side bar connected to the latter crank and means connecting the side bar to the rocking floor sections, the middle one of said rocking sections having its end opposite the rocking mechanism extending outside the ash pan and provided with a rigidly attached double crank lever arranged outside the ash pan, two pivoted end .doors for the ash pan and two connecting rods connecting the end doors to the opposite ends of the double crank lever for simultaneous operation of the floor sections and end doors.

3. In an ash pan having rocking floor sections, the combination with the floor sections of cross pieces at the ends thereof adjoining the sides of the ash pan to take up wear and make a tight fit, and shafts extending ,the full length of the floor sections, attached to the floor sections through said cross pieces and having at the ends a series of rocking devices all connected for simultaneous operation.

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

OSCAR GOLDEN.
