SPECIFICATION forming part or'l Letters Patent No. 778,677, dated December 2'?, 1904.

Application filed October 31, 1904. Serial No. 230,722.

To @ZZ wwnt it may concern:

Be it known that we, GEORGE W KING, HARRY J. BARNHART, and CHARLES B. KING, citizens of the United States, residing' at Marion, in the county of Marion and State of Ohio, have invented certain new and useful Improvements in Steam-Shovels or the Like, of which the following' is a specification, reference being had therein to the accompanying drawings. Y

This invention relates to steam-shovels and the like, and has for its object to provide for ample iiring-space when the shovel is at work, compactness during transportation, and adequate protection of the coal-box and tiringspace.

To these ends our invention comprises means whereby the coal -Ibox may be so connected to the car as to be swung out therefrom to give a maximum of tiring-space when the shovel is at work, said box being adapted to be swung' in within the normal boundaries of the car-body for the sake of compactness in transportation or when the shovel is not at work, the structure comprising in its preferred forni a hinged portion of the rear wall of the car-body, which portion forms a cover for the box when it is swung out and a closure for the opening in the end of the car-body when the box is swung in.

In the accompanying drawings, Figure I is a side elevation of so much of a steam-shovel embodying our invention in one form as is necessary to a comprehension thereof, the upper portion of the car being' in longitudinal section; and Fig. 2 is an enlarged view showing in detail the rear portion of the structure shown in Fig. I.

In'steam-shovels as now constructed, comprising a car and machinery and a boiler and furnace mounted thereon, the provision of ample space for the proper working of the structure without undue increase in the size of the car is of material importance.

It is the object of our present invention to provide a construction whereby ample liringspace is provided for the fireman or stoker Who supplies the boiler-furnace with fuel while the shovel is at work, arranging the fuel-supapparatus when ready for transportation is of the usual dimensions. It is also desirable to inclose and protect the parts during transportation and at the same time to protect the fuel and Iiring-space while the shovel is at work. These desirable ends we attain by the construction shown in the drawings, in whichl indicates the frame of the car, upon which the machinery of the shovel is mounted. This frame supports theV usual car-body 2, having an end wall 3, the lower portion of which (indicated at 4) is hinged at its upper edge, as indicated at 5, so as to swing' outward and upward, thus leaving an opening in the rear end wall of the car-body.

6 indicates the boiler, having the usual furnace 7, said'boiler and furnace being so located `on the rear portion of the car as to leave a tiring-space 8 between the rear firing or furnace end of the boiler and the rear extremity of the car. At said rear extremity of the car rthere is located a coal-box 9, preferably open `In this position of the parts the coal-box eX- tends rearward from the car, lying entirely beyond the end of the car, so as not to obstruct the tiring-space.v The coal-box may be supported in this its working position by means of chains 1l or any other suitable supporting means. Ve prefer to connect these chains, as shown, to the Lipper portion of the car-body at the sides thereof and to the rear lower portion of the coal-box at the sides of this latter. The working position of the coal-box is shown in full lines. Then the machine is not in use or when it is desired to prepare it for shipment or transportation, the coal-box may be tilted forward into the position shown in dotted lines, resting upon the deck or iioor of the firingspace and lying entirely Within the usual bounsgs daries of the car. When thus folded or tilted forward, it will be seen that the coal-box does not project beyond the car so as to interfere with theuse of the coupler 13 at the rear end of the car, and when swung out into working position, as shown in full lines, the coal-box does not obstruct or diminish the firing-space and is in a position where it may be readily filled with fuel and is at the same time conveniently accessible to the fireman.

It will be observed that when the coal-box is in working position the hinged portion 4L of the rear end wall of the car-body forms, in effect, acover for the coal-box in the form of an inclined roof which will protect the fuel therein, its free end resting on the rear upper edge of the box, so as to give free access to the fuel in the box from the front thereof. In this position of the parts the opening in the rear end wall of the car-body is in a large measure protected by said box and its cover. l/Vhen the box is tilted forward into shipping position, the cover or wall section 4L falls automatically into a vertical position, in which it may be secured in any suitable manner, closing the opening in the end wall of the car and inclosing and protecting the firespaee and coal-box during transportation.

Ve do not wish to be understood as limiting ourselves to the precise details of construction hereinbefore described and shown in the accompanying drawings, as it is obvious that various modifications may be made therein without departing from the principle of our invention.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. In a steam-shovel or the like, the combi nation, with a car having a boiler mounted thereon and provided with a firing-space between the boiler-furnace and the rear end of the car, of a coal-box pivoted at its forward edge to the rear end of the car so as to be swung' forward to rest on the car within the firing-space when not in use, said box extending rearward beyond the end of the car when in use, and means for supporting said box in this latter position, substantially as described.

2. In a steam-shovel or the like, the combination, with a car having a frame and body,

and a boiler mounted on said frame so as to have a firing-space between the boiler-furnace and the rear end of the car, of a coalbox pivoted at its forward end to the rear end of the frame so as to be swung forward to rest on the iiooring of the firing-space when not in use, said box extending rearward beyond the end of the car when in use, and means for supporting said box in this latter position, the end wall of the body having an opening through which the box may swing, a part 'of said end wall being hinged at its upper edge to the top of said opening, said part forming an inclined cover for the box, upon which it rests when the box is in working position, and assuming a vertical position to close the opening' in the endwall when the box is swung forward into nonworking position, substantially as described.

3. In a steam-shovel or the like, the combination, with a car having a firing-space, of a coal-box connected to said ear so as to be swung out therefrom to give a maximum of firing-space when the shovel is at work, said box being adapted to be swung' into the iii ing-space within the normal boundaries of the car for compactness in transportation, substantially as described.

4. In a steam-shovel or the like, the combination, with a car having a firing-space, of a coal-box connected to saidcar so as to be swung out therefrom to give a maximum of firing-space when the shovel is at work, said box being adapted to be swung into the {iring-space within the normal boundaries of the car for compactness in transportation, the car-body having an opening for the passage of the box and a portion of the wall of said body hinged to the upper margin of said opening' so as to rest on and form a cover for the box when it is swung out and a closure for the opening when the box is swung in, substantially as described.

In testimony whereof we aiix our signatures in presence of two witnesses.
