LOCOMOTIVE ASH-PAN.

SPECIFICATION forming part of Letters Patent No. 326,731, dated September 22, 1885.

Application filed June 25, 1885.

To all whom it may concern;

Be it known that I, JAMES GRAHAM, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Locomotive Ash-Pan, of which the following is a specification.

My invention relates to improvements in locomotive ash-pans, by which the ashes may be dumped by the operator without leaving the cab of the locomotive by means of a lever operating a movable bottom. I attain this object by the mechanism illustrated in the accompanying drawings, in which Figure l is a perspective view of the ashpanwhen detached from its place under the grate, showing the device for working the bottom and its position when the bottom is closed, as seen from the front. Fig. 2 is a perspective view from the rear, showing the position of parts when the bottom is open. Fig. 3 shows a section of the bottom plates.

Similar letters refer to similar parts in all the views.

I construct my ash-pan with the longitudinal sides A A sufficiently oblique to leave the bottom of the pan about one-third the width of the top. The bottom is formed of two parts, B B, meeting when closed longitudinally along the line of the center, the contacting edges of which are beveled reversely, a, Fig. 3, so that they may partially lap when brought together, securing more perfect closeness. These parts of the bottom are adapted to slide each away from the center on the slideways I) I). These slideways may be formed of flanges turned inwardly from the bottom of the front and back end pieces of the pan, they being left rectangular in shape and of sufficient depth for that purpose. This leaves projecting parts 0 under the oblique sides of the pan, thus securing sufficient slideways for the bottom, and also bearings for the rotating rod D in said end pieces, F F.

To allow the bottom pieces, B B, to be at tached to the working device, they are formed with the extension or ear pieces 0 O at each end, which pieces project through the slots (2 d, cut in the front and rear end pieces of (No model.)

the pan, said ears having eye-holes in them-- the ones on the part B to allow the lower arms 6 c of the levers E E to work in them when sliding said part back and forth in operating the bottom, the ones on B to connect the same with the upper arms of the levers E E by the rodsff for a like purpose.

D is a rotating rod connecting the workinglever E with the rear lever, E, and rigidly fastened to each and resting on bearings in the projecting parts of the front and rear ends of the pan under the oblique sides.

Thepan may be provided with front and rear dampers, as shown in Fig. 1, g 9; but they are of little use, as the draft can be regulated through the adjustment of the bottom parts.

I am aware that different devices have been invented and patented for dumping the ashes of a locomotive ash-pan by means of a lever in the cab working a movable bottom; but all, as far as I am aware, are open to the objection of scattering the ashes and cinders across the track the whole width of the pan, to the great damage of rail and wheels.

.I avoid this, first, by the oblique construction of the sides of my pan, which forces the ashes to rest longitudinally along the center of the pan, and, secondly, by the manner in which the parts of the bottom open and slide away from said center, leaving the ashes deposited in a contracted line in the center of the track. Another ad vantage it possesses is,that it is not liable to be obstructed by cinders in working, which is very important when necessary to close tight in checking the draft, as no cinders can well rest on its closing edges, and if they did would be cut in pieces and pushed away. Besides this, the oblique sides act as scrapers in cleaning the bottom sections of all ashes and cinders when sliding back in (lumping.

\Vhat I claim, and desire to secure by Letters Patent, is

1. A locomotive ash-pan constructed with oblique longitudinal sides and rectangular vertical ends having slideways for the bottom, in combination with a sliding bottom longitudinally divided into two parts and the Working device for sliding the same, all subthe center and the working device for sliding stantially as described, and for the purpose the same, all substantially as described, and I0 specified. for-the purposes set forth.

2. A locomotive ash-pan constructed with 5 oblique longitudinal sides, reducing the bot- JAMES GRAHAM tom about one-half or less in Width than the Witnesses: top, in combination with a sliding bottom JAMES OBRIEN, longitudinally divided into two parts along WILLIAM S. SHEERAN.
