IMPROVEMENT IN COAL-HODS.

Specification forming part of Letters Patent No. 410,061, dated September 22, 1863.

To all whom t may concern:

Be it known that I, JEssE PILBEAM, of Seneca Falls, in the county of Seneca and State of New York, have invented a new and useful Improvement in the Construction of Coal-Hods; and I do hereby declare that the following is a full and exact description thereo, reference being had to the accompanying drawings, making part of this specification.

Figure 1 is a central vertical section of a coal-hod provided with my improvement; Fig. 2, a perspective view of the removable bottom; Fig.3, a perspective view of the bottom portion of the receptacle; Fig. 4, a similar view of the top 0f the base; Figs. 5 and 6, perspective views of the ring which connects the recep tacle and base Fig. 7, a view of a rim used in connection with the ring shown in Fig. 6.

Like letters of reference indicate correspond ing parts in all the figures.

In the ordinary mode of constructing coalhods the whole device is made of sheet-iron. The wear and strain, which is considerable, on account of the weight of the coal, comes on the bottom and sides of the receptacle. The effect is to quickly Wear or break out the bottom, and also to spread out or expand the sides near the bottom, that being the narrow est point, on account of the conical shape of the hod. When either of these results occur, the whole device is worthless. To partially remedy this diticulty, ahod has been employed in which the upper part or receptacle is made of sheet-iron in the usual way, but the whole base is made of cast-iron. This obviates the breaking or Wearing out of the bottom, but does not remedy the expanding of the sides of the receptacle, and has, besides, been found so costly, and, above all, so heavy as to be of not much value.

It is the object of my invention to obviate these diiiculties by the production of a coalhod in which both the receptacle and base are made of sheet-iron, but separate and independent, instead of one piece, and connected by a stiff intermediate ring, that serves the double purpose of bracing the sides of the receptacle against outward pressure and for the attachment and support of a removable bottom, which, when worn, may be taken oli" and another substituted in its place.

As represented in the drawings, the hod is When the two parts are in place, these ilanges are coincident, resting one on the other, as shown in Fig. 1.

The receptacle and base are rmly connected together by means of a ring, C, Figs. 5 and 6, which is preferably, though not necessarily, made of cast-iron. It is provided with a narrow bed 0r ange, d, projecting inward a suitable distance, on which the ianges a b of the receptacle and base rest when in place, and a vertical rim or shoulder, f, of suitable height to form a sortof dash to receive the end of the receptacle. Over the opening of this ring fits the removable bottom D, Figs. 1 and 2, which is a plain disk, whose edges rest on the iiange a of the receptacle when all are fitted together, as in Fig. l. The parts are all secured by means of a screw or screws, h, which may either pass down through a central bearing, g, of the ring, as shown in Fig. 5, or through several bearings or flanges, g g g, near the periphery, as in Fig. 6. In the latter case, as the great strain comes in the center, I prefer to use a thin rim, E, on top of the removable bottom, provided with iianges g g' g', coincident with those of the ring beneath. The use of this gives a greater stiffness to the bottom, and renders it stronger than if the screws held only on said bottom. There are other manifest means of securing the parts together which may be employed. When the parts are all thus secured, it will be seen that the two flanges a. b of the receptacle and base are irmly clamped between the removable bottom and the bed-ange d of the ring, being thus rigidly held together.

rIhe advantages of this arrangement are manifest. The parts are easily put together or taken apart, and if any one of them becomes worn out or useless it is easily replaced without the destruction of the Whole device. The removablebottorn is subject to the greatest Wear and strain, but being merely a plain disk, can be replaced with but slight cost.

The lower end of the receptacle, by fitting Within the shoulder f of the ring, cannot expand or spread outward, as said shoulder forms a perfect brace against any such action, ard always retains it in place. I secure these advantages Without the addition of any material extra Weight to the device, the ring being very light, .while I retain all the benefits attained by the use of a cast-iron base, with many others not possessed by that. The cost of manufacture, in the aggregate, is as small
