IMPROVEMENT IN COAL-SCiUTTLES.

Specification forming part of Letters Patent No. 162,367, dated April 20, 1875; application filed February 12, 1875.

To all whom it may concern:

Be it known that we, HENRY FELDMEIEP. and EDWARD STOEPPELWERTH, of St. Louis, St. Louis county, State of Missouri, have invented a certain Improvement in Goal-Sent tles, of which the following is a specification:

Our improvement consists in a screen which is inserted near the bottom to allow the coaldust to pass through. The chamber beneath the screen is continued up the spout side of the scuttle to receive the dust when the soot tle is tilted to discharge the coal. A vent is provided for the discharge of the dust, and this vent is ordinarily covered by a slide held in place by a set-screw.

In the drawings, Figure 1 is a perspective view of the scuttle having our improvement with part broken out to show the screen, and the sliding gate raised to show the dischargeaperture of the dust-chamber. Fig. 2 is a vertical longitudinal section. Fig. 3 is an enlarged horizontal section through the front part of the scuttle at a m, Fig. 2, the gate being closed. Fig. 4 is a top view of screen when formed of wirework, the walls of the scuttle being in section at w m, Fig. 2.

A is the body of the scuttle. B is a false bottom, made either of foraminated plate metal or wire fabric of the proper strength to sustain the coal, and the meshes sufficiently large to allow the dust to fall through. This screen B is tightly secured to the sides of the scuttle all around, except upon thefront side,where it is secured to a plate, 0, whose sides are secured to the sides of the scuttle by rivets, and whose top is attached to the spout by turning over the edges at c. The dust-chamber D extends between the plate or screen B and the bottom E, and beneath the plate 0 and spout or front side F of the scuttle. When the screen is made of wire-work it should be supported by cross bars G of hoop iron, whose end-s 9 turn up to form ears for rivet attachment. The screen, as shown in Figs. 1 and 2, has similar rivet-lugs g. H is a gate sliding in guides I, to close the aperture K for the escape of dust from the chamber D. In Fig. l the gate is shown raised and the aperture open, and in Fig. 2 the gate is shown down. L is a set-screw, which passes through the gate and through a slot, M, in the front side F, and screws into a plate, N, which is recessed to receive the two in-turned flanges at the edges of the slot M. The ends a n of the plate rest on against the inner side of F when the set-screw is turned forward, and hold the gate in place, as shown in Figs. 1 and 2.

\Ve claim as our invention- 1. In a coal-scuttle, the combination of a perforated false bottom, B, plate or partition U, and sliding gate H, as and for the purpose set forth.

2. The combination of the coal-scuttle A, false bottom B, partition or plate 0, chamber D, having discharge-aperture K, sliding gate H, and set-screw L, as and for the purpose set forth.
