GEORGE L. SMITH, OF BROOKLYN, NEW YORK.
GRATE.
Specification forming part of Letters Patent No. 57,396, dated August 21, 1865.
To all whom 'it may concern:
Be it known that I, GEORGE L. SMITH, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved FurnacevGrate; and I do hereby declare that the following is a full, clear, and exact descri p tion thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a perspective view of one of the oscillating bearers, showing three of the rectangular grates applied to it. Fig'. 2 is a section taken in a vertical plane through a series of grates, bearers, connectin g-rods, and levers, the upper surfaces of the grates being in a horizontal plane. Fig. 3 is a plan view of the grates and bearers with some of the gratesections removed. Fig. 4 is a sectional view, showing the grate sections in position for dumping the fire into the ash-pit.
Similar letters of reference indicate corresponding parts in the several gures.
The main object of this invention is to construct a grate for locomotive and other furnaces, which shall consist of a number of sections, each one of which is composed of a series of separated grate-plates that are applied to oscillating bearers and so constructed that the grates can, collectively or separately, be removed and reversed when the exposed surfaces become worn out, and new and unused surfaces presented to the fire, as will he hereinafter described.
Another object of my invention is to so construct a reversible sectional grate, in which each section is composed of a series of separated plates, that the bearers shall not be exposed to the injurious action of heat, at the same time to provide for allowing the several parts composing the grate to expand and contract freely without liability of straining or warping, as will be hereinafter described.
To enable others skilled in the art to Linderstand my invention, I will describe its construction and operation.
In the accompanying drawings, B B represent the two side bars, which are applied in any suitable manner within a furnace, and arranged so as to serve as supports for the grate. These side bars are notched or slotted to receive the ends of horizontal transverse bearers K K, which ends are rounded for the purpose of allowing these bearers to turn or rock freely iu their bearings.
Each bearer K receives upon ita number of triangular plates, the upper edges of which form the open grate-surface shown in Fig. 3. The form of these grate-plates c a is that of a ri ght-an gled triangle, which form presents two grate-surfaces, but exposes only one at a time, as shown in the drawings. Each one of these triangular plates a. has a square hole through it for receiving the bearer K, which, in crosssection, is of a similar form to said hole. 4Thus the plates may be applied loosely on their bearers and yet be caused to turn or oscillate with them.
The grate-plates a c and the lever-plates G G are constructed with flanges H H ou their sides, which serve two very important purposes,'viz: They serve as a means for spacing the plates on their bearers and keeping them at proper distances apart; and they also serve as guards or covers for protecting the bearers between the plates from the direct action of the iire.
By thus constructing the plates composing the gratesurface, and applying them to oscillating bearers, it will be seen that there are left free air-spaces between these plates and over the bearers for the passage of air to the iire.
The plates a a. and G G of each bearer will all be held securely in their places for shaking the coals and dumping them into the ash-pit, and the upper exposed edges of each line or series of plates will all be in the same plane, whether this plane be inclined, as shown in Fig. 4, or horizontal, as shown in Figs. 2 and 3.
Any number or all of the .plates can be removed from their bearers and others substituted in their stead at pleasure, and by removing these plates a a from their bearers when one exposed surface becomes burned out, and presenting the other perpendicular edge, a new grate-surface will be made. In this way a grate can be made to last for a long time. Some parts of the grate-surface are or may be more exposed to the rapid destruction of the re than other parts. Consequently, some of the plates a c may be very good while others may be entirely worthless, in which case it will be seen that, these destroyed plates can readily be removed from the bearers and reversed or others substituted in their stead.
The plates G G, which are placed at the ends of the bearers, are constructed with projections on their lower sides; Which form le- -vers or arms, to which the connecting-rod d d is pivoted, as shown in Figs. 2, 3, and 4. To
lthis rod d a link, F, is pivoted, by means of which a vibrating lever (Which I have not shown) can be employed for oscillating all the grate-sections simultaneously.
It will be seen, by reference to Figs. 2 and 4, that the bearers are arranged below the u`pper surfaces or edges of the grateplates and at equal distances from said surfaces and those which are at right angles to them. Consequently, the entire exposed surface of each section of the grate will receivea vibrating movement When the bearers are oscillated, which effectually breaks up the coke and clinkers and disturbs and agitates the Whole tire, so desirable in furnaces Where soft coal is used.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. A grate which is composed of a number of sections, each one of Which is made up of reversible plates so constructed that when one surface is burned out another surface can be presented, substantially as described.
