GRATE-FRONT.

EEPECIPICATION forming part of Letters Patent No. 310,437, dated January 6, 1885.

Application filed April 2, 1884.

To ctZZ whom it may concern.-

Be it known that I, EDWIN A. JACKSON, a citizen of the United States, residing at New York, in the county of New York and State of New York, haveinvented certain new and useful Improvements in Grate-Fronts; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to means for preventing polished, plated, or enameled grate frames or fronts from being discolored or tarnished by the action of heat.

It is well known that grate fronts or frames which are polished or plated with nickel or other metal very soon become discolored and lose their polish in the immediate vicinity of the grates, owing to becoming heated by the fire and by contact with the grates which they support, and in the case of enameled fronts the coating of enamel is brokenand peels off from the same cause.

In overcoming this disadvantage my invention consists in a rear flue-plate of novel construction, and the combination thereof with the upright side portions of a gratefront, as

hereinafter described, for the purpose of formin g air-fines. whereby are kept cool those portions of the grate-front which are otherwise liable to be tarnished or blistered by heat.

In the accompanying drawings, Figure 1 is a front view of a grate-frame provided with my improvement, the flue-plates being shown in dotted lines. Fig. 2 is a rear view of the frame. Fig. 3 is a perspective view of one of the flue-plates detached. Fig. l is a rear perspective View of a port-ion of one side of the grate-frame to which the flue-plate is secured.

In the present instance the uprights A A of the grate-frame have rearwardly-turned' flanges a at their edges, and the external surfaces are supposed to be highly polished and nickel-plated. On the rear surface of each upright is secured a flue-plate, B, which is held in position by a single screw; though a greater number of screws might be used if necessary, or any other suitable means offastenin g adopted. Each flue-plate has at one edge a trough like portion with walls 0 c joined at approximately right'angles, so that when the plate is (No model.)

placed against the rear surface of the upright A the outer flange and a portion of the front of the upright form the other inclosing-walls of a vertical flue, which is closed at its upper end and open at its lower end, a portion of the flange of the upright being cut away at the foot of the flue, as shown at (Z, to form an air-inlet.

From the upper portion of the wall 0 of the flue projects a plate, B, having upwardly-inclined upper and lower edges, and'recessed entirely across its width to form a shallow oblique flue. which intersects the vertical fine just described. A portion of the inner flange of the upright is cut away, as shown at f, in order to leave the mouth of this shallow flue open toward the grate.

From the inner edge of the plate B, near its upper edge projects a lug, g, for supporting the upper edge of the grate, which is to be engaged therewith in the usual manner, an- 7 other lug, g, or hook being cast on the rear surface of the upright for engaging properly with the fireplace lining or side wall. The upper lug, g, is shouldered, as shown at 7L, in order to prevent the grate from coming in con tact with the inner flange of the upright.

On referring to Figs. 1 and 2 it will be seen that between the upright and the fluc-plates are air passages or lines, which are open at their lower ends at the points (I d, and open at their upper ends directly into the opposite ends of the grate, and it will be obvious that when a fire is built in the grate a draft will be created which will cause currents of air to flow in the direction indicated by the arrows. The currents of air first ascend through the vertical fines, and, turning laterally, spread out into the shallow portions of the fines between the plates B and the uprights, so that broad currents of air continually flow in con tact with those portions of the uprights which are adjacent to the ends of the grate, and the polished fronts of which would be liable to discoloration by the heat were it not that these \Vhat I claim is 1. The combination, with the side uprights of the grate-frame, of the iiue-plates composed of the trough-like portions open at the bottom and the recessed portions extending laterally therefrom to the ends of the grate and open thereto, substantially as described.

2. The combination, with the side uprights having rearward]y-extending flanges which are notched opposite the position of the grate, of the flue-plates, each composed of a vertical trough-like portion closed at top and open at bottom, and the wide recessed portion 13, extending laterally from said troughlike portion to the notch in the adj aeent flange of the upright, said flue-plates being attached to the uprights respectively, and forming in conneetion therewith the inclosing-walls of air-fines which keep said uprights cool when fire is kindled in a grate supported between them, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
