SPECIFICATION forming part of Letters Patent No. 723,620, dated March 24, 1903. pplication filed May 28 1902. Serial No. 108,678. (No model.)

To all whom it may concern: v

Be it known thatl, JOHN PECK, acitizenof the United States, and a resident ofrHaverstraw, in the county of Rockland and State of New York, have inventeda new and Improved Brick-Kiln, of which the following is a full, clear, and exact description.

The object of this invention is to construct a brick-kiln in which the draft through the arches will be more effective than in the usual construction, thus enabling fuel such as oil and soft coal to be used advantageously.

This specification is an exact description of one example of my invention,while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification; in which similar characters ofreference indicate corresponding parts in all the views Figure 1 is a view showing partof the-kiln in front elevation and illustratinganother part broken away to show the interior con-g struction of the arch. Fig. 2 is .a vertical section on the line 2 2 of Fig. 1, and Fig. 3is a horizontal section on theline 3 3 of Fig.1.

e indicates the arch, which may be of the usual form and which hasat eachend a stoking door-openinge,extendingfrom theground or bottom of the-arch upward.

The invention consists in locating in the middle of the arch e,intermediate, theend grate-bars a, a sort of grate built up of "brick arranged in checker-work, and according to the construction here shown consisting of a supporting-pier b, on which are laid the top bricks c, the said top bricks being placed transversely and being spaced fromeachother, so as to allow-the draft to pass freely. between them. The grate-bars a are of metal and'of the, usual construction andextend from the checker-work to and into the door openings e. These bars, together with the checker-work formed of the bricks c and b, fill the entire length of the arch.

In burning, the kiln fire is started on the grate-bars a, the firemen stoking simultaneously through. the openings e and the fires at the ends of the arch gradually worked inward toward the center until the two fires meet, and the whole arch will then be under the action of the fire. The advantage of this arrangement is that the bricks Z) and 0 form practically a grate, and the 'fire' may be burned thereon as effectively'ason the iron bars a, while at the same time the expense of maintainingthe ironbars is avoided, for if iron grate-bars be extended entirelythrough 'the arch they will soon be burned away at the middle portion of the arch, which is too far from the mouths to be cleaned, because it is extremely difficult, if not impossible, for a workman to rake out the ashes from the middle of the arch or slice the. fire, and the ashes accumulating under and on top of the iron grate at the middle of the arch will cause the bars to be burned away. The brick employed to make the grate in the middle of the arch are, however, indestructible. building the kiln to fornrthis checker-work in the middle-0f the arch I employpreviously-burned brick, since green brick have not the strength necessary for thispurpose. By constructing the kiln in this mannerIam enabled to maintain a fire throughout the length of the arch, and I avoid the necessity of frequently changing the grate-bars.

Having thus described my invention, I

vclaincras new and desire to secure by Letters Patent-I r 1.. A brick-kiln having a grate at each end of the arch and havingin thefmiddle portion of the arch an open or checker work of brick to which the grate-bars extend, for the purpose specified, said brickwork'being formed of-ra pier running longitudinallyalong the arch, and of top Ibricks placed transversely on the pier and extending horizontally from each other "to thewalls of the arch, said top brick being spaced from each other to admit a circulation of air between them.

checker-Work of brick, outward to and into name to this specification in the presence of said door-openings at the ends of the arch two subscribing witnesses. and at an elevation below the tops of said openings,wherebyto permit continuous firing JOHN PECK 5 through each door-opening equally upon each Witnesses:

of said iron grates. J. HEFFERNAN,

In testimony whereof I have signed my ISAAC B. OWENS.
