DAll/ZPER Application filerlNovemoer 11, 1908.

[0 all whom it may concern:

Be it known that I, v' a iLLARD 0. WHITE, a citizen of the United States, residing at tepublic, in the county of Fayette and State of Pennsylvania, have invented a new and useful Damper, of which the followingis a specification.

This invention relates more particularly to a device for regulating the flow of heat in lines constructed for the utilization of waste heat from coke ovens to fire boilers, and the object of the present invention is to provide a damper embodying certain novel structural details, whereby the heat can be better and .101@ readily controlled.

in using the waste heat from coke ovens, the oven is connected to a main conduit or flue by a small flue, and from the main conduit lines are carried beneath the boilers in such a manner as to allow the heat to pass up back of the bridge-wall to the boiler tubes. Since the heat in the main conduit is variable, both in quantity and intensity, it is essential to the successful and safe operation of a boiler plant, that means be provided for shutting off from any boilers either all the heat, or a portion thereof, whenever desired.

In the accompanying drawings z Figure 1 is a central longitudinal section of the main conduit above referred to, showing the application of the invention. Fig. 2 is a transverse section on the line 2-2 of Fig. 1. Fig. 3 is a plan view. nig. 4 is a pers ective view of one of the slabs hereinafter refbrred to.

Referring more particularly to the drawings, 5 denotes the main conduit. Into this is built a pier or piers 6, whereby the line is divided into sections, each section to be of such width that a tile of ordinary size will span it, and lap sufliciently on the pier, and in grooves 7, formed in the opposite side walls of the flue. The top of the pier is spaced a short distance from the crown of the conduit. The bearing face of the pier and that of the grooves stand in the same plane, said plane being inclined from the vertical (toward the raft) sufiioiently to allow each tile to stay in position by its own weight. The tiles herein referred to are designated by the reference numeral 8. The grooves 7 are carried across the floor of the conduit, as indicated at 9, to prevent leakage under the tiles, the lowermost tile seating in said groove. The width of the grooves is such that the tiles will not bind therein. In the crown of the con- Specification of Letters Patent.

Serial No. 462,186.

duit is an opening 10 of such a length that the tiles may be placed. in position on the inclined face of the pier 6, the end of the opening being in line with the inner walls of the grooves 7. The width of the opening 10 is such that a tile of ordinary size can be used for a cover. Such a tile is shown at 11.

To operate the damper, the cover 11 is removed, and the desired number of tiles lowered to position by means of tongs. When it is desired to shut the heat off entirely, a sufiicient number of tiles will be lowered to completely close up the conduit, and the cover 11 can be left off, after the tiles are in place, whereby the opening 10 will permit a counter-draft of cool air to pass in and act as a check on that portion of the conduit ahead of the damper. It will be seen from Fig. 2, that the tiles extend en tirely across the conduit, so that, by placing more or less of such tiles in position on the pier 6, the heat is readily controlled. The grooves 7 are inclined at the same angle as the face of the pier, and these grooves, together with the groove 9, securely hold the tiles in place, each tile being held in position by its own weight.

The damper structure herein described can be easily and cheaply built, and it effectually serves the purpose for which it is designed.

The brickwork 12 surrounding the opening 10, has its top course lined by a frame of angle or T-irons 13, to prevent dislodgment of such course, and losing thereof during the manipulation of the tiles.

The number of piers employed will depend on the width of the flue.

What is claimed is 1. The combination with a conduit, of a pier therein, and a series of slabs supported on one face of the pier, and extending across the conduit.

2. The combination with a conduit, of a pier therein, having an inclined face, and a series of slabs supported on said face, and eX- tending across the conduit. I

3. The combination with a conduit having a groove in opposite walls thereof, of a pier in the conduit, having an inclined face which is in alinement with the aforesaid grooves, and a series of slabs supported on said inclined face, and extending across the conduit into the aforesaid grooves.

4. The combination with a conduit having a groove in opposite Walls, and an opening in the adjoining Wall communicating with said grooves, of a pier in the conduit having an inclined face in alinement With the aforesaid grooves, and a series of slabs supported on said inclined face, and extending across the conduit into the grooves.

5. The combination. with a conduit having a groove extending across the floor thereof, a pier in the conduit having an inclined face I i l l 1 extending to said groove, and a series of slabs supported on said inclined face, the loWerf inost slab seating in the groove.

6. The combination with a conduit, of a pier therein, and a series of slabs removably across the sections said slabs being remov- 20 able successively to increase the area of the conduit sections.

In testimony that I claim the foregoing as my own, I have hereto ailixed my signature in the presence of two Witnesses.

WILLARD O. i VHITE.
