EDWARD GURNEY, OF TORONTO, ONTARIO, CANADA.

SECTIONAL BOILER.

SPECIFICATION forming part of Letters Patent No. 389,460, dated September 11, 1888.

Serial No. 274,561. (No model.)

To all whom it may concern,.-k

Be it known that I, EDWARD GURNEY, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, manufacturer, have invented a certain new and useful Improvement in Sectional Hot-Vater Boilers, of which the following is a specification.

The invention relates to that class of boilers constructed ofa series of horizontal sections,

each section being hollow to contain Water,

and all rthe sections connected together by water-legs, so that the water shall flow freely from one section to the' other, spaces being left between the sections, through each of which vertical smoke-fines are formed, the combined area of which is sufficient for the fullrequirements of the boiler.

,The object of the present invention is to arrange a simple damper by which the area of the center iiues in the top section may be reduced or completely stopped at will to retain the heat as long as possible in the lower sections; and it consists, essentially, of a diskshaped valve pivoted on the center of the top section, and having a series of holes made through it to correspond with the center smoke-iiues in the top section, which fines should be an equal distance apart, substantially as hereinafter more particularly eX- plained.

The drawing represents a perspective top view of a section of a boiler, showing the ap plication of my cut-oft` damper.

A represents a disk-shaped damper pivoted in the center of the section B.

C are a series of holes made in the damper A, the centers ot' which holes are made on a radius struck from the center and pivot-point of the damper.

D represents the center tlues in the section B. These fines correspond with the holes C, and their centers are on the same radius as the centers of the holes C.

Eis a handle permanently or detachably connected to the damper A, and extending outside of the section B.

" F and G are two stops projecting above the surface of the section B at such points that when the damper A is turned on its pivot so as to bring the handle E against the stop F the holes C register with the iiues D, thus leavingthem full open, and when the damper A is turned on its pivot, so as to bring the handle E against the stop G, the center tlues, D,`will be completely covered by the damper. In this way the center flues will be opened, so as to give the full draft of the boiler for kindling or other purposes, and when closed. to retain the heat as long as possible in the lower sections. Any desired condition of draft may be had by adjusting the damper at any desired point between the stopsF and G. By the adoption of this damper I am enabled to reduce the area .of the smoke-fines, thereby checking the draft and forcing the products of combustion to escape through the outer smoke-fines.

Vhat I claim as my invention'is l. In a sectional hot-water boiler, a section having a series of vertical smoke-lines made in its center, in combination with a diskshaped damper pivoted in the center of the section, and having holes pierced through it to correspond with the smoke fines in the section, the whole heilig arranged substantially as and for the purpose specified.

2. In a sectional hot-water boiler, a section having a series of vertical smokeiiues, D, made in its center, in combination with a diskshaped damper, A, pivoted in the center of thesectionand havingholes C pierced through it to correspond with the smoke-dues D in the section B, stops F and G, extending above the section B, and a handle, E, attached to t-he damper A and extending to the outside of the section B, substantially as and for the purpose specified.
