UNITED STATES PATENT OFFICE.

THOMAS J. HICKEY, OF RONDOUT, NEW YORK.

SPECIFICATION forming part of Letters Patent No. 260,683, dated July 4, 1882.

v Application tiled December 19, 1881. (No model.)

To ,all whom it may concern Be it known that I, THOMAS J. HICKEY, a citizen of thel UnitedStates, residing at Rondout, in the county of Ulster and State of New York, have invented certain new and Vuseful Improvements in Ventilating Devices, of which the following is a specification, reference being had therein to the accompanying drawing. Y

My invention relates t0 a new and improved article of manufacture in ventilatiug devices; and it consists in the construction and arrangement of its several parts, as will be hereinafter fully'set forth, and pointed'out in the claim. l

In the drawing is shown a side elevation ot' a stove and pipe'with myimproved ventilator attached thereto, and in which A is the stove, and B the pipe. It is Ilot necessary that I-ither the stove or pipe be of special design in order to accommodate my ventilator, but

may be of the various kinds houses.

In order to facilitate the description of. the invention, I have lettered the upper portion of the stove-pipe b2 and the lower portion b', and have applied the letters b, C, c, D, and d to the different parts of the device'.

My ventilator consists of a straight sleeve, b, of slightly larger diameter than the stovepipe, to the curvature of which it conforms, and into the ends of which the sections b b2 are telescoped, as shown in the drawing. The sleeve b then -becomes firmly united to and a part of the stove-pipe, and the smoke and gases have free access or passage through it. The sleeve differs in no respect from the stovepipe, except that it is of slightlylarger diameter and is much shorter than an ordinary pipesection. y

Projecting horizontally from the side of the sleeve through a suitable aperture is the pipe G. The portion ot' the pipewithin the sleeve is curved upwardly, asy shown in dotted lines in the drawing, and extends a short distance generally used in above its upper edge in order to increase the draft through the pipe and to prevent the draft b from becoming displaced by the weight of 6o the pipe U and nozzle D.

The operation of the ventilator will be readily understood by inspection ot' the drawing.

Among its advantages over. the various kinds of ventilators in use are enumerated simplicity of construction and economy of manufacture, perfection of operation, and adaptabil ity to all kinds of stoves.

What I claim is-S A new and improved article in manufacture in ventilators, consisting of a straight sleeve, b, of slightly larger diameter than the stovepipe, and adapted to receive into its ends the sections of said stove-pipe, of a pipe, C, secured through said sleeve, the portion within being curved upwardly and projecting slightly above its top, the outer portion extending horizontally to a point over the center ot' the stove, bent downwardly, and provided with adamper, c', and having a nozzle, D, attached to its lower end, said nozzle having a brace, d, secured to its rim and attached to the stove-pipe, all arranged and combined to operate as set forth.

In testimony whereofI affix my signature in presence of two witnesses. v

THOMAS J. HIGKEY.
