SPECIFICATION forming part of Letters Patent No. 589,610, dated September 7, 1897.

Application filed February 12, 1 897.V Serial No. 623,145. (No model.)

To all whom t indy concern:

Be it known that I, ROBERT MCPHAILL, a citizen of the United States, residing at Brenham, in the county of Td/ashington and State of Texas, have invented a new and useful Stovepipe, of which the following is a speci iication.

The invention relates to improvements in stovepipes.

The object of the present invention is to provide a stovepipe adapted for cooking and hea-ting stoves and capable of deilecting the sparks and of causing' the same and soot to drop back into a stove and thereby avoid any liability of setting a house on fire or injuring the sections of stovepipe between it and a chimney.

A further object of the invention is to provide a stovepipe which will confine the heat tc the stove and prevent the same from passing up the chimney or iiue and at the same time not interfere with the draft.

The invention consists in the construction and novel combination of parts, as hereinafter iulliT described, illustrated in the drawings, and pointed ont in Athe claims hereto ap pended.

In the ,drawingsJ Figure l is an elevation of a stovepipe 'constructed in accordance with this invention. Fig, 2 is a longitudinal sectional View, the damper` being closed in full lines and shown open in dotted lines. Fig. 3 is a horizontal sectional View on line 3 3.0i

Fig. Fig. is a similar view on line et of Fig. 2. Fig. 5 is a detail perspective view of the damper.

Lilie numerals of reference designate correspondin g parts in all the figures of the drawings.

l designates a stovepipe-section provided with a central enlarged portion or chamber El, which is cylindrical between its ends, and the latter taper toward the end portions 3 and e of the stovepipe-section. The end portions 3 and 4 are ot' the ordinary size, the upper end portion 3 being adapted to iit into another stovepipesection and the lower end portion 4 being designed to it upon a stove in the ordinary manner.

1Within the chamber 2 of the stcvepip'e-sec tion is arranged an upper inclined deflector, a damper 5, and a lower inclined deflector G, which is substantiallysemicircular and which extends across one-half of the chamber 2. The detlector 6 is secured at its curved edge or periphery to the interior of the stovepipesection, and it is provided with a curved slit,

'forming a segmental bod)7 portion and arranged parallel with the curved edge of the deflector. The segmental bodT portion 7 of the inclined deflector is depressed slightly and is arranged in a plane below the curved edge or peripheral portion and forms an opening whereb7 it is adapted to have sparks impinge against it `and be dei'lected downward and at the saine time permit a snfiicient draft at that side of the chamber The upper dellector 8 is constructed similar to the lower deiiector (5, and the damper 5, which is hinged to the upper rigid deiiector S, is similarlyT constructed. The upper `deilect'or'Sis located above the lower deflector G at the opposite side of the stove-pipesection, and the damper 5 is located directl57 over the bottom deliector, wherebjVT a tortuous passage is provided for the smoke and other products of combustion, the lower deileetor being adapted to stop the sparks at one side of the chamber and the upper deflector at the other side of the saine.

The damper and the upper delector converge downwardly and are provided near their curvededges with slits and have segmental body portions which are depressed below the planes of the peripheral edge porf tions.

The damper 5 is mounted on a shaft or rod l0, which is extended through the sides of the chamber 2 and provided with an exterior han die 1l. A coiled spring l2 is disposed on the rod or shaft between the handle and the stovepipe-section and friction allyT engages the parts sufficiently to maintain the damper at the desired adjustment.

The openings in the deliectors and damper permit a limited draft when the damper is closed, and the diameter of the enlarged portion er chamber 2 of the ,stovepipe-section is sufficient to provide for all'the draft desired when the damper is open.

IOO

It will be' seen that the stovepipe-section is adapted to confine the heat in a stove and prevent it from passing out through the ohin1- ney or iiue, that it serves as a spark-arrester, and that it will eause the soot to drop back into the stove. It will also be apparent that it will protect the other sections of a stovepipe and Will prevent a house catching on iire by reason of flames or sparks passing into a chimney or flue.

1. The'eombination with a stovepipe-section, of an inclined segmental defleotor arranged therein and provided near its upper edge with an opening, and a damper hinged to the deflector and inelining upward in the opposite direction, substantially as described.

2. A stovepipe-section provided with an inclined defieetor arranged at one side thereof, and provided near its upper edge with a slit scribed.

In testimony that I'olaim the foregoing as my own I have hereto affixed my si gnature in the presence of two Witnesses.

ROBT. MCPI'IAILL.
