SPARK-ARRESTER.

SPECIFICATION formingpart of Letters Patent No. 228,922, dated June 15, 1880. Application led November 24, 1879.

To all 'whom t may concern:

Be it known that I, KARL FRIEDRICH WIL-A HELM NEUHAUS, of Halberstadt, Empire of Germany, have invented a new'and useful Ini-' provementin Spark-Arresters, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings, in which-- Figure l represents a vertical central section of my apparatus. Fig. 2 is a plan or top view of the same.

Similar letters indicate corresponding' parts.

My invention relates to spark-arresters for smoke-stacks or chimneys; and it consists in the combination of a smoke-pipe, a cap projecting below the upper edge of such pipe, a casing edge of the cap, an inclined tloor to the casing, and a conveyer extending from the lower part of such floor, so that any products of combustion issuing' from the smoke-pipe strike the cap, and, passing around the lower edge thereof, escape through the casing, in which circuitous course ot' such products the sparks or cinders held therein are deposited ou the inclined oor ot' the casing, whence they pass off through the conveyer. The cap has a pivotal support and carries a vane combined with a wi rid-guard partially surrounding the casing and projecting above its upper edge, so that the interior of the casing is sheltered from the wind and a uniform draft is insured.

In the drawings, the letter A designates the smoke-pipe; B, the cap; C, the casing; D, the inclined iioor of the casing, and E the conveyer.

The smoke-pipe A is connected to the upper end of a smoke-stack or chimney by means of a coupling, F, and the cap B is arranged at the upper end of the smoke-pipe in such a manner that it projects below the upper edge of the pipe. The support for the cap B consists of a central stem or pivot, f, and a socketpiece, g, which are tted to each other and respectively secured to the smoke-pipe and the cap. The casin g C is secured to the smokepipe A, and is made of such height as to project above the lower edge of the cap B. The inclined floor D of the casing is between the sameand the smoke-pipe A, so that it has an annular shape, and the conveyer E extends from the lowest part ot thistloor, the same being closed at the bottom by a sliding gate, h.

The products of combustion rising in the chimney issue from the smoke-pipe A and strike against the cap B, whence they pass down under the lower edge of -the cap and escape at the upper open end ofthe easing C. [n this circuitous course of the said products the sparks or cinders held or suspended therein fall on the inclined ioor H, and, sliding down on this floor, pass off through the conveyer E.

The letter i designates a vane, andj a windguard, both attached to the cap B. 'Ihe vane t' may have any usual or suitable shape, and is situated opposite to the wind-guard j, which consists of a plate partially surronmling the casing and projecting above its upper edge, as clearly shown. By the vane t the cap B is caused to turn with the wind, and since the vane always points in the direction of the wind it follows that the guardj is opposed thereto, the eii'ect of which is that the wind is not liable to rush into the top of the easing O and affect the uniformity of the draft.

What I claim as new, and desire to secure by Letters Patent, is-

l. In a spark-arrester, the combination of a smoke-pipe, a revolving cap projecting below the upper edge of such pipe, a casin g projecting above the lower edge of the cap, an inclined floor to the casing, and a conveyer eX- tending from the lower part of such iioor, all arranged to operate substantially as described.

2. In a spark-arrester, the combination of a smoke-pipe, a cap projecting below the upper edge of such pipe, a pivotal support for the cap, a casing projecting above the lower edge of the cap, an inclined ioor to the casing, a conveyer extending from the lower part of the casing, and a vane and wind-guard attached to the cap, all adapted to operate substantially as described.

In testimony that I claim the foregoing l have hereunto set my hand this 25th day of July, 1879. i

KARL FRIEDRICH WILHELM NEUIIAUS.
