Be it known that I, GEORGE WARNER, of the city of Cleveland, in the county of Cuyahoga, in the State of Ohio, have invented a new and improved Cap for Marine-Stove Pipe, which is to prevent cook'and other stoves used en hoardvessels from smoking; andAI do hereby declare that the following is a full and exact description thereof, reference being hadto-the'aceompanying drawings, and to the letters of reference marked thereon. i

Figure 1 is a perspective view, and

Figure 2 is a section-of the same.

The same letters refer to like parts. 1

Letter A is a sheet-iron cap, with a conical or dat top, as may be desirable, and with an opening on one side, for the smoke to escape. The letters B B are two iiexible shields, attached, by hinged joints, to each side ofthe openingin the cap.- The letter C is-a top shield, iirmly attached to the cap above the opening, and made to press upon the top of side shields B B, thereby retaining them in any position desired. The outer edge of this shield maybe corrugated, thereby giving greater irmnessto the shields. The letters D D are two handles, used to adjust the cap to anydesired position. The letter E is ,a dat cast-iron ring, with a projecting iiange, F. This ring is fastened to the-deck G, and serves to hold the stove-pipe, from below, but not showninthe drawing. The projecting flange F is used to hold the cap A in proper connection with the stove-pipe.

I4 construct my cap ofv sheet iron, and in a manner familiar to all` mechanics who are accustomed to make stove-pipe and other constructions which-require similar mechanical manipulation.

, The general operation or adjustment of my cap is secured by hand.' The necessity for this is owing to the fact that most of the stoves 'on board sailing-vessels are placed nearly under some of the fore-andaft sails. The wind, Ywhen it strikes these sails, is forced downward, which, of course, would carry the smoke with it, through the stove-pipe, into the cooks room, 'or into the cabin, as the case may be. Hence, any device which depends upon the force of the wind, bythe means of a weather-vane, to place the smoke-cap' in la proper position to cause the smoke to freely escape will fail. i

Il' I wish to have my cap adjusted by means of a weather-vane, I can do so by a spindle passing up from the stove-pipe,'and reaching the cap in the apexvof the conical top. Inthis case, the cap should be made some larger than' the pipe below, in order that it muy turn easily; but,las I before said, its general adjustment is by hand. The two handles D D serve for this purpose. It must not be very high above the deck, otherwise it would be in the way oi'- the proper management of the sailsg: and, indeed, it frequently happens that thevcap has to be taken temporarily from its place, in order to handle the sails. The use of my smoke-cap does away with the heavy basket-made'guards which are placed over the top of the stove-pipes.

-In consequence of the before-mentioned 'act of the downward course of the wind when it strikes the sails, I use the top shield C, with 'a ddwnward inclination, and projecting some little distance from the top of the opening in the cap, whereby I cause thewind to force the smoke from outof the stove-pipe. I attach the smokecap to the projectingange F in such a mannerthat the directcurrent of wind will strike it on its closed side.' This position should cause the smoke to be discharged freely through the opening; but, in consequence of the wind striking so many impediments on the vessel, such is not'the fact. I have, therefore, attached, by hinged joints, to the side of the opening in the smokecap, the side shields B B. These shields are held in any desired k position by the pressure of the top shield upon their top edges; anch-when the front edge of the top shield is corrugated, it `helps to hold the side shields more tirmly in their places. It is not necessary always to place these side shields in line with the direct current of wind, 'but they should be s o adjusted as to cause the wind to pass by the opening, and, of course,lto the smoke along with it. Thus, by having a smoke-cap adjustable by hand, Ivcan provide against any and all contingencies of working the sails. 'l With the top shield and the two vside shields, I can govern all and every current oi' wind, so as to prevent the smoking of cool: or'other stoves used ou board vessels.

` I disclaim cylindrical smoke-cap or wind-guard for stoye-ppes, for this is common; nor do I claim any of the usual appendages made use of in constructing the head of a wind-sail; but

What I- do claim, and Wish to secure by Lett ers Patent, isv .A The top shield G and the two flexible side shields B B, in combination with the cap A, as described, and when used in` the marinier and for the purposes sei: forth,

GEORGE WARNER. Witnesses F. B. PRATT, F. D. PRATT.
