CHIMNEY-SAFE.

'Specification of. Letters PatentNo.

To all whom t mayv concern.' y Be it known that I, GEORGE B. CLARKE, of Leonardsville,l Madison county', State of. New York, have invented anew anduseful Improvement in Chimney-Safes; and I .d0- hereby declare that the following is a full, clear, and exact description of the same.

The nature of my improvement consists in providing thelower part of the chimney with a smoke box, having a water tank be; low, and regulating dampers above; the point or points of'v entry of the smoke. l

To enable others skilled in the art to make. and luse my improvement, I will proceed lto describe its construct-ion and operation, reference being had to the annexed drawings forming a part of this specification, in which- Figure l, is a side sectional elevation of my improvement. Fig. 2, an end sectional elevation of the same. Fig. 3, a horizontal plan section of same;

Similar letters of reference indicate corresponding parts in the several figures.

A is the chimney composed of brick, in the usual manner, B the smoke box, C tank or receiver, D stove pipe tubes, E ,wire screen or fender, E hinged dampers, F vertical plate, J door of the smoke box. (a) apertures between the flange (b) of the smoke box B, and the chimney, (c) tube of receiver C.

TheV smoke box B open at the top, is placed under the chimney, its flanges (b) set in brick and mortar on the beams of the building,v the principal part ofthe box hanging below the floor of the chimney room. It is provided with a door J in the front side and one or more tubes D, for stove pipes in the other sides, the tubes, of different sizes, being cast in plates of equal sizes, permanently or removably secured in the lower part of the sides of the smoke box. The plates, if removable, may be vsecured by lianges at their corners or they may be keyed on to staples or hooks inthe castings, sothat tubes of various'sizes, set on plates of equal sizes may t the aperture in the smoke box. In setting the chimney,- care should be taken. to leave a portion of the rim or Hange (b) of the box outside the brick Work; the rim being slightly raised to receive water running down outside. Small apertures (a) should be left in the mortar next the rim, that the water may run into the box.

The tank or receiver C, issituated at the lowest. part of; the smoke box B. beinga part. of ltsmbottom, inthe form. of an inverted cone 1 terminating in a small tube (c) er1 nozzlewhich may loe-,stopped by ay cork: or faucet. The purpose? oruse of thetank or receiver appended tothe aforesaid smoke box is to hold water which lfrom -rainor condensed. smokev or other causef'may `run The water may-.be

down inside the box. drawn olf at thefaucet when .required, -f'or be guidedv by a tin orv lead of the building.

The regulators of thedraft, consist of two pipe toI the reary or more dampers ori' .trapk doors F",a.verti` &c. to fall down between'the surfaces of they dampers and the sides of the box within. By shutting down either of the dampers the draft can be greatly lessened vand in the case of burning of soot by accident in the chimney the most violent flame within may be deadened, if not quite suppressed by first quenching the fire in the stove below, and

then closing both dampers E or all of the dampers, if more than two are used, which may be done throughthe side door (J) of the smoke box; after which, the side door J should be shut,which will nearly close the draft of the chimney. The screen or fender y H is used when the dampers are open, to arrest falling brick and prevent them from disarranging the stove pipe. A cap should beuirmly set on either of the tubes D notoccupied by the stove pipe. The fender E is in two parts that it may be taken out, or replaced through the side door J of the smoke box. The vertical plate F is hinged to the fender to equalize the draft of opposite pipes. In some cases the regulators may be fastened on rotating rods passing through the front of the box so as to be operated without opening the side dooraforesaid.

The smoke-box device, described, forms a distinct intermediate chamber as pit were, and the dampers E E above and the coni cal or other equivalently 'shaped receiver C below the point of entry of thev smoke from the stove pipe D, combined, effect a considerable improvement in the draft et cetera,

lighting the re in the stove, and the smoke' box B be madieto-form a dry chamber, both above and below the points of entry of the smoke, that will greatly facilitate the draft on starting the fire, and any` after collection of wet, as the chimney becomes heated, may

i be allowed to remain inthe receiver C from whence it will 'be evaporated by the action of the heat and warmth of the casting and thus be made to assist the draft by the vapor rising from below the entry of the smoke; or, by closing the dampers E', in case of fire in the chimney arising from and kept up by burning pieces of paper, rags, or such like, drawn by the draft in a flaming condition from the stove, the vapor rising from the water in the receiver will rapidly extinguish the burning particles or pieces and by their falling into the water below, as well as i by the damping, by the vapor, of the smoke boX B when closed', all risk of the fire in the chimney' being renewed or breaking out again, on prematurely or soon opening the dampers E again, will be obviated.

I am aware that a narrow 'frame piece having a damper or valve has before 'been fitted in the chimney above the point of entry of the smoke, to reoulate the draft pers E above and a conical or other equiva lently shaped receiver C below the point or points of entry ofthe smoke as and for the purposes set forth.
