UNITED srATEs N PATENT- formon GEO. D. GREENLEAF, OF CHATEAUGAY, YORK.
VENTILATQR.
Application of Letters Patent No. 24,387, dated June 14, 1859.
To all whom it 'may concer/n:
Be it known that I, GEORGE D. .GREEN- LEAF, of Chateaugay, in the county of Franklin and State of New York, have invented a new and Improved Ventilator; and
- I-do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a vertical central section of my invention. Fig. 2, is a plan or top view of the same. Fig. 3, an inverted plan of the same.
Similar letters of reference indicate corresponding parts in the several figures.
This invention relates to a novel way of ventilating apartments that are heated by stoves. The objectof the invention is to ventilate such apartments by allowing the impure air to escape into the pipe of the stove by which the apartment is heated, the impure air escaping through the stove pipe together with the products of combustion from the stove. The invention consists in the peculiar means employed for effecting such result as will be hereinafter fully shown and described.
To enable those skilled in the art to fully understand and construct my invention I will proceed t-o describe it.
A, represents a sheet metal cylinder which is inserted in the ceiling of the apartment to be ventilated or in a partition thereof at any point where the stove pipe is to pass through.
B, is a cast metal plate which is provided at its under side near its edge with an annu lar flanch a, around which the upper end of the cylinder A, is iitted, the plate B, resting on the flooring C, immediately above the apartment to be ventilated, see Fig. l.
D, is a cast metal plate which is provided at its upper side with an annular ianch b, around which the lower end of cylinder A, fits, said plate D, being against the ceiling E, of the apartment to be ventilated, the cylinder A, being made of a length or depth to correspond to the thickness of theflooring C, ceiling E, and the space between them. The plate D, has holes or openings c, made in it, as shown in Fig. 3, and on the upper surface of plate D, within the flanch Z1, a circular plate F, is placed, said plate F,
having holes d, made through it corresponding to the holes 0, in plate D, and forming a register. The plate F, is turned by means of a pendant e, which projects down through one of the holes or openings c, in plate D.
G, is a bell-shaped casting which is fitted within the cylinder A, and has its lower edge rest-ing on the plate D. The plate D, is secured to this casting G, by means of hooks e, attached to the flanch b, said hooks tting over inclined projections f, on the outer side of the casting. The upper end of the casting G, is provided with or terminates in a neck g, of such diameter as to receive the end of the stove pipe A, above the flooring C, and on the neck g, spiral flanches 72 are formed or attached, underneath which flanches, projecting corners at the edges of the opening in plate B, bear, see more particularly Fig. 2. Near the center of plate D, there is an annular iianch y', said anch forming the boundary of an opening in which the stove pipe H, fits, said pipe H, leading from the stove andextending upward within the chamber I, formed by the casting G, nearly to the neck g, a space 7c, being allowed between the orifice of pipe H, and the neck to admit the upper stove pipe A', to communicate with chamber I, which is formed by the bell-shaped casting Gr, as shown clearly in Fig. l. On the flanch y', a cup J, is fitted. This cup may be construct ed of sheet metal and its upper edge extends outward to within a short distance of the inner sides of the casting G. To the -inner side of the upper part of the casting Gr, plates Z, are attached to serve as bearings for the upper end of pipe H, and retain said pipe in proper position.
From the above description it will be seen that this invention serves to protect the wood work in the ceiling from the heat oi the stove pipe, for the space between the bell-shaped casting Gr, and cylinder A, communicates with the external air by opening ax, around the neck g, of the cast-ing and it will also be seen that by adjusting the plate or register F, the foul air in a room may escape through the holes e, d, into the chamber I, and thence into the pipe A', atI the same time the smoke from the stove ascends freely up the pipes H, A. The cup J, catches all soot that may fall from A. The casting G, is secured to the plate D, by turnfit snugly under the hooks e', and the plate shaped casting G, and plates B, D,- the cup 10 B, is tlrned si thlat its prlojelctiorlls ,hwhicll J, and register F for the purpose specified: are un erneut tle spira anc es Wi draw the p1ateD,snug1y aganstthe ceiling E.
