Letters Patent No. 86,413, dated February 2, 1869.
IMPROVEMENT IN VENTILATORS.
v The Schedule referred to in these Letters Patent amd4 making part of the same.
To allwhom fit ma/y concern:
Be it known that I, HENRY KELLEY, of Boston, in the county of Suffolk, and State of Massachusetts, have invented a new and useful Improved Ventilator; and I do hereby declare the following to be a full, clear, and eXact description ofthe construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in Which- Figure l represents au elevation seen from the in-A side ofan apartment.
Figure 2 represents a vertical section on line x x.
This invention consists of two series of glass plates, 7the one, A, being simple strips of glass, and are made movable by means lof cord a, to open or close the bevelled aperture in o-ute'i1 plates B, both plates being secured in the sash-bars, C, of an ordinary' Window.
The outer series may be secured to the sash-bars C in the ordinary Way with putty, or, for convenience, with a strip of wood or metal. i
In the outer series the plates B B B B are bevelled, as seen at c c, so as to allow the impure or infected an' to pass out, and the out-,door pure air to enter the apartment when the ventilator is open, without creating a direct draught through the apartment,
Strips D, in which are secured the inner series of plates A A A A, are placed on either side of device,
and made hollow, to receive the spiral spring d, which, together with the pin f' f', acting on the lower sashbar, serve to close the aperture b, when the catch e is released, by means of the cord f, from the slot in the metal plate g of the sash-bar O.
The device, as described above, is intended to serve as a substitute for the usual method of Ventilating rooms by means of lowering or raising windows, and may also be used instead of ordinary ventilators in walls.
IVhat I claim as new, and desire to secure by Letters Patent, is-
l. A series of plates, B B B B, bevelled, as shown indrawings b, arranged substantially as and for the purpose herein set forth. p y 2. The plates A A A A, in combination With plates B B B B, to close the apertures formed by bevelled plates B B B B.
In testimony whereof, VI have signed my naine to this specification, in the presence of two subscribing Witnesses.
