UNITED STATES PATENT OFFICE.

LYMAN A. GOUOH, OF YONKERS, NEW YORK.

VENTlLATlNG-SCUTTLE FOR BUILDINGS, 84C.

SPECIFICATION forming part of Letters Patent No. 241,972, dated May 24:, 1881.

1 Application filed December 11, 1880. (No model.)

To all whom it may concern:

Be it known that I, LYMAN A. Goocn, of Yonkers, in the county of Wes'tchester and State of New York, have invented certain new and useful Improvements in Ventilating-Scuttles for Buildings, &c., of which the following is a specification.

The object of my invention is to provide means whereby a constant outward and upward ventilating current or currents may take place through a scuttle leading from any building or from any compartment of a vessel without danger of damage being done by incoming rain or snow.

To this end the invention consists in the combination, with a scuttle in a building or vessel, of a pan or tray arranged at some distance below the scuttle and serving to catch rain or snow, affording a free opening for Ventilation between said pan or tray and said scuttle. The pan or tray may be composed of any material, and, preferably, has a glass or other translucent bottom, so that it may afford provision for Ventilation, and also serve the purpose of a skylight.

It also consists in the combination of such scuttle and pan or tray, arranged below the same and affording a free opening between it and the scutile,of horizontal ways or guides, by which the pan or tray is supported, and along which it may be adjusted to permit access to the roof through said scuttle.

It also consists in a novel arrangement of mechanism for so moving said scuttle along said ways. I

In the accom pan yin g drawings, Figure 1 represents a vertical section through a scuttleopening and a roof and attic-floor having my invention applied thereto, and Fig. 2 represents a similar section at right angles to Fig. 1.

Similar letters of reference designate corresponding parts in both the figures.

A designates a portion of the roof, and B designates the attic-floor, of an ordinary dwelling-house.

G designates an ordinary scuttle, save that it is intended generally to be left open antL need not be provided with any cover; and I) designates a pan'or tray arranged at some little distance below the scuttle, leaving a free and uninterrupted opening-between the pan or than the scuttle, so that rain or snow beating in at an angle, as shown by broken lines in Fig. 1, will strike upon it and not go beyond the edge or edges thereof.

The pan or tray D may be constructed in any suitable manner, with a raised edge or frame that will catch the snow and rain and prevent the water from leaking down through the floor of the attic.

The marginal frame b is raised above the bottom 0; and in this example of my invention the bottom is composed of a sheet of glass or other translucent material, so that the pan or tray serves also as a skylight and transmits light freely through it.

In the attic-floor is an opening, B, and all foul and hot air, instead of accumulating in the attic, as heretofore, will pass, as indicated by the arrows, around the edge of the pan or tray D and out at the scuttle, the upward and outward current or currents being aided by the evaporation of any water that may have accumulated in the pan or tray.

The air or ventilating pipes E from waste and sewer pipes, instead of passing directly through the roof, as heretofore, may all terminate in the attic, as shown, and the air and gases will pass from them and be carried through the scuttle by the upward and outward current or currents.

The pan or trayD might be fixed rigidly be low the scuttle 0 when the latter is to be used simply as a ventilatingscuttle; but in order to afford access to the roof through the.scuttle when desirable, I have arranged the pan or tray in guides or ways F, in which it may move horizontally.

The guides or ways F may be attached to pieces F, by which they are suspended from the roof, or they may be supported in any other suitable manner. The pan or tray may engage with its guides or ways in any suitable manner. As here shown, the frame I) of the pan or tray is provided at each side with atongue, I), which enters a corresponding groove in the guide or way and prevents the pan or tray being moved up or down to displace it. At one side of the scuttle the guides or ways F might be cutaway at the top, so as to permit the pan or tray, when adjusted to one side, to be lifted out of them to enable it to be readily cleaned. As represented in Fig. 2,the pan or tray D is arranged to move toward the left.

In order to enable the pan or tray to be readily moved from a lower room in the house I connect with each end thereof a cord or other flexible connection, d, which passes over a pulley, e, supported in any suitable manner, and extends downward. To prevent the cords d from being cut by burglars near their attachment to the pan or tray D, I fix to each end of the said pan or tray a metal rod, f, to which the cord d is fastened, and when thus arranged the cord will never come near enough to the scuttle to be cut by burglars.

By my invention I produce a means of ventilation that operates well either in pleasant or stormy weather, which is very simple and easily applied to any scuttle, and which is applicable todwelling-houses,theaters,public schools,and other public buildings and churches.

My invention is also particularly desirable for ventilating the compartments ot'passengervessels and for ventilating the coal-bunkers of vessels, in which oftentimes fires have been started by spontaneous combustion or explosion of gas collected therein from the want of ventilation.

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

1. The combination, with a scuttle, of a pan or tray arranged at some distance below the same and affording a free opening for ventilation between said pan or tray and said scuttle, substantially asspeeified.

2. The combination, with a scuttle, of a pan or tray arranged at some distance below the same and constructed with a translucent bottom, and affording a free opening for ventilation between said pan or tray and said scuttle, substantially as specified.

3. The combination, with a scuttle, of a pan or tray arranged at some distance below the same and affording a free opening between said pan or tray and said scuttle, and guides or ways, along which said pan or tray can be moved to one side of the scuttle, substantially as specified.

4. The combination, with a scuttle, ot' a pan or tray arranged at some distance below the same and ati'ording a free opening between said pan or tray and said scuttle, guides or ways for said pan or tray, metal rods projecting from each end of said pan or tray, and cords or other flexible connections attached to said rods and extending down over pulleys, substantially as specified.
