SKYLIGHT.

SPECIFICATION forming part of Letters Patent No. 311,245, dated January 27, 1885.

Application filed October 20, 1884.

To all whom it may concern.-

Be it known that I, EDUARD HENN, of J ersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Skylights, of which the following is a specification.

This invention has reference to improvements in skylights,whereby the same may be usedfor ventilating purposes; and the invention consists of a stationary base or support having side guide-rails, and of a movable skylight that is supported by antifriction rollers, and guided on said side rails and secured in closed position to the base by means of a locking mechanism that can be opened or closed by means of connecting-cords and pulleys from any story of the building. By additional cords and pulleys the movable skylight can be moved laterally over the side rails and thrown into open or closed position. The movable section of the skylight is provided at the ends with transverse hinged and spring-actuated guard-plates, to prevent the entrance of rain. A ventilating-tube is arranged at the top of the movable section and provided with a valve operated by a cord from a pulley.

In the accompanying drawings, Figures 1 and 2 represent side elevations of my improved skylight guided on arc-shaped rails,

and shown, respectively, in closed and open position. Fig. 2 is a side view of a skylight guided on straight rails. Fig. 3 is a vertical longitudinal section; Fig. 4, a bottom view; Fig. 5, a vertical transverse section of the same; and Figs. 6 and 7 are detail views of the locking device of the skylight.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the stationary portion or base of my improved skylight, which is made of wood. with a sheet' metal covering, and secured to the roof in the usual manner. The base A is provided at its longer sides with straight or arc-shaped guiderails or a, on which rests the'movable skylight B by means of anti-friction rollers a a, as shown in Fig. 3. The movable skylight B is constructed of a rectangular base-frame, I), having straight or arc-shaped sides b and the building.

(No model.)

straight transverse ends b inclined stays If, and a smaller top frame, I), the base-frame, stays, and top frame supporting the glass panes through which the light is admitted to the building. The movable skylight B is provided at its ends with hinged and spring-actuated guard-plates B, which plates are bent outwardly at their lower ends. The guard plates B have flanges d d", that extend over the side walls of the base A, and which serve, 6c in connection with the guard-plates, for the purpose of preventing the entrance of rain between the base A and the movable skylight B. The sides I) of the base-frame b of the skylight B aremade U-shaped, so as to extend aropnd the guide-rails a a and be guided thereon. They are also provided with lateral flanges 12 that protect to some extent the sides bof the skylight against the rain. The movable skylight B is locked in position on the base A by a locking device, 0, that is attached to a transverse center bar, f, of the skylight B. The locking device consists of a slide-bolt, d, that enters the projecting lugs cl of one of the side rails a. The slide-bolt d is provided at its rear end with a T-piece, (Z and connected by spiral springs d to a fixed flange of the center bar. A fulcrumed lever, e, engages by its forked end the T-piece d of the slide-bolt d equidistantly from its center, so as to pull the same back when the forked lever e is moved in either direction, as shown in Fig. 7. The opposite end of the forked lever e is provided with an eye, 0', to which are connected two cords, 0 that extend in opposite directions fromthe locking device and pass over guide-pulleys e of the base A downward into By pulling either one of the cords e the locking device 0 can be opened, and thereby the movable skylight B released 0 from the stationary base A.

In place of the locking device described any other locking mechanism may be used, as I do not confine myself to the special construc tion shown. The center bar, f, of the skylight B has a fixed eye, f, to which are applied two oords, f", which extend in opposite directions to each other, and which are guided by pulleys f a of the base A downward through the building. The cords f serve to move the movable skylight Bin either direction over the base A after the locking device Chas been released, so that a large ventilating-opening is obtained, as shown in 2. IVhen it is desired to close the skylight, the opposite cord, f, is pulled, and thereby the skylight returned into closed position until the slide-bolt re-engages the locking-lugs of the base A, and relocks thereby the skylight B. The anti friction rollers a of the movable skylight B facilitate the moving of the skylight B into open or closed position without too great a strain on the operating-cords f By opening the skylight B one guard-plate, B, is guided over the side rails b b, and placed into inclined position, as shown in Fig. 2. The guard-plate B is returned into its normal position by its spiral springs when the skylight B is returned into closed position as shown in Fig. 2. The top frame, I)", of the skylight B is provided with a ventilating-tube, D, having exterior openings and a flanged surmounting cap to prevent ingress of rain. At the inner end of the ventilatingtubel) is arranged a centrally-pivoted valve, D, the pivot of which is extended through the tube D and provided with cranks, to one of which is attached a cord, g, for opening the valve, while to the other smaller crank is attached aspiral spring, by which the valve is returned into closed position. By pulling the cord 9 and fastening the lower end of the same the valve D is held in open position, so as to permit the hot air that rises to the skylight to pass to the outside.

The operating-cords may be dispensed with whenever a cheap and simple construction of skylight is desired. In this case a person has to go up to the skylight, release the locking mechanism, and push the movable portion to either side of the base.

My improved skylight is preferably made of metal, so as to prevent warping, and secure thereby the easy regular working of the same at all seasons.

WVhenever change of air and ventilation is required, the movable skylight is moved into a more or less open position by first releasing the locking mechanism and then pulling it to either side of the base. In this manner a convenient means of ventilating staircases and light-shafts of buildings during the summer season is obtained.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of a stationary base, a movable skylight supported thereon having hinged and spring-actuated end guardplates, a locking device for locking the skylight in closed position to the base, means for releasing the locking device, and means for moving the skylight into open or closed position, substantially as set forth.

2. The combination ofa stationary base having side guide-rails,a movable skylight guided by anti-friction rollers on the base, and having hinged and springactuated end guard-plates, a locking device, means for releasing the locking device, and means for moving the skylight into open or closed position, substantially as set forth.

3. The combination of a stationary base, a movable skylight supported thereon, and provided with hinged and spring-actuated guard plates at the ends, and means for locking the skylight in closed position, substantially as set forth.

4. The combination ofa stationary base having side guide-rails, a movable skylight having anti-friction rollers and U-shaped side rails, means for locking the skylight in closed position, cords connected to the locking device forunlocking the same, and cords connected to the transverse center bar of the skylight for moving the same into open or closed position after the locking device has been released, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in pres ence of two subscribing witnesses.

EDUARD HENN.
