UNITED STATES PATENT OFFICE.
JOHN M. LUTZ, OF PHILADELPHIA, PENNSYLVANIA.
SKYLIGHT.
SPECIFICATION forming part of Letters Patent No. 244,136, dated July 12, 1881. Application filed March 1G, 1881. (No model.)
To all whom 'it may concern:
Be it known that I, J oHN M. LUtrz, a citizen of the United States, residing in the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful lmprovement in Skylights, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure l is a side elevation of the skylight embodying my invention. Fig. 2 is a central vertical section thereof in line :t x, Fig. 3. Fig. 3 is a bottom plan thereof.
Similar letters of reference indicate corresponding parts in the several figures.
My invention consists of a skylight the frame whereof communicates with the ventilator-shaft by meansof hollow bars provided with perforations, substantially as will be hereinafter set forth.
Referring to the drawings, A represents the frame'of the skylight, formed of metal consisting of upwardly-inclined bars aand base-bars b, the former rising from the latter and connected to the top shaft, B, the bars and base supporting the glazing. The bars a are hollow and communicate with said shaft B, and are likewise perforated, as at a', in order to communicate with the apartment, as morev readily shown in Figs. 2 and 3. Within the shaft is a valve, C, which is hung on a horizontal axis above the inlet-openin gs a of the shaft B, and provided with rods, cords, 0r other appliances, c, conveniently accessible for opening and closing the valve.
The operation is as follows When the apartment'is to be ventilated the valve Gis opened and the heated or impure matters enter the shaft B, and also the hollow bars a, and so reach the discharge-shaft B, from whence they escape to the atmosphere.
It will be seen that I provide increased means of exit of the heated or impure matters, Afor as soon as they reach the base of the skylight the perforated bars a act as a conduit for the same and carry them to the shaft B, and as the latter is opened and the frame, as glazed, is of tapering form, the forcible discharge of the matters is occasioned. As each of these bars a is a hollow tube, the number of passages or spaces emptying into the shaft O is considerably increased. If these bars were solid, the air could not pass through them to the shaft. The holes a enable it to rush into each tubular bar a at many points, and it passes violently out of said bars into the shaft O, thus increasing the draft through the shaft. These increased facilities of exit are very desirable, since the air under the glass cover or roof is heated intensely by the sun. Fresh air may enter the shaft B, and some of it may pass into the bars a, and thus enter the apartment. The shaft B is guarded at top by a hood, guard, or cap, D, and the bars have their upper edges covered with plates or bars d.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
A skylight having a frame consisting of base-bars and hollow upwardly-inclined bars. and provided with a hollow top shaft, each of the upwardly-inclined bars beingprovided with a series of openings, a act, which openinto the apartment, and with an upper end opening, a, which communicates with said shaft, substantially as set forth.
