Specification of Letters Patent. Patented NOV. 11, 1919.

App1ication filed July 28, 1916. Serial No. 111,849.

To all whom it may concern: 7

Be it known that I, RAFAEL Es'rRAD-A, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Roof. Constructions, of which the following is a specification.

This invention relates to roof constructions in which certain portions of the roof surface are made higher than contiguous portions to provide accommodation for windows which are designed to admit sufficient light to the interior of train sheds and other buildings of the same general nature. In modern roof construction for housing large areas the development has been away from the use of high arched sheds which involve immense overhead framework and vast expanse of windows. The primary object of this invention is to provide an improved roof construction which provides a maximum amount of light to a large ground area,

inv'olves'a moderate outlay of materiah and which embodies an eflicient combination and arrangement of cantaliv'ers and beams for making the roof construction of minimum weight. Another object of the present in? vention' is to. provide an improved roof construction embodying window-containing monitors combined in an approved manner with flat roof sections, said monitors being mounted on a series of pillars'and suitably constructed to constitute cantalivers for supporting other roof portions which are disposed intermediately thereof. One of the objects of thepresent invention'is to provide an improved arrangement of window= containing monitors which .are adapted to provide light for the area covered by a flat roof supported by and between said monitors. Other and further objects will appear in the specification and be pointed out in the appended claims, reference being had to the accompanying drawings which exemplify my invention in an adaptation to a train shed.

In the drawings,

Figure 1 is a fragmentary perspective view of a train shed which embodies my improvements;

Fig. 2 is a partial vertical longitudinal section of the same;

Fig. 3 is a fragmentary vertical transverse section, showing the construction near one edge of the shed;

lars 1.

' Fig. llis a diagrammatic plan of a-train shed which is constructed in accordance with theprinciples of my invention.

Referring more particularly to the drawings, in the embodiment shown therein, pillars 1 are arranged in series ina number of rows which are preferably parallel. and the pillars of adjacent rowsof which are preferably'arranged in pairs as shown in the preferred embodiment. :Surmounting each of the pillars 1 is a double cantaliver 2. Surmounting each longitudinal series of pillars 1 and cantalivers 2 is a roof 3. Extending longitudinally of each series of pillars 1 and uniting the outer ends of the cantalivers 2'onrboth sides. are longitudinal beams l. The opposite lateral edges of the roof 3 and longitudinal beams 4: are rigidly connected by the double cantalivers 2 in such manner as to provide suitable frames for mounting window sashes 5 which arepreferably arranged at an inclination and may be opened for ventilation as shown in Fig. 1. While the

abovedescribed parts

1, 2, 3, and l may be constructed of any suitable component parts of members,:I have shown them on the drawings as comprising a monolith construction. It will be obvious from this description that the above numberedpartsjl to 4 inclusive constitute a rigid double canta liver framework, which together with the 7 window sashes 5 form a monitor shed extending lengthwise over each series of pil- The inclination of the window sashes 5 issuitably arranged to obtain the best lighting effects within the cars and over the platform space of the trainshed. The

longitudinal beams 4 which unite the outer ends of the cantalivers 2, adapt said cantalivers to better support the opposite ends of intermediately disposed simple beams 6, which are preferably deepest at their midlengths to form a peak 7 extending centrally and lengthwise of the roof section 8 which is supported by said beams 6. Similar beams 1 on the outermost cantaliver arms serve to connect the transverse beams 9 which carry inclined substantially flat roof sections 10 the outside edges of which are carried by a longitudinal wall 11 (see Fig. 3) provided with windows 12. As shown in Figs. 2 and 4c, a plurality of transverse beams 13 are disposed intermediately of each pair of beams 6 as well as intermediately of each pair of beams 9, the opposite ends of beams 13 being carried by the longitudinal beams 4 or by one of said beams 4 and an outside wall 11. WVhile the

beams

6, 9 and 13 and

roofs

8 and 10 may be made up of sections connected up in any suitable manner, I preferably employ the monolith construction throughout. By an inspection of Fig. I, it will be seen that between each quadrangle of pillars l is arranged a roof unit comprising two pairs of oppositely presented cantaliver arms, each pair of said arms being connected by a monitor roof and longitudinal beam to form a Window frame, and the oppositely disposed longitudinal beams l being also united with the

transverse beams

6 and 13 to form a roof section supporting frame work.

I claim:

1. In a roof construction, two parallel series of posts or pillars, an elongated roof section of relatively small lateral extent raised above and centrally disposed with respect to each seriesof posts or pillars, cantaliver beams or partitions supported by said posts or pillars and supporting said elongated roof sections, each of said beams or partitions being of relatively greater lateral extent than said roof section and having upper edges inclined outwardly and clownwardly from the outer edges of said elongated roof sections to a horizontal plane corresponding to the upper ends of said posts or pillars, longitudinal beams connecting the outer ends of said cantaliver beams or edges of said cantalivers, longitudinal beams connecting the outer ends of said cantalivers and forming Window openings between the lateral edges of said roof section and the inclined upper edges of said cantalivers, and window sashes for said openings.

3. In a roof construction, a longitudinal series of posts or pillars, double cantalivers transversely arranged at the tops of said posts or pillars, said double cantalivers having upper edges extending upwardly and inwardly toward the central vertical plane of said series of posts or pillars, an elongated roof surmounting said cantalivers, longitudinal beams connecting the outer ends of said cantalivers, whereby upwardly and outwardly presented light and ventilating openings are formed between the lateral edges of said roof, the upper. edges of said cantalivers, and said longitudinal beams, a roof section supported along one edge by one of said longitudinal beams, the last.

mentioned roof section being arranged substantially within the horizontal plane including said longitudinal beam, and means for supporting the other longitudinal edge of the last mentioned roof section.

4. In a roof construction, an elongated monitor comprising transverse frames or walls which increase in width from top to bottom of said monitor, longitudinal beams connecting the outer ends of said transverse frames or walls, longitudinally extending means for connecting said frames or walls at the top, window sashes inclined upwardly and inwardly fromsaid longitudinal beams toward said connecting means at the top, means for supporting said monitor, a substantially flat roof section supported along one edge by one of said longitudinal beams, and means for supporting the other edge of said fiat roof section.
