MAURICE I. JACOBS, OF BROOKLYN, NEW "YORK.

GREENHOUSE CONSTRUCTION.

Application filed. October 9, 1913.

To all whom it may concern.

Be it known that l, MAURICE I. JAooBs, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Greenhouse Con struction; and T do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper tains to make and use the same.

This invention relates to greenhouse construction and more particularly to that type wherein a metal frame is used to support the roof, and in which the metal frame permits a curved eave to be formed.

An object of this invention is to provide an inner skeleton structure of metal, and an outer pane-supporting structure made up of wooden rails overlaid by metallic reinforcing strips or bars to prevent warping and undue expansion of the rails.

A further object of the invention is to provide means for spacing said rails slightly from the uprights of the inner skeleton structure so as to allow the wood to swell while still preventing it from warping.

Further objects will be apparent from the following specification, appended claim and drawings, in which;

Figure 1 is a side elevation of a portion of the structure showing the glass in section Fig, 2 is an end elevation thereof, Fig. 3 is a sectional view as on the line 8-3 of Fig. 1, Fig. 4. is a sectional view showing how the roof and side bars are secured above the side posts and rafters, and, Fig. 5 is a detail perspective view of a portion of this construction.

In a construction of greenhouses in accordance with this invention, it is possible to form a side wall and roof having a curved eave which in fact presents a continuous surface of the side wall and roof. Furthermore it is possible to construct a greenhouse more cheaply along the lines of this invention as provision is made to use compact fittings for the several parts and to use straight grained timber which is properly reinforced at the necessary points.

Referring to the drawings there is shown a base 10 which may be of concrete or any other form of construction. A sill 11 is mounted upon this base upon which the framework may be erected or as shown at 12, the sill may have an opening formed Specification of Letters Patent.

Patented 13cc. 28, 1915.

Serial No. 784,348.

therein to admit the lower end of a side bar 18, which may be embedded in the base 10. The lower end of the side post 18 may be secured in a step 14- and this step may be secured to the upper face of the sill 11 if desired. The upper end of the side post 13 fits in a socket 15 formed in the lower end of a curved member 16, and the upper end of the side post may be held in the socket 15 by rivets or any other fastening means shown at 17.

The member 16 is curved to the desired degree and has the upper end thereof recessed as at 18 to receive the lower end of the rafter 19 which may be riveted or otherwise secured as at 20. The side posts and rafters may be repeated as many times as desired and may be spaced apart at desired intervals. As roof bars and side bars for the glass are to be supported by these side posts and rafters and as the side bars and roof bars will be positioned closer together, it is necessary to provide a support intermediate of the side posts and rafters for the intermediate side bars and roof bars. To support the purlins 23 I provide fittings 21 which have flanges to receive the fastening means 17 and 20 to secure said fittings to the side posts and rafters and these fittings have flanges 22 to which the purlins 23 are riveted or otherwise secured. These fittings also have extensions 24 which are perforated as at 2? to receive bolts or other fastening means 26. Each side post, curved member 16 and rafter 19 has a side bar 27 disposed adiacent to the outer edge thereof, which side bars are curved as at 28 to conform with the curved member 16 and the roof bar 29 which abuts against the outer end of the side bar 27. The side bar 27 may be of straight grained timber which is curved as at 28 by steaming or any other known means for permitting the shaping of the side bar and as shown in Fig. 41, the ad jacent ends of the bars 27 and 29 are held in fixed position by bolts 26 which pass through the cars 24 of the fittings 21. Fig. 1 also shows by dotted lines that the side posts are supported at the point of tangency with the curved portion 28.

The side bar 27 and roof bar 29 as shown in Fig. 1 of the drawings are not the bars which are adjacent to the side posts 13, the curved member 16 and rafter 19, as those bars are in advance of the side posts, curved member and rafter and it will be seen that these side and .I'OQf bars are secured as by bolts or other fastening means 30 to the purlins 23. The roof bar and side bar are recessed as at 31 to form gutters in which condensate from the glass is collected and carried to the sill.

The side and roof bars are of the cross sectional shape shown in Fig. 3 of the drawings as a result of which a reduced portion is formed to present the recessed portions in which the edges of the sections of glass 33 are fitted. The glass is retained in this fixed position by-clamps 34 which are suiiiciently flexible to allow for expansion and contraction of the glass and these clamps are held by reintorcing bars 35 which may be strips of iron or other desired material of sustaining strength for retaining the curvature of the portions 28. The strips are secured to the side and roof bars by screws or other fastening means 36. The abutting edges of the plates of glass may be provided with lead or other unions 37.

Various modifications may be made Within Copies of this patent may be obtained for five cents each, by addressing the scope of this invention without departing from the spirit thereof and the drawings are submitted for illustrative purposes only.

Having thus described my invention 1 claim:

In a greenhouse, an inner metallic skeleton structure comprising uprights consisting of posts, rafters, and means connecting them, and horizontal purlins connecting the uprights and projecting beyond their outer edges; combined with an outer pane-supporting structure con'iprising upright wooden rails paralleling said metal uprights and overlying the purlins, and metal reinforcing bars secured along the outer faces of said rails, thereby preventing the wooden rails from warping, for the purpose set forth.

In testimony whereof I atlix my signature in presence of two witnesses.

MAURICE I. JACOBS.
