SPECIFICATION forming part of Letters Patent No. 749,972, dated January 19, 1904.
Application filed August 14:, 1903. Serial No. 169,471.. (No model.)
To all whom it rim/y concern:
Be it known that I, HARRY SIMPSON, acitizen of the United States, residing at Edgely, in the act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to greenhouse-frames; and it has for its object to provide a simple and durable construction which will permit of building the greenhouse-roof entirely of metal and glass.
A further object of the invention is to provide a construction and arrangement which will hold the glass securely in place and in which drip-troughs may be attached wherever desired.
Other objects and advantages of the invention will be understood from the following description.
1n the drawings forming a portion of this specification, in which like numerals of reference indicate similar parts in the several views, Figure 1 is a transverse section through a gutter and the glass of a greenhouse-roof, the bar and the glass-retaining clamps being shown in elevation. through one of the bars and a glass-retaining clamp with the glass held thereby and showing in elevation a hanger connected tothe bar and by means of which the drip-trough is suspended. Fig. 3 is an enlarged side elevation of a portion of a rail and hanger and retaining-clamp, the overlapping portions of two sheets of glass being shown in section. Fig. 4 is a detail perspective view of the retainingclamp. Fig. 5 is a perspective view showing the lower end portion of one of the bars of the frame, illustrating the manner in Which the flanges are cut away, also the manner in which each flange is notched to accommodate a sister hook.
Referring now to the drawings, there is shown a portion of the roof of a greenhouse comprising a gutter 5, the sides of which are bent to form seats 6, beyond which said sides are bent downwardly and then outwardly and Fig. 2 is a transverse section.
the under side thereof is a vertical collar 8,
'which is threaded for engagement with the threaded upper end of the usual post, it being understood that thethreads may be omitted, if desired.
In connection with the gutter 5 there are employed bars 9, each consisting of a vertical web having flanges 10 and 11 at its lower edge and at opposite sides, these flanges diverging upwardly and forming between them and the web of the rail channels 12 and 13, which are designed to receive putty. The lower ends of the'bars 9 have their flanged lower edges cut away, and the resultant shoulders 14 are disposed upon the seats 6, while the adjacent ends 'of the flanged portions rest upon the inner sides of the troughs 7 To further support the troughs 7 hangers are employed in the form of sister hooks 15 and 16, which are engaged over the flanges 10 and 11, which are notched at such points of engagement, so that said sister hooks may lie flush with the upper edges of the flanges at the sides of the hooks. The sister hooks are bolted against the inner sides of the troughs 7 by meansof the bolts 17, as illustrated.
The plates or sheets of glass 18 are disposed upon theputty that is filled in the channels 12 and .13, the edges of the adjacent sheets or plates being overlapped, as illustrated. To
hold the plates snugly down against the putty,
so as to prevent leakage between the plates and the rails, retaining-clamps are employed. Each of the retaining-clamps consists of a U- shaped plate, which is disposed over the bar, to which it is held by meansof a set-screw 19, the lower ends of the spaced members of the U-shaped plate being notched or stepped, as shown at 20, so that they may rest upon both plates of glass where they overlap, and thus hold them securely in place. With this construction it will be seen that the water that falls upon the roof willdrain between the bars and over the glass to the gutter 5 and that any drip from the glass and bars will run down and finally be caught in the troughs 7. With this arrangement, moreover, there is rod employed only metal and glass,while the parts are held with security and rigidity.
It will be understood that drip-troughs may be suspended by means of the hangers wherever desired, it being understood that in practice modifications of the specific construction shown may be made within the scope of the claims and that any suitable materials and proportions maybe used for the various parts without departing from the spirit of the invention.
\V hat is claimed is A greenhouse-frame comprising a gutter having longitudinal troughs at its side edges
