2 Claims.

My invention relates to a hangerfor an eaves trough or the like, and more particularly to a new and improved type of clamp that securely locks the hanger to the trough.

An object of the invention is to provide a new and improved type of clamp adapted to secure a hanger to a trough in a simple and practical manner and to prevent slippage between the hanger and the trough.

A further object of the invention is to provide a new and improved type of clamp, which is particularly applicable to a simple and inexpensive design of hanger extending from the roof substantially across the open face of the trough to the edge thereof, and which eflectively clamps this edge of the trough thereto, so as to form a substantial interlocking action that holds the trough securely in position.

It will be noted that the improved type of clamp 20 involves essentially a single integral strap hanger having a trough engaging end formed to hook over the edge of the trough and a locking element adapted to be compressed against the trough so as firmly to engage the trough and lock the hanger thereto, whereby to prevent lateral slippage along the trough or disengagement of the hanger from the trough.

Other objects and advantages of the invention will be apparent from the following description taken in connection with the accompanying drawing which forms a part thereof.

In the drawing:

Figure 1 is a perspective of a portion of roof construction illustrating a hanger embodying the 35 invention supporting a trough.

Fig. 2 is a similar but enlarged View of the hanger and trough only, illustrating the manner in which the hanger is readily clamped to the trough but before the locking lug is pressed against the outer edge of the trough.

Fig. 3 is a side elevation to show in detail the trough engaging portion or" the hanger and the outer edge of the trough in their relation as shown in Fig. 2.

Fig. 4 is a similar view, but illustrating the lug pressed against the outer edge of the trough.

Fig. 5 is a perspective illustrating how the lug orimps a portion or" the outer edge of the trough into the aperture in the trough engaging portion 50 so as to lock the hanger securely to the trough.

Fig. 6 illustrates an alternative embodiment of the invention.

Fig. 7 illustrates another embodiment of the invention.

The hanger embodying the present invention comprises generally a roof engaging bar 2 and a trough engaging portion 3. Trough engaging portion 3 is formed at the outer end of roof enaging bar 2. Roof engaging bar 2 is preferably a single integral strap adapted to be secured to the roof, as illustrated in Fig. l, and to extend outwardly from the roof across the open face of trough 5.

trough may have many different shapes or designs, but the design shown in Fig. 1, being iliustrative only of a preferred form to show a ready adaptation of the invention, has a vertical rear wall 6 adapted to lie against the eaves-edge of the roof, and a horizontal flat surface or flange along its outer edge 3. By extending the roof engaging bar outwardly from the roof across the open face of trough 5, in the form of a simple integral strap, the outer end of this hanger may be formed into an exceedingly simple and inexpensive trough engaging portion that permits a quick and positive locking action quite essential for devices of this kind. Trough engaging portion may accommodate flange i of different widths without requiring variation in the construction of the hanger.

The outer end of roof engaging bar 2 is preferably formed into a hook-like finger or portion having a horizontal leg 9 and a vertical leg l0. Vertical leg it is adapted to lie against a vertical face i i of the trough. Horizontal leg 9 is adapted to lie against horizontal flange l of trough 5.

In the form of the invention shown in Figs. 1 to 5, inclusive, a lug l 2 is formed by being struck out of horizontal leg 9 of trough engaging portion 3. Lug i2 is preferably bent downwardly, so that, when hook-like finger or portion comprising trough engaging part 3 is hooked over flange 7 along the outer edge of trough 5, this lug l2 will be directed downwardly and under this flange 7. Accordingly, flange T will lie between horizontal leg 9 and lug Lug i2 is then adapted to be pressed upwardly against flange '5, and if so desired, sufficient pressure may be used to crimp a portion of flange i into the cut-away portion forming an aperture IS in horizontal leg 9. The extent of crimping of flange '1 into aperture l3 will depend upon the pressure applied to lug l2 when bringing it against the under side of flange 1. The crimping action is illustrated at i i in Fig. 5. it may represent a hump or rise in flange 1, resting in aperture i3 with lug l2 pressing thereagainst from the under side so as to hold hump M in aperture l3 and securely look the hanger to the trough along the outer edge. Hence, trough 5 is carried in trough supporting relation by the hanger only along the outer edge and in a very simple manner, so that a positive locking action is obtained and the workman is required only to hook the outer end 3 of the hanger over the outer edge of the trough and press against lock [2 to form the crimped portion 14, this being done in a single operation.

Trough engaging bar 2 may extend from the roof in different Ways without departing from the scope of the present invention. Likewise, trough engaging portions 3 may join the roof engaging bar 2 in different ways from that illustrated. However, as a preferred form it is desirable to provide a bend [5 so that moisture may drain into trough 5 without running beyond the outer edge of the trough.

In the alternative embodiment of the invention illustrated in Fig. 6, aperture [3 is eliminated in horizontal leg 9 of trough engaging portion 3. Lug I2 is formed, however, out of the ofiset bent portion I5, it being noted that an aperture I6 is thereby formed which also may be used as a drain for moisture draining downwardly along roof engaging bar 2. In this form of the invention, the crimping action that is obtained in the form shown in Figs. 1 to 5, inclusive, is eliminated but a very secure and tight connection may be obtained by pressing lug l2 tightly against flange 1 so that this flange 1 is gripped between this lug I2 and horizontal leg 9. Leg l0 acts to keep these parts in secure relation so that trough engaging portion 3 of the hanger will not be readily disengaged from the trough.

In the embodiment of the invention in Fig. 7, two lugs I! are formed, instead of a single lug [2. These lugs ll may be formed out of the bent portion l5, if so desired. The alternative embodiment of the invention shown in this Fig. 7, and also in Fig. 6, provides trough hangers that may be quickly attached to the outer edge of the trough and secure a positive locking action between the trough and the hanger, with or without the lugs 12 and 11.

Without further elaboration, the foregoing will so fully explain the gist of my invention that others, by applying current knowledge, may readily adopt the same for use under varying conditions of service, without eliminating certain features which may properly be said to constitute the essential items of novelty involved, which items are intended to be defined and secured to me by the following claims.

I claim:

1. A device for hanging troughs or the like comprising a bar adapted to extend outwardly from a roof and across the open face of a trough, horizontal and vertical legs formed at the outer end of said bar, and a lug struck out of said horizontal leg adapted to cooperate with said vertical leg to secure a horizontal trough flange therebetween.

2. A device for hanging troughs or the like comprising a bar adapted to extend outwardly from a roof and across the open face of a trough, horizontal and vertical legs formed at the outer end of said bar, and a lug struck out of said horizcntal leg, said horizontal leg having an opening therein resulting from said formation of said lug, said lug being adapted to cooperate with said vertical leg to secure a horizontal trough flange th rebetween and to crimp a portion of the trough flange in said opening.
