Application April 28, 1931. Serial No. 533,550

2 Claims.

The invention relates to a scafford support or snowhook.

The primary object of the invention is the provision of an article of this character, wherein the construction of the same is novel in form so that it may be used either as a scaiord support or snow hook and is capable of application to a roof with dispatch.

Another object of the invention is the provision of an article of this character, wherein the snow hook end thereof constitutes a loop for receiving a scaffolding piece, and such article includes a pair of legs which are adaptable for engaging the roofing nails or other fasteners, so that a strong and positive anchorage will be had.

A further object of the invention is the provision of an article of this character, wherein the legs of the same can be adjusted so that they may be spread apart or closed together in the application of the article to a roof for use either as a scaffold support or snow hook.

A still further object of the invention is the provision of an article of this character, which is extremely simple in construction, thoroughly reliable and eicient in its purposes, strong, durable, readily and easily applied to a roofing" or removed therefrom, and inexpensive to manufacture and install.

With these and other objects in view the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing which shows the preferred embodiment of the invention, and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a fragmentary plan view of a roof showing the article constructed in accordance with the invention applied both as a snow hook and a scaffold support.

Figure 2 is a plan view of the article removed and its legs spread apart.

Figure 3 is a side elevation.

Figure 4 is a sectional view on the line 4--4 of Figure 3.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail the article A which constitutes both a snow hook and scaffold support comprises a pair of legs 5 and 6, the latter being of slightly less length than the leg 5, which has one end at the corner portions thereof turned upwardly to provide spaced parallel ears 7, these serving as a hand grip for the leg 5 which is the lowermost on the application of the device to a roof while the end of the leg 6, next to said ears 7, is bent on itself to provide a closed loop 8, in which is received a scaffold piece B.

The legs 5 and 6 are swingingly connected together by a pivot 9 so that said legs can be brought into alignment with each other or spread apart in crossed relation to each other.

The loop 8 is reinforced through the medium of a brace l0 riveted thereto and to the leg 6 as is clearly shown in Figures 2 and 3 of the drawing.

The leg 5 has struck therefrom a latching lug or projection 1l which is adapted to engage in a hole 12 formed in the leg 6 so that when the legs are brought into alignment with each other they will become latched together as is clearly shown in Figure 4 of the drawing.

The legs 5 and 6 in the end portions 13 of the same at their outer side edges are provided with diagonal slots or notches 14, these converging in the direction of the pivot 9, so that said ends 13 can be engaged with a roofing nail or nails 15 for the roof plates or shingles 16, according to the fashion of the several applications of the article as illustrated in Figure 1 of the drawing.

When the loop 8 is not occupied by a piece of scaffold it serves as a snow hook to prevent snow from sliding from a roof. 'I'he legs 5 and 6 when spread apart will present dual hooks for holding snow upon the roof against sliding therefrom. The disposition of the notches 14 in the respective portions 13 of the legs enables a secure hanging of the device upon the roofing nails for the roof plates or shingles, either when the device has the legs spread apart in their crossed position or when the legs are brought together in alignment with each other, whereby the device will be latched and prevented from becoming ac* cidentally released.

What is claimed is:

1. An article of the kind described, comprising a pair of flat bars, a loop at one end of one bar, said bars having reverse angularly disposed notches, eachvopening through one longer edge of the bar, and a pivot joining the bars together for relative swinging movements with respect to each other.

2. An article of the kind described, comprising a pair of diagonally notched bars, one superposed relative to the other, a loop carried by one of the bars, means for bracing the loop, and pivot means connecting the bars together.
