Application filed May 28, 19%.

To all whom it may concern:

Be it known that we, CHARLES W. RYAN and CLARENCE M. SNYDER, citizens of the United States, residing at Anamosa, in the county of Jones and State of Iowa, have invented new and useful Improvements in Roof Brackets, of which the following is a specification.

This invention contemplates the provision of a roof bracket, for supporting planks used by workmen, and designed to be quickly and conveniently adjusted as the occasion may require, and also susceptible of use in supporting ladders on the roof for upright work.

Another object of the invention resides in providing a bracket of the above mentioned character which can be quickly and conveniently attached to the roof or removed therefrom when desired, and the parts subsequently folded to roduce a comparatively small compact artic e.

The nature and advantages of the invention will he better understood when thefollowing detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, wherein:

Figure 1 is a view showing a fragmentary portion of a root with the bracket positioned thereon for the support of a plank.

Figure 2 is a view taken at a right angle to Figure 1.

Figure 3 is a view of the bracket removed from the roor' and folded.

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

Figure 5 is a view showing the manner of using the brackets in conjunction with ladders for upright work.

Referring to the drawings in detail, 10 represents the bottom or base of the bracket which is of elongated contour, and constructed from metal or other suitable material. Supported upon the base 10 is an iron strip 11 which has one end ofiset and spaced above the base as at 12. Both ends of this strip 11 terminate to provide loops 13, which constitute hearings for the plank support and the brace therefore indicated at 14 and 15 respectively. The plank support is substantially U-shaped member, the parallel Serial H0. 641,000.

limbs of which are connected by means of a pivot bolt 16' which passes through one of the bearing loops just referred to, while these limbs are further secured together by a cross bar 17 arranged in close proximity to the closed end of the support as illustrated. This cross bar 17 is adapted to be received by any pair of notches 18 formed in the parallel limbs 01': the brace 15, the latter being pivotally associated with the other end of the iron bar 11. Manifestly, the plank support 1d and the brace 15 can be independently swung upon their pivots toward and away from each other, and the bar 17 arranged in any pair of notches so that the plank supported by the support 14: can be arranged in the most convenient position for use.

In practice, the base 10 has one end inserted under the butt of one shingle on the root indicated at A, while the pointed prongs 19 secured to the underside of the base and adj acent the opposite end thereof engage another shingle on the roof to hold the base immovable thereon. The ofiset end 12 of the iron bar 11 which is spaced from the base 10 rises upon the upper surface of the shingle beneath. which the end of the base is inserted, and this bar is clamped upon this particular shingle by the weight of the plank supported by the support 1d. Consequently, the bracket is fixed immovably upon the roof when the plank is arranged upon the support 14, and there is no possibility of the bracket being accidentally separated there from under any circumstances.

The bracket can also be used for supporting a ladder fiat upon a roof which is accomplished by arranging one rung of the ladder herein indicated at 20 between the support 141 and the brace 15 therefore, and subsequently locking these parts together in the manner shown and described. By using two brackets, the ladder can be supported for upright work as shown in Figure 5.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, we desire to have it understood that we do not limit ourselves to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.

Having thus described the invention, we claim:

A roof bracket comprising a base plate meaees of the strip whereby the latter is held in clamping relation with the shingle under the weight of the object arranged on said support, and a pivoted bracing element carried by the opposite end of the strip and designed to engage said support to hold the latter fixed with relation to the base in any given position.

in testimony whereof we aflix our signatures.

CHARLES W. RYAN. CLARENCE M. SNYDER.
