SI-IiN'GLING-BRACKET;

Specification of Lettcrs Patent.

Patented Apr. 8, 1919.

Application filed March 2, 1918. Serial no. 220,068.

To all whom it may concern:

Be it known that I, ALPHA citizen of the United States, residing at West Barrington, in the county of Strafford and State of New Hampshire, have invented new and useful Improvements in Shingling-Brackets, of which the following is a specification.

This invention relates to scaffolds, and more especially to shingling brackets; and the object of the same is to produce a light, simple, inexpensive,'and reliable structure of this kind which may be stored in small compass when not in use and which may be used on roofs of a variety of pitch, for holding the staging boards while shingles and the like are being applied or perhaps while the chimney is being built or repaired.

This object is carried out by constructing the bracket in the manner hereinafter more fully described and claimed, and as shown in the drawings wherein Figure 1 is a perspective view of a portion of a roof with this improved bracket placed thereon, the staging board being indicated in dotted lines.

Fig. 2 is a longitudinal sectional view through the device on a much steeper roof, showing how the spur at the lower end of the brace enters the roofing boards when the bracket is used in this instance.

Fig. 3 is an enlarged perspective detail of the lower end of the brace.

In the drawings I have used the letter R to designate the roof, upon which in Fig. 1 is shown already laid the lower course of shingles S, above which the roof is as yet only the boards to which the shingles are to be nailed. I speak of shingles, but of course these elements might be slates, in which case'there would have tobe boards laid upon the courses of slates where the spurs referred to hereinafter occur, and these boards in that instance would have to be suitably supported. However, my bracket is particularly intended for shingles, although I do not wish to be limited to its use. The bracket is composed of four parallel bars, whereof thosenumbered 1 and 2 may be called the side bars, and those numbered 3 and 4 the intermediate or central bars. The latter are disposed rather closely together, and the side bars are spaced therefrom quite a little distance as shown; and transverse rungs 5 connect all bars, there being of necessity one rung at the top, a

number at the bottom, and possibly intermediate rungs throughout the entire length of the structure as seen in Fig. 1. Inserted into and depending fromthe lower faces of the outside bars, and

lower extremities as shown, are spurs 6 of metal and of a proper size and length to stick into the roof boards or the lower course of shingles and support the entire bracket upon the roof as shown in the drawings. I use these spurs in the side bars rather than in the intermediate bars, because the side bars are spaced apart the full width of the bracket, and therefore when the latter is held by two of these spurs firmly engaging the roof or the lower course of shingles, it will not swing from side to side. To an extent Fig. 2 is a modification, in that this view shows additional spurs 7 depending from the lower faces of the side bars at their upper ends, but these I do not always contemplate using. Or, if I use the upper spurs, I do not always contemplate using the lower spurs, because two sets of spurs are not ordinarily necessary.

Pivotally mounted on the upper rung at the point 10 is an arm 11 which is of a width to be folded between the innermost bars when the structure is collapsed for storage or transfer, and of a length about half that of the bars. The numeral 12 designates a brace, forked at its upper end as at 13 and pivotally mounted as at 14 on the lower end of the arm 11, this member being a little wider than the space between the innermost bars 3 and 4 so that it will overlie them when the parts are folded together, and of a length to reach a little beyond the lower ends of the bars when the parts are in this condition. The obvious purpose of the brace is to support the outer end of the arm, as seen in Figs. 1 and 2 of the drawings. Its lower end is reduced and shouldered as at 15, beyond which its extremity is continued into a narrow spur 16 which is preferably cut ofi oblique on its under side as seen at 17. This oblique face prevents the spur from embedding the roof boards or shingles when the parts stand as seen in Fig. 2, whereas the shoulder always contacts with the upper edges of the intermediate bars 3 and 4. When, however, the bracket is applied to a steeper roof as seen in Fig. 2, and the brace 12 takes a different angle with respect to the bars, the tipof its spur will project between them and beyond preferably near their their lower faces and into the roof slightly, just at a time when the use of an additional spur to support the bracket on the much steeper roof is necessary and much more desirable. At this time and at all times the shoulders 15 rest on the bars 3 and 4 while the projection or extension 16 rests on one of the lower rungs between these-bars. The staging board S is now laid across the arm 11, and extends from onebracket to another in a manner well understood to experts in this art. When the device is not in use, the parts may be folded in an obvious manner. I donot wish to be limited to thematerials or than as herein set forth.

What is claimed-as new is The herein described shingling bracket comprising ,four parallel bars whereof the proportionsof parts, nor to details other" innermost are disposed more closely together than the others, a series of transverse rungs extending through all bars, spurs depending 'from the lower faces of the outermost bars, an arm pivoted at its upper end on the uppermost rung, a brace forked at its upper end and passing astrideand pivoted to the lower end of the arm, and a reduced extension at the lower end of said brace producing shoulders to bear on the facesof the intermediate bars and a spur at its extremity of a length to project below the lower faces of. said bars when the brace standsat a considerable angle thereto,- and undercut so as not to project below said faces at othertimes. I

In testimony whereof I aflix my signature.

ALPHA D. TUTTLE.
