To all whom t may concern.'

Be it known that I, EDMUND A. SCHADE, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Roof-Brackets, of which the following is a full, clear, and eXact description.

This inventionis concerned with an improved form of bracket for supporting oards, shelving or platforms upon slanting roofs, thereby being instrumental in forming a staging on the roof, this staging being used by the workmen in building or repairing as well as a support for other purposes.

Preferable embodiments of my improve ment are illustrated in the accompanying drawings, in which,-

Figure 1 is a perspective view of a preferred form of my bracket in position on a roof. Fig; 2 is a longitudinal vertical section through the bracket shown in Fig. l. Fig. 3 is afragmentary perspective View of the bracket. Fig. 4 is a horizontal section on the line 4-4, Fig. 2. Fig. 5 is a frag mentary perspective view of 'a modified form of bracket.

Referring to the drawings in detail, A designates a roof and B shingles thereon, the bracket of the present invention being particularly adapted for use in connection with shingled roofs. The bracket of the present .invention has an outer and inner frame. The outer frame is in the form of a substantially V-shaped member, preferably of light metal strip stock, one arm l being substantially horizontal and forming the load supporting portion, the other arm 2 providing a supporting standard therefor which is arranged to extend substantially vertically. The inner end of the arm 1 is 11p-turned at 3, forming in normal position an obtuse angle-with the horizontal strip, as shown in dotted lines in Fig. 2. This upturned foot. 3 isv of a pliant material which will permit it to bend somewhat under pressure and is intended for insertion beneath the lower edge of a shingle. The lower end of the arm 2 of the bracket frame is cut away to provide gripping points or edges 4-4 for engagement with the face of a shingle. The inner frame is somewhat rectangular in shape and comprises a foot portion 5 forming one side, an end G rigidly secured to the arm 2 of the outer frame, and a vertically extending side 7 with a down-turned end 8 cut away to provide gripping points 9. The arm and the end 8 are not attached to the outer frame and Vthe gripping points are located inwardly of the foot portion 5 a sufficient distance to permit a shingle to be inserted therebetween, the end S and arm 7 yielding under pressure to provide for variation in the thickness of the shingles. The feet portions 3 and 5 in their normal positions are in parallel planes and are each adapted to be inserted beneath a roof shingle. They eX- tend however at such an angle relative to the main body of the frames that when they are so inserted beneath the lower ends of adjacent shingles, as indicated in Fig. 2, the foot portion will be bent outwardly, the material of the frame so permitting, and this action will tend to force the gripping `points 4 into the shingle so that the bracket laid across the load supporting members of the brackets, the weight of this platform pressing the grippingpoints 4 and also the gripping points 9 firmly into their respective shingles, or into the roofing, as the case may be. |The load strain tends to cause the members 2 and 7 to buckle outwardly. This is particularly true if the bar forming the platform is made of sudiciently light stock to permit the feet to bend under practical working conditions. I find, however, that by strengthening these portions against buckling, such a grade of stock may be employed to give the desired results without weakening the bracket and making it liable to buckle under load strain. I preferably so strengthen the arms or members 2 and 7 by forming the saine with corrugations 10 and 11 respectively, which are inwardly directed and which therefore will strengthen their respective bars against outward buckling. The loadsupporting portionlofthe bracket will engage the upper end of the inner frame and exert pressureV upon the down-turned end 8 thereof so as lto force the prongs 9 into the shingle. This pressure will also tend to buckle the bar 7 outwardly but this is prevented by the use or' the strengthening corrugations described.

I have also provided an improved .load supporting means including means for retaining the staging or boards on the load supporting bar 1. A preferable embodiment of this featureisshownin Fig. 3 wherein an eXtra stripor bar 12 is superposed upon the bar 1 of the bracket and is rigidly secured thereto, as by riveting, thus strengthening the bar and tending to prevent it from buckling under load strain. This bar y1Q has its ends upturned adj acentthe extremities of the frame, one end 13 lhaving' an aperture therein through which a nail or other securing device 15 may be driven into the staging@ The other end ltisupturned at an angle to form a lug substantiallyparallel ,with thebent Jr'oot 3, the space between `these two portions bein' suflicient to receive the `shingle under which the footl isrinser-ted. The lug 1l ol the bar-is provided with an aperture through which a nail or other securing device may be driven into the inclosed shingle, this nail also acting toy prevent the staging C from being accidentally removed from the bracket. The "foot 3 prevents the nail from `penetrating an underlying shingle.

A modiiied form or' load support-is shown in Fig. 5, wherein 1il designates `the load supporting bar of the outer .frame and 3a its upfturned foot. .I dispense With the super-posed bar by forming the bar 1a with an inwardly directed corrugation 17,the reb. strengthening the bar 1L v,against inwar buckling under load strain. A shortstrip ,18 Yis rigidly secured to theedge ofthe Y described.

The upper face of the upper supporting strip, whatever form of bracket is employed, is preferably pro-vided With spurs or .similar retaining means for ,engagingv the under vface `ofthe sta ging` or platfornrC, as indicated in the drawings.

Frornithe foregoing itavlll be seen-that '1 have de vlseda simple andelicient form of roofing bracket Which however is susceptible p Y `of modification -boih in form and relative arrangement of parts Within A,the scope of theappended claim. l
