Specification of Letters Patent.

Patented Apr. 22. 19 19 Application filed July 13, 1918. Serial No. 244,784.

roof bracket, and particularly to so design the bracket that it may be used for supporting scaffolds on roofs which are being shingled with prepared or slate shingles, as it will not injure the shingles that it comes in contact with.

A further object is to provide a roof bracket including a supporting frame having a rotatable split haft, the roof bracket being connected to the roof by means of a strip of metal having one end attached to the roof boards and the other end slipped through the slit of the shaft and wound upon the shaft so that the metal strip may remain in place after the bracket is removed and may be bent back under the shingle that covers it so that it will be out of sight, this construction permitting the straightening out of the strip at any time and its re attachment to the bracket.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a perspective view of a roof showing my improved scaffold bracket attached thereto, the beam 13 being partly broken away;

Fig. 2 is a face view of the bracket; and

Fig. 3 is a side elevation thereof, the strip 18 being in section.

Referring to the drawings, it will be seen that my improved roof bracket consists of a frame formed of iron rod, bent to provide the parallel legs 10 having eyes 11 at their ends, and further bent to provide the upwardly and then inwardly extending hook portion 12, designed to receive a scaffold beam or joist 13. Rotatably disposed in the eyes 11 is a shaft 14c which is longitudinally split. This shaft at one end is formed with an eye 15 and after the shaft has been inserted in the eyes 11, the extremity of the shaft remote from the eye 15 may be expanded so as to hold the shaft in place against accidental detachment.

For the purpose of rotating this winding shaft 14; and holding it in rotated position, I provide a handle 16 which at one end is bent to form a hook engaging through. the

eye 15 and at its opposite end is bent to form a laterally extending hook 17 which engages with the adjacent leg 10.

Coacting with the split shaft and acting as a support for the bracket is a strip of metal, as for instance tin, designated 18. One end of this strip is designed to be attached to a roof bracket and the other end of the strip inserted in the split shaft. Then the shaft is rotated to wind up the strip two turns on the shaft, the shaft being held from reverse rotation by engaging the hooked end 17 of the handle over the leg 10. This strip may be of any suitable length but is preferably about eight inches long and two inches wide.

In the actual use of this invention, in shingling roofs, the thin metal strip 18 is nailed to a roof board. The other end is then inserted in the spli shaft and the shaft given a few turns by means of the lever or handle 16. The hooked end of the lever is then brought over the leg 10 as before stated and locked in place by means of the beam or joist 13, which is inserted in the hook 152 of the bracket. In actual practice, it has been found that by fastening one end of the thin metal strip 18 to the roof board with four or five shingle nails and then winding the other end around the shaft, as

described and locking the lever or handle 9 16, it is impossible to put enough pressure on the timber to tear away the strip 18 from the roof.

This bracket is especially adapted to fastening scaffolds to roofs that are being shingled with prepared or slate shingles, as it will not in the least injure the shingles with which it comes in contact. Furthermore, when the bracket is detached by removing the 2 by 4 timber and reversely rotating the shaft, the metal strip 18 remains in place,

covered by the shingle disposed over it, and

the projecting end of the metal strip may then be bent back under the shingle and this end Will be o t of sight. If at any time it is desired to replace the scaffold, the end of the strip of metal may be readily bent back again so as to project beyond the shingle and may be readily attached to the shaft and Wound thereon, as before. Of course any number of these brackets may be used along a roof, depending upon the weight designed to be supported on the bracket.

I claim 1. A roof bracket comprising a hookshaped frame, a split shaft rotatably mounted in the frame and having means whereby it may be rotated and locked from reverse rotation, the shaft being split to receive the extremity of a metallic supporting strip.

2. A roof bracket comprising a hookshaped frame having eyes at its extremity, a split shaft rotatably mounted in the frame and having means whereby it may be rotated and locked from rotation, and a metallic strip attachable to a roof board and having one end inserted through the shaft and adapted to be wound thereon.

3. A roof bracket comprising a frame formed of a single length of metallic rod bent to provide parallel legs and a hookshaped portion, the legs at one end being formed with eyes, a split shaft passing through said eyes and rotatable therein, a handle engaged with the shaft and having a laterally extending hook adapted to engage over the frame, and a strip of metal adapted to be attached to a roof board and having one end inserted into the split. of a shaft and wrapped thereon by rotating the shaft.

In testimony whereof I hereunto affix my signature in the presence of two Witnesses. JOHN N. ANDERSON. l/Vitnesses:

RUTH E. SoHANTz, HERBERT S. SIceELKo.
