UNITED STATES PATENT OFFICE.

GEORGE F. MOORE, OF GARMAN, ILLINOIS.

SCAFFOLD-BRACKET.

Application filed May 18, 1917.

To all whom it may concern Be it known that I, GEORGE F. Moons, a citizen of the United States, residing at Carman, in the county ofHenderson and State of Illinois have invented certain new and useful Improvements in Scaffold-Brackets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in scaffold brackets and the principal object of the invention is to provide a foldable scaffold bracket which is adapted to be removably attached to a wall in such a manner as to support a scaffold.

Another object of the invention is to provide a strong, durable and readily constructed device which may be easily and cheaply manufactured.

\Vith these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which Figure 1 is a side view in elevation of a scaffold bracket constructed in accordance with this invention, showing the same attached to a wall;

Fig. 2 is a detail perspective view of the bracket;

Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 2.

Fig. 1 is a side elevation of the bracket collapsed.

Referring to the drawing, 1 designates the horizontal supporting element of the bracket which comprises a pair of angle irons 2 having their vertical flanges arranged in spaced parallel relation. The horizontal flanges are positioned at the upper edges of the vertical flanges. and welded or otherwise secured to the angle members at one end is a suitable transverse attaching member 3 having its end outturned to form a hook 4. This hook is adapted to extend through an aperture formed in the wall of the building or sheathing and the hook 4 extends upwardly as illustrated in Fig. l in order to support the device in place.

Pivoted as at 5 between the vertical flanges of the angle members 2 at the ends on which the attaching element 3 is formed,

Specification of Letters Patent.

Serial No. 169,472.

is a suitable enlarged head 6 which is formed at the upper end of the vertical leg 7 of the bracket. The upper edge of the enlarged head 6 when the leg is in vertical position is adapted to engage the under side of the attaching element 3 in order to limit the rearward movement of the leg. The lower end of the leg is provided with an aperture for the reception of a pin 8 by which the bracket arm which will be more fully hereinafter described, is attached to the vertical leg. Riveted or otherwise secured to the leg 7 adjacent its upper end is the cross element designated generally by the numeral 9 which comprises a strip of strap iron 10 bent back upon itself as at 11, and the bent back portions are provided at their ends with outturned ears 12 which are riveted or otherwise attached as at 13 to the leg.

Pivotally mounted as at lat between the vertical flanges of the angle members 2 adjacent their outer ends is an ear 15 formed at the upper end of the supporting arm 16 which extends downwardly and inwardly and is bifurcated at its end as at 17 to receive the vertical leg 7. The bifurcated portion is formed with apertures for the reception of the pin 8 by which the lower end of the leg 16 is removably attached to the lower end of the leg 7. The pin 8 has secured thereto a chain 18 having its upper link passed through an opening 19 in the leg 7 and it will thus be seen that the pin will be secured against loss.

It will be apparent from the foregoing, that in use the device is positioned in the manner illustrated in Fig. 1 by inserting the hook through a crack or aperture in the sheathing or side of a wall and swinging the outer end of the horizontal support into the position illustrated in the drawing. The lower end of the arm 16 is then swung inwardly so as to cause the lower end of the leg 7 to be received in the bifurcation 17 and the pin 8 is then passed through the alined openings of the bifurcation of the arm, thus rigidly securing the arms together and supporting the horizontal support in proper position. The scaffold board may then be placed in position and it will be apparent that any possibility of the bracket moving laterally is prevented by the cross member 9 and the scaffold will be firmly held in place.

When it is desired to fold the bracket.

the leg 7 is swung upwardly in parallel relation to the supporting element 1 and the bracing rod 16 subsequently swung beneath the rod 7.

While in the foregoing there has been shown and described the preferred embodiment' of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as Will fall Within the spirit and scope of the appended claim.

What is claimed is A folding scafiold bracket including a horizontal supporting member comprising a pair of parallel angle bars, a transverse strip connecting the rear end portions of the angle bars and adapted for retaining the same in spaced relation, said transverse strip being provided with an upwardly extending anchoring hook, a vertically disposed supporting member having its upper end portion enlarged and pivoted between said angle bars and engaging said transverse strip for limiting the rearward movement of the vertical supporting member, and an angularly disposed bracing member pivoted to said horizontal member and detachably engaged with the vertical supporting member. In testimony whereof I aflix my signature in presence of two witnesses.
