UNITED TATES PATENT OFFICE.
SCAFFOLD-SUPPORTING DEVICE.
Application filed December 12, 1927, Serial No. 239,582, and in Canada August 4, 1927.
This invention relates to a scaffold support ing device. Its object is to provide a simple, cheap and handy method of quickly and effectively securing horizontal members of scaffolding against the walls of buildings, particularly such as are chiefly of wood construction.
The invention resides in the adaptation of a channelled or trough-like device secured vertically against a building,-which device is so cut and shaped at its lower end that it provides an efiective bearing for the edge of a timber or board to rest upon, the said board being inserted into the channel or vertical trough and secured therethrough by nails.
After the device has functioned in one position it may be quickly released by freeing the outward end of the horizontal scaffold board and lifting the same off the securing nails, and when free and in convenient position to handle easily, the transverse nails securing the device to the scaffold members can readily be released.
The device is fully shown in the drawings herewith forming a part of this application and in which:
Fig. 1 is a side elevation.
Fig. 2 is an edge view, and
Fig. 3, an end View.
From these drawings it will be noted that the device is of the nature of a rectangular trough or channel used in the vertical position and made preferably from flat galvanized sheet iron of suitable substantial thickness.
One of the sides of an open-ended trough is indicated at 4 and the other corresponding side by 5. Both the sides are cut at the rectangular recess or offset 6 which is made by an incision through the bottom of the trough at 7, and through about one-third of each of the sides to 8. The severed portion is then pressed bagkwards into a U-shaped loop as shown at y i The top edge 10 of the U-shaped loop forms a supporting ledge for a scaffold member placed edgewise vertically within the trough 11, that is to say, between the sides 4 and 5 and when so placed in position is nailed through at the nail apertures 12 and 13.
Before the aforesaid scaffold member is positioned and secured in the device, the latter is secured to the sides of the building under construction by hanging the same on to nails registering with the nail apertures 14:.
It will thus be seen that the device forms a handy and simple method for securing the ends of horizontal scaffold members to the sides of a building with absolute safety and at less cost and greater speed than is usual wilth current methods efiecting the same resu t.
Having now fully described my invention, what I claim and desire to be protected in by Letters Patent, is:
A supporting device for scaffolding comprising, an open-ended channelled member of sheet metal, a rectangular offset forming an open recess at one end of said member, said offset being effected by an incision right-angularly through the bottom of said channelled member and extending approximately onethird of the way through the sides of said member whereby the severed portion may be pressed backwards from the bottom of the said channel and folded inwardly of the sides thereof to form a U-shaped loop and thus adapted to form a web across said member intermediate of the depth of its sides and parallel to the bottom of said channel, nail apertures in the bottom of said channel, and nail apertures in the sides thereof.
In testimony whereof I afiix my signature.
JOHN A. MACDONALD.
