SCAFFOLD SUPPORT.

' Application filed October 24, 1927. Serial Ito/228,365.

This invention relates to new and useful improvements in scaffold supports and more particularly relates to such a support of the portable type and which is constructed of metal.

7 An object of the invention is to provide an all-metal scaffold support which may be collapsed or folded into a comparatively small bundle when not in use, and, which is so constructed that it may be detachably secured to a wall or upright in comparatively short time.

A further object of the invention is to provide a scaffold support'comprising an arm having an elongated opening at one end thereof adapted to receivea tongue provided upon one end of a leg, the other end of which is provided with a tooth or prong adapted to engage the surface of the wall or upright, and the arm having a bracket secured to the opposite end thereof, wherein a plurality of slots are provided, each having an enlarged portion adapted to receive the head of a nail, and the reduced end portions of said slots being adapted to engage the body of a nail, back of'its head, to prevent the bracket from accidentally becoming disengaged from the wall, and at the same time permitting the bracket to be disengaged from the nail or nails to remove it from the wall.

Features of the invention reside in the general construction of the support, as a whole; the provision of the key slots adapted to receive ordinary nails for securing one end of the arm to a wall or upright; the connection between the arm and the leg, which permits inverting the arm; the use of the brace member having one end pivotally connected to the arm and its other end adapted to be engaged with the wall to prevent swaying of the support; the means for securing the lower end of the leg to the wall surface; and, inthe hook member provided at one end of the arm, whereby the latter may be utilized onthe surface of a roof as a supporting means for a foot rest such, for example as a two-by-four, such as is commonly used to provide a support for a workman, when shingling or surfacing a roof.

Other objects of the invention will appear from the following description and ac-- companying drawings and will be pointed out in the annexed claims. i

In the accompanying drawings there has been. disclosed a structure designed to carry out the various objects of the invention, but it is to be understood that the invention is not confined to the exact features shown as various changes may be made 'within the scope of the claims which follow.

In the accompanying drawings forming part of this specification;

111 the selected embodiment of the invention here shown, there is illustrated in Figure 1, a sectional plan view of a corner of a building, comprising the walls 2 and 3 supported by suitable uprights or s'tuddings 4,

Two different sizes of scaffold supports are preferably used in the erection of a scaffold, as shown in Figure 1. The supports used on the sides of the building each comprise an arm 5, having an elongated opening or slot 6 provided at the outer end thereof adapted to receive a tongue 7, terminally provided upon a leg 8. The opposite end of the leg 8 has a tooth or prong 9 adapted to pierce the surface of the wall or studding to secure the lower end of the brace thereto. The leg is preferably of angle iron cross-section, and one flange thereof is cut away at the lower end of the leg to form the tooth 9 and to provide an offset extension 11, adapted to engage the surface of the wall, as indicated in Figure 7. A slot 12, preferably diamond-shaped, is provided in the extension 11 to receive a nail 13 for securing the lower end of the leg 8 to the wall, to prevent it from accidentally becoming disengaged therefrom. (See Figure 7.)

The means provided for detachably securing the arm to the surface of the wall or studding is shown in Figure 4, and consists of a bracket 14 which is suitably secured to a hook 15, terminally formed on the arm 5 as shown. Diamond-shaped slots 16 are provided in the bracket 14 adapted to receive nails or similar devices for securing the bracket to the wall. The provision of the diamond-shaped slots 16 is an important feature ofthis invention, in that they provide means whereby the bracket may be quickly removed from the wall without the necessity of having to remove or withdraw any nails from the wall. The central enlarged portion of each slot is of suflicient size to permit the head of the nail to pass therethrough, while the upper ends of the slots function to prevent the heads of the nails from passing through the slots, when the arm 5' is secured to, a wall, as shown in Figure 2. Asimilar shaped slot 17 is pro- Vided at the outer end of the arm 5 as shown in Figure 5.

A brace member 18 has one end pivotally connected to the arm 5 intermediately thereof. The opposite end 19 of the brace member is off-set and apertured to receive a nail 21 for securing that end of the member 18 to the wall. This brace member functions to prevent the arm and leg from swaying, when in operative position, as shown in Figures 1 and 2.

In order to provide a suitable support for the boards or planks 22, indicated in dotted lines in Figure 1, the arm 23 of the corner supportis preferably longer than the arm 5, previously described. The necessity of this will readily be understood by reference to Figure 1. Each arm 23 is likewise provided at its inner end with a hook member 24, having an angled bracket 25 secured thereto, the ends of which are provided with diamond shaped slots 26, as shown in Figure 3. These slots are arranged transversely of the ends of the bracket 25 so that the restricted or reduced end portions thereof will be substantially vertically alined. lVhen nails are inserted in the slots and driven into the surface of the building wall, the bracket 25 will be prevented from accidentally becoming detached from the wall as a result of the nail.- heads being too large to pass through the reduced ends of the slots. To remove the bracket from the nails, it is only necessary to lift the bracket upwardly a distance sufficient to allow the heads of the nails to pass through the enlarged central portions of the slots. To remove the corner bracket 25 from the corner of a building, when positioned thereon, as shown in Figure 1,'it may be necessary to slightly bend the nails before the brackets can be disconnected therefrom, as a result of the nails being driven in at right angles to each other. This, however, is not-always necessary.

The outer end of each arm 23 is provided with an up-turned lug 27 which functions as a guide or stop to prevent the outer planks or boards from slipping off the support. A leg 28 having an off-set lug 29 terminally provided thereon, provides means forbracing the arm 23. The lug 29 is adapted to be receivcdin a slot 31 provided in the vertical flange 32 of the arm 23. The lug 29, is suit ably apertured to receive a nail 33 or other suitable device to prevent the arm from accidentally becoming disengaged from the upper end of the leg 28, when the arm and leg are connected together as shown in Figures 3, 9, and 10. The lower nd of the leg 28 is also provided with a tooth or prong 34, adapted to engage theside wall or studding, An off-set extension 35 is also provided at the lower end of the leg 28, having an aperture therein adapted to receive a nail 36 for securing the latter to the wall.

From the foregoing, it will readily be seen that this novel scaffold supportis well adapted for use to support scaffolds such as, are commonly employed in the construction of buildings. By means of the diamondshaped slots 16, which, by the way, function in a manner similar to an ordinary key slot,

the arms 5 and 23 may be quickly removed or detached from the wall, when it is desired to take down thescaffolding. As before stated, the slots 16 permit the arms to be removed from the wall without the necessity of removing the nails therefrom. After the arms have thus been detached from the nails, the latter may be driven into the wall.

An important feature of the structure also resides in the invertibility of the arm 5. This has been found of particular advantage when, for instance, the arm is secured to the wall adjacent to a window or door opening, as shown in the upper portion of Figure 2. WVhen thus positioned and the arm is in an uprightposition as shown in Figures 2 and 41-, should the inner end 19 of the brace mem-' ber 18 happen to fall in the window or door opening, then the arm 5 may be inverted, as shown in Figure 1, thereby causing the brace member 18 to assume a positionon the opposite side of the arm. The arm 5 may be IOU secured to the wall by means of the diamondshaped slots 16 being engaged with nails driven into the wall as shown in Figure 2.

The supporting arms 5 are also adapted for use to support the usual two-by-four or foot rest 37 used when shingling or re-surfacing a roof, as shown in Figure 11. W hen thus used, the brace member 18 is folded against the arm 5 and the two-by-four 37 is engaged with the hook 15 provided at one end of the arm. The opposite end of the arm is detachably secured to the roofing boards 38 by means of a nail 39 inserted in the key slot 17 shown in Figure 5. The key slot 17 permits the arm 5 to be detached from the nail 39 by simply moving the arm upwardly sufficiently to permit the nail head to pass through the enlarged central portion of the slot.
