SCAFFOLD BRACKET Filed June 23, 1959 INVENTOR. I. G Ra mbo,

Beatty, Wanwatosa, Wis., assignors to Safway Steel scaffolds Co. of Wisconsin, Wauwatosa, Wis., a corporation of Wisconsin Application June 23, 1939, Serial No. 280,780 2 Claims. (01-. 248-235) This invention relates to brackets, and more particularly to a bracket adapted for use on scaffolds.
In order to make a scaffold rigid it is the usual practice to have a rectangular framework with members in a vertical plane on all four sides. Such construction, while satisfactory to workers on top of the scaffold, is extremely awkward to a person working below the top of the scafiold.
One object of the present invention is, therefore, to devise a structure which will support scaffold planking on the exterior of a rectangular tower scaffold to enable workers to work free of encumbrances such as the scaffold bracing.
Another object of the present invention is to produce a removable bracket for use on the ends of a sectional scaffold which may be applied on either side thereof.
A further object is to provide'a bracket which will support planking securely on the exterior of the end of the scaffold.
A further object is to produce a bracket which may be attached to a scaffold at various elevations thereon.
Further objects are to provide a bracket which will be strong and rigid, which will be economical to manufacture and which may applied and removed.
Other objects will be apparent from the following description.
According to the present invention a bracket is provided with an attaching gusset bent back be readily to form a hook engageable over a horizontal scafiold member, said bracket being provided with a lower support extended on both sides of 2 the bracket to engage a post which may be offset on either side of the bracket.
In the drawing:
Fig. 1 is a prospective view of a sectional scaffold showing the bracket forming the subject matter of the present invention attached thereto;
Fig. 2 is a side elevational view of the bracket applied to the scaffold;
Fig. 3 is a rear view of the bracket as seen from the right in Fig. 2; and
Fig. 4 is a cross-section on the line 4-4 of Fig. 2.
Referring to the drawing in which like parts are designated by like numerals throughout the several views, the scaffold comprises a pair of end frames ill-i0 held in spaced vertical posi-- tion by a pair of cross braces "-4 l'.' The end frames and cross bracesform a unit upon which other units may be superposed with coupling pins l2 joining the adjacent ends of theend frames.
Each end frame comprises a pair of vertical posts l3- -i3 joinedadjacent the upper portions thereof by a horizontal support l5 and joined intermediate the ends by a second horizontal support IS with suitable shear braces Il-ll connecting the supports to form a rigid structure. All parts of the scaffold end frame are preferably welded together to form an integral unit.
The bracket forming the subject matter of the present invention is shown applied to the scaffold, in Fig. 1, and is shown in detail in Figs. 2, 3 and .4.
Referring particularly to Figs. 2, 3 and 4 the bracket is made with a horizontal supporting member 20 which has a turned up toe 2| on the outer end and is joined to a vertical member and diagonal member 22 and 23, respectively,
to form a triangular bracket. The upper end of the bracket is provided with a plate l9 which is welded to the vertical member 22 and is bent back to form a hook 24 engageable over the horizontal support IE or ii.
As will be seen in Figs. 1, 3 and 4, when the hook is engaged over the horizontal support 15 or is the plane of the bracket, is spaced from the post IS. A guiding support 25 is therefore provided at the lower end of the bracket and is extended on both sides of the bracket and provided with an enveloping guard 26 on each end thereof. The guiding support envelopes the post I between the guards -26. Suitable braces 28 may be welded 'to the diagonal 23 of the bracket and to the support 25 to stiffen the support 25 and prevent failure of the bracket.
It will be noted that by having the guiding support extend outwardly on both sides of the bracket the samebracket can be used interchangeably on either side of the scaffold end frame.
Having thus described the invention it will be noted that it is readily susceptible to changes and modifications and it is not therefore desired to limit the invention to the precise form herein shown and described but only by the plate attached to said frame and extending on,
both sides thereof, a hooked end on said plate engaieable over said support to support said fram in a plane substantially perpendicular to said support and spaced from saidpost, and a guiding support attached tothe lower end of said frame and extending to one side thereof 2 l ammo? spaced from one of said posts, and a guiding support attached to the lower end or said frame and extending on both sides or said frame to engage an ofl'set post on either side or said 5 frame to support the lower end of the frame.
