BRACKET.

Application filed August 4, 1927. Serial No. 210,669.

This invention relates to brackets for supporting platforms on the walls of buildings and is designed primarily for use by building contractors, painters and other mechanms.

The object is the provision of a safe and reliable supporting bracket for platforms employed by persons in dangerous tasks, such as the erection of a building, the painting thereof and etc., and wherein the brackets may be easily and securely arranged upon a wall structure, braced in an effective manner to firmly support a platform thereon, and provided with means for arranging a frame or guard rail which surrounds the platform so that the mechanics, occupying the platform will be safeguarded against accidental precipitation therefrom.

A further object is the provision of a bracket support for platforms that is of a collapsible and foldable nature, light in weight so that the same can be easily conveyed, readily set up,etfectively supported upon a wall structure and provided with simple but effective means for preventing the sliding of the boards that constitute the platform thereon, together with a uard rail that surrounds the scaffold beani and an upright or ledge between the scaffold boards and the guard rail for preventing the mechanics tools or appliances from being accidentally moved off of the platform.

Other objects and advantages will become apparent during the course of the invention, illustrated by way of example in the accompanying drawings. I

In the drawings: v

Figure 1 is a transverse sectional view through a platform supported in accordance with this invention.

Figure 2 is a top plan view of one of the brackets the platform boards being omitted.

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

Figure 4 is a sectional view approximately on the line 4.-4 of Figure 1.

Figure 5 is an elevation, with parts in section, showing the bracket collapsed.

Figure 6 is a sectional view on the line 6-6 of Figure 5.

Figure 7 is an end view to illustrate the manner in which the platform is supported on two of the brackets.

The brackets constituting the improvement are preferably constructed of angle irons and include a frame-like member which I will term the back A, another frame-like member which I will refer to as the support B and a frame-like brace C between the back A and the support B.

The back A, of each of the brackets, as stated, IS in the nature of a rectangular frame, the same including parallel sides 1, connected at suitable intervals by transverse plates 2. The inner flanges of the angle sides 1 are provided with key-hole slots 3, and the connectmg plates 2 are provided with openings for the reception of screws 4 which are let in the wall 5 of a building. Other headed screws are also let in the wall prior to the insertion of the screws 4 and these screws are received in the restricted passages of the key-hole slots 3. The heads of the screws contact with the outer walls of the elements constituting the back A for effectively sustaming the back in an upright position in the wall 5.

The rectangular frame comprising the support B has its side parallel members 6 pivotally secured to the side members of the back A, preferably through the medium of a rod 7 The sides, at their upper edges are connected by transverse plates 8, and the sand frame, ad acent to its outer end is either formed with or has let therethrough substantially rectangular socket members 9 for a purpose which will presently be apparent. The brace C has its parallel sides pivotally secured, as at 10, to the side members of the support B and the opposite ends of the said side members are pivoted to the sides of the back 1 through the medium of a removable rod 11 which has one of its ends headed and its opposite end threaded. Screwed on the threaded end of the pivot rod 11 there is a nut member 12. The side members 12'; of the brace C are connected by transverse plates 14.

When the brackets are not in use the pivot 11 is removed, and the back A is swung under the supporting frame B, and thereafter the brace C is swung against the folded back A. This arrangement is illustrated in F igures 5 and 6 of the drawings and when the bracket is collapsed it presents a small comdesigned to be arranged over the boards 19 that provide the platform, which, of course, rests on the support portion B of the brackets. Received in the sockets of the brace members of the brackets there are the lower ends of uprights 20. Passing through suitable enings in the socket members and throug the uprights 20 there are cotter pins 21 which effectively hold theuprights in the sockets. Contacting with the inner faces of the uprights 20 and also contacting with the outer board of.the platform 19 there is a vertically arranged longitudinally extending board 22 that provides a ledge plate to prevent the tools or other accessories of the mechanics employing the platform from being accidentally precipitated therefrom. The uprights 20 are connected by upper boards or plates 23 and by end plates 24, the last mentioned plates being directed toward the building and preferably having short lateral plates 25 secured to the ends thereof, and these plates 25 may be temporarily fastened to the wall 5. These connected plates and uprights provide a protective rail for the usersof the platform.

The improvement may be constructed of wood, steel, aluminum, or in fact any metal having sufficient strength to insure safety in the use of the device. The device may, of course, be constructed in various sizes and I do not wish to be restricted to the precise shape of the construction as disclosed by the drawings and set forth in the specification.

In this connection it may be well to state that I also do not wish to be restricted to the precise details of the construction as herein set forth and, therefore, hold m selt entitled to make all such changes there rom as fairly fall within the scope of what I claim.

Having described claim A bracket for supporting platform boards includin a horizontal support member, a vertical back member adapted to be adjustably fixed on the face of a building or the like and a brace member between the supo rt and back member, all of said members emg pivotally connected and one of the pivots being removable to permit of the members being folded against each other, the support member having spaced depending socket portions at the outer end thereof designed for the reception of uprights for a protective rail for the platform boards, means passing through the sockets for sustaining the uprights therein, a flexible element loosely connected to one end of the support member designed to be arran ed over the boards and means for adjustaily securing the flexible element to the second end of the support member for holding said flexible element in tight engagement with the the boards.

In testimony whereof I afiix my signature.
