STAGING Filed May 24, 1-938 2 Sheets-Sheet 2 Patented Nov. 1, 1938 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to a form of staging which is primarily designed for use by painters while painting the sides of a building, but which is adapted for use for other purposes.

In Massachusetts, and possibly other States, strict laws are in force as the use of stagings and strict inspection is required before permits to use are granted, the use of certain types of suspended stagings being prohibited. Stagings which are built up from the ground are permitted but are usually expensive.

The objects of my invention are to provide a form. of staging which may be easily erected, is rigidly supported on the ground without in any way being attached to the building in connection with which it is used, which is readily adjustable in height within the limits of an ordinary dwelling house, which is comparatively inexpensive to construct, which provides a rigid and perfectly safe support for men who may work on it, and which will pass inspection so that its use will be permitted under the law.

I accomplish these objects by providing a pair of right angular shaped brackets, each of which is supported against the side of a building by an adjustable brace which at one end engages the bracket at the apex of the angle between a platform supporting portion and a building engaging portion of the bracket, and, at the opposite end, is fixed in the ground, and by providing a rigid platform which is adapted to be supported on the supporting portions of the brackets and to be clamped thereto, and means being provided whereby the platform may be raised and lowered while suspended from a pair of ladders.

For a more complete disclosure of my invention reference is now made to the following specification, in connection with accompanying drawings in which- Fig. 1 is a front elevation showing the application of a staging embodying my invention to a building.

Figs. 2 and 3 are detail front and side views of one of the brackets which I employ.

Fig. 4 is a side elevation of the construction shown in Fig. l. i

Fig. 5 is a detail top plan view of a portion of one of the brackets.

Fig. 6 is a detail view of a portion of one of the braces. Y

Fig. 7 is a detail view of a portion of the platform suspending means.

Fig. 8 is a detail view of the ground engaging end of one of the braces.

According to my invention I provide a pair of brackets I each of which comprises a building engaging portion II and a platform supporting portion I2 which extends at right angles therefrom and is rigidly connected thereto by fastening means (notshown) at the junction thereof' and by two pairs of braces I3 and I4 which extend obliquely from one to the other. While these braces may be secured to the side edges of the portions II and I2, ribs I and I6 are preferably secured to the middle portions thereof and the ends of said braces are secured to said ribs, said braces being thereby spaced apart to provide a socket between said braces and between the surfaces of said ribs I5, II, which meet at right angles in a transverse line, and in which an end of a brace I8 is adapted to be inserted, as will be explained. A transversely extending foot piece is secured to the engaging portion I5 at the junction thereof with portion I2, and a similar foot piece 2l is secured to portion I I adjacent 20 its opposite end, the piece 2| preferably having a pair of friction rolls 22 mounted thereon.

Each brace I8 has at one end a somewhat wedge shaped portion I9 of substantial width, which is adapted to engage the bottom of the socket along the transversepline at the apex of the angle between the ribs I5, I6, and the opposite end ofthe brace has' a sharp metal extension 24 secured thereto, which is adapted to be inserted in the ground to hold the brace securely in position. The brace I8 is also preferably made adjustable in length by any suitable means, the means shown comprising a pair of clips 25 which permit the two sections of which the brace is composed to be telescoped and a bolt 25 to hold 35 them in adjusted position. The braces I8 are straight and rigid, so that they will not buckle 1n use.

A platform 28, which preferably consists of a single stout plank, is provided, which is adapted to be placed on the portions I2 of the brackets and to be clamped thereon by clips 29 and 30, the clip 29 being fixed at the outer end of portion I2 and the clip 3 being adjustable, so that, after the platform has been placed in position on the brackets with one edge against the clips 2S, the clips 30 may be adjusted against the opposite edge, and as the ends of the clips have a right angulariend portion which engage the top side of the platform, the latter will be Securely held on the brackets.

To provide a convenient means for placing the platform in position and for supporting it while adjustments are being made, two ladders 32 are placed against the building close to the positions in which the brackets are held, as shown in Fig. 1. A pulley 33 is attached to the top portion of each ladder and a rope 34 is passed over each pulley and provided with two end portions 35 to which hooks 36 are attached. Staples 31 are secured in each edge of the platform with which the hooks 36 are engaged, as shown in Fig. '1, so that the platform may be suspended from the rope 34 and may be readily raised and lowered thereby.

In placing the staging in position, the ladders will be first placed against the building, as shown in Fig. 1, and the platformwill be raised above Vthe position in which the brackets are to be held.

The braces I8 will then be inserted in the sockets of the brackets, as shown in Figs. 1, 2 and 4, and the brackets will be raised to the required level, with the foot pieces 20 and 2| resting against the side of the building. The metal extension 24 on the lower ends of the braces will be forced into the ground, as shown in Figs. l and 4, so that the braces will be securely held in position. The platform will then be lowered onto the brackets and secured in position by the clips 29, 3E), so it is then ready for use. The ladders will be left in position and used by the workmen in climbing onto the staging. When weight is placed on the platform the downward pressure will be Aresisted by the thrust on the braces I8 longitudinally thereof, and the foot pieces on the brackets will be forced against the side of the building. The staging will thus be securely held in position. The friction rolls on the lower foot pieces, while not necessary are desirable as they prevent these foot pieces from catching on the wall of the building and preventing the upper foot pieces from being pressed firmly against the wall.

As a matter of additional security, the ropes 34 will usually be tied to the ladders, as shown in Fig. 1, so that if the braces I8 should become misplaced, the platform would still be suspended. Such an occurrence is, however, practically impossible if the ends of the braces are securely set into the ground.

' The brackets with the platform thereon may be raised to a limited extent by moving the lower ends of the braces into closer proximity to the building and may be lowered by moving them further away from the building, the ropes 34 being shaped brackets, each arranged to provide a wall engaging portion and a platform supporting portion and a socket at the vertex of the angle between said portions, a stiff brace for each bracket having one end adapted to be engaged with the bracket in the socket thereof and having the opposite end adapted to be fixed to the ground, a platform on the supporting portions of said brackets and means for supporting theplatform independently of said brackets and for raising and lowering it with relation thereo.

2. A staging comprising a pair of right angular shaped brackets each arranged to provide a wall engaging portion and a platform supporting portion, astiif brace for each bracket each having one end adapted to be engaged with the bracket adjacent the vertex of the angle between said portions thereof and having the opposite end adapted to be fixed to the ground, a platform on the supporting portion of said brackets, a pair of ladders, and means for supporting the platform from said ladders and for raising and lowering it with relationthereto.
