IMPROVED STAGING.

-.mn I

The Schedule referred to in these Letters Patent and making part Of the same- 'To all who/m, yit-mcy concern Be it known that I, J. E. LONG, of Norway, in the county of Oxford, and State of Maine, have invented a new and useful Improved Stagingor Roofs; and I hereb'y declare the following to be a full, clear, and exf act description thereof, which will enable others' to make and use my invention, reference being had to the accompanying drawings, forming part of this specication, in which is shown a perspective'view of my invention, as seen when in use.

In shinglin'g the roofs of buildings, or performing other work thereon, a staging of some kind is required for the support of the workman and his tools. It is usual to construct it by nailing cleats to the roof, and fastening braces to them, or by some like device. This takes the time of the men, and even then, is not always secure, as the many instances of falling stages prove. As the work proceeds, the stage and supports have to be moved up or down, as the case may be.

A device by which these diiiculties may be obviated, and a stage which may be quickly and securely erected, and moved when necessary, is the subject of my invention.- The accompanying drawings show the nature of it.

It is composed either of wood or iron, and consists of the cross-pieces c b,which are supported by the braces or standards c d. These Apieces are fastened together by the bars e f.

At the extremities y h of c (l are fastened plates of iron, the lower ends of which are toothed, as shown in the drawing, so as' to take a firm hold of theboards or shingles of the roof.4

The ends i j of a bare arranged in like manner. The boards of the stage'or scaffold are laid across on av b,`extendinf,:1r tol another support of alike kind, placed at a convenient distance.

The teeth on the plates are forced into the roof by the weight of the laborers, and held more firmly, the more weight there may be applied. A sudden shock, instead of, as at present, tending to breakdown the scaffold, only makes it more secure,.a1 id when it becomes necessary to change its position,J it can be done expeditiously and with safety.

This device is adapted to roofs vof any pitch, and.

performs its office equally well whether the roof' be steep or not. n

` The inclination of the posts a b to c d is such` that when the device is placed upon the roof of a building, theparts c b form a horizontal or a nearly-horizontal support for the boards, &;c., upon which the Workmen may stand.

' What I claim as my invention, and desire to secure by Letters Patent, isl

The improved portable and self-fastening staging, as described, and for thepurposes setforth.

J. E. LONG.
