UNITED STATES PATENT OFFICE.

CHARLES E. FLAGG, OF SHERBURNE, MASSACHUSETTS.

PLATFORM-SUPPORTER.

Specification of Letters Patent No. 15,099, dated June 10, 1856.

To all whom it may concern:

Be it known that I, CHARLES E. FLAGG, of Sherburne, in the county of Middlesex and State of Massachusetts, have invented a new and useful or improved platform-supporter to be applied to a roof and for the purpose of supporting and adjusting a platform during the process of shingling or slating said roof, my said invention being also applicable to various other purposes or uses during the construction or repair of a build ing or the roof thereof; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which-- Figure 1, is a top view of my invention as applied to a roof. Fig. 2, is a side elevation of it. Fig. 3, a vertical, central and longitudinal section of it.

In the process of fastening shingles or slates to a roof, it becomes necessary to arrange and support at difierent elevations on the roof, horizontal planks or platforms for the support of the workmen, their tools, and the materials which are to be fastened to the roof. The common mode of fixing and applying such platforms is attended with much expenditure of labor, and has disadvantages that are well understood by carpenters and slaters.

My invention is a portable contrivance which may be applied to a slanting roof or other part of a building, and for the purpose of supporting one or more stages or platforms and to enable such to be elevated as the work of shingling or slating or other kind of covering may progress.

In the drawings A, denotes what I term the fastening bar; it consists of a bar of wood or other proper material, provided with perforated ears or projections a, a, through which screws may be passed so as to confine said bar to a roof B. On the upper surface of said bar, is another or slide bar C, which slides longitudinally between guides b, 6, extending upward from the upper part of the bar A. A lever pawl or click D, is applied to the bar C, and arranged as seen in Fig. 3, it being made to work in a rack or series of notches arranged in the bar, A, as seen at, e, in Fig. 3. One or more bearers or short bars E, is hinged to the slide bar, C, as seen at f, in the drawings, and each of said bearers is provided with a strut, F, hinged to it as shown at, 9, there being formed in the bar, C, or that immediately under said strut, a series of notches or recesses, it, into some one of which, the foot of the strut may be stepped, when the bearer, E, is brought into a hori zontal position. Two or more supporters constructed as above described are to be used at the same time for supporting a platform or plank (it being placed thereon as shown by dotted lines in Fig. 2) and these may be applied to the slide bar, C, of each as many of the bearers, E, as may be necessary. I however prefer to make the article with but one or two of them arranged at the upper and lower ends of the bar, G, as shown in the drawings.

It will readily be seen that when the bar A, has been fastened to a roof the bar, C, may be moved upward in order to change the posit-ions of the bearers, and the elevation of the platform, as circumstances may require.

I claim as my invention The improved platform supporter, or combination of the fastening bar A, the slide bar, C, the bearer, E, and the strut F, as applied together and to be used substantially in manner and for the purpose as above specified.

In testimony whereof, I have hereunto set my signature this fifteenth day of April A. D. 1856.

CHARLES E. FLAGG.
