WINDOW-PLATFORM.

To all whom it mayv concern:

Be it known that 1, DAN NEWTON, a citicity of Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in l/Vindow-Platforms, of which the following, taken in connection with the ao-' companying drawings, is a specification.

The invention relates to window platforms or scaffolding for the use of window cleaners, glaziers and similar workmen;

and the object of the improvement is to provide a durable and strong knock-down window platform construction which is supported on the window casing at each side so that it can support heavy weights, holding rigidly in place when set up, the assembling being easy of accomplishment and the parts adjustable to different sized windows; and the invention consists in the novel features and combinations hereinafter set forth and claimed.

In the drawings, Figure 1 is a perspective view of the preferred form of the window platform, showing the construction I and arrangement of the same. Fig. 2 is a plan view of the window sill with the inner ends of the holding brackets supported by the cross rod in position against the window casing, the wall and casing being shown in section and the outer portion of the brackets being broken away. Fig. Bis a perspective view of one of the supporting brackets in'position upon the window sill, the wall being shown in section. Fig. 4 is a side elevation of one of the preferred forms of clamps for holding the platform on the supporting brackets and giving rigidity to the entire structure; and Fig. 5 is a perspective view of the adjustable looking rod for holding the inner ends of the brackets against the innerside of the windowcasing; and Fig. 6 is a perspective.

L1ke characters of reference refer to corresponding parts in'the several views.

"and the upwardly projecting outer end 16..

The barl3 is bolted to'the outer end of the barv 12 at 17, and'the cross bar or brace 14 is bolted at 18 to the bar 13 and at 19to the bar 12. y W

A cross rod 20 is provided which slidably fits through the holes 15 of each of the brackets 10 and 11, and extend out each side of said brackets to bear against the inner side of the window casing 21. For finely finished casings, a tubular covering 28 is provided for the rod 20 to prevent marring the finish.

The platform 23 preferably has the railing 24 thereon and when the brackets 10 and 11 are placed in position. upon the window sill 22 at each side of the window and the rod 20 is inserted in position to hold the same with the lowerends 25 of the bars 13 resting against the wall of the building, the platform 23 canbe placed. 7

upon said brackets 10' and 11' and hold firmly in position by;means of the screw clamps 26 and 27, which clamps bear on the under side of the bars 12 and the upper side of the platform 23.

It is apparent that thlsconstruction gives 1 a knock-down and easily adjustable window platform which isheld; rigidly in position by means .of the cross bar 20, and which holds the workman in position without, danger of falling, the supp'ortof the rod I 20 being sufiicient touphold an exceedingly construction is such that while durable, it

is exceedingly easy' of manufacture and assemblage.
