V WlNDOW-SCAFFOLD.
SPECIFICATION forming part of Letters Patent 0. 678,115, dated July 9, 1901.
Application filed October 8, 1900. serial No. 32,349. (No model.) I i To all whom, it may concern:
Be it known that I, Bonner GUENTHER, a citizen of the United States, and a resident of Jersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in W'indow-Scaf folds, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.
This invention relates to improvements in window-scaffolds. V
The nature and object of the invention will be fully understood from the following general description and the annexed drawings and will be subsequently pointed out in the claims.
Figure l is a View of a window in elevation with my newly-invented scaffold attached. Fig. 2 is a sectional view of the same, taken on the line y y of Fig. 1. Fig. 8 is an inverted view of my scaffold with part of the window=sill attached. Fig. 4 is asectional view taken on the line 001m of Fig. 3. Figs. 5 and 6 are views of details of the mechanism more fully hereinafterdescribed.
A designates the upper sash of a window, and A the lower sash thereof.
B designates the sides of the win dow frame, and B the sill thereof.
D and D'designate stout bars, preferably of metal. These are adapted to lie on the window sill B, partly inside and partly outside of the window. To the outside ends of these is fastened the frame I. This frame is preferably made of metal and consists of the cross-piece 'i and the segmental bearings z', integral therewith. The segments 71 and 71 are fastened to said bar o" and have extending over the bar t another bar similar thereto and formed with segmental bearings g", similar to the bearings 41 and directly over them. The segmental bearings are constructed and arranged so as to overlap the bars D, one above and one below, and are secured in position by the pins 6 At '6 the bars D are pivoted to the cross piecee". The segmental parts 5 of the frame I are provided with adjusting-holes, in which work the pins e These pins pass through'the bars D and the segmental bearings e' and g, as illustrated,
to hold the said bars at the proper angle. On the bars D also work the clips F. These clips consist of the strapsf, embracing the bars D and the, bracket T The pins f passing through the bars D and series of holes in the bars D, serve to hold these clips in position when adjusted, as hereinafter described. A bracket 9 is also "formed on the under side of each of these bars to rest on the outside edge of the window-sill. Upon the frame I is mounted the seat E. It may be fastened thereto by screws, bolts, or in any common and well-known way. 0 and O designate brace-bars fastened by the double swivel-joints C to the inside ends ofthe bars D. The joints are formed with ears 0, a neck 0 adapted to fit in holes o in the ends of the bars D, and heads'o to hold them in proper position. The bars 0 are fastened to these joints by bolts or pins 0, passing through theears c and the ends-of the bars O. This pivots the bars 0 and D together, sothat they may be swung around in planes at right angles to each other. To the sides B of the window-framesare firmly fastened the brackets a in any adaptable way, as with screws, bolts, and similar well-known means. The bars 0 are hinged by their up per ends to these brackets a by the bolt or pin a, the whole device to 'be substantially as herein-illustrated and described.
To use myinvention, the parts are arranged with regardto the window, as illustrated,-with the bars D resting onthe sill B, adjusted at the proper angle to fit the breadth of the window by means of the segments i and the pins e These bars are prevented from slipping endwise by the brackets g and, the clips F, resting on the edges of the sills B. 'The inner ends of these bars are held'in position by the bars 0, as hereinbefore described, and the seat E, resting on the frame I, is upheld by the bars D outside of the window. If it then be required to clean the window or othwise work at it on the outside, it will be found that the seat E affords a firm and reliable sup port for the operator and that he may sit upon it and work with ease and safety as long as required. When the bars 0 are releasedfrom the brackets a by taking out the pinsor bolts a, the scaffold may be easily lifted out and removed from the window to be fastened, as
hereinbefore described, on another window or to be laid away for future use.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is 1 1. In a window-scafiold, the combination with a bar, formed in two circular segments, integral with each other; two cross-bars, arranged one above the other, and attached to the ends of the segments of said segmental bar, segmental bearings upon the ends of said cross-bars, and all said three bars arranged and adapted to form a supporting-frame; of horizontal bars, pivotally attached to said frame, arranged to be adjustable in said segmental bearings, and to support said frame; braces holding said horizontal bars in position; and a seat surmounting said frame; all
substantially as and for the purpose set forth.
2. In a window-scaffold, the combination with horizontal supporting-bars; and braces holding said bars in position; of double joints, comprising the ears 0, to which said braces are pivotally attached, the heads 0 and the pins 0 by which, in connection with the said ears, the said supporting-bars are pivotally attached to said braces, and said braces and said supporting-bars, so adapted and arranged, and so connected by said joints, that they will swing in planes at right angles to each other; all substantially as and for the purpose set forth.
In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 17th day of September, 1900.
