WILLIE WELLS, OF LAKE CHARLES, LOUISIANA.

SCAFFOLIDING.

To all whom it may concern:

Be it known that I, WILLIE WELLS, a citizen of the United States, residing at Lake Charles, in the parish of Oalcasieu and State of Louisiana, have invented certain new and useful Improvements in Scaffolding, of which the following is a specification.

This invention relates to improvements in scaffolding, and particularly to scaffolding for cleaning windows, painting, clap-boarding, repairing, etc, and has for an object the provision of improved means for holding one or more platforms rigidly secured in position in proximity to the window for permitting operation thereon.

Another object in View is the provision of hooks and braces arranged to engage the frame of a window for holding in position a platform on the outside of the window in such a manner as to easily support an operator in cleaning or working upon the window.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more fully described and claimed.

In the accompanying drawing: Figure lthrough a window and scaffolding.

Referring to the drawing by numerals, 1 indicates a window of any desired kind to which is secured or attached the scaffolding used for cleaning, repairing, or otherwise operating upon the window from the outside. The scaffolding is provided with a plurality of platforms 2, 3 and 4t having cleats or extensions which prevent the same from moving their supporting arms in a longitudinal direction. Positioned astride of arms 5 and 6 are supports 9 and 10 and also 11 and 12. The supports 9 and 10 are adapted to rest upon the window sill on the outside and are preferably formed with feet or supports arranged at a slight angle for accommodating the angle of the window sill. The supports 9 and 10 are preferably held in place by a plurality of bolts passing entirely therethrough and through the respective arms 5 and 6 so as to rigidly hold the supports against movement. Supports 11 and 12 also are formed with feet extending at a slight angle for accommodating the angle of the window frame as clearly seen in Specification of Letters Patent.

Application filed September 8, 1909.

Patented May 24., 1910.

Serial No. 516,710.

Fig. 2, and are held in posit-ion upon arms 5 and 6 respectively by any desired means, preferably by bolts passing entirely through the supports and arms. The arms 5 and 6 are formed with a plurality of apertures for adjusting supports 9 and 10, and also a plurality of apertures for permitting the adjustment of supports 11 and 12 to accommodate the same to any sized window and also to vary the distance that the platforms are positioned from the window. Pivotally secured to arms 5 and 6 are hooks 13 13 that are formed with a plurality of apertures for accommodating bolts 14.--1 1 which pivotally secure the hooks 1313 to the respective arms 5 and. 6. Secured to arms 5 and 6 are braces 16 and 17 that may be adjusted by moving their securing bolts 18 and 19 from one aperture to another in thebrace. The braces are formed at their upper ends with a lug or extension 20 as seen in Fig. 2 for engaging the upper part of the window frame. The braces extend beyond lug 20 a short distance and-are provided withspurs or brads 21 that are adapted to be forced into the window frame for preventing any slipping of the braces. By thus constructing a scaffolding with hooks 13-13 and braces 16 and 17 with the lugs 20 and brads 21 means are provided that will positively hold the platforms correctly in position. The cleats will ordinarily prevent the platforms from being removed from their supports, but if desired hook shaped bolts may be passed through the platforms and engage their supports for positively holding the platforms in position. After the scaffolding has been placed in position on the window the operator may then take his position upon any of the platforms and thoroughly clean the window from the outside, or repair the same, or otherwise operate upon the window as may be desired.

The scaffolding is particularly advantageous in cleaning windows as the same may be applied and removed readily to any window and without injuring the same, but at all times presenting means by which the operator may reach all parts of the window for thorough cleaning thereof.

In order that the operator may be positioned at various heights, platforms 2 and 1 are provided above and below platform 3, which rests on arms 5 and 6. Depending hooks 2222 and 2323 engage arms 5 and 6 at their upper ends, and are secured by suitable bolts or rivets to supporting bars 24 and 25 at their lower ends. Platform 1 rests upon the supporting bars 24 and 25 in a similar manner to the way platform 3 rests upon arms 5 and 6, and is constructed in the same manner. Platform 2 is constructed similar to platform 3, but rests upon cross bars 26 and 27 which are supported by links 2828 and 29-29.

In order to prevent any undesirable pivotal movement of links 2828 and 2929 retaining links 30 and 31 are provided which are pivotally connected with bars 26 and 27 and are adjustably and pivotally connected with braces 16 and 17. In connection With the bolts 18 and 19, and also the other adjusting bolts used, winged nuts are preferably provided, so as to permit ready application and removal of the bolt for adjusting or mounting and dismounting the scaffolding.

In order to more firmly brace platform 2 and its supports, cross bars 32 and 33 are secured to the outer uprights 28 and 29. Each of the bars 32 and 33 are formed into parts and secured together by a suitable bolt, which may be fitted into any of the apertures formed in the bars, so as to adjust the length of the bars as occasion may require.

hat I claim is:

1. In a device of the character described, a pair of supporting arms, a hook for each of said arms engaging the inner part of the window frame to which the device is attached, a brace associated with said arms engaging the top and bottom of the framework of said window for bracing said arms, a movable platform mounted on the outer end of said arms, a plurality of hook shaped members engaging said arms and depending therefrom, means for bracing said depending hook members, a platform movably mounted on said last mentioned bracing means, pivotally mounted upstanding braces projecting from said arms, connecting bars for connecting each pair of said upstanding members, a platform mounted on said connecting bars, and means for adjustably connecting each of said connecting bars with said first mentioned brace.

2. In a device of the character described, a pair of supporting arms, hooks for holding the same in position, a platform mounted on said arms, upstanding members extending from said arms, cross bars connecting said upstanding members, a platform mounted on said connecting bars and arranged in vertical alinement with said first mentioned platform, depending members extending from said arms, means for connecting a platform to said depending members, said last mentioned platform being in vertical alinement with the first two mentioned platforms.

In testimony whereof I aflix my signature in presence of two witnesses.
