PATENT SCAFFOLD.

SPECIFICATION forming part of Letters Patent No. 776,668, dated December 6, 1904.

Application filed March 25, 1904.

To all whom it may concern:

Be it known that I, THEODOR MAcnARAonoK, a subject of the German Emperor, residing at Dusseldorf, in the Kingdom of Prussia, Germany, have invented a new and Improved Scaffold, of which the following is a specification.

My invention relates to a free-hanging selfsustaining scaffold for the fronts of buildings to be used chiefly by sculptors, painters, and repairers, &c.

According to my invention poles are screwed into sockets fitted in the wall of the building. These poles are connected by a peculiar system of hangers and diagonal braces carrying turnbuckles. For the reception of the poles bearing the planking the ordinary sockets are employed.

My new scaffolding differs from the older forms in use in that owing to the peculiar strutting it can be much more lightly construeted and juts farther out without losing in firmness or hearing power.

My invention is represented in the accompanying drawings, in which Figure 1 is a front view of a building with the scaffold in position. Fig. 2 is a vertical cross-section of Fig. 1. Fig. 2 shows a bearing-pole with joint; Fig. 3, a section of socket let into the wall for securing the braces. Fig. 4: shows the socket with the locking arrangement. Fig. 5 is a cross-section on line A B, Fig. 9.; and Fig. 6, a cross-section on line C D, Fig. 3.

In the front wall of the building threaded sockets a, divided at their bases, are let into i are sustained in the following manner: At the front and rear the poles carry plates 0 and d with holes or slots 0 for the reception These poles project Serial No. 200,072. (No model.)

vertically below plate (Z. This hanger is therefore inclined forwardly from the front of the building, Fig. 2, but not laterally. After the hanger is secured in position it is adjusted to the proper length by a turnbuckle or other similar means, so that the free end of the undcrmost pole is secured to the wall by means ofthe hanger f, plate (Z, and socket (1.. hen the upper part of the scaffold has been erected in this manner, it can be used for hanging in other poles b and hangers f till the whole is completed.

In addition to the hangers f" the poles b are connected by braces that extend paral lel to the house-front and connect the front of an upper pole to the front of a lower pole, which is situated to the left or right thereof. Thus the braces f extend in a lateral direction and cross each other, Fig. 1. As shown, the central upper pole Z) is connected by a brace f to the lower lateral pole, and similarly the upper lateral pole is connected to the lower central pole, so that a thoroughlybraced structure is produced.

The scaffolding in question may be made to project a great distance and this without great difiiculty, a great advantage when it is required to secure it in front of projections, as balconies, See. In such cases longer bearing-poles are employed, or several poles are screwed one onto the other until the desired length is attained.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A self-sustaining scaffold composed of a series of horizontal poles projecting from a house-front, hangers that connect the inner end of one pole to the outer end of a pole next below, and a platform supported upon the poles, substantially as specified.

2. A self-sustaining scaffold composed of a series of threaded sockets sunk into a housefront, threaded poles engaging the same, platforms supported upon the poles, hangers that connect the inner end of one pole to the the front plate of another laterally-located outer end of a pole next below, and diagonal pole, substantially as specified. 5
