ORREN G. NOSKER, OF SHELDON, ILLINOIS.

SCAFFOLDING.

SPECIFICATION forming part of Letters Patent No. 391,182. dated Getober 16, 1888.

Application filed May 24,1888. Serial No. 274,989.

To aZZ whom it may concern.-

Be it known that I, ORREN G. NOSKER, a citizen of the United States, residing at Sheldon, in the county of Iroquois and State of Illinois, have invented certain new and useful Improvementsin Scaffolding, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to scaffolding, and the objects and advantages thereofwill be hereinafter described, and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a side elevation of a scaffolding constructed in ac cordance with my invention, the same being set up for use. Fig. 2 is a bottom plan of the platform-sections. Fig. 3 is an end elevation of the lower portion of one of the platformsection-supporting ladders, and Fig. 4 is a perspective of one of the ends of the platform-sec tions.

Like letters of reference indicate like parts in all the figures of the drawings.

A A represent the platform-sections, which are laid one upon the other, and may be of any desired length, width, or thickness. The two sections are held in sliding contact with each other by means of oppositely-arranged arms or bails A a pair of which project from the lower one of the sections up over and embrace the upper section, and a pair of which also project from the upper section down and under the lower section. The lower one ofthe platform-sections,A,is longitudinally slotted, as at A said slot terminating short of the ends of thesection. Secured to and depending from the under surface of the upper section,A, into the longitudinal slot A is a staple or eye, A", which, in addition to other .functions hereinafter described, serves as a stop to the longitudinal sliding of the sections, so as to cause said section to uncouple.

At the outer ends of each of the platformsections, and secured to their under surfaces, are oppositely-arranged sockct'castings A, which are adapted to receive and rest upon either of the supportingrungs of the two oppositely-arranged ladders B B. The height of the platform from the ground may be regulated at will by resting the sections thereof upon higher or lower rungs.

(No model.)

Loosely connected to the staple or eye A* is abrace-rod, A, which is formed with a hooked end adapted to take over one of the rungs of the ladder, forming a brace and preventing said ladder from spreading, and also limits the length or spread of the sections, so that the desired length of platform is secured. From an eye or staple, A secured to the under surface of the lower section, A, there is loosely connected a second brace'rod, A, having a hooked end adapted to take over one of the rungs of the companion ladder at the opposite end of the platform.

Each of the ladders B B is provided with casters or rollers B at its lower ends, so that shifting the scaffolding from one position to another is facilitated.

One of the sides of each of the ladders B, or it may be each of the sides, if desired, is provided with a series of eyes or staples, B through which is passed and adapted to slide longitudinally a locking bar or rod, B The lower ends of the rods B are sharpened or beveled ,and are adapted by means of a handle, 13*, formed at the upper end of the rod, to be forced down into the ground, and thus render the scaffolding stable. A kink or laterallyprojecting arm, B is formed upon or secured to the rod B which, when said rod has been forced into the ground, is designed to be turned so as to take under a projection, B, projecting from the side of the ladder B. By this arrangement the ladder is secured against slipping. By turning the rod B so as to disengage its arm B from the projection B, and raising said rod until said arm is above said projection and then turning the same, the rod will be locked out of contact with the ground and the point retained against scraping or otherwise retarding the easy moving of the scaffolding from one point to another.

Having describing my invention and its operation, what I claim is- 1. In aseaffolding, the combination, with an extensible platform formed of overlapping sections, the outer ends of said sections being provided with rung-receiving sockets, of supporting-ladders mounted at each end of the platform and diagonal brace-rods connecting said ladders and platform, substantially as specified.

2. In a scaffolding, and in combination with the platform thereof, end platform supporting ladders mounted on casters and provided with a vertical rod adapted to be forced into the 5 ground, substantially as specified.

3. In ascaffolding, andin combination with the platform thereof, platformsupporting ladders provided with a locking-rod adapted to be forced into the ground, and means for lock- 10 ing said rod in such position, substantially as specified.

4. In a scaffolding, and in combination with the platform thereof, supporting-ladders pr0- vided with a looking-rod adapted to be forced 15 into the ground,and provided with alaterallyprojecting arm adapted to be thrown into con- -mounted in the eyes, substantially as-specified. 5

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