JOHN B. KENISON AND MICHAEL F. BURK, OF LYNN, MASSACHUSETTS.

sTAGlNG -BRACKET.

SPECIFICATION forming part of Letters Patent No. 511,625, dated December 26, 1893.

Application filed May 10, 1893. Serial No. 473,663. (No model.)

To all whom it may concern.-

Be itknown that we, JOHN B. KENISON and MICHAEL F. BURK, of Lynn, county of Essex, State of Massachusetts, have invented an Improvement in Staging-Brackets, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention has forits object to improve the construction of folding staging brackets, as well as means for securing the same to a building.

In accordance with this invention a wall plate and sole or support for the stage boards, are pivotally connected together, and a two part brace is provided also pivotally connected together, the extremities of said parts being pivotally connected to the wall and sole plates respectively. A suitable locking device is provided for locking the two parts of the brace in alignment in operative position. A rod having a screw threaded outer end is secured to the bracket, as to the sole plate for instance, which is intended to project through the side of the building, and an adjustable cleat is arranged on said rod, adapted to span two of the usual studs or risers of the building, its adjustability permitting it to span two studs or risers regardless of the particular point through which the rod projects, and a hand nut is turned on said rod which binds the cleat firmly against the studs.

Figure 1, shows in side elevation a folding stage bracket embodying this invention; Fig. 2, a view showing the adjustable cleat; Fig. 3, a view of the bracket, folded, and Fig. 4, an edge view of the locking device for the brace.

The wall plate CL, and sole 1) are arranged at right angles to each other, and pivotally connected together at 2. A brace connects the extremities of the wall and sole plates, composed of two fiat metallic rods or bars 0, c, pivotally connected together at 3, the extremities of said bars being pivotally connected with the wall and sole plates at 4. One of the parts as c has a notch 0 at one side which receives a stud c projecting from the part c, and a thumb screw 0, passes through the part c, which enters a hole or socket in the part c. The end of the thumb screw is upset, so that it cannot be readily removed from the part c. A locking device is hence formed for the two parts or members of the brace rod.

A rod or bar d, is secured to the bracket, as to the sole plate for instance, which projects rearwardly and passes through a slot in a cleat d, of suitable length to span or embrace two ordinary studs or risers of a building. The outer extremity of this rod 01 is screw threaded and receives upon it a hand nut d The bracket is applied to the exterior of a building in process of construction, by projecting the rod cl through the boarding, regardless of the position of the studs or risers, then moving the cleat in one or the other direction as required so as to engage two studs, after which the hand nut (1 is turned, clamping the parts in position.

The advantage of providing an adjustable cleat is quite material as it enables the application of the cleat at any desired point on the exterior of the building without regard to the interior arrangement of the studs.

The brace rod is herein shown as folding inwardly when the bracket is folded, but it is obvious that it may fold outwardly without materially changing the construction.

In a folding bracket, the wall plate a, sole plate I), pivotally connected therewith, a brace rod connecting the outer extremities of said plates, and comprising two parts 0, a, pivotally connected together and to the plates, and a locking device for fastening the two parts of the brace rod securely together, substantially as described.

In testimony whereof we have signed our names to this specification in.the presence of two subscribing witnesses.
