SUPPORT FOR SWlNGlNG OR PENDENT SCAFFQLDS.

SPECIFICATION forming part of Letters Patent No. 288,977, dated November 2'7,

Application filed August .21, 1883. (No model.)

To all whom it may concern.-

Be it known that I, JAMES T. CHURCHILL, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented a new and useful Support for Swinging or Pendent Scatfolds, of which the following is a specification.

The object of my invention is to provide a strong, light, safe, and easily-n1ovab1e swinging scaffold for the use of carpenters, painters, galvanized-cornice workers, and builders generally. They are hung from cornices or any other projections or supports where the hook can get a firm hold. To place in position for use, two or more of them are drawn up by a rope, or carried up through a building, and hung from a cornice or other support, about twelve or fifteen feet apart. The scaffold: board is placed in position by tying a rope three or four feet from each end of the board and. letting the same down at an angle of about forty-five degrees, sliding one end into the bottom of one support, thenlowering the other end and moving slightly backward into the other; or place board in position on the ground and draw up supports with ropes. The weight of two supports and a board one and a half inch thick and fourteen feet long will not ex ceed fifty-five pounds, and is easily moved by one man at each hook sliding it along the cornice. The support is designed to be used in pairs by painters, with scaffold-board twelve or fifteen feet long. By cornice-work ers and others they should be hung at intervals of twelve or fifteen feet, with scaffoldboards between, forming scaffold the entire length or width of a structure. I attain my objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 represents the support entire. Fig. 2 represents the notched board shown in lower part of Fig. 1. Fig. 3 represents board or slat for raising scafi'oldboard. Fig. 4. represents small wooden wedge seen at bottom of Fig. 1.

G G G, Fig. 1, is an acute triangular frame constructed of clear straight-grained pinewood.

A. is a flat wrought-iron hook, twisted to strengthen it at top, and is securely bolted to top of frameG GG with two threc-eighthsinch iron bolts, as shown.

B B B are wooden steps or rungs (set into edge of and secured to frame G G G with heayy screws) to come down from or go up on the roof or other support from which they hang.

G G C C, Fig. 1, are thrce-eighths-inch roundiron staples secured to frame G G G by clinching. They are used as receptacles for boards shown in Figs. 2 and 3.

D, Fig. 2, is a notched board of hard wood, three and one-half feet long by one inch thick. It is used in the two lower staples G C, Fig. 1, as a rest against the wall to prevent the scaffold from swinging in or outward from the building.

E, Fig. 3, is a hard-wood board, five feet long by one inch thick, used in upper staples C C, Fig. 1, to raise scaffold-board higher when necessary; also, to use in lower staples C C, Fig. 1, to widen scaffold by laying an extra board on each side of center scaffold-board.

F, Fig. 4, is a small wooden wedge to secure notched board 1), Fig. 2, to bottom of sup port, as shown at F in Fig. 1.

I claiin In a pendent scaffold-bracket, the combination, with the triangular frame, of the supporting-hook, the steps, and the staples, and the cross-pieces therefor, all substantially as and for the purpose specified.

JAMES T. CHURCHILL.
