IMPROVEMENT IN ROOFI-NG-SGAFI'OLD.

TO ALL WHOM IT MAY CONCERN:

Be it known that. I, PETER. RICHMOND,/of Aberdeen, in the county of Ohio, and-in the State of Indiana, have invented certain new and useful Improvements in Roofing-scaffold; and do hereby declare that the follow# ing is a. full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the lettersA of reference marked thereon.

In the annexed drawings, making part of this specification, A A represent two pieces of thick board or` narrow scantling, with their upper ends bevelled at about an angle of forty-five degrees. 'These pieces are placed parallel to each other, and at a suitable distance apart, and are connected by means of a board, B, secured fast to their hevelledA edges. A frame, C, connected by cross-pieces Fand G, is placed between the two pieces A A, and connected to them by means of bolts E and D. v The frame-pieces C C are provided with a series of holes, a a, for the bolt I), so that the frame can be adjusted, with reference to the pieces A A, to suit the pitch ofthe roof upon which this bracket is Ato be used. Instead ol' the frame C C, I inlay bring the pieces A A close enough together to embrace a single piece of soantling, II, as -seen in Figure 4. Two bolts will connect the scantling H to the piecesA, as in the other case, the outer or lower bolt having,r several holes'to regulate the pitch of the scaffold. Metallic plates I I, provided with suitablepoints, are secured toJ the lower ends of the frame-pieces C C or H, and to the under side of the boards B B at each end'.

When this scaffold is placed upon the roof of' a building, the points of the plates I I catch linto the said roof, and station the scaffold at any desired point. Two or more of these scatfolds may be used upon a root` in line with each other, and a Scofield-board laid from one to the other, furthe purpose of forming a long scaffold.

,Having thus fully described my invention, what I claim-as new, and desire to secureby Letters Patent, is-

The side pieces A A, vplat-form; B, plates I I, and the frame C C or seantling H, for forming a scaffold, the several parts being constructed and used substantially-as and for the purpose set forth. p

In testimony that I claim theforeroing, I have hereunto set my hand, this 4th da);r of September, 1867.
