Letters Patent No. 62,234, dated February 19,1867.

IMPROVEMENT IN LADDERS.

TO ALL "WI-IOM IT MAY CONCERN: y

Be it known that I, DANIEL B. TAYLOR, of the town of Avon, and county of Oakland, in the State of Michigan, have invented a new and improved Ladder; and I do hereby declare that the following is a full and exact description thereof, reference being had to` the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists'in providing a ladder with a movable carriagefwith a seat and step attached thereto, which can be moved'np or down the frame (or side pieces) by means of shaft-crank and belt. In the drawingsi Figure l represents a perspective view.

Figure 2, a sectional view.

A represents the frame or side pieces of the ladder, which consists of two pieces of scantling of suicient l stren th to hold the wei ht re uired. The are fastened at a convenient distance a art b means of crossieces g g (i Y P Y P at each end. O represent two legs, which are fasten'ed to the top of frame A in such a manner that they can be placed at any angle` required, so as to give the frame more or less pitch. B represents the frame of carriage, which is made of such width as will allow it to'move inside the frame A. I represents a seat, on which the operator may sit, and is attached to frame B.` C represents another frame, which is inside of and attached t0` frame B by means of shaft E. D represents a step, fastened to frame C, upon which the operator may stand. N represents a shaft, which passes through the frame B, the ends of which project beyond the sides of frame B; and upon each end there is a friction-roller, which runs upon thevframe A. K is a. crank, which is attached to shaft E, which shaft passes through the frames D and B, and projects far enough to rest on frame A, which supports the frames B and C, and keeps them in their proper position. F is a; ratchet-wheel, which is fastened to shaft E. G is a pawl, which is fastened to frame B in such a position that, when the operator has reached the position he desires, the pawl is placed in Contact with the ratchet-wheelF, which will hold the frame B in any position or place desired. L is a shaft, fastened at each end to frame A'in suche. manner that the shaft can revolve. M represents a band, which is fastenedat one of its ends to shaft E, and passes over shaft L, and returns to and is fastened to frame B.

The ladder is operated as follows: The frame A is elevated to any pitch desired by placing the legs O at the proper distance from the lower end of frame A. The operator, placing himself on the seat I, turns the y shaft E by means of crank K, which winds theband M around the shaft E, thereby drawing the frame B towards the top of the ladder.

Having thus described my invention, what I'claim as new, and desire to secure by Letters Patent from-.the

United States, is- V v 'p The application to laddersof a movable frame B, having a step D and seat I attached, together with frictionrollers I, band M, crank K, ratchet-wheel F, and' pawl G, constructed and operated substantially as above DANIEL B. TAYLOR.
