Letters Patent No. 60,085, dated November 27, 1866.
CHARLES M.` TANNER, or MENTOR, omo.
l SPCIFIOATI'ON. TO ALL WHOM IT MAY GONGERN:
Be it known that I, CHARLES M. TANNEB, of Mentor, ih the county of Lake, and State of Ohio, have invented a new and useful improvement in Extension Scaiiolds; and I do hereby declare that the following isa fulland exact description thereof, reference being had to the accompanying drawings, in which-f Figure 1 is a view in perspectiveof my said improved extension scaoldwith the stage orplatformelevated. Figure 2, a perspective view of 'one of apair of framed extension legs for extending the platform still higher; and
Figure 3, a side elevation with said framed legs attached.
Similar letters of reference indicating the same-parts in all the drawings. .l l
The main feature of my improvements consists yin the mode employed for hoisting the frame hf the stage or platform of the sca'old to -the required height,:byfnieans of additionalor auxiliary pairs of supports, which it into and connect with the framed supports of the said, stage or platform, and `by means oi' Athe same windlass which is used for-raising said frame, by simply removing the hoisting-ropes from the one and `attaching them to the others, as'will beexplained. Secondly, in the manner of constructing and operating the main frame so that the stage or, platform frame is kept steady and free from swaying 'whilst elevating, as will be shown.
The following is a description of the construction and operation of my said improved extension scaifold:
The main frame consists of four upright posts, A, iig. l, secured together by eight ties,'B, B B", as seen.; The two lower ties,B, support a roller-wndlass, C, on which is a'pawl and ratchet, not seen. Angular recesses,
one of which is seen atl), are formedon each pair of 'said posts, on their outer sides. Under the upper pair of ties; B, are pulley-blocks E Iand E. This completes the main or 'stationary frame. The other-,'or"sliding-frame,
is 'constructed thus: Two pairs of legs, F, `are framed by ties G and plates G', the lower ties having holes, G", l for attaching the hoisting-ropes, hereafter mentioned. 0n the top of this frame is the stageorplatforml. The
said frame is connected` with the main frame by the pairs of legs, F, and iits into the recesses, D,`in whichtlilcy slide up and down. They are kept in place by long iron guide-plates, I.: Two hoisting-ropes, .I and J', from the windlass, are passed through pulleys E', yhung under the ties, B, as sen, and. are' secured to the ties, G. Fig. 3 represents one of a pair o f additional framed legs employed in connection with the before-,mentioned sliding and main frames. It consists of two legs, K," and ties K and K. i Secured on the upper ends of said legs are cast-iron sockets L L, made to t and receive the lower part ofthe legs of the slidinglfame, as shown.
The lower tie, K and the corresponding tie are provided with holes, M, through which the ends of the hoisting- `ropes are secured for elevating the platform. V t
The operation is thus: By turning the windlass the stage' is elevated-the pawl and ratchet retaining it at p the desired height. When it is required to raise the stage 'still higher the auxiliary pairs of framed legs are united with those of thesliding-frame by means of their sockets, L, the saidsliding-frame being first temporarily supported by pins, N, g. 1. The ropes are then removed-from the sliding-frame and fastened to the said auxiliary pairs, and the process of elevating the stage is conducted as with the first or sliding-frame; and so with b as many pairs asare needed to reach the desired elevation. Y
Iclaim the sliding-frames which support the'stage or platform H, in combination with the main frame con# structed with recesses D, guide-'plate I, windlass C, hoisting-ropes E and E', and `additional pairs of framed legs provided with sockets L, as herein described, and operating as and for the purpose set forth.
' CHARLES M. TANNER.
