JOHN K. LEMON, OF TOLEDO, OHIO.
BUILDERS SCAFFOLD.
Specification of Letters Patent No. 27,815, dated April 10, 1860.
To all whom 'it may concern: r
Be it known that I, .IoHN K. LEuoN, o Toledo, in the county of Lucas and State of Ohio, have invented a new and Improved Scaffold for Building Purposes; and I do hereby declare that the following is a full, clear, and exact description of the same, ref# erence being had to the annexed drawings, making a part of this specification, in
Figure 1, is a longitudinal section of a scafold constructed according to my invention. Fig. 2, is a transverse section of ditto. Fig. 3, an venlarged side sectional view of one of the blocks with its clamp or band.
Similar letters of reference indicate corresponding parts in the several figures.
To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.
A, represents a series of uprights the lower ends of which have each a base strip a, secured to it properly braced. Any proper number of uprights may be used according to the length o-scafold required, the uprights being placed about seven and a half feet apart and about 4gfeet from the wall B, of the building. The uprights A, are of quadrilateral form and of any suitable height and on each upright rectangular metal bands C, are placed. These bands are made of flat bars and the bands are considerably longer than the thickness of the uprights sufficiently so to admit of a wedgeshaped block D, being inserted in them, as shown clearly in Figs. 2, and 3. Each block D, is slotted longitudinally, as shown at ax, the slots being parallel with the outer sides of the blocks which are inclined, the inner sides adjoining the uprights being parallel with the latter, and in each band C, a pin or rod Z2, is fitted transversely, said pins or rods passing through the slots in the blocks.
The bands C, it will be seen will retain the blocks D, at any point on the uprights, the blocks when subjected to weight being forced down and firmly wedged between the bands and uprights. The blocks may be adjusted to any desired point by simply raising them in the bands which movement causes the blocks in consequence of their inclined outer sides to recede from the uprights.
To form the scaffold the lowermost blocks D, are irst adjusted on the uprights at a height coinciding with that of the wall B, and the putlogs E, are laid one end on the wall and the other end on the blocks D, as shown clearly in Fig. 2, the flooring plank F, being simply laid on the putlogs without being nailed. Then the wall is built up suiiiciently to require a second ooring on the scaffold, the uppermost blocks D, are raised on the uprights and secured to them at the proper points the putlogs placed on them and on the top of the wall, and the flooring on the lower putlogs removed and placed on the upper putlogs. By this arrangement the scaffold may be very readily erected and taken down, and increased in height as required with the greatest facility and a very firm and secure scaffold obtained. The pins or rods b, itting in the slots ax, of the blocks serve to keep the bands and blocks together, and when the blocks are moved up or down, the slots allow of such movement without disturbing the position of the bands. Thus the blocks may be driven down more firmly whenever desired by blows upon their upper ends without moving the bands.
Having thus described my invention what I claim as new and desire to secure by Letters Patent, is-
The employment of the slotted wedge blocks D, in combination with bands C, pins o, and uprights A, as and for the purpose herein shown and described.
JOHN K. LEMON.
