JACOB L. LIGI ITNEP OF KNOXVILLE, ILLINOIS, ASSIGNOR OF ONE-HALF TO G. M. D. EWALT AND ISAAC BfGUllLOF SAME PLACE.
SCAFFOLD-SECU RING DEVICE.
SPECIFICATION forming part of Letters Patent No. 540,262, dated June 4, 1895.
Application filed March 12, 1895. $erial No. 541,476. (No model.) i
To aZZ whom it may concern:
Be it known that I, J AOOB L. LIGHTNER, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in ScaffoldSecuring Devices; and
I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appert-ains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specifica- No separating of the parts is necessary inorder to adjust or entirely remove it from the scalfold.
In order that the invention may be fully understood, I will proceed to describe it, with reference to the accompanying drawings, in which-- Figure 1 represents the complete device. Fig. 2 illustrates the manner of operating. Fig. 3 illustrates the yoke in detail. Fig. at illustrates the yoke-link and key-plate in detail. Fig. 5 illustrates in detail the yoke and hook for securing to the building. Figs. 6 and 7 are details of the yoke and key-plate.
A and 13, represent the customary vertical and horizontal parts of a scaffold. B is usually about four feet long. Its inner end rests upon the building and its outer end is secured to the vertical part A. Placed upon the parts B of the scaffold, are boards for supporting the men and material.
To the inner end I) of part B, I secure a yoke 0, between the lower open ends of which is pivoted a hook (I. Upon the back of this look yoke 0.
book is a projection e, which sinks into the lower edge of B and locks the yoke c when hook d is in workin g position, and falls away when out of working position, leaving yoke 0 free to be removed at will. See Fig. 5. This device is used to secure the inner end of part B to the building.
The outer end b of part Bis secured to part A by a yoke G, the open free ends of which receive a plate F formed with an opening f at one end and a slot f at the other end. The arms of yoke G are threaded at g to receive tightening nuts H H. Between nut 11 and plate F is a key'plate I formed with a lip t.
which engages the edge of plate F and secures said plate from displacement.
The operation of the device in putting up the scaffold, is as follows: Hook d is first put to place on the building. Part B is then swung to position causing projection e to securely The outer end 17 of part B is then adjusted to place. Yoke G is slipped to position shown in Fig. 2 and its teeth g are set into the wood as seen in Fig. 7. 'Link F is then swung to position shown in Fig. 1. Keyplate I is placed in position and locked by not II. By tightening the nuts H H the device securely locks parts A and B together.
In Fig. 3 I have shown the yoke G formed with its end arms fiat for a portion of their length for the purpose of affording cutting edges 9 which, in case of slipping or settling of part B, will sink into part A and more securely lock the parts together. With this construction key-plate I is formed with a lip t" to give extra strength to the slotted end f 2 of plate F, as the sinking of part B would have a tendency to spread the arms of yoke G and bring extra strain upon the end f of plate F.
With the construction shown in Figs. 6 and 7, the slightest settling of parts will cause the teeth 9 to sink deeper into part A, and when these teeth are properly set to place, slipping is impossible. With this yoke, keyplate shown in Fig. 6 is used.
To take down the scaffold it is only necessary to release nuts H H, swing link F to position shown in Fig. 2, and yoke G with all its parts may be removed. Part B is then swung down, and hook d is removed.
I am aware that there are similar devices for scaffolds, and I do not claim the device broadly.
Having now described my invention, what 5 I claim as new therein, and desire to secure 10 being formed with a slot at right-angles to its length, and arranged to embrace the other arm of the yoke when said plate is swung to locking position; said yoke being provided at its free ends with suitable tightening or :5 locking devices.
2. A scaffold securing device consisting of a yoke provided with a plate formed with an opening at one end, a slot at its other end, and a key-plate for guarding said slot; said yoke being provided at its free ends with suitable tightening and locking devices.
3. In a scaffold structure, a bar supported at one end by a hook eccentrically pivoted to a yoke, in combination with a device for se curing said bar to the scaffold, as shown and described.
In testimony whereof I affix my signature in presence of two witnesses.
JACOB L. LIGHTNER.
