Description

W. L. GLIDDEN.
CLAMP.
APPLICATION FILED JAN. 14. 1909.
rammed Feb. 1,1910.
' :3 mm yutoz,
fez
To all whom 'it may concern:
dmll.
Be it known that I, WRIGIrrL. GLIDDEN,
. a citizen of the United States, residing at Brooklyn, in the county "of Kings and State of New York, have invented new and useful Improvements in Clamps,'of which the following is a specification.
This invention relates to clamps, the ebject of the invention being .to provide a clamp especially adapted for fastening together ladders or ladder sections, braces,' beams. uprights and other elements of a scaffold for the purpose of enabling a strong, safe and thoroughly braced structure to bequickly erected or set up and taken down, the clamp also embodying means whereby the several parts or members thereof are maintained in the proper working alinement and relation to each other while adj usting the-clamp, as a whole, to the structure in connection with which it is to be ilsed.
\Vith the above and other objects in,view,
v the nature of which will more fully appear as the description roceeds, the invention consists in the nove construction, combinatlon and arran ement of parts as herein fullv described, illustrated and claimed.
The accompanying drawing represents a perspective v ew of a complete clamp embodying the'present invention, showing the same applied to a round. object such' as a ladder rung and a beam of rectangular shape in cross section. s I e The clamp contemplated in this invention comprises essentially a hook-shaped jaw 12 having a threaded shank 11, the exact shape of the hook-shaped jaw 12 being immaterial as long as it is so shaped as to adapt it to embrace a portion of a laddenor beam or upright, as the case may be. Mounted on the threaded shank 12 is an- 7 other hook-shaped jaw 13 which is provided with a hub or sleeve portion 17 said hub extending considerably to one side of the body of the'jaw 13 to form a bearing of considerable length through which. the shank 11 passes, the hub 17 preventing the hook-shaped jaw .13 from dipping or canting or. binding on the shank 11. I
16 designates a clamp. nut which backs up the hook-shaped jaw 13 and bears against g the projectinghub 17 thereof.
Located between the two hook-shaped.
v Specification of Letters Patent.
jaws hereina bove described is an intermelP'atiented Feb. ll, Twi l).
diate double jaw or triction plate 14 adapted to be interposed between the two objects 15 and 18 to be held by the clamp. Thisintermediate double jaw or friction plate may be providedlwith suitable positioning lugs 19 and 9.0 to bear against the adjacent tapes of the objects 15 and 18, if desired, so as to properly position said parts relatively to the clamp andto each other, this, however, being immaterial. "An essential feature of the intermediate double jaw or friction plate resides in the hub portion 21 of said plate, said portion being formed integrally with the plate 14L and projecting'a substantial distance from o e face and adjacent to one edge of said plate to form a long bearing for the plate on the shank, the said hub portion being adapted to be slid along the shank'll to any point which will permit the plate 14 to lie between. and in clamped contact with the two objects simultaneously held by the clamp, asv H'WllOlB.
After the clamp has been associated with the two. objects to beheld together thereby, the nut 16 is screwed down tightly again t the hub 17 of the jaw 13, thereby firmly securing each and all of the jaws of the clamp .111 engagement with the objects held thereby.
It will be observed that by reason of the shape of the-hook-shaped jaws and "the in- I termcdiate jaw or plate, the objects to be clamped are capable of lateral introduction to and removal from the clamp elementsof the device whichg reatly facilitates the" work of setting up and taking down-a structure, such as a scaffold.
A .scaitold clamp comprising ahooksha'ped'jaw having a threaded shank, a second hook-shaped jawhavin a substantial hub'portion slidable on sai shank, a nut on the'shank to bear against the last-named jaw, and an intermediate double jaw orfric tion plate located betweenQthe two hookshaped jaws and having a hub portion at one side edge and projecting a substantial distance from oneface of the plate and slidable on the shank.
In testimony whereof- I aiiix my signature in presence of two witnesses.
