COLUMN-FORM, SHORE, AND SCAFFOLD CLAMP.
Specification of Letters Patent. Patented N 30, 1920.
Application filed April 14, 1919. Serial No. 289,910.
To all w hem it may concern: Y Be it known that l, NORMAN DoUoLAs, citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Column- Form, Shore, and Scaii'old Clamps; and I do d clare the following to be a full, clear, and exact description or the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention has for its object to provide an extremely simple and inexpensive, easily applied, and reliable clamp for use principally in connection with concrete structures, for securing ax battens around column forms, for constructing scaffolds, and for connecting the upper and lower sections of shores, the device being of such construction to permit it to be easily stamped from a single length of channel iron or steel, or other suitable metal.
llith the foregoing in view, the invention resides in the novel clamp hereinafter fully described and claimed, reference being made to the accompanying drawings.
Figure 1 is a horizontal section of a column form showing eight oi the clamps in use for forming a collar of l-Xl battens around said form.
Fig. 2 is a side elevation of the form,
collar and clamps illustrated in Fig. 1.
liigs. 3 and l are respectively a vertical section and a side elevation showing one mannerin which the clamp may be used in the construction of scafi olds.
Fig. 5 is a horizontal section on the plane.
of channel iron or steel, said length being bent between its ends on a transverse line 2, to provide relatively short and long arms and a disposed at an obtuse angle to each other. The flanges 5 of the length of angle iron or steel, serve to reinforce the arms 3 and 4: and the body portion ofthe metal is bent laterally away from the flanges 5 to provide a hookflange 6 atthe outer end of the arm 3, this flange being provided with holes 7 to receive nails, screws or the like. The metal between the'fianges 5 of the arm 4 is cut .awa I to jiovicle a rectan ular ooening S extending from the line 2 to approximately the outer end of sand arm 4%, and
both endwalls of said opening are beveled to provide sharp edges 9 adapted to b1te 'scuring the disclosure by a multiplicity of reference characters. Figs. 1 and 2 show a column form 10 and a. collar around said form formed of battens 11 and 12, the battens 11 resting on the battens 12 with their ends crossing the same at the corners of the form. Eight of the clamps are necessary for securing the battens 11 and 12 together, two clamps being disposed on each bar 12 and two on each bar 11 as illustrated clearly in Figs. 1 and 2, and wedges 13 are drivenbetween the short arms of the clamps and the battens to clamp the latter tightly against the column form 10. .Slippage' of the long arms of the clamps on the several battens is prevented by the biting edges 9 above referred to.
In the constructing oi scaffolds (see Figs. 3, a and 5) the long arm o1 the clamp may be. mounted on a vertical post 14 and the short arm thereof will then support a horizontal beam 15, and if desired nails or the like 16 may be driven through the openings 7 to hold said beam in place, but slip page of the clamps on the post l l is prevented by the bitingedges 9.
Figs. 6, 7 and 8 disclose the manner of using the clamp in the construction of shores. The upper and lower vertical sections 17 and 18 respectively, are slidable one upon the other, the lower end of the section 17 rests on a. clamp C mounted on the section 18 and said section 17 passes through the long arm of another clamp whose short arm rests on the upper end of said section 18. The edges 9 prevent slippage oi the clamps with respect to the sections 17 and 18 and prevent any possibility of lateral tilting of said sections. Nails 19 are preferably driven through the openings 7 as shown.
In the foregoing, I have described three uses of the invention but it will of course be understood that it may be employed wherever applicable and may be used in any of the numerous ways in which it will perform the intended functions. Furthermore, although I have illustrated and described the device as formed of a single length or" channel bar, it will be obvious that it might be otherwise constructed if desired. However,
since probably the best results are obtain able from tl exact construction disclosed, it is preferably followed.
I claim:
A clampof the class described comprising a single length of channel bar having its two end portions disposed at an obtuse angle to each other to form beam engaging arms, the side flanges of said bar serving to reinforce said arms, one of said arms having a rectangular opening extending from a point adjacent its outer end to approximately the line of juncture of the two arms, the inner and outer end walls of said opening having biting edges, the body portion of said bar at the outer end of the other arm being bent laterally at substantially right angles to the other and provided with an opening to receive a nail or other 'lastener.
In testimony whereof I have hereunto set my hand.
NORMAN DOUGLAS.
