FORM TIE WIRE TIGHTENER AND FASTENER v 7 Alexander T. Pryne, Los Angeles, Calif. Application April 20, 1938, Serial No. 203,217

, 8 Claims.

My invention relates generally to concrete forms and more particularly to a device for tightening and securing the tie wires that pass through the walls of the form.

5- The principal objects of my invention, are to generally improve upon and simplify the construction of the existing forms of concrete form tie wire tightening and anchoring devices; further, to provide a device of the character re- 102 ferred to that issimple in construction, strong and durable, composed of a minimum number of parts, and which may be conveniently applied to the wall of .a concrete form and readily manipulated to tighten the tie wires and twist 1 the ends together, so as to hold the walls of the form firmly in proper spaced relation and further, to provide simple means for mounting the main body portion of the device on the form so that said body portion may be easily and conveniently rotated to draw the tie wires taut and retain the same in such condition.

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts that will be hereinafter more fully described and claimed and illustrated in the accompanying drawing in which: I

Fig. 1 is a front elevational view of a tie wire tightening and securing device constructed in i: accordance with my invention.

Fig. 2 is a side elevational view of the device in position upon the wall of a concrete form.

Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 1.

Fig. 4 is a plan view of the base member of the device before the arms thereof are bent around the edge of the rotating member of the device.

Fig. 5 is a horizontal section showing the wire 0 receiving member mounted for rotation upon a nail that is driven into the form.

Fig. 6 is an elevational view of a combined wrench and nail-set that is utilized in connection with my improved device.

5 Fig. 7 is a plan view of the end of the tool and showing the nail-set.

Referring by numerals to the accompanying drawing, I0 designates a disc that is preferably formed from sheet metal of proper thickness 0 and formed integral with the edge of said disc is a plurality of outwardly projecting arms N,

there preferably beingfour of these arms and the same disposed ninety degrees apart.

Struck from the material forming the disc,

5 are two or more prongs l2 which are bent at right angles to the plane occupied by the disc and said prongs being driven into the wall of the form to which the device is applied, thereby firmly anchoring the base member I0.

Mounted to rotate on the 'face of the disc I0, 5" is a disc I3 preferably of cast metal and which constitutes the base of the rotary wire receiving member of the device and to retain this member for rotation on the disc I0, the outer por- V tions of the arms II are bent around the edges 10 of disc l3 to form retaining hooks I4.

Disc I3 is slightly larger in diameter than disc Ill and formed in that portion of the disc l3 that projects beyond the edge of disc I0, is a series of notches I5, any one or more of which may receive a nail that is driven into the wall to which the device is applied for the purpose of holding the rotary member of the device against reverse rotation after it has been rotated to draw the tie wires taut and to anchor the ends of said tie wires. The head of a nail that is driven through one of the notches l5 into the wall of the form to hold the disc l3 against rotation is illustrated in Fig. 1.

Formed integralwith and projecting outwardly from the central portion of the rotary disc I3, is a stud l6 preferably of hexagonal contour in order to receive a wrench or like tool utilized in rotating the disc l3 and stud l6 and formed in this stud is an axial bore or chamber ll, the lower end of which communicates with an aperture l8 that is formed through the center of disc I 3.. I

The wall of stud l6 that surrounds the bore I1 is provided with oppositely arranged longitudinally disposed slots l9 that gradually taper toward their inner ends. This tapering of the slots l9 enables the latter to receive wires of diiTerent diameters and when the wires are pressed into said slots toward the lower ends of the latter, the wires have direct contact with both edges of both slots.

In Figs. 6 and 7 I have illustrated a tool particularly designed for use in connection with my improved tie wire tightening and anchoring device, said tool being preferably cast in a single piece and comprising an arm 20 that functions as a handle and one end of said arm being enlarged as designated by 2|.

Formed in the enlarged end 2| of the tool, is a pair of parallel slots 23 that are adapted to receive those portions of the stud I6 to the sides of the slots l9 and the bar 24 of metal that is disposed between the slots 23 enters the slots l9 when the tool is applied to the stud l6 for ll the purpose of rotating the same on the base III. In Fig. 6 the stud I6 is shown by dotted lines.

Projecting laterally from the end of the arm 20 opposite head 2|, is a short cylindrical stud 24 that functions as a nail-set and which is used when a nail is driven through aperture l8 into the wall of the form so as to provide an axis upon which disc I3 and stud l6 may rotate.

In Figs. 1, 2 and 3 the rotary member of the device comprising the disc l3 and stud I6 is shown mounted for rotation upon the base 10 and in Fig. 5 the rotary member comprising base In and stud I6 is shown mounted for rotation on a nail that is driven into the wall of the form.

In the use of my improved tie wire tightening and anchoring device, those portions of the tie wire that extend beyond the wall of the form to which the device is appliedare brought to the stud l6 and said wires are pressed into the lower ends of the slots 19. The end portions of the wires that project beyond the slots l9 are then bent anti-clockwise partially around the exterior of' stud IE, after which the slotted head of the tool is applied to the outer portion of stud l6 and said tool is moved clockwise, thus imparting rotary motion to disc [3 and stud I6.

Such action winds portions of the tie wire on to the stud l6 and when the wire has been drawn to the desired degree of tautness a nail is driven through one of the notches l5 into the form on which the device is positioned, thus holding the rotary member of the device against reverse rotation and consequently anchoring the end portions of the tie wire securely to said device.

Where the rotary member of the device comprising disc l3 and stud l6 are used Without the base comprising disc l0 and arms ll, said rotary member is mounted for rotation on a nail that is driven through aperture I81 into the wall of the form and the driving of such nail is effected through the use of the nail-set 24 which readily enters bore I! in the rotary member.

Thus it will be seen that I have provided a concrete form tie wire tightening and anchoring device that is relatively simple in construction, inexpensive of manufacture and very efiective in performing the functions for which it is intended.

It will be understood that minor changes in the size, form and construction of the various parts of my improved concrete form tie wire tightener and fastener, may be made and substituted for those herein shown and described, without departing from the spirit of my invention, the scope of which is set forth in the appended claims.
