' invention relates toforms for concrete 7 7 structures and more particularly to a form lor wall tie for trans'versely connecting the walls ofaconclrete Itis customary in thevconstruction of' concrete'form's toprovide side walls of boards attached to uprights'oi' studding; 'Theupoppositely, disposed and are interconnected such casethe'transverse ties do not-per sedethe form-walls; I It is usual such'constru'ction to employ Wooden spacers which are interposed at intervals between the form walls and whichxmust be removed as the concrete is formed. 9 I f t p The present form of tie is pre-iormedin predetermined sizes inv accordance with the thickness'o'f the concrete wall or the spacing of theform walls.

In its preferred form the presenttie comprises a "single strand of wire having at, one "end short cross arm attachedthereto and at itsopposite end in predetermined spaced such short cross arms spaced one from the other a distance substantlally equal to the thiekn ess of the boards forming theside-wall' of the form, In applying the ties the end hav ing the single cross 'arm isjpassed between successive form b oards adjaeent to an up right strut or studiding-withthe shortcross arm atthe inner sid'eort the form wall.

Consequently the struts or studding may be The suc- I cessive ties are arranged in reverse relation, that is to say, Whereas the end of the tie having the single cross armis passed about the offset infrelation with each other strut or studding at oneside of the form and the double cross arms in the opposite end of tudinally of the form, will be arr anged with its single cross arm engaging the last men tioned wall of the form and extended about a strut on the side ofthe form with which the double cross arm was engaged and theend of the. tie straddle the form board of the opposite wall inthe next succeeding'tie, longithe secondtie,'carryingthe spaced double cross arms will be engaged with the'opposite form wall Corresponding tothat contig uous to the strut or studding with which'the single cross arm end of the engaged.

and unlikely to get out of shape or alignment.

A further object of the invention is to providefan improved form of tie which may be easily and quickly applied and which will predetermine the spacing of the form walls. A further object of the invention is to provide a form tie'whieh will tend to hold the form boards in their adjustedposition thus reduce to a'minimum the use 0 studding.

At the opposite manner as the cross arm l of the described construction-L Instead of interconnecting su'ch nehor; members :9 and '12 by an intermediatestrand 8, such anchor members may 'fiap*strip of material 15: shownin Fig. 6. In such case the strip 15 is twisted at;16 to enable it to pass about the supporting struts I or stu'ddingQ. Theffingers 13 ando l lyat'one endofthe strip engage'theinner side ofthe form wall while the spaced lingers 1'0 and-11 at the opposite end of the strip 15 straddle succeeding boards of the opposite wall of the form.- a I In lieu of the spaced cross armsor fingers heieto'foredescribed, thetie or spacerstrands maybeprovided with spaced knots 17 as ill lustratcd in Fig. 7. In this instance the tie s strand 3 is shown 'as: provided with a single knot at one end, corresponding to the cross jarm l andserving alike purpose, While at I ect matter hereof is engageablewithone wall and about the studding or support and is engageable with the opposite wall independent 01 a studding or upright, there are conditions inetj'in buildingconstruction wherein it may be desirable to employ oppos tely disposed uprights orstuddings. In such" case, a tie a strand 3 having a single cross arm 4 at each end as illustrated in'Fig. 8 may be employed; In such case, a bight is formed at each end of the tie strand Sto embrace the oppositely disposed studding oruprights W In other words, in lieu oI' -the double anchor fingers 5 and 6, which are intendedforengagement with'the form boards intermediate succeeding studding orl-uprights, the single-cross arm 4 twithits studding engaging bight is dupliicated at the opposite end of the tie.

' For thoseconditions where itis desired to ding, or atpoints Whore uprights or studding,

brace a form intermediate uprights or studare not available, it is quite practical to duplicats the spacedanchor fnigers or'cross arms and 6 at each end ofthe tie strand as shown i 9. By providing such cross arms or anchor lingers 5 and6 in spaced pairs at each cndof thestrand 3, such strandmay be uti-' li'zed tobrace and tie together the sidewalls of the concrete form wholly lndependent of supporting struts-orstudding. The connecting strands 3 and 15 being comparatively .thin are easilyjembeddedin themargms of the form boards by the Weight of the succeeding boards above or by a hammer blow. Thus theexisten'ce of intervening zcrevices or cracks sufiiciently large to permit leakage of the concrete is entirely avoided. The use of thepresent form of tie insures the proper and accurate spacing 'ofithe form Walls and anchors them one to another to preventbulging or collapseiunder the pressure of the concrete there within. Moreover, by use ofthe present form o-iftie and spacer member the use ofnails is almost entirely obviated. The

top course'of boards is preferably nailed to prevent the "boards from floating up or ris lug-as concrete is poured nto the form. iVhrle, 1t des1red,'the boards may be nailed to the studding or uprights in the usual manner, it has been found in practice'that the present tie is sufiicient under all ordinary circumstances and conditions to securethe form boards in place. Notonly does the. use of these ties contribute to the strength of the form and facilitatethe rapidity with which a form may be constructed, but they also very materially facilitate the removal of the forn'ia'fter the concrete hassct; This isdone by cutting the bight of the Wire strand passing about the studding or uprightson one side oi thewall and by cutting or. knockingjofl' the anchor fingers 6 at the opposite side of the wall leaving the intermediate tie strand 3 embedded in the body of concrete.

While the present tie is primarilyintended for use in securing and bracing concrete forms itwill also be found useful in securing crating, bracing and reinforcing large shipping boxes, for racking materials or for bracingparts of buildings Obviously, thetie member may be made in any lengthand of increased strength to accommodate it to various conditions of use. I a From the above description it will be apparent that there is thus provided a construction of the character described possessing the particular features of advantage before enumerated as desirable bntwhich obviously is susceptible of modification, in its form, proportions, and arrangement of parts, without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention is described in languagewmoro or less specific as to structural features, it is to beunderstood that the invention is not limited to the specific details shown, but that the meansand construction herein disclosed comprise the preferred form oiiseveral mod es ofputting the invention into eil'ect, and the invention is therefore claimed inany of its forms or modifications within the legitimate and valid scope of the, appended claims.
