Fi re? is a detail perspective view 'of-the spacer' forming a salient part of the pres ent Figure 9 is a fragmentary view similar to v Figure 3 einbodyinga modification of the tie. element or spacersupportingmeansf In the drawings,awherein for the purpose of illustration is shown the preferred embodiment" of my invention rthe numerals 1' and ,Q 'designate generally the vertically ,dis posed parallel spaced walls ofamold or form zbetweeniwhich the plastic mat'eri l poured. in'order to form a concrete wall. Each form .wallincludes" a series of boards or metal sections 3;that are disposed'in edge'to edge rela face' of each section or board at it-hef respec tive-jends thereof. As many of these jwall sectionsfor boards may-be employed asfis necessary, depending upon the height i and A series of tie elements, consistin of metallic blades such as shown at in igure 8, are disposed transversely of the form, the ends of the blades being disposed between the adjacent edges of abutting pairs of form boards or sections, and the outer extremities 0f the tie elements or blades projecting beyond the outer faces of said forms. ikn opening 6 is formed in each end portion of each blade 5, and also formedinthe ends of each blade inward-l the in receiving ioles 7, the purpose of whic will be presently described.
A channel-shaped spacer member 8, that is preferably formed of corrugated metal, is removably fitted over and rests upon the ed of the intermediate portion of can tiee exncnt or blade 5, and each spacer is rovided with laterallydisposed flanges 9.
e ends of each s acer are notched as indicated at 10 (see i we 7) and thelength of the Spacer mem ers depends upon the thickness of the concrete wall that is to be molded. The ends of the spacer members are adapted to abut against the inner faces of the form walls 1 and 2 as clearly shown in Figure, 3. I s
A pin 11 is disposed through each pin hole 7 formed in each of the blades 5 and the projecting ends of the pins extend through the notcheslO formed in the ends of the respective channel-shaped spacers 8. These pins also engage with the inner faces of the form walls for the purpose of preventing the form like portion tapering gradually from its central portion toward its respective ends and inwardly directed lugs 15 bein formed on the extremitiesthereof. Rein orcing webs 16 connect the outer faces of the hollow and the ends ofthe plate-likeportion as also su%gcsted very clearly in' Figure 6., ach" clamping. member is disposed across the outer edges ofthe abutting flanges et with the lugs 15-en ging withthe side faces ofi the flanges, QIIE IDuOI'dBI' to secure I the clamping -member 12 from displacement rs 17am provided on the innerfaeeofthe fits-like rtion 14,"said spurs being adapt- Oil to lntotheonter faces 0t theabuttin g v a; portions t when woodenform sections are. used The clamping members are-pref erably locetedso as to receive the projecting ends of the blades 5 and the-projectingends of the blades loosely extend into the hollow of the openings 6' are T threaded on the projectin body portions of the respective clamping members as clearly shown in Figure 3.
A threaded shank 18 is loosel disposed through central aperture provi ed in the outer end of each hollow body 13, and formed on the inner end of each shank is a hook member 19, said hook member being slightly oil'- set. It will be noted upon referring to Figure 5 that the hook tapers gradually toward its point and is adapted to have pivotal engagement in the opening 6 formed in the adacent end of the blade 5. Due to the swing- -'-1ng'movement allowed the blade 5 relative to the elampin members, the clamping member at onesi eof'the form may be placed higherthan that at the opposite side, when found necessary or desirable. ,A nut 20 is I end of each shank 18 for engagement with the outer end of the adjacent clamp body, and by turning the nuts in one directionv the clamps can bedrawn in- .wardly so as to adjust the walls of the form toward each other and bring them into engagement with the pins 11 and the ends of the channel-shaped spacers 8. If desired, the pinsll may be used and the spacers 8 eliminated. V
, Suitable braces21 may be provided in association with the mold, and in Figure 3.there is clearly disclosed the manner in which these braces are connected with the mold; T he braces are disposed at an inclination and the up rends thereof are angularly directed an formed with openings to accommodate the threadedshankgsaid angularly directed ends 22 ofthe braces being disposed against the outer ends of the'bodies of the respective clamping members on one sideof the mold, and-the adjacentnutsQO holding the upper ends of the braces in position. v The lower endsof these inclined braces are also angularly directed as indicated at 23 and are formed with openings to accommodate the stakes 24 that are driven into-the ground. Whentheparts: are arranged as shown in Figure 3, the form is assembled so that concrete may be poured between the walls thereof, and after the plastic material haeset, the form walls are removed; along with "the clamps It might be well at this time to state that in order to ascertain whether or'not the hook members are properly engaged with the apertured ends of the" blades, each hollow body is' formed'with sight openings 25- .In order'to prevent the'adjusting bolts from turning and breaking loose from the associated blade 5, a tool maybe inserted-in the openings 25, when found necessary.
:Aftesthe walls of the form havebeen removed, theproiecting ends of the blades may be twisted ofii oriotherwise separated from theintermediate portionsof the blade that remains within the concrete along with the cor- 'rugated spacers 8. Thepins'll mafy'then alao be removed.
In Figure 9 of the drawings, I have shown a modification of the spacer supporting means wherein the same constitutes a looped wire member 26 that funct-ionsin the same 'manner'as the metallic blades 5, the hooks being disposed through the looped ends of said wire member. Then a nut is moved to the innermost threaded portion of the shank, a further rotation of the nut will cause turning of said shank so that the adjacent end portion of the looped wire will be twisted as shown invFigure 9 to insure bringing of the walls of theform tightly against the ends of the adjacent spacer 8.
A form tie of this character can be readily and easily assembled or disassembled and by arrangement of the parts in the manner as proposed, access'thereto may be had from'the outside of the form sothat the necessary adjustments can be made without difficulty. Furthermore a device of this character will at all times be strong, durable, positive and efficient in carrying out the purposes for which it is designed. i
While I have shown the preferred embodiment of myinvention, it is to be understood that minor changes in the slze, shape and arrangement of parts may be resorted to with out departing from the spirit of the invention or the scope of the appended claims WVhat is claimed is: I I
