wiztmeooao pert o the plank JOHN H. SULLIVAN, OF GEAND RAPIDS, MICHIGAN.


Specification of Letters Patent.

Patented Ell ot. ll, 191W.

Application filed February 24, 1910f Serial No. 5%,716.

To all whom it may concern:

'Be it known that I, JOHN H. SULLIVAN, a

. I citizen of the United States, residingat' Grand Rapids, in the county of Kent and State of lllichigan, have invented certain ncv and useful lmprovenients 1r. lilold-Tics; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. p

This invention relates to tie Wires for molds and is especiall adapted for use in molds for concrete walls.

In the erection of concrete building Walls, ibis eustoniary to employ molds composed of planks or boards arranged in vertical edgewise relation and having their meeting edges temporarily connected by means of "fastening members or clips, the clips on opposite sides of the mold being connected by rods or bolts. These bolts While thoroughly efficient for uniting the boards points between their ends have been found in practies to be objectionable to the extent that when said bolts are used, it is necessary to form notches in the lower edge of the plank which were set immediately on the upper holder and over the bolt there? y rendering the planks unfit for other use; p

Th s in has for object to prc ride e form oi? tie rod which may be conveniently employed to connecting the boards on the opposite sides of the mold nd. which is cheaper and quicker to hnndle'und the use of which, the necessity of niutilating the planks LOIH') the mold is We *vi ith this snt otl s invention consists certain novel is. arcs of coustruc'on, combination and arrena merit of parts, will more fully scribed and particularly pointed out in the appended. claims.

In the accompanying 1 ra'wings figure 1 is a perspective View of a portion of a mold "ed tieepplied and Fig. on tn h the mold e in side clan ion.

showing this imprc 2 is a traus.-- shown) the In. the "nbodiz nent ilhistretei. plaid: holders l 9 are shown ounteo. on the upper of the side These holdeiz are connected by means of a piece of Wi ly. on number 12 which 15 1 toot more or apertures in t is less longer than the extreme Width of the mold. This Wire 3 is extended through the holes, as 4:, in the plank holders and one end thereof projects over the outer face of the plank holder about four or five inches and is turned down flush with the outside face I of the plankormold side directly under the aperture in thep'lank holder and is prefer ably struck a light blowto form a bond 3' to confine it more closely to the face of the plank. About three inches, more or less, below the upper edge of the plank, a'small three-fourths of an inch staple is arranged astride the Wire and forced into the plank. The terminal of this end of the Wire is then bent back over the staple, thereby securely fastening it against accidental Withdrawal. The other end of the Wire 3 is then drawn taut and is the mold in a manner similar to that above (lQSCllbGd. The formation of a sharp angle directly below the hole in the plank holder causes the lateral pressure of the concrete between the planks to be exerted between these two points and there is-no strain or tension on the staple.

When it is desired to remove the mold from the Wall being constructed the wire 3 may be cut of? flush with the outer faces of the Well and either left to form a rein forcing; member for the concrete or it may be Withdrawn While the wall green if desired. This device for securing together the mold sections is Very cheap to manufacture and may be very quickly applied.

From the forceoin descriotion taken a e: l 7

Having apertures therein, a WlIS extended through the apertur in Said holders Withthe ends thereof projecting beyond the holders end bent downwardly holders at e sharp angle directly below the holders and detachable means for securing seid ends to the-mold.

E5. The combination with a mold haying secured to the "opposite side of around said spaced side Walls, plank holders arranged on the upper edge of said Walls and provided with apertures extending transversely therethrough, a wire extending through the apertures in said holders )osite ends beyond said holders, saidends ing bent outwardly around the holder into close contact with the side walls of the mold, staples for securing said ends to the sidewalls of the mold, the terminals of said ends being bent upwardly around said staples.

3. The process of forming a mold for a concrete construction consisting of arrang ing two portions or planks edgewise and spacing them lateral yfrom each other,

and projecting at op erases per edges below said holders into engagement with the outer faces of the to the mold and of said ends upwardly.

In testiinonywhereof I have hereunto set my hand in presence of two subscribing Witnesses.
