To all 'whom it may concern Be it known that l, HENRY Fouiner-il, a

citizen of the United StatesVresiding et;

Hazleton, in the county of ll'fucerne and State. of Pennsylvania, have invented cer` tain new and useful improvements in'oinbined vReinforces and Mold-Supports for i 'Concrete Structures; end I dodeclare the sary to brace the forms and in Which a- A ollowing'to be e full, clear, and exact description of the invention, suches 'Will enable ,others skilled in theart to which it 'ap-- pertains to make end use' the seine.'

llhis inventionrelates to e combined` rey ininimum quantity of lumber is required to construct it. v

This invention also comprehends details l o'f construction which, together with the features above specified, will'bebetter understood by reference to the accompanying drawings, in which l Figure l represents a transverse 'vertical section of a cement Wall embodying this invention and in which some of the mold boards have been removed showing the compl eted wall and others remaining in position during the setting:T ot the cement; Fig. 2`is a front elevation of a wall embodying" this improvement and showing some of the mold boards removed and others in operative position. Fig. 3 is a detail perspective view of a mold support constructed in accordance with this invention; Fig. l is a horizontal section showing a modified forni'of the invention; Fig. 5 is a detail perspective view of the combined anchor'and mold support employed -in the construction shown in Fir. 4. Fir.' 6 is a. detail perspective view of a slightly different torni of mold support provided with means for supporting a mold to i'orm an oliiset around the surface of the wall to be constructed.

In the embodiment of the shown in Figs. l and 2 o. plurality ot anchors l are employed for holding the molds or forms in operative position during the construction of the wall. Esch of these invention supports or anchors consists of a bar pref erably com osed' of soft steel, such as is ,known as ban`d iron and which is preterablyebout oneiiich wide byV onelsixteenth oi an inch thick, more or les wail to beconstructed and the molds to be f used. Each of thesedevices comprises a body portion 2 with prongs at its opposite l the length of, said bar conforming to the thickness of the ends to engage the upper edges o the lower moldboardsand the lower edges ot the upperfmold boards next above as is shown clearly in'Fig." The ends ot the bar ere sheared and each bent to form teur prongs 3', 4f, 5 end, the prongs 5 and G being spaced 'a' suitable distance from the ends to span the edges of the mold boards to which the anchor is to be applied.

The prongs 3 and 4: at the terminal of each bar are preferably termed by shearing" the bar in the center and bending` one-liali thereof laterally in one direction and the other half in the opposite direction in position to engage and hold the upper edge" of one board and the lower edge of the adacent board against outward movement.

f The

prongs

5 and 6 are formed by striking out tongues from opposite edges of the bar and bending one in one direction and the other in the opposite direction thereby :forming the prongs which hold the mold boardsrom inward movement. The cut ting ot these tongues which form 'the prongs 5 and G i'ormsI a weakened shank or neck 7 `for a purpose to be hereinafter described. Prongs 8' are also formed by striking; out tongues from opposite edges or' the bar at points spaced inward from the noch 7 and bending them inwardly to form pockets tor a. reinforcing bar or rod 9 when such is employed as is shown clearly in Fig. 1. A l

In the use of this improved anchor and mold support a'layer of concrete or cement is first disposed in aconcavity such as a ditch upon which'the wall is to be erected. This layer is placed without forms and is accurately leveled, and the wall is erected thereon in the following manner: rlChe nnchors l are placed on this foundation `sufh *ciently close, about two feet apart more or less, to, engage the lower edge of the mold I which may be of metal, wooden boards boards lined with metal of any desired design. .Then o s'uiicient number o' anchors this is done these mold boards may be held perfectly plumV by forcing blocks orl boards 11 at intervals between the mold boards to force said boards tightly against the prongs 3 land 4C. The molds so formed may be arranged in perfect alinement and is ready to receive the concrete or cement. The blocks or boards 11 between the mold boards 10 are removed as soon as the molds have been lilled in lwith the concrete which will hold the mold boards in position without the use of any additional boards or blocks. When this first course Iof the wall has been completed the second boards of the mold are laced in position and the prongs and 5 at the ends of the anchor will engage the opposite faces of the lower edges thereof. and hold these boards in alinement with the boards, below with which the prongs fiand 6 are engaged. Similar' anchors are then engaged with the upper edges of the unfilled boards of the mold with the prongs l and 6 thereof engaging the opposite faces of said upper edge and blocks 11 may be arranged between said-boards to force them against the outer prongs of the anchors if it is found to be necessary and said boards are thereby held irmand ready to receive the second course of cement. After these boards have been filled the blocks 11 are removed as above described and other boards may be added in the same manner until the wall is of the desired height. When the lower courses have become sufficiently hard the mold boards may be removed therefrom and used again on the upper courses. To remove these mold boards the outer prongs l are bent outwardly," which may be done with any suitable tool, above `the upper edges of the lower mold boards with which they are engaged and these boards 10 may then be easily withdrawn for use on succeeding courses, the withdrawal thereof also bending theprongs 3 of the anchor below, which engages the lower edge thereof, downwardly as is shown clearly in Fig. 1. .After removing the mold boards 10 the outer portions of the anchors are' twisted thereby breaking them off at the necks 7 which are disposed within the concrete wall not less than one-half inch from the outer face thereof. By forming these weakened necks the ouler ends of the anchors may be readily bro ren by twisting them back and forth oncev twice and when the protruding board supporting ends have been removed the recesses left in the outer face ofthe wall are pointed up or cemented over producing a perfectly smooth outer face and completely covering the anchor and thus prevering rust stains on the surface of the wa During the construction of the wall before the cement is filled into the molds if it is desired to strengthen the walls longituprong 12 is bent downwardly it will engage Y the outer face of the` upper edge of the mold board and corresponding anchor disposed at the lower edge of said mold board has the tongue 12 extended upwardly to hold the board 10 in position to form the oii'set as is shown clearly in Fig. l.

In the form shown in Figs. 4 and 5 a wall is shown constructed with concavities or spaces between one face thereof and the plastering 13. The boards 14 employed in forming the inner face of the wall shown in .these figures are arranged vertically the entire height from door to ceiling thereby forming a vertical joint between the mold board on the inside of the wall and horizontal joints in the mold boards forming the outer surface of the wall. (See 14 and 15 of Fig. 4).' These mold boards 11i are preferably provided with wooden studs or bars 16 having nails 17 driven therein from the inside and cast in the concrete when poured to hold said studsA in place and to which the lathing is attached on which the plaster walls 13 are mounted. The form of anchor employed in connection with this style of wall is shown in Fig. 5 in which one end thereof is constructed similarly to the anchor described and shown in Figs. 1 and 2, the other end of said anchor is twisted to dispose the prongs 3', 4c', 5 and 6 laterally instead of vertically as in the other figures to adapt these prongs for engaging the vertical mold board 14. The twisting, however, is not confined to the neck but it may be done at any point de sired.
