ITED s'r PETER N. PETERSEN, OF NEW YORK, N. Y.
FORM FOR CONCRETE WALL CONSTRUCTION.
Application filed April 25, 1925. Serial No. 25,781.
The advantages and simplicity of the construction will be brought out in the following specification and illustrated in the ac companying drawings, forming a part thereof:
Referring to said drawings:
Fig. 1 is a side elevation,
. Fig. 2 is a sectional view, 011 a larger scale, taken on the line 2-2 of Fig. 1, and
Fig. 3 is a sectional detail view taken on the line33 of Fig. 2.
2 The reference numeral 5 denotes the longi tudinal mold boards, which, as illustrated, are arranged in two parallel rows. Pairs of upright supports '6 are placed on the outer sides of the mold boardsand at oppositely disposed sides thereof.
Pairs of members 7 are secured to the outer sides of the upright supports 6. These members 7 may be in the form of V cleats, or preferably in the form as in the drawings. The members 7 are secured in pairs to the upright supports 6 and are spaced apart slightly as indicated at 8 in Fig. 1.
Passing through the space 8 and extending from one pair of members 7 011 one side of the mold boards to the pair on the opposite side are tie members 9. The tie members 9 are preferably made of a continuous 7 piece of strong wire, the ends of which are twisted together at 10, thus forming a loop. The length of these looped tie members depends upon the width of the wall that-is to be built. The mold boards 5 may be notched out as indicated at 11 in Fig. 3 for the passage of the tie members 9 or the project beyond the members 7, thus forming eyes for the accommodation of anchorage pins 12. These anchorage pins are made of substantially heavy material, semicircular in cross section and are bent so as to form two legs 13 and 14, at approximately right angles to each other. The longer legs 13 of theanchorage pins pass through the looped. portions of the tie members and the flattened parts of the pins bear against the members 7 at opposite outer sides of the mold boards, so that, when the concrete is being poured the mold boards are rigidlyheld against the lateral expans1on due to the great pressure of the conj cr'ete. The shorter legs 14 of the anchorage 7 pins rest on the" top sides of the higher of the two members 7 so that in case the forms.
should loosen slightly before the concrete is poured there would be no probability of the pin dropping from its position. If thought necessary, ahole could be bored in the shorter leg 14 to accommodate a spike which could be driven into the upper of the horizontal members 7. This would main-' tain the pin firmly in position. Under ordinary circumstances this would not be re: quired, however.
After. the concrete has been poured and allowed to set the anchorage pins vare removed and the forms taken down. i The looped exposed ends of, the tie members sticking out beyond the finished wall are snipped off as closely as may be desired and the remainder of the tie member stays in the wall. The heavier longitudinal rein-'85. 'forcements could also be readily attached to of theinventionor the scope of the append r ed claim. 7
- What vI desire to claim as new is:
' Apparatus for construction of concrete walls, comprising two rows of longitudi- "nally extending mold boards, upright supports for the boards, pairs of horizontal boards secured to the upright supports,
boards, and anchorage pins flat at the side having two legs, one to pass through the ends of the loops and the other to rest on the horizontal boards on which it is prevented from turning and falling out by the flattened side abutting the sides of the horizontal boards.
