TIE STRAP Filed July 1. 1929 DIV/'71? SUMMERS 1n venlor A tlorney Patented Aug. .1,.. 19 3 3 1320.607 TIE s'raAr Omar Summers, Seattle, Wash., assignor of onehalf to Roman Yesse, Seattle, Wash. Application July 1, 1929. Serial No. 375,003

2 Claims. (01. 25 131) My present invention relates toan improved tiestrap for use in connection with the erection of concrete and similar building walls. The tie strap of my invention is designed for use not only in bracing and tieing or joining the pairs of walls which provide the form or mold in which the building wall is erected, but they also I perform the functions of gages in properly spacing the; walls of the mold to facilitate theconstruction of the mold.

Means are provided whereby the tie straps may readily be assembled and attached to the opposite walls of the form, and after the concrete wall sets and the form-walls have been removed, the. projecting ends of the tie straps may either be used for anchoring means of other building elements, or these ends may readily be broken oil flush with the facesof the concrete Wall. 0 e

The invention consists in certain novelfeatures of construction and combinations and arrangements of parts as will hereinafter be more fully set forth and claimed. In the accompanying drawing I have illustrated one complete example of the physical embodiment of my invention, and a slightly modified type of as strap, wherein theparts are combined and arranged according to the best mode I: have thus far devised for the practical application of the principles of my invention.

Figure 1 is a perspective view of onelof the metal tie straps-embodying my invention. Figure 2 is a perspective view of a portion of a form for concrete walls showing the use of the i tie straps. Figure'3 is a vertical sectional detail straps. Figured is a sectional detail view at line 44 of Figure Bshowing the use of a modifled type, of strap. Figure 5 is a perspective kerfs K in their edges. The usual studding S is employed at the exterior faces of the walls of the mold or form, and gage nails N and fastening nails N are also'utilized in the erection of the form for the concrete building wallJj The preferred type of tie strap used in retaining and bracing the two Walls of the form, is indicated by the numeral 1 as a light steel or iron strap which is fashioned at one sideof its .ing' nails N are used and groove center with a plurality or sets of holes 2' anal I, at the other side of its center with another series of holes 3; Near therespective ends of the strap elongated holes or slots 4 are provided; the selected holes 2 and 3. being for the recep tion of gage nails N and thes'lots'4 forgth'e reception of the fastening nails Nq The two series of holes 2 andB-are gage. holes f and are used with thenails N for properlyspac-L I b 65 ing the walls A and B of the form. ThusIfor instanceQthe 'innermost'holes' of the two series maybe ten inches apart and the two outermost holes of the two series may be twelve inches apart, and a selected hole of each series is used to provide the desired spacing of the two walls oftheiorm.

In Figures 4 and 5, the tiestrapS is fashioned with gage lugs 6 which maybe substitutedv .for gage holes 2, 3,1 or some of ,the gage lugs may beused with the gage holes in the same tie'strap. i j.

As shown inthe drawing, the tie straps are mold boards A and B and the gage nails N are passed throughthe selected.holes"-2 and 3 to properly space the walls of the mold; The ends of the strapsof. courseproject laterally of the mold walls and these ends are attached to the studding S by the nails N. 'By the use of the nallyof the strap thus securing a more effective deposited vvin the k erfs K offlthe wall-boards or anchor for:th'e ends of the straps than would the nails afford if driven at rightanglesjto the strap. The walls of. the mold are. thus tied view of part of the form. showing the use of the,

between the studdingan'd the gage nails, and the walls are retained'at the desired and required distance apart.

InFigure ithe gage lugs abut against the innerfaces of the mold walls A and B and take the places of the gage nailsNybut thefastenthe studding. V

I As indicated in Figure tached at opposite sides of the studding," that is, the tie strapffor one pair of boards A, B is strap for the adjoining pair of boards is nailed ,tothe far side of the studding, In this manner '2 the straps are atto secure the straps to nailedto the studding at the near side, and the the wall is poured and outward pressure is exerted against thewall boards of the mold, and

any tendency of the studding to twist or turn is eliminated.

nails N' are extracted and the studding and mold boards are removed, leaving the tie straps in the concrete wall with their ends projecting. These projecting ends may be broken off flush with the face of the wall, or they may be used as anchoring means for other parts of the wall, as for instance a brick face for the concrete wall.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A tie strap for use with wooden concrete forms consisting of a strip of sheetmetal intended for :placement on edge in vertical kerfs;

strip and adapted to engage the inside wall of,

a form with the free ends of the lugs.
