UNITED STATES HENRY C. MGCLUEE, OF LOS ANGELES, CALIFQEll'Lh.
WALL TIE AND FORM HOLDER.
I Application filed July 21,
To a-ZZ w ham may concern Be it known that I, l-innny C. MOCLURE,
a citizen of the United States, residing at,
Los Angeles in the county of Los Angeles and State of Californiahave invented newand useful Improvements in Wall Tie and Form Holders, of which the following is a specification.
This invention relates generally to building constiructiom-and more particularly to a combined wall tie and form holder that is designed for use in the production of hollow walls of concrete or like hardened plas- The principal objects of my invention are to provide a relatively simple tie and form holding device that may be easily and cheaply producedandwhich will be very effective in performing its intended functions.
lVith the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts that will be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:
Figure 1 is a perspective view showing devices of my improved construction supporting a series of forms upon the ground and in position to produce a hollow wall.
Fig. 2 is a perspective view showing devices 01 my improved construction supporting forms in position to produce the second course of a hollow wall structure.
Fig. 3 is a perspective view showing a portion of a hollow wall structure and with the parts of said wall tied to each other by the devices contemplated by my invention.
Fig. 4 is an enlarged cross section taken approximately on the line 4- i of Fig. 2.
Fig. 5 is a perspective view of the combined tie and form supporting device contemplated by my invention.
The combined tie and form support is preferably formed of wire or narrow strips of metal, and each member comprises a substantially straight intermediate portion 10, straight end portions 11, and horizontally disposed loops 12 between said intermediate and end portions. The extremities of the straight end portions 11, are bent upwardly to form vertically disposed fingers 13, and secured in any suitable manner to the end portions 11 between said fingers 13 and the loops 12 are'vertically disposed fingers 14, and which arrangement provides spaces 15 between the respective pairs of fingers 13 1921.

and 14k, and which spaces are adapted to receive the lower portions of the panels 16 that form the outer walls of the building forms.
secured to'the'intermediate portion 11) of each tie and holder are pairs of upwardly projecting fingers 17 that are adapted to receive and retain in proper position the inner panels 18 of the building forms.
Inthe use of my improved ties and term holders for the construction of a hollow wall, a number of ties are arranged on the ground or the foundation for the hollow wall with the fingers 13, 1 1 and 17 upwardly presented. The intermediate panels 18 are now positioned between the pairs of fingers 17 after which the outer panels 16 are positioned between the pairs of pins 13 and 1A. The horizontally disposed loops 12 resting upon the surface of the ground or 'foundation maintainthe devices in position so that the fingers 13, 14 and 17 project upwardly, and thus the panels of the forms are maintained in upright positions and spaced the proper distances apart. To firmly retain the panels in such positions, a number of the combined ties and holders may be arranged on the upper edges of said panels with the fingers of said devices projecting downwardly. The plastic material from which the wall is to be formed is now poured into the spaces between the outer and inner panels thereby providing parallel wall portions that are spaced apart, and after this first filling or course of plastic material has become set and hardened, the panels are removed and repositioned on top of the first course and retained in such positions by arranging tie members on top of the first course of concrete and by tie members that are applied to the upper edges of said panels (see Fig. 2). Obviously this method of construction of a double wall leaves the end portions of the tie members, or those portions provided with the fingers 13, projecting outwardly from the outer faces of the parts of the wall, and after the wall has beencompleted, these projecting portions may be sheared or cut off in any suitable manner. Thus the parts of the complete double wall are effectively tied to each other by the embedded tie members and a firm and substantial structure is produced. 1
The use of a device of my improved construction in the building of wall structures and the like minimizes the amount of lumher required for forms or panels that retain the plastic material while the same is becomin set and hardened, for it will be observed that a single set oi. four panels and a sufficient number of the combined ties and holders are all that are required in the con- 'struction of a double wall.
While I have shown and described the combined tie and form holder as being constructed of wire, it will be understood that the device may be formed of relatively narrow strips of sheet metals, or that practically the same structure may be cut or stamped from sheet metal with suitable dies.
A combined wall tie and form holder of my improved construction is relatively simple, may be easily and cheaply produced, and by its use much of the material, as well as the time and labor involved in the building of hollow wall structures is eliminated.
It will be understood that minor changes in size, form and construction of the various parts oi? my ii'nproved building construction may be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims.
I claim as my invention.
1. A combined wall tie and building form holder having a substantially straight body portion, fingers projecting at right angles from the ends of said body portion, and closed loops projecting laterally from said body portion between said fingers.
2. A combined wall tie and building form holder having a substantially straight body portion, pairs of fingers projecting at right angles from the ends of said body portion, loops projecting laterally from said body portion between said pairs of fingers, and
4. A device of the character described comprising a single length of wire bent between its ends to provide loops and at its ends to form right angularly disposed fingers, said loops being disposed in the same plane and the fingers being disposed in the same plane but at a plane at right angles to the plane of the loops.
5. A device of the character described comprising a substantially straight body portion, fingers projecting at right angles to the ends of said body portion, loops projecting laterally in said body portion between said fingers, and other fingersprojecting at right angles to the body portion between said loops.
6. A device of the character described comprising a single length of wire bent between its ends to provide loops and at its ends to form angularly disposed fingers, and short pieces of wire secured to the first wire and arranged to formfingers.
7. A device of the character described comprising a single length of wire bent between its ends to provide closed loops and at its ends to form right angularly disposed fingers, said loops extending from one side of the wire and disposed in the same plane, and the fingers being disposed in the same plane but in a plane at right angles to the plane of the loops.
In testimony whereof I have signed my name to this specification.
