WALL-TIE Specification of Letters Patent.

Patented Aug. 3, 1909.

Application filed November 4, 1903. Serial No. 461,060.

. To all whom it may concern:

Be it known that I, JAooB H. COFFMAN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful 1m rovements in Wall- Ties; and I do hereby eclare the followin to be a full, clear, and exact description 0 the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

M invention relates to wall ties designed for inding the pressed brick facing of a brick wall to the courses of the common brick composing the inner or main wall.

It has for its object to provide a wall tie of simple construction which is also cheap of manufacture and is thoroughly ractical and eflicient for the purpose for w ich it is designed.

Other objects will become apparent from the following description.

The invention consists broadly in dprovidin the wall tie with a lug arrange about midway thereof and adapted to fit between the courses of brick forming the inner wall and those forming the outer wall or pressed brick facing. Said lug is preferably turned upward so that it will not interfere with building against it. The wall tie is also provided with a lug at one end adapted to fit down over the inner edge of the inner wall.

The invention consists further in the features of construction and combinations of parts hereinafter described and specified in the claims.

-In the accompanying drawing, illustrating the preferred embodiment of m invention: Figure 1 is a plan view showing ow my wall tie is applied in use. Fig. 2 is a perspective View 0 t e wall tie alone, and Fig. 3 is a similar view of a modified construction.

In carrying out my invention, I construct the wall tie from a strip of metal, preferably wire. The stri or wire is bent to form op positel exten ing prongs arranged along side 0 the shank 1. One pron 2 extends about one half the length of the s ank and is provided with a lug 3 which extends u wardly and is adapted to fit between t e courses of brick composing the inner wall and those making up the outer wall or pressed brick facing. It is preferable 'to ave this lug project u wardly rather than downwardly because it as been found that it will not then interfere or cause any delay in buildin. against it whereas if it extended downward y it might result in more or less hindrance and delay because of it having to be inserted in the joint especially if tightl built. The other prong 4 extends the ful length of the shank and carries a downwardly extending lug 5 ada ted to fit over the inner edge of the inner we 1. This is shown in Fig. 1 of the drawin in which "A indicates a art of one of tie bricks of the inner wall and B a part of one of the pressed bricks forming the outer wall or facing. As shown in Figs. 1 and 2 the prongs are preferably bent into wave-form to give them a better hold u on the mortar in which they are embedded Said prongs may, however be made straight as illustrated in the modified form in Fig. 3. It will be noted that the use of the rong adds reatly to the strength of my wal tie, there ein two strands of the wire across the two wa s and three strands across the inner wall.

I claim:

1. A wall tie made of a strip of metal bent to form a cgntral; shank having oppositely arranged prongs projectin from elt er end and extending along the s ank, one of said pron s extending the full length of the shank and having a lug at its end to fit over the edge of the inner face of the wall.

2. A wall tie made of a strip of metal bent to form a central shank having op ositely arranged prongs projectin from elther end and extendin alon the s ank one of said prongs exten ing a out one half the length of said shank and havin a lug at its end to fit between the courses 0% common brick and those of pressed brick composin the wall.

3. A wall tie made of a strip 0 metal bent to form a central shank having op ositely arranged prongs projecting1 from at er end and extendin alo the s ank, one of said pron s exten ing a out one half the length of sald shank and having a lu ward at its end to fit between tie courses of common brick and those of pressed brick composing the wall.

4. A wall tie made of a strip of metal bent to form a central shank having oppositely arranged prongs projectin from elt or end alon the siank one of said prongs exten ing a out one half the len th of sand shank and havin a lug at its on to fit between the courses 0% common brick and those of pressed brick composing the wall, said prongs being bent into wave-form suband extendin turned up-.

stantially specified.

5. A wall tie made of a strip of metal bent to form a central shank having oppositely arranged prongs projectin from either end and extendin along the shank, one of said pron s exten ing the full length of the'sl'iank and aving a lug at its end to fit over the edge of the inner face of the wall, the other prong extending about one half the length of said shank and having a lug at its end to fit between the courses of common brick and those of pressed brick composing the Wall.

6. A wall tie made of a strip of metal bent to form a central shank having oppositely arranged prongs projecting from eit er end as shown and for the purpose and ext'endin along the shank, one of said prongs extending the full length of the shank andhaving a lug at its end to fit over the edge of the inner face of the Wall, the other 20 prong extending about one half the length of said shank and having a In turned upward at its end to fit between tie courses of common brick and those of pressed brick composing the wall. 25 In testimony whereof, I aflix my signature, in presence of two Witnesses.
