ROBERT REID, OIE SANFORD, MAINE.

nonnina-sarna?.

To all "whom it concern Be it `known that I, Ronn'r REID, citizen of the United States, residing at Sanford, in the county of York and State of Maine, have invented certain new and use ful improvements in Bonding-Straps; and l Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine. l

This invention relates to improvements in bondings forbuilding construction, and an object of the invention is to provide a bond `formed 'of `a one-piece strap for securing interior walls to an outer wall made of brick, concrete block, granite or other form oi' masonry, such 'bonding strap being proi vided with a roughenedtong'ue adapted to lie in themortar between the `courses of` masonry. u

A fiirther object of the invention is to provide a bonding strap which may be used for supporting interior walls in case a heavy `exterior wall is used, or in supporting `a thin outer shell of masonry from a wooden structure built according to the usual methods. y

With these and otherobjects in view the invention comprises certain novel construccombinations, andy arrangements of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings, where similar reference characters designate corresponding parts and wherein two uses of the invention areshewn, Figure 1 is a vertical section taken through part of a wall showing the invention as applied to a stone wall; Fig. 2 is an enlarged section taken through the tongue ofthe strap parallel to the wall shown in Fig.` l; and Fig. 3 is a perspective View of one of the ears upstanding from the tongue; Fig. 4r is a section taken through a wall of a wooden structure showing a shell of brick applied thereto; Fig.` iis a perspective detail of this improved bonding strap in the position it occupies when in use.

In the construction of stone buildings wherein walls are made of granite, brick or concrete block, it is desirable that some elticient but inexpensive method be provided .for securing the inner wall of the room to the stone wall of the building, and the bonding strap disclosed herein is designed Specification of LettersPatent.` Patcnted NOV, 24:, 1914;,` pplicatn filed June 16, 1913. Serial No. 774,079.` i Y primarily for, such purposes. However,`

the strap may also be used for the purpose of securing an outer shell of masonry to a `wooden structure so as to provide a double wall and also ail'ord an air space between the wooden structure and theimasonry to atlord a warmer toustruction.

Referring to the drawings, `particularlyy to Figs; l. and 2, it will be seen that the outer wallto which the interior wall is fastened, is formed of large blocks 10 ofany ""9- approved material, these blocks beingspaced by the ordinary bonding mortar l1. In ori der that the interior wall oil the room may be secured to the stone wall, studdings 112 are secured as by means of 'a bonding strap 13 which forms the subject-matter of the present invention, to` the Wall formed of` the blocks 10. These bonding straps 13 each have a vertical plate 111, the sides of which are bent back substantially at'right angles into longitudinal flanges 15 which are provided "with a plurality of openings 16 through which are to be driven nails serving as means for securing the bonding strap to thel studdiugs 112. oi several cxpcdients which may be resorted to for fastening the strap to the studdings 12, and I `do not wish to be limited to this particular construction. From the up er This is merelyone end of the body plate 1&1, and extending substantially at right angles therefrom is a perforated plate or tongue 17 which may be oi a width corresponding to the studdng and of a length to extend into the mortar 11 i'ar enough to be` bound securely thereby. ln thelorm shown ih Figs. 1 and 2, the

`tongue 17 is substantially JIplane and is provided "witlra plurality o peiforations `18 Vformed by striking from the tongue 17 a number of ears 19. The ears 19 are formed by first cutting them with substantially semic1 rcular dies and then bending them substantially perpendicular to the plate 1? When it is desired to use the bonding` strap shown herein, the tongue is laid in mortar or cement on one of the blocks 10, and the upper course is then laid uponthe mortar and over the tongue 17 so as to hold said bonding strap in position. Then the studding 1Q is secured to the bonding strap by nails or other devices passing through the openings indicated at 16, after which a wall 1 is secured to the studding 12, this wall in the drawing being shown as the ordin-ary lath and plaster wall, althoughit is i,

metal, etc. As many of the bonding straps` may be used as will be found necessary to hold the wall 1 in place.

When it is desired to use the bonding strap shown herein for the purpose of supporting the brick work to a wooden structure, thestrap 13 may be secured to a wall 1y by means of'studding 2', such bonding 'strap being placed so as to lie betweenthe adjacent courses of brick. If desired, the `wall may be started, after which the bonding strap 13 will be put in place with the `tongue 17 lying on top of the uppermost course after which a thin layer of mortar may be placedupon the top of the bricks belowv the tongue 17 and the bond plate 13 is 'A put in place so as to adord a bond from the lower bricks to the upper bricks through the perforations 18. Several courses may then be laid after which another of the bonding straps lvmay be put in place, all `of said straps vbeing secured to the studding 2. Obviously, no dificulty will be experienced in making the tongue 17 come practically even with the top of the course of' bricks insomuch as it is possible to slide the body plate 14- o the strap in place after a part of the wall hasbeen completed then secure the same to the studding. Insoinuch as the' outer shell is usually the thickness of one brick, the wall may be built very quickly but under usual construction, it is not desirable to build a brick wall of greater height than twelve or fourteen feet, insomuch as the weight of the upper courses upon the green mortar7 of the lower courses will s ueeze mortar out of the wall. .The tongues 1 serve to support the Weight of the` brick wall at intervals as well as to prevent bulging of the same with respect to ythe wooden structure 1.

vgimi.

The tops of the thin ears 9 may support the neXt course of bricks above each of the tongue plates 17 and still afford the usual Copies or this patent may be obtained for five cents each, by addressing the Commissioner .of Washington, D. G.

space for bondingY withy 'the' mortar. The straps may be made from sheet metal of sufficient strength to help support the brick wall and at the same time be resilient enough to admit of a slight movement between the brick shell and the wooden structure which would ensue upon swaying of the building under wind pressure.

It is quite possible to apply this device to a Wall already built, by driving the tongue 17 into the green mortar until the base plate rests flat against the brick and'then setting the studding against said plate and between the flanges in the spacethus adorded. In so driving in the tongue the ears 19 may become inclined somewhat, but that will have no disadvantageous effect.

` What l claim is l. The herein described bonding strap comprising an upright body` plate having right angular flanges along its upright edges spaced to receive the studding, said fianges being perforated for fastening devices, the entire plate being U-shaped in cross section, and an integral horizontal tongue projecting at right angles from the upper end of said body plate away from the fianges and roughened, for the purpose set forth.

2. The herein described bonding strap comprising an upright body plate having upright perforated flanges along its side edges spaced to receive the studding whereby the plate is U-shaped in cross section, and an integral horizontal tongue projecting from one end of said body plate and in a direction opposite from said flanges and adapted to pass between courses in a wall, said tongue having ears struck from it and bent upward on lines transverse to the tongue, for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses. i
