United States Patent JOEST PUCKETS Frank Patrick McElwee, Baltimore, Md.

Application April 11, 1955, Serial No. 500,468

2 Claims. (Cl. 2095) This invention relates to metal brackets or pockets used to support wooden structural members, and more particularly to support the ends of beams or joists where they join walls of columns.

The general object of the invention is to provide a device of this nature which shall be capable of effectively securing the ends of joists and the like to walls, especially brick walls and chimneys, without breaking into or damaging such Walls.

Another object is to devise a pocket or bracket of this kind so constructed as to provide a space through which nails may be driven into the joist at a point closely adjacent the wall so that the usual fascia boards or boxing may be applied around the beams or joists, if desired.

in order that the invention may be readily understood, refer nce is had to the accompanying drawings, forming part of this specification, and in which:

Fig. l is a side elevation of my improved joist pocket as it appears when applied to a brick wall, a fragment of the joist being also shown;

Fig. 2 is a vertical section substantially on the line 2?. of Fig. 1, looking in the direction of the arrows;

Fig. 3 is a horizontal section substantially on the line 3 3 of 1, looking in the direction of the arrows; a .d

Fig. 4 is a perspective view of my improved pocket itself.

Referring to the drawing in detail, A designates a brick wall of the usual construction; B, a beam or joist to be supported; and C, the fascia boards or boxing commonly employed.

My improved pocket or bracket comprises a rectangular metallic member or box having side walls 1 and 2, and top and bottom walls 3 and 4, respectively. Both ends of the box are open so that the beam or joist may be readily inserted therein.

Formed integral with the top and bottom Walls 3 and are tongues 5 and 6, respectively. The tongue 5 comrises a portion 5 lying in the plane of the top wall 3 and extending a definite distance to a point 5 at which point the tongue is bent at right angles and extends vertically upward.

Similarly, the tongue 6 has a portion 6 lying in the plane of the bottom wall 4 and extending a definite distance to a. point 6 at which point it is bent at right angles so as to extend vertically downward.

It will thus be seen that the faces of the tongues 5 and 6 lie in a common vertical plane, and that this plane is spaced or offset from the vertical plane defined by the edges 1 and .2 of the side walls 1 and 2.

The top and bottom walls 3 and 4 are provided with pairs of nail holes 3' and 4', respectively, and the tongues 5 and 6 are formed with pairs of bolt holes 5 and 6', respectively.

In applying the pocket to a brick wall such as shown in Fig. l, the tongues 5 and 6 are placed flat against the wall and are secured thereto by means of bolts 7. In the case of a brick wall these bolts may be in the nature of expansion bolts, and if applied to a wooden frame they may be in the nature of lag screws.

The beam B to be supported and which may be made up of a pair of 2" x 8" joists as shown, is inserted in the pocket or bracket and extends through the same into substantial contact with the wall. These joists may be secured to the pocket by means of nails 8 driven through the holes such as 3' or 4.

By virtue of the portions 5 and 6 of the tongues 5 and 6 it will be seen from an inspection of Fig. 1 that the rear edges l and 2 of the pocket are spaced a substantial distance from the wall, as indicated at 9. When, therefore, as usual, fascia boards or boxing C are used to enclose the beam or joists as shown in Figs. 2 and 3, these boards may be secured to the joists by driving nails it through the same and through the space 9 between the pocket and the wall. These boards, of course, overlie the pocket and enclose the same as shown.

From the foregoing it will be seen that I have provided an exceptionally simple and etrective device for anchoring the end of a beam or joist to a wall, particularly a brick wall or chimney, without damaging the wall, all that is necessary being to drill a few holes for the reception of the expansion bolts, and it is thought that the many advantages or" the invention will be readily appreciated by those familiar with such matters.

What I claim is:

l. A joist pocket for attaching the end of a joist to a vertical wall, said pocket comprising a rectangular ietal box having side walls, and top and bottom walls, but open at its opposite ends, supporting tongues projecting from the edges of said top and bottom walls and extending upwardly and downwardly respectively, said tongues lying in a common plane, which plane is parallel with but spaced a substantial distance from the plane of the rear end of said box, whereby a nailing space is provided between the rear edges of said box and the wall.

2. A joist pocket for attaching the end of a joist to a vertical wall, said pocket comprising a rectangular metal box having side walls, and top and bottom walls, but open at its opposite ends, supporting tongues projecting from the edges of said top and bottom walls and having the portions adjacent thereto lying in the planes of said walls up to a definite point, said tongues beyond such point being bent upwar ly and downwardly, respectively, and lying in a common plane, said plane extending parallel with but spaced a substantial distance from the plane of the rear end of said box, whereby said box is held by said tongues away from the wall to provide a nailing space between itself and the wall.
