enii'iliyed for anchoring nailing strips therein.

In certain forms of fii'reproof construction it has been found desirable to 'employ so-c`alled metal lui'iiber consisting of pressed steel structural shapes such as I-bea'ms formed by welding 'two pressed steel chanthe sleepers or nels back to back. AInthis form ofconstruction it is common to employ a lmetal 'lath and to inold thereon a section of concrete on which a wood floor may be laid. It isY necessary therefor that a nailing strip be mounted in the concrete above the structural member. In order to effect this result several different expedients have been adopted all of which are open to objections.

In the construction here disclosed I provide means for rigidly securing the sleeper in position and utilize a well known means l'S0 employed for securing the metal lath to the structural shape.

The invention will be more readily understood by reference to the accompanying drawings, wherein,

Fig'. l is a fragmentary plan view showing an application of my improvement;

Fig. 2 is a sectional view somewhat enlarged on the line 2-2 of Fig. l; Y

Fig. 3 is a plan view of the device in its manufactured form;

Fig. l is a side elevation thereof;

Fifi'. 5 is a sectional view on the line 5 of Fig. 3;

Fig. Gis a sectional view illustrating a slightly modified forni of the invention;

Fig. 7 is a view taken at right angles to that of Fig. G, and,

Fig. 8 is a plan view of the same construction.

In the drawings it will be seen that the improvement is specifically applied to a structural shape consisting of pressed steel channels 10, placed back to back and united by welding thereby forming an I-beain.

.rtriicti'on and particularly to novel 4means land tliisis secured in' place by employing a -sl'nifingwvire i clip consisting` of legs l12, having hook ends 13, and an intermediate -body or connecting member 14, which is curved lfrom 'end'to end, as best shown in F tl. In practice this is applied by proje;tiiig one end through a"n"opening in the metal '-lath and engaging the hooked end with a flange 15, of the structural'member'. The opposite end is then for-ced through an opening against the tension of .the metal until the hooked lend engages around a correspondingjflange `on the opposite sider ofV the 'I-beani. VTo this fastening clip I apply my sleeper anchor, which consists lof a fiat strip of metal 16,- having tongues 17 struck out therefrom which are adapted to engage over the middle portion of the body 14 of the clip. Located at a proper point 'between the ears 17 and the fr'eeeii'ds of the Y strip are 4slits 118 'of' a length ysomewhat greater than the distancebetween thevears and the angles of the fastening clip. Thus the strip may be formed in the position shown in F ig. 4; and the strip may remain inV this uneXposed position until the sleeper isy laid4 At that time the free ends of the strip are bent upwardly and may overlap,

as shown in'Fig. 2, a nail 19 passing through the metal of the strip and entering the nailing strip. Thereafter concrete, indicated at 20, may be molded in place.

In the construction shown in Figs. 6 to 8 inclusive, the parts aie composed of a single length of wire, the terminal portions of which are provided with hooks 21, which engage beneath the flanges of the structural member. At a point midway of the ends of the body 22' of the wire I construct loops 23,'perpendicular to the plane of the floor a-ndpspaced apart a distance equal to the width of the nailing strip to be employed. A portion of wire 24 extends between the adjacent loops, said portion, as shown in Fig. 8, projecting diagonally in lorder that device being composed of a single length of wire may be cheaply constructed and for this reason presents some advantages.

On the top of the beam is laid metal latli In each "of the constructions described the l10 sfiql sleeper is firmly held in position directly above the structural member and utilizes the clip which is employed for securing the metal lath in position. Other modcations than that illustrated may be* made without departure from the spirit of my invention and I do not Wish to be limited except as indicated in the appended claims.

One of the particular advantages inv the slotting of the .strip is that a standard strip may be utilized for different sizes or lengths oi clips. It will be understood that the structural members vary in Width according to diilerent requirements and the fastening clips must be correspondingly varied in length. By forming the slits of adequate length in the rst instance, the same straps may be attached to and employed with clips of different lengths. One of the particular objects in slitting the strips is to enable the strip to be secured underneath the clip. Thus the Jfastening tongues which are employed for unitking the strip and the clip have only the function of uniting the parts during the handling` and installation.

I claim: y

l. Means for anchoring a nailing strip to metal structural members comprising in combination7 a clip adapted to span the structural memberin hooked engagement with the flanges thereof, and a strap engaging the middle portion of the clip and having its free ends slotted to pass orer the angles of the clip.

2. An anchoring device for nailinw strips comprising a spring-metal clip adapted to engage a structural member, and a strap secured tothe clip and slotted to permit of bending of the ends of the clip through the plane of the strip.

3. In a sleeper anchor the combination of a clip of U-shape and a strap arranged parallel to the base of the U, the central portion of the strap being located Within the U or' the clip, the ends of the strap being slotted to permit said ends to be bent to extend oppositely to the legs of the U-shaped clip.

4. Means for simultaneously securing metal lath to structural members and nailing strips upon said latli, comprising a spring-metal `U-shaped clip, the legs of which are adapted to pass through the lath and engage the flanges ofa structural member, and portions projecting from the mid dle of the base or' said clip and adapted to embrace a nailing strip.
