Nov. 11, 1930. J. E. MACKIE ET'AL FLOOR SLEEPER Filed March 3, 1930 N Am m mm m B Y Y zrjomvs v Patented Nov. 11, 1930 UNITED STATES PATENT oFFI'CE JAMES E. MAGKIE AND AARON 3'. SMITH, LONG- BEACH, CALIFORNIA- FLOOR SLEEPER Application filed March 3,

This invention relates to a floor sleeper, screed and furring strip which is adapted to be positioned in a concrete floor or in a wall. When in position, the sleeper afiords'a means for securing flooring and the like over a concrete base, or to secure wall covering or trimming when used as a furring strip.

An object of our invention is 'to provide a sleeper of the character stated which can 10 be quickly and easily placed in position in the floor or wall, and when placed in the floor will materially reduce the overall height of a building. Another ob'ect is to provide a sleeper which can also be eflectively used as a screed for the concrete or cement floor.

An advantage of our sleeper is that it may be installed in multiples, thus materially decreasing the time necessary to install the sleepers.

Another advantage of our sleeper is that it is securely anchored in the concrete.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description, and the appended claims.

In the drawing Figure 1 is a transverse sectional view of a pair of sleepers in operative position, and

with the flooring secured thereto.

Figure 2 is a transverse sectional View of a slightly modified form of sleeper.

Figure 3 is a side elevation of one of the sleepers. I V

Figure 4 is a plan View of a plurality of sleepers secured to master strips prior to installing.

Referring more particularly to the'drawing, the numeral 1 indicates a metal case, 40 preferably formed of acomparatively light sheet metal which can be readily stamped into the shape desired. The case is formed into a substantially rectangular trough 2 in which a wooden strip 3 is placed. The strip 3 is preferably creosoted so as to materially lengthen its effective life. At the upper end, the case 1 is bent outwardly into flanges 47-4 and these flanges are bent downwardly at their outer ends to form spacing ribs 5. As 50 shown in Figures 1 and 2, the concrete floor 1930. Serial 116.432,?32;

comes to the level ofthelower 'edge of the spacing ribs 5, and theseribs thus provide a screed to lev'elfloff the concrete floor, as will be described in detail later. To securely anchor the case 1 intothe concrete floor or wall 6, we provide at the lower edge of the case longitudinally extending anchor ribs 7 The anchor ribs ar'e integrally formed with the metal case, and as w'ill be evident, provide an efle'ctiv'e' means against removal or displacementof the sleeper. The flooring or the like 8 is placed over the sle'epers and nails 9 are .driven'through the floor. ing into thewooden strip 3 and the nails as they come in contact with the bottor'n of the case 1, will be clinched over as shown in Figuresland2. j,

To hold the wooden strip 3 securely in the case" 1,"we provide a plurality of cars 10 which are cut out ofthje sidesiofth'efcase, and are drivenijnwardly into the wooden, strip, thus securely holding it against 1displace ment. ,7 M p p Our sleepers may be positioned in'the following'mannerr A plurality of the, sleepers are secured to master strips ll llb'y means of nails which extend'through the flanges l. The master strips and theattachedjsleepers are leveled by any suitable and 'well-kfnown means, after which the concrete flooring is poured, The ribs: 51act'as a screed togage the top surface ofthe floor.

A slightly'modified form of sleeper is 7 shown in Figure 2. The metal case 12 is stamped into'the shape of a truncated'prism in cross section, I and the wooden strip 13 conforms in shape to the metal case; By this means the wooden strip is securely held in position without requiring the cutout ears as previously described. Outwardly extending flanges 14 -14 areprovided at the upper end of the case, and these flanges are turned downwardly into spacing ribs 15 which are identical in construction to the flanges 4 and ribs 5.

Having described our invention, we claim:

1. A sleeper or strip comprising an elongated metal case, said case being formed in the nature of a trough, a wooden strip secured in the caseand depending ribs at, the upper end of said ease.

2. A sleeper and strip comprising a metal case formed into an elongated trough, a wooden strip positioned in the trough, outwardly extending flanges at the upper end of thecase, said flanges being bent downwardlyinto depending ribs, 3'.
