ANCHOR FOR SLEEPEBfi.

1 Application filed February In modern building construction, the lay ing of wood floors on concrete is attended with diiliculties resulting in excessive cost and often in defective construction. In some instances, sleepers are temporarily held in place on a hardened concrete base by means of bracesrcaching upward to the ceiling, an additional layer of concrete being poured between'the sleepers to anchor them to the base. In other instances, sleeper securing devices are sunk into and embedded in the green concrete base, the sleepers being fastened to said securing devices after the concrete has set. .ln-the first method the cost of extra material and labor is high. In the second method, a number of difliculties arise. If the concrete is too soft, itis distorted by the necessary foot boards upon which the laborers walk, thus resulting in extra labor in the leveling of the wood floor, which at best is unwo-rlnnanlike. If the concrete is too hard, it is impossible to apply the securing devices. The relatively short time most practical for the application of said devices is limited, and, often coming out of working hours, occasionsconsiderable inconvenience and added expense in obtaining the requisite labor.

Theobject of my invention is to provide a simple, inexpensive and efficient anchor for sleepers which may be readily applied to a concrete floor, after it has set sufficiently to withstand the weight of laborers walking thereon, and, during the relatively long period before the concrete becomes substantially hardened.

\Vith the foregoing and other objects in view, which will appear in the following description, the invention resides in the novel combination and arrangement of parts and in the details of construction hereinafter dc scribed and claimed.

in the drawings, Fig. 1 is a perspective view of a device embodying my invention; Fig. 2 is a similar view, showing the flanges folded in overlapping relation upon the floor plate; Fig. 3 is a perspective view illustrating the manner in which the device is used and Fig. 4 is a perspective view of an alter nate form of my improvement.

Reference being had to the drawings,- it will be observed that my improvement is formed from a strip of sheet metal. This strip is scored transversely as at 10 at either side of the center thereof, the medial section defined by said scores comprising a base A 1 1923. Serial No. 619,019.

and the terminal sections comprising attachins flanges 11. In the form illustrated in Figs. 1, 2 and 8, the medial section is turned upon itself near the ends thereof, those por- $10115 12 of the strip overlapping the end margins of the floor plate 13 of the base A serving to station 'the roots of the flanges 11 inwardly ofthe ends of the base and thereby form reinforced ears I). Said reinforcing, flange insetting portions 12 have apertures 12 therein registering withapertures 13 in the floor plate 13. These registering apertures 12 and 18 receive anchoring nails 14; and are located so as to bring the heads 11 of said nails closely adjacent to the scores 10 at the rootsof the flanges 11. Said flanges '11 are adapted to be turned into upright po sitions to receive a sleeper 15 3.), aper- 'tures 11 being formedin said flan es to receive securing nails 16 driveninto the sides of the sleeper.

The reinforcing, flange insetting portions 12, as shown in Figs. 1 and 2,. are not pres "ent' in the alternate form illustrated in Fig. i. The flanges 11 turn upward from the extremities of the floor plate 13 on the scores 10. Apertures a near the ends ofsaid plate receive nails 14, said apertures being arranged to bring the heads '14 ofcsaid nails in close proximity-to the scores 10, whereby said heads insure the turningof the flanges 11 on the root lines thereof, without the distortion of parts.

In use, my devices are secured to partially set concrete slab, as at 9, by driving thenails 1 1" into the concrete and through the registering apertures 12 ant 13 in the ears Z). On account of the usual traffic. over a concrete floor between the time of application of the anchoring devices and the time of laying the wood floor, the flanges 11 are preferably left in flattened relation (Fig. 2) until the sleepers are to be 'd. At such time, said flanges 11. are readily turned upward, the bending thereof being easily accomplished without distortion of the parts by reason of the scores 10 and the near pro):- imity of the nail heads 14? to said scores. Sleepers 15, embraced between the flanges 11 of aligned anchoring devices are secured thereto by means of nails 16 driven through the apertures 11 in said flanges. With the sleepers thus firmly anchored to the concrete floor, floor boards 16 are applied in the usual manner.

Changes in the specific form of my inllO vcntion, as herein disclose, may be made within the scope of What is claim d withoutdeparting from the spirit of my invention.

Having described my invention, What I claim as new and desire to protect by Letters Patent is:

1. A device of the Clih'?) described formed from a strip of sheet metal, the me lial section thereof comprising a floor plate, the transverse sections adjacent medial section comprising combined spacing and reinforcing members, the same bcinoturned in- Wardly upon the margins of said plate, and the terminal sections of said strip comprising attaching flanges, said flanges being scored at their roots to permit of the ready bending thereof from overlapping relation on the floor plate into upright sleeper embracing positions, said medial and adjacent sections being formed with apertures registering to receive anchoring elements and said terminal sections being apertured to receive sleeper securing means.

2. A device of the class described formed from a strip of sheet metal, the medial section thereof comprising a lloor plate, the transverse sections adjacent said medial section comprising combined spacing and reinforcing members, the same being turned inwardly upon the margins of said plate, and the terminal s ctions of said strip comprising holding flanges, said flanges being adapted to be bent from overlapping relation on the floor plate into upright sleeper embracing positions, said medial and adjacent sections being formed with registering apertures and nails adapted to be driven into a base and through the registering apertures for anchoring the device, said apertures being arranged to bring the heads of the nails in close proximity to the root lines of the flanges, whereby the bending of said flanges on said lines is readily accomplished Without distortion of parts.

3. A device of the class described formed from a strip of sheet metal scored transversely at either side of the center thereof, the section between the scores comprising a floor plate and the terminal sections coinprising attaching flanges said floor plate being apertured at either end thereof near the scores to receive anchoring elements, said flanges being adapted to be bent upon the scores from overlapping relation upon the floor plate into uprigh" positions to receiv a sleeper.

4. In a device of the class describe l, a floor plate, opposed flanges on said plate adapted to be folded in overlzmping relation upon the plate to form com {ct st and also adapted to be bent upward fi'oizi said plate to term spaced sleeper en'ilfnraci elements, the base portions of said all being permanently lapped upon the p and together with said plate forming reinforc-cd anchoring elements, and means co-operation with said elements and with a floor to anchor the device to the floor,

A. device of the class described, comprising a sheet metal strip, the ends of the strio being bent inward upon itself, thence upward therefrom, the medial section of the strip comprising a floor plate, the ends of said plate, together with the inturned tions of the strip comprising reinforced ears of lapping material, said upwardly extending portions comprising attaching ilan and means cooperating with said cars loianchoring the device to the floor.

6. in a device for anchoring a sleeper to a floor, a strip of sheet metal scored transversely at either side of the center thereof, the section between the scores comprising a floor plate and the terminal sections comprising attaching flanges, said floor plate being apertured at either end thereof near the scores to receive nails adapted to be driven therethrough and into the floor, said apertures being thus arranged to bring the heads of the nails in. close proximity to said scores, whereby they are caused to clamp the floor plate to the floor at points near said sco-es and thereby minimize distortion of parts during the bending of said flanges at the scores.

In testimony whereof, I have Elli-J name to this specification.
