hearse stars till.


Application filed January My imention relates to a device "for leveling; and anchoring wooden iloor sleepers, shownin the accompanying drawings and more particularly described in the follow ing SIMBCl'ilCELtlOD and claim.

in laying wooden flooring upon a concrete base it is essential that the floor slee i should be properly leveled and anchored to the concrete base, that the flooring nailed thereto may be rigid and on a horizontal plane.

ltleretolore it has been customary to insert shims or wedges beneath the sleepers that they may lirst 'be properly leveled up on the concrete slab hetero the concrete tilling is poured between the sleepers to the level ot thetop of the latter. It has also been customary to previously insert a plu rality o't metal strips in the concrete bed while the latter is in a plastic condition, the strips being inserted so that they will project above the concrete for attachi'ncnt to the floor sleepers.

Both of these devices however have been found objectionable as it requires considerable time and labor to properly line up the sleepers to an even plane by driving wedges under the latter b fore pouring the concrete filling between them and the time thus spent represents a large proportion of the cost of building a floor of this character. So also the metal strips employed to anchor the sleepers to the concrete bed must be inserted while the latter is in a plastic state with their ends projecting sufticiently that they may be nailed to the sleepers. To do this it becomes necessary "for the workman to wall: over the concrete bed While in a plastic condition to insert the strips therein, which frequently results in disturbing the concrete, and he must also go over the surface again to nail the projecting ends of the strips to the sleepers laid upon the slabs.

The purpose of the present invention thciet'ore is to provide a device which is adapted not only to level the sleepers upon the concrete slab but which serves to anchor them thereto the construction being such that the sleepers may be quickly and easily leveled upon the concrete bed after the latter has hardened,a concrete filling being subsequently poured between the sleepers, anchoring the latter rigidly to the slab.

A further object of the invention is to provide a device which is inexpensive to construct and which may be easily and 21, 1925. Serial no. 3,851.

quickly secured to the sleepers and readily adjusted to bring the latter to an even plane. To this end the device has been formed of sheet metal, slit at each end to partially divide it longitudinally,-one-halt oi each slitted end being bent upwardly to form li-shaped member adapted to receive the sleeper and to which its tip-turned ends are nailed,the horizontal ends of the strip being tapped to receive a pair of screws which when adjusted are adapted to raise or lower the sleeper as may be required to bring it to a horizontal plane with others simultaneously provided with a pliiirality of devices or like character,

in the drawings accon'ipanying this specification: c

Figure l is a side elevation of the device supporting a sleeper shown in cross-sectionupon a rough floor level or base.

Figure 2 is a vertical cross-sectional view through a floor sleepershowing the concrete slab forming the rough floor level and also the concrete filling poured between the sleepers. 1

Figure 3 is a perspective view of the deyice showing a fragment of a floor sleeper 1n dotted lines.

Figure t is a perspective view of a modification 01 the device shown in Figure 3.

Referring now to the letters of reference placed upon the drawings 1 A denotes a rough floor level or slab of concrete.

B indicates a wooden floor sleeper and C an adjustable supporting shoe and anchor plate formed of sheet metal-the ends of which have a central longitudinal slit, whereby one-half of each end may be bent upwardly to form with the connecting horizontal portion a U-shaped or channel member. lhe upstanding walls G of the channel portion overlap the side walls of the sleeper and are secured to the latter by nails D, driven therein "from opposite sides of the device,

The horizontal enns C of the device tapped to receive a pair of screws or bolts E which upon adjustment serve to raise or lower the sleeper upon the rough concrete bed as may be required. When the sleepers are all properly leveled upon the concrete bed by the adjustment of the screws regulating their altitude, a concrete filling A is poured upon the slab between the sleepers up to a line approximating the upper surface of the latter. The concrete filling when hard becomes an integral part of the rough concrete base and having embedded the several leveling devices therein see Figure 2anchors the sleepers to the concrete base.

F denotes a wooden flooring nailed to the sleepers in the usual way.

In Figure l is shown a modification of the device in which the ends forming the side walls of the U-shaped chaiinel'are staggered. Thus the nails which'secure the upturned ends tothe sleeper are spaced apart while remaining on a horizontal plane to each other.

In the construction shown in Figure 3 the hails attaching the deviceto the sides of the sleeper will have to project through its walls on difi'ere'nt planes 'inorder that they may not interfere when driven into the sleeper from opposite sides of the device.

While this device has been described as made fromfa sheet metal plate slitted longitudinally at each end, with one of each of the slitted ends bent upwardly to form a channel for the sleeper, the remaining horizontal end portions or fins being tapped and fitted with screwsffor "regulating the altitude of the devi'ce,it will be obvious that it may be made'of cast-metal with horizontal fins integral with the channel portion and tapped for the passage of screws adapted when adjusted to regulate its altitude. Having thus described my invention what I claim is:

A device of the character described comprising a fiat sheet metal plate longitudinally'slitted from each end to divide said plate medially for a portion of its length, with one portion of each slitted end of the plate bent at right angles to the remaining adjacent slitted portions of the plate,whereby two upstanding opposing walls are provided spaced apart to receive and overlap the sides of a wooden strip,' said upstanding walls being punched for the passage of nailswhereby the wooden strip may be secured theretothe horizontal slitted end portions being on the same plane with the major portion of the plate and tapped to receive adjusting screws; and a' pair of adjusting screws respectively screwed through each of said horizontal'slit'ted end portions of the plate, whereby the device may be adjusted to regulate the altitude of the wooden strip carried thereby.

In testimony whereof, I sign this specification.
