ANCHOR FOR FLOR SLEEPERS.

application aies septeaibeig so. 1927.` serial No. 222,996.

The main objects ot' this invention are to provide an improved form of bar support; to provide an improved bar support and spacci' particularly adapted for use in concrete construct-ion Work; to provide impro-ved means for supporting floor sleepers; to pro vide improved means for anchoring the sup-` porting means in the concrete; to provide improvedspacing means; `to provide improved fastening means for securing the sleepers to the supports; and to provide a device of this hind which combines the supporting, anchoring, spacing and fastening means in a durable unitary structure. V

Illustrative embodiments of this invention are shown in the accompanying drawing, wherein Figure 1 is a vertical fragmentary section ot a concrete slab to which a sleeper is secured by an improved anchor, the dotted out lines representing the Jfastening means in their operative positions.

Fig. 2 is a perspective showing a sleeper secured to a slab by the improved anchor illustrated in Fig. 1.

Fig. 3 is a fragmentary perspective oi' one of the anchors shovvn in Figs. 1 and 2.

Fig. 4 is a View similar to Fig. 1, but showing a. modified form o1 anchoring device.

Fig. 5 is a. fragmentary perspective showing tivo floor `sleepers supported on the niodiiied form of anchor illustrated in 4.

Fig. 6 is 4a fragmentary perspective oi" the modified form of anchor shown in Figs. 4 and 5.

Fig. 7 is a perspective of another' modified form of anchoring device to which this invention is applied.

In the forms shown, the improved anchors Iare used for supporting loor sleepers or bars l on a concrete slab 2. Floor sleepers are usually disposed in substantially parallel spaced relation toform a Wooden frame structure to which the customary floor boards are nailed.

In the forms shown, the improved anchoring devices comprise a supporting member which is provided With anchoring portions adapted to be embedded in the concrete or other support, and seat portions which are adapted to support the-sleepers and which are folded to provide Jfastening means for attachment to the sleepers.

The improved anchoring devices may be made of any suitable material but are preferably formed ot Wire rods which may be readily bent to the desired shape.

ln the forni shown in Figs. 1, Q, and 3, the anchoring device comprises a. pair of supporting rods 3 arranged` in substantially parallel spaced relation. Each of the rods 3 is crimped at intervals to form a plurality of substantially V-shaped anchoring portions 4 which are arranged in pairs.

The portion of the rods 3 located between the anchors 4 of each pair oi anchors provides a seat olor engaging the sleepers 1,Which are disposed longitudinally et the rods 3. Each ot' the seats 5 is folded upon itselie to provide an arm 6, which may be bent at 'suby stantially right angles to the seat 5 for engagement with the sleeper. Formed at the outer ends of the arms G, are eyelets 7 for re ceiving nails 8 or other suitable fastening means which secure the ,sleepers 1 to the anchoring devices.

rlhe portions of the rods 3, located between the pairs of anchors 4, provide spacers 9.

ligidly secured to the rods 3, is a plurality ot' substantially parallel spacing elements 10` of separately formed supporting" devices 12 arranged in pairs and rigidly secured to a pair of substantially parallel spacing elements 13. Each of the supporting members 12 comprises a wire rod which is crimped to form a pair ot substantially il-shaped anchoring portions 14. The outer legs ot the anchoring portions 14 are bent to form projections 15 which are Welded or otherwise rigidly secured to the spacers 13. The inner legs of the portions 14 are bent to :torni seats 16 for engaging the sleepers 1 and these seat portions 16 are folded upon themselves to form arms 17 adapted to be bent so as to embrace the sleepers. Formed at the outer ends of the arms 17, are eyelets 18 :tor receiv ing nails 19 or other suitable fastening means, whereby the sleepers are secured to the,

anchoring devices.

for spacing the supporting members 12 the desired distances apart.

In the form shown in Fig. 7, the anchoring device comprises a unitary structure made of a single piece of Wire which isbent to form two pairs of anchors arranged iii substantially parallel spaced i'elation and connect-ed together by integral spacing elements 21. The inner legs of the anc-hors 2O are bent to forni seats 22 and fastening ai'ms 3 similar to `those shown in Fig. 6.

In operation, after the concrete has been poured and before it has set, the improved anchoring devices are placed on the slab as shown inlfull outline in Figs. l and 4. Aft-er the concrete has set, the sleepers are placed on the devices and the fastening arms are then bent upwardly to embrace the sleepers and to permit the nails to be driven into the sides of the sleepers.

In certain anchoring devices heretofore in use, the fastening arms Were Welded to the supporting structure. Such devices Were ob` jeetionable because, in bending the arms into operative position, the Welded joint Was frequently broken.` In the improved devicesv en'ibodying this invention, the fastening arms are formed integral with the anchoring portions so that the foregoing objection to prior devices is cured.

`Although but certain specific embodiments of this invention have been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted Without departing from the spirit of this invention as defined by the following claims.

I claim:

l. A device of the class described comprising a. sup-porting member having a seat poi'- tion adapted `to support a bar extending longitudinally of said member, portions on respectively opposite sides of said seat being bent to form anchors adapted to be embedded in a support, .said seat and anchors being located in a single plane, said seat having an integral portion bent to form an armV for attachment to the bar.

2. A device of the class described compris` ing a supporting member having a seat portion adapted to support aI bar extending longitiidinally of said member, portions on respectively opposite sides of said seat being bent to form substantially V-shaped anchors adapted to be embedded in a support, said seat having an integral portion folded upon liotself to form an arm for attachment to the 8. A device of the class described comprising a'supporting member having a .seat portion adapted to support a bar extending longitudinally of said member, portions on respectively opposite sides of said seat being crimped to form substantially V-sha ed anchors disposed in the plane of said seat adapted to be embedded in a support, said seat having an integral portion bent to form an arm for attachment to the bar.

4. A device of the class described comprising a wire member having ak portion thereof folded upon itself to form an arm adapted .to provide aI seat for a bar extending longi- .having arms for attachment to the bar, portions on respectively opposite sides of each of said seats being bent to form anchors adapted to be embedded in a support.

6. A device of the class described?comprising a pair of supporting members ar langed in substantially parallel spaced relation, said members having seat portions for supporting a bar, said seat portions havingl arms adapted to be bent transversely to said seat portions for attachment to the bar, portions on respectively opposite sides of each of said seats being bent to form anchors adapted to be embedded in a support, and a plurality of spacing elements connected to said supporting members and arranged at substantially right angles thereto.

7 A sleeper anchor comprising a Wire rod crimped at intervals to provide a plurality of spaced supports, a portion of said rod between adjacent supports forming a seat for supporting a bar extending longitudinally of said rod, said seat being folded upon itself to provide an arm having an'eyelet therein, and means adapted to project through said eyelet for securing said arm to the bar.

8. A floor sleeper anchor comprising a Wire rod crimped at intervals to provide a plurality of anchors arranged in pairs and adapted to be embeddedin a support, the portion of said rod between the anchors of each pair forming a seat for supporting a bar, each of said seats being folded `uponitself to provide an arm for attachment to the bar, the portions of said rod between said pairs of anchors being arranged to space said anchors apart longitudinally of the bar.
