Dec. 25, 1928 'r. J. SENESAC ANCHOR FOR FLOOR SLEEPERS Filed Oct. 21,- 1927 Patented Dec. 25, 1928.

UNITED STATES PATENT OFFICE.

ANCHOR roza FLOOR SLEEPERS.

vApplication filed October 21,1927. Serial No. 227,670.

The main objects of this invention are to provide an improved form of bar support; to provide an improved bar support and spacer particularly adapted for use in concrete construction work; to provide, a device of this kind which is particularly adapted for use in supporting floor sleepers; to provide improved means for anchoring the supporting means in the concrete; to provide improved fastening means for securing the sleepers to the supports; and to provide a device of this kind which combines the supporting, anchoring, spacing and fastening means in a durable unitary structure, wherein the joint between the anchoring and spacing means is spaced from the fastening means so as not to be broken when the fastening means are bent into engagement with the sleeper.

Illustrative embodiments of this invention are shown in the accompanying drawing, wherein:

Figure 1 is a vfragmentary vertical section of a concrete slab on which a sleeper is supported by means of an improved anchor, the dotted outlines representing the fastening means in their operative positions.

Fig. 2 is a perspective of a sleeper supported on the anchoring device shown in Fi 1.

' Fig. 3 is a fragmentary perspective of one of the anchors shown in Fig. 2.

Figs. 4 and 5 are views similar to Fig. 3, but showing modified forms of anchors.

In the forms shown, the improved anchors are used for supporting floor sleepers or bars 1 on a concrete slab 2. Floor sleepers are generally disposed in substantially pare allel spaced relation to one another to form a wooden frame structure to which the customary floor boards are nailed. V

In the embodiments illustrated, the improved anchoring devices comprise a spacing member having secured thereto a supporting member provided with anchoring portions adapted to be embedded in the concrete and having fingers forming fastening means for attachment to'the sleeper. The improved anchoring devices may be made of any suitable material but are preferably formed of wire rods which may be bent to the desired shape.

In the form shown in Figs. 1, 2 and 3,

each of the devices comprises a spacing rod 3 having a plurality of supporting members 4 secured thereto at regular intervals.

vices, the fastening Each of the supporting members 4 comprises a pair of substantially V-shaped anchorlng portions 5 arranged in substantially the same plane and having their inner legs connected together by a shelf portion 6, which is spot-welded or otherwise rigidly secured to the spacing rod'3. The outer legs 7 of the anchoring portions 5 are preferably disposed substantially parallel to each other as shown in Fig. l.

The outer legs 7 of the anchoring portions 5 are longer than the inner legs, so as to provide fingers 8 adapted to embrace the sleeper 1. Formed at the outer ends of the fingers 8, are eyelets 9 to receive nails 10, which are driven into the sides of the sleeper for securing the latter to the anchoring device. In the manufacture of these improved devices, the fingers 8 are bent downwardly, as shown in full outline in Figs. 1 and 3, with the bend 11 located slightly beyond the spacing rod 3, so as to necessitate straighten ing of the fingers in attaching the sleepers.

In certain anchoring devices heretofore in use, the fastening fingers were welded to the spacing rod at the pointof, bending. Such devices were objectionable mainly because, in straightening the fingers into their operative positions, the welded joint was frequently broken. In these improved defingers 8 are not connected to the spacing rod 3 and their base portions are free to move alimited distance relative tothe spacer. With this improved arrangement of parts, there is no possibility of breaking the welded joint between the members through the bending of the fingers.

The shelf 6 and the portion of the spacer 3 which is located between the fingers 8 provide a seat for the sleeper and this seat may be varied in size by ward or away from each other.

In the construction shown in Fig. 4, the device comprises a spacing rod 12 having secured thereto supporting members 13 of modified form. The member 13 comprises a wire rod bent to form a pair of anchoring portions 14 arranged in different planes and connected by a shelf portion 15 which is P disposed at substantially right angles to the spacer 12. In this construction, the outer legs of the anchors 14 are located in substantially the same plane and are provided with fingers 16 similar in form and arrangement to those shown in Figs. 1, 2 and 3. I

The device shown in Fig. 5 comprises a moving the fingers to- V spacer 17 having secured thereto a plurality of supporting members 18 which are substantially similar to the one shown in Fig. 4. However, in the modification illustrated in Fig. 5, the spacer 17 is disposed at substantially right angles to the supporting members 18 so as to extend lengthwise of the shelf portions 19.

In operation, after the concrete has been poured and before it has set, the improved anchoring devices are placed on the slab with the anchoring. portions embedded in the concrete and the spacers resting on top of the slab as shown in Fig. 1. The devices are arranged so as to position the spacers in substantially parallel relation to one another at the desired intervals. After the concrete has set, the sleepers are placed on the seats defined by the flexible fingers and the latter are then bent upwardly to embrace the sleepers so as to permit the nails to be driven into the sides of the sleepers. In the forms shown in Figs. 1, 2, 3 and a the sleepers are disposed at substantially right angles to the spacing rods, whereas in the form shown in Fig. 5 the sleepers extend longitudinally of the spacers. I

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that certain details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.
