This invention relates to a device foir rlgidly securing sleepers to concrete floor foundations in order that wood flooring may be readily secured theretot I A main object of my'invention is to provide a simple device in which the anchoring members are readily insertible in concrete before the same is set, and in which the sleeper attaching members are pivotally at-- tached thereto, whereby the attaching memto a horizontal position in contact with the concrete foundation when not in use.

A further object is to provide 'a device in which the anchoring members may be readily adjusted to receive sleepers of vary: ing widths.

A still further object is to provide a device that is of simple construction, and that may be formed of inexpensive materials.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawings forming a part thereof, 'in which Fig. 1is a cross section of a concrete floor showing a pair of sleeper anchors embedded therein, sleeper attaching members of one anchor being folded-and the other anchor device secured to the sleeper.

Fig. 2-is an enlarged end elevation of an anchor device embedded in a concretefloor with a sleeper secured thereto,the dotted lines indicating the method of adjusting the anchor members for sleepers of greater dimensions.

Fig. 3is a perspective view of one of the devices.

Fig 4is a side elevation of an anchor device with a sleeper attached thereto.

Referring to the drawings, and especially to the perspective view shown in Fig. 3, it will be seen that the anchoring device 5, is formed from a single length of wire bent into the form of an elongated closed loop, the ends of which are laterally bent into parallelism and constitute anchors 7 adapted to be embedded in a concrete floor 8. Hingedly secured to each of the interme-, diate portions 9, 10,'of the anchoring mem bers are sleeper attaching members 11, each preferably formed of galvanized sheet metal of a sufliciently heavy gauge to prevent accidental deformation, and bent upon itself to form a hinge bearing 12, in order that the attaching members may be swung into a' vertical or horizontal position, the latter po-' sition being]desirableprior to the attach-v ment of the sleeper members 13 thereto as when in such position they will offer noobstructionsto the passage of wheelbarrows thereon during construction operations. The two portions of the flat attaching members are secured together by spot welding,- and each are provided with openings 15 for the passage of nails therethrough for securing the same tothe sleepers. H In Fig. 2 the anchor device is shown on an enlarged scale attached to a sleeper, the distance between the intermediate portions 9, 10, of the loop anchoring member being substantially the same as the width of the sleeper 13 attached thereto. By securing the attaching members in this manner with the cylindrical hinge bearings 12 disposed beyond the side faces of the sleeper the bottom face of the sleeper will rest upon the surface of the concrete floor or foundation. Frequently the width of the sleepers used may be greaterfthan the width between the attaching member s, thus if the anchor devices were designed to carry two by four inch sleepers and it was desiredto use three by four inch, the intermediate portions 9 and 10 may be readily stretched apart, as clearly shown in dotted lines in Fig. 2, to

, receive such sleepers. I

I By formingthe anchor members 7 in V- shaped form, it will be apparent that they may be readily inserted into the wet concrete, and further as space between the intermediate portions 9 and 10 is open, the concrete between the. same may be quickly tamped, thus insuring a complete embedment of the anchor members, this feature 9 constituting one of the important advantages of the device.

What I claim is: p A sleeper anchor consisting of a single length of readily bendable wire bent into the form of an elongated closed loop, theends of said loop being bent at right angles in parallelism, and a flat sheet-metal sleeper attaching plate movably secured to each of the side members of the loop, the side members adapted to be moved to or from each" other, whereby the distance between the attaching members may be quickly adjusted.

" In witness that I claim the foregoing I have hereunto subscribedmy name this 10th day of February, 1926. V H H H CLAUDE E; BGWFJRS;
