In the construction here proposed there are numerous advantages both from the standpoint of manufacture and use... The wire elementis the same'as thatof my previously disclosed construction and is simply The sheet made in an automatic machine. metal; parts are more simply made and the assembly is quickly-accomplished in-a suit.- able machine. In the use" of the device the advantages are apparent, no difliculties beingi encountered because of the necessity for.

bendingjthe metalg Thus the breakage resulting; from repeated bendings is avoided. Because the desired result'is securedflwithjout bendin gthermetalleam enabled to use sheet metal of heavier gauge andthereby increase the efficiency of the device by avoiding the tearing out of the fastening nails.

The invention will be more readily understood by reference to the accompanying drawings, wherein,

- Fig. 1 is a transverse sectional view through a body of concrete'showing the application of my sleeper anchor thereto;

Fig. 2 is an enlarged elevation of the" device;

vFig. 3 is a sectional view on the line 33 of Fig. 2, and,

Fig. 4 is a plan view thereof.

In the drawings it will be seen that the device comprises essentially an anchor element consisting of a length of wire bent to provide V-shaped side portions 10, 11, joined at the upper extremities of the Vs by horizontal portions 13 which lie parallel to and at thesurface of the concrete A, shown in Fig. 1. o The connecting portions 13 are joined by a strip of metal 14, the ends of which are hooked or crimped into cylindrical form. This strip acts to prevent.

the device is of extreme simplicity and? its use does not involve the bending'of" the material composing the wings. This enables the use of slightly heavier material and eliminating the'connecting strip14; and that construction is contemplated under some 'cir-y' This and other ;modifications I cumstances. consider within the scope of my invention. i

In the claims the word hinge is used in order to provide means of attachment to a sleeper; Y I

2. In a device of the class described, the combination of a pair of anchor elements and cylindrical connecting members, and wings hinged to. said connecting members and adapted to be disposed in a position flat on a cement surface or perpendicular thereto in order to provide means of attachment to'a sleeper, and'means for tying to gether said cylindrical members and serving also as a stop for limiting the extent of avoids the possibility of tearing out-of the I nails after the installation of; the, sleepers.-

Much the same results may be secured by in its accurate sense andis intended to distinguish over a constructlon 1n whlch a hinge "also as a stop for limiting theextent of insertion of said anchor elements in the cement, the ends of said tying members being bent over the hinge of said wings.
