SOCKET FOR EXPANSION-BOLT SHIELDS.

Application ined :une 19,1925. serial No. 38,144.

This invention relates to sockets or receptacles such as are adapted to form cavities in concrete and to receive bolts therewithin. In the form of the invention which is shown herein, the socket or receptacle is adapted for the reception of an expansion shield and its bolt. v

It is the general purpose and object of the invention to provide a socket of this character which may be conveniently applied to and which will remain in the concrete; also a socket which, while being particularly well adapted for use with concrete oorings, may be also used in connection with concrete walls other than loorings. i

We accomplish the foregoing objects and other and more limited objects (to be set forth hereinafter) intand through the construction and arrangement of parts .shown in the drawings, wherein Fig. 1 represents a side elevation of a socket constructed in accordance with our invention, illustrating the manner in whichpit is applied to a concrete floor, the concrete being shown in section; Fig. r2 a vertical sectional view through the socket, showing the concrete; Fig. 3 an elevation of the socket shown in the preceding views; and Fig. 4 a view, similar to Fig. 2, showing the socket applied to a mold board. i

Describing the various parts by reference characters and in connection with Figs. 1-3 inclusive, the socket comprises generally a body 1 which radually expands in crosssectional area rom the outer end thereof toward the inner end, the extreme inner end portion 2 being conical. The outer end of the socket is provided with a flange 3 at right angles to the axis thereof, the ,said flange being provided with a plurality of apertures 4 therethrough which are adapted to receive nails or screws.

In the use of our socket or receptacle with concrete flooring, when the concrete is laid the socket is pushed down into place, as shown in Figs. l and 2, with the flange 3 resting on the concrete. The action of inserting the socket into the concrete 5 is facili tated by 'the conical shape of the end 2 thereof, while the increasing cross-sectional area of the part l from the outer end inwardly enables the socket or receptacle to be retained firmly within the concrete when the latter has set. Furthermore, the conical end 2 provides a tapered wall against which the inner end of the expansion bolt shield may abut while the boltis being set up and thus prevent the turning of the shield within the socket or receptacle.

In Fig. 4, our socket is shown in use with a molded concrete wall or body 5, in which case the flange 3 is secured tothe mold membei 6 by means of nails or screws 7 the former being indicated. When used in this manner, after the mold boardsor panels are set up, with the sockets or receptacles applied thereto, the concrete is poured in the usual manner. When the concrete is set, the boards or panels 6 are pried loose from the molded wall, leaving the sockets in place.

The socket shown and described herein is simple in construction and economical of production, while entirely capable of accomplishing the purposes for which it is designed.

Having thus described our invention what we claim is 1. A socket for the puropse set forth comprising a hollow body which is of gradually increasing cross-sectional area from the outer end toward the inner end and having a pointed or conical inner end, the outer end of the body being provided with a ange extending at substantially right angles to the axis thereof.

2. A socket for the purpose set forth comprising a hollow body which is of radually increasing cross sectional area rom the outer end toward the inner end and having a pointed or conical inner end.

3. A socket for the purpose set forth comprising a hollow body which is of increasing cross-sectional area from the outer end toward the inner end thereof andwhich is provided with a conical inner end, the outer end of the body having a flange projecting body having a flange projecting at substantially right angles thereto and adapted to be secured to u mold board or panel. 10 In testimony whereof, We hereunto afix our signatures.
