Application filed June 19, 1925. Serial 110538343.

This invention relates to sockets or receptacles such as are adapted toform cavities in concrete and to receive th'erewithin bolts for securing various articles to such concrete material. It is the general purpose and object ofthe invention to provide a socket or receptacle or this character which may be conveniently applied to and-which will remain in the concrete, without displacement during the pouring of'the concrete mixture; also a socket which will remain firmly afiixed to the mold board or panel to which it is applied, enabling such'board or panel, with thesocket or sockets thereon, to be handled withoutdanger of'detachment; also to provide a socket'having a contour which will enable it'notonly to receive a bolt or lag screw, without the use of an expansion shield, but which will also enable the socket to be lockdor'anchored firmly in the concrete. Further and more limited objects of the invention will appear hereinafter; and the objects generally will be realized in and through the construction and arrangement Fig. 4 a view similar to Fig. 3 showing a bolt in the socket or receptacle securing a bracket to the molded concrete.

Describing the various parts by reference characters, 1 denotes the main or body part of the socket or receptacle, such body art having a thread 2 pressed therefrom. he inner end of the said socket or receptacle is provided with a frusto-conical head 3 while the outer end is formed into a pair of prongs 4 The prongs are preferably of such shape that sections therethrough taken at right angles to the axis of the socket or receptacle will constitute segments of a cylinder, there being V-shaped notches 5 provided between the edges of one prong and the edges of the adjacent prong. The prongs preferably constitute continuations of the main body of the socket or receptacle.

It will be noted that the base of each of the prongs 4 is approximately 180 in extent, thus affording a large anchorage for each prong in a mold board. To prevent further the prongs from being easily removed or displaced from a mold board, each prong is provided with a plurality of resilientwbarbs 6, preferably formed by striking V-shaped tongues" from the prongs,with the points of the tongues projecting toward the innerend 3 of the socket" or'receptacle.

In 'using a socket or receptacle constructed in the manner shownand described herein,

"the prongsare driven into a mold board 7 preferably beyond their junction with the -bodyof the socket, whereby a part of such body will be'embedded in the board. The

shape of the end 3 enables this end to-be used asa head or anvil for driving the prongs into the board, without injury to the socket. The

'- socket is firmly anchored to the board. 7

b 1 reason of" the large interlocking surface af fordedby the prongsand is prevented from being easily withdrawn'from the board by the barbs-or tongues 6. When the concrete 8 has set, the boards 7 may be removed from the sockets or receptacles attached thereto in the usual manner, the threads 3 bonding the sockets securely within the concrete. A bolt 9 may then be threaded into the socket or receptacle and used for securing any object to the concrete, such as the bracket 10, indicated in Fig. 4.

The socket shown and described herein is simple in construction and economical of production and is particularly well adapted for the purposes for which it is designed.

Having thus described our invention, what we claim is 2-- 1. A socket or receptacle for the purpose set forth comprising a tubular pocket closed at one end and having one or more prongs projecting from the other end thereof, each prong being curved in cross section whereby it may form a secure anchorage with the mold form.

, 2. A socket or receptacle for the purpose set forth comprising a hollow body having one or more prongs projecting from one end thereof. the opposite end of said hollow body being closed, each rong being curved in cross section and provided with one or more resilient barbs struck therefrom.

3. A socket or receptacle for the purpose 'set forth comprising a hollow body having one or more prongs projecting from one end thereof and having a frusto-conical head at the opposite end thereof, each prong being provided with one or more resilient projections.

4. A socket or receptacle for the purpose set forth comprising a tubular body having prongs at one end thereof constitutin segmental tubular extensions of said bo y.

5. A socket or receptacle for the purpose set forth comprising a tubular pocket closed at one end and having a pair of prongs constituting extensions of one end of said body, there being V-shaped notches provided between the said prongs and each prong having one or more resilient barbs struck therefrom.

6. A socket or receptacle for the purpose set forth comprising a tubular pocket closed at one end and having a thread therein for the reception of the thread of a bolt or screw, there being one or more prongs projecting from one end of said body.

7. A socket or receptacle for the purpose set forth comprising a hollow body having a thread therein for the reception of the thread of a bolt or screw, there being one or more prongs projecting from one end of said body, the opposite end of said body being provided with a frusto-conical head.

8. A socket or receptacle for the purpose set forth com risin a hollow body havin a thread therein for the reception of the thread of a bolt or screw, there being one or more prongs projecting from one end of said body, the opposite end of said body being provided with a frusto-conical head, each prong being provided with one or more an choring projections.

9. A socket or receptacle for the purpose set forth comprising a hollow body having a thread therein for the reception of the thread of a bolt or screw, there being one or more prongs projecting from one end of said body. the opposite end of said body being provided with a frusto-conical head, each prong being provided with one or more barbs struck therefrom.

10. A socket or receptacle for the purpose set forth comprising a tubular pocket closed at one end and having one or more prongs projecting from one end thereof, each prong being provided with anchoring means.

11. A socket or receptacle for the purpose set forth comprising a hollow body closed at one end and having a thread therein for the reception of the thread of a bolt or screw, said body being of such contour as to enable the same to be firmly anchored in a concrete mixture and having its outer end adapted to be secured to a mold board.

In testimony whereof, we hereunto affix our signatures.
