Application filed February 4, 1924.- i Serial No: 690,546;

T 0 all whom z't may concern.

Be it known that I, JOHN EDWARD ABLER, a citizen of the United States of America, and a resident of the city of Guelph, in the county of lVellington, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Screw Sockets for the Necks of Flexible Containers, of which the following is the specification.

My invention relates to improvements in filler sockets for rubber or compound containers, and the object of the invention is to devise simple means which will absolutely prevent the turning of the socket in the neck of the container or prevent it becoming loose owing to the heating of the material by the hot water in the container, and it consists essentially of a metal screw socket and means forming projections extending from the periphery of the socket and connected thereto and embedded in the material so as to form a secure lock, preventing the turning of the socket within the neck, all as hereafter more particularly described.

Fig. 1 is a perspective view of the neck portion of a flexible container, the wall of the neck being broken away to exhibit my socket.

Fig. 2 is an enlarged cross sectional view through the socket neck and my locking device.

Fig. 3 is a plan sectional view on line 33, Fig. 2.

Fig. 4 is an enlarged perspective detail of my locking member as it appears before being connected to the socket.

In the drawings like characters of reference indicate corresponding parts in each figure.

1 indicates the neck of a flexible container. 2 indicates the socket which is secured in the neck of the container.

3 is a plate which is annular in form, the central orifice of which is turned up into an annular flange 5 and spun into the bottom orifice 2* of the socket. The plate 5 is provided with a series of radiating arms 6 which are bent upward parallel with the face of the socket wall, and in which a series of inwardly extending projections 7 are formed either by punching in the metal or by any other suitable means. Softened rubber or other compound is run around the socket so as to flow in between the arms 6 and the wall of the socket, the projection 7 forming spacing means and permitting the material to flow freely into the interspace.

The socket is then inserted in the neck of the container and vulcanized therein, the plate 3 being spun into the bottom orifice, and the socket securely holds such plate in position so that the socket cannot turn in the surrounding material, and the arms 6 extending upward parallel to the walls of the socket, forming projections or ribs embedded in the material extending between the socket and the outer face of the container neck, absolutely preventing the turning of the socket within the material.

That I claim as my invention is:

1. In a container formed of flexible material or compound, the combination with the neck and screw socket, of means extending longitudinally of and from end to end of the socket and in spaced relation thereto for preventing its turning within the neck of the container.

2. In a container formed of flexible material or compound, the combination with the. neck and socket, of an annular member engaging concentrically with the lower end of the socket, ribs extending longitudinally of the socket and carried by such annular member at one end so as to be in spaced relation to the outer periphery of the socket and embedded in the material located between the exterior periphery of the socket and the neck of the container.

3. In a container formed of flexible material or compound, the combination with the neck and the socket inserted in the neck, of strips extending vertically of the socket adjacent its exterior surface, means for securing the strips in position in relation to the socket, and projections extending inwardly from the inner face of the strips for spacing said strips from the surface of the socket.

4. In a container formed of flexible mate: rial or compound, the combination with the neck and socket, of an annular plate having its inner edge spun upward into the central bottom orifice of the socket and having fingers extending from its outer periphery adapted to be bent upx ard against the exterior wall of the socket and to be embedded in the rubber and located between the exterior face of the socket and the exterior face of the bottle neck.

5. In a device of the class described, a socket locking member comprising an annular plate adapted to be secured at its inner periphery to the bottom of the socket, and provided With radial fingers extending outwardly therefrom, adapted to be bent iup- Ward against the exterior surface of the socket.

6. In a device of the c1as s described, a socket locking member comprislng an annular plate adapted tobe secured at its lnner periphery to the bottom of the socket and provided with radial fingers extending outwardly therefrom adapted to be bent up- Ward against the exterior surface of the socket, and projections extending inwardly from the fingers spacing the fingers from the exterior surface of the socket.

JOHN EDWARD ABLER.
