JOHN JOSEPH RAWLINGS, OF LONDON, ENGLAND, ASSIGNOR OF ONE-HALF TO THE RAWLPLUG COMPANY LIMITED, OF LONDON, ENGLAND, A CORPORATION OF GREAT BRITAIN.
PLUG OR SOCKET FOR RECEIVING SCREWS OR LIKE FASTENINGS.
Application filed August 22, 1921. Serial No. 494,424.
To all whom it may concern:
Be it known that 1, JOHN J OSEPH RAW- LINGS, a subject of the King of Great Britain, residing at London, England have invented a new and useful Improved Plug or Socket for Receiving Screws or like Fastenings, of which the following is a specification.
This invention relates to an improved construction of tubular plugs or sockets intended to be inserted in prepared holes in stone, brick, concrete or other hard substances and adapted to receive screws or the like by which articles can be firmly secured in desired positions.
According to this invention tubular plugs or sockets for the purpose above indicated are made from soft metal such as lead by a known method of extrusion through a'die, the finished plug having a form consisting of a number of more or less cylindrical shaped parts or rods united by webs, thus providing a tube having internal and external longitudinal channels extending from end to end thereof. After extrusion through the die the plugs are cut off to any desired length. a
The invention also comprises the combination with such soft metal tubular plug of a number of wires made preferably of hard metal embedded longitudinally in the cylindrical shaped parts or rods of the plug in order to increase the tensile strength of the plug and to prevent a screw when screwed therein from working too much to one side.
My improved plug is illustrated in the accompanying drawing on an enlarged scale.
Figure 1 is a transverse section, and
Figure 2 a side view of the plug.
Figure 3 is a transverse section, and
Figure atis a central longitudinal section showing a similar plug having hard wires incorporated in it.
The plug is made by e. lead, through a die in the usual well known manner where a tubular article has to be produced, the die being shaped to give to the plug the form shown in Figure 1, that is to say, a series of more or less extruding soft metal,
cylindrical shaped parts or rods A united by webs B. After extrusion, the plugs are cut off to the desired lengths. When such a plug is inserted in a cylindrical hole in any hard material, and a tapered screw, nail or like fastening is screwed or driven into the central hole C of the plug for the purpose of fixing an article thereto, the metal of the plug is caused to flow laterally into the longitudinal channels D, D thus producing a considerable deformation of the shape of the plug, which allows the screw or nail to be driven well home and a powerful grip to be obtained. a
-When hard metal Wires are to be incorporated with the plug, the ends of these wires E are supported in suitable positions within the die so that the extruded metal on its passage through the die envelopes the wires and draws them along with it.
These wires E give added tensile strength to the plug, and also serve to prevent the fastening screw or nail from working too much to one side of the plug when it is bein driven home.
' hat I claim is:
1. A plug or socket made of soft metal, comprising a plurality of cylindrical shaped parts arranged side by side to form a tube, said parts being united at their points of contact by longitudinal webs extending the whole length of the tube, thus providing internal and external longitudinal channels between the said cylindrical parts.
2. A plug or socket made of soft metal, comprising a plurality of cylindrical shaped parts arranged side by side to form a tube,
said parts being united at their points of contact by longitudinal webs extending the whale length of the tube, thus providing internal and external longitudinal channels between the said cylindrical parts, and a hard metal wire within each cylindrical part and extending the whole length of the tube.
