Application October 5, 1934, Serial No. 747,024 .5 Claims. (01. 29-1483) This invention pertains to metal barrels and similar containers, and more particularly is a method by which such container may be provided with a suitable opening for any desired purpose, particularly where it is desirable that such an opening be closed by a screw plug or similar closure element. I g
It is well known that the walls of metal drums, barrels and similar containers are usually entirely too thin to permit of screw threading to a sumcient degree to receive and retain a removable closure plug. I have overcome this difflculty by providing a process whereby such a container may be provided with an opening possessing the thickness of metal suflicient to provide ample screw thread anchorage for a re movable plug, and it is therefore the object of this invention to provide a process by means of which the above result may be effectively and economically accomplished.
The invention will be hereinafter fully set.
forth and particularly pointed out in the claims.
In the accompanying drawings, Fig. I isa cross sectional view illustrating a plug-receiving member constructed and arranged to be securedto a drum barrel or the like. Fig. 2 is a similar view showing the plug-receiving member initially engaged with a flange formed arouhd an opening in a container of the type mentioned. Fig. 3 is a similar view to Fig. 2 illustrating another stage of the process of uniting the plug-receiving member 'to the wall of the container. Fig. 4 is a similar view illustrating the plug-receiving memev ber in its final position. Fig. 5 is a side elevation illustrating the method of crimping the exterior of the plug-receiving member to prevent rota-' tion thereof with respect to the wall of the container. Fig. 6 is a vertical sectional view on the line 66 of Fig. 4.
Referring to the drawings, P designates a plug-receiving member constructed of metal and provided with a central screw threaded opening l0. Said member is also provided with an annular groove'll having an inner flange I 2 and an outer flange l3 on the opposite sides thereof.
It will be noted that in Fig. 1 the flange I3 is shown in a slightly divergent position and is provided with an enlargement l4 at its edge. The drum barrel'or other container is indicated at B, the same being provided with an opening I5 formed by pressing the metal outward so as to form an annular flange IS, with inturned edges l1.
In practice, a blank such as indicated in Fig. 1, is engaged with the flange l6, by causing the flanges l2 and I3 to straddle said flange l6, 9. suitable packing C having first been placed upon the inturned edge I! of the flange IS. The parts are then held in suitable manner and the flange I2 is bent outwardly, as indicated at 18 of Fig. 2,
upon further pressure is applied in a direction tending to squeeze the packing C, in such manner as to spread it overthe bottom of the groove II, and to also squeeze the bent portions l1 and I8 and the flanges I3 and It more closely together, as indicated in Fig. 4. After this operation, the parts are so secured together that they become practically an integrel unit. Out of an abundance of caution, to prevent relative rotation of the part .P with respect to the part B, a radial crimping pressure is applied so as to provide the inwardly crimped portionsZfl in ,the flange l3, which are of suflicient magnitude to slightly 01T- set the flange "5, as clearly shown in Fig. 6, thereby providing a definite interlock between the plug-receiving member and the container.
The advantages of the invention will be readi- 1y appreciated by those skilled in the art to which it belongs. For instance, it will be particularly noted that the member P may be made of sufli- -cient thickness to provide ample surface for a screw thread, and therefore provides a simple and with a removable screw plug closure. It will also be observed that the parts are so intimately connected with eachother that they constitute to all intents and purposes an integral structure and will not become loosened or separated.
Having thus explained the nature of the invention and described an operative manner of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of. the forms of its efficient means of equipping a metal container inturned edge of the container flange and then squeezing all of said flanges together.
2. The method of attaching a plug-receiving member to a container, comprising forming a hole in the container and forming a flange around said hole, providing a plug-receiving member having concentrically spaced inner and outer annular flanges, engaging said member with the container flange in such manner that the latter isinterposed between the flanges of said member, interposing a packing washer between the container flange and said member, bending the container flange and the inner flange of the plugreceiving member into parallel relationship, bending the outer flange of thecontainer member into engagement with said container flange, then compressing all of said flanges into engagement by movement of the plug-receiving member toward the body of the container, and then crimping portions of said outer flange radially inward to a suificient extent to correspondingly ofl'set portions of the container flange so as to hold the parts against relative rotation.
3. The method of attaching a plug-receiving member to a metal container, comprising providing the container with a hole having a flange surrounding the same, said flange: having an inwardly bent edge, providing a plug-receiving member having concentrically spaced inner and outer flanges, engaging said member with the flange of the container in such manner that the flanges of the plug-receiving member straddle the flange of the container, bending the inner flange of said memberin a manner to overlap the inturned edge of the container flange and then squeezing all of said flanges together, and pressing radially inwardly spaced portions of the outer flange to such an extent'as to interlock with and slightly oil'set adjacent abutting portions of the container flange.
4. The method of attaching a plug-receiving member to a metal container which comprises.
