4 Claims.
:Thisinvention relates to fittings for use generally in'connection with sheet metal containers :andis herein illustrated in connection with a fire extinguisher, although it may, of course, be employed to advantage in many other instances.
The general objects of the invention are to providjed'fan improved metal fitting and an improved mei ttallic structure of which such fitting forms a 'pa.
Theinvention will be understood from the following description taken in connection with the accompanying drawing, in which Fig.1 is a-sectional view of the upper end of a sheet'metal container, showing an element of the present fitting, namely, a screw-threaded ring in position to'be attached to the container; Fig. 2 is'a View similar to that of Fig. 1 and showing an additional element of the fitting, namely, a locking ring positioned within the neck portion of the sheet-metal container preparatory to the executioner a die-forming operation by which the screw-thread ring, the neck portion of the container and the locking ring are secured together as elements of a metallic structure embodying the present invention, and Fig. 3 is a view similar to that of Figs. 1 and 2 and showing the screw-threaded ring, the neck portion of the container and the locking ring in a metallic structure produced in accordance with the present invention.
Referring to the drawing, the numeral I indicates a metallic wall, such, for example, as that of a fire extinguisher head ll, having in its prefinished state an upwardly extending flange-like neck ,portion l2 defining the usual opening through which accessto the extinguisher may be had.
It is'tothe'neck portion l2 that the elements of the present fitting, namely, an externally screw-threaded ring 14 and a locking ring l5, 'are'adapted to be attached by the present method so as 'to produce the improved metallic structure shown in Fig. 3.
According to the .present invention, the screwthrea'ded ring I4 is so shaped interiorly thereof that it presents at its lower end a downwardly and outwardly curved surface 16 which conforms to the curvature'of the sheet metal wall at the juncture of the neck portion I2 of that wall with the main or dome-like portion of the same when the ring is placed or positioned on the extinguisher head H as shown in Fig. 1. It is to be noted that the curved surface I6 terminates on a horizontal plane passing through the screwthreaded ring at a substantial distance above the lower end thereof, and that the ring is so shaped throughout its remaining interior area as to present a neck-receiving surface 17 which is inclined upwardly and outwardly, as reckoned from its juncture with the curved surface It, thus affording between itself and the outer surface of the neck portion l2 a substantially V-shaped channel or clearance, reference being had to Figs. 1 and 2.
As to the locking ring 15, it is to be noted. that its interior wall is initially such as to present a cylindrical surface [-8, whereas its peripheral wall is so shaped as to present at itslower margin a cylindrical surface 26 and at its upper margin an upwardly and outwardly inclined neck-engaging surface 2|, the angular inclination of which latter surface corresponds to that of the neck-receiving surface 11. Referring particularly to Fig. 2, wherein the locking ring I is shown properly positioned preparatory to its being permanently attached to the extinguisher head II, it will be noted that the outer diameter of the lower margin of the ring I5 is such as to permit that portion of the ring to be readily introduced into the neck portion 12 of the extinguisher to such an extent that the upper edge of the neck portion will engage the outwardly inclined neck-engaging surface 2! in the vicinity of the juncture of that surface with the cylindrical surface 20.
According tothe present invention, the screwthreaded ring l4 and the locking ring l5 are permanently attached to the neck portion i2 of thecontainer by forcing the ring 15 downwardly, under the action of a suitable press-actuated die or plunger 22, into forming or upsetting engagement with a suitable die 24, on which the extinguisher head [1 is supported during that operation and by which the lower margin of the ring is forced outwardly into intimate locking engagement with the sheet metal wall, as shown in Fig. 3, theneck portion l2 of the extinguisher being simultaneously flared or expanded intoengagement with the neck-receiving surface ll of the screw-threaded ring under the wedging action of the neck-engaging surface 2| of the locking ring.
It is to be observed that the upper marginal portion ofthelocking ring l5 retains its original shape and dimensions while the lower marginal portion of that ring is being forced into impinging engagement with the sheet metal wall H); but despite the fact that the upper marginal portion of that ring remains undistorted, it, by reason of the angular relation of its neck-engaging surface 2! to the neck-receiving surface ll of the screwthreaded ring l4, functions to exert and maintain an effective clamping action on the neck portion I2 of the sheet metal wall in the finished metallic structure.
In the form of the invention herein shown,
particular reference being had to the fire-extinguisher-embodiment of Fig. 3, the locking ring it is of such height that it protrudes a slight distance above the upper end of the screwthreaded ring M and there presents a seating surface 25 adapted to receive the gasket or sealing element, with which the usual fire-extinguisher-head-cap, not shown, is provided. It is to be noted that the locking ring l5, when employed in connection with fire extinguishers of the so-called acid-soda type, may be provided at its upper end with an internal shoulder or ledge 26, adapted to support the customary bottle-cage, not shown, within which the ordinary acid-retaining bottle is held ready to dump its contents as the fire extinguisher is inverted to condition it for use.
It will be understood that various departures may be made with respect to the article and the product herein described without deviating from the spirit of the invention or the scope of the following claims.
What is claimed is:
1. A metal fitting adapted to be attached to a metal wall having a flange-like neck portion extending upwardly therefrom, characterized prior to its attachment by a ring adapted to be placed about said neck portion and having an upwardly and outwardly inclined neck-receiving surface between which and said neck portion a channellike clearance is initially afforded and into engagement with which said neck portion is adapted to be outwardly distorted, and a locking ring adapted to assume clamping position within the first-mentionedring and having a lower marginal portion and an upper .marginal portion presenting an upwardly and outwardly inclined neckengaging surface having a contour conforming substantially to that of said neck-receiving surface, said upper marginal portion of said locking ring being adapted upon assuming clamping position with relation to the first-mentioned ring to impinge on and anchor said neck portion intermediate said neck-receiving and neck-engaging surfaces and the lower marginal portion of said locking ring being adapted to be distorted into a cooperative relation to the first-mentioned ring to retain said locking ring in clamping position.
2. A metal fitting adapted to be attached to a metal wall having a flange-like neck portion extending upwardly therefrom, characterized prior to its attachment by a ring adapted to be placed about said neck portion and having interiorly thereof an upwardly and outwardly inclined neck-receiving surface between which and said neck portion a substantially V-shaped channel-like clearance is initially afforded and into engagement with which said neck portion is adapted to be outwardly distorted, and a locking ring adapted to assume clamping position within the first-mentioned ring and having a lower marginal portion so dimensioned as to permit it to be unobstructedly introduced into said neck portion and an upper marginal portion presenting on its outer face an upwardly and outwardly inclined neck-engaging surface shaped to conform substantially to the contour of said neck-receiving surface and so dimensioned as to distort said 5 neck portion and move it outwardly into engagement with said neck-receiving surface upon movement of said locking ring-to clamping position, said upper marginal portion of said locking ring being adapted upon assuming clamping po- 10 sition with relation to the first-mentioned ring to impinge on and anchor said neck portion intermediate said neck-receiving and neck-engaging surfaces and the lower marginal portion of said locking ring being adapted to be distorted into 15 a cooperative relation to the first-mentioned ring to retain said locking ring in clamping position.
