LOCK SEAMED SPUD Filed Jan. 12, 1957 INVENTOR wl-ruzsy.
ATTORNEYS Patented Jan. 16, 1940 UNITED STATES PATENT OFFICE LOCK SEAMED SPUD Illinois Application January 12,1937, Serial No. 120,316
2 Claims.
The invention relates to a spud construction and more especially to a lock seamed spud.
The primary object of the invention is the provision of a spud of this character, wherein through the construction thereof the same can be placed in the opening of a metal tank and lock seamed therewith in a manner that the spud can not be knocked out, turned and will be positively leakproof.
Another object of the invention is the provision of a spud of this character, wherein either a plug or a cap can be fastened in place for the sealing of the opening accommodating the spud.
A further object of the invention is the provision of a spud of this character, which is simple in construction, susceptible of being lock seamed with a tank so as to render the seam leakproof, strong, sturdy, neat in appearance, and inexpensive to manufacture and install.
With these and other objects in View, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claims hereunto appended.
In the accompanying drawing:
Figure l is a top plan view of a capped spud constructed in accordance with the invention and lock seamed with the body of a tank.
Figure 2 is an enlarged sectional view on the line 22 of Figure 1 looking in the direction of the arrows.
Figure 3 is a fragmentary sectional view similar to Figure 2 showing the spud in position prior to lock seaming the same with the tank.
Figure 4 is a view similar to Figure l with the cap removed.
Figure 5 is a view similar to Figure 3 showing the spud when initially inserted in the hole or opening in the tank.
Figure 6 is a fragmentary sectional View similar to Figure 2 showing a modification with a plug inserted in the spud.
Figure '2 is a fragmentary vertical sectional View showing a modified form of spud.
Figure 8 is a view similar to Figure 7 showing a further modification of spud.
Similar reference characters indicate corresponding parts throughout the several views in the drawing.
Referring to the drawing in detail, particularly Figures 1 to 5 inclusive, A designates generally a portion of a metal tank having a suitable opening for the filling of such tank or the (o1. ass-49y discharging of its contents and mounted in this opening is the spud B constituting the present invention and hereinafter fully described.
The spud B comprises an annular or ring-like body In made from metal and of a height suflicient for a required number of threads ll both internally and externally thereof .for the fittin of a cap l2 thereon. This can l2 carries a sealing gasket l3 which rides the top of the body Ill and is confined within a seat ll within the cap between an outer peripheral rim l5 and the center body portion l6 thereof so that when the cap is screwed home a fluid-tight closure will be had for the opening in the tank A.
The body 10 of the spud B is formed with an external annular outstruck flange H for seatin within a countersunk recess 18 formed by an in-bent circular shoulder is instruck from the edge of the opening in the tank A. The flange I! in its bottom face is formed with an annular channel 20 for a packing ring 2| which has contact with the shoulder I9 to effect a. leakprooi joint between the flange and said shoulder.
The body l0 below the flange I! is formed with a depending circular shaped bendable skirt or a relatively thin bendable annulus 22 constituting an extension of the body while augmenting the shoulder I9 is an annular seaming extension 23 which is of considerably less extent than the annulus 22 so that the latter can be folded over the said extension 23 and thence the folded over portion of the annulus 22 and the extension 23 bent outwardly and upwardly against the under side of the shoulder I9 thereby effecting a lock seamed connection between the spud B and the tank A as will be clearly apparent from Figure 2 of the drawing.
This lock seaming of the spud on the tank A will eiiect a leakproof joint therebetween at the opening in the tank A and also will prevent the spud from being knocked out or turned or otherwise accidentally separated from the tank.
Within the hollow head of cap H are upstanding spanner wrench lugs, shown at 21. These may be engaged by any suitable spanner wrench or similar tool for tightening down or removing the cap.
In Figure 6 of the drawing the spud C, which is identical to the spud 13, has threaded therein a closure or sealing plug 28 which is internally threaded to the spud. This plug has a laterally extending flange 28a underneath which is carried a gasket 28b. This gasket seals the opening by being pressed between flange28a and the top face of spud C.
2 are-mos In Figure '7 of the drawing there is shown a slight modification oi spud wherein the lock seaming oi the body 28 of such spud with the tank 30 is identical to that hereinbefore set forth while this body of the spud 29 is turned outwardly and downwardly on itself at 3| and is internally screw threaded at 32. The outwardly and downwardly turned portion 3| oi the body 29 has contact with a sealing gasket 33.
A still further modification is shown in Fig. 8 of the drawing wherein the body portion of the spud is shown as thickened at 34 and as having the lower part or the thickened portion received within the countersunk seat around the opening in the container or tank A. The bottom surface or this thickened portion is shown as formed with a gasket receiving recess or depression 35, between which and the shoulder of the countersunk seat is received a sealing gasket 38. In this construction also, the portion of the spud, which is lock-seamed with the container wall, extends directly down in line with the root of the internal threads 31. By employing this latter expedient as well as providing the thickened portion 34 in place of flange H, as shown in the form of Figs. 1 to 6, a somewhat more compact construction is provided.
It is, of course, understood that the invention before described is not limited to a complete double seaming of the spud and stock because it is contemplated, if found necessary, to form mutilations in the seaming. at determined intervals thereof for the better draining of the contents of a container and also to better secure the spud. This mutilation may be effected at one or more places in the seaming of the stock and be thus effected by having the turned portion of the body shorter than the seaming skirt of the spud so that when the spud and body stock are seamed together there will be cut out places in the spud and stock.
The bendable skirt 22 01' the spud can be bent outwardly and upward y against the under side of the shoulder is without the presence 0! the extension 23 or this extension may be made the same length as the skirt 22 of the spud. Furthermore, corrugations at intervals around the seaming may be formed, this being effected by a tool active on the extension and the skirt when together.
By eliminating the skirt 22 from the spud the latter can be used as an electric or acetylene welded enclosure.
It is contemplated to thread the spud internally and also that said spud be made by turning the steel outwardly and downwardly to form a shoulder with one or more cut-out portions to give such shoulder an uneven line and thus producing a countersunk seat and in this manner the spud occupying the countersunk seat will be kept from turning.
What is claimed is:
1. In structure of the class described, a container wall having an opening therein with a countersunk seat therearound and a neck extending from said seat, a spud having a portion embraced by said countersunk seat and a portion extending from said embraced portion, said extending portion and said neck being interlocked and folded over to form a joint underlying and reinforcing said countersunk seat.
2. In structure of the class described, a container wall having an opening therein with a countersunk seat therearound and a neck extending from said seat, a spud having a returned bent portion embraced by said countersunk seat and a portion extending from said embraced portion, said extending portion and said neck being interlocked and folded over to form a Joint underlying and reiniorcing said countersunk seat.
