Patented July 9, 1935 i UNIF-TED?. STATES PATCH Earlfunis, Amsterdam, N. Y. maplimtimrs'e'pmnberV 5, 193s, serial-N0. 688,248

` zolaims. `(01.137-99) This invention relates to an improved patch and is particularly adapted for use in mending pots, pans,hot"water bottles and the like. f

One object of the invention is to provide a patch which will be so formed that thesealing disk employed therewith Vwill uniformly engage the surface to be patched so that danger of leakage at a point or points will be largely eliminated.

Another object of vthe invention is to provide ay a patch which will be characterized by the utmost simplicity and greatest efficiency so that, after mounting in place, it will effectually close a leak and will not require'further attention after installation.

- And astill. further object of the invention is to provide adevice of this character whereinthe upperend of the shank may be embedded in the head so that a smooth upper surface for th head will be accorded. Y i

, Other and' incidental objects of the invention, not hereinabove discussed, will .be lapparent as the description Vof thel invention proceeds.

My invention is illustrated in the accompanying drawing wherein Figurev 1 is a fragmentary vertical sectional view of my patch in the processA of construction and showing the shank extending through the head,

Fig.,2\is 'a vertical sectional view showing the device with the shank in position on the head during the process of upsetting'the ribscarried on said shank, l.

Fig. 3 is a' Vertical sectional view .,of my completedpatch and vshowing the same in position on a surface to be patched,

Fig. 4 is a vertical sectional view showing a slightly modified form of my invention,

Fig. 5 is a side elevational view showing the stud employed before being upset upon the head,

Fig. 6 is a bottom plan view of the stud, Fig. 7 is a vertical sectional view showing a further modification of the invention,

Fig. 8 is a. top plan view of the device as shown in Fig. 7, and

Fig. 9 is a fragmentary vertical sectional vview showing a still further modified form of the invention.

Referring now more particularly to the accompanyingdrawing wherein like numerals of reference designate like parts throughout the several views', the numeral I indicatesv the head of my improved patch whichY is preferably formed of a strong aluminum alloy andwhich is concave-convex in shape, the circumferential edge'of said head being straightened, as indicated at 2. The head is4 apertured and pressed inwardly to dene an annular seat 3. .It is emphasized that the head of the patch is made of an alloy of aluminum instead of tin plate or other rustable metal, so that danger of rusting and ruining of the patch will be eliminated. The head may also be'stamped from a single sheet of metal and formed into the desired shape with 'the seat 3 formed therein. This may be done by a single stamping operation, if so desired, so that the heads mayfbe'stampedoutin great quantities at a minimum cost.

Carried by the head I is a stud which is indicated in general bythe numeral 4. The Studis provided with an enlarged top portion 5 which tion 6 and a reduced lower portionl, said lower portion being adapted for external threading. As shown in Fig. 2 of thedrawing, after thestud has been passed through the lopening in the head and the portion 5 rested in the seat 3, aV suitable tool, such as is shown at 8,"is tted about the end of the shank and is `driven upwardly for peeling back the enlarged portion 6 to lie against the undersurface of the head'so` that the stud will be firmly upset inv position on the head. The stud is made of aluminum aswell as is the head so that there will be no' danger of electrolytic action such as mightbe present if different kinds `of metals were employed. By forming-the stud of aluminum, it is, inate rust. 'i 4 The stud is preferably made from heavy wire and is formed in a heading machine by the wellknown upset process. This stud may, of course, like the head, be produced in large quantities at a very cheap figure. The reduced portion 'l of the shank is threaded, as indicated at 9 in Fig. 3 of the drawing and said threaded portion is adapted to receive a securing nut lll which overlies a washer Il, which washer bears against the inner face of the surface to be patched, a portion of such a 4surface being shown at l2 in Fig. 3. It

of course, possible to elim- ,PATENTOFFICE should, of course, be understood that the portion I is passed through the leak, said leak being enlarged to permit such passage, and then the nut I0 is screwed into place, after the washer has been placed in its proper position.

While it has been shown that the head is to be formed of circular frusta-conical shape, it should be understood that if it is desired to mend irregular surfaces, the head of the patch may be bent to conform to the shape of the surface to be mended. .l

Carried by the head I, at its lower surface, is a sealing disk I3 which is formed of cork, soft rub.- ber or any other suitable sealing material. The

sealing disk is of a diameter slightly greater* than the diameter of the head so that itsouter circumferential edge projects beyond the circumferential edge of the head.A The disk I3 is provided with a relatively large central opening I4 which is adapted to receive the inwardly pressed portiondening the seat 3. Itwill be-understood that this inwardly pressed portion cooperates with the opening III for retaining the sealing disk in proper position on the head. After the patch has been placed in position and the nut has been placed on the threaded portion 8,. said nut is tightened for closely and uniformly clamping the sealing disk about the leak to be mended. It will be seen, therefore, that the leak will be effectually sealed so that further leakage therefrom will be an impossibility. i

My improved patch, after being placed in position, will last throughout the remainder of the.

life of the utensil to which it is attached and will, in all probability, require no further attention. Should, however, the device become loose, it is only necessary to tighten on the nut I0, when the patch will again be firmly anchored in place. The flat portion 2 of the head will firmly engagethe outer edge of the sealing disk, without .mutilating said surface, and will effectually retain. the

sealing disk in sealing position throughout the length of the entire circumferential edge of the head. It should be understood that, vwhile I have shown the head and shank of the preferred form of my device as being in two pieces, said head and shank may be formed ,from `a single piece of.


Referring now more particularly to ythe modification of my invention, Aas shown in Fig. -4, I employ a head I5 which is of substantially identical construction with the 4head I. Mounted on the head I5 is a stud I G having an externally threaded shank II and a flattened enlarged upper portion I8 which projects above vthe surface of the head I5. The shank is shownin elevation in Fig. 5 of the drawing and is provided withribs I9 which are upset against the lower surface of the head by a tool similar to the tool shown at!!f so that the head and stud will-be firmly mounted as a unit. VA sealing disk, similar -torthe `disk shown at I3 in the preferred formfis employed with this modified form and a nut is, of course,

screwed upon the lower end of the shank I1. The operation of the device is similar to that of the preferred form but this construction is advantageous inasmuch as cheapness in manufacture is accentuated.

Referring now to the modification of my invention as shownin Figs. 7 and 8 of the drawing, I employ a substantially frusto-conical head I9 having a flat marginal edge 20. The head is formedof the same material as is employed in connectionwith the preferred form of the invention. Formed in the head I9 are radially ex- `v`tending upwardly pressed portions defining ribs 2| which are gradually reduced in height toward the edge of the head so that said head will be retainedagainst undue spreading movement. A stud'22 having an externally threaded shank 23 is carried by the head and is adapted to function in a manner identical with that of the preferred form; This form of the invention will serve the same purpose, and will operate in a manner identical with the preferred form of the invention, aside from theabove-mentione'd ribs, which will, as stated,.prevent rotative'movement of the sealing disk vcarried beneath the head.

lReferring nowto theA modification of the invention as shown in Figure 9 of the drawing, I

employfa head 24 which is provided with an axial socketf25. The socket is adapted to receive the upper end portion 26 of a stud 2I, and as will be observed, the upper surface of the stud is adapted to lie in the same plane with the head 24. It will be seen that a smooth upper surface for the head will be provided.

In- View of the foregoing description, it is thought that the construction and operation of my device ywill be clearly understood. Further description thereof will be unnecessary.

Having. thus described the invention, I claim:

1. A device ofthe character described comprising a concavo-convexed disk having its outer face convexed and its inner fac'e concaved, said disk -beingformed with a center opening and about the opening being depressed to form a countersunk seathaving .a marginal wall and an inwardly extendingannular flange bordering the opening, a stud having a shank extending through the opening and a head at the outer end of the shank snugly received in said seat with its marginal edge face contacting with the marginal wall of the seat, said shank having a thickened portion engaged through the opening and upset to vform a collar engaging the under face of the seat' flange and clamping the flange against the head to firmly unite the disk and stud, and securing means adjustably carried by said stud.

2. The structure of claim 1 and a sealing pad tting'against the'inner face of said disk, said padconforming to the contour of said disk and fitting 'snugly about the marginal wall of the countersunk seat of the disk to prevent movement of the pad radially of the disk. 1
