2. claims. (ol. 13a- 99) My invention relates to an improved emergency leak seal for pipe fittings and pipes.
The subject matter relating to the sealing compound is being embodied in a copending app lication, Serial No. 112,164, filed August v11.
A purpose of my invention is to employ a mixture of fish oil and rosin as a pipe sealing composition, desirably suitably lbacked up by a resilient cushion such as rubber.
A further purpose is to force a rubber or similar resilient cushion into the space at which a pipe fitting joins a pipe, forcing a sealing compound desirably consisting of a mixture of fish oil and rosin into the space to seal leaks.
A further purpose is to apply pressure at a sired point against a resilient pipe sealing cushion by pressure fingers on a pressure clamp.
Further purposes appear in the specifications and in the claims.

Figure 2 shows the same pipe in perspective with the cushion material land clamp in process of application.

Figure 16 is an elevation showing my clamp applied in one manner to an elbow.
Figure 1'? illustrates a slightly variant form of clamp.
l 2 In the drawings like numerals refer" to Vlike parts. f l
Describing in illustration but not in limitation and referring to the drawings: l f
It has been found that pipe leaks, especially in water pipes are very prevalent at the points at whichttings join the pipe sections. For ex'- ample, a very common leak location as shown in Figure 1 is the point 25 where pipe section 26 is threaded into fitting 21. This is an extremely diincult point at which to stop a leak using'conL ventional types of patching devices.
In accordance with my invention I use ani proved leak sealing compound 28 desirably consisting of equal proportions of sh oil such' as sardine, menhaden, cod, berbetV oiland rosin, suitably heated together until the mass is horno` geneous. L
The fish oil and rosin is mixed together preferably in equal proportions, but permissibly with one in greater proportion than the other. j
The mixture is cooked about an hour or'until the ingredients are sufficiently dissolved.
In order to force the sealing compound 28 'into the recesses of the contour adjacent the leak, I apply a cushion material 29, suitably of rubber or synthetic rubber tape, similar or identical with the common rubber electrical' Wiremans tape. The sealing compound may desirably be applied at one edge along the tape, as shown in Figure 3, and the tape wrapped around the pipe against the location of the leak as shown at 30 in Figure 2. or sealing compound may be used over the entire tape.
My preferred clamp is of resilient material such as sheet metal as best seen in Figures 2 and 4. It consists of a collar portion 3|, pressure fingers 32, and rear skirt 33, clamp extensions 34 and a suitable threaded tightening means 35. The clamp suitably loosened will be slipped over the pipe to the location of the leak as shown in Figure 5, being careful that the pressure fingers 32 bear upon the cushion material 29 and do not dig in beyond it at 36.
The clamp is then tightened, reaching a condition as shown in Figure 6, forcing the sealing material and the cushion at 31 into any imperfections or irregularity of the pipe or tting adjoining the leak and sealing off the leak. In some cases, it is desirable to use a specially formed cushion material as shown in Figure 7, where the cushion has sealing material 29' coated on one side of the body portion 39 and also on the bottom of the flange portions 39. When wrapped around the location of the leak. as shown in Figure 9, with the sealing material forcing the other into recesses 'in the 'contour 'of the pipe.
In some cases it is desirable to have an annular pressure ridge on the clamp, as shown at 42 in the modication of Figure 10. This pressure ridge, when used with the cushion material is pressed iirmly in against the ,pipe 'andseals l" against the pipe fitting.
In some cases, the pipe 't'ting of ALFigure v8 'is advantageously used with a sheet of cushionmaf =terial extending over th'e end of the fitting as Shown at 43.in -Figure 1`1.` This cushionmaterial vsll be coated with sealing compound 18' onits inner edge and Wound -or extended up 4over 'the end'o the itting, so that with Ytightening 'of 'the clamp the flaring pt'ionH-I will fforcelthe i'cshionmaterial against the end `o'f the 'fitting 'and 'make a thorough seal at"44.
` In the casev o'fal which vis leaking arondlso'rie point Vof t'he bodr of 'the vit is desirable to e'rn- :p'lay at/saddle 'clam-p15 ha'ving a body ne and vclamp extensions 41 provided with openings #s which receive clamping ineinbei's l9jlocling on either side of th'e baise o'fft'h'e T.

Having thus described my invention What I claim as new and desire to secure by Letters Patent is:
1.
