2 Claims. (Cl. 13S-9S)
This invention relates to an improved mend

vide a device of this character embodying a seal
ing disc of soft material which, when the patch Normally seated beneath the head l and within
the conñnes of the flange 2, '
is tightened to locked position, will be fully en
closed by a depending flange on the head of the washer t which is formed of
device so that said sealing disc will be eiîectually suitable soft material.
Another object of the invention is to provide
a mending patch wherein the head is formed
with a depending flange so that reinforcement for
the circumferential edg-e will be provided.
A further object of the invention is to provide
patch wherein the iiange employed will
prevent bending up >of the head with consequent
mutilation of the sealing disc.

as shown in Figure 6, we employ a head which is
indicated inrgeneral by the numeral 25. The head
is provided with an upwardly pressed semi-cir

upper and lower portions 45 and 46, and also a
stud 2l which is adapted to project through a
surface or wall to be patched. A nut 28 is pro
vided on the stud, as is a washer 2S which washer
is adapted to underlie the wall, as shown at Sil,
30 and thus provide a firm base against which to
tighten the nut 28. Formed on the circumferen
tial edgeof the head 25 is a depending flange 3l
which terminates in a radial flange 32, which,
like the radial flange 23, is adapted. to overlie the

the puncture in the wall or surface. The rib 2t
provides reinforcement for the head and also
serves as a guard, so that when the article to
which the patch is secured is being cleaned, the
cleaning cloth or scraper will not be permitted to
catch under the upper end of the stud 2l. Inas
much as the portion 45 is of greater height than
the portion d6, a greater pressure will be exerted
45 on the depending iiange 3l and radial flange 32.
Aside from this feature, the constructionV and op
eration of this modified form of the invention is
identical with that disclosed in the modiiication
shown in Figure 4.
In the modiñcation shown in Figure 7 of the
drawing, we employ a substantially frusto conical
head 34 which «is provided with a depending
flange 35 and a radial flange 35 corresponding to
the flanges 3l and 32 in Figure 6. The head is
provided with a stud 31 which is provided with an
enlarged upper portion or cap 33 carried in a
recess 39 formed in the head 3A. The stud is
adapted to project through the surface or wall to
