Application July 26, 1944, Serial No. 546,701
2 Claims. (Cl. 217-95)
My invention relates to an improvement in
lugs for silos and tanks. These lugs are em
ployed for the purpose of tying together the ends
of the rods or bands which extend around the
silos and tanks.
It is my purpose in developing the present in
vention to provide a lug for the purpose men
tioned which can be a satisfactory substitute
for the cast lugs heretofore commonly used and
yet can be conveniently die-stamped from small
pieces of scrap so as to effect substantial sav

of the channel element l a substantially flat
member is formed by stamping and is bent into
the channel as seen in Figure 3 at 3. These
members 3 incline away from each other slightly
as indicated in Figure 4. The outer faces of the
members 3 ‘are ilush with the edges of the chan
nel element l at the ends of that element so
that the end members hereinafter mentioned

members 3 and against the ends of the channel

It is also particularly my purpose to provide

arranged that while they can be stamped from 15 end of the channel element l and against the
channel member 3 as illustrated for instance in
scraps of sheets, the finished product wil1 have

the sturdy strength and wearing qualities nec
essary for holding the bands or rods on silos,
tanks and other similar structures.
With these and other objects in View, my in
vention consists in the construction, arrangement
and combination of the various parts of my silo
and tank lug wherebyT the objects contemplated
are attained, as hereinafter more fully set forth,
pointed out in my claims and illustrated in the
accompanying drawing, wherein:
Figure 1 is a perspective view of a silo and tank
lug embodying my invention;
Figure 2 is a horizontal sectional View of a por

improved lugs;

the parts of the lug before they are fastened
Figure 4 is a detail sectional view taken on
the line 4--4 of Figure 1, and
Figure 5 is a detail sectional view taken on the
line 5_5 of Figure 1.
In building silos and tanks, it is a common
practice to put iron rods, sometimes called
“bands,” around the structure. The ends of
each band must be fastened together, and to ac
complish this purpose of fastening them together,
it is the common practice to use so-called lugs.
Cast lugs have been used for many years. By
some they have been considered the best for the
purpose because they had the inherent strength
and sturdiness necessary for the purpose. Some

to the members 3. Each end member 4 has a
substantially right angle flange 6 along one edge
and the parts are so arranged that when the end
member is in position, the ends of its flange 0
seat snugly in the notches 2 at that end of the
lug. 'I‘he ñanges 6 serve the purpose of reinforc
ing and strengthening the lug. They also afford
a relatively broad fiat surface that will not cut
into the face of the silo or tank wall as the edges
of the channel-shaped element l at the sides
thereof might do in some cases.
In using my improved lug, it is installed in the
same Way as is any other lug.
In Figure 2, 'l shows the silo wal1 and 8 is the
band, the ends of which are extended through
the holes in the lug and receive nuts 9.
Lugs of the kind under consideration can be
stamped from scrap pieces of sheets. The dies
used in making the stamping are comparatively
simple and the number of operations for com
pleting keach lug is small. I have found that the
lugs are strong enough to stand up under all
ordinary conditions of use.
It is my purpose to cover by my claims any such
departures from the exact structure illustrated
in the drawing that may come within the scope
of my invention and of such claims.
I claim as my invention:
