receives the ring 20. It is further pointed
out that the ring will have such an ample
bearing in the groove and also in the seat
19 as to render accidental displacement sub-
5 stantially impossible. In fact the ring will
seat with such tenacity that a tool will be
required to remove said ring 20 before the
cap can be disengaged from the terminal
post. It will be seen that when it is desired
10 to remove the cap it is merely necessary to
pry the ring loose, and remove it from the
post 12. If the ring 20 is injured in remov-
ing it may be easily replaced by a new one.
It is believed that the invention which has
15 been described will to a large extent elimi-
nate broken cell caps and will certainly
make for cheaper repairs.
It is pointed out that both rings may be
made of rubber or similar elastic material
20 and when so made are interchangeable.
This makes for economy and quick assem-
bly. However it is not my intention to limit
the invention to the 'use of a rubber ring
and this has particularly to do with the fas-
25 tening ring 20.
What I claim, is:
1. In a battery' terminal fastening, the
combination with a cell cap having an open-
ing formed therethrough, said cell cap being
30 provided upon its lower side with a tapered
seat increasing in diameter downwardly, a
terminal post extending through said open-
ing and provided, near the upper surface
of the cap with an annular groove which.is
35 curved in. cross section, a stop element car-
ried by the lower end of the terminal post
and projecting laterally beyond the same
and adapted to be arranged beneath the cell
cap in proximity to the tapered seat, a
40 highly elastic and circumferentially expan-
sible and contractible ring carried by the
lower end of the terminal post and arranged
between the stop element and the tapered
seat, and a second highly elastic and circum-
45 ferentially, contractible and expansible ring
adapted for insertion within said groove and
to contact with the upper portion of said
cap; the last named ring tending to move
downwardly with relation to the cap when
50 contracting within the annular groove.2. In a battery terminal fastening., the
combination with a cell cap having an open-
ing formed therethrough, said cell cap being
provided upon its upper face with a tapered
seat decreasing in diameter downwardly and 55
surrounding said opening, said cell cap, be-
ing provided upon its lower side with a
tapered seat increasing in diameter down-
wardly and surrounding said opening, a ter-
minal post extending through said opening 60
and provided near the upper surface of the
cap with an annular groove increasing in
depth inwardly and having an outwardly
extending flange above the groove, a stop
element carried by the lower end of the ter- 65
minal post and projecting laterally beyond
the same and adapted to be arranged be-
neath the cell cap in proximity to the lower
tapered seat, a highly resilient and circum-
ferentially expansible and contractible.ring 70
carried. by the lower end of the ,terminal
post and arranged between the stop element
and lower tapered seat, arnd a second highly
resilient and circumferentially contractible
and expansible ring arranged within said 75
groove between the flange and upper seat,
the last named ring tending to move down-
wardly with relation to the cap when con-
tracting within said groove.
3. In a battery terminal fastening, the 80
combination with a cell cap having an open-
ing formed therethrough, of a terminal post
extending through said opening and pro-
vided near the upper surface of the cap
with an annular groove increasing in depth 85
inwardly, a resilient and circumferentially
expansible and contractible ring inserted
within the annular groove and engaging.the
upper portion of the cap, said ring tending
to move downwardly with, relation to the 90
cap when contracting in its groove, a stop
element secured to the lower' end of the
terminal post, and a resilient circumferen-
tially expansible and contractible ring sur-
rounding the lower end of the post and 95
confined between the stop element and lower
portion of the cap.
In testimony whereof I affix my signature.
