1 Claim. (Cl. 287-103)
This invention relates to that classi?cation of form of aluminum castings. Each casting in
structures now generally identi?ed as sewer clean
cludes what may be called a channel-shaped por
ing rods and has reference in particular to a tion l l and the rods are located therein between
speci?cally new type coupling for pivotally and the side ?anges and secured in place by bolts or
separably connecting the companion rods to
equivalent fasteners as indicated at I2 in Fig. 5. 5
At one end, the body portion of the section or

sewerage systems through the instrumentality of
disconnectable pivotally jointed rod devices, is
now common practice. Generally speaking the
device is made up of a plurality of wooden sticks
of appropriate shape and length, these being sep
arably coupled together at coordinated ends.
The purpose of the present invention, as above
15 implied, is to provide a new type coupling be
tween the wooden sticks or rods, the coupling
being made up of complemental male and female
members or sections, and these being separably
and pivotally joined through the instrumentality

The precise details relied upon to import struc
tural newness and features of re?nement will
become more readily apparent from the accom
and detailed description

employed to designate like parts throughout the

it is in the nature of a shank shaped and propor
tioned to ?t between the furcations. The shank
may be said to be of general rectangular cross
sectional form and it is denoted by the numeral 15
[6. In one longitudinal edge is a substantially
diagonal notch ll terminating in a rounded crotch
portion forming a seat l8 for the pin I4. On this
same side is an appropriately shaped retention
hook l9 engageable with the pin. On the op- 20
posite side, the extension or shank I6 is formed
with a substantially V-shaped notch 20 to re
ceive the retention pin [5. This notch formation
in effect de?nes an abutment or guard ?nger as
at 2|, which is. enagageable also with said pin l5.
Thus, by slipping the shank H5 in between the
furcations l3 and engaging the hook IS with the
pin Ill, this locates the pin [5 in the V-shaped
notch 20, and places the ?nger 2| in a position to
insure an appropriate quick releasable connec
tion between the parts 9 and In.
With this type of a coupling it is evident that
the rod 8 can pivot in one direction‘ only, that is
it can swing into substantially obtuse angular '

tion of the lug 2| with the pin l5 prevents angling
of the rod in the opposite direction, that is, in
a horizontal plane. Incidentally the word “hori-.
zontal” is used advisedly, having reference only
to the drawings, and particularly Figs. 1, 2 and 4. 40

Referring now to the drawings by distinguish
ing reference numerals, it will be observed that
the wooden sticks or rods are denoted by the num
erals 8 and these are more or less conventional in
design. They are generally rectangular in cross

coupling units or members 9 and I0 respectively
of the type shown in Figs. 6 and 7. These cou

relationship in one direction only. The associa- 35
That is to say, since the device is usable in both
horizontal and vertical directions, it is obvious
that the description relates to the drawings only.
A coupling of the type speci?cally described
and illustrated is believed to be competent and 45
reliable for the duties to be performed. It pos
sesses requisite stability and is otherwise propor
tionately'ef?cient to aptly measure up to the re
quirements of an assemblage of this type.
It is thought that persons skilled in the art 50
to which the invention relates will be able to ob
tain a clear‘understanding of the invention after
considering the description in connection with
the drawings. Therefore, a more lengthly de
scription is regarded as unnecessary.

Minor changes in shape, size, and arrange

What is claimed'as new is:¥
' A'sewer plunging and dislodging device com
' prising a pair of complemental rods, coupling
means separably joining adjacent ends of said
rods and comprising maleand female coupling
units, one unit embodying spaced parallel furca-V
tions forming'a slot therebetween and having a
_ pair of transverse connecting pins extending
therebetween equidistantly spacedv from the in- ‘
ner end of the slot, the other unit comprising a.
- shank for location in said slot, said shank com'‘—‘
prising a hook extending between the pins to
take over one pin whereby said units are inter
locked against endwise separative movement out
wardly of each other and swingable relatively in
to angular relation, and a ?nger adapted to bear
against the outer side of the other pin to stabilize
the hook, said ?nger cooperating with the inner '
end of the slot to block relative swinging of said
sections in one direction and being swingable 10
around said other pin during swinging movement
of the interlocked units in the other direction.’
