Application November 17, 1936, Serial No. 111,313 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 gether. At one end, the body portion of the section or Removing sewage and clogged matter from unit 9 is bifurcated and the furcations are~de 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 20 of safe, reliable, and simple uniting means. The precise details relied upon to import struc tural newness and features of re?nement will become more readily apparent from the accom panying 25 drawings and detailed description thereof. . In the drawings wherein like numerals are employed to designate like parts throughout the v1ews:— Figure l is a side or edge elevational view of 30 a sewer cleaning rod assembly or structure em bodying the improved couplings constituting the novelty of the present invention. Fig. 2 is an enlarged close-up elevational view depicting the coupling means with greater par 35 40 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 30 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 ticularity. it can swing into substantially obtuse angular ' Fig. 3 is a top plan view of Fig. 2. Fig. 4 is a sectional and elevational view, the section being taken on the plane of the irregular line 4-4 of Fig. 2. 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 Fig. 5 is a transverse or cross sectional View on the plane of the line 5-5 of Fig. 3. Figs. 6 and 7 are elevational or detail views of the companion units or sections of the improved coupling means. 45 noted by the numerals l3, these being disposed in spaced parallel order and having therebe tween opposed vertical rigid studs or pins I4 and 10 !5 respectively. The body portion of the section _ 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 The ad jacent or proximate ends of the rods are joined 50 sectional form and of suitable length. together by the companion male and female coupling units or members 9 and I0 respectively of the type shown in Figs. 6 and 7. These cou 55 pling units or members are preferably in the 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. 55 , 2,115,194 Minor changes in shape, size, and arrange ment of details coming within the ?eld of. inven tion claimed may be resorted to in actual prac ~tice, if desired. 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 10 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.’ GEORGE BURTON.
