COUPLING MEMBER FOR CONDUIT RODS, PUMP RODS, ETC
Filed March 5, 1930 w Z5 Z2 Z4 FIE 5 M ,4? 7 Z2 Z4 Zutzm/ w aw/LU M W MM Patented June 2, 1931 UNITED STATES PATENT OFFICE FREDERICK W. FUCHS, OF MILWAUKEE, WISCONSIN, ASSIG-NOR TO TURBINE SEWER MACHINE COMPANY, 013 MILWAUKEE, WISCONSIN, A CORPORATION OF WISCONSIN COUPLING-MEMBER FOR CONDUIT RODS, PUMP RODS, ETC.
Application filed March 3,
This invention relates to improvements in coupling members for conduit rods, pump rods, etc.
The object of this invention is to provide means whereby such'rods may be formed in short sections which are adapted to be hingedly coupled or uncoupled at the top of a manhole and fed vertically to the conduit through the manhole and thence along the conduit to the next manhole without buckling or unhooking in the conduit.
In general, the object is to provide a coupling which will permit the rod sections to be fed into a sewer or conduit with substantially the same facility that a chain might be similarly manipulated but which may be pushed lengthwise of the conduit with the same facility that a continuous rod of equal length could be pushed horizontally through a tube.
More particularly stated, it is my object to provide coupling members which require the rod sections to be adjusted at an acute angle to each other to initiate their connection and which, after such a connection has been initiated, may be swung toward a position of alignment and mutually guided into an abutting non-buckling relation to each other wherein motion may be transmitted lineally without permitting material movement of the parts upon each other under push and pull operations. The rod sections when completely coupled, are in one way hinge joint connection with each other wlth abutting surfaces obliquely placed and tending to normally resist flexion in the only direction in'which the joint can be flexed.
In the drawings:
Figure 1 is a fragmentary'view of two conduit rod sections e uipped with my improved mutually interloc ing coupling members showing the same as they appear when detached.
Figure 2 is a view of the same as they appear when initiating a coupling operation, with dotted lines indicating an intermediate position occupied by one of the sections while eing swung to full coupling position.
Figure 3 illustrates the sections as they ap- 50 pear when fully coupled.
1930. Serial No. 432,604.
Like parts are identified by the same refi erence characters throughout the several vlews.
The rod section 10 has one end'prov ided with a cap 12 having flanges 13 which embrace the end portion of the rod to which iliey are secured by a connecting pin or rivet On the opposite side of the cap 12 from that occupied by the flanges 13 it is provided with a'pair of fork arms 15 intermediately connected by an obliquely flattened hinge pin 17 the preferable cross sectional contour of which is clearly indicated by dotted lines in Figure 3. The hinge pin 17 is located substantially midway between the cap 12 and the extremities of the fork arms 15 and these extremities are provided with inwardly projecting studs 18. The gap between these studs is substantially equal in width to the thickness of the web portion 20 of the coupling member now to be described.
The companion coupling member comprises a cap 21 similar to the cap 12 and having flanges 22 similarly secured to the rod section 23 by a cross pin or rivet 24. The web 20' projects from the opposite side of the cap 21 from that occupied by the flanges 22 and is provided with a head piece 25 at the outer end of the web 20.
One margin of the web 20 is provided with a bearing socket 26 into which the hinge pin or cross piece 17 may be received. The'recess extends inwardly from the margin of the Web with an oblique pitch in the direction of the cap 21 and the inner face or bottom of the recess is rounded in general correspondence to the rounded surface of the hinge pin 17 Between the bearing socket 26 and the ca plate 21, the socketed margin of the web 20 is thickened to provide what maybe conveniently termed a shoulder 28 from which curved finger-like guiding abutments or flanges 29 extend along the base of the bearing socket 26 to guide the studs 18 into coupling engagement as hereinafter explained. Between these flanges 29 and the cap plate 21, the shoulder 28 is provided, on each side of the web, with a socket 30 to receive the studs 18 when the latter are in coupling position.
The outer side of the head piece 25 has an oblique bearing face 83, and at its inner side, on each side of the web 20, it is provided with a rounded recess 3st to initially receive the studs 18 when the members are being assembled. I
At the side opposite the bearing socket 26, the outer end portion of the web 20 is preferably widened or provided with a triangular flange which supports an offset portion of the head piece at this side of the coupling. This portion of the head piece is adapted to abut an oppositely disposed similarly supported stop 3? connected with the cap 12' The face of the cap 12, between the fork arms 15, is obliquely disposed to receive the oblique face 38 of the head piece 25, and the offset portions 36 and 3! will not only resist fleXion of the coupling on that side, but the oblique position of said faces tend to prevent fiexion in the opposite direction.
To couple the sections together, it is first necessary to adj nst them at an acute angle to each other, with the studs 18 embracing the web 20 partially within the head sockets 34c. Thereupon, the section 10 may be swung upon the hinge pin 17 as ind'cated by dotted lines in Figure 2 to cause the studs 18 to travel along the web 20 and be guided by the finger flanges 29 to the sockets 30. In the meantime the head piece 25 will have a relative movement between the fork arms 15 until the nose it) enters the space between the hinge pin 17 and the cap plate 12, where upon the oblique face of the cap piece and the face 3 3 of the head piece 25 will be brought into contact, thus completing the coupling.
\Vhen the coupling has thus been completed, the parts cannot be uncoupled while in a conduit of such din'iensions as to prevent them from being swung relatively to the acute angle at which they appear in Figure 2. By having the studs 18 so located that they bear upon the guiding surfaces of the shoul' der piece 28 when the face 33 of the head piece is in abutting contact with the opposing surface of the cap 12, lost motion, or relative movement of the parts upon each other during the axial movements of the push rod may be prevented.
