Description
This invention relates to a pipe-coupling for connecting a pipe such as a drain-pipe to a header or for connecting one header to another.
~ 'rench patent Application No 79 11979 (now patent ~o 2,456,280) describes a pipe-coupling for connecting a drain-pipe to a header, in which provision is made for an elbowed connecting-pipe and for a clip which is adapted to fit tightly around the header in order to receive the connecting-pipe, said connecting-pipe being provided with an orifice which is intended to be positioned opposite to a corresponding orifice of the header.
The bottom generator-line of the connecting-pipe is tangent to the top generator-line of the header, with the result that the difference in height between the bottom portion of the connecting-pipe and the top portion of the header is practically zero.
This type of pipe-coupling ofEers the advantages mentioned in the patent cited above. However, it is found that this arrangement cannot prove satisfactory in the particular case in which the fall of water or head available between the streams of water of the pipe and of the header is too small to permit the possibility of connecting said pipe to the upper portion of the header.
It is consequently impossible in such a case to obtain a suita~le connection with the top portion of the header.
The object of the invention is to solve this

This type of pipe-coupling ofEers the advantages mentioned in the patent cited above. However, it is found that this arrangement cannot prove satisfactory in the particular case in which the fall of water or head available between the streams of water of the pipe and of the header is too small to permit the possibility of connecting said pipe to the upper portion of the header.
It is consequently impossible in such a case to obtain a suita~le connection with the top portion of the header.
The object of the invention is to solve this
-2-proble~ by providing a pipe-coupling which can be utilized sati.sfactorily in the case under consideration, that is to say with a head of wa~er or height of fall which is smaller than the diameter of the header while remaining ~3reater than the difference between the radii of the two plpes.
The pipe-coupling contemplated by the invention comprises a member for connecting the pipe to the header, and a clip adapted to fit over the header and to receive the connecting-member.
In accordance with the invention, the clip is inclined laterally with respect to the header and the connecting-member is provided with a truncated end-piece in order to ensure that the cross~section planes of the two ends of said connecting-member form a dihedral angle of less than 90 degrees. This accordingly makes it possible to vary the angle of incidence of the pipe with respect to.the header as a function of the angular position of the clip and of the angular orientation of the connect-ing-member on the clip.
Thus a connection can be established with a low height of fall between the streams of water of the two pipes, this being achieved by increasing the depth of overlap of the incident pipe to a corresponding extent.
This result is obtained by reducing the dihedral angle formed by the cross-section planes of the two ends of the lateral connecting-member to a value which is smaller than 90 degrees.
Under these conditions, the value of the height of fall between the water streams of the pipes to be coupled may vary as a function of the angle of slope given to the clip at the moment of positioning of said clip on the header.
Other features of the invention will be more apparent upon consideration of the following description and accompanying drawings, wherein :
- Fig. l is an exploded view in perspective showing a first embodiment of the pipe-coupling in accordance with the invention ;
- Fig. 2 is a side view in half-section and half-elevation showing the pipe-coupling after the clip has been placed in position on the header and after the connecting-member has been inserted in the clip ;
- Fig. 3 is a view in half-section and half-elevation showing the pipe-coupling and the header, the clip being in the top position on the header ;
Fig. ~ is a view which is similar to Fig. 5 and shows the clip and the connecting-member in the bottom position on the header ;
- Fig. 5 is an axial horizontal sectional view of a second embodiment of the pipe-coupling in accordance with the invention ;
_~ _ - Fig. 6 is a perspective view of the pipe-coupling of Fig. 5 in third-angle projection and showing the interior of the end-piece of said pipe-coupling.
The pipe-coupling illustrated in Figs. 1 to 4 is intended to e~uip drain-pipe systems, especially for agricultural drainage.
Said pipe-coupling comprises a member 1 for connecting a pipe (not illustrated but consisting of a drain-pipe, for example) to a header 4. The coupling further comprises a clip 3 which is adapted to fit tightly around the header 4 and to receive the connecting-member 1.
The clip 3 (of the type described in the French patent cited earlier) has a circular cross-section and is provided with two curved wings 3a having the intended unction of elastically gripping the header 4.
Finally, the clip 3 is provided with an orifice 5 having an outer collar which is adapted to receive the end-piece of the connecting-~ember 1 and with an inner collar 6, the header 4 being provided with an orifice having the same diameter as that of the orifice 5.
In accordance with the invention, the clip 3 is inclined laterally with respect to the header 4 and the connecting-member 1 is provided with a truncated elbowed end-piece 2 which is adapted to fit by latch engagement within the outer collar 10 of the clip 3.
To this end, the collar 10 is provided with internal latch enga(3ement claws (not shown in order not to complicate the drawing unduly) which are similar to tne latch engagement.claws described in the patent c.ited earlier and which are capable of engagement wi~hin a corresponding annular groove 20 of the truncated end-piece 2.
Said end-piece is truncated immediately after the start of the elbow as shown in particular in Fig. 2, with the result that the cross-section planes o~ the two ends of the member 1 form a dihedral angle of less than 90 degrees.
Correlatively, the end-piece 2 is so designed as to obtain a variation in the inlet slope by rotating the lateral connecting~member 1 in the clip 3.
Moreover, as illustrated in Figs. 3 and 4, it is possible to vary the angular position of the clip 3 on the header 4 between a top position (shown in Fig. 3) and a bottom position (shown in Fig. 4). In each possible angular position of the clip 3 or in other words in respect of the different available values of head or height of fall, the connecting-member 1 can be oriented angularly in such a manner as to be inclined at an angle of slope which is compatible with a correct flow.
For example, in Fig. 3, the angular position of the clip 3 is adapted to a height of fall H equal to the difference in diameters of the pipes 1 and 4.
On the other hand, in Fig. 4, the angular position of the clip 3 is suited only to a height of fall h equal to the difference in radii of the pipes 1 and 4, these two values of height of fall being limiting values.
The reduction in height of fall between the streams of water in the two pipes (drain-pipe and header-pipe 4) increases the depth of overlap of the incident pipe to a corresponding extent.
In a second embodiment of the pipe-coupling which is illustrated in Figs. 5 and 6, the drain-pipe (not shown) has a cross-sectional area which is smaller than that of the orifices of tAe clip 3 and of the header-pipe.
The end-piece 11 of the lateral connecting-member 9 is flared-out and has an annular zone 12 which is inclined at an angle ~ with respect to the axis X-X of the member 9.
In consequence, the cross-sectional area of the outlet orifice of the truncated end-piece 11 is sub-stantially larger than the cross-sectional area of the front cylindrical portion 9a of the connecting-member 9.
By way of indication without any limitation being implied, the angle ~ can have a value of the order of 20 to 30 degrees as a function of the difference between these cross-sectional areas.
Thus the truncated end-piece 11 has an internal sloping surface 13 over which the thin incident streams of water flow prior to entry into the header-pipe.
The above-mentioned inclined sloping surface 13 corresponds to an angle of bend of the connecting-pipe which is suf~icientl~ small to prevent any interference with the flow of water streams in the event of slantwise admission. This result is due to optimum utilization of the flared-out portion oDtained by increasing the cross-sectional diameters provided for flow of water between the incident connecting-pipe and the orifice of the clip 3.
In consequence, the use of the pipe-coupling thus provided at the mid-section of the header or in other words in the lowermost position illustrated in Fig. 4 calls for orientation of the connecting-pipe 9 in the direction of flow of the header and ensures that the direction of flow of the incident streams of fluid is closer to the direction of flow of the fluid streams within the header than in the case of an admission of fluid at right angles to the header.
The invention is not limited to the embodiments described in the foregoing and can accordingly extend to alternative forms of construction. Thus the bend angles of the truncated end-pieces 2 and 11 can ~ary within fairly broad limits. Furthermore, it i5 possible to ..
construct a pipe-coupling of this type for the purpose of connecting one header to another, in which case the first header constitutes the incident connecting-pipe.
The pipe-coupling contemplated by the invention comprises a member for connecting the pipe to the header, and a clip adapted to fit over the header and to receive the connecting-member.
In accordance with the invention, the clip is inclined laterally with respect to the header and the connecting-member is provided with a truncated end-piece in order to ensure that the cross~section planes of the two ends of said connecting-member form a dihedral angle of less than 90 degrees. This accordingly makes it possible to vary the angle of incidence of the pipe with respect to.the header as a function of the angular position of the clip and of the angular orientation of the connect-ing-member on the clip.
Thus a connection can be established with a low height of fall between the streams of water of the two pipes, this being achieved by increasing the depth of overlap of the incident pipe to a corresponding extent.
This result is obtained by reducing the dihedral angle formed by the cross-section planes of the two ends of the lateral connecting-member to a value which is smaller than 90 degrees.
Under these conditions, the value of the height of fall between the water streams of the pipes to be coupled may vary as a function of the angle of slope given to the clip at the moment of positioning of said clip on the header.
Other features of the invention will be more apparent upon consideration of the following description and accompanying drawings, wherein :
- Fig. l is an exploded view in perspective showing a first embodiment of the pipe-coupling in accordance with the invention ;
- Fig. 2 is a side view in half-section and half-elevation showing the pipe-coupling after the clip has been placed in position on the header and after the connecting-member has been inserted in the clip ;
- Fig. 3 is a view in half-section and half-elevation showing the pipe-coupling and the header, the clip being in the top position on the header ;
Fig. ~ is a view which is similar to Fig. 5 and shows the clip and the connecting-member in the bottom position on the header ;
- Fig. 5 is an axial horizontal sectional view of a second embodiment of the pipe-coupling in accordance with the invention ;
_~ _ - Fig. 6 is a perspective view of the pipe-coupling of Fig. 5 in third-angle projection and showing the interior of the end-piece of said pipe-coupling.
The pipe-coupling illustrated in Figs. 1 to 4 is intended to e~uip drain-pipe systems, especially for agricultural drainage.
Said pipe-coupling comprises a member 1 for connecting a pipe (not illustrated but consisting of a drain-pipe, for example) to a header 4. The coupling further comprises a clip 3 which is adapted to fit tightly around the header 4 and to receive the connecting-member 1.
The clip 3 (of the type described in the French patent cited earlier) has a circular cross-section and is provided with two curved wings 3a having the intended unction of elastically gripping the header 4.
Finally, the clip 3 is provided with an orifice 5 having an outer collar which is adapted to receive the end-piece of the connecting-~ember 1 and with an inner collar 6, the header 4 being provided with an orifice having the same diameter as that of the orifice 5.
In accordance with the invention, the clip 3 is inclined laterally with respect to the header 4 and the connecting-member 1 is provided with a truncated elbowed end-piece 2 which is adapted to fit by latch engagement within the outer collar 10 of the clip 3.
To this end, the collar 10 is provided with internal latch enga(3ement claws (not shown in order not to complicate the drawing unduly) which are similar to tne latch engagement.claws described in the patent c.ited earlier and which are capable of engagement wi~hin a corresponding annular groove 20 of the truncated end-piece 2.
Said end-piece is truncated immediately after the start of the elbow as shown in particular in Fig. 2, with the result that the cross-section planes o~ the two ends of the member 1 form a dihedral angle of less than 90 degrees.
Correlatively, the end-piece 2 is so designed as to obtain a variation in the inlet slope by rotating the lateral connecting~member 1 in the clip 3.
Moreover, as illustrated in Figs. 3 and 4, it is possible to vary the angular position of the clip 3 on the header 4 between a top position (shown in Fig. 3) and a bottom position (shown in Fig. 4). In each possible angular position of the clip 3 or in other words in respect of the different available values of head or height of fall, the connecting-member 1 can be oriented angularly in such a manner as to be inclined at an angle of slope which is compatible with a correct flow.
For example, in Fig. 3, the angular position of the clip 3 is adapted to a height of fall H equal to the difference in diameters of the pipes 1 and 4.
On the other hand, in Fig. 4, the angular position of the clip 3 is suited only to a height of fall h equal to the difference in radii of the pipes 1 and 4, these two values of height of fall being limiting values.
The reduction in height of fall between the streams of water in the two pipes (drain-pipe and header-pipe 4) increases the depth of overlap of the incident pipe to a corresponding extent.
In a second embodiment of the pipe-coupling which is illustrated in Figs. 5 and 6, the drain-pipe (not shown) has a cross-sectional area which is smaller than that of the orifices of tAe clip 3 and of the header-pipe.
The end-piece 11 of the lateral connecting-member 9 is flared-out and has an annular zone 12 which is inclined at an angle ~ with respect to the axis X-X of the member 9.
In consequence, the cross-sectional area of the outlet orifice of the truncated end-piece 11 is sub-stantially larger than the cross-sectional area of the front cylindrical portion 9a of the connecting-member 9.
By way of indication without any limitation being implied, the angle ~ can have a value of the order of 20 to 30 degrees as a function of the difference between these cross-sectional areas.
Thus the truncated end-piece 11 has an internal sloping surface 13 over which the thin incident streams of water flow prior to entry into the header-pipe.
The above-mentioned inclined sloping surface 13 corresponds to an angle of bend of the connecting-pipe which is suf~icientl~ small to prevent any interference with the flow of water streams in the event of slantwise admission. This result is due to optimum utilization of the flared-out portion oDtained by increasing the cross-sectional diameters provided for flow of water between the incident connecting-pipe and the orifice of the clip 3.
In consequence, the use of the pipe-coupling thus provided at the mid-section of the header or in other words in the lowermost position illustrated in Fig. 4 calls for orientation of the connecting-pipe 9 in the direction of flow of the header and ensures that the direction of flow of the incident streams of fluid is closer to the direction of flow of the fluid streams within the header than in the case of an admission of fluid at right angles to the header.
The invention is not limited to the embodiments described in the foregoing and can accordingly extend to alternative forms of construction. Thus the bend angles of the truncated end-pieces 2 and 11 can ~ary within fairly broad limits. Furthermore, it i5 possible to ..
construct a pipe-coupling of this type for the purpose of connecting one header to another, in which case the first header constitutes the incident connecting-pipe.
