Abstract
A plastics member 2 having a C-shaped part 3 is to be welded to a plastics pipe 4 whilst clamped to it by a clamping device 1. A part 9 of the device 1 is pressed by a spring 10 into a pocket 3a in the part 3 and towards a part 12 to which a clamping band 6 is fixed. A connecting member 14 is fixed to the band 6 and projects into a pocket 3b in the part 3. The spring pressure, controlled by a spindle 7, causes the part 3 to be pressed against the pipe around a portion of the periphery of the latter and the band 6 to be pressed against the pipe around a substantial portion of the periphery of the latter. <IMAGE>
Description
SPECIFICATION
A device for clamping a plastics member to a plastics
pipe whilst they are welded together
Forthe welding to pipes, made of plastics material, of
"Anborschellen" (possibly boring pipe boxes,
centering clamping rings or centering collars) which
are also made of plastics material and which almost
completely surround the pipe, a clamping device is
known (Georg FischerA.G.'s Catalogue No. Fl 1169/1,2,4/8.83), comprising two parts both of which
act directly on the memberto be welded to the pipe.
This clamping device is notsuitableforplastics members which have a so-called "saddle" (the part
which is pressed against the pipe) which extends
much less than all theway,forexample less than
three quarters of the way, around the periphery ofthe
pipe.
According to a first aspect of the invention, there is
provided a clamping device which is suitable for
clamping a member made of plastics material to a
pipe made of plastics material whilst said member
and pipe are being welded together, the clamping
device including a first part for acting on one part of said member, a second part which has partofa clamping band connected to it, connecting means for
connecting another part of the clamping band to another part ofsaid member and urging means for
urging one of the first and second parts to move with
respect to the other, with the result, if said member
has an appropriate shape and size and the pipe has
an appropriate diameter, that the clamping band is
tensioned and directly contacts and presses against
the pipe around a substantial portion of its periphery
and said member presses againstthe pipe around
another substantial portion of its periphery.
In orderthatthe clamping device may be used with
pipes of differing diameters, more particularly with a
number of differing standard pipes, and with
differing members to be welded to similar or
differing pipes (a) there may be another clamping
band which can be incorporated in the device in
place ofthefirst-mentioned clamping band to
provide a greater or lesser length of band between
said second part and said connecting means or (b)
there may be a plurality of connecting means spaced
apart along the band and the appropriate connecting
means, according to the shape and dimensions of the plastics member and the diameter of the pipe,
can then be selected for use, the other or others not
being used or (c) the length of band between said
second part thereof and said connecting means may
be adjustable.
According to a second aspect of the invention,
there is provided an assembly of a pipe made of
plastics material, a member made of plastics
material which is to be welded to the pipe and a
clamping device according to the first aspect of the
invention, the band being tensioned and in direct
contactwith and pressing againstthe pipe around a
substantial portion of its periphery and said member
being pressed against the pipe around another
substantial portion of its periphery.
Examples in accordance with the invention are described below with reference to the accompanying drawings in which:
Figure 1 shows plasticsmemberclampedtoa plastics pipe by a clamping device, and
Figure2 shows a different plastics member clamped by identical clamping device to a plastics pipe of lesser diameter.
Figures 1 and 2 show pipes 4 and 4a to which members 2 and 2a, respectively, are to be welded, all these parts being made of plastics material and the parts 4a and 2a being smallerthanthe parts 4 and 2.
Forthewelding operation the members 2 and 2a are clamped to the pipe by identical clamping devices 1.
The members 2 and 2a include so-called "saddles" 3 which are substantially C-shaped, the inner diameters of the saddles being approximatelythe same as the external diameters of the pipes to which they are welded. The saddles are to make contact with the pipes and be pressed against them around more than half but less than three-quarters of the peripheries ofthe pipes. The two ends of the C in each case extend outwardly and backwardly to provide pockets 3a and 3b in the form of grooves which extend along the length (perpendiculartothe plane of the paper) ofthesaddle.
The clamping device consists of a first part 9 which acts directly on one end of the saddle by projecting into the pocket 3a and pushing on the end ofthe C and urging it towards a second part 12which is a connection for one end of a clamping band 6. The part 12 is at the lower end of an arm 13 in which is a slot into which projects a portion of the part 9 so that the part9 can travel up and down the arm 13, guided by the slot. An internally screw-threaded part 11 is fixed to the upper end ofthe arm 13 and into it is screwed a screw-threaded spindle 7 which has an operating knob 8 at one end and engages at its other end one end of a compression spring 10 which exerts a force, adjustable by turning the spindle 7, on the part 9 and thus on the near end of the saddle. There could be two or more springs and spindles, spaced apart along the saddle.The assembly of parts 7 to 13 is designated Sin the drawing.
One end of the band 6 is formed with an eyelet which co-operates with the part 12 to secure the band to the assembly 5 and a similar eyelet is formed atthe other end of the band. There a re also th ree more eyelets attached to the band, each of them holding a hoop-like connecting member 14, 14a or 14b one of which, according to the dimensions of the pipe and the saddle, can be swung upwardly to project into the pocket3b. In Figure lit is the connecting member 14 and in Figure2 it is the connecting member14b which is effective in this way, the others not being used.Upon turning ofthe spindle orspindles 7the parts 9 and 12 ofthe clamping device areforced closertogetherbythespring or springs 10 and the band 6 is tensioned and directly contacts and presses againstthe pipe around most of that part ofthe periphery of the pipe which is not in contact with and pressed against by the saddle.
The line of application 15 of the force exerted on the part9 by the spring or springs 10 passes through the centre ofthe connection between the part 12 and the band and is substantially parallel to a plane which istangentialto the pipe atthe partofthe pipe nearest the part 12, being spaced from that plane by the radius ofthe eyelet engaging the part 12. Both ends ofthe C are acted upon bysubstantiallytangential forces.
One band 6 as illustrated in Figures 1 and 2 may be used for one particular member 2 and pipes with diameters of 63, 90 and 125 mm. and another and longer band 6 may be used forthe same member2 and pipes with diameters of 180,250 and 315 mm..
Alternatively,forthese pipe sizes there may be six differing bands 6, each with the appropriate length and with the connecting member 14 but notthe connecting members 14a and 14b.
