Abstract
A drain rod in which the male connector is formed from a tubular part 11 machined from tube stock and a spigot part 13 machined from bar stock. The tubular part has an internally threaded portion to receive the threaded spigot part, a portion of which is unthreaded to prevent it unscrewing from the tubular part. The rod member 10 abuts against the spigot part to prevent it screwing into the tubular part. <IMAGE>
Description
SPECIFICATION
Cleaning devices
This invention relates to drain rods of the kind comprising a rod of flexible material such for example as polypropylene and male and female connector members at its opposite ends respectively whereby a number of rods can be connected together in end to end relationship.
The connector members are formed from brass and it has long been the practice to form the members as hot brass pressings and to subject them to machining operations to produce, in the case of the female connector member, an internal screw thread and in the case of the male connector member, a threaded spigot.
The production of hot brass pressings requires specialised knowledge and expensive equipment and in itself is not a clean process. The resultant pressing however is economical in that very little material has to be removed from the pressing to produce the connector member. If an attempt is made to machine the members from stock material then whilst the female connector member can be produced from tube stock with little scrap, the production of the male connector member from solid stock involves a good deal of scrap.
It is therefore an object of the invention to provide a male connector member for a drain rod in a simple and convenient form.
According to the invention a male connector member for a drain rod comprises a tubular part one end portion of which is provided on its internal surface with a screw thread, the remaining portion of the internal surface being of a size to receive the rod of flexible material, and a spigot part having an external thread part of which is engaged with the threaded end portion of the tubular part, said spigot part extending out of said tubular part for engagement in use with the female connector member of an adjacent rod and means acting to retain said parts against relative angular movement.
The male connector member may be produced by conventional machining processes from tube and bar stock on an automatic lathe. This reduces the amount of labour and expensive plant required as compared with the production of the known connector members as hot brass pressings.
In the accompanying drawings: Figure 1 is a sectional side elevation through one end of a drain rod showing the male connector member,
Figure 2 is a sectional side elevation of one part of the male connector member,
Figure 3 is a side view of the other part of the male connector member, and
Figure 4 is a view similar to Figure 1 showing the female connector member.
Referring to Figure 1 there is shown one end of a drain rod including a rod member 10 formed from flexible material for example, polypropylene.
The end of the rod is a close fit within a tubular part 11 of the male connector member which is generally indicated at 12. The outer end portion of the part 11 is provided with an internal screw thread and engaged with the thread is the spigot part 13 which forms the other part of the connector member.The spigot part is of solid cylindrical form and is provided with a screw thread for engagement with the screw thread in the part 11. The inner end portion 14 of the part 13 is of plain cylindrical form and the two parts are engaged with each other by placing the part 13 within the part 11 and "unscrewing" the part 13 out of the part 11. The inner end portion 14 on the part 1 3 since it is not threaded, prevents the part being unscrewed completely and the end of the rod 10 which abuts the part 13 and which is secured firmly by a pin (not shown) or other retention arrangement, in the part 11, prevents the part 13 turning relative to the part 11 in the opposite direction. In order to provide a rigid connection the threads on the spigot part may taper inwardly from the end portion 14.The projecting portion of the part 13 is engaged in use, with the female connector of the adjacent rod.
The two parts 11 and 13 are produced by simple machining operations from tube and bar stock respectively on for example, an automatic lathe, and by careful choice of the sizes of the two types of stock, only a small amount of material needs to be removed.
The female connector as shown at 1 5 in
Figure 4, is produced in the same manner as the part 11 and from the same size of tube stock. It will be noted that the threaded portion of the female connector is slightly longer than the threaded portion of the part 11 of the male connector. This is to assure a positive connection with the male connector of the adjacent rod when the rod is in use.
1. A male connector member for a drain rod comprising a tubular part one end portion of which is provided on its internal surface with a screw thread, the remaining portion of the internal surface being of a size to receive the rod of flexible material, and a spigot part having an external thread part of which is engaged with the threaded end portion of the tubular part, said spigot part extending out of said tubular part for engagement in use with the female connector member of an adjacent rod and means acting to retain said parts against relative angular movement.
2. A connector member according to claim 1 in which the spigot part of the connector is provided with an unthreaded portion at its end within the tubular part thereby to prevent unscrewing of the spigot part out of the tubular part.
3. A connector member according to claim 2 in which the threads on the spigot part have a slight inward taper from said unthreaded portion.
4. A connector member according to claim 2 or claim 3 in which said unthreaded portion is abutted against the end of a rod of flexible material located within the tubular part to prevent the spigot part screwing into the tubular part.
5. A connector member according to any one of
