PROCESS OF MAKING WELL STRAINERS Filed March 2.3, 1928 A TTORNEYQ- TM etone.
lented June 17, 1930 @Fll GEORGE E. WILLERS, OF LAWRENCEBURG, INDIANA, ASSIGNOR TO A. I). COOK, INC., LAWRENGEBURG, INDIANA, A CORPORATION 0F INDIANA PROCESS OF MAKING WELL STRAINERS Application filed. March 23, 1928. Serial No. 264,221.
My invention relates to a process for making well strainers of novel type.
In the art it is old to provide a well strainer for deep wells, which consists of a selfsustaining framework with spirally wound wire secured around the framework with filtering orifices thus provided between the interspaced wires. The method of manufacturing such strainers is to provide grooved ribs with header members and to then wrap wire spirally around the ribs and to call: the metal of the ribs so that it will firmly retain the wires which provide the filtering area.
lVhile such a process of manufacturing well strainers provides an improvement over what was known in the art at the time this co-pending application was filed, I have since developed an improved process for making such strainers which, as a process is much simpler than my old process, and which provides a well strainer of improved construction. It is my object, therefore, to provide an improved process for making a well strainer which as the specification develops, will be shown to possess many marked im provements both in the quality of the work done and in the simplicity of carrying out the process of manufacture.
The above and other objects to which reference will be made in the ensuing description I accomplish by employing those certain steps in the manner hereinafter specified, which result in a pronounced advance in the art relating to such types of equipment.
Referring to the drawings Figure 1 is a side elevation of a well strainer in process of manufacture being made in accordance with my novel process.
Figure 2 is a sectional view of the parts shown in Figure 1.
Figure 3 is a side elevation of a strainer when partially completed.
Figure 4 is a sectional view of the strainer shown in Figure 3.
Figures 5 and 6 show sectional views of preferred types of strainer wire which may be used in the manufacture of screens in accordance with my process.
In carrying out my process I provide a mandrel 1 or other core which preferably has grooves 2 within which the longitudinal ribs 3 may be secured. A header or coupling piece such as that indicated at 4 in Figure 3, and which has grooves 5 within which the ribs may be welded, is then secured in place. It will be obvious that the coupling piece may be first mounted on the mandrel prior to the insertion of the ribs in the grooves in the header, so that the sequence of these several operations forms no part of my invention. The mandrel is then rotated and a rotating saw such as the one diagrammatically indicated at 6 begins to cut grooves 6 in the ribs within which the several turns of the spirally wound wire 7 may be secured. The filtering wire, shortly prior to the start of the groove cutting operation, is welded either against the lower surface of the coupling piece or in a slot formed therein. Next a spacing disc 8 and calking wheel 9 are started in operation and the filtering wire is seated in the slots or grooves formed by the saw, the turns are spaced apart by the spacing disc, and the calking wheel 9 treats the metal of the ribs so as to permanently secure the wires within the grooves in the ribs.
Thus the three operations of groove cut ting in the longitudinal ribs, spacing the distance apart of the filtering wires, which of course controls the sizeof the filtering area, and calking the filtering wires within the grooves is carried out in a continuous successive manner.
A shoe as indicated at 10 may be attached to the carriage and the carriage may mount the notch cutter, spacing disc and calking wheel. The shoe may be made to bear against the side of the wound wire and thus propel the carriage forward as the winding progresses.
hen the wire has reached approximately to the outer ends of the ribs, it is cut oif and the end is soldered or welded in position against another header which may be of similar shape as the header adjacent the end where starting operations begin. In this manner a process which allows continuous manufacture of av strainer of desired length and diameter is provided which avoids diiiiculties which were formerly encountered in Ind making self -sustaining strainers of this type.
If the ribs were first grooved, and the filtering wire was then inserted in the grooves loop by loop, and the calking operation was then carried out, the lower edge of each groove would be somewhat battered by the calking operation so that after calking one loop the wire would not seat properly within the next succeeding groove. It will be apparent that difiiculties from such a source are done away with in carrying out the operations of manufacture as have been noted.
The strainer itself is an improved article of manufacture inasmuch as each loop of filter wire is seated in a freshly cut groove. The cutting of each groove a spaced circular distance ahead of the calking tool allows the cut to be made in each rib after the metal which will form the upper wall of the groove has been calked in against the wire.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
1. A process for making a Well strainer, which consists in mounting a series of ribs on a support and securing a header at one end of the ribs, then in sequence cutting grooves in the ribs in spiral sequence, and a short interval thereafter spacing and treating the metal of the ribs so as to permanently secure a filter wire within the cut grooves so that a strainer is provided with filtering apertures between the spirally spaced wires.
