Filed Jan. 15, 1926 Patented June 23, 1931 PATENT OFFICE WALTER E. KING, OF HOUSTON, TEXAS WELL SCREEN Application flled Januai-y 15, 1926. Serial No. 81,448.
being commonly known as button screens.
One object of the invention is to provide a screen of the character described. which 1s very simple in construction and may be cheaply producedand which is very durable in use.
Another object of the invention is to provide a screen of the character described embodying a screening button which, when insorted into the perforation of the pipe Wlll form its own means of engagement with the metal of said pipe.
A further feature of the invention resides in the provision of a well screen embodying a button which is so formed that, when inserted into the perforation of the screen pipe, will interengage with said metal to anchor itself in said perforation.
With the above and other objects in view the invention has particular relation to certain novel features of construction, arrangement of parts, and use. an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows an enlarged outside view of the screening button employed.
Figure 2 shows a side view of said button showing a central or knurled section with reduced cylindrical sections at the ends;
Figures 3 and 4 show end and side views respectively of a screening button which is knurled or toothed from end to end.
Figure 5 shows an outer end view of another type of screening button.
Figure 6 shows a side view thereof showing one end of this type of button reduced and blank and with the knurling parallel with the axis of the button.
Figure 7 shows a longitudinal sectional view of the button in place.
Figure 8 is an end View of the type of button shown in Figure 7 Figures 9 and 10 show outer end and side views respectively of a type of button having a single inlet therethrough which preferably flares inwardly.
Figure 11 shows a fragmentary elevational View of a well screen in which the screening buttons are employed and shown partly in section.
Referring now more particularly to the drawings. wherein like numerals of references designate similar parts in each of the figures, the numeral 1 designates a pipe which is provided with the perforations 2. The numeral 3 designates a screening button whose inner and outer ends are reduced as at 4 and 5 and blank, said button being knurled between said blank sections, as at 6. The blank extension l, employed in the form shown in all of the figures except 3 and 4, is provided to lit well into the perforation as an easy means for starting and will also act as a guide, or pilot when the button is being forced into the perforation under\pressure, or by a direct blow, as with a hammer. The peripheral knurling 6, may be straight, or parallel with the axis of the button, as. in Figure 6, or helical, as in Figures 2, 4, and 10. This knurling may also be of some other form, the preferred forms only being shown. The diameter of the knurled portion of the button is somewhat greater than the diam eter of the perforation. As a consequence upon being forced, or driven into the perforations 2 of the tube 1, the crests of the knurling will cut, or plough, into the metal of which the pipe 1 is made and preferably the buttons, or particularly the knurling thereof are to be harder than the metal of the pipe and capable of cutting into it. As the buttons are forced into the perforations they will displace metal which will flow into the channels 7, between the teeth of the knurled portions. The bottoms of these channels are countersunk beneath the surface of the reduced end 4, of Figures 2, 6 and 10 forming an abutting shoulder 8 and are likewise countersunk beneath the blank portion 5, Figures 1 and 2, thus forming the abutting shoulders 8'. As the displaced metal is forced into said channels it will engage behind the shoulders 8 to lock the button against withdrawal outwardly.
When the form shown in Figures 1 and 2 is employed the blank section 5 will tend to force the metal displaced by the knurling 6 back into its original position, thus forming an opposing shoulder against which the shoulder 8' engages and the screen buttons are thus locked against movement in either direction.
The type of screen button shown in Figure- 4 has not the reduced blank end for entering the perforation, but is slightly beveled at its entering end, its helical peripheral knurling will cut into the metal around the perforation and will retain its position therebyfin the and 10. These slits are provided for the inlet of surrounding fluid and are common to button screens now in common use.
The type of buttonshown in Figures 9 and 10 is of novel formation, having the port 10 therethrough, which if desired may be, flared inwardly as atll. -It often happens that screens are desired formed of large sections of pipe with very small perforations that are impractical to "drill; -In such case the pipe may be drilled with larger perforations and the buttons shown in Figures 9 and 10 then driven into said perforations.
' Attention is here called to the fact that when the pipe is perforated no subsequent operation is necessary for inserting the but- What I claim is 1. A well screen composed of a tubular section, having erforations, screen ,buttons in-said erfora-tions, the outer ends of said buttons ing provided with slits, the inner and outer ends of said buttons being reduced and blank, and the periphery of the buttons between such blank sections being provided with substantially parallel teeth.
2. A well screen composed of a tubular section, having perforations, screen buttons in said erforations, the outer ends of said buttons in provided with slits, the inner and outer en s of said buttons being reduced and blank and the periphery of the'buttons between such blank sections being provided with substantially parallel teeth, said teeth having sharp crests and their inner ends being beveled inwardl 3. A well screen utton'havin screening openings at its outer end and re need at its inner end, said reduced portion being blank,
approximately parallel teeth on the periphery of the button and extendin longitudinally thereof the inner ends of t e teeth being inwardl beveled.
4. In com ination with a screen ipe having'uniform diameter openings t erein, a
strainer button for each. of said openings, said button havin peripheral rojections thereon of greater ameter than t at of said openin whereb said projections may deform t e faces o said openings when said buttons are driven in place. a
In testimony whereof I have signed my name to this specification. I

tons. In other types of button screens the perforations must be counterbored to form shoulders against which the screen buttons are set, or said buttons are threaded into the perforations. These two are the most common types of button screens now in use.
Attention isfurther called to the fact that in button screens heretofore made the buttons are of soft metal such as brass or bronze, while in the screen herein described the buttons are formed of hard steel so that they will withstand the abrasive action of sand, which they are intended to exclude from the well, and should be noncorrosive to withstan the action of salt water, acids and other corrosive agencies so common in many wells.
I have shown only two forms of knurling to form means for holding the buttons in the pipe. It is apparent that the knurling of the buttons may be difierently formed to accomplish the same purpose and I do not 4 wish to be understood as having limited myself to the particular form shown and reserve the right to make such structural changes as will not depart from the scope of the appended claims.
