489,642, filed April 13, 1909f This application filed: June 2, 1911. Serial No. 630,387.
. Taall whom it may coat/em Be it knownthat I, ANDREW SMITH, citizen of the United States, residing at San Mateo, in the county of San Mateo and State of California, have invented a new and useful Process forMaking Well-Casing,
of which the following is. a specification insuch full and clear terms as will enable those skilled in the artto construct and use the same.
This invention relates toaprocess of pro- .the object beingv to produce a] narrow slot v the art that it is not possible by the ordimeans whereby an indefinite number of slots.
sufficiently fine to exclude fine sand in metal pl ates of any desired thickness.
Itwill be understood by those skilled in nary punching processes to produce openings In a metal plate. of the harder metals with a p m'ch whose smallest dimension is less than the thickness of the plate to .be-
punched, such punches being unable to stand the repeated punching operations. I
This invention therefore seeks to provide narrower than the thickness of the metal sheet may be produced therein with punches which will withstand the heaviest usage.
Another object of the invention is to produce a slotted metal sheet which will have the walls of, the slots comparatively smooth, thereby increasing the life of the metal sheet" since with metal sheets having fine 0 enings broken, therein in the production 0? the so-called cracked casings, the
roughened edges of the openings begin to rust very quickly and in a short time the opening is enlarged so much as to be practically useless for the purposes intended.
Another object of forming casing in the manner herein described lies in the fact that the smooth walled slots produced in the casing are very easily galvanized and may be so galvanized after the casing has been finished without danger of stopping up the slots so formed.
In the drawings in which the same numeral of reference is applied to the same portion throughout the several views, Figure 1 is a side elevation of a portion of well casing slotted in the manner hereindescribed, Fig. 2 is a plan view thereof, Fig. 3 is a plan of a plate which has been punched to form projections on one side thereof, 4
is a side elevation of the plate shown in the Fig. 3, Fig.5 is a sectional view of the plate shown in Fig. 3, Fig. 6 is a plan view of a plate which has been produced by forming projections on. opposite sides thereof, the -metal adjacentthe slits formed being moved in opposite direction something more than one-half the thickness of the plate, Fig.'7 1s a side elevation of the plate shown in Fig. 6, Fig. 8. is a sectional View of the plate shown in Fig. 6, Fig. 9 is a plan view of a plate which has been formed by moving the metal on opposite sides of the several slits parallel to its initial position as would be the case with a straight and punch, save that the ends of the projection thus formed are rounded, Fig. 10 is a view of the plate shown in Fig. 9 in end elevation,-Fig; 11, is a View of the plate shown in Fig. 9 in side .elevation, -F ig 12 is a sectional view of the well casing in which there are a series of slots 2- formed, said slots extending around the casing in several parallel series.
-In Fig. 3 a plate 8 has projections 4::
formed therein, said projections being pressed up from the body of the metal forming the plate slightly more than the total thickness of the plate, the total width of the metal distorted by the punch being greater than the thickness of the plate, whereby it is possible to use a very strong and solid punch. This plate is shown in side elevation and in section in F igs, 4 and 5.
In Fig. 6 there is shown a plate having projections 6 formed therein on one side and projections 7 formed therein on the reverse side, the object being to move the metaladjacent the slots as short a distance as possible, thus stretching it the minimum plate shown in Fig." 9, Fig. 13 is a plan while the latter are on the opposite side thereof. :This form of projection is produced by means of a straight end punch having its corners curved to prevent cutting the metal at the end of the punch.
After the production of any one of the above mentioned plates, the punch forming the projections'therein may be struck laterally to upset the edges of each of the projections thus produced, as indicated at 11 a on the plate 8. After the edges of the proj ections have been upset, the plates may then be passed through rolls which will again return the projections to the plane of the plate, thus making a perfectly smooth plate save for the slight projections at the edges of the projections where they have'been' up-,
set. Such a plate is shown in plan in Fig. 13 and in sectional view in Fig. 14, the amount of the upsetting being exaggerated I in the latter figure for the purpose of illustration.
It will of course be understood'that sinceit is contemplated that this product shall exclude from the pipe all fine materials such as sand, the openings produced must be very small. In the case of oil wells, the openings are about one inch long by onesixteenth of an inch wide in three-eighths to one-half inch casing, while in the case of water wells the openings are about" onethirty-second of an inch in width. or less, as may the condition of the soil in which the well is bored, while in the case of drain tiling, the slots willbe from one-thirty-second of an inch downwardly depending upon the soil in which the tiling is placed.
It will be obviousthat the plate may be used with or without returning the projections to the plane of the sheet, the only requisite being that the upsetting be of such an amount as is deemed necessary to, produce the desired slits in the finished plate.
- Having thus described my invention what I claim as new and desire to secure by Letbe' determined necessary owing to .the sheet, as set forth.
in the presence of ters Patent of the-United States,,modifications withinthe scope of the claims being expressly reserved, is as follows: 1. The process of making plates for well casings comprising forming a plurality of slits in a plate by a shearing operation and laterally displacing the metal upon one side of each slit, thus causing the edges to project beyond the plane of the plate, and then upsetting the projecting edges. i I 2. The process of making plates for wel casings comprising forming a pluralityoi slits'in a plate by a shearing operation an laterally displacing the metal upon one side of each slit, thus causing the edgesto project beyond the plane of the plate, then upsetting the projecting edges, and pressing the laterally. displaced portions into the plane of the metal sheet.
3. In a process for the production of well casing, forming a series of projections in ametal plate by pressing adjacent portions thereof on opposite sides in opposite directions a distance slightly more than one-half the thickness of the metal late, thus forming a slit'between said portions, as set forth.
4.- In a process for the production of well casing,'forming a series of projections in a metal plate by ressing adjacent portions thereof on opposite sides in opposite directions a distance slightly more than one-half the thickness of the metal plate thus forming a slot between said portions, and upsetting the edges of the projections thus formed, as set forth.
5. In a process for production of well,
casing, forming 'a' series of-projections in a metal plate by pressing portions thereof on opposite sides in opposite directions a distance slightly more than one'half the thickness of themetal plate, thus'forming a. slit between said portions, upsetting the edges thus formed, and then pressing the projections back into the general plane of In testimony whereof Ihave hereunto set p my hand this 23 day of May-A. D. 1911', the two subscribed witnesse's.
