CASING COVER AND TOOL HOLDER.
Application filed May 19,
This invention relates to the type oftools for deep wells designed to be placed upon the casing and cover the same to prevent anything from being thrown into the well and which is adaptedto hold a able, rod or other part to prevent its dropping into the Well.
in accordance with the present invention, (he cover is made in similar halves or sectiorna, which are pivoted at one end and made secure at the opposite end by a pin which is selflocliing to prcrent casual displacement.
The invention further contemplates a positive connection between the slips and sec tions of the cover to prevent misplacement of the slips and insure having them at hand for instant use when required.
iVhile the drawings illustrate a preferred embodiment of the invention it is to be understood that in adapting the means to meet specific needs and requirements, the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.
For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawings hereto attached, in which Figure 1 is an elevational view of a casing cover and tool holder for deep wells, embodying the invention, the cover being in section on the line 1-1 of Figure 2,
Figure 2 is a top plan view of the cover, the slips being in section,
Figure 3 is a detail sectional view on the line 8'3 of Figure 2, a portion of the slips being broken away, and
Figure 4c is a detail perspective view of one of the slips, showing the same on a larger scale.
Corresponding and like parts are referred to in the following description and desig nated in the several views of the drawings by like reference characters.
The numeral 1 designates the upper end of the casing of an oil well, which is adapted to receive the well tubing, not shown, and through which the usual tools are introduced when boring, bailing, or otherwise preparing the well for action.
In accordance with the present invention, the casing cover comprises similar parts or 1926. Serial No. 119,262.
The slips 9 may be of any approved construction, and are disposed upon opposite sides of the usual opening through which the cable, rod, or other part passed. The gripping faces 10 of the slips 9 may be corrugated, or otherwise formed to prevent possible slipping of the part gripped between the slips. In accordance with the present invention, a longitudinal groove or channel 11 is formed in each side of each of the slips adjacent and parallel with the back thereof. The grooves or channels 11 receive lugs 12 of retainers 13 which are secured to the sections of the cover. A pin 14 or like part is fitted in a transverse opening formed in each of the slips 9 in line with the grooves 11 and its ends project into the grooves to close the lower ends thereof and prevent casual disengagementof the slips from the cover when properly fitted thereto. Rollers 15 are fitted into recesses formed in the respective. parts I lit 2 and 3 and minimize the friction incident to movement of the slips 9. Theretainers 13 and the rollers 15 are located near the top of the cover and in consequence, the slips 9 may be adjusted to the position substan tially as indicated in Figure 1, thereby admitting of a part being readily placed in position and the slips closing upon such part to grip and hold the same.
The cover completely closes the casing and prevents anything from being thrown into the well and the slips firmly grip a cable, rod or other part to hold it in the required position and prevent the tool carried thereby from dropping into the well.
Having thus described the invention, 1 claim:
1. A tool for deep wells comprising a casing cover including similar sections pivotally connected at one end and having over lapping portions at the opposite end, and a locking pin having a head at one end and adapted to pass through registering openings "formed in the overlapping end portions and having a part adjacent the head reduced to provide a shoulder for the overlapping end portion of a section to engage over to prevent casual withdrawal of the pin.
2. A deep well tool comprising a casing cover having the usual opening, slips within the opening and provided in their opposite sides adjacent and parallel to their backs with grooves, retaining means at the top of the cover including lugs entering the side grooves of the slips, and stop means closing the lower ends of the grooves in the sides of the slips and adapted to coact with the said lugs to prevent displacement of the slips.
3. A deep well tool comprising a sectional casing cover recessed to receive rollers, connecting means for securing the sections together when adjusted to operative position, slips having longitudinal grooves formed in opposite sides, rollers mounted in said recesses otthe cover sections and retainers on the parts of the cover engaging the longitudinal grooves of the slips to prevent displacement thereof.
In testimony whereof I aflix my signature.
