SAND IREAMER.
1 Application filedFebruary '7, 1927. Serial No. 166,500.
This invention relates to asand reamer for oil and gas wells and the like, the general object of the invention being to prov de a tool which has its cutter carrying portion 6 swiveled to another portion, with means for enclosing the swiveled part to prevent the same from being damaged by sand and other foreign matter. I
Another ob 'ect of the invention is to hing edly connect the lower portion of the tool with the upper portion thereof and to provide a spring for pressing the lower portion outwardly so that the cutters will engage the wall of the well and thus remove sand from the same.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.
In describing our invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of the device showing the cutter carrying portion swung outwardly in dotted lines.
Figure 2 is a view of the upper portion of the tool, the view being taken at rightangles to Figure 1.
Figure 3 is a sectional view through part of the device, showing the hinge and swivel connections.
Figure 4 isa view of one of the cutters.
In these views, 1 indicates the upper section of the tool which is provided with the tapered threaded part 2 which is adapted to engage a threaded socket of a standard drilling tool, this part 1 being provided with a wrench engaging part 3 whereby the threaded part 2 can be screwed or unscrewed from the socket of a drilling tool by a wrench. The lower end of the section 1 is provided with a flattened reduced part 4 which is formed with a long extension 5 at one side thereof. The
The cutter carrying shank l lis provided with an enlarged top part 15 which is of the same diameter as the section 6 and a stem 16 is connected with the upper part of the enlargement 15 and passes through a threaded bushing 17 which is adapted to be screwed into a socket 18, the walls of which are threaded. The stem is rotatably held in the bush- 2 ing by means of a nut 19 engaging the thread ed upper end of the stem 16, a pin 20 being passed through the upper end of the threaded portion to hold the nut in place. Thus the shank is swiveled to the section 6 and the swiveled parts are enclosed so that sand cannot reach them.
The shank 1a is of square shape in cross section and it is provided with the undercut notches 21 to receive the upper ends of the cutters 22 which are held in place by the rivets 28, each rivet holding a pair of cutters to the shanks. These cutters are of angle shape, as shown in Figure 4: so that their cutting portions will be located a considerable distance from the shank.
As will be seen, when this device is attached to a drilling tool and lowered in the well, when the tool is rotated the cutters will engage the sides of the well and free the same of sand and the like and as the spring holds the cutter carrying part of the device at an angle from the vertical, the portion of the well engaged by the device will be enlarged.
It is thought from the foregoing description that the advantages and novel features of our invention will be readily apparent.
We desire it to be understood that we may make changes in the construction and in the combination and arrangement of the several sion upon which it is pivotally mounted, said second mentioned section being longitudinally slotted for a portion of its length, an arnr depending from the first mentioned section and received by said slot, expansible means located between the'arm and the second mentioned section for moving the latter to an angular position with relation to the first mentioned section, means for holding said I second mentioned section in end to end relation with the first mentioned section, and a cutter carrying-shank detaohably connected with'the lower end of the second mentioned section.
2. A device of the character described comprising two sections arranged in end to end relation, a reduced extension depending from the lower end of the upper section, a relatively long arm depending from the same section at one side ofthe extensiolnthe second section having its upper end bifurcated to receive theextension upon which it is pivotally mounted, and formed with a longitudinal slot to receive said arm,-an expansible element arranged within the second mentioned section and bearing against saidv arm whereby the second mentioned section is moved to a position at an inclination to the first mentioned section, means for holding said sections in end to end relation against the influence of the expansible member, said second mentioned section having a threaded bore-in its lower end, a bushing threaded in said bore, and a cutter carrying shank including a reduced portion swiveled in said bushing. c
In testimony whereof we aflix oursignatures.
GEORGE A. MORRIS. OTIS C. 'BYRD.
