DEEP-WELL AUGER-STEM.
Specification of Letters Patent.
Patented J une 27, i916.
Application led January 8, 1915. Serial No. 1,241.
To alt 101mm 'it may vanvera Be it known that l, LoRAN E. maan-nerim., a citizen of the United States, and a resident of Omaha, in the county of Douglas and State of Nebraska. have invented certain new and useful lmprovementsin DeeplVell Auger-Stems of which the following is a specification.
My invention relates to tools and appliances for use in boring Artesian and oil wells.
It is the principal object of my invention to provide an auger-stem or drill-bar such that the use thereof, will insure the production of a straight vertical hole in broken or slanting formations, or under any conditions such that there would ordinarily be a tendency to deflect the drill or bit and produce a slanting or non-vertical hole.
A further object of my invention is to` provide a stem adapted to cause a rotary or whirling movement of the bit when the string of tools is dropped.
A further object of my invention is to provide a stem adapted to mix and agitate debris in the hole and prevent the formation of mud-rings on the sides thereof.
A further object of my invention is to provide a stem for use with an underreamer, whereby the enlarged hole made by the reamer is kept concentric with the pipe, so that the latter will follow down freely and without binding.
In the accompanying drawings Figure 1 is a vertical sectional view showing in use a typical string of drilling tools including an auger-stem embodying my invention, Fig. 2 is a similar view showing my augerstem in use in'connection with an underreamer, Fig. 3 is a side view of the augerstem alone, Figs. 4, 5 and 6 are transverse sectional views of the stern taken respectively on the lines -:v, y-y and a-a of Fig. 3, and Fig. 7 is a transverse sectional vvlew showing a modified sectional form of the helical wings of the stern.
`In carrying out my invention l provide an auger-stem of which the main body-portion has or consists of a plurality of ribs or wings l, said wings in transverse section extending radially to the longitudinal axis of the stem, and also being inclined or twisted so as to extend helically about said longitudinal axis. The diameter of the stem, from outside to outside of the wings,
is made very slightly less than the diameter of the hole or of the inside of the pipe in which the stein is to be used, the clearance `allowed preferably being only about one eighth oi' an inch all around. The pitch of the helical wings is made such that they will each extend from one-halt to once around the stem in the length thereof, the pitch of wings of the stem shown in the drawings being such that the wings extend half around in the length shown. The length of stem ordinarily used in practice would be from thirty to forty feet. At the upper end of the winged body-portion of the stem the same merges into a cylindrical collar of which a portion 2 is threaded so that a section of pipe may be screwed thereon for the purpose hereinafter set forth. Above the threaded portion 2 is a portion 3 which is slightly smaller in diameter and is provided with a number of encircling grooves or corrugations similar to the neck-portion of a rope-socket. Above the grooved portion 3 is an ordinary wrench-square 4 and threadedV pin 5. At the bottom of the winged body-portion the same also merges into a cylindrical collar-portion at the lower end of which there is formed the usual threaded box 6 and wrench-square 7 The stem is preferably made of steel, the winged portion being formed by suitable rolls arranged at angles such as to produce the desired spiral or helical twisting of the wings. The end-portions of the stem are made b machining off the rough stock left by the rolling operation, and said end-portions may be welded to the winged body-portion should it be found inconvenient or difficult to form the stock for said end-portions from the saine piece used in making the wingedbodyportion of the stem. rllhe simplestV sectional forni of the wings is indicated in Figs. 5 and 6, but it may be desirable to have the sides of the wings concave as shown in Fig. 7, although the latter form is somel0 what more diliicult to operations.
ln the use of the stem for ordinary drilling operations, a suitable drill or bit 8 is produce by rolling connected with the lower end of the stem,
the rope or cable 1l extends up to the usual 110
