AUGUST EVERSON', 0F BIG- SANDY, MONTANA.
Application fi1ed July 16,
T 0 all whom it may concern:
e it known that I, AUeUs'r EvEnsoN, a citizen of the United States, residing at Big Sandy, in the county of Chouteau and State of Montana, have invented new and useful Improvements in Reamers, of which the following is a specification.
This invention relates to a drill, the principal object of the invention being to provide means for boring a hole of greater di ameter than the casing so as to provide room for the couplings of the casing, while permitting the drill to be passed through the casing.
Another object of the invention is to provide the bit with a movable part so that the said movable part may be moved into a position to permit'the drill to pass through the casing with means for moving the movable part to assume its normal position when it strikes the bottom of the casing;
This invention also consists in certain 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 my 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 a sectional view showing the device in use in a casing.
Fig. 2 is an enlarged side view with the movable part of the bit in extended position and ready to be drawn through the casing.
Fig. 3 is an edge View of Fig. 1.
Fig. e'is a longitudinal sectional view.
F ig. 5 is a detail View showing thefconstruction of the spring.
In these views 1 indicates the drill shank and 2 the bit which is of greater width than the shank and is also of greater width than the diameter of the casing so that it will bore a hole of'larger diameter than the casing to make room for the couplings in the casing, said casing being shown at 3 in F 1g. 1. In order to permit the drill to pass through the casing I provide means for contracting the bit part, such means consisting in making a portion at of the bit part movable. This part 4 fits in a substantially wedge shaped recess .5. formed in the head of Specification of Letters Patent.
Patented Nov. 30, 1920. 1920. Serial No. 396,628.
the bit so that the pressure upon said movpart 4 is secured to the side members 6 in any desired manner. These side members rest upon the sides of the shank and are slidably secured thereon by means of the bolt 7 which passes through the shank and through the inclined slots 8 formed in the said side members. Guiding pins 9 are carried by the shank and engage'the inner edges of the side members for preventing lateral play of the side members. The side members are held in raised position with the movable part of the bit in this recess by means of the springs 10 which are secured to the sides of the shank and have their lower ends engaging the upper ends of the side members. The contacting faces of the springs and side members are provided with teeth 11 for interlocking with each other.
It will thus be seen that when the movable part is drawn out of its recess the side members will move at an incline toward the head end of the shank so as to throw said movable part in front of the other part of the bit, thus contracting the head of the bit and permitting it to pass through the casing. As soon as the movable part of the bit strikes the bottom of the hole it will be forced back into its recess and the springs engaging the side members will hold it in this position while the drill is being actuated. When the drill is to be withdrawn from the casing it is simply necessary to raise the drill sharply to cause the bit to strike against the bottom of the casing. This blow will cause the movable part to be moved downwardly out of its recess and in front of the other part and thus permit the device to be drawn from the casing.
It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.
I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.
What I claim is 1. A drill of the class described having a recess in its bit end, a movable bit part fitting in said recess, side pieces secured to said movable part and engaging the sides of the drill, guiding means for giving said side pieces a downwardly and inclined movement to throW the movable part in front of v the other bit part and spring means for holding the parts in raised position.
2. A drill of the class described having a Wide bit end having a recess in one side thereof, a movable bit part fitting in said recess, side pieces secured to said movable part and having inclined slots therein, a bolt passing through the drill and said inclined slots, a guiding pin in the bit engaging the 10 nner edge of eachslde piece and a sprlng plate secured to each side of the drill and having its end engaging the upper end of each side piece.
In testimony whereof I afix ms signature. 15
AUGUST EVi ERSON.
