DOUBLE-UNDERREAMER SETTER.
Application filed October 10, 1914.
liability of injury to the workman.
In the drawings, accompanying and forming part of this specification: Figure 1 is an elevation illustrating the application of my novel appliance to a double reamer. F i g. 2 is a perspective of the appliance per 86. Fig. 3 is a detail section illustrative of the manner in which the adjusting nut is secured in the body of the appliance.
.Similar numerals of reference designate corresponding parts in all of the views of the drawings.
The under reamer illustrated is of conventional construction, and among other elements comprises a body 1 and a key-carrying mandrel 1 in which is a central threadedsocket designed to receive the adjusting stem 2 of my appliance.
In addition to the stem 2 the setting appliance comprises a frame 3 and an adjust-.
ing nut 4. The appliance frame 3 is formed of a single piece of metal suitable to the purpose, and has a base bar 5 and arms 6 that reach at right angles from the base bar and are provided in their upper ends with notches 7. For the sake of increasing the stiffness and strength of the frame without rendering the same unduly heavy, both the base bar 5 and arms 6. are ribbed as inclicated, by 8. The base bar 5 is provided with a central smooth-bore aperture 9 for the loose passage of the stem 2 and is also provided with a depending collar 10 on the wall of which is an inwardly-extending projection 11, preferably a screw as shown. The
Specification of Letters Patent.
Patented Oct. 19, 1915.
Serial No. 866,130.
stem 2 is slightly tapered as shown, and is provided with an upper thread 12, a lower thread 13, and a head or finger-piece 14, the
tial groove 15, the latter to receive the projection' 11 which serves to swivel the nut in the collar 10. On the nut at is a handle 16.
In the practical use of the appliance, the frame 3 is set up against the base of the under reamer, Fig. 1, so that the notches in the arms of the appliance frame receive the fins 17 on the body 1, and the stem 2 is turned into the threaded socket in the lower end of the key-carrying mandrel 1. With this done, the nut (i is turned through the medium of the handle 16, whereupon the mandrel 1 will be drawn downwardly sufficiently far to permit of the key, the cutters and the setting ring of the under reamer beino' adjusted.
It will be gathered from the foregoing that a single workman can quickly apply my appliance to and manipulate it on an under reainer, and that incidental to the use of the appliance there is no liability of anything slipping and injuring the hands of the workman.
, Having described my invention, what I claim and desire to secure by Letters-Pat ent, is:
An appliance for the purpose described, comprising a U-shaped frame having notches in the ends of its arms, a stem having a threaded upper end and also having a threaded portion extending through the base bar of the frame, and a nut swiveled in the base bar of the frame and receiving and engaging the last-named threaded portion of the stem.
In testimony whereof I have hereunto set inv hand in presence of two subscribing witnesses.
