UNrTnn Tarts FRANCIS THOMAS, OF CINCINNATI, AND CHARLES H. IRWIN, OF MARTINS- VILLE, OHIO; SAID THOMAS ASSIGNOR TO SAID IRWIN.
DIES FOR MAKING AUGER BITS.
SPECIFICATION forming part of Letters Patent No. 378,408, dated February 21, 1888.
Application filed September 19, 1887. Serial No. 250,042.
To aZZ whom it may concern."
Be it known that we, FRANCIS THOMAS, a citizen of the United States, residing at the city of Cincinnati, in the county of Hamilton and State of Ohio, and CHARLES H. IRWIN, a citizen of the United States, residing at the town of Martinsville, in Clinton county and State of Ohio, have invented certain new and useful Improvements in Dies for Making AugerrBits, of which the following is a specification.
Our invention relates to dies used in making that class of auger-bits in which the bit consists of a central spindle or stem having a [5 single blade spirally around it, terminating at its lower end in a single cutter, the spindle or central stern terminating in a single screw.
The main object of these dies is to properly shape the spindle and give a uniform pitch to the blade. These dies might be termed finishing or straightening dies. The augerbit formed bythese dies is shown fullyin United States Letters Patent No. 306.907, dated October 21, 1884., and No. 361,522, of April 19, 1887. y
In the accompanying drawings,forming part of this specification, Figures 1 and 2 represent one set of dies, plan views.) Fig. 3 represents the auger-bit manufactured or finished by these dies. Figs. 4 and 5 represent another set of dies, (2. modification.)
After the auger-bit has been properly forged under a trip-hammer containing appropriate dies, and otherwise finished under header-dies ,5 and beingin the rough, it is brought under the action of these dies.
A B represent the faces of the dies. These dies are placed in an appropriate machine, and move toward each other laterally. One half of the auger-bit fits in one die and the other half in the other die, so that when brought together the dies hug every surface of the auger-bit. Across the faces of the dies is a groove, a, of a semicircular shape in transverse section. This groove is of the exact shape of the spindle b and of part of the blade 61. Obliquely across the groove a are the recesses d, in which fits the spiral rib c. The
. groove a, where it approaches the inclination of the convolution of the blade or rib e, is of a peculiar shape-that is, of the peculiar shape of the inclination of the convolution.
The
(No model.)
long groove a is to receive the shank of the auger-bit. It is semicircular in form in transverse section.
D represents a groove in which fits the cutting-point a? of the auger-bit. This point is cone-shaped, one-half of it fitting in each die.
In the die B there is a slight depression at Z) to receive the cutting-edge d of the auger-bit. In the present dies one half of the auger-bit is finished in one operation and the other half in another operation; but we may so construct the dies that they will take in the entire length of the auger-bit in one operation. One half of the auger-bit (that is, the forging) fitting in one die, A, and the other half in the other die, B, when the dies are brought to gether by any suitable means, they entirely encompass the auger-bit and obliterate every imperfection, bring the spindle between the convolutions and the shank in the same plane and center, make the spaces between the convolutions equidistant, and impart a uniform pitch to the rib or blade.
In the modification, instead of having a se ries of grooves and recesses, the groove E is provided, the entire auger-blade tilting into this groove.
' WVhat we claim as new and of ourinvention, and desire to secure by Letters Patent of the United States, is-
In dies for finishing auger bits, the dies A B, having a series of grooves, as a, corresponding to and receiving one-half of the central 85 spindle of the bit, and having a series of recesses, d, obliquely across the grooves a, said recesses in each die corresponding in shape to one-half of one of the single convolutions of the spiral rib, the grooves a being so shaped 0 at each end that they receive the inclined surfaces of the blade between the convolutions, and the recess D and depression Z), for receiving the cutting end and point of the blade or rib, and the recess a for the shank of the bit, 5
substantially as set forth.
