AUGUST LOEHNER, OF SI. IJOUIS, MISSOURI.
COMBINED RATCHET-DRILL AND DIE-STOCK.
QPECIPICATION forming part of Letters Patent No. 366,965, dated July 19, 1857.
Application filed August 21, 1886 To all whom, it may concern.-
Be it known that LAUGUs'r LOEHNER, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Combined Ratchet-Drills and Die-Stocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to ratchetdrills and die-stocks; and it consists in an improved construction adapted for the purposes of such tools, as hereinafter described and claimed.
In the accompanying drawings, Figure l is a perspective view of my improved implement adjusted for applicationto a drill. Fig. 2 is a plan view of the same, the upper plate being removed. Fig. 3 is a section taken on line m 00' of Fig. 2. Fig. 4 is a plan view of the frame or casing of the implement, the drill mechanism being removed and a die being placed therein. Fig. 5 represents a die formed to fit in the housing when the die-stock is required. Fig. 6 represents the'main frame of the implement, the other parts being removed. Fig. 7 represents a modified form of central cylinder with ratchet-wheel, &c. Fig. 8 represents in side and edge views a removable pawl, herein described. Fig. 9 illustrates in section the housing provided with a removable pawl.
The main frame of the device consists of the housing A, provided with a lever-handle, B. The housing has a removable upper plate, G, which is secured thereto by the screws a, which pass down through the housing, as shown. The central cylinder, D, being constructed with a ratchet-wheel, d, and drillsocket c, has bearings in the housing A, which is formed with apertures e e for such purpose.
The cylinder, ratchetwheel, and socket are formed of one piece of metal, the parts being thus rendered very strong and firm in position and not liable to be affected by the strain to which they are subjected in operating the drill. A pawl, 1), within the housing engages with wheel d, said pawl being pressed by a spring, f. The said pawl is provided with a fixed pin or stud, in, on its resting edge, which enters a Serial No. 211,510. No model.)
hole in the bottom of the housing and serves to retain the pawl and prevent it getting'out of place during operation.
The ratchet-cylinder and other parts in the housing A are readily removed as desired, so that a die may be placed in the housing, as hereinafter stated.
Different styles of ratchet-cylinders may be used in connection with housing A, the short cylinder shown in Fig. 2 being adapted for use in a drill-frame which carries a vertical screw by which the drill is pressed downward. The long cylinder shown in Fig. 7 contains a vertical screw, 8, by which the drill is forced downward, this form being often desirable where a drill-frame cannot be employed for want of space or means of fastening it in position.
E indicates a die for cutting screw-threads, formed to fit in the chamber of housing A, and by removing the ratchet-cylinder, pawl, and spring from the housing and substituting the die the implement is adjusted for a die-stock, convenient for use in repairing railway-tracks. When bolts are driven out and the screwthreads on them are damaged, or new threads are required to be cut, the die-stock is readily prepared, as above stated, for the purpose.
I claim- 1. The combination of a housing for drill mechanism with a lever-handle, a removable central cylinder, D, a ratchet-wheel and socket made in one piece withthe cylinder, and a removable spririg-pawl,substantially as set forth.
2. The combination, with the housing and its handle, of interchangeable drill mechanism and the screwcutting die, substantially as and for the purposes described.
3. In combination with the housing of a ratchetdrill mechanism,a removable pawl provided with a retaining-pin, which, when the pawl is in use, extends into a hole in the housing, substantially as described and shown.
In testimony whereofI a'ffix my signature in presence of two witnesses.
' AUGUST LOEHNER.
