UNITED STATES PATENT OFFICE.
GILBERT o. THOMPSON, or DES MOINES, IOWA.
PIPE-CUTTER.
SPECIFICATION forming part of Letters Patent No. 377,725, dated February 7, 1888.
Application filed November 1, 1886. Serial No. 217,683. (No model.)
To all whom it may concern.-
Be it known that I, GILBERT G. THOMPSON, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Improvement in Hand Turning and Cutting Machines; and I hereby declare the following to be a full, clear, and exact description of my invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form apart of this specification.
My invention relates to hand turning-machines adapted to turn or out cylindrical and round tapering metal shafts; and it consists in the peculiar features of construction and novel arrangement and combination of parts, hereinafter fully described and claimed.
The object of the invention is to produce a light, durable, and portable hand machine adapted to turn and cut off shafting and piping. I attain this by the mechanism illustrated in the accompanying drawings. 7
Figure 1 is a side elevation ofmy improved machine. Fig. 2 is a front elevation looking from the right of Fig. 1. Fig. 3 is a rear elevationlooking from the left of Fig. 1. Fig. 4is a vertical section. Figs. 5 and 6 are views of detail parts, and will be hereinafter referred to.
Similar letters refer to similar parts throughout all the several views.
A represents a chuck having recessed boxes.
which is perpendicular to the bore of the chuck.
G is another and larger disk, with an'arm or lever, H, having an opening, I, in the center corresponding to the opening or bore through the barrel of the chuck A. In the back ofthe disk G is a circular recess, J ,in which is fitted the disk F of the chuck A, the disk F being held in the recess by the guide-clamps K K K, so that the disk F is free to revolve in the recess J and the disk G is free to rotate upon the disk F of the chuck A. On the face of the disk G and arm H are flanges or guides L L, which receive aslidin g block or tool-holder, M, carrying an adjustable cutting-tool, N, held in place by a clamp-plate, O, and set-screws l? P.
R'is a small shaft having on one end a handle, S, and mounted in the log T, which projects from the arm H. The shaftRisscrewed into the boss U of the tool-holder M, and by means of the handle S may be operated to feed the cutting-tool N in toward the center of the shaft or pipe operated'upon, or to draw it out.
V is a collar rigidly attached to the shaft R.
W is a spiral toothed wheel rigidly secured to the shaft R, which,with the collar V,forms shoulders that prevent the shaft R from moving longitudinally in feeding the cutting-tool in or out.
X is a sleeve which runs loosely upon astud, Y, and forms the handle grasped by the operator to rotate the armH and disk G upon the chuck A. The sleeve X is provided with a worm wheel, Z, made, preferably, integral therewith, which engages the toothed wheel W, and as the disk G, carrying the cuttingtool N, is being revolved by the operator (the sleeve X being firmly held in the hand) the I worm-wheel Z automatically feeds the cuttingtoolN toward the center of the pipe or shaft operated on. Upon one end of the stud Y, and rigidly secured upon it, is an eccentric-collar, a, one part of which is enlarged to form a shoulder, 11. The eccentric a fits into a hole in the end of the arm H and is held rigidly in place by a nut, c, which screws onto a thread cut on the end of the eccentric-collar aand draws the shoulder b tightly against the face of the arm H. When it is desired to adjust the cutting-tool, by sliding the tool-holder M,
is turned back again and the worm-wheel brought into mesh with the toothed wheel W and the nut c retightened. There is agroove made in the sliding block M, into which the cutting-tool N is placed, the cutting-tool being held therein by a plate, 0, secured by cap- 1 IOO E and the cutting'tool adjusted by means of the shaft R and handle S. The disk G is then rotated upon the disk F of the chuck A by the arm or lever H and the handle X, carrying the cutting-tool round the pipe or shaft to be operated upon, the cutting-tool being automatically fed to its work, in the manner hereinbefore described.
This machine may be employed for cutting oif piping or round bars of metal too large to be cut with a cold-chisel to advantage; but it is more especially adapted to turning up new shoulders on carriage axles or spindles that have worn until the boxing in the hub has too much lateral play on the spindle.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination of the chuck A, disk F, oppositely opposing jaws O, adjustabl y mounted in chuck A, rotatable arm H, having disk G, clamps K on the latter adapted to engage disk F, and a cutter mounted adjustably on arm H, substantially as set forth.
2. The combination of the chuck A, having recesses 13, disk F, jaws 0, received by said recesses B, set-screws for adjusting said jaws,
rotatable arm H, having disk G, clamps K on the latter adapted to engage disk Rand acutter mounted adj ustably on arm H, substantially as set forth.
3. The combination of the chuck having adjustable jaws, a rotatable arm having an enlargement perforated for the reception of the pipe, suitable means for securing said chuck loosely to said arm, a cutter mounted in a sliding block, and a rod mounted on said rotatable arm adapted to adjust said cutter and its block, substantially as set forth;
4. The combination of a rotatable pipecutting device having an operating-arm, a cutter mounted thereon, a rod mounted loosely on said arm and suitably connected with said cutter, a toothed wheel mounted on said rod,and a rotatable handle at the end of said arm having a worm wheel adapted to engage said toothed wheel and feed the cutter automatically forward as the arm is revolved, substantially as set forth.
