To @ZZ whom, t may concern:
Be it known that we, HELLMUTH LANGER and GEORG BOOK, subjects of theGerman Em'- peror, and residents of Steglitz,. near Berlin, in the Empire of Germany, have invented a new and Improved Tool-Holder, of which the following is afull, clear, and exact description.
VOur invention relates to a new tool-holder especially adapted to be used in connection with lathes.
An'essential feature of the inventionconsists in the special construction of the locking device, another feature of the invention being the arrangement of the cutting-tool.
The various features of this invention will be hereinafter described, and'pointed out in the claims. -Y
In the accompanying drawings, Figurel is a side elevation of the tool-holder with the tool. Fig. 2 is an end view of the tool-holder. Fig. 3 is a plan view of the tool-holder corresponding to Fig. 1. Fig. 4 shows a longitudinal section of the tool. Fig. 5 shows the locking device. Fig. 6 is a longitudinal section of a modification of the tool-holder.
The tool-holder consists of abody portion a, which is rectangular in cross-section or has four flat sides, (indicated by 1, 2, Sand 4 in Fig. 2.) At the forward end the body portion is made substantially conical or tapered from the sides 3 and L toward the corner formed by the junction of the sides l and 2. The body is provided witha tool-receiving hole a, which is, arranged at adownward or acute angle with relation to the top and bottom sides of the body and also at an acute angle transversely of the body or with relation to the edge ff. Thisopenng for the tool c passes out through the apex of the conical formation or at the corner 1 2. The body is provided with a-longitudinal bore 02 in which is arranged a locking-rod This bore is arranged at an angle with relation to the body and communicates with the hole a. The rod b is tapered at its end engaging with the tool c, and it is prevented from rotary movement by means of a pin 'g extended from the body into a channel b2, formed in said rod. The tapered portion of said rod is indicated vcylindrical portion 0 of the screw.
at At the rear end thev rod has rotary connection with a screw-block d. As here shown, the end of the rod 7) is provided with a ball It, seated in a'soclret Z, which passes into a recess a5 in the body portion, and as a means for holding the ball in said socket meinber the end wall m of the socket member may be crimped down uponthe ball,as clearly indicated in Fig. 4. By this construction the rod is moved both inward and outward by the turning of the screw-block.
A block @l has a threaded portion n for engaging with the interior thread a3 of the body,
and rearward'of this threaded portion is an enlarged chamber a* for receiving an enlarged By this construction dust or dirt will be prevented from reaching the screw-threads.
In Fig. 6 we have shown the rod as connected to a screw d by means ot' a pin s, having a head t, which engages against the outer end of said screw. The -inner end u of this rod I) is made conical in form, so that it will operate against the tool c, even if it should be turned with the rotary movement of the adjusting-screw.
Having 'thus described our invention, we claim asnew and desire to secure by Letters Patentl. A tool-holder comprising a bar having a tool-opening and a ,thrust-pin opening,the toolopening extending from near one side at the front of the bar obliquely toward the rear of the bar, a thrust-pin in said thrust-pin opening, a screw for actuating said thrust-pin, and a swivel connection between the screw and the thrust-pin.
2. A tool-holder comprisnga bar having a tool-opening and a thrust-pin opening, the toolopening extending from near one side at the front vof the bar obliquely toward the rear of the bar, a thrust-pin arranged in said thrustpin opening having a reduced extension, a sleeved screw arranged on said reduced extension, and means for securing said extension in said screw for forming a swivel therewith.
3. A toolholder comprising a body or shank having a cutter-receiving opening at an acute angle to its longitudinal axis and a I ol cutter therein, and having a longitudinal bore intersecting the cutter-receiving opening adjacent that end from which the cutting edge of the cutter projects and inclined to the axis of the shank, said bore being also inclined to the axis of the cutter-receiving opening at a lesser angle than that formed by the axes of the shank and cutter-receiving opening, in combination with a rod in said bore, arranged to have one end bear upon the side of the cutter, and means to force the rod endwise, substantially as described.
4. A tool-holder Comprising the holdingr bar with a tool-opening therein` and a thrustplu opening arranged on a suicient slant to the tool-opening to effect a binding action,
