AUTOMATIC TAPERING AND CUT-OFF TOOL.
Specification of Letters Patent.
Patented J an. 3, 1922.
Application filed January 28, 1919. Serial No. 273,675.
To all whom it may concern:
Be it known that I, CHARLES UEBEL- MESSER, a subject of the German Empire, residing at New York City, in the county and State of New York, have invented. certain new and useful Improvements in Automatic Tapering and Cut-Off Tools, of which the following is a clear, full, and exact de. scription.
The object of my invention is to provide a movable tool-bit-support adapted to carry one or more cutting knives, better known as tool-bits for the purpose of cutting a stock bar longitudinally, a predetermined shape, and to cut off the product when finished automatically or by human assistance.
Referring to the drawings,
Fig. 1 is a top view of the device embodying my invention.
Fig. 2 is a front elevation partly in crosssection.
Fig. 3 is a partial cross section of the movable tool-bit-support.
Fig. 4 is a longitudinal cross section through the device.
Fig. 5 is a side elevation of the device.
Fig. 6 is another side elevation.
Fig. 7 is a cross-section of a modification of my device.
Fig. 8 is a front view thereof.
As shown in Fig. 1 the general support 1 is usually fastened in the turret of a screwmachine or the tail stock in a lathe. On this support is mounted the slidable toolbit support 2, which carries two tool bits 3 and 4. The front plate 5 holds the tool-bit-support 2 in the general support 1; the work stock bar 6 enters through the front plate 5 (see Fig. 4) and abuts against the piston 7, said piston is forced back into the main support 1 (wherein it slides) by the work bar 6. To the piston 7 is attached a flexible band 8 which lies around the circumference of pulley 9 and is fastened thereto at point 9, therefore as piston 7 slides back in the support 7 it pulls on the band 8 and the band rotates the pulley 9. The pulley 9 is fastened on shaft 10 (see Fig. 2) and the shaft 10 carries on its other end a cam member 11, having a groove 11, said groove engages the pin 12, said pin 12 is fastened in lever 13 and said lever 13 is pivoted on lever The lever 14 is pivotally mounted in support 1, on axis 15 and has a pin 16 projecting into the groove 17 on ad justment knob 17 this knob 17 is mounted into the slidable support 2, any movement transmitted to the levers 13 and 14 by the member 11 will be transmitted to the movable tool-bit-support 2. It is therefore seen that the cam groove 11 controls the longitudinal shape to be cut on the work bar 6, the slidable support 2 is provided with a tension spring 18 (see Fig. 3) therefore the levers are under pressure in the groove 11 when the cam member is revolved to the end of the groove 11 then the groove 11 takes a longitudinal direction 11 (see Fig. 1) which will withdraw the tool-bit 3, and the tool-bit 4 will cut off the work. After the cut-off product has fallen off the piston 7 is free to return to its original position by the pull of the band 8 which is being pulled by the pulley 9. The pulley 9 has on its interior a clock spring 19 (see Figs. 2 and 4) and a new operation can commence. Around the pulley 9 is a cover 20 which excludes dirt and chips from interfering with the pulley 9, the sliding tool-bit support is threaded to receive the adjustment stud 17. (See Figs. 2 and 3.) As this stud is screwed in or out it varies the diameter of the work to be cut and still stays in operative connection with the lever 14, the stud can be expanded by means of the conical screw 21. The pin 16 is movably mounted in lever 14 to allow adjustment of the length of leverage between pin 16 and axis 15. When the adjustment has been completed, pin 16 is locked in position. It is readily seen that whatever the contour, cam member 11 controls the shape of the product and a great many forms can be made.
In Figs. 7 and 8 I have illustrated a modification of my device. I
As shown in Fig. 7 the main support 23, carries the slidable tool-bit-support 24. This slidable support spring 25 which presses said support 24 against the slidable guide 26. This slidable guide is pushed by the work bar 27 and when the end of the sliding guide 26 has assed the slidable tool support 24 at point Q X then the tool-bit-support 24 will snap forwardand the tool-bit 28 (that has heretofore cut the circumference of the stock bar 27 will also cut off the product. The toolbit-support 24 must then be drawn back to allow the sliding guide 26 to fall back into starting position. Spring 29 then returns the guide 26. The operations of both of is under pressure of the the herein described devices employ the principles of head-on pressure against the material to be worked.
What I-claim as my invention is:
1. A machine tool attachment consisting of a main support in combination with a variable tool-bit support therein, said toolbit adapted to take a longitudinal and transversal out successively and means to control the position of said variable support with relation to the Work, said means operative by the progressive work itself.
2. A machine tool attachment consisting of a main support in combination with a variable tool-bit supporting member, a sliding member abutting against the work, means interposed between the variable tool-bit support and the sliding member to transmit motion from one to the other, and means to operate the variable tool-bit support for cutting of the product.-
3. A machine tool attachment consisting of a main support in combination with a variable support for a plurality of tool-bits, a sliding member abutting against the work, a cam operating the variable support, means between the cam and the sliding member to transmit motion from one to-the other, variable levers interposed between the cam and the variable tool-bit support, a micrometer adjustment on the variable tool bit support and locking means therefor.
4. A machine tool attachment consisting of a main support in combination with a movable tool-bit support mounted therein, a second movable member therein, said second movable member changing its position in the main support as said main support is being moved toward the work, and means interposed between said second movable support and the tool-bit support whereby motion is imparted from one to the other for the purpose of facing, and cut-off the product as and for the purpose described.
Signed at New York City, N. Y. this 21st day of January, one thousand nine hundred and nineteen.
