ALBERT PETEREIT, OF NEV YORK, N. Y., ASSIGNOR TO THE PETEREIT i MANUFACTURING COMPANY, OF NEW YORK.
TAPER-TURNING IVIACHINE.
SPECIFICATION forming part of Letters Patent No. 567,549,401ated september 8, 1896. Application ined .my 25,1894. sanare. 518,594. ci@ modem To all whom, t may concern:
Beit known that I, ALBERT PETEREIT, a citizen of the United States, and a resident of New York, in the county of New York and State -of New York, have invented certain new and useful Improvements in 'laper-'lurning Machines, of which the following is a specification.
This invention relates to turning` and truing attachments for valve-plugforming machines and it consists in the construction and novel arrangement of parts as hereinafter set forth.
I will describe a machine embodyingr my invention, and then point out the novel fea tures in the appended claims.
In the accompanying drawings, Figure l is a plan view oi a plugforming machine embodying my invention. Fig. 2 is a section on the line 2 2 of Fig. l. Fig. is a section on the line 3 3 of Fig. l. Fig. 4 is a side elevation, on an enlarged scale, of my invention as attached to the machine. Fig. 5 is a longitudinal section of said attachment, and Fi (i shows a valve-plug as formed and ready to be cut from the rod.
Referring by letter to the drawings, A designates the bed-plate of the machine, upon which is mounted the chuck A', its spindle, and the driving-band pulleys A2.
The valve-plugs a are formed and cut from a metal rod a', which is fed through the hollow spindle and chuck in the usual manner.
AS is a rotary tool-holder mounted on a longitudinally-reciprocatin g carrier A4, mounted in a guideway c?, adjustably attached to the bed-plate A. Motion is imparted to the carrier ALl by means of a hand-lever as, having pivoted connection with the guideway a2 and with the carrier. The tool-holder A3 is designed to hold the tools successively brought into play for forming a plug, such, for instance, as a beveling or tapering tool, a boring-tool, a tool.
The machine has attached to it the usual head-forming and cutting-off tools a a5.
I will now describe my planing or turning attachment. It is to be understood that my attachment is designed to true-up the previously formed taper of a valve-plug.
tapping-tool, and a shouldering-V B designates an adjustably-iixed guideplate for the tool-carrier B. The guide-plate is secured by means of a pivot b' to a .tor- Waiallyextending tongue on a lever B2, which is pivotal] y attached to a standard l), extended from the bed-plate A, the pivot D' engaging with the tongue of. the lever and passing through a hole in the stem portion h2 of the guide-plate. It is obvious that the plate B maybe maintained in aposition to cause thc planing-tool to operate in a horizontal plane, or that it may be turned on its pivot to cause the tool to cut at any desired angle or taper relatively to the vertical `standard l). To se cure the plate as adjusted, I may employ a set-bolt or number ot' set-bolts lr", which. pass through holes in the stem portions b2 and through elongated or enlarged openings b4 .in thetongue ol the lever, as plainly shown in Fig. 5. J ain-bolts lipassing through tapped holes in the lever B2 and engaging against the end of the stem portion h3, may be employed in adjusting the holder,
A principal feature ot' my invention resides in means for adjusting' thc turning or cutting tool vertically to cut on or below the center of a plug. This adjustment is necessary to accommodate the tool to the varying hardness of metals, that is, with a soft metal the tool may be placed to cut below the center and may be raised toward or to the center for harder metal to make a liner cut. Heretofore it has been necessary to grind the tool to a bevel for the purpose. My adjusting device consists in a screw B3, extended vertically through a tapped hole in a lug extended from the standard l), and upon the upper end of which the lever B2 may be rested. Obviously, by manipulating the screw the lever may be raised or lowered and the tool consequently adjusted.
The tool-carrier S' has its lower edge seated in a groove c in the lower portion of plate B,
and its upper edge is seated'in the channel or groove of a plate (l. The channeled plate O is vertically adjustable relatively to the plate B, so that it may be caused tobear more or less on the carrier B'. lt is guided in its movements and vheld in position by means of bolts c', passing' through notches in the plate O, and set-screws c2 may be em- IOO ] loycd i or i orcin g the channel-plate upon the toolcarricr. -The tool-holder B'- is moved or returned to its outward or normal position by means of a spring C@ At one end this spring is shown as abutting against the end wall of a longitudinal hole in the tool-carrier, and the other end is shown as abutting against the end wall of a tubular guide C2 in the guide-plate B. The hole in the tool-carrier is sufficiently large to allow the tube G2 to pass into it as the carrier is moved inward. rihe cutting-tool is secured by means of a set-screw d to a projection D on the carrier B. The length oi outward movement of the carrier B may be adjusted or regulated by means of a set-screw (l, passing through a tapped hole in a bracket d2, screwed to the plate B. Inward movement is imparted to the tool-holder B by an inward movement of the tool-holder carrier A4. An arm cl3 eX- tends from the tool-holder A3 and is designed to bear against the outer end of the carrier B'. lt does not bear directly against the carrier, but has an antitriction-roller dfi, which bears against the carrier.
The operation is as follows: After using the tapering-tool on the holder A3 to roughly turn the plug to a taper, and after certain others of the tools have been operated, the tool-holder is rotated to bring the arm d3 into position to engage the carrier H. Then, by moving the carrier A4 forward, the carrier B is moved longitudinally, and consequently the tool C" is moved over the plug from its small end to its -iarge end. Upon returning the carrier A4, the spring C2 will move the carrier B/ and tool in the opposite direction. The tool C3 cuts on each of its movements. Ot' course, during the operation the rod a is in rapid rotation.
Having described my invention, what l claim istongue to which said guide-piece is pivoted, a
longitudi:cally-movable tool-holder mounted in said guide-piece, the lever for moving said holder in one direction. and the spring for moving it in the opposite direction, substantially as specified.
2. The combination with the guide-piece and the lever to which it is pivoted and the adj ustin gscrcw extending laterally from the standard to which the lever is fulcrumed, whereby said lever may be adjusted to vary the angle at which the edge of the cuttingtool is presented to its work, substantially as speciiied.
3. An attachment for machines for forming valve-plugs, the same consisting of a lever having adjustably pivoted thereto, a guideplate B, and a tool-carrier, movably -located therein and the lever and spring for moving said tool-carrier in opposite directions, substantially as speciiied.
it. The combination with the lever of the guide-plate, adjustably fastened thereto, and
carrying a movable tool-carrier, of the bind' ing-bolts h5, whereby the device is held in adjusted position, substantially as specified.
5. ln a valve-plug-forming machine, the combination with the lever B2 and the stan dard b to which it is pivoted of the bindingbolts b3 passing through elongated apertures b4 and the feed-guide adjustable by means of said binding-bolts, substantially as specified. Signed at New York, in the county of New York and State of New York.
