CLARK '.HLLSON, OF WORCESTER, MASSACHUSETTS.
Letters Patent No. 95,480. dated October 5,1869.`
IMPROVED MACHINE FOR. CUTTING TAPERS.
` The Schedule referred to in these Letten; Patent and making of the same.
Know all men by there presents:
t That I, CLARK JILLsoN, of the city and county of ,Worcestely and Commonwealth of Massachusetts,
accompanying drawings, forming a part of this speciication, in which- Figure 1 represents a side view of my machine Figure 2 represents a plan or top view;
Figure 3 representsa front view; and
Figure 4 represents a back view.
To enable those skilled in the art to which my inventionbelongs to make and use the same, I will proceed lto describe it more in detail.
In the drawings- A lis the base of the machine, provided with a rear supporting-piece, B, and a front supporting-piece, C.
Between the front and rear supporting-pieces is arranged a sliding table, D, which is retained in place by the side guides E E.
To the rear of the table D are secured two upright pieces F G.
1n the upper end of the piece G is journalled, at c, a spindle, H H; said `spindle y being fitted to move hack and forth withthe table D, the rear end 'H of the spindle being fitted to slide in the stand B'.
' A spur-gear, b, is fastened on the spindle H, which gears into another'spur-gear, c, on shaft J, which is journalled in the upright pieces F and G, and carries a gear, d, to gear, into the gear e on the end of the screw-shaft K, the front end of which screw-shaft is journalled and supported yin the upright piece F, while the rear end of the shaft is tted to slide freely through'a hole out or formed in the upright piece B.
Upon the back of theupright piece B are secured two guide-pieces ff,.between which is a slide-piece, g, having a screw-thread cut upon its upper edge.
The slide-piece g may b'e thrown up and down by a leven^ h, the` rear en'd of which 'is hinged at 1 to the piece B, while the other end plays inside of the `lower end of the hinged catch-piece-m.l
Catch-piece m is hinged at n, the upper end being thrown. ont by a spiral' spn'ng,'2, while the lower end is provided with a catch to4 slip under the lever h, when the latter is raised to throw-the slide-piece g into mesh with the thread on the shaft K.v
A stop-plate, L, is screwed` -uponthe end of the shaft K', to strike against the pin 3; for the purpose of forcingthe upper end of .catolx'lpiece m'in and the lower end out, to permit the lever 'It' tofall when the spindle H H has been run in farenough.
As soon as lever m falls, the vslide-piece y drops down, and the sliding table stops, although the screwshaft K may still be continued in motion.
The power to drive the spindle may be applied directly to the part H, bymeans of a b elt or band.
The front part H of the spindle is made in the forni in which the article is 'to be turned, which may be of any desired shape. Y
The front part of the spindle is slotted ont, as shown at 4, the slot extending down to near the cent-re ot' the hole -bored in the end of the spindle, for the reception of the metal blank 5, which is held in place by simply nicking or ling'oii" the end of the blank at one side, so that when it is run into the hole in the end of the spindle.the unfiled or unnicked side of the end ofthe blank will project in over thc flat part 6 of i the slot, as indicated in I sigure 5.
' By the abof'e arrangement, the blanks can be put in and taken out very quickly, while at the same time the necessity of a gripping-chuck, or other clampingdevice for holding the blanks in place during the operation of tapering and turning, is obviated.
' In theii'ont supporting-piece Gis ttedarest or eye, 7, tl'iehole in which is justA large enough to receive the blank to he turned or tapered.
The cutting-tool M isr secured, by means ofthe set- Sclew 8, in a s lot iu the upper end of the arm N,
which arm is fastened to the rock-shaft O, journalledl ,in the stands P l.
` The lower' end of the indicator-arm Q, is also secured to rock-shaft O, while its upper end is slotted to receive the jiction-roll 9, which runs in contact with thepattern-part H of the spindle when the machine is in motion.
The cutting -etool is drawn toward the blank by means of thev spring 10, and the same spring serves the'purpose of holdingthe friction-roll 9 against the spindle-part H by a yielding pressure, owing to the fact that its arm and the tool-arm are both secured to the same rock-shaft.
The operation is as follows:
Table D being runV back to its full extent, and a .blank being inserted in the end of the spindle, and
motion imparted to the latter, as before explained, the end of the lever h is raised,4 so as to throw' the slide-piece g into mesh with the screw K, when table D and spindle HH' will be moved forward, so as to pass, the blank 5 gradually through the eye 7, to be turned and` tapered as it passes" through, by means of the tool M, the form of the tapered or turned blank being of the saine shapeas the end H' ofthe Spindle. ,whatever that may be.
From the foregoingdescription, it will be seen that 'which said blank is held during the turning-operation,
my present machine is specially adapted for turning needle-blanks, and besides is not complicated orl liable to derangement of parts.
The pattern-part H of the spindle may be so madethat it can be readily detached from the main part H, to enable patterns of diiiierent styles to beused.
Having described my machine for cutting tapers,
That I lclaim therein as new, and of my invention, and desire to secure by Letters Patent, is-
1. In a machine for turning tapers, the employment, substantially as herein shown and described, of a divided spindle, the front or removable portion of which constitutes not only the pattern after which the blank is to be shaped, but also the support in as set forth.
the devices for holding the cutting-tool and directing its motions, substantially as herein descr bed, as shown in the accompanying drawings.
