WIRE POINTING MACHINE. No. 341,558. Patented May 11 1886.
UNITED STATES PATENT OFFIC "WILLIAM H. DAYTON, OF TORRINGTON, CONNECTICUT.
WIRE-POINTlNG MACHINE.
QPEGIFICATION forming part of Letters Patent No. 341,558, dated May 11, 1886. Application filed November 2, 1835. Serial No.181,(i02. (No model.)
.T 0 all 2071,0712, it may 0071067721.
Be it known that I, \VILLIAM H. DAYTON, of Torrington, in the county of Litchfield and State of Connecticut, have invented an In1- provement in Machines for Making Needle- Blanks and other Articles, of which the following is a specification.
A wire has been pointed and needle-blanks have been formed by the compressing action of dies that are revolved by and with a shaft, and are acted upon by swinging toggle-blocks. A reference is hereby made to Letters Patent No. 52,493, granted February 6, 1866, to Hopson, Brooks and Manville,and to Letters Patent No. 58,730, granted October 9, 1866, to E. J. Manville. In wire-pointing machines of this general character a difficulty has been eXperi enced from the dies compressing the metal in certain directions only. For inst-nnce, in the first-named patent the compressing actions are ninety degrees apart, and in the last-named such compressing actions are sixty degrees apart; hence in both instances there is a tendency to consolidate the metal more in some radial lines than in others. I rectify this tendency and overcome the aforesaid difficulty by gradually revolving the head that holds the toggleblocks, in order that no two compressions shall be in exactly the same radial lines. Thereby the swaging action is much more uniform and the needle blank more perfect.
In the drawings, Figure l is a vertical longitudinal section showing the parts of my swaging apparatus, and Fig. 2 is a front ele vation.
The shaft a is provided with a transverse mortise at one end, into which is received the two sWaging-dies c 0. These are held in place by a cap-plate, f, and the extent to which the dies may be opened between each com pressing operation is determined by the pointed screws 13, passing through the cap-plate f into conical recesses in the dies 0 c, as in the said Patent No. 58,730; or any other suitable appliance may be made use of,having this object in View. The shaft a is tubular, so as to allow for the passage into it of the reduced needle-blank or other article that is being operated upon, and l this shaft a and the dies 0 c are revolved at the desired speed by a pulley, 0, or other suitable device. Around this shaft or there is a tubular journal. b, and this is supportedin a suitable head-stock, D. and upon the tubularjournal I) is the circular head-block I), having recesses for the reception of the toggle-blocks it and bearing-blocks m, against which the radial set screws Z act to adjust the operation of the toggleblocksas in the said Patent No. 52,493. At the back end of the tubular journal b there is a gear-wheel, s, and upon the head-stock a worm-pinion, t, is supported in contact with the wheel 8, and this worm-pinion tis revolved by suitable power applied to the pulley u, or in any suitable manner. It is now to be understood that the shalt a is revolved with rapidity, and carries with it the swaging-dies cc, and that the toggle-blocks 6 act upon such swaging-dies to press them toward each other, as in the aforesaid patents; but in consequence of the gradual revolution given to the headblock by the worm-pinion tand gear-wheel s the toggle blocks it are carried around with the head block, and hence they are constantly changing their position in relation to the piece of wire that is being operated upon, so that the compressing actions follow one another all the Way round the piece of wire operated upon,thns rendering such compressing actions more uniform and the work performed more perfect.
I claim as my invention The combination, with the revolving shaft and swaging-dies, of a head-block and the toggle blocks carried by the same, and mechanism, substantially as specified, for gradually revolving the head-block and changing the points at which the swaging operations take place, successively, upon the wire or article that is being reduced or pointed, substantially as specified.
Signed by me this 23d day of May, A. D. 1885.
\VILLlAll H. DAYTON.
