Letters Patent No. 107,561, dotted September 20, 1870.
IBEQRVEMENT IN MACHINES FOR TURNING THE HBADS 0F `iBOflhlS.
The Schedule referred to in these Letters Patent and making part of the same To all whoml 'it may concernY Be it known that I, WILBUR F. SWATHEL, of Mount Carmel, in the county of New Haven and State of Connecticut, have invented anew Improvement in Machine for Turning Bolt-Heads; and I do,
hereby declare the following, when taken in connection with theaccompanying drawing and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawing constitutes part of this specification, and represents in- Figure 1, aside view;
Figure 2, atop view; and in Figure 3, a longitudinal central section.
This invention relates. to an improvement in machines for turning the heads of oval-headed bolts, particularly that class known as carriage-bolts, the object being to smooth and true Athe edge, which, by the process of forging, is naturally left more or less irregular; and l The invention consists in a device for-holding the bolt, to which alongitudinal movement is given, so as to carry the bolt to the cutter, and the arrangement of a cutter upon a revolving cutter-head, through the center of which a spindle passes Yto bear against and center the bolt-head, so that the cutterl revolving will dress the required portion of the head,.and leave all heads of the same class of the same diameter.
A is the bed of the lnachine.
B, the cutter-head, arranged so as to revolve freely in bearings CC, and. caused to revolve by the appli- 4cation of power to the pulley D.
lIn the cutter-head a cutter, b, is' arranged, the cutting-edge, as seen in ig.3, the reverse of'that portion of the bolt-head which is tobe dressed.
Through the center of the cutter-head a spindle, E, passes, the outer end of which is formed,. as seen in tig. 3, to receive the bolt-head, and of less diameter than the bolt-head, so as to leave exposed that portion of the bolt-head vwhich is to be dressed. The
spindle ls forced forward by the operation of a spring, as seen in the drawing, or otherwise.
F is a slide, arranged in suitable guides', f, so as to have alongitndinal movement, which is imparted to it by a treadle, H, operating through a lever, L, as seen in iig. 3, so that, by the depression of the treadle H, the slide F is moved toward the cutter-head.
On the said slide a device, d, is arranged for supporting the bolt a.. For carriage or square-neck bolts itis only necessary that the said device be constructed to receive th'e square part of the bolt, as seen. in the drawing. v
The bolt is set into the holding device, as seen in fig.r 3, the cutters revolving; the operator moves forward the slide F, .carrying the bolt-head against the spindle E, which enters the head, that is, holds it in a central position, the spindle yieldingnntil the head is carriedin against the cutter, as denoted in broken lines, fig. 3, the cutter dressing off that portion ofthe head required to be removed, and, when the operator releases the slide, it is thrown back, removing the bolt from the cutter, the spindle thrown out, ready to receive a second bolt, and so on. J
It will be readily seen by those skilled in the art, that the bolt-heading device may be fixed, and alongitudinal movement given to the cntter-lnad to bring the cutter against the bolt, but, without hunting myself to either of these two arrangements, I prcteivhc movement of the slide as first described.
I claim aslmy invention- 7 In combination with the holdiig device for supporting the bolt, the revolving cutterhead,"provided with the cutter b and the spindle E, through its center, all constructed and operating in the manner' specied.
