IMPROVEMENT IN MACHINES FOR FORMING TEMPLE-TEETH.
Specification forming part of Letters Patent No. 150,828, dated May 12, 1874; application filed February 24, 1874.
T0166 whom it may concern: 7
Be it known that I, NATHAN, CHAPMAN, of Hopedale, county of Worcester and State of Massachusetts, have invented an Improved Machine for the Formation of Temple Teeth or Points; and I do hereby declare the following to bea full, clear, and exact description thereof, reference -being had to the accompanying, drawings forming a part of this specification.
Figure 1 is a top view of my machine. Fig; 2 is a perspective view of the side and top. Fig; 3 is an end View, and Fig. 4 is a longitudinal section, of the wire-holder.
My invention relates to improvements in machines for pointing wires for temple-teeth 5 a and consists, first, in the employment of an abrading surface, across the face of which a frame carrying the temple-teeth is made to' able for the purpose, fastened securely to the shaft 1, said shaft having at or near its outer end the pulley D, adjusted to the shaft by any of the well-known devices. The shaft Z is journaled to a movable frame, m, having a' projecting, tenon, f, at right angles with its lower surface, said tenon passing through the mortise or aperture g, formed through the supporting-frame. Passing through the side of the mortise or aperture 9, and bearing against the tenon f, is the screw h, for securing the frame m at any desired elevation. In a parallel line with the axis of the emery-wheel A, and placed above the center of said wheel, is the sliding frame 0, having the wire-holding device B journaled in "a suitable manner at right angles with the emery-wheel A. A small spur-gear, L, is attached to the periphery of the wire-holderB, said gear working in the rack m, firmly secured to the supporting-frame.
The wire-holder is also provided with a slid in g collar, z", having its interior slotted or grooved to embrace the movable tapering jaws k k. The spring j, coiled around the periphcry of the wire-holder B, between the spur-gear L and the collar i, forces this collar against the projecting tapering jaws la la, pressing them against the wire 0, and thus preventing any motion of the wire other than that communicated by the wire-holder B. J ournaled to the supporting-frame, at a suitable distance from v and parallel to the wire-holder B, is the shaft E, having the pulley F and the wheels H and G. Projecting from the wheel H at right angles, and the requisite distance from the center to secure the desired motion, is the pin 2, and projecting at right angles from the wheel G is the pin ac. Connecting the pin m and sliding frame 0 is the arm I; and placed below the sliding frame, parallel to the wireholder B, and secured to the supporting-frame by suitable journal-boxes, is the rock-shaft J, having at its outer end the right-angled arm 0, and at or near the mid-length the projecting arm m. 'With the inner end of shaft J the arm n is connected, moving in suitable slides secured to the supporting-frame, and between said frame and the end of emery-wheel A is the knife'N, having a beveled edge, and its outer side provided with the pin 0. Parallel to the wire-holder B, and at right angles with the face of the emery-wheel A, is the horizontal sliding bar I), having at its outer end the upwardly-projecting arm 60, with its gripingjaws a a Projecting downward from the bar I), at a suitable distance from arm a is the arm 01. Extending from the pin 2 on the wheel H to the arm 0 on the rock-shaft J is the arm K. The gripingjaws a a are oper- .ated by the action of the pin 3 projecting from the supporting-frame and depressing the end of the lever a, forming the lower gripingjaw a when the sliding bar I) is moved toward the emery-wheel by the action of the arm m on the rock-shaft J. Any number of wire-holders may be employed.
The operation of my invention is as follows: The collar 11 on the wire-holder B being pressed against the spring j releases the tapering jaws k 70, and allows a suitable length of wire, 0
to be inserted in the wire -holder 13. The pressure being removed from the collar 13, the spring j forces the collar i against the tapering jaws L It, pressing them firmly against the wire 0. The emery-wheel A having a rapid rotary motion imparted by a suitable belt or cord, the shaft E is set in motion, and the sliding frame 0, carrying the wire-holder B, is carried across the face of the emery-wheel A. The wire-holder B is rotated. upon its axis while passing the emery-wheel A by the ac-- tion of the spur-gear L and rack m, and a true cone of any desired angle is thus formed on the end of the wire 0. hen the sliding rest has moved the requisite distance past the emery-wheel A, the sliding shaft 1), oarryin g the griping-jaws a? a, is moved forward by the action of the arm m, and the jaws a a grasping the wire 0, force it through the wireholder the required distance, when the knife N is forced upward, by the arm a acting upon the pin 0, against the projecting point P, and the finished tooth or pin drops into a suitable receptacle; and the sliding frame and wireholder pass back by the face of the emerywheel, when the same process is repeated, 6X- cept inserting the wire. S (see Fig. 2) is a spring, preferably of a coiled or spiral form, connecting the barb and one of the outer standards of the machine, the tension of which operates to move the bar I) outwardly or away from the emery-wheel A.
Among the advantages to be derived from the use of this invention are, first, dispensing with skilled, costly labor, and, at the same time, performing better work. None but experts can grind the temple-teeth to the required accuracy, and no expert can compete with the invention described in accuracy or speed. After the temple-teeth are ground and finished they are to be inserted in the wooden roll, and
for this purpose a steel die is used; and to force the teeth thus formed into the roll without dulling the perfect point requires the nicest precision. By my process the points are all formed alike, having the same angle, and all fitting into the steel die with the greatest preoision; and, in addition to this, the saving of costly material is of itself an item of great importance; the inability of a hand workman to properly handle a short piece of the wire; then the length of tooth desired can be produced with accuracy, so that when the teeth are forced to their places in the roll the finished temple presents an even, true succession of points.
Having thus described my device, what I wish to claim as new and of my invention is 1. The reciprocating frame 0, carrying the wire-holder B, in combination with the pinion L, rack M, and abrading-wheel A, substanlsially as described, and for the purpose set orth.
2. The wire-holder 13, provided with the longitudinal opening, as described, and surrounded by the coiled spring in combina tion with the sliding collar 2' and wedges k k, for the purpose of clamping the wire, substantially as described.
3. The combination and arrangement, as described, of the adjustable abrading-wheel,
the reciprocating frame, hollow rotating wireholder, griping and feeding jaws, and cutter, substantially as described, and for the purposes set forth.
In testimouy of this invention I hereunto set my hand. 1
NATHAN CHAPMAN.
