ALLAN G. DALZELL, OF
APPARATUS FOR CORRUGATING PATENT QFFICE,
NEWPORT, KENTUCKY.
CORES- FOR WATCH-CROWNS.
'31 15i,IFICATION forming part of Letters Patent No. 329,285, dated October 2'7, 1885;
Application filed April 15, 1885. Serial No. 162,295
To all whom 52. may concern:
Be it known that l, ALLAN O. DALZELL, of
State of Kentucky, have invented certain new and useful Improvements in the Apparatus for Oorrugating Cores for WVatchGrowns, of which the following is a specification.
This invention appertains to the manufacture of crown-cores, and relates to the apparatus for corru gating the heads of watch-crown cores, and is intended as a continuation of the method of making watch-crown cores described and claimed in an application for patent filed simultaneously with this application, said application being for an improvement in the method of and apparatus for making watch-crown cores marked Case A, and signed April 1, 1885, to which reference may be had. In the application referred to the core was formed from a solid metallic blank, said core having a spheroidal head and a projecting core washer or stem, and by reference to said application it will be'hoticed that the core-head was corrugated upon the under side from a point flush with the circumference of the stem to a point central between the base and apex of the head, Where the corrugations terminated. It is necessary, as was pointed out in the specification of the application referred to, to extend these corrugations past the center of the head and over the upper side of the said core-head a short distance for the purpose of holding the corrugated crown cap or shell, which is subsequently drawn over and fitted to the corehead.
The object of this invention is, primarily, to extend the corrugations of the core-head past the center and over the upper side of the said'head by means of certain dies, and at one operation, as will be hereinafter pointed out.
My invention consists in the special construction of dies to accomplish this end, subsfantially as hereinafter described.
Figure 1 represents in longitudinal section a die having an opening with corrugated cutting-edges, and apunch to cutthecorrugations on the upper side of core-heads, the core being shownas resting in the corrugated opening and the punch in position to push the core through said opening to cut corrugations (No model.)
therein; Fig. 2, a side elevation of the same, the punch having descended and pushed the core through the die, the core being shown as corrugated a short distance upon its upper face and past the center; Fig. 3, a plan view of the cutting-die, showing the round corrugated edged opening; Fig. 4, an under side view of the punch, showing the concaved lower end; Fig; 5, a side elevation of the core, showing the corrugations; Fig. 6, an under side view of said core; and Fig. 7 representsacore before being operated upon, or with the corrugations extending only to the center of the head.
In the drawings, A represents the cuttingdie, the said die being constructed preferably .of chilled or hardened steel, and being of a shape bestadapted to fit into a die-box, which die-box (not shown) will also be of steel. The die A is provided with a central longitudinal opening, a, which opening extends entirely through the die from its upper to its lower face, said opening being at the upper face of the die of a diameter slightly less than-the diameter of the head of the'core to be corrugated, and has a corrugated cutting-edge, a, the said corrugations corresponding with and fitting the corrugations of the core-head at their upper or terminal point, as represented in Fig. 7 of the drawings, which corrugations terminate at the center of the core-head, leaving a central seam around thehead. The lower part of the opening, as shown at b b, is of greater diameter than the upper or cutting part, a, which permits the core to pass through the die without obstruction after the corrugations are cut. The core B, (represented in Fig. 7,) having a corrugated under side or corrugations from a point flush with the stem to the center between the apex and base, is placed stem downward in the corrugated opening a, or the opening having a corrugated cuttingedge, (the diameter of the opening between the cutting-points being equal, or nearly so, to the diameter of the head at the terminus of the indentations or radial grooves, and the greatest diameter of. the opening a or outer cutting-edge being equal, org-nearly so, to the outside diameter of theradial ribs at their terminus or at the center of" the head,) after 100 which the punch C, which has a concaved lower face,or a face corresponding to the shape of the head, and which is at its operating end of adiameter less than the diameter of the opening a,-
is allowed to descend to push the core th rough the opening, thereby cutting away portions of the metal and continuing the corrugations past the center and overa portion of the upper face of the core-head, as represented at D, Fig. 5. The punch G will be connected to the plunger or die-holder of the press in the usual manner, the die and punch being used with a die-press of any ordinary construction. By this construction of die I am enabled to corrugate the core-head past the center of the minor diameter by one operation, and trim off any burr or uneven edge which might have been formed during the process of forming the head and corrugating the under side. This operation of cutting or continuing the corrugations past the center prepares the core-head to receive the corrugated crown cap or shell, which is subsequently drawn over and fitted thereto, Whit h operation of fitting the crown-cap to the head of the core will form the subject of a separate application, marked Case 0.
Insomueh as the method of corrngating watch-crown cores may constitute patentable invention, I would reserve the right to make such method the subject-matter of a separate application.
I claim- 1. In an apparatus for cutting corrugations in the heads of watch-crown cores and similar articles, the die A, having the opening a, pro- 3 5 rifled with the corrugated cutting-edge a and the punch or equivalent to press a core through the central opening, substantially as described.
2. In an apparatus for corrugating the upper part of watch-crown core-heads, the die A, having the opening a,provided with the corrugated cutting-edge a, of a diameter slightly less than the major diameter of the core-head, in combination with the punch 0, having the coneaved lower end, said concavity being ofa shape to correspond to theshape of the upper face of the core-head, and of a diameter less than the diameter of the opening a, said opening a having a dischargeopening, I) b, communicating therewith, through which the core passes after being operated upon, substantially as and for the purpose described.
In witness whereof I have hereunto set my hand and seal, at Newport, Kentucky, this 1st day of April, A. .D. 1885.
