SPECIFICATION forming part of Letters Patent No. 355,144, dated December 28, 1886.
Application filed August 16, 1586.
To @ZZ wwm t may concern:
Be it known that I, ALLAN CAMERON DAL-` ZELL, of the city of Newport, county of Camp` bell, and State of Kentucky, have invented certain new and useful Improvements in Apparatus for Covering or Capping Vatch- Crown Cores, of which the following is a specication.
' This invention relates to apparatus for covering corrugated watch-crown cores with sheetmetal crown shells or caps, vand is virtually a continuation of the method of making watch crowns as described in three several applications heretofore filed by me, April 15 and April 27, 1885, and numbered, respectively, 162,294, 163,621, and 163,628, the object of the invention being to provide a simple apparatus to draw over and lit a `corrugated shell-like blank to a corrugated crown-core.
My invention consists in the construction and combination of certain fdies and devices to iit a corrugated sheet-metal .crown shell or cap to corrugate crown-cores, substantially as hereinafter described, and pointed out in the claims.
Figure 1 represents in central longitudinal section a set of dies for fitting crown-shells to crown-cores constructed in accordance with my invention, said figure showing a core in place inside of a shell and in `position to be acted upon; Fig. 2, aside elevation'ofthesame, partially in section, showing the shell as having been acted upon and iitted to the core; Fig# 3, a plan view of the lower die, dieholder, and bed; Fig. 4, a. plan viewof the movable collar which fits around the lower die; Fig. 5, an under side view of the upper or active die; Fig. 6, a side elevation of the crown-shell with the core resting therein preparatory to being covered thereby, a part of the shell being broken away; and Fig. 7 illustrates in side elevation the crown shell and cores after the shell has been operated upon to tit it to the core. f
As in the application above referred to, the dies and auxiliaries hereinafter described are and will preferably begused with a double-acting press of any ordinary or improved pattern.
In brief, the vapparatus consists, essentially, of the lower die, A, its die-holder B, bed C, upper die, D, movable collar E for the die A,
Serial No. 211,047. (No model.)
and springsF to bear against the under side of the collar to keep it normally elevated.
Before entering into-a description of the apparatus I desire to here state that the core,
G, to be covered, as described in the application hereinbefore referred to, is constructed in one piece, (see Fig. 6,) it having a head, g', with aseries of radiating corrugatesg?, formed 6o therein and extending from a point near the apex to a point considerably past its horizontal center, and having a stem, y, formed integral with said head.
The shell-H, which is to. cover the'core, is 65 somewhat cup-shaped, it being pressed up from a sheet-metal disk, as described in my former application No. 163,621, and being subsequently corrugated to correspond to the corrugates in the head of the core. 7o
The method of corrugating shells for covering cores being well known in the art, it is deemed unnecessary to enter into an explanation.
The lower die, A, which is constructed of 73 hardened steel, will preferably be somewhat conical in shape at its lower or base portion, as shown at a', and will be seatedin a conical opening in the die-holder B.
As illustrated, the die A is considerably 8c larger in its base than at its upper end, the upper portion being turned down to form a stem or shank, a, the upper end of which isl concaved and corrugated, as shown at @to form a matrix corresponding in shape to the shape of the corrugated shell to be pressed around the core beforedescribed. The said base portion a has formed upon it at its upper end an annular flange, at, to slightly overlap the die-holder B, said flange precluding all 9o possibility ofthe die Abecoming pressed downward too far and becoming tightly wedged in the holder B, and also acting as a guide for the collar E during its descent, said collar havingan annular groove, C', formed in its lower face, 95
corresponding substantially to the diameter of the flange a4, and forming a seat therefor.
The collar E, which encircles the shank a2 of the die A, has a vertical central opening extending entirely through the same, correrco lsponding substantially to the diameter' of shank a2 of the lower die, the said opening being enlarged at its upper end, as shown at 02 to form a guiding-seat for the shank of the upper die. This collar E is made movable upon the shank c2 of the lower die, and is pressed normally upward by means ot' the spiral springs F, which are seated in vertical openings f', formed in the die-holderB, there preferably being, as shown in Fig. 3, three of said springs to each dieholder, arranged radi; ally and equidistant relatively to each other, the object of said springs being to press the collar suiciently far above the level of the upper end of the lower die that the upper die Will engage with the opening C2 before acting upon the shell seated in the matrix of the lower die, and also that the inner walls ofthe central opening will retain the shell and core in a vertical position and aligned with the upper die.
The upper die,D,has a concaved corrugated matrix, d', at its lower end, to act upon the shell H and pressrit Varound the upper portion, g', of the head of the core, said matrix being of a shape corresponding to the shape of the,
'upperportiom y', of the head, and having a crown cores may embody patentable invention,
I would reserve the right to makeit the subjectmatter, in part or whole, of a separate application.
I claim.- l. In an apparatus for covering watchvcro'wn cores with crown-shells,a lower die to support the shell and core, having a coneaved corrugated matrix corresponding in shape to the shape of the shell to be pressed over the core, in combination with an upper die having a concaved corrugated matrix to engage the shell and press it around the core,substantially as described. 4
2. An apparatus for covering watch-crown cores with crown-shells, comprised of the dieholder B, lower die, A, having the corrugated matrix a3 formed/in its upper end,the movable collar E, engaging the upper end of the die A. and the upper die, D, having the matrix d and central opening, di, in its lower end, all constructed and arranged substantially as shown and described. m
8. In an apparatus for covering watch-crown cores with metallic crown-shellsthe combination of the die A, having the matrix a formed in its upper end, the die-holder B, having a series of vertical openings formed therein, as described, the collar E, movably secured to the upper end of said die A, and springs F, seated in the openings in the die-holder and acting against the under side of collar E to press it upward, substantially as and for the purpose described. V
4. The die A, having the tapered base por tion c', stem a2 of lesser diameter' than the base portion, and having the corrugated matrix a formed in its upper end, and the annular flange at, formed between the stem and the base portion, substantially as and for the purpose set forth.
In witness whereof I have hereunto set my hand and seal, atv Newport, Kentucky, this 1st day of April, A. D. 1885.
ALLAN CAMERON DALZELL.
