Application filed Septeniberl, 1924. Serial No. 738,201.`

To all whomfit mag/ 00m ccm:

Belt known that l, ALBERT VERNER, a

citizen of the United States, and resident of- New` York, in the county `of New Yorkv and State of ,N ew York,l have inventedy certain new and useful Improvements in` ldethode` forplvlaking. Fine. Hair-Line Piercings,- of which `the:following is a specification.

rlhis Iinvention-'relates to improvements in the constructionfof crown or cap plates as used@ in` the manufacture ofk articles ofI provide a very narrowcircumambient space.

bet-weenuthe plate and frame,which maybe of onepiece construction.l

lVhen stamped of a singlepiece of metal itiV is foundfexceedingly, difficult, even to the point of impracticability, to produce such desirable narrow spaces, the limit of their width being substantially equivalent to the thickness of the stock in stamping operations, and in any case there must remain a plurality of thin and narrow connections between the plate and frame.

It is therefore one object of the present invention to provide means whereby the punched space between the plate and frame may safely equal the thickness of the metal or even exceed the same, and thereafter be reduced to the width desired.

A further aim is to shape the plate and frame coincidentally with narrowing the intervening space.

These and other allied objects are attained by the novel methods hereinafter described and illustrated in the accompanying drawing forming part of this disclosure, and in which Fig. 1 is a framentary perspective view of a conventional finger ring showing one application of the invention.

Fig. 2 is a transverse sectional view of a punch and die, and work part ready for operation in the die.

Fig. 3 is a similar view of the same parts when the punch has descended.

Fig. 4is another like view but showing a curved plate rather 'than flat.

Fig. 'is` a view similar to Fig. 3 but illustrating the back ofthe plate and its frame in the same plane.

Fig., 6 is a plan view of the plate and frame in unfinished blank form. e

Fig. 7 is a similar view of thesanie blank but showingthe space interjacent the plate and frame partially closed.`

Referringmore inf detail to the drawing, Figure 1 illust-rates an adaptation of the in.- vention, thebandvportiou 10 of a finger ring being widened at the settingor crown portion` 11, which may be of any preferred contour as will be understood.

Secured on this crown portion is a rim, or frame 12, in this case shown as hexagonal, and connected by inreaching bridges 13. is Va crown plate 14 containing jewels 15.

Referring now more particularlyto FiguresGand V7, the Aframe12` will be seen to be uniform thronghoutveach of its several side walls, and extendingiradially.inward from. the center-of" each sidewall are-bridge-likev connections 13, reduced in thickness and joining the crown plate 14 which may be imperforate or provided with an opening 16 to receive a gem or gems as indicated at 15.

The crown plate 14 is usually thicker than the frame, the underside or bottoms of both being level or the plate may be raised as preferred.

Surrounding the plate 14 is an open space 17 of uniform width, crossed by the deforme able bridges 13 and it is one of the obj ects to reduce the width of the space to less than the thickness of the frame as at 17.

This may be accomplished by the use of tools illustrated in Figures 2 to 5 inclusive and in these views 20 designates in general a die having a depression 21 the edges 22 of which are bevelled convergingly and adapted to receive the blank shown in Figure 6 in its upper portion.

rlhe bottom of the depression 21 is recessed as at 23, and this recess may be tlat as in Figures 2, 3 and 5, or curved as in Figure 4; a knock-out opening 24 passing through the dies to permit ejection of the plate.

rl`he punch 25 is shaped in conformity with the die and upon striking the plate, forces it down the inclined edges 22, thus closing the frame sides 12 and shortening the bridge connections 13, thereby reducing the width ot the space 17 equally and uniformly without distorting the plate 14:, which may be attened, curved or embossed iat desired at the one operation.

As all of the several sides of the frame or ring 12 are uniformly compressed it will be clear that the spaces 17 are equally narrowed and in extent equal to the angularity of the edges of the die.

t will be understood that instead of actually crimping or compressing the connecting bridges 13 the width ot' the piercings 17 may be reduced as viewed from the top "f or bottom by thrusting the crown plate 14 out of alinement with the frame 12 as the frame sides are closed in by the inclined edges 22 of the die, the crown plate and frame then being in different planes.

Likewise the piercings 17 may be narrowed by swaging the crown plate and rim portions or either of them to spread the metal.

From the foregoing it will be seen that a simple and novel process for constructing trame in a die having converging side walls and a bottom of desired configuration, whereby the frame is permanently contracted, the plate shaped to the die and the space between the frame and plate materially reduced.

2. The process of producing tine hair line piercings on articles or" jewelry which consists in first blanking out and piercing the article and then reducing the size of the piercing.

3. The process of producing iine hair line piercings on articles of jewelry which consists in lirst blanking out and piercing the article and then reducing the size of the piercing by spreading the metal bounding the piercing.

t. The process of making tine hair line piercings on ring tops which consists in first blanking out and piercing the top to produce a central portion surrounded by a frame with connecting strips or bridges therebetween and then shortening the bridges.

5. The process of making tine hair line piercings on ring tops which consists in first blanking out and piercing the top to produce a central portion surrounded by a frame with connecting strips or bridges therebetween and then forcing the central portion out of the plane of the 'frame portion.

Signed at New York, in the county of New York and State of New York this 27th day of August 1924.
