Speccation of Letters Patent.

Application filed August 7, 1908.

Serial No. 447,360.

Io all 'whom t may concern:

Be it known that I, FRED M. SWARTZ, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Pins, of which the following is a specification.

My invention relates particularly to cuff, beauty, waist, and other pins for personal adornment, but particularly to the body joint and catch.

The objects of the invention are particularly strength, simplicity, cheapness, and a minimum of parts.

It has heretofore been impossible to form in one integral mass a solid pin body, ears, catch, and pivot member. In that class of pins which employ a base plate lateral ears have been cut from a thin sheet met-al blank and upwardly bent to form oints and catches, but this weakens the ears at the bars and catch at their lines of folding, and, when the ears are formed in from the margin of the blank, impairs the strength of the adjacent parts of the plate, besides necessitating the use of independent pivot pins.

To the end of overcoming the described disadvantages and attaining the enumerated objects, my invention consists in the novel construction and combination of parts hereinafter described, and illustrated in t-he accompanying drawings, wherein- Figure l is a perspective of a solid blank from which my pin body is formed. Fig. Q, a perspective view of the blank after the first cutting operation. Fig. 3, a side elevation of the same in the dies, the latter being shown in section and with parts partially broken away. Fig. 4, a section on line m o@ of Fig. 3. Figs. 5 and G, are sections on lines y y and e e respectively of Fig. 8, and Figs. 7 and 8, bottom plan and side elevations respectively of my complete pin body, with a pin tongue mounted therein.

Like reference characters indicate like parts throughout the views.

My pin body is formed as follows: In Fig. 2 is shown a block of metal of suitable form consisting of an oblong body, A, having upon its under face near one end, a transversely disposed vertical lug, B, and, near the other` end, a longitudinally disosed curved lug, C. Both lugs are some ldistance inwardly from the side edges of the body. In order to ornament the face of the body, and groove a portion of the lug, C, the described blank is placed upon a die, D, having in its upper face two cavities, E and F, to receive respectively the lugs, C and B.

The cavity, E, is curved at its base and pro- *f vided with a longitudinal rib, c. An upper die, G, is provided with an ornamental design in relief, H, upon its bottom face. Then the die, I-I, is powerfully depressed upon the body, A, of the blank an ornament is impressed upon its upper surface as at I, and the rib c forms a groove in a portion of the periphery of the lug, C, as shown at c', Fig. 6. The blank is then removed from the dies, and the lug, C, is longitudinally bored near its base forming an opening, C', as shown in Fig. 6, and producing a substantially cylindrical pivot bar, D. The lug, B, is then cut out by dies into the hook form shown in Fig. 5. Any usual or convenient form of pin tongue, J, may then be mounted upon the pivot bar,D, with its point adapted to engage in the hook, B. rPhe resulting pin, it will be observed, comprises lateral supports, C, integral with both the pivot rod or bearing, D', and the body, I. Also, that the catch, B, is in one piece with the body; and that the body, A, of the pin is a solid, intact block.

That I claim is:

l. In a pin of the type set-forth, a body formed of a block of metal having an in tegral catch, and an integral joint member comprising supports, said catch and supports being struck up from one side of tho body by displacing the metal by dies or the like without bending leaving the other side smooth and solid, said guard and joint member projecting at right angles from the rear face of the body.

Q. In a pin of the type setforth, a body formed with an integral catch and an integral joint member having' a pivot bar integral therewith, said catch and joint member projecting at a right angle from the rear face of the body.

3. In a pin of the type set forth, a body formed of a rigid unbendable block of metal having an integral catch and an integral joint member, said catch and joint member being composed of metal displaced from the body from one side thereof, leaving the other side smooth and solid. Y

4. As a new article of manufacture, a pin joint member comprising a base, supports integral with the base, :1nd u single individual pivotI bearing integral withi both supports and uniting the saine.

5. In a pin of the type Set forth, a body formed of a rigid unbendable block of metal having an integral catch, said catch being composed of metal displaced from the body from one side thereof, leaving the other side smooth and Solid.

G. In a pin of the type set forth, a body formed of a rigid unbendable block of metal FRED M. SWARTZ.
