and has particular reference to out linkconstructions. f

A popular cufflink arrangementl includes acen- Vs tral portion and a headwhichis selectively movable into two positions at right vangles to'each other.

prove the construction of this type of cuff link.

vobject of my invention to provide a construction which has a very strong and durable springmechaanism.

Itis an additional object f my'invepaon to l provide a simplified mounting for an ornamental fixed head at one end-of the cud. link central portion.

- With the above and other objects and advantageous features in view, my invention lconsists of a novel arrangement ofparts morel fullyvdisclosed in the detailed description iollowinginv conjunction with the accompanying drawing, and more specifically detlned in the claims lappended thereto. y

In the drawing,

Fig. 1 is a perspective viewof the novelcuif link, the movablehead being in one selective position;

.Fig 2 is a view similar to Fig. 1, the movable head being in its alternative selective position;

Fig. 3 is a detail ,enlarged view of the movable head, partly in section; Fig. 4 is asection, partly broken away, on the line 4--4 o! Fig. 3..- so Fig. 5 is a perspective view o! a modified link construction; l

Fig. 6 is a vertical section through the movable head thereof; f v l Fig. 7 is a perspective view of a further modified di) link construction;

Fig. 8 is a perspective detail of one spring end; Fig. 9 is an enlarged section on the line 8--9 of Fis. '7;

Fig. 10 is a perspective of the movable head cam;

Fig. 1l is a perspective of the ornament retainer nding; and

ig. 12 is a perspective detail view oi" the centrai portion iinding. j ons Referring to the drawing, the novel link I0 has a head Il fixed between side plates i2, I2, at one end thereof and a head i3 pivotally mounted between the side plates at the other end thereof.

The heads il, I3 are preferably of hollowcon 55 struction. the head ii being riveted to the side ,plates by through-pin u, and the head is having openings II and vbeing pivoted on .a through pin il of square cross-section. Each head preferably-has ian ornament `l1 at-'each end thereof,

having a backing plate il, the edges I9 of the head s end being swaged to lock the ornament in place. It is the principal object of my invention to im- Blocks 2Q having cylindrical shanks 2t and i generally square bases 22 are mounted in each end The movable head is preferably held in its sel0 lected position by spring means; it is a further of the movable head with the bases 22 contiguous to the through pin I8, anda coil spring 22 is it .seated in eachv end about the shank 2|, one eno. A contacting the plate it, and the other end engaging the base 22 to press vit towards the pin I6. I t is thus evident that the movable head may be swung, and as it swings, the blocl'rs 20 will be l `pressed outwardly by contact with the edges of the piny Il.' and will then be seated against the flat sides of thepin i6 by the springs, whereby the. movable head is resiliently held in two selective positions perpendicular to each other. If de- `20 sired, the pin Il may be made with a circular por# tion of narrow width seating in the circular open-1 ing i5; the platesl l2 may be joined by anv intef gral end 2l, see Fig. 1, to form a U shaped member, and the head I3, and the head Il if desired, 25

may have ornamental blocks 25 on' two sides thereof to complete'the design, as shown in Fig. 1.- `The'abov'e described construction utilizes spring mechanism which is entirely housed in the movable head; this arrangement depends for its $0 spring tension on the resilience ofthe coil springs.

It may be preferred to use other types of springs,

- which can be controlled in tension; such forms are disclosed in Figs. 5 to 12 inclusive.

- then move back to again engage the ends of the pin 32, thus selectively locking the movable head 45 parallel to the spring bars or at right angles thereto. The tension of the spring fingers may be controlled by the extent of the slot therebetween.

If desired, the spring mechanism may be made from a block metal, as indicated at 34 in Fig. 7, 50 the block having two spaced-

arms

35, 36 terminating in inwardly directed fingers 31 which as shown in Fig. 3 have two

V grooves

38, 39 at right angles to each other. A cam block of suitable form,v such as` for example illustrated in Fig. 10, may be l( positioned in the movable head 4|, and has spaced cross blocks 42 to engage the interior of the head 4| and hold the cam block against rotation, the cam 43 being between the vcross blocks and being square in section to provide cam edges 44. 'Ihe cam block is preferably of hollow stock to ensure lightness.

As shown in Fig. 9, the fingers 31 'enter into suitable openings 45 in the movable head, and

the grooves 38 contact the cam edges 44; when the A movable head is turned, the cam edges 44 force the fingers outwardly until the grooves 39 are free, when the ngers snap inwardly to removably lock the movable head in its other position with the grooves 39 engaging the cam edges 44. The length of the arms control the intensity of spring action.

A fixed head 46 is mounted on the solid end of the block 34; the ilxed head may be of any type, and soldered, riveted, or otherwise secured to the lock end. A preferred construction includes forming the block end with an upstanding lug 41, see Fig. 12, on which an ornament support cup 48, preferably of stamped sheet metal, having an opening 49 to receive the lug 41 may be mounted, the end of the lug being riveted down to lock the cup to the blo'ck end. A stone or other ornament 50 may then be seated in the cup, and retained in place by swaging or rolling the rim I therearound.

While I have described specific constructions of cuil links and of spring mechanism therefor, it is obvious that changes in the shape and appearance of the parts, and in their size anlg, material, may be made to suit the requirements", of different cuff link designs, without departing from the spirit and the scope of the invention as dened in the appended claims.

I claim:

1. In a cuff link, a body comprising spaced bars, a head positioned adjacent one end of said body, a hollow head pivotally mounted between said bars at the other end of said body, said hollow head having aligned openings in the sides thereof to receive the ends of said bars, and cam means in said head positioned in alignment with said pivot openings and engaging the ends of said bars to releasably lock said head in selected positions relative to said' bars.

2. In a cuff link, a body having spaced bars, a head positioned adjacent one end of said body, a

i movable head positioned at thel other end of said body and having openings at the sides thereof, said bars having their ends seated insaid openings, said ends having cross grooves, and a cam block in said head having cam edges adapted to selectively seat in said cross grooves.

3; In a cuff link, a body having spaced resilient bar members provided with pivot portions at one end of said body, a head secured to said body at the other end thereof, a movable head member pivotally mounted on said pivot portions for swinging movement between said bar members, and cooperating elements on said bar members and said movable head member comprising cruciform grooves and cooperating cam edge means selectively engageable upon swinging movement of said head member relative to said bar members to releasably retain said head member in selected position relative to said bar members.
