Abstract: A cuff link including a base, which has two parallel blocks at the top and a longitudinal top open chamber defined between the blocks, which blocks each having a pivot hole and a side opening communicated between the respective pivot hole and the top open chamber, a button, which has a shank, which has two pivot pins respectively inserted through the side openings on the blocks into the pivot holes thereof for permitting the button to be turned relative to the base between the fastening position and the unfastening position, and a spring plate inserted into the top open chamber to support the shank and to prevent the pivot pins from moving out of the pivot holes.

Abstract: A fastening device for securely and reliably joining parts of clothing, such as shirt collars, shirt cuffs, or the like. The fastening device is adapted to be inserted through a sturdy and preformed opening in the clothing, such as a buttonhole. The device incorporates a sturdy base member having a stem and a bar-like clothing engaging head which is biased by springs. The head pivots so as to grip the clothing parts to be joined, while the springs firmly position the head in a parallel orientation to the base member, with the parts of clothing to be joined captured therebetween. The springs also provide automatic pivoting of the head so that the device can be conveniently and easily used one-handedly. The device may be ornamentally decorated with distinctive and visually appealing insignia.

Abstract: A cuff link assembly includes an elongated stem member, an ornament member on one end of the stem member, a cross member and a fastening assembly pivotally securing the cross member on the opposite end of the stem member. The fastening assembly includes a pair of non circular cam structures on the stem member and a pair of cam plates having non circular cam sockets formed therein on the cross member, and the cam structures are received in the cam sockets for releaseably retaing the cross member in various different angular positive relative to the stem member.

Abstract: A button has a body and a retainer for securing the body to cloth. The retainer has a T-shaped member with the leg of the T-shaped member remote from the cross piece shaped to form a hollow cup-shaped resiliently expandable member, the rim of which is directed toward the cross piece. The body has a receptacle formed by a blind bore opening into a cup-shaped cross section similar to that of the resiliently expandable member. In operation the resiliently expandable member rim is contracted and the resiliently expandable member is pushed through the bore into the receptacle cup-shaped cross section whereupon the resiliently expandable member expands to hold the retainer in locked position with the body.
