International Classification:

A44B 1100

US Classification:

24647, 24537, 24645

Abstract:

A jewelry clasp used to secure a piece of jewelry to an individual. The clasp includes a female part attached to one end of the piece of jewelry that has a latch pivotally mounted within a recess on the female part. The latch includes a hook at one end having an outer sloping surface. The clasp also includes a male part attached to the opposite end of the piece of jewelry and including a loop. The loop has a crossbar at its outer end which has an outer sloping wall. The outer wall of the crossbar and the outer surface of the hooks slope in similar directions, such that when the crossbar is pressed against the hook, the hook slides upwardly with respect to the crossbar, until the hook passes over the crossbar and drops through the center of the loop to engage the loop. The clasp also includes a sleeve slidably mounted to the male part that selectively covers the engagement of the male part and female part when the clasp is in the engaged position.

US Classification:

63 31, 63 3, 63 26, 63 38, 245741, 24DIG 31

Abstract:

A stringless connector for a strand of beads includes a two-piece interlocking assembly, each piece provided with an eyelet for connection to eyelets of connectors for adjacent beads. The eyelet of one member defines a pair of legs that are inserted into one end of the bore in a bead, one of the legs having locking tooth projecting toward the other leg. The other member has a straight shank extending into the bore from its eyelet, the end of the shank provided with a second locking tooth which enters the slot between the legs of the first member, overrides the tooth thereon and interlocks therewith.

Howard S. Cheng - Chicago IL, US

International Classification:

A44C017/02

US Classification:

63 291, 63 21, 63 23

Abstract:

A closed loop connector for jewelry includes a first U-shaped connector half formed from a flat strip of metal and a second U-shaped connector half formed from a piece of metal wire. The connector half formed form the flat strip of metal includes tubular cylindrical end portions. The second U-shaped connector half is formed from a piece of metal wire having headed end portions, one of the headed end portions being captured in one of the cylindrical end portions and held therein for rotation on the axis thereof. The other of the headed end portions is captured in the other cylindrical end portion by lateral movement through an open slot in response to resilient deflection of the edges of the end portion forming the slot. The metal strips forming one of the U-shaped connector halves may be formed from stampings of different configurations.

Abstract:

A flexible tree cutting saw is operable from ground level for cutting limbs from a tree. The flexible saw includes a flexible cutting chain, about two to three feet in length, with a rope attached to either end and handles attached to the ends of the ropes. A telescoping device with a hook at its top end is used to place the saw over the tree limb with the flexible cutting chain on the tree limb, and the hook is designed to effectively grab the raised handle and lower it towards the user. The user grabs the handle and applies downward pressure and a back and forth motion to saw the limb. The flexible tree cutting saw use a jeweler's style chain with a plurality of substantially planar cutting segments, preferably made from stamped sheet steel, which are either linked together directly or linked together using oval chain links. The cutting segments have two cutting edges and preferably have teeth facing in one direction for a majority of the cutting span of the cutting chain. The planar cutting segments are mounted or linked in the chain so that the cutting edges of one segment are substantially perpendicular in orientation with respect to the cutting edges of the adjacent planar cutting segments, when the chain hangs naturally.
