Specification of Letters Patent.
Patented Dec. 31, 1907.
Application filed October 4, 1906- Serial No. 337,367.
To all whom "it may concern:
Be it known that I, GEORGE GoDLEY, a subject of the King of Great Britain, residing at Sarnia, in the county of Lambton, Province of Ontario, Canada, have invented certain new and useful Improvements in J ewelry-Clasps; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to jewelry clasps and it consists in the constructions, combinations and arrangements herein described and claimed.
The object of my invention is to provide an improved jewelry clasp in which the clasp members will be positively locked against accidental release by the action of strains tending to separate said members,- and in which the clasp can be readily released by relative movement of said members in a direction opposite to that tending to separate them.
In the accompanying drawing forming a part of this application: Figure 1 is a plan view, illustrating one embodiment of my invention with the two clasp members locked together; Fig. 2 is an elevation of the construction shown in Fig. 1 Fig. 3 is a sectional view on the line 3-3 of Fig. 1; Fig. 4 is an elevation of the outer clasp member; and tFig. 5 is an elevation of the inner clasp mem- Referring to the drawings, 1 indicates the outer clasp member provided with a cylindrical bore extending from one end thereof; the other end 2 carrying a ring 3 for securing a chain, or other desired article, thereto. Slots 4 are shown extending from the tubular bore, and provided with forward inclined Walls 5 and rearward inclined walls 12.
The inner clasp member comprises a cylindrical portion 6 carrying resilient arms 8, which are provided with heads 9. The heads are formed with inclined locking faces 10 for engagement with the inclined walls 5, and with inclined disengaging faces 11 for engagement with the inclined walls 12. It will thus be seen that the inner clasp member is adapted to be rotatably and slidably supported within the cylindrical bore of the outer member.
As shown especially in Fig. 3, the inclined faces 10 and 5 will act to positively lock the members against release under the action of strains tending to withdraw the inner member and support the clasp. It will be clear that a relative movement of the clasp members in a direction opposite to that of the strain normally maintained thereon in use will force the heads 9 inward from the slots 4 by engagement of the inclined faces 11 and 12. When the heads 9 have been thus disengaged from the slots, the clasp members can be readily separated by giving them a slight relative rotation in order to prevent the locking heads from rentering the slots during withdrawal of the inner clasp member.
Having thus described my invention, what I claim as new therein and desire to secure by Letters Patent is;
1. A clasp comprising an outer clasp member provided with a cylindrical bore extending from one end and with slots extending through the walls of said member at a point above the end of said bore, the forward and rear walls of said slots being inclined toward the forward, or open, end of said bore, an inner clasp member adapted to be rotatably and slidably supported Within said cylindrical bore, and heads projecting from said inner member, said heads provided with independent inclined faces for engagement, respectively, with the forward and rearward inclined walls of said slots, substantially as described.
2. A clasp comprising an outer clasp member provided with a cylindrical bore extending from one end and with slots extending through the walls of said member at a point above the end of said bore, the forward and rear walls of said slots being inclined toward the forward, or open, end of said bore, an inner clasp member adapted to be rotatably and slidably supported within said cylindrical bore, and resilient latches projecting from said inner member, said latches provided with independent inclined faces for engagement, respectively, with the forward and rearward inclined walls of said slots, substantially as described.
In witness whereof I have hereunto set my hand in the presence of two witnesses.
