Description

E. J. SWEDLUND.

CLASP. APPLICATION FILED NOV. 7. 1916. Patented July 1o, 191'?.

ERICK J. SWEDLUND, 0F WILLISTON, NORTH DAKOTA.

CLASP.

Application filed November 7, 1916.

To allee/bom t may concern.'

Be it known that I, Enron J. SWEDLUND, a citizen of the United States, residing at ldilliston, in the county of lVilliams and State of North Dakota, have invented certain new and useful Improvements in Clasps, of which the following is a specification.

his invention relates to certain new and useful improvements in clasps and it has for its objects among others to provide a simple and cheap construction and yet one that will be positive and durable in its aetion and cheap of manufacture. It is composed of few parts, those compactly arranged, readily held against separation under normal conditions and not liable to injury or breakage in use.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which- Figure l is a substantially central longi tudinal section through a clasp embodying my present invention with the parts in locked position.

Fig. 2 is a similar view showing the parts in position for removal of the locking member.

Fig. 3 is a view similar to Fig. l, showing a modified form of construction.

Like numerals of reference indicate like parts in the different views.

Referring to 'the drawings,

1 designates an outside shell or tube which, however, may be of any desired form in cross section open at one end and at the other end having an opening 2 surrounded by an inwardly extended flange 3, the inner walls of which are inwardly tapered, as at i see Figs. l and 2. This flange forms an inner shoulder 5 for a purpose which will soon be made apparent.

6 is the inner member or tube conforming substantially in cross section to the outer member 1 and adapted to slide therein within predetermined limits. It is open at its inner end, as seen in Fig. l, its outer end being closed and preferably provided Specification of Letters Patent.

Patented July i0, 191i?.

Serial No. 129,996.

with a loop or ring 7 for attachment to the end of a chain or necklace or the like.

8 is the locking member of substantially V-shape having one end bent to form a ring or loop 9, as seen in Figs. l and 2, the other end being free and curved away from the member or arm thereof which termina-tes in the loop or ring 9 to form a spring locking point l0.

rIhe members l and 6 are arranged, as above described, to have sliding movement the one within the other, but, as shown in Fig. l, the outer tube l is provided with an annular inwardly extended rib or depression ll and the inner tube 6 is provided with a longitudinally extended groove or depression l2 'within which the depression l1 is received so as to permit sliding movement, to the extent necessary to permit of the successful operation of the device, but preventing entire separation of the tubes or members 1 and 6.

In Fig. 8 I have shown a device similar to that above described in all respects except as to the means for preventing separation of the members l and G, yet permitting the necessary longitudinal sliding movement thereof. In this form I provide a screw 13 in the member l engaging in the longitudinal slot 14 in the inner member 6, for a similar purpose.

In both forms the locking member S has a bend l5 adjacent its junction with the ring or loop 9 which engages the inner wall of the iange 3 for the purpose of assisting in pushing the inside tube G outward when the locking member is inserted as well as to take the strain and prevent injury to the locking member in use.

rllhe parts, as shown in Fig. l, are in their locked position. To unlock the clasp, the inner member 6 is pushed inward, that is in the direction of the arrow in Fig. l, until the inner end thereof riding up the incline 16 of the shorter arm of the locking member 8, forces the same toward the other arm of said member, as seen in Fig. 2, bringing the point lO inward beyond the shoulder 5 in alinement with the bevel wall fl of the openin g 2, when'the locking member may be readily withdrawn, as will be readily understood upon reference to Fig. 2. To lock the parts, it is only necessary to insert the lock- I ing member 8 through the openino 2 until it pushes the inner member 6 slightly outward when the spring arm of the locking member is thrown outward into the position seen in Fig. l where it engages the shoulderI 6 to avoid all attempts to disengage the parts.

Modifications in details may be resorted to without departing from the spirit of the invention or sacriiicing any of its advantages.

lVhat is claimed as new is l. A clasp comprising inner and outer members telescopically arranged and a locking member comprising a spring arm moya ble independently7 of said members and controlled by the engagement of the inner member to bring it into unlocking position.

2. A clasp comprising inner and outer members telescopically arranged, means for limiting the relative movement of said members and a looking member embodying a spring arm movable independently of said members and insertible through an opening in the outer member and engageable by the inner member to unlock the parts.

3. A clasp comprising inner and outer members telescopically arranged, coperat-4 ing means on said members to limit their longitudinal movement, and a spring locking member movable independently of said members and having a curved terminal for engagement with the inner face of the end wall of the outer member to prevent separation of the parts.

t. A clasp comprising 'inner and outer members telescopically arranged, coperating means on said members to limit their longitudinal movement, and a spring locking member movable independently of said members and having a curved terminal for engagement with the inner face of the end wall of the outer member to prevent separation of the parts, the opening in the end wall of the outer member being inwardly beveled.

5. A clasp comprising inner and outer members telescopically arranged, coperating means on said members to limit their longitudinal movement, and a spring locking member movable independently of said members and having a Curved terminal for engagement with the inner face of the end wall of the outer member to prevent separation of the parts, the opening in the end wall of the outer member being inwardly beveled and the locking member having a loop and a bend adjacent thereto for cooperation with said beveled Wall.

In testimony whereof I aflix my signature in the presence of tWo Witnesses.
