SNAP.
y Application filed .March 22,
Y This invention relates to improvements in snaps and has particular reference tosuch as may be employed for connecting a lead or leash with a dog collar or'harness,-one
object of the invention being to provide simple and etlici-ent means to prevent displacement of the spring which operates normallyto lclose the jaws of the device.
A further ob 'ect is to provide simple and l0 Veticient means to lock the relatively movable members of a snap of the type to which the invention relates. Y 'With these and other objects in view, the invention consists incertain novel features of construction and combinations of parts as hereinafter set forth andl pointed out in the claims.
In the accompanying drawings;-4 Figurel 1 is a view illustrating an embodiment of our invention.
Figure 2 is a longitudinal sectional view with the Vdevice closed and locked. e A
Figure 3 isa similar view showing thedevice unlocked and open, and f Figure 4 is a detail view.
The snap comprises twolevers 1 and 2 pivotally connected together at 3 and formed at their forward ends to provide jaws 4' which, when closed form an overlapping joint 5. z y j At their upper or rear ends, the levers 1 2 are provided respectively withV arms 6-'7, the arm 7 being provided with an elongated slot 8"through which the arm 6 passes and the latter is provided at its free end with a cross-head 9. A spring 10 is so cooperable with the levers 1-p-2 as to maintain the jaws of the device normally closed.
A cross-bar 11 extends across the slot 8 near V one end thereof and a tongue 12 on one end of the spring 10 engages over this` cross-bar in a manner to prevent longitudinal movement of the spring in one direction while longitudinal movement in the reverse direc-'k' Y tion is' prevented by the engagement of shoulders 13 on said spring withfthe lever 2. `The free end of the spring 10 engages in a i groove 111 inthe inner face lof the lever 1 and the sides wall of thisgioove will *pre K comprising p' tvvo` levers pivotally connected vent lateral displacementfof the spring.
