SNAP nook.

Application filed August 19, 1925. Serial No. 51,204.

This invention relates to improvements'in snap hooks, the oeneral object of the invention being to provide spring means for holding the movable part of the hook in closed position and means actuated by the spring means tor preventing the movable part from being; moved to open position until such movable part is manually operated.

This invention also consists in cert-ain other Jfeatures o't construction and in the combination and arrangement of the several parts. to be hereinafter fully described, illustrated iu the accompanying drawings and specifically pointed out in the appended claims.

In describingmy invention in detail, reference will be had yto the accompanying` drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a side view of the improved hook.

Figure 2 is an edge View thereof.

Figure 3 is an enlarged sectional detail 55 view.

Figure 4 is a similar view, but showing the hook in open position.

Figure 5 is a section on line 5-5 of Figure 3.

Figure 6 is are 2.

lu these views, l indicates the body part ot the hook, which is made as usual, and f2 indicates the movable part which is slidably arranged in the hollow stem l of the body. In carrying out my invention, I make this movable part 2 ot two parts 3, each of which has a lateral projection 4 thereon which is provided with a rounded head 4 and a rib 7 which terms the shoulder 8 adjacent the inner end ot each part. The inner end of each part tapers so that the Said ends form a seat for a ball 9 which is pressed thereon by a spring l0, the ball and spring being arranged in the hollow stem l. This stem is provided with the oppositely arranged slots ll for receiving the projections 4 and the ribs T. Y

From the foregoing, it will be seen that a section on line 6-6 ot' Fig the pressure of the spring l0 on the ball 9 will tend to move the parts 3 outwardly to closed position with their outer ends engaging the end of the hook part and this pressure will also force the inner portions of the two parts outwardly so that the ribs will engage the slots with their shoulders 8 adjacent the closed ends of the slots, so that said shoulders will act as stops for preventing in'- ward movement ot' the parts. Thus the movable member 2 will be. locked when in closed position. llfhen the hook is to be opened, the parts 4 are pressed upon by the fingers ot the operator, which will move t-he members 3 towards each other, forcing,` the ball downwardly and placing` the ribs within the bore of the stem. Then the members 3 are pushed inwardly or downwardly to slide the lower part of part 2 within the stem so as to open the hook. This will compress the spring l0, as shown in F igure 4. As soon as the fingers are removed from the parts 4', the spring 10 will project the parts forwardly and outwardly to the position shown in Figure 3. Thus I have provided spring means for normally holding` the hook in closed position and also in locked position so that it will be impossible to open the hook unless the two parts 3 are pressed together and then downwardly by manual force.

It is thought from the foregoing description that the advantages and novel fea tures of my'invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope ot the appended claims.

IVhat I claim is 1. A snap hook comprising a hollow stem formed with longitudinal slots at opposite sides thereof` a two-piecemovable part in the stem each piece having a lateral projection with a head thereon and a rib arranged below they head, said ribs movable in said slots and having shoulders engaging` the inner ends of the slots, a spring pressed spherical member normally engaging the inner ends of the pieces of the movable member for normally urging them outwardly into a closed and locking position.

2. A snap hook, comprising a hollow stem, a movable part arranged therein and composed of two portions, each port-ion having a lateral projection with a head thereon and a rib, the Stem beingslotted to receive the projections and ribs, a spherical member engaging the inner ends of the two portions and a spring engaging the spherical member for forcing the parts outwardly into closed and locking position.

In testimony whereof I afix my signature.

ARTHUR E. BERGQUIST.
