CLIPPER KEEPER.

Application filed February 23, 1924. Serial No. 694%,522

To all ywhom 'it may concern.'

Be it known that I, FREDERIC H. RAUH, a citizen of the United States, residing at South Orange, Essex County, New Jersey, have invented-certain new and useful Improvements in Clipper' Keepers, of which the following is a specification.

My invention relates to keepers or locking means for keeping closed the members oi jawed tools, and the like, so as to prevent the jaws from springing apart or opening when the tools are not in use. And my improvements are directed to means whereby a simple and ehicient form of-spring keeper is provided, which will ei'iectually lock Athe tool in the closed position, and when swung out of locked position will itself be locked in a .iixed but detachable relation to the part of the tool which carries it.

I have illustrated and will describe the improvements as applied to a pair of orange clippers, but it is obvious that the principle can be/used for other cutters, jawed tools, and the like.

In the drawings Fig. l is an eleva-tion of a pair of clippers showing my improved clip in locked position thereon, the unlocked position of the clip being indicated by broken lines; Fig. 2 is a detail, on an enlarged scale, of the keeper and its supporting lug; Fig. 3 is a sectional view on the line 3 3 of Fig. 2, looking to the left; Fig. et is a detail of the supporting lug; Fig. 5 is a sectional view of the lug on the line 5-5 of Fig. 4L, looking to the lett; Fig. 6 is an edge view of the spring keeper, taken as looking to the lel't on Fig. 2; and Fig. 7 is a cross sectional View of the same, taken as looking down on the line 7 7 ot Fig. 6. Figs. 2 to 7 inclusive are on an enlarged scale as compared with Fig. l.

In all the iigures similar parts are designated by similar reference numerals.

A conventional pair of clippers is illustrated as provided with shanks l, 2 normally urged apart by a spring 3the shank l being provided with a keeper carrying lug 4l, while the shank 2 is provided with a keeper engaging hook 5.

The lug i is provided with two opposed euplike depressions 6 6; and it is also provided, preferably on one side, with groove like depressions 7, 8, disposed at an angle to each other.

The keeper or hasp 9 is preferably formed of a loop of' resilient sheet metal, from the body of which two lugs 10-10 are'struck inward, so that their free ends will n ormally fall within the sockets 6-6, into which they may be passed by springing the keeper over the lug 4. The keeper 9 also has a projection Il formed upon its inner side by pressing in the metal oit' the keeper, and this projection is adapted to register with the depressions 7 and 8 in the-lug il. as the keeper is swung around the lug, so as to retain the keeper in the positions shown by the full and the broken lines in Fig. l, as may be desirable,l the elasticity of the keeper 9 allowing the projection l1' to ride up out of the depressions when the keeper is forcibly swung-around in either direction, the lug snapping back into whichever of the depressions 7 and 8 with which it is brought into register.; When the keeper is swung into locking position with the hook 5, as shown -in Fig. l, it will be held against ordinary displacementby the projection ll registering in the depression 7 and when ,it is swung out of locking' position and into the positions shown by the broken lines in Fig. l, it will beheld in that position by vthe projection l1 registerk ing with the depression 8, and will offer no interference with the hook 5, or with the shank 2 of the cutter inthe ordinary use of the tool.

It should be .noted that the conforma-r tion of the lugs l010 of the keeper is such that the drag of the hook 5 againstl the keeper, when they vare in the position shown in F ig. l, will causethe thrust ot" the lugs toy be against the wall of the sockets 6-6 at an angle which will cause the lugs to grip the walls of the sockets and hang to the lug et, insteadof riding out ofthe socket, as might be the case if the lugs 10-10 were disposed at-right angles to the body oi' the keeper 9, or were bent rearwardly. In practice, it is found that this formation gives a very dependable grip to the keeper on the lug and eiiectually prevents its displacementby the ordinary expansive force of the spring 3.

The convenience and efficiency of my improved orm of clipper will be appreciated by those accustomed to the use of clippers, and like tools, wherein keepers of the ordinary loop style, or similar non-lockable types, are used. Keepers of the classes just lllf) l mentioned are objectionable -iii that they constitute loose or swinging elements attached to one shank of the tool and likely :to vcome in contact with the othersliank of,

the tool, or itsv appendages at an .improper time, perhaps catching the operators hand between them, or being caught by twigs .orf

Vcombination, with one of such elements, of liasp engaging means, and with t-he other of said elements of an integral carrying lug provided with opposed, lateral sockets, and a resilient hasp mounted on the lug and'pro- .vided with integralv projections constituting t means cooperating pivotally with the carrying` lugs sockets.
