Application filed June 27, 1917; Serial No. 177,334.

To all whom it may concern:

Be it known that I, NoLIE DIMIGK, a citizen of the United States, residing at Black Rock, in the county of Polk and State of Oregon, have invented new and The lower edges of said walls of the chanuseful. Improvements in Snap-Hooks, of Bel are beveled off as at 15 to coniiplement which the following is a specification. shoulders 5 on the sides of the shank '5, Thi i ti l t to ap hooks, and and the lower end 16 of the solid portion 11 more especially to the locking devices for extends downwardly from the bevels 15 closing the throat of the hook; and the across the throat of the hook and across its object of the same is to improve the conbill, the lower face of this portion 16 being i ti f h a l kin d vi e so as provided w th a recess 17 to receive the tip to leave nothing projecting beyond the ex- 2 of the b1ll 1, and the Outer W ll 18 of terior of the hook or the guard, and to said recess engaging the rabbet 3 when the id means f l t hi g th t h and parts stand closed as lndicated in Fig. 1. 7o swinging the guard to open the throat of All parts thus far descrlbed may be'made the hook without taking the tension ofi of r m castings or drop forgings, possibly th l tt bored to form the cavity 7 and the holes These and other objects are accomplished for the plvot 13, as well as the holes in the by constructing the device in the manner mS of he clevls 1f the latter be emhereinafter more fully described and p y fl 1erefore' the Structure is ex l i d, d as Shown i th d a i g t remely slmple and economical in manu h i facture. WVithout any means whatever for Fi 1 i a id l ti f h t locklng the guard when it standsacross i ht h ll d th f t f thi d i ith the throat of the hook, such throat is closed so th parts l d thereby when the hook hangs as seen in 2 isa side elevation of the pposite 1, because the Welgllt Of 11116 SOllCl. side or rear id f thi d i ith th parts 11 of the guard is sufiicient to swing it into Open the positionhere shown and the tension of Fi 3 i a f m d i f th h k a load applied to the bend 1 of the hook detac d f th d, d Fig 4 i a does not lnterrupt. However, I prefer to lower end view of the guard shown as disp y the cking devices next to be deconnected and raised a little above the upscllbedper end of the shank of the hook illustrated A hole 20 S bored through the rear wall in Fig. 3 to illustrate their relative posiof the guard about Where Shown in ti and a hole 21 completely through both walls,

Mounted in the hole The hook proper comprises a hill 1 whose 20 1S cfltch 23 havmg a beveled p a tip 2 is rabbeted at its outer side as at 3, 1n the hole 21 i a P and (113- the numeral 4 designates the bend of the Posed 1n the groove 22 1S a bill 26 n ec h k, d 5 i it h k whose upper mg the rear ends of the catchand pin. {ion is reduced in thickness as at 6 and These three elements may 811 be formed id d i one id f ith a it 7 11 1tegrally,and when put in place the beveled constituting a keeper as described below, tip of the catch stands within the channel this face being beveled off as at 8 from the 12 0f the guard While the P P j cavity to the inner edge of the shank. The P 3 through tovthe other side as seen at guard 10 is substantially triangular in side 25 Through the P 13 aSSed it elevation, is solid at what might be called stop 1n the form of another pin perhaps its outer side 11 and channeled as at 12 at a split pin) 27, and around the pin 25 is its inner side to pass astride the reduced oiled a spring 28 whereof one end rests on portion 6 of the hook-shank, and through his S Op and the other end rests against the the walls of said channel and the upper inner face of the rear wall of the guard so portion of said reduced shank is passed a that the normal tendency of the spring is to pivot 13. This may be a bolt, and by prefhold the bar 26 seated within the groove 22,

the tip of the catch projecting into the channel to engage the cavity 7 as best seen in Fig. 5.

With the parts constructed as described and properly assembled, the guard is unlocked by pressing on the front end of the pin 25. This moves the entire device against the tension of the spring 28, and disengages the tip 24 of the catch 23 from the keeper or cavity 7 in the reduced portion 6 of the shank of the hook. Now the guard may be swung aside as seen in Fig. 2, and the ring or other element with which the hook is to be engaged can be passed over its tip 2 and dropped into its bend at. Thereafter the guard is swung back to position, or perhaps allowed to fall back to position by its own weight, when the beveled tip 2 of the catch rises up the bevel 8 of the reduced portion 6, and the spring 28 causes the tip to slide into the cavity or keeper 7 in a manner which will be clear. As the guard reaches its closed position, its recess 17 passes over the tip 2 of the bill, and the wall 18 falls into the rabbet 3 so that the extremity of the bill is now thoroughly inclosed and pro tected; and if the exterior configuration of the hook and the guard has received proper attention in the process of manufacture, there are now no projecting parts thereon against which extraneous objects might catch. Moreover, all exposed parts of the locking mechanism stand normally substantially flush with the face of the guard, and if said parts are accurately fitted to the holes and channel, little or no rain or snow can enter to interfere with the successful. ac tion of the device.

What is claimed as new is 1. In a snap hook, the combination with the hook having a cavity in one side face of its shank, and a pivot bolt through the upper end of the latter; of a guard channeled to embrace said shank and pivotally mounted on said bolt, a catch slidably mounted in a hole in one wall of the channeled portion of the guard and adapted to move on a line parallel with said pivot bolt to engage said cavity when the guard is closed against the tip of the hook, the body of the guard having a hole through it near said first-mentioned hole and a channel connecting the two holes, a spring-actuated push-pin in the last named hole, and a bar connecting said pin and said catch and lying normally in said channel.

In a snap hook, the combination with the hook comprising a shank, a bend, and a bill, one of said parts having a cavity in its side face; of a channeled guard embracing the shank of said hook, a main pivot connecting the hook and guard, the latter hav ing a recessed lower end adapted to engage the bill of the hook when the guard is closed, said guard having a hole opposite said cavity and a groove leading radially from said hole, a catch in the hole and a bar in. the groove, both movable parallel with the length of said main pivot, a spring connecting the remote end of said bar with the guard and normally projecting the tip of the catch, and a push-pin for moving said bar against the tension of the spring, for the purpose set forth.

in testimony whereof I aflix my signature.
