To @ZZ whom it may concern,.-

Be it known that I, LEWIS M. COOK,a citizen ot' the United States, residing at Neenah, in the county ofl/Vinnebago and State of Wisconsin,have invented a new and useful Im# provement in Snap-Hooks, of which the following is a specification. Y

My invention relates to an improvement in snap-hooks for general use upon different parts oil harnesses, and upon ropes, chains, and all places for which the use of snap-hooks are adapted; and the object of my improvement is to adapt the hook for engagement and disengagement with ease and without requiring the use of the individual ngers of the person using it, the snap-hook only requiring to be grasped in the hand and a forcible movement of the snap-hook made lengthwise of it and toward or from the part to be connected with it, whereby the improvement is particularly adapted for use in the dark or when the hand of the person using it is encurnbered with a glove or mitten. I attain these objects by means of the construction of the snap-hook which is shown in the accompanying drawings, in which- Figure l is a top view ot the snap-hook with the end broken. Fig. 2 is a side elevation thereof, the hook being complete. Fig. 3 is a side elevation, the central portion of the body of the snapdioolr being in section vertically upon the line o. a of Fig. l; and Fig. el is a like view of said central portion, showing a modification in its construction.

Similar figures of reference indicate like parts in the several views.

l indicates the body ot the snap-hook; 2, a loop for its connection with a strap or other part with which it may be desired to permanently attach it g 3, a loop at the opposite or hook end for the temporary connection with it of a ring, harness-bit, or other like part; ei, a slot which is formed in the body of the hook; 5, a three-armed spider which is pivoted for revolution within the slot; 6, a spring arranged within the slot; 6', a pin for holding said spring in position therein; 7, a removable piece for covering the opening to the slot upon the back or lower side of the snap-hook in Fig. 3; S 8', screw-holes in which screws may be inserted for connecting the piece 7 and spring 6 to the body of the hook.

shown in Fig. 3 is used, may be cast of a suitv able metal and titted together, the spring being bent ot the proper form for its suitable action upon the arms ofthe spider 5. In Fig. 3 the spring is provided with a hole corre spending in position with the hole S or 8', through which a screw may be inserted for holding the spring securely, the same screw also serving to secure one end ot the piece 7 to the body of the hook. The modication, Fig. a, being used, the spring is held within the pocket by means of a pin 6. the bottom of the slot and thereby forming a pocket, and locating the pocket directly under the end ot the hook l', it is more difcnlt for foreign substances to enter and clog the spring and spider than it would be it the slots were open and exposed on both sid es, as where they are located in the shank instead of the body ot' the device.

The spider is arranged for revolution within the slot upon the pivot 5 with two ot' its arms (excepting when a connection or disconnection is being made) arranged to bear upon the tree end of the spring, whereby the third arm ot the spider willextend upward and obstruct the passage between the body or swell of the hook which is around the spider and the end l ot the hook. As one of the arms ot' the yspider will always extend upward toward the end l', (excepting when the spider is being turned around upon its pivot for the entrance to the loop of some article or for its removal therefrom,) nothing can enter or leave said loop without the application of sufficient force to said arm to revolve the spider one notch-i'. e., until thisarm is turned down against the spring and another one takes its place. By making the spider with three similar arms and locating them equidistant from each other, as above described, it is free to rotate in either direction, and it is not necessary to insert it in any particular manner, as must be done with a two-armed spider, and after it has been inserted, as many attachments can be made with the one hook, as desired, by simply rotating the spider until all of the attachments have been made, as where it is desired to place two or more rings in the hook, and the attachments can be diseon By closingv IOO Vnected by simpiyzrotating the spider in the opposite direction, Which could not be doneV witha two-armed spider which oscillates upon its pivot instead of rotates;

By'providing a spring of the properk stitt ness the hook can beadapted for heavy or riight uses,` whereby a slight pull orpnsh upon f the hook will connect or disconnect the same from the ring or other article yWith which it ,and the siot around it from the entrance of snow, ice, dirtyffrc.,y and thereby providing for the free and easy working of thespider and f spring.

Having described my yini'Tentioini what j claim,A and desire to secure by Letters Patent,

l. A snap hook, the upper ySurface of the bodyo which is provided with a pocket, and

, the hook portion extends up over and formsr a cover for the same, a spring Within the pocket', and a spider pivotally secured Within the pocket above thespring, saidspider having'tnree similar arms equi-distant 'from each other and of the same length, two of said arme beingadapted to bear against thespring and the remaining one projects above the upper isurface of the ,body adjaeentto the hook, substantially as set forth; t

7 2'. A snap lioolgthe body ot' which is provided With a slot and thehook portion extends up over the slot and forms a cover for the same, a removable piece over the pocket f upon the opposite side of ,the tbody, aspiring r yWithin the slot, one end of which is located Y rbetween the body and one end of the removalolek piece, anda threearrned spider pivotally; secured Within the slot abovethe rfree end of the, spring, said arms being equidistant `from eachotherand of thesamie length,two arms of which are adapted to rest against the spring andthe other arm is adapted to project beryond the surface of the body adjacent the hook, substantially as set forth.y f f LEWIS M.
