SPECIFICATION forming part of Letters Patent No. 486,641, dated November 22, 1892.

Application filed July 2, 1892. Serial No. 438,748. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN W. GR-ANTLAND, a citizen of the United States, residing at the city of Philadelphia, in the county of Phila delphia and State of Pennsylvania, have in- Vented certain new and useful Improvements in Hooks, of which the following is a specification.

My invention relates in general to hooks that are employed in connection with eyes for fastening garments and other like articles; and it relates more particularly to that class of such hooks which are provided with means for preventing the accidental detachment of the eyes therefrom and which are commonly designated safety-hooks.

The principal objects of my invention are, first, to provide a simple, durable, eflicient, and com paratively-inexpensive hook; second, to construct and arrange the parts of a hook for operation in such manner that the hook is self-contained, meaning by that term that the eye may be attached and detached with out causing any of the parts of the hook to project beyond the general outline thereof, and, third, to provide a safety-hook that is not rendered inoperative by the accidental bending of the point of the bill, which frequently occurs in practice.

My invention consists of the improvements hereinafter described and claimed.

The nature, scope, and characteristic features of the invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which- Figure l is a top or plan view of a hook, embodying features of my invention and illustrating the same in connection with an ordinary eye. Fig. 2 is a similar view of the under side of the hook; and Fig. 3 is a side elevation of the hook and eye illustrated in Figs-1 and 2, showing the bill provided upon the under side thereof with a rampart or projection, and also showing a tongue carried by the shank and adapted to co-operate with the rampart or projection.

In the drawings, a is a hook comprising a doubled wire, having the doubled portion thereof curved to form a bill a, provided with a downwardly-projecting rampart a and having the doubled portion thereof also curved to form eyes a for the reception of the thread, by means of which the hook is commonly attached to place. One extremity of the doubled wire after forming a threadeye extends forward and forms a straight tongue or latch a that is adapted to co-operate with the rampart or projection a in the manner hereinafter explained. In use the eye I) may be inserted beneath the point of the bill a and then drawn forward past the rampart or projection a into the position illustrated in the drawings. During this operation the tongue or latch a yields slightly in a downward direction, thus permittingthe eye I) to pass the rampart or projection a and then returns to place in contact with the projection or rampart a in order to prevent accidental detachment from the hook and eye. The eye I) may be readily detached from the hook whenever it becomes necessary or desirable so to do by the simple operation of pushing the eye I) in a reverse direction between the rampart or projection a and its compleinental latch or tongue a.

Among the many obvious advantages 'pos sessed by a hook constructed in the manner hereinabove described the following may be particularly mentioned: First, the tongue or latch a does not project beyond the general outline of the hook, even during the operation of inserting the eye I; therein, so that the hook is self-contained; second, the bill a may be bent upward or away from its shank of, as frequently occurs in practice, without interfering with or injuriously effecting the effi ciency of the devices for preventing accidental detachment of the eye, because the resiliency of the tongue or latch a causes the same to follow up and co-operate with the projection or rampart a in its new position; third, the doubled-wire bill a presents a smooth extremity that does not tend to cut or otherwise injure the article to which the hook is applied; and, fourth, the two wires forming the rampart or projection a are brought close together in the manner illustrated in Fig. 1 and form by reason of their cylindrical or approximately-cylindrical shape a concave seat, against which normally en gages the intermediate portion of the tongue upward and forward from the thread-eyes and having its free extremity working in the opening between the wires of the curved neck portion of the bill and having its intermediate portion normally engaging said seat, substantially as and for the purposes set forth.

In testimony whereof I have hereunto set my signature in thepresenceof two subscribing witnesses.

JOHN W. GRANTLAND.
