PATENT SAMUEL F. SULLIVAN, OF PITTSBURG, PENNSYLVANIA.

HOOK AND EYE.

SPECIFICATION forming part of Letters Patent No. 645,434, dated March 13, 1900. Application filed July 22,1899. Serial No. 724,860. (Noinodel.)

To all whom it may concern/r Be it known that I, SAMUEL F. SULLIVAN,

a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Hooks and Eyes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it 'appertains to make and use the same.

This invention relates to certain new and useful improvements in hook-and-eye fastening devices, and has for its object to provide a hook-and-eye connection which when in position on a garment will not become disengaged through the movement of the body of the wearer and which will present a comparatively-iiat surface, also to provide for quick and convenient engagement of the members without undue strain and pull on the garment to which they are attached, in orderto overlap the hook on the engaging part of the eye member, as in the usual device. In my improved device the hook at the end of the tongue is very short and lies between the yielding side frames, so that by a slight pressure of the eye member upon the curved end of the hook the frame is pressed down and the eye passes into engagement with the hook, the movement of one member over the other being little more than the thickness of the wire strand of which the parts are formed. This feature of construction Vis quite important where a close and neat-fitting garment is to be fastened. The comparatively-flat surface presented by my fastening device is advantageous, since in consequence the garment may be passed through the wringer without injury to the device.

The invention further aims to provide a hook-and-eye fastening device that will be extremely simple in construction, strong, durable, effective in operation, and comparatively inexpensive to manufacture.

With the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts, to be hereinafter more particularly pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, in which-'- Figure 1 represents a top plan view of the hook member. neath plan view of the same. Fig. 3 represents a top plan lview showing the hook-andeye members in engagement. Fig. e represents a side view of the same. Fig. 5 represents a detail view showing the hook end of the tongue.

To construct the hook member, a single strand of wire or other material is employed, which is curved or looped at one end to form one of the sewing-loops a and is then extended 'lengthwise and turned laterally upon itselfthat is,doubled back to the second sewing-loop a', thereby forming the tongue b. The forward end of this double-strand tongue is bent upward from the back and then curved downward and inward with the tip or bill toward the back of the tonguev and within the frame, forming the hook c. The second or reverse strand of the tongue is curved at the rear to form the second sewing-loop a and is then extended longitudinally adjacent to the tongue, curved around the hook o, and then extended reversely parallel with the tongue to the first loop a, thus forming the yielding frame e e on the same plane with the tongue. The endof the side e is preferably extended below the end of the strand in the loop a for the reason that when such loop is sewed to a fabric it will cover and hold down such end of the side. The free end of the side e may be slightly curved or notched to receive the other free end of the strand, as indicated at Z. The eye member is likewise formed from one strand bent to form the eyelet j', which is shown square inthe drawings, though this may be any shape desired and with rear shoulders h. The two portions of the strand after forming the eyelet converge to form a shank f', and the ends are curved around the sh ank, forming sewing-loops f f.

The operation of my improved hook-andeye fastening device is as follows: ,The hookand-eye members being sewed to the garment by means of their loops, they may be easily and quickly engaged by inserting the front bar of the eye f between the hook c and the Fig. 2 represents an under- IOO yielding frame e e and by slight pressure push the frame downward so that the eye becomes engaged by the hook c. The parts being engaged the bar of the eye slides on the frame and is held by the tongue from displacement in the ordinary movement of the garment. If there is a strain tending to pull the parts of the garment transversely to the line of fastening devices, the yielding frame will be forced outward by pressure on the body, and thus hold the bar of the eye up against the hook, so that perfect connection of the members is maintained. In order to disengage the members, the 'eye member is given a diagonal movement inward and laterally, so that one side thereof or one of the rear shoulders h shall be pressed upon the yielding frame e e', thus permitting it to pass under the hook c and entirely out of engage-V ment with the hook member.

'It will be noted that the tongue l), having the hook c, remains comparatively rigid both during the operation of engaging and disengaging the members, while the frame of the hook member yields or springs sufficiently to permit the eye member to engage with the hook. The tongue being formed of two thicknesses or strands of wire, while the frame is formed of but la single thickness and is disconnected upon one side, the frame is more elastic or yielding than the tongue and is therefore more readily depressed when the eye member is inserted between the hook and the frame.

It is to be noted that the device can be constructed of any suitable material, so as to make the same practical for other uses than that herein shown. The construction and arrangement of the device as herein shown produce a comparatively flat surface which will permit the device to readily pass through the wringer-rolls without injurious results.

Various changes may be made in the details of construction without departing from the spirit and scope of my invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a hook-and-eye connection, a frame formed of but a single thickness of metal and which is disconnected or separated upon one side, and having a tongue that is formed of two thicknesses of material, so as to be more rigid than the frame, and which is provided with a hook upon its outer end, the frame being adapted to be depressed when the two parts are brought together to be connected, substantially as shown.

2. In a;V hook-and-eye fastening device the hook member comprising a tongue having a hook, and a surrounding frame, said tongue being composed of a double strand bent upward from the back and then curved downward and inward with the tip or bill toward the back of the tongue and within the frame,

said frame being composed of a single strand f extending on both sides and around the hook end of the tongue, being disconnected on one side back of the hook and serving as a support for the eye member to slide upon.

3. In a hook-and-eye fastening device, the hook member comprising a tongue having a hook, and a surrounding frame on the same plane, said tongue being composed of a double strand bent upward from the back and then curved downward and inward with the tip or bill toward the back of the tongue and within the frame, said frame being composed of a single strand extending continuously from one sewing-loop parallel with the tongue, around the hook end, to the other sewing-loop, thus serving as a support for the eye member to slide upon. l p

In testimony whereof I afiix my signature in presence of two witnesses.
