WIRE CLOTHES-PIN. l f

Specicatfon of Letters Patent.

Patented Dec.y 18, 1917.

Application med april 1o, 1915. serial No. 20,584.

` To all 'whom it may concern:

Be itknown that I, HANS HANsoN, a

l citizen of the United States, residing at Spring Valley, in the county of Pierce and State of Wisconsin, have invented certain new and useful Improvements in Wire Clothes-Pins, of which the following 1s a specification. L g My invention relates to an nnproved wlre clothes pin.

The primary object thereof 1s to provlde a device of thls character wherein the grip- 4 erate adjacent their lower ends, the outer jaws tending to resist the spreading of the inner jaws, and exerting a positive tension thereon when they are in engagement with a supporting structure; for attaining that element of absolute security necessary to the successful adoption of the device. I

The above and other objects which will become apparent are accomplished by such means as are shown in their preferred form in the accompanying drawings, described in the following specification, and more specically pointed out in the appended claim.

In the drawings wherein like numerals designate like parts throughout the several views;

Figure l is a perspective view of my inventlon showing the same in an operative posltion.

F ig, 2 is a side elevation thereof.

Fig. 3 is a fragmentary View showing a modified form.

In the construction of my improved clothes pin, a strand of resilient wire is bent to form two hairpin shaped members arranged one within the other, said strand being rst bent at a point 10 intermediate its ends, to form the inner member which comprises spaced apart gripping jaws. The lower terminals of the gripping jaws 11 flare as is clearly shown, to facilitate attachment and removal thereof.

At the lower terminals of the respective iared portions of the gripping jaws, the Wire strand is bent as at 12 to provide the .of the respective other jaws 13, extending substantially parallel with the jaws 11 yet 'projecting beyond the upper terminals thereof to provide a handle portion 14. The respective ends of the wire strand are cut at an angle similar 'to that designated by the numeral l5 and are adapted to be welded or otherwise secured together.

Attention is now called to the specific construction of the inner gripping jaws. The respective opposite jaws are provided with a series of curved portions 16 which are arranged as clearly shown in Fig. 2 to present a series of vertical openings. It is readily apparent that because of the gradual flare gripping jaws toward their lower ends, the openings formed by the curved portions 16 will be of varying diameters. The uppermost opening will have the smallest diameter, while the lower opening will be capable of receiving a structure of greater width.

As the pin is pushed downwardly over the structure A in Fig. 1, it will be recognized that the smaller openings will be brought over the rope portion B in succession until the opening ofa desired diameter is found. After the pin is arranged in an eiicient position as shown in Fig. 1 the co-action of the outer and inner jaws will become apparent. The lower ends of the gripping jaws will be normally held in engagement with the structure A by the tension exerted by the corresponding portion of the outer jaws, this not only preventing the accidental' dislodgment of the lpin but assuring a more eilieient and positive grip on the supporting structure.

In Figs. 1 and 2 I have illustrated the respective ends of the wire strand welded together to form a continuous handle 14 so that the pin may be easily and quickly manipulated and moved into or out of engagement with the supporting structure when desired. While this means of securing the terminals of Wire strand together has proven very efficient and inexpensive, in Fig. 3 I have shown a modified form which may bev used when occasion requires. In this case the respective terminals of the strand are curved to form engaging lips 17 the latter being shown in connected position. `This form of connecting the ends of the strand is also very eiiicient and I desire it to be understood that either of the constructions may bep employed without deviating from the scope oi my invention. The wire used. in the formation of my device is preferably that which is constructed of'a non-corrosive mafterial or which is coated with a non-corrosive material in order to eliminate oxidation and consequent rustin which would in time soil the clothes and c othes line in connection with which the same is used. l ln reducing my invention to practice l find that the form referred to herein'as the most, practical and referred embodiment, is the mest eiiicient; ut realizing that certain conditions will necessarily vary in concurrence with the adoption of my device, desire to emphasize the fact that various .minor changes in details of construction and proportion of parts ma. beresorted to when required without sacri cing any of the advantages of my invention as defined in the appended claim.

Having thus described my invention, what headset ll claim is new and desire to secure by, lle ters Patent is:

A clothes pin inthe form of a unitary structure composed of a piece of heavy spring wire bent to form two hairpin shaped members arranged one within the other with the legs of the members spaced apart from each other and from those of the other member, said members being disposed in the same plane, the inner member having its legs crimped throughout and the outer member extended at its apex or closed end beyond the closed end of the inner member to form a handle, the ends of the wire being united.

ln testimony whereof l affix my slgnature in presence of two witnesses.`
