FASTENING DEvIcE.

To all whom it may concern Be it known that I, LILLIAN K. ENGLE, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Fastening Device, of which. the following is a specification.

My-invention consists ofa fastener or fastening device for detachably connecting parts of materials, such as garments, which fastener is secured to the material Without stitching or other extraneous fastening and can be attached or detached to and from the material without the use of any special tool or mechanism.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

The annexed drawing and the following description set forth in detail one mechanical form embodying the invention, such detail construction being but one of various mechanical forms in which the principle of the invention may be used.

In said drawingsFigure 1 represents a plan view of one member or form of my novel fastener.

fastener illustrated inFig. 7. Fig. 10 represents a section of the fastener illustrated in Fig. 8.

Similar numerals of, reference corresponding parts in the figures.

Referring to the drawings, the reference numeral lindicates a body-portion, which is illustrated as formed from a flat bar or plate of sheet-metal or similar sheet-mate-' indicate rial such being the preferred material.

Pointed prongs, 2, are formed at the ends of the body-portion and extend inward at bothedges of said portion, pointing toward each other and having narrow slits between their' inner side edges and the edges of the bodyportion. The bar or body-portion disclosed inFigs. '1, 3 and 4, is formed with a swell, 3, at its middle, raised above the level of the Specification of Letters Patent.

Fig.2 represents a plan view of the cooperating part .of the fas view. The fastener is preferably formed'from,

sheet-metal, cut out and shaped by'stamping or similar. process, and, on account of the: f'simplicity of'its shape,'the' fastener canbe' Patented. June 8, 1915.

ends of the body and of the prongs. The form illustratedin Figs. 2, 5 and 6, has a tongue projecting laterally from the middle of one edge of the body-portion, to form' a hook, 4, one limb of which has an'inward hump5.

STATES PATENT orrro.

LILLIANIL ENGLE, 0F PHILADELEHIA, PENNSYLVANIA.

In Figs. 7 and 9, a clasp member, 6, is

shown as formed upon the face of the bodyportion, and in Figs. 8 and 1 0 is illustrated a tapering and flanged socket, 7, here shown in the middle 'of the body-portion, which socket can receive the clasp member 6 of the companion fastener to removably lock the parts together.

The prongs are inserted into the material to which the fastener is to be secured and the prongs penetrate the material, as seen in Fig. 3. 'The form of fastener, having the swell'in the body-portion is employed together with an opposite fastener having a hook, so that the latter can engage the swell and secure I the parts of the material to-' gether. 'The formof fasteners illustrated in Figs. 7 to 10is secured to the material in the same manner, as the previously described form, and the fasteners are detachably'connected as above described. The prongs projecting toward each other will secure the fastener against longitudinal movement and hold the same flatagai'nst the surface of the material, and the prongs, extending for the major portion of the entire length of the body-portion and forming the narrow slits between them and the edges of the bodyportion will clamp the fabric insuch slits,

and will prevent transverse 'movement of the fastener upon the surface of the fabric.

The prongs are substantially in the sameplane as the ends of the body, withtheir pointed ends suitably extending, if desired,

slightly below the body, or angularly, for ease of insertion into the material, wherebyv the fastener can be quickly and easily secured to the material and without any use of needle and thread or other tools or extra neous means. r

The fasteners occupy comparatively small space and admit of being secured within folds or ruffles of a garment to be out of made at very small-expense and in great quantities in comparatively short space of time. The body-portion can be shaped with varying forms of detachably interlocking fastening means, two forms being here disclosed. I

Other modes of applying the principle of my invention may be employed. for the mode herein explained. Change may therefore be made as regards the features thus disclosed, provided the principles of construction set forth, respectively, in the following claim are employed.

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

A fastening device, comprising a rigid body portion having a pair of integral prongs extending from each end thereof and longitudinally of the body portion and substantially in the same plane, the ends of the pairs of prongs pointing toward each other, said prongs being separated from the body portion with their inner edges substantially parallel with the edges of the body to form narrow slits in which the material is seated and gripped.
