FASTENING DEVICE.

Specification of Letters Patent.

Patented Dec. 28, 1909.

Application filed June 12. 1907. Serial No. 378.513.

l or similar fastening bands, and its object is to provide a fastening device which can be `easily and quickly manipulated and which will be economical in its construction.

The said invention consists of means hereinafter fully described and particularly set forth in the claim. y

The annexed drawing and the following description set forth in detail, certain mechanism embodying the invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention maybe applied.

y In said annexed drawings :--Figure l represents a perspective view of the two members of the fastening device embodying my invention, such igure'illustrating the two detached and separated. Fig. 2 represents a perspective View of said members in engagement, a portion of the stra or belt being shown as attached to the said members respectively. Fig. 3 represents a plan of said two members in normal engagement. Fig. 4 represents a lan of said two members in engagement, s lowing the eye-member folded back upon the 'hook-member. This latter figure further shows the position, in dotted lines, of the eye-member during the act of its insertion into the hook member., Fig. 5 represents a perspective view of the said two members illustrating the second position in which the leye-member may be caused to engage the hook-member. Fig. 6 represents a plan of said two members engaged as illustrated inFig. 5, the eye member being folded back upon the hook-member. Said Fig. 6 further illustrates, in dotted lines, the position of the eye-member during the act of its insertion intothe hook-member.

invention as illustrated in the drawing consists of the hook-member A andthe eyemember B. These two members lare respectively provided with eyes a and b through which the meeting ends of the strap or belt are inserted and secured in any well known manner, as illustrated in Fig. 2. The general form of ther hook-member is well known but I have provided, in addition, two laterally projecting lugs a. a. located upon opposite sides as illustrated in Fig. l. lugs serve a-purpose hereinafter described. The eye-member is provided with a slotb which is made of sufficient width to receive that portion of the hook-member intermediate of the lugs a and the extremity of the inserting portion of the hook. Adjacent to said slot b is an angularly projecting flange b2 which is made greater in width than that of the constricted portion a2 of the bight of the hook. That portion of the eye-member laterally adjacent to the slot b, that is the parts b3, is bent, so that when the two members-"are in engagement, the eye portions or shanks of the two members will lie substantially in .the same plane when they are in normal engagement, as shown'in Fig. 3.

In effecting the engagement of the two members, the eye-member B is placed in the position shown in dotted lines in Fig. 4, that is, with the front or outer edge of its flange first inserted into the bight of the hookmember, and vthen turned to the position illustrated in Fig. 3, in this position it is apparent that the two members are incapable of separation under ordinary conditions, the flange b2 being, as before stated, of greater width than the constricted portion a2 of the bight of the hook. The lugs a a prevent the two members from folding back upon Leach other completely, Fig. 4 illustrating the The movementto fold the two members back upon-each other, when occupying this last 'described position, will effect theengagement of the 'eye-member with the lugs a a considerably sooner than .it is effected in the rst described-position. The position ofthe two members when such last described en-.

These' llt) gagement is effected is illustrated in Fig. G in which it. is seen that considerably lessangularity between the tivo members exists, than existed in the first described position illustrated in Fig'. l.

By means of the. above described device I have provided a fastening device simple in construction, readily engaged and disengaged and which is capable of considerable latitude in the manner of its use.

Other modes of applying the principle of my invention may be employed, instead of the one explained, and change may be made as regards the mechanism herein disclosed, provided the means covered by the following claim be employed. l

I, therefore, particularly point outy and distinctly cl'aim as my invention In a fastening device, the combination with an eye member comprising a body portion havinr an eye opening and a flange ei;- tending substantially at right angles to the plane` of such body portion; of a. hook 'member adapted-to receive said flange `and provided with two outwardly projecting lugs adapted to engage that portion of the eye .memberl adjacent to the eye opening when thel fastening device is folded, the length of said flange being such that the folding movement of said two parts when the inner or rear edge of the flange is first inserted in the hook will be limited by the lugs and flange to a smaller range than such movement is limited When the front or outer edge of s'uch flange is first inserted.

Signed by me, this Sth day of June, 1907,

NVM. S. KATZENMEYER. Attested by- EL ROTHENBERG, LEN` A. Drnmu.
