4 Claims.

This invention relates to improvements in devices for securing clothing and other members together. While numerous devices have been proposed in this art for the attainment of that objective, such articles have generally been ob jectionable from the standpoint of being so complicated as to make it difficult to manufacture and use the same.

It is the object of this invention to provide a slide loop buckle which is of such construction as to make the application and use thereof to garments a matter of extreme simplicity. The device is so designed that the user may, in a minimum time, and by performing a minimum number of steps, secure together the desired parts of the garment in a simple and rapid manner.

The device is further designed to interlock the parts in use so that the slide loop buckle and parts secured together thereby will be precluded from accidental displacement, and, at the same time, may be manually disengaged in a rapid and facile manner, when so desired.

These and other advantageous objects, which will later appear, are acoompisl-led by the struc ture shown and illustrated in the accompanying drawings, in which:

Fig. 10- is a vertical, transverse sectional view, taken on line Ill-Ill of Fig. 9.

As shown in the drawings, the slide loop buckle of my invention comprises a rectangular frame member I I having spaced parallel side portions or channels I2 and I3 interconnected at their 2 inner ends by a transverse channel having a bottom defining a transverse reenforcing bar I4, said side portions and bar member (see Fig. 5) being provided with flanges I 5, I6 and I 6 respectively, projecting therefrom and defining the inner walls thereof. Plate I1 connects the inner walls of flanges I 6, I6 at the outer ends of the side portions I2 and I3 of the frame, said plate being angularly disposed relative to the plane defined by the said side portions and toward the free outer ends thereof and preferably terminating thereabove and therebelow. The plate I 1 thereby presents an inner edge I8 disposed at a plane beyond that of the flanges I6 and I6 and an outer edge I 9 in registry with the outer free ends 20 of the side portions I2 and I3 and disposed beyond the axial plane thereof. The plate I I thereby presents an angularly disposed portion in the axial plane of movement of the slide member 42 shown in Fig. 6 when the parts are assembled (see Figs. 4 and 10). The side portions I 2 and I3 of frame I] are provided with extended arm portions 2| and 22 directed toward each other and converging forwardly and united as atthe apex 23 to define a generally triangular web portion, thereby defining, with the bar I4, a triangular portion 24 unitary with the end of the frame member II opposite the plate IT. The side portions I2 and I3 and arms 2I and 22 of the frame II are preferably marginally flanged to define an outer wall 25 co -extensive with-said frame and directed at right angles to the axial plane of said side and arm members (see Fig. 5). The bar I4 is provided with a flange 2'6 directed at right angles thereto and in spaced parallel relation to the flange I5. The web portion 23 of the slide loop frame I I is provided with a medially recessed portion 21 extending almost to the outer wall 25 thereof for a purpose presently explained. The arm portions 2| and 22 are provided with inner flanged walls 28 and 29 (see Fig. 2) terminating at the recessed portion 21 of the web 23.

The slide bar member 42, as shown in Fig. 6, is of generally rectangular outline, and is provided with a medial aperture 0' defined by the inner flange Wall 32 of said bar. The bar is further provided with an outer free longitudinal edge 33 and with an angularly disposed wall 34 defining the other outer longitudinal edge thereof, said wall having

flat portions

38, 39 and 40 of substantially uniform height with the inner Wall 32 thereof. The outer longitudinal edge 34 of the slide bar is provided with serrations 35 intermediate the

fiat portions

38, 39 and it and protruding thereabove'. The marginal ends of the slide bar 3 are curled and directed inwardly as at 36 and 31 to define marginal bearings to slidably engage the side portions I2 and I3 of the frame II.

The flange [5 of the bar 14 and the flanges l6 and i6 of the side portions [2 and l3of the frame H define, with the plate I! connecting said flanges, an aperture A. The flange 26 of bar 14 defines, with the

flanged walls

28 and 29 of the arms 2! and 22, an aperture B. As will be apparent from an examination of Figs. 5 and 6, the frame II and the slide may be blanked out of unitary sheets of material, such as metal, and cut, bent and formed as unitary members, which by virtue of the structure thereof above described, have great rigidity and may be economically made by the use of conventional tools and dies as will .be apparent to those skilled in this art. The device may, of course, be manufactured from any other desired material and may be fabricated of a number of parts if so desired.

The slide member is mounted on frame H as shown in Fig. 1 so that, as shown in Fig. 4, the teeth 35 of the slide member are so disposed as to be in substantial axial alignment with the plate ll'rnedially.

The slide loop buckle of my invention is adapted for use in securing two members together, such as, for example, in securing a strap member to a bib member of a garment, as illustrated'in Figs. 7-10. In the first step as shown in Fig. 7, the strap member is passed over the plate I! of the frame II and under the slide bar, and threaded throughthe aperture 0 of the slide bar. The strap is next inserted intermediate the free outer longitudinal edge 33 of the slide bar and the bar M of the frame member H, to project the strap through the aperture A of the frame member and beneath the" triangular portion 24 thereof, as shown" in Fig. 8. The bib or other member to be secured to the strap has a button 4| secured thereto; in the thirdstep, the button Mis passed through the aperture B and recessed portion 21 of the web portion 23 of the frame, H (from the bottom thereof) as shown in Fig. 9. The bib is thus superimposed on the end portion of the strap as shown in Fig. and conceals the same as will be apparentfrom Fig. 9, so that the appearancepresented, in the use of structure of my invention, will be, as shown in Fig. 9, a neat and attractive one. 7

In addition to its function as a 'reenforcing bar, the bar l4 limits the extent of the aperture B and recessed portion 21 to also function as a locking bar or retaining means for the button 4|.

When the strap is inserted in the slide loop buckle as above described, the toothed wall 34 of the slide member will wedge the strap intermediate the slide bar and the plate ll (see Fig. 10) Any tendency of strap and bib to pull apart will simply serve to further lock the parts in the slide loop buckle against accidental displacement. At the same time, theparts may be readily manually displaced, whenso desired, by moving the slide member in a direction away from the plate IT.

The teeth 35 of the slide member are shown in the drawings as being arranged in two spaced groups (see Fig. 6), that arrangement being preferable in order to accommodate the stitched portions of the strap either at the flat

marginal portions

38 and 40 of the flange 34 (where the strap is provided with marginal stitching) or, where the stitching is along a medial axial line of the strap, the flat medial edge 39 of wall 34 of the 4 slide member intermediate the groups of teeth 35, will accommodate the same.

As, will be apparent from the foregoing description, the slide loop buckle of my invention may be used with equal eflicacy with strap members of various thicknesses. I have shown and described the use of my invention in the securing of a strap and bib member together; such showing is for the purpose of illustration only, and is not to be construed to limit the invention to such use as the device is obviously equally well adapted for use in securing other objects together.

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