` Application led June 5, 1912. Serial No.` 701,730.

Patented Jan. 7,1913.

To all whom z't'may concern.'

Be it known that I, LoUIs A. NEGRAvAL, a

v citizen of the United States, residing. at

Jersey City, in the county of Hudson and State'of New Jersey, have invented a certain new and useful Improvement in .Slides for Garment- Supporters, of which the following is a specification. i

' The invention p relates to friction slides used in connection with strips or tapes of webbing in adjustable garters and analogous articles, and the object of the invention is to provide a slide of this class which will'perform its frictional holding functions successfully, may be easily and economically manufactured from thin sheet metal with but little waste, and carries means formed integrally therewith for grasping the end of the webbing reliably.

The invention consists in certain novel features and details of constructionby whichl the above objects are attained, to be hereinafter described.

,The accompanying drawings form a part of this specification and show an approved form of thev invention.

Figure 1 is a face view of the slide fin position upon a strip of webbing, and showing the outer face. Fig. 2 is a similar view of the slide alone. Fig. 3 is a corresponding view of the inner face, showing the engaged end of the webbing. Fig. et is a face view of the slide as it appears at a stage of manufacture prior to bending to form-the gripping teeth and jaw. Fig. 5 is a transverse section 'of the slide on a larger scale, showing the position of the teeth and jaw after bending but before the insertion of the webbing-end. Fig. Q is a similar view showing the webbing-end 1n place and gripped by the teeth and jaw.

Similar letters of reference indicate the same parts in all thefigures.

The slide is shown as a thin metalframe of rectangular form having a central bar `A and an opening or slot B C on each side thereof, through which the tape or elastic webbing is passed as usual, but it will be understood that the contour of theslide is not essential and may be widely varied.

A portion of the metal is removed to form the slot` C, the dies being arranged to produce a smooth straight cut forming the inner l edge of the outer bar A2 and a serrated cut on the adjacent edge of the central bar A, thus providing a series of sharp teeth D along the latter.

The slot B "s produced without removing the metal; a smooth cut is ma'de'to form the inner edge of the outer bar A1 and is continued a short distance inward at each end,

the inclosed material forming a ap, as indicated in Fig. 4, ready to be bent out of the plane of the bars to form the. jaw F. y

By the same dies thatformed the teeth D, or at a subsequent operation, the teeth are bent upward and backward toet-and at an angle slightly acute to the plane of the bars, and the jaw F is similarly folded over on the same face to bring its free edge in proximity lto the line of teeth, `as shown in Fig. 5. An

end of webbing Eis introduced between the teeth and jaw and the latter then flattened upon the teeth by blows of a hammer or 1n al suitablepress, to engage the end strongly.

The effect of the flattening operation is to curl the points of the teeth inwardly in position to resist the normal pull on the webbing and to lock the engaged end of the webbing by the overlap ofthe jaw F thereon. Thus engaged the end is' securely held with the raw edge completely j aw, and sharp projecting edges of the metal are avoided.-

I claim A slide for the purpose set forth embodying in a single `element a central lbar and outer bars with slots between them, a series concealed beneath the of teeth formed on one edge of said central bar, and a jaw formed integrally on the opposite edge of said central bar with the material bent out of the plane of said bars to produce one of said slots, said teeth extend.- ing toward the jaw and the jaw and teeth extending in opposite directions toward each other and the jaw adapted to overlap the teeth to grasp a webbing end between said jaw and teeth.

In testimony that I claim the invention above set forth I aiix my signature, in presence of two witnesses.

CHARLES R. SEARLE, F. J. GREENE.
