IMPROVEMENT IN TOOLS FOR MAKING BUCKLES.

Specification forming part of Letters Patent No. 4|,6 [0, dated February 16, 1864.

.To all whom it may concern.- I

Be it known that I, ROBERT DURNING, of Lawrenceville, in the county of Allegheny and State of Pennsylvania, have invented a new and" useful Improvement in the Manner of Constructing Buckles; and I dohereby de elare that the following is a full, clear, and exact description of the same, reference bedug had to the accompanying drawings, makand are employed for harnesses and for simi-. lar purposes.

The invention consists in the employment or use of certainmeans or tools that may be used separately by hand, or so arranged as to be operated by mechanical means with any suitable power, and so constructed as to respectively open the end of the tongue and close the same on the bar of the buckle to form the tubular friction-roller and to adjust the same on the roller-bar of the buckle, as hereinafter fully set forth, whereby buckles of the class specified may be manufactured much cheaper than at present and in a superior manner.

, To enable those skilled in the art to fully understand and construct buckles according to my invention, Iwill proceed to describe it. A, Fig. 1, represents atool composed of two jaws, a. b, the shanks of which cross each other and are connected by a pivot, c, the shank of the lower jaw, b, having a handle, B, attached to it, and the shank of the upper jaw having a pendent projection, O, which is grasped by a vise, the latter firmly holding the tool-wheel in use. The upper jaw, a, has a conical pin, D, at its inner side andnear its back end, and the front part of said jaw is curved, as shown at d. The front end of the lower jaw, b, is curved in a similar manner, as shown at d, and the jaw b, near its back end, has a hole, f, made. in it to receive the conical'pin D when the two jaws a b are closed, the jaw b being represented partly in section in order to show the holef. This tool A is for the purpose of opening the eyes g of the tongues E of the buckle after the latter are forged.

In Fig. 4 a tongue is shown with its eye g in a closed state, and it will be seen that if the tongue be placed between the jaws a b, with its eye 9 over the holef injaw b, and thejaw b forced upward, the conical pin D will pass through t-h'. eye and open the same, as shown in Fig. 5. This opening of the eyegol' the tongue is toenable it to be fitted on the barh of the buckle F. When the eye is opened and fitted on said bar, the eye is closed by pressing it around the bar by means of the curved ends d d of thejaws a b.-

G, Fig. 2, is a tool composed of two jaws,

tj, connected by a pivot, is, the shank of the lower jaw having a handle, H, attached, and the shank of the upper jaw provided with a projection, I, to be graspedby a vise. The upper jaw, z, of this tool G is provided at its inner side with a projection, J, of cylindrical form, which extends the whole width of sai l jaw, and in the inner surface of the lower jaw, 7', there is made a recess or groove, Z, which corresponds in form to the projection J, but

is a trifle larger. By means of this projection J and the recess or groove l'the tubular friction-rollers are formed from a flat blank, K, (shown in Fig. 6,) the blank K being laid on the lower jaw, j over therecess or groovel, and the lower jaw forced upward, so that the projection J will force the blank into the recess or groove Z, as shown clearly in Fig. 2, and form the roller l.

L, Fig. 3, is atool composed of two jaws, m n, fitted on a pivot, o, and provided, respectively, with a handle, M, and projection N,

like the other tools. The jaws m n of this tool are each provided with semicircular recesses o to press the roller 1 around the bar h of the buckle. Two of these recesses, of different dimensions, may be made in each jaw to suit rollers of different diameters, and similar recesses, p, may be made for the same purpose in the outer parts of the jaws t'j.

This invention has been practically tested and found to answer remarkably well, saving much time and labor and performing the work in a superior manner.

Having thus described my invention, what I 2 I I gmno claim as new, and desire to secure by Letters 1211 friction-rollers,and also adjusting them Patent, is v 011 the buckles, as herein set forth;

f'flhe employmentor use, in the manufacture 0 arness and other'similar buckles, of a sev v I ries of tools, constructed substantially as HILiL shown, for the purpose of opening the eyes of Witnesses: the tongues of the buckles and closing the G.
