JOSIAH B. GATHRIGHT, OF LOUISVILLE, KENTUCKY.

TRACE-CARRIER.

SPECIFICATION forming part of Letters Patent No. 628,529, dated July 11, 1899.

Application filed June 23, 1898- .Serial No. 684,253. (No model.)

To all whmn it may concern.-

Be it known that I, JOSIAH B. GATHRIGHT, a citizen of the United States, residing at Louisville, in the county of Jefierson and State of Kentucky, have invented certain new and useful Improvements in Trace-Carriers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompany ing drawings and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention has particular reference to that type of combined back-band buckles and trace-carriers which are made of sheet metal and with the hook and buckle portions stamped therein and its object is to provide a simplified and cheapened device which will be most strong and durable in construction and most efficient in maintaining its adjusted position upon the back-band by friction alone and also to provide one which may be quickly attached to or detached from a back-band and will not destroy or weaken the latter.

- object is accomplished by the construction modified form.

The same reference characters designate the same parts in the several figures.

The base-plate A is made wider at its upper end than at its lower end, and its said upper and lower ends are of equal depth, and their respective curves at and a are of the same radius, so that when said base-plates are cut from a strip of sheet-steel or other suitable sheet metal having a length that is a multiple of a base-plate anda width the same as the height of the base-plate no material is wasted or lost except the small triangular pieces 00 in the corners between two adjacent base-plates, as indicated in Fig. 3,

This

thus resulting in a great saving of material in comparison with sheet-metal trace-carriers heretofore proposed. By forming said baseplate with square corners, as may be done, the pieces a: will he saved; but the construction shown is preferred. In addition to such saving of material the described form of the base-plate gives the latter a stem or narrower part of such width that the hook B, formed therein for the trace-chain, will be so arranged thereon as to provide in said baseplate and at each side of and below said hook Wearing plates or portions Z) for separating the trace-chain from the'back band I and for supporting and stiffening said hook. Said hookB is formed by properly slitting the baseplate and punching or stamping the metal bounded by said slits into curved orhook form, and in practice the point I) of said hook will be in the plane of the base-plate, so as to cause it more efficiently to hold the tracechai'n.

The upper portion of the base-plate is preferably formed with two series of slits 1 l and 2 2, extending longitudinally thereof, and the metal between said slits is bent or punched outward beyond the plane of the base-plate, thus forming two resilient tongues O and D, occupying a plane outside the plane of the base-plate, an intermediate separating-bar E and a rigid top bar F in the plane of the remaining portion of the base-plate, and openings C and Dbelow the respective tongues, which openings and tongues are of the same dimensions, so that the longitudinal edges of the latter will be in the horizontal planes of the longitudinal edges of the former. In or-. der that said tongues may be bent from the base-plate at their ends without distorting or weakening the device and also to the end that the tongues shall be resilient, so as to in Fig. 4. When slit at the ends, said slits will preferably be at the right and left, re-

spectively, and when slit at an intermediate point they will preferably be at the longitudinal centers thereof.

When the device is applied to a back-band, the latter extends under the bar F, through opening forward and upward over tongue C, rearward and upward back through said opening 0, and around the edge of the interinedi'atebar E, thence along the under surface of the latter, through opening D, and forward and upward over the tongue D,thence rearward and upward back to and through said opening D, and thence downward along the under surface of the narrower part of the base-plate, as shown in Figs. 1 and 2. It will be seen that well-defined loops are formed by to give it a tendency to slip on the band the tongues will'be pressed down upon said loops and exert a clamping action on them, which will greatly aid the friction caused by the indirection given to the band in passing through the openings and around the tongues to securely hold the trace-carrier in position. In practice it has been found that the friction caused by the indirection of the band is not sufficient in itself to securely hold the tracecarrier in position, and the clamping action of the resilient tongue is therefore a valuble improvement on the sheet-metal trace-carriers heretofore proposed.

Owing to the greater efficiency of the slit tongue for holding the back-band, one tongue will secure it; but two tongues will cause more uniform wear and strain upon the two edges of the band when the slits are at the ends of the tongues, and that is preferable as affording greater resiliency by reason of the greater leverage.

increasing the hold of the buckle thereon.

It will furthermore be seen that the most important feature of slitting the tongues transversely causes the buckle to hold to the band by friction alone so tightly as to avoid all possibility of accidental slippage, while at the same time it enables said tongues to be bent at the ends without weakening the device.

Having thus described the invention, what I believe to be new, and desire to secure by Letters Patent, is

1. A trace-carrier, form ed of resilient sheet metal, and having slits in its base portion and the metal between the slits bent out to form a clamping-tongue occupying a plane outside that of the base, said tongue being slit transversely to give resilience and enable it to be bent without stretching the metal, substantially as described.

2. A resilient sheetmetal trace-carrier, having a plurality of pairs of parallel slits in its base portion and the metal between each pair of slits bent out and separated at one end from the base to form resilient clampingtongues occupying a plane outside that of'the base, each tongue being separated from the base at an end opposite the separated end of the adjacent tongue, substantially as and for the purposes specified.

In testimony whereof I affix my signature is presence of two witnesses.
