SPECIFICATION forming part of Letters Patent No. 662,305, dated November 20, 19 00.

Application filed December 5, 1899. Serial No. 739,278" lNo model.)

T0 at whom it may concern.-

Be it known that we, IsING RHEINBERG and JULIUS RHEINBERG, manufacturers, subjects of the Queen of Great Britain, residing at London, England, have invented certain new and useful Improvements in Hair- Combs, of which the following is a specification, reference being bad to the accompanying drawings, in which Figure l is a plan of a partly-manufactured comb. Fig. 2 is a transverse section of the same. Fig. Sis a similar section after the wires forming the teeth have been bent, as hereinafter described, and Fig. 4 is a section of the same after the backing-strip has been applied thereto. Fig. 5 is a transverse section, on an enlarged scale, of a comb constructed according to our invention, wherein the teeth are secured in the longitudinal strips by pressure. Fig. 6 is a similar section after the backing-strip is applied. Fig. 7 is a longitudinal section of a portion of the comb, taken on the line 2 2, Fig. 5. Fig. 8 is a side view of a portion of the comb, the backing-strip being partially removed. Figs. 9 to 12 illustrate modifications hereinafter described.

Like letters of reference denote corresponding parts in the several figures.

The strips of wire A A, Fig. 1, which are to form the teeth of the comb, are laid parallel to each other and the required distance apart, (which operation may be facilitated by the use of a suitably-grooved block,) and then longitudinal strips of metal B B, which may be of U section, are placed over the ends of the wires and the Wires are secured in said longitudinal strips by pressure or by pressure andbending, which will hold them firmly and prevent them from drawing out and from being displaced laterally. Having thus formed a ladder-like article, as shown in Fig. 1, we next bend the same along its median line was to form the teeth and to bring the two longitudinal strips B B together, or nearly so, as indicated in Fig. 3. The comb thus formed may be used in that condition; but we prefer to strengthen it by applying thereto a suitable backing-strip O, as indicated in Fig. 4, covering both the aforesaid strips B and affording great rigidity. Each tooth of the comb formed in this manner is thus constisince thesame are only subjected to one bending operation.

In securing the wire teeth in the longitudinal strips by pressure we use dies which are preferably shaped and adapted to form transverse depressions Z), Fig. 7, in the longitudinal strips B between the wires and a longitudinal hollow or bend in the strips B at b, the wires being similarly bent at the same time, the said dies being also adapted to curve the strips B, as indicated in Figs. 5 and 6. When the strips B have been firmly pressed on the wires and shaped as aboveindicated, it will be found that the teeth are securely held and cannot draw out or move laterally. The Wires A are next bent along their median line, as above described, and the strips B are covered and strengthened by an additional backing-strip C placed over them. Said backing-strip is held in position by the spring of the wire teeth. The arch formation of the strips B insures great rigidity. We have found by experiment that the form shown in Figs. 5 to Sis best adapted for the purposes of our invention; but we may vary the shapes given to the strips B. For example, we may use dies that will produce .the bends shown in Figs. 9 and 10 or that will produce flats or depressions on both sides of the wires, as shown in Fig. 11, or on one side, as shown in Fig. 12, besides the transverse depressions in the strips B between the wires. In some instances grooves or notches may be formed in the wires, and the strips B may then be forced into the said notches.

The above-described method of fixing the wire teeth in the backing-strips can also be used in the manufacture of metal combs having teeth of single wires free at their outer ends and fixed at theirinner ends in the strips B, which are pressed tightly upon them.

In another application filed on even date I herewith we have claimed the process or method of manufacture of our improved combs, and we therefore limit the claims in this application to the product.

We claim 1. In a metal hair-comb, the combination of a number of wires arranged parallel to each other, each wire returned upon itself at its median line, and longitudinal metal strips inclosing and secured upon the ends of said wires, substantially as described.

2. In a metal hair-comb, the combination of anumber of Wires arranged parallel to each other, each wire returned upon itself at its median line, and longitudinal metal strips inclosing and secured upon the indented ends of said wires, said metal strips being bent alonga longitudinal line, substantially as described.

3. In a metal hair-comb, the combination of'anumber of wires arranged parallel to each other, each wire returned upon itself at its median line, and longitudinal metal strips inclosing and secured upon the indented'ends of said wires, said metal strips being bent along a longitudinal line, and also having depressions between each pair of adjacent wires, substantially as described.

4. In a'metal hair-comb, the combination of a number of wires arranged parallel to each 5. In a metal hair-comb, the combination of a numberof wires arranged parallel to each other, each wire returned upon itself at its median line, and longitudinal metal strips inclosing and secured upon the indented ends of said Wires, said metal strips being bent alonga longitudinal line,and also having depressions between each pair of adjacent wires, and a backing-strip inclosing said longi tudinal strips, snbstantiallyas described.

6. A metal hair-com b, comprising a number of wires arranged parallel to each other thus strip, and the strip being provided with indentations between thewires, substantially as described.

In Witness whereof we have hereunto set our hands in presence of two Witnesses.
