Application filed July 24, 1916, Serial No. 111,044.

To all whom it may concern:

Be it known that I, ALBERT F. Cox, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Combs, of which the following is a description.

My invention belongs to that general class of devices known as combs, and relates particularly to a built-up comb of suitable material, or a style of comb having a plurality of separable teeth suitably supported and secured together. The invention has among its objects the production of a device of the kind described that is simple, ornamental, durable, eilicient and satisfactory. It has particularly as an object the production of a comb in which the separable teeth are securely hid in place and reinforced against rotation on their support, and one in which the handle is likewise rigidly secured in place so that it will not work loose. Many other objects and advantages of the construction herein described will be obvious to those skilled in the art from the disclosure herein made.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described,

and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

Renewed September 24, 1918. Serial No. 255,528.

I have found by experience that a built-up comb substantially of the type illustrated may be weak in two places. In one place after continuous use for some time the teeth are apt to become loose on the supporting bar, and be rotatable thereon, or separate thereon, and in the other place the handle is apt to come loose. In either case the usefulness of the comb is considerably impaired.

With the present construction the separable teeth are secured and tightly clamped on their supporting bar, and the bearing of the teeth on the support indirectly increased so that they do not work loose on the bar so that no relative movement is permitted. They are also tightly secured or clamped together, and in such manner that they may be tightened by the user if desired, so as to securely maintain the teeth together whereby'the hair will not be engaged between the teeth or spacer blocks. I also securely lock the handle in place, and in such manner that it may be tightened up from time to time if found necessary.

In the preferred construction shown, 1 represents a suitable tooth supporting bar, which is preferably square, or rectangular, hexagonal, or similarly formed in cross section, and upset or capped at one end, as at 2. The part 1 may be madeof any suitable material, the length of the same depending upon the length of the teeth which are to be used, or the size of the comb. Each of the teethare individual or separable and may be made of sheet metal, or the equivalent, formed in any of the well known ways. As shown, the teeth each consist of a shank or hair-engaging part 3, provided with a. suitably formed head 5, the head prong being ofl'set, if desired, at Jr, for the reasons hereinafter mentioned. The head 5 is formed with an openin or aperture 6 therethrough, the contour of the opening depending upon and corresponding to the cross-sectional shape of the supporting bar 1. I also show a slight shoulder or offset, as at 7, on the head 5. The teeth members are arranged upon the bar substantially as shown in Fig. 1. To space the heads, however, as well as space shanks to form the teeth, I-provide spacing members 8, as shown in Fig. 5, the same being substantially of similar contour to the heads 5, provided with openings or apertures 9 therethrough, corresponding with the apertures 6. These are arranged between each Referring to this figure, it will be noted that the spacing blocks or members 8 rest upon the face or shoulder 4, that is interengaging with the teeth, and that the face of the shank 3 extends slightly beyond the spacing members so as to engage at the shoulder 7 of the next adjacent tooth at that side. In the case of the end teeth, however, as shown in Fig. 3, that is tooth 10, it may be merely a straight tooth, the same being slightly reduced, as at 11, if desired, so that the space between this tooth and the adjacent tooth corresponds with the spaces between the other teeth. While the construction shown in Figs. 3 and 4 may be considerably simplified, it will be noted that although the head 5 is comparatively thin or of slight thickness, owing to the engagement with the spacer block in the manner described, the tooth head has in effect a bearing on the bar 1 equal. to the thickness of the head and the spacer block. In addition, owing to the engagement of one tooth with the adjacent tooth at the shoulder 7, each tooth is substantially reinforced by the other tooth, so that if any undue strain is brought on one or more teeth, a portion of the strain will be carried by the other teeth, thereby preventing any slight wear about the edges of the openings 6, which would permit a rocking upon the teeth on the bar 1.

As shown in Fig. 1, the bar 1 is of sufiicient length to project beyond the end tooth, and the same is preferably threaded from the end adjacent to the end tooth. It is preferably, however, not threaded completely to the end tooth, but only a portion of the way. Arranged to engage the threaded end 14 is a clamping member 15, which is preferably recessed or countersunk, as at 15, so as to clear the end portion of the bar that is not threaded when the same is turned down into operative position. They are also tightly secured or clamped together, the construction providing for the ready adjustment of the clamping means by the user, the head portions 5 of the teeth being maintained in close relationship with the spacer blocks whereby the hair will not be engaged between the head portions of the teeth or the spacer blocks. I also securely lock the handle in place, the connection being such that it may be tightened up from time to time if found necessary. The teeth may be made much smaller and finer with the spaces narrower than is possible in securing the teeth from a solid bar.

While any suitably formed handle may be provided, I prefer to construct the handle with a'supporting bar 16, threaded as at 17 for engagement with the clamping member-15. The bar 16 is preferably square, hexagonal, or of similar form, so that when the end is turned down and threaded, a shoulder is provided between the body of the bar and the threaded end 17. The bar 16 may carry any convenient form of handle, a spirally twisted wire handle 18 being shown. In the construction illustrated the end 19 of the spiral handle 18 is preferably flattened and brought about the end 17, so that when the bar 16 is screwed into place, the end 19 of the handle is securely clamped between the shoulder and the clamping member 15. The opposite end 20 may be twisted about the bar, as most clearly shown in Fig. 2, so as to closely fit the same. By so constructing its end and clamping the other end of the spiral handle, the same cannot be turned'upon the bar 16. I have shown a washer or plate 21, and a ring 22, for preventing the movement of the end 20 toward the outer end of the bar, the ring 22 looking the washer in place, as well as affording a convenient method of supporting the comb when it is desired to hang the same up.

' A modified tooth is shown in Figs. 7 and 8, in which 26 represents the shank or body of the tooth, which is provided with a head 24, having an aperture 25 therethrough of suitable contour. In this case I form the spacer block 26 integral with the head 24, the same having an opening 27 therethrough, corresponding with the opening 25. The extending end 26 may be bent down, as indicated in Fig. 8, forming a spacing block 26, which is integral with the tooth. It will be noted. by referring to Fig. 8, that the tooth bearing on the supportingrod will be con-' siderably increased by this construction- The form of tooth shown in Fig. 9 is somewhat similar to Fig. 7, in that the spacing block is integral with and forms a part of the head of the tooth. In this form 28 represents the tooth, having a head 29, the sam being shouldered as at 30 so as to increase the thickness of the head relative the tooth, and space the teeth. The head is provided with an opening 31 therethrough so as to engage the supporting bar.

In Fig. 10, 32 represents the tooth, having a head 33 arranged to fit over and engage on the bar 34. In this case, however, the bar 34 is split for a portion of its length, and extends through the two apertures 35 in the head 33. The spacing block 33 is shown as separable from the body of the tooth, and is merely a small plate similar teeth have upon the supporting bar, the teeth do not wear about the apertures in the heads until they become loose upon the rod. The same is further made more durable by providing the clamping member 15, and securing the handle thereto, as should the handle ever work loose, this would not in any way permit the teeth of the comb to work loose. The wire handle is extremely durable, and does not usually overheat. It is also convenient to handle by the user.

Having thus described mv invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is I 1. In a comb of the kind described and in combination, a supporting bar, teeth mounted thereon, said bar projecting beyond the teeth at one of its ends, a part arranged on said projecting end, said part of suflicient length to abut against the end tooth adjacent said bar end, and to extend beyond the end of the bar at its other end, a second bar secured to the extending end of said part, and a handle carried by said second bar.
