bination and arrangement of parts, greatlyfacilitating the loosening and removal of foreign matter from the hair and further aid- 10 ing in the distribution of the oil from the' scalp to the hair.
Other objects, features, and advantages will hereinafter appear.
In the drawings forming a part of this specification Fig. 1 is a }perspective view of such a comb embodying t e invention;
Fig. 2 is a fragmentary view ofthe side of a blank from which such a comb may be formed;
Fig. 3 is a fragmentary view of a partially formed comb;
, Fig. 4 is an end view of a finished comb;
Fig. 5 is a fragmentary plan view illustratin the action of the comb on the hair;
ig. 6 is'a side view of a single tooth; and
Fig. 7 is a modification of a single tooth.
A preferred form of construction of such a comb is illustrated in the drawings and comprises a handle or back 35 integrally formed with teeth 31 having pointed ends 37, body portions 38 of prismatic form, and curved base portions 39. These curved base ortions form one continuous row at their uncture 40 with the handle or back and pro'ect alternately and oppositely therefrom wit the furthermost parts projecting in the same general direction.
The points and body portions of the teeth are in spaced relation and are alternately arranged in two longitudinal rows, with said points and body portions staggered with respect to eachother. In this respect, it is to be noted that the interdental spaces 33 of each row are directl op osite the teeth of the other row, and t at t e longitudinal. rows are spaced apart, forming the longitudinal space 32. The effect-of this arrangement is to provide tortuous transverse passageways for the hair, as illustrated in Fig. 5.
In the application of the comb to the hair preparatory to its being drawn therethrough, the oints 37 act as wedges, the bodies 38 as gui es to the interdental spaces 33 and therein separate the hair, see Fig. 5, into a number of strands 42, 43, and44 in one longitudinal row (1-6, and these said strands are divided by the teeth of the other longitudinal row c l into smaller strands 45, 45', 46, and 46, and in the'interdental spaces of the said row cd are the strands 47 and 48 formed from the strands 45 and 45 and 46 and 46, respectively.
The comb in motion relative to the strands of hair performs the novel function of causing the strands to pass through the interdental spaces 33 in one longitudinal row, as 4 a/.b, diagonally through the longitudinal space 32 and out the interdental spaces 33 of the adjacent longitudinal row, as od, causing the strands to be drawn against the sides of the bodies 38 of the teeth 31 in a doublecurve formation. These tortuous transverse passageways'cause the strands to be pulled against the sides of said bodies and to ride over the edges or ridges 41, which develops a friction to the passin' strands, causing said strands to have a ten ency to.flatten themselves against said bodies and edges or ridges. This flattening of the strands brings a great portion of the'hair in contact with the edges or ridges 41, giving the hair a scrapin treatment when the comb is in motion. fiy this scraping treatment, the foreign matter which may be attached to the hair is loosened and carried to the ends of the hair and removed. Incidental to this scraping treatment, the oil from the scalp is carried along and, because of its nature, becomes distributed along the hair wit-hbeneficial result.
A modification of the tooth as illustrated in Fig. 6 is illustrated in Fig. 7. This tooth has a columnar twist, the edges or ridges 41 are spirally arranged upon the body of the tooth and, where it is desired, may be used in this form of comb for the purpose of lessening the tension to the passlng strands and increasing the length of the ed es or rid es 41 in touch with the strands 0 hair.
he comb may be constructed of any madescribed, the process of forming terial commonly used for such pu ose but is preferably constructed ofsuitab 0 metal, such as aluminum, by the following described method:
First, from suitable sheet material, a blank is formed, see Fig. 2 having one edge serrated to correspond to the points 7 of t e teeth 31, the opposite edge to correspond to the outline of the back or handle 35, and the ends to corres 0nd to the outer edges of the end teeth of the comb;
Second, the blank as shown in Fig. 2. is
' cut from the oints of indentation 36 on the a series of parallel lines 34, see ig. 3, b cuts of equal length, orming a number of strips attached to the back 35, each strip constituting a whole tooth 31, with the ed es or ridges 41 formed incidentally by sai ting;
Third, referring to Figs. 3, 4, and 6, the ortion of the strips or teeth 31 adjacent the back or handle 35 are bent into a curved formation branching alternately and o positel from their juncture with said bac or han 1e, arranging the bodies of the teeth into their respective rows, and thereby providing the interdental spaces and the longitudinal space which combined provide t e tortuous transverse passageways,
While I have shown and described a preferred and specific embodiment of the invention, I do not limit the construction to the exact details shown but may resort to such changes and modifications as occasion may require and as may come within .the spirit and scope of the appended claims.
1. In the construction of a comb of the class a blank from sheet material, cutting the blank to form strips of tooth form attached to the back or handle thereof and bending an inner part of each of said strips to form curved base portions to position the teeth in rows and to provide tortuous transverse passageways.
.2. In the construction of a comb of the class described, the process of forming a blank having one edge serrated to correspond to" the points of the teeth, the opfposite edge to correspond to the outer edge 0 the back or handle, and the endsto correspondtothe outeredges of the end teeth; cutting the said blank from the points of indentation by a number of parallel cuts of adopted length, made intermediate the ends to form strips of tooth form, attached 1 to the back or handle thereof; and bending an inner part ofeach of the said strips adjacent the back or handle thereof to form curved base portions to position the teeth in rows, and to provide tortuous transverse passageways.
3. A comb comprising a back portion; a
. plurality of teeth projecting alternately and oppositely from said back portion with the operative portions of each of said teeth procutjecting in the same general direction with the points and body portions of said teeth arranged in two spaced longitudinal rows.
4. A comb having two rows of teeth in spaced relation, the operative portions of the teeth of each ofsaid rows arran ed in staggered formation with respect to t e operative portions of the teeth of the other row.
5. A comb having a plurality of teeth projecting in the same general direction, the points and body portions of alternate of said teeth arranged in two longitudinal rows with longitudinal s ace between said rows.
6. A comb aving two rowsof teeth in spaced relation, the operative portions of the teeth being arranged to provide tortuous transverse passageways. j
7. A comb having a plurality of teeth arranged in spaced relation to provide tortuous transverse passageways.
8. A comb comprising a back portion, a plurality of teeth having longitudinalscra ing ridges disposed lengthwise their bo y portions, and curved baseportions projecting alternately and oppositely from said back, the said body portions being arranged in two longitudinal rows in spaced relation, having transverse passageways between the teeth, and the said ridges p110 ecting into the transverse passageways.
9. A comb having a plurality of teeth arranged in spaced relation to provide tortuous transverse passageways, said teeth being provided with longitudinal scraping ridges projecting into said passageways.
In witness that I claim the foregoing as my invention, I afiix my signature this 28th day of January, 1929.
