ELECTRIC COMB FOR THE HAIR.
Application filed March 25, 1927, Serial No..178,1 86, and in Great Britain August 30, 1926.
My invention relates to improvements in electric hair combs.
The object of the present invention is to provide an electric hair comb in which comb members are provided in spaced rows, being directly in circuit with a removable battery, forming part of the comb, the circuit being closed by the comb members being passed through the hair.
In order that the present invention may be the more readily and clearly understood, reference is made to the accompanying two sheets of drawings in which Fig. 1 is a sectional side elevation and Figs. 2 and 3 sectional plan and end views respectively of one form of comb according to the present invention.
Fig. 4. is an end sectional view of a variant construction.
Figs. 5 and 6 are side and end views res ectively of another modification in which the battery is mounted at the back of the comb members, while Figs. 7 8 and 9 are respectively side, plan and end views in section'of a further variant.
Fig. 10 shows a lamp and clip capable of being attached to the comb for use as a torch.
According to one feature of the present invention two spaced apart parallel rows of teeth or comb-members 1, 2 are mounted on or in an insulating strip 3 by which the teeth 4, 5 of the comb-members are supported in fixed non-contacting relationship to make them operative for combing, and preferably with the teeth of one member in staggered relation with respect to the teeth of the other.
The points of the teeth may fall in different planes or in the same plane. If in the same plane the ends of the teeth may lie in that plane forsome or a substantial part of their length.
The insulating strip 3 may intrude below the roots of the respective rows of teeth and such intruding portion may be rounded so as to protect the hair from injuriously contacting with such roots should finishing difiiculties have stepped in to cause these to have been left in a rough condition.
A convenient form of the insulating strip 3 is that of a rod of, for example, round or half-round section, having parallel longitudinal grooves 6, 7 in which the backs of fiat strip-like comb-members '1, 2 are fixed by insulated rivets 8 or screws of insulating material.
The material between the comb-members 1, 2 may project as a longitudinal smooth edge rib 9 which intrudes between the rows of teeth below the roots thereof.
In this arrangement the comb-members 1, 2 may be formed separately by stamping from suitable metal strip.
Otherwise, associated comb-members 1, 2 may be formed out of one piece of strip in which in the blank the respective rows of teeth project on opposite sides of a medial continuous strip which by appropriately folding the blank longitudinally upon itself is given a part cylindrical or some other shaped fold, 10, Fig. 4 in which is inserted and fixed an insulating member 11, the combmembers 1, 2 being electrically separated by cutting a slot 12 along the fold, for example, along the top of the fold.
Comb-members 1, 2 thus insulated and supported may be inserted in a slotted insulating sleeve 13 which may have a handle which may be as an integral or separate prolongation thereof.
A comb such as is hereinabove referred to may have a chambered back 14 or handle 15 in which is carried a battery 16 suitably electrically connected to the comb-members.
For example, the comb may have a (hambered back 14: of insulating material to receive a battery 16 lying along the back of the comb.
The battery may have the positive terminal 17 at one end and the negative terminal 18 at the other end. and one comb-member may be extended to form or may have a fixed conducting strip 19 to contact with one terminal, and the other comb-member may electrically connect with a folding contact 20 or some other kind of temporary or permanent switch to make contact with the other terminal.
Or, as another example, the comb back insulation may beprolonged and adapted to receive a screw-on or push-on chambered handle 15 of insulating material in alignment with the comb back to receive a battery, for example, a battery 16 similar to that above referred to.
This handle may have a screw-on or pushon cap 21 of insulating material to engage its free end preferably up to a definite stop 22 by which a push-in or screw-in switch component 23, carried by the crown of the cap 21, is properly positioned each and every time the cap is replaced.
As before, the switch, whether temporary or permanent, relates one comb-member with one terminal of the battery through the conducting strip 24, and the other comb-member is appropriated electrically connected wlth the other terminal, for example, through the conducting strip 25.
Yielding means may be interposed between the comb-members 1, 2 and the battery if desired, and such yielding means may be the electrical conducting means 25.
A simple serviceable switch construction comprises a springy conducting strip 24 leading from a comb-member along the inside of the chambered handle 15, the free end being folded to lie behind a stud terminal at one end of the battery 16 and being adapted to be pressed into contact therewith by the push-in or screw-in button or stud 23 mounted in the crown end of the cap 21.
The fixed end of the conducting strip 24 or 25, may be inserted and gripped between or soldered to the back of the corresponding comb-member and the groove in which the comb-member is inserted.
Use may be made of a comb substantially as hereinbefore described as an electric torch by appropriately relating an electric lamp to the battery.
For example a lamp 26 may be supplied having spring blade terminals 27, 28 adapted to be pressed between or over the comb-members 1, 2 and spring open into contact therewith and close the circuit across the combmembers.
Gonnections such as pin and socket, two way switches, and others may be used for this alternative use as a torch.
An example of a variant construction is shown in Figs. 7, 8 and 9 having two combmembers 29, 30 of suitable conducting material preferably steel. The comb-members 29, 30 as shown may be of the well known wire tooth construction, with the usual metal back 31, the teeth of the comb-members extending for about one half of the length of the metal back, the other half of which constitutes the handle or a part thereof.
As in the previously described embodiments, the comb-members 29, 30 may be insulated from each other by the insulating member 3 which has shallow longitudinal grooves 6, 7 to receive the backs 31 of the comb-members. The comb-members are secured to the grooved insulating member 3 by rivets or screws 32. The holes to receive these rivets or screws 32 are drilled through both combs and the rib 9 of the insulating strip 3, one half of the holes 33,34 in each comb being enlarged, and the enlarged holes 33 in one comb coinciding with, the nonenlarged holes 34 in the other comb. The enlarged hole in one comb enables the rivet and rivet head to be passed therethrough, so that finally the stem of the rivet fits snugly into the corresponding small hole in the other comb, while the head of the rivet is seated in the side of the insulating rib 9 so that the rivet shall not bridge the two comb members.
The handle portions of the combs are bent in such a manner that together they form a prong 35, the root portion of which is close to the teeth of the combs. Into this prong is mounted longitudinally an electric battery 16 such as hereinbefore referred to, one pole of which is at the free end of the prong and the other pole is at the root end of the prong. To the free end of one of the prong members a socket or clip (not shown) may be provided for the support of the corresponding end of the battery, a spring 36 of conducting material is fixed to the free end of one prong.
A handle cover is provided in the form of a sheath 3?, made of insulating material. The outer end of the sheath is closed, this portion longitudinally has a threaded hole to take the screw 23 for the purpose of adjusting the contact spring 36 to the pole of the battery 16. The sheath 37 is moulded to the form of the contour of a cross section of the prong members and the enclosed battery and is adapted to slip into position over the prong and battery and be frictionally held in position thereon by slightly bowing the prong members.
The spring 38 at the inner end of the battery may be caused to contact with the battery pole by a lever hinged at one end in a longitudinal slot in an extended portion of the insulating member 3.
The lever at its free end is formed in a suitable manner so as to be operated by the thumb or finger pressure of the hand operating the device. It is supported against pressure by a suitable spring fixed preferably to the sheath.
WVhat I claim is 1. An electric hair comb comprising an insulating strip, two spaced conducting comb members carried by said strip, a chambered handle connected to said strip, a removable battery in said handle, a springy conducting strip leading from one comb member along the inside of said handle, the free end of said strip lying near one terminal of said battery, a push-piece. for pressing the free end of said strip against said terminal, a second strip connected to the other comb member and contacting with the other terminal of said battery, said comb members being thereby connected directly in circuit with said battery, the circuit being closed by said comb members being passed through the hair. 7
