ELECTRICAL HAIR TRIMMING AND SINGEING INSTRUMENT Filed Oct. 4, 1928 INVENTQR ksgmuel 0. Chase ATTORNEY Patented Jan. 21, 1930 UNETED STATES PATENT @FFIQE SAIv'IUEL 0. CHASE, OF STAMFORD, CONNECTICUT Application filed October 4, 1928.

This invention relates to implements for treating the hair, and has particular reference to a device for trimming and singeing the hair.

Under the present method practiced by barbers, the final trimming of the hair is accomplished by means of shears after the same has been roughly cut initially by the use of clippers and shears. In event singeing of the hair is desired, the barber employs a waxed taper to perform this operation which in addition to entailing further labor and time, is not wholly free from danger while failing to produce a uniform finish.

The present invention primarily contemplates an implement for imparting a final trimming to the hair by a singeing operation for obtaining the beneficial results of said singeing while obtaining a uniform finish.

This invention further contemplates a hair trimming and singeing implement which includes a comb and a heated singeing element disposed relatively to the teeth of the comb whereby trimming of the hair by singeing of the ends of the same may be accomplished by movement of the comb therethrough, thus insuring a uniformly finished appearance to the trimmed hair.

The invention furthermore embodies in a hair trimming and singeing device of the character set forth, an electrically heated singeing element, together with means for compensating for the contraction and expansion of the element and means for shielding said element from drafts which might otherwise tend to impair its proper functioning.

Other features of the invention reside 'in the provision of a device of the character set 0 forth which is comparatively simple in its construction and mode of use, economical to produce and which is highly efficient in its purpose.

With the above recited and other objects in view, reference is had to the following description and accompanying drawings, in which there is exhibited one example or embodiment of the invention, while the claims define the actual scope of the same.

In the drawings:

Serial No; 310,321.

Figure 1 is a side View of the device in its entirety.

Figure 2 is a perspective view of the singeing element and its mounting, with parts shown in section to disclose the underlying structure.

Figure 3 is a cross sectional view taken approximately on the line 33 of Figure 1.

Referring to the drawings by characters of reference, the device includes a base 5 which is in the nature of a plug provided with the usual insulated contacts to be fitted in an electrical socket. The base 5 has extending outwardly therefrom a conductor bar 6 connected with one of the contacts and formed at its outer end with abifurcated eX- trcmity 7 between the furcations of which an arm 8 is fulcrumed at 9 for limited swinging movement. The base is provided further with a laterally projecting arm 10 connected with the other of its contacts, and a singeing element 11 in the nature of a wire of electric resistance heating material is secured to and stretched between the free ends of the

arms

8 and 10. A spring 12 positioned in a recess 13 at the free extremity of the bar 6 is designed to engage with the arm 8 for normally moving its free terminal in a direction away from the arm 10 whereby the element 11 is maintained in a taut condition irrespective of the contraction and expansion of the same when heated or cool. The device further comprehends a comb 14 having teeth 15, said comb being attached to the bar 6 at one side thereof and insulated therefrom by means of screws 16 or other fastening ele ments which pass through the insulators 17. The free terminals of the teeth of the comb are disposed in approximately the same plane with the plane of the element 11 whereby the user may comb the hair through the teeth and present their ends to the wire 11 in order to facilitate the trimming of said ends by contact with the heated element 11 and the singeing of the trimmed ends in the same operation. In order to protect or shield the element 11 against drafts which might impair its proper functioning, a shield strip 18 is attached to the arm 10 and extends outwardly therefrom alongside of the element 11, as

clearly illustrated in the drawings. In practice, the base or plug 5 is designed to be received by a socket 19 having a suitable switch 20 therein for controlling the closing and opening of the circuit from the source of supply of electrical energy. The socket will be attached to or formed as part of a manip ulating handle 21 through which and from which the conduit 22 for the conductor wires leads. V] here the device is to be used in con nection with the usual house current, it is obvious that the voltage must be reduced, and in such instances the ends of the conductor wires will be led through a voltage reducing device 23 of any type desired. The device 23 may be provided with

terminal legs

24 and 25 to be fitted in the usual outlets, and said device may be further provided with a handle 26 for inserting or removing the same from the outlet. It is, of course, understood that if the device is to be used in connection with a battery or an outlet having a reduced voltage, the voltage reducing element may be eliminated.

hat is claimed is:

1. An implement for trimming and singeing the hair including a comb and a heated element spaced from and traversing the teeth of the comb and means extending alongside of said element for shielding the same from drafts.

2. The combination with a comb, of a heated element traversing the teeth of said comb and spaced therefrom for effecting the trimming of the hair by a singeing of ends of the same upon movement of the comb therethrough and a common support for said comb and heated element comprising a base, a bar projecting outwardly therefrom to which the comb is attached, an arm pivoted to the free terminal of the bar for limited swinging movement, a second arm attached to the base and to the free terminals of which arms a heated element is connected and means for normally moving the pivoted arm in a direction away from the stationary arm for maintaining said heated element in a taut condition.

8. The combination with a comb, of a heated element traversing the teeth of said comb and spaced therefrom for effecting the trimming of the hair by a singeing of ends of the same upon movement of the comb therethrough and a common support for said comb and heated element comprising a base, a bar projecting outwardly therefrom to which the comb is atached, an arm pivoted to the free terminal of the bar for limited swinging movement, a second arm attached to the base and to the free terminals of which arms a heated element is connected, means for normally moving the pivoted arm in a direction away from the stationary arm for maintaining said heated element in a taut condition and a shield supported by the stationary from drafts.
