HAIR-CUTTING DEVICE.

Application filed May 9, 1925, Serial No. 29,150. Renewed April 27, 1926.

This invention relates to certain new and useful improvements in hair cutting devices, and its objects are to provide a hair cutter which embodies a safety razor blade, or similar blade, a comb member and a hold ing member associated therewith and adapted to grip the blade in its working position, and a spring element associated with the comb member and holding member, andarranged to hold the blade through friction.

A further object of this invention is to provide a device of this character in which the blade may be adjusted to different pos1- tions both laterally and longitudinally whereby the complete cutting edge of the blade may be utilized, and to provide a device of this character in which the adjustable elements and the blade are held by friction.

A further object is to provide adevice of this character in which the several parts are made from sheet metal and thereby to p0 duce a hair cutter that is both simple and economical.

A further object of this invention is to provide. a device of this character having the parts constructed and arranged to prevent slipping of the fingers of the user; and to devise an implement with which an unskilled person may cut his own halr or the hair of others.

Another object is to provide a device in which the parts may be readily detached from one another for the purpose of cleaning, or of replacing the parts.

To attain these objects, I prov1de an implement embodying a holder including opposed jaw members, a spring to hold the jaw members in operative engagement, with the cutting blade, and a detachable and reversible double-edged blade supported and moved by the holder; the device belng of small compass and adapted for use with the hand, and adapted, in use, to be drawn from the top of the head downwardly, as in the use of a razor. I

In the accompanying drawings, there is shown a preferred form of the invent on, it

being understood that the drawings do not.

define the limits of my invention, and that minor changes may be made in the con-' struction and operation without departing from the spirit of the invention or scope of the clalms.

More specifically, the comb member 11 and holding members 12 are made of sheet metal or other suitable material, and are of suitable length and breadth to engage with a metal blade 13, having the

knife edges

14 and 15. The holding member 12 has a flange portion bent inwardly and arranged in parallelism with the comb member in the assembled position to more completely engage with the sides of the blade member. The blade and holder members'comprise opposed jaws, and are provided with

integral handles

16 and 17, which, in their assembled position, diverge from their points of contact with the blade, and therefore may be pressed together to release the blade. The holding member 12 and comb member 11 are provided with

projections

18 and 19, which project through the spring member 20, which is pierced with suitable apertures 21, for the said projections, and with apertures 22, through which the handles project. These

projections

18 and 19, afford a means for a secure grip of the operators fingers, and therefore the device may be operated the more uniformly and with greater accuracy. The blade 13 may be adjusted laterally and longitudinally relative to the holder. The lateral adjustment may be for setting the blade for shaving, or for sharpening the blade, or it may be for obtaining a longer cutfor the hair. The space between the projections 23 and E i on t'he-comb member, is greater than the length of the blade, and

therefore, the blade may be positioned with one end abutting against a projection on one end, and will present certain portions ofthe cutting edgebetween' theteeth 25. On shifting the blade toabu-t against the opposite projection, the remaining portions of the blade are presented between the teeth of the (0111b. Therefore, all portions of each cutting edge of the blade may be utilized. The teeth have their extremities 26 rounded. 'ihe holder members are provided with notches E27 and 28, which allow the operator to grasp the blade for adjustment. Both holding members are provided with corrugations 29, engaging with the spring edges 2-30, and serving to retain the holding members in their assembled position.

In the modified form, the comb member Ill and holding member 32, are retained in position by the spring member 33. The comb and holding members are provided with longitudinal grooves 34: and 35 adapted to engage with the et of the spring. In the assembled position, the holding members have their

flange portions

36 and 37 extending in parallelism to hold the blade. The remaining features of the modified form are similar to the preferred form.

In use, to adjust the blade to give any desired exposure of the comb teeth tor cutting the hair a longer or a shorter length, it is only necessary to press the handlestogether sufficiently to release the blade, whereupon the blade may be grasped by the lingers and adjusted, either laterally or longitudinally as desired. The projections at each end. of the spring member, and the handles both serve as a means whereby the user may hold the device firmly. The inclination of the blade effects a shearing cut whereby the hair may be cut smoothly and easily.

In either form of the device, the jaws comprising the comb member and hoiding member are arranged to be in intimate contact with the blade throughout an extensive area; thereby maintaining the blade in the correct position for use, and holding the same firmly for use. In use, the device is grasped between the thumb and second fin ger, the operator placing the index finger between the projections at the end of the spring member, and by this method of holding, the user may vary the angular position of the comb member and blade as desired.

It may be seen from the foregoing that the device is small and compact, economical to make, useful and capable of quick adjustment in accordance with the work to be done and readily manipulated for inserting and removing the blade, and that the blade may be adjusted without removing the same from the holding members.

lVhat is claimed is 1. In a hair cutting device, a tubular spring member having opposed longitudinal edges, a pair of jaw members consisting of a comb member and a holding member having longitudinal corrugations adapted to engage with said longitudinal edges, said jaw members being mounted between the longitudinal edges of the spring member and extending outwardly from the edges of the .a holding member having body portions adapted to fit between the edges of the spring tubular member and urged together thereby, a flange projecting inwardly and integral with the holding jaw member, said flange being substantially in pa 'allelisn'i with the ren'iaining jaw member, said jawmembers extending from the edges of the spring member, and a blade frictionally supported between the jaw member and the flange.
