2. To provide an improved means of adjusting a hair cutting device that it ma effect a close cut or otherwise at the wil of the operator.

3. To provide an im roged means of securely holding the cuttlng unit or blade in a hair cutting device.

. 4. To provide an improved means of securing the cutting unit of a hair cutting de vice to its body portion.

5. To rovide an improved means for withdrawing or extending the guard portion of a hair cuttin device.

6. To provide an improved run in which the ard portion of my device is intended to slide. I

7. To provide an improved blade holding device that adequately'protects the blade, and through integral means secures the same in position.

I 8. To provide an improved method ofhinging the blade holding portions to a' hair cutting device.

9. To provide a blade holding device having thereon means of protecting the inner edge of the cutting blade from contacting with the holding frame of a hair cutting device.

10. To provide an ,improved means of holding the cutting blades in their operating position.

11. To jack for the operating of the guard portion of my device. And to secure other advantages, many of which will be hereinafter referred to in the description of the various parts.

vice showing its general appearance assem-j bled ready for use. i

Fig.- 2 is a view showing a section through line 2-2 of Fig. 1 with one blade holding unit in position to receive a blade.

Fig. 3 is a longitudinal section showing my improved adjustable guard.

Fig. 4 1s a view of the inner side of my improved blade carrying unit.

Fig. 5 is a view showing the inner side of Q my improved blade carrying unit to accommodate a single edge blade.

Fig. 6 is a view of the double edged outtin blade used in my device.

ig. 7 is a view of a single'edged cutting blade for use in the modified single blade holding unit shown in Figure 5.

Fig. 8 is a view of my improved blade holding unit locking pin.

Referring again to Fig. 1, A designates Q the handle of my improved device. B is the guard. C designates the blade holdin unit. D1 shows a movable hin ing pin wit its inner end tapered at D an its outer end knobbed at D E is a hinging lug or projection on the handle A, through which lug the pin D passes in forming a hinge with the lugged portion of the blade carrying unit G. F designates the blade holding unit tension s ring, hinged at G on the handle unit A. is a thumb nut turning on the threaded portion Lthe operation of which furnishes regulating means of projecting or withdrawing the teeth on the guard unit B which moves to the desired positions of ad-' justment in the pocket Q. (See Fig. 3.)

Referring again to Fig. 2, J designates a two ed e cutting blade as used on In -device. is a projecting lip upon the lade carrying unit C shaped to engage the edge of. the orifice, in the blade J, next to the used cutting edge, (see also Fig. 6) so as to prevent contact of the unused cutting edge with the body portion of m device.

Referring again to guiding pin on the handle unit A, operatin in the slot M in the guard B, so as tofurnis at all times a'steadying force on the uard hooked projection beneath which the blade ig. 3, L designates a J fits and is held. P designates a projec-..

tion on the hinged leaf S, which extends throu h an aperture in the blade carry ng unit Said projection P is shaped to engage the edge of the orifice, in the blade J, next to the unused cutting ed e, and in conjunction with the projection operates to firmly hold the blade J in its cutting position on the unit C.

Referring again to Fig. 5, N' shows a lipped projection on my modified single edge blade holding unit. K designates a shoulder on the modified single edge blade holding unit C against which shoulder the back of the single edge blade rests and is held. P shows a projection on, the hinged portion S which projection extends through the aperture in-the unit 0', and engages the edge of the reinforcement on the back of the blade and locks the single edge blade in its cutting position on the single edge blade holding unit C. Similar letters refer to similar parts throughout the several drawln s.

Iy novel and improved safety hair cutting device comprises the carrying handle A, which may be of any design consistent with its purpose, to which are hinged a series of blade holding units, tensioned in their operating position b means of the holding sprin F. (Fig. 1 Intermediate the blade hol ing-units the guard B, in the ocket Q, is re lated to any desired proection by turning the thumb nut H upon the threaded portion I, which turning in the slot R causes the guard to extend or recede at the will of the operator. (Fig. 3). The operation of the pin L in the slot M insures the guard moving uniformly straight, and avoids binding.

The portions C swing on their'hinges by withdrawing the pins D so as to eliminate the tensioning force upon the spring F, thus making possible the easy removal of the cutting blades.

t will be understood that while the appended claims are drawn in the singular they as well cover any number of the units described when used in series.

Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States.
