HAIR-CUTTING nEvIc-E.

Application filed, October 27, 1925, Serial No. 65,173. Y I

The present invention relates" to an im-f provement in hair-cutting devices, and its objects are to provide a device of this character utilizing an ordinary safety razor blade, or blade of similarcharacterfor the cutting element, a holder for the cutting ele ment adapted to grip the same in a cutting position, and other elements associated with the holder whereby the device may be manually manipulated and without clogging by the cut hair.

A. furtherobject is to provide detachable cutting elements and detachable holding elements, whereby the device may be readily disassembled for cleaning purposes, and to provide a device of this character in which the parts are made from sheet metal, thereby to produce a hair cutting devicethat is simple'and economical. i

A further object is to provide a hair cutter constructed to prevent the slipping of the fingers of the user,'either while cutting his own hair or cutting thehair of cthers.

While the drawings show a preferred; form of my invention it is to be understood that I do not limit myself to the precise construction therein exhibited, but that minor changes and alterations may be madewhich are within the, scope of the appended claims.

In the drawings, Figure 1 is a side View;

of a hair-cutting device embodying the featuresof my invention. Fig. 2 is a trans verse sectional view through the holding elements and the cutter; Fig. 3 is a side and detail view of the shaft which is adapted to support the holding elements- Fig. 4 is a side and detail view of the handle. Fig. .5 is a side and detail view of the cutter blade. Fig. 6 is an end elevation of a holding member. Fig. 7 is a side and detail view of the holding member shown in Fig. 6. Fig. 8 I

' is a perspective detail view of a spring ele.

ment adapted to secure the holding mem-. her and comb member to a supporting shaft. Fig. 9 is a side elevation of the comb member showing the inner side thereof.

Referring to the drawings, the handle 11 is detachably secured to a shaft member 12, which serves to support the comb member 13 and the holding member 14. Shaft member 12 has each end 15, threaded to engage with a correspondingly threaded shank 16, on the handle. The holding member 14 and comb member 13, each have bent portions 17, adapted to engage with shaft member 12. The springs 18 extend over and engage with the bent portions 17 thereby operatlvely securing

members

13 and 14 to shaft member 12;. The enlarged ends 15,

serve to prevent the springs 18 from being 14:, are preferably made of sheet metal or displaced. The comb member extends in op similar material, and are retained in position relative to shaft 12, by the enlarged ends'15, thereon. The. blade cutter .19, is provided with cutting edges 21, but a singlevedged cutter may be employed if desired. The handle may be attached to either end of shaft 12, allowing the device to be used with either hand of the operator. Handles 22 are provided on the comb and holder.

Projections 23 are provided, and engage with blade cutter 19, thereby holding an edge 21, firmly against the comb (member. In use, the springs 18, afford means for a secure grip of the operators fingers, while the handle is graspedin the palm of the tudinal adjustmentwill expose all portions ofthe edge between the teeth 20'. The device, in use, is adapted to be drawn from the top'of the head downwardly, as in the use of a razor. After use, the device may be hand. The cutting blade..19, may be ad I justed both laterally and longitudinally to utilize all of the cutting edges. The longi-Y cleaned with facility, by pressing upon the handles to release the cutting blade, and:

passing the device through water. The open space between the handles facilitates the cleaning thereof. "The shaft 1 2 cooperating with springs 18, supportthe holding mem ber 14 and comb 13, rigidly relative to one another, and to hold the cutting blade.

From the foregoing description and drawings, it may'beseen that I have provided a useful andcompact hair-cutting de-,

vice. capable of 1 quick adjustment, and

readily manipulated'for cleaning purposes.

What is claimed is: I 1. Ina hair cutting device, a centralsupporting shaft, a handle detachably secured thereto, a comb member-carried by the supporting shaft, a holding member mounted in opposed relation to the comb, said comb member having a greater width than the holding member, springs engaging with the iii) ' on the jaw members, a blade cutter comb and holdingmembers to retain them in operative connection with the shaft, and

,a blade cutter inserted between the comb and holding member. 7 v

2. In a hair cutting device, opposed jaw members, one of which has a greater width than the other, said wider jaw member having an integral combsection, a shaft supporting the two opposed jaw members,

sorin elements sh e in with said comb C) O Z3 and holding member and maintaining them I in operative position upon the shaft, diverging handles, one extending from each body portion, and a blade cutter mounted between the comb and holding member.

3. In a hair cuttin device posed comb and holding members, said comb member having a greater width than the holding member, a shaft supporting the: comb memher and the holding member, spring elements engaging with said comb member and holding member and maintaining them in operative position upon the shaft, a blade cutter mounted between the comb member and the holding member, and projections upon the comb member serving to hold the blade member with the opposed comb teeth firmly pressed against the cutting edge of inner position relativeto the edge of the holding member arranged to hold the blade cutter at an angle with the comb and with the cutting edge of the blade firmly against the teeth of the comb. V

5'; In a hair cutting device, the combination with opposed jaw members, one jaw member having a greater width than the other jaw member, ofashaft en aging with the comb and holding members and holding them inoperative alignment with one another, curved projections on each jaw'member bearing upon the shaft, spring elements engaging with the said curved projections mounted between the jaw members, and projections holding the blade firmly, against the comb teeth.

6. In a hair cutting device, opposed comb and holdlng members, said comb projecting pressed.

threaded ends on the shaft.

beyond the holding member, arcuate portions integral withthe comb member and with the holding member, a supporting shaft springs engaging with the said arcuate por-' tions toretain the comb and holding member upon the supporting shaft, enlarged and threaded ends on the shaft serving to prevent longitudinal displacement of the comb and holding member, and a handle having a threaded shank adapted to engage with either of said threaded ends on the shaft.

7 7. In a hair cutting device, central supporting shaft, enlarged ends thereon, a hold ing membenan opposed combmember, arcu-' ate extensions on boththe comb and holding member adapted to engage with said shaft, springs urging the comb and holding ,mem-Y disposed between the said arcuate'portions,

her in engagement with the shaft, said enlarged ends serving to prevent displacement of the sprlngs, and a blade cutter inserted between the comb and holding member.

8. In a hair cutting device, a central supporting shaft, a handle therefor, opposed comb and holding members, sprmgs'u'rgmg the comb and holding members into engage ment with the supporting shaft, and a cutting blade mounted between the comb and holding member. I

9. In a hair cutting device, opposed comb and holding members, a central supporting shaft therebetwe en, spring elements serving to hold the opposed comb and holding members in engaging posit-ion, a blade cutter mounted between the comb member and the holding member, projections on the comb member serving to hold the blade cutter with its cutting'edge. firmly pressed against the comb teeth, enlarged and threaded ends on said shaft, and a handlehaving'a threaded shank to engage with either threaded end of the shaft; l

10. In a hair cutting device, opposed'comb and holding members,v each having a body portion,"ane comb teeth on the comb memher, a blade, cutter mounted between the comb and holding members and frictionally held therebetween, projections on the comb member servingto lift the blade cutter and press its cutting edge firmly against the comb teeth, diverging handles oneextending from each body portion, a central shaft be tween the comb and holding members,-f threaded ends on said shaft, and a detachable handle engaging with either of said In testimony'whereof, I'hereun'to Iafiix my signature.
