This invention relates to improvements in hair cutting devices and has special reference to devices having straight handles and means for adj ustably clamping a thin razor blade on the handle near its end for use in shaving,

cutting hair, etc. I

The object of the invention is to provide a device of the kind mentioned, which shall be very simple in construction, which shall be especially adapted for cutting the hair generally and particularly around the ears; which shall have simple means of adjusting the blade for longer or shorter hair cutting; and which shall be adapted to make use of the thin double edged blades now in common use.

Other objects and advantages of the invention will become apparent from the following description and the appended claims taken in conjunction with the accompanying drawings forming part of this specificatlon, and in which:

Fig. 14 is an enlarged fragmentary longitudinal section on the line 14--14 of Fig. 8.

Attention is first directed to the form of device shown in Figs. 1 to 7, inclusive.

As shown therein, the device consists of a handle member 6 having an enlarged palm 7 at each end thereof.

The end portions 7 are triangular in transverse cross section, having forward edges 7 which are quite tapered in the manner of thin wedges and rear edges 7 which are more quickly tapered.

The thin edges 7 of the end portions 7 are provided with transversely extending, parallel edge slots 8 arranged to provide a series of comb-like teeth 9.

The two end portions 7 are duplicates of each other except that they are arranged right and left for convenience in use.

The description of'one end'of the device will suifice for both.

At each end, means are provided for clamping a thin razor blade 14 against the flat side of the palm 7. This means consists of a clamping plate 12 which is provided with 7 short projections 13 which are arranged and adapted to enter the usual guide holes in razors of this kind which are in common use.

For holding the plate yieldingly pressed toward the palm 7 to hold the razor blade firmly clamped in position, a spring member 15 is provided. This member is in the form of a flat spring, one end of which is secured to the handle 6 between the end portions 7 by a screw 16, and its other end, in the form shown, is provided with a projection 17 arranged and adapted to be received in a central opening 18 in the clamping plate and also project into a central opening in a razor blade 14. 35

For the purpose of retaining the operating edge of the razor blade substantially parallel with the comb teeth 9, the palm 7 is provided with transversely extending guide slots 10 and the ends of the plate 12 are bent to provide parallel guide flanges 11 which fit in the guide slots.

The movement back and forth of the plate and the blade is not very much and there is suflicient freedom in the engagement of the parts to allow this movement without binding.

Preferably, the palm 7 is curved or inclined on its toothed edge to provide a close engagement with the operating edge of the razor blade 14 for the purpose of preventing hairs becoming wedged in between the blade and the teeth 9. The longer plane portion on the back of the palm 7 is adapted to be pressed against the skin or head when the device is being used and the adjustment of the blade from and toward the teeth is for the purpose of regulating the depth of hair left on the head. That is, when the edge of the blade is moved out toward the ends of the teeth 9, the device will cut the hair quite short and when moved back towards the bases of the teeth,

it will not cut the hair so short.

In Figs. 8 to 14, inclusive, I have shown a form of the devices which is different in several details than the form so far described.

The modified structure has a handle 6' quite similar to the handle 6 in that it is double ended and has means for yieldingly clamping a thin flat razor blade on each end.

The flat palms 7 at each end are likewise triangular shaped in cross-section, similar to the palms 7, each having a long thin tapered edge 77 and a more blunt tapered edge 77*.

'As shown, each of these edges are slotted in from the edge forming comb-

like teeth

8 and 8", respectively. The comb-like teeth are formed on each edge of each end to permit the use of the blunter edges 7 7 b in cuttinghair as Well a; the opposite edges. These blunter edges are especially adapted for trimming or cutting the hair around the ears, these places being the most difiicult to cut with any'unguarded instrument Without danger of cutting the skin.

In this form, the blade holding plate 25 is provided with projections 26 which are received in slots 27 formed in the enlarged end 7' and the clamping plate 25 is adapted-to clamp a double edged thin razor blade 28 be tween the plate and the palm 7. The projections 26 are adapted to register with the guide openings in a well known make of razor blade and to hold the blade against rotation. The free ends of the projections 26 are adapted to slide back and forth in the slots 27, which may be arcuate in form, as shown, to avoid undue friction.

As in the form first described, a flat clamping spring 29 is provided for yieldingly holding the plate 25 against the palm 7. This spring is pivotally engaged to the plate 25 by means of a projection 33 which is received in the usual center hole of the blade and its free end projects through the blade into a slot 34 in the palm 7 similar to the arcuate slots 27. The spring 29 is secured to the handle 6 at its opposite end by a screw 31, provided with a shoulder 32 slightly thicker than the thickness of the spring, and the spring end is slotted, as shown at 30 to receive the shoulder part of the screw.

This construction allows transverse movement of the clamping plate 25 and razor blade 28 relative to the

comb portions

8 and 8" to regulate the amount of hair removed.

Either one of the comb portions can be used for cutting hair or the like, as the blade 28 is shiftable from one edge to the opposite edge and the blades can be adjusted relatively to the edges for cutting off more or less hair or leaving more or less hair uncut, as may be desired.

As the two ends of the device are reversed as to each other, that is, as one is right hand and the other left hand, the device is well adapted for trimming the hair on a human head when it is necessary to trim around bot the left ear and the right ear.

As many modifications of the invention will readily suggest themselves to one skilled in the art, I do not limit or confine the invention to the specific details of construction or operation herein shown and described.

I claim:
