HAIRCUTTING DEVICE Filed July 19, 1949 Patented Dec. 30, 1952 HAIRCUTTING DEVICE Henry Elliott, West Molescy, England Application July 19, 1949, Serial No. 105,625 In Great Britain July 31, 1948 6 Claims. 1

y This invention relates to hair cutting devices and the like and has for its main object to provide a device for enabling a person to out either his own hair or anothers hair without difficulty and without the necessity for any special training in the art of hair cutting.

j The invention accordingly consists in a hair cutting device constructed in the form of a safety razor wherein the blade is adjustably arranged with respect to a toothed guard member in such a way as to predetermine the length to which the hair on a persons head is to be out.

The invention also consists in a hair cutting device comprising a safety razor having a blade secured between a head part and a toothed guide member in such a way that the distance between the cutting edge of the blade and the toothed edge ofthe guard member may be adjusted.

According to the preferred arrangement, the

head part of the razor has one or more locating stops or projections which pass through the blade and are slidably mounted in corresponding slots in the guard member, means being provided for securing the head part and blade in any selected position.

If desired, the device may be provided with an auxiliary locating member preferably of comb or tooth-like form for determining the angle between the blade and a person's scalp during the cutting operation.

The invention will be more completely understood from the following detailed description which is given in conjunction with the accompanying drawings, in Which- Figures 1 and 2 are end and side viewsrespectively of a hair cutting device constructed in accordance with the invention;

Figures 3 and 4 are end and side views respectively of a modified form of hair cutting device;

Figures 5 and 6 are end and side views respectively of a further modified form of hair cutting device; and

Figure 7 illustrates in perspective the guard unit of the hair cutting device shown in Figures 1 and 2.

Referring first to Figures 1 and 2 of these drawings, the device is based upon the construction of a safety razor and has a handle I, a head part 2 of slightly arcuate shape, and a double edged blade 3. This blade is disposed between the head part 2 and a guard member 4 which is of arcuate shape and has a set of

teeth

5 and 6 on either edge, this guard member being considerably wider than the guard usually employed in a safety razor so that the edges of the guard member extend a considerable distance beyond the cutting edges of the blade. This guard member 4 is provided with three parallel slots I, 8 and 9 and the head part 2 of the razor has three projections which pass through apertures in the blade 2 and register with the slots I, 8 and 9, the centre projection being screw threaded for engagement with the end of the handle I and the other two projections being slidably arranged in the two outer slots 1 and 9. With this arrangement if the handle is unscrewed sufiiciently to free the guard member 4, the latter can be moved in either direction, the projections on the razor head sliding in the

slots

1, 8 and 9 until the desired position is reached, whereupon the handle I is again screwed up securing the blade firmly in. position, the distance of the edge of the blade from one or other of the toothed edges of the guard determining the distance of the edge of the blade from the scalp and thus determining the length of hair to be retained after the cutting operation.

It Will be seen that the teeth 5 on one edge of the guard 4 are shorter than those (6) on the other edge of the guard so that if a close cutis desired the blade is set with respect to the short teeth 5, while if a long cut is required the blade is set with respect to the longer teeth 6, the

slots

1, 8 and 9 and the

teeth

5 or 6 being so related that the maximum cut provided by the teeth. 5 corresponds substantially with the minimum cut providedby the teeth 8, so that a continuous adjustment may be provided first by the teeth 5 and subsequently bythe teeth 6 according to the length of cut desired. I

In order to ensure that the blade is heldat the correct angle to the scalp during the cutting operation the guard 4 is provided with a pair of upstanding side arms I0 and I I, these arms being joined together by a transverse yoke piece I2 on which are mounted a plurality of teeth I3 which project on either side of the yoke piece I2 and correspond in length with the

teeth

5 and 6 so that the ends of these teeth rest upon the scalp during the hair cutting operation and prevent the device from being tilted over beyond the desired position, the correct position being assumed when both sets of teeth, i. e. I3 and 5 or I3 and 6, are in contact with the scalp.

In the modification shown in Figures 3 and 4, the handle I of the device is replaced by a short junction member I5 and the guard which in this case is made fiat instead of arcuate shape is provided with a pair of outwardly extending side handles I6 and Il. The guard is provided with three slots I, 8 and 9 as before for permitting adjustment of the blade and head part with respect to the guard, but in this case the side arms and yoke piece are dispensed with and instead the head part E8 of the razor is provided with three upstanding triangular shaped plate members i9, 29 and 2! which are adapted to rest upon the scalp and determined the angle of the device during cutting.

In the modification shown in Figures and 6 the deceive has a handle 1 and an arcuate shaped guard 4 similar to that provided in the arrangement shown in Figures 1 and 2, but in this case the head part 22 of the razor is provided with an upstanding comb-like member 23 which serves a similar purpose to that of the triangular shaped plates '28 and 2| of Figures 3 and 4, the teeth of the comb 23 being adapted to rest upon the scalp so as to determine the angle of the device during cutting.

Any of the arrangements hereinbefore described may be made substantially of metal or plastic or, if preferred, they may be made partly of metal and partly of plastic and may be suitably coloured as desired.

I claim:

1. Hair trimming device comprising a toothed guard member for use with a safety razor blade and a guide member for determining the angle between said guard member and a persons scalp during the trimming operation, said guide member comprising a pair of upstanding arms extending from opposite ends of said toothed guard member and a bridge piece carried by said upstanding arms and disposed between them, said bridge piece and said upstanding arms forming with said guard member an attachment unit.

2. Hair trimming device comprising a toothed guard member for use with a safety razor blade, and a guide member for determining the angle between said guard member and a persons scalp during the trimming operation, said guide member comprising a pair of upstanding arms extending from opposite ends of said toothed guard member, and a bridge piece disposed between said upstanding arms in the form of a yoke, said bridge piece and said upstanding arms forming with said guard member an attachment unit.
