8 Claims. (Cl. 30-30) My invention relates to improvements in hair cutting and trimming devices.

The cutting and trimming of air as usually practised entails the use of a pair of scissors and a comb, the scissors being actuated by one hand while the comb is manipulated by the other hand of the operator.

it will be clear that if a. person endeavours to cut or trim his own hair it is with great difiiculty the act is accomplished and usually with indifierent results.

To overcome the difiiculties encountered I have contrived to associate a comb with a safety razor blade in such a manner that a person may cut or trim his own hair.

The arrangement of comb and razor blade is such that not only may hair be cut or trimmed but a graduated or shingle effect may be obtained.

Hair when properly cut should increase progressively in length from the neck and temples to the top of the head and an object of my invention is to be able to adjust the comb relatively to the razor blade so that my device wiil be adapted to meet all conditions encountered when cutting or trimming hair.

Another object is to prevent the razor blade edges coming in contact with the scalp, even when a close out is desired.

Another object is to assemble the comb relatively to the razor blade so that the device may be taken apart quickly and in a simple manner to permit stropping of the razor blade, if desired, or replacing it by a new one, and also make the combs available for cleaning.

Another object is to arrange the parts so that they are open to inspection at all times.

My device is such that it may be used not only by individuals but may be used with advantage in beauty parlours and in barber shops.

So that the nature of my invention will be clearly understood I have illustrated an embodiment of the same and described it in detail in the following specification in which:

Figure 1, is a plan view of part of the razor blade holder;

Figure 2, is a side elevation of the same;

Like characters of reference refer to like'parts in the several figures.

Referring to the drawings, 1 represents part of the holder of my improved hair cutter and trimmer formed at one end with a hand grip or shank 2, the other end 3, being flattened. The back or lower face of the fiattened end 3, is convex in cross section as shown at 4, while the upper face 5, is a flat or plane surface provided centrally with 'a longitudinally extending rib 6. Arranged in alignment with this rib but spaced therefrom is a small rib or projection '7 having undercut ends 8 and 9.

At the junction of the hand grip 2, and the fiat end 3, an elliptical ring 10, is slidably mounted and this ring is provided with a set screw 11 adapted to secure the ring in locked position as will be described hereafter.

A razor blade 12, of the safety type is mounted on the plane face 5, of the end 3, of the holder and the front portion of the blade is slid back to frictionally engage the undercut portion 9 of the projecting rib '7, and the central rib 6, extends through the usual elongated aperture in the razor blade. In this position the razor blade lies flat on the upper plane face 5, of the flat end 3, of the holder.

A razor blade clamping plate 13 is formed at one end with a slot 14 adapted to be slid along the projection 7, and the rear end 15, of the slot engages the undercut end 8, of the projection 7. The lower or inner face of the plate 13 is provided with an elongated recess 16 which engages the rib 6, on the end 3, of the holder.

The other end of the clamping plate 13, is provided with a short central nb 17, flanked by two ribs 18, from the latter of which extends two lateral hook projections 19, which are adapted to engage one end of the slidable elliptical locking ring 10.

The upper face 20, of the clamping plate 13, is convex in cross section and engages the under concave face 21, of the cover plate 22, which is formed at its front end with a depending elliptical ring 23, adapted to fit over the end of the flat portion 3, of the holder and its icoacting clamping plate 13.

The end of the cover plate 22, remote from the ring 23, is formed with a pair of longitudinally extending fingers 24, terminating in downward olfset ends 25, the fingers 24, being adapted to lit in the grooves formed between the

ribs

17, and 18, while the offset ends 25, overhang the edge of the clamping plate 13.

In this position the cover plate 22, the clamping plate 13, and the end 3, of the holder are held in assembled position by sliding the elliptical ring 10, into position over the fingers 24, and

ribs

17 and 18, whereupon the ring 10 is secured by the set screw 11.

The longitudinal edges 26, of the cover plate 22, project over the sides of the clamping plate 13, and below the lower face thereof and engage the edges of the razor blade 12, to deflect or bend the edges of the blade down- 3 wardly (see Fig. 14) and so place the cutting edges of the razor blade at the correct angle and in position to contact the hair being cut.

It will be seen that the holder, razor blade, clamping plate and cover plate are held firmly in place by thetwo rings 23 and and lateral displacement of any of these members cannot take place. Mounted on the cover plate 22, are two spacing blocks 27, having their upper and lower faces formed concave as shown at 28, and 29, the lower face snugly fitting and straddling the cover plate 22. The lateral faces 39, of each spacing block 27', slope outwardly and downwardly and are formed with a downwardly extending recess or channel 31.

The spacing blocks 27 are located in spaced relation adjacent the opposite ends of the cover plate 22.

Straddling the upper face of each spacing block is a strip of metal or other suitable material 32, which is shaped to snugly fit the upper concave face 28, of the spacing block and a bolt 33, passes through the cover plate 22, the spacing block 27 and the strip 32, to firmly hold them in position as an assembled unit. The ends 34- of the strip 32, are oliset downwardly forming arms spaced from, but in parallelism with the lateral faces 30, of the spacing blocks and the strip is fitted at each side with an adjusting screw 35, which is journalled in the strip but has its depending threaded shank 36, located in the recess or channel 31. The threaded shank 36, makes threaded engagement with the eyelet 37 which is formed with a radial pin 38, designed to be secured to the upper portion of the comb 39.

As each end of the comb is supported in this manner, the combs may be moved downwardly parallel with the ends 34 of the strip 32 or the combs may be tilted endwise. The teeth 49, of the comb normally extend slightly below the cutting edge of the razor blade 12, and both screws 35, may be rotated to project the comb into the desired position in which the teeth 40, will project below the cutting edge of the razor blade and so position the razor blade at the proper distance from the points of the comb teeth to permit the hair being cut to the desired length. In some cases it may be desirable or even necessary to adjust the comb by tilting it longitudinally so that one end of the comb projects farther below the razor blade than the other end and this is done by adjusting one screw to obtain the desired positioning of the comb. The device being double sided it may be manipulated with easeby either the right or left hand of the operator. When the device is in use the combs 39, are adjusted and the operator holds the device in his right or left hand depending on which side of the head the hair is being cut or trimmed. The operator now proceeds to move the device upwards from the neck thus giving this upward motion to the comb 39 which preceding the cutting edge of the razor blade 12 lifts or tilts the hair upwards against the natural lie of the hair, so that the hair comes in contact with the cutting edge of the razor blade and a clean cutting or trimming of the hair results.

As the operator proceeds with the cutting operation further up the head the combs 39 may be adjusted in the manner previously described so that the length of the hair will progressively increase towards the top of the head. The operator may give the device an upward curving motion and so obtain the graduation of hair cut desired.

If a very close hair cut is desired it is only necessary to adjust the combs 39 upwardly relatively to the razor blade 12 to obtain the required position of blade and comb.

It is believed that the construction and advantages of the structure shown may be apparent from the foregoing paragraphs taken in conjunction with the accompanying drawings without further detailed description.

While the preferred embodiment of the invention has been disclosed it is understood that minor changes in the construction, combination and arrangement of cooperating parts may be resorted to within the scope of what is claimed without departing from the spirit of the invention.
