Patented June 9, 1931 UNETED STATES ALEXANDER ADAIES, OF PHILADELPHIA, PENNSYLVANIA BARBEBS HAIR-CUTEING ISIAOI'IINE Application filed June 21,

My invention relates to barbers hair-cutting machines, commonly known as clippers, and applies to power driven clippers as well as hand operated clippers.

The objects of my invention are to provide a more efiicient machine than the type now in use; to increase the ease and rapidity of operation; and to add to the convenience of operator and customer. My invention is char- 1 acterized by the provision of an extending member at the base of the machine which acts as a fulcrum, enabling the operator to gradually and smoothly increase or decrease the length of the cut from one part of tne head or necl: to another and to cut with the clippers parts of the head which are commonly sheared with scissors. My invention is further characterized by the provision of a set of rollers on the aforementioned extending member which reduces the friction between the clipper and the skin of the customer.

While I am aware that hair-cutting machines have been designed with a prominent curve at the bottom front end of the casing to produce a heel or fulcrum about which the barber can swing the instrument whereby the hair can be cut at regularly increasing lengths from the neck up to the top of the head, my invention possesses certain ad vantages over such machines as will more fully appear from the detailed description which follows. The special means which I employ, combined with the other instrumentalities of this invention ano for the purpose as before premised, may be understood by reference to the illustrative embodiment shown in the accompanying drawings.

Of the drawings:

Big. I represents a side elevation of my improved instrument; and,

Fig. II shows a bottom view of the same.

In the drawings my invention is shown as applied to'an ordinary power driven clipper having a fiat casing 1, an upper cutter-plate 2, and a lower cutter-plate 3, carrying teeth of the desired coarseness, the upper teeth 8 moving transversely with respect to the lower teeth 9 to perform the hair-cutting operation. Extending downward and rearward from the lower cutter-plate, there is a curved project 1828. Serial No. 287,098.

ing member 4 which carries a pair of rollers 5, 6 for a purpose hereinafter to be explained. The cutter-plates 2, 3 are inclined in this instance at an angle of 45 to the longitudinal plane of the casing 1, this being a convenient inclination for the proper operation of the machine. At the rear end of the instrument there is shown a tubular sleeve 7 through whicn a flexible shaft furnishes the driving power to actuate the upper cutter-plate 2. A casing head 10 secured by a spring washer 11 and thumb screw 12 holds the upper cut ter-plate 2 firmly against the lower cutter plate 3.

For cuts of short length the roller 5 adj acent the cutter-plate 3 provides a frictionless wearing surface at the point of contact with the customers skin, Whereas for longer cuts the outer roller 6 provides a similarly frictionless heel about which the instrument can be guided to vary the length of the cut. The roller 5 is disposed slightly in advance of the bottom surface of the lower cutter plate 3, and accordingly the machine is particularly adapted to be balanced in two positions: in one position, to obtain relatively short cuts, the machine is held with the surface of the roller 5 and the lower cutter plate 3 in contact with the surface to be cut; and

in the other position, to obtain relatively long cuts, the machine is held with surfaces of both rollers 5 and 6 in contact with the surface to be out. With the instruments in common use, the constant rubbing of the clipper against the surface being cut, particularly when the latter is perspiring, is a source of irritation which inconveniences the customer, and with my improved instrument, not only is this difficulty obviated, but also the ease and rapidity of operation is increased to the satisfaction of the barber.

It will be apparent that, with the construcby the internal mechanism has little or no effect upon the heel of the instrument which is apart from the casing. It will also be observed that all parts of the instrument are accessible for easy cleaning and that the direction in which the rollers turn is such that the loose hair is cast off from the instrument.

While I have described my invention with some particularity, I desire it to be understood that sundry changes may be made in the form illustrated and described Without departing from the spirit of my invention as set forth in the appended claim.

Having thus described my invention, I claim:

In a barbers hair cutting machine, a casing, upper and lower cutter plates at the head of said casing and inclined to the plane thereof, a curved projection extending downwardly and rearwardly from the casing adjacent said lower cutter plate, and a pair of rollers on said projection, said rollers being so disposed with respect to the plane of the lower cutter plate whereby a relatively short cut may be obtained by using one of said rollers and said lower cutter plate as surfaces of contact, and whereby a relatively long cut may be obtained by using both rollers as surfaces of contact. a

In testimony whereof,- I have hereunto signed my name at Philadelphia, Pennsylvania, this 16th day of June, 1928.

ALEXANDER ADAMS.
