HAIR-CUTTING APPLIANCE.

Application filed February 3, 1919.

To all whom it may concern Be it known that I, SAMUEL SEVERSON, a citizen of the United States, residing at Valders, in the county of Manitowoc and State of Wisconsin, have invented certain new and useful Improvements in Hair-Cutting Appliances, of which the following is a specification.

The present invention relates to improvements in hair-cutting appliances, and particularly to that type embodying motor driven cutting instrumentalities. The primary object of my invention is to provide a device of this character so constructed as to facilitate the operation of trimming hair to any desired length, and for this purpose involves means performing the function of a gage enabling the operator to readily vary the length of cutting during manipulation of the appliance. To this end this particular gage feature of the device is so arranged as to yields-to pressure when the operator applies the apparatus in order to bringthe cutting element into closer relation to the surface over which it is moved, thus effecting close cutting action, while on the other hand allowing said elements to be retracted from such close position to produce a greater cutting length of the hair, the variable adjustment between the shortest and longest hair length being automatic so to speak.

A further object in view is to provide a variable adjustment of the gage so as to predetermine the maximum length of the hair for which the instrument is set to suit the particular case.

A still further object resides in the provision of suction producing: means whereby to draw the hair into proper position with respect to the cutting blades and to dispose of said hair after being cut, all as hereinafter set forth.

Other objects and advantages as may hereinafter appear are attained by the novel construction, combination and arrangement of parts to be hereinafter specifically described and'claimed.

Reference will now be had to the accompanying'drawings forming a part of this specification, wherein:

looking at that side which is oppbsite to the side shown in Fig. 1;

Fig. 3 is a bottom plan, or an end elevation of the end of the appliance at which cutt ng instrumentalities are disposed;

Fig. 4 1s a vertical sectional view;

Fig. 5 is a similar view taken on the line 5-5 of Fig. 4; and

Fig. 6 is a horizontal sectional view on the line 66 of Fig. 5.

Referringto the drawings and specifically describing the present embodiment of the invention, it may be stated that the appliance consists of an inner casing 1, in which the cutting instrumentalities hereinafter referred to are mounted, and of an outer casing 2 which really constitutes a handle by means of which the apparatus is manipulated. The inner casing comprises a removable cover plate 3 secured in place by means of fastening elements or screws 4, said cover plate havingits lower end bent inwardly as shown in Fig. 5 most clearly to form what I call a baffle, or deflecting flange, designated 5. The function of the bent end will be brought out at a later point. Secured to the inner wall of the casing at its lower extremity is a stationary cutting blade 6 having a series of V-shaped teeth of conventional form and mounted within the casing upon the pivot 7 is a cutter bar 8 cooperating at its lower extremity with the movable cutter blade 9 similarly provided with teeth which are held in close relation to the teeth of the blade 6 by means of a spring 10 mounted upon a projection or pin 11 attached to the bar 8. This spring bears against a pair'o f upturned ears 12 on the movable cutter blade. The movable blade just'referred to is reciprocated in the present instance by means of the eccentric cam 13 carried by the end of the flexible shaft 14 which is driven from a suitable motor (not shown), said cam being disposed between the bifurcate extremities 8 of the cutter bar 8. It is to be understood, of course, that any other suitable means might readily be employed forimparting reciprocation to the cutter element but for the purposes of this device that which is herein disclosed is sufficient to carry out the object of my invention.

The outer casing or handle 2 mentioned above is open at one side as shown in Figs. 1 and 6, the edges of the material being bent to provide the flanges 15 forming guide means for the adjustable and movable gage element which is now to be described. It should first be mentioned, perhaps, that the outer casing or handle 2 is attached to the inner casin 1 at one end by means of the nuts 16 which are carried by threaded projections 17 extending from the inner cas' ing through the closed end of the outer casing.

The gage device which I employ is of special construction, being in the form of a rectangular sleeve designated 18 which is slidably received between the outer and inner casings 1 and 2. The lower end of said sleeve projects from the appliance and is provided with the surface contacting edges 19 which are adapted to be moved over the surface from which the hair is to be cut. The sleeve'is arran ed. to be moved inwardly -and outwardly of tie casing for the purpose of determining the position of the cutting instrumentalities with respect to the surface against which the flanges 19 bear so as to produce the variable length of cut of the hair as desired. In other words this sleeve 18 has connected thereto an elastic member 20, the end of which is preferably attached to' the upper end of the sleeve by bending a portion of the material outwardly and back against at 21 to form a clamp. The elastic passes about a roller bearing 22 mounted at the lower end of the outer casing which is also formed with a slot extending longitudinally at this side, as indicated at 23. The opposite end of said elastic is connected to a cross pin 24;, which is detachably received in a seat at the upper end of the slot in the outer casing as clearly shown in Fig. 5. This elastic constitutes a tension device normally tending to project the sleeve from the casing and the amount of projection under the'tension of the elastic 1s predetermined by the adjustable stop member 25 which is 'slidably mounted in the slot 23 and frictionally engaged with the edges of said slot so as to stay at a predetermined adjustment. The outwardly bent portion of the sleeve designated 21 is adapted to coact with this stop 25 in order to limit the outward move- I ment of the sleeve and obviously-when it is desired that the sleeve shall not project as far as disclosed in Fi 5 in full lines, the stop 25 would be ad usted at a position nearer the top of the appliance. But to permit the sleeve to project'farther, to the extent shown in the dotted lines in said figure, the stop 25 would be moved downwardly to the dotted line position of said fi ure. The sleeve, it is understood, is yielda le responsive to the pressure of the applithe surface and this will bring,

ance against according to the extent of inward movement of the sleeve, the cutting elements into closer the body of the sleeve as indicated as to ,change relation to the surface against which the flanges 19 are pressed. When the pressure is relieved the sleeve moves outwardly and necessarily the cutting elements are retracted or move away from the surface so that the gaging of the length of out of the hair is really determined quite readily by the operator by the amount of-pressure which is exerted on the body of the appliance and which causes the relative movement of the guide sleeve in the manner just described.

For the purposes of bringing the hair in such position with respect to the cutting blades, as to facilitate the cutting of said hair, I preferably employ suction or vacuum producing means (not shown), connecting said means with the inner casing through the tube 26, extending to the opening 27 in the inner casing 1. Under the action of the suction the hair will be raised by the current of air passing into the lower end of the sleeve so as to stand up between the blade members 6 and 7. By reason of the position of the deflecting flange 5 on the casin cover 3 which causes the air to pass into t e casing in a transverse direction of the blades it will be obvious that the hair will be brought into the cutting position above referred to most effectively. The severed hair passes in the usual manner through the casing and the tube 26 to the vacuum apparatus where it is taken care of in the usual manner.

Briefly summing up, the operator in the use of this apparatus manipulates the same by grasping the handle or outer casing 2 and starting at a point where the hair is to be cut short, pressure is exerted against saidhandle to move the sleeve 18 inwardly, to thereby bring the blades 6 and 7 close to the scalp. Moving the appliance upwardly over the top of the head said pressure is gradually released, accompanied by an extension of the sleeve outwardly of the casing, the blades being consequently retracted from the closer position referred to until the maximum extension is reached, corresponding to the part ofthe scalp where the hair is allowed to remain relatively long. As before indicated, if it is desired to adjust the device so this limit to a point which will represent a greater length of hair, the operator has only to slide the stop 25 downwardly in its'slot whereupon it will allow a greater amount of extension of the sleeve before its stop portion 21 will contact with the stop 25 referred to. Any variation of the length of cut of the hair is obtainable within reasonable range simply by the control of the pressure which the operator uses and which effects the position of the sleeve 18.

Having thus described my invention, what I claim as new is:

1. A hair cutting appllance of the classdescribed comprising a body provided at one side with guide means, cutting instrumentalities mounted upon said body, a gage member yieldably mounted for movement into and out of the body to regulate the out of the hair, tension means normally tending to project the gage member from the body, and a slide adjustably mounted in the guide means aforesaid and movable longitudinally of the body, said slide being arranged to be impinged by the gage member to limit the extension movement of the latter.
