Ruggierl, Ventura, Calif., , and one-fourth to Johanna M. ‘Wargin, Hu eneme, Calif. Substituted for abandoned application Serial No. 518,206, February 25, 1931. This application April 5, 1937, Serial No. 135,182 6 Claims. The invention relates to electric hair cutters, and has for an object to present a hair cutter of small size, in a form adapted to be conveniently manipulated by one hand with a minimum of ef 5 fort and without requiring the holding or move ment of the device in positions awkward for the operator. It is an aim to present a novelconstruc tion in the ‘device to enable its more certain manipulation and accurate cutting action. 10 ' A further important aim is to effect improve ~ ‘ ments in the construction and arrangement of the (Cl. 30-210) of a frame piece 20, which may also be extended outwardly from the case and shaped to form the toothed ?nger bar 23, presently to be described. The body of the frame piece is offset inwardly, from the shank 2| in symmetrical relation to the handle. The frame piece is formed with a cutter side smoothly ground to true longitudinal rectilinear surfaces. Centrally and longitudinally of this face there is formed a groove 22' extending for 10 full length of the body portion and spaced in parts in such a device. It is a speci?c aim to en ward from the inner face of the shank 2| a dis tance. At one side of this groove thebody of the frame is shaped as a ?nger bar 23 with ?ngers 15 ment.‘ Another object is to enable the removal of 24' extended at right angles to the groove, and the respective blades for cleaning, adjustment and ' each having a plane surface coincident with that sharpening. of the adjacent top face portions of the bar. At Additional objects, advantages and features of the opposite side of the groove the bar is extend invention reside in the construction, arrangement ed in a suitable shape for purposes to be de 20 and combination of parts involved in the em scribed, but limited as much as practicable in 20 bodiment of the invention, as will be more readily order that the weight and bulk of the portion understood from the following description and which is moved adjacent the head of a person will accompanying drawing, in which: be a minimum. The outer longitudinal edge of Fig. 1 is a longitudinal sectional view of the the bar 23 at the side is ?tted with two removable able the quick dismounting of the various parts without requiring complicated’ 'tools or equip ' cutter,‘ . ' prongs 24 of considerable length, adapted for _' Fig. 2 is a transverse section through the as sembled device showing the structure and rela tion of the tension or retainer plate to the cutter bars and teeth thereof as well as the guiding 30 prongs 24, ' Fig. 3 is a detail of the reciprocating cutter removed, a Fig. 4 is a rear view of the appliance, Fig. 5 is a front end view thereof. 35 I There is illustrated a hair cutter comprising a case ‘Ill adapted to form a handle for the appli ance, the rear body portion of the case being cy lindrical, and having a forward portion tapered to an oblong shape in cross section at its ex 40 tremity. The rear end of the case is closed by a screw cap or bushing 12 preferably formed of in “sulatlng material so that electric wires may be various uses in manipulating the device for cut ting the hair of a person, and particularly in indicating the angle at which the plane of the cutter is disposed with respect to the adjacent contour of the head. These may also be rested 30’ against the head or neck of the person to steady the cutter as it is moved forward in cutting the hair. Also, while the handle is grasped in one part of the hand, a ?nger or fingers may be ex- ' tended to rest on the project from one or both prongs toward the head of the person whose hair is being cut, to regulate the length of the hair left uncut upon the head. It is also contemplated that the ends of the spurs shall be rested against the neck or head of 40 the person whose hair is being cut and used as both a rest and a lever to move the cutter out led therethrough safely to the electromagnetic ward from the head progressively as the cutter motor of the device. Secured in the cylindrical portion of the case H! l’ there is an electromagnet l3 comprising a core is moved forward in operation. This leverage is effected by adjusting the prongs flat against the lower neck portion of the person and then by piece It having two spaced apart cross channels I5 therein of suitable dimensions to receive a ' coil of adequate size. The core thus has a central 50 ?eld piece It and two outer end field pieces IT. The coils 18 of the magnet are energized by wires l9 from a suitable source led through the bushing l2 as shown. The core piece is centrally grooved across its outer side longitudinally of the 66 case, and set in the groove there is the shank 2| twisting the handle so as to cause the tips of the prongs to press against the person, the bar is lifted away from the scalp. This twisting referred to is such as to rotate the handle on its longi 50 tudinal axis, it will be understood. By making this twisting progressive as the cutter is moved upwardly, the proper "shingle” of the hair as de sired may be accomplished. A cutter bar 26, is provided, of a suitable form 55 2 complementary to the ?nger bar, in accordance edge of the ?nger-bar adapted to rest against the with familiar practice in the manufacture of ‘head and to receive the ?nger of an operator clippers generally. Its rear edge is formed‘ with against the side thereof for the purpose described. 2. In a hair cutting appliance including a ?n a rib or ?ange 21 adapted to fit snugly ‘and slid ger-bar, a longitudinally reciprocable cutter co ably in the groove 22', and the bar 26 'is'extend ed inwardly into the case a distance as a plate 28 operatively associated therewith, a bell crank lever on which the rib 21 is continued. Near the inner mounted to pivot at its middle in the plane of the ,end of the bar 26 a lateral rearwardly extending arms of the lever and provided with an arm arm 29 is formed therein, stopping short of the ‘initially transverse to the cutter and connected side of the case Ill. The adjacent faces of the at its extremity to the cutter, said’ lever having a 10 frame are smoothly ?nished in a common plane second arm extended longitudinally of and away on both sides of the groove, so that the bar and arm 29 may slide smoothly thereon. A lever 30 is laid on the plate 28 and arm 29 to oscillate 15 thereon. This lever has a longitudinally slotted extremity, receiving therein a pin 3| carried on from the cutter and having an armature thereon I oscillatable transversely to the longitudinal axis ‘of thecutter and an electromagnet operatively associated with‘ the armature. . 15 3. The structure of claim 2 in which said 943- - - the end of the arm 29. This lever extends across pliance has a handle enclosing the lever and inner the frame to near the far side of the case; where part- of the cutter and the'second named arm of it is ?xed on an armature 33 disposed in operative the lever is extended longitudinally in the handle, 20 relation to the electromagnet l3. A leaf spring the electromagnet being in the handle laterally 20 34 is also secured as by rivets 32 to the armature .beside the said second named arm and armature. under this lever, its opposite end being secured to 4. The structure of claim 2 having a longitudi the magnet, yieldable to theforce of the ?eld of nal hollow handle, and in which the cutter is the magnet in attracting the armature when the formed with a lateral extension of its inner part magnet is energized. This spring serves as the within the 'handle, the extremity of the ?rst 25 mounting of the armature and serves to cause named arm of the lever being pivoted to the ex it to pivot thereon. ~ . A retainer plate 35 is loosely engaged over the cutter and lever in‘spaced relation to the ?nger 30 bar, this plate having a ?ange 36 at its forward edge, engages in a groove formed in the outer face of the cutter, and the plate 35 has at its rear edge an inner ?ange 38 resting against the ?ange piece and ?nger bar at the rear edge. Retaining 35 screws 39 are engaged through the plate 35 ‘and in the frame piece, small helical springs 40 being engaged therearound and confined between the plate 35 and the frame piece. By this means the . cutter maybe held securely in proper operative 40 relation to the ?nger bar and the springs will prevent binding of the cover plate on the cutter. In operatiomthe current supplied through the _ wires l9 may be taken from any suitable source of alternating or intermittent current supply. 45 The armature 33 and spring 34 may be so pro portioned as t‘drespond to normal alterations of current in a 60 cycle supply, or the circuit may include an interrupter of lower frequency of in termission. When the magnet I3 is energized the 50 attraction and movement of the armature causes the lever 30 to swing longitudinally outward and bearing on the pivot 3|, the‘cutter-bar is moved ' correspondingly outward. As soon as the current ceases or reverses, the spring forces the armature 55 outward, producing a reverse movement of the All moving parts may be re moved by drawing the screws holding the cover plate and removing the latter. The prongs 24 are of su?icient length ,to project through or from ‘lever and cutter. 60 under a mass of hair, in case it overlies the cutter, so that the ?nger bar may be held in proper plane with relation, to the head from which hair is being cut. .
