Specification of Letters Patent.

Patented Oct. 12, 1920.

Application filed May 20, 1920. Serial No. 382,780.

To all whom it may concern:

Be it known that I, EUGENE S. CARLSEN, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hair Clippers, of which the following is a specification.

This invention relates to improvements in an individual or adjustable hair clipping or cutting device, or in other words, to improvements in that type of hair clippers or cutters which are more particularly intended for use by a person in the operation of cutting or clipping his own hair.

The invention has for its main object to furnish a hair clipper or cutter device which shall be simple and inexpensive in construction, strong, durable and efiicient in operation, with its parts so made, arranged and cooperating with one another as to enable the cutting members or knives to be adjusted or turned to either side of the handles thereof, and there fixed in the proper position, to the end, that the instrument can be used by either hand of the individual in cutting his own hair, and in such a way that the rounded or smooth surface of the supporting body of the device will be presented to the head in the operation thereof.

Other objects and advantages of the invention will be set forth in the following description and explanation.

The invention consists in certain peculiarities of the construction, novel arrangement and operation of the various parts thereof as will be hereinafter more fully set forth and specifically claimed.

In the accompanying drawing, which serves to illustrate an embodiment of the invention- Figure 1 is a plan view of the device with its parts in their normal positions when used by the left hand of the operator in cutting his hair on the left hand side of his head.

Fig. 2 is an edge view thereof looking toward the cutting edge of the instrument.

Fig. 3 is a cross-sectional view taken on line 3-3 of Fig. 1 looking in the direction indicated by the arrows.

Fig. 4 is a view looking at the front end of the device when the parts are positioned as shown in Fig. 1, and

Fig. 5 is a plan sectional view taken on line 5-5 of Fig. 3 as indicated by the ar-.

rows.

Like numerals of'reference refer to corresponding parts throughout the different views of the drawing.

The reference numeral '7 designates the base or body carrying handle of the clipper, which is slightly curved from the other handle 8 thereof and is provided on its outwardly bowed portion at about the middle thereof with a thumb-guard 9 which is forked as shown in Figs. 1, 2 and 4 of the drawing for the purpose of receiving be tween said forks or prongs the thumb of the hand in which the instrument is held when being used. The other handle 8 is provided on its outer portion with a projection 10 to assist in gripping the handle, members, for

it will be understood that the fingers will grasp the handle 8 while the thumb engages the guard 9 on the outer surface of the first named handle.

The handle 7 is provided at its front portion with a lateral extension 11 which is located rearwardly of the front end of said handle as is shown in Fig. land is provided transversely with an opening through which is extended a plunger or rod 12 which has mounted on its rear end, preferably by being screwed thereon, a head 13 which is provided in its rear end with a pair of spaced apart projections 14 between which is located a cam extension 15 extended from the front end of the handle 8, which handle is pivotally connected to the handle 7 by a pivot 16 near the rear end of the supporting body 17 as is clearly shown in Figs. 1 and 2 of the drawing.

The front end of the plunger or rod 12 is providedwith a pair of prongs 18 between which "1s located a stud 19 extended at a right angle from a member or plate 20 which is pivotally mounted on the cylindri cal portion 21 of a projection 22 extended from the base 23 of a segmentalplate 24 which is providedwith an arcuate slot 25 through which is extended a set-screw 26 which engages a suitable opening in the handle member 7 near the extension "11 thereon but in its opposite surface.

The forward'extension 27 of the handle member 7 or that portion of said member in front of the lateral extension 11 is pivotally secured to the plate 24 by means of a screw or suitable pivot 28, see Fig. 3, just above the base 23 of said plate, and the front end of the extension 27 is by preference rounded or of such length forwardly of the pivot 28 to permit of the relative rotary movements of the handle members and the supporting body 17 in order that the parts may be changed from the positions shown by continuous lines in Fig. 2 of the drawing to that shown by dotted lines in said figure, which change of positions will adapt the de vice to be used in the right hand of the oper ator in clipping or cutting the hair on the right hand side of his head. The stud 19, which as before stated is extended between the prongs 18 of the plunger rod 12 is provided near its free end with a transverse opening 29 which as shown in Fig. 3 is flared at each of its ends to permit of a slight lateral movement of the prongs 18 of the plunger or rod 12, which prongs are secured to the stud 19 by means of a pin 8t extended transversely thereof and through the opening 29 in said stud. That end of the member 20 opposite the stud 19 thereon v is provided with .an extension 31 which engages a recess 32 in the inner edge of the reciprocating cutter-bar 33, which bar is slidably mounted on the flat and inner surface of the supporting body 17, which body has its outer surface rounded cross-sectionally as shown in Figs. 3 and 4 of the drawing. The bar 33 is provided at its outer edge with spaced knives or cutters 34 which co-act with similar knives or cutters 35 on the corresponding edge of the body 17. This latter bar is provided with a longitudinal slot 36, see Fig. 5, through which extend studs 37 mounted on the supporting body 17 and extended from the flat or'inner surface thereof. By this arrangement it is apparent that the reciprocating bar 33 will be guided by means of the slot 36 and the pins or studs 37 for back and forth movementon the supporting body.

In order to hold the reciprocating cutterbar 33 in position on the body 17 the latter is provided at a point about the longitudinal middle thereof with an opening 38 which registers with the slot 36 and is for the re ception of a screw 39 which extends through the slot 36 and through a suitable opening in a keeper-bar 40 which is longitudinally channeled to receive a correspondingly extended rib on the upper surfaceof the bar 33, which construction will further provide a guiding means .for the back and forth movement of the reciprocating cutter-bar.

' The keeper-bar 40 is provided with a pair of openings 41 to receive the studs 37 and thus prevent any movement of said bar.

Mounted on the inner or upper end of the screw 39 is a milled nut 42 by means of which the keeper-bar is held in position.

Located between the extension 11 on the handle member 7 and the head 13 on the plunger or rod 12 and surrounding the same is a spring 43which has one of its end in engagement with the extension 11 and the other in engagement with the head 13,.and

ator by simply placing the thumb of said hand outwardly of the member 7 and between the prongs 9 of the thumb guard and by placing the fingers of said hand outwardly of the handle 8 and astride the projection 10 thereon when it is obvious that the rounded surface of the supporting body 17 can be placed against the neck or head of the user with the cutters or knives extended upwardly, when by intermittently gripping and releasing the handle members 7 and 8 the reciprocating cuttenbar 33 will, through said gripping action and the instrumentality of the spring 43, be moved back and forth on the supporting body 17 7 ters35 in clipping or cutting the hair interposed between the same.

Now, when it is desired to adjust the body with respect to the handle members, for use in the right hand of the operator, all that is necessary is to loosen the set-screw 26 and turn the supporting body 17 from the posi tion shown by continuous lines to that shown by dotted lines in Fig. 2 of the drawing when it is obvious that the cutting members on the supporting bar will be presented upwardly but at the opposite sides of'the handle'members. As it' may be. desirable, sometimes to set the cutting members at an angle to the handle members, instead of in parallelism therewith as shown, the face of the plate adjacent the head of the screw 26.

porting body rigidly mounted on said plate at right angles thereto, a cutter carrying bar slidably mounted on said'supporting body, a member pivotally mounted between said plate and body and engagingsaid cutter carrying bar, another handle member pivoted to the first named handle member and having an extension at its front end, a springactuated plunger slidably mounted on said lateral extension and operatively engaging at its rear end the extension of the last named handle member, means loosely con necting the front portion of the plunger with said pivoted member, and a set-screw extended through the arcuate slot and engaging the front portion of the first named handle member.

2. In a hair clipper, the combination with a handle member having a lateral extension near its front end, of a plate mounted on the front portion of said member for rotation in a plane parallel therewith, a cutter carrying supporting body rigidly mounted on said plate at right angles thereto, a cutter carrying bar slidably mounted on said supporting body, a member pivotally mounted between said plate and body and engaging said cutter carrying bar, another handle member pivoted to the first named handle member and having an extension at its front end, a spring-actuated plunger slidably mounted on said lateral extension and operatively engaging at its rear end the extension of the last named handle member, and means loosely connecting the front portion of the plunger with said pivoted member.

3. In a hair clipper, the combination with a handle member having near its front end a lateral extension provided with an opening and said member having forwardly of said lateral extension a longitudinal, extension provided with a transverse opening, of another handle member pivoted to the first named member and having at its front end a cam extension, a spring-actuated plunger movably located in the opening of said lateral extension and-operatively engaging at its rear portion said cam extension, a plate rotatably mounted on the longitudinal extension and having an arcuate slot near its periphery and provided with a base at an angle thereto, said base having a projection opposed to the plate, a supporting body fixed on said projection and having knives or cut ters at one of its side edges, a reciprocatory cutter carrying bar mounted on the said body and having a recess in one of its edges, a member pivotally mounted on said proj ection and having an extension engaging said recess, said member having a stud in loose connection with the front portion of said plunger, and a set-screw extended through the slot of the rotatable plate and engaging the first named handle member.
