GRADUAT ING HAIR I CLIPPER Filed Oct. 8, 1932 Patented July 7, 1936 STATES PATENT OFFICE 4 Claims.

My invention relates to improvements in :graduating hair clippers and it has for its object to improve the construction and. mode of operation thereof.

It is also an object of this invention to simplify and improve the operation of graduated hair cutting to the end that the hair may be cut expeditiously in a uniform and accurate manner.-

To these ends I have provided an improved hair clipper having certain novel features of construction and mode of operation set forth in the following description, the several novel features being particularly pointed out and defined in the claims at the close thereof In the accompanying drawing: 7

Figure 1 is a side elevation of a hair clipper constructed in accordance with this invention.

Figure 2 is a bottom plan view of the bottom plate hereinafter described showing the parts in separated relationship.

Figure 3 is a front elevation of the clipper shown in Figure 1. V

The embodiment of my invention herein illustrated comprises a bottom plate consisting of two sections, l and 2, the former being provided with a rigid handle l The instrument is also provided with a complementary handle member II which is pivotally supported by the bottom plate section I and which, when vibrated, serves to reciprocate a cutting comb l6, as usual.

As shown in Figure 2 the bottom plate section 2 is constructed as a comb which is held against the head of the subject.

The forward comb element or section 2 of the bottom plate is provided with a pair of rearwardly extending rods 2 which are slidably mounted within holes l provided in bottom section I. The bottom face of section I is fiat and the rods 4 are parallel therewith. The rear end portions of the holes within which the rods are mounted are threaded interiorly to receive adjustable stop screws I These stop screws may be set for engagement with the inner ends of the rods thereby to limit the extent of movement of section 2 toward the section I; That is, the stop screws may be set so as to position section 2 relatively to cutting comb I6 when said section 2 is at the limit of its inward movement.

Secured in position upon the rear section I of the bottom plate by means of a threaded stem l2 and wing nut I3 is a sheet metal cap 3 whose lower front end edge portion ll bears against the top of the cutting comb l6 and holds the latter against upward displacement as said comb is reciprocated. The top portion of bottom section I consistsof an intermediate cutting comb plate I i that is a rigid part of section I and against the top of which the opposite side walls of the cover 3 are fitted.

Projecting from one of the side walls of cover 3 is a stud 3 on which is loosely mounted a pulley t to which one end of a'fie'xible cable I is fastened. The opposite end of cable 1 may be provided with a ring I5 for engagement with a fixture, or which I0 may be held by one hand of the user of the clipper while he employs the other hand to operate and control the latter.

One end of a link 5 is pivotally connected at 4 to the inner face of pulley 4, while the opposite end of said link is pivotally fastened by a connector 9 to one arm of a lever B that is pivotally connected by a fulcrum screw III to the adjac'ent side wall o'f cover -3. The leverilmay'be a bail-shaped structure which embraces the cover 3 as shown in Fig. 3, the oppositely disposed legs or arms thereof being pivotally connected to opposite sides of cover 3 as described.

One end of a link 6 is pivotally connected at 2 to one side of the section 2 of the bottom plate while the opposite end of said link 6 is pivotally fastened by a connector 9 to one of the arms of lever 8.

Each cutting stroke of the clipper is started with the bottom comb element or section 2 in its retracted position and as the clipper is moved forward the operator restrains or holds back upon the cord or cable '5 which acts through the motion transmitting gearing including pulley 4;, link 5, lever B and link 6 to gradually advance the bottom section 2 relatively to the cutting comb It with the result that the cutting action is graduated so that the clipper cuts shortest at the start and is gradually adjusted away from the head by section 2 as the clipper is moved for- 40 ward.

I am aware that graduating clippers have heretofore been provided having a bottom plate that was manually advanced during each cutting stroke of the clipper, but it is a distinguishing feature of advantage to the above described construction that the flexible cable 1 which is manipulated by one hand of the operator, permits the latter to fully control and manipulate the instrument with his other hand without interference by the flexible cable I, the pull upon said cable during the forward stroke of the clipper having no other appreciable effect than to advance the section 2 of the bottom plate thus leaving the instrument 55 free to be guided and moved about by the other hand of the user both laterally and back and forth.

Preferably the lever 8 is formed with a slot 8* within which the connector device 9 is fixed with provision for adjustment lengthwise of said slot when desired. Also the connector device 9 is preferably fixed Within a slot 8 formed in lever B with provision for adjustment lengthwise thereof when desired.

A series of holes 8 formed in lever B provides for vertical adjustment of the latter and I may also provide the pulley 4 with a plurality of angularly spaced apart holes 4 for reception of the pivotal connector device 4'.

The arm of lever 8 with which the links 5 and 6 are connected is also formed with a third slot 8 disposed above the fulcrum ill of said arm and this slot is provided to permit of dispensing with pulley 4 and link 5 in which case the connector 9 may be transferred to the slot 8 and the end of cable I connected therewith. Or, if the pulley and link are dispensed with, the end of the cable 1 may be merely tied to the lever 8 at the slot 8.

Of course it is possible to control the gauging section 2 of the bottom plate by direct manipulation of lever 8, but the objection thereto is that such direct manual control interferes, to a material extent, with the proper manipulation of the instrument by the other hand of the operator.

If desired the cable I may be made sufficiently long to permit the ring I 5 to be engaged with a fixture at the rear of the barbers chair so that the clipper instrument can be carried about from one side of the chair to the other, the barber holding the cable 1 intermediate its ends while performing the cutting operations.

What I claim is:

1. A clipper of the character described constructed with a bottom plate consisting of a rear section and a front section, said front section being slidably associated with said rear section; a handle member rigidly connected with said rear section; a lever carried by said rear section; a pulley rotatably supported by said rear section; a link connecting said pulley and lever; a link connecting said lever with said front section, and a flexible cable having one end thereof connected with said pulley and manually operable during a cutting stroke of the instrument to cause said pulley, lever and links to advance said front section thereby to graduate the length of the cut hair.

2. A clipper of the character described constructed in accordance with claim 1, wherein said lever is formed with an approximately radial slot and including a connector adjustably fixed within said slot by which one end of said first-mentioned link is connected with said lever, said connector being adjustable lengthwise of said slot to vary the extent of movement of said front section.

3. A clipper of the character described constructed in accordance with claim 1, wherein said lever is formed with an approximately radial slot and including a connector adjustably mounted in said slot by which one end of said last-mentioned link is connected with said lever, said connector being adjustable lengthwise of said slot to vary the extent of movement of said front section.

4. A clipper of the character described constructed in accordance with claim 1, wherein said pulley and said first-mentioned link are removable and wherein said lever is formed with a means for use in connecting one end of said cable directly to said lever so that tension on said cable will operate the lever to advance said front section during a cutting stroke of the instrument.
