CLIPPER .A Application med July l99, 1929. seriai No. 381,989.
`This invention relates toa hand operated clipper especially designed'V and adapted forv removing the hair under the arm pits.
f For various reasons,j1t 1s desirable to use (6 hair'clippers'V for the purpose of removing Y because the known clippers are so constructed .10 and so operated as to be incapable of following the contour of the flesh inthe region'of the armpits and also becauseall prior types of clippers are designed'forj-use with one hand only. Concerning the latter feature of the prior types of hand clippersit is to be noted that such clippers have a stationary handle and a* movable handle. Thi-s arrangement makes it possible to operate the clippers with one hand only and if suoha clipper is shifted A to the other hand it will be found practically impossible to effectively use the clipper for the reason that the clipperrmay not'be held steady while operated. y
Among the importantobjects of the pre-s.-l ent invention are to provide a hand operated clipper which is adapted for convenient and effective. operation kwithj ,either hand and which is so constructed and organized that it readily and easilyv follows the contour ofthe flesh in the region of the arm pits and does so in such'a manner as to effect very close clipping of the hair without any pulling and without any abrading or irritating action on the liesh.
clipper is provided which consists broadly of coacting blades mounted on vone end of a handle memberin such manner that when ,4 the clipper is in use it operates with a hoe Y Y in the conventional clippers. This feature is one of the principalfactors inthe ability of the clipperV to follow the contour ofthe flesh in the region of the arm pits and to effec-V tively remove or clip hair in such regions. In
. addition the operating mechanism provided for the clipper blades, the manner of its or- In carrying outithe present invention a hair c ganization with the handle and with the blade, is such as to provide for easy and convenient .operation of the clipper with either hand.
Other objects and advantages reside in eertain novel features of the construction, arrangement and combination of parts which will be hereinafter' more fully described and particularly pointed out in the appended claims, reference being had to the accom- .panying drawing forming a part of this speciiication, and in which:
Figure l is a view in front elevation showing a hand operated clipper embodying the present invention;
Figure 2 is a view in section on line 2 2 of Figure l, parts being shown in'elevation for the sake of simplicity and illustration;
Figure 3 is a top plan view of the clipper, parts being broken away and parts being shown in section for the sake of illustration; and
Figure 4 is a view in horizontal section taken on line 4 4 of `Figure 2.
Referring to the drawing, numeral l designates generally a handle which includes an outer part or casing 2 shaped to be conveniently gripped in the hand and having titted'and releasably secured by means of a lock screw 5. The shank 4 projects above the upper end of the casing or covering 2 and hasv a reduced extension or post ,64 formed integral therewith.
On this post 6 a fixed blade 7 anda coacting movable blade 8 are mounted. The fixed blade 7 has an internally threaded opening 7 therein and with this internally threaded opening 7 the threaded outer end 5 of the a. socket 3 in which a shank 4 is frictionally i --L- Ajsleeve '12 is ifitted 1ontheJi-ifine'r.smooth,y portion of the post 6 for oscillating movementv mit thecmovable blade tohave the requisite l freedomjofgmovementi ffAlong itSrear edge;y

Along with these advantages the clipper is simple and of durable construction, its parts are easily accessible for cleaning and lubrication, replacement and repair and it lends itself to economical manufacture by facilities and from materials ordinarily obtainable. While a clipper embodying the present invention is especially designed and adapted for removing hair under the arm pit, in general this clipper may be used to advantage in places where a regular standard type of hand clipper may not be effectively or satisfactorily employed.
rEhe invention claimed is:
l. A hand operated hair clipper comprising a handle having a main portion, coacting blades mounted on one end of the handle and arranged transversely and at right angles thereto whereby the blades are adapted to be advanced during cutting with a downward ulling motion and operating means for the blades including an oscillatory sleeve intermediate the blades and the main portion ofA the han-dle, means connecting said sleeve to one of the blades -and means on said sleeve adapted to be grasped between the thumb and forcfinger of the same hand that grasps the handle. f
2. A hand operated clipper comprising a handle, a fixed blade extending transversely to the handle and secured thereto adjacent one end thereof, a movable blade coacting with the fixed blade, a tension member mounted on the handle, means for forcing the tension member against the fixed blade and for biasing it to bear against the movable blade to cause the movable blade to engage the fixed blade with the proper tension and means mounted on the handle for operating v the movable blade.
3. A hand operated clipper comprising a handle, a separate fixed blade extending transversely of the handle and secured there to near one end thereof, a separate movable blade coacting with the fixed blade, a sleeve mounted for oscillation on the handle and a driving member secured to the movable blade and interconnected with the sleeve so as to be oscillated thereby.
4. A hand operated clipper comprising a handle, a fixed blade secured to the handle near one end, a movable bladecoacting with the fixed blade, a tensioning member for urging the blades to engage each other with the proper pressure, a sectional housing secured to the fixed blade and enclosing the fixed and movable blades and the tension member and operating mechanism for the movable blade including a sleeve mounted on the handle outside of the housing` and having a portion projecting therein and a driving connection between said portion and the movable blade.
5. A hand operated clipper comprising a handle having a post extending axially from one end thereof, a blade fixed to one end of the post and extending transversely thereto, a sleeve rotatable on the post, a driving member connected to the sleeve, a movable blade secured to the driving member and coacting with the fixed blade, and a spring tension member fixed to the post and bearing up against the movable blade to urge it to engage the fixed blade with the proper pressure.
6. A hand operated clipper comprising a handle having a post extending from one end thereof, a blade threadedly connected to the outer end of the post and extending transversely thereto, a sleeve rotatably fitted on the post, a driving member connected to the sleeve, a movable blade secured to the driving member and coacting with the fixed blade, a spring tension member having one end mounted on the post and one end cooperable with the movable blade and a nut threaded on the post to clamp the spring tension mem` ber and fixed blade in operative position.
7. A hand operated hair clipper comprising a handle having a post extending axially therefrom, a fixed blade secured adjacent the outer end of the post, extending transversely thereto and having teeth disposed in an arc struck from the axis of the post as a center, a movable blade mounted for oscillatory movement about the post as an axis and having teeth disposed in an arc struck from the post as a center and cooperable with the teeth of the fixed blade, the axes of the teeth of each blade being parallel and means for Inoving the movable blade back and forth in au are which has the post as a center.
In Witness whereof, we hereto affix our signatures.
