" JOHN CAMPBELL, OE MINNEAPOLIS MINNESOTA, AssIeNon or ONE-HALE ro AUGUSTUS s. DOWDALL, OE MINNEAPOLIs, MINNESOTA.
]?OWERDRIVEN HAIR CLIPPER.
Application filed July 6, 1920. Serial No. 394,107.
To allwtom tm/ty concern: y
Be `it known that LJoI-IN CAMPBELL, a citizen .of theUnited States, residing at Minneapolis, in the county of Hennepin and State of `liflinnesota, have invented certain new and useful Improvements in Power- Driven HairClippeI-s; and I do hereby declarethe following to be a full, clear, `and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same.
`l\ly`invention has for its object to providean extremely simple and highly eiii cient power `drvenhair clipper, and to such ends, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims. i i v rlhe invention `also involves a comb combined with cooperating toothed clipper blades in such a manner that itmay beeffectually utilized in the hair clipping ac tion. The power for driving the movable clipper blade is `preferably `transmitted through a flexible shaft, and the mechanism for transmitting the :rotary motion of the shaft into reciprocating `movement of the movable clipper blade is located vwit-hin the hollow handle of the clipper.
In lthe accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.
Referring to the drawings:
Fig. 1 is a plan view of the clipper with oneside of the handle removed;
Fig. 2 is a section on the lino 2N2 of Fig. 1;
Fig. 3 is a perspective view showing the comb removed;
Fig. 4; is a perspective view showing the sheath and combl holder in detail;
Fig. 5 is a perspective view showing the removable clipper blade removed;
Fig. 6 is a side view of the retaining bar used in the device;
Fig. 7 is a perspective view showing a relatively fixed clipper blade and handle section to which it is secured;
Fig. 8 is a perspective view of one of the clamping screws; and
Fig. S) is a. section on the line 9 Fig. 1.
The handle of the device is a hollow structure made up of two sections 10 and 11 rigidly secured together by screws or rivets 12.
Y) of The handle Vsection l() is either formed integral with or otherwise rigidly secured to a relatively fixed clipper blade 13, which, at one edge, has sharp edgedlong teeth 111 that afford a sort of comb-like structure. lVorking against the face of the clipper blade 13 is a quite similar, but relatively movable bladeil provided with cutting teeth 16 that co-operate with the teeth 14 to cut the `hair when the movable blade is reciprocated. The blade 13 is provided with projecting bosses 17 ,that project through longitudinal slots 1S, in the movablegblade 15, and guide the same for straightdine movement longitudinally thereof.
` The numeii'al 19indicates a retaining bar provided with perforations 20 that are adapted to align with holes 17L in the bosses 17. These holes 17L are internally threaded to receive clamping screws 2l. By means of the screws 21, thebar 19 can be directly secured to the bosses`17 so as to thereby operatively connect the two clipper blades without the use of any other devices. y
The movable clipper blade 15 has an eX- tended bar 22 that slides through keepers 23 on the handle sections 10. The numeral 24 indicates afiexible power shaft, which may be driven from any source of power, such as a stationary electric motor. This shaft 2li, at its extended end, is connected to a driving shaft 25 journaled in bearings 26 on the in-` terior of the handle section 10. This shaft 25 carries a worm 27, that meshes with a worm gear 28 journaled on a stud 29 located on the interior of the handle section 10. The worm gear 28 has a wrist pin or crank 30, that is connected by a pitman 31 to the bar 22 of the movable clipper blade 15.
For the attachment of the comb 32, shown in detail in Fig. 3, I provide the combined sheath and comb holder 83, shown in detail in Fig. 4L. The comb 32, at its back edge, has an enlarged rounded bead 34;, and to 'receive this bead, the sheath 33, at one edge is provided with a slot 35 that opens into a longitudinal hole 36. The hole 3G is of such size as to frictionally clamp the bead 34 of the comb 32 when the latter is slid endwise 4wide enough to embrace and closely fit the outer faces of the two clipper blades 13 and 1 15 when the two are assembled, but with the retaining bar 19 removed. When the sheath is thus applied, the clamping screw 421 may be passed through holes 38 in one sideof said sheath and screwed into the bosses 17, thereby anchoring the sheath to the relatively fixed blade 13, but leaving the blade 15 free for reciprocation. `When'the sheath isv a plied, asj-ust described, the bar 19 may, if desired, be clamped against one side of the sheath, as shown in Fig. 1, by mea-ns of the screws 21.` Y
The above `described varrangement of the clipper blades'at vone side or edge and of the comb ,at the other, is highly important.` In cutting hair very short, the v'clipper blades will, ofcourse, be run closeto the scalp, but in Cutting or trimming hair ot' any considerable length, the device will be moved in one direction so asto collect thehair in the comb, then the hair will be gripped'iu the usual wav, between the fingers of the lefthand, and the outer portion thereof `will be trimmed off by a backward swinging movement of the device such `as required to force the clipper blades against the hair. Thus, it will be seen that the combined combing and cuttin" action' can be produced very rapidlyan properly by .a to and fro lateral swingmgmovement of the clipper. Rapid hair cutting isr thus made possible. 1 What .I claim is: y y
1. A power driven hair clipper comprising a'handle, co-operative relatively fixed andV movable clipper blades applied to said handle and having teeth at one side ed e thereof, a sheath detachably ap lied to tie fixed blade and embracing both lades, said sheath, at the side edge opposite the teeth of said clipper blades, having a comb-ho1ding channel, and a comb detachably held in said channel wit-h its teeth projectin in a direction away from the teeth of sai cli per blades and in substantially the same p ane as said blades.
2. A substantially flat hair cutting implement having in combination a handle portion, a toothed comb secured thereto and extending longitudinally thereo, and a reciprocating cutting mechanism secured to said handle and extending longitudinally thereof, comprising a stationary toothed member and a movable toothed member the tee-th of said members being disposed oppositelyto the teeth of said comb.
3. A substantially flat hair cutting implement having in combination a handle member comprising a fixed toothed portion, a movable toothed cutting member adapted to reciprocate in close proximit to said toothed portion, the teeth of sai members extending at one side of said device, and a comb at the other side of said device having its teeth projecting in the opposite direction to the teeth of said members and in substantially the same plane.
4. The structure set forth in claim 4, and means in said handle for reciprocating said movable cutting member.
5. The structure set forth in claim 4, and a. sheath member secured to said handle and enclosing said toothed portion and toothed cutting member and in which said comb is removably mounted.
In testimony whereof I aix mv signature.
l JOHN CAMPBELL.
