9 Claims;

This invention relates to hair clippers and more particularly to a motor-driven hair clipping assembly in which the cutting mechanism consists of a fixed cutting blade and a movable blade vibrating rapidly across the fixed blade.

The improved assembly comprises a clipper head housing, a motor, a cutting blade vibrating shaft, and cutting mechanism detachably secured to the clipper head. A feature of the invention is that the cutting mechanism may be readily detached from the clipper head for cleansing and sterilizing purposes. In clipping devices wherein the clipping mechanism and the casing contain ing the motor are integrally formed, it frequently happens that the motor is disabled during the cleansing operation. This possibility is eliminated in the improved assembly.

A further advantage of this device is that the movable cutting blade may be readily removed from the cutting mechanism. It is necessary for a well equipped barber shop tomaintain a stock of clippers having movable blades of various sizes. This improvement eliminates the necessity of having more than one clipper, since movable blades of various sizes may be readily inserted in the cutting mechanism.

A further feature is that the movable cutting blade may be easily removed for sharpening.

An object of the invention is to devise a clipper assembly in which the clipping mechanism can be readily detached from the clipper casing.

A further object of this invention is to devise an assembly in which the movable cutting blade may be readily removed from the cutting mechanism.

A further object of this invention is to devise an assembly for carrying out the above objects in a simple manner, said assembly to be cheap, easily detached, having but few parts and susceptible to convenient and precise manipulation.

My invention will be readily understood from the following description in conjunction with the accompanying drawing, wherein a preferred embodiment of my invention is shown, in which:

Figure 1 is a perspective view of the improved hair clipper assembly;

Fig. 2 is a rear perspective view of the assembly with the clipping mechanism removed;

Fig. 3 is a rear elevation of the cutting mechanism;

Fig. 4 is a fragmentary horizontal sectional view along lines 4-4 of Figure 1;

Fig. 5 is a fragmentary vertical sectional view along lines 5-5 of Fig. 4; and

,face 6a of the casing.

Fig. 6 is a fragmentary sectional view along lines 66' of Fig. 4.

Referring to the drawing, the numeral 6 indicates a clipper casing of substantially conventional outline having a face 5a provided with 5 bores 6b adapted to support clipping mechanism hereinafter described. The casing 5 houses a motor (not shown) adapted to rapidly vibrate a bar 1, centrally disposed within said casing and protruding forwardly therefrom. A pair of plates 8 and 9 are disposed one above the other across a portion of the front face of the clipper head ii. The uppermost plate ii is provided with a pair of spaced apertures ill and is fixedly secured to the head 6, in any suitable manner, for example by screws H. The underlying plate 9 has a right angled portion 92 extending laterally along one side of the casing 6. A spring l3 disposed within the-side of the casing and extending outwardly therefrom bears against the flange-portion I2, yieldingly urging said flange-portion away from the side wall of the casing. The plate 5 is provided with slots 9a longitudinal thereto housing rivets 9b slidably uniting plates 8 and 9 and permitting limited movement of plate 5! across the 5 Portions of the plate 9 are cut away forming rounded apertures i4 and shoulders Ma. The openings ii are spaced to be in alignment with the apertures H of plate 8 when flange i2 is pressed inwardly and plate 9 3 is in its innermost position.

Detachably secured to the face of the head 5 is a cutting lip 15 comprising a body portion 16 terminating in a cutting blade il having a number of sharpened cutting teeth is. Fixedly secured to the upper side of the body portion 16 is a strong steel clip l9 having a ridged portion 19a adapted to engage a groove 26 extending 1ongitudinally along the entire length of a movable cutting blade 2| and to retain the movable blade in operative relationship to the blade ii. The movable clipper blade 2! is shorter in length than the fixed blade 11 and. is provided with a cut-out portion 22 along the rear thereof and having a greater cross section than the bar 5. A central portion 19a of the clip i9 is likewise cut away to permit the bar to pass therethrough.

It is readily apparent that when the cutting mechanism is secured to the head, the bar l fits into the cut-out portion 22 of the movable clipper blade and is adapted to rapidly move the blade 21 back and forth across the fixed blade ll upon vibration of the bar I. The movable blade 2| may be easily removed from the clip by detaching the clipping mechanism from its head, as

outwardly, and the shoulders Ma adjoining apertures l4 engage the annular grooves 24 of the lugs, firmly retaining the cutting mechanism IS in an operative position. Thus it will be seen that the cutting mechanism may readily be removed from the head by pressing the flange l2 inwardly thereby disengaging the shoulders Ha from the grooves 24. 7

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is:

1. A clipper assembly comprising a clipper head, clipper driving mechanism carried in said head, a cutting lip including a clipper blade forming a part thereof and a movable blade cooperating with the first mentioned blade, and means for detachably securing said head and lip comprising grooved members depending from said lip, an apertured member on said head to receive said lugs and a manually operable spring pressed member slidably mounted on said head yieldingly engaging said grooved members.
