"Fig. 24 is a similar view to Fig. 23, but illustrating a modified construction.

Fig. 25 is a perspective view of the channel clipper body l0 having an oscillatory driver member H. In the drawings the clipper is illustrated as being electrically driven. However, this is merely for the purpose of illustration, and the device may be equally well applied to a manually operable clipper, or to a clipper having any other desired type of drive mechanism. On the drawings, the body In is characterized by a casing |2 enclosing an electric motor, not shown on the drawings, with the oscillatory member H extending from the front end thereof (as shown in 8). An" electric wire I 3 having a plug l4 for connection withan electric outlet socket extends .into the casing for supplying the required current tol operatethe motor. A switch I5 is mounted on the rear end of the casing I2 and is connected'in. the electric circuit, which includes the'motor; enclosed within the casing i2 and the source of energy for Controlling the operation ofthe motor.

A comb blade; is detachably mounted. upon the front end of the casing 12 of the clipper body Id. The detachable mounting of this comb blade I6 is characterized by a bracket N. This the cover 23.

bracket I! is of. amodified U-shaped configuration and hasv itsv intermediate arm securely attached to the top face of the. comb blade ,IS by screws l3. One arm of the modified U-shaped bracket extends upwards and slidablyengages an inclined track If! mountedupon the front end of the casing l2 of the clipper body ill. The track i9 ispart of a plate 20, see Fig. 25, secured in position upon the body H! by means of screws 2|. .This plate is also provided with oppositely disposed side walls 22 between which the rear is mounted upon a cover 23 secured, in position upon the front end of the casing |2 of the clipper body ill. The cover 23 is formed of sheet material and is provided with a pair of openings 24 through which screws 25 freely pass. The

screws 25 threadedly engage complementary openings 25 formed in the casing l2 for securing the cover 23 in position .upon the casing I2. The latchf2il' is. characterized by aplate 25 which engages over and covers an opening 2.6 formed in the cover 23 between the openings 24. An intermediate portion'Zl extends from the plate 25" and passes through the opening26. This intermediate portion 21 continues into a latch element 28 which is adapted to bear against the top 'end of the arm |1 of the modified U-shaped bracket I? for preventing disengagement of the arm from the track |9..

Means is provided for holding the plate 25' in a positionin which the latch element 28 will maintain its operative position with relation to the arm This means comprises a leaf sprin 29 having one of its ends securely attached to the rear edge of the latch element 23 and the other of its ends bent to engage the free top edge of the cover 23 and hold the plate 26 against being moved, see Fig. 5. A handle 30 is mounted on the leaf spring 29 and extends through an opening formed in the plate 25' permitting the spring 29 to be flexed to disengage its free end from the adjacent edge over the cover plate 23 permitting the plate 25 to be moved forwards, moving the latch element 28 to an inoperative position to free the bracket H.

A cutter blade 3| having teeth 32 formed on its front edge rests upon'the top face of the comb blade I6 and projects from the front edge of The rear edge of the comb blade 3| is provided with a cutout 33 into which the oscillatory drive member extends for causin the cutter blade 3| to be oscillated laterally relative to the comb blade IS.

A slide 34' is arranged for guiding the cutter blade 3| and for moving the cutter blade longitudinally relative to the comb blade |6 for controlling the length of the stub of hair remaining upon the head. This slide 34 is substantially U-shaped in plan view and has its arms straddling the bracket IT. The front edge of the slide 34 is raised upwards to extend along the top face of the cutter blade 3|. The front edge 35 of the slide 34 is bent to extend vertically downwards and engage a groove 36 formed in the top face of the cutter blade 3| for laterally slidably supporting the cutter blade 3| to be oscillable. The groove 36 is formed by providing the cutter blade 3| with spaced upwardly extended ribs 31 between which the front edge 35 of the slide 34 engages;

A member 38 is provided for supporting the slide 34 and for limiting its movement to the longitudinal. This slide supporting member 33 is preferably constructed of resilient spring material. and has its rear portion secured in position upon the top face of the intermediate arm of the bracket IT. This rear portion of the slide supporting member 38 is secured in position by the screws l8 which secure the bracket I! in position upon the comb blade I6. At its sides, the rear portion of the slide supporting member 38 is provided with downwardly extending lugs 39 which extend along opposite sides of the slid 34. The front portion of the slide supporting member 38 continues into upwardly projected finers 40 which rest on the sides of the intermediate arm of the slide 34 and which act to press the free front of the slide 34 downwards to maintain its front edge 35 in position within the groove 36.. The side edges of the fingers 4B are also provided with downwardly extending lugs 4| which engage the sides of the slide 34 for limiting its movement to the longitudinal.

Means is provided upon the casing I2 of the clipper body H! for moving the slide 34 longitudinally of the comb blade Hi to similarly move the cutter blade 3|. This means comprises a control handle 42 formed of separate sections 42 and 42 The section 42 is provided with a threaded stud 43 which engages a threaded opening in the adjacent end of the section 42 The handle 42 is slidably supported in a bracket 44 attached on the casing l2 by means of rivets 45. The bracket 44 has a hook portion 44 which engages about an intermediate portion of the handle 42. The handle 42 adjacent its rear end is provided with a pointed member 46 which is selectively set screw 48 from the groove 49, and this permits the handle to be disengaged from the hook portion 44*. The free end of the section 42 of the handle pivotally connects with a link 50 which extends downwards into the cover 23 and which freely engages into an opening formed in one of the arms of the slide 34. A rod 52 extends from the link 59 and is rotatively supported in a bearing 53 mounted on the plate 29.

This rod 52 has its free end 52 bent downwards and freely engaging into an opening 54 formed in the other arm of the slide 34. Thus" after the handle 42 is moved longitudinally of the casing l2 it will cause the rod 52 to pivot about the bearing 53 and move the slide 34 longitudinally of the comb blade Hi and similarly move the cutter blade 3|.

In Fig. 24 a V-shape portion 48 is formed integral with the handle 42 and is adapted to engage the longitudinal groove 49. In this form of the invention, the V-shape portion is substituted in place of the said screw 48.

In Fig. 1'7 a cutter blade 3| is shown which has shallower teeth 32' than the teeth of the cutter blade shown in Fig. 13. In other respects this'cutter blade 3| is similar in construction to the cutter blade shown in Fig. 13 and is adapted; to be interchanged with the previous cutter blade for controlling the length of the hair remaining on the persons head.

In Figs. 13 and 19 details of a slide for the blade shown in Fig. 1'7, is shown. This slide 34' is similar to the slide shown in Fig. 15, distinguishing in the fact that the front edge 35. if

is turned outwards. Ihe cutter blade 3| is provided with a relatively broad rib 31 which is adapted to slidably engage in the front portion of the slide 34', as schematically illustrated in Fig. 19. In other respects these parts are the same asthe corresponding prior parts, and like portions thereof may be recognized by identical reference numerals.

The operation of the device is as follows:

The plug I4 is engaged into a conventional 2' electric outlet socket and the switch I5 is moved to an on position to energize the motor contained within the casing H to drive the oscil latory drive member H to correspondingly oscillate the cutter blade 3| laterally relative to the comb blade I6.

If in using the clipper it is found that the device is leaving the hair on the head shorter than it is desired the position of the cutter blade 3| may be adjusted with relation to the comb blade Iii in the following manner. The handle 42 is pushed forwards causing the member 46 to ride over the serrations 4! and pivot the rod 52. This causes the ends of the link 53 and the end '52 of the rod to move rearwards and correspondingly move the slide 34. Since the front portion of the slide 34 connects with the cutter blade 3| it will pull the cutter blade rearwards in a longitudinal direction relative to the comb blade l6 and space the teeth 32 of the blade 3| rearwards ofthe teeth of'the comb blade I6.

It is also possible to remove the comb blade I6 and cutter blade 3| from the casing l2 together with its other attached parts, as shown in Fig. 26,

for permitting this unit to be conveniently sterilized and permitting the cutter blade 3| to be interchanged with other cutter blades. To accomplish this the handle 30 is moved forwards disengaging the end of the spring 29 from the free back edge of the cover 23 permitting the latch 2 0 to be moved forwards to disengage the latch member 28 from the upwardly extended arm of the bracket IT. This frees the bracket IT. The comb blade l6 and the parts carried by said comb blade may now be pivoted downwards until the rearportion ll of the bracket strikes the inclined track I9. This downward pivoting of the parts disengaged the bottom of the link 59 and the bottom end 52 of the rod 52 from the apertures 5| and 54 in the slide 34. The comb blade I6 and the parts carried by it may now be pulled forwards and completely disengaged from the remaining portion of the clipper.

In the modification of the invention shown in Figs. 2'7 and 28 a clipper is shown for use upon animals which is similar to that illustrated in the previous form of the invention except for a slightly different means for moving the cutter blade 3| longitudinally relative to the comb blade It. In this form of the invention the link 50' is fixedly attached to and extends upwards from the slide 34" and is provided at its top end with a knob 69 for moving it and the rod 52 and end 52 to move the slide 34". The casing l2 of the clipper body ID in this form of the invention is provided with serrations 6| adjacent an intermediate portion of the link 50' and acts to hold the link 59' against accidental movement. In other respects this form of the invention is similar to the previous form. i
