Application filed August as, isas. serial No. 659,286.

To all whom it may concern:

Be it known that l, HARRY ,0, SMITH, a citizen ofthe United States, residing at Los Angeles, in the county of Los' Angeles 5 and State of California, have invented certain new and useful Improvements in a Clipper; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en- W able others skilled in the art to which appertains to make and use the same.

This invention relates to a clipper primarily designed for use by barbers.

The object of the present invention is to 1% improve the clipper structure disclosed in my copending application filed May 1,1923

; and serlally numbered 635,917.

Another object of the present invention is to provide a, clipper of the type disclosed in my application above referred to, in

which there is included a novel form of stationary cutter blade,

A still further object of the invention is to rovidea small and compact clipper emb0 ying a substantially direct operating 1 means for shifting a slidin block carrying thetop or movable cutter b ade'to move the same longitudinallyof the clipper to pro; vide for the tapering of the edges ofv the ile the following description and faccompanying drawings disclosed the preferred embodiment of my invention, it is to be understood that changes in the details of construction and arrangement of parts may be resorted to provided they fall within the scope of what is claimed.

'Referring to the accompanying drawings illustrating an operative embodiment of the to invention:

Figure 1 is a side elevational view of the clipper constructed in accordance with my invention, parts being broken away to illustrate the means for adjusting the movable V 4 cutter blade,

Figure 2 is a top plan view of the-same, Figure 3 is a bottom plan view of the clipper, the handle" being omitted, v

igure dis a sectional view on the line Figure 5 is a sectional view on the line 5--5 of Figure 1, Figure 6 is a sectional view taken on the plane indicateddoy the line 6--6 of Fig- 5e ure 5,

Figure 7' is a detail perspective view of v the stationary cutter blade,

i Figure 8 is a detailed movable cutter blade.

Referring specifically'to the drawings a head or block is provided at 10 from which a handle 11 extends rearwardly. The head lO at the under or head-engaging surface 1s inclined as at 12. Detachably secured to the head by means of screws or fastening means 13 is a stationary cutter blade 15 having a plurality of slits or incisions to provide the hair separating fingers 14:. This general structure is disclosed in my copending application above referred to, but the stationary cutter blade 15 of the present perspective of the application embodies features not contained in the stationary cutter blade pending application.

Wing extensions 16 are formed integral with the stationary cutter blade 15, and the wings are spaced apart-and a wing is arranged above each of the teethof the stationary cutter blade. The upper surfaces of the wings are made oval so as not to become entangled in the hair as theclipper is moved therethrough. The space 17 between the upper surface of? the cutter blade 15 and the winged extensions 16 is of such dimensions as to receive a reciprocating cutter blade 18 and to. allow free movement thereof and'also to provide enough space to of my ooprevent hair from clogging between the 'are all formed integral with a cross bar or rib 19, and as clearly shown in Figure 7 the ends of the rib or bar 19 are connected with the body of the stationary cutter blade by side walls 19 The movable cutter blade 18 has its forward or active end reduced to provide a shoulder at 20 which whenthe movable cutter blade is in its extreme 'forward position, willcontact with the rib or'bar 19 and prevent the teethof the movable eutter'blade from catching in the forward end of the stationary cutter blade at the point where the winged extensions connect with the forward end of the stationary cutter'blade.

Slidable within the head 10 and longitudinally thereof is the positioning block 21 carrying the movable cutter blade 18. The block 21 is overlapped by the arms 22 forming the attaching portions of the stationary or bottom blade 15 of the clipper. The movstructure which is disclosed in my copendingapplication, and which includes an electrie motor 24' located within the handle 11, and to which feed wires 25 are connected and which lead from any suitable source.

In order that the clippers may be adjusted or set'to cut hair at different lengths,

the block 21' slides on a pin 26 which at its rear end abuts the end wall 27 of the head 10. Thepin 26 is surrounded by an expansive -coil spring! 28 that engages the head 29 of the pin and also engages the block 21. The spring 28 will therefore urge will be. moved forwardl the block 21 forwardly and the cutter 18 l as it is carried by the sliding block throug the medium of the bosses 24.

As in my former structure, a bracket 30 extends over the cutter 18 and the bosses 24 and may be fastened .to the latter by m'eansof set screws 31. The bracket .30 has ears 32 integral therewith to which pawls 33 are pivoted by horizontal pins 34. Said pawls at their free ends are adapted to engage teeth 35 providedon the head 10, in

order to hold the cutter 18 and block 21 i in its adjusted position against the tension of the spring 28. The bracket 30 may have a cover 36 removably. fastened thereto by bolts or the like at 37. A vertical bolt. 38 rises from the bracket 30 to the cover 36 and has a follower 39 loosely slidable alon the same. Levers 40 are pivoted to the ollower 39 and the pawls 33 and have enlarged eyes 41 through which the bolts pass and on which bolts said levers fulcrum. A depress'ible sleeve or operating member 42 is slidable along the bolt 38 having its .lower end in engagement with .the follower'39 and itsupper end disposed exteriorly of the bracket and engaged by 'a nut 43 threaded on the bolt 38. An ex pansive coil spring 44 surrounds the bolt 38 and at one end engages bracket. 30 and at its other end engages the lower surface of the follower :39. With the parts propel.

. 1y adjusted the spring 44 by its urging the follower 39 upwardly "to the extent permits ted by the operating member 42 and nut 43,

maintains the pawls 33 in engagement with the proper teeth 35. When quickdetach- .cut so as to rotate the rollers.

ment of said teeth is desired the sleeve 42 is depressed in order to slide the follower 39 against the tension of the spring 44 thereby tilting the levers 40 and raising and disengaging the pawls 33 from the teeth 35.

Side plates 45 are attached to the head 10 by means of screws or like fastenings 46 and extend slightly above the upper surface of the head 10 and with the extensions or attaching portions 22 of the stationary cutter blade 15 provide walls at each side of th' 'teeth 35. Thus it will be seen that the pawls slide between walls formed by the extensions 22 and the plates 45.

To the end that the operator may control the depth of cut at the edges of the hair, the head 10 is provided with a pair of spaced parallel slots 47 through which gear wheels 48 operate. Pivoted to the plates 45 as at 49 are arms 50. Carried by these arms at their lower ends is a shaft 51 which is disposed in a recess 52 in the inclined wall of the head 10. J ournaled on the shaft 51 area plurality of rollers 53 which preferably have peripheries of rubber in order that they may have tractive effect on the head of the person whose hair is being Rotatable with each of the rollers 53 is a gear wheel or pinion 54. The pinion 54 drives the pinions-48 which are journaled on a shaft 55 which is secured to the head 10 by means of fastenings 56. The upper pinions or gears 48 mesh with racks 57 which are rovided in grooves 58 on the under sur ace er the sliding block 21. With the upper pinions 48 in engagement with the teeth 57 and the rollers 53 engagin the head of the person, the .rollerswill he rotated as theclipper is'pushed over the head so as tothereby control the position of the cutter plate.18. As will be understood forward pushing movement of the clipper will cause retraction of the cutter 18 against the tension of the spring 28 and the cut ter may be restored to normal position or toward normal position by expansion of the spring 28 when the rollers are rotating in the reverse direction.

When this feature of the invention is not desired, the rollers 53 may be moved to inoperative position, by swinging them within the opening or recess 52 in the head 10, and they may be secure in operative I position by tightening the nut 58 so as to clamp the shaft 51 toan arcuate strip 59 which is secured within the recess 52. The

rollers may all be secured in their operative positions by moving them into their operative positions and clamping them in that position by turning the'nut 58.

A presser frame 60 is pivoted to a lug 61 on the handle 11, and this frame directly engages. the upper surface of the cutter 18 with which it coacts. 'Ihe presser frame is designed to assist in holding the upper cutter blade against vertical movement.

Having thus claimed the invention, what I claim is I. In a clipper, a head, a stationary cutter blade carried by said head, a block slidable in said head and having upstanding bosses, a cutter plate having recesses enlarged with respect to said bosses and receiving them, said cutter plate coacting with-said station- I ary cutter blade, said head having a recess,

a roller journaled to rotate in said recess, a gear rotatable with said roller, teeth formed on the under side of said block, and a gear meshing with said first named gear and said teeth and adapted to move said block when said roller isrotated.

2. In a clipper, ahead, a stationary cutter blade carried by said head, a block slidable in said head-and having upstanding bosses,

said block having a groove in its under surface, teeth formed on said block at the bottom of said groove, a cutter plate having recesses enlarged with respect to said bosses and receiving them, said cutter plate coacting with the stationary cutter blade and movable with said block, said headv underside of said block and-at the bottom of said groove, and a gear meshing with said first named gear and extending through said slot in the head and into the groove in the block, and said second named meshing with the teeth andadapted to move the block when the roller is rotated.

In testimony whereof I afiix my signature in presence of two witnesses.-

. HARRY O. S'III.
