HARRY o.` smrmor Los ANGELES, CALIFORNIA.

GLIPPER.

Application led May 1,

To all whom it may concern.'

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

This invention relates to a clipper primarily adapted for barbers use.

One object is to provide a clipper operable upwardly to cut hair at the lower edge lto give an upward and outward taper and particularly a clipper which may fulcrum on the headv tov attain this result or otherwise cut hair at different lengths.

It is further aimed to provide a construction in which the hair may be cut to a uniform length and which may be adjusted to vary or control the different lengths of cut.

Another object is to provide a construction having tractive means to engage the head and a cutter whose position varies automaticallv with that of said means to control the taper cut referred to.

A fourth object is to provide a construction in which said tractive means is movable into and out of utile position to the end that the clipper may normally function as an ordinary clipper.

A further object is to provide a clipper having novel means to lock the top plate or movable cutter blade in different adjusted ositions so as to cut hair to diEerent engths.

A still further object is to provide a clipper in which the motor is located in the handle in order to e-liminate the stiff drive cable or the equivalent normally extending from the handle.

A novel tensioning means for the cutter o1 top plate is also a feature of the invention.

Various additional objects and advantages will become apparent `and be pointed out from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

Y Like reference characters designate like or similar parts in the different views.

Referring, specifically to the drawings, av

block or head is provided at 10 from whicli' a handle 11 projects rearwardly. The head 10 at the hair engaging portion longitudinally of the clipper is preferably, triangular as shown so that its under or head-engaging surface will be inclined as at 12. Detachably secured to the head l0 by screws or other fastening means 13 is the stationary cutter blade 15 having a plurality of slits or incisions to provide the hair-separating fingers 14:.

Slidable within the head 1() and longitudinally thereof is a cutter plate positioning block 16. The ends of block 16 are overlapped by the arms 17 forming the attaching portiontof. the stationary blade 15. 'Ihe upper surface of the head 10 with the stationary cutter blade 15 in place is preferably substantially Iplane/,and a cutter blade 18 is slidable on said plane surface both longitudinally and laterally of the clipper in both directions. vThe head 10 at each side is raised above said plane1 surface at portions 19.

vso

Cutter 18 has slots 2() therethrough into I Itact with the 'commutator 29.

wires 27 are permanently secured to the ally reciproca-ted in any approved manner. To this end an electric motor 22 is located within the handle and feed wires 23 lead thereto from any suitable source. The motor 22 comprises the armature 24 and field 25 which latter is insulated from the casing or handle 11 by suitable electric insulating material 26 through which feed wires 27 extend to the brushes 28 insulated from the handle as shown and having con- The feed Sockets 30 embedded in the block of insulating material 31 and the feed wires 23 are permanently secured to studs 32 embedded in the block of insulating material 33. rlhe studs 32 and sockets 30 provide a quick detachable electric connection and obviate the necessity for the employment of feed wires 23 of great length.

Particular attention is called to the fact that by having the motor located within the handle 11, the use of an ordinary flexible shaft or other relatively stiffl means at the free end of the handle is avoided. The feed wires 23 may be ordinary exible electric wire or cord. The motor is adapted to rotate a drive wheel 34 from an axis longitudinally of the handle.

A fan wheel 35 is associated to turn with the drive wheel 34 so that air will be educed from the handle toward the head and serve to dislodge hair after the cutting thereof. A bolt or rod 36 is disposed radially of the handle 11 at its forward end in an upright position. A block 37 is journaled on the bolt 36 and a horizontal pin 38 connects a drive -rod 39 thereto. The drive rod 39 has a ball and socket or swivel connection at 40 with the vwheel 34. As a result, the drive wheel 34 will so move the rod 39 as to oscillate the block 37. A crank 41 extends forwardly from the block 37 and has an upstanding lug 42 as at forward end which is disposed within an elongated slot 43 of the cutter 18.`

The cutter plate 18 may be of any suitable shape but preferably has spaced forwardly projecting fingers or teeth 44 suitably sharpened at their side edges so that as the cutterV plate reciprocates laterally over the fingers 14, such plate will cut the hair ex tendingabove the fingers 14.

One of the principal features of my invention is to provide means whereby the same may be set to cut the hair at different lengths. To this end, the block 16 slides on a pin 45 which atits rear end abuts a plate'46. At said end, 'pin 45 has ahead 47 which is surrounded by an expansive coil spring 48 which engages head 47 at one end and the block 16 at the other end. rllhus i the spring 48 kurges the" block 16 forwardly and also the cutter 18 "forwardly as it is connected to the block through the medium of the bosses 21.

'Suitable means is provided to maintain' the block 16 and cutter 18 at different positions away from the free end of the fingers 14 and against the tension of the spring 48 so that the fingers 14 may extend into the hair to different degrees to regulate the length of cut thereof. Y

A bracket 49 extends over the cutter 18 and bosses 21 and may be fastened to the latter by means of set screws 50. Bracket 49 has ears 51 integral therewith to which pawls 52 are pivoted by horizontal pins 5 3. Said pawls at their free ends are adapted to engage teeth 54 provided on the head 10 in order to hold the cutter 18 and block 16- against the tension of the spring 48. in the adjusted positions of the cutter. Bracket 49 may have a cover 55 removably fastened thereto by bolts or the like at 56. A vertical bolt 57 rises from the bracket 49 and through the cover 55 and has a follower 58 loosely slidable along the same. Levers 59 are pivoted to the follower 58 and to the pawls 52 and have enlarged eyes 60 through which the bolts 56 pass and on which bolts said levers fulcrum. 'A depressible sleeve or operating member 61 is slidable along bolt 57 having its lower end in engagement with the follower 58 and its upper end disposed -exteriorly of the bracket and engaged by a nut 62 threaded on the bolt 57. An expansive coil spring 63 surrounds bolt 57 and at one end engages bracket 49 and at its up.- per end engages the lower surface of the follower 58. With the parts properly adjusted, the spring 63 by its urging the follower 58 upwardly to the extent permitted by the operating member 61 and nut 62, maintains the pawls 52 in engagement with the proper teeth 54. Then quick detachment of said teeth is desired, the sleeve 61 is depressed in order to slide the follower 58 against the tension of spring 63, accordingly tilting levers 59 and raising and disengaging pawls 52 from the teeth 54. l/Vhen itl is desired that such disengagement of the p-awls from the teeth should be permanent, the nut 62 is screwed downwardly against the operating member 61 to such an extent that it cannot move upwardly sufficient to enable the pawls to fall into engagement with teeth 54. The presence of this mechanism to lock the cutter plate 18 in adjusted position 'does not interfere with the use of the cutter plate in its normal position similar' to au ordinary clipper.

A very important feature of the present invention is the provision of means whereby the operator may control the depth of' cut at the edges ofthe hair and particularly may give the line of cut an upward and Adisposed in a recess 70 in the inclined surface 12 of the head 10. Journaled on the shaft 69 are a plurality of rollers 71 which preferably have peripheries of rubber at 72 in order that they may have tractive effect on the head of the person whose hair is being cut so as to rotate the rollers 71. Turnable with the rollers 71 is a gear wheel or inion 73. Pinion 73 drives a pinion 74 which is journaled on a pin 75 extending from the arms 68. The upper pinion 74 meshes with rack or gear teeth 76 provided on downwardly extending wings 77 integral with the bracket 49 and disposed in the recesses 70. With the upper pinion 74 in engagement with the teeth 76 and the rollers 71 engaging the head of the person, such rollers will .be rotated as the clipper is pushed over the head so as to thereby control the position of the cutter plate 18. As will be understood, forward pushing move- `ment of the clipper will cause retractionof the cutter 18 against the tension o f the spring 48 and that the cutter may be restored to normal position or towardnormal position by the expansion of spring 48 when the rollers are rot-ated in the reverse Way.

It will be realized that when the feature last referred to is not desired, as in the ordinary clippingvof the hair, the upper pinion 74 may be disengaged from the rack teeth 76 by swinging the arms 68 on their pivots so that the upper pinion 74 will move rearwardly and de-mesh with respect to the gear teeth 76.

A guide and securing strip for shaft 69 is provided at 77. The forward end of said strip is returned and fits against a wall of the recess 70. The strip 77 also has an arcuate portion 78 provided with an elongated slot 79 through which a bolt 80 passes and which extends rigidly from the shaft 69. A nut 81 is threaded on said vbolt 80. lt will be realized'therefore that with. the nut 81 loosened, that the same. and bolt 80 serve as .a manipulating handle to swing the plates and associated parts so that the pinion 74 will engage and disengage the teeth 76. The nut 81 may be tightened to bind against the strip 77 and thus maintain such parts either in a utile orvin an inutile position. Attention is called to the fact that 1n the inutile position of the rollers 71 that they are completely disposed within4 the recess so as not to offer obstruction to passage of the clipper over the head in normal use thereof.

A presser frame 82 is pivoted to a lug 83 on the handle 11. This frame may be made of a bar or rod of metal and at its forward portion directly engage the upper surface of the cutter 18 with which it coacts. The bolt 36 extends through'the frame and an expansive coil spring 84 surrounds said bolt 36 and rests on the frame. A nut 85 is threaded on bolt 36 and engages said spring 84 so as to vary its tension and accordingly vary the tension at which the frame 82 engages the cutter 18. As the frame 82 is pivoted, the same may be readily swung.

from across the operating parts when the nut 85 and spring 84 are removed, and it is necessary or desirable to inspect the operating parts.

A modified form is shown in Figure 9 relating principally to the drive for rotatable wheel 34. -Said wheel is keyed to a drive shaft 86 journaled in bearings 87 disposed within handle 11. A fly wheel 88 maybe carried by shaft 86. A flexible drive shaft 89 isemployed preferably driven by an electric motor at a distance from the clipper. A socket90 on handle 11 detachably receives one end of shaft 89 and the latter is coupled to shaft 86 by an attaching lug 91 on shaft 89 removably entering a slot 92 inthe shaft 86. Accidental detachment of shaft 89 from socket 90 is prevented'by a ball 93 entering a groove 94 in shaft 89. Ball 93 is contained in a tube 95 on handle 11 and cannot become downwardly displaced as the lower end of said tube is constricted at 96. An expansive spring 97 in the tube coacts with ball 93. A nut 88 engages spring 97 and closes tube 95. The clipper in advance of wheel 34 in this modified form is the same as the construction first described.

lfn the modified form of my invention shown in Figure 11 a solid head 98 generally triangular in outline is connected to a handle 99 through the medium of a bolt 100 on which is mounted for oscillating movement a block 101 connected to a drive rod 102 which in turn is connected by a swivel joint 103 to a drive wheel 34. The swivel joint 103 comprises the horizontal. pivot 104 and the vertical pivot 105 and is of the same construction as the joint shown in the form of my invention illustrated in Figure 9. Secured to the forward inclined face of the head 98 by fasteners 106 is a stationary cutter blade or plate 107, the same being of standard construction and having upstanding lugs 108 extending through horizontal slots 109 in the movable ,cutter plate 110. rlhe connection between the block 101 and the movable cutter plate or blade 110 is made by the rod 111 which is shown as being integral With the oscillating block 101 and which enters a notch 112 in the movable blade. rllhe bolt 100 passes through a presser member 113 pivoted at 114 and which bears on the movable cutter blade to hold the same against the stationary cutter member. A nut 115 is mounted on the outer end of the bolt 10Q and a coil spring 116 is interposed between the nut and presser member 113 for a purpose already described.
