Fig. 8 is a fragmentary side elevational view illustrating an indicator used in the invention.

As shown in the drawing, the invention comprises a casing or housing having the bottom I5, the side walls I6 and Il and the rear Wall 151 82. Positioned within this casing is a rigid frame comprising the oppositely disposed vertically extended side rails I8 and I9, the top rail 23 and the bottom rail 2I. A bearing boss 22 is mounted on the inner face of the bottom I5 and a bear- 20 ing boss 23 is formed on the inner face of the top rail 20. In hair clippers, as commonly constructed, there are generally two cutter plates which are movablerelatively to each other. I have illustrated the invention used with a clip- 25 per having the stationary cutter plate 24, on the outer edge of which are formed the cutter teeth 33. This cutter plate 24 is secured to the bottom wall I5 of the casing and in engagement with the outer surface thereof by screws 25 30 which also serve to secure a supporting plate or block 25 in engagement with the bottom I5 over the cutter plate 24. A recess 21 is formed in the upper face of the plate or block 25, and a pivot stud 28 projects upwardly through the recess 35 2'I to form a pivot pin for the actuating arm 29, which is pivoted thereon. AA cover plate 30 is held in position to retain the actuating arm 29 on the pivot pin 28 by means of the spring washer 3I' and the nut 32 which is threaded on the 40 reduced threaded end of the pin 28. This cover plate 30 is turned downwardly at its forward edge to engage a cutter blade 35 and press the same firmly against the cutter plate 24, with the proper degree of tension. This movable cut- 45 ter blade 35 is slidably positioned on the upper surface of the stationary cutter plate 24, this movablecutter blade 35 having at one edge the cutting teeth 34. Slots 36 are formed in the cutter blade 35 and extending into these slots 50 are extensions 31 carriedV by and projecting upwardly from the stationary cutter plate 24. Formed in the rear edge of the cutter blade 35 is a notch 38 in which engages a head 39 formed on the actuating arm 29.

The rear end of the arm 29 terminates in the upwardly angularly turned rearwardly directed forked members 40 so as to provide the space 4I in which engages a crank 42. This crank 42 is formed intermediate the ends of a shaft, one end 43 of which is journaled in the bearing boss 22 and the other end 44 of which is journaled in the bearing boss 23. Fixedly mounted on this shaft intermediate its ends is a gear 45 which meshes with a worm 46 formed on the shaft 41 which is journaled in the bearing block 48 mounted inthe rear wall 82 of the casing. It is intended that the shaft 41 shall be driven by an electric motor through a suitable exible shafting connection. The inner end 49 of the shaft 41 is journaled in the v bearing 50 carried on the lower end ofthe bracket 5| which extends outwardly and downwardly from the upper rail 20 of the frame. The worm 46 also meshes with a gear 52 which is `i-lxedly mounted on the shaft 53. This shaft 53 projects through the enlarged portion .55of the frame rail I9 and is providedwith.thespacing collar 54'. The shaft 53.projects through. a housing 56 mounted on the outer surface of the casing wall I6. The outer end vofsthe'shaftf53 is journaled in a bracket 51 which is. also mounted on the wall I6. Projectinginto this housing 56 are the shafts 58 and 59, each of #which lextends transversely of the casing and projects through supporting plates 60 and 60', mountedwon the walls I1 and I6. Fixedly mounted on the shaft 53 .within the housing 56 is apulley 6|. A pulley 62 is fixedly mounted ontheshaft 58 .within the housing 56 anda pulley :63 is-xedly mounted on the shaft 59 within-the housing 56. A'belt, formed preferably from vanwendless'spring 64, passes around over all these pulleys lso `that when the shaft 41 is rotated to eiect a'rotation of the shaft 53, all of the pulleys rwill be-'rotated and since these pulleysA are fxedly mounted on their respective shafts, the'shafts A58rand 59 will also be rotated. It is obvious `thatfwhilethe shaft 41 is beingrotated,.,theactuatingI arm29 will be oscillated to effect areciprocationof the movable cutter blade.35.=

Fixedly mountedon the shaft 59 between plates 60 and 60 are discs 65 radiating outwardly from which are the arms 66.- A presser-*plate 61 having an outer angularly turned edge 68 .is xedly mounted on a rod 10 fwhich extends throughan oppositely positioned aligning pairofvarms 66.

The shaft 59 is providedwith anelong'ated co1.

lar 1I 4at vthat portion which lies between the discs 65,'and mounted centrally Eon'this collar is a ring 12 of yieldable material suchl as rubber and the like, and against -which av rearwardly projecting tongue 13 formed on the rear vedge of each of the plates 61 is adapted to normallyengage. A spiral 'spring.69 coiled about the shaft 10 and engaging, at one of its ends, the -discs 65 is adapted to normally retaintheplates 61 locked to that position inwhich the :tongue 13 will engage Athe ring 12.' A cam bar 14is provided with an angularly turned .flange 16zwhich is attached to the side wall I6 of 'thelcasing The camfbar overlies the forward'end ofthe guard plate 11 which is positioned between and engages, at yits opposite edge, the'side walls vI6 and I1 and which is provided on its inner surface with a layer 11 of felt or the like.A The upper end of this guard plate is angularlyturned as at .18 to lie substantiallyv parallel '.tothe bottom: I5.` The rear end of this angularlygturned portion is suit` ably secured to the upper endof the backof the casing. As clearly'shown in Fig.; 2,;,the guard plate 30 projects forwardly of and serves as a cover for the recess 38 and the slots 36, so that access of hair to these parts, which might result in clogging of the mechanism, is prevented. The guard plate 11 projects forwardly of and overlies a cover plate 19 having at its opposite edges the downwardly projected ange 80. The under surface of this plate 19 is provided with a layer 8| of felt or the like so as to afford a protective covering for the pivot pin and the actuating parts.. Fixedly mounted upon the shaft 58 between the plates 60 and 60 is a cylindrical brush 83 which, when rotated, is adapted to engage the comb or tooth plate 84 which is secured to the-forward edge of a cover which comprises the top 81 and the sides 88. A plate 89 is mounted between plates 60 and 60 to reinforce the construction and form a cover for the brush 83.

Mounted on the under surface of the bottom I 5 of the casing, adjacent the forward end thereof, isan inverted'U-shaped support 90, projecting outwardly from the forward side of which are the guide rods 9| which extend through the partitions 92 'and 93 carried by a comb-forming regulating shoe comprising the bottom'96 and the oppositely disposed side walls 95 and the rear wall 94. The forward edge is provided with teeth 91. A spring 98 is connected at one end to the partition.93 and at its opposite end to the bottom I5 sol asto normally resist slidablemovement of this regulating guide shoe or comb forwardly from the position shown in Fig. 2. In Fig. 3 'I have shown this guide shoe or comb-forming member pressed forwardly to its forwardmost position.

Mounted on the side wall I1 is a bearing 99 throughywhich extends the rockably mounted stud .or shaft |0I, to the upper end of which is fx-edly. mounted the head |03, projecting outwardly from which is the finger grip I 02. Fixedly mounted,v at one'end, on the lower end of the shaft |0| is a plate |04, the free end. of which is angularly turned downwardly to provide the engaging portion |05 which normally lies in engagement with the outer surface of the rear wall 94 'of' the regulating guide shoe. A boss |06 is formed on the member 90 and threaded through this boss is an adjusting screw |01 which may be used to regulate the degree of rearward movement yof the regulating shoe in response to the tension of the spring 98. As shown in Fig. 8, there are formed on the outer face of the left side wall of this regulating shoe, graduations |08, cooperating with the pointer |09 to indicate the various positions of the regulating guide shoe. 'Ihese graduations are so arranged on this guide shoe that each willindicate the proper position of the regulating guide shoe for a certain denite type of hair cut. It is obvious that by exerting pressure of the finger grip |02 as` to rock the shaft. or stud |0I, the regulating guide shoe may be .pushedforwardly against the tension of the spring 98.v When this pressing force is released from the grip |02, the regulating guide shoewill snap back into its initial position which would normally be into a position so as to engage the end of the adjusting scr-ew |01.

In use, when the shaft 41 is set into rotation, the'cutter blade 35 will be reciprocated. At the same time the pulley 6| will be rotated to effect a rotation of the shafts 58 and 59. As the shaft 59 is rotated, the pressure plates will successively be brought into engagement with the cam 14 4so as to ride over, with a very slight clearance, the cutting teethv34 on the cutter blade 35. As vthese presser plates 61 move downwardly into position, they will press the hair to be cut into the teeth and as the presser plate continues to move rearwardly as the shaft 59 is rotated, the angularly turned edge 68 of the presser plate 61 will serve to convey the cut hair along the surface of the guard plate 11 and between the guide plates 15 until the hair is brought into contact with the rotating bristles or brush 83 which will serve to sweep them up-wardly and rearwardly along the face of the guard plate 11 beneath the comb or cleaning plate 84 which will serve to clean or comb the hair from the bristles or brush 83. Thus the brush 83 serves to clean the cut hair fro-m the presser plate 61 and the member 84 serves to clean the cut hair from the bristles 83. Asa succeeding quantity of the hair is conveyed upwardly, it will be forced outwardly through the rear of the cover 81 sliding along the angularly turned portion 18 of the guard plate. It will be noted that when the presser members engage the hair and press it into thel teeth of the clippers, the springs 69 are under tension so that as these presser plates 61 move rearwardly along the cam 14 and guard plate 11, they will be held in close engagement with the surfaces of these members by the tension of the springs 69. As the preser plate clears the Abrush 83, these springs will rockthe presser plates 61 on their mountings until the tongue 13 engages the ring 12. This is a violent movement and in order to absorb th-e shock and prevent undue noise, the ring 12 is preferably made of rubber or some yieldable material.

Before the clipping operation is started, the operator adjusts the screw |01 to move the adjusting shoe to the proper position so that the pointer |09 will register with the proper graduation |08 which represents the proper position for a particular type of hair out. The operator then grabs the casing in the right hand, with his thumb on the gripping portion |02, and then clipping is proceeded with in the usual manner.

For trimming the hair bordering upon the naked parts of the neck, the operator brings the lower front end of the machine into engagement with the border line. 'I'hat is, either the teeth of the cutter 24 or the comb teeth 91 will be brought into engagement with the skin of the head, depending upon the previous adjustment of the adjusting shoe which will be indicated by the pointer |09 on the graduations |08. Then the operator would coordinate the upward bodily movement of the machine on the scalp with the rocking of the machine upon. the adjusting shoe as a pivot, so as to obtain the proper variation of length of angle of cut. When the machine is rocked on the adjusting shoe as a pivot, the front end of the machine would, of course, be disengaged from the skin of the head, and the free ends of the longer hair, which would overlie the cutters when the front end of the machine was in engagement with the skin of the head, would be cut 01T, thus giving the scalp the a ipearance of a shade increasing in darkness upwardly.

In order to observe the result of the trimming, the operator would remove the machine from the head and force the adjusting shoe outwardly into its forward position shown in Fig. 3 and, while the adjusting shoe is in the forward position, smooth the hair by means of the comb teeth 91 in the ordinary manner. In this manner the operator proceeds around the head, always starting from the naked parts of the head and moving the machine upwardly' and angularly to the free ends of the hair.

'I'his machine may be used in all instances of hair trimming where the use of scissors and comb is normally required. Before using the machine, the operator would first thrust the adjusting shoe to its forwardmost position shown in Fig. 3 by exerting pressure on the nger grip |02, while holding the adjusting shoe in its forwardmost position by means of the thumb of the right hand. The combing teeth 91 would then be thrust into engagement with the scalp, directed against the normal inclination of the hair so that these combing teeth 91 would serve to raise the hair prior to cutting in the same manner in which the hair is ordinarily raised by the comb when the operator intends to use the comb and scissors for cutting purposes.

After the hair has been engaged with the combing teeth 91, the entire structure is then rocked on the adjusting shoe as a pivot, this adjusting shoe resting against the scalp. The combing teeth 91 would then comb the hair outwardly until the proper length of the hair to be cut ofl projects above the teeth 91. This can be readily observed by the operator. Thereupon the operator, while holding the adjusting shoe stationary on the head, would release the pressure on the finger grip |02 and allow the mechanism to ride forwardly on the adjusting shoe as a supporting base, until the cutting teeth are in their normal positions relatively to the combing teeth. As the cutting teeth reach the up-lifted hair, this hair will be pressed against the cutters by the presser plate 61 and thus the proper amount of upstanding hair cut off. Consequently the machine thus is used by the operator to perform with one hand what is ordinarily performed by the operator through the use of two hands when using the scissors and comb.

It is believed obvious that the teeth 91 of the adjusting shoe, after the adjusting shoe has been moved to its forwardmost position, may be used to serve all of the purposes and functions of a comb in smoothing or lifting the hair.

These teeth 91 are so arranged relatively to the teeth 33 which are formed on the stationary cutter plate 24 as to lie in alignment therewith so that the slots between the teeth 91 register with the slots between the teeth 33, thus a sticking of the hair between the comb and the lower cutter plate teeth 33 is prevented.

It is believed obvious that if an operator does not desire to use theadjustable features of this device, the mechanism may be used in the manner of an ordinary pair of clippers with the additional advantages of trimming the free ends of the hair and of cutting hair having an automatically operated hair conveyor which serves to convey the clipped hair from the teeth of the clippers.

While I have illustrated and described the preferred form of my invention, I do not wish to limit myself to the precise details of structure shown but desire to avail myself of such variations and modifications as may come within the scope of the appended claims.
