6 .Claims.

My invention relates to improvements in shavlng devices and the like and has 'for its primary object to provide a device for cutting whiskers or other hair from the smn without injury to the skin and without the use of water. soap.

lather, or other preparations applied to the skin or hair.

One important object of my invention lies in the provision of a cutting head consisting of a fixed or stationary cutter member and a movable cutter member associated therewith and on the olnitside thereof for direct engagement with the s n. I I

Another object of my invention lies in the provision or a cutting head from which the cut hair falls readily and freely, thereby eliminating the necessity for dismantling the head for cleaning it.

V A further object lies in the provision of a cutter head of few parts, simple and economical oi manufacture, easily assembled, andrequirlng a minimum of care and attention.

More specifically'my invention includes a fixed member provided with cutting teeth and with a groove or channel disposed longitudinally of the fixed head and at right angles to the cutting teeth, and a movable reciprocating cutter member disposed in such channel and provided with teeth lying directly upon' the upper or outer surface of the teeth of the fixed member torreciprocation thereover and in contact therewith,

the reciprocating cutter member being adapted to engagedirectly against the skin.

Still another object lies in the provision 01" with handle embodying my invention.

Figure 2 is a detail and partly broken view of the cutter head and handle in assembled relaion- Figure 3 is a side view of improved cutting head, certain parts being broken away for clear-- ness of illustration and to show the cooperation between the head and the actuating part for the movable cutter.

Figure 4 is a top plan view 01' the cutter head. Figure 51s a detail perspective view 03 the portion of. the cutter head. I I

Figure 6 is a detafl perspective view of the movable cutter member.

Figure 7 is a detafl perspective'end view or the handle or carrier to which the cutting head is attached and illustrating the actuating member 5 for the movable cutter.

Figure 8 is a'detailend view of a modified arrangement of the fixed andmovable cutters.

Although my invention has been referred to as a razor for use in shaving whiskers lrom'the face. 10 it will be clear that the same is equally adaptable for cutting longer hair than whiskers and may be used as a clipper for that purpose.

The reference character I designates generally a handle which may be of any suitable design and 1 size and is provided at one end with a channel or recess 2 adapted to receive the cutting head 3. The handle may enclose an electric motor or other power device adapted to oscillate longitudinally of the recess 2 an actuating arm 4 extending from within saidhandle into said recess, for operative engagement with the cutter in a manner to be described.

The particular type and design of electric motor or other mechanism ioroscillating the actuating 25 arm 4 forms no part of this invention'and it will. 1 of course, be understood that the size and design of the handle I will be such as to properly acconimodate the particular power operating mechanism used. I

The cutting head consists oi the fixed member 3 which is preferably a solid block substantially rectangular in shape and provided with a groove or channel 5 extending from end to end longitudinally through the block adjacent its upper side. The block 3 is provided on its underside and centrallythereoi with an opening 6 communicating with the groove 5 and 01 sumcient sizeto receive the actuating member 4 and permit oscillation thereof within such opening 6 and roove 5.

The block 3 is received withlnthe recess 2 on the end of the handle and is provided adjacent; one end andon its underside with a notch-1 I adapted to fit over-and engage 9. lug 3 provided across one end 01' the recess 2. of the handle. This interlocking arrangement prevents longitudinal movement of the cutter block on the handle. A set screw 9 is also provided on the end of the handle and adapted to engage against the side of the cutter block 3 whereby to lock the cutterhead in position on the handle. Obviouslyloosening this set screw 3 permits the ready removal of the cutter head trim the handle ii desired. :rne sides of the fixed cutter block 3 are beveled inwardly from a point spaced above the bottomoi 55 the block to e point adjacent the upper side thereof, as at it Adjacent the upper side, the sides are again beveled outwardlyv as at H. These upper parts of the fixed'head I, on opposite sides slots II. The slots II are preferably of a depthat least equal to the width of the beveled portion ll of the block. It may be said here also that the outer ends of the teeth is are polishedsmooth, so that they may be moved over the skin without injury or unpleasant feeling thereto. The side edges or corners of the teeth I! extending from the outer ends thereof inwardly to the channel I are left perfectly square and sharp as such edges constitute the cutting edges of the Adapted to be slidably received within the channel' I of the fixed block I, is a movable cutter as block II, of a length slightly lessthan the length of the fixed block I and ofsuch a size as to provide aclou fit within the channel I though permitting free and easy reciprocation therein. The

top side II of the cutter block II is wider than the channel I and extends on either side thereof to a point Just short of the ends of the fixed cutter teeth II. This top side is provided with.

. o against-it. The grooves l1 and teeth II are pref-z erably of the same widththough not necessarily..-

, Likewise the grooves I! and teeth II ofthe fixed block land the grooves l1 and the teeth- II of the movable block II are preferably of substanjtially the samewidth, though not necessarily;

/ The underside of the top portion II of the movable cutter II. namely, the underaides of the teeth II extending outwardly on-either side of the block.

II, are formed perfectly fiat and smooth and are ;adapted to lie directly upon and in contact with the upper sides of the teeth II of the fixed block. The ends of the teeth II of-the movable cutter may also be slightly beveled or pointed to more position and with its ends located evenly within theendsof the fixed block I. In this position readily receive the whiskers or hair.

55 The teeth II of the movable cutter are groun or otherwise formed very thin, particularly adiacent their ends when the cutting action takes place. These teeth II at their ends are preierably of a thickness on the order of .004 or .005. As shown, the ends of the teeth II are formed slight- 1y thinner than the middle or central portion ter block II .will be' reciprocated longitudinally within the channel I: The amount ofmovement is very slight, it being merely necessary to move 75 the teeth II of the movable cutter a distance sufcutter member instead of lying dir ficient to cause their lowermost side edges to alternately pass over and away from the adjacent upper side edges of the teeth is of the fixed cut ter block. The total extent of the movement of the cutter II is within the confines of the length 5 of the'fixed block I. Y

The-cutter block II is provided below the teeth II with elongated slot'll within which is disposed a light leaf spring 22. The sides of the fixed block I areprovided with aligned onenins l0 23 registering with the elongated slot II and through which passes a pin 24 adapted to engage with the upperside of the spring 22 when the movable member II is centrally positioned within the block I, exerting a tension on the spring s possibility of the instrument pinchingor cutting the skin.

InFigure a is shown a slightly modified men '25 of cutter and in which 3-a represents the fixed cutter block within which is longitudinally reciprocable the movable cutter member lI-a. In this form the cutter teeth iI-a of the inpvable upper fiat surface of the fixed member are set down within a groove or recess 24 formed in the upper sides of the fixed cutter. member H, the teeth lI-a of suchfixed member being recessedto receive the teeth of the movable cutter memas assembly and operation of cutting device, is as follows; v

In assembling the head. the movable block II is-,first inserted within the channel I of the fixedbiock 3 and slid thereina distance sufilcient g tobringtheendofthe'slotll inthemovable block into alignment with the openings 2:. The pin 24 is then inserted through theopenings l8 and through the slot II at its end and at ajpoint where the spring 2! lies against the bottom edge 50 A of the slot il whereby to permitiree insertion of the pin II through such slot. The movable. cutter block II is then slid inwardly to central the pin 24 nowengages the central raised portion of the spring, thus resiliently holding the teeth of the movable cutter member down into fiat engagement with the upper surface of the teeth'of the fixed member. The assembled head so is now placed in the groove or channel! in the end of the handle, thenotch I cumin: over the lug I and the actuating lever I extending throughtheopeninglofthefixed upwa block and into the recess II of the movable cutter e5 block. The set screw I is now tightened to rigidly hold the-head in-position on the handle and the device is ready to use. g

Whenthe actuating arm I oscillates in a direction longitudinally of the head and of the channel I, by any desired type of electric motor,

back and forth over the teeth i3 and slots I: of the fixed member 3. When the cutter member is placed against the skin and moved thereover during the reciprocation of the cutter IS, the hair or whiskers. are guided into the slots l2 by the ends of the teeth i3 and into the slots i1 between the teeth It of the movable cutter. whereupon they are cut by the underside edges of the teeth l8 as the same pass over and in contact with the upper side edges of the fixed teeth i3.

As fast as the whiskers and hair are thus out. they drop downwardly through the slots [2 on to the beveled sides i0'of the fixed block from whence they can easily be wiped or blown.

The only sensation in the use of this shaver is a very pleasant slight vibration to the skin caused by the rapid reciprocation of the cutter member.

It will be understood, of course, that changes may be made in detail without departing from the spirit and scope of my inventiomsuch as for instance. the varying of the distance between the edges of the cutter member teeth and the edges of the fixed member or the angle and depth of the be eled side portions I0 and ii. I do not limit myself, therefore, to the exact form herein shown and described other than by the appended claims.
