This vinvention relates to improvements in hair cutting devices kand the like, and has for its primary Object to provide a device j which can be self-operated with safety. However, the device is not limited to such self-operationl According to this invention I provide a hair cutting device comprising a handle, frame or structure,ia pair of cuttingblades adjacent. a comb, each cutting blade having a single cutting edge and the blades being adapted to cut by one or both of the blades being oscillated about a common pivot or joint, means for actuating said blade or blades, and adjustable gauging means, whereby the position ofv such blades relative to the hair operated upon can be adjusted.

According to another'feature of this invention, I provide a hair cutting device comprising a handle, frame or structure, a shaft mounted longitudinally ofthe said handle,

a movable cutting blade actuatedthrough the medium o f said shaft, a Xed blade adj acent said movable blade, the cutting plane A of the saidV blades being transversely disposed to the saidI shaft and the said frame.

According to a subsidiary feature of the` invention, the overall dimensions ofthe handle structure or vframe of the device is adjustable whereby the frame or structure can be increased or decreased in such dimensions to suit within given limitsl the require-` ments of an operator."

According to a further subsidiary feature of the invention, blade-actuating means are provided which means comprise an oscillatable shaft carrying a lever or finger-piece by which the shaft is adapted to beoperated.

Further features of this invention will become apparent as thisspecication proceeds.

In order that my invention may be clearlyV understood and more readily carried into practice, I have appended hereunto one sheet of'drawings illustratingthe same, wherein:

Figure 1 is a perspective View of adevice constructed according to this'invention; Figure 2 is a plan of the same;

" Figure 3 is a longitudinal part sectional view ofthe same; 'Y

f Figure 4 shows a detail of the appara-tus shown in Figures 1 to 3;

Figure 5 also shows a apparatus.

In the embodiment of my invention shown in the drawings 1 is a handle frame or strucdetail of the same ture which in plan is somewhat similar in shape to a capital letter Y. The handle frame or structure 1 is divided in its length to form two parts 2 and '3 one disposed within the other and both parts being slidable relative to the other. The part 3 is provided with a substantially vertical wall 4 around its edge and the part 2 is also provided with a wall 5.

rIhe wall 4 carries at'or about its center a fixed inwardly projecting screwed studi or spindle 6 on to which is adapted to screw a nut 7 mounted in the wall 5 of the ypart 2 of the lhandle structure 1 in a manner such thatJ it can freely rotate but is axially immovable-independently of the wall 5 of the member 2.` By turning the nut Y vvthe distance between the walls 4 and V5 can bey increased or decreased according to the direc-y tionV `in which the nut is turned and consequently the wholelength of the handle structure 1 may be increasedor'decreased to suit the requirements of any particular operator.

'To facilitate the holding of the apparatus a thumb strap 8 is provided through which the thumb of the operator is passed. ThisA thumb strap is attached to the part 2 of the handlefstucture by means of a nutandbolt 9 and a distance piece 10 placed between the thumb strap 8 and the bottom of the part 2 of the device. The part 3 of the handle structure is cut away at 11A (Figures 2k and 3) so` as to permit of this part' being freely movable without being interferedl Y with by the connecting'meansfor lthe thumb strap 8.

l The reduced-end 12 of the part 2 of the handle structure 1 Vis provided at a short distance from its 'extreme end with` an up` wardly proj ecting" member or plateV 13, and a comb plate 14 anda flxedcutting blade 15 are both attached to thisprojectinglmember or plate 13 by means of a screw 16 and a nut 17. The nut17 islof elongated type so as to facilitate operations upon it. The cutting blade 15 is arranged directly behind the comb 14.

The part 2 of the handle structure is provided with a further upright wall 18 which is arranged parallel to the wall 5 and at a distance therefrom. This wall 18 may form a continuation of the wall 5. In bearings provided in the walls 5, 18, and in a projecting part 19 of the fixed cutting blade 15 is mounted a horizontal shaft 2O arranged longitudinally of the structure 1 and at a right angle to the fixed cutting blade 15 which Vis disposed transversely of the handle structure.

An oscillatable cutting blade 21 is carried by that end of the shaft 20 which is adjacent the fixed cutting blade 15, and the latter and the oscillatable cutting blade are adapted to work together in the manner of the cutting blades of a pair of scissors, the oscillatable cutting blade being actuated through the medium of the shaft 20 as will be hereinafter described.

The oscillatable cutting blade 21 is screwed on to the stem 22 of a member 23 rigidly attached to the end 24 of the shaft 20 by means of a coupling nut or the like 25. The stem 22 of the member 23 passes freely through the lug 19 of the fixed cutting blade 15 and is then riveted over at 26; this construction is clearly shown in Figure 4.

The shaft 20 is oscillated by means of a finger-plate or piece 27 fixed on the shaft 20 by screws or equivalent means 28 and projecting from the shaft 20 to form a lever. The finger-plate 27 has a part 29 extending in an opposite direction from the shaft 20` to the main portion of the finger-piece and this extension 29 serves as a lever for releasing the shaft in case it should stick owing to hair becoming wedged between the blades of the device in operation.

The finger-piece is normally retained in a raised posit-ion by means of a spring 30 connected to a fixed part 31 of the portion 2 of the handle structure 1 and to a lever 32 carried by a sleeve 33 fixed on the spindle or shaft 2O between the walls 5 and 18. The sleeve may be secured in position by a setscrew 34 or by other convenient means.

The action of the spring 30 is limited by means of a pair of interacting stops 35 and 36, the stop 35 being carried by the shaft 20, whilst the stop 36, which may be adjustable, is carried by the part of the handle structure l.

The parts between the walls 5 and 18of the part 2 of the handle structure may be enclosed by a lid 37 hinged at 38 to the wall 5 and this lid may have a downwardly curved portion 39 whichserves as a deflector for hair which has been removed or cut.

In order that hair may be cut to a predetermined length, a gauge member 40 is provided. This gauge member is adjustable and comprises a substantially channelshaped member having two upright walls 41 and 42, the wall 41 being higher than the wall 42 and the latter is restricted in height to accommodate the shaft 2O and the lug 19 of the fixed cutting blade 15. The two walls 41 and 42 of -the gauge 40 are connected together by a horizontal portion 43 and this portion is provided with a pair of ears or members 44 which are doubled upon themselves and overlap the reduced portion 12 of the part 2 of the handle structure 1 and so form guides for this reduced portion. The reduced part 12 of the member 2 of the handle structure 1 is provided with a hole 45 and the horizontal part 43 of the gauge :member 40 is provided with la series of spaced holes 46 preferably six in number, and a pin or peg 47 carried at the end of a spring arm 48, adapted to pass through any one of the holes 46 and through the hole 45. The spring arm 48 is fixed to the part 2 of the handle structure 1 preferably by means of the studs or bolts 49 which attach the stop 36 to this member. A vulcanite or other suitable handle 50 is provided at the pin end of the spring arm 48 to facilitate the manipulation of the spring arm.

The gauge 40 is slidable on the reduced part 12 of the part of the handle structure 1 of the appliance and it can be locked in any one of a number of predetermined positions whereby the distance of the cutting blades from the surface being operated upon can be set to meet the requirements and consequently any desired length of hair may be cut.

The vertical edges of the walls 41 and 42 of the gauge member 40 are preferably enlarged and rounded as at 51.

To use the apparatus an operator takes it in his hand and places his thumb through the thumbloop 8 which is located beneath the appliance and passeshis other fingers over the appliance. The first and second fingers of the hand are preferably placed upon the finger-piece 27 and by these fingers this finger-plate is intermittently depressed. If the shaft 6 sticks with the finger-piece in the depressed position it is released by pressing on the extension 29 of the finger-piece. Manipulation of the finger-piece in the manner described causes the oscillatable cutting blade 21 to pass the fixed cutting blade 15 and these blades function similarly to the blades of a pair of scissors. The gauge 40 is set as required and the device is applied to the surface to be operated upon with the edges 51 of the gauge resting on this surface. Hair is passed between the prongs of the comb by sliding the device along the surface operated upon and the finger-plate manipulated. Hair thus passing through handle made up of a gripping section andV a body section mounted for sliding cooperation, means whereby the gripping section and body section may be relatively adjusted to meet the requirements of the operato-r,

a shaft mounted in the body section and terminally provided with a blade, a fixed cooperating blade carried by the body section, a plate secured to the shaft and projecting laterally therefrom to serve as a means for moving the shaft in one direction, and a spring for moving the shaft in the opposite direction whereby under finger pressure on the plate the shaft is oscillated to actuate the cutter carried thereby.

2. A hair cutting device comprising a handle made up of a hollow portion including side walls, said handle including a body portion slidably mounted between said side walls7 means connecting the hollow portion and body portion to permit relative adjustment of these portions, ashaft extending longitudinally of the body portion, a blade carried by the free terminal of the shaft, f

a second blade carried by the body portion for cutting cooperation with the shaft-carried blade, and means connected to the shaft for imparting an oscillating movement to the shaft and blade carried thereby.
