EPIFANIO V. N. TOMASULO, OF CINCINNATI, OHIO.

T 0 allwhom it may concern.

Be it known that I, EPIFANIO V. N. TOMA- sULo, a subject of the King of Italy, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Automatic Hair-Cutting Machines, of which the following is a specification, reference being had to accompanying drawings, forming part of this specification.

My invention relates to hair clippers, of the power driven type, and is more directly involved with the provision of a double cutter for this type of work.

It is ordinarily necessary for the barber to provide himself with two clippers, one of which is for fine, close, work and the other for work where close or fine cuttingis not desired. This duplication is avoided by my invention wherein there are two sorts of clippers combined in the same case, and conveniently set so that either of them can be used on the customer. I

It is one of the objects of my invention to provide a case for a double cutter of the character indicated which presents to the neck and head of the customer, a properly graded curve or convexity so that the operator can readily hold the structure in position to accomplish the length of cut that he wishes, and can easily guide and slide the device along.

It is another object to provide a single operating plate which works the movable toothed plates of both clipper units, and to impart oscillation to this plate in a simple and effective manner from a revolving shaft of the type ordinarily employed with such machines.

lt isanother object to provide a simple handle for the machines which handle is preferably used also as a mounting means for the operating mechanism of the oscillating plate above mentioned.

This handle is preferably also held in place by the same device that holds the upper portion of the machine casing, and both are simply mounted on the base portion, so as to be readily removed for clean ing, carrying with them the mechanism referred to.

Thus the lower plate of my casing, having the special convexlty referred to, serves to mount the fixed cutter plates, acts as a guide or bearing for the oscillatingplate. The upper portion or" the casing carrles the AUTOMATIC HAIR-CUTTING MACHINE.

Fig. 11 is a side elevation thereof.

Fig. 12 is an end elevation of the plate shown in Figs. 10 and 11.

In describing my device I will first refer to the base of the casing, as in the contours parts shown in Figs. 5

thereof reside an important feature of my invention.

As noted the base 1 (Fig. 2) and the base '1 (Fig. 4) both serve to support the entire mechanism of the device. Referring first to the 'base 1, it will be observed that it comprises sides 2, 2, transverse ribs 3, 3, and a central boss 4. y

The under side. of this casing base, is formed on a gradual oval curve having its apex at the central part thereof, and its transverse elements parallel. In width this portion is suflicient to take a bearing on the neck of the customerand not rock sidewise.

Extending from the outer limits of this gradual curve are more sharply upward turning portions 5, 5, in offsets of which the fixed cutter plates 6 and 6- are mounted. The cutter plates 6, and 6, are respectively fine and coarse at their toothed extremities 7, and 7, and they are so countersunk into is a detail vertical longitudinal secthe body of the portions 5 of the base that they form a straight line substantially tangential to the curve of the base up to the point of attachment.

1 Of the sharper curve it should be noted the extent of permitthat it is gradual to ting. a number of different angles resulting to the blade osition and wide enough to provide a wi e fulcrum for the tilting of the base against the head and neck of a customer.

The form in Fig. 4 having the base 1 corresponds in its contours and is similarly numbered to the parts shown in Fig. 2 except for the base 1 which is flat. T find that the former construction permits an easier general manipulation by the barber, enabling him to rock the device away from hair cutting position while he observes the work without lifting the body away from the head, or neck, and to rock it back again in a smooth and even manner. The rounded contour of the central elements of the said base are not, however, essential, and my construction in Fig. 4 will accomplish all the other advantageous features of the invention. i

The upper cover of the casing comprises a plate 8 substantially flat and resting on the sides of the base at the central portions, but turning up at the ends as at 9, 9, said ends being equipped with posts 10, 10, which are directed at an angle perpendicular to the angle of the fixed cutter plates on the base. This cover has a central aperture 11,

and preferably'is otherwise of unbroken surface so as to cover up the operating parts within the caslng. The body around the out out as at 12 to form a central aperture is post of the seat for the central hollow handle.

Held on studs 13, 13, suitably mounted in the fixed cutter plates, are the movable cutter plates 14,14 one being fine and the other coarse, to match the respective fixed plates. Slots 15 in the said movable plates permit of a sliding of said plates on the fixed plates thereby imparting to the teeth a clipping motion.

Hoods 16, 16, are provided which come ,down over the movable plates and press them with the desired degree of closeness against the fixed plates and hold them in place on the mounting studs. These hoods are set over the posts 10, by means of thumb nuts 17, which bear on the hoods through the medium of spring washers or. ,the like, as shown at 18.

These hoods are thus removable with the cover, so as to expose the movable plates without other manipulations, and without requiring a re-adjustment when the parts are re-assembled.

The .handle is of special form adapting it to the mounting of the operating mechaof this post end, having a bearing handle body comprises a hollow post element 19 for the operating worm 20 of,.

the flexible shaft 21. It has also a seat 22 for a worm wheel 23, that meshes with the worm, and a housing 24 to one side of the worm bearing portion forthe flexible shaft.

In this housing 24 is mounted a set screw 25 for engaging a groove in the end of the flexible shaft, to hold it in place'with the squared end thereof engaging within a socket 26, at "the end of the worm.

Running lengthwise of the machine and at the side the worm bearing portion is a plate 27 for grasping by the fingers of the operator, and a finger engaging tongue 28 extends laterally from this grasping plate 27.

At the opposite side of the handle body post, at the broadened upper end thereof is another grasp plate 29, and a thumb notch 30 formed laterally thereof.

A cap 31 is provided for, the handle which fits down over the upper end of the mechanism housing portion thereof, and a mounting post 32, secured in the central boss of the base passes up through the hollow post structure, and through the cap 31, a thumb nut 33 being provided for holding the cap down on the hollow post, and the hollow post and casing cover on the casing base.

Removal of this nut permits all of said parts to be lifted away as has been noted.

The worm wheel 23 is formed or mounted at the upper end of a sleeve 34 which is housed within the hollow body of the handle post, and bears on the mounting post. This sleeve carries, at its lower end an eccentric 35, which serves to oscillate the operating plate for the two movable cutter members.

This plate has a central portion 36 within 'which is an oblong opening or slot 37 which engages over the'eccentric and depending from the under side of the plate are lugs 38, 38, which slide in channels 39 formed on the ribs 3, 3, of the base. A convenient way of forming the lugs is to bend them down fr'omthe sides of the plate, at theends of the central portion thereof.

Extending from the said central portion of the plate at both'ends thereof are attenuated members or tongues 40, which enter slots 41, 41, formed inthe movable cutter plates, so that when the eccentric device carry with it in its oscillations the movable cutters.

Another way of mounting the operating plate as illustrated in Figs. 5-7 is to form it with a depending collar ortion 42, at

each end of the central portion and to set' hand for both cutting operations, he has.

merely to loosen the handle thumb nut and revolve the casing around to the desired position. The handle could be set at an angle tothe casing if desired for that matter.

I do not desire because of reference to specific mechanisms in the above description to thereby limit the claims that follow beyond their evident scope and the full range of equivalents to the mechanisms called for therein.
