HAIR CLIPPER.

A iplication filed March 13, 1923. Serial No. 624,697.

To all whom it may con-07cm:

Be it known that I, MICHAEL MAsoTTr, a citizen of the United States, residing at Schenectady, in the county of Schenectady and State of New York, have invented new and useful Hair Clippers, of which the following is a specification.

This invention is a device of the type commonly used by barbers in trimminghair.

Barbers clippers of the type now in general use are ordinarily provided with approximately straight cutting blades, which are moved relatively to each other by means of a pivoted handle actuated by the operator. In the operation of trimming hair with this type of clippers. the blades of the implement will closely follow the contour of the skull, but it is rather difficult, and in fact practically impossible for the barber to shape" the hair with the clippers contiguous to the clipped portion. Therefore, considerable time must be consumed in using the ordinary shears to shape the hair at the point where. theclipping has terminated.

The object of the, invention is to provide clippers of the type referred to, constructed toavoid the foregoing objections, by having provision whereby thecutting path of the implement may be so controlled, as to materially reduce the time necessary to shape the edge of the hair contiguous to a portion which has been clipped.

.The invention-will be hereinafter fully set forth and the claims.

, In the accompanying drawing Figure 1 is a plan view illustrating a pair of clippers constructe l in accordance with the invention. Figure 2 is a transverse sectional view thereof. Figures 3 and 4 are detail views of the comb plate and cutter plate respectively. Figures 5 and 6 are diagrammatic views illustrating the method of using clippers constructed in accordance with the invention.

Referirng to the drawing, 10 designates the comb plate, 11 the cutter plate, 12 the operating lever for the outer plate, and 13 the cover provided: with a fixed handle 14. The cover plateand the comb plate are. united by means of a tapered post 15, co-

The con-1h plate 10 is cut away as indicated at 17, to form raised bearing surfaces 18, which are accurately ground to provide bearing surfaces on which the cutter plate 11 slides.

particularly pointed out in Said comb plate is also provided with a circular hole 19, havinga slotted extension in which the post 15 is placed, a projection on the head of the post fitting into the slotted extension to prevent relative rotation of said post. At the rear of the plate 10, a second hole 20 is formed to receive a stud or projection from the 'cover 13, and a rectangular hole 21 is formed in the forward end of said comb plate, between the bearing surfaces 18, so as to receive a projection formed in the forward portion of the cover 13. The comb-plate 10 is constructed with a flat top surface and a convexed bottom surface the curvature of which is approximately continuous.

The cutter plate 11 is provided with a slot 22, through which extends the projection on the cover which projects through the slot 21 in the comb plate. This projection forms a stop to limit the reciprocation of the cutter plate in a manner well understod in the art. Leading from one edge of said slot 22 is a rearwardly extended offset recess 23, to receive a stud on the short end of the actuating lever 12, which lever is provided with a boss 24, through which the po'st15 passes. In this manner a pivotal support for said lever is provided. A suitable spring 25 encircles the boss 24,-and serves to return the cutter plate to a predetermined position when shifted upon the comb plate by means of the lever 12. The cutter-plate is fiat and approximately rectangular in plan View. The free ends of the levers or handles 12 and 14 are extended to a plane normally above the plane of the top of said cutter-plate.

The teeth 26 of the comb plate are curved upwardly as clearly shown in the drawing,

on an are extending from the forward edge of the comb plate and above the plane of the flat top of said plate.

The teeth 27 of the cutter plate 11 have their under faces curved to conform to the radius of the curvature of the top surfaces of the teeth 26, so that said teeth 27 may fit closely to the teeth 26 when the comb plate is recipr'ocated, In other words, the meeting faces of the two sets of teeth are curved the point A and finishes the clipping operati'onat the point B. Because of theflat straight surfaces of the plates the hair Wlll then have somewhat the appearance indicated along the line BD. It is then necof the forms in which it may be made, or

essary' to use the ordinary shears and comb and to spend a considerable period (fifteen to twenty minutes) shaping the hair along the line BC in order to prevent an unsightly appearance.

In Figure 6 is illustrated the method employed 1n using clippers with the curved blades. For instance, the barber will start his Work at'E, and to cut the hair evenly he moves the handle of the clipper in the direction indicated by the arrow 28. L Because of the curvature of the cutting teeth, he can readily shape 'the hair along the lines EFG or EHI or EJK, thus leaving but a. very small corner that has to be evened off with the ordinary shears and comb. Thus, by means of the. invention a great saving of time in the cutting of hair is obtained.

Having thus explained the'nature of the face being convexed, the forward edge of said, plate having teeth curved in continuation of the curvature of saidbottom surface and extending above the plane of the fiat top surface, a handle, means connecting the handle and the comb-plate in a manner to prevent relative movement of the handle and the plate, a flat cutter-plate slidably mounted on the flat top surface of the comb-plate, said cutter-plate having one edge provided with upwardly curved teeth complemental to and engagin the teeth of the comb-plate, a movable handle engaging the cutter-plate, and a pivot stud uniting said handles, the free ends of said handles being above the planes of botlrof said plates.

2. Hair clippers of the character described comprising a comb-plate, the top surface of said plate being flat, the bottom surface being convexed, the forward edge of said plate having teeth curved in continuation of the curvature of said bottom surface and extending above the plane of the flat top surface, a cover-plate having a projection engaging the comb-plate in a manner to prevent relative movement of the comb-plate and the cover plate, said cover plate having a fixed handle, a flat cutter-plate sli-dably mounted on the fiat top surface of the comb plat'e, said cutter-plate having one edge providedwith upwardly curved teeth complemental to and engaging the teeth of the comb-plate, said cutter-plate also having a slot through which the projection of the I cover-plate extends and an offset recess leading in from one edge of said slot, a springpressed movable handle having a stud eninvention and described an operative mangaging said recess, and a pivot stud unit- .ner of constructing and uslng the same, aling the comb-plate, thecover-plate and the though without attempting to set forth all all of the forms of its use, what is claimed movable handle, the free ends of said handles being located in a plane above the planes of said plates.

In testimony whereof I have hereunto set my hand.

MICHAEL MASOTTI.
