3 Claims.

This invention relates generally to a tonsorial device, and more particularly to a hair clipper adapted to be operated by hand.

It is the object of this invention to provide a hand operatedhair clipper adapted to operate in the same manner as a conventional scissors, but providing means whereby tonsorial operations may be more perfectly performed than by the use of a scissors.

A further object of this invention is to provide a hair clipper adapted to be operated by the fingers of ones hand, including a cutting blade reciprocating in a line perpendicular to the line of motion of said fingers in operating said clipper.

Still, a further object of this invention is to provide a hair clipper which is adapted to be used for perfectly tapering the hair in tonsorial operations at places heretofore unreachable by the conventional hair clippers.

A still further object of this invention is to provide a hand operated hair clipper of simple and economical construction, adapted for production in large quantities, and which will effectively and efiiciently discharge the functions for which itis designed.

Heretofore, hand operated clippers have been constructed with the blade moving in a plane substantially parallel to the motion of the operators fingers. These clippers were large and cumbersome and provided with complicated mechanisms for the mechanical linkages thereof, necessitating intricate and involved operations for the adjustment, dissembly and sharpening thereof. The present device eliminates all of these difficulties, and also by its novel arrangement of parts permits the use of clippers on portions of the head not heretofore reached by the ordinary clippers. Thus, the use of the present device will permit the safe use of clippers behind the ears, or close to protuberances, such as curls and the like, etc.

The present device also permits the hair to be clipped in any direction, a feat which was impossible by the clippers heretofore used, due to the constructions thereof.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention consists in certain novel features of construction, arrangement and combination of parts hereinafter fully described, illustrated in the accompanying drawing, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportion, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention. g

, For the purpose of facilitating an understanding of my invention, I have illustrated in the accompanying drawing, a preferred embodiment thereof, from an inspection of which, when considered in connection with the following description, my invention, its mode of construction, assembly and operation, and many of its advantages should be readily understood and appreciated.

Referring to the drawing in which the same characters of reference are employed to indicate corresponding or similar parts throughout the several figures of the drawing: I

Fig. 1 is a top plan view of an embodiment of the present invention in a closed position;

Fig. 2 is a bottom plan View of the device in an open position;

Fig. 3 is a sectional view of the device taken along the line 3-3 of Fig. 2; I

Fig. 4 is a sectional view of the cutting portion of the device taken along the line 44 of Fig. 1.

Generally, the'device consists of a finger portion provided with a fixed cutting blade, to which a movable cutting blade is linked and caused to slide over the fixed blade, hairs being severed by reason of being caught between teeth provided on both of said blades.

Referring to specific constructional details, the device is provided with the conventional finger loops Ill and H on the ends of arms l2 and [3. The ends of said arms I 2 and I3 are pivotally attached by the pin l4 through the common ends thereof opposite to the finger portions l0 and l I. Said pin I4 is provided with a head IS on one end thereof, and is further provided with a threaded portion IE on the opposite end thereof. Said threaded portion I6 is fixed in the blade I1, maintaining said blade immovable with respect to the arms I2 and I3.

Portions intermediate the ends of the arms l2 and I3 are provided with projections l8, which carry the pins l9. Said pins l9 pivotally attach links 20 to said arms l3 and I2 at one end of each said links 20, the opposite ends of both of said links 20 being pivotally attached to the movable blade 2| by means of the pin 22.

It will be seen that by reason of the linkage,

the spreading of the arms l2 and I3, as shown n Fig. 2, causes the distance between the pins I 4 and 22 to decrease, and since the blade member I! is attached to the pin- 4, and the blade member 2i is attached to the pin 22, said blade members Will move relative to one another and in a line perpendicular to the line of motion of the finger loops Ill and II.

The movable blade 2! is guided with respect to the fixed blade [1 by means of the slots 23 and 24 in said movable blade 2|. The slot 23 is guided by the pin [4, the members I? and 2! being urged together by the coil spring 25 mounted on the pin [4 at this point. Said spring 25 also serves to urge the ends of the arms l2 and [3 together against lateral movement with respect to one another and said pin I4, urging both of said ends towards and against the head [5. The slot 24 is guided by a pin 26, which is fixed in the blade member I! and which is provided with a coiled spring 21 for urging and maintaining the members 2| and I! in sliding engagement with one another.

Each of the blades l1 and 2! is provided along one of the edges thereof with cutting means for cooperation with one another, In the embodiment shown, said cutting means consist of teeth 28 on the member l1, cooperating with similarly placed teeth 29 on the member 2|. It is obvious that hair caught between the rows of teeth when the device is placed against a persons head or the like for tonsorial operations, will be severed by causing the blade 2! to move across the blade [1.

Thus, it will be seen how the device may be used to cut and bevel hair perpendicular to the line of motion of the operators fingers. It will also be obvious that the hair may be easily cut and beveled in a downward direction by simply reversing the sides of the present, device. The arrangement of the cutting portion of the device with respect to the finger operated portion makes this device especially effective in the cutting, trimming and beveling of hair in places inacces sible to the ordinary clipper.

It is believed that my invention, its mode of construction and assembly, and many of its advantages should be readily understood from the foregoing without further description, and it should also be manifest that while a preferred embodiment of the invention has been shown and described for illustrative purposes, the structural details are nevertheless capable of wide variation within the purview of my invention as defined in the appended claims.

I claim:

1. In a hand operated clipper, arms adapted to be spread and brought together commonly pivoted to a fixed cutting member, a movable cutting member adapted to move upon said fixed member parallel therewith and relative thereto, means linking said arms to said movable member for imparting thereto said parallel motion, said means comprising a pair of links each having an end pivoted upon said movable blade and the opposite end pivoted to one of said arms.

2. In a device of the character described, arms commonly and pivotally attached to a fixed cutting member, a movable cutting member linked to said arms and movable upon, parallel and relative to said fixed cutting member thereby, said linkage consisting of members each pivotally attached to one of said arms and commonly attached to said movable member.

3. In a device of the character described, arms adapted to be opened and closed commonly pivoted to a fixed cutting member, a movable cut ting member adapted for sliding on said fixed cutting member relative thereto slidably attached to said fixed cutting member, means linking said arms with said movable cutting member for causing said motion of said movable cutting member consisting of a pair of members arranged for exerting toggle action having a common end of each pivotally attached to said movable cutting member and the opposite end of each respectively attached to one of said arms, and spring means for causing the cooperation of cutting edges provided on said cutting members with one another, said spring means being arranged to urge said cutting members into intimate contact with one another during said sliding motion.

JOSEPH J. HOLLANDER.
