Germany August 26, 1929 13 Claims. (Cl. 30-13) This invention relates to thinning shears and scissors, which may be employed in the operation of trimming and dressing ladies hair, and it consists in the novel features, which are hereinafter more fully described.

It has been found desirableby women-patrons of barbers and hairdressers establishments to have their hair thinned below a certain point of their length, whereby to more easily enclose the same by cloche hats and l,for aesthetic purposes.

One of the objects of my invention is to provide a perfected pair of hair thinning shears or scissors which will cut alternate strands of hair, leaving the remaining strands uniformly distributed, thereby producing a pleasing effect resembling that of naturally thinner hair.

Another object of my invention is to simplify and render easier the thinning of hair, thereby enabling the operation of hair 'thinning to be performed by a person of ordinary or average skill, without the necessity of having to engage for this work a specialist of the highest skill.

A further object of my invention is to reduce the time consumed by the operation of hair thinning.

Another object of my invention is to have said hair thinning shears or scissors designed for various degrees of hair thinning, as may be desired by individual. customers or patrons of the hair dresser or barber.

i further object of my invention is to have said .hair thinning shears or scissors designed for cutting alternate strands of hair of various thicknesses, as may be desired or considered more attractive.

A. still other object of my invention is to have the said improved hair thinning' shears or scissors of a design, which will admit the ready regrinding of the cutting edges thereof.

Another object of my invention is to have my said hair thinning shears or scissors of a design, which will cut alternate strands of hair and leave the remaining strands of hair in a perfect condition, to wit: they will not inutilate or injure the remaining strands of hair.

A further object oi my invention is to have my improved hair thinning shears or scissors eticotive, simple, durable and relatively inexpensive.

@ther objects and advantages will hereinafter appear.

I attain these objects by the hair-thinning `shears or scissors, several forms of which are illustrated in the accompanying drawing, or by any mechanical equivalents or obvious modifications of the same.

In the drawing, f

Fig. 1 is a side elevation oi one form oi my hair thinning shears or scissors, showing also a tress of hair in the operation of thinning the same by the above shears or scissors.

Fig. 3 is a detail of-another pair of oppositelydisposed projections or teeth on shears or scissors, havinga different design.

Fig; 4 is a view in elevation of a tress of hair before being thinned;

Fig. 5 is a view in elevation of a tress of hair after it has been thinned by my improved shears or scissors.

Fig. 6 is a side view in elevation of a cheaper modilcation of my thinning shears or scissors.

Fig. 7 is a fragmentary side view in elevation, showing a modified form of a blade of rny thinning shears or scissors.

Similar numerals refer to similar parts throughout the several views:

il, 12 represent the two blades or legs of my improved hair thinning shears or scissors, which have their cutting edges provided with alternate recesses 13, ifi, which are backed by

blunt edges

17, 18 and alternate tooth like

projections

15, 16.

The recesses 13 and M on each of said blades ll and 12 maybe similar in outline; but the teeth l5 on the blade il may preferably differ in outline from the teeth 16 on the-'blade 12, as shown in Figs. i and 2.

'In the forni oi' my shears or scissors shown in Figs. l and 2 the teeth l5 on the blade l1 have rec tilinear. cutting edges, and the teeth i6 on the blade l2 may have cutting edges provided with a receding outline. which may be either tf-shaped as in Figs. l and 2 or concave as in Fig. 7.

The receding outline of the cutting edges serves to keep the strand of hair, or any part thereof, which is to be out, from slipping olf of the cutting edges.

In the forni of my thinning shears or scissors shown in Fig. 3 the teeth i6 on both blades il and l2 are provided with cutting edges, which have a V-shaped outline.

In the form of my thinning shears are scissors shown in Fig. 6 only one or" the blades 22 is provided with. a cutting edge having therein recesses and projections, and the other blade 2l is pro vided with a straight cutting edge of standard shape, which cooperates with the receding outlines of the cutting edges of the projections on said blade 22.

My improved shear-sor scissors may be provided with pairs of looped handles of standard design and they may be operated in the usual manner.

A pair of oppositely disposed stops 211 and 25 are provided on said handles, to limit the amplitude of the motion of the blades of the shears or scissors towards each other, whereby to prevent will undue compression of the strands of hair which are enclosed by the above described recesses.

In the operation of my improved shears or scissors alternate strands of a tress of hair are intercepted by the said

cutting edges

15 and 16,l

compress the strands of hair, while others of

said edges

17 and 18 barely touch the strands of hair in said recesses 14.

Many changes may be made in the details of my hair thinning shears or scissors without departing from the main scope of my invention, and parts of my invention may be used without other parts.

I do not, therefore, restrict myself to the details as shown in the drawing; but Ivintend to include also all mechanical equivalents and obvious modifications of the same within the scope of my invention.

I claim as my invention and desire to secure by Letters Patent:

1. A scissors including a pair of legs having coacting spaced cutting edge portions, and interposed spaced non-cutting portions which are non-cutting when the blade is moved from open to completely closed position.

2. A hair cutting scissors comprising a pair of pivotally movable legs having opposed coacting spaced cutting edge portions, said legs having therein opposed recesses between said respective portions, said recesses being non-cutting in all positions of the legs.

3.A pair of shears consisting of pivoted cutting blades having operating handles with stop means for limiting the closing movement of said blades, one of said blades being formed with a series of longitudinally arranged cutting teeth with intervening recesses, each of said teeth being tapered on opposite sides and provided with V- shaped notches in their outer ends, and the other blade having a tapered portion projecting along the side of said teeth and having a straight cutting edge intersecting the teeth when both blades are closed, and spaced from the bases of said recesses to provide openings to receive uncut hair.

4. A pair of shears including two blades pivotally connected in crossed relationship; one of said blades having a series of spaced teeth projecting toward the other blade and the ends of said teeth being adapted to receive hairs to be cut while hairs not to be cut pass between said teeth, the other blade having a straight cutting edge adapted to shear on the sides and ends of said teeth as said blades are closed together for cutting the hair on the ends of said teeth, the cutting edge of said other blade being spaced from the bottoms of the spaces between said teeth, ior the purpose described. y

5. Means for thinning-out strands of hair and the like, comprising a blade having alternate teeth and depressions lengthwise thereof, and a cooperating shearing blade adapted to close over the toothed blade, the portions of the second blade which aline with the teeth being adapted to cut-ofi those strands which are in alinement with the teeth, and the portions of the second blade which aline with the depressions being spaced from the bases of said depressions when the blades are closed, so that those strands which aline with the depressions are received in said spaces without being cut by the shearing action.

6. A pair of shears having each blade formed with deep notches in its cutting edge spaced apart to form cutting teeth, the free edges of which are sharpened, the teeth of the two blades cooperating with each other to produce interrupted shearing action whereby the hairs which come between the teeth are severed while those hairs in the notches are not severed.

7. A pair of shears having each blade formed with deep notches in its cutting edge spaced apart to form cutting teeth, the free edges of which are sharpened, the teeth of the two blades cooperating with each other to produce interrupted shearing action whereby the hairs which come between the teeth are severed while those hairs in the notches are not severed, the teeth on one blade having V-shaped notches in their cutting edges, the walls of which are beveled to provide cutting parts at the free end of each tooth.

8. A hair thinning device comprising a pair of blades pivoted together to move toward and from each other, said blades having short cooperating hair-cutting portions spaced along the blades, and short noncutting portions between the cutting portions, said non-cutting portions being noncutting in all relative positions of the blades.

9^. A hair thinning tool comprising a plurality of small cooperating hair-cutting devices spaced slightly from each other along an extended line, and adapted to cut small strands of a layer of hair; said devices being sufficiently spaced to leave short non-cutting spaces between the cutting devices; said non-cutting spaces being non-cutting recesses having non-cutting edges leaving small strands of said hair spaced and uncut across said layer, while the cutting devices cut intervening small strands, thereby thinning hair by a new mode of operation and accomplishing the new function of evenly thinning the hair across a thin layer of hair.

10. A hair thinning tool comprising a plurality of small cooperating hair-cutting devices spaced slightly from each other along an extended line, said devices being suiciently spaced to leave short-non-cutting spaces between the cutting devices and loosely holding strands of hair uncut in said spaces in all operative positions of the device and preventing such strands from moving to the cutting portion of the devices.

11. A hair thinning tool comprising a plurality of small cooperating hair-cutting devices spaced slightly from each other along an extended line, and short-non-cutting means between the cutting devices; said non-cutting means holding small strands of hair spaced from the person and away from said cutting devices, said means being noncutting at all operative positions of the tool.

12. A hair thinning device comprising a pair of elongated members movable laterally relatively toward and from each other, said members having short cooperating hair-cutting portions spaced along the members and, short non-cutting portions between the cutting portions; said non-cutting portions having only non-cutting edges.

13. A hair thinning device comprising apair of blades movable toward and from each other, said blades having short cooperating hair-cutting portions spaced along the blades and short non-cutting recesses between the cutting portions; said recesses being non-cutting in all closing positions of the blades.
