3 Claims.

My invention relates to new and useful improvements in hair clippers.

An important object of my invention is the provision of a hair clipper that has two cutting edges to facilitate the cutting of the hair.

Another object of my invention is the provision of a hair clipper having means integral therewith to cooperate with the cutting blades and to perform the same function as the comb ordinarily employed by a barber.

Still another object of my invention is the provision of a hair clipper that is simple in construction, efficient in operation and inexpensive to manufacture.

Other objects and advantages of my invention will be apparent during the course of the following description.

In the drawing, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a top plan view of a device embodying my invention,

Figure 2 is a vertical sectional view, taken on the line 2-2 of Figure l,

' Figure 3 is a longitudinal sectional view, taken on the line 3-3 of Figure 1,

, Figure 4 is a vertical sectional view, taken on the line I-4 of Figure 1, and

Figure 5 is a transverse sectional view, taken on the line 55 of Figure 3. i

In the accompanying drawing, wherein for the purpose of illustration, is shown a preferred embodiment of my invention, the numeral II] designates a lower cutting blade of substantially rectangular formation in plan and including a central longitudinal web I I which is formed with a plurality of spaced teeth I2 extending laterally therefrom and on either side thereof. The teeth I2 terminate a substantial distance from the rear portion l3 of the web II but extend flush with the forward end I4 thereof. The teeth I2 are of substantially triangular formation in side elevation having an upwardly sloping bottom edge I5 and a horizontal upper edge I6 which join to form a rounded point H. The upper edge I6 is provided adjacent the web II with a recess I8. In cross section the extremities of the teeth I2 are formed with a rounded bottom part having upwardly divergent sides and an oval top portion which merge into the rounded points H in a manner whereby no sharp or rough edges are evidenced. The horizontal face of the recess I8 is flat and the juncture thereof with the side Walls of the tooth form a sharp cutting edge.

The upper cutting blade I9 is substantially shorter than the lower blade 10, and is similarly formed with an elongated central web 20 having spaced teeth 2| extending laterally therefrom on either side thereof. The teeth 2I are adapted to register with the teeth I2 in the lower blade I0 and to be received within the recesses I8. The teeth 2| are of substantially paraboloidal formation in cross section and are provided with a flat bottom face 22 adapted to have a close fitting sliding engagement with the horizontal faces of the recesses IS. The posts 23 and 24 are threadedly carried by the web II of the lower blade I0 and extend vertically therefrom to be received by the elongated slots 24 and 25 in the upper blade I9.

The handle member 26 is formed with an angularly extending thumb support 21 and has the inner end thereof bent inwardly and downwardly as at 23 to terminate in a forwardly extending shank 29 which is bolted, or otherwise secured, to the rearward portion I3 of the lower blade III. The tubular member 30 is integrally formed on the handle member 26 and in the same longi-' tudinal plane as the shank 29 but elevated with respect thereto to lie in a horizontal plane above the upper blade I9. The tubularmember 30 is provided with a transverse inner closure wall 3| and an open outer end which is externally screw threaded to receive the cap 32. The actuating rod 33 is formed with a laterally extending shank 35 which is pivotally received by the rear portion of the upper blade I9, and a screw threaded bore 34 which receives the adjusting screw 36. The screw 36 extends rearwardly thereof through the end closure wall 3| of the tubular member 30, and has the head 31 thereof positioned within the tubular member adjacent the end cap 32. A coil spring 38 is interposed between the head 31 of the adjusting screw and the inner closure wall 3I of the tubular member to hold the actuating rod 33 and consequently the upper blade I9 in a fully retracted position.

The companion handle member 39 is formed with a finger ring 40 intermediate its ends, and the inner end 4| thereof is bent angularly inwardly as at 42, terminating in bifurcations 43 and 44 which embrace and are secured to the rearward end of the actuating rod 33 by the set screw 45. Bifurcations 46 and 41 are formed on the tubular member 30 and extend laterally and forwardly thereof to embrace the handle member 39 at the juncture thereof with the angularly bent portion 42 and effect a pivotal engagement therewith by means of the bolt 48.

The cover plate 49 is positioned above the central web 20 of the upper blade [9 and is formed with longitudinal fianges50 and 51 which engage the web at its point of junction with the teeth 2|. The posts 23 and 24 extend upwardly through the cover 49 and the thumb screws 52 and 53 are threaded thereon to engage the top surface of the cover. The vertical flanges 50 and of the cover support the same in superimposed relation with the upper blade l9 and-will impart a substantial resilient action to the cover in a manner whereby the thumb screws 52 and 53 may be adjusted to vary the degree of frictional engagement between the upper and lower blades I9 and I0. It may be seen that the resilient nature of the coverimpivotally carried by the said first-mentioned handle member and having a part pivotally connected to the said actuating rod; a rearwardly extending headed shank screw-threadedly carried by the said actuating rod and extending through the closure wall and into the tubular element of the said first-mentioned handle mem-' her; and spring means positioned within the tubular element intermediate the closure wall and the head of the shank, said spring means coacting with the said shank to hold same normally fully retracted therein, the said shank being adjustable to vary the tension of the'said spring parted thereto by virtue of the longitudinal H flanges and 5| will prevent a binding from being effected between the jaws'but willpermit a sliding frictional engagement between the cutting faces of the upper and lower teeth of the blades.v

Aslhereinbefore described, the upper .blade I8 is held in a retracted position under the resilient action of the coil spring 38, and it may be seen that upon manual actuation of the handle meme bers26 and 39, a reciprocating motion will be impartedto the actuating rod 33 which will reciprocally actuate the upper blade within: the limits of the'elongated slots 24 and 25. The extremities of the lower teeth l2 comprise comb teeth, and inasmuch as they extend laterally on either side of the lower web l I, the device in. its entiretymay be moved either upwardly or down-. wardly on the scalp. The ends I! of the teeth are blunted to prevent the same from breaking or cutting the scalp. In moving the device either upwardly or downwardly the groups of hair will be engaged between the ends of the comb teeth in advance of the line of cut, and will split fan-like into the inner portion of the teeth where a reciprocating movement of the upper blade [9 will sever; the same. It may thus be seen that the ends of the lower. teeth l2 will automatically perform the function which is ordinarily performed .by' the comb that the barber carriestin advance of the shear or clipper. Theypresent invention is particularly adapted to. produce theshingling ,cut,'but it is to be understood that it will-perform equally Well in cutting thelhair regardless of the type of cut desired.

Itiis gto'be understood that the form of my in vention, herewith shown and described, is to be taken" as a preferred example of the same, and that various changes in the size, shape and arrangement of parts may beresorted to without departing from the spirit of my invention, or the scope of the appended claims. vHaving thus described my invention, I claim: 1. Ina hair clipper. of the type having a lower blade formed-with a plurality of spaced teeth projecting laterally from thesides thereof and an upper blade slidably mounted on the said lower blade and being formed with spaced laterally projecting teeth adapted to cooperate with the teeth of the said lower blade in the cutting of means to regulate the ease with which the handlemember may actuate the said upper blade.

1 2. In a hair clipper of the type having a lower blade formed with a plurality of spaced teeth,

3, In a hair clipper the combination of alower blade formed with a plurality of spaced teeth,

projecting laterally from eitherside thereof, said teeth having inner recesses in their upper faces,
