3 Claims.

'Ihis iventiori relates to an attachment for the conventional hair clippers of the type embodyi'iig a pair -of relatively reciprocable abutting vtoothed blades, foi the purpose of guiding the end portions 'of 'long hair between the teeth 'of the cutter blades.

An object of the linvention is to provide a hair "gidig attachment for hair clippers whereby the latter may be 'readily adapted for use in trimming long hair; it ordinarily being difiicult to manipulate hair Iclippers in hair trimming operations because the 'cutting edges of the clipper teeth extend to the tips thereof so that a cutting "'a'ctioi is affeted immediately `on engagement of the hair by the clippers.

particular 'object of the invention is to proi/id'e a 'hair guiding toothed extension to the leading edge of the c'onventional hair lclippers which will function to separate and break up clumps `lof hair in la fashion to effect a distribution of the hair between the tips of the cutting teeth yof 'the clipper as the latter is advanced relative t'o the hair and also to provide a construction in the attachment whereby it may be readily applied to and easily removed from the fixed lower clipper blade 'and be securely held in place thereon solely by a clamping or gripping 'action thereby obviating the use of supplemental pins or screws or the like, and also obviating any alterations or changp es in the clipper construction in order to adapt it for application bf the attachment.

further object is to provide an attachment 'of the above 'character which may be slipped in and out of engagement with a clipper blade and when applied be held in wedge engagement with the ends of the blade together with snap engagement with the rear margin of the blade in such ina-'nner to securely retain the attachment in place and hold it in a positive fashion against accidental movement relative to the clipper blade so as to maintain the hair guiding teeth of the attachment in proper alignment with the cutting teeth of the clipper. y

A further `object is to provide an improvement in hair guiding attachments for hair clippers which maypreadily be formed in one piece of 'sheet material.

With the foregoing objects in view, together with such other objects and advantages as may subsequently appear, the invention resides in the 2 'parts and in the combination, construction and arrangement of parts hereinafter described and clailrie and illustrated by way of example in the accompanying drawing, in which:

Fig. 71 is a perspective view of the attachment,

Fig. 2 is a plan view,

Fig- 3 is a rear elevational Iview,

i yis aside view,

Fing'. 5 is a viewinjside elevation of the cutting head of a pair of clippers showing the attachment as applied, Fig'. 6 is 'a View in transverse section of th'e lower ii'red cutting 'blade of a hair clipper showing the attachment as applied, and illustrating ln dotted lines the manner of effecting removal of 'trie attachment, and y Eig". v"7 is a perspective view of a fragmentary portion tif the hair guiding attachment showing the teeth thereof spaced apart in a skip-tooth arrangement. l u

Referring to the drawings more specifically A generally Ithe cutting head of a co'nventioiial hair 'clipper which embodies a fixed blade relatively slidabl blade C reciprocally 'll'lonted and slidably supported on the upper face of the hired blade. AThe forward vedges of 'the clipper blades B and Cv are formed withv hair cutting teeth D and E. The lower faces of the t'eethl'lj are inclined upwardly from the iiat underside IF 'o'f the blade B to the outer ends of the teeth. The blade B is characterized by having a longitudinal ytlafnsversely inclined edge a. 'on the underside of its rear portion. A

l Th'epresent inventin resides in a hair Vguiding attachment for the lower toothed blade B which embodies :a plate portion 1'! adapted to averli@ the underside of the nat face F 'of the bladeB irom the forward edge of which plate (entends an upwardly inclined toothed plate por'- tion 8 arranged to underlie the inclined und-er- "s es f teeth D fand to conform thereto in close g'contact therewith; the plate portion 8 being n'frmed with'a iSeries vof hair guiding or feeding teethl '9 which 'protrude a short distance beyond 'me tips of the teeth D and n pf the clipper. The teeth -9 may 4be spa-ced any suitable distances apart, bein'g lgenerally spaced in accordance with the spacing "of the teeth of the hair clippers, but not necessarily so since there are occasions where it is desirable that the spacing of the teeth may be either more or less than that of the clipper teeth.

Formed on each end of the toothed plate 8 are outwardly projecting flanges I and II which are tapered longitudinally to conform to the taper of the teeth D at the ends of the clipper blade B which flanges are provided with inturned lips I2 and I3 respectively on the upper margins thereof. The lips l2 and I3 are adapted to protrude over the upper face of the end teeth D in abutting relation thereto so as to coact with the inclined plate 8 in affecting wedge engagement between the attachment and the end teeth of the blade B.

An important feature of this invention resides in forming the plate 1 on the margin thereof opposite the juncture with the toothedplate 8 with a resilient tongue having its outer end adapted to be engaged with the rear edge a of the clipper blade B. As here shown a pair of such tongues I4 and I5 are provided which are spaced apart and terminate in upstanding outwardly inclined flanges I6 and I1, terminating in outwardly projecting flanges I 8 and I 9; the inclined walls of flanges I 6 and I1 being adapted to engage the edgea of the blade B as particularly shown in Fig.

The flanges I0 and II with their associated inturned lips I2 and I3 form open ended opposed tapered channels 20 and 2| the large ends of which are presented toward the plate l. In applying the attachment the side margins of the teeth D of the plate B are positioned in engagement with the flanges I0 and II and lips I2 and I3 by inserting the end teeth D in the large ends of the tapered channels 2l! and 2l and advancing the attachment and blade B relative to each other until the upper and lower margins of the teeth are snugly seated between the lips I2 and I3 and the plate 8. When this occurs the inclined anges I6 and I'I will snap into engagement with the edge a of the blade B as shown in Fig. 5. The attachment will then be securely held in place on the blade B.

When it is desired to remove the attachment the gripping flanges I6 and I'I and the tongues I4 and I5 are moved downwardly as indicated by the dotted lines b in Fig. 6 to dispose the grips out of engagement with the edge a whereupon the side grips formed by the flanges IU and I I may be slipped outwardly and withdrawn from engagement with the end teeth of the clipper. In order to facilitate disengagement of the flanges I6 and I'I from the edge a the portion of the inclined plate portion 8 adjacent its intersection with the plate portion 'I is formed to project downwardly from the inner ends of the lower inclined faces of the clipper teeth D when the end teeth D are snugly seated in the tapered channels 2li and 2l so that the plate portion 1 and the tongues Id and I5 will extend in slightly spaced relation to the underside of the blade B and thus be out of contact therewith and also space the rear edge of the plate portion 'I from the blade B. By this arrangement the marginal portion c of the plate 'I and the contiguous portions of the tongues Ill and I5 are projected so as to be readily engaged by the tip of the thumb or a linger and a forward thrust imposed on the attachment so as to cause the inclined flanges I'I to ride over the inclined edge a and thus free the tongues I4 and I5. The clearance afforded between the plate portion 'I and the underside of the clipper blade B facilitates withdrawal of the end teeth D from the channels 2U and also facilitates insertion of the end teeth in the channels in applying the attachment.

In the operation of the invention when the attachment is applied to the clipper the protruding ends of the teeth 9 will on being advanced into the hair to be clipped act to separate the hair and effect feeding of separated groups of hair to the cutting teeth of the clipper, thus enabling the operator of the clipper to trim the ends of the hair in a fashion ordinarilyl accomplished by the use of comb and shears inA barbering operations.

In the construction shown in Figure 1, the teeth 8 of the hair guiding attachment are shown as of a width and spaced apart such as to correspond to the teeth and spaces therebetween of the clipper blade to which the attachment is to be applied. Fig. '7 illustrates another construction in the attachment in which a wide spacing is afforded between adjacent teeth in what is known as a skip-tooth arrangement where every other tooth of the ordinary construction shown in Fig. 1 is eliminated. This arrangement is found advantageous where it is desirable to feed the hair to the clippers in greater quantity and faster than can be effected by closer spacing of the teeth.

While I have shown and described a specific embodiment of my invention I do not limit myself to the exact details of construction set forth, and the invention embraces such changes, modications and equivalents of the parts and their formation and arrangement as come within the purview of the appended claims.

I claim:

l. A hair guiding attachment for hair clippers comprising a toothed plate, an upstanding longitudinally tapered flange on each end of said plate, an inturned lip on the upper margin of each of said flanges, and at least one spring tongue carried by and extending rearwardly on said toothed plate having an upstanding ange thereon.

2. A hair guiding attachment for hair clippers having a fixed blade formed with cutting teeth including end teeth, a toothed plate, open ended longitudinally tapered channeled members on the ends of said toothed plate adapted to receive the end teeth of the clipper blade in wedge engagement therewith and means on said toothed plate for releasably gripping the rear portion of the clipper blade.

3. A hair guiding attachment for hair clippers having a, fixed blade formed with cutting teeth including end teeth, a toothed plate, open ended longitudinally tapered channeled members on the ends of said toothed plate adapted to receive the end teeth of the clipper blade in wedge engagement therewith, a rearwardly extending spring tongue on said toothed plate, and a blade gripping flange on said tongue.
