My invention relates to improvements in attachments for hair clippers.

An object of my inventio-n is to provide a comb attachment for hair clippers adapted for having the comb swingably mounted whereby the comb may be moved toward or away from'the cutting blade when the clippers are in operation for gradually varying the depth of the cut of the hair.

A further object is to provide a comb attachment for hair clippers of the type referred to which embodies means for retaining the comb in a fixed position with respect to the cutting blade, whereby the hair may be cut to a uniform length when the clippers are operated.

A further object is to provide a comb attachment for hair clippers of the type referred to, in which the comb may be quickly and easily detached from the comb-retaining structure.

Other objects relate to various features of construction and arrangement of parts which will be apparent from a consideration of the following specification and accompanying drawing, wherein Figure l is a side elevation of an electric clipper and my invention connected therewith,

In the embodiment selected to illustrate my invention I make use of a conventional hair clipper 10 of the electrically driven type which is provided with a head 12 having a top plate 14 and a reciprocal cutting blade 16. The structure recited does not constitute any part of my invention, but sets forth the device with which my invention is adapted for use.

My invention comprises a comb-retaining member 18 having a pair of spaced apart side members 20 and 22 which are joined together by a connecting member 24 connected with the top portions thereof. The side members 20 and 22 have the lower ends thereof provided with inwardly extending flanges 26 adapted fo-r engaging the top and bottom sides of the plate 14 for connecting the side members with the plate. The iianges 26 are also adapted for properly positioning the side members with respect to the plate and cutting blade.

A fastening member 28 is formed for providing connecting portions 30 receivable in openings in the side members 20 and 22. The fastening member is adapted for engaging the rear edge of the plate 14 for retaining the comb-retaining member 18 in connection with the plate 14.

The side members 20 and 22 are provided with aligned openings 32. A comb 34 is provided with aligned projecting end portions 36 receivable in 70 the openings 32 for swingably connecting the comb with the side portions 20 and 22. A spring 38 is connected with the connecting member 24 and extends therebeneath for engaging the comb 34 for yieldingly retaining the teeth of the comb l5 in a spaced apart position'with respect to the lower end of the plate 14.

The opening 32 in the side portion 22 is recessed as shown at 40 for receiving one of the projecting portions 35` of the comb whereby the 80 comb may be removably positioned between and connected with the side portions 20 and 22. A retaining member 42 comprises a resilient strip of material having its lower end connected to the outer side of the side portion 22 and is provided 85 with an opening 44 therein for receiving a projecting portion 36 `of the comb for retaining the projecting portion in the slotted opening 40.

By moving the retaining member 42 to its dotted lineposition shown in Figure 3, the projecting portion 36 of the comb is moved out of the opening 44 in the retaining member thereby permitting the comb to be removed from the side portions. The side portion 20 is provided with a lug 46 which extends over and engages the comb 95 when the comb is swung to its outermost position for limiting the outward movement thereof.

An arm 48 is pivotally connected with the side portion 20 by a headed pin 50 and is provided with a lug 52 receivable between teeth 54 of a segment 100 56 connected with the side portion 20 for retaining the arm 48 in a selected position with respect to the side portion 20. The end 58 of the arm 48 is adapted for engaging the comb on the under side thereof when the armv is positioned as shown in Figure l for iixedly retaining the comb in its outermost position shown in Figure l. The arm 48 is of resilient material so that it may be sprung inwardly for moving the lug 52 out of engagement with the teeth 54, thereby permitting the arm to be moved to its dotted line position shown in Figure 1, or to intermediate positions at which time the comb 34 may be swung to its dotted line position shown in Figure 1 or intermediate positions.

In Figures 7, 8 and 9, I have shown another form of my invention in which the parts corresponding to that form shown in Figures 1 to 6 have been given corresponding numbers.

In this form of my invention, however, the connecting member 24 is dispensed with and instead a connecting member 60 is joined to the side portions at the lower ends thereof so that it will be positioned in juxtaposition to the plate 14, as clearly shown in Figure 9. In this form of my invention, however, the opening in the side portion 22 for receiving the projecting portion 36 of the comb is not slotted and the retaining member 42 is dispensed with. If desirable, however, these features may also be included in this form of my invention. The outstanding difference, however,

vbetween this form of my invention and that previously referred to is that the spring 38 is dispensed with and instead a coil spring 62 is positioned on one of the projecting portions 36 between the comb and the side portions 2G, and has one end 64 thereof extending through an opening in the side portion 20 and the other end thereof in engagement with the under side of the comb 34, thereby tending to normally retain the comb in the spaced apart position with respect to the plate 14 as shown in Figures '7 and 9.

In employing my invention the plate 14 is first inserted between the side portions 20 and 22 so that it is receivable between the flange portions 26. The fastening member 28 is then snapped over` the back of the plate 14 for holding the combretaining member in fixed connection with the clipper plate. The clipper is then held in the hand of the operator in a manner similar to that for holding a pencil and the teeth of the comb placed against the hair, so that the comb will be positioned nearly flat upon the head but at a slight inclination with respect to the head so that the comb may be swung in the comb-retaining member.

The clipper is moved from the top of the head downwardly for cutting the hair, the distance that the teeth of the comb are spaced from the plate determining the depth of the cut. If it is desired that the hair be cut a uniform length, then the arm 48 should be positioned as shown in Figure 1, for retaining the comb in the position shown in Figure 1, and preventing the comb from being moved toward the plate if excessive pressure is applied thereto during the cutting operation.

If, however, the operator desires to vary the depth of cut as the comb travels from the top of the head downwardly the arm 48 may be moved to its dotted line position shown in Figure 1, at which time it is positioned out of engagement with the comb so that as the operator exerts increasing pressure against the comb during its travel, it may be moved from the solid line position shown in Figure 1 to the dotted line position, at which time the hair will be cut relatively short.

'I'hus it will be seen that in utilizing my invention the hair may be cut to a uniform length, or cut to a gradually varying length from the top of the head downward. It will also be noted that if the operator desires to cut the hair beginning at the neck and moving the clipper upwardly, the clipper may be held in the hand so that the teeth of the comb point upwardly; as

the operator begins moving the clipper he may exert suflicient pressure thereon to move the comb to the dotted line position shown in Figure 1 at which time the clipper will make its shortest cut, and as the clipper is moved upwardly, the pressure against the comb may be gradually released, thereby decreasing the depth of cut so that the hair will be gradually cut longer as the clipper is moved upwardly.

When the operator desires to remove the comb such as for the purpose of replacing it by a ner or coarser comb, the retaining member 42 is moved to its dotted line position in Figure 3, at which time the projecting portion 36 of the comb may be swung through the slot 40 and clear of the side portion 22, at which time the other projecting portion 35 of the comb may be withdrawn from the opening in the side portion 20.

When it is desired to disconnect the comb from the side portions in the form of my invention shown in Figures 7, 8 and 9, either one or both of the sides 20 and 22 may be sprung outwardly so that the projecting portions 36 of the comb may be moved out of the openings in the side portions. It will, of course, be necessary to move i60 the end 64 of the spring out of the opening in the side portion so that the comb may be removed. It will be seen, therefore, that the side portions 20 and 22 in the form shown in Figures 7 to 9, are preferably constructed of a resilient material.

When the operator desires to remove the attachment from the clipper, he merely lifts the fastening member 28 by the offset portion 29 for moving the fastening member out of engagement with the end of the plate 14.
