TAPER FEEDING HAIR CLIPPER COMB Filed Sept. 27, 1937 2 Sheets-Sheet 2 "if wwmm INVENTOR Jase 17k Cwmra'c Patented Jan. 16, 1940 UNITED STATES PATENT OFFICE 4 Claims.

Thisinvention relates to new and useful improvements in a taper feeding hair clipper comb.

The invention has for an object the construction of a feeder for a hair clipper which is adapted to so feed the hair clipper that it is capable of cutting ones hair in a smart and neat taper.

More specifically, the invention proposes the provision of a spacer comb in conjunction with the comb plates of the cutter, and arranged in a manner so that the distance of the spacer comb maybe readily varied from the combplates of the cutter to control the taper of cutting of ones hair.

Still further the invention contemplates the provision of a handle which may be conveniently moved by ones finger and which is capable of extending the spacer comb to various amounts in direct relation to which the handle is moved.

Still further the invention proposes to characterize the spacer comb by the fact that it is provided with rack elements engaging slots in the stationary comb of the hair clipper, the provision of a shaft with gear segments meshing with racks, and the arrangement of mounting the handle on the shaft by which the gear segments and racks, and so the spacer comb, may be controlled.

Still further the invention contemplates associating a spring in a specific manner with turnable shaft so that normally the spacer comb tends to maintain a retracted position.

Still further the invention proposes. several modified forms by which the spacer comb may be extended or retracted to various degrees as required.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

A spring [6 is associated with the movable handle M in a manner so as to normally extend the handle I4 so that the handles [3 and I may be moved together to cause the movable plate to move. Further details of the construction of thehair clipper will not be given in this specification since they form no part of the'invention and are of standard construction generally known.

In combination with the hair clipper specified, there is a spacer comb 18 which engages over the said comb plates Ill and H and which is slidably mounted on the stationary comb H by reason of rack elements I9 extending from the side edges of the spacer comb and slidably engaging in slots 20 formed in the end portions of the stationary comb ll. These slots 28 are arranged at an inclination to correspond with the inclination of the rack elements l9 (see particularly Fig. 1) whereby when the rack elements H! are extended the spacer comb will be correspondingly moved, as for example shown by the dot and dash lines I8 in Fig. 1.

A shaft 2| is turnably mounted through the cover plate 12. Gear segments 22 are mounted on 'the shaft 2| and engage the teeth of the rack elements I9. The handle 23 is mounted on the shaft 2| by which it may m manually turned by ones finger for moving the same.

The rack elements l9 and the corresponding parts may be of any suitable size to insure a smooth operating action.

The spacer comb l8 comprises a plate element ilar to Fig. 6 but of the invention.

pper, according to hair clipper having cooperative with a stathe rear end portion of l8 from which a plurality of teeth l3 project. These teeth are bent so as to engage over the teeth of the comb plates Hi and II. The plate portion l8 is adapted to extend beneath the bottom face of the stationary comb II. Thespacer comb I8 is so constructed that it will hold the hair clipper at different distances from ones scalp depending upon the extent to which it is extended and so control the tapering of ones hair.

The shaft 2| is formed from two sections. There is a section 2| and a section 2!". These sections are in end alignment with each other and have their adjacent ends formed with overlapping parts (see Fig. 9). secured together with a pin 25. This pin 25 also secures a radially extending clip element 23 upon the shaft 2 I A spring 21 connects with the outer end of this clip element and extends rearwards through the hollow of the cover plate l2 and connects with a stationary pin 28. The arrangement is such that the spring 21 acts to normally hold the shaft 2| in a turned position, in which position the gear segments 22 hold the spacer comb fully retracted. The handle 23 may be depressed, turned clockwise in relation to the showing in Fig. 1, to correspondingly turn the gear segments and so extend the spacer comb.

At the ends, each of the gear segments 22 are provided with projecting finger portions 22 whichare adapted to strike against the free ends of the racks l9 and eject the racks from the slots 20 when the gear segments 22 are turned to their fullest extent clockwise. Thus it is possible to easily remove the spacer comb. This is done merely by pressing the handle 23 downwards to its fullest extent. To re-engage the spacer comb in position the handle 23 must be pressed down to its fullest extent and then the spacer comb shoved upwards until the free ends of the racks i 9 strike the fingers 22 Then as the handle 23 is permitted to move upwards the gear segments 22 will draw in the racks l9, and so move inwards the spacer comb.

A means is provided for limiting the position to which the handle 23 may move anti-clockwise and so control the amount to which ones hair may be clipped. This means comprises a lug 3!! projecting from the side of the cover plate l2 and supporting an adjustment screw 3! which is threadedly engaged therein. This adjustment screw is adapted to have its lower end strike the handle 23 and form a stop for the handle. It is possible to turn the screw 3| to cause it to move upwards and downwards and so change the adjustment.

In Figs. 10 and 11 a modified form of the invention has been disclosed which distinguishes from the prior form in the construction and operation of the spacer comb. According to this form of the invention a lever 33 is pivotally attached by a pintle 34 upon each end of the stationary comb I I The top end of each lever 33 is provided with a pivotally supported arm 34 which extends forwards and engages into a socket 35 formed upon the top of the spacer comb 38. The lower end of each lever 36 may be manually depressed for controlling its pivoting and so the extension of the spacer comb 38. Each end of the lever 33 extends downwards and is adapted to be rested against ones hair and scalp so that by changing the inclination of the clipper relative to ones head it is possible to cause the lever 33 to pivot and so automatically control the spacer comb 33 without the necessity of any direct control thereof.

These parts are A direct control is provided for the spacer comb 38, and comprises a link 39 pivotally connected with one of the levers 33, and in turn pivotally connecting with a handle 40. This handle 40 is pivotally supported by a pin 4| to the stationary comb H. A spring 42 is connected with one of the levers 33 to normally urge the lever into a position in which the spacer comb 38 is retracted. The arrangement is such that the handle 40 may be manually pressed forwards with ones finger to pivot one of the levers 33, and so control the extension of the spacer comb. In Fig. 12 a still further embodiment of the invention has been disclosed in which a link 44 is pivotally mounted by a pin 45 on each side of the cover plate l2. On the extended end of each link 44 there is a holding arm 46. These holding arms are adapted to engage in socket portions 4'! formed on the top portions of the spacer comb 48. The connection between the holding arms and the sockets 41 is frictional. The arrangement is such that the spacer comb 48 may be manually pulled off from the holding arms 43. Then the holding arms and links 44 may be pivoted to the inoperative positons indicated by the dot and dash lines designated 44 and 46.

It is required that an operator place his finger against the side of at least one of the holding arms 46 and manually control the extension and retraction of the spacer comb 48.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I l I claim as new, and desire to secure by United States Letters Patent is:
