HAIR CLIPPER.

Application filed Jaiiuar'y 23, 1922. Serial No. 531,222. 7

, To all whom it may concern:

Be it known that I, WALT W. ADAMS, a citizen of the United States, residing at Rochester, in the county of Olmsted and State of Minnesota, have invented a new and useful Hair Clipper, of which the following is a specification.

This invention aims to provide an exceedingly compact hair clipper, the motor which drives the cutting element being housed in the handle of the clipper.

The invention aims to provide novel means for mounting and actuating the clipper, to provide novel means for controlling the operation of the motor which drives the cutter and, generally, to improve and to en- -hance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understoodthat, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made Without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in top plan, a device constructed in accordance with the invention, parts being removed and parts appearing in section; Figure 2 is a top plan wherein the cap portion of the handle has been removed, parts being broken away; Figure 3 is a bottom plan of the cap; Fig ure 1 is a section on the line 414 of Figure 2; Figure 5 is a fragmental longitudinal section onthe line 55 of Figure 1; Figure 6 is a fragmental transverse section on the line 6-6 of Figure 1.

In carrying out the invention, there is provided a support or handle 1, suitably shaped, as indicated in the drawings so.that it may fit in the hand of the operator, the member 1 comprising a base 2 provided at its forward end with a foot 3, there being an opening 1 in the forward end of the base 2, adjacent to the foot 3.v A toothed guard 5 is disposed below the foot 3, a spacer 6 being interposed between the guard and the foot, the guard and the spacer being-secured to the foot in any desired way. An upstanding securing element 7 passes through the foot 3 and through the spacer 6, the foot having an opening 8 for the reception of the securing element, as indicated in Figure 1. If desired, a recess 9 may be formed in the guard 5 for the reception of the head of the securing element. A cutter plate 10 is supported on the guard 5 for reciprocationin a direction transversely of the handle 1, the cutter plate being guided upon lugs 11, which, being formed on the guide 5, are received in elongated slots 12 in the cutter plate. There is an opening 14 in the rear edge of the cutter plate 10. A cover 15 is supported on the foot 3 and on the guard 5, the cover being supplied at its forward end with a slot 16 for the reception of the cutter plate 10, the securing element 7 passing through the cover, and a nut 17 being threaded on the securing element, to retain the cover inplace.

The numeral 18 marks the frame of an electrical motor, disposed within the base 2 and supported on the shoulders 19 formed in the base. Generally stated, the electrical motor may be of any desired form, and may be wired up as desired. The shoulders 19 have openings 20 adapted to receive securing elements 21, which, engaging the frame 18 of the motor hold the motor in place in the base 2. A bracket 22 is connected to one side of the frame 18 of the motor by securing

devices

23 and 2 1. The base 2 has a bearing 25 wherein the shaft 26 of the motor is received for rotation, the armature of the motor being denoted by the numeral 27 and the commutator being marked by the reference numeral 28. The field winding of the motor appears at 29. In one end of the base 2 there is an opening 68 adapted to receive a flexible sleeve 30 surrounded by the usual reinforcing spring 31, a cable 32 extending through the sleeve, the cable comprising-

conductors

33 and 34. The conductor 33 leads to one end of the field winding 29 of the motor,

the other end of the field winding of the motor being connected to a spring contact tongue 35 carried by and suitably insulated from the frame 18 of the motor, the adjacent terminal of the field winding of the motor being housed beneath an insulating strip 36 extended beneath the bracket 22 and held by the securing element 23.

The numeral 37 marks an inner binding plate, the numeral 38 denoting an outer binding plate. A switch tongue 39 and a switch tongue 40 are located between the

binding plates

37 and 38, an insulating plate 41 being disposed between the switch tongue 39 and the binding plate 37 as shown in Figure 6. An insulating plate 42 is located between the switch tongue 39 and the switch tongue 40, in contact with the switch tongue 40 but spaced from the switch tongue 39. An insulathig plate 43 is dis-- posed between the switch tongue 40 and the binding plate 38, in ontact with the binding plate, and spaced from the switch tongue 40. A securing element 44 connects the binding plate 37, the binding plate 38, the switch tongue 39, the switch tongue 40, the insulating plate 41, the insulating plate 42 and the insulating plate 43, mechanically, with one side of the base 2 adjacent to the forward end of the base. The conductor 34 extends between the insulating plate 43 and the switch tongue 40, and is in contact with the switch tongue 40. An angular spring contact member 45 is provided, one end of the contact member extending be tween the insulating plate 42 and the switch tongue 39, in contact with the switch tongue. A binding element 46 extends through the plate 37, the plate 38, and parts therebetween, and serves to hold the end of the conductor 34, and one end of the contact member 45 in place, as will be understood readily when Figures 6 and 2 are compared. The base 2 is provided upon one side with a boss 47 wherein a button 48 is mounted for reciprocation, the button being carried by a plunger 49, the inner end of the plunger being connected to the spring tongue 39, the construction being such that when the plunger is thrust inwardly, through the instrumentality of the button, the spring tongue 39 may be brought into contact with the tongue 40, thereby to close the circuit of the motor to energize the motor.

The handle 1 comprises a cap 50 mounted on the base 2 the cap and the base having cooperatin openings 51, adapted to receive securing efements whereby the cap is held on the base. An insulating plate 52 is secured to the under surface of the cap 50 and has an opening 57 adapted for the receptlon of one end of the motor shaft 26. Insulating pieces 53 are secured at 54 to the cap 50 and rest on the plate 52, the members 53 carrying

resilientbrushes

55 and 56, adapted to cooperate with the commutator 28, the butt of the brush 56 being engaged by the spring contact member 45, and the butt of the brush 55 being engaged by the spring contact tongue 35. Clearly, when the button 48 i-sthrust inwardly, the circuit of the motor will be closed, thereby to energlze the motor and-to secure a rotation of the shaft 26.

A lever 58 is located within the base 2 and extends longitudinally thereof, the lever belng fulcrumed at one end upon the base, as shown at 59. At its forward end the lever the handle.

carries a U-shaped arm 60 adapted to extend around the securing element 7, the lever projecting through the opening 4 in the forward end-of the base 2. The arm 60 of the lever 58 is provided with a finger 61 received in the opening 14 of the cutter plate 10. The lever 58 is provided with an aperture 62 receiving the bearing 25 and permitting the lever to swing with respect to the bearing. The lever 58 is equipped with an opening 63 wherein operates an eccentric 64 carried by a gear wheel 65, the eccentric and the gear wheel being journaled on a shaft 66 mounted in the base 2, the gear wheel meshing with a pinion 67 secured to the motor shaft 26.

It will be obvious that when the motor is in operation, the pinion 67 will rotate the gear wheel 65, rotation being imparted to the eccentric 64, the eccentric transmitting motion to the lever 58 and causing the lever to swing on its fulcrum 59. When the lever is swung as aforesaid, the finger 61 on the arm 60 of the lever, cooperating with the cutter plate 10, will impart reciprocation to the cutter plate, the cutter plate sliding on the lugs 11 and coacting with the toothed guard 5 to shear 0d the hair.

' The device is so constructed that it is compact in form, all working parts, including the prime mover, being located in or upon the handle 1.

The device forming the subject matter of this application is adapted to be used in connection with a rheostat, a rectifier, or any other common and well known instrumentality of a like sort, but since these details form no part of the present application, the drawings have not been encumbered by a showing of them.

Briefly considered, the hair clipper forming the subject matter of this application comprises a handle 1 having a flat internal surface S and equipped at one end with a guard 5, a bearing 25 projecting from the flat surface of the handle,'a bracket 22 being carried by the handle and overhanging the flat surface of handle. A first shaft 26 is carried by the bearing 25 and by the bracket 22, a second shaft 66 being carried by the bandle and projecting from the flat surface S of There is an eccentric 64 on the second shaft 66. A cutter 10 is mounted to reciprocate with respect to the guard 5. A lever 58 is engaged at one end with the cutter 10 and is fulcrumed at its opposite end, as at 59, on the handle, the lever being slidable on the flat surface of the handle. The lever 58 is providech intermediate its ends, with

openings

63 and 62 in one of which, namely the opening 63, the eccentric 64 operates to oscillate the lever, the other opening '62 receiving-the bearing 25 and being of sufficient size to permit the lever to oscillate with respect to the bearing. The shafts 26 and 66 are, respectively, intermeshing gear mem- 58 that they serve to hold the lever for oscillation on the said flat surface S.

Having thus described the invention, what is claimed is: A

A hair clipper comprising a handle having a flatv internal surface and equipped at one end with a guard, a bearing projecting from the flat surface of the handle, a bracket carried by the handle and overhanging the flat surface of the handle, a first shaft carried by the bearing and by the bracket, a second shaft carried by the handle and projecting from the flat surface of the handle, an eccentric on the second shaft, a cutter mounted to reciprocate with respect to the guard, a lever engaged at one end with the cutter and fulcrumed at its opposite end on the handle, the lever being slidable on the flat surface of the handle, the lever being provided, intermediate its ends, with openings, in one of which the eccentric operates to oscillate the lever, the other opening receiving the bearing and being of suflicient size to permit the lever tooscillate with respect to the bearing, and intermeshing gear members on the shafts, the gear members being disposed parallel to the flat surface of the handle and being located so closely to the lever as to hold the lever for oscillation on the said flat surface of the handle- In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.
