HAIR CUTTING MACHINE Filed March 31, 195@ 2 ShQets-Sheet 2 l Patented July 26, 1932 GEORGE N. HENDERSON, OF PHILADELPHIA, PENNSYLVANIA 'HAIRv CUTTING MACHINE Appliicationpled March 31, 1930.` Serial 440,537.

' My invention relates to hair clipping mechanism, and one object of my invention is to provide a suitable form of apparatus capable of being readily operated by the person whose hair is to be cut whereby such operation may be accurately and becomingly performed without cat-stepping or uneven cutting and in such manner as to give a properly shingled effect.

A further obj ect of my invention is to provide a. device which includes a portable frame directly and freely applicable to the head and adapted to support and guide clipping means which may be operated manually` or by power, electric power or the like, transmitted by a flexible shaft.

And a still further object of my invention is to provide tension means for holding the hair down at a point beyond the application of the cutting device to insure a proper cutting operation.

These and other features of my invention are more fully described hereinafter; reference being had to the accompanying' drawings, in which Figure 1 is a perspective view illustrating the application of my improved hair-cutting device in the position of use when employed for cutting the hair at the back of the head. v

Figure 2 is a plan view of the form of haircutting device illustrated in Figure 1.

Figure 3 is a side elevation of the same.

Figure 4 is a detached View of one of the` side plates of the structure shown in Figs. 1, 2 and 3, on a smaller scale.

Figure 5 is a plan view of another form of hair cutting device within the scope of my invention, with manually actuated clipping or cutting means.

Figure 6 isa sectional elevation on the line VI-VI, FigureA 5, and

Figure 7 is a detached view of one of the side plates of the structure illustrated in Figures 5 and 6.

Referring to the drawings, Fig. l illustrates the actual position of my hair-cutting device on the human head. The cutting means and the supporting frame therefor occupy the position shown and at the commencement oi' the cutting operation, the clipping means starts with very slight clearance so as to cut the hair veryclosely to and almost shave the neck at or adjacent to the lower margin of the hair. The clipping means is moved upwardly and outwardly or away from the head along guiding means carried by the frame until the full length and/or depth of cut has been accomplished; producingan accurate and uniform shingled eect.

My device comprises a frame made up of sideplates 1, l, in parallel relation, and these plates are connected in spaced position by cross-bars 2, which may be disposed at each endof the same. Each side plate is provided with a cam groove 3 whereby a cutting element or clipper may be guided as it is moved along the side plates of the frame; supporting guiding members 4l mounted in ball-bearings being carried by the cutting element or clipper so as to render the cutting device capable of ready movement when it is advanced or otherwise moved with respect u to the frame. The cutting element or clipper may be of any usual character includ ing a support or carrier 5 having a plurality of elongated teeth 6 which perform the function of a combpand serve to align the hair in proper position for engagement by and the actionlof the clipping means which may include blades 7 moved laterally, by suitable mechanism located within the carrier v5, with' respect to the teeth 6, with which walls 1 of the latter. I At the upper or for- 95 ward end of the main frame, I provide an adjustable tension lever 10 of yoke shape, pivotally mounted at 108L on the side vplat-es 1, and secured thereto in such'manner and 4under such tension as will permit it (to remain in adjusted positions as the cutting operation proceeds. r1`he function of this member is to hold down the hair just beyond the end of the main frame while the latter is held in a substantially fixed position against the head` and while the carrier for theV cutting element is being advanced along the cam grooves 3 in' the Yside walls of said frame.

ln Figs. 5, 6 and 7 I have shown a modified form of my improved hair-cutting device in,

which the cutting element is arranged to be manually operated. In this arrangement, a fixed rack 11, which may be disposed on one of the side plates llof the'main frame, serves to actuatea gear Wheel 12 carrying a cam member 13. The gear wheel is supported in a slidable carrier 1e, the forward end of which is provided with the cutting or Clipping means, which may comprise the Vteeth (5 constituting the comb which is passed through the hair in advance of the cutting effected by the cooperative action of the blades 7' which are moved laterallywith respect to the teeth CW; such blades 7 being carried by a plate 1G, having an arm 17 mounted for rocking movement upon a post 1S; the opposite end of said arm having a boss or projection 17a engaged by the cam member 13 operatively fixed with respect to the gear wheel 12.

T he gear wheel12 meshes with the rack 11 carried by the side wall 1 of the main supporting frame and by reason of such engagement motion will be imparted to the cam member when the clipper support carrying such gear is moved with respect to the main frame. The cam member effects movement of the blade members 7 with respect to the teeth 6a of the comb in one direction, while a torsion spring 18 carried by the post 18 effects movement of said blade memb-ers'in the opposite direction.

ln lieu of employing a gear Wheel arranged to mesh with a rack carried by a side Wall of the main frame which supports the cutting element, I may provide a friction .Wheel arranged to engage a side wall of the main frame; such friction wheel to be provided with a cam member similar to that illustrated in Figs. 5 and 6, and serving to actuate the cutting means in the same or substantially the same manner.

rlhe frame or carrierla supporting the cutting elementin the structure illustrated in Figs. 5 and 6 is guided in its action by rails 2O mounted en the inner face ofthe side plates 1:l of the main frame; brackets 21 adapted thereto being mounted on such carrier 14, and such brackets may have rollers 22 which ride on the top ofthe rails 20, while a bar or other member connecting such brackets to the carrier for the cutting element may have projecting portions 23Aunderlying said rails 20, f i

I claim:

1. In hair-cutting apparatus, the combination of a frame consisting of a pair of side plates having curved edges to substantially fit the head, cross-bars connecting and holding said plates; in spaced relationship; said frame being freely portable and adapted to be held in fixed position against the head, guiding means disposed on the inner faces of said side plates, a cutting device movable with respect to said sideA plates, supporting members carried by said cutting device and engaging the guiding means, means for operatingrsaid cutting device, and a member pivotally connected to said side plates and movable to `a position in front of the frame for holding down the hair in advance of the cutting Y operation.

2. In hair-cutting apparatus, the combination of a frame consisting of a pair of side plates disposed in parallel relation and spaced position, cross-bars connecting said side plates; said side plates being concavely curved on their under edges to conform substantially to the contour ofthe head and each of said plates having a cam groove on its inner face, la cutting device movable with respect te said frame, side supporting niembers carried by said cutting device and engaging said cam grooves, means for effecting movement of the cutting device with respect to v the frame held against the head, and a yoke-shaped member pivotally connected to said side plates and movable to a position in front of the frame for holding down the hair in advance of the cutting operation; said member having frictional engagement with the side plates of the frame whereby it may be heldin adjusted positions. Y f 3. In hair-cutting apparatus, the combination of a freelyportable frame made up of a pair of side plates disposed in parallel relation, crossbars connecting the ends of said lates inv spaced relation; said frame being adapted to be held against the head, a cutting apparatus mounted-for movement between the side plates of said frame lengthwise of the same, curved trachways for said movable cutting apparatus, roller members for supporting the cutting apparatusV in said trackways, means for operating the cutting device, and means foreffecting movementof the cutting device with respect to the frame held against the head, and a yoke-shaped member pivotally connected to said side plates'and movable to a position in front of the frame for holding down the hair inv advance of a cutting operation.
