HAIR CUTTING MACHINE Filed April 22, 1939 INVgNTOR A9 (/asep/I .Juazz/ wymw mg I ATTORNEK? Patented Dec. 26, 1939 UNITED STATES ATENT OFFICE HAIR CUTTING MACHINE Joseph Suozzi, New York, N. Y. Application April 22, 1939, Serial No. 269,541 v 4 Claims, (01. -206) My'invention relates to a motor actuated device for cuttingthe human hair and particularly to that type of mechanism in which a series of cutting blades mounted on a rotating shaft bear successively against a stationary'blade to effect the cutting-a type sometimes referred to as the mower type.

I am aware that hair clipping mechanisms have been in use for many years in which there'is provided a member adjustable toward and from the clipper to regulate the length of the cut, and also that mechanisms are known wherein a rotary cutter contacts a stationary cutter, but the mechanisms now known and in use are useful only where the cuttingv is to be relatively uniform throughout as on the back of the neck and on the sides of the head, and are not emcient where the hair is to be of varying lengthsyand hence are not practical for giving a complete hair-cut.

An object of my invention is to provide a mechanism, with which a barber may, without the necessity of using scissors at all, give a customer a complete hair-cut in any desired style or of any desired length, and in much, less time than when the customary method is employed of cut- I ting the sides and back of the neck with clippers,

and then trimming the top of the head with scissors.

My invention will be best understood by reference to the accompanying drawing in which:

Fig. 1 is a view from the left showing one embodiment of my improved mechanism;

Fig. 2 is a view showing a modification of my invention; and

Fig. 3 is a View of the cutter and comb mechanism.

In the drawing the numeral i represents the outer casing. of an electric motor, which may be of any well-known type procurable at any electrical shop and which constitutes no part of the invention. From the back of the motor casing extend wires 2 which may beconnected to any suitable source of power (not shown), and switch 3. The numeral 4 designates a bail by which the mechanism may be hung on the wall when not in use, and 5 and 5b are hollow heads within which spring contacts may be inserted into the motor casing.

Secured to the forward end of the motor casing l is an insulating plate 6 to which is clamped a metal frame 1 having the forwardly extending parallel arms 8 and 8'.

At the forward end of the arms 8 and 8' and secured therein by

nuts

9, 9 mounted on the outer sides thereof is a shaft l0 rotatably mounted in bearings H, H. The bearings II, II carry a plurality of upwardly extending lugs l2, I2 to which are removably secured the mower knives [3, I3.

Attached to the nut 9 on the arm 8 is a gear It which meshes with the worm IE on the actuating shaft I6 which projects from the motor and which may be made either in a single piece or in two pieces connected by a universal joint, as desired. I prefer to employ a single straight shaft as shown in the drawing.

Removably secured to the arms. 8, 8' is a comb member ll provided on its outerend with teeth [8. This. member is preferably made of a single piece of metal, bent back upon itself to a U-shape in the recess of which is firmly but removably held the cutter blade l9. This blade is fashioned from a thin piece of sheet metal and at or near its cutting edge is bent upwardly in conformity with the contour of the comb member to ensure proper shearing contact with the mower blades [3.

The blade 19 at the end opposite its cutting edge is of such thickness that it will fit securely into the U-shaped recess in the comb member I], as shown in Fig. 3, and becomes gradually thinner towards the cutting edge. Once fitted in position within the U-recess, the blade will remain in place without the necessity of using any fastening means until it is desired to remove it for sharpening, cleaning or for some other reason. In the preferred form of my invention the points of the teeth l8 will be level with the upper edges of the arms 8 and 8', as shown in the drawing, but this is not necessary as the comb may be mounted at any advantageous point on the arms 8 and 8'.

The special means which I provide for regulating the length and style of hair-cut may comprise the slotted arms 20, 2t, embracing the arms 8 and 8, said arms being connected by cross bars 2i, 2! and being held in position on arms 8 and 8 by lugs 22, 22. The arms 20, 2t carry at their lower extremities rockers-23, 23 which may be of any convenient size and shape but are preferably as shown in the drawing. The position of the guide pieces with respect to the cutters, and thus the amount of'hair cut is regulated by the screw 24.

In the modification of my invention shown in Fig. 2, the slots 25 in the arms 20 would be provided with teeth 26 meshing with the gear 21 to raise or lower-the

rockers

23, 23, and the screw 24 will be at theback of the frame as shown and will be connected to the gears 27 by shaft 28 and worm 29.

It will be obvious that in operating the mechanism of my invention, as it is guided over the head manually, the hair is grasped between the rockers 23 and the comb member I1, and that the rockers are adjusted according to the length of cut desired. For example, where it is desired to crop the hair very closely, as at the back of the neck,'on the sides of the face and behind the ears, there will be a shorter distance between I the rockers and the comb than when the hair is to be left longer, as on the top of the head. The length and style of the cut may also be regulated by the position in which the mechanism is held, as it is obvious that it can be held in any desired position.

While one embodiment of the invention has been described in detail in order to illustrate the principles and advantages of the invention, it is to be understood that the invention may have various embodiments within the limits of the prior art and the scope of the subjoined claims.

I claim:

1. In a device of the class described, a motor within a casing, wires leading from one end of said casing and adapted to be connected to a source of power, a frame attached to the other end of said motor casing, said frame being open at its forward end, a rotary shaft mounted in the side arms of said frame at its open end, said shaft being journaled in bearings carrying upstanding lugs to which are removably secured a plurality of mower blades, a substantially U-shaped comb member removably secured to the open end of said frame, and carrying within the U-shaped recess therein a cutter blade adapted to contact with the mower blades, and rocker members positioned below said comb member and adjustable toward or away from said comb member to regulate the length and style of hair-cut.

2. In. a device of the class described, a motor mounted within a casing, lead wires extending from one end of said casing to a source of power, a frame secured to the other end of casing and open at its front end, a plurality of mower blades removably mounted on upstanding lugs on the bearings of a rotary shaft mounted in the side arms of said frame at its open end, a substantially U-shaped comb member mounted on saidframe at its open end and adapted to hold firmly but removably within its U-shaped recess a blade in contact with 3. In a device of the class described, a motor mounted within a casing, lead wires extending from one end of said casing to asource of power,

arms toward and away from said comb, and

means for holding said rocker arms against lateral movement.

4. In a device. of the class described, a motor mounted within a casing, lead wires extending from one .end of said casing to a source of power, a frame secured to the other end of the easing and open at its front end, a plurality of mower blades mounted on upstanding lugs on the bearings of a rotary shaft mounted in the side arms of said frame at its open end, a substan.- tially U-shaped comb member mounted on said frame at its open end and adapted to hold firm ly but removably within its U-shaped recess a blade in contact with said mower blades, a pair of slotted rocker arms embracing the side arms of said frame, a gear passing through the .slots in said arms and meshing with teeth out in the sides thereof, and a worm on the end of a screw shaft and meshing with said gear, allfor adjusting the rocker arms toward and away from the comb member.
