SAMUEL SEVEESON', 0F VALDERS, WISCONSIN.

HAIR-CUTTING APPLIANCE.

Application filed July 23, 1923. Serial No. 653,253.

To aZZ whom it may concern:

Be it known that I, SAMUEL SEvEnsoN, a citizen of the United States, and resident of 'Valders, in the county of Manitowoc and State of Wisconsin, have invented new and useful Improvements in Hair-Cutting Appliances, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to certain new and useful improvements in hair cutting appliances of that type employing mechanically operated cutters, and has for one of its objects to provide a hair cutting appliance so designed and constructed as to facilitate the trimming of the hair at any desired length.

It is another object or this invention to provide an appliance of the character described employing suction or vacuum means in connection with the cutting element, whereby the hair over which the appliance is passed is drawn in between the teeth of the cutting element to thus facilitate the operation of the machine.

This invention has for another object to provide a hair cutting appliance in which the handle is shaped to most conveniently fit the hand and in which a drive connection between the drive or rocking arm and the movement of the cutting blade is such as to permit the positioning of the cutting blade at the desired angle with respect to the handle.

A further object of this invention resides in the provision of a hood or guard shield ing the cutting element to cause the suction or vacuum at the cutting members to properly draw the hair therebetween.

Another object of this invention resides in the provision of a cutting guard or hood for an appliance of the character described which is yieldably adjustable and functions as a gauge to assist in the cutting of the hair and is equipped with a transparent portion through which the cutting blades may be viewed at all times.

And a still further objectof this invention resides in the provision of a cutting appliance of the character described in which the handle proper is provided with a rounded portion or projection adjacent the cutting blade to provide a purchase on which the appliance is rocked or moved to effect a tapering cutof the hair and to steady the cutter in the hands of the operator.

With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims. In the accompanying drawings, 1 have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a side view in elevation of a hair cutting appliance embodying my invention;

Figure 2 is a view thereof, partly in longitudinal transverse section and partly in top plan, taken through Figure 3 on the plane of line 22, and

Figure 3 is a view similar to Figure 2 taken at right angles thereto on the plane of line 33 of Figure 2.

In my co-pending applications filed July 8, 1921, Serial No. 483,215 and February 1, 1922, Serial No. 533,435, are illustrated two forms of my invention in which a shield or guard is longitudinally slidably telescoped over the appliance proper and yieldably urged thereover. This invention, as illustrated in the accompanying drawing, eliminates the telescopic feature and comprises a handle member 5 which is preferably of tubular form having a hand grip portion 6 and a cutter carrying end 7.

The under-side of the hand grip portion 6 is preferably provided with a removable plate or cover 8 to permit access to the interior thereof for the purpose of assembling or repairing the driving means, to be later described. Connected with the rear of the interior suction chamber or compartment 9 of the handle is a flexible tube 10 which leads to a suction or vacuum creating means, not shown, and the other end of the compartment or chamber 9 is open adjacent the cutting elements, to be later described.

The under-face of the handle member 5, adjacent its end 7, is provided with a rounded or curved projection 11 from which the extreme end of the handle portion is inclined upwardly to which a fixed cutting blade 12 is removably secured by suitable means 13.

The cutting blade 12 is formed with a plurality of teeth 14 on its outer edge which preferably traverse the mouth 15 of the vacuumchamber 9, for the reasons to be hereinafter described. Cooperating with the fixed blade, is a movable cutting blade 16 having cutting teeth 17 cooperating with the teeth 14 of the fixed cutting blade in the usual manner. The movable cutting blade is held in proper alignment with the fixed cutting blade by a rib or guide 18 on the upper face of the fixed blade riding in a groove or channel 19 in the under-surface of the movable cutting blade.

The movable cutting blade is reciprocated at the desired speed by means of a rocking arm or drive member 20 medially pivotally mounted in the interior of the handle by a pivot pin 21 threaded in a lug 22. One end of the drive member is inclined at an angle substantially equal to the angle of the cutting blades and has a plurality of gear teeth '23 formed thereon which mesh with gear teeth 24 formed on the upper surface of the movable blade. The rear or other end of the drive member is provided with an enlargement 25 having a vertical guide slot 26 therein in which a bearing or roller member 27 journaled on a crank pin 29 of a wheel 30 is mounted, the wheel member being carried by a drive shaft 31 connected with a source of power, such as an electrical motor or the like, not shown, by a flexible cable or other means 32.

The cutting blades are yieldingly held in snug but sliding enga ement, to prevent hair from catchin there etween, by a spring member 33 w ich is maintained under tension by an extension or rojection 34 extended from the end of t e drive member carrying gear teeth 23. This structure is illustrated in my co-pending applications above referred to.

The shaft 31 is preferably jou'rnaled, ad- 'acent wheel 30 within a bearin 35 mounted in a web 36 formed in the hen le.

Enclosing the cutter end of the appliance is a'hood guard or shield 37 of ap roximately V-shape in side view and shape in transverse section with the apexes thereof pivotall secured to the handle member ad.- yacent e projectlon 11 by a suitable pivotmg means 38 whereby the hood has a movement over the cutting members as illustrated by the dotted and full lines in Figure 1.

One side wall of the hood member is preferably bulged or struck out to rovide an enclosing pocket 39 in which 1s mounted a spring 40 which is medially coiled, as at 41,

incense its other end 43 'made fast to the handle.

member by being inserted in an aperture 44 therein Spring 40 at all times exerts a force to yieldably urge the hood to its full line position illustrated in Figures 1 and 3, which position is governed by the transverse portion 45 of the hood which is preferably flattened out and abuts the upper and outer end of the portion 7. As best shown in Figures 2 and 3, a transparent portion 46 extends between the side walls of the hood member from the upper edge of the transverse part 45 and is grooved or arched so that movement of the hood on its pivots will maintain the transparent portion close to the extreme upper outer end of the handle member part The operation of my device is substantially as follows:

Grasping the handle 6, the operator starts at a pomt where the hair is to be cut short, employing the rounded rojection portion 11 as a purchase and bringing the cuttin blade 12 as close to the head as it is desired to cut the hair, the hood being moved back on its pivot against the action of spring 41 to provide a cover or guard whereby the suction draws the hair in between the teeth of the cutting blades, as will be readily obvious. The appliance is then moved over the head, the operator pivoting the instrument on the portion 11 to regulate the length of the cut, as will be obvious. drawn through the suction chamber and out through the tube 10 to a bag or suitable place of storage, not shown, and, if desired, the drive connection of the member 20 may be enclosed by a suitable partition 47 to prevent the cut hair from becoming entangled therein.

When it is desired to increase the length of the cut, the operator merely depresses the outer portion of handle 6 rocking on the point 11 as will be readily obvious, the shield following such movement. With the trans arent part 46, the operator is permitted a view of the cutting blades at all times and thus the operation of the appliance is materiall facilitated.

What I c aim as my invention is:

1. In an appliance of the class described a handle member, cutting means carried thereby, means for creating a suction at the cutting means whereby the hair to be out is drawn into engagement therewith, and a guard carried by the handle member pro-- viding means for causing the maximum force of the suction to be exerted on the hair over which the cutting means is moved.
