This invention relates to a hair cutting device driven by power, the general object of the invention being to provide a device which can be used for cutting the hair in the same manner that a barber uses scissors and a comb, it being understood that the device takes up the work of finishing the hair cut where the ordinary hair clipper leaves off.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is an end view of the device showing it turned up at right angles to the power unit.

Figure 2 is an elevation of the device removed from the power unit.

Figure 3 is a top plan view showing how the power unit can be connected with either notched part of the device.

Figure 4 is a view similar to Figure 1 but showing the device extending horizontally from the unit.

Figure 5 is a view similar to Figure 4 but showing how one spring arm of the power unit engages a pin extending into the notched part of the device.

Figure 6 is a fragmentary top plan view of the cutting bar.

Figure 7 is a section on the line 1'! of Fig ure 2.

Figure 8 is a section on the line 88 of Figure 3.

Figure 9 is a view of one of the spring arms in the power unit.

Figure 10 is a view of the member operated by the power unit and having its head engaging a notch in the cutter bar.

Figure 11 is a view of the central spacer bar.

In these drawings the numeral l indicates a comb which is made somewhat similar to the comb used by barbers in cutting the hair though the rear edge of the comb is provided with a pair of notches 2, one adjacent each end thereof and the comb is also provided with a slot 3 which extends from the rear edge of the comb to a point extending into the bases of the teeth. This slot is to receive a cutter bar 4, shown in Figure 6, this bar being made somewhat like a comb with its teeth 5 rounded on that face which is opposite the cutting face as shown at 6 and said teeth extend to that part ofthe slot which is located in the base parts of the teeth of the comb as shown in Figures 4, 5 and 7. As will be seen, the teeth of the comb and cutter bar are spaced a greaterdistance apart on one portion of each member than on the, other portion. The rear edge, of the bar 4 is formed with the notches 8 which are so ranged that they will be exposed by the notches 2 in the comb l and one face of therear portion 10 of the cutter bar is formed with a longitudinally extending groove 9 for receiving the ends of set.

lateral movement but will allow it to reciprocate. 15

Spacer bars I I fit in the rear portions of the slots 3 in rear of the cutter bar and have their outer edges projecting from the rear edge of the comb and these bars are held in place by the screws l2. The ends of the bars terminate at the notches and these ends are provided with the pintles l 3 which extend into the notches 2 and act as journals for the spring arms I41 that are attached one at each side of the power. unit A. Thus by pressing these two arms I4 toward each other they can be placed in the notch 2 and then permitted to spread apart so that the hole l4 therein will receive the pintles and this will rotatably connect the device to the power unit. By having the two notches the power unit can be connected to the pintles of either notch to permit the device to be used right hand or left hand as shown in dotted and full lines in Figure 3.

The power unit can be of any suitable type such as a common vibrator hair clipper and I provide an angle shaped member I5 having a rounded head I6 at one end thereof, the head engaginga notch 8 in the cutter bar. This member I5 is attached to the vibrator part I! of the unit as shown in Figure 3.

From the foregoing it will be seen that when the device is attached to the power unit the cutter bar will be reciprocated sothat the device will cut the hair practically in the same manner as a barber cuts the hair when using shears and a comb. By having the device pivotally connected with the power unit it can be turned to various positions and this adjustment of the device will not interfere with its operation by the unit owing to the rounded head l6 engaging a notch 8.

The device can be moved in a ninety degree (90) arc, similar to the use of a common comb in hair finishing. That face of the cutting bar which is opposite the curved face 6 is, of course, the cutting face, and by holding the lowermost face of the comb, with the parts arranged as in Figure 8, against the head, the device will cut the hair substantially to a length which is equal to the thickness of the lower part of the comb or that part between the cutting bar and the lower face of the comb, as shown in Figure 8. When a longer cut is desired, the device can be reversed from the position shown in Figure 8,

and when this is done, the hair will be cut to a length substantially equal to the thickness of the cutting bar and the upper portion of the comb, as shown in Figure 8. By using the coarse part of the comb, where the teeth are wider than the finer part of the comb, the hair will be cut longer than when using the fine teeth, and by reversing the device for each set' of teeth, as above described, four different sizes of cuts can be made by the device. Two-other sizes of cuts can be obtained by moving the comb up the side of thehead with the teeth pointing directly to the head, one out being secured by the small teeth when manipulating the device in this manner, and the other size by the large teeth.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What is claimed is:-

1. A hair cutter comprising a comb having a longitudinally extending slot in its rear edge extending into the bases of the teeth of the comb, a toothed cutter bar slidably arranged in the slot and having a notch in its rear edge, a power unit carried by the comb engaging the groove, the rear part of the comb having a notch therein, pins extending into the notch, a power unit provided with spring arms having holes at their outer ends engaging the pins and a member reciprocated by the unit and having a rounded head for engaging a notch in the rear edge of the cutter bar.

3. A hair cutter of the class described comprising a comb having a slot extending longitudinally through its rear edge with the front part of the slot extending into the bases of the toothed comb, a toothed cutter bar slidably arranged in the slot, a groove in the cutter bar, projections carried by the comb engaging the groove, the rear part of the comb having a notch therein, pins extending into the notch, a power unit provided with spring arms having holes at their outer ends engaging the pins and a member reciprocated by the unit and having a rounded head for engaging a notch in the rear edge of the cutter bar, and said comb having a second notch therein and pins extending into the same whereby the power unit can be placed in either notch for permitting the device to be used right hand or left hand.

4. A hair cutter comprising an elongated comb having a longitudinally extending slot in its rear edge extendinginto the bases of the teeth of the comb, an elongated toothed cutter bar slidably arranged in the slot and having one face of its toothed part providing a cutting portion, a power unit, means for pivotally supporting the rear part of the comb from said power unit, and means for operating the cutter bar by said power unit.

5. A hair cutter comprising an elongated comb having a longitudinally extending slot in its rear edge extending into the bases of the teeth of the comb, an elongated toothed cutter bar slidably arranged in the slot and having one face of its toothed part providing a cutting portion, a 4

power unit, means for pivotally supporting the rear part of the comb from saidpower unit, means for operating the cutter bar by said power unit, said comb and cutter bar each having one portion of its toothed part formed with coarse 45 teeth and the other portion with fine teeth.
