3 Claims.

electric shavers of the Schick and other types,

in which the shaving is done without lather or 5 cream and with the .hair or whiskers dry. In 4 the operation of such electric: shavers or the like, the hair is usually or frequently finely comminuted or cut into such short, pieces as to make an almost impalpable powder. These shavers operate at very high speedsand in some types the severed portions are discharged at the sides .of the shaver but I have observed that when the shaver is in operation there is apt to be a considerable amount of flying hair, hair particles, 15 and perhaps portions of epidermis discharged from the. shaver and such particlesare sufficiently fine or light as to more or less float in the air. This is particularly noticeable when shav I ing before a magnifying mirror by means' of go which such flying particles may be observed. It is generally understood that the whiskers and skin are more or less constant carriers of germs andsuch flying particles or dust may get into the eyes or nostrils of the user and cause inconvenience, infections, or the like.

In order to avoid such results I have provided an improved shaver or attachment for shavers of these types whereby such particles are collected and prevented from flying so that they are not apt to affect or injure the shaver.

The objects of this invention are, asindicated, to collect the hair or other particles formed by dry shaving operations; to provide suction means for drawing the whiskers or the like from the cutter head and to convey the same away from the face; to provide a vacuum cleaning attachment for a dry mechanical shaver; and to provide such other advantages and improvementsas will appear from the following description.-

In the accompanying drawing illustrating this invention,

Figure 1 is a plan view of a shaver of the Schick type showing my improvement, parts being shown in section substantially on the line 1-4 of Fig. 2;

Figure 2 is a side view parts also broken away or shown in section for convenience in illustration:

Figure 3 is an enlarged detail showing the suction connnection with the cutter head;

Figure 4 is a detail of the air strainer or outlet; and

Figure 5 is a modification showing the means for coupling the fan to the motor shaft of a shaver as ordinarily constructed.

As shown in this drawing the shaver housing or casing 6 is of the commercial form and is provided with a cutter head 1 having the usual reciprocable cutter element 8 which is driven by a motor 9 through suitable driving mechanism (not shown) these parts being parts of the standard or commercial forms of such shavers. The cutter head has a passageway l0 therethrough into which the severed hairs pass as they are cut and such hairs are ordinarily discharged out one or 10 the other ends of the passageway, depending upon the position of the cutter head and as above stated are apt to fly in all directions incident to the cutting operation.

In order to collect and remove such flying particles of hair and the like, I provide a fan H which maybe mounted directly on the end of the motor shaft l2 if the attachment is made as a part of the new shaver. However, in order to supply the device as an attachment for completed shavers I may utilize a small coupling or connector l3 on the end of the fan shaft M 'as shown in Figure 5, which coupling has a small tip or projection l5 that engages with a hole IS in the end of the motor shaft l2 as ordinarily constructed in this type of shaver.

The fan may be of any suitable type such as a centrifugal fan as shown in which the housing I1 is made integrally with the cover or cap 18 forming a part of the shaver housing. This cover or cap portion is ordinarily secured to the body 6 by means of screws I9. An intake conduit 20 leads from the fan housing down to a point adjacent to one end of the cutter head I and has an intake orifice portion 2| which is shaped to conform to the end of the cutter head and so that it will not project'beyond the sides or front of the head or otherwise interfere with the cutting operation. In order to make a tight connection between the cutter head and the suc- 40 tion member 20 I may provide a gasket or yielding washer '22 which is fastened to the inlet as shown in Figure 3. The cutter head is detachable and when placed in operating position may be placed closely against such gasket. The outlet or discharge from the fan may be led away or directed to any convenient point for disposal of the comminuted whiskers but in the arrangement shown I provide a collecting chamber 23 which may also be made integrally with the cover l 8 and which has a, relatively wide discharge opening or outlet orifice 24 at the back of the shaver. This orifice is closed by a gate or closure comprising a frame portion 25 and a dust and air separator 26. The gate may be mounted in 86 any desired manner as by means of a hinge 21 and provided with a fastening clip 28 for holding it in closed position. 7

In the drawing the shaver is shown on an enlarged scale but it will be understood that the attachment or improvement is to be made as small as convenient and designed so that it will pro-- vide a, neat appearance and will not detract from the convenience and use of the shaver.

In the operation of my improved shaver the shaving implement is used in the ordinary manner and particles of hair or epidermis removed by the cutting apparatus will pass into the cutter head. The suction provided by the fan will ,draw air through the cutter head and through the fan inlet conduit 20 and discharge the same into the chamber 23. Any hair or the like will be carried along with the air and discharged in the chamber being separated from the air by the strainer or gauze 26 as the air passes from the, chamber. When suflicient hair or particles have been collected in the chamber the door 25 is opened and the accumulated particles cleaned from the chamber preparatory for further'use. In this manner the particles of whiskers or the like will .be prevented from getting into the eyes or nostrils of the use. and thus prevent irritation orinfection of thesame. This also prevents the whisker particles from being discharged from the cutter head onto the garments of the user or other undesirable points. It will also be noted that the discharge from the fan may be carried away from the shaver and the particles deposited I at a remote point if desired without separating the particles from the air.

While I have shown a conventional form of fan it will be noted that other types may be utilized if desired and changes may be made in the arrangement of parts or the generalconstruction in order to adapt the improvement to other shavers or clippers, without departing from the spirit of the invention as set forth in the'following claims, in which I claim: I

1. The combination with an electric shaver including a casing adapted to be held in the hand of the user and having a shaving head, and a motor for actuating the same mounted in said' casing, of a fan driven by the motor, a housing in the casing for said fanwhich is closed from the motor chamber, a conduit in the casing leading from the housing to a point adjacent to one end of the shaving head and opening into the same, a gasket between the end of the conduit and the shaving head, and a dust separator comprising a chamber in the casing connected with the outlet of the fan having a screened outlet and adapted to collect the particles discharged thereinto by I the fan.

2. The combination with an electric shaver of the Schick type, having a body portion and a cover portion, of a cover for replacing the cover portion, a fan housing in the cover, a fan mounted. in the housing and driven by the motor of the shaver, a passageway leading from the fan intake to a point adjacent to one end of the passageway in the shaver head and adapted to draw air through the shaver head, a dust separating chamber on the coverconnected with the fan exhaust andhaving an outlet opening and a screen movably mounted to cover the opening, said screen being adapted to beopened for removing the contents of the chamber.

3. The combination with an electric shaver of the Schick type, having a casing, of a fan of air from the chamber.
