. ing and has for its primary object to produce a device which is simple in construction, emcient in operation, and inexpensive tomanufacture.

Plucking of the eyebrows at present is performed by manually operated tweezers and results in considerable pain and inconvenience to the patient or recipient due to the fact that each hair is individually plucked and the extraction is relatively slow. It is therefore a further object of the invention to produce a device of the type referred to which is automatic in its operation and wherein the hair is extracted with such speed that the pain is negligible and the result much more quickly and eciently obtained.

Another object of the invention is to produce a device of the type referred to which is power driven.

Ano-ther object oi the invention is to produce a continuously operated hair pulling device.

With the objects above indicated and other objects hereinafter explained in view, the invention consists in the construction and combination of elements hereinafter described and claimed.

In the drawing, II indicates a hair removing device embodying the present invention, and comprises an elongated tubular housing I2 formed of any suitable material. llhe device is prefer- (Cl. 12S-355) ably constructed in such a manner as to readily t within the hand of an operator. One end of the tubular member i2 is closed by means of a plate I3 which has a lateral flange I4 extending circumferentially upon the inner side thereof and formed integral therewith, the -diameter being such as to permit the insertion of the ilange within the open end of the tubular member I2, as clearly shown in Fig. 4. The plate I3 is detachably secured to the end of the tubular member l0 the pins projecting beyond the outer surface of the member for a purpose to be later described. l5

The opposite end of the tubularmember I2 is exteriorly screw-threaded and receives thereon an interiorly screw-threaded cap It which normally closes the end of the tubular member and is provided with an axial opening I'I. This cap is for the purpose of permitting access to the working parts of the hair removing device, as will be later more fully described.

A member I8 is slidably mounted within the tubular member l2 and has secured to its for-- Ward end a pair of fingers or tweezers i9 and 2i) respectively. The finger I9 is rigidly secured to the upper portion of the member I8 and extends through an opening 2I provided in the upper portion of the plate I3 and for a suitable distance therebeyond. The ringer 2B is mounted for relative movement with respect to the nger i9 by means ol a pivo-t pin 22 carried by the member I8 and similarly extends through an opening 23 in the lower portion of the plate I3 and a 25 formed integral with the inner side of the plate I3 or otherwise secured thereto which serves to guide the fingers iS and 20 in their reciprocating movements. The finger 29 has a portion 26 extending rearwardly from the pivot 22 which is provided with bifurcated ends 2l spaced apart as shown in Fig. 4. These ends 21 have slots 28 extending angularly and inwardly from the upper ends thereof and are adapted to receive therein the free ends of a transversely extending pin 29 carried by one end of a link 30. The co- Cil operation of the pin 29 with the slots 28 is such that, upon longitudinal movement of the link 30, the finger 28 is moved about its pivot 22, with the result that the finger 29 is moved toward and away from the nger I9, depending upon the direction of movement of the link 3U.

The member I8 has extensions 3| projecting laterally from opposite sides thereof to a point adjacent the inner surface of the tubular member I2. These extensions have axial bores 32 which receive coil springs 33 at the bottoms of the bores and friction members 34 disposed within the bores between the coil springs 33 and contacting with the inner surface of the member I2. The springs 33 should be of sufficient strength to produce the necessary frictional resistance between the friction members 34 and the adjacent wall of the tubular member .I2so that relative movement of the fingers I9 and 20 is effected before any longitudinal movement of the fingers occurs. This construction permits the fingers I9 and 28 to be moved into hair gripping position, and then while so engaged, to cause the fingers to be moved longitudinally, thus pulling the hair. The resistance of the springs 33 determines the pressure of the cooperating fingers upon the hair which is to be pulled, so that various degrees of pressure may be obtained by substituting springs of various tensions. When the fingers I9 and 20 have been moved to their maximum innermost position, as shown in Fig. 5, the member I8 is moved in the opposite direction, or forwardly of the tubular member I2, and, due to the frictional resistance afforded by the friction members 34, the fingers I9 and 20 are first moved relatively to discharge the hair which has been pulled. This movement is then followed by the forward movement of the member I 8 to its initial operating position. While a positive and variable resistance to the longitudinal reciprocation of the member I8 has been provided by the use of the friction members 34 to effect a closing of the fingers I9 and 20 about a hair prior to the pulling operation ,any other manner of offering a resistance to the longitudinal movements of the member I8 may be employed, such as, for instance, by providing sufficient weight in the member I 8, the inertia of which must be overcome before any longitudinal movement thereof is possible. This resistance should be sufficient to cause the fingers I9 and 26 to be moved to hair gripping position before any appreciable longitudinal movement of the member I8 takes place. The cycle of operations, therefore, includes moving the fingers I9 and 20 together to grip the hair, moving the fingers rearwardly while in gripped position to pull the hair, separating the fingers I9 and 20 to discharge the hair, and moving the fingers forwardly to their initial position.

To effect such movement of the fingers I9 and 20, a member 35 is secured within the member I2 by means of a pin 36 which passes through aligned openings in the member 35 and the adjacent walls of the tubular member I2, thus preventing movement of the member. The member 35 has forwardly extending ears 31 formed integral therewith and spaced apart as shown in Fig. 3 and between which the extension 38 is disposed. The ears 31 ,and extension 38 are provided with aligned openings to receive a pin 39 about which the extension 38 pivots. The extension 38 has laterally extending portionsv 40, one of which is pivotally connected at 4I with the bifurcated end of the link 39. The member 35 has a pair of longitudinally extending bores 42, one

positioned above the pin 36 and the other positioned below the pin 36, as shown in Fig. 2, which .are adapted to slidably receive therein pins 43 which are of a greater length than the length of the member 35. The ends of these pins are so 5 positioned as to be in alignment with the opposite ends of the portions 40 and to be engageable therewith in alternate relation, functioning to alternately cause reciprocation 0f the member I8 in opposite directions. 10

A cam 44 is positioned within the member I2 and has an angularly extending surface 45 adapted to be engaged by the opposite ends of the pins 43. This cam has a hollow shaft 46 extending axially thereof and is rotatably jour- 15 naled in spaced bearings 41 mounted within the member I2. A flexible cable 48 has one of its ends secured to a member 49 which Vhas its free end extending within the tubular shaft 49 and is provided with a slot 50 engageable with .a key 5I 20 secured to the cam 44. An enclosure 52 for the cable and member 49 is provided and has a fiange 53 which fits within the cap I 6 and is held in rigid engagement with the adjacent end of the tubular member I2. The opposite end of the 25 flexible cable 48 is connected with .an armature of a motor 54 through a suitable gear reduction or directly, if desired, by which rotation is imparted to the cam 44 for alternately reciprocating the pins 43. A speed control 55 may be provided 30 upon the motor to obtain the desired speed and energy and the motor may be supplied with current from any suitable source through a cable 56 controlled by a button switch 51.

In Figs. 8, 9 and 10 a modification of the device 35 embodying the invention is disclosed but which operates precisely on the same principle, that is, the cycle of operations is the same but the manner of operating the device is somewhat different. In this construction, the members I9 and 28 are 0 maintained in their initial position by means of Y a coil spring 58 which surrounds a rod 59 slidably mounted within a member 60 secured at one end of the tubular member I2 by means of the cap It. One end of the coil spring abuts the adjacent 45 inner end of the member 60, while the opposite end of the spring abuts a collar 6I formed integral upon the opposite end of the pin. The pifi' 59 beyond the collar 6I is provided with an extension 62 within which is secured a transversely 50 extendingrpin 63 the free ends of which are disposed Within angularly extending slots 64 formed in the pivoted finger 20. The tension of this spring 58 tends to urge the slidable member I8 forwardly, and a flexible cable 65, which has one 55 of its ends secured to the member 59, -tends to move the movable member I8 in the opposite direction against the resistance of the spring 58. The opposite end of the cable 65, in this construction, is connected to the motor 54 through 50 the medium of an eccentric connected with the .armature of the motor so as to cause movement of the flexible cable 65 longitudinally.

The nger I9 is secured to the slidable member I8 by means of bolts 68 which are readily rernova-t 155 le by removing the pivot pin 61 of the pivoted finger 28. Furthermore, in this connection the member I8 is provided with a transversely extending bore 69 within which is secured a tubular member 19. Within the tubular member 10 is a ,70 single coil spring 1I, the opposite ends of which abut with the adjacent ends of friction members 12 which in turn engage the adjacent wall of the member I2.

In the operation of the device, the motor 54 is A7x5 star-ted, which causes either rotation of the flexible cable 48 or reciprocable movement of the flexible cable 65, depending upon which device is being employed. In the former, this causes the cam l to be rotated, which alternately reciprocates the pins (i3 and likewise causes alternate reciprocating movement of the portions i0 upon the extension 38. As one of the portions i0 is pivotally connected to the link 39, the member I8 is likewise reciprocated, and, due to the frictional resistance offered by the friction members 34, the first movement oi the link S53 causes the fingers i9 and 2B to be moved relatively into engagement with a hair which is to be pulled. Further movement of the link Si] causes the member It to be moved longitudinally within the member i2, thus moving with it the iingers I9 and 2t) which, still gripping the hair, tends to pull the same. At the end of this movement, the movement is reversed, with the result that with the first movement of the link 3i] the ngers It and ES are moved apart, releasing the hair, as the friction members 34 resist the movement oi the slidable member I8, and then further movement of the link 3G returns the fingere is and 2&3 to their initial position.

It has been found desirable to operate the iingers I9 and 2i) at approximately 1360 R. P. M. of the flexible cable, but of course different conditions may require that the cable be operated at different speeds.

As the cycle of operations is performed at such high speeds, it will be readily apparent that the hair is extracted so quickly that it is almost impossible to detect nany pain accompanying the saine, and where the operation of plucking eyebrows now consumes several hours time, this device makes it possible to erform the same job within a few minutes time.

A cap 'I3 is mounted upon the end of the device so as to enclose the fingers and prevent damage thereto in case of dropping or otherwise. This cap may be secured by bayonet slots and cooperating pins, as shown in Fig. 2, or by merely frictional engagement, as shown in Fig. 8.
