1 Claim. (Cl. 30-219) This invention relates to a hair clipper.
The' object of the invention is to provide a hair clipper' which is provided with a vacuum means or mechanism so that as the hair is cut' by the cutting mechanism, the cut hairs will be sucked into a suitable receiver or chamber within' the device.
Another object of the invention is to provide a hair clipper which can be conveniently held in the hand, and wherein a motor means is provided in the hair clipper for simultaneously operating the cutting mechanism andv whrein the motor means also operates a suction cre ating fan so that as the hair is cut by the cutting mechanism, the hair will be sucked into a suitable compartment or chamber'within the clipper so as to insure that the hair can` be cut in a clean and sanitary and advantageous manner.
A stillfurther object is to provide a simple and inexpensive construction for performing the stated functions.
With these and other objects inview, this invention consists in certain novel features of construction, combinations and arrangement of parts to be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which:
Figure 1 is a longitudinal sectional View illustrating the combination hair clipper of the present invention.
Figure 2 is a sectional view taken on the line 2-2 of Figure 1. v
Figure 3 is a sectional view taken on the line 3--3 of Figure 2.
Figure 4 is a sectional View taken on the line 4-4 of Figure 2.
Figure 5 is a sectional view taken on the line 5-5 of Figure l.
Referring in detail to the drawings, the numeral indicates the hair clipper of the present invention which comprises a housing 11, Figure 1. A shaft 13 is driven by a motor 12, and the motor 12 is adapted to be arranged in an end of the housing 11. Mounted on the shaft 13 is a cam 14, and the shaft 13 also serves to operate or rotate a fan 15 so as to create the necessary suction.
The housing 11 is provided with a chamber 16 which is adapted to receive the cut hair, and a passageway 18 communicates with the chamber 16 so that the cut hair can be sucked in from the vicinity of the cutting mechanism 21, and this cut hair will them pass through the passageway 18 and be received in the chamber 16. A valve 19 is provided for controlling the flow of air through the passageway 18, and the valve 19 is controlled by means of an adjustable pin or screw member 20.
As shown in the drawings, the cutting mechanism 21 includes a stationary body member 22 which has a bar 23 secured thereto or formed integral therewith, and the bar 23 is received in a slot 24 of a support member ICS 29, the support member 29k being an integral part: ot the housing .11. A screw member` 25l extends through the support member 29 and engages the bar 23, as for example. as shown in Figure 1.
The cuttingv mechanism. 21 includes in addition. to thestationary bodyv member 22', a movable cutter memberY 26, Figure 3, and the body member 22 is provided withl teeth 27 which are adapted tov coact withk teeth 28.on` the movable cutter member 26.
Connected tothe support member 29 is a pivot pin 30 which has a bearing 31 rotatably mounted thereon, and an arm 32 extends rearwardly from the bearingl 31; and is secured thereto or formed integral therewith. The arm 32 hasa. U-shaped bracket 33' on itsl rear end,- and as shown in Figure 5 for example, the spaced apart portions of the bracket 33 are arranged in engagement. with the cam 14. The arm 32Y includes portions 34, 35, and 36- which are arranged angularly with respect to each other, and a4 suitable clearance. spiace, is provided. in the housing 11 for permitting the arm. 32 to move4 back and forth as the motor 12. isactuated. A manu-- allyoperable switch 371 is provided for` controlling actu.- ation of the motor I12, and the motor 12 may be connected to a suitable source of electrical energy by means` of the wires 38.
Extending from the bearing 31 and connected thereto is a finger 39, andthe finger 39 is providedv with aslot 40 therein, Figure 2. A link 41 is adjustably connected to the finger 39, and the link 41 includes an4 angularly arranged portion 42 which is connectedA to the movable` cutter member 26 by means of a securing element 43. A- securing element or screw member 4,4' extends through` the slot 40 and is connected to the link 41, and a coil spring 45 is interposed between the securing element 44 and the bearing 31, Figures 1 and 2.
The numeral 46 indicates a guard'or shield'which is connected to the cutting mechanism 21, and the guard 46 is held in place by means of securing elements 47 which securing elements 47 extend through slots 49 in the movable cutter member 26. The guard 46 is provided with a cutaway portion 48 that provides sufficient clearance for the end portion 42 of the link 41.
From the foregoing, it is apparent that there has been provided a hair clipper which is adapted to be used for conveniently cutting a persons hair and creating a vacuurn so that the cut hair will be sucked into a receiver such as the receiving chamber 16. According to the present invention, the housing is provided with a cover 50 which can be removed as for example when the chamber 16 is to be emptied of the cut hair.
In use, by turning on the switch 37, electrical current will cause the motor 12 to be actuated so as to rotate the shaft 13. As the shaft 13 rotates, it rotates the fan 15 so that a suction will be created whereby the hair which is cut by the cutting mechanism 21 will be sucked in through the passageway 18, and this hair will then be received in theY chamber 16. The screen 17 will prevent the hair from accidentally leaving thev chamber 16.
At the same time, as the shaft 13 rotates, it causes rotation of the eccentric or cam 14, and since the U- shaped bracket `33 on the end of the arm 32 is arranged in engagement with the cam 14, it will be seen that the arm 32 will be swung back and forth on the pivot pin 30. This movement of the arm 32 will cause back and forth rotation of the bearing 31 on the pin-30 which in turn will cause corresponding swinging movement of the linger 39 and link 41. Since the link 41 is secured to the movable cutter member 26 by means of the screw 43, it will be seen that the cutter member 26 will be reciprocated or moved back and forth with respect to the stationary part 22rof the cutting mechanism 21 so that the teeth 28' and 27 will coact to sever or cut the hair.
By adjusting the screw in or out, the position of the control valve 19 can be changed s0 as to regulate the amount of vacuum created in the passageway 18.
The parts can be made of any suitable material and in different shapes or sizes.
The guard 46 may be made of any suitable material such as spring steel, and the necessary tension will be kept on the clipper head blades, and the assembly will be properly held together. The chassis or housing can be mates and using batteries which can be inserted in the receiver that is used for the hair. It can also be converted or made into a portable combination hair clipper by exchanging motors only and placing the batteries in another container.
Thus, it will be seen that there has been provided an electrically powered hair clipper which is adapted to cut hair and pull the hair from the blades at the same time and thus a person can have the hair cut in a more cool and cleaner fashion or manner.
As stated previously, the electric motor 12 rotates the cam 14 which causes movement of the clipper blades, and the fan 15 is on the same shaft 13 that the cam 14 is on. The fan blades create a vacuum which draws the hair from the clipper blades into the receiver 16, and the receiver can be emptied after each haircut, or when full.
The clipper head 21 may be easily attached or removed, and the spring 45 keeps the clipper blades from chattering and keeps the necessary tension on the blades. The screw member 25 helps maintain the clipper head assembly attached to the housing. If desired, a cloth or paper liner can be used in the chamber or receiver 16. The fan blades may be of any suitable type to create the desired vacuum. The motor 12 may be of the reversible type for blowing the hair out of the receiver as for example when a liner is not used. The cover may be transparent to determine when the receiver is to be emptied.
Minor changes in shape, size and rearrangement of details coming within the iield of invention claimed may be resorted to in actual practice, if desired.
