HAIR-CLIPPER.
Application filed May 29,
T 0 all whom it may concern Be it known that I, J OHN D. Cox, a citizen of the United States, residing at Clarksville, in the county of Mecklenburg and State of Virginia, have invented certain new and useful Improvements in Hair-Clippers, of which the following is aspecification.
This invention relates 'to cutlery, and more especially to barbers hair clippers;
and the objects of the same are to improve the means for driving the clippers and the handle for holding and guiding them, to utilize an electric motor as the power unit and mount it on the back of the chair, to.
provide on said back-a hook for sustaining the cutter when not in use, and to mount on the adjustable seat of the chair a support for the rheostat controlling the current to the motor, so that the control shall be within reach of the operators foot whatever the position of the chair.
These and other objects are carried out by the invention whose preferred construction is described below and shown in the drawings wherein:
Figure 1 is a general perspectiveview of the several parts of this apparatus.
Fig. 2 is an elevation of the tool and a .section through the handle.
5 from which a flexible shaft 6 leads to thehead of the machine yet to be described. The motor is pivoted at 7 on a plate 8 which in turn is swiveled at 9 to the back-B of. a barbers chair typically shown in Fig. 5 as including a pedestal P on which the seat S is mounted for vertical adjustment .and for rotation. A bracket 10 depends rigidly from the seat and has a footll'from which rises a post 12, and'to the post at 13 is piv-- oted a contact bar 14which stands between the coils 3. Said bar is pivoted at 15 in a box 16 which rests at 17 upon the foot 11,
the latter being upturned at 18 into a toe Specification of Letters Patent.

hooked under a loop19 on the outer end of the box. The inner end of the box is held normally raised by a spring 20, and another spring 21 draws the outer end of the bar 14 normally upward. The construction is such that when the operator bears upon the top of the box, or upon the tubes 22 which incloses the cables 2 and 4, the entire box and coils are depressed so that more andmore of the resistance is cut out and therefore the current to the motor is increased, with the result that the motor will be driven more rapidly according to the foot pressure applied. The entire current controlling device is mounted on the foot 11 of the bracket or'support 10 above the floor even in the Y lowest position of the seat, and therefore no matter how the latter is adjusted the control is always within reach of the operators foot. The head of the instrument includes a peculiar handle for supporting the tool or cutter C, andthe shafting within the handle. The handle is numbered broadly 30, and it has horns 31 and 32 at its upper and lower ends for passing slightly over the edges of the operators hand so as to give him a firm grip and protect his .hand from moving On its opposite side the handle is recessed as at 33 for the reception of a fixed leg 34 of the tool which is herein shown as a hair cutter in the form of a pair of clippers C. The construction of this device is immaterial further than that it has the usual guard fingers, and a blade reciprocating rapidly across them, this blade being moved by a swinging leg 35. The fixed leg 34 is attached by screws 36 to the back of the handle, and preferably also serves to cover the head of a screw 37 whose tipengages a groove 38 in the drivingshaft 39 which is rotatably mounted within the bore or the handle. 'Beyond the latter and protected both by the fixed leg 34 and the horn 31,
the shaft carries a crank wheel 40 on whose' wrist pin 41 is pivote'd'one member 42 of'a' pitman, the second member, 43 being pivoted to the first member at 44 by a pin or screw at right angles to' the first pivot 41, i
and in turn pivoted at its outer end at 45 to a third member 46 which is mounted at 47 in the free end of the swinging leg 35. Thus when the driving shaft 39 rotates,- rapid reciprocation is imparted by the pitman to the leg 35, and the'tool C is operated.
By preference the driving shaft is made up of two sections having overlapping tongues 50 and 51 within the bore of the handle, the lower tongue being connected in an suitable way with the flexible shaft 6 an removably held in the lower end of the handle-by a sleeve 52 having a socket 53 engaged by the inner end of a screw 54:. WV hen the latter is removed or retracted,
it will be obvious that the sleeve can be drawn out of the lower end of the handle,
and with it the tongue '51 which slides out of engagement with the companion tongue pivots between the members ofthepitman the tool.
are preferably screws as shown. In this way the various parts of the structure are rendered separable for cleaning and repair.
The device is shown in Fig. 5" applied to a barbers chair. 0n the back of the same near the top is preferabl fixed a hook 59 upon which the tool C is ung when not in use, and the flexible shaft 6 then hangs pendant as shown in full lines, or if it is quite long it 'may hang lower as shown in dotted lines, its weight being suflicient to turn the motor on the swivel 9 about as shown. All parts of the structure are carried entire y on the chair excepting only thefeed cable 2 which is led away to a distant source of electric energy and will of course be long enough to permit the chair to be rotated as necessary. When a customer takes his seat, the barber removes the head from the hook 59 and puts his foot on the current controlling device which stands normally in such position that the motor is idle. Pressure thereon permits the flow of current to the motor whose rotation is thus readily controlled while leaving the barber with both hands free. Grasping the handle 30 in one hand, the horns 31 and 32 prevent it from slipping and protect his hand from the rapidly moving leg 35. The clipper C is now applied to the customers hair in a manner whichwill be clear. At any time .a decrease of pressure on the control automatically reduces the current flowing to the motor, or the removal of the operators foot permits the spring 20 to act to cut ofl the current completely and therefore stop the motion of the motor and the operation of barber to leave his osition at the chair, even temporarily, wit the cutter worlnng,
Thus it is not possible for theneamae and it is therefore safe for him to lay the cutter in the customers lap because the customer is powerless to operate the control and start the motor. While the feed cable 2 is shown as leading upward from the control, it is $iite possible to lead it into the pedestal to a socket provided purposely therein, and connect the plug 1 with such socket. That would remove every possibility that other barbers or other cus tomers could step on or become entangled with the feed cable, and would entirely localize the attachment. In any event, from the control upward to the tool, all parts of the attachment are supported by the movable portion of the chair in ready reach of the barber and yet out of reach of the customer.
While the appliance is shown herein and preferably used for attachment to the back of the barbers chair, it will of course be understood that the motor and its associated parts may if desired be mounted on a suitable stand without departing from the spirit of the invention. Also if desired, the devices may be attached to a series or gang of chairs, and several tools operated by a motor common to all. Furthermore, in so far as the details of construction of the head are concerned, it is immaterial whether the tool be employed for cutting human hair, or in fact, whether it be a clipper at all, as it might obviously be some other tool or apparatus which has a movlng member capable of being driven by appropriate connection with the shaft in the handle.
Having thus described the invention, what is claimed as new is: p
In a power attachmentfor a hand clipper having pivotally opening and closing handles of different lengths, a grip stock attached to the long handle and having a driving shaft journaled therein and projecting longitudinally beyond one end of a grip stock, a crank wheel secured to the pro ecting end of the shaft and provided with a crank pin, a clip secured to the end of the short arm, a pitman including pivotally united sections one of which is pivotally connected with the clip and the other fitted to the crank pin, and a horn projecting laterally from one end of the stock grip and forming a guard for the pitman and its associated parts, said horn' extending over the end of the short arm when the latter is in its outermost position.
In testimony whereof I affix my signature.
JOHN D. CUX.
