Description

CLIPPER Filed Jan. 29. 1925 coil.

Patented Aug. 24, 1926.

STATES LEO IT. WAHL, F STERLING, ILLINOIS.

CLIPPER.

Application led January My invention relates primarily to clippers intended for use in barber shops and in which the clipper is provided with a handle portion, by means of which it may be used, a cable or cord being provided andextending from a suitable source of current supply to the handle portion, means also being provided for switching on or off the operating current.

One object of my invention is to provide a suitable switch for the current and to locate the operating portion of the switch outside of the handle portion of the clipper and adjacent the point of entry of the current supply cable, to the end that when the clipper is in operation the switch operating device will be in such a position as to notl interfere with the proper handling and use of the clipper.

Other objects of my invention will appear and be described in the specification.

The noveltyof my invention will be hereinafter more fully set forth and specifically pointed out in the claims.

In the accompanying drawing: F ig. 1 is a plan view of a clippery embodying my invention, the cover of the case or handle being removed.'

Fig. 2 is a detail of a part of the mechanism of the switch.

'The same numerals of reference are used to indicate identical parts in both figures.

As illustrating one form of construction embodying my present invention, though Without limiting myself to the precise details of construction or arrangement of parts shown, but availing myself of all modifications and equivalents which may be made or used Within the scope of the appended claims. I have shown a clipper` oomprising a case or handle l Within which a suitable core 2 is mounted. the core carrying a coil 3 properly Wound to magnetize the core when current is supplied to the The coil is connected at one' of its terminals by a lead 4 With a switch which consists of an insulating base 5 one face of which is provided with a plurality of cams, or inclined project-ions 6, there being preferably four of such projections two of which...v at opposite sides of the base 5 are covered with contact pieces 7 and 8, the lead 9 being connected with contact piece f8. The other terminal of the coil is connected through lead 10 directly to the 29, 1925. Serial No. 5,502.

source of current supply, to which the lead 9 also extends.

The movable Contact of the switch is shown more clearly in Fig. 2 and consists of a pair of angularly arranged feet 11 attached as by legs 12 to a disc 13 which has a square opening through it as clearly shown in Fig. 2. Referring again to Fig. 1 the disc 13 engages the square o f a shaft 14, the latter carrying a collar 15, between which and the disc 13 a spring 16 is mounted to normally press the contact feet 1l into engagement With one or the other of the inclined surfaces 6.

The shaft 14 projects through the end of the case 1 and carries an operating knob 17 by means of which it may be turned.

The construction just described produces a switch in which the contact is made or broken with asnap to prevent arcing and consequent destruction of the contact members, it beng noted thatas the shaft 14 is turned, the contact feet 11 ride up the inclined projections and asthey pass the ends thereof, are snapped into engagement with the next inclinedsuface. The spring 16 causes the action of the contact portion of the -switch along the squared portion of the shaft 14.

It is to be noted that the operating knob 1T is located at the end of the handle and beside the cables '9 and 10, to the end that While the clipper is being used both the cables and the operating knob 17 will be out of the way of the operators hand and in addition, by placing the switch in the handle of the clipper, it is not necessary for the operator to reach for a lamp socket or other switch to start or stop the operation of the clipper. thus making a very convenient and eicient machine.

Any suitable armature 18 may be mounted y blade mounted at one end of the handle, a movable clipper blade cooperating with the stationary blade, electrical blade moving mechanism, current supply leads entering the handle and for supplying current to the blade moving mechanism, a current switch within the handle, and switch operating means extending outside the handle adjacent the point of entry of the current supply leads.

2. ln a clipper the combination of an elongated handle portion, clipper blades at one end thereof, electrical mechanism in the handle for moving one of the clipper blades, current supply leads entering the` handle at the opposite end from that which carries the clipper blades, a current switch in the Maceo@ handle, switch operating mechanism eX- tending through the end of the handle adj acent'the point of entry of the current supply leads.

,3. ln a clipper the combination of an elongated handle, clipper blades carried at one end thereof, electrical mechanism in the handle for operating one of the blades, a ro tating switch in the handle, current supply leads entering the handle at the end opposite from that which carries the blades', a switch operating shaft extending through the handle and a turn button on the switch shaft and outside the handle and adjacent the point of entry of the current supply leads.
