CLIPPER.

Application led June 3, 1926. Serial No. 113,412.

This invention relates to improvements in clippers, particularly adapted though not necessarily limited in its use in barber shops, and one of the objects of the invention is to provide an improved device of this character wherein the actuating mechanism embodies an electro-magnet which controls the vibration of an armature, both the armature and magnet being located within the handle of the device, the clippers being operated by means of the electro-magnet to which alternating current is supplied.

A further object is to provide in a clipper of this character, improved means whereby a vibrator or massage device may be readily connected to the armature and improved means for controlling the extent of movement of the armature under the influence of the electro-magnet in accordance with the work to be performed by the device.

A further obj ect is to provide an improved device of this character which will be of a simple and compact construction, effective and efficient in operation, and of a size and shape convenient to be readily handled by an operator.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists 1n the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating this invention andin which Figure 1 is a top plan view of a devlce of this character constructed in accordance with the principles of this invention.

Figure 10 is a detail perspective view of the armature.

Figure 1'1 is a detail plan view of the spring washer for maintaining the controlling member for the armature in its adjusted position.

Figure 12 is a detail perspective view of a vibrator attachment. Referring more particularly to the drawings the numeral 15 designates an open casing of any desired size and configuration, at the forward end of which is secured a stationary cutter member 16, the latter being preferably arranged at an angle to the longitudinal axis of the casing and being provided with teeth 17, usual in cutters of this character. Reciprocating upon the cutter member 16 is a cutter 18 which is guided in its action preferably by means of a member 19 secured thereto and which operates in a groove 20 in the upper face of the member 16.

Arranged within the casing 15 is an electromagnet 21, the core 22 of which is provided with a slot 23 through which a screw 24 passes and by means of which screw and slot the electromagnet is adapted to be adjusted laterally Within the casing. An armature 25 is provided for reciprocating t-he cutter blade 18. connected with it a spring member 26 and the armature is mounted for vibratory movement by means of a screw 27 which passes through an opening 28 in the armature and is threaded into a post 29 within the casing 15.

The screw 27 co-operates with a clamping member 27a that rests upon the bottom of the casing to hold the armature and spring against movement about the screw 27 as a pivot.

The armature is supported adjacent one end thereof and the other extremity of the armature is preferably reduced as at 30 and is rounded as at 31 upon its lower face, thereduced portion 30 being arranged at an inclined angle to the armature and projecting over the blade 18 and spaced therefrom.

A leaf spring 32 is secured by one end as at 33 to the blade 18. The other end of the spring is shaped to form an open seat 34 having slots 35 in the walls thereof and tlie bottom of the seat is spaced above the adjacent face of the blade 18 and is rounded to conform to the contour of the rounded lower face 31 of the portion 30 of the armature. The reduced portion 30 of the armature 25 rests within the seat 31, and a pin 36 passes This armature has A through the lend 30 of the armature and enters the slots in the leaf spring 32. The spring and the pin 36 form a resilient connection between the blade 18 and the armature 25. The stress of the armature upon the resilient member 32 serves as a means for holding the plate 18 against the stationary plate 16 and at the same time the armature will have a free movement with respect to the blade 18. The curved surfaces 31 of the portion 30 of the armature and the correspondingly shaped seat in the resilient member 32 will permit the armature and reciprocating blade to relatively rock and thereby insure an equal pressure upon both ends of the reciprocating blade. With this construction the armature may be short and stili' and adapted to spring only in directions towards and away from the magnet, and the spring 32 will provide all the necessary spring or tension 0n the blade 18.

'The stress of the spring 32 may be varied by raising and lowering the end 30 of the armature. This is accomplished by swinging the armature about the pivot formed by the screw 27 after the screw has been loosened.

Any suitable means may be provided for thus adjusting the armature but a simple and eiiieient means vembodies a threaded socket 37 projecting from the other end of the armature. This 'socket is disposed between spaced lugs or posts 38 in the casing 15 and a screw 39 is threaded into the socket. The screw is provided with an open circumferential groove 40 in the body portion thereof, and stationary pins or lugs 41 carried by the posts 38 extend into the groove 40 of the screw 39 so that the screw will be held against longitudinal movement but when the screw is rotated in any suitable manner, the socket 37 will be moved longitudinally of the screw,

with the result that the armature 25 will be rocked or moved about its pivot.

lVhen the socket end of the armature is elevated the extremity 30 will be depressed and this will increase the tension upon the spring 32, likewise when the socket end 0f the armature is depressed the extremity 30 of the armature will be raised and the tension of the spring 32 will be decreased.

The eleetromagnet 21 receives its supply of electric current through suitable conductors 42, and these conductors are arranged within the casing 15 and are threaded through an opening 43 in the post 38, a controlling switch 44 being provided within the casing for controlling the current to the magnet.

It will be thus noted that with this improved construction when the electromagnet is energized the armature 25 will be attracted and the extent of this movement of the armature will be controlled by the engagement of a portion 45 of the armature with a portion 46 tracted against the stress of the-spring 26. When the electromagnet is deenergized the armature will return to its normal position.

This vibration of the armature 25 will impart a reciprocating movement to the blade 18.

A cover .47 is provided for the casing and this cover'is .provided with a projection 48 at the forward end thereof and one or more projections 49 on the edge of its body p0rtion, and which projections serve as a means for properly positioning the cover upon the casing, the projections 49 being adapted to enter a suitable recess 50 in the Wall of the casing.

A separate vibrator or implement 51 is provided lfor use in connection with this device, whereby the device may be employed for operations other than clipping operations, and this attachment is adapted to be applied without disconnecting any of the parts of the cutter or clipper mechanism.

To that end the attachment 51 is provided with a stem 52 having a threaded extremity 53 adapted' to be threaded into a socket 54 carried by the armature 25, and which socket opens laterally of the armature, the casing 15 being provided with an opening 55 in alinement with the socket 54.

The attachment 51 is adapted to be connected by passing the stem 52 through the opening 55 and threading the extremity of the stem into the socket 54.

In use, a long stroke should be given to the armature when using the vibrator attachment, whereas when the implement is used aS a clipper it is desirable to impart a shorter stroke to the armature. The vibration of the armature is adapted to be controlled by means of a screw device 56 which is threaded through the cover 47 and is preferably provided with a fibre element 57 secured to' the end thereof. The extremity of the screw 56 is adapted to engage a surface 58 carried by the armature 25 and formed in any suitable manner, the surface 58 being provided adjacent the free end of the armature.

When the vibrator is employed the extent of operation of the cutter blade will serve as an indicator to indica-te the force of operation of the vibrator.

l/Vhen the device is used as a. hair clipper, the vibration of the armature may be reduced so that the blade 18 will travel 'the proper distance and this is accomplished by applying a light downward pressure upon the free end of the armature by forcing the end of the screw 56 againstthe surface 58, this will result in an increased frictional pressure between the end of the screw 56 and the surface 58 on the armature.

When it is desired to produce a longer stroke to the armature this pressure of the screw 56 upon the surface 58 is relieved.

It will therefore be manifest that both implements, although they have different functions and operations, are controlled in their operation by the adjustment of the screw 56 to regulate or control the extent of vibratory movement of the armature.

As a means for holding the screw in its adjusted position a spring washer 59 is provided which is secured adjacent the lower face of the cover member 47 and is held against rotation-'by means of an anchoring pin 60.

The washer 59 being of a spring construction, will grip the threaded' shank of the screw 56 andv will frictionally bind or retain the Screw in its adjusted position and thereby prevent the same from Working loose under the vibration of the armature.

The fibre element 57 engaging the surface 58 operates to reduce friction.

As a means for providing an extended portion into which the screw` 61, which secures one end of the pole iece 22, passes (see Figure 8) the bottom o the casing 15 is provided with an upstanding threaded lug 62 which enters a recess 63 in the pole piece 22.

With this improved construction it will be manifest that the device is adapted to be converted from a clipper into a vibrator or massage device without interfering with or dismantling any of the parts of the clipper.

This is accomplished by simply attaching the element 51 to the armature.

When desired to use as a clipper, the element 51 may be readily removed.
