SAMPSON W. MOON, OF CHICAGO, ILLINOIS.

. ELECTRIC SAFETY-RAZOR.

Specification of Letters Patent.

Application filed October 4, 1909.

Patented Sept. 9, 1.913. Serial No. 520,835.

To all whom t may concern Be it known that I, SAMPsoN W. Moon, a citizen of the United States of America, and resident of Chicago, Illinois, have' invented a certain new and useful Improvement in Electric Safety-Razors, of which the following is a specification.

My invention relates to improvements 1n razors of the safety type, and has for .lts object the production of a device in whlch electricity is used to actuate the razor head and blade from vside to side during its use.

A further object is the production of improved means for actuating the razor head and blade so as tov provide the most efficient stroke.

A further object is the production of a device of simple construction, positive in its operation, and one that lis least liable to get out of order.

These and such other objects as may hereinafter appear are attained by my device, embodiments of which are illustrated in the accompanying drawings, in which- Figure 1 represents a front elevation of my device. Fig. 2 represents a side elevation of my device partly in section, with the razor and head removed. Fig. 3 represents a front elevation of my device partly in section, with wires removed and with the razor and head in position.

Like numerals of reference indicate like parts in the several figures of the drawings.

Referring now to the drawings: 4 represents the outer tubular casing serving as a handle, and open at its lower end and provided with a small opening 5 in its upper end. A tubular support 6 ts within the lower end `of the casing and is provided with a circumferential flange 7 fitting' snugly against the lower edge of the casing. An insulating collar8 fits within an opening in the center of the end of the support 6, permitting the passing of wires within the support.

Mounted on the inside of the support 6.

by any suitable means-21s, for instance, rivets-is a spring 9 on which is mounted a supporting bar or frame 10. This bar is turned upwardly at its upper end, and a razor stem 11 mounted thereon., .Mounted on the upper surface of the bar 10 near its lower end are two posts provided with contact screws 14-15, and an` electro-magnet .(shown as two coils 16-16)` is mounted on the bar.v .The spring. armature 17 is mount- `the razor blade.- Y course, lengthwise of the blade, so that as the razor is drawn over the face during shaved on the post 13 at a suitable distance above the magnet contacts 18, and at its upper end is provided with a hammer or striker 19y having on its striking face a rubber buffer 20. The stem 11 passes through the opening 5, and is preferably screwthreaded at its end, and a razor frame handle 22 is screwed thereon.A On this handle is mounted an ordinary safety razor frame 23 within which is fitted a razor blade 24.

The device is connected with a source of electric power, for instance a pair of dry cells (not shown), the circuit being through cord 29 to post 13, to armature spring 28, and through cord 30 to coil 16a, connecting wire 31 to coil 16, cord 32 to post 12 and contact spring 26. A switch (not shown) is conveniently located to turn the current on and off. In order to prevent theadmission of water within the casing when cleaning the razor, the razor handle 22 at its lower end is flared outwardly, forming a circumferential flange. This serves to deflect the water running ldown the handle and prevents it from passing within the opening 5.

The device may beused onthe ordinary electric light circuit, or any other source, by placing a suitable resistance (not shown)` in the circuit to prevent the burning out of the coils 16 and 16a. It will thus -be seen that as ing against the bar with each vibration, thus transmitting the vibration to the stem 11 and through it to the razor frame carrying These vibrations are, of

ing, the frame and blade are moving rapidly sidewise, giving a saw effect and aiding materially in the cutting of the beard. In the use of the ordinary safety razor the hair of the .beard is cut by a direct pull, and the operation is often very unsatisfactory, especially if the beard happens to be stiff or the razor dull. By the use of my device, however, the sidewise movement of the razor blade, moving with the frame, performs the cutting operation, the razor being drawn lightly over the face. It will be noted that, as the beard is not cut by a direct pull, the blade has to simply move slowly over the face in order to bring the moving blade against the hairs of the beard and the disagreeable pulling of the beard is entirely done away with and the user relieved om the necessity of exercising any special care or skill in the manipulation of the razor.

As the coils, posts, contact spring and armature are all mounted on the bar and the bar attached to the support vback of the posts, the entire structure vibrates when the device is in operation and the Contact spring is not aiiectedv in any Way by changes in pressure on the razor frame. This being the case no amount of pressure on the razor head can affect the operation of the device.

While I have shown an improved form-of construction,it is evident that various modications can be adopted without departing from the spirit of my invention.

I claim:

l. An electric Safety razor, comprising a handle, a razor frame, a vblade mounted thereon, and electrical means for vibrating said razor frame and blade, said means comprising an electro-magnet, an armature v adapted to vibrate independently of said razor frame, and means for impartln `said vibrations to the razor frame and bla e..

2. An electric safety razor, com risinga casing, a razor frame, a razor bla e mounted thereon, an electro-magnet, an armature, a striker mounted on said armature, means for vibrating said armature, and means for transmitting the vibrations of saidarmature striker to said razor frame and blade. 3. Anelctric safety razor, comprising a casing, a razor frame, a razor blade mount-' ed thereon, an electra-magnet, an armature, astrikr mounted on said armature, an interrupter-/in the circuit of said electro-magnet t0 vary the energization of said magnet t0 thereby vibrate said armature, and a bar adapted to be struck by said striker for transmitting the vibrations. of said armature striker to said razor frame and blade.

4. An electric safety razor comprising a casing, a supporting bar, a razor frame, a razor blade mounted thereon, an electromagnet and armature seated on said bar, a striker mounted on said armature, an electricl circuit breaker arranged tooperate said armature whereby said striker engages said bar to thereby transmit the vibrations of said armature striker to said razor frame and blade.

5. An electric safety razor, compris' a supporting bar, a razor frame and an e ectro-magnet rigid 'with said bar, a spring mounted armature adapted to vibrate independently of said bar, and means for imparting the vibrations of the armature to the supporting bar and razor frame.

6. An electric safety razor, comprising a razor frame, an electromagnet and a supporting'ban'for sald frame and magnet, a spring mounted armature for said electromagnet adapted to vibrate independently of said razor frame, and astriker attached to said armature adapted to strike said supporting bar whereby the razor frame may be vibrated b the operation of said armature.
