Application filed January 18, 1917. Serial No. 143,139.

To all whom it may concern:

Be it known that I, GEORGE H. TUTTLE, a citizen of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented certain new and useful Improvements in Razors, of which the following is a specification.

This invention relates to safety razors and has as its object to provide an electrically op erated safety razor embodying a movable lblade, and means i for vibrating the said ade.

The invention aimsto provide an'electrically operated safety razor which will be compact, convenient to handle and not liable to get out of order or require adjustments.

" Another aim of the invention is to provide in a razor of this class a novel form of switch which will permit of the current being quickly and conveniently turned on and off while using the razor.

In the ccompanying drawings:

Figure 1 is a longitudinal sectional view through the razor embodying the. present invention, the section being taken on a plane from front to rear;

Fig. 2 is a vertical transverse sectional view through the upper end of the razor;

Fig. 3 is a horizontal sectional view on the line 33 of Fig. 1;

Fig. 4 is a group perspective view illustrating the core of the solenoid which constitutes the actuating means for: the blade of the razor, and the parts associated there with; l

Fig. 5 is a similar view of the parts comprising the switch of the razor;

Fig. 6 is a perspective view of the cap plam for the blade supporting head of the razor;

Fig. 7 is a group perspective view illustrating the blade carrier and the blade to be carried thereby.

Briefly stated, the razor embodying the present invention includes a head which is arranged at one end of a handle and which supports the razor blade holder for reciprocatory motion and the said handle has a sole noid so connected with the blade carrier that when the solenoid is energized and deenergized by an alternatin current vibratory motion will be imparte to the said blade carrier. The ha die is preferably formed in two sections each of which is substantially semi-elliptic and hollow, the upper or forward section being indicated by the numeral '1 and the other section being indicated by the numeral 2. These sections may material and at sponding end of the other section is snugly fitted. At its minor end, the section 1 of the handle is exteriorly threaded, as at 4:, and removably fitted thereto is the end of a relatively short shank or neck 5 which is secured to the underside of the head of the razor by means of screws 6, the shank 5 having its upper end inclined or disposed at an angle to the axis ofthe said shank and the said supporting head, indicated by the numeral 7 responding to the inclination of the said end .ofthe shank 5. or a purpose to be presently explained, the head 7 is formed in its upper side with a dove-tail recess 8 extending from the front to rear edge of the said head and also for a purpose to be presently explained the said head is formedwith a slot 9 communicating with the said recess. The blade holder or carrier comprises a plate 10 preferably substantially rectangular but increased in thickness gradually from its rear to its forward edge, the plate being formed at its said forward edge with a number of guard fingers 11 similar to the guard fingers of the ordinary safety razor blade holder. Upon its underside this plate is provided with an integral rib 12 which extends from front to rear of the said plate and which is dove-tailed so as to slidably fit within the groove 8. The razor blade is indicated in general by the numeral 18 and the same has a cutting edge 14, the blade being formed in its opposite end edges near its forward corners with notches 15 receiving studs 16 upon the upper face of the holder or carrier 10, the rear edge of the blade being engaged by a cam latch 16' mounted upon the said upper side of the holder or carrier 10,

' the blade being in this manner clamped to the said holder or carrier. By reference to Fig. 7 of the drawings it will be observed that one of the studs is located nearer the forward edge of the holder 10 than the other and that the notches in the blade are correspondingly located so that the cutting edge of the blade will not extend at a true right an 1e to the front to rear median line of the boiler but will be slightly inclined so that the member 1 to which flange the correthe cutting edge of the blade will act more circuit is broken, the spring 24, having been effectually when the razor is in use. In its compressed in the downward movement of reciprocatory motion the carrier is guided the core, will be free to expand and in so by the upper ends of the screws 6 which are doing will draw the cbre upwardly. Mountleft unthreaded, as indicated at 17, and ed for rocking movement, as at 35, within 70 which project into short slots 18 formed in the shank is an angle lever including an the said carrier 10. arm 36 and an arm 37 and the said arm 36 It will be observed by reference to the is pivotally connected, as at 38, with the drawings that the cutting edge of the blade head 33 of the stem 32 and the arm 37 ex- 14 is presented toward the guard fingers 11 tends through the slot 9 and engages at its 7 but is suitably spaced from the ends of the end in a socket 39 formed in the underside said fingers and in order to substantially of the rib 12 of the blade carrier. It will cover the blade and prevent the same comnow be understood" that as the solenoid ising into contactwith the skin in such manrapidly energized and deenergized, recipner as to cut the same, the head is provided rocatory motion will be imparted to the core with a cap plate or cover comprising a top 29 and as a result rocking motion will be 19 and depending sides 20, the said top at imparted to the angle lever so that in such its forward corners being provided with movement ofthe core the blade carrier will downwardly curved extensions which engage be reclprocated. 1 I

Contacts 50 are fixed within the limited by a fixed core section, indicated by lower ends of the socket 47 and when the the numeral 30, and located within the lower member 48 is fittedthrough the openlng 49 126 end of the said spool. A disk 31 is disposed the projecting lower ends of the contacts 45 at the upper end of the spool 24 and threadwill electrically engage the contacts 50, as ed into the upper end of the core 29 is a shown in Fig. 1.

It will now be understood that 130 when the ferrule 52 is grasped and rotated, rotary motion will also be imparted to the member 42 and as the member 42 is rotated the contacts 45 will be brought into electrical contact with the spring contact fingers- 40, thereby closing the circuit, when it is desired to break the circuit the ferrule 52 may be again rotated so as to bring the other opposite faces of the portion 44 of the member 42 into position for engagement by the upper ends of the contact fingers.
