STRAIGHT-HANDIED VIBRATORY RAZOR.

Application led November 21, 1924. Serial No. 751,225.

This invention relates to safety razors of the class in which a relatively thin blade is confined upon a base constructed With guard fingers, and usually referred to as the comb, by means of a removable cap; the blade being held against displacement in the plane of the razor by means of pins fixed upon one of the confining members and passing through openings in the blade.

ln my application, Ser. No. 678,136, filed December 3, 1923, I have disclosed a razor with a blade and mounting arranged in this manner, but in which the handle extends from the mountinglr in a direction substantially perpendicular to the plane of the blade, the blade being' arranged to vibrate upon the mounting by having the openings Which receive the fixed pins elongated in the direction of vibration, and the handlebeing equipped with electrically energized vibratory mechanism, one element of which extends from the handle in a position to impart vibration to the blade.

The primary object of the present invention is to adapt a suitable vibratoi'y mechanism, for instance, that described in my application `above identified, to a razor having its blade mounted in substantially the manner aforesaid, but' in which the handle is in the nature of a shank or shaft extending ina direction substantially parallel to the plane of the blade after the manner of a so-called straight razor; and accordingly one feature of the present invention consists in mounting Cil als

a vibrator at or near one end of a laterally ofisetting shank or handle and the vibratory razor blade at the other end thereof, While the intermediate portion of the shank serves for prehension in the manipulation of thel razor; and connecting the transmitting member of the vibrator with the blade through means of a longitudinally reciprocating thrust member mounted in the handle or shank and provided at its respectivel ends with means for establishing driving connection with the blade and the transmitting member.

A further object to provide a design of connecting rod which Will be very cheap to produce in accurate form, very light in structure, readily responsive to vibratory force and very conveniently assembled and disassembled with the shank or handle and with the elements with which it cooperates at its respective ends. Accordingly another fea-. ture of the invention consists m constructing the shank or handle in tubular form, preferably of two members united through longitudinal tongue and groove'joints so that one slides into position upon the other, and confining the connecting rod in the housing thus provided and between the said members thereof in a manner to guide it in its right-line movement Without imposing undue frictional or other resistance to its action; the en'd of the connecting rod which receives the vibrating element being fashioned 'in the form of a yoke which embraces said element when the vibratory mechanism is placedV in position upon the handle, and the end of the connecting rod Which'drives the blade being in t-he formof a slide fitted in a bed formed in the guard and carrying a stud which projects through acentral opening in the blade.

A still further object is to coordinate the the shank and the other by the vibrator, rotatable one Within the other, and of Which the inner cylindrical member is circumferentially slotted to admit the actuating end of the vibrator to the yoke of the connecting rod, and

permit said inner cylindrical memberto ro tate in the aforesaid right and left hand adjustment of the razor; to which end, the yoke is likewise laterally open to the admission of the operating end of the vibrator through an angle of at least 180. Preferably,l kthe inner cylindrical member is held Within the outer member by means of a plug united to the end of the inner cylindrical member in a manner to impart turning movement thereto, and said plug is fashioned in a manner to constitute it a convenient means for impartingy the rotation incident to the right and lefthand adjustment referred to.

Another object is to provide an improved driving connection for a vibratory razor blade of the type in which the blade, instead Fig. 1;

of being mounted on a carriage Whiclris guided for reciprocation, slides directly upon aiixed base upon which it is guided by pins extending through velongated holes in the blade While receiving its drive from a stud intersecting its center, which driving connection Will be substantially free from tendency to displace the blade from its axis of reciprocation, and therefore impose less Wear upon the guiding pins and less load upon the motor. Accordingly, another feature consists in providing at the center of the blade, and intermediate of its elongated guiding openings -which occur near its ends, a hole for the driving stud, which is of relatively large diameter as compared with the transverse diameter of the guiding openings and the Width of the blade, the diameter of this driving hole being preferably somewhat more than one-third of the Width of the blade, With the result that a superior driving effect is insured, there is substantial reduction in the tendency to cause sidel impingement of the blade upon the aligning pins, and the arrangement admits ofthe use of a more stable driving stud.

Further objects relate to details of construction Which are particularly appropriate to the economical realization of the several objects already stated, and will be fully understood from the ensuing detail description.

In the accompanying drawing Fig. 1 is a side elevation of a straight handled razor With the confining cap removed and a portion of the handle in section, in an intermediate longitudinal plane of Figure'2;

Fig. 2 is a section on line 2"- of Fig. 1;

Fig. 3 is a transverse section on the line 3"-8 of'Fig. 1; Y

Fig. 4 is a section on the line 4".-4" of Fig. 5 is a section on the line 5*-5* of Fig. 1;

Fig. 6 is a section .on the line 6"-6 of Fi l; and A lig.v 7 is a section on the line 7"- x of Fig. 1.

Figure Sis a detail View of the spring clip that secures the cap to the blade mounting.

1 represents the baseof the blade mounting, which is constructed with' guard fingers 2, and which will be hereinafter referred to as the comb. 3 represents the blade resting upon the comb 1 'and confined againstvdisplacement in the plane of theblade by means of the pins 4, fixed in the comb; and 5- represents the cover which contines the blade upon the comb and which is removably secure-d in place by means o f a clip- 6 having key hole slots 6a (Fig. 8), which engage the necks 7 of the pins 4 and hold the cap at a fixed distance from the comb, thereby coniining the blade without resisting its free-- dom of vibration. Preferably the cap 5 rests firmly upon the heads of the pins 4, which thus become the means for spacing the cap from the comb, and the clips 6 have suiicient resiliency to draw the cap snugly against the pins. 8 represents the handle which is in the form of a shank extending from the comb 1 substantially in the plane of the blade and thus adapting the razor to be manipulated after vthe manner of a so-called straight razor. The handle 8 is constructed of the shank 9 which extendsnfromethecomb and which is made trough-shaped for the dual purpose of lending rigidity to the structure and providing a portion of the housing for the connecting rod 10 that is to transmit Vibration to the blade; also a cover member 11 which interlocks with the shank 9, by a sliding movement, and through the `medium of tongue and groove joints 12. Shank 9 terminates at its outer end in a cylindrical ferrule 13 embraced by a sleeve 14, Which equips the handle for receiving a vibrator, for instance, the vibrator 15, constructed substantially in accordance with my application hereinbefore identified; and the ferrule 13 is secured against axial displacement in the cylindrical sleeve 14 through means of a shouldered plug 16 entering the outer end of thel sleeve 14 and at the same time abutting against the same, and a screw 17; the end of the ferrule 13 being constructed `with a pair of segmental Walls 18, best shown by dotted lines in Fig. 6, which are lapped by the head of the screw, and the plug 16 being provided with a noncircular neck 16a that enters the opening left between said Walls 18 to adapt the plug,

' through its perforated end 16", to rotate the ferrule 13 and through it the shank 8\ and head 1 of the razor.

Sleeve 14 provides for convenient assembly of the vibrator 15 through means of a threaded bushing 19 fixed in the boss 2O of the sleeve and with which the vibrator 15 engages through the medium of its threaded end 21. A

The connecting rod 10 confined in the tubular handle, as explained, is constructed on its outer end with a yoke 22 presented in position to receive the vibratory element 23 of theA vibrator 15; said yoke 22, as better shown in Fig. 5, being designed to substantially iit and be guided in the ferrule 13, and being laterally open for at least 180 around its longitudinal axis to permit turning relatively to the vibratory element 23 in revolving the razor, and the said ferrule having an arcuate slot. 24 to admit the said vibratory element 23 Within it, and extending circumferentially a distance which permits at least one hundred and eighty degrees of angular adjustment of the vibrator relatively to the plane of the razor blade. The inner end of connecting rod 10 is designed with a slide 25 iitted in a guide bed 26 which constitutes the bottom of the guard 1; and this slide 25 has a stud 25a fixedly mounted in it in position to extend through the blade 3 and thus serve as means for connecting the blade with the slide and causing the blade to partake of the slides vibration.

In assembling the several parts as above described, the sleeve 14 being longitudinally fixed by means of plug 16 and screw 17 relatively to the ferrule 13 on the shank 9, and the vibrator 15 being removed, theconnecting rod 10 with its slide 25y is first placed in position with its slot b engaged over a pin 4, which brings the slide in its bearings in the bed 26, and presents its yoke 22 in position to receive the vibratory element 23. Cover member 11 is then slid longitudinally along the shank 9, until its end 11a (Fig. 2) brings up against the ferrule 13. The blade 3 is then place-d in position with the posts 4 and the stud 25a projecting through it, and cap 5 is put on and slid longitudinally to- Ward the cover member 11 until it abuts against it. Vibrator 15 may be screwed into position at any time after the yoke of the y connecting rod 10 has reached position to receive vibrator member 23.

When thus assembled, the razor is supported by the vibratory housing 15 and turned, it' necessary, to reverse the presentation of the facial side of the comb 1 to suit the convenience of the user, and it is then manipulated in the act of shaving through the medium of the handle 8, such reversal to position being repeated as often as is necessary. y j

The device constructed and assembled, as herein described, is peculiarly adapted for production largely by shaping sheet metal of suciently thin gage to insure lightness of the parts and thus the construction and assembly are made very cheap and efficient in use.
