RUSSELL E. WAKELEY, OF ST. LOUIS, MISSOURI.

' SAFETY-RAZOR.

specification of Lette-rs Patent.

Patented Sept. 26, 1916.

. Application led August 28, 1915. Serial No. 47,773.

To alli/.17mm it may concern Beit known that I, RUSSELL E. WAKELEY, a citizen of. the United States, residing at the city of St. Louis, Sta-te of- Missouri, have Vinvented certain new and us'eful Improvements in Safety-Razors, of which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

This invention relates to certain new and useful improvements in safety razors, the object of my present invention being to provide a comparatively simple and inexpensive razor especially of the kind stated having areciprocating blade, whereby the act of shaving is quickened and facilitated.

With the above and other objects in view, my invention resides in the provision of a razor having a reciprocatorily movable blade and in certain novel features of form, p

construction, arrangement, and combination of parts, all as will hereinafter be described and afterward pointed out in the claims.

In the accompanying drawing, which illustrates my invention in preferred form, Figure 1 lis an elevational view of Aa safety razor embodying my invention; Fig. 2 is an enlarged fragmentary longitudinal sectional view through the same; Fig. 3 is an enlarged elevational view of my new safety razor with several of the parts thereof in assembling v position; Fig. 4 is 'a view taken approximately on the line 4 4, Fig.. 2; Fig. 5 is a transverse sectional view taken through the handle of the razor on approximately the line 5 5, Fig. 2, looking in the direction of the arrows; Fig. 6 is a plan' view of the razor-blade forming part of my new razor; Fig. 7 is an inverted plan view of one of the razor-blade guard-and-securing plates; Fig. 8 is a' sectional view through the lower portion of the handle of the razor, showing in section the razor-blade reciprocating or actuating means; Fig. 9 is a View taken approximately on the line 9 9, Fig. 8; and Fig. 10 is a view taken approximately on the line ic-lo, Fig. s.

teriorly therefrom, is a rotatable rod or shaft 2, a bushing or the like 3 being preferably provided in handle 1 at the projecting end of shaft 2, as seen in Fig. 2. Fixed upon shaft 2 at its projecting upper end is a small arm or tappet 4, handle 1 at its upper end .being provided preferably integrallyT with'a pair of diverging or oppositely disposed obliquely outwardly presented arms 5 5 having perforated extensions 6 6.

7 indicates a suitable end or blade-securing plate, whichis preferably, as is usual, transversely convexed on its outer face. Fixed upon the plate 7 at its opposite or inner face is a pair of preferably square -headed threaded studs or bolts 8 '8 adapted, when the several parts are operatively assembled, to project through handle-extensions 6 6 to receive securing-nuts 9 9.

10 indicates a suitable guard.- and bladesecuring plate, which is provided at its opposite lengthwise edges with dull or faceprotecting teeth 11. Transversely plate 10 is provided with suitable perforations or openings 12 12 adapted to freely accommodate the studs 8 8, plate 10 being further centrally and intermediate perforations 12 12 provided with an enlarged opening or aperture, as at 13, to accommodate the passage through plate 10 to operative bladeengaging position when the parts are being assembled, of arm or tappet 4.

Adapted tooperatively loosely or .movably t between plates 7 and'10, is a blade 14 approximately rectangular in shape in plan view, as illustrated in Fig. 6, bla-de 14 being sharpened to a cutting edge, as at vided with rectangular slots 1(3 16 to accommodate and it the squared portions of studs 8 8, and centrally intermediate slots 1,6 16 blade 14 is provided with an enlarged opening or aperture 17 within which tappet 4 is adapted to fit and work when the parts are operatively assembled. Extending into the area of opening or aperture 17 is a pair of diametrically opposite teats 18 18, as clearly seen in Figs. 4, 5, and 6; aperture 17, instead of having a regular outline or perimeter circular in form, may thus be described ashaving a wall somewhat irregular or non-circular in outline. With the teats 18 18 or the otherwise so-called irregular outline orv Wall of aperture 17 tappet 4 is adapted t0 alternately engage, as shaft 2 is rotated, to reciprocate blade 14:. It will be noted that, while blade 14 is of somewhat greater width than the width of outer or end-plate 7, it is of somewhat less width than the width of inner or guard-plate 10 with its teeth 1,1, teeth 11 being adapted to protect the face from injury by the cuttingl edges 15 of blade 14 when the razor is in service, as in the act of shaving, as will be well understood.

Suitably fixed upon handle 1 at its other or lower end, and surrounding the lower end of shaft 2, is a preferably cylinmcal housing or casing 19. Projecting into housing 19 and loosely fitting in shaft 2 at its lower end, is a spring-winding button or the like 20, fixed upon the shaft of which within housing 19 is a ratchet-wheel 21. Loosely mounted upon shaft 2 within housing 19, is a gear-wheel 23 having preferably a lwidened hub-portion 24. Arranged within housing 19 and surrounding hub-portion 24 of gear 23, is a spring-barrel or casing 25, provided within which is a suitable coil spring 26, one end of spring 26 being fastened-to casing 23 and its 'other end to hubportion 24 of gear 23. Ratchet 21- and spring-casing 25 may be formed integrally or otherwise xedly connected one with the other.

Mounted in suitable bearings 27 in housing 19, is a small shaft 28, xed upon which to mesh with gear 23 is a pinion 29. Also fixed on shaft 28 is a gear 30 adapted to mesh with a. gear 31 fixed on main shaft 2, gear 31, in turn, meshing with a gear 32 mounted on a shaft 33 supported in suitable bearings 34 in housing 19.

In use or operation, the blade 14 with its securing and guard-plates 7 and 10 are operatively mounted on handle 1 by means of studs 8 and nuts 9, as will be clear, slots 16 permitting' movement of blade lll between said plates. YVith blade 14 in such position,

tappet 4 nts in perforation 17 to engage with said projections- 18. A pin 36 being now pressed inwardly to engage shaft 2 to frictionally prevent rotation of shaft 2, spring 26 is wound within its casing 25 through rotation of its winding-member 20. On pin 36 being released, as in the act of shaving, shaft 2, through said train of gearing described, will be rotated, Iwhereupon blade 14;, through alternate engagement of tappet it with said projections 18, will be reciprocated relatively to handle 1, the act of shaving being thereby quiokened and facilitated.

Pivoted upon the lower wall of housing 19 is a pair of oppositely disposed springpressed dogs 22 adaptedv to engage with. the teeth of ratchet 21 to prevent reverse rotation of ratchet 21 and its connected springcasing 25 under the influence or tension of spring 26, and to prevent too rapid rotation of shaft 2 under the tension of spring 26, I

preferably provide in connection with gear a centrifugal governor 35 of any standard or approved construction adapted to frictionally retard rotation of gear 32 and.

its connected gearing, as will be obvious.

I am aware that changes 1n the form, construction, arrangement, and combinatwn of the several parts of my new razor may` be made and substituted for those herein shown and described Withou-t departing from the nature and principle of my invention.

Having thus described my invention,`

what I claim and desire to secure by Letters Patent is:

1. In a razor, a handle, an end-plate, studs on said end-plate connected to said handle, a guard-plate on said studs between said end-plate and handle, said guard-plate having an opening, a blade niovably mount ed between said plates, said blade having slots for accommodating vsaid studs, a central opening registering with the opening of said guard-plate, and a pair of diamet rically opposite tea-ts projecting into the area of its opening', a rotary shaft in said handle projecting at one end into said registering openings, an arm on said shaft itting in the opening of said blade and adapted to alternately engage with said teats on 4rotation of said shaft, and means for rotating said shaft and its' carried arm.

2. In a razor, a handle havingr a pair of diverging extensions, an end-plate, a guard-1 gether, and means for rotating said shaft and its carried arm to reciprocate said blade. In testimony whereofI have attached my name to this specication.
