COMBINED SAFETY-RAZOR. AND RAZOR- BLADE SHARPENEB.

Specification of Letters Patent.

Patented Oct. 10, 1916.

Application filed May 12, 1915. Serial No. 27,498.

To all whom it may concern:

Be it known that we, JOHN HoL'rzMAN and ABRAHAM GnrFoN, residents of the city of New York, in the county of New York and State of New York, have invented a certain new and useful Combined Safety-Razor and Razor-Blade Sharpener, of which the following is a specification.

This invention relatesto safety razors, and

its principal object is to provide a simple,

inexpensive, efficient, and improved safety razor having combined therewith simple, inexpensive, eflicient and improved .means for sharpening the razor blade thereof.

And a further object is to provide an iminafter appear.

In the accompanying drawings, Figure 1 is a general end view of the safety razor. Fig. 2 is a sectional side elevation of the razor shown in Fig. 1. Fig. 3 is a sectional plan view of the razor, taken on the line w:v-of Fig. 1. Fig. 4; is a side elevation showing the razor converted into a sharpening machine for its blade. Fig. 5 is an end elevation of the converted razor showing it in operative position for sharpening the blade. Fig. 6 is a fragmentary view of one of the details of the safety razor.

A'double-edged razor-blade 1 is placed in proper disposition upon a guard 2 for its edges 1, and a holding plate 3 is provided with a pair of pronged projections 1 which pass through openings 5 in-said blade, arranged along its center line, and also through registering openings 6 in said guard. An independent razor-handle 7 -consists of anexterio'r tube 7 having therewith in a forkedfiat metal spring 8 the ends of which project beyond the extremity 9 of said tube and form thereat extensions 10 that are oppositeto each other and perpendioular to the tube. Buttons 11 secured to the arms 8* of said spring pass through and project outwardly from the wall-of tube 7 by means of which the spring 8 is retained in place in connection with said tube. Upon pressing said buttons inwardly toward each other the extensions 10 may be made to move toward one another while releasing of said buttons causes said extensions to move away from each other to the position shown in Fig. 2. The extensions 10 are provided with openings 12 which are adapted to slip over the heads 13 of projections 4 when the but tons 11 arepressed to move said extensions toward each other, and when they thus slip over said projections and the buttons are released the edges 12 of said openings spring over to and engage the projections 4 at the interior sides of the heads 13 and thereby secure together the blade 1, guard 2, holding-plate 3, and the handle 7, rendering the safety razor in this manner completely assembled, Figs. 1, 2, and ready for shaving. Should it be desired to disassemble the parts constituting the safety razor for cleaning .or other purposes it merely requires pressing of the buttons 11 inwardly and simultaneously withdrawing the handle 7 away from the projections 4, whereupon all of the aforementioned parts at once becgme separated and may be taken apart.

To the razor blade 1 and along the center line thereof is secured a bar 14 by means of a screw 15 passing through a central opening in the blade threading into the bar, and said bar is provided with openings 16 registering with the razor-openings 5 to permit passage of projections l therethrough. At

the extremities 17 of bar 14 is pivoted a frame 18 comprising arms 19 that are pivoted to and extend from said extremities and a cross bar 20 connecting said arms. Upon the underside of cross-bar 20 are located headed projections 21 which are similar in configuration and disposition to the above described projections 41. WVhen it is necessary 'to sharpen the edges 1" of the razor-blade 1 the handle 7 is disengaged from the projections a and the holding-plate 3 with the guard 2 are entirely removed from the blade 1, and then the handle is engaged with the projections21 of frame 18. Thereupon the safety razor is converted into a sharpening machine comprising as its chief parts the handle 7,.the frame v18 mounted rigidly thereon, and the blade 1 mounted pivotally in said .frame. A retaining strap 22 bent around one of the arms .19 andslidable therealong may be slipped over the razor-blade 1, in the manner shown in Figs. 1, 6, to prevent rotation or swinging of the blade and retain it disposed in the general direction of the longitudinal axis of handle 7. After thus steadying the razor-blade 1 its edge 1 may be sharpened with the machine by moving it along a sharpening surface 28 of a stone or strap,'and the blade is maintained during sharpening in proper position angularly to the surface 23, Fig. 5, by means of guiding rollers 2% mounted in ears 25 secured to the handle-tube 7. After one side of one of the edges 1 has been sharpened the machine may be turned around oppositely and the opposite side of said edge sharpened therewith, and after the sharpening of said edge has been completed the blade may be turned around in the machine and its opposite edge similarly sharpened. All that it requires to turn the blade around in the frame 18 is the sliding away therefrom of the retaining strap 22, swinging around of the blade half a revolution, and then sliding back the strap 22 over the blade to steady it in sharpening position. When sharpening or honing the blade against a stone the machine is moved therealong in a direction which is toward the blade, and when stropping the blade the machine is moved in an opposite direction away from the blade. In order to convert the sharpening machine, Fig. a, back into the safety razor, after sharpening of the razor-blade, it merely requires to put back the guard 2 with the holding-plate 3 in place against the blade, Fig. 2, and disengaging the handle 7 fro-m the projections 21 of frame 18 and engaging it with the projections 4 of said holding-plate.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described our invention, we claim 1. A safety razor having the combination with a razor blade, and a guard therefor, of means projecting through said guard, an in dependent handle having means to spring over and engage said projecting means to secure said handle to said guard, a frame connected pivotally to said blade, said frame having means for springing over and engaging said handle therewith, and means to guide said blade angularly against a sharpening surface.
