To all whom it may concern:

Be it known that I Emma I. YOUNG, a citizen of the United 'States, residing at g fontclair, county of Essex, and State of ew useful Improvements in Safety-Razors, of which the follow is a specification.

My invention i efiites to improvements in safety razors.

One of the objects of my invention is to provide a safety razor in which the bladeolding means can be quickly and positively adjusted so that the cuttin edge of the blade may lie obli uely to t e direction of movement of the b ade to give ashearing cut.

Another object is to provide a safety razor in which the handle can be rotated and posi tiv ely ad'usted at any angle to the cutting ed of t e blade.

other object is to provide a safety razor in which the blade can be quickly removed or re laced.

0 er objects and advantages will be apparent from the detailed description to 0 One form of my invention is illustrated in the accompanying drawings forming a part of the specification, in which,

Figure 1 is a front view of the same. Fig. 2 is a side view. Fi 3 is a back view. Fig. 4 is an enlarged bac view of the clampingplate. Fig. 5 is an enlar d front view of the bedlate with the bla e in situ. Fi 6 is an en arged sectional view of the hea of the razor taken on line XX of Fi 3, looking in the direction of the arrows. %ig. 7 is an enlarged view of the inner flattened end of the handle showing the two lugs or pins to engage the rack on the clampingate. p Similar letters of reference refer to similar parts throughout the several views.

Referrindg to the drawings, the bed-plate 1 is provi ed at each end with

flanges

2, 2, and at each lower corner with upturned

flan 0r shoulders

3, 3, to receive a blade 4. ese flan es or

shoulders

3, 3, are preferably forme by punching up the metal of the bed-plate 1 and are adapted to receive the lower ed a stop and ar for each corner of the blade. This lade is adapted to be held in place by a clamping-plate 5, the edges of which are arranged to be engaged by the Jersey, have invented certain'new and secured togetherv by the screw 22.

of the blade 4, formingv shaped clamping-plate 6 is provided with a pro ection or gortion 6 curving rearwardly and downwar lyuntil it-is substantially parallel with the inner faceor-

bodyvportion flanges

2, 2 of the bed-plate 1.. The U- a plurality of depressions 9, 9. These de-F-GE pressions 9, 9 are preferably formed by punching up the metal of the ro'ection or part 6. The inner end 11 of t e andle 10 1s flattened and extends at an an 1e to the remainder of the handle, and is a apted to enga the pro gection or part 6 of the clamping-p ate 5. his end 11 is provided with a non-threaded central hole 12, and a plurality of pins or projections 13 13 arranged to engage. the depressions 9, 5 o the rack 8. These pins or

pro'ections

13, 13 are likewise preferabl forme by punching up the metal of the en 11.

In the preferred form of my invention, the handle is formed in two

sections

20, 21, Means the end 11 of the are (plrovided for holdin han 10 in pivotal an frictional engagement with the projection or part 6 o t e clamping-plate 5, and also the several, parts of the devlce'in operative relation with each other, said means being at a fixed angle to the blade. In the form of my invention, as shown, such means are arranged perpendicularly' to the blade, a d consists of the thumb-nut 14 havinga sc w-threaded stem 15, which is adapted to ass throu h the hole 12 and engage the t readed ho e 7 in the projection or part 6. Surrounding the screw-threaded stem 15 and secured to the nut 14 is the spring 16 adapted to lie in the annular groove 17 in the mner face of the thumb-nut 14, whereby the end 11 is held in yielding en agement with the projection or art 6 of tEe clamping-plate. The stem 15 1s also arranged to ress the bed-plate 1 'ingflthe bed-plate is provided with a guard of a rearwardl curved extension 18 in with said -plate and 1:32? a pl 'ty of holes 19 therein. If d however other forms of ards may be The'parts when assembled are in operative relation to each other, as shown in the dra -When it is desired to remove the e for'cle'aning, renewing or other p the nut 14 is loosened sufliciently to 0w the bedlate 1 and the blade 4 to be removed toge er without dis-assembling the other parts. To reinsert the blade, it is placed s111 pr;dth&bed-pl:ll;e 1 and theylare er 1 tween ecam in -p ate fiiid the eiid of the stem 15. The slumbnut 14 is then tightened sufliciently to enage the bed-plate 1 to hold the same and blade 4 firmly against the clamping-plate 5. During the forigoing operations, the sprin 16 maintains e inner end 11 of the hand e 10 in yielding enga ment with the gil'lojection or part 6 of the c amping-plate 5. e handle 10, being in ivotal and frictional engagement with, t e projection or part 6 of the clamping-plate, may be swung to any desired position so that the handle' may assume any a le with relation to the cutting ed? of the lade. The

pins

13, 13 t e rack 8 form co-acting means for maintaining the handle in the position to which it is moved.

As will ap r from the foregoing, the handle may g revolved bodily about the stem 15 as an axis through an arc of 360,

or more, and held in positive adjustment at any desired angle to its normal-position (as shown in Fig. 3) b the

pins

13, 13 enga ing the rack 8. The handle will thus rivo ve about an axis at an angle to and lying outside of said handle.

While I have shown and described one s ific form of m invention, it will be 0 vious to those ed in the art that various changes, modifications, alterations and substitutions may be made therein, without departing from the spirit or scope of my invention.

What I claim as new, and desire to secure by Letters Patent, is:
