To allsoho'mt't myconcem:

Beit known that 1, WILLIAM N.-Wsnn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain 6, new and useful Improvements in Safety-Razors, of

- which the following is a specification. My invention relates to safety razors and has for its objectthe provision of a' device in which the blade 7 holder is formed as an extension of the handle and the ill) v removable blades are provided with recesses in their 'endsthat are engaged by headed pins on the blade.

older, one of said pins being slidably mounted ina with ascre'w shank on which is mounted a nutter securingitinposition or hold the blade.

Theoonstruction and operation oi my safety razor will'be described indetail hereinafter and I illush'atedin the drawings in'whichl is a plan view of niyimproved razor show- I ing the blade in position, Fig. 2, a cross section on the line H of Fig; 1, Fig. 3, across section ofthe handle, Fig. {ya detail view of the locking pin, and Fig. 5, a

'plan view oitheblade. I x In the similar reference characters indicate correspdndi ng' parts throughout the several views; I The handle 1 of my improved razor is preferably i made hexagdnal in cross section as shown in the drawreceives the little finger of the operators hand while I shavingand is also used for hanging up the razor when not in use; 4 As-shown in the drawings the handle 1 is a i beveled to the thickness of the ring 2 as indicated by 3. All The blade holder 4 is formed with handle 1 which is beveled as dhown at the thickness of a shank 6 connecting said handle and holder. The side edges ofthe holder 4 is formed with guard teeth 7.

A pin 8 is secured inthe middle of the holder 4, and 46 adjacent to itsjouter end and another pin 9 isslidably mounted in slot 1Q'Cl1t in the inner end of blade holder 4 and extending into shank 6. Both'of the pins 8 and 9 are formed with narrow shanks to fitin recesses 11.

cut in the ends of blade 12 which consists'of an obloiig- 50, shaped piece of thin steel with its longer edges sharp:

ened. The tops of pins 8 and 9 have relatively wide heads to engage the top of the blade when in position so as to hold it against the holder 4'. The pin is formed with shoulders 13 to engagethe Specification oi Letters Patent.

7 blade. The pin 8 is then slid along slot 10 so that it slot imthe holder to admit or, the removal and replace ment of" the blades, the slidable pin being provided it 'Justable pin in an adjusted position, substantially as shown- .Patented Oct. ancer;

slot 10 to prevent it from turning and a 5.5" 14, and is held in a locked position by of a thumb nut 15 fitting the threaded shank.

It will be understood from the above "description andan inspection of the drawings that whenthe blade 12 is placed in position the thumb nut lfifmay be 'imgs'o screwed so as to permit the pin 9 to be withdrawn uswards the handle 1. The blade 12 is thenlaid on the holder 4 and slid towards the outer end thereof sothat the 'pin 8 engages the recess 11 in the outei endiof. the

engages the recess 11 in the other end of the blade and after the thumb nut 15. is tiglitened on the threaded. shank 14 the blade is held securely in position. To

remove the blade the above operation is reversed. It will be understood 'also that as my improved razor consists of easily dismemberedparts it is capsble of being thoroughly cleansed with the leastexpenditure of time and trouble, Having thus described my invention what I", claim lB-' 7-75 1. In a safety razor, a blade holder, :1 headed pin rigidly secured to the holder, a headed pin adjustably mounted'on the holder, a blade formed to engage said holder andpln's and means to rigidly secure said adjustable pin in an adjusted position, substantially as shown anddsscl'ibed.
