SAFETY RAZOR Filed Oct. 14, 1930 [LJLj/ULJLILJUULJLJ'I Patented Oct. 3, 1933 UNITED STATES PATENT' OFFICE 1,928386 SAFETY lulzon John D. Garretson, Oakland, Calif. Application October 14, 1930. VSerial No. 488,597

7 Claims. (Cl. 30`-12) This invention relates to a safety razor.

It is well known in'vconnection with safety razors that most of the same V include a head provided with a blade seat and clamping member between which elements the blade is interposed. A suitable handle is provided in association with the head and suitable means is also provided for retaining the whole in applied position. f The primary object of this invention is to provide a safety razor, the parts of which can be cleaned without necessitating the `disassembly of all of the parts of the razor, and without the removal of the clamping member, the blade, and handle.

Another object of the invention is the provision of a safety razor the clamping member or holder of which may be fixedly held inispaced relation* above the razor seat to allow the cleaning of the parts without removing the clamping member or the blade, theV clamping member being also supported so as to allow the turning of the same into an inverted position to permit the replacement of the razor blade, without disassembly of the entire safety razor. i

Y Other objects and advantages are to provide a safety razor that will be superior in point of i simplicity, inexpensiveness of construction, posivenience in use and general efliciency. p In this specification and the annexed drawing, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in-other forms; and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied. t

The invention' is clearly illustrated in the accompanyingv drawing wherein,

Fig. 1 is a sectional view of a safety razor constructed in accordance with my invention.

Fig. 2 is a top plan view of the safety razor.

Fig. 3 is a side view of the safety razor, part of the handle being broken away.

`seatv8. It is to be noted that the bars 14 are outtiveness of operation, andifacility and conlA safetyrazor constructed in accordance with my invention includes a head 6 and a handle 7.

The head 6 includes a substantially concavoconvex blade seat 8 from the center of which the handle 7 extends and upon the convex, upper side of which a razor blade 9 is positioned. As in the Conventional construction of safety razors, the side edges of the blade seat 8 are provided with serrations or' teeth 11. A clamping member 12 fits over the convex side of the blade seat 8 to hold 'the razor blade 9 in place.

Adjacent the opposite ends of the blade seat 8 are apertures- 13 Vinto which slidably fit guide bars 14. The clamping member has a boss 16 extended Yfrom each end thereof. The bosses 16 are in alignment with each other and are disposed in continuation of the longitudinal center line or axis of the clamping member 12. From each boss 16 extends-a pivot pin 17 journaled in the upper end of the adjacent guide bar 14. In this manner the clamping member 12`isjournaled in the upper ends of the guide bars 14 and is held by the latter in alignment with the convex face of the blade side of the' end ofthe blade 9 and do not extend therethrough, thereby to allow the movement of the blade' 9 with the clamping member 12 as the ,latter is turned around its longitudinal axis into inverted position.

l The handle 7 is hollow and it exten'ds from the Y convex surface of Vthe blade seat 8 through the seat 8 and beyond the concave face of the seat, as

shown. Inside of the hollow handle 7 is rotatably disposed a tube 18. The free end of the handle 'I is reduced at 19, and the extremity of the reduced handle end :19 is exteriorly threaded to receive an interiorly threaded bushing 21 thereon. The bushing is spaced from the shoulder 22 of the reduced end 19 to form a retaining groove thereat.` The free end of the tube 18 is enlarged at 23 and it abuts against the end 19 and against the bushing 21. A retaining bushing 24 surrounds the entire head 23 and extends into the groove between the bushing 21 and the shoulder 22. The retaining bushing 24 is fixed to the tube head 23 by means of set screws 26. In this manner the tube 18 is heldj against axial movement in the handle 7 with freedom of rotary movement.

, The inner end of the tube 18 is interiorly threadedV and it abuts against a shoulder 27 within the handle 7. A threaded stem 28 extends from the center of the clamping member 12 into engagement with the inner end of the tube 18. The stem 28 is slidable through the end of the handle 7. By rotating the bushing 24 the tube 18 is rotated. Inasmuch as the stem 28 is held against rotation by the clamping member 12, it is advanced axially by the rotating tube 18. Thus the clamping member 12 can be elevated and held in spaced relation above the convex face of the seat 8, whereby the cleaning of the safety razor is permitted without disassembling the safety razor. On the other hand, by turning the tube 18 in a direction opposite to the .first mentioned turning, 1 the clamping member v1.2 is brought closer to the seat 8 to clamp the blade 9 in place. If it is desired to replace the blade 9 thenthe tube 18 is turned until the stem 28 is entirely disengaged from the threaded end thereof, thereby permitting the turning of the clamping member 12 into inverted position as shown :in-..1158.35 The blade 9 is thus readily accessible and removable from the upwardly projectmg'stem 28' and'a new blade can be placed in position.

In order to prevent the entire removal of the guidebars mirom:theseat8,11;4 stop.29 threadedlyv secured on the .free :end of each bar 14 to abut against :thelower face .of 'the seat 8 -thereby limiting .the upward movement .of the clamping memberV 12 only to .adistance suffi'cient Lto allow the stem. 28 to -clear the' seat :8.1asthe member 12 is turned into. invertedtposition; s

Thusin this safety'razor, a 'razor blade maybe replaced withoutentirely separating .the elements of thetsafety razorfrom each-other.

The blade 9 itself vis'formed w'itha lug Ior `grip Wing 31 .at each end thereof,.each extendingfrom a half of the length of the said end, -whereby the gripping and handling of the *blade -9 .is greatly facilitated.l .The wings 31 extend beyond the .ends of theclarnping member-12 and the latteris to be turned sothat .thewingless Vhalf of Vthe-blade 9 is moved betweentheguide bars Vlflfgnamely, the clamping memberglzis turned .in the direction of its edge denoted -bxzithe numeral 132, when inverted, and it is rotatedinthe direction of its edge 33 When' it is .turned back .to.:norma1position.
