SAFETY-RAZOR.

insana.

' To all 'whom'it may concern.'

doned on lMay 8, 1910, and of which the fol- A lowing is a full, clear, and exactpspecification.

My invention relates to safety razors of the type wherein the razor may be stropped Without being removed from the razor holder, and it has for its object to provide means whereby a double-edged blade may be used in such razors and bothedges of such blade be stropped, particularly while in the holder. v

A. practicable form of my invention is illustrated in the accompanying drawing, whereinp Figure 1 is a side elevation of a structure made according to my invention. Fig. 2 is an end elevation thereof. Fig. 3 is a view similar toy Fig. 2, enlarged, and illustrating the stropping position of the rhzor in full lines, and in dotted lines its position when raised preparatory to lowering' to such position. Fig. 4 is a vertical crosssection of the device as illustrated in Fig. 3. Fig. 5 is a longitudinal section of the holder and blade and of the slides for carrying the holder, this section lbeing taken on a plane at about the line 5-'5 of Fig. 6, and Fig. 6 is a plan view of the holder and blade and of the slides, the guide rails for the slides being indicated in cross-section.

My raz/or is shown mounted upon a handle 1, and provided with a frame, U-shaped when viewed from the side, and comprising a base-plate `2, to which the handleis attached, and side pieces or arms 3 4, which are connected byV strop-guiding-rol 7 8, and by strop-actuated-roller 9. Shifting

plates

10, 11, are mounted in the sideframes 3, 4, with which they have a vtongue and groove connection, so as to slide-therein. Mounted in such plates so as toshift therewith and also to turn therein freely at the same time, is the rod 12, which carries a gear 13 fixed to it at onev end, which projects through and beyond arm 4. The rod 12 supports a double-edged blade 14 inter- Spccication of Letters, Patent.

mediate the arms 3, 4.- Said blade is shown perforated t6 be received on pins 15 pro- ]ecting upwardly from a blade-receiving platel.. Upon which plate 16 the blade 1s maintamed in position by clamping-plate 17- hinged to the receiving plate at 18. The clamping plate is held closed by springcatch 19.

The sliding-

plates

guards

20,21, as seen in Fig. 2. IIhe razor is held in-such position by catches 22 of springs 23, mounted upon side-frames 3,- 4, which enter perforated ears 24 projecting endwise from the sliding

lates

en it is desired to strop the razor the catches 22 are released, the

plates

raised until the razor-blade 14 clears the guard plate, when it is turned to a position transverse of the plane of the double blade seat afforded by the guards, and lowered until the catches 25 enter the ears 2 4. In.

clockwise movement of roller 9 and sectorv `26, and a clockwise movement of gear 13,

causing the upper edge of the razor 14 to move in the direction of` the dotted arrow- (Fig. 4), and its lower edge to move in the same angular direction, stropping the respective edges by contact with the strop. A reversal `of movement of the strop will cause the above parts to move in the o pposite direction and will strop the other edges, and this motion may be changed rapidly.

WVhile l have here illustrated and described a concrete embodiment of my invention, it may be seen that in many respects the same is illustrative merely, as the invention could be embodied in other and equivalent forms. I conceive that it is broadly new to produce a safety razor emrateateu aan.. a, raie.

, blade may be' stropped Without removal.

Having thus'l described my invention'what I claim is: l

1. A safety4 razor comprising a framefa blade 'carrier and a. double edged .blade adapted to be clamped therein in shaving position, a guard for said blade, means carried by the frame for guiding a strop and means for moving said blade carrier from shaving to stropping position and means for stropping both edges of said bladesimultaneously while carried by said frame.

.2. A safety razor comprising a frame, a double guard, means carried by the frame for positioning astrop, a double-edged blade, a carrier forthe blade provided with slides, the frame being provided with guides for the blade-carrier located for supporting the frame adj acentthe guard or adjacent the strop positioning means,y and means for clamping said blade-carrier in either of said ff positions and the blade in operative position uponsaid guard or in operative position relative to the strop position.

3. A safety razor comprising a frame, strop-holding and positioning devices located on the frame, a double guard located on the frame, a double-edged blade coperative with the guard and with a strop traversingsaid ystrop-holding means, a blade-carrierfand means for shifting the blade carrier to bring the blade into operative position upon said guard and into operative position in respect of said strop and into position for concurrently stropping both edges of said blade while carried by the frame.

4. A safety razor comprising a frame, a double guard, a double edged blade and a movable blade carrier, means for clamping the blade in shaving position upon the guard while in place in said carrier, means for moving said carrier from shaving position to stropping position and from stropping position to shaving position, and means for stropping both edges of said blade simultaneously while in place in said carrier in stropping position.

5. A safety razor comprising a frame, a double guard, a double edged blade and a movable blade carrier, means for clamping the blade upon the guard in shaving position while in place in said carrier, means for holding the blade in posi-tion for stroppin means for simultaneously stropping bot edges of said blade, and means for moving the carrier and blade from the shaving position to the stropping position.

6. Asafety razor comprising a frame, a double guard, a double-edged blade and a movable blade-carrier, means for clamping the blade upon the guard while in place in said carrier, means for stropping said blade, guide-rollers for said stroppin means, a rack connected to one of said ro 1ers,` and a pinion connected to saidblade-carrier and located in position to coperate with said rack when the blade is'brought to stropping position; and means for moving said blade to stropping position.

7. A safety razor comprising a frame having a central recess, a double guard and a double-edged blade adapted to coperate therewith, a movable blade-carrier mounted in a sliding frame, means for clamping said blade in operative position upon said guard, guide rollers adapted to guide a lstropping element, means connecting one of said rollers with the blade carrier for oscillating the same, andmeans located in said recess for stropping said blade while carried by the frame.`

8.. A safety razor comprising a frame having a central recess, a double guard and a double-edged blade adapted to coperate therewith, means for clamping said blade in operative position upon said guard, means located in said recess for stropping said blade while carried by the frame, guide rollers for said stropping means, 'a rack connected to one of said rollers, and a pinion connected to said blade-carrier adapted to cooperate with said rack.

9. A safety razor comprising a frame, a double blade seat, a double-edged blade and a movable blade-carrier mounted in a slide slidable on the frame in a path transversely of the plane of said double blade seat, means for clamping the blade upon the guard while in place in said carrier, means for stropping said blade, guide rollers for said stropping means, and means connecting one of said rollers with the blade-carrier for oscillating the same.

10. In a safety razor, a blade-holder adapted to receive a double-edged blade and expose both its edges, means for clamping the blade in position therein, guards for said blade, rollers for guiding a strop in opposite directions on the razor, means for moving the blade from'shaving to stropping position, and a connection between oneof said rollers and the blade-holder for rocking same as the strop is moved, to simultaneously strop both edges of said blade.

In Witness whereof I have hereunto set my hand in the presence of two subscribing witnesses.
