rier inthe chamber, the blade will be sharpened.

Another object oi the invention is to provide the. razor with la `handle and blade carrier `of such construction and dimensions that a blade of proper size to fit the guard of the razor may i be applied vto the carrier and the carrier and blade'then thrust into the handle as a unit and allowed to remain therein until use of the razor is required. By lthis arrangement, the blade will always be readily Vaccessible when needed `and can be sharpened before use.

Still another object of the invention is to so form the handle and blade carrier that when the carrier is thrust into the chamber oi.' the handle, it may be oscillated to dispose the cutting edge of the blade in proper angular relation to a block of abrading material in the chamber and to limit the oscillating movement of the Vcarrier and 'also 'guide longitudinal movement of the carrier during reciprocation thereof whenl sharpening the blade.

A still further object of the invention is to so construct the carrier that when a blade is applied thereto, it'will be firmly held in its proper position and caused to move with the carrier. The invention is illustrated in the accompanying drawings wherein:

This improved razor has a handle I formed with la reduced neck 2 at its front end, the `extreme forward end of which is further reduce'd to provide a rivet l by means of which a guard or shield `4 is rigidly secured to the handle. The shield isformed of sheet metal and has ifsfupper portion 5 curved rearwardly and downwardly and terminating in a tongue 8 llocated intermediate 'the width of the shield and formed with an opening through which the rivet!V is passed and then headed as shown in Figure 3. The shield or 'guardjis disposed transversely of the handle and has Vits lower edge portion formed with4 teeth 1 through which portions of the cutting edge of a blade 8 will be exposed when the blade is applied againstI the 'outer `or front face of the shield. `'Ihere have also been provided spurs or tongues 9 located adjacent opposite ends of the lower edge of the shield for engaging Aunder thev cutting edge of the blade and supporting the blade when in place. g

The blade is to be securely-but detachably held in engagement with the shield and in order to "do so there has beenprovided a bar lll formed froma strip of resilient metal. This bar has tongues which are bent to form loops Ill engaged through slots I2 formed inthe shield and serving to pivotally mount the bar, for swinging movement from the released position shown in Figure 6 to a clamping position in which it extends across a -blade alongfthe backing :la at one end provided with longitudinally extending the upper edge thereof. The free end portion. of the bar is bent to form abill Il which snaps over the edge of the shield as clearly shown in Figure 4 and securely but releasably holds the barin the clamping position. By this arrangement, the blade can be quickly applied to the shield and firmly secured.

Referring to Figures 3, 5 and '1, it will be seen that the blade is narrow and that when it is applied against-the guard, the backing 8a is disposed midway the depth of a slot la formed longitudinally in the guard. It should also be` noted that the backing holds the blade in spaced relation to the front face of the guard to provide a space I3 between the blade and guard extending from the lower cutting edge of the blade to the slot. Therefore, lather and hair which may be forced between the guard and lower edge of the blade during a shaving operation may pass upwardly through the space I3 and out through the slot 4a without choking the razor and preventing the bladegfrom cutting properly. By bowing inwardlythe lower portion of the guard, the size of the space I3 will be increased and free passage of the lather and hair permitted.'

When the blade is to be removed it is merely necessary to spring the latch out of engagement with the shield and the blade can be removed and the razor and blade thoroughly washed.

The handle I which is also formed of metal is hollow to provide a chamber I5 opening through the rear end of the handle and by referring to Figures 12 and 1 3, it lwill be seen that the handle is elliptical in cross section and has its walls crimped inwardly to provide sets of ribs I6 and I1, the ribs of-each set being spaced from each other circumferentially of the handle. An elongated blockr I8 of honing material extends longitudinally inthe chamber I5 and is cemented against walls of the chamber between the ribs I6 which engage opposite side edges of the block and prevent the block from shifting transversely out of its proper position. 'I'his block is formed with a groove I9 in its exposed face and referring to Figures 12 and 13, it will be seen that walls of the groove are curved transversely and oonverge inwardly of the groove in order that the bevelled faces of the blade-along its cutting edge may have proper engagement with the abrading block during a sharpening operation.- l In order to suppOrt the blade in the chamber and impart reciprocating motion to the bladeK during a sharpening operation there has been provided a blade carrier which is formed of resilient metal. carrier is of tubular formation and at its rear or outer end carries a head or ilnger hold 2| which has its marginal face roughened in order that it may be rmly grasped and is provided with a neck 22 of the proper shape and dimensions to fit snugly within the rear portion of the handle and have frictional gripping engagement with walls of the` handle to securely but removably hold the carrier in the chamber of the handle. The tubularrbody is not circular in cross section but of the conflguration shown in Figures 12 and 13 and has an arcuate wall 23 which conforms to'the portion of the walls of the handle between the ribs I1 and merges into side walls 2l which are bowed inwardly. A partition or abutment wall 25 blocks the interior of the body intermediate the length thereof and between this partition and its open forward end the body is formed with a longitudinally extending slot 26. The portions of the side walls bordering the slot carry extensions which project inwardly of the tubular body and form grip- The bodyv portion 20 of the bladel -brought into engagement with the abrading ping jaws 21 the lower edges 2l of which diverge and bear against portions of the backing strip la at opposite sides of the blade 8 when the blade is thrust into the holder. When the blade is thrust into place, it is forced inwardly between 5 the Jaws from the front end of the body and as it moves rearwardly, it passes between tongues 29 at the front of the body. These tongues extend longitudinally of the body at opposite sides of the slot and have their free endsnormally in 10 engagement with each other so that when the blade is in place, the front ends of the tongues will engage each other beyond the outer end of the blade as shown in Figure 10 and prevent the blade from slipping forwardly out of place. 'I'he l5 abutment wall 25 prevents the blade from shifting rearwardly of the carrier beyond the position shown in Figure9 and therefore, the blade will be caused to reciprocate with the carrier during a sharpening operation. Tongues 30 which are struck from the wall 23 of the carrier and extend longitudinally of the carrier engage the backing strip of the blade and hold the blade in its proper position with the backing strip bearing against the flared portions of the jaws and 25 the cutting edge of the blade in engagement with the abrading block.

When this razor is in use the blade is applied to the outer or front face of the guard where it is secured by the bar I0. 'I'he lower cutting edge 30 of the blade rests at its ends upon the prongs or tongues 9 and between these prongs is overlapped by the teeth 1 as shown in Figure 7 so that there will be no danger of a person cutting his face while shaving. After the shaving op- 35 eration has been completed, the bar I0 is released and swung out of the way and the razor thoroughly cleaned. 4 The blade can then be again secured against the guard but it is preferred to withdraw the blade carrier from the handle and 40. ilt thelblade into the tubular body of the carrier. The carrier is then returnedv to its initial position within the handle and the blade will be shielded and prevented from being accidentally ed. when the razor is again to be used, the 45 carrier is grasped by its head 2| and drawn outwardly. After the carrier has,v been Withdrawn a suiiicient distance to free the neck 22 from the handle, the carrier can be given4 a partial rotation in either direction until the carrier abuts 50 one of the ribs I'I and the carrier slid longitudinally with the bevelled face at one side of the cutting edge of the blade bearing against one of the sloping walls of the recess I9 of the abrading block. A number of' strokes may be imparted to the carrier and the carrier then rotated to move it into engagement with the other rib Il so that the other bevelled face of the blade will be block or a rotary movement imparted to the car- 60 rier at the termination of each reciprocatory movement by turning the wrist before again imparting longitudinal movement to the carrier. 'I'he angular relation of the ribs Il to the'groove I9 insures fiat contacting engagement of the bevelled faces of the blade with the walls of the groove I9 and therefore, the cutting edge of the blade will be properly sharpened. Since contact of the ared portions 28 with the backing l70 strip of the blade limits upward movement of the blade through the slot 26 there will be no danger of the cutting edge of the blade being dulled by improper contact with the abrading block.

the blade is sharpened, as it is withdrawn from 75 tionioi-ounlimproved device, theiloperation thereof--anditheimethod-of applying thefsame to use win-be .readily xunderstood. :'Itxwill.` bereeen that welhave provided alsimple, inexpensivel and emclent means for carrying out the objects of the invention 1 andy while `we @have L particularly described lthe` elements the functions set forth,it is obviousrthat various changes ain i form, AproportionV `and-'inv the -minor best. adapted Y to perform details ofconstructionmay be resorted to,withvoutdeparting from? the spirit orisacriilcing anyV of the principles of the invention.` l l v thus l described'vthevinvention, what is claiinedfisr`4 1' ..1 c i i `:in a razor,"afhan`dle formed with a chamber f opening fthrough the end ofthe handle, a
