Referring primarily to. therazor, it will be noted that the reference numeral 20 indicates the handles of these devices, these had dles in the present instance supporting at their upper ends yokes 21 the arms 22of' which have their outer ends extending beyond the handles a distance in excess of the widthof the blade. i

In each form of razor a shaft 23 is rotatably mounted between the upper ends of these arms,

and this shaft, particularly as has been shown in Figs. 15 and 16-, may carry a gear 24: and

' a bladeholder or retaining device. The hit-- teixpreferably includes a body 25 provided with portions 26 extending around and fixed 1y secured to the shaft 23, this body being further extended to provide a tongue 27 formed with an inwardly-struck portion 28 in line with an opening 29 formed in the main portion of the body. The latter is also provided, if desired, with outwardly-struck portions 30, which, when a blade of the character shown in Figs.-14 and 15 is employed, extend into notches 31 formed in the rear edge of this blade and thus prevent'a sidewise displacement of the latter. i

It will furthermore be noted that the blade body 32 is formed with an opening 33, and has its side edges recessed to provide shoulders 34 adjacent its cutting edge, the corners between these side edges and this cutting edge being preferably rounded as at 35.

Thus it will be apparent that the blade is simply grasped and shoved between the body and the tongue 27, in which'position it-is retained incident to the fact that the inwardly-struck portion 28 of the tongue will enter through the opening 33 and extend into the o ening 29, and furthermore, as aforestate for thereason that the extensions will ride within the notches 31.

With reference to the type of razor shown in Figs. 1 to 3it will be observed that the guard is swingingly secured to the yoke or fork 21. This guard conveniently includes a. plate 36 presenting a comb 37 at its outer edge, the teeth of which, as in the usual manner, extend outwardly, the end teeth 38, however, extending inwardly for a purpose here-' inafter brought out. The endsof the plate 36 are extended at right angles to the body thereof, so that a U-shaped member is pro vided. These ends 39 have their: lowermost 1 razor yoke. when the guard is in its normal 3 position, as has been shown in all of the figures referred to.

Withthe shaft '23 in position it will be un-v derstood that, as previously brought out, the blade will be prevented from relative movement with respect thereto, and if the guard is a in the position shown in the figuresreferred 40 to the cutting edge of the blade will lie adjacent the outer ends of the teeth of the comb 37, the shoulders 34 of this blade being engaged by the rearwardly-extending teeth 38 of the comb so that relative movement between these parts is also prevented. It will be, equally obvious, however, that by simplypressing the rear ends of the elements 3.9outwardly the inwardly-struck portions 41-which clear the rear edges of the yoke and the guard may be swung with respect to the handle to a point at which the cutting edge of the blade clears this guard, and the blade body may be freely rotated between the arms of the yoke.

The construction shown in Figs. 4 to 6 is, in *all respects, similar to that shown and described in connection with Figs. 1 to 3, with the exception that instead of the inwardly struck portions 41 one of the arms of the guard is provided with an arcuate slot 42, and the corresponding arm 22 of the razor yoke carries a lock nut 43 mounted upon a screwthreaded shaft 44 and adapted to be tightened so as to bear against the outer face of the fork arm in order to clamp the same into position and prevent relative movement.

Dueto this construction, in additionto the fact that the parts are properly supported and the guard may be freely swung to inoperative position, the position of this-guard may be accurately. adjusted so that the cutting edge of the blade is disposed in exactly the relationship desired to the comb of the-guard.

In Figs. 7, 8 and 9 the handle20 is screw threaded adjacent its upper end as at 45, and a collar 46 ismounted upon these threads and is of a widthslightly less than the length of the threaded portion. The guard is U shaped, but the arms 47 thereof extend a substantial distance beyond the pivots 40, and, in fact, below the base of the yoke 21.

Interposed between the collar 46 and the yoke base is a plate 48, of a length slightly greater than the length of this base and procollar tightened the plate 48 will have its ends firmly bear against the extended portions of the arms 47 in order to prevent relative movement of the blade and guard. However, if the collar is loosened theintimacy of contact between the plate and the arm portions aforementioned will be reduced, and, consequently, the guard may be adjusted, or the guard may be moved to wholly inoperative position so that the blade may be swung in the manner aforedescribed. I

Thus, in the constructions shown in Figs. 4

to 9" inclusive, it is not alone practicable to normally retain the guard against movement and to move the same to a position at which the blademay be swung through the fork or yoke, but, also, the position of the guard may be adjusted to relatively project or retract the cuttingedge of the blade to any desired position. However, itis obvious that various'forms of mechanism might be employed to advantage in order to accomplish-this result.

In the form of razor shown in Figs. 10 to 13 inclusive, the guard is provided by utilizing a guard-plate 50 having a comb 51 at its outer edge, the end teeth of this comb extend; ing inwardly as at 52. The plate 50 is continued in the form of a shank 53 extending downwardly and terminating in a handle 54, its central portion extending inwardly as at 55 and across the upper en'd'of the handle 20. At this point it is pivotally secured to the handle by means of a pin 56', which also extends. through a second .downwardlyand inwardly-extending portion 57 forming a part of the plate.

Normally, the guard is retained in the position shown in Figs. 11, 12 and 13 by means of a collar 58 slidably mounted upon the handle 20 and of an inner diameter sufficient to accommodate the handle 54 and prevent move ment of the same with respect to the firstnamed handle. However, if desired, the collar 58 maybe swung downwardly, as in Fig.

ed upon this strop is a traveler including til-shaped plate 60, the body of which extends below the strop, and the arms adjacent the side edges thereof and above the upper surface of the same. In order to retain the traveler in this position, and also to antifrictionally guide the same, a pair of rollers 61 extends between its arms and bears against the lower strop face, while a further roller 62 bears against the upper face of the strop and lies in a position between the rollers 61. The upper arm ends of the traveler are preferably notched as at '63 was to accommodate the ends of the shaft 23; and it will be obvious that with the shaft in this position sidewise movement of the razor with respect to the traveler will be prevented, and that if one of these elements is moved the other will move in unison therewith. Also, if the gear 2% is associated with the shaft 23, and a gear 64: is associated with the shaft of the rollers 62, these gears will mesh so that any tendency of the roller 64 to turn will be transmitted to the shaft 23.

Thus it will be apparent that if the guard. of a razor is swung to inoperative position,

and the shaft thereof is moved to a point at which its ends extend into the notches 63, any subsequent movement impartedvto the traveler, as, for example, by exerting a pushing and pulling action upon the handle 20 of the razor, Will necessarily result in these elements traveling as one unit and in the roller 62 tending to turn. The direction of this turn ing tendency will vary according to the direction in which the traveler is moved, but, in

a any event, it will be appreciated that due to the fact that the shaft 23 and the shaft of the roller 62 are coupled, as, for example, by the gears 24 and (it, the shaft of the razor will be turned to a point at which the cutting edge of the blade will bear against the upper surface of the strop and will feather over the same, Obviously, a small number ofmovernents on the part of the traveler and razor will resuit in the blade being excellently sharpened t sarily be held taut by and conditioned, and

virtue of the fact that the edge of the blade will bear against the 1e strop need not neces- If desired, and as has been illustrated in Fig. 19, in lieu of a strop such as has been previously described a rigidsupport 69 may be employed, This support may, if desired, form the top or body of the box in which the razor is sold, and may have its opposite faces covered by strips 70 and 71 presenting, for example, honing and shopping surfaces, respectively. Travelers, generally indicated at 72, may be mounted upon'the support 69 so that the razor may be applied with facility to either of the strips 70, 71.

Finally, if it is desired to present a turning of the blade when the guard is in inoperative position, the desired result may be accomplished,as has,for example,been illustrated in Figs. 20 and 21, by simply associating a spring 73 With the razor yoke and bearing against the blade-supporting shaft. Obviously, the frictional contact between this, spring and shaft will prevent a turning of the latter, but

upon the razor being applied to the stropping device this will in no wise interfere with the proper operation of the parts.

' In all of the forms of razors illustrated it will be apparent that a user may readily employ the razor to advantage, and that the portions of the face which are relatively inaccessible in using the'ordinary type of razor may be readily reached by any of the devices as herein illustrated, in that the entire length of comb will be covered by the cutting edge of the blade, Furthermore, due to the fact that the corners of the latter are rounded, but little danger will exist of a person accidentally inflicting a cut, and this will further be guarded against by virtue of the rigid manner in which the blade is normally secured against movement with respect to the razor parts.

When desired, the guard is readily movable to inoperative position, and the razor may be applied with facility to the stropper, which, by means of the razor handle, may be manipulated back and forth over the sharpening surface in order to properly condition the blade; and immediately upon the sharpening operation being completed the parts may be swung to their normal position and the razor will again be ready for use,

Thus, among others, the objects aforementioned are accomplished, and since certain changes may be made in the above construction, and difierent embodiments of the invention could be made, without departing from the scope thereof, it is intended that allmatter contained. in the above description, br shown in the accompanying drawings, shall be interpreted as illustrative and not in a limiting sense.

Tt is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which as a matter of language might be said to fall therebetween,
