Be it known that I, JOHN W.-MoAUmr'rE, a citizen of the United States, residing at -townof Pelham, county of .Westchester,

State of New York, have invented a certain new and useful Improvement in Safety Razors and Stropper's', and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had section through to the accompanying drawings, which form a part of this specification.

My invention has for its object to produce arsimple and novel safety razor, especially one adapted for a double-edged blade, so

constructed and arranged that the blade can t.

conveniently be. stropped without removin it.

he various features of noveltywherebv my invention is characterized-will herelnafter be pointed out with particularity in the claims; but, for a full understanding of my invention and of its object and advantages,

reference may be had to the following de-v tailed description takenin connection with the accompanying drawings, wherein:

Figure l is a vertical section through a razor arranged in accordance with my invention, the section beingtaken on a plane containing the axis of the handle and the longitudinal central axis of the blade;

' Fig. 2 is a section taken on line 22 of Fig. 1;

Fig. 3 is a section taken approximately on line 33 of Fig. 2';

Fig. 4 is a top plan .view 'of the lower blade-clamping bar;

Fig. 5 is a top plan view of the upper blade-clamping bar; a

Fig. 6 is a bottom plan view oftheupper holding or gripping plate;

Fig. 7 's a top plan view ofa stropping' device adapted to be used in stropping the o p Fig. 8 is a side elevation of the shopping device;

Fig. 9 is anend elevation of the stropping device, only a fragment of the device being shown; and p 1 I Fig. 10 is a viewconsisting of a vertical end elevation of the razor occupying a stroppingposition in the device.

Referring to the drawmgs, 1 represents a handle. of-any usual or suitable construe limiting the movement of the 'bar length;, ;.80

.ing hub-or-sleeve, the handle. 'Theguard is provided with openings, 17,. through which the guiding f the stropping device and an tion on the upper end of which a razor blade 1s adapted to be supported. In thearrangement shown, vthe blade is adapted to be clamped between two bars, 2-and 3, hinged 6 together at one end by a suitable hinge of which the parts on the'r'espec'tive barsare indicated at 4xand 5; the blade being adapted to be laid upon the bar 2, thebar 3 being then swung downwardly on top of the blade 65 and locked in. place by means of a suitable catchjdevice between the free ends of the bars, such a device being indicatedat 6. The middle portion ofthe bar '2 may be pressed downwardly as indicated atj7, the 7i) cup thus formed beingprovided in the bottom thereof, at the center, with an opening,

-8, through which the upper end of the handle, projects. A nut, 9, on 'theulpper end of' the hand1e, h0used within the depression, 7

serves to hold the blade-holding bar 2. upon the handle, the upper end of the handle being pieferably reduced somewhat in diam} shown; the nut and the shoulder wise of the handle, but permitting it to turn on the handle.'- .The blade, which is indicated at 11, is properl aligned by means of pins, 12, screw threa ed intoope'nings, 13,- d to 8 near the ends of the bar 2 and adapte project through properly located openings in the blade through openings, 14, in the upperclampingbar. The pins, 12, are made long so as to project downwardly a considf erable distance from the lower clam in'g'90' bar and serve as uides for a guard 'p ate, 15, which lies umfiarneath the bar' 2and is provided with a' long; downwardly-proj ect- 1'6,-screw threaded upon pins, 12, extend'.

The holding bars 2 and 3 are made quite narrow so as to leave wide marginal portions of the blade free when ablade is clamped in place and it is for that reason that the additional I plate being adapted tobe moved along the guard plate is employed, thefguard handle away from the blade when it is desired to strop the latter. It is -also desirable to have an upper clamping orholdingplate wider than the'plate 3-, to engage the top 0 the blade'while the latter-is be1n used for shaving. have therefore I 1 paratively wide top' plate, .18, having on the;

provi ed a comunder side a central post, 19, adapted to be' Screweddowninto the'upper'end of the hair. f

dle. The plate, 18, is also preferably provided with seats or depressions, '20, 'to receive the upper ends of the pins 12 when the plate 18 is in the position in which it engages the razor blade; the pins 12 therefore serving to center or align the plate 18 with the blade and the guard. The guard plate and also the top plate 18 are properly grooved or chambered in their upper and lower faces, respectively, to form a housing in which the two hinge clamping bars are nested when the plates 15 and 18 are closed on the blade. I

The screw threaded connections of the handle with the. guard plate and the top plate 18 are oppositely disposed so that if the screw threads, 21, between the handle and the hub of the guard plate are left hand threads, those on the post 19 will be right hand threads. Consequently it is only necessary to turn the handle while what may be termed the head of the razor is being held stationary, in order to cause the plates 15 and 18 either to move away from each other and from the blade or toward each other and into operative relation to the blade. Thus in Figs. 1 and 2 these two members are shown closed upon the the blade, namely in their shaving positions, while in Fig. 10 they are shown separated from each other, thus leaving the blade free to be stropped. It will be seen that when the parts are in the positions shown in Figs. 2 and 3, it is only necessary to turn the handle relatively to the holding or clamping plates in order to bring the part-s into the positions shown in Fig. 10 while, upon turning the handle in the opposite direction, the parts are shifted from the positions which they occupy in Fig. 10 to those which they occupy.

in Figs. 1 and 2.

When the razor has been placed in a stropping condition, namely with the guard plate and the upper holding plate spread apart as shown in Fig. 10, it may conveniently be stropped with a device such as illustrated in "Figs. 7 to 10 inclusive. Referring to these figures, 25 represents a rectangular box open at the top and having therein two parallel mutilated stropping rollers, 26 and 27; there being'in the bottom of the box a central openin'g728, large enough to permit the passage of the hub or sleeve, 16, on the guard plate, together with slots, 29, extendmg in opposite directions from the hole 28,

parallel with the axes of the stropping rollers, and wide enough to receive the lower ends of the guide pins 12. The parts are so proportioned" that when the razor, after having been placed in a stropping condition, is dropped, handle first, into the stropping box, the sleeve or hub on the guard plate and the guide pins serve properly to position and align the razor so as to bring the blade into operative stropping relation to the rollers 26 and 27. These rollers are then oscillated simultaneously in opposite direcproper direction, is returned to the conditions shown in Figs. 1 and 2.

The stropping rollers may any suitable manner. In the arrangement shown, each of the rollers has on one end thereof a gear wheel, 30, meshing with an intermediate idle wheel, 31. On the extreme end of one of the rollers or of the shaft, 32, on which it is mounted, is a pinion, 33, lying on the exterior of the box or casing. Meshing with this pinion is a rack bar, 34, slidably mounted on the box or casing in any suitable way, and provided with a handle, 35, for moving it.back and forth. The movement of the rack bar is preferably limited in some way so that it can travel only far enough in either direction to give approximately one complete turn to each of the rollers. In the arrangement shown, the rack bar is provided with a pin, 36, extending through a slot, 37, in a guide plate, 38, for the rack bar; the travel of the rack in both directionsbeing controlled by the pin and slot.
