COMBINED SAFETY 'RAZUR AND STBLOPPEE.

To all whom t may concern.'

Be it known that l, WILLIAM H.. Lrsrr, a citizen of the -United States of erica, and a resident of York, county of York, and State of Pennsylvania, have yinvented certain new and useful Improvements in Combined Safety Razors and Stroppers, oi' which the following is a full and clear specilication. 4

'lhis invention has relation to that type of combined razor and stropper in which the blade is released from the guard and alholder during the stropping operation, the stropper being on the order of the well-known oscillating-` blade type, forth.

In the drawing- Fig. 1 is a vertical sectional view of my device adjusted for use as a stropper;

Fig. 2 is a vertical sectional View taken at right-angles to Fig. 1;

Figs. 3 to 8, inclusive, are detail views hereinafter more fully described.

Referring to the one sheet of drawing annexed, 10 is a handle attached to the upper end of which is a cross-bar 11 of al frame, the frame having upstanding sideplatesl 12, this frame being desirably made of a single sheet of metal, as shown in Fig. Ll,

as more fully hereinafter set which is stamped up to bring the :frameplates 12 at right-angles to thebar l11. yAt the bottom corners of the'side-plates, outward depressions 13 are formed therein to provide sockets for the ends of rollers 14 which, together with a central roller 15, form the guide for the strop 16.

Journaled in the upper part of the frame, with its axis in the same vertical plane with the axis of roller 15, is a hollowroller 17, one end of which is journaled on an inwardly-extending boss 18 on one of the sideframes and the other end of which is journaled, through the medium of a plug 19, upon pivot-rod 20 connecting the side-plates 12 of the frame, said plug 19 being inserted tightly in the end o' the hollow shaft 17 and being provided with a gear-Wheel 2l which lies in an outward depression in the adjacent side-frame 12. This gear 21 is adapted to mesh with a gear- 22 affixed to the shaft 23 of the under roller 15, this latter gear 22 being, like gear 21, housed in a depression 24 formed lin the side-plate 12, whereby the two gears are located entirely out of the path of the strop andare protected against injury.

'lhe ends of the shaft 23 are journaled in cup-like depressions 25 formed in the sideplates 12, these journal cups being elongated vertically so as to permit the rollerl 15 to have a free body movement toward and from the upper roller 17, the extent of this movement being sucient to permit roller 15 to drop away iar enough to demesh the gears when there is no pressure on the roller 14: from the strop. rlhe roller 15 is desirably made or' aluminum, to thereby avoid glazing the4 surface of the strop,-and, to still further guard against glazing, l prefer to provide the face of this roller with one longitudinal groove 26 which will present to the face of the strop longitudinal edges which, when kthe roller 15 is held a ainst rotation in the stropping action, will s ightly scrape the surface of the strop. Any number of these grooves 26 may be employed; -I believe that two Will be ample.v It will be understood that these grooves 26 will come into operation only occasionally, i. e., whenever the two gears are brought into mesh in such manner as to bring one of the grooves 26 at the under side of the roller at the time when `said rollers cease' to rotate and the strop is sliding under the roller. It will be understood that there need be no yattempt on the part of the user to adjust the roller 15 so as to bring the scraping-edges into action, as these edges need not be brought into action every time the stropperis used, it being suilicient' that they come into use a certain percentage o, times in .the course of use of the stropper; for instance, l believe that yunder the laws of chance one 'of these scraping grooves will come into use about on an average of once in every 24 times the stropper is operated, and I figure that .that will be amplysuiiicient to prevent glazing the surface of the strop in viewof the fact that it is obvi- ,ous that glazing can be prevented b an occasional scraping or roughening oi the surface of the strop.

The hollow roller 17 is provided with any suitable form of blade-holding means. In the present instance, I show a pair of sheetmetal clamping-plates 27 which are desirably formedl integral with the hollow cylinder 17, these plates being connected together near their junction with the cylinder by one or more rivets 28, the plates being, of course, resilient. The shaving-blade 29 is held between the plates 27. This blade isprovided at each end with an inwardly-extending notch 30 having a Veshaped mouth 31. lhese slots 30-31 are adapted to engage a pair of spring-actuated lock-lugs 32 ycarried by one of the plates 27 and extending throughl registering slots in' the opposite plate, these lock-lugs 32 being Vshaped. In Fig. 6 I show these lugs as being carried by spring-arms 33 riveted to the exterior of the bottom-plate 27 ,Y the V-shaped lugs 32 extending upwardly rthrough the slots in said plates, across the .space between the plates and in such position as to be engaged by the slots 30-31` in the blade when the blade is pushed endwisely into the space between the plates 27. These arms 33 are desirably connected together by a bar 34 and are secured in place by the aforesaid rivets 28. In Figs 8 I show a slight modification; in this form, the spring-arms 33 are formed by slitting the under-plate 27. With this construction, itwill be seen that when the shaving-blade is shoved end-wisely into thel holder, the inner end wall of the notch 3() will strike against the beveled edge of the nearest locklug 32 and cam the same far enough upward'- ly to permit the blade to pass; then, when the notch 30 at the far end of the shavingblade engages the lock-lug 32 at the opposite side, the previously-raised lock-lug will drop into the nearslot 30 and thus lock the blade against movement in any direction while in the holder. The blade may be removed by forcibly pulling it endwisely in either direction. The stropper operates in the usual When the strop is inserted through the system of guide-rollers, the driving-roller 15 will have its gear 22 forced up into mesh with the companion gear 21 and then, as the stropper is pulled back and forth on the strop, the gearing will cause the blade-holder to flop from one side to the other, the driving-roller' 15 being held against rotation after the edge of the blade comes against the strop, as usual. To assist in guiding the end of the strop between the guide-rollers when it is interlaced therein, I provide a dished plate 35 which is fastened on the upper side of the bar 11 and has its side edges extending outwardly and upwardly in opposite dircctions to points near the freely-rotatable guide-rollers 14.

I mount on the upper end of the handle, just below theframe-ba'r 11, a guard-plate 36 which at its outer edge is provided with the usual down-turned iin ers 37, and, at the side edgesof the guar p1ate, with upturned hooks 38. I rovide means for raising and lowering t is guard-plate on the handle, and, to reventv it rotating on the handle, I make t e upper end of the handle ybe prevented from rotating thereon.

whereby the guard-,plate may be freely moved up and down on vthe handle but will A sleeve 40 is mounted on.' the handle and threaded internally to engage threads on the handle, for the purpose of raising and lowering theguard-plate, an outwardly-extend ing annular flange 41 being provided at the upper end of the sleeve for enagaging integral depending lugs 42 on the guard-plate, lugs 42 being in the form of hooks to engage under the annular flange 41, so that the retraction of the sleeve 40 will forcibly pull the guard-plate down so as to be out of the way during the stropping operation. The parts are so proportioned that. when the guard-plate is dropped down to the position shown in full lines in Fig. 1 and the strop is removed from the stropper, the edge of the blade 29 will rest on the upper face of the guard-plate at a point a short distance behind the hooks 38; then, when the guardplate is pushed up to the position shown in dotted lines in Fig. 1, the edge of the blade 29 will slide along the upper face of the guard-plate and automatically engage behind the hooks 38 and thus lock the blade to the guard.

VThe stropping devices herein described and illustrated are covered by my co-pending application Serial No. 561,365.

I do not desire to be understood as limiting myself to the precise details of construction and arrangement shown, as variations and modifications therefrom may be made without departing from the spirit and scope of my `invention and improvements. I
