To aZZ whom; itfmayoof'werm' fr Y Be it known that I, MARCUS H. RHODES, a citizen of the United Stateaand resident of the cityof St. Louis and State of Missouri, have invented a certain lnewand useful Improvementin Razor-.Stropping Devices, ofivhichfthe following is agspecification.

Myinvention relates to devices for stropping safety razor blades andv has for its principal objects to produce asimple and eilicient device that isjcompactand easily operated bypersons having no' particular skill., Other..objects are Vtol provide means for reversing the blade so that-it may be sharpened on both sides, to prevent the blade from striking the stropping member forcibly reversingthe blade fromftime tdtime so 8 8 ofirig. 1.

Vis madefof leathei'erfof otberLjsuit#V that both sides thereof may be sharpened. The invention further consists in the parts and combinations Aof 4parts hereinafter described and claimed. i

in the drawings which fom parte of this specification and wherein like reference characters indicate like parts Wherever they occur, n t

Gis a fragmentary sectional-view of the st'ropping member;v f `Fig. f7 is a sectional view: along the line Ay stropl member` 9 that. is preferablycire able f material Avvith 'alternating praised i arid i depressed portions inthe surface-.as indi#` cated in Fig. 6 is mounted one .disk 10.

Y The strop 9 and disk 10 are jmountedina housing comprising a base 11 andV a cover 112 WhoseV respective sides are` secured together in` any suitable manner as by crimping the sides of the'cover 12y around the base 11.

VThe coveris provided Withan `opening -K13 permitting a razor blade to contactfvvith.the'V strop'l 9 as will be hereinafter. described.

Secured at the'center of the strop, 9 i's a.

tubular lstandard 14 which passes through an opening 15 in the cover 12. AY plate 16 that is adapted to support the operating mechanismlis provided Withan opening 17V by which itis mounted onthe standard '141J i A Washer 18 'is mounted on the standard 14 between theV cover 12 and the .mechanism supportl.V A pinion 1 9 is mounted onthe standard 14' just aboveA lthe mechanism support 16. A handle 20. is hingedly secured to a shaft 22 as indicated` at 23.l The handle 'i j20" is provided with a Vsuitable linger support 24. The 'shaft22is mountedin the standard 14 --and is provided atl the' lowver-v end' vvith a. clutchV 25-l comp-risingl teeth formed-'on the bottomithereofand in the bottom of the standard 14. Thus, asv the handle 2O is rotated` vin one direction kthe teeth V vofY the clutch. V25v will engage each other, andthe strop 9 Yand the piniond 19 vvill bejrotated. If the handle is Yturned inthe other direction the teeth Will not Ve'nz'gage and the' parts will not rotate. The hinged connection between vthevhandle 2O and the Vshaft 22 permits the handle to be folded outVv of Vthe Way when the device is not in use'. Y.

A'bifurcated blade *holder 26 comprises jaws 27forming a clamp between` Which a blade may be held. A rivet 28 or the like j may be providedto holdthe two members of'- the blade holder 26 together. p holderv26 is mounted at oneiend offa shaft 29'. which .shaft is providedfat its other end Said blade." :10o

Withapairf ofoppositely disposed cams or lugsfBO andav'itha pinion 31.`'. Tlie methodl ofsu'pporting said shaft'29l and the bladeV holder 26 isy describedhereinafter.` l

-The'mechanism support'y 16 is :provided with standards B2 and vSwvhich are prefera'blylaunchedoutfofV saidsupport and;4v f

bjent AVu pvliard therefrom. Said standard V32V has a 'circular hole 34 neariits'outerfend and` the standard 33 hasia iongtudinaislot 35: Y .Y extending from its'outerl end. Ashaftj f I is provided with reduced endportions which are journaledfin the hole and the slotr 35, respectively. Said shaft 36 constitutes a support for the blade holder 26. and its snpporting shaft29. .Preferably the shaft 1:56 has .arectangular portion 87 nearjthestand ard and a circular portion 38 near theV Vstandard 323.V l ln the circular portion 38 or the shaft 36 is a circumferential groove 39 whose function isexplained -hereinafter.-

i The shaft 36 is provided with a transverse hole'in which ismounted a tube 40. The shaft 29 of the'blade holder extends through said tube 46" and-is treeto turn therein. Thus, as the shaft 36 is rocked or lrotated the'blade holder 26 is moved towa-rdor y away frointhe strop 9and.y as the shaft 29 'The shuttle yisrotated the position of the blade relative Vto the strop may be reversed and the face of the blade that was away Vfrom the strop be brought in contact therewith.

Rotatably mounted on the Y"mechanism support i6 as by a rivet 4l isa gear 42 whose teeth 43 mesh with the teeth of the pinion 19. The gear is provided vwith an arcuate cani and with a 'lug Fixed Von the rectangular portion 37 of the. shaft and projectingT fromboth vsides thereof a rock arm 46 that is provided with a hole in which. is disposed a rod or mounting' nient of the shuttle and also to hold it in V the arm position on the shaft 36.', At one end, the shuttle 49 is providedwith a downwardly depending arm 5l that is adapted to contact at certain times with the projection of the cam gear 42. 'At the opposite end from 51. the shuttle 49 is provided with a projecting.screw-eye to which is secured a rack arm 54 by means of aA pinY 55 that passes through the screw-eye 53 ,and the hole in the rack arm. The rack portion 54- of said rack arm isradapted'` to engage the pinionl ofthe blade holderfsliaft 29. A flat springrr 56 is secured tov the shuttle 49 and presses on the VVend 54? ofthe rack arm A54. thus tending;r to keep said rack 54n in engagement with the 'pinion Sliof they blade holder shaft 29.k ObviouslyVif the shuttle V`49 is moved endwise while thefraclr 54;L is in engagement with the Vpinionl, the blade holdershaft 29 and bla-deholder will be rotated. 'The rack arm l54 is provided with aine-V57 that is adapted lto actas a stop cooperating'withthe camsBO to prevent 'the blade holder shaft 29 fromrotating too far.

4t the opposite end and side of the shuttle 49 from the'arm 5l is a downwardly depending arm 58 with which the lug 45 Vis adapted to contact at intervals. Thus. when the armrl is engaged by the lug 45,'the shuttle 49 is moved on the shaft in one direction VandV when the arm 58 is engaged by said lng the shuttle is moved in the opposite direction. rlho duration of the contact between the lug 45 and therespective arms 51 and 5S is suflieient to move the shuttle 49f'the entire distance permitted by the' groove and pin 52.

A spring 59Y secured support 16' at one end and the rock arm. 46 at the other. tends to hold the blade holder 26 and the blade from the strop 9.

The arms of a fork 60 engage the annular groove 39 of the shaft 36 andV constitute ai support forsaid shaft. The fork 60 has vcrtica'lly alined eyes 61 through which is threaded aV screw 62 whose lower end is held'against endwise movement in the'mechanism support 16.' Thus. vas the screwl 62 is turned, theforlr 6G and consequently the end of the shaft 36 are moved up or down. rhis up and down movement of one end of the shaft.v obviously permits an adjustment of the pressure with'which a blade being sharpened engage the strop. As' the'end of the shaftvismoved up the pressure of theblade against the strop isdecreased. YThe operation of thedevic'e is as follows: Assuming that the*Y blade is in engagement with the strop 9 andV the Vparts are inthe to the mechanism n positions shown in Fig. 3,` it will be noted that the blade is held in engagement with the lstrop 9 against the pressure of the spring 59 by reason of thefroller 48 vbeingr in engagement with the cam 44.V The lower end of the arm 58 is engaged by the lug 45 and theslide block is moved so that the' ratchet 54a slides across the pinion 3l, the rack arm being; free to yield slightly to pass over the teeth of the pinion. As soon as the roller 4S clears the cam 44 the pull ofy the springr 59 causes the shaft 36 to roclcand the blade holder 26 to be moved away from the strop 9. rlhe lug 45 then engages the end ofthe arm lmoving the shuttle 49 and rack arm 54 and rotating the blade holder to reverse the blade. The rack 54' is rheld inv enO'aO-ement witl the l inion 31 j e e P i vstrike thev lugrv 57 on the rack arm 54 and prevent such rotation.

for sharpening various kinds `of razor Y blades. as the position vof the blade holder 26 is `capable of adjustment. lThe device is rlie above described razor strop is adapted? plicated parts to getoutmf'adjustment and it requiresno slrill onthe part off'theperson using it. Y, y
