p epplleation filed IvarchY 1.8, i925. Serial No. 16,392.

My invention relates to improvements in the design and construction of avliolder for razor blades (laminar type, or very thin compared with length and breadth) hav'- ing two cutting or shaving edges opposite to each other, and provided With, means (perforations), practiced in tlienifor relative location in the razor (safety razor), as in the Gillette (trade-name) safety razor and the like.

With this my `design and construction of a holder for Gillette (trade-name) safety razor blades, trie aforesaid shaving blade can be located relatively to the holder in the saine manner as located relatively to the YGillette (trace-name) safety razor, interloclred to the holder by mechanical means as will be shown and explained in ythis specification; and While so firmly held in said holder, the vblade can be resharpened by means of strapping or honing its cutting edges, after being chilled through use in shaving; and in the very same Way, or manual process, as used by an artisan' barber when he vresliarpens his razors of the manual type, by longstrokes of reciprocating character with the sides of the cutting edge of the blade, bearing upon a stretched Yand Vheld taut leather strapv used for 4this purpose, or by honing the sides ofV the cutting edge f the blade uponabrasive materialu stones (commonly called bones) and by the same manual process used by the aforesaid artisan barber in the performance of these manual processes of sharpening hisrazors. 7

The usefulness of this my constructionof a holder for laminar razor blades as set forth above is selfV evident as ali users of such types' of proving the cutting or shaving qualities of 4their razors (safety razors), VGillettes (trade-name) safety razors specially, by adequate, easy and simple manual methods'of eitlierfstrapping or honing the blades they use, Wit-hout the necessity of employing expert operators and complex or ineflicient mechanical contrivances actually dispensed and made use of for the purposes as set forth heretofore. j'

The following is a detailed description of my laminar razor blade holder of the type and character as heretofore mentioned:

ln the' aceonipany'infr drawing Fig. l, is a plan View of the holder with. a Gillettes razor blades Will benefit by im-v location, showing the open position of the holder or osition for the locatinoa orY nositioning and vice-versa of the aforesaid ra# front view of the y Zor blade preparatory to sharpening or re-Y y moving the saine,jprior to or after it has been sharpened bythe manual processes of strapping or honing as set forth. 'y

Fig. 5 is a rsectional `View through line d 1 f i6- i in Fig. 4.;

Tin Fig.` l; Y Y. l y Fit. 7 is asectionalvieiv through line 18-18 in Fig. 4; and Y y F ig. 8 is a longitudinal or lengthwise sectional view through 19,-19 in Fig. l, and looked at' inthe direction ofl the arrows.

ldentical numbers in all the various ligy ures refer to identical details of construction. A i

, ln Fig. l, l isl the body or fraine'of the holder, 2 is the rotative member of the construction, rotating about pivot 3 vfastened and riveted to frame l; 4 are locating pins for Arelrtively `locating laminar blade, as

LIC

' shown by outlines 15,'and fastened by riveting to'frame l; 5 are clearance slot-s or recesses to clear pins 4, .practiced vcircularly, upon rotating member 2, about its center of rotation orvpivot 8, and so causing no interference in its circular movement by the blade locating pins 4; 6 is a plunger with knurled end, for locking in the closed position rotating memberA 2, andretained inH relative position to the frame l by key or pin ,8 pressed in` frame l, and giving to plunger G free axial to-andfro movementsr Within limited axial length determined by cylindrical undercut 7 in plunger 6 andto which pin 8 comes tangent at right angle to rthe' axial disposition of plunger 6 inserted in axial 'bore 9,v practiced Yin frame l and rotating member 2, aligned to both whenv in closed or interlocked position.

'10V and l1 are circularly milled angular recesses, milled or formed circularly `about center of rotation or rpivot 3, in frame l into which lit the similarly formed ends 12 and of the rotating` member EZ; when in axial 6 is a'sectional yvietv throughrline v plane oit' both frame coincidence and disposition as V.shown by Figs'. l, 2, 3 and 8.

ltis a recess or seat practiced upon frame l and whereinv laminar blade l5 is inserted and caused to be tlush with the same axial l and rotating` member 2.

F rom the foregoing enumeration it can be explained:

Tvihen laminar blade l5 has been inserted in its recess ll in frame l, and relatively located therein by locating pins l, While rotating member 2 is in open position as shown in Eig. 4, the rotating member 2 can be rotated about pivot pin 3, swung under or into recesses lO and ll in trame l, and thereon held by formed ends i3 and l2 respectively of rotating member 2 until axial coincidence ot both' trame l andl rotating member 2 permits the introduction of plunger 6 into aligned bore 9 ol rotating member 2 and' Vso cause an interlocking` of 'trame l, rotating member 2 and laminar blade l5; and that While'in this state ot inte1'-relation Yot' above mentioned parts or letails of the to the explanations as' therein set forth and stated, I do claim:

.1. A holder for safety razor blades comprising a frame having a hollow cylindrical handle and a flat 'faced blade receiving portion' provided Yat its extremities with arcuate'slots having' inclined upper walls, said blade receivingportion being formed intermediate its ends with a shallow groove in its upper face, a pai-r oi spaced studs' exlowerV face of suliicient depth to clear thestud-s during the swinging movements ot the member, and means for seouringvthe holder member in alignment with the blade receiiw ing portion. Y

2. A holder tor safety razor blades cornprising' a trame having a hollen7 cylindrical` handle and a flat 'laced blade receiving portion proif'ided at its extremities with arcuate slots having inclined upper Walls,

said blade receiving'portion being. formed intermediate its ends with a shallow groove Vinits upper face', a pair ot spaced studs extending through and above the groove to position a blade in the groove, a pivot se- `cured substantially centrali 1 of the blade recei'ving portion` a holding member rotatable on said pivot and having arcuate ends u'itl inclined' upper Walls adapted to iitA in said slots or swing therethrough to either side ot the trfme, said holding member beingA also )rovided with spaced arcuate Grooves L ii? in its lower face ot su'iiicient depth to cleat' c the studsA during the swinging movements of the member and at its Yrear extremity with a*semi-cylindrical bore, the blade receivingportion being also provided with semi-cylindrical bore at its rear extremity adapted to align With the bores inV the holding member and in the hollow handle, and

a locking pin mounted Within rthe hollow handle and adapt ed to be moved intoloeli- Ving position Within the aligned bores in the blade receiving portion and the holding` member.
