CHARLES W. SPEECE, or CHICAGO, ILLINOISA Y RAZOR-BLADE' HOLDER.

' Specification of Letters Patent. Application filed November 10.1906. are No. 342,886.

Patented ma 28, 1.907.

To a. whom, it vii/(Ly concern:

Be it known that I, CHARLES W. SPEECE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new andiuseful Razor- Blade Holder, of which the following is' a specification.

My invention relates to cutlery and has special reference to razors.

The objects of theinvention are to provide a temporary holder for supporting during honing or stropping the thin Wafer'*-blades used in safetyrazors so constructed and arranged that it willdo more than merely hold the wafer-blade, and to provide a holder which, in combination with the wafer-blade, will constitute substantially an ordinary hollow ground razor having a thin, .removable cutting-blade so that the cutting-portion of j the blade maybe renewed at small cost when damaged or when found lacking in uality.

With the above-named general jects in view my invention consists in the novel con-.

struction and combination of parts hereinafter described in detail, illustrated in the drawing and incorporated in the claims.

In the drawing Figure 1 is a pers ective I view ofa razor and wafer-blade-hol er em- ,bodying my invention. Fig

2 is a side elevation partly in section.- ig. 3 is an enlarged section taken substantially on line .33 of Fig; 2.

Fig. 4is an enlarged section, takenon line-44 of. Fig. 2. Fig. 5 is a trans-- verse section of the holder, partly broken away. Fig. 6 shows substantiallyione-half of the clasp portion or head-pf the tool. Fig. 7 is a full size view of an ordinary wafer blade. I

The device herein shown comprises a head 2 which constitutes aclaspi two leaves or v sections 3 and 4 hinged together at 5.- The opposite ends ofthe two leaves or sections 3' and 4 are formed into two halves of a threaded tang or socket portion, which is shown as slightlytapered and as having threaded engagement with a threaded and tapered socket 8 in the handle 9. In order to insure a true adjustment of thethreaded halves 6i and 7 upon each other I secure a pin or stud 10 on theinner face of the leaf 3 and rovide the leaf4 with an a erture 11 which ts the projecting part of t e pin 10. The'adjacent inner faces of the hinged sections 3 and 4 are "recessed, the section 3 having a. recess '12 (Fig. 6) which substantially fits the blade 13 (Fig. 7). The ordinary form of blade has .in the ordinarysafety-razor. 'Where the tions are equal to the thickness of the blade,

These studs will then engage the apertures 14, The curved ends 16 and 17 and the abut- .ments- 18 and 19. formed the section 3 are also adapted to .hold the 'blade firmly therebetween. Therecess 12, where no. adjustment of the projecting edge 20- (Fig. 3) is desired, will-be made to conform with theconfiguration of the blade,

I have provided a construction," which will permit adjustment of-the blade 13 so that its edge 20 maybe projected more or less, as

may be desired, or to provide for the decrease in width of the blade due to frequent grindings or sharpenings of its edge or edges 20 and 25. In the recess 26 is an elastic pad 27,'which ma be made ofrubber or any suitable materia which will" yield ,to ressure.

This pad is so arranged that it Wll firmly press against'one' side of the blade inged sections 3 and 4 of the head 2 are [closed as shown in Fi The compressed material'in'thepad Wlll tend to expandinto the perforations 14 when the blade is clamped between the two sections or leaves of the head, .and *prevent sliding movement of the blade under the strain imposed upon it while being s'tropped, ound or honed.

.As shownin ls i gfigthe recess 26 isgradually: deepened 'toward the back of the head 2 wedge shaped. This gives it substantial bod or thickness where it need not necessari y be very thin and comparatively deficient in elastic support under the blade, as at the edge of the head 2, designated'at 28. As shown best in Fig. 3, the head is substantially triangular in cross section, like an ordinary razor-blade, and .its sides are slightly finest cutting material are and can be manublade is to occupy a fixed position with ielation to thehead 2 studs 15, whose projecby the'recessing of when the v and the rubber or elastic material 1 27 is may be provided in the face of the recess 12.

concaved, said sidesmeeting. substantially As shownin factured at an exceedingly small cost, so that holder embodyingmy invention also involves but very little expense. The two sections 3 and 4 may be cast including their hinge and threaded tang portions and the method of' joining handle and tang and, at the same time clamping the two parts of the head together involves substantially only a minimum of expense. In order that the simple 'oint between handle andhead shall be'fii'm provide shoulders 29, 29 againstwhich the threaded socke't of the handle may be screwed up as tightly as may. be necessary and leave sufficient space 30 between the end of the shank and the'bottorn of the socket to.

insure a firm friction engagement between the rim of the socket and the shoulders 29. The threaded shank is ta ered in order to facilitate the insertion of t e shank into the socket, theouter end of the socket being large and roomy "for the small end of the shank; Again, if the blades shouldvary in thickness so that the two halves of the shank come together with varying degrees of proximity the tapered hole and shank will adjust themselves to such variations within certain reasonable limits owing to the compressibility of the pad 27. In the event that they do'not come together closely and the shank is wed ed into the socket the shoulders 29-will, 0' course, not come into contact with the end of the socket-part, but the pad 27, being compressed upon the blade and between the leaves 3 and 4, will exert outward pressure upon said leaves and thus tend to expand the two halves of the shank against the handle socket. One turn of the handle after the threaded parts have taken hold is ordinarily sufiicient to tighten the handle on the head, and the operation of removing the handle, opening the-head, inserting a blade and again closing the parts may, accordingly,

be performed very rapidly. The only part of my improved razor'which need be made of ordinary razor-material, or fine steel, is the thin blade and when this is damaged or nicked the damage amounts to only a few pennies instead of the loss of the whole razor,

and-may be repaired instantly. Further-- morethe same tool can be provided with any kind of a cutting edge desired without the aid of skill by simply selectin and inserting any one out of a dozen wa'er-blades, the

whole lot of which would cost less than a cheap razor.

.The operation of the invention as a holder for safety-razor-blades while the latter are being ound, honed or stropped will be obvious om the foregoing description. The tapered, or knife-edge, form of the head when laid flat upon a strop or stone brings the surface of the latter to the proper angle with reference to the edge of the waferblade.

I claim as my invention- 1. A razor blade holder comprising a pair of leaves or sections which are hinged togethdr and have threaded tan portions adapted to enga e a threaded soc et; a handle provided wit a threaded socket adapted to engage said tang portions to lock said leaves or sections together, and elastic friction material between said leaves or sections.

.2. The combination witha wafer blade, of a holder'therefor which consists of a pair of hinged to ether leaves which constitute a blade-holding head; a handle for said head; means for locking said handle and head together; said wafer blade arranged between the leaves of said head so that only the cutting edge of said blade is exposed; said head having hollowed or concaved sides which substantially meet at the edge of said blade, and elastic material compressible upon the blade between the leaves of said head-for the purpose of holding said blade against movement relatively .to said head.

In testimony whereof I have hereunto set myhand in the presence of two subscribing witnesses.
