o. L. JOHNSON RAZOR BLADE sTRoPPING HOLDER Filed Sept. 20, 1928 4 Inventor a, Jai/NM By Attorney Ll l) Patented Jan. 14, 1930 PATENT i' FFIC'EY OSCAR L. JOHNSON, or SISTER BAY, WISCONSIN RAZOR-BLADE-STROPPING HOLDER Application led'September 20, 1928. Serial No. 307,300.

The present invention relates to improve# ments in safety razor bladeV holders and has for its principal object to provide adevice for -holding a safety razor blade during the sharpening of the cutting edges thereof.

An important object ofthe present invention is to provide a safety razor blade stropping holder which includes a pair ofcoacting hingedly connected clamping plates between which a safety razor blade is adapted to be secured against slidable movement, means being provided for securing the clamping plates together, additional means being provided for automatically swinging the top clamping plate Vupwardly 'when the locking means is released to facilitate the removal of the blade from the holder.

Still a further object is to provide a safety razor blade stropping holder of the above mentioned character which is simple in construction, inexpensive, strong vand durable and further well adapted to the purposes for which it is designed.

Other objects and advantages will become apparent during the course of the following description.

Inthe accompanying drawing, forming a part of this specification, and in which like numerals indicate like parts throughout the same: l

Figure l isa top plan view of the safety razor blade stropping holder embodying my invention, showing the clamping plate in closed position, and holding the safety razor blades therebetween,

Figure Q'is a similar view showing the top clamping plate swung to a horizontal position away from the bottom clamping plate, l`

yFigure 3 is a longitudinal sectional view through the lholder and Figure 4 is a transverse section taken approximately on the line 4 4 of Figure 1.

vIn the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral yl designates generally my improved safety razor-blade stropping holder, the same com# prising a hollow elongated handle 2, the upper forward end portion thereof being out away.l Y-

A flat elongated strip 3 is arranged within the handle 2 and formed on the forward end of this strip is the rigid bottomV clamping plate 4, the same being disposed across the cutaway forward end portion of the hollow handle The strip 3 may be secured within the hollow handle 2 in any suitable manner. Above the strip 3 andeXtending transversely' across said strip, are spaced. guide straps 5, the purpose of which will be presently described.

The clamping plate 4 may be soldered to the upper edge of the cutaway portion of the hollow handle and adapted for cooperation with the bottom clamping plate 4 is a similar shaped top clamping plate "6, said clamping plates being hingedly connected together along their rear edges as at 7 An arcuate shaped packing plate 8 is soldered to the outer face of the top'clamping plate 6 so that when the clamping plate 6 isdisposed on top of the clamping `plate 4, the arcuate portion 8 will form an extension of the hollow handle 2 as obvious from ther construction disclosed in Figures l and 3.

i Extending upwardly from` the bottom Y clamping plate 4 adj acentthe forward longitudinal edge thereof are the spaced pins9 that are adapted torpass through the usual opening provided incertain types'of safety razor blades and the adjacentfendl portion of the top clamping plate is formed with openings l() to accommodate thel pins 9 when the top clamping plate is disposed in superposed relation withV respecty tol the Vbottom clamping plate as will be presently described.

The clamping plat-es are ofsuch width f as to be less than the widthof the-razorV blade whereupon the cutting edge of the razor blade will protrude beyondfthe free longitudinal edges of the coaoting clamping plate in the manner'as shown in Figuresfl and 4.

My vinvention further includesv the provision of means for positively securing the clamping plates in a closed position and to this end, a locking bar 1l extends longitudinally through the hollow handle 2 and is arranged for slidable movement'betweenthe top face of the strip 3 and the guides 5 as suggested in Figure 3.

The locking baris in the form of a narrow strip of metal and is of a length greater than that of the hollow handle. The outer end .of the lock bar is bent to vform a hook 12 for detachable engagement over the outer ends of the clamping plates 4 and 6 andthe locking bar is further formed at a point iiiwardly'of the hooked outer end 12 with a lstruck out hook 13 that is. operable. withinV registering openings 14 and 15 formed in the inner end portion of the clamping plates 4 and 6. v

The hook 13 is adapted to eiigagewith the inner end portions of the clampingi plate. r A

head or knob 16 is carried by the inner endsof the ylocking bar 11 fer` disposition outwardl of the jinner end of the handle where y to actuatesaid lock bar.

`An eXpansible coil spring 17 is connected at onerend to the intermediate .portion Vof the locking ban/thel other end being securedvto oneofl the transverse strapsas shown very clearly in theedotted lines in Figure 2.`

This spring 17 normally xurges the locking bar 11 inwardly toward the'fre'e end portion of the handleQ., Y n

f When the knob` or head 16 is `pushed inwardly ,against` the,tension of lthe, coil` spring 17,.,the, hooks 12and 13are disposed in 4an inoperative position. The razor blade Athat is to ,bev sharpened is vthennpositioned. on'the bottom plate 4'after whichthe top clamping plate 6. is swung over ontop of 'the blade rwith the pins 9 protruding through the opening 10. l

during theiise of the same in str-popping ory sharpening the blade.

After the bladehas been sharpened, the.

,; same can beV readily and easily removed from the holder by'. pushing -forwardly on thel knob 16 so asto disengage the hooks 12 and 13from cooperative engagement with the Y clamping plate and a spring pressed plunger 18jthat iscarried by the bottom portion of the forward endrofrthe handle ZandewhichY is operablerthrough an opening provided in the rear edge portion of the base platea will exertr an upward pressure on the hinged top plate 6to move the saine upwardly and away from the bottoni clamping .plate so that said top` clamping plate canV be easily swung to an open position and the blade removed It is of course 'understood that the spring pressed plunger 18VV is held under,` tension when the clamping plates are securedA together.

It will thus be seen fi'om the foregoing description, that'I have rovided a safety .cost and the same will be 'strong and durable.

' While I have shown the preferred embodiment'of'fmy invention, it is to be understood that'various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the inl lade stropping hol er .that will be at all times eflicient and reliable in carrying out vention and the scope of t-hev appended` v claims'.V n Having thus 'described my invention,

i what I `claimas new is:

1.] A safety razor blade stropping Iholder comprising a hollow'handle, Va bottom blade, clamping plate earriedby' the forward end of the handle, a coactiiig top clamping plate liingedly connected alon one of its longif tudinal edges to theV adjacent Vlongitudinal edge of the bottom clamping plate, and means for seeuring the clamping plates together to hold a safety razo'rbladel thereav between, said means comprising, a slidable. locking bar extending throiigh'the handle and below the bottom clamping -plate,.th'e` forward endof said clampingbar being bent to form a hook for engagement over the Vouter ends ofthe clamping plate, a .hook
