1 1f Fig. IG'isaplan-Of one form of razor 1 "adaptedto he s Y I (isfa'plan ofanother form-'of-safety l-azd l' blade. .e The i'id-evice R101. holder has aflzhandle 1( itsends-terminating in proximity to" the g 111g a razor blade betweenthehnembers.. In the central. part-of thefaceofthe jaw mem; v
'iberlorstrip 16 opposed to'the jaw member 14: may be a'groove 17 extending through- A i cates withthe groove 15 of the jaw member posite parts ofthe'side edges of the jaw move close upon the grooved face of the aw member 14. Pro ecting outwardly ot the slot 12 of the handle from the end of the stem 18 opposite to the jaw member 16 is a head or knob, as 20, for permitting the stem and the jaw member 16'to be slidably moved within the handle and upon the jaw member movement and to prevent the stem 18 fromv moving entirely out of the l1andle-.-On op.-
member 16 adjacent the stem 18 are two clips. or hooks 21, 22 which are bent over 111 movable engagement on the side edges of the rigid jaw member 14 for holding the jaw members in relative'closely spaced positions so that the razorbladesmay be accommodated therebetween.
On the. slidable jaw member 16 may also be one or two spaced corresponding yielding clamps or ejectors, as 23, 23 for servingto holdthe blades between .the jaw members,
and. each of these ejectors is in the form of a spring finger which may be struck out of the bottom of the groove 17 of this member so-that one of its ends is free. Both of the able jaw niembeigand on the free end of each finger may be a head or enlargement 24. The spring fingers 23, 23 are also of lengths that when a form of razor blade, as C, having spaced holes, as D, is positioned between the j aw members the heads 24 of the fingers will engage one or two of the holes of the blade,,or when the form of the razor blade B is between the jaw members the heads 24 of the spring fingers will clamp the blade by engaging the rib A of the blade.
The device is employed for sharpening razor blades by moving the knob 20 for moving the stem 18 outwardly of the handle to adjust the slidable jaw member 16 its maximum distance beyond the free end of the jaw member 14. The razor blade is then arranged on: the slidable jaw member 16 over its fingers or clamps'or ejectors. 23, 2S, and the slidable aw member with the stem 18 and knob 20 are reversely moved to cause 1 the blade tobe removably clamped between both jaw members. The holder is manipulated for sharpening the blade in usual manner, and afterward .by moving the knob 20, stem 18 and the jaw member 16 outwardly from the handle 10,. as above explained, the heads 24 Off the fingers 23,;23 lwill engage and carry the blade alongwiththe. jaw
member 16. The blade may then: .be removed such changes as fairly; fall withinthe scope I thereof. i H
Having thus described my'inventio-n, I claim as new and desire to secure by Letters Patent: Y
14 razor blade holder, comprising a-v tubular handle having extending onapproximately asimilarrelativeplane from one of its ends a fixed rigid strip member for supporting the razor blade, a second strip slid abl'e onthe fixed strip memberxfor clamping the razor blade, hooks on the side edges of the slidable strip member overlapping. the side edges of the fixed strip member for loosely holding the slidable strip member in movable contact with the fixed strip member, two spring fingers protruding outwardly of the groove of the slidable strip member, each finger having anunattached end with a head forengagingand. carrying the razor blade with. the slidable'strip memher when moved from contact with the fixed strip member, and a stem on the slidable strip movable inwardly and outwardlyof the tubular handle for moving the slidable strip and its finger.
