BLADE HOLDER Filed DSG. 20. 1950 Fly. 3.

Patented Aug. 9, 1932 JAMES M. MAKER, OF FREMONT, NEBRASKA BLADE HOLDER Application filed December 20, 1930. Serial No. 503,800.

This invention relates to a blade-holder particularly adapted for holding the blades ot' safety razors for honing or stropping.

Une of the objects of the invention is to C? provide a device which will be convenient in use when removing the lade from the holder or when mounting the blade therein.

Another object is to provide such a construction that the blade will be securely held Tril and to provide a suitable handle so that stroppihg may be conveniently and accurately accomplished.

The invention includes the use of elastic metallic strips of such form that a pair of i handle-members may be produced each being integral with strip and which conduces to 'economy in manufacture.

Also the invention includes elastic metallic strips ot such normal curvature that the blade will be held more firmly than ordinary, and for this purpose one of the curved strips is provided with a stabilizing plate for stroppin the blade.

With the foregoing objects in view and others to be mentioned the invention presents a new and useful construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the accompanying drawing, it being understood that changes may be made in Jform, size, proportion and minor details, said changes b-eing within the scope of the invention as claimed.

In the drawing, Fig. 1 is a side view of a blade-hole er embodying my invention, a stabilizing-plate being shown and the pair of handlemembers being broken away to show locking means. Fig. 2 is a plan view of a safety razor blade.

Fig. 3 is a side view showing the device in closed or locked position, the stabilizingplate being omitted, and Fig. 4 is a plan view of the device.

Fig. 5 is a detail showing a hingeable connection for the pair of elastic strips employed, this being a modified form of the invention.

Fig. 6 is a broken away detail showing a milled or rugose surface for the inner side 3. Fig. 8 is an enlarged transverse section on line 8 8 of Fig. 3. Fig. 9 is a broken away plan view showing a stabilizing-plate and portion of the device.

Referring now to theV several figures of `midway between its ends to form a small reinforcing spring 10, a pair of semi-circular handle-members 11, each having a reduced terminal part 12; that part of each flat strip 9 and 9 which carries a. handlemember 11 and its reduced part 12 being rectilinear as indicated at 13, and that part of each strip 9 and 9 between its handlemember and spring 10 having a normal uniform, longitudinal, inward curvature as indicated at 14.

As thus described the strips 9 and 9 are alike in all respects, except that one of the strips is provided with a stabilizing plate 21. This stabilizing-plate, preferably, has a greater width than the width of the curved parts 14, as best shown in Figs. 4 and 9 of the drawing, and is secured to one of the parts 14 by electrical welding. Each strip 9 and 9 is provided with a slot 15,

the slot in the'strip 9 having a lesser width than the slot in the strip 9, as clearly shown in Fig. 4 of the drawing. I provide a clamping element or slide-piece having a comparatively large Vhead 16 and a lesser head 17, said slide-piece being carried by the strip 9 since its head 16 has a greater diameter than the width of the slot in said strip 9. Numeral 18 indicates a recess which opens on the slot of the strip 9, said recess having a greater diameter than the diameter of the head 16 of the slide-piece to permit said recess to operate as a passageway for the head 16 to move therethrough.

In operation, the blade 19 may be inserted between the curved portions 14 of the strips 9 and 9', and placed on the stabilizing-plate 21. The operator, with one of his hands,

k.may then grasp the handle-members 11A and of the pair of elastic strips employed. Fig.

may move them toward each other, and since no 7 is a transverse section on line 7 7 of Fig. 100

, vstabiliZing-plate.

the portions 14 have inward curvatures relative to each other the blade will be rmly pressed therebetween before the rectilinearpart-s 13 move into engagement.

When the parts 13 of the strips 9 and 9 move into engagement the head 16 of the slide-piece -will have passed through the recess-18 and the operator then moves the slide-piece in the slots toward the-adj acent free ends of said strips for securing said strips in locked relation.

After the device has been used, the blade may be readily removed. For this purpose the slide-piece is moved :in Athe slots L15 in a reverse direction to permit the head 16 to move through the recess 18, said-strips automaticallyrmoving to Ytheir :normal iV-shaped position shown in Fig. y1.

It will be appreciated 'that if -the strips 9 and 9 were both re('Jtilinear throughout 'their'entire lengththe blade 19, Iwhich may be yentirely attenuated, would be held less securely, but since the partsw14 have -relative inward Acurvatures and a stabilizingplate'21 is provided, the blade,\.on account yof this construction, will be rigidly held,

and during the voperation of stropping will notbe moved from its gripped position.

Since the stabilizing-plate `has a lesser width `than the blade, it does 'not interfere with the operation o'f Vstropping. It pro- Avides a; seat for cheb-lade, and lsince the blades of safetyrazors are extremelythin they are occasionally broken during 'their sliding movements on the strop, `and Athis may be prevented by use of t`ii-e-plate21l-Vv However,

in some instances the blades may have an jadequate'thic'lrness 'to avoid breakage, and

I do not'wish to belimited to the use of the llt will be appreciated, yby referring to 'Figs 1, 3,V 'stand 8 of the drawing, that the rslide-piece will b e protected fromaccidental displacement since the slots 15 are disposed 1in .the reduced parts 12.of the handle-menibers 11.l Also it will be seen that, since the slots'and slide-piece are 'disposed in the reduced `parts 12 theslidevpiece maybe conveniently moved by an operator.

- Tofacilitate maintaining a'bladelin a sta- Vv'tionary position during :the operation of `str'opping, the inner sides of .the parts 14 of 'the strips may be of rugose or milled con struction as shown in Figs. 5 and 6 of the drawing.

In'th'e modiiied formlof the invention "shown in Fig. 5, two separate strips are used and are lconnectedby a terminal hinge joint 20, all other parts beingl the same as described,

'and since operation will be the same I vmay 'employ'this hinge liointif'desired as it pro vides'aconvenient and economical construction. It will be notedthat'the pintle for the vhinge v is disposed parallel with'the liiat sides of thestrips 14.

yhandle-members 11. the device is approximately of il-shape and It will be understood that, by use of the device, razor blades diifering in form and size may be held in stationary position between the curved portions 14 of the strips.

It will be noted that, in Fig. 3 of the drawing, the strips 9 and 9 are disposed practical ly parallel, their. normally curved parts 14 being pressedfinto that-positionfby-use of the The normal position of arms being curved outwardly from each other to inherently hold'the arms irl-divergent relation, each of said arms having an outwardly curved handle portion near its outer end and the handle portions adapted to register wnen the arms are pressed together, the free ends'of said arms having inner opposed flat faces adapted forabutting engagement when the arms are brought together, said outer end flat port-ions h ving registering slots therein, a locking member carried by one of said arms operable in said slots for intei-locking the arms together when closed, and a supporting plate secured across the inner vside of one of said arms adapted to receive a razor blade thereon, said arms adapted to clamptherazor blade between the arms with the cutting edges of the blade extending beyond the opposite longitudinal edges of the arm.

In testimony whereof, l aix my signature.

JAMES M. MAHER.
