HONING AND STROPPING DEVICE FQR SAFETY-RAZOR BLADES.

Application filed March 18, 1925.

To all whom it may concern:

Be it known that I, WALTER B. MoFAn- LANE, of the city of Niagara Falls, in the county of Welland, Province of Ontario, Canada, a subject of the King of Great Britain, have invented certain new and use ful Improvements in Honing and Stropping Devices for Safety-Razor Blades, of which the following is a specification.

This invention relates to devices intended for holding safety razor blades so that they may be honed or stropped on an ordinary razor strop, and the object of the present 1nvention is to devise such a holder which will be simple and cheap to manufacture, which will have a minimum number of parts, in which the blades may be quickly and easily inserted and removed, which may be held so that the blade may be honed or stropped in exactly the same manner, and which in weight and size will conform very closely to that of the old type straight razor which is still commonly used by barbers.

I attain my object by means of the constructions hereinafter described and illustrated in the accompanying drawings in which Fig. 1 is a side elevation of my improved device;

Fig. 2 a section on the line 22 in Fig. 1;

Fig. 3 an end elevation of the device;

Fig. 4 a similar view showing a modification' Fig. 5 a plan view of the blank from which the device is formed; and

Fig. 6 a front view showing the parts in open position.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

The handle of my improved device is of the conventional razor form consisting of a pair of plates 1 riveted together at one end Serial No. 165%.

plate a is provided with projections G adapted to pass through the holes in the blade. and the plate 5 is provided with holes 7 into which the projections may extend. T he blank will be formed of material with suflicient spring to cause the plates e and 5 to normally tend to suliiciently spring apart to enable a blade to be inserted or removed.

In order that the blade may have a proper angle to the face of the strop during the stropping operation, the plate 4. is formed with an extension 8, which is bent, as will be seen in Fig. 3, to form a loop of substantially the width of the back of an ordinary razor.

Integral with the plate l is a shank 9, which is pivotally mounted on the pivot pin 2. To stiffen the shank 9 it is preferably bent up to channel form as will best be seen in Fig. 2, and that portion received between the plates 1. is bent up to rectangular form to provide suitable bearing surfaces and will be of such thickness to provide room between the plates 1 for the blade holder when it is in folded position with the handle.

To hold the plate 5 in blade gripping position, the latter is also provided with a short shank 10, also bent up to channel form, the outside. width of the channel being such that it will be received and frictionally engaged within the channel formed by the shank 9. Usually this frictional engagement will be sullicient to hold the plates in razor gripping position, but in any case during the normal stropping operation, the users thumb will normally rest on the shank 10 while the lingers will extend over the shank 9, so that the plates and shanks will be firmly gripped together.

The shank 10 will, preferably, be provided with a tab 11 for engagement by the fingers to facilitate its disengagement from the shank 9.

For blades of the Eveready type, the

projections 6 will be omitted. and the stiffening back strip will be received within the loop 8 as indicated in Fig. 4. As the metal from which the holder is formed must be of a comparatively thick material to give the required stifiness, the plates 4 and 5 will preferably be slightly bevelled to reduce the thickness of the device at the honing edge.

From the above description it will be seen that I have devised a stropping device which will satisfactorily attain the object of my invention as set out in the preamble of this specification.

l i hat I claim is:

1. In a holder for razor blades during honing and shopping the combination of a pair of plates connected together at one end in a manner to prevent movement relative to one another in the plane of their adjacent surfaces, and between which a blade may be received, at least one of said plates being formed of resilient material, the free end said last mentioned plate tending to occupy position 1 the other plate in a direction their surfaces; and a shank in- *"h the free end of each plate. one shanks h a 02,5 vin a recess formed therein in which at least a portion on the other sl'iank adapted to he received when the plates are in blade holding position.

2. In a holder for razor blades during honing and s nprping the con'ibination oi' pair of plates (ODHLOTLIl together at one end in a manner to prevent movement relative to one another in the plane oi their adjacent surfaces, and bet een which a blade may be received, at least one of said plates being 'lorined of resilient material. the free end oi id last mentioned plate normally tendino; to occupy a position spaced from the other plate in a direction normal to their surfaces; and a shank integral with the free end of each plate, one of said shanks being 0! channel form in cross section. and adapted to receive the other shank when the plates are in blade holding position.

3. In a holder for razor blades during honing and stropping, the combination of a pair oi plates connected together at one end in a manner to prevent movement relative to one another in the plane of their adjacent surfaces and between which a blade may be received at least one of said plates being formed of resilient material, the free end of said last mentioned plate normally tending to occupy a position spaced from the other plate in a direction normal to their surfaces; and shank integral with the free end of each plate, one of said shanks having a re- 1 formed therein in which at least a portlon of the other shank is adapted to be frictionally engaged when the plates are in blade holding position.

4:. In a holder for razor blades during honing and stropping a strip of resilient metal doubled upon itself to form a pair of pl ites connected together at oneend in a manner to preventmovement relative to one another in the plane of their adjacent surfaces. and b tween which a blade may be received. the tree end ot one plate normally tendi to occupy a position spaced from the t *0 end of the other plate in a direction normal to their surfaces: and a shank integral with the free end of each plate one or" said shanks being bent into channel shape in cross section to receive and friconally grip the other shank.

lr a holder for razor blades during honing and stropping, a strip of resilient metal donhled upon itself to form a pair of plates connected together at one end in a manner to prevent movement relative to one another in the plane of their adjacentsurfaces. and between which a blade may be received. the free end of one plate normally tending to occupy a position spaced from the free end of the other plate in a direc tion, no mal to their surfaces; and a shank integral with the free end each plate, one of said shanks being bent into channel shape in cross section to receive and frictionally grip the other shank, said other shank having a tongue stamped up therefrom to facilitate its disengagement from the first mentioned shank.
