Appuation ied May a,4 1923. serial No. 636,453.

0 all whom 'it may cof/werft:

Be it known that I, MICHAEL CROUGH, a citizen of the United States, residing at Ilion, in the county of Herkimer and State of New York, have invented new and useful Improvements in Safety-Razor-Blade Holders, of which the following is a specication.

This invention relates generally to improvements in safety razors,l and particularlyto improvements in safety razor blade holders.V Y

One object of the invention is to provide a holder having a tang portionr and a handle, simulating, in general, the appearance and structure of an ordinary non-safety or old style razor and which allows a person to shave7 and a blade held in the holder to be resharpened, honed or stropped, with all the ease and conveniences afforded by the old style razor.

Another object of the invention is to pro'- Vvide a holder which is adapted to hold and thereby permit of the use of safety razor blades 'of any of the forms 'in general use, according to the fancy of the userk or as circumstances may require.

Still another object of the invention is to provide a safety blade holder which'will rmly and securely hold a blade in position. which is adaptedv for the readyfand convenient application and removal Vof a blade, and which is `also compact in form,Y

and susceptible of being easily manipulated and of beingV manufactured andsold at a comparatively low cost.

The invention consists of the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being. had to the 'accom.

Figure T is a similar viewshowing Athe blade clamped therein,

ln the practical embodiment of my invention l provide a .safety blade holder comprising a holder portion proper 1, a tang portion 2, and a handle 3, simulating in general the appearance of an old style razor.

The holder portion lconsists of apair of clamping plates 4 and 5f, which are similar in form and construction to each other.

Each'plate comprises aV bodyportion 6 hav-V ing at its rear or back edge anV o-utturned longitudinally extending flange 7 and'havingat a point adjacent to but in Vrear of its front edge an inwardly offset portion 8. The portions S dispose the front portions 9 of the plates closer to eachv other than the body portions 6, and `these portions 9 are provided with -inner blade ,clampingx faces 10, which are parallel vviththe inner faces of the body portions of the plates, and outer beveled faces 11 which converge in the direction toward the fro-ntedges ofthe plates. As shown, the tang portion 2 is composed of strips projecting `from the Vinner ends of the plates and which have their outer ends arranged to straddle the handle Y 3 and which are pivoted thereto by a pin or rivet A12.4 VThis'pin or: rivet 12 passes throlighV registering openings inl the handle and tang strips and has at one end a taperedV head 13 litted in a correspondingly'shaped countersink portieri4 ofthe openingy in one of the tang strips and is formed at its ol* Y Y themselves to certain" rocking motions of the plates 4 and 5, as hereinafter described.V

The pla-tes 4l and `5are loosely Vjoined ad- ;jacent to their ends, Vbyheaded pins or rivets 15, Vpassing loosely throughV openings 16 Y therein. These pinsare spacedl a suflicient distance apart to permit -a-safety razor bladeV of anyr length Vused Ato be disposed between the' pins and in the space between'the plates 4 and 5. The pins are arranged'in line with the Vinner' 'ends of V-shapedportions 17 vstamped -in`wardlyfrom the bodyportions ofthe lplates and have theinheads' seated in thefchannels or groovesV formed fin the louter faces of the plates by the correspond ing depressions'. The vertices lof these pairs -of Vf-shaped'portions at opposite ends of Y the Vplates abutfand normally space' the y plates such motion is permitted to adapt the portions of the plates above and below the line of the rivets to rock or tilt in op posite directions, so that in one direction of rocking motion of the plates the jaws or clamping portions will close or move inwardly towards each other, while in the Y opposite direction of movement of the plates the jaws 10 will open or move outwardly and away from each other. The described pivotalconnection between the tang strips and handle adapts said strips to rock with the plates without disconnection fromV the handle, as the extent of spreading action of the tang strips will not be greater than that allowed by the pins 15.

Pivotally mounted upon pins 18, loosely engaging openings in the plates a and 5, are locking wedges 19, arranged adjacent rto the ends of said plates so as to be swung into the space between the plates or outwardly beyond the ends of the plates. These ywedges have milled gripping surfaces 20 for engagement by the thumbs or fingers of the operator, whereby said wedges may be manipulated. posedy as to project above the flanges 7, when the wedgesare in locking position, so as toV enable the wedges to be forced tightly into such position as well as to be swung vertically for a releasing or unlocking action.

Figure 3 of the drawing shows the parts of the holder when in position to clamp a razor blade, and Figure 4L shows the parts of the holder in blade releasing position.

, When the locking wedges 19 are swung out.-

wardly, it will be understood that the plates 4 and 5 are'free to be relativelyV rocked on f the trunnions 17, so as to allow the upper edges of the plates to come close together and the clamping jaws 9 to spread, while when the loclringvwedges 19 are swung inwardly the upper portions of the plates 4 and 5 will be spread or moved outwardly, while the jaws 9 will be moved inwardly to clamping position. In Figures 2 and 3 I have shown a safety razor blade 21 of the Gillette type applied for use. Blades of this ytype are thin metal blades having opposite longitudinal cutting edges, which are devoid of a bead or reinforcement, kBladesof this type may be inserted for use directly between the clamping faces 10 of the jaws 9 at ythe front of the holder and tted in place E so that the body of the blade will be dis-y posed between the plates l and 5 and the acting edge of the blade caused to project a desired distance beyond the front edges 0f rl"he surfaces 2O are so disthe jaws. The blade may'then be secured in position by swinging the wedges 19 inwardly, thereby closing the jaws 9 and forcing their clamping faces 1G into engagement with the sides of the blade, firmly clamping Vthe latter in position. When the blade is thus applied, the device may be used for shaving like an ordinary old style razor and faces 11 in these operations serving to support and guide the' holder at the proper angle conforming to the bevel of the edge kof the blade. In honing a blade, after one edge has been honed, it will be understood that the blade may be reversed in the holder and the other edge honed in an obvious manner. The surfaces 11 are of such degree of bevel as to reduce down lthe front edges of the jaws 9 so that they will come quite close to the projecting edge of the blade, allowing the blade to be brought as closely as desired to the surface of the skin for as close a shave as may be desired by the user. ln releasing a blade, it issiniply necessary to swing the wedges 19 outwardly, whereupon by pressure on the'upper portions of the plates 4 and 5 the jaws 9`may be spread to y.allow the blade to drop out or to ybe y Vdropping down in position between the'jaws 9, as vshown in Figure 7 so that upon swinging the wedges19 inwardly toclosed position the jaws 9r willbe closed to firmly clamp the blade. Suchblades may be released and removed by reversal of the operation described. ()ther blades of this general type may be used in a similar manner, rendering the device adaptable for the use of any of the forms of safety razor blades now commonly employed, either byapplication and removal via the front or the rear ofthe holder as hereinbefore described.

From the foregoingdescriptio-n, taken inV t connection with the drawings, it will be seen that my invention provides a safety razor blade holder which is not only adapted for the use of all kinds of safety razor blades,

but holds the blade so that it may be employed for shaving, stropping, honing and resharpening aotionslike an ordinary old style razor, the convenience of which will be manifest. Also it will be seen that the invention provides a simple and inexpensive type of holder which may be readily and conveniently manipulated to clamp o-r release a blade and which will firmly andsecurely clamp the working blade in position.

The construction may be such that when the holder` is not in use, no blade being held therein, the handle may be swung into the space between the jaws 9, or the construction may be such that, when the wedges 19 are swung outwardly` the handle may be swung into the space -between the upper edges of the plates l and 5, thus adapting the device to be folded like an ordinary old style razor for convenience in storage or transportation.

Having thus vfully described my invention, I claim 1. A safety razor blade holder comprising two loosely connected plates having instruck contacting portions o-n which the plates are adapted to rock on a longitudinal axis, said plates being provided with blade clamping jaws in advance of such axis, and means movable into and out of the space between the plates in rear 0I" said axis for rocking the plates to'close the jaws and Jfor holding said jaws in clamping position. Y j

2. A safety razor blade holder comprising two plates having offset port-ions forming Y for .closing the jaws and locking them inolosed position. Y

3. safety razor blade holder comprising two plates having offset portions forming jaws at the front thereof normally closer to each other than the body portions of the plates, said jaws having instruek contacting portions in rear of said offset portions, loose connections between the plates limiting their outward movement and cooperating with said instruck portions to adapt said plates to have rocking movement on a longitudinal axis, and wedges pivotally mounted between the ends of the pla-tes in rear of the instruck portions for spreading the plates in rear of said instruck portions to cause the jaws to move inwardly to clamping position, and

for Vlocking them in such position.

In testimony whereof I atlix'mysi ature.

MICHAEL CRO GH.
