U. A. HUBBS. SAFETY RAZOR. APPLIOATION'I'ILED JAN. 8, 1910.

Patented June 6, 1911 atto'huu; (Pp I CHARLES norms, of BROOKLYN, new YORK:

i To allmzhom it may concern:

-Be'it known that I, CHARLES A. Hones, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Safety- 7 Razors, of which the following is a specification: 7

The invention relates to improvements in safety razors, and it consists in the novel feat-ures, structure and combinations of parts hereinafter described, and particularly pointed out in the claims.

The object'of the invention is to provide. a safety-razor; of extreme simplicity. and durability'and capable of ready manipulation in the matter of'applying and removing the blades.

A. furtherfpurpose of the invention is to provide a sa et razor whose frame may be freely opened up and cleansed with the least amount of trouble and delay, and a further object of the invention is to provide a safetyrazor composed of a-minimum number of parts-and capable of ready manufacture at small expense.

The safety-razor of my invention, aside fromthe-blade, preferably comprises but two separable parts, one being the handle and theother the frame for holding'the blade. Which-frame I form of two hinged parts.

The-invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which:

Figure 1 is an edge view of a safety-razor embodying my invention; Fig. 2 is a like view of the samewith the blade and its holdingframe shown in central vertical transverse section; Fig. 3 isa front view of the same, with the handle partly broken away; Fig. 4 is a view taken from the top of Figs.1'1,,'2 and 3; Fig. 5 is a corresponding view omitting the blade and showing the hinged guard-plate as swung from operative relation'to the back or base-plate; Fig. 6 is a section of the same on the dotted line 66 of Fig. 5, and Fig. 7 is a detached section through a portion of the back or baseplate, guard-plate and blade on the dotted line 7.7 of Fig. 4.

In the drawings, 10 designates the handle of the safety-razor, ll the frame to which said handle is applied and 12 the blade held by said frame. The' handle '10 is an ordinary rod of metal having on its inner-end specification of Letters Patent.

a threaded stem or screw 13 and shoul der let. The blade 12 -isan ordinary thin steel blade having a sharpened edge and will be understood without special description. The frame 11 is of-novel construction and comprises a base or back-plate 15 and a guard plate lti sa-idiplates being hinged together. The base or baelr plate 15 contains a threaded aperture 1'7 t o receiv e the screw 13 on the inner end of the handle, and at ends saidbase or back-plate 15 is formed with the right angular flanges or lugs 18 whose upper ends constitute ears which are apertured to receive and form bearings for the pins or studs 19 formed on the upper outerend portions of the plate 16, 1 said plate 16 beinghinged to the plated-5 by means of said pins or studs and said bearing apertures. The plate 1.5 is also forme with the inwardly extending lips 20 which lips are preferably at the lower end portions of the plate15 and extend inwardly toward each other over the body of said plate bnt suitably spaced therefrom. 5

The plate 16 is formed on its outer surface adjacent to its ends with slight shoulders 2L'upon which the blade 12 is placed, the ends of the blade finding a bearing or seat "on said shoulders and being them held slightly spaced'from the main surface of the plate 16. One purpose of the shoulders 21 is to keep the edge of the blade from scraping along the plate 16 during its application to or removal from said-plate, thus lessening the-tendency of the edge of the blade to become dulled or injured. I I The lower edge of the plate 16'is formed with the guard or comb 22 whose teeth curve from the body of the plate inwardly toward the handle 10 and may be of any suitable or usual configuration.

The plate 1-3 at its lower corners, at the base ofthe shoulders 21, is provided with, shoulders 23 against which the extreme end portions of the edge of the blade abut and which arrest the blade during its application to the holder at the correct position for the same. In applying the blade to the plate 16, said blade willbc placed on theshoulders 21'and then slid downwardly upon the same until the lower corners of the blade become arrested by the shoulders 23 and thereupon the blade will be secured in position, as

The plate 16 is formed in its .side edges with the recesses 24, and these recesses cortially parallel with the main surface of the plate 16 being inclined downwardly and plate 16, said li s being spaced from said plate 16 to a su cientextent to enablethe blade 12 to be placed on said plate 16 and slid behind said lips, so that finally the lips 20 become disposed at the outer side of said blade. The base or back-plate l5 and hinged plate 16 stand at an angle to each other, the

inwardly toward said base or back-plate. When the plate. 16 is folded inwardly toward the plate 15 and the blade 12 is applied to the plate 16 and slid behind the lips 20, the blade will take the angle of the plate 16 and may be firmly secured in position by simply screwing up on the handle 10 until its threaded inner end or screw 13 engages and presses against the inner side" of the plate 16 and forces said plate outwardly in a direction from the plate 15 to an adequate degree to effect the pinching of. the ends of the blade 12 a ainst the inner surfaces of the lips20. Vhen the blade has been thus secured in position, the .safetyrazor is ready for use, all of its parts being firmly bound together by the pressure of the screw 13 against the inner face of the plate 16 and the resistance offered by the lips 20 against the outer face of the ends of the blade. The blade when secured in position is perfectly flat, even though it is only held 'at its ends between the shoulders 21 and lips 20, since the pressure of the screw 13 is against the plate 16 and only acts on the blade through the shoulders at the ends of said plate 16. The blade acts as a key between the lips 20 on the back or base-plate 15 and the. freely hinged plate 16 and prevents said plate 16 from moving unduly outwardlywhen the parts of the device are tightened up by the handle.

When it is desired to remove the blade from the frame holding it, the handle 10 will be slightly unscrewed so as to relieve its pressure from the inner face of the plate 16, and thereupon the blade may he slipped outwardly from below the li s 20 and in that way removed from the rame. Upon the removal of the blade 12 from the holding-frame 11, the plate 16 is left free to be swung on its hinges or pivot pins 19 outwardly from operative relation to the back or base-plate 15, so as to thereby fully expose the'surfaees of both plates and enable said plates to be very readily cleaned. The plate 16 in length in line with the lips 20 is shorter than the open space between the facing edges of said lips and hence may when desired be swung from over the baseplate and to the full outward position in which it is shown in Fig. 6.

It will thus be seen that the safety razor of my invention is composed of but a few simple parts, capable of ready manufacture, and that the blade may with great convenience be applied to and removed from the holding-frame, which after the blade has been removed, is free to become exposed on all sides so as to be capable of being readily cleaned.

I do not limit myselfto the precise details hereinbefore described otherwise than may be indicated in the claims.

WVhat I claim asmy invent on and desire to secure by Letters. Patent, is:
