PHILIP II. UNSINGER, OF GENEVA, NEW YORK, ASS-IGNOR TO GENEVA CUTLERY CORPORATION 0F GENEVA, NEW YORK, A CORPORATION OF NEW YORK. I

SAFETY-RAZOR.

Application filed March 24, 1919.

To @ZZ whom t may concer/n.'

Be it known that I, PHrLrr H. NSINGER, a citizen of the United States of America, and resident of Geneva, in the county of Ontario, in theV State of New York, have invented new and useful Improvements in Safety-Razors, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in safety razors.

An object of the invention is to produce a safety razor of relatively simple construction and mechanical operation in which there is practically no danger of the user cutting himself in assembling or disassembling the parts. .Y

Another object relates to the efficient an positive nature of the holding .or locking means for securing the parts in position for use.

A further object relates to the production of a combined plain and toothed guard in which the plain guard or guard bar is positioned in advance of the teeth and from which the teeth project somewhat upwardly and rearwardly toward the blade to. have a smoothing rather than a digging effect. The teeth terminate beneath lthe blade and are of such a length as to insure freedom of the beard from being forcedagainst the face both before and duringcutting. The guard bar preceding the guard teeth avoids sharp corners coming in contact with the face and wipes atleast a portion of the lather from the face.

A further advantage resides in the ease and rapidity with which the parts may be assembled for use and disassembled as for cleaning or packing or other purposes.

The other objects and advantages relate to the details of construction as will more fully appear from the following description taken in connection with the accompanying drawings in which Figure l is a perspective view of the safety razor taken from the rear.

Fig. 2 is a section on line Qf-2, Fig. 1.

Fig. 3 is a section on line 3-3, Fig. l.

Fig. 4 is a section on line 1 -4, Fig. 2.

The razor as shown comprises a base plate --1- preferably formed of sheet metal having its front portion bent downwardly from the body of the plate and preferably lying Specification of Letters Patent.

Serial No. 284,749.

to constitute when formed as hereinafter described a guard bar and a series of upwardly and rearwardly extending guard teeth. For this purpose the plate has a portion cut away to form an elongated opening n2- bordered by relatively narrow sidewalls --3- and a narrow integral bar -4` constitutng the guard bar of the razor. A series of guard teeth -5- project into the opening -2- and when the front portion of the plate -1- is bent downwardly about an axes extending through the intermediate portions of the side walls K3- these teeth extend vpreferably forwardly and rearwardly toward a blade -6- when properly-seated upon the base -1-. The opening -2 extends some distance tok the rear ofthe front at an obtuse angle with the body of the plate i edge of yblade and as vstated the teeth -5- terminate beneath the blade leaving a free passagebeneathl the blade `for lather,

' hair, etc., the 'front edge of the blade at the side portions being supported by side walls 3 and preferably these walls are provided with stops -7- to properly limit and position the blade. Tbesestops -7- may be formed in any suitable manner las by punching up parts of the plate f1- or otherwise. The blade-G- is held in place Lupon the base f lby a clamping member formed'upon opposite' edges of the `rbase l-. The endV parts -10 may preferably be shaped as shown, the rear part being substantially circular in form and the remaining portion of said part tapering forwardly and adapted to lie outside ofthe opposite edges of base -1- to inclose the blade except as to its projecting front edge portion. The rear portion -13 of the clamping member -8 is preferably bent in substantially arcuate form to conform to the shape of the rear portion of parts 10- and forms a receptacle adapted to receive and hold the blade when the clamping member is rocked about the plate -'lto its bent position. For the purpose of locking or holding the clamping member in proper position relative to the base -1- to tightly grip the blade and hold it rigidly in position for use the rear portion -13- is provided with a central flange 1% which may preferably be a symmetrical condition of the said arcuate portion and extends toward the rear face of the base -I and the base is provided with a cut out portion -l5 forming a recess through which the flange 1-l` moves when the clamping member is rocked about the base A1--. Y

It will' be understood that by exerting pressure on flange -l4f-- to force it rearwardly away from the base -1 the clamping member -8- will be rocked about the base -1- until its front edge tightly grips the blade 6* interposed between the clamping plate and the base and as this member is formed of sheet metal of a more or less resilient nature the blade will be tightly and rigidly gripped with a spring tension thus permitting slight variation in the size and relation of the parts without affecting their efficient operation. For accomplishing this purpose in a preferred manner the handle -16- may be secured to the base --1-n for rotary movement about an axis substantially perpendicular to the` base and this may be accomplished by forming the handle with a somewhat enlarged head -17- having a recess 1S-- for engagement with screw 19- extending through the base 1 and preferably having its head countersunlr therein and constituting such axis. The head l7-` is provided with a projecting lug 20- or member which may as shown be tapered longitudinally and laterally and so positioned that upon rotary movement of the handle -16- this lug is forced beneath the flange -14- to press the same rearwardly and effect the operation heretofore described. The lug -20-- may be of somewhat angular or inverted V-shape and the flange lll-- may be provided with` a small recess adapted to engage the peak of the lug when the parts are properly positioned to frictionally roclr the same.

The handle -16- may if desired be formed in sections in the usual manner and may be shaped in desired form to effect the most efficient operation of the blade -6- when positioned between the base and the clamping member.

Although I have shown and described a specific construction, form and relation of the parts as illustrative of a perhaps preferred embodiment of my invention, I do not desire to limit myself to the same as various changes, modifications and substitutions may be made in the detail of construction, form, arrangementand operation without departing from the invention as stated herewith in the appended claims.

What I claim is 1. A. razor comprising a base7 a clamping member pivoted tothe base and embodying a flangeextending from the rear of the fulcrum to a position at the opposite side of lthe base and in front of the said fulcrum and a member movably mounted on the base and engaging the said flange in front of the said fulcrum and acting to hold the clamping member in blade gripping position.

2. A razor comprising a base, a clamping member pivoted to the rear portion of the base and embodying a flange extending from the rear of the fulcrum to a position at the opposite side of the base and in front of the said fulcrum, a member movably mounted on the base and engaging the said flange in front of the said fulcrum and interlocking parts on the said member and flange.

3. A razor comprising a base, a clamping member pivoted to the base and embodying a fiange extending from the rear of the fulcrum to a position at the opposite side of the base and in front of the said fulcrum, a member' movably mounted on the base and engaging the said flange in front of the said fulcrum and acting to hold the clamping member in blade gripping position and a handle secured to the base and actuating the said member.

In witness whereof I have hereunto set my hand this 17th day of March, 1919.

PHILIP I-I. UNSINGER.
