To all whom it may concern:
Be it known that I, Alexander B. Lauterbach, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented an Improvement in Safety Razors, of which the following is a specification.
This invention relates to safety razors and it has for one of its objects to provide an improved universal joint between the head which supports and carries the blade and the handle whereby the head and the blade carried thereby may be adjusted readily to any desired angle with respect to the handle.
A further object of the invention is to provide means whereby after the blade has been secured to the head a closer shave may be effected by the employment or use of one cutting edge thereof than if the other edge or one of the other edges were employed or used.
With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the construction as herein disclosed may be made within the scope of the claims without departing from the invention.
In order that the invention may be readily understood and its practical advantages fully appreciated, reference may be had to the accompanying drawing forming a part of this specification and in which—
Referring to the drawing:
The head portion of the structure comprises an inverted cone-shaped three sided member
The upper edges of the sides of the part
The central portion of the guard plate
Although I have described the top end portion of the part
1. In a safety razor, the combination of a handle having a dome-shaped hollow upper end, a head comprising sides and a closed end portion, the said end portion being curved inwardly to form a concave surface adapted to hug the convex outer surface of the dome-shaped end of the said handle, and yielding means connected with said head and engaging said handle for connecting said head to the said handle.
2. In a safety razor, the combination of a handle having a dome-shaped hollow upper end provided with a relatively large opening therethrough, a head provided at its inner end with a portion adapted to hug the outer surface of the said dome-shaped end, said head having a projection which extends through the said opening, and a spring washer secured to the inner end of said projection, the said washer being of a shape to hug against the inner surface of the dome-shaped end of said handle.
3. In a safety razor, the combination of a handle the top hollow end of which is spherical, said end being provided with a relatively large opening, a head the bottom end of which is concaved to form spherical surface which hugs against the outer spherical surface of the end of said handle, a bolt projecting from the end of said head through the opening in the said handle, and a spherical spring washer secured to the lower end of said bolt, the outer spherical surface of which hugs against the inner spherical surface of the end of said handle.
4. In a safety razor, the combination of a hollow handle the top end of which terminates in a spherical portion having a centrally arranged relatively large opening therethrough, a head comprising an inverted frustum of a pyramid constructed of metal, the lower end of which is projected upwardly to form a concaved spherical surface which hugs against the outer convex spherical surface of the end of said handle, a headed bolt extending through the end of said head, and a spring washer secured to the lower end of said bolt, the portion of the top end of the said handle surrounding the opening therethrough being clamped between the said washer and the opposing lower end of the said head.
5. In a safety razor, in combination, a handle terminating at its top end in a hollow semi-spherical portion having a relatively large circular opening therethrough, a head comprising an inverted truncated cone-shaped portion, the bottom of which is projected upwardly to form a concaved spherical surface which is adapted to fit against and hug the outer convex spherical surface of the top end of said handle, a bolt provided with a relatively wide plate-like flange which is curved to fit the convex upper surface of the lower end of the said inverted truncated cone-shaped portion, the said bolt projecting through the opening in the top end of said handle, and a semi-spherical spring washer situated inside of the hollow semi-spherical end portion of said handle, said washer being secured to the lower end of the said bolt and being adapted to press yieldingly against the inner surface of the semi-spherical end portion of said handle.
6. A safety razor comprising a head portion including a guard plate having elevated portions adjacent its outer edges, a razor blade resting upon said portions, said guard and said blade being provided with alined centrally arranged polygonal openings, a holder for securing said blade upon the said head, said holder having a stud of polygonal shape in cross section projecting downwardly therefrom through said opening, said stud being provided with a reduced headed stud portion at its lower end, and an arm pivotally connected to the under side of the said guard plate and adapted to be moved into engagement with the said headed stud to retain the said holder and the said razor blade in position upon the said head.
In testimony that I claim the foregoing as my invention I have hereunto signed my name this 29th day of September, A. D., 1920.
