Improvements relating to Razors.
I, JOHN GERHARD BESTGEN, of Somerville in the County of Middlesex, State.
of Massachusetts, United States of America, Manufacturer of Cutlery, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The blades of razors are ordinarily pivoted in the handle by a smooth pivot
headed at its ends. The handles being commonly constructed of bone, ivory or
similar material are frequently broken in thus riveting the pivot. Moreover,
should the pivot opening in the blade wear slightly from use, the blade does not fit
with sufficient accuracy to prevent its sharpened edge from engaging the side of
the handle in closing the same. To remedy this it is customary to bend the pivot
by which process the handles are frequently split or broken.
My invention is designed especially to overcome these objections and furnish a
pivot mechanism whereby the user can readily remount the razor blade in a new
handle when the original becomes broken and can adjust the blade therein so that
its sharpened edge will not engage the edge of the handle when closing it.
In the accompanying drawing
Figure 1 is a side elevation of a razor provided with my improved pivot.
Figure 2 an enlarged elevation of the pivot enlarged showing the washer.
Figure 3 a transverse section enlarged taken on line a, a in Figure 1, and
Figure 4 an enlarged elevation of the wrench-tool.
Like letters and figures of reference indicate corresponding parts in the different.
figures of the drawing.
A represents the blade and B the handle which consists in the ordinary manner
of two plates f, of horn or similar material connected at one end by a rivet g.
The pivot C comprises a screw-bolt having an oval head h, and a screw-threaded
shank. This bolt is inserted in the pivot opening of the handle and through the
pivot opening of the blade-tang in the usual manner.
A nut k similar in shape to the bolt-head is turned onto the outer end of said bolt.
Said nut has tool-openings m for receiving the arms of the tool D whereby it is
turned onto the bolt shank.
The blade plays freely on the bolt and the tension of the handles against said
blade may be readily taken up by the nut k.
To obviate the necessity of bending the pivot to so adjust it that its edge will
not engage the handle plates I turn a nut p onto the bolt shank, said nut having a
vertical tool-hole y whereby it can be set up when the parts are joined.
One or more of these nut-shaped washers can be disposed on the bolt between the
handle-plates to engage the blade-tang.
By their use the blade can readily be adjusted for the purpose specified without
bending the pivot in a manner that will be understood without a more explicit
description.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :-
First. The combination in a razor of a handle with a bolt blade pivoted therein,
said pivot comprising a screw-bolt passing through the handle, and blade-tang and
secured by a nut turned thereon substantially as described.
Second. A pivot for razor blades comprising a screw-bolt passing through the

page_text: razor handle and upon which the blade plays loosely and a nut turned onto said
bolt whereby the tension of said handle against the blade may be regulated.
Third. The combination in a razor of a handle with a screw-bolt passing
laterally therethrough, a blade pivoted to swing freely on said bolt, a washer
mounted on the bolt between said blade and one of the handle sides, and a mut
turned onto the outer end of said bolt, substantially as described.
Fourth. The combination of the handle B with the pivot C having the threaded
shank i, the blade A pivoted to swing on said shank. the nut k, turned onto said
shank and the screw-washer pon said shank between the blade and handle sub-
stantially as and for the purpose set forth.
Dated this 20th day of September 1892.
