PROVISIONAL SPECIFICATION.
Improvements in Machines or Apparatus for Sharpening or Stropping
Razors and such like.
HERBERT AKROYD STUART Bletchley Iron & Tin Plate Works, Bletchley in
the County of Bucks, Mechanical Engineer, do hereby declare the nature of this
invention to be as follows :-
This Invention relates to improvements in Machines or apparatus for sharpening
or stropping Razors or their equivalents. In carrying the said invention into practice
a suitable framework is constructed having one or more pulleys or supports to carry
or guide the leather or prepared canvas or other suitable substance used to sharpen
the razors and which is hereinafter termed the Band, and such bands may be arranged
either in a strip or as an endless band.
The said band is reciprocated either in a straight, angular, or curved direction.
In conjunction with the said pulleys or guides is a suitably shaped hinged or
swivelled bracket to hold the razor or its equivalent and such bracket may be either
oscillated or actuated direct by the band, or it may be actuated in conjunction with
one of the rollers or supports, or it may form portion of one of the said rollers or
supports.
The said swivelled bracket is employed to hold and place the razors at s.itable
angles so that each side or face of the razor is alternately rubbed by the band in
sharpening them. The desired motion to the bracket is obtained as before
described.
It will easily be seen that by the arrangement of the band and pulleys or
supports which guide the band, more than one razor may be sharpened at the same
time.

Improvements in Machines or Apparatus for Sharpening or Stropping
Razors and such like.
HERBERT AKROYD STUART Bletchley Iron and Tin Plate Works, Bletchley in the
County of Buckinghamshire, Mechanical Engineer, 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 :-
This invention relates to improvements in machines or apparatus for sharpening
or stropping razors or their equivalents.
In carrying the said invention into practice a suitable framework is constructed
having one or more pulleys or supports to carry or guide the leather or prepared
canvas or other suitable substance used to sharpen the razors and which is hereinafter
termed the band and such bands may be arranged either in a strip or as an endless
band. The said band is reciprocated either in a straight, angular or curved direction.
In conjunction with the said pulleys or guides is a suitably shaped hinged or swivelled
bracket to hold the razor or its equivalent and such bracket may be either oscillated
or actuated direct by the band or it may be actuated in conjunction with one of the
rollers or supports or it may form portion of the said rollers or supports. The said
swivelled bracket is employed to hold and place the razor at suitable angles so that
each side or face of the razor is alternately rubbed by the band in sharpening it. The
desired motion to the bracket is obtained as before described. It will easily be seen
that by the arrangement of the band and pulleys or supports which guide the band
more than one razor may be sharpened at the same time.

page_text: In order that my said invention may be more fully understood annexed hereto is
a sheet of drawings wherein similar letters of reference refer to similar parts in all
Figures..
Fig. 1. is a longitudinal side elevation of a razor stropping machine... Fig. 2 is plan
of same. Fig. 3 is a vertical section at 1. 2. showing arrangement of band in
conjunction with the rollers and razor bracket.
.
A is part of the machine frame formed into a cramp to secure the machine to a
table or other support with the thumb screw B. Rods C. D are screwed into the
frame whereon are swivelled respectively the links E F and the razor bracket G.
The links are for the purpose of carrying the rollers or pulleys H. I. which rollers
revolve on their respective pin or rod J. K. which pins secure the two links E. F
together. On the rod D. fixed to the machine frame is swivelled the razor bracket G.
the razor being firmly secured therein with the set-screw L. On the rod D. is also
arranged the flanged roller M. which while rotating may also be moved laterally
along the said rod by which means I can use a narrow band instead of one the full
breadth of the razor blade. In some instances I prefer to thread tho said rod D.
and also the flanged roller to suit same so that by rotating it, it automatically
screws itself along to produce its lateral motion. The action of the machine is thus,
supposing the links E. F. are in a horizontal position or that the centres of the
rollers H. I. are in a line with the lino 3. 4. which is their normal position kept
'there by the springs N. O. The user takes hold of each end of the band then by
pulling the left hand one the links E. F. are placed at an angle as shewn in illus-
tration Fig. 3. At the same time the razor and razor bracket are placed at an
angle by means of the spring O. which places the razor blade on to the band P. and
the band continuing motion rubs against the face of the razor Q. 'It will be seen that
any further movement of the top links simply stretches the spring O. and presses the
razor harder against the band. A stop R. is placed to prevent the links from getting
too great an angle. In order to strop the other side or face of the razor the right
hand end is pulled which places the links E. F to the opposite angle and at the same
time the razor and razor bracket are also placed at the opposite anglo by the action
of the spring N. this places the razor on to the opposito side of the band as shown
in dotted lines. It will easily be understood that by reciprocating the band in first
the one direction and then in the opposite a keen edge may quickly be put on to the
razor.
"Having now particularly described the nature of this invention and in what
manner the same may be performed. I wish it to' he particularly understood that
I do not confine myself to the exact configuration of the machine as an endless band
may be employed and motion given to it either.in a rotary or semi-rotary direction, but
what I claim as novel and original is
1st. In razor stropping machines, reciprocating the band or strap or its equivalent
for the purpose and substantially as herein described and set forth.
2nd. In razor stropping machines automatically actuating the razor bracket, (and
thus the razor) by means of the band or strap and the springs N. O. as herein described
and set forth.
3rd. In razor stropping machines the arrangement and combination of the band
or strap and rollers and razor bracket as illustrated in the annexed drawings for the
purpose and substantially as herein described and set forth.
4th. In razor stropping machines the arrangement application and combination of
the general arrangement of the parts herein 'described for the purposes and substan-
'tially as herein 'described and set forth.
