page_text: I, WILLIAM GEORGE ROWE of Marazion in the County of Cornwall Builder, do
hereby declare the nature of this invention to be as follows:-
My improvements relate to planes having parallel fence plates or guide pieces
fixed on arms or guide stems projecting at right angles from the body of the plane.
These projecting arms are made of wood and are fitted tightly to apertures in
the body of the plane, through which they are intended to slide, so as to adjust the
space between the fence and the plane according to the requirements of the work.
These arms are fixed by wedges and are liable to swell in damp weather and are
then extremely difficult to adjust accurately to their proper parallel position,
while in dry weather they sometimes shrink and slide so easily that it is a.
troublesome operation to fix them correctly and firmly.
In my improved planes, I cause the guide stems to slide through metal collars
placed in the body of the plane. At one end of these guide stems the fence-plate
is attached as usual. At the other end I fix a metal cross bar, connecting the two
ends of the said stems together.
In the centre of this cross-bar, I place a metal thumbscrew of about half an inch
in diameter and of considerable length. This screw works in a fixed nut, placed
in the body of the plane, in such a way that when turned in one direction, it
draws the fence plate nearer to the plane and when turned in the other direction
it thrusts it farther off. By means of this adjusting screw the operator is enabled to
adjust the several connected parts of the plane with the greatest ease and nicety.
By preference I construct the said guide stems of metal either solid or hollow.
I also attach a moveable nut or other kind of clamp to the said centre screw when
desired so as to fix it firmly at any required distance. The aforesaid cross-bar and
fence-plate are so fitted to the guide stems by means of screws or steel-pins as to
be readily removed when required.
Thumb-screws can also be inserted in the body of the plane for the purpose of
wedging the guide stems and preventing their slipping when the plane is at work.

page_text: I, WILLIAM GEORGE ROWE, of Marazion, county of Cornwall, Builder, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement -
My improvements relate to Plough and Sashfillister and similar planes having
parallel fence plates or guide pieces fixed on arms or guide stems projecting at
right angles from the body of the plane.
These projecting arms are heretofore made of wood and are fitted tightly to
apertures in the body of the plane, through which they are intended to slide, so
as to adjust the space between the fence and the plane according to the require-
ments of the work. These arms are fixed by wedges and are liable to swell
in damp weather, and are then extremely difficult to adjust accurately to their
proper parallel position, while in dry weather they sometimes shrink and slide so
easily that it is a troublesome operation.to fix them correctly and firmly.
In my improved planes in order to avoid the above-named defects, I cause the
guide stems to slide through metal sockets or collars placed in the body of the
plane. At one end of these guide stems the fence-plate is attached as usual. At
the other end I fix a metal cross bar, connecting the two ends of the said stems
together.
In the centre of this cross bar, I place a metal thumbscrew of about half an inch
in diameter and of considerable length. This screw works in a fixed nut, placed
in the body of the plane, in such a way that when turned in one direction, it
draws the fence plate nearer to the plane and when turned in the other direction
it thrusts it farther off. By means of this adjusting screw and the metal sockets,
the operator is enabled to adjust the several connected parts of the plane with the
greatest ease and nicety.
By preference I construct the said guide stems of metal either solid or hollow.
I also attach a moveable lock-nut as a kind of clamp to the said centre screw
when desired so as to fix it firmly at any required distance.
The aforesaid cross bar and fence plate are so fitted to the guide stems by
means of screws or steel pins as to be readily removed when required.

page_text: Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
1st. The method of adjusting the fence-plate of planes by means of a cross
bar, screw and nut, and locknut, as herein described and set forth.
2nd. The use of hollow or solid guide stems together with metal sockets for
the same as herein described.
