Year: 1859

page_text: LETTERS PATENT to Martin and Alexander Samuelson,, both of Scott
Street Foundry, Hull, in the County of York, Engineers and Iron Ship
Builders for the Invention of "IMPROVEMENTS IN PLANING, SLOTTING,
AND GROOVING MACHINES."
Sealed the 2nd March 1860, and dated the 30th September 1859.
PROVISIONAL SPECIFICATION left by the said Martin and Alexander
Samuelson at the Office of the Commissioners of Patents, with their"
Petition, on the 30th September 1859.
We, MARTIN and ALEXANDER SAMUELSON, both of Scott Street Foundry,.
Hull, in the County of York, Engineers and Iron Ship Builders, do hereby.
declare the nature of the Invention for "IMPROVEMENTS IN PLANING, SLOTTING,
AND GROOVING MACHINES," to be as follows:-
This Invention has for its object improvements in planing, slotting, and
grooving machines. For this purpose when making machines for planing,
slotting, or grooving heavy castings, we employ a framing which is to be bolted
to the casting to be planed, slotted, or grooved; in the upper part of this frame
a bar slides, to which a to-and-fro motion is given by means of a screw;
this screw is cut at one end of an axis, which turns in bearings carried by a
standard or projection from the framing; the axis carries one fixed and two
loose pullies, and is caused, to rotate in.one or other direction alternately by

page_text: two driving bands, the one direct and the other crossed. The screw being
thus caused to revolve, draws the bar to-and-fro by working with a female
screw cut on the interior of a passage formed in the bar. On the opposite
end of the bar to that into which the screw enters; dovetailed guides are formed,
on which a slide works in a direction at right angles to the length of the
bar; this slide carries the cutting tool, and is (when the machine is being
used for planing,) traversed a distance sideways after each movement of the
bar by means of a screw, so that the tool may pass over a fresh portion of the
surface, as in ordinary planing machines; the tool is also capable of being
raised or lowered on the slide by means of another screw, so that the tool may
be caused to take a greater or less depth of cut, or to form a groove or slot
in the casting. In place of giving a to-and-fro motion to the sliding bar by
means of a screw, as above described, motion may be communicated to it by
means of a worm wheel, or by other suitable means.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Martin and Alexander Samuelson in the Great Seal Patent
Office on the 30th March 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, MARTIN
and ALEXANDER SAMUELSON, both of Scott Street Foundry, Hull, in the County
of York, Engineers and Iron Ship Builders, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of September, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did for Herself, Her heirs and successors, give and grant unto us, the
said Martin and Alexander Samuelson, Her special licence that we, the said
Martin and Alexander Samuelson, our executors, administrators, and assigns,
or such others as we, the said. Martin and Alexander Samuelson, our exe-
cutors, administrators, and assigns, should at any time agree with, and no
others, from time to time; and at all times thereafter, during the term therein
expressed, should and lawfully might make, use, exercise and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN PLANING, SLOTTING, AND GROOVING
MACHINES," upon the condition (amongst others) that we, the said Martin
and Alexander Samuelson, our executors or administrators, by an instrument
in writing under our or their hands and seals, or under the hand and seal of
one of us or them, should particularly describe and ascertain the nature of the

page_text: said Invention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Alexander Samuelson, on behalf of
myself and the said Martin Samuelson, do hereby declare the nature of the said.
Invention, and in what manner the same is to be performed, to be. par-
ticularly described and ascertained in and by the following statement-thereof,.
that is to say:-
This Invention has for its object improvements in planing, slotting, and..
grooving machines. For this purpose when making machines for planing,
slotting, or grooving heavy castings, we employ a framing-which is to be bolted
to the casting to be planed, slotted, or grooved. In the upper part of this
frame a bar slides, to which a to-and-fro motion is given by means of-a-screw-;
this screw is cut at one end of an axis, which turns in bearings carried-by-a
standard or projection from the framing; the axis carries one fixed-and-two
loose pullies, and is caused to rotate in one or other direction alternately by
two driving bands, the one direct and the other crossed. The screw being
thus caused to revolve, draws the bar to and fro by working with a female
screw cut on the interior of a passage formed in the bar. On the opposite..
end of the bar to that into which the screw enters dovetailed guides are.
formed, on which a slide works in a direction at right angles to the length of..
the bar.; this slide carries the cutting tool, and is (when the machine-is being
used for planing), traversed a distance -sideways after each movement of the
bar by means of a screw, so that the tool may pass over a fresh-portion of the
surface as in ordinary planing machines; the tool is also capable of being raised
or lowered on the slide by means of another screw, so that the tool may be▸
caused to take a greater or less depth of cut, or to form, a groove or slot in
the casting. In place of giving a- to-and-fro motion to the sliding bar by
means of a screw as above described, motion may be communicated to it by
means of a worm wheel, or by other suitable means.
And in order that our Invention may be most fully understood and readily
carried into effect, we will proceed--to describe-the-Drawings-hereunto™
annexed.
DESCRIPTION OF THE DRAWINGS.

page_text: be planed, slotted, or grooved; 6 is a bar of square section, which is capable
of being moved to and fro through a suitable passage formed for it in the
framing. The bar at its back end has a passage bored into it, in which a
screw thread is cut; into this female screw a male screw on one end of the
axis c works; this axis turns in a bearing carried by the standard a' from the
framing a; on the opposite end of the axis to that on which the screw thread
is cut there are two loose pullies c', c', and one fast pulley c, of less width
than the loose pullies. The axis c may be caused to rotate in one or other
direction by one or other of two driving bands (one direct and the other
crossed), being moved on to the fast pulley c³, and by this means the bar b
may be moved backwards and forwards, and by reason of the loose pullies being
of greater width than the fast pulley, both the bands may be retained on the
loose pullies, so that no motion will be given to the bar 6; d is a slide which
is capable of being moved to and fro in a direction at right angles to the bar b
in doetailed guides formed on the opposite end of the bar to that into which
the screw on the axis centers. This movement is given to the slide by a
screw turned by the handle d'. The cutting tool is carried by a slide e, which
is capable of being moved on dovetail guides on the slide d, to and fro in a
direction at right angles to the movement of the slide d. This movement is
given to the slide e by a screw turned by the handle e¹. By this means when
the machine is being used for planing, the slide d may be moved a distance
sideways after each movement of the bar by turning the handle d', so that the
tool may pass over a fresh portion of the surface to be planed, as in ordinary
planing machines the tool may also be made to take a greater or less depth of
cut by turning the handle e', and it may also be caused to form a groove
or slot.
In witness whereof, I, the said Alexander Samuelson, have hereunto
set my hand and seal, this Twenty-eighth day of March, in the year
of our Lord One thousand eight hundred and sixty.
