Improvements on MACHINERY FOR FILING
Year: 1870

page_text: LETTERS PATENT to James Willis Dixon, jun", of Oakfield House,
Sheffield, and John Bates, of 87, Portland Street, Sheffield, for the
Invention of "Improvements on MACHINERY FOR FILING "
PROVISIONAL SPECIFICATION left by the said James Willis Dixon
and John Bates at the Office of the Commissioners of Patents, with
their Petition, on the 11th February 1870.
We, JAMES. WILLIS DIXON, jun"., of Oakfield House, Sheffield, and
JOHN. BATES, of 87, Portland Street, Sheffield, do hereby declaro the
nature of the said: Invention for "IMPROVEMENTS IN MACHINERY FOR
FILING," to be as follows:-
:
1:
In constructing machinery for filing according to this Invention: tho
file is carried in a holder to which a reciprocating to-and-fro motion is
-imparted, the article to be filed is supported on a bed and is brought up
to the file at the time when the file commences to make its forward
stroke, and is lowered away from the file when the file has completed its

page_text: stroke and is being drawn-backwards. This I prefer to effect by giving
the to-and-fro motion to the file holder by a connecting rod and crank,
and by governing the rising and falling of the bed upon which the
work is supported by an eccentric on the crank shaft. The eccentric
rod is for this purpose coupled to a lever to which a stem carrying the
bed is also connected. A strip of india-rubber or elastic material is laid
upon the bed, and above this packing pieces of wood or other material
are placed for the work to rest on, and the work is thus adjusted to the
proper height for the file to act upon.it. The upright stem can also be
shortened or lengthened to give a further power of adjustment.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Willis Dixon and John Bates in the Great
Seal Patent Office on the 10th August 1870.
TO ALL TO. WHOM THESE PRESENTS SHALL COME, we, JAMES
WILLIS DIXON, junior, of Oakfield House, Sheffield, and JoHN BATES,
of 87, Portland Street, Sheffield, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent; bearing date the Eleventh day of February, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give and grant'
unto us, the said James Willis Dixon, junior, and John Bates, Her
special licence, that we, the said James Willis Dixon, junior, and John
Bates, our executors, administrators, and assigns, or such others as we,
the, said James Willis Dixon, junior, and John Bates, our exccutors,
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 MACHINERY
FOR FILING," upon the condition (amongst others) that we, the said
James Willis Dixon, junior, and John Bates, our executors or adminis-
trators, 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 par-
ticularly describe and ascertain the nature of the said Invention, and
what manner the same was to be performed, and cause the same to
-
-

next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Willis Dixon, on behalf
of myself and the said John Bates, do hereby declare the nature of
the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following
statement thereof, that is to say :—
In constructing machinery for filing according to this Invention the
file is carried in a holder to which a reciprocating to-and-fro motion is
imparted, the article to be filed is supported on a bed and is brought up
to the file at the time when the file commences to make its forward
stroke, and is lowered away from the file when the file has completed_
its stroke and is being drawn backwards. This we prefer to effect by
giving the to-and-fro motion to the file holder by a connecting rod and
crank, and by governing the rising and falling of the bed upon which.
the work is supported by an eccentric on the crank shaft. The eccentric
rod is for this purpose coupled to a lever to which a stem carrying the
bed is also connected. A strip of india-rubber or elastic material is
laid upon the bed, and above this packing pieces of wood or other
O material are placed for the work to rest on, and the work is thus
adjusted to the proper height for the file to act upon it.
Tho upright
stem can also be shortened or lengthened to give a further power of
adjustment.
In order that our said Invention may be most fully understood and

page_text: slotted and the position of the pin c¹ upon it is adjustable, so that the
stroke of the slide e may be varied; f is a file which is clamped to
the slide. The work is secured upon the table g fixed on the top of the
slide / which is able to move vertically in guides on the frame. The
slide receives its motion from a stem i; it has an adjusting screw at "
resting on the top of the stem and connected with it, but so that it can
turn freely. The stem is jointed to an arm fixed on an axis k, which
also has fixed upon it the arm ; this arm at its outer end has the
stem / jointed to it; it passes up through a guide and carries a friction
pulley bearing with the weight of the table and the work upon it on
the cam m upon the main axis b. This cam is so cut as during the
backward stroke to allow the table with the work upon it to fall away
a short distance from the file, and during the forward stroke to hold up
the table so that the file may act on the work and reduce the parts
thus submitted to its action. The guides in which the slide / works aro
adjustable on the frame, so that when required the surface of the table
may be set at an inclination to that of the file.
Having thus described the nature of our said Invention, and the
manner of performing the same, we would have it understood that we
claim, the construction of machinery for filing with a reciprocating filc
and a table for carrying the work, which by an automatic movement is
brought in contact with the file at cach forward stroke and relieved
from it at each backward stroke, substantially as described.
In witness whereof, I, the said James Willis Dixon, have here-
unto set my hand and scal, this Seventh day of August, in the
year of our Lord One thousand eight hundred and seventy.
