IMPROVEMENTS IN MODES OF APPLYING LAMPS TO SEWING MACHINES AND OTHER ARTICLES, AND IN APPARATUR FOR EFFECTING THE SAME
Year: 1875

page_text: LETTERS PATENT to Frederick Macklin Willson, of Liverpool, in the
County of Lancaster, for the Invention of “IMPROVEMENTS IN MODES
OF APPLYING LAMPS TO SEWING MACHINES AND OTHER ARTICLES, AND IN
APPARATUR FOR EFFECTING THE SAME,
"
Sealed the 26th April 1876, and dated the 27th October 1875.
PROVISIONAL SPECIFICATION left by the said Frederick Macklin
Willson at the Office of the Commissioners of Patents, with his
Petition, on the 27th October 1875.
I, FREDERICK MACKLIN WILLSON, of Liverpool, in the County of
Lancaster, do hereby declare the nature of the said Invention for "Iм-
PROVEMENTS IN MODES OF APPLYING LAMPS TO SEWING MACHINES AND OTHER .
ARTICLES, AND IN APPARATUS FOR EFFECTING THE SAME," to be as follows: -
In working a sewing machine by artificial light it is necessary to
have the lamp near the object and yet not in the way. In different
operations too the best position for a lamp varies. If the lamp is
placed on the sewing machine table the tremor caused by the instrument
is apt to gradually shake it to the edge of the table till it falls off.

page_text: Several disasterous fires have been occasioned by this circumstance.
Again, it frequently happens that the best position for the lamp is
almost immediately over the part where the material to be sewed would
naturally lic, and the work has to be inconveniently pressed aside for
this purpose. It is to obviate all these difficulties that this my Inven-
tion is designed; it consists,-
1st. Of a hollow socket, having a rim on one end and a set screw
through it at or near the middle. This socket is let into the sewing
machine table, the rim only appearing flush with the upper surface of
the table, the socket hanging perpendicularly below. Or the socket
may have a bracket attached to it for clamping it to the table instead
of being let into it. A hollow pillar is made to slide within the socket,
and is held in its place at any height by means of the set screw.
A metallic bracket or lamp holder is constructed with an arm or shank,
which is jointed to a link or series of links (having free lateral but little
or no vertical play). The furthest of these links is jointed in a similar
manner to the top of the hollow pillar. The latter can be made of one
or more tubes and a cylinder if desired, telescoping into each other,
but I prefer it in a single piece. The metallic bracket or lamp holder
aforesaid usually consists of a ring or socket for holding a lamp, attached
to which is another socket or other fixture for holding a reflector. The
latter is usually arranged so as to be adjustable at pleasure for throwing
the light in any desired direction.
SPECIFICATION filed in pursuance of the conditions of the Letters
Patent, and of an Order of the Lord Chancellor, by the said Frederick 2
Macklin Willson in the Great Seal Patent Office on the 26th May
1876.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
MACKLIN WILLSON, of Liverpool, in the, County of Lancaster, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of October, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Frederick Macklin Willson,

page_text: Her special licence, that I, the said Frederick Macklin Willson, my
executors, administrators, and assigns, or such others as I, the said
Frederick Macklin Willson, my 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, usc, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN MODES OF APPLYING LAMPS TO
SEWING MACHINES AND OTHER ARTICLES, AND IN APPARATUS FOR EFFECTING THE
SAME," upon the condition (amongst others) that I, the said Frederick
Macklin Willson, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and scals, should
particularly describe and ascertain the nature of the 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 Lotters Patent.
NOW KNOW YE, that I, the said Frederick Macklin Willson, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, reference being had to
the accompanying Drawings and to the figures and letters of reference
marked thereon :-
In working a sewing machine by artificial light it is necessary to
have the lamp near the object and yet not in the way. In different
operations too the best position for a lamp varies. If the lamp is
placed on the sewing machine table the tremor caused by the instru-
ment is apt to gradually shake it to the edge of the table till it falls off.
Several disastrous fires have been occasioned by the circumstance.
Again, it frequently happens that the best position for the lamp is
almost immediately over the part where the material to be sewed would
naturally be, and the work has to be inconveniently pressed aside for
this purpose. It is to obviate all these difficulties that this my Inven-
tion is designed; it consists,-
1st. Of a hollow socket A having a rim B on one end and a set screw
through it at or near the middle. This socket is let into the sewing
machine table C, the rim B only appearing flush with the upper surface
of the table, the socket A hanging perpendicularly below. Or the
socket may have a bracket D, Fig. 2, attached to it for clamping it

page_text: to the table instead of being let into it. A hollow pillar E is made to
slide within the socket A, and is held in its place at any height by
means of the set screw F. A metallic bracket or lamp holder G is
constructed with an arm or shank H, which is jointed to a link or scries
of links J (having free lateral but little or no vertical play). The
farthest of these links is jointed in a similar manner to the top of the
hollow pillar E; the latter can be made of one or more tubes and a
cylinder, if desired, telescoping into each other, but I prefer it in a
single piece. The metallic bracket or lamp holder aforesaid usually
consists of a ring or socket G for holding a lamp, attached to which
is another socket K or other fixture for holding a reflector L. The
latter is usually arranged so as to be adjustable at pleasure for throwing
the light in any desired direction.
Having now described my Invention, and the mode of carrying it
into effect, I wish it to be understood that I do not limit myself to the
particular design of lamp holder herein delineated and described, as the
design can be altered infinitely and yet embrace the principle of my
Invention; but what I beleive to be new and desire to claim under the
herein-before in part recited Letters Patent is,-
1st. The combination of the lamp or candle holder G with the links J
and the sliding pillar E, or their mechanical equivalents, with a sewing
machine or other similar mechanism.
2nd. The general arrangement of lamp holding apparatus, substan-
tially as described, for screwing on to or fixing into tables or other ledges
for working with.
In witness whereof, I, the said Frederick Macklin Willson, havo
hereunto set my hand and seal, this Eleventh day of May, in
