TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
RAMSEY, of 83 & 84, Farringdon Street, in the City of London, Glass
Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of December, in the
year of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto the said William Ramsey, Her special
licence that I, the said William Ramsey, my executors, administrators,
and assigns, or such others as I, the said William Ramsey, my executors,
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 "AN IMPROVEMENT
IN GLASS-CUTTING INSTRUMENTS," upon the condition (amongst others)
that I, the said William Ramscy, my exccutors or administrators, by
an instrument in writing under my, or their, or one of their hands and
seals, 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 Letters
Patent.
NOW KNOW YE, that I, the said William Ramsey, do hereby declare
the nature of my said 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 consists in fixing in the block of the glass-cutting
instruments a wheel or roller made of any suitable metal or material, and

page_text: so placed that in cutting the wheel or roller revolves, and having thereby
an equal bearing on the diamond or other cutter placed in said block a
direct cut is effected, causing a great saving in time and wear and tear
of cutter, and adapts the instrument so as to be used by the merest
novice.
In order to make the Invention more easily understood I will now
refer to the annexed Drawing (having the same letters of reference to
the corresponding parts), in which Fig. 1 shows a side view of a glass-
cutting instrument a; b is the steel cutting wheel; c is the wheel or
roller fixed on a pin; Fig. 2 is a plan view; and Fig. 3, side view
enlarged.
The wheel or roller c can be fitted in same manner to the block of the
stem of a diamond or any other similar cutter.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be carried
into practical effect, I would observe in conclusion that I do not refrain
or restrict myself to the precise details or size of wheel or roller, as
many variations, may be made therefrom without deviating from the
main features of my Invention; but what I claim is, the placing and
adjusting of a wheel or roller to the block of glass-cutting instruments,
substantially as herein-before described and illustrated in the Drawing.
In witness whereof, I, the said William Ramsey, have 'hereunto
set my hand and seal, this day of June, in the year of our
Lord One thousand eight hundred and seventy-four.
