PROVISIONAL SPECIFICATION left by the said William Robinson at
the Office of the Commissioners of Patents, with his Petition, on the
1st January 1863.
I, WILLIAM ROBINSON, of Birmingham, in the County of Warwick, Manu-
facturer, do hereby declare the nature of the said Invention for "AN IM-.
PROVEMENT OR IMPROVEMENTS IN GLASSES FOR LAMPS USED IN SHIPS, RAILWAY
CARRIAGES, AND FOR OTHER LIKE PURPOSES," to be as follows, that is to say:-
My Invention consists in moulding or otherwise forming these glasses,
which are usually of a globular or hemispherical form, with raised ribs or
flanges on the outside surface; these ribs or flanges may be in any suitable
form or design, and by their projection from the surface they preserve such
surface from being scratched in placing the glasses in their positions, whilst at
the same time a brilliant light and ornamental appearance are also ensured.

by the said William Robinson in the Great Seal Patent Office on the
1st July 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBINSON, of Birmingham, in the County of Warwick, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of January, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Robinson, Her special license, that I, the said William
Robinson, my executors, administrators, and assigns, or such others as I,
the said William Robinson, 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, tho Channel Islands, and Isle of Man, an Invention
for "AN IMPROVEMENT OR IMPROVEMENTS IN GLASSES FOR LAMPS USED IN SHIPS,
RAILWAY CARRIAGES, AND FOR OTHER LIKE PURPOSES," upon the condition
(amongst others) that I, the said William Robinson, by an instrument in
writing under my hand and seal, 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 Robinson, 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, reference being had to the Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say) :-
My Invention consists in moulding or otherwise forming these glasses,
which are usually of a globular or hemispherical form, with raised ribs or
flanges on the outside surface; these ribs or flanges may be in any suitable
form or design, and by their projection from the surface they preserve such
surface from being scratched in placing the glasses in their positions, whilst
at the same time a brilliant light and ornamental appearance are also
ensured.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 represents a front elevation of one of my improved glasses;
Figure 2, shewing one half of the plan externally, and one half of a section on
the line A, B:
The radial lines R. shew the ribs or projections moulded or pressed upon the
outer surface of the glass. These ribs, although here represented as radial,
may, if preferred, assume any other direction with equal utility, as far as
regards the purpose for which they are intended, which is that of preserving
the surface of the glass from contact with the sides or edges of the opening
through which it is suspended in the roof of a carriage or ship cabin, or in
other like positions, or in the tressels or frames in which they are carried or
placed when not in use by those who have the charge of them. With the
glasses at present in use for the purposes above named, the surface is so
scratched by frequent removals, that the light is to a great extent obscured,
and a very unsightly appearance is produced. These evils are remedied by
making the glasses according to this Invention, and an ornamental appearance
with considerable additional strength and increased brilliancy of light are
obtained.
Having thus described. the nature of the said Invention, and in what
manner the same is to be performed, I do not confine myself to any precise
form for the ribs or projections, or to the manner in which the glasses may be
made; but I claim the improvement or improvements in glasses for lamps
used in ships, railway carriages, and for other like purposes, as herein more
fully set forth and specified.
In witness whereof, I, the said William Robinson, have hereunto set my
hand and seal, this Twenty-sixth day of June, in the year of our Lord
One thousand eight hundred and sixty-three.
WILLIAM RODINSON. (L.B.)
