Improvements in Letters for Attachment to Surfaces.
JOSEPH HENRY ROBINSON of 74 North Hill Street Liverpool in the County of
Lancaster, Enameller do hereby declare the nature of this invention to be as follows:-
In place of the usual sharp corners as at present adopted in forming the copper
blanks for the manufacture of enamel letters, in forming the tin plate blanks for
japanned letters, and in cutting out glass letters of the various kinds I cause to be
cut away all freo corners of the blanks in the case of enamel on copper and japanned
on tin plate letters-and of the letters in the case of cutting out glass letters-to a
rounded curve or in some cases to what may be termed a blunted curve, thus leaving
no sharp corners, all being as clear as in the case of the ordinary letter O. Hitherto
great trouble has been caused by the sharp corners on enamelled, on japanned and on
opal and other glass letters getting entangled with wash leathers and dusters in the
course of cleaning frequently damaging, and sometimes actually breaking, the said
letters, this ny invention as hereinbefore described is for the purpose of entirely
preventing such mishaps.

Improvements in Letters for Attachment to Surfaces.
JOSEPH HENRY ROBINSON 74, North Hill Street Liverpool in the County of
Lancaster Enameller do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
In place of the usual sharp corners as at present adopted in forming the copper
blanks for the manufacture of enamel letters, in forming the tin plate blanks for
japanned letters, and in cutting out glass letters of the various kinds, I cause to be
cut away all free corners of the blanks in the case of enamel on copper and of
japanned on tin plate letters-and of the letters in the case of cutting out glass letters-
to a rounded curve or in some cases to what may be termed a blunted curve, thus
leaving no sharp corners, all being as clear as in the case of the ordinary letter O.
Hitherto great trouble has been caused by the sharp corners on enamelled, on
japanned, and on opal and other glass letters getting entangled with wash leathers
and dusters in the course of cleaning, frequently damaging and sometimes actually
breaking the said letters, this my invention as herein before described is for the
purpose of entirely preventing such mishaps. It will thus be seen that my invention
relates to letters and the like for attachment to surfaces, as numbers, ampersands,
ornamental finals, bars, and other attachments manufactured whole or in sectional
parts and is designed to cause the same to be constructed in a manner to prevent
accidental damage thereto in the act of cleaning the said letters and the like and the
surfaces to which they may he attached also permitting of easier removal and
refixing. In order that my method of forming the improved enamelled on copper
letters, japanned on tin plate letters, and the various kinds of glass letters and the
like may be clearly understood I attach a sheet of drawings with references and
explanations as follows viz.:-
Figures 1, 2, 3 shew the ordinary block type of letters and an ampersand all having
the rounded corners which may of any curve required.

page_text: Figures 4, 5, 6, 7, 8, 9 shew letters and figures having the corners rounded in any
curve, in sectional parts.
Figure 10 shows a letter having double curved corners or ends.
I do not confine myself in any way to the forms of letters and the like, figured in
the drawings, they are merely for the purpose of more clearly describing my
invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what 1
claim is
1 Letters and the liko-substantially as described herein before-adapted to bo
secured to surfaces by any of the well known methods so that the said letters and
the like do not present any sharp points or angles around their edges or
outlines.
2-Letters and the like constructed substantially as hereinbefore described for the
purposes set forth.
3-The improvements in letters and the like herein before described and illustrated
substantially as and for the purposes set forth.
Dated this 24th day of September 1890.
