TIVO VIDIONAL DITUIFICATION.
An Improvement in the Manufacture or Construction of Attachable
Letters, Figures, Designs, and the like.
We, SIR W. G. ARMSTRONG, WHITWORTH & Co, LIMITED, and THOMAS WYSE,
Shipbuilder, both of Walker Shipyard, Newcastle upon Tyne, do hereby declare
the nature of our said invention to be as follows:-
-
Our invention relates to that description of letters, signs, and the like which
are usually cast in metal and subsequently faced, such letters and the like
being formed with a number of spikes integral therewith or with holes for screws
for attachment.
According to our invention we cut or stamp, the letters and the like from
sheet metal in such a manner that the ends or (and) sides of such letters and
the like are extended in the form of barbed prongs or tangs. These barbed
prongs or tangs are bent at right angles to the letter or the like and are adapted
to be driven into the material to be lettered or decorated.
The barbed tangs or prongs may be, in some cases, stamped out of the sub-
stance of the letter or the like thereby imparting an ornamental appearance as
well as providing an efficient means of attachment.
Letters, figures and other characters, signs and the like made for attachment
in this manner are readily adaptable to curved as well as flat surfaces.

SIR W. G. ARMSTRONG, WHITWORTH & Co. LTD.,
An Improvement in the Manufacture or Construction of Attachable
Letters, Figures, Designs, and the like.
SiR W. G. ARMSTRONG, WHITWORTH & Co. LIMITED, and THOMAS WYSE,
Shipbuilder, both of Walker Shipyard, Newcastle upon Tyne, do hereby declare
the nature of our said invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following state-
ment:-
Our invention relates to that description of letters, signs, and the like which
are usually cast in metal and subsequently faced, such letters and the like

page_text: being formed with a number of spikes integral therewith, or with holes for screws
for attachment.
According to our invention we cut or stamp the letters and the like from
sheet metal in such a manner that the ends or (and) sides of such letters and
the like are extended in the form of barbed prongs or tangs. These barbed
prongs or tangs are bent at right angles to the letter or the like and are adapted
to be driven into the material to be lettered or decorated.
The barbed tangs or prongs may be, in some cases, stamped out of the sub-
stance of the letter or the like thereby imparting an ornamental appearance as
well as providing an efficient means of attachment.
Letters, figures, and other characters, signs and the like made for attachment
in this manner are readily adaptable to curved as well as flat surfaces.
And in order that our said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, illustrating our
method of forming letters with barbed prongs or tangs, from which the applica-
tion of our invention to figures, designs, and the like, will be readily understood
and in which drawings similar letters of reference indicate corresponding parts.
Fig. 1 is an elevation showing the barbed prongs or tangs formed at the ends
of the latter.
Fig. 2 shows the method of forming the prongs or tangs integral with the
body of the letter.
Fig. 3 is a side view of Fig. 2.
Referring to Fig. 1 the barbed prongs or tangs a are so formed that, when
turned backwards, and driven into any material or floated into cement or the
like, the letter only is exposed to view, and is firmly secured in position.
In Fig. 2 the prongs or tangs a are shown in position previously to being
bent backwards, as shown in Fig. 3, for attachment.
It is obvious that the prongs or tangs shown in Figs. 2 and 3 may be modified
in form so as to form part of an artistic design embodied in the construction
of the letter; also that the methods of construction and attachment herein
described are applicable to a great variety of figures, designs, and analogous
articles.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is:-
An improved manufacture or construction of attachable letters, figures, designs
and analogous devices, consisting of stamping or cutting the same out of sheet
metal with barbed prongs or tangs integral therewith in the manner substantially
as and for the purposes described and illustrated by the drawings.
