COMPLETE SPECIFICATION.
Cushioned Holdfast.
WILLIAM COOPER FLETCHER, 36, Havelock Street, Sheffield, Advertising
Agent, and DAVID CRAVEN, Darnall, near Sheffield, Railway Carriage Builder,
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:-
.
Our invention consists in constructing a holdfast having a cushion of india
rubber, gutta percha, leather, or other durable elastic material securely placed, so
as to rest between the head of the holdfast & the surface of the tablet or other
article requiring to be affixed on, or against any wall, hoarding, or structure, and by
this provision avoiding the damaging of the article. In order that the carrying out
of our invention may be clearly & fully understood we have illustrated the same
on the accompanying sheet of drawings and have marked them with letters of
reference corresponding with the following description thereof :-
Figure 1 is an elevation or side view of the holdfast & cushion, A is the holdfast
pointed or screwed at the bottom end as shown, & this part we make of various
lengths suitable for the material or substance into which it is intended to be inserted,
driven, or screwed. B is the cushion formed to suit the dovetail shaped space
under the head of the holdfast A.
Figure 2 is a view of the back of the holdfast & showing the cushion B
slightly projecting beyond the sides thereof.
Figure 3 shows the head or top of the holdfast, the dotted lines indicating the
cushion.
The illustration is full size, but we make them in sizes to suit the weight of the
article.
When this holdfast is driven into the structure to or against which the tablet
or article is to be fixed, the cushion is compressed against the said tablet or article
and thus secured in its place under the heads of the holdfast, and by this provision
the necessity of driving the holdfast itself against the surface of the tablet or
article is avoided & also the danger of damaging the same.
.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The construction of a holdfast in combination with a cushion as described
and illustrated, for the purpose of affixing tablets or articles of brittle substance
substantially as set forth and described.
