IMPROVEMENTS IN THE MANUFACTURE OF FLUSH SASH LIFTS, & DRAWER PULLS, WHICH ARTICLES ARE ALSO APPLICABLE TO OTHER SIMILAR PURPOSES
Year: 1886

page_text: I, JAMES FRANK HOWARD CARTLAND, of Constitution Hill, Birmingham, in the
county of Warwick, Brassfounder, do hereby declare the nature of my invention
for IMPROVEMENTS IN THE MANUFACTURE OF FLUSH SASH LIFTS, & DRAWER PULLS,
WHICH ARTICLES ARE ALSO APPLICABLE TO OTHER SIMILAR PURPOSES, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention, relates to improvements in the manufacture of articles known
and used as flush sash lifts, drawer pulls, and for other similar purposes, and has
for its object their manufacture, by stamping, pressing, and other finishing processes
from one piece of wrought metal.
Hitherto these articles have been either made of cast metal, or they have been
constructed by stamping, &c out of sheet metal but formed of two pieces; in this
invention however I form the complete lift or pull, out of one piece of metal, such
lift or pull also having formed upon its interior, a raised rib or ridge, against
which the pull or lift takes place, or, is very much assisted.
In order to explain this my invention more clearly, I have appended hereunto an
illustrative sheet of drawings upon which are figures and letters of reference, like
letters referring throughout to the same thing or part,
Fig. 1 shews a plan of a piece of sheet metal from which a lift or pull may be
made according to this my invention.
Fig. 2 is a cross section of Fig. 1 at A-B. A piece of metal similar to Fig. 1
would be placed in a stamp or press provided with suitable tools, by which it would
be drawn, pressed, or stamped into a sectional shape similar to that shewn in Fig. 3,
its depressed part a, being of a length about the same as shewn from 6 to c, in
Fig. 6.
This drawing, pressing, or stamping, of this depressed part, may consist of one or
more operations according to the depth required. In the drawing it is shewn as
being accomplished from Fig. 1 and 2, to Fig. 4, in two operations. If necessary
annealing processes would be resorted to between the different operations. -

page_text: After being brought into a shape similar to that shewn in section Fig. 4, it is
then gripped or pressed by suitable tools, in an ordinary press or other machine,
and the raised rib or ridge d, formed, for the purposes already mentioned.
If desired this my "lift” or “pull" may be ornamented in various ways, and
particularly by forming the stamping or press tools with any fluted, scroll, or other
ornamental figured designs, so as to reproduce such designs upon the interior part
of the lift or pull, as shewn for instance in Figs. 7 and 8; similar ornamentation
may be also carried out upon the surface e, if desired, or such surfaces may be
recessed for ornamentation, and then filled in with black, vermillion, or other
colored substances. Necessary holes f for attachment would be provided according
to requirement, taste, or design. By describing these articles as being made of
metal, I mean, of any metal having sufficiently ductility in its nature for the
operations necessary.
Having now particularly described and ascertained the nature of my said.
invention, and in what manner the same is to be performed, I declare that what
I claim is -
.
1st. The improvements in the manufacture of flush sash lifts, drawer pulls, and
such similarly shaped articles, as herein set forth, that is to say, the making of such
articles complete out of one piece of wrought metal.
2nd. The forming of the raised rib or ridge d, from the metal of the depressed
part of the "lift" or "pull."
