IMPROVEMENTS IN JOINTS FOR THE STICKS OF PARASOLS AND OTHER LIKE PURPOSES
Year: 1853

page_text: LETTERS PATENT to Adam Cyrus Engert, of Mora Place, City
Road, in the County of Middlesex, manufacturer, for the Invention
of "IMPROVEMENTS IN JOINTS FOR THE STICKS OF PARASOLS AND OTHER
LIKE PURPOSES."-A communication from Alexander Porecky.
Sealed the 16th August 1853, and dated the 23d February 1853.
PROVISIONAL SPECIFICATION left by the said Adam Cyrus Engert
at the Office of the Commissioners of Patents, with his Petition,
on the 23d February 1858.
I, ADAM CYRUS ENGERT, of Mora Place, City Road, in the County
of Middlesex, manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN JOINTS FOR THE STICKS OF PARASOLS AND
OTHER LIKE PURPOSES," which has been communicated to me by Alexander
Porecky, a foreigner, residing abroad, to be as follows:-
My Improvements consist in manufacturing a spring joint. I take
a piece of steel or other metal, and bend it up in the form of a tube; or
I take metal tube, and make a slit along its whole length. I widen this

page_text: slit by introducing what I term cheek or side pieces. This spring tube
forms the centre part of my joint. At each end I introduce through
the slit the flattened end of a socket, ferrule, or tube, and retain it
between the cheek pieces by a pin or stud, which, however, does not
traverse the central part of the joint. The cheek or side pieces are
retained within the spring slit tube by a stud or pin. One socket
carries the handle of the parasol stick, and the other the top of the
stick.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Adam Cyrus Engert in the Great Seal Patent
Office, on the 23d' August 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
ADAM CYRUS ENGERT, of Mora Place, City Road, in the County of
Middlesex, manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of February, in the
year of our Lord One thousand eight hundred and fifty-three, in the
sixteenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Adam Cyrus Engert, Her special
licence that I, the said Adam Cyrus Engert, my executors, administra-
tors, and assigns, or such others as I, the said Adam Cyrus Engert,
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, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN JOINTS FOR THE STICKS OF PARASOLS AND OTHER LIKE
PURPOSES," communicated to me by Alexander Porecky, upon the con-
dition (amongst others) that I, the said Adam Cyrus Engert, 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

page_text: 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 Adam Cyrus Engert, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, reference being had to the drawings
annexed; that is to say:
The said Improvements consist in manufacturing a spring joint, as
herein-after described.
Figure 1, is a side elevation of a joint for the stick of a parasol
constructed according to the Invention; Figure 2, is a vertical section
of the same; and Figures 3, and 4, different views of some of the parts
detached. a, is a tubular spring composed of a piece of spring steel or
other metal bent up into the form of a tube, but with the edges not
quite touching each other, or produced by taking a tube of similar
metal and making a slit along one side of it, and throughout its whole
length. b, is a filling or intermediate piece, (shown separately in
Figure 8,) at each end of which is formed a slot or recess c, so as to
leave cheek or side pieces, as shewn, and which is introduced within the
tubular spring a, and secured there by a pin d, at the middle of its
length. c, e, are sockets, tubes, or ferrules for receiving the two parts
of the parasol stick, and having at one end a flattened piece of metal f,
(as shewn in Figure 4,) by means of which they are jointed to the ends
of the filling piece b, by pins g, g, which pass through the ends of the
filling piece from side to side, and through the flattened parts f, f, of
the sockets or tubes e, e, but do not extend to or touch against the
interior of the tubular spring a. The flattened parts f,f, of the sockets
e, e, have grooves at each side, into which the edges of the tubular spring
a, fall, so as to keep the joint stiff when the parasol stick or other
article to which it is applied is not required to be folded; and the outer
edges of the parts f, f, are made to taper slightly from the inner end, to
enable the joint to be more easily folded. The folding is effected by
turning the sockets by means of the parts of the stick inserted in them
so as to bring these parts parallel to each other, or at any intermediate
angle, in which position they will be retained by the spring a. Joints

page_text: of this construction may also be applied to other purposes than the
folding of parasol sticks, as, for instance, the securing the blades of knives
to the handles, &c. &c.; and the modifications necessary to be made
to adapt them for such purposes will readily suggest themselves to a
competent workman.
And having now described the nature of the said Invention, and in
what manner the same is to be performed, I declare that what I claim
is,—
The employment in the construction of joints for the sticks of parasols
and other like purposes of a tubular spring arranged in the manner and
for the purposes herein-before described.
In witness whereof, I, the said Adam Cyrus Engert, have hereunto
set my hand and seal, this Twenty-second day of August, Onc
thousand eight hundred and fifty-three.
