page_text: LETTERS PATENT to Jane Cassandra Wilks Featherstonhaugh of Park Street
Grosvenor Square in the County of Middlesex Administratrix of the late
Greville Henry Frederick Featherstonhaugh of Park Street, Grosvenor Square,
in the County of Middlesex, deceased, for an Invention of IMPROVEMENTS IN
PRINTERS' QUOINS OR LOCKING-UP ADDARATHIS
PROVISIONAL SPECIFICATION left by the said Greville Henry Frederick
Featherstonhaugh at the Office of the Commissioners of Patents on the
31st December 1883.
GREVILLE HENRY FREDERICK FEATHERSTONHAUGH of Park Street, Grosvenor
Square in the County of Middlesex, "IMPROVEMENTS IN PRINTERS' QUOINS OR
LOCKING-UP APPARATUS"
My invention has for object to enable pages of type to be readily locked up
in a chase in such a way as to obviate what is technically known as "hanging,"
which is liable to occur when the locking-up devices employed have a drawing
action as is usual. My apparatus is applicable also for locking up chases on the
beds of printing machines.
A printers quoin or locking up apparatus according to my invention comprises a
right and a left handed male screw with intermediate enlargement, and two cheeks
or plates with parallel sides, one of these cheeks or plates being formed with a
female thread to receive the right handed male screw: the other with a female
thread to receive the left handed male screw (or as a modification a swivel may be
substituted for one of the male and female screws) With this arrangement, as
will be readily understood, if the screws be turned in one direction they will cause
the two cheeks or plates to mutually approach,-by turning the screws the contrary
way, the cheeks or plates will be caused to recede from one another, thus expanding
the quoin or locking-up apparatus. The enlargement between the right and left-
handed male screws may be made of square or polygonal form in cross section, to
receive a spanner or other suitable device for turning the screws. It will be
understood that the two male screws with intermediate enlargement are made all
in one piece, also that the entire apparatus must be constructed of metal suitably
hard to withstand the wear and tear to which devices of this class are subject in
practical use. Wrought iron is a suitable material.

by the said Jane Cassandra Wilks Featherstonhaugh, Administratrix of
the late Greville Henry Frederick Featherstonhaugh, deceased, in the Patent
Office on the 28th June 1884.
JANE CASSANDRA WILKS FEATHERSTONHAUGH of Park Street Grosvenor Square
in the County of Middlesex, administratrix of the late Greville Henry Frederick
Featherstonhaugh of Park Street, Grosvenor Square in the County of Middlesex,
deceased IMPROVEMENTS IN PRINTERS QUOINS OR LOCKING UP APPARATUS.
"
This invention has for object to enable pages of type to be readily locked up
in a chase in such a way as to obviate what is technically known as "hanging,"
which is liable to occur when the locking up devices employed have a drawing
action as is usual.
The improved apparatus is applicable also for locking up chases on the beds of
printing machines.
A printers quoin or locking up apparatus according to this invention comprises
a right and a left handed male screw with intermediate enlargement, and two cheeks
or plates with parallel sides, one of these cheeks or plates being formed with a
female thread to receive the right handed male screw: the other with a female
thread to receive the left handed male screw (or as a modification, a swivel may
be substituted for one of the male and female screws). With this arrangement, as
will be readily understood, if the screws be turned in one direction they will cause
the two cheeks or plates to mutually approach; by turning the screws the contrary
way, the cheeks or plates will be caused to recede from one another, thus expanding
the quoin or locking-up apparatus. The enlargement between the right and left-
handed male screws may be made of square or polygonal form in cross section, to
receive a spanner or other suitable device for turning the screws. It will be
understood that the two male screws with intermediate enlargement are made all
in one piece, also that the entire apparatus must be constructed of metal suitably
hard to withstand the wear and tear to which devices of this class are subject in
practical use. Wrought iron is a suitable material.
Referring to the accompanying drawings
:
Fig 1 is a plan or top view of apparatus embodying the said invention and Fig. 2
is a side view of the same.
a, al are two cheeks or plates each made with parallel sides and with female
screw-threaded holes b. 6¹ the screw thread of one being right-handed whilst that
of the other is left handed. c is a rod or bolt provided at one of its ends with a
right handed male screw thread and at its other end with a left handed male screw
thread.
The intermediate portion of the rod or bolt between the right and left
handed screwed portions is made of square or polygonal form in cross section to
receive a spanner or other suitable device for turning it. Or the said portion c¹
may be provided with holes to receive a rod or rods for the same purpose.
It will be evident that if such a quoin or locking up apparatus be applied to a
chase containing type and the screwed rod or bolt c be turned in the direction to
cause the two cheeks or plates a. a¹ to recede from one another, the type will be
securely locked in position; while by turning the said screwed rod or bolt c in the
opposite direction the two cheeks will be caused to approach each other and thus
release the type. Instead of the rod or bolt c screwing into both cheeks or
plates a. a' as above described, it may be connected at one end to one of the cheeks
or plates by a swivel in such a manner that it may rotate without imparting motion
to such cheek or plate whilst its other end being made with a screw will operate
the other cheek or plate in the manner hereiuabove described.

page_text: It will be evident that instead of using two short cheeks or plates connected by
only one screwed rod or bolt two longer cheeks or plates connected by two or more
screwed rods or bolts may be used.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be carried into practical effect, what
I claim is :-
1. A printers quoin or locking up apparatus comprising a right handed and a
left handed male screw with intermediate enlargement, and two cheeks or plates
with parallel sides, one of these cheeks or plates being formed with a female thread
to receive the right handed male screw, and the other with a thread to receive the
left handed male screw, as hereinabove described with reference to and illustrated
in the drawing.
2. The modified construction of printers quoin or locking up apparatus herein-
above described comprising two cheeks or plates with parallel sides and a rod or
bolt formed at one end with a male screw thread to take into a correspondingly
screwed hole in one of the cheeks or plates and connected at the other end by a
swivel connection to the other cheek or plate.
In Witness whereof I the said Jane Cassandra Wilks Featherstonhaugh have
hereunto set my hand and seal this twenty-eighth day of June in the Year of Our
Lord, one thousand eight hundred and eighty-four.
