Year: 1883

page_text: LETTERS PATENT to Edwin Verity and Joshua Marland Verity of Call Lane
Leeds in the County of York Ironmongers for an Invention of "AN IMPROVED
MEANS OF STAYING OR HOLDING IN POSITION SWING OR PIVOTTED WINDOWs
PROVISIONAL SPECIFICATION left by the said Edwin Verity and Joshua
Marland Verity at the Office of the Commissioners of Patents on the
22nd March 1883.
EDWIN VERITY and JOSHUA MARLAND VERITY of Call Lane, Leeds, in the
County of York, Ironmongers, "AN IMPROVED MEANS OF STAYING OR HOLDING
IN POSITION, SWING OR PIVOTTED WINDOWS, DAMPERS, VENTILATORS, LOOKING-
GLASSES, AND SUCH LIKE THINGS,"
In constructing our improved stay as a pivot joint, we prefer generally to enlarge
the cheek face or shoulder of both the pin and the hole in which it works or what
in some cases may be the collar by which they are fixed,--and we corrugate, indent
or notch one of these faces, and fit upon the other side, against its enlarged cheek,
a similar, duplicate, cheek, with indents to fit into the former fixed, corrugated
cheek, and this (second) we construct and attach in such a manner that whilst
being fixed and definite in its movement circumferentially, it can have sufficient
movement "sideways" or "pinways to allow of the notches changing from one
to another for altering the angle of position.
We now construct-in some cases-a kind of side cam or quick screw, so placed
and employed in connection with this movable corrugated cheek (and its own fixed
one) as to be able, by a projecting arm or other equivalent, to either lock or unlock
it into or against the first named fixed cheek; and in some cases we employ, in
lieu of this cam or screw action, a side spring which shall press the before described
indented surfaces into each other, with sufficient force to act as a stay or holder,
and still allow of changes of angle or position, without requiring to be first

page_text: unlocked. We prefer generally to construct these last described parts or details
upon the pin or stud side of the first named pair of cheeks.
In some cases we construct the before described, as an independent fixing, to fit
, and act in the same manner round an ordinary pivotted joint, and in such cases,
our improved stay or holder may consist of a mere fixed indented ring.on one side,
and one or more notched or indented catches, spring or otherwise on the other
side, to take into the indents of the fixed ring..
In some cases, where it may be inconvenient to employ our stay or holder at or
round the pin or pivot which constitutes the joint, we modify our Invention by
constructing the before described indented cheeks or bosses, as an independent
joint with arms to unite it,-by other plain joints,-to the window or other
article ; and as a modification of this arrangement, we sometimes substitute a slide
and block for one of the before named arms; but in all cases retaining the notched,
indented, or corrugated cheeks or surfaces for staying or varying the position or
angle as described.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Edwin Verity and Joshua Marland Verity in the Great Seal
Patent Office on the 22nd September 1883.
EDWIN VERITY and JOSHUA MARLAND VERITY, of Call Lane, Leeds, in the
County of York, Ironmongers, "AN IMPROVED MEANS OF STAYING OR HOLDING
IN POSITION, SWING OR PIVOTTED WINDOWS, DAMPERS, VENTILATORS, LOOKING
GLASSES AND SUCH LIKE THINGS
"
In constructing our improved adjustable stay as a pivot joint, we prefer
generally to enlarge the cheek face or shoulder of both the pin and the hole in
which it works, or what in some cases may be the collar by which they are
fixed, and we corrugate, indent, or notch one of these faces, and fit upon the other
side against its enlarged cheek, a similar duplicate cheek, with indents. to fit into
the former fixed corrugated cheek, and this (second) we construct and attach in.
such a manner that whilst being fixed and definite in its movement circum-
ferentially, or in other words so that their centres shall always coincide,—it can
have sufficient movement sideways or pinways, to allow of the notches changing
from one to another, for altering the angle of position.
We now construct,-in some cases,-a kind of side cam or quick screw, so placed
and employed in connection with this movable corrugated cheek, (and its own
fixed one) as to be able, by a milled nut, projecting arm, or other equivalent, to
either lock or unlock it into or against the first-named fixed cheek. We, prefer
generally to construct these last described parts or details upon the pin or stud
side of the first named pair of cheeks.
In some cases we construct the before-described as an independent fixing or
holder at the pin or pivot, to fit and act in the same manner round an ordinary
pivotted joint, and in such cases our improved stay or holder may consist of a pair
of notched or indented rings, or a fixed, indented ring, and one or more notched or
indented catches, to take into the indents of the fixed ring.
In some cases where it may be inconvenient to employ our stay or holder at or
round the pin or pivot, which constitutes the joint, we modify our Invention by
constructing the before described indented cheeks or bosses as an independent
joint, with arms of unequal length to unite it,-by other plain joints,-to the
window or other article; and, as a modification of this arrangement, we sometimes
substitute a slide and block for one of the before-named arms; but in all cases
retaining the notched indented or corrugated cheeks or surfaces, for staying or
varying the position or angle, as described.
The accompanying illustrations are intended to show some of the various
applications and modified arrangements of our Invention, in all of which a. is the
corrugated or indented disc or cheek; (which may, in some cases, be a waved line
or holes and studs or points, in lieu of the zig zag" shown)-b. is the centre pin
or pivot, c. the screw for closing or releasing the corrugated or indented discs, and
d. the screw head or tail handle for actuating the same.
"
Having now described and particularly ascertained the nature of our said
Invention, and the manner in which the same is or may be used or carried into
effect, we wish it to be understood that we do not confine or restrict ourselves to
the precise details or arrangements which we have described or referred to, as
many modifications and variations may be made therefrom, without deviating from
the principles or main features of the said Invention; but what we consider to be
novel and original and therefore claim as the Invention secured to us by the
herein-before in part recited Letters Patent is :-
The construction, application and use of notched, indented, or corrugated cheeks,

page_text: discs, or faces, acting circumferentially round or in connection with the centre pin
or pivot of swing or pivotted articles, and the "independent joint" modification
thereof, for the purpose, and virtually as or after the manner herein-before
described and set forth.
In witness whereof, we, the said Edwin Verity and Joshua Marland Verity
have hereunto set our hands and seals this Thirty-first day of August, in the
year of our Lord, One thousand eight hundred and eighty three.
Witness.-
