Year: 1874

page_text: LETTERS PATENT to John Allin Jones, of Birmingham, in the County
of Warwick, Agent, for the Invention of "CERTAIN IMPROVEMENTS IN
WATCH TATION OF SLIDING SASHES.
"
Scaled the 14th August 1874, and dated the 20th February 1874.
PROVISIONAL SPECIFICATION left by the said John Allin Jones at
the Office of the Commissioners of Patents, with his Petition, on
the 20th February 1874.
I, JOHN ALLIN JONES, of Birmingham, in the County of Warwick,
Agent, do hereby declare the nature of my said Invention for " CERTAIN
Improvements IN THE CONSTRUCTION OF SLIDING SAshes," to be as follows (that
is to say) :-
My improvements consist in applying to the stiles of sashes, outer or
auxiliary stiles fitted with a lateral tongue to work in a groove or other-
wise in the parting beads of the sash frame, the said stiles being a little
thicker than the ordinary side beads of the sash frame, and to those
auxiliary stiles the sash cords are secured, and to one or other of those

page_text: said stiles the sashes are attached by ordinary butt hinges so as to permit
the top and bottom sash to open inward, by preference right and left
(that is to say), the top may open to the left, and the bottom to the
right, or the reverse; and to the opposite auxiliary stiles I apply pro-
jections, or recesses, or bolts, or other equivalent means for holding and
securing the top and bottom sashes in connection with their respective
auxiliary stiles so as to unite them in one for the purpose of sliding up
and down for opening in the ordinary way, in which position they will
resemble the sashes now generally in use.
In order to permit the sashes passing each other while being opened
I cause the sash frame to be made slightly higher than is required for
the two sashes, by which means they are allowed to pass each other in
the process of opening, which is effected in the following way :-The
upper sash is pulled down and the lower one pushed up, when they are
respectively free from the detents or means of uniting them to their
respective auxiliary stiles, thereby permitting the sashes to open inwards
towards the room, just like opening a door, for cleaning, painting, or
restoring, and to be afterwards replaced in position in like manner.
This arrangement will permit of the use of the ordinary sash fastener as
commonly applied.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Allin Jones in the Great Seal Patent Office
on the 19th August 1874.
то ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
ALLIN JONES, of Birmingham, in the County of Warwick, Agont, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of February, in the
year of our Lord One thousand eight hundred and seventy-four, in tho
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Allin Jones, Her
special license that I, the said John Allin Jones, my executors,
administrators, and assigns, or such others as I, the said John Allin
Jones, my executors, administrators, or assigns, should at any time
agree with, and no others, from time to time and at all times thereafter

page_text: during the term therein expressed, should and lawfully might make,
use, excrcise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"CERTAIN IMPROVEMENTS IN THE CONSTRUCTION OF SLIDING WINDOW SASHES,"
upon the condition (amongst others) that I, the said John Allin Jones,
my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, 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 in tho
Great Scal Patent Offico within six calendar months next and immedi-
ately after the date of the said Letters Patent.
NOW KNOW YE, that I, tho said John Allin Jones, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Drawings, and to the letters and figures marked thereon, that is to
say :-
My improvements consist in applying to the stiles of sashes outer or
auxillary stiles fitted with a lateral tongue to work in a groove or other-
wise in the parting beads of the sash frame, the said stiles being a little
thicker than the ordinary side beads of the sash frame, and to these
auxillary stiles the sash cords are secured, and to one or other of the
stiles the sashes are attached by ordinary butt hinges so as to permit the.
top and bottom sash to open inward (by preference) right and left (that
is to say), the top may open to the left, and the bottom to the right, or
the reverse; and to the opposite auxillary stiles I apply projections, or
recesses, or bolts, or other equivelent means for holding and securing
the top and bottom sashes in connection with their respective auxillary
stiles so as to unite them in one for the purpose of sliding up and down
for opening in the ordinary way, in which position they will resemble
the sashes now generally in use.
In order to permit the sashes passing each other while being opened
I cause the sash frame to be made slightly higher than is required for
the two sashes, by which means they are allowed to pass cach other in
the process of opening, which is effected in the following way :—The
upper sash is pulled down and the lower one pushed up when they are
respectively free from the detents or means of uniting them to their
respective auxillary stiles, thereby permitting the sashes to open inward
1

page_text: towards the room just like opening a door, for cleaning, painting, and
restoring, and to be afterwards replaced in position in like manner. This
arrangement will permit of the use of the ordinary sash fastener as
commonly applied.
But as the description will be much aided by reference to the Drawings
hercunto attached, and to the figures and letters marked thereon, I will
describe in detail my Invention in connection with the said Drawings
(that is to say) :-
A
Fig. 1 represents the inside view of a sash frame and sashes, but which
may vary in shape, size, and detail as may be desired or preferred. The
general construction of the sash frame differs but very little from those
commonly in use, consisting simply of the auxillary stiles in connection
with the sides of the sashes and the introduction of the head rail A, A.
This rail is by preference grooved or tongued to correspond with the top
rail of the top sash which affords protection from the wind without as
well as to prevent draughts. The sash pullies and sash weights required
for a counterpoise are just the same as those now commonly in usë,
but instead of the cords being united to the sides of the sliding sashes
they are united to the auxillary stiles, as will be hereafter seen.
Fig. 2 is a section of Fig. 1 taken through a dotted line B, C. The
lower sash in this view is represented open, marked D, but when closed
the rabbit E abuts against the corresponding rabbit of its outer sliding
stile F, whilst the sliding hanging stile G has a circular projecting bead
which fits the corresponding vertical stile of its annexed sash D, which
will have the effect of making the hanging stile of the sash D with its
sliding auxillary stile G more weatherproof. The sash D while in this
position may be thoroughly cleaned, closed, and elevated, when the top
sash proper may be pulled down, and being hung to its corresponding
auxillary right-hand sliding stile, it will be found from the bottom sash
being elevated so that its top part passes up in front of the rail A, A,
there will be room enough underneath its lower rail for the top sash
when pulled down to permit its being opened inwards, as shown by the
dotted lines H, which simply represent the top rail of the top sash
pulled down and opened in position for cleaning the respective side and
auxillary stile appertaining to this sash, being rabitted and beaded as
in the stiles of the lower sash before described, I, I, and J, J, being
simply the vertical recesses for the sash weights to work in,

page_text: Figs. 3 and 4 are corresponding vertical sections of Fig. 2, with the
exception of the removal of the major part of the sill piece P, P, to
ecomize space, as also the sashes, which are supposed to be removed
from their respective hinges K and L. These sections are merely
introduced for the better definement of the mode which may be adopted
in fitting and arranging the auxillary stiles G, F, and M, N, but which
parts may be otherwise fitted if so desired; as for instance, in the way.
in which they are arranged as exhibited in the corresponding soction at
Fig. 5, wherein the rabbiting of the sash bead R and S is supercceded
by the inner overlapping bevel there shown; and the parting bead T is
also slightly modified from the corresponding part in the former Figures.
In Fig. 1 I have represented the under sash as being bolted to its
corresponding auxillary stile, but any other form or construction, or
portable means of locking this auxillary stile to the sash may be adopted,
as the union is essential, that the entire sash and auxillary stiles may
work as one when being elevated or used for the ordinary purposes of
elevating or pulling down the sash, as well as the prevention of the
pressure of external currents pressing against the sash, and to counteract
the unequal weight as a counterpoise to the sash weight when the bolts
are drawn back from the auxillary stile a detent or frictional brake may
be applied, working through the sash bead and bearing on the front
bevel or rabitted edge of the auxillary stile U, and which brake I have
exhibited detached at Fig. 6, so designed that by pressure with the finger
on the button V sufficient pressure will be afforded to prevent the part
being suddenly drawn up by the force of the sash weight..
In some cases it may be preferred to lift the sashes off the hinge for
complete removal for cleaning or otherwise, which may be readily
effected by using hinges of the description exhibited at Fig. 7.
Having thus given a description of my Invention, and the manner in
which the same may be carried into effect, nevertheless I do not purpose
confining myself to the size or details herein described and set forth,
as the whole may be varied without departing from the spirit of my
Invention. But what I claim and wish to protect by these my in
part recited Letters Patent is, the facilities herein described and set forth
whereby sashes may be so constructed and connected. by means of
auxillary stiles to their respective frames and counterpoising weights as.

in use and yet permit of being opened laterally inward for cleaning.
In witness whereof; I, the said John Allin Jones, have hereunto
set my hand and seal, this Eighteenth day of August in the year
of our Lord One thousand eight hundred and seventy-four.
