page_text: LETTERS PATENT to Hugo Worthington, of Liverpool, in the County of
Lancaster, for the Invention of "AN IMPROVED METHOD OF AND APPARATUS
FOR RAISING, LOWERING, AND FASTENING WINDOWS, PARTICULARLY APPLICABLE
TO RAILWAY AND OTHER CARRIAGE WINDOWS."
Sealed the 19th June 1877, and dated the 15th January 1877.
PROVISIONAL SPECIFICATION left by the said Hugo Worthington at the Office
of the Commissioners of Patents on the 15th January 1877.
HUGO WORTHINGTON, of Liverpool, in the County of Lancaster. "AN IMPROVED
METHOD OF AND APPARATUS FOR RAISING, LOWERING, AND FASTENING WINDOWS,
PARTICULARLY APPLICABLE TO RAILWAY AND OTHER CARRIAGE WINDOWS."
My Invention relates to a novel method of raising, lowering, and fastening
windows, and is particularly applicable to windows, such as railway and other
carriage windows.
In applying my Invention to, say, a railway carriage window, I am enabled to
dispense with the ordinary lifting straps, also with the retaining or steadying side
springs now commonly used.
My Invention consists of a double bolt which is mounted in the top or on the top of
the sliding window frame or sash. The double bolt is carried on a duplex lever, and is
so arranged that the lever being worked, the bolts are drawn in or driven out on
each side of the sliding frame or sash respectively. The ends or tips of the bolts are
mounted with india-rubber buffers, which, when the bolts are thrown out, bear
against the main frame, and prevent the sliding frame from moving, and also steady
the sliding frame. The lever is operated by a suitable handle fixed on the sliding
frame or sash, which handle also serves for raising or lowering the window, and by
turning the handle the window is fixed in any required position.
A modification may consist of dispensing with the india-rubber tips on the bolts
and substituting strips of india-rubber on the window frame, against which the
bolts bear. To insure the bolts holding, the sides of the window frame may be
perforated, roughed, corrugated, or otherwise indented to receive the bolts.
A second modification consists in working the bolts by means of having a right
and left landed screw formed respectively on the inner ends of the bolts, such right
and left-hand screws working into a barrel having right and left-handed female screws
to receive same, and such barrel being operated upon by a lever or handle,

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Hugo Worthington in the Great Seal Patent Office on the 7th July
1877.
HUGO WORTHINGTON, of Liverpool, in the County of Lancaster. "AN IMPROVED
METHOD OF AND APPARATUS FOR RAISING, LOWERING, AND FASTENING WINDOWS,
PARTICULARLY APPLICABLE TO RAILWAY AND OTHER CARRIAGE WINDOWS."
My Invention relates to a novel method of raising, lowering, and fastening
windows, and is particularly applicable to windows, such as railway and other
carriage windows.
In applying my Invention to, say, a railway carriage window, I am enabled to
dispense with the ordinary lifting straps, also with the retaining or steadying side
springs now commonly used.
My Invention consists of a double bolt which is mounted in the top or on the
top of the sliding window frame or sash. The double bolt is carried on a duplex
lever, and is so arranged that upon the lever being worked, the bolts are drawn in
or driven out on each side of the sliding frame or sash respectively. The ends or
tips of the bolts are mounted with india-rubber buffers, which, when the bolts are
thrown out, bear against the main frame, and prevent the sliding frame from
moving, and also steady the sliding frame. The lever is operated by a suitable
handle fixed on the sliding frame or sash, which handle also serves for raising or
lowering the window, and by turning the handle the window is fixed in any
required position.
A modification may consist of dispensing with the india-rubber tips on the bolts
and substituting strips of india-rubber on the window frame against which the
bolts bear. To insure the bolts holding, the sides of the window frame may be
perforated, roughed, corrugated, or otherwise indented to receive the bolts.
A second modification consists in working the bolts by means of having a right
and left-handed screw, formed respectively on the inner ends of the bolts, such right
and left-hand screws working into a barrel having right and left-hand female
screws to receive same, and such barrel being operated upon by a lever or handle,
or the same result may be obtained by double eccentric discs, or by levers which
work in slots.
In applying my Invention to the sliding sashes of ordinary house windows, I use
single bolts placed one at each side of the window, and provided with india-rubber
tips, and operated by a suitable lever or screw gear.
The beforegoing being the nature and objeet of my Invention, I will now proceed
to describe more in detail how the same may be carried out into practical effect,
and for that purpose I have hereunto annexed a Sheet of Drawings illustrative
thereof. Like letters and Figures marked thereon denote like parts throughout the
various views.
Figure 1 is an elevation of a portion of a railway carriage door and window with
my Invention applied thereto.
Figure 2 shows a modified arrangement of Figure 1.
Figure 3 is a second modification of Figure 1.
Figure 4 illustrates an apparatus constructed according to my Invention for
raising, lowering, and fastening windows.
Figure 5 is a modification of Figure 4.
Figures 6, 7, 8, and 9 are sections taken respectively through A, B, C, D,
Figura 5

page_text: Figures 10 and 11 illustrate another modification of apparatus according to my
Invention.
Figures 12, 13, and 16 are also modifications of my Invention.
Figures 14 and 15 illustrate the modification of my Invention as shown at
Figure 2.
Upon reference to the Drawings it will be seen that A is a portion of a railway
carriage door, B is the window, and E the window frame.
It will be seen that the ordinary lifting straps on the windows B are dispensed
with, and in lieu thereof there is provided a double bolt or lever a, a¹.
In Figure 4 the double bolt is shown carried upon a duplex lever b, which is worked
by the handle c. The arrangement is such that upon the handle c being turned,
the bolts a, a', are driven out on each side of the sliding frame or sash respectively.
The ends of the bolts a, a, are provided with india-rubber tips, such as d, or springs
such as e, so that when the bolts a, a, are thrown out, the rubber tips d or the
springs e bear against the main frame F, and prevent the sliding frame E from
moving, and also steady such sliding frame. The handle c, which works the levers
bor their equivalent, hereafter described, is fixed to and works on the sliding frame
E, such handle c serving for raising or lowering the window B, and by turning the
handle, and thereby throwing out the bolts a, a, the window is fixed in any
required position.
In the modification shown at Figures 2, 14, and 15, the bolts a, a¹, are shown as
levers, having their fulcrums on the pins k. This arrangement is illustrated in
detail in Figures 14 and 15. The bolts a, a', are selfacting, and from their position
allow the window to be raised by the handle c. Upon the window being released,
the levers a, a¹, come automatically into action and support the window.
Figures 2A, 2B, 20, illlustrate the raising and lowering handle c as adapted to the
arrangement shown at Figure 2. It will be seen that the plate carrying the handle
c is provided with a lever having its fulcrum at x. The lower end of the lever
is provided with a knob y, and the upper end with a catch z. The lever is kept
from the plate by a spring t.

In operation, the window is raised by the handle c, which action lifts up or raises
the bolts a, a'. Upon pressing the knob y, the catch is thrown out, and holds the
levers a, a, in position to allow of the window being lowered. Upon releasing the
knob Y, the spring t throws back the lever, and thereby the catch and the bolts
u, a¹, come automatically into action and support the window.
The modification, shown at Figure 3, consists of dispensing with the india-rubber
tips d on the bolts a, a, and substituting strips of india-rubber h on the window
frame F, against which the bolts a, a¹, bear.
In Figure 3, the bolts a, a, are shown as levers, having their fulcrum on the
pins k, the dotted lines show the working of this arrangement, which is further
illustrated by Figures 34 and 3B; the handle c is a fixture on the window frame E.
The bolts a, a, are selfacting. In raising the window, the bolts a, a¹, from their
position allow the operation of raising to be easily performed, and upon the
window being released, the points of the bolts a, a', slightly enter the india-rubber
strips has at a³, and thus secure the window. When the window is required to be
lowered, it must first be slightly raised, and the bolts a, a, held by pressing the
knob a, the window will then slide down freely.
In Figure 5, the bolts a, a, are worked by the duplex lever b operating the hooks
or gabs i, . The india-rubber tips d are inserted into the bosses p, which are
capable of adjustment, thus regulating the lengths of the bolts a, a¹, and thereby
the pressure on the window frame F.
It will be obvious that there are varied modified arrangements which will
effect the throwing out of the bolts a, a¹; for example, the double eccentric arrange-
ment r, shown at Figures 10 and 11, or the right and left-handed screw arrange-
ment w, shown at Figure 12.
The bolts a, a, are prevented from rattling by fitting strips placed over such
bolts, or by rings of india-rubber adapted thereto. The india-rubber tips d may be

page_text: inserted into the ends of the bolts a, a¹, or be placed on such bolts as caps in manner
such as shown at Figure 13; or the bolts a, a¹, may be used without the india-
rubber tips, in which case the bolts a, a¹, press against india-rubber strips h, such
as shown at Figures 3 and 16.
Having now described and particularly ascertained the nature of my said
Invention, and the system, mode, or manner in or under which the same is or may
be used or practically carried into effect, I would observe that the following, read
in connection with the accompanying Drawings, is what I consider to be novel and
original, and therefore claim as the Invention secured to me by the herein-before in
part recited Letters Patent,-
Firstly. I claim the method of raising, lowering, and fastening windows by means
of an apparatus consisting of two bolts, such as a, a¹, operated by a lever such as b,
such bolts being provided with india-rubber tips, such as d, springs such as e, or
pressing against india-rubber strips, such as h, as herein-before described and illus-
trated in the accompanying Drawings,
Secondly. I claim the method of securing or fastening windows, such as railway
carriage windows, by the direct outward pressure of two bolts, such as a, a¹,
whether such bolts be operated by a lever, such as b; a gab arrangement, such as i;
an eccentric arrangement, such as v; a double screw arrangement, such as w, or by
an automatic arrangement, such as shown at Figures 2, 3, 14, and 15.
Thirdly. I claim the use of india-rubber tips, such as d, or springs, such as c,
when applied to bolts for fastening or securing windows, as herein-before described
and shown in the accompanying Drawings.
In witness whereof, I, the said Hugo Worthington, have hereunto set my
hand and seal, this Third day of July, in the year of our Lord, One
thousand eight hundred and seventy-seven.
HUGO (L.S.) WORTHINGTON.
