I HENRY CHANCELLOR, of 5 Ruskin Street Park Town Battersea, South
Lambeth, Pattern Maker and Draughtsman do hereby declare the nature of my
invention for HOLDING THE WINDOW OF ANY CARRIAGE ETC IN ANY DESIRED
POSITION AUTOMATICALLY to be as follows:-
That toothed racks be fitted to window-frame (that is one each side) into which
works a catch or holder. These are connected by a rod (covered with a wood
roller) screwed tightly in. On this same catch or holder an india rubber brake is
fixed which is brought into use upon the release of the window, which allows the
window to gradually slide downwards to any distance determined upon by the
user-When raising the window it catches or holds it automatically, likewise upon
the release of the same These holders or catches are hung upon pivots which are
carried by brackets fixed to door There are slotts through door to accomodate the
catches or holders. The door itself forming the stop or guide.

I, HENRY CHANCELLOR of 23 Shirley Grove, Battersea in the County of Surrey,
Pattern-maker and Draughtsman do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
That toothed or notched racks (a, a,) be fixed to window sash or moveable
panel (b), into which are introduced catches, holders, or fasteners (c, c.). These
catches, holders, or fasteners, are provided with a brake, (d, d,) and are hung upon
pivots or centre pins; carried or supported by brackets (e, e,) fixed to door or
frame (ff), and are connected by a rod (g) covered with a tube or wood covering (h)
which forms the handle for releasing the window, or other object held.
When raising the window or other object in the ordinary way, the catches
holders or fasteners are brought into action, and by the force of gravitation take
their place in the racks, and holds the object at the height to which it has been
raised.
When releasing the window or other object (b) the handle, by being pressed
toward the window or other object held, releases it and simultaneously with this
movement the brakes are brought into action, and prevents the sudden fall of the
window or other object, but allows it to slide down (the brakes revolving) to any
point desired and upon ceasing to press the handle, the window or other object is
held, or still pressing the handle it slides down to the bottom.
Slots (i) are required to be cut to the depth of groove (2). only, in stiles of
door (f) for the catches, holders, or fasteners: also through lining or paneling (k)
for the brakes.
The window can be lifted into its usual position (6) for running the rain off.
Its fixed position as to height is not compulsory, as it may be so raised, that the
handle shall form a barrier, answering the purpose of that usually fixed across
window openings.
The door or frame forms the stop or guide when using the appliance.
By fixing the appliance to the meeting-rail of any bottom sash, it not only forms
a holder for top sash, but likewise locks both sashes together, when at their
extremeties, or when closed.
The holders, catches, or fasteners can be detached and used singly by making the
brackets forked, or double brackets with the holder, catch or fastener banging in
the centre of bracket.
When it is inconvenient to use the framework as the stop or guide: the stop
or guide can be cast on brackets, and projecting sufficiently forward, can be utilized
to support catch, holder, or fastener.
In single windows or moveable panels, such, and including those used at Enquiry,
Booking, or other offices; it not only holds the window in any desired position
(dispensing with sash weights etc) but by inverting one of the racks and one
fastener, detached from rod or un-detached, it forms a holder and fastener.

page_text: When combined or attached by rod it forms a holder and fastener at one and
the same time, as they are together in gear, or out of gear as the case may be:
or used doubly.
When using them singly, it would be necessary to put the fastener out of gear,
before the window could be raised.
By inverting the apparatus, the handle still hanging below the point of fixture,
(viz) (the catch or fastener inverted in respect to its position with the handle) and
a double fastener is the result: only the handle would be pulled toward the operator
to release it, instead of pressing it toward the object fastened.
The distance between pivot or hanging centre and point of holder or fastener,
likewise between hanging centre and point of brake contact, so also depth and
pitch of tooth or notch and the amount of brake power required, are variable
according to circumstances.
In all cases where an attempt is made to force the window or other object (held
or fastened) so the tighter does it become.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
1st That it is an effectual means for holding and fastening, automatically, the
window or other moveable panel of any railway-carriage, road carriage or other
vehicle: dwelling house windows, Enquiry, Booking or other office windows or
panels, without altering the window, panel, or frame-work as to its construction.
2nd That by inverting one rack and one holder, it is a holder and fastener
combined.
3rd That by inverting the holders and racks bodily, (with the position of the
fasteners in respect of the handle) it forms a double fastener.
4th That they can be used separately or combined, or as double fasteners and
holders.
5th That the lengths between centres; teeth with their depth and pitch; and the
amount of brake power required, are matters to be determined upon by the
necessities of the case.
6th That the positions for fixing the appliances are not compulsory, but may be
varied.
7th The manner and method of holding, arresting, releasing, and fixing or
fastening, any window, panel, or other object.
Dated this 10th day of February 1886.
