I, MATTHEW JAMES ROWCLIFFE Cabinet Maker of 9 Richmond Buildings Soho
Square, in the County of Middlesex do hereby declare the nature of said
invention for AN IMPROVED MEANS OF AND APPARATUS FOR SUPPORTING AND
FIXING AT ANY REQUIRED HEIGHT VEHICLE WINDOWS MUSIC STANDS AND READING
DESKS AND OTHER ARTICLES HAVING A LIKE MOVEMENT to be as follows:-
This invention relates to improvements in the apparatus described by me in my
provisional specification Numbered 2946 and dated 8th February 1884 and in my
complete specification bearing the same number. By tuy present improvements
the parts are simplified and rendered suitable for supporting and fixing at any
required height vehicle and other windows music stands reading desks and other
articles of furniture or of building having the like movement. To carry out my
present improvements I affix a strip of metal down the entire length of the
inovcing part of the article to which they are to be applied and in the fixed part of
such article as in the frame of the window I let in at any convienient height so us
to open against the aforesaid strip of metal; a box shaped cavity similar to that
described in the above mentioned specifications but having tho cavity wider at
the top than at the bottom instead of the reverse as therein described. In this
cavity I place a metal cylinder or sphere of any convienient size which is capable
of being lifted up by the end of a bell crank or other lever fixed in the wood
work of the article and connected at the other end with a projecting knob or
similar device. The window or other article to which the invention has been
applied has only to be raised to the desired height and then released when it will
be firmly fixed because in commencing to fall the cylinder or sphere becomes
jammed between the metal strip of the window or other article and the sloping
face of the cavity. To alter the height it is only necessary to touch the projection
so as to raise the end of the lever and thereby release the cylinder or sphere when
the window or other article can be moved up and down as required.

I, MATTHEW JAMES ROWCLIFFE Cabinet Maker residing at 9 Richmond
Buildings Soho Square London W in the County of Middlesex do hereby declare
the nature of my invention for AN IMPROVED MEANS OF AND APPARATUS FOR
SUPPORTING AND FIXING AT ANY REQUIRED HEIGHT VEHICLE WINDOWS MUSIC
STANDS AND READING DESKS AND OTHER ARTICLES HAVING A LIKE MOVEMENT
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
This invention relates to improvements in the apparatus described by me in the
specifications for which Letters Patent N° 2946, A.D 1884 were granted to me.
By my present improvements" the parts are simplified and rendered suitable for
supporting and fixing at any desired height railway carriage or any other kind of
vehicle or other windows, music stands reading desks and other articles of
furniture or building having a like movement To carry out my present improve-
ments I affix a strip of metal down the entire length of the moving part of.the
article to which they are to be applied and in the fixed part of such article as in
the frame of a window I let in at any convenient height so as to open against the
aforesaid strip of metal a box shaped cavity, similar to that described in the
specifications above mentioned but with the cavity wider at the top than at the
bottom instead of the reverse as therein described. In this cavity I place a metal
roller cylinder or sphere of any convenient size which is capable of being lifted
up by one end of a bell crank or other lever fixed in the wood work of the article
and connected at the other end with a projecting knob or similar device. The
window or other article to which the invention is applied has only to be raised to
the desired height and then released when it will be firmly fixed because in
commencing to fall the roller becomes jammed between the metal strip of the
window or other article and the sloping face of the cavity. To alter the height
it is only necessary to touch the projection so as to raise the further end of the
lever and thereby release the roller, when the window or other article can be
moved up or down as required.
'
And in order that my invention may be more clearly understood I have appended
hereto a sheet of drawings shewing two modifications of my invention as applied
to a carriage window.
Fig 1 is an elevation in section of a portion of a railway carriage window
shewing the improvements applied thereto, and
Fig II is a section at right angles to Fig I along X Y.
A is the sash having the metal strip B attached. D is the cavity shape. as shewn
lined with metal C cut out of the door frame E. The metal cylinder F rests on
the end of the lever G pivotted at H and I and actuated by pressing in the
projecting push K. L is a brass plate let into the frame and having a guard M for
the protection of the push K. and, to the back of which the lever G is pivotted
at E. O is a spring to keep the lever G down. By pressing in the push the

page_text: lever G raises the cylinder F into the larger part of the cavity D and so allows
the window to be raised or lowered, but on ceasing to push, the spring O presses
the lever down when the cylinder F falls and grips firmly and instantly the side
B of the sash and the opposite side of the cavity.
Fig III represents a front elevation partially in section of a railway carriage
window shewing another method of applying my invention, similar letters being
used to indicate corresponding parts in the different figures. The figure shews the
window half up and half down out of sight.
A is the sash having metal strip B. E is the door frame out of which is cut
the cavity D shape as shewn lined with metal C. K is a knob projecting into the
carriage attached to a pin working in a slot P in the garnish rail fastened to the
end of the lever G pivotted at H at the other end of the lever is a pin which
passes into the center of the cylinder or roller F which latter works in the cavity D
and is kept down by means of the spring O pressing on the end of the lever G.
This method of attaching the lever to the roller I find most convenient as it
prevents the latter getting out of the cavity under any circumstances.
"
I am aware that india rubber and other similar wheels and rollers have
been employed at different times in connection with railway and other windows
I therefore desire to state that I do not claim generally the use of rollers or wheels
in connection therewith. The essential features of my invention being the use of
a hard unyielding roller or cylinder working in a cavity larger at the top than at
the bottom and holding the moving part of the object securely by jambing between
one side of it and the face of the cavity with means for moving the roller from its
position, and it will be readily understood that the details may vary somewhat
according to the circumstances under which the invention is applied the principle
remaining the same.
By the word metal throughout this specification I desire to include metal and
any substitute therefor which might be used in the above invention as Ivory,
boxwood, Ebony &c although at the present time I prefer metal and consider it
preferable to anything else.
Having now particularly described and ascertained the nature of my snid
invention and in what manner the same is. to be performed I declare that what
I claim is
. I In apparatus for supporting and fixing at any required height vehiclo windows,
music stands, and reading desks and other articles having a like movement the
combination of the cavity D with the metal lining C, metal cylinder roller or
sphere F and metal strip B substantially as described...
II In apparatus for supporting and fixing at any required height vehicle
windows, music stands, and reading desks, and other articles having a like move-
ment the combination of the cavity D with the metal lining C, metal cylinder
roller or sphere F, and metal strip B with means for actuating the same substantially
as described and illustrated in Figs I and II of the annexed sheet of drawings.
III In apparatus for supporting and fixing at any required height vehicle
windows, music stands and reading desks and other articles having a like move-
ment the combination of the cavity D with the metal lining C, metal cylinder
roller or sphere F, and metal strip B with means for actuating the same substantially
as described and illustrated in Fig III of the annexed sheet of drawings.
