Year: 1830

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH
HARRISON, of Wortley Hall, in the Parish of Tankersley, in the County of
York, Gardener, and RICHARD GILL CURTIS, of the same Place, Glazier, send
greeting.
WHEREAS His present most Excellent Majesty King William the Fourth
did, by His Letters Patent under the Great Seal of Great Britain, bearing
date at Westminster, the Sixth day of October, in the first year of His reign,
give and grant unto us, the said Joseph Harrison and Richard Gill Curtis,
His especial licence that we, the said Joseph Harrison and Richard Gill
Curtis, our exors, admors, and assigns, and such others as we, the said Joseph
Harrison and Richard Gill Curtis, our exors, adññiors, or assigns, should at any
time agree with, and no others, from time to time and at all times during the
term of years therein mentioned, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-upon-
Tweed, our Invention of "CERTAIN IMPROVEMENTS IN GLAZING HORTICULTURAL
AND OTHER BUILDINGS, AND IN SASH BARS AND RAFTERS, WHICH IMPROVEMENTS ARE
APPLICABLE TO OTHER PURPOSES;" in which said Letters Patent is contained a
proviso, that we, the said Joseph Harrison and Richard Gill Curtis, or one of
us, shall cause a particular description of the nature of our said Invention, and
in what manner the same is to be performed, to be inrolled in His said
Majesty's High Court of Chancery within two calendar months next and
immediately after the date of the said in part recited Letters Patent, as in and
by the same, reference being thereunto bad, will more fully and at large
appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, we, tho said
Joseph Harrison and Richard Gill Curtis, do hereby declare that the nature of
our snid Invention, and the manner in which the same is to be performed, aro
particularly described and ascertained in and by the Drawing hereunto
annexed, and the following description thereof (that is to say):-
The object of our improved manner or method of framing and glazing for
horticultural and other buildings and purposes is to obtain one nearly equal or
plane surface upon the upper side or face of glazed frames or sashes for stoves,
hothouses, greenhouses, conservatories, and other buildings, and also for hot
beds and other purposes, and to have no projecting parts above the surface of
the glass, the outer frame being of the size required, and rabetted or rebated to
receive the edges of the glass, and the inside being furnished with upright bars
of the size and number required, and having flat tops to them made even with
the bottom of the rebate of the frame for the glass to lie flat upon; the faces of
the bars, and the bottom of the rebate being then coated either with white
lead, ground in oil, or a thin bed of putty, or any other cement or material or
a mixture of materials fit and proper to make a water-tight joint, will be ready
to receive the glass. The glass should be cut of such a size as for the edges
to meet each other in the middle of the bars, and to be made to overlap a
little, in the usual manner of such glazing, but where cross bars are used tho
edges of tho glass must be so cut as to meet in the middle of them. In order
to secure the squares of glass in these frames or sashes we employ metal
screws and washers in the following manner :-In the annexed Drawing, Fig. 1
represents an outside view of a glazed frame or sash; Fig. 2, an edge or sido
view thereof; and Fig. 3, a cross section thereof. In all of these Figures the
same letters of reforence indicate the similar parts. A, A, the sash frame;
B, B, B, the upright bars; C, C, the squares of glass. In the angular
meetings of the squares, as at D, D, &c., Fig. 1, we introduce the metal
screws E, E, &c., with soft metal washers or collars F, F, &c. underneath
them, the screws being screwed into the wooden bars, as shewn in the section
of one of them, drawn on a larger scale in Figs. 4 and 5, one of the screws
being also shewn in a top and side view thereof to the same scale in Fig. 6,
and a washer or collar likewise shewn in a top and side view thereof in
Fig. 7, also on a similar scale. The squares of glass being cut to the proper
size, we proceed in the following manner :-Having bedded the lowermost row
of squares, either in a coat of white lead ground in oil, or a thin bed of glaziers'
putty, or in any other fit and proper water-tight cement or materials, spread
over the tops of the bars and around the bottom of the rebate in the frame, we
securo them at their lower meeting corners or angles by inserting a metal

page_text: screw E between the lower parts of the edges of each two adjoining squares,
and which, as above mentioned, is screwed into a hole accurately bored to
receive it in the middle of each bar B; having previously placed a soft metal
washer or collar F underneath the head of the screw, and also coated the
inside of the washer with the white lead in oil, putty, or other proper water-
tight cement or material, the screw may then be turned by means of the turn-
screw Fig. 8, the teeth in the edges of which are inserted into the gaps or
notches formed in the edge of the screw to receive them, and as shewn in
Fig. 6. The corners of the squares may be previously crumbled off in the
usual manner to make room for the screws if necessary, and the lower edge of
each washer or collar F may be turned down over the edges of the glass
squares to support them, and as shewn in the section Fig. 5 at F. In the
like manner the next row of glass squares may be imbedded, and their lower
edges be made to overlap the top edges of the first laid row, and be then
secured by screws and washers, in a similar way to the first row, and so on,
until the frame or sash may be completely glazed. In order to secure the
edges of the squares adjoining to the sides and top of the frame, we insert
small thin metal angularly-shaped pieces, similar to that shewn in Fig. 9, into
the sides and top of the rebate, by driving them in close to the surface of the
glass, so that the head of each piece of metal projects a little beyond the sides
and top of the rebate, and as shewn at G, G, &c. in Fig. 1, and in the section,
Fig. 3. In frames with cross bars the edges of the glass squares do not overlap of
course, but they are secured by means of metal screws with soft metal washers
or collars underneath their heads, in the manner above described, and likewise
in the edges of the rebates in the frames, by the angular metal pieces being
inserted above their surfaces. In this mode the upper side or face of these
sashes or frames will be nearly of an equal or plane surface, as above men-
tioned. In fact, with the exception of the trifling bendings in the glass squares
and the small projections of the screws and the washes or collars underneath
them, they may be said to be flat..
We have hitherto described our improvement as being applied to wooden
frames or sashes, but we can likewise adapt it to those made of metal by
having female screwed holes formed in their bars to receive our metal
screws into them, and likewise grooves in their sides for our angular pieces
of metal to enter; we can likewise occasionally employ screws with screw
nuts fitted to them, which may be passed through holes formed all through
the bars, and the nuts be bound upon them withinside of the frames or
buildings; they may be applied to our said improvements in sash bars and
rafters, consist in placing or affixing round or cylindrical metal bars or rods

page_text: at the bottom of the grooves in which the sashes slide for friction wheels
let into the sides of the sashes to run upon, and thereby to reduce the
rubbing or friction usually occasioned in moving such sashes. We do not
mean or intend.hereby to claim as our Invention any of the various methods of
glazing which have already been known or in use, but to limit our claims to
the securing of glass in saslics or frames with bars by means of screws and
washers or collars, so is to: proservo a nearly level or plane surface, and
without the use or. employment of putty above the glass, excepting the small
quantity thereof or of other water-tight materials whichí is placed underneath
the washers or collars; and although wo prefer to employ copper in the
formation of our screws and angular pieces, and lead in forming our washers or
collars, yet we do not mean or intend hereby to limit ourselves to the employ-
ment of those metals only, but to use any which may be fit and proper for such
purposes.
In witness whereof, I, the said Joseph Harrison, have hereunto set my
hand and seal, this First day of December, One thousand eight
hundred and thirty.
JOSEPH (Ls.) HARRISON.
AND BE IT REMEMBERED, that on the First day of December, in the
