Year: 1883

page_text: LETTERS PATENT to John Garlick of Saltley Works, Birmingham, in the
County of Warwick, Builder, for an Invention of "IMPROVEMENTS IN THE
CONSTRUCTION OF FLOORINGS, PLATFORMS, DADOS TO WALLS, FRAMINGS OF
DOORS, AND LIKE STRUCTURES OF WOOD
"
PROVISIONAL SPECIFICATION left by the said John Garlick at the Office
of the Commissioners of Patents on the 23rd May 1883.
JOHN GARLICK of Saltley Works Birmingham in the County of Warwick
Builder "IMPROVEMENTS IN THE CONSTRUCTION OF FLOORINGS, PLATFORMS, DADOS
TO WALLS FRAMINGS OF DOORS AND LIKE STRUCTURES OF WOOD
"
My Invention has for its object to so construct floorings platforms dados to walls,
framings of doors, and like structures of wood, in such a manner that comparatively
thin and consequently cheap layers or pieces of a relatively expensive wood can be
combined with less expensive wood in the said construction-According to my
said Invention I take strips pieces or planks of the wood (say oak or teak for
example) to form the upper surface of the floor and strips pieces or planks of the
wood (say deal for example) to form the underpart or support for the upper
surface-In the under part of the upper portion I form longitudinal projections.
recesses or grooves in the direction of the grain and in the upper part of the under
portion I form corresponding projections recesses or grooves so that the two parts
will fit together the projections recesses or grooves of the one part fitting into
those of the other-I then glue or cement the two parts firmly together-The
sides of the compound flooring boards thus constructed are preferably furnished
with engaging ribs and grooves which are interlocked with each other when the
flooring boards are laid together-In this manner I can produce from small pieces
of expensive wood which would otherwise be too thin for the purpose, a solid firm
and cheap flooring the component parts of which are firmly attached together and
constitute for all practical purposes a floor equal to one made from thick and
valuable pieces or planks of the expensive wood

by the said John Garlick in the Great Seal Patent Office on the 16th November
1883.
JOHN GARLICK of Saltley Works Birmingham in the County of Warwick
Builder "IMPROVEMENTS IN THE CONSTRUCTION OF FLOORINGS, PLATFORMS, DADOS
TO WALLS, FRAMINGS OF DOORS, AND LIKE STRUCTURES OF WOOD".
My Invention has for its object to so construct floorings platforms dados to walls
framings of doors and like structures of wood in such a manner that comparatively
thin and consequently cheap layers or pieces of a relatively expensive wood can
be combined with less expensive wood in the said construction. According to my
said Invention I take strips pieces or planks of the wood (say oak or teak for
example) to form the upper surface of the floor (for example) and strips pieces or
planks of the wood (say deal for example) to form the underpart or support for
the upper surface-In the under part of the upper portion I form longitudinal
projections recesses or grooves in the direction of the grain and in the upper part
of the under portion I form corresponding projections recesses or grooves so that
the two parts will fit together, the projections recesses or grooves of the one part
fitting into those of the other I then glue or cement the two parts firmly
together the sides of the compound flooring boards thus constructed are preferably
furnished with engaging ribs and grooves which are interlocked with each other
when the flooring boards or the like are laid together,
And in order that my said Invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the
figures on the annexed sheet of drawings the same letters of reference indicating
corresponding parts in both the figures.
Figure 1 represents in perspective a portion of a flooring constructed in
accordance with my Invention-Figure 2 is a longitudinal section on the line 1. 2.
The parts marked A represent the strips pieces or planks of the more valuable
wood to form the upper surface of the floor and the parts marked B represent the
strips pieces or planks of the less expensive wood. In the under part of the
portions A. I form longitudinal projections recesses or grooves (as shewn at a) in
the direction of the grain unless the wood be of a nature which will give sufficient
strength if the grain be not followed-In the parts B I form corresponding recesses
grooves or projections (as shewn at b) which in most or all cases should follow the
direction of the grain as most or all of the cheaper woods suited to the purposes of
my Invention have a straight or nearly straight grain which if cross cut would be
too weak to give sufficient hold. I glue or otherwise cement or attach the parts A
and B together as shewn. The said boards are preferably interlocked with each
other at the sides by ribs and grooves as at c. In this manner I can produce from
small pieces of expensive wood which would otherwise be too thin for the purpose
a solid firm and cheap flooring the component parts of which are firmly attached
together and constitute for all practical purposes a floor equal to one made from
thick and valuable pieces or planks of the expensive wood. I do not limit myself
to the number or shape of the grooves or recesses and projections in the parts A
and B as it will be evident that they may be varied without departing from the
nature of my Invention. It will also be evident that the ribs and grooves c may
be dispensed with and that the upper parts A may be made up of a number of
small lengths or pieces of the more valuable wood or of continuous pieces as shewn
but the under parts B will preferably be as long as convenient so as to give the
requisite strength: it will be readily understood that dados for walls framings of
doors or other like structures of wood may be constructed in a like manner.

page_text: Having now described and particularly ascertained the nature of my said Invention
and the manner in which the same is or may be used or carried into effect I would
observe in conclusion that what I consider to be novel and original and therefore
claim as the Invention secured to me by the hereinbefore in part recite Letters
Patent is
The construction of compound floorings, platforms, dados to walls, framings of
doors, and like structures of wood, substantially as hereinbefore described.
In witness whereof I the said John Garlick have to this my Specification set my
hand and seal this thirteenth day of November One thousand eight hundred and
eighty three.
