IMPROVEMENTS IN MATTRESSES
Year: 1885

page_text: DANIEL ROBERTSON GARDNER, 36 Jamaica Street, Glasgow, in the County of
Lanark, North Britain, Cabinet Maker, do hereby declare the nature of my
invention for the IMPROVEMENTS IN MATTRESSES to be as follows:-
The spring mattress consists of two cross wooden bars, each 4 inches broad
× 1 inches thick; the length being the breadth of the bed; one of these bars
is placed at the head and the other at the foot of the bedstead; on these cross
bars are firmly attached by staples, a row on each of them of ordinary upholsterers'
spiral springs; the upper surfaces of the springs are each covered with a layer
consisting of two pieces of girth web sewn together having strands of flexible
steel between them; this layer is sewed to the top of the springs and forms the
surface on which is placed a number of parallel laths, the section of each lath being
oval and about 2 inches broad × 1 inch thick and the length of the bed; these
laths are attached together about 2 inches apart by a row of girth web towards
each end, the girths being nailed to the laths. Leather straps and studs are now
used to fix the parallel laths to the cross bars; the studs are fixed, one on each
end of the cross bars; the straps are nailed to the outside parallel laths, just over
the studs, and when buttoned together, forms a spring surface for the stuffed
mattress to lay on.
The stuffed mattress has a section of cork at the borders; the tick is lightly
coated with melted or dissolved wax, then it is subjected to heat above the melting
point of the wax in an ordinary stove; then when dry it is rubbed or sort of
masticated which renders the tick permeable to air and resistant to water. The
wood leather & girth web is likewise treated, forming a preservative and rendering
the whole non-absorbant, becomes water as well as damp proof.
The parallel laths of the spring mattress can be buckled to the stuffed mattress
above, and as ship mattresses, become an auxiliary in forming life saving rafts, as
any number may be buckled together.
What I now claim as new and original is the mattress in whole or in part, with
the exception of the section of cork at the borders of the stuffed mattress.

page_text: DANIEL ROBERTSON GARDNER, 36, Jamaica Street, Glasgow, in the County of
Lanark, North Britain, Cabinet Maker do hereby declare the nature of my
invention for the IMPROVEMENTS IN MATTRESSES and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
inches
The spring mattress consists of two cross wooden bars (1), each 4
broad x1 inches thick; the length being the breadth of the bed; one of these
bars is placed at the head and the other at the foot of the bedstead; on these
cross bars are firmly attached by staples, a row on each of them of ordinary
upholsterers' spiral springs (2); the upper surfaces of the springs are each covered
with a layer, consisting of two pieces of girth web sewn together, having strands
of flexible steel between them (3); this layer is sewed to the top of the springs
and forms the surface on which is placed a number of parallel laths (4), the section
of each lath being oval and about 2 inches broad x 1 inch thick and the length of
the bed; these laths are attached together about 2 inches apart, by a row of girth
web (5) towards each end, the girths being nailed to the laths. Leather straps
and studs (6) are now used to fix the parallel laths to the cross bars; the studs are
fixed, one on each end of the cross bars; the straps are nailed to the outside
parallel laths, just over the studs, and when buttoned together, forms a spring
surface for the stuffed mattress to lay on.
The stuffed mattress (7) has a section of cork at the borders; the tick is lightly
coated with melted or dissolved wax, then it is subjected to heat above the melting
point of the wax, in an ordinary stove; then when dry, it is rubbed or sort of
masticated which renders the tick permeable to air and resistant to water. The
wood, leather & girth web is likewise treated, forming a preservative and rendering
the whole non-absorbant, becomes water as well as damp proof. The parallel
laths of the spring mattress can be buckled (8) to the stuffed mattress above, and
as ships' mattresses, become an auxiliary in forming life saving rafts, as any number
may be buckled together.
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 The oval laths with their arrangements and attachments to the spiral
springs.
2nd The arrangements and attachments of the oval laths to the stuffed mattress,
so as to form life saving rafts.
3rd The rendering of tick, wood, leather, and girth web, preserved from rot,
resistant to damp and water, and at the same time, permeable to air.
