page_text: LETTERS PATENT to Joseph Frazer, Silk Mercer, and William Naar;.
Upholsterer, both of Bayswater, in the County of Middlesex, for
the Invention of "IMPROVEMENTS IN THE. CONSTRUCTION OF MATTRESSES.
AND CAD Deno ""
Scaled the 2nd March 1869, and dated' tlie 15th December 1868..
PROVISIONAL SPECIFICATION left by the said Joseph Frazer and
William Naar at the Office of the Commissioners of Patents,,with.
their Petition, on the 15th December 1868.
We, JOSEPH, FRAZER, Silk Mercer, and WILLIAM NAAR, Upholsterer,.
both of Bayswater, in the County of Middlesex, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF
MATTRESSES AND CAMP BEDS" to be as follows:-
The chief object of this Invention is to provide for the adjustment, of
the upper surface of spring mattresses so as to set the head of the mattress
higher than the foot. To this end the mattress is made with a base and
an upper frame, which frames are connected together by the springs.
Applied to the ends of the frames are fastenings (straps and buckles or
their equivalent) for drawing the frames together so that the foot of the

page_text: mattress may be depressed and the head elevated at pleasure; also for
facility of packing the frames may be drawn together so as to reduce the
bulk of the mattress. The springs run along the sides and across the
middle of the mattress, secured to the wood of the base frame and to
tho wood and webbing of the top frame, and by this arrangement a
considerable economy in the number of the springs required to give the
mattress the required stiffness is effected. To convert the mattress into
a camp bed it is only necessary to screw short legs into the bottom or
base frame at the corners thereof.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Frazer and William Naar in the Great Seal
Patent Office on the 15th-June-1869..
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, JOSEPH
FRAZER, Silk Meroer, and WILLIAM NAAR, Upholsterer, both of Bays-
water, in the County of Middlesex, send greeting.
--WHEREAS -Her-most. Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of December, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Joseph Frazer and William Naar, Her special
licence that we, the said Joseph Frazer and William Naar, our executors,
administrators, and assigns, or such others as we, the said Joseph Frazer
and William Naar, our executors, administrators, and assigns, should at
any time agree with, and no others from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN THE CONSTRUCTION OF MATTRESSES AND CAMP BEDS,"
upon the condition (amongst others) that we, the Joseph Frazer and
William Naar, our executors or administrators, by an instrument in
writing under our, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months.
next and immediately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Joseph Frazer, on behalf of myself
and of the said William Naar, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following state-
ment, reference being had to the Drawing hereunto annexed, and to the
letters and figures marked thereon (that is to say) :-
The chief object of this Invention is to provide for the adjustment of
the upper surface of spring mattresses so as to set the head of thc
mattress higher than the foot. To this end the mattress is made with
a base and an upper frame, which frames are connected together by the
springs, and applied to the ends of the frames arc fastenings (straps
and buckles or their equivalent) for drawing the frames together so
that the foot of the mattress may be depressed and the head elevated at
pleasure.
In the accompanying Drawing Fig. 1 represents in plan view a
mattress constructed according to our Invention; Fig. 2 is a longitudinal
sectional elevation of the same; and Fig. 3 is an end view.
A, A, is the base frame; B, B, the upper frame; and O the coiled
springs interposed between them. On the under side of the upper
frame B webbing is strained to receive the stuffing or padding D of
horsehair, flock, or other suitable material which is placed on the
frame B. The canvas or other covering of this padding is continued
over the sides and ends of the frame B, and attached to the base frame A.
It thus closes the sides and ends of the mattress, leaving it at the same
time free to contract vertically at either or both ends, as will be presently
explained. The springs C, C, (sec Fig. 1.) are so arranged with respect
to the longitudinal and transverse bars of the upper and wer frames
that they may be said to stand between them, and they are secured to
the wood or iron of the base frame and to the wood or iron and webbing
of the top frame. By this arrangement a considerable economy in the
number of springs required to give the mattress the required stiffness
and elasticity is effected. Attached to the opposite ends of the upper
frame are straps E, E, fitted with metal eyelets, and corresponding
therewith on the lower frame are studs to receive the straps and hold
them at tension. If now it is desired to depress the foot of the mattress
and thus arrange it for reclining on it is only necessary to strain the
straps or their equivalent at the foot over their studs and secure them
thereto, as shown at Figures 2 and 3, the canvas or other flexible

page_text: covering at the sides and ends of the mattress folding inwards as the top
frame is depressed and offering no obstruction to the vertical contraction
of the mattress. An agrecable inclination upwards towards the head is
thus given to the mattress, which may readily be retained by increasing
the tension of the springs, which tension it will be understood may be
increased or diminished at pleasure by shortening or lengthening the
straps or their equivalent. For facility of packing the mattress for
transport the frames may be drawn together, whereby the bulk of the
mattress will be materially reduced. In order to convert the mattress
into a camp bed it is only necessary to screw or fit short legs into the 1
bottom or base frame at the corners thereof, which will require to be
made somewhat stronger than is indicated in the Drawing.
Having now set forth the nature of our Invention of "Improvements
in the Construction of Mattresses and Camp Beds," and explained the
manner of carrying the same-into-effect, we wish it to be understood 1
that under the above in part recited-Letters-Patent we claim, providing-
for the adjustment of the upper surfaces of spring mattresses and camp
beds in the manner and for the purpose above set forth.
-In witness whereof, I, the said Joseph Frazer, have hereunto set
my hand and scal, the Fifteenth-day of June, in the year of our
Lord One thousand eight hundred and sixty-nine.
