Improved Spring Mattress.
WILLIAM DRYDEN GLEN 5 Maitland Street Edinburgh employed by D. & G. Glen
Cabinet Makers Upholsterers &c. as Salesman do hereby declare the nature of this
invention to be as follows :-
A wood portable frame made any size which is held together by iron bolts at
each corner & with a Sliding Cross Stretcher that can be tightened & loosened by
means of three bolts-Attached to this said Sliding Stretcher & bottom of frame
are several Spirel Springs securely fastened by iron hooks bolted through the wood-
The Springs are then connected to each other by wood laths that have small hooks
fastened at each end-The Laths are held together by two pieces of web and the
out-most laths have two of the Springs fastened to the side Stretchers by means of
Leather Straps.
To prepare for transit purposes loosen the three bolts of Sliding Cross Stretcher,
unhook the laths & side Springs then unbolt the frame-when it will be found to
go into the smallest possible bulk.

Improved Spring Mattress.
I, WILLIAM DRYDEN GLEN, of 5 Maitland Street, in the City and County of
Edinburgh, Salesman, do hereby declare the nature of my invention, and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement in writing, reference being had to the accompanying
Drawings and to the letters and figures marked thereon, that is to say :-
My Invention has reference to and comprises a strong wood portable frame to be
laid on the frame of the bed under the hair or other mattresses and made any size,
and is held together by iron bolts or screws at each corner, and with a sliding cross
stretcher that can be tightened or loosened by means of screw bolts. Attached to-
the fixed frame at the one end and at the other end to said sliding stretcher and
bottom of frame, are several spiral springs securely fastened by iron hooks bolted to
or through the wood. The springs are then counected to each other by wood laths,
that have small books fastened at each end. The laths may be held together by
two pieces of web, and the outmost laths may have two of the springs fastened to
the side stretcher by means of leather straps.
To prepare for transit purposes loosen the bolts of sliding cross stretcher, unhook
the laths and side springs, then unbolt the frame when it will be found to pack or
go into the smallest possible bulk.
And. in order that my said invention and the manner of performing or carrying
the same into effect or practice may be properly understood, I have hereunto appended
an explanatory Sheet of Drawings, in which the same reference letters are used to
indicate corresponding parts in all the figures where shown.
Figure 1 is a longitudinal edge section and Figure 2 a plan, the former taken on
the line 1--1 of the latter, of my new or improved construction of bed spring mattress.
Figure 3 is a transverse section of same, as taken on the irregular line 2--2 in
Figure 2; and Figures 4 and 5 illustrate to an enlarged scale, a side elevation and
plan view of the top end corner of the mattress and show the fittings of the sliding
cross stretcher or shifting board E, to which the one set of springs C, are attached.
Referring to these Drawings, the improved spring mattress is constructed of an
outer rectangular frame of wood made in four parts, two side rails A, and two end
:

page_text: rails A secured together at the ends on opposite sides by cheek plates A² preferably
screwed at a, to the side rails A, the end rails A' being checked in between these and
retained at each corner by one screw a¹, the removal of which separates these side and
end frames A A¹, but other equivalent or suitable means of securing these end frames
may be used. The upper parts of the side rails A1 are cut away to a considerable
depth nearly the whole length of the rails at A", between the iron cheek plates A².
The wood laths B are placed longitudinally and horizontally at short distances apart
within the upper part of the frame A A', and have swivelling hooks or eyes B¹ secured
by pins at each end, to which the eyes or inner ends of a set of spiral springs C and C¹
are attached, the outer ends of one set of these springs C. being attached to the hooks
of screw bolts D screwed into the inner upper face of the end rail A' at the one end
of the laths B and main frame A A¹, and the springs C, at the other end of the
laths B, are likewise attached by screw bolts D to a strong sliding transverse stretcher
rod or bar E at the other end of the frame A A¹. This stretcher bar E is preferably
made of wood and formed with retaining grooves at each end E¹ to fit into and slide
on wooden ribs or projecting parts E" screwed to the inner side of the side frames A A.
This stretcher bar E is attached to the one end frame A¹ and tightened or loosened by
two, three, or more screw_bolts E2 according to the width of the frame A A', passed
through holes in the bar E and end A' of the frame and fitted with screw nuts on the
outside of the frame A'. By tightening or loosening these screw bolts and nuts E2
and stretcher bar E, any desired regular tension can be imparted to the whole sets of
springs C, C, and corresponding elasticity or resilience given in the vertical direction
to the wooden laths B.
The main frame A A' is laid with its bottom edge on to the upper rails or frames of
the bedstead, and steadied by projecting plates a² screwed to the side rails A A, the
hair or other mattresses being laid on the top of the laths B, and free to move up and
down with the elasticity given to them by the springs, the recesses A" in the side
rails A allowing the mattresses to rise and fall also when made to project over the
frames A, A. This spring mattress frame A A¹, might in some cases be made the
bedstead itself, by screwing or otherwise securing feet under the four corners of
the frame as dotted in at A3 Figures 1 and 3. Girths or webs B2 of strong cloth may
in some cases or when desired be secured on the upper and lower sides of the laths B,
some distance from either end, and the ends of these girths might be attached to the
side rails A by elastic rubber or leather straps or springs at B, as shown dotted-in in
Figure 2. When desired the stretcher bar E may be dispensed with, and the springs C¹
be connected to the end rail A' as at the opposite end of the frame, preferably with
swivel eyes or hooks on the screws D to be able to tighten each up to the desired
tension by turning the screws. And although springs C, C¹, have been shown at both
ends of the laths B, one set of springs only might be used, with swivel links at the
other end; and although helical or spiral springs C, C¹, have been shown as used,
india-rubber or other springs might be similarly used to give the elasticity to the
laths B. And although the laths B have been shown as ranged longitudinally in the
frames A A³, they might be arranged and mounted in like manner transversely.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what
I claim is,
First. The construction, or arrangement and combination of the parts of a spring
mattress with horizontal laths fitted with springs, substantially as and for the purposes
herein described, in reference to and shown in the accompanying Drawings.
Second. The constructing of a spring mattress or frame, with horizontal latlis, and
end springs for giving resilience vertically to said laths, substantially as herein
described, in reference to and shown in the accompanying Drawings.
