PROVISIONAL SPECIFICATION.
Improvements in the Construction of Mattress Frames.
We ISAAC CHORLTON of 19 Blackfriars Street Manchester in the County of
Lancaster Spring Mattress Manufacturer and GEORGE LAMB SCOTT of the same
place Engineer do hereby declare the nature of our invention to be as follows:-
Our said invention has reference to improvements in the mode of connecting the
end angle or other bars of elastic metallic mattresses made of woven wire or of
links, chains, laths and the like in combination with or apart from springs as is now
well understood. The invention is applicable more especially to mattresses made to
be adjustable as regards their tension by a sliding or movable end bar or end bars
the said movable end bar or bars being carried in blocks traversing on slides and
operated by adjusting screws. We have found that such mattress frames are
frequently deficient in rigidity and that when being handled or standing in store or
in positions other than when lying on a flat surface they become easily distorted
and unsightly. In addition to this the sliding adjusting blocks being usually
separate from the end bars are frequently lost and mislaid.
The chief objects of our invention are to impart greater rigidity to the mattress
frame and also to obviate the possibility of losing these separate adjusting carrier
blocks. In carrying the improvements into effect we firmly attach the angle iron
end to the adjustable carrier blocks by means of bolts, screws, rivets or the like
which bind the end bars firmly to the blocks. To provide more extended contact
surfaces we may form the blocks with extension pieces against which the angle ends
bear so as to increase the rigidity and more effectually prevent working of the
parts. The adjusting screws pass through the angle irons and engage with
the blocks. The blocks are preferably cast with lips or flanges at the outer
sides which box in and mask the angle iron ends and not only confer an improved
appearance upon the mattress frame but also assist greatly in rendering the frame
more rigid. By preference we make the blocks at both ends and also the slides
of malleable cast iron as we thus gain increased lightness and strength. We have
found it of advantage to form the slide portions and the end brackets separate from
each other instead of in one piece as formerly.

Improvements in the Construction of Mattress Frames.
We ISAAC CHORLTON of 19 Blackfriars Street Manchester in the County of
Lancaster Spring Mattress Manufacturer and GEORGE LAMB SCOTT of the same
place Engineer do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement and accompanying drawings:
Our said invention has reference to improvements in the mode of connecting the
end angle or other bars of elastic metallic mattresses made of woven wire or of
links chains laths and the like in combination with or apart from springs as is now
well understood. The invention is applicable more especially to mattresses made
to be adjustable as regards their tension by a sliding or movable end bar or end
bars the said movable end bar or end bars being carried on blocks traversing on
slides and operated by adjusting screws.
We have found that such mattress frames

store or in positions other than when lying on a flat surface they become easily
distorted and unsightly. In addition to this the sliding adjusting blocks being
usually separate from the end bars are frequently lost and mislaid.
The chief objects of our invention are to impart greater rigidity to the mattress
frame and also to obviate the possibility of losing these separate adjusting carrier
blocks. In carrying the improvements into effect we firmly and permanently attach
the angle iron ends to the adjustable carrier blocks by means of bolts screws rivets
or the like which bind the end bars firmly to the blocks.
To provide more extended contact surfaces we may form the blocks with
extension pieces against which the angle ends bear so as to increase the rigidity
and more effectually prevent working of the parts. The adjusting screws pass
through the angle irons and engage with the blocks. The blocks are preferably cast
with lips or flanges at the outer sides which box in and mask the angle iron
ends and not only confer an improved appearance upon the mattress frame
but also assist greatly in rendering the frame more rigid. By preference we
make the blocks at both ends and also the slides of malleable cast iron as we
thus gain increased lightness and strength. We have found it of advantage to
form the slide portions and the end brackets separate from each other instead
of in one piece as formerly.
To render our invention more easily understood we will now proceed to describe
the same particularly with reference of the accompanying drawings.
Fig. 1 shows a portion of the wooden side of a mattress frame carrying an
adjustable bracket and slide made in accordance with our invention.
Fig. 2 is a similar view of the non-adjustable end.
Fig. 3 is a back view of the sliding bracket carrying a portion of the angle iron
end.
Fig. 4 is a plan of Fig. 1.
Fig. 5 is a separate perspective view of this sliding bracket clearly showing the
extension to assist in carrying the angle end.
Fig. 6 is a separate perspective view of one of the fixed end brackets through
which the adjusting screws pass.
Fig. 7 is a perspective view of the slide bracket carrier which as has been said
is formed separately from the fixed end bracket.
We have choosen to represent our invention in conjunction with a mattress frame
having wooden sides and metallic angle ends but the invention is also either wholly
or mainly applicable to mattress frames having tubular or other metallic sides as
will be well understood.

.
In the example illustrated the end brackets a at the adjustable end of the mattress
frame (see Fig. 1) and also the end brackets 6 at the fixed end of the mattress
frame (see Fig. 2) are mounted upon the wooden side c and secured thereto in the
improved manner and by the improved means fully described in the Specification
attached to our previous Patent No. 1581 of 1889 viz. by bolts d which enter
tee" shaped recesses in the foot of the brackets and pass through the side being
secured by nuts d' as clearly shown. The sliding brackets e of which there is one
at each side of the mattress frame and which together carry the angle iron or steel
end is formed in all respects as heretofore with two exceptions. In the first place
we cast an extension-e-at-the inner side-of the-bracket e so that the area of the
face against which the vertical web of the angle end rests is largely increased and
therefore the security of the connection between the two surfaces is augmented.
Generally speaking the brackets e have hitherto been so arranged that the angle
ends are connected thereto either by removable screws or bolts or by means of
snugs or projections.
According to our invention we firmly and permanently rivet the angle end f to
the brackets e for example by means of the two rivets gh or by any other suitable
number of rivets. By thus firmly and permanently connecting the brackets e (with
extensions e¹) to the angle ends we render the mattress frame as a whole much more

page_text: stiff and rigid than is the case with the usually more restricted surface contact and
less firmly securing means. As the brackets e are also permanently connected to
the angle ends f there is no danger of the brackets being lost as is very likely to
happen when they are separate from the ends. In addition to the extension e¹
another feature of the improved bracket e is that it has a projecting lip at the
outside which rises to the level of and completely boxes in the extremity of the
angle end as is apparent for example in Fig. 1. This boxing in of the angle end
confers a much neater and more finished appearance upon the mattress frame when
viewed from the side. The lip e² also acts as a stop and prevents any possibility of
end-on working of the angle end especially where it is used in conjunction with non-
permanent fastening means for securing the angle ends to the brackets. The
perspective view of the bracket e shown at Fig. 5 clearly illustrates both the
extension e and the lip e². It will be understood that the fixed end bracket b is or
may be likewise provided with a similar extension and a similar lip. The non-
adjustable angle end i may be rivetted to the brackets in the same manner that
the end fis rivetted to the brackets e or they may be secured by other more easily
removed or less permanent means.
We
Hitherto at the adjustable end of the mattress it has been the custom to cast the
slide k which carries the sliding bracket e in one piece with the bracket a.
have however found that owing to this unyielding connection the slide frequently
breaks at the point of its union with the bracket a. To obviate this breakage we
cast the bracket a and the slide k separately as for example shown in Figs. 6 and 7.
By this means undue relative strain between the parts is avoided. The separate
slide k is attached by screws at the points k¹ k'. To obtain a due combination of
lightness and strength we prefer to make the castings of malleable cast iron.
The bracket e is traversed to and fro on the side k by the screw arranged as
shown.
In carrying our invention into effect we may use the whole of the improved points
or features herein before specifically alluded to in combination or we may use them
singly and apart from one another as none of the several improvements are
absolutely dependent upon each other. For example we might use the improve-
ment relating to the slide and bracket without modifying the sliding or fixed
brackets e and b or mode of connection to the angle ends or we might use the
improvements relating to the said brackets without making any change in the fixed
slide brackets.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
1. In a mattress frame having fixed and adjustable ends forming the brackets
which carry the angle end with extensions so as to provide greater area of contact
between the angle ends and the brackets and permanently securing the angle ends
thereto by means of rivets screws or the like for the purposes and substantially as
described and shown.
2. Forming the end brackets whether sliding or fixed which carry the angle ends
with lips or ledges which box in and conceal the extremities of the angle ends
substantially as described and shown.
3. Forming the slide portion k separate from the end bracket a for the purposes
and substantially as described and shown.
