Improvements in Winch Handles or Keys for Adjusting Mattress
Surfaces and for other purposes.
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 to be as
follows:-
:-
Our said invention relates generally to winch handles or keys for turning screws
or other bodies and particularly to the winch handles or keys used for turning the
screws whereby the surfaces of elastic metallic and other mattresses are adjusted.
The handles for this latter purpose are usually of cast iron and are liable to being
easily broken by an accidental fall or by rough usage or by ordinary use. Forged
handles or malleable cast would of course be more durable but their cost is too
considerable. By our invention we propose to unite the strength of a forged
handle with the cheapness of cast metal. For this purpose we make the part or
box which engages with the screw or bolt head of cast iron and preferably of cast
malleable iron. When so made we bore or core it to receive the end of a cranked
wrought iron bar which forms the handle. The cranked bar is driven, screwed or
otherwise secured in or to the cast malleable box and the handle is thus complete.
The box might be made of ordinary cast iron and be cast upon the wrought iron
portion of the handle. A straight bar of wrought iron instead of a cranked bar
might be secured to or incorporated with the cast box forming a key instead of a
winch handle. A tee shaped handle of wrought iron might also be connected or
cast to the end of the box, thus forming a box-key. By means of our invention
we produce a winch handle or key which is light, cheap strong and practically
indestructable. Our improved winch handle or key might be used not only for the
purpose more particularly specified but also generally for other purposes for which
such handles or keys are applicable.

Improvements in Winch Handles or Keys for Adjusting Mattress
Surfaces and for other purposes.
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 ascer-
tained in and by the following statement and accompanying drawings:
Our said invention relates generally to winch handles or keys for turning screws
or other bodies and particularly to the winch handles or keys used for turning the
screws whereby the surfaces of elastic metallic and other mattresses are adjusted.
The handles for this latter purpose are usually of cast iron and are liable to be
easily broken by an accidental fall or by rough usage or by ordinary use. Forged
handles or malleable cast would of course be more durable but their cost is
too considerable.
By our invention we propose to unite the strength of a forged handle with the
cheapness of cast metal." For this purpose we make the part or box which engages

page_text: with the screw or bolt head of cast iron and preferably of cast malleable iron. In
combination therewith we use a cranked or other handle of wrought iron, screwed,
rivetted, cast, or otherwise attached to the aforesaid cast box or portion for
engaging with the bolt head or nut.
In order to make our said invention clearly understood we have attached
hereunto a sheet of drawings which clearly illustrate the construction of the
improved handle.
Fig. 1 is a perspective view of a winch handle made in accordance with our
invention.
Fig. 2 is a section of the cast box or portion to engage with the bolt head or
nut the section clearly showing the insertion of the wrought iron handle.
The cast box or portion to receive and engage with the bolt head or nut, is
marked a. The wrought iron portion forming the cranked handle is marked b.
The portions a and b might be united in a variety of manners. In the drawing
we have intended to represent the cast box,a as bored and countersunk to receive
the reduced tail of the cranked handle . The handle is rivetted in position thus
forming a secure union with the box a. The handle might however be driven,
screwed, pinned or otherwise fixed in position; or the box a might be cast or
shrunk upon the handle. The box a might be of cast iron but preferably we make
it of cast malleable iron for the sake of added strength and lightness. It will be
evident that the bar a might be straight instead of cranked thus forming a key
rather than a winch handle.
Also a tee shaped handle might be connected by
any of the aforesaid means to the end of the cast box or portion a thus forming a
box key as indicated by the reduced perspective sketch Fig. 3.
"
Although we have referred to the box or portion a as composed of cast or cast
malleable iron it might be made of any other suitable metal which will cast. The
handle also instead of being of wrought iron as described might be of any other
suitably tough and strong metal.
By means of our invention we produce a winch handle or key which is light,
cheap, strong, and practically indestructable.
Our improved winch handle or key might be used not only for the purposes
more particularly specified but also generally for other purposes for which such
handles or keys are applicable, for example it might be used for turning winches
for hoisting and hauling.
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 -
The improved winch handle or key formed by the combination of a cast box or
portion a for engaging with the bolt head or nut or other body to be turned and a
straight, or cranked, or tee or other shaped bar or handle of wrought iron or
other sufficiently tough or strong metal secured to the said bar or. portion a or
having the said box or portion cast or shrunk thereon, the whole constituting a
light, and strong handle or key substantially as described and shown.
