I, WILLIAM MUNRO GREEN, of 48, Mair Street, Paisley Road, Glasgow, Lanark-
shire, Engineer, do hereby declare the nature of my invention to be as follows:-
This invention has reference to and comprises improvements in belts for the cure
of spinal weakness, by which such belts are rendered more efficacious, and when
used for growing young persons are capable of adjustment to suit their growth,
thus obviating the necessity of renewing the belts.
According to my improvements the belt is made in two parts connected at each
side by toggle link joints capable of being expanded and contracted by means
of a screw.
One part of the belt is formed to fit around the body, padded and recessed
to fit over the hips and be held in position there by straps and buckles. The
other part is formed to fit under the arm pits in a similar manner.
These two parts are connected together at each side by toggle links formed by
a pair of levers jointed together and pivotted or connected one to each part of
the belt and connected by another pair of levers jointed at their outer ends,
and each pivotted on one of the main levers. The main levers are preferably
formed at the pivotted end broad and finished of a semi-circular shape and rest
in corresponding shaped metal lined sockets or recesses secured to the belts and
preferably also pivotted there.
These toggle links are expanded or contracted by a screw spindle working
through a screwed nut secured to the joint of the pair of main levers, and the
plain part of the screwed spindle passing through a block secured on the joint
of the other levers where a shoulder is formed on it to form an abutment.

page_text: the same is to be performed to be particularly described and ascertained in and
by the following statement in writing, reference being made to the accompanying
drawings;-
This invention has reference to and comprises improvements in belts for the
cure or relief of spinal weakness, by which such belts are rendered more effica-
cious, and when used for growing young persons are capable of adjustment to
suit their growth, thus obviating the necessity of renewing the belts.
And in order that my said invention may be properly understood I have
hereunto appended one sheet of explanatory drawings, in which the same reference
letters are used to indicate the same or equivalent parts where shown.
According to my improvements as illustrated by Figure 1 of the drawings,
which is a view of one half or one side of a belt constructed in accordance with
my invention, the belt is made in two parts A, A¹ connected at each side by
toggle link joints B capable of being expanded and contracted by means of a
screw C.
One part A of the belt is formed to fit around the body, padded and recessed
at a to fit over the hips and be held in position there by straps D and buckles
or equivalent fastenings. The other part A' is formed to fit under the arm
pits in a similar manner.
These two parts A, A' are connected together at each side by toggle links B
formed by a pair of levers B1, B2 jointed together and pivotted or connected one
to each part A and A¹ of the belt, and connected by another pair of levers B³
jointed at their outer ends, and each lever B³ pivotted on one of the main
levers B, B. The main levers B1, B2 are preferably formed at the pivotted
end broad and finished of a semi-circular shape, and rest in corresponding
shaped metal lined sockets or recesses a¹ secured to the upper and lower parts A, A¹
of the belts and preferably also pivotted there.
These toggle links B are expanded or contracted by a screwed spindle C
working through a screwed nut Û secured to the joint of the pair of levers B³,
and the plain part of the screwed spindle C passes through a block secured on
the joint of the other levers B1, 132, where a shoulder c is formed on it to form
an abutment.
By another and equivalent arrangement, as illustrated by Figures 2 to 4,
instead of toggle links a pair of elongated plates or links are used sliding on one
another and adjusted in relative position by a screw. These metal links B1, B2,
are secured in the recesses a¹ where they may be rivetted or pivotted, and slide
one upon the other, being loosely rivetted together at ³, the rivet passing
through the slot 62 in the link BĬ.
The end of the screw C rests in a hole or centre in the bracket 1 secured on
the end of the link B2, and works in a block or nut C¹ secured to the link B¹,
its stem passing through a slot 4 in the link B2. A small wheel or disc C³ with
milled edge is secured on the screw C by which it is turned to expand or con-
tract the links B1, B2, so as to adjust the distance between the upper and lower
parts A, A, of the belt.
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:-
First. Belts for the cure or relief of spinal weakness constructed and arranged
substantially as herein described and illustrated by the accompanying drawings.
Second. Belts for the cure or relief of spinal weakness formed in two parts
connected together by toggle links or equivalent adjusting screw appliances
substantially as herein described and illustrated by the accompanying drawings.
Third, Belts for the cure or relief of spinal weakness formed in two parts
connected by adjustable toggle links actuated by a screwed spindle substantially
as herein described and illustrated by Figure 1 of the accompanying drawings.
Fourth. Belts for the cure or relief of spinal weakness formed in two parts

as herein described and illustrated by Figures 2 to 4 of the accompanying
drawings.
