page_text: This Print is in accordance with the Original Specification as it stands after
Amendment (under Section 11 of the Patents, &c., Act, 1883), as required by
the decision of the Comptroller General of the 15th day of February 1897.
Improvements in the Construction of Rocking Chairs.
I, ALEXANDER PLANT of H. & A. G. Alexander and Company Limited of
Eastfield, Rutherglen, in the County of Lanark, Manufacturer, do hereby declare
the nature of my invention to be as follows:-
This invention has reference to and comprises improvements in the construction
of rocking chairs of the class which are constructed with a stationary baso frame
and a frame rocking thereon and connected to the base frame by helical or
equivalent springs and has for its object to change the rocking chair to a rigid
chair and vice versa at the will of the user.
The improvements of this invention under one modification consists in fitting to
the stationary base frame short bars or levers oscillating by one end on pivots
which may be screw nails or studs secured on the base frame and having their
other ends formed as hooks or clutches to engage with a transverse rail of the
rocking frame. These two bars or levers being connected by a transverse bar to
cause them to work in unison. When it is desired to make the chair a rigid one,
these bars would be oscillated upwards until the clutch parts engaged with the
transverse bar of rocking frame and hold said frame rigid to prevent it from
rocking.
The bars or levers would preferably be made of wood but they may be made of
iron or other suitable metal, and instead of using two, one at each side as described,
only one may be used mounted and oscillating on or along with a transverse bar on
the base frame.
They may also be mounted on the rocking frame and engage with the transverse
bar of base frame or though preferably fitted at the back of the chair they may be
fitted at the front.
By another modification one or more metal hooks may be fitted on either the base
or the rocking frame and be made to engage with eyes on the other frame.

Improvements in the Construction of Rocking Chairs.
1, ALEXANDER PLANT, of H. and A. G. Alexander and Company, Limited,
of Eastfield, Rutherglen, in the County of Lanark, Manufacturer, 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, that is to say :-
This invention has reference to and comprises improvements in the construction
of rocking chairs of the class which are constructed with a stationary base frame
and a frame rocking thereon, and connected to the base frame by helical or
equivalent springs, and has for its object to change the rocking chair to a rigid
chair and vice versa at the will of the user.
And in order that my invention may be properly understood I have hereunto
appended a sheet of explanatory drawings, in which Figure 1 is a side elevation
partly in section, and Figure 2 a back view of a rocking chair fitted with one
modification of my improvements.
The improvements of this invention under the modification as shown, consist in
fitting to the stationary base frame A short bars or levers B oscillating by one end
on pivots b which may be screw nails or studs secured on the base frame A, and
having their other ends formed as hooks or clutches B1 to engage with a transverse
rail of the rocking frame D. These two bars or levers B being connected by a
transverse bar B2 to cause them to work in unison. When it is desired to make
the chair a rigid one, these bars B would be oscillated upwards until the clutch
parts B1 engage with the transverse bar C of rocking frame D, and hold said
frame rigid to prevent it from rocking.
The bars or levers B would preferably be made of wood, but they may be made
of iron or other suitable metal, and instead of using two one at each side as
described only one may be used mounted and oscillated on or along with a transverse
bar on the base frame A.
They may also be mounted on the rocking frame D and engage with th
transverse bar A 1 of base frame A or though preferably fitted at the back of th.
chair, they may be fitted at the front.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I am aware of the specification
of Brown's application for a Patent No. 15871 of 1895 and I wish it to be understood
that I do not clain anything which has been patented on such application I declare
that what I claim is :-
First. The fitting of rocking chairs of the class described with moveable clutches
all substantially as and for the purposes herein described and illustrated by the
accompanying drawings.
Second. In rocking chairs of the class described the fitting of moveable clutches
or links between the rocking frame and lower base frame all substantially as set
forth.
