JAMES DAKERS of 24 Union Row and 7 Union Wynd Aberdeen North
Britain Coach Builder do hereby declare the nature of this invention to be as.
follows:-
This inventions relates to certain improvements in the construction of household
furniture and their fittings and is designed to render the same much more effective
and durable than anything that has hitherto been constructed.
The first part of my inventions is to strengthen the castors for chairs and other
furniture. This I propose doing by making a socket of brass, iron or glass with a
solid inside center. 1 form a solid pin or bearing on top end of inside center leaving
a groove round inside pin and inside of socket. I form a groove on bottom of
socket. I make a castor of brass, iron or glass. I form a round flat bearing on top
of horne, which fits into bottom groove of socket, forming a bearing all round
bottom of socket. I form a bracket off side of horne, which is carried upwards
forming a bearing against outside of top socket. I also make a ridge or groove
round top socket to bear against bracket. I make a wheel of brass, iron, or glass.
I make a groove round outside of wheel. I insert an indiarubber ring into groove.
I fit wheel into bracket, passing an axle through brackets and center of wheel. I
make an axle of iron or steel. I pass it through solid pin of socket and down
through horne of castor. I make a head on the one end or I may cast it into the
solid pin. I screw the other end and fit on washer and nut to hold on castor.
Secondly. I insert a spring into the leg of a chair or other furniture by boring
a hole to receive same. I put on socket. I make the axle which passes through
the solid pin of socket to bear against the end of spring, the axle to act as a buffer
or I may form a double socket round the inside of top socket to receive the spring
the axle passing up through the center.
Thirdly. I form a socket with a solid division inside which forms a double socket,
the one end is to receive leg of a chair or any other piece of furniture. I make a
screw round the inside of bottom end. I fill socket with an indiarubber buffer.
Fourthly. I cut the back of a chair above seat frame. I put on two hinges. I
make a spiril spring of steel. I inclose it into two brass tubes, the one tube to
slide into the other to let the spring work. I form a bead or check on the smaller
tube to check the movement of spring. I form a joint at the one end of socket,
and a pin at the other. I screw the joint end to the bottom frame of chair, and
the other end I fasten to the center rail of back the spring standing upright, the
spring keeping the back of chair in position.

Improvements in and relating to Chairs and other Articles of
Furniture.
JAMES DAKERS of 24 Union Row and 7 Union Wynd Aberdeen North
Britain Coach Builder 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 :-
This invention relates to certain improvements in the construction of household

page_text: furniture and their fittings, and is designed to render the same, much more effective
and durable than anything that has hitherto been constructed.
The first part of my inventions is to strengthen the castors for chairs and other
furniture. This I propose doing by making a socket of brass iron or glass, with a
solid inside center. I form a solid pin or bearing on top end of inside center
leaving a groove round inside pin and inside of socket. I form a groove on bottom
of socket. I make a castor of brass iron or glass. I form a round flat bearing
on top of horne, which fits into bottom groove of socket forming a bearing all
round bottom of socket. I form a bracket off side of horne, which is carried
upwards, forming a bearing against outside of top socket. I also make a ridge
or groove round top socket, to bear against bracket. I make a wheel of brass
iron, or glass. I make a groove round outside of wheel. I insert an india-
rubber ring into groove. I fit wheel into bracket, passing an axle through brackets
and center of wheel. I make an axle of iron or steel. I pass it through solid pin
of socket, and down through horne of castor. I make a head on the one end, or I
may cast it into the solid pin. I screw the other end, and fit on wasber and nut
to hold on castor.
Secondly. I insert a spring into the leg of a chair or other furniture, by boring
a hole to receive same. I put on socket. I make the axle which passes through
the solid pin of socket to bear against the end of spring the axle to act as a buffer
or, I may form a double socket round the inside of top socket to receive the spring
the axle passing up through the center.
Thirdly. I form a socket with a solid division inside which forms a double socket,
the one end is to receive leg of a chair, or any other piece of furniture. I make a
screw round the inside of bottom end. I fill socket with an india-rubber buffer.
Fourthly. I cut the back of a chair above seat frame. I put on two hinges. I
make a spiril spring of steel. I inclose it into two brass tubes, the one tube to
slide into the other to let the spring work. I form a bead or check on the smaller
tube to check the movement of spring. I form a joint at the one end of socket,
and a pin at the other. I screw the joint end to the bottom frame of chair and the
other end I fasten to the center rail of back, the spring standing upright the spring
keeping the back of chair in position.
And in order that my invention may be more completely understood, reference
is given to the accompanying sheet of drawings and to the letters and marks
thereon.
Fig. I represents castor and the several parts connected therewith put together
in position according to my invention for strength.
Fig. II shows castor separately.
Fig. III. The second part of my invention shows parts put together in position
with spiril springs to relieve dead shocks.
Fig. IIII shows castor separately.
Fig. V. The third part of my invention shows socket and rubber buffer to give
ease and strength.
Fig. VI. The fourth part shows spring on back of chair which yields when
pressed against.
Details to be described hereafter.
Firstly. I make a socket A of brass or other sutiable metals with a solid center X.
I form a solid pin B or bearing on top of center X leaving groove C. I form a
groove E on bottom. I make a castor H of brass or other metals. I form a flat
bearing E on top of horne F which is shown separately at Fig. 2. fitting into
socket A and bearing D. I form bracket H which bears against K and A. I
make a wheel J. I cut a groove round outside of wheel. I insert an india-rubber
ring I into groove. I fit wheel J into bracket H. I make an axle O. I pass it
through solid pin B and down through horne F. I make the head N on the top
end. I screw the other end and fit on washer and nut W.
In the second part of my invention Fig. 3. and 4. I insert the spring P into the
leg of chair M. I put on socket A. I make the axle O which passes through

page_text: solid pin B. Y to bear against spring P or I may form a double socket A. A to
receive the spring P. the axle O passing up through the center.
Thirdly. Fig. shows socket A with solid division X. The one end is to
receive leg of chair M. I form a screw R. R. I insert an india-rubber buffer I.
Fourthly. Fig. 6 shows the back of a chair Q which is hinged at SS. I fasten
on two hinges to allow the back to move. I make a spiril spring P of steel. I
inclose the spring P into two brass tubes YY one of the tubes smaller than
the other to allow spring to move. I form the bead or check L on the smaller
tube to regulate the movement of spring P. I make a rod or pin A. I form
a hinge N on the one end of rod A which is screwed to the bottom frame Z.
I make a shield plate which is screwed on the back. U. Pin A passes through
centre of sockets Y Y spring P and shield plate the back of chair yielding
when pressed against.
Having now described the nature of my said invention and shown by drawings
how the same may be carried into practice I would have it understood that I
do not limit myself to the exact limits details or configuration of the parts I
have explained and shown as the same may of course be varied or modified without
in any way departing from my invention but what I do claim and desire to be
secured to me by Letters Patent is.
Firstly. The improved arrangement construction and combination of the parts
of castors and their fittings substantially in the manner and for the purpose herein-
before described with reference to Figures 1. 2. 3. 4.
Fig. I socket A and solid center X and solid piu B bearing D and K and
axle O.
Fig. 2 bearing E E and bracket H.
Secondly. Fig. 3 and 4 spiril springs P and sockets A A.
Thirdly. Fig. 5 solid socket A A center X screw R rubber buffer I.
Fourthly. Fig. 6 spiril spring P and sockets Y Y and pin A hinge N check L.
