Improvements in Springs for Carriages and other Vehicles.
HARRY WALKER and Toм WALKER 125 Wellington Road, Leeds Yorkshire
Mechanical Engineers do hereby declare the nature of this invention to be as
follows:-
The object of our invention is to construct an elliptic or other spring without the
usual fixed head eye or cups, and having its bearings on some soft material, thus
rendering it noiseless in working, simpler in construction combined with an easy
adjustment for taking up the wear and rattle.
We construct the spring in the usual way with the exception of the head, when
in lieu of the fixed head, eyes or cups now used we use a loose head or cap made in
steel or metal and lined with rubber or other noiseless elastic material, with cover
to take in spring ends and lugs to keep plates from working sideways & protect
parts from dust &c. &c. In combination with head we use a bolt, round T head by
preferance which passes through a rubber tube and section of metal ferrule, the
combination of which form a fulcrum or centre upon which the ends of the spring
work. The construction is simplified by useing the loose head or cap in place of
the fixed one, it being only necessary to have the main plate ends bent to the
required radius instead of forging on the usual heads, eyes, or cups, and by having
the bearings arranged so that the bolt passes through them and out at the end
of spring to enable the wear and rattle to be taken out by the lock nut provided.
And in order that our invention may be more completely understood referance is
given to the accompanying drawings and to the letters and marks thereon.

page_text: we have described and shewn as the same may be varied or modified without in any
way departing from the nature of our said invention.

Improvements in Springs for Carriages and other Vehicles.
HARRY WALKER and Tом WALKER Engineers of 125 Wellington Road
Leeds in the County of York 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 :-
The object of our invention is to construct an elliptic or other spring without the
usual fixed head, eye or cups and having its bearings on some soft material, thus
rendering it noiseless in working, simpler in construction combined with an easy
adjustment for taking up the wear and rattle.
We construct the spring in the usual way with the exception of the head, when
in lieu of the fixed heads eyes or caps now used, we use a loose head or cap made
in steel or metal and lined with rubber or other noiseless elastic material, with cover
to take in spring ends and lugs to keep plates from working sideways and protect
parts from dust &c. In combination with head we use a bolt, round T head by
preferance which passes through a rubber tube and section of metal ferrule, the
combination of which form a fulcrum or centre upon which the ends of the
spring work.
The construction is simplified by using the loose head in place of the fixed one.
It being only necessary to have the main plate ends bent to the required radius
instead of forging on the usual heads, eyes or cups, and by having the bearings
arranged so that the bolt passes through them and out at end of spring to enable
the wear and rattle to be taken out by the lock nut provided.
And in order that our invention may be more completely understood referance is
given to the drawings and to the letters and marks thereon, left with the Provisional
Specification.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation of complete elliptic spring constructed in accordance
with our invention
Fig. 2 is plan of same,
Fig. 3 end view enlarged shewing clearance of spring ends,
Fig. 4 enlarged section of head constructed in accordance with our invention and
shewing arrangements of bearing parts,
Fig. 5 & 6 enlarged plan & sectional plan shewing bolt & nut.
The box or cap a can be stamped or made in any suitable metal, 6 lining of rubber
or other noiseless elastic material acting as a cushion to main or back plate c, d tube
put on section of metal ferrule e and bolt passed through so as to keep the whole
in position and form fulcrum or centre. It will readily be seen that the spring
plates do not come in contact with the metals but work on the rubber bearings d
and and that the wear and rattle can easily be taken up by means of the nut
which owing to its shape acts as a lock nut after being set. It being simpler in
construction owing to the head and wearing parts being loose from the main plates
and the worn parts and bearings are replaceable without having to take the spring
off the carriage.
Although we have shewn the nut of bolt on the outside of spring, where neatness
is a consideration as in brougham or composite springs the nut can be put inside and
the head let in flush with the shell of cap.

page_text: Having now described the nature of our said invention and shewn by the aid of
drawings how the same may be carried into practice we would have it understood
that we do not limit ourselves to the presise details or configurations of the parts
we have described and shewn as the same may be varied or modified without in any
way departing from the nature of our said invention, what we do claim is :-
Firstly. The arrangement, construction and application of the box or cap a at
end of spring with rubber, ferrule and bolt for attaching the top and bottom parts
of spring, or as in the case of single springs to the scroll or bearing part of carriage,
substantially as herein set forth.
Secondly. The arrangement and combination of the various parts forming our
improvements in springs for carriages and other vehicles and mere modifications of
same substantially as herein set forth.
