I WILLIAM PETTINGER WEST WEATHERILL of 33 Beech Street Hightown in the
City of Manchester in the County of Lancaster Coach Body Maker do hereby declare
the nature of this invention to be as follows:-
I sometimes make the backs or main plates of Elliptic springs in one endless piece
and make it the required shape in lieu of connecting the top and bottom parts at the
end or ends with a bolt or bolts.
Sometimes I take two pieces of spring steel plate the required length and weld
them together at the end or ends so that the top and bottom parts will press
together.
Sometimes I may jump or turn over the end or ends of the plate or plates to form
a thicker end or ends or I may weld a piece of iron or steel on the end or ends of the
plate or plates so as to make the ends of the spring correspond with the present shape
of springs.
may
.I sometimes take a piece of steel long enough to double over to form top and
bottom half or halves of springs. I may weld one or both ends as required or
take a piece of spring steel long enough to turn over at both ends close enough for
bottom and top part to touch and weld the end or ends of the plate or plates together
in a suitable part. Having welded the backs or main plates so as to make them into
one endless piece I sometimes use them so as a complete spring or I may add one or
more plates to top and bottom parts to stiffen them.
In some cases 1 lighten the end of the backs or main plates at or towards the end
or ends leaving the centres thicker.

page_text: COMPLETE SPECIFICATION.
Improvements in and Applicable to the Springs of Vehicles.
I WILLIAM PETTINGER WEST WEATHERILL of 33 Beech Street Hightown in the
City of Manchester in the County of Lancaster Coach Body Maker 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 and accom-
panying drawings :—
My invention relates to the formation of the backs or main plates of Elliptic Springs
for vehicles and the welding together of such backs or main plates at their ends in
lieu of using bolts.
My invention will be most fully understood when described with reference to tho
drawings which accompany this specification.
In figures 1, 2 and 3, not drawn to any scale is shewn the form of the spring and
shape of back or main plates and how same are tapered and welded together.
Figure 1 shews two pieces of spring steel thined down in a tapered form towards
their ends, to cause the spring to work easy. The plates are shaped and the ends
welded together and may be used as shewn or the ends may be rounded by turning
them up or down.
Figure 1 also shews how the spring may be made stronger if required by the
addition of one or more plates to the top and bottom back or main plates.
Figure 2 shews how a piece of steel or iron may be welded on the inner sides of or
between the backs or main plates to form thicker ends.
Figure 3 shews at letter "A" how a piece of steel or iron may be welded to the
spring ends to give a shape to the spring end similar to a spring end when bolts
are used.
Figure 3 also shews at letter "B" how the ends of the backs or main plates may
be turned or rolled up and then welded to form thicker ends.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The combination of back or main plates tapered and welded together at the ends to
form Elliptic Springs (in lieu of connecting the top and bottom halves of springs
with bolts) in the manner substantially set forth and indicated hereinbefore and by
the accompanying drawings.
Dated this Nineteenth day of March 1888.
