I, JAMES ALFRED TURNER of Nutsford Vale West Gorton near Manchester
Manufacturer do hereby declare the nature of the said invention for "AN IMPROVED
CONSTRUCTION OF SPRINGS FOR EASING THE LATERAL MOTION OF CARRIAGE WHEELS
UPON THEIR AXLES AND FOR OTHER PURPOSES to bo as follows:-
#
My invention has for its object the construction of an annular spring acting
under compression, which shall give an effective bearing at four or more points and
shall be more uniform and easy in its action than ordinary helical springs, or
corrugated spring washers. For this purpose I attach to diametrically opposito
points of an annular plate or washer two horn shaped springs, secured at their
middle to the plate and curving up from the same with their two ends. There
are two such plates with horn shaped springs, and they are placed together so that
the ends of the one set of springs bear upon the middles of the other sot, a certain
distance being made to intervene between the contiguous cuds of each set of springs,
so as to leave room between them for a projection fixed or formned on the middle of
the other set; such projection is made to fit with a certain amount of play between
the ends of the springs so that when pressuro is applied to the combined springs
tending to flatten them down, sufficient room is left between their ends and the said
projections to allow them to do so. The said projections enable the two sets of
springs to be readily fitted together and retained in the correct position relatively
to each other. The horn shaped springs have a double or helical curvature and
their ends are formed so as to bear with their entire width against the opposite
springs, so as to reduce wear as much as possible.
These springs are more particularly applicable for casing the lateral notion of
carriage wheels upon their axles for which purpose they are fitted upon the axle at
one or both ends of the axle box. They are however equally applicable in all cases
where annular or helical springs or spring washers are used. When a greater
amount of elasticity is required than can be afforded by a single pair of such
springs, two or more pairs may be placed upon or against each other. Or an annular
plate having a pair of the said horn shaped springs fixed on cach side thereof is
combined with two plates having each a pair of springs fixed on one side thereof.
When the springs require to be of large diameter, there may be three or more
such horn shaped springs provided round the annular plate, instead of only two.

Manufacturer, do hereby declare the nature of my invention for "AN IMPROVED
CONSTRUCTION OF SPRINGS FOR EASING THE LATERAL MOTION OF CARRIAGE WHEELS
UPON THEIR AXLES AND FOR OTHER PURPOSES" and in what manner the same is
to be performed to be particularly described and ascertained in and by the
following statement :——
My invention has for its object the construction of an annular spring acting
under compression, which shall give an effective bearing at four or more points
and shall be more uniform and easy in its action than ordinary helical springs, or
corrugated spring washers. For this purpose, I attach to diametrically opposito
points of an annular plate or washer two horn-shaped springs, secured at their
middle to the plate and curving up from the same with their two ends. There are
two such plates with horn shaped springs, and they are placed together so that the
ends of the one set of springs bear upon the middles of the other set, a certain
distance being made to intervone between the contiguous ends of each set of
springs so as to leave room between them for a projection fixed or formed on the
middle of the other set; such projection is made to fit with a certain amount of
play between the ends of the springs, so that when pressure is applied to the
combined springs, tending to flatten them down, sufficient room is left between their
ends and the said projections to allow them to do so. The said projections enable
the two sets of springs to be readily fitted together and retained in the correct
position relatively to each other. Tho horn shaped springs have a double or helical
curvature and their ends are formed so as to bear with their entire width against
the opposite springs so as to reduce wear as much as possible.
These springs are more particularly applicable for easing the lateral motion of
carriage wheels upon their axles, for which purpose they are fitted upon the axle at
one or both ends of the axle-box. They are however equally applicable in all
cases where annular or helical springs or spring washers are used. When a greater
amount of elasticity is required than can be afforded by a single pair of such
springs, two or more pairs may be placed upon or against oach other. Or an annular
plate having a pair of the said horn shaped springs fixed on each side thereof is
combined with two plates having each a pair of springs fixed on one side thereof.
When the springs require to be of large diameter there may be three or more
such horn shaped springs provided round the annular plate, instead of only two.
Fig. 1 of the accompanying drawings shews a perspective view of one arrangement
of the before described springs and fig. 2 shows a side view of two of them fitted
together. A is the annular flat plate to which the two horn shaped springs B B
are secured at their middles C O," while their two ends are bent up with a double
curvature on either side and terminate with straight edges which are a sufficient
distance apart to admit the projections O¹ C¹ of the opposite spring between them
when the two springs are fitted together as at fig. 2. Thus it will be seen that the
straight edges of the ends of the springs B B, owing to their double curvature, are
made to take a flat bearing on the middles of the springs B¹ B3', on each side of
the projection C, while the ends of the springs B' B¹ in like manner take a bearing
against the middles of the springs B B, thus giving four points of support for the
combined springs.
As before stated, sufficient play is allowed between the ends of the springs and
the sides of the projections to allow of the springs being flattened down more or

page_text: less when pressure is applied. D D' are leather washers which are by preference
applied between the liscs A A' and the shoulders of the carriage axle and
axle box.
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 :-
1. The herein described construction of spring consisting of an annular disc A to
which are secured two or more horn shaped springs B so formed with a double
curvature and straight edges as to take a flat bearing against a second similar
spring.
2. The combination of two springs such as are referred to in the preceding claim
arranged and operating as herein described with reference to fig. 2 of the drawings,
