Improvements in Springs,
I WILLIAM BOYES of 136 Barford Street Birmingham in the County of Warwick
Spring Maker, do hereby declare the nature of this invention to be as follows:-
For Railway Waggons, Vans, Carriages, Coaches, and every discription of
Springs.
First or top Steel Plate, to be rolled (to any given dimension) with a rib, on the
one side of the Plate, either square or taper, as shown in Drawing Fig. I.
Second or intermediate Plate to be rolled with a groove on the one and a rib on
the opposite side either square or taper, see Drawing Fig. II.
Third or bottom Plate, to be rolled with a groove only, as shown in Fig. III, these
Plates are made so as to fit into one another thus keeping them from moving sideways
and which will give more security and strength also fewer plates are required and
the weight meterialy reduced then in the ordinary way of making, with Stud
and Slot.
Where there are more Plates required then three, as discribed above, the second
Plate (as shown with groove and a rib see Fig. II) will take the place for as many
additional plates as required.

COMPLETE SPECIFICATION.
Improvements in Springs.
WILLIAM BOYES of 118 & 120 Barford Street Birmingham in the County of
Warwick, Spring 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 :—
For Railway Waggons, Vans, Carriages, Coaches and every description of
Springs.
First or top Plate to be rolled to any given dimension, with a rib on the one
or under side either square or taper as shewn and set forth in Drawing Fig. I,
accompanying the provisional Specification.
Second or intermediate Plate to be rolled with a groove on the top side, so that
the rib of the first or top Plate will fit into the same; on the bottom or opposite
side of this Plate, is rolled a rib (as described in first Plate) and shewn in Drawing
Fig. II.
Third or bottom Plate is rolled with a groove only on the one or top side, to
receive the rib of the second Plate, as shewn in Drawing Fig. III.
Where more then three Plates are required the second or intermediate Plate, (as
described & shewn in Drawing Fig. II) will take the place for as many additional
Plates as required.
These Plates are made so as to fit into one another thus keeping them from moving
or slipping sideways, give more security and strength, then in the ordinary way of
making Springs with Stud & Slot, also fewer Plates are required therefore the weight
is materially reduced.

page_text: Having now particulary described and ascertained the nature of my said Inven-
tion, and in what manner the same is, to be performed, I declare that what I
claim is:
Springs made with ribs and grooves either on top or bottom side of the Plates to
run the whole or part of the length i.e. the deepest of the ribs and grooves are in the
middle of the Plates and then run itself out towards the ends, in the same manner
as the Plates or Springs taper.
Dated this 26th day of December 1889.
WILLIAM BOYES.
