I ALFRED LENZ of 9, Maxergasse Vienna in the Empire of Austria Civil
Engineer do hereby declare the nature of this Invention (being a communication
from abroad by Franz Kamper of Vienna in the Empire of Austria Governmental
Inspector of Railways) to be as follows:-
This invention relates to a method of constructing laminated springs from or
composed of any required number of steel plates each formed with one or more
corrugations parallel to the length of the plate such plates being put together and
arranged in pairs with corresponding depressions of surface on opposite sides of a
centre line between the two plates thereby admitting of the elevations of surface
therein being in contact or nearly in contact so as to bear against and support one
another.
In the said arrangement of a pair of corrugated plates such plates are not
arranged so that the convexity or elevation of surface in the corrugation of one
plate may be caused to fit into the corresponding concavity or depression of surface
in the corrugation of the other plate but with the convexities in contact or nearly
BO. And in combining the several pairs of plates so as to form a spring such pairs
of plates are likewise similarly arranged respectively so as to afford mutual support
to one another.
The corrugations may be made to extend throughout the entire length of the
plate or only through a portion of the length as may be required. Also the
depth of the corrugation may be made to vary from the middle towards the ends
of the plate.
In order to prevent lateral motion between any two plates or pairs of plates short
lengths of bars may be inserted which fit into and more or less fill up some of the
spaces between the corrugations.
Such bars may be used either with or without slots and studs or slots and studs
may be used alone. The plates may also be fastened together in any other suitable
manner.

I ALFRED LENZ of 9 Maxergasse Vienna in the Empire of Austria Civil
Engineer do hereby declare the nature of this invention (being a communication
from abroad by Franz Kamper of Vienna in the Empire of Austria Governmental
Inspector of Railways) 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 .a method of constructing laminated springs from or
composed of any required number of steel plates each formed with one or more
corrugations parallel to the length of the plate such plates being put together and
arranged in pairs with corresponding depressions of surface on opposite sides of a
centre line between the two plates thereby admitting of the elevations of surface
.therein being in contact or nearly in contact so as to bear against and support one
another.
In the said arrangement of a pair of corrugated plates such plates are not
arranged so that the convexity or elevation of surface in the corrugation of one
plate may be caused to fit into the corresponding concavity or depression of surface
in the corrugation of the other plate but with the convexities in contact or nearly
BO. And in combining the several pairs of plates so as to form a spring such pairs
of plates are likewise similarly arranged respectively so as to afford mutual support
to one another.
The corrugations may be made to extend throughout the entire length of the
plate or only through a portion of the length as may be required. Also the
depth of the corrugation may be made to vary from the middle towards the ends
of the plate.
In order to prevent lateral motion between any two plates or pairs of plates short
lengths of bars may be inserted which fit into and more or less fill up some of the
spaces between the corrugations.
Such bars may be used either with or without slots and studs or slots and studs
may be used alone. The plates may also be fastened together in any other suitable
manner.
In order that my invention may be fully understood I will describe it more
particularly by reference to the accompanying drawings in which Fig. 1 is a croas
section of a single plate (full size) corrugated in such a manner as to adapt it in
combination with another correspondingly corrugated plate or plates to form or
constitute a laminated spring of the kind required.
Fig. 2 is a similar section showing two plates put together and fastened so
as to be capable of affording mutual support to one another in the manner above
stated.
And Fig. 8 ista similar section of a spring with four plates arranged in pairs,
and with the convexities in contact or nearly so in order that the plates may afford
mutual support to one another.

page_text: Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, (communicated to me
from abroad as aforesaid) I would remark that I am aware of laminated springs
having been constructed with corrugated plates with the corrugations fitting into
one another which I mention in order to state that I do not claim springs so
constructed. But I declare that what I claim is:
The construction of laminated springs composed of plates corrugated so that the
plates when put together and suitably fastened shall have the convexities of their
corrugations brought in contact or nearly so and thereby afford mutual support to
one another in the manner substantially as described.
