I JOHN ROBERTSON of No. 412 Saint Vincent Street, Glasgow, Coach Builder, do
hereby declare the nature of this invention to be as follows :-
My invention has for its object in connection with wheeled vehicles, the combination
of a Cee spring with an elliptic spring, which is effected by securing the former to
the top of the latter.
Said combined Cee and elliptic springs may be applied to either the front or rear,
or to both ends of a vehicle. They may be fitted with or without perch, and with or
without braces over back, as also with or without racket.
Springs formed in accordance with my invention whilst ensuring the horizontal
position of the axles, have all the direct vertical motion of the elliptic combined with
the wave motion and elegant appearance of the Cee spring which easy motion may
also if desired be further enhanced by the addition of cross springs to the front or
rear, or to both ends of the vehicle.

page_text: A Combination Cee and Elliptic Spring for Wheeled Vehicles.
I JOHN ROBERTSON of No. 412 Saint Vincent Street, Glasgow, Coach Builder, 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 :-
My Invention has reference to a combined Cee and Elliptic Spring for carriages
and other vehicles; and is designed for the purpose of affording to the body of the
carriage or other wheeled vehicle the direct vertical motion of the elliptical spring
combined with the easy wave motion of the Cee spring, the whole forming an elegant
equipment for a wheeled vehicle.
In order that my Invention may be the better understood, I have appended the
accompanying sheet of drawings in which the hub of the outer wheel is shown at A,
the elliptic spring at B, and the Cee spring at C.
In carrying out my Invention I attach the elliptic spring B to the axle tree according
to the usual method, and brace upon it at H the laminated Cee spring C, which bears
the weight of the carriage body by means of the leather strap E coupled to the solid
link rod D, which latter supports the vehicle body G. I may or may not use a perch,
across the link rods D, and I may further enhance the delicacy of the suspension of
the body of the vehicle by the employment of cross springs-I may under some
circumstances use braces or cross ties, and similarly I may dispense with a racket.
The application of the combination spring according to my Invention-not only
improve the movement of the vehicle to which it may be adapted, but it also tends to
prevent the possibility of the axle turning or twisting from its rectilinear position.
Having now particularly 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 :
The improved combined Cee and elliptic spring for wheeled vehicles substantially
as herein described and shewn in the accompanying drawings.
Dated this Seventeenth day of November 1887.
