PROVISIONAL SPECIFICATION
Improvements in Suspension Springs.
I, ROBERT CUTHBERT of 3 Cobden Terrace Eastfield Road Peterborough Coach
Trimmer do hereby declare the nature of this invention to be as follows:-
The object of my invention is to manufacture suspension springs of indiarubber or
other like substances, for use on bath chairs, carriages and the like, where immunity
from vibration is desirable.
I construct my springs or suspenders (of any size length and thickness) of solid
india rubber or other suitable material. Each end of the spring or suspender is
enlarged and pierced with a hole at right angles to its length.
This hole may be protected from wear by means of a lining of suitable bard
substance. The springs or suspenders are attached to the body and framework of tho
vehicle by means of bolts screws or pins passed through the before mentioned holes
or by other suitable methods.
Any number of my suspension springs may be used according to the weight to be
supported or the flexibility required.
They may also be used for the suspension of seats, lounges and bedsteads or other
articles and can be affixed to any existing form of carriage or the like.
By the use of my invention the suspended body or seat is kept free from jolting, the
vibration from the framework being absorbed by the india rubber suspenders.
Dated this 6th day of September 1890.

Improvements in Suspension Springs.
I, ROBERT CUTHBERT of 3 Cobden Terrace Eastfield Road Peterborough Coach
Trimmer 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 :-
The object of my invention is to manufacture suspension springs of india rubber or
other like flexible substances, for use on all descriptions of bath chairs, carriages,
bassinettes and other like vehicles where immunity from vibration is desirable.
With this object I manufacture my suspension springs of solid india rubber, or
other suitable and flexible material, of any size, length and thickness required in
proportion to the weight to be carried or supported. Each end of the spring or
suspender, is enlarged and pierced with a hole of any suitable dimensions, at right
angles to the length of the spring. This hole should be protected from wear
preferably by means of a lining of metal or other hard or wear resisting substance.
The springs or suspenders are attached in any convenient positions to the body and
framework or under carriage of the vehicle by bolts, screws, pins or any other suitable
method or means, and any number of springs or suspenders may be used, as found
most convenient, in proportion to the weight to be supported, and the flexibility
required. The springs or suspenders may be used for the suspension of lounges,
bedsteads or any other articles where immunity from vibration is desirable and can be
affixed to existing forms of carriages and the like.

wear.
Fig. 3. shows an elevation of a bassinette, the body of which is suspended by the
rubber springs D, D, attached in the manner described to the body E by the lugs or
hooks F, F, and to the frame or under carriage EI, E at I, I.
By the use of my invention any body or seat suspended by my springs, is kept
very free from jolting and vibration from the main frame or under carriage, the
vibration being absorbed by the rubbor springs or suspenders, no part of the body or
seat being in metallic communication with the frame.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. The use of rubber suspension springs for the provention of vibration in vehiclos
generally.
2. The construction of such rubber springs or suspenders in the form herein fully
described, set forth and illustrated.
