Improvements in Chain Pumps.
THOMAS EDDLESTON, 2, Higher Bank Street, Blackburn, Commercial Traveller,
and JOHN JAMES WINTERBOTTOM, 4, Richmond Terrace, Blackburn, Commission
Agent, do hereby declare the nature of this invention to be as follows: -
This invention relates to the chains and discs of pumps. We place rubber or
similar material on the chain or disc to fit inside the pipe, which prevents the
liquid from flowing back into the tank so quickly as in the case of pumps now in
use.

Improvements in Chain Pumps.
We, THOMAS EDDLESTON, of 2, Higher Bank Street, Blackburn, in the County
of Lancaster, Commission Agent, and JOIN JAMES WINTERBOTTOM, of 4, Richmond
Terrace, Blackburn aforesaid, Moss Litter Agent, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:—
This invention relates to improvements in the chains and in chain pumps for
raising liquids, the object being to increase the capabilities of such pumps by
preventing the column of liquid when once raised into the barrel of the pump
from returning or falling through the force of gravitation, and this even though
the chain of the pump is stationary. The invention consists in combining with a
number of the discs of the chain a disc or ring of rubber or other elastic sub-
stance which fills the interior of the barrel of the pump.
Such being the nature and object of our said invention the following is a com-
plete description of same reference being had to the accompanying drawings in
which
Fig. 1 is a view in elevation of part of a chain of a chain pump with our im-
provements applied thereto.
Fig. 2 is a sectional elevation of part of the barrel of a chain pump shewing
a portion of the chain with our improvements applied thereto.
According to this invention the pump and chain are made in the ordinary
manner, but in each chain 1 there are 3 or more rings or discs 2 of rubber or
other elastic substance placed at equal distances apart on the said chain 1. The
Price 8d

page_text: links 3 of the chain 1 which are to carry the rubber rings or discs 2 are provided
with 2 flanges or discs 4 of metal fixed thereon and between these flanges the
rubber ring 2 is sprung and by them held as shewn by Fig.1.
When in operation the rubber rings or discs 2 fill the interior of the barrel 5
of the pump (see Fig. 2) and liquid once raised into the barrel of the pump will
not readily fall even when the pump is stationary and better practical results are
obtained and a greater quantity of liquid raised with less expenditure of power.
In practice we have found that in a pump the barrel of which is about 12 feet
high 3 discs or rings 2 spaced at equal distances apart on the chain give good
results and in this case there will always be one of the discs 2 inside the barrel.
In barrels of greater length 2 or more discs or rings 2 may be inside at the same
time.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
The use in combination with the chain of a chain pump of rubber discs or rings
as and for the purpose herein described and substantially as illustrated by the
annexed drawings.
