SAMUEL SEALY ALLIN Woodstock Road Bedford Park County of Middlesex
Gentleman, do hereby declare the nature of this invention to be as follows:-
This Invention relates to further improvements in Letters Patent granted to me on
the 9th day of October 1885 No. 11994 and is designed for the purpose of causing
the floats to feather mechanically and without motion relative to the links to which
they are connected and also for the purpose of effectually supporting the floats and of
relieving the links of the chains from the ill effects of jar and vibration from which
they suffer, if the floats are directly connected to them.
In carrying out these improvements I cause the pins passing through the eyes of
the links to project inwards through such links sufficiently far to support brackets
opposite each other. These brackets are provided with suitable holes for the entrance
of the link pins so that when they are in their place they are supported in positions
paralel to the links. The lower extremity of each bracket terminates in a foot or plate
a little distance below the bottom eye of its link and braces of suitable section, as
bulb, T, or channel iron extend from the bracket on one chain to that on the other,
bolted fimly to both, the whole, that is the pair of brackets and the braces forming a
rigid cradle which carries the float.

I, SAMUEL SEALY ALLIN of Woodstock Road, Bedford Park in the county of
Middlesex Gentleman 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:-
This invention relates to further improvements in Letters Patent granted to me on
the 9th day of October 1885, No. 11,994 and is designed for the purpose of causing
the floats to feather mechanically and without motion relatively to the links to which
they are connected, and also for the purpose of effectually supporting the floats, and
of relieving the links of the chains from the ill effects of jar and vibration from which
they suffer, if the floats are directly connected to them.
In carrying out these improvements, I cause the pins passing through the eyes of
the links to project inwards through such links, sufficiently far to support brackets
opposite each other. These brackets are provided with suitable holes for the entrance
of the link pins, so that when they are in their place they are supported in positions
parallel to the links. The lower extremity of each bracket terminates in a foot or
plate at the forward end of its link, or preferably (except with very heavy floats) in
advance thereof, and braces of suitable section, as bulb, T, or channel iron, extend
from the bracket on one chain to that on the other, and are secured firmly to both,
the whole, that is the pair of brackets and the braces, forming a rigid cradlo which
carries the float. In some cases in the smaller motors, to cheapen cost of construction
the cradles might consist each of a pair of links of the chains with projections to
which braces extending from one to the other would be secured, by this arrangement
the advantage of a rigid float giving a direct downward pull on the chains would be
obtained, although the chain links would not escape direct communication of vibration
as with the cradles entirely separate as before described.
In the accompanying two shoots of drawings the manner in which I effect my
objects is clearly shewn.
Fig. 1 is a section of a float and cradle showing how they are put together, Fig. 2
is a front view of cradle and float and chain links showing structure of the whole and
attachment of float to the chains. Fig. 3 is a plan view shewing tiansverse braces of
angle iron, which I employ to stiffen wide floats, Fig. 4 is a modified form of bracket.
Fig. 5 is a diagram showing the feathering produced by the mode in which the floats
are attached to the chains.
Similar letters refer to corresponding parts in all the figures.
In Fig. 1. A is the bracket with two holes a a to go on to the overlengta of chain
pins shown at a¹' a' in Figure 2. B B are the bulb irons, which, with the two brackets
form the cradle and support the float, so that it shall not bend under the weight of
water and draw the chains inwards, and C is the float which I have shewn secured
between the bracket and the bulb irons. The relative positions of these parts may be
varied, one or both bulb irons for instance being on top of the float; the object of

page_text: one of
the construction being to produce a rigid structure, which when loaded shall exert a
straight downward pull on the chains. In Fig. 2 A, A, are the brackets,
the bulb irons, C the float, D D the transverse angle iron braces, E E the chain links,
and a a¹ the pins of the chains, on which, and not directly on the links, the cradle
and float are carried. In Fig. 3, C is the float, D, D, the transverse braces, F F strips
rivetted on to strengthen the edges of the float. Fig. 4 shews an alternative form of
bracket A carried only on one pin, but having a bar S reaching from one end to the
pin above, which answers the same purpose as the larger bracket in Fig. 1. Fig. 5
shows the effect of the mode of attaching the floats, on their position when passing
round the bottom guide pulleys H, and the degree of feathering obtained.
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.
(1) In a chain water motor, obtaining feathering without any swivelling or swinging
motion of the floats relatively to the links, by placing in advance, or at the forward
end of the pair of links to which they are connected, substantially in the manner
described.
(2) In a chain water motor carrying the floats in rigid cradles, substantially as
described.
(3) In a chain water motor the mode of freeing the chains from the injurious
action of vibration by carrying the floats, not on the chain links, but on the over-
lengths of the pins, substantially as described.
