Engineers, and WILLIAM ROBERT GARDEN HAY, of Garford Street Engineering
Works, Garford Street, Poplar, in the County of Middlesex, Director and Manager
of the said Company do hereby declare the nature of this invention to be as
follows:-
This invention relates to Steering apparatus for ships and especially to that
description of such apparatus as is adapted to be operated by steam power and by
hand.
In order to obviate the ill effects of the impact of heavy seas on the rudder and
the conveyance of the shock to the operating parts, we employ a tiller and a
quadrant the one loose on the rudder head and the other affixed thereto, the one
being operated by the steam or hand power and operating the other. These two
members are connected so as to enable them to convey the operative motion from
one to the other and. thereby, to the helm by spring atachments.
The spring attachments consist of a box or trough, with a central and end or
other suitable stops or abutments. This box holds, say, two springs, such as coiled
steel of suitable cross section and dimension, each spring acts in compression, and
by means of a suitably constructed slider these springs are caused in the motion
of the slider carrying and retaining them to be compressed.
The slider is constructed on its side opposite to the springs with a part or parts
against which the tiller to be operated acts and the box is formed, with and so.
as in fact to become a part of the quadrant.
The connection of this slider and the tiller may be by-joggles in which the
tiller slides.
According to a modification the tiller may be connected to the slider by links
or such like connections from lugs or equivalent parts.

Improvements in Steering Apparatus.

This invention relates to steering apparatus for ships and especially to that
description of such apparatus as is adapted to be operated by steam power and by
hand.
In order to obviate the ill effects of the impact of heavy seas on the rudder and
the conveyance of the shock to the operating parts, we employ a tiller and a
quadrant the quadrant loose on the rudder head and the tiller affixed thereto,
the quadrant being operated by the steam or hand power and operating the tiller.
These two members the quadrant and the tiller are so connected as to enable
them to convey the operative motion from one to the other and thereby to the
helm by spring attachments.
DESCRIPTION OF THE DRAWINGS..
Fig. 1 is a plan view of a sufficient portion of the improved steering apparatus
as will illustrate our invention.
Fig. 2 is a sectional view taken on the line - Fig. 1.
Fig. 3 is an underside view of a portion of the apparatus shown in Fig. 1.
Fig. 4 is a sectional view taken on the line y-y Fig. 1, partly in elevation.
Fig. 5 is a detail sectional view taken on the line z-z Fig. 1.
Fig. 6 is a detail to be referred to.
Figs. 7 and 8 are part sectional views of the apparatus actuated to the right
hand and to the left hand respectively.
Figs. 9 and 10 show a modification by side view and end view respectively..
Fig. 11 shows a detail, being the part of the slide d...
The spring attachments consist of a box or trough a, with a central stop b and
end or other suitable stops or abutments 61, 62: This box a holds, say, two
springs c, c, such as coilea steel of suitable cross-section and dimension. Each
spring acts in compression, and by means of a suitably. constructed slider these
springs are compressed, the motion of the slider compressing both springs at the
same time.
The slider d is provided with parts d, d, against which the tiller e to be
operated acts. The box a is formed with and so as to become a part of the
quadrant f.
The connection of the slider d and the tiller e may be by joggles in which the tiller
slides.
The tiller e is keyed, or otherwise secured, to the rudder head g, whilst the
quadrant fis loose on the same.
Suitable stop plates h are provided in the box a which serve as abutments
against the stops b, b1, b. The part of the slider d slides in a groove a¹.
The slider is provided with lugs d³, d, and d³. Suitable notches or spaces a²
allow of the insertion of these lugs into the box a. The stops b, b, 63, have holes
formed therethrough to enable the lugs on the slider to pass freely, said holes being
sufficiently small so as to stop the plates h.
When a heavy sea strikes the rudder the tiller imparts its motion to the
slider d, the shock being thus borne by the springs c, c', which act simultaneously
and independently in one and the same direction as shown in Figs. 7 and 8, which
ever direction it may be for the time being.
In the modification shown in Figs. 9 and 10 the tiller may be connected to the
slider d by links or such like connections ¹ from lugs i, i or equivalent parts.
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 construction and use of steering apparatus, especially adapted for use with
steam power alternatively with hand power, so as to obviate the ill effects of

page_text: impact of heavy seas on the rudder, and shock to the operating parts, by the
employment of tiller and quadrant so connected as to enable them to convey the
operative motion from one to the other, and thereby to the helm, by means of
springs arranged so that a suitable slider () or its equivalent puts both springs
or sets of springs into compression simultaneously as and for the purpose set forth.
