PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Propelling Pleasure-boats, Life-
boats, and other similar Vessels.
I THOMAS HALLIDAY of St. Anne's Road St. Annes on the Sea Lancashire,
Warehouseman do hereby declare the nature of my said invention to be as
follows:-
The object of this invention is the application to pleasure-boats, life boats and
other vessels of a multiple driving-gear to be operated by several persons
simultaneously.
In performing my invention I apply the motor either to driving a paddle wheel or
a screw propellor. As applied to a paddle wheel I mount a chain wheel upon the
paddle shaft communicating through an endless chain with a similar chain wheel
upon an intermediate shaft working in bearings across the bottom of the boat. This
intermediate shaft is geared by another continuous chain to a series of chain wheels
arranged along the bottom of the boat and parallel to each other-each series being
geared in turn by a chain and wheels to its own driving shaft and operated by a crank
and treadle.
In this manner 1 am enabled to employ the labour of several men to propel the
boat each man having his own driving shaft and all such shafts communicating with
the paddle wheel as aforesaid.
It will be apparent that by having a sliding clutch box on each driving-shaft that
either a brake inay be applied or a reversing action brought into play.
The improvements are equally applicable to driving the propellor shaft of a scrow-
propellor.

Improvements in Apparatus for Propelling Pleasure Boats, Life-
boats, and other similar Vessels.
I THOMAS HALLIDAY of St. Annes Road, St. Annes on the Sea, Lancashire,
Warehouseman do hereby declare the nature of my said 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 this invention is the application to pleasure boats, life-boats and other
vessels of a multiple treadle driving gear to be operated by several persons
simultaneously.
In performing my invention I apply the motor either to driving a paddle wheel or
a screw propellor.
On the accompanying drawings Fig. 1 is a front view Fig. 2 an end sectional view
and Fig. 3 a plan view of my improved propelling treadle gear shewn as applied to
driving a paddle shaft by two persons seated side by side and which gear is capable of
being instantly reversed.
In all three views a is the treadle shaft mounted in the pedestals b rising from a
base plate affixed across the bottom of the boat. This treadle shaft is provided at
each extremity with a pair of treadle cranks whereby revolving motion may be
communicated to such shaft by two persons seated side by side. This revolving
motion is communicated through a pair of parallel intermediate shafts & and e and by
means of chain wheels and endless chains to the paddle shaft f. As illustrated the
larger chain wheel a drives the intermediate shaft d by an endless chain a passing
round the smaller chain wheel e'. The two parallel shafts are in turn geared together
by the endless chain g passing round the equal sized chain wheel or pinion and the
shafte is geared to the paddle shaft by the chain i shewn dotted passing round the
larger chain wheel on to the chain pinion *.
In addition to the endless chain g the two shafts d and e are shewn geared together
by spur gearing consisting of a pair of spur wheels each gearing with an idle inter-
medinte spur wheel j¹ keyed upon the central shaft but I do not confine myself to
using this combined gearing as either the chain or spur gearing may be adopted
separately.
The intermediate shaft e is also fitted with a sliding clutch box k which is capable of
being put into gear with the loose spur wheel gearing with a similar spur wheel l
keyed upon the intermediate shaft d and thus to drive the propelling gear in the
direction of the arrows or by being put into gear with the chain wheel (which also
runs loosely upon the shaft e) to drive the propelling gear in the reverse direction.
It will be apparent that in case of the propelling gear being only required to work
in one direction that one of the intermediate shafts and reversing gear would be
dispensed with and the chain wheel in this case would be mounted direct upon the
intermediate shaft e.

page_text: If it be required to multiply the number of treadle shafts and to drive the paddle
by more than two persons I employ the auxiliary arrangement represented on Sheet 2
and in which Fig. 4 is a front view and Fig. 5 an end sectional view. It will be
observed that this arrangement consists of a treadle shaft m provided at the extremities
with a pair of treadle cranks n and geared by an endless chain o to an intermediate
shaft o¹.
By arranging one of these auxiliary arrangements in front of the main driving
gear hereinbefore described and connecting the intermediate shafts o' and d together
by chains p passing round their respective chain wheels I am enabled to provide a
triple propelling gear suitable for six persons.
This will be more clearly understood by reference to the diagrams Figs. 6 & 7
representing a side view and plan view respectively of a boat so fitted with my
improved propelling gear, the same letters of reference being employed to indicate
the parts corresponding with those illustrated in the previous views and hereinbefore
described.
As applied to driving a screw propellor I gear the shaft d to the propellor shaft by
bevil gearing.
Having thus particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what
I claim is
1st. The improved propelling gear substantially as and for the purpose hereinbefore
described and illustrated on the accompanying drawings.
2nd. In a propelling gear the combination of a treadle shaft and intermediate
shaft or shafts geared together by chain gearing and operating substantially as and
for the purpose liereinbefore described and illustrated on the accompanying drawings.
3rd. In a propelling gear the employment of one or more auxiliary treadle shafts
working in combination with a central reversible arrangement geared to the paddle or
screw propellor shaft substantially as and for the purpose hereinbefore described and
illustrated on the accompanying drawings.
Dated this 26th day of October 1888.
