PROVISIONAL SPECIFICATION.
An Improved Interchangeable Rotary Watering and Sanding
Machine.
I, BRIERLEY DENHAM HEALEY of Bamber Bridge in the County of
Lancaster, Civil Engineer do hereby declare the nature of this invention to be as
follows
My present invention is connected with apparatus known as Willacy's Rotary
Sand and Water Spreaders, for which Letters Patent were granted unto Robert
Willacy A.D. 1874 his Specification being No. 2306.
According to my said invention the upper part of the apparatus, which is
differently constructed for sand and water, is readily removed from the lower part
so as to be interchangeable at short notice.
It will be found a great advantage in many places to have the water tank
surmounted in summer and the sand box in winter so that the same gearing may be
more constantly used the year about.
The driving gear is all attached to a lower main framing on which the main
wheels are mounted and to which the shafts are secured at the front.
Above the main framing is a secondary framing which is caused to oscillate upon
its centre or otherwise by means of a suitably screwed shackle so as to balance the
body or load when working upon inclines.
The body which carries the water or sand is moveable and when in use it rests
in cleats upon the secondary framing, which latter may have bearing springs
underneath, and compensating gear for regulating the length of the driving
chains.
The spreaders are always at the same relative position with the surface of the
street, whether working on inclines or upon level roadways, and are driven by bevil
gearing, fitted with suitable clutches.
The water tank is fitted with two flexible outlets leading to distributing tubes
over the rotators which tubes have several holes for outflow. Each outlet has a
valve with fixed cap and moveable sleeve, the latter closing on rubber ring at
upper edge and on rubber seating at lower edge.
When it is required to use the sand box instead of the water tank the latter is
removed and replaced by the former upon the main framing.
The sand box is V-shaped or prismatic in section and has a right and left handed
spiral conveyor across the bottom which delivers the sand through an aperture at
the centre into small elevator buckets which feed the rotators.
The spiral conveyor and elevator are driven by two sets of chain gear from
the inner side of main wheels, which also drive the spreading gear and com-
pensating clutch gear is fixed at each end of elevator driving shaft.
The vertical spindles work upon bronze discs and in suitable bushes which are
interchangeable. The horizontal spindles work in brass bearings which are
secured to iron framing and are interchangeable.
At the back of each wheel hob there is an oscillatory lever, which carries a roller
at one end for guiding and taking up the wear of the driving chains, and at the
other end a stretching screw for adjusting the said chains, all in such a manner as
to allow of the said machines being fitted with bearing springs.
It is obvious that the gearing may be fixed as before stated whether the upper
parts of the apparatus are interchanged or not.

An Improved Interchangeable Rotary Watering and Sanding
Machine.
I BRIERLEY DENHAM HEALEY of Bamber Bridge in the County of Lancaster,
Civil Engineer, 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 present invention is connected with apparatus known as Willacy's Rotary
Sand and Water Spreaders for which Letters Patent were granted A.D. 1874,
his Specification being No. 2306.
According to my said invention the upper part of the apparatus, which is
differently constructed for sand and water is readily removed from the lower part
so as to be interchangeable at short notice.
It will be found a great advantage in many places to have the water tank
surmounted in summer and the sand box in winter so that the same gearing may be
more constantly used the year about.
The driving gear is all attached to a lower main framing on which the main
wheels are mounted and to which the shafts are secured at the front.
Above the main framing is a secondary framing which is caused to oscillate upon
its centre or otherwise by means of a suitably screwed shackle so as to balance
the body or load when working upon inclines.
The body which carries the water or sand is movable and when in use it rests
in cleats upon the secondary framing which latter may have bearing springs
underneath and compensating gear for regulating the length of the driving
chains.
The spreaders are always at the same relative position with the surface of the
street whether working on inclines or upon level roadways and are driven by bevil
gearing, fitted with suitable clutches.
The water tank is fitted with two flexible outlets leading to distributing tubes
over the rotators which tubes have several holes for outflow. Each outlet has a
valve with fixed cap and movable sleeve the latter closing on rubber ring at upper
edge and on rubber seating at lower edge.
When it is required to replace the sand box by a water tank the former is
removed and replaced by the latter upon the main framing.
The sand box is vee shaped or prismatic in section and has a right and left
handed spiral conveyor across the bottom which delivers the sand through an
aperture at the centre into small elevator buckets which feed the rotators.
The spiral conveyor and elevator are driven by two sets of chain gear from the
inner side of main wheels which also drive the spreaders, and compensating clutch
gear is fixed at each end of elevator driving shaft.
The vertical spindles work upon a bronze disc and in suitable bushes which are
interchangeable. The horizontal spindles work in brass bearings which are
secured to iron framing and are interchangeable.
At the back of each wheel hob there is an oscillatory lever which carries a
roller at one end for guiding and taking up the wear of the driving chains and at
the other end a stretching screw for adjusting the said chains, all in such a manner
as to allow of the machines being fitted with bearing springs.
It is obvious that the gearing may be fixed as before stated whether the upper
parts of the apparatus are interchangeable or not.
And in order that this invention may be understood I will now describe it with
reference to the sheet of drawings attached.
Figures 1 and 2 shew the sanding machine and Figure 3 the valve for water tank
outlet.

page_text: The driving gear 1 is attached to the lower main framing 2 on which the main
wheels 3 are mounted and to which the shafts 4 are secured.
Above the main framing 2 the upper or secondary framing 22 which carries the
sand box 13 or water tank may oscillate upon its centres 5 by means of a screwed
shackle 6.
The spreaders 7 revolve on spindles 18, and are always at the same relative
position with the surface of the street, and are driven by bevil gearing 8.
The water tank is fitted when in use with two flexible outlets each of which
has a valve, shewn by Figure 3, with fixed cap 9 and movable sleeve 10 the latter
closing on rubber ring 11 at upper edge and on rubber seating-12 at lower edge.
The sand box 13 has a right and left handed spiral conveyor 14 which delivers
the sand through an aperture at the centre into small elevator buckets 15 which
feed the rotators 7.
The spiral conveyor 14 and elevator 16 are driven by two sets of chain gear 17
from the inner side of main wheels 3 which also drive the spreaders 7.
The vertical spindles 18 work in suitable bushes 19, and carry the rotating
spreaders 7.
At the back of each wheel hob there is an oscillatory lever 20 which carries a
roller 21 at one end for guiding and taking up the wear of the driving chains 17
and at the other end a stretching screw 22 for adjusting the said chains.
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. The method of interchanging a water tank and sand box so as to be used at
different times upon one main framing as herein described.
2. The method of taking up the slack chain occasioned by wearing of the
driving chain as herein shewn and described.
3. The construction of a sand box with a conveyor and elevator as herein shewn
and described.
4. The method of constructing the outlet valves of water tanks as herein shewn
and described.
