PROVISIONAL SPECIFICATION.
Improved Construction of Vehicle for Distributing Sand and other
Small Particles or Material upon Roads or on the Ground.
I, JOSEPH THOMAS PARLOUR, of 166 Fleet Street, City of London, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to a novel construction of sand cart, or vehicle with means,
or appliances for distributing or spreading sand, gravel, or grit upon slippery, ice
covered, or other roads, the object being to produce safe travelling to horses.
For the purpose of my invention, I construct a cart or vehicle with a hopper
formation, into which, sand, gravel, or grit can be placed and then fall on to a screen
or sieve fitting in guides and have a jogging, or to and fro travel imparted to it by
crank, or its equivalent actuated from, or through one of the main bearing, or
travelling wheels, and either direct, or through intermediate gearing. The sand, or
grit thus falls directly on to the road for the full width of the cart or vehicle.
I purpose fitting a blade or spreader, or it may be a fan or blower to the front or
rear, or at the sides of the vehicle, so that the sand or grit can be spread to a distance
and be so scattered over a large area.
The invention is also applicable for distributing soot, bone dust, and other
material, such as phosphates (solid) gas lime and the like for agricultural
purposes.

COMPLETE SPECIFICATION.
Improved Construction of Vehicle for Distributing Sand and other
Small Particles or Material upon Roads or on the Ground.
I, JOSEPH THOMAS PARLOUR, of 166 Fleet Street, City of London, 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:
This invention relates to a novel construction of sand cart, or vehicle with means or
appliances for distributing or spreading sand, gravel, or grit upon slippery, ice
covered, or other roads, the object being to prepare a roadway for safe travelling to
horses.
For the purpose of my invention, I construct a cart or vehicle with a hopper
forination, into which, sand, gravel, or grit can be placed and then fall on to a screen,
or sieve fitting in guides and have a jogging or to and fro travel imparted to it by
crank or its equivalent actuated from or through one of the main bearings or
travelling wheels, and either direct or through intermediate gearing. The sand
or grit thus falls directly on to the road for the full width of the cart or
vehicle.
I purpose fitting a blade or spreader, or it may be a fan or blower to the front, or
rear, or at the sides of the vehicle, so that the sand or grit can be spread to a distance
and be so scattered over a large area.
The invention is also applicable for distributing soot, bone dust and other
material, such as phosphates (solid) gas lime, and the like for agricultural
purposes.

page_text: Figures 1 and 2 are side and sectional elevations respectively.
Figure 3 is a back end view showing the spring arrangement.
Figures 4 and 5 are side elevation and part end view of a modified arrangement
of the working gear in which a jogging motion is given to a screen or distributor
supported under the body of the vehicle.
Figures 6 and 7 are part side elevations of a vehicle by which the sand or grit
can be distributed or spread from the rear by a blower such as a fan, worked by a
spring motor as at Figure 6, or a bellows as at Figure 7 both of which can if desired
be operated from the main driving wheel or wheels.
Figure 8 shows a vebicle with a sifting screen to be operated by hand.
The screen may have the same gauge, or different gauges of perforations to regulate
the sizes of the substances to be distributed.
A is the vehicle, B the bearing wheels. C (Figure 1) is a cam or wiper which
turns with the wheel and lifts the lever D on its pivot pin E whereby the other
end F is depressed for lowering the sieve G, and putting a tension on the spring H
for returning the sieve and the lever to their first positions, said movement from
the pivot G being somewhat sudden which shifts the sand or grit down the sieve
or screen from whence it passes through the apertures in the same.
The end F has a rod working in the slot of M and a pin at the lower part of
the rod is connected to the link L from which the back end of the sieve is hung.
The body of the vehicle is hopper shaped as at Figure 2, the bottom being
provided with a valve I the opening of which can be regulated by the levers J.
The end of the screen is provided with a catch, so that stones which will not pass
through the sieve will be allowed to slide out through the back when the door K is
opened.
The sieve is connected to the spring by links L and the bar by which it is connected
passes through to the outside of the vehicle where it is connected to straps (one on
each side) working within the guides M.
In the foregoing, the motion of the sieve is vertical from the pivot pin G¹ but
according to Figures 4 and 5, the sieve G has a to and fro jogging motion imparted
to it by the crank N, this being driven by gear from the bearing wheels B. The
sieve in this arrangement is suspended by bars P and rollers Q, said rollers working
in slots or recesses to give the sieve freedom of action at all times.
Instead of a sieve being arranged under the vehicle, the material to be distributed
after leaving the valve I may be blown by wind from the pipes R operated by the
fan S, or from the bellows T, Figure 7. The fan can be driven by a spring S
Figure 6.
Where the sand or gravel has to be sifted into grades, I prefer the vehicle to be
according to the arrangement, shown at Figure 8, the screen or sieve being workable
by hand lever U and the length of time in which the sand shall require for being
properly sifted (graded) can be regulated by the screw rod V.
This grade sifter vehicle will be found valuable as a preparatory sifting, so that the
same grade can be furnished to the distributing vehicles, it will be also useful for
sifting operations generally, such as for builders, coal and stone merchants, and others,
the rough material being thrown in at W will be sifted into three grades or
receptacles a, b, c, forming the lower part of the vehicle, the coarsest or unsifted
particles falling from the sieve down the shoot X.
Having now particularly described and ascertained the nature of this. inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The construction of vehicles with sifting, or other distributing arrangements of
mechanism, whereby sand, or other small particles can be spread on roads, or on the
ground, as described with reference to the annexed drawings.
2. The cams on the bearing wheels of a vehicle for effecting the jogging motion
of a sieve for spreading sand, grit, or other small particles of materials on to roads

page_text: or the ground, as set forth and shown at Figures 1, 2, and 3 of the annexed
drawings.
3. In combination with a vehicle for distributing sand, grit, phosphates or the
like, the spring motor for actuating a blower to spread or scatter the sand, or other to
a distance over a large area, as described and as shown at Figure 6 of the annexed
drawings.
4. The means for operating a bellows for blowing or forcing sand, grit, or
other like bodies, as referred to with reference to Figure 7 of the annexed
drawings..
