County of Middlesex, for the Invention of "IMPROVEMENTS IN APPARATUS
COMBINED WITH CARTS OR OTHER VEHICLES FOR DISTRIBUTING SAND,
GRAVEL, OR OTHER MATERIALS ON TO TRAMWAYS OR OTHER ROADS."
PROVISIONAL SPECIFICATION left by the said Henry William Barstow at
the Office of the Commissioners of Patents on the 23rd July 1879.
HENRY WILLIAM BARSTOW, of 27, Regent Street, in the County of Middlesex.
"IMPROVEMENTS IN APPARATUS COMBINED WITH CARTS OR OTHER VEHICLES FOR
DISTRIBUTING SAND, GRAVEL, OR OTHER MATERIALS ON TO TRAMWAYS OR
OTHER ROADS."
This Invention has for its object improvements in apparatus combined with carts
or other vehicles for distributing sand, gravel, or other materials on to trainways
or other roads.
Upon the boss of one of the travelling wheels of a cart containing the sand,
gravel, or other materials to be distributed a cog wheel is mounted, which takes
into and drives a toothed pinion fixed on the end of an axis supported in bearings
below the bottom of the cart or vehicle. A crank fixed on the other end of the
said axis gives a reciprocating motion by means of a connecting rod to a box or
receptacle with a perforated bottom or sieve at the tail or back end of the cart,
the distributing box or sieve being suspended by links attached to the cart or
conveyance.
.
The pinion which actuates the sieve can be thrown into and out of gear with the
driving wheel by a slide having a forked arm which engages with a clutch.
The sand, gravel, or other material is delivered into the distributing box or sieve
from the body of the cart or vehicle through an opening in the bottom of the cart,
the width of the opening being regulated by a hinged door at the back, and the
bottom of the cart is arranged or formed with an inclined surface, so that the sand,
gravel, or other material may slide freely therefrom.
The perforated bottom of the box or sieve is advantageously formed of two
perforated plates or surfaces arranged one above another, the upper one being formed

page_text: in two parts or halves. The holes or perforations when placed opposite to each
other correspond so as to afford the fullest extent of delivery of the sand or gravel,
but when the upper plates are moved side ways the width of the openings can be
closed to any desired extent so as to regulate the quantity and fineness of the sand
or gravel distributed therefrom. The cart or vehicle may be drawn by animal,
manual, or other motive power.
I will now describe another arrangement of apparatus for distributing sand,
gravel, or other materials on to tramways or other roads in accordance with my
Invention.
In this arrangement a hopper is mounted on a frame supported on the travelling
wheels of a carriage. On the boss of one of the wheels a pulley wheel is fixed,
which gives motion by means of a strap or band to a pulley fixed on the end of an
axis, on the other end of which a pulley is fixed, a band on which gives motion to
a pulley on the axis of a revolving dish formed with radial ribs, on to which the
sand, gravel, or other material falls from the hopper in a regulated stream, and is
thus distributed in all directions, except where the edge of the dish is surrounded
by a guard or shield to prevent its discharge at any particular part. The extent
of distribution may be regulated by the speed at which the dish is driven.
The sand or other materials, if desired, may be delivered from the hopper by
means of a screw-revolving arm or other suitable mechanical contrivance.

page_text: Figure 1 (Sheet 1) shows an underside view of a cart having apparatus combined
therewith or applied thereto for distributing sand, gravel, or other materials on to
tramways or roads in accordance with my Invention.
Upon the boss of one of the travelling wheels of the cart A containing the sand,
gravel, or other materials to be distributed a cog-wheel a is mounted, which takes
into and drives a toothed pinion b fixed on the end of the axis b¹, supported in
bearings 6s below the bottom of the cart or vehicle A. A crank pin 6s fixed on the
other end of the axis b¹ gives a reciprocating motion by means of a connecting rod c
to a box or receptacle d, with a perforated bottom at the tail or back end of the
cart, the distributing box or sieve being suspended by links d', d, attached to the
cart or conveyance, as shown.
The pinion 6 can be thrown into and out of gear with the cog-wheel a by the
slide 6 having a forked arm which engages with the clutch 65 on the axis b¹.
The sand, gravel, or other material is delivered into the distributing box or
sieve d from the body of the cart or vehicle through an opening in the bottom of
the cart, the width of the opening being regulated by a hinged door at the back,
and the bottom of the cart is arranged or formed with an inclined surface, so that
the sand, gravel, or other material may slide freely therefrom. The cart or vehicle
may be drawn by animal, manual, or other motive power.
The perforated bottom of the box or sieve d is advantageously formed, as shown
by the section at Figure 2, and consists of two perforated plates or surfaces arranged
one above another, the upper one being formed in two parts or halves.
The holes or perforations when placed opposite to each other correspond so as
to afford the fullest extent of delivery of the sand or gravel, but when the upper
plates are moved side ways by turning the screws d*, d*, the width of the openings
can be closed to any desired extent so as to regulate the quantity and fineness of
the sand or gravel distributed therefrom.
I will now describe another arrangement of apparatus for distributing sand,
gravel, or other materials on to tramways or other roads in accordance with my
Invention.
Figure 3 (Sheet 2) shows a side view, Figure 4 a back view, and Figure 5 a plan
of a hand machine suitably arranged with apparatus to distribute the sand, gravel,
or other materials on to tramways or other roads by centrifugal force.
g is a hopper mounted on a frame g¹, supported on the travelling wheel h. On
the boss of one of wheel h a pulley wheel i is fixed, which gives motion by
means of a strap or band 2 to the pulley fixed on the end of the axis j, on the
other end of which a pulley is fixed, a band on which gives motion to a pulley k¹
on the axis of the revolving dish k formed with radial ribs k², as shown in section
and plan in Figure 6, on to which the sand, gravel, or other material falls from the

page_text: .
hopper g in a regulated stream, and is thus distributed in all directions, except
where the edge of the dish is surrounded by a guard or shield to prevent its discharge
at any particular part. The extent of distribution may be regulated by the
speed at which the dish k is driven. The sand or other materials, if desired, may
be delivered from the hopper g by means of a screw revolving arm or other suitable
mechanical contrivance.
Figure 7 shows a side view, and Figure 8 a back end view of a similar apparatus
to that previously described, toothed gearing being employed in this arrangement
to give motion to the revolving disk k, as will be readily understood on examining
the Drawing.
In order to ensure the constant delivery of the sand or gravel a series of twisted
arms are mounted on the axis 7, revolving within the lower part of the hopper g.
Motion is communicated to the axis 7 by means of a toothed wheel h¹ on the boss
of the travelling wheel h, which takes into and drives the toothed wheel 2 fixed on
the axis 7.
Other mechanical means may be employed in accordance with my Invention for
ensuring the delivery of the sand, gravel, or other material from the hopper g if
required.
Having thus described the nature of my Invention, and the manner of per-
forming or carrying the same into practice, I would remark that I do not claim
any of the parts separately, which are well known and in common use, but what I
claim is,―
First. The improved arrangement, combination, and application of apparatus to
carts or other vehicles for distributing sand, gravel, or other materials on to tram-
ways or other roads by means of a perforated surface or sieve d, substantially in the
manner and for the purpose herein before described and represented in Figures 1
and 2 (Sheet 1) of the Drawings hereto annexed.
I also claim the method of regulating the size of the perforations in the sieve d
by means of a sliding plate, substantially as described with reference to Figure 2
(Sheet 1) of the Drawings annexed.
Secondly. I claim the improved arrangement, combination, and application to
carts or other vehicles of apparatus for distributing sand, gravel, or other materials
on to tramways or other roads by means of a revolving dish or disk k, substan-
tially in the manner herein before described with reference to Figures 3, 4, 5, 6, 7,
and 8 (Sheets 2 and 3) of the Drawings hereto annexed.
In witness whereof, I, the said Henry William Barstow, have hereunto set
my hand and seal, this Twenty third day of January, in the year of our
Lord One thousand eight hundred and eighty.
