Improvements in Dust and like Carts or Vehicles, applicable also
for Scavengering purposes.
I, JOHN CHALMERS, of the Firm Chalmers and Co., of High Street, Redhill,
County of Surrey, Cart and Van Builders, do hereby declare the nature of this
invention to be as follows:
-
This invention relates to a novel construction and method of operating cer-
tain flap or like covers on the roof of a dust or like cart, whether it has two or
four wheels, also to appliances by which the tail of such a cart can be actuated
for the discharge of the dust, such as on a heap or down a shoot.
For the purposes of my invention, I employ a fixed roof to a dust or like cart,
said roof having one or more openings in it, each provided with a flap so hinged
that it can be thrown up by an outside hand lever and simultaneously raise two
side Haps to form a kind of hopper or hood to expose the opening or openings
ready for the contents of a basket or sanitary dust bin to be shot through a
reverse movement of the hand lever closing the flaps and so preventing the escape
of light dust.
The hand lever is in connection with a V or cranked arm or arms and it or
these partake of a swing or circular motion to raise the flaps which preferably
only rest upon the crank and actuate it or them by a sliding action, the flap or
flaps never going beyond a vertical position or against stops to limit the travel.
The flap or flaps may be in parts and hinged for folding.
The tail board or back is operable by a second hand lever which by its con-
nection to cranks can be thrown bodily rearwards from the cart and be then
thrown upwards from top hinges as to be clear of the cart body for free discharge
of the contents when the body is tilted.
Directly under the tail board, a tray is fitted for catching any escaping liquid,
which tray is capable of removal for being emptied as required.

[Price 8d.]

page_text: 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 and method of operating cer-
tain flap or like covers on the roof of a dust or like cart whether it has two or
four wheels, also to appliances by which the tail of such a cart can be actuated
for the discharge of the dust such as on a heap or down a shoot.
The invention is shown on the annexed drawings.
Figure 1 side elevation of a two wheel dust cart with flaps closed.
Figure 2 back end view of cart body with the tail board closed.
Figure 3 side elevation of cart with flaps open.
Figure 4, front of cart body showing the flaps up on one side of the roof by
the swing action of the hand lever.
For the purposes of my invention I employ a fixed roof A to a dust or like
cart, said roof A having one or more openings in it, each provided with a flap B
so hinged that it can be thrown up by an outside hand lever C and simultaneously
raise two side flaps D, D, to form a kind of hopper or hood to expose an opening
ready for the contents of a basket or sanitary dust bin to be shot through, a
reverse movement of the hand lever C closing the flaps B, D, and so preventing
the escape of light dust.
The hand lever C partakes of a swing or circular motion to raise the flaps B, D,
and preferably rests upon a crank or catch E to hold the flaps open. The fall
flap B has at its free corners a couple of pintles or universal joint appliances
connecting-the-end flaps D, D, and as the flap B is being raised the upper halves
of the flaps D, D, are lifted and then the lower halves are lifted, -the-two-halves
being jointed accordion fashion.
The catch of the tail board or-back-G is-releasable by a hand lever H for
the tail G to be thrown outwardly from top hinges I, I for free discharge of the
contents when the body is tilted.
The hand lever C is on the end of a square or other rod movable in sockets
and eyes secured to the roof A and each of said rods has affixed the lugs to which
the flap B is secured so that said Hap 13 can be turned up and be let down by
the movement of the lever C-to open-or-to-close_up_the opening in the roof A.
The tail piece G has a chain or its equivalent say, a wire rope J affixed this
being led through a guide eye a and pulley over the roof A to a pulley b and
from thence down to the shafts frame where it is attached so that when the cart
has to be "tipped" the catch Fis first released and the tail board freed, then
the catch K is released and on the tilting of the body the chain J becomes taut
and pulls the tail open whether the flaps B, D, be open or closed.
I have shown the flaps and their attachments in pairs to enable either side of
the cart to be opened for loading purposes.
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. A dust cart with one or more roof openings each having a hinged fall
flap B to which and to the roof end jointed flaps D), D, are secured and having an
opening and closing action with and by said fall flap B as and for the purposes
specified, the arrangement being substantially as represented.
