Engineers Mechanical Draughtsman 3 Whitehall Pl. Westminster do hereby declare
the nature of my Invention' for AN IMPROVED COMBINED MUD RECEIVER AND
HYDRAULIC LIFT to be as follows:-
The nature of the Invention is for the purpose of receiving and raising mud and
sweepings from the streets with the aid of machinery, and then allowing it to fall
by gravitation in one mass direct into dung carts, and thereby effecting a great
saving of time, labour, filth and inconvenience.
It is composed of one hydraulic apparatus fixed below the level of the pavement,
in a convenient position for the scavenger. A suitable cast iron frame and cover
will be provided independent of the apparatus forming the curb of the pavement
in this frame an opening will be made flush with the street to allow the mud or
dust deposit to be swept freely into a galvanized wrot iron receiver, or jack
head, supported by the ram head of the lift, this receiver being of a square oblong.
shape with a sloping bottom of 30° inclination is guided in its travel with guides
bolted to the fraine. When the receiver is raised full, (after raising the cover of
the frame,) a suitable flap door is let go by releving a few catches operated by a
handle, the whole contents will slide comfortably into a low dung cart, of the
semicircular tank principal, the receiver then falls to its original position, the
frame door closed, and sweeping and filling repeated. This operation not exceeding.
three minutes, is worked by turning a key, applied to a valve, of a suitable
character connected by small wrot iron pipes to the water mains below the streets,
the pressure of water admitted to the lift by turning one way for raising and the
opposite way for lowering, exhausting the waste water into the brick sump
formed to take the apparatus. Ample provision is made for influx of water caused
by the rain, to flow over the receiver, and drain into the main sewer in the usual
manner, through drain pipes.

page_text: WILLIAM BOOTH POWELL, 3 Tintern Street Ferndale Road, Brixton S.W. London,
Engineers Mechanical Draughtsman 3 Whitehall Pl. Westminster do hereby declare
the nature of my Invention for AN IMPROVED COMBINED MUD RECEIVER AND
HYDRAULIC LIFT and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:—
My Invention consists in improvements in, and relating to machinery or
apparatus for receiving and raising street mud, or dust, or other refuse, and raising
it by hydraulic power to such a level as to command a low mud cart, and allowing
it to slide by gravitation, by releasing a flap door, or by the process of tipping a
receiver, provided with two trunnions and supported on a fork.
The said Invention is illustrated in the accompanying Drawing.
Figure 1 is a transverse section of the apparatus showing the receiver in its
natural or stationary position, below the pavement, and the same raised to a height
commanding the cart, &c.
Figure 2 is a front view of the cast iron frame showing the opening for the mud
or dust to pass into the receiver, it also forms the curb of the pavement and is
fitted with a wrot iron cover to enclose the apparatus.
Figure 3 is a longitudinal section showing the pipe connections, cock, and
key, &c.
Figure 4 is a section of another form of receiver provided with trunnions and
supported on a fork crosshead, for the purpose of tipping.
Figures 5 and 6 are large scale sections of the ram aud cock. Like letters indicate
the same throughout the Drawing,
To carry the said Invention into practice I propose that boy or female labour
should be employed at intervals during the day sweeping or scraping with broad
base tools towards the receptacles called receivers pitched say 40 or 50 yards apart.
The receivers standing below the level of the street, the mud or refuse when swept
towards them will flow, or fall by gravitation into the same, thereby disposing of
all refuse, hiding it from public gaze, and retaining all solid matter, until required
to be emptied into carts, and this is effected by constructing the apparatus in the
following manner.
-
To make the apparatus complete a suitable cast iron square frame D and hinged
cover plate C, is provided, making good the pavement' and forming the curb, this
frame is cast with an opening A level with the street and made to slope inwards,
and finished with a lip to overlap the receiver B. The receiver, may be made with
either galvanized wrot iron or steel plate and is constructed with a sloping bottom
of 30° or 35° with the horizon. A balanced plate E is provided and fixed at its.
top, this plate answers three purposes (viz.) (1) To guide the mud.into the centre
of the receiver. (2) When full prevents the mud from flowing over the lip F.
(3) To act as a stop under the cast iron lip this preventing the recever rising in
case of any leakage or inadvertance with the cock G.
The lip Facts as an overflow, the full width of the receiver, to. allow of any
influx of water caused by heavy rain to pass into the drain. The muddy water
first flowing over the plate E into the receiver B and over the lip F thereby
allowing the heavy or solid matter time to settle at the bottom, and the water to
flow over the lip F and into the main drain, the plate E also preventing all lighter
matter floating on the surface from passing into the drain. The flap door M
provided for discharging the receiver is hinged at the bottom and held at the top

page_text: with two catches, these catches are arranged on the outside, and each provided
with a lever and secured to a bar passing through the receiver, at the end of each
lever a chain N N is secured and connected to the sides of the door. The act of
releasing the catches with either handle, allows the pressure behind the door to
open it, the chains checking it when in line with the bottom of the receiver B,
thereby allowing the contents to slide out evenly into the cart.
The receiver B may be made to any size and proportion most suitable to the
requirements, and is supported by the hydraulic ram crosshead H.
The apparatus being encased in a brick sump a hole at the bottom is bored to a
size and depth sufficient to take the hydraulic ram and case I.
Between the case I and the water company's main under the level of the street,
a connection is made with a one inch wrot iron pipe J and a gun metal three
branch cock. G to suit, for the purpose of conveying, the water pressure in the
main to the underside of ram.
The operation of raising the receiver when required to be emptied, will be
performed by the man in charge of the cart who shall have a long spindled key K in
his possession to apply to the cock G, fixed about one foot below the level of the
pavement, the key is guided through a hole cast in the frame D. The cock G
being easily accessable and removed at any time in case of repairs. The mud cart L
is next drawn immediately opposite the apparatus. The door C is then raised to a
vertical position and held automatically with the aid of two links b¹ 61, these links
will also act as guards to prevent accident to foot passengers. The balanced plate E
is then pulled inwards, the key K should be turned a quarter of a circle, thus
admitting the pressure under the ram, the pressure of water being constant the
receiver is raised to a height sufficient to command the cart and will be kept
stationary in that position with the pressure. The ram having a swell on the
bottom acts as a stop against the top box, and is guided in its travel with a
V shaped guide cast internally on the case as seen in Fig. 5. The flap door M
which is made to act as a shoot is then released by releaving the two catches, the
pressure behind it causing it to fall simultaneously and it is checked in its fall by
the two chains previously mentioned. The contents will then slide evenly (if not
too congealed) into the cart causing no emission of dust filth or inconvenience.
Should any remain behind with the aid of a small scraper, the residue can be easily
cleared out. The receiver being now empty the door M is closed by hand, and
held automatically with the two catches. The key K is then turned in the opposite
direction-shutting off the water pressure and allowing the water under the ram
to escape and drain into the sump through the third branch of the cock. The
receiver at the same time decending slowly to its original position. The balanced
plate E is then pulled outwards until it rests under the lip of the frame D the wrot
iron cover is lowered by releaving the links b b. The time occupied in this
operation should not exceed three or four minutes and the quantity of water
consumed depends on the pressure. The receiver B not being entirely water tight
allows a partial leakage to go on when charged with mud, and thereby allowing it
to subside at the bottom. The direct acting hydraulic ram possesses no great
novelty except a simple mode of guiding the ram with a V shaped guide cast
internally on the case as before mentioned. The ram being swelled at the end
nearly as large as the case, and by filing a notch to fit the guide it acts as a guide
block and further as a stop when coming in contact with the top box.
The brick sump is finished with a sloping bottom of 30° or 35° parallel with the
bottom of the receiver formed of concrete, imbedding the stuffing box, thereby
strongly securing the whole apparatus.
At the bottom of the sump the usual self acting flap door and drain pipe are
arranged leading to the main drain, with this arrangement it can be easily seen
that no accumulation of mud or dust can lodge at the bottom the waste water from
the ram washing away immediately any accumulation that might accidently fall
to the bottom.
