PROVISIONAL
SPECIFICATION.
Improvements in the Discharge of the Spiral Conduits or Coils in
Carburetting Apparatus.
I, ADOLPHE ISIDORE VAN VRIESLAND, of 78, Sarphatistraat, Amsterdam, Nether-
lands, Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in carburetting apparatus, which
formed the subject of Letters Patent granted to me No. 16907 dated 17 July
A.D. 1897 and its object is, to effect the discharge of non evaporated hydrocarbon
from each one of the spiral conduits separately into the compressing chamber
of the apparatus.
For this purpose I divide the hollow journal of the drumshaft by partitions into
as many compartments, as there are spiral conduits, so that each conduit dis-
charges through its own compartment directly into the compressing chamber.
By introducing these partitions a disadvantage would in so far arise, as an
equalisation of pressure of the discharged gases would not already commence in
the hollow journal, a fact which takes place in the former construction.
To overcome this defect, I provide openings in the partitions for the gases to
pass through, and so locate these openings that the discharged liquids cannot meet
them in their efflux. I thus allow the gases to regulate equal pressure in the
hollow journal.

Improvements in the Discharge of the Spiral Conduits or Coils in
Carburetting Apparatus.
I, ADOLPHE ISIDORE VAN VRIESLAND, of 78, Sarphatistraat, Amsterdam, Nether-
lands, 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 improvements in carburetting apparatus, which
forms the subject of Letters Patent granted to me No. 16907 dated 17 July
A.D. 1897 and its object is, to effect the discharge of non evaporated hydrocarbon
from each one of the spiral conduits separately into the compressing chamber
of the apparatus.
For this purpose I divide the hollow journal of the drumshaft by partitions into

page_text: as many compartments as there are spiral conduits, so that each conduit dis-
charges through its own compartment directly into the compressing chamber.
By introducing these partitions a disadvantage would in so far arise, as an
equalisation of pressure of the discharged gases would not already commence in
the hollow journal, a fact which takes place in the former construction.
To overcome this defect, I provide openings in the partitions for the gases to
pass through, and so locate these openings that the discharged liquids cannot meet
them in their efflux. I thus allow the gases to regulate equal pressure in the
hollow journal.
The invention is illustrated in the annexed drawings, Figure 1 being a cross
section, and Figure 2 a longitudinal section, that part of the apparatus which has
nothing to do with the present invention being cut away.
Band J are respectively the drum chamber and the compression chamber, into
which the cylinder is divided.
These
In B revolves the drum around which are wound the conduits c.
conduits open at one end (not shown in Fig. 2) into the drum chamber, and at
the other end by radial conduits c¹ into the box b.
In order now to prevent the non evaporated hydrocarbon delivered by one of the
conduits c¹ into the box 6 to pass directly into one of the other conduits which
opens into the same box, I divide this box by partitions a into as many compart-
ments as there are conduits c¹ so that each of the conduits discharges the still
liquid hydrocarbon through its own compartment directly into the compression
chamber.
For the purpose of mixing together already within the box 6 the evaporated
hydrocarbon delivered therein by the conduits c I provide openings d in the par-
titions and locate these openings so that they are not met by the discharged
liquid.
M represents the expansion valve at the gas outlet and N the liquid return
valve both of which are described in my patent before referred to.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, I declare that what I claim is:-
1. In a carburetting apparatus the combination with a cylinder divided by a
partition into two chambers of a rotary drum mounted in one of the said cham-
hers, a series of conduits helically wound around said drum and opening at one
end into the drum chamber, a box arranged at the end of the drum into which
open the other ends of the conduits, and partitions in said box dividing the same
into compartments which open directly into the second chamber, essentially as
and for the purpose described.
2. In a carburetting apparatus the combination with a cylinder divided by a
partition into two chambers of a rotary drum mounted in one of the said chambers,
a series of conduits helically wound around said drum and opening at one end
into the drum chamber, a box arranged at the end of the drum into which open
the other ends of the conduits, partitions in said box dividing the same into com-
partments which open directly into the second chamber, and openings provided
in the said partitions, essentially as and for the purpose described.
