Improved Means for Transmitting Waste Fibres from Finisher to
Breaker Carding Engines and the like.
We, ROBERT BARNABUS ROBINSON, of No. 10 Liverpool Street, Sherbrooke,
County of Sherbrooke, Province of Quebec, Dominion of Canada, Manufacturer,
and EDWARD PERKINS CONLEY, of No. 113 Market Street, Sherbrooke,
County of Sherbrooke, Province of Quebec, Dominion of Canada, Manufacturer,
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 pneumatic card waste transmitters such as are adapted
to work back waste side ends from finisher cards.
Our invention is embodied in a system which consists of a single blast fan serving
to deliver air into a main pipe extending beneath the card-room floor. From said
main pipe, branch or transmitting pipes are supplied for each side-end; two for
each finisher card. Rising from each branch pipe is a small tube, which serves to
conduct and acts as a feed to lead the side-end into the branch pipe; it being
understood that the side-end is first drawn down said tube and subsequently blown
back to first or second breaker card as is desired.
Our invention moreover consists in an arrangement of co-operating elements by.
which no positive mechanical agencies are employed to seize the side-end in order
to cause the latter to enter the transmitter, and further in instrumentalities by
which back draft in the supply tubes is avoided; likewise in the peculiar
construction of the delivery end of the transmitter pipes whereby the side-end is.
passed to the breaker and transferred without the aid of direct mechanical
agencies.
The drawings represent in Fig. 1, a side elevation of a pneumatic card-waste
transmitter embodying our invention.

pipes.
Fig. 3 is a sectional view enlarged of the delivery tube and transmitter pipe at
the point where the side-end enters the latter.
Fig. 4 is a diagram of our invention as applied.
In the accompanying drawings 2 represents the floor of a card-room in which
are located finisher cards, one of which is illustrated at 3 with condensing rolls.
at 4, where the side-end 5 is formed. At any suitable place is located a blast fan 6 -
and connected therewith is a main air pipe 7 which is preferably beneath the floor
of the card-room, in fact the entire system.is to be below the floor with the exception
of the tubes 8. These latter extend up through said floor and terminate at a point_
in proximity to where the side-ends are formed; said feed tubes serving to convey
the side-ends to the transmitting pipe. These feed tubes are surmounted with
porcelain mouthpieces 20 or other insulating material to prevent the side-ends
from sticking thereto and occasioned by electrical attraction.
As will be seen by reference to Fig. 4 each finisher card is supplied with branch
or transmitting pipes 9, which extend from the main pipe 7 laterally of each finisher
card, one for either side, and said pipes terminate at the first or second breaker card
as is desired. The supply tubes 8 are shown removably mounted in the transmitting
pipes, while a gate 10 is positioned in said pipe at a point in advance of that where
the side-end enters the transmitting pipes. The diameter of the main pipe is to be
of such capacity as will more than supply all the transmitter pipes. Hence air
enters the latter under slight pressure. To prevent such air under pressure of the

page_text: fan from entering the vertical supply tube 8 and so cause a back draft, the latter
are extended into the bore of the transmitter pipes preferably to the center of the
latter. Furthermore the main transmitting portion is enlarged in diameter at a
point beyond the point of entrance of the supply tubes. The gate 10 is adjustably
mounted and operated by a rod 12, which extends through the floor 2 of the
card-room.
The effect of the above arrangement of elements is such that the passage of the air
transversely across the bottom of the supply tube 8. naturally tends to draw and
suck down air after the action of an injector. To increase such action the gate is
employed to reduce the bore of the branch pipe before it reaches the extremity
of the supply tube; hence the air passes by with increased velocity, while after
such air has performed this duty and entered the enlarged portion it is not sufficient
in volume to fill such portion, consequently more air rushes down the supply tube
to make up the deficiency. In this manner no mechanical agencies are required to
grasp the side-end, but the latter is drawn and sucked down the tube 8 and thence
conveyed in an unbroken condition to the breaker card.
The discharge of said waste ends into the breakers is another important feature
in our invention. Necessarily in order to create a suction down the supply tubes 8,
the transmitter pipes must have open ends; therefore to allow escape of air
and yet compel the side-ends to pass upon the periphery of the breaker cylinder 13
perforations or vents are created in the walls of the pipe as shown. Moreover to
cause the side-ends to properly engage the card clothing a guide-plate 15 is
attached to said pipe and curved to conform to the periphery of the cylinder, while
the perforated end portion 16 and the guide-plate are pivotally attached at 17
in order to afford adjustment and enable the delivery end to be properly positioned
with respect to said cylinder. This vertical portion 18 may be made of two
parts to telescope, and thus provide for vertical variation of the breaker cylinder
above the floor.
In case the supply tubes should become obstructed for any cause, their clearance
is readily obtained by lifting the gate 10 up and allowing the air full vent through
the smaller length of the transmitter pipe with the result that the air backs up
and escapes upwardly through the supply tubes at the same time forcing out and
expelling the material, accidentally caught or wedged therein.
By means of our improved arrangements, a single blast fan will serve to supply
pipe systems under air pressure for a large number of carding engines and at a very
small cost, while the operating parts for transmitting the waste-ends from the
condensing rolls to the cards are reduced to the fewest possible, and moreover are
regulated and controlled with little or no trouble.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :
1st. The system for transmitting waste side-ends from finisher cards and which
consists in a single blast fan, a main pipe, a series of transmitting pipes therefrom,
two for each card, and tubes which supply waste side-ends to the transmitting
pipes and means for regulating the air blast through the transmitting pipes,
substantially as and for purposes explained.
2nd. The combination, with a series of carding engines and groups of condensing
rolls therefor, of a single blast fan, a main supply pipe, a series of branch
transmitting pipes one for each side of the engine, supply tubes from the
condensing rolls to the transmitting pipes and gates to control the air blast,
substantially as specified.
3rd. In combination with a carding engine having a series of condensing rolls, a
single blast fan, a túbe system for forced draft; one end of the system being united
with the fan, the other end terminating in rear of the card, and a gate for regulating
the blast through the tube system substantially as stated.
4th. The combination with a series of carding engines, and groups of condensing

page_text: rolls therefor, of a single blast fan, and a main supply pipe, a series of branch pipes
with perforated terminals and composed of two lengths of different diameters,
supply tubes from the condensing rolls to the transmitter pipes for passage of side
ends, and a gate between the main pipe and the delivery end of the supply tubes,
all operating substantially as explained.
5th. In combination with a carding engine, its condensing rolls, and supply tubes
for passage of side-ends, a main pipe for air blast, transmitting or branch pipes
from said main pipe to the breaker, pivotal perforated extremities for said
transmitting pipes, said pipes being contracted at or near the main air pipe and
receiving the lower extremities of the supply tubes, and a gate mounted in said

6th. The combination with a single blast fan, and a main pipe therefrom, of a
series of transmitting pipes, composed of two portions, an enlarged terminal portion
provided with a pivotal extremity with wall perforations, a contracted portion

projecting within the bore of the latter, and a gate between the extremity of the
supply tube and the main pipe, substantially as described.
7th. In combination with a finishing card, its condensing rolls, a main pipe for
