Improvements in Apparatus for Withdrawing Shavings, Dust and
the like, and for Ventilation.
We, MARTIN ROSE RUBLE, Mechanical Engineer, WILLIAM INGRAM ADAMS,
Gentleman, both of 145, Cannon Street, in the County of London, and CHARLES
RISBEE IORNS, of 11, Kyverdale Road, in the County of London, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements on a former invention for which
Martin Rose Ruble obtained Letters Patent No. 23731 dated the 23rd December
1892.
According to this invention we form the ejector by causing the pipe from the
blower to enter another pipe which is in communication with the chamber from
which it is desired to withdraw shavings or other substances, so that as the air
is blown through the pipe coming from the blower it will form a suction in
the other pipe in order to draw the substances through this pipe.
The blower we prefer to use in connection with the above described ejector
consists in improvements on the blower described in the Specification of a former
Letters Patent granted to Martin Rose Ruble No. 1089 dated the 18th January
1893. The present improvements consist in extending the circular portion of
the partition plates so that such portions may overlap one another, and further
shortening the said partition plates.

Improvements in Apparatus for Withdrawing Shavings, Dust and
the like, and for Ventilation.
We, MARTIN ROSE RUBLE, Mechanical Engineer, WILLIAM INGRAM ADAMS,
Gentleman, both of 145, Cannon Street, in the County of London, and CHARLES
RISBEE IORNS, of 11, Kyverdale Road, in the County of London, 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 follow-
ing statement:
This invention relates to improvements on a former invention for which
Martin Rose Ruble obtained Letters Patent No. 23731 dated the 23rd December
1802

page_text: According to this invention we form the ejector by causing the pipe from the
blower to enter another pipe which is in communication with the chamber from
which it is desired to withdraw shavings or other substances, so that as the air
is blown through the pipe coming from the blower it will form a suction in
the other pipe in order to draw the substances through this pipe. The suction
is caused by the expansion of the air at the end of the pipe from the blower.
The blower we prefer to use in connection with the above described ejector
consists in improvements on the blower described in the Specification of a former
Letters Patent granted to Martin Rose Ruble No. 1089 dated the 18th January
1893. The present improvements consist in extending the circular portion of
the partition plates so that such portions may overlap one another.
And in order that our said invention may be better understood we will now
proceed to describe the same with reference to the accompanying drawing in
which Fig. 1 shews sectional view of the ejector: Fig. 2 end view of same:
Fig. 3 sectional view of the blower.
In Fig. 1a shews pipe from the blower entering another pipe & the end c of
which is in communication with the chamber from which it is desired to with-
draw shavings for example. f shews a web supporting the pipe a.
As the air is blown through the pipe « coming from the blower the expan-
sion of the air at the end of this pipe a causes a suction in the pipe so that the
substances are drawn through this pipe. The arrows shew the course of the cur-
rents of air.
With reference to Fig. 3 the improvements on the blower consist in bending
the circular portion of the partition plates as shewn at d, the straight portions c
of such plates being made slightly shorter than is usual. The parts d, e are
secured between a pair of face plates g by bolts as shown at h. The direction of
rotation is indicated by the arrow i.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. Constructing an ejector substantially as and for the purposes set forth.
2. In apparatus for withdrawing shavings dust and the like and for ventila-
tion, the employment of a blower in combination with an ejector all constructed
substantially as set forth.
