Improvements in Induction Apparatus for Withdrawing Shavings,
Dust, and the like, and for Ventilation.
We, MARTIN ROSE RUBLE, President of The Ruble American Blower aud
Injector Company and THEODORE RUNYON GUILD both of 282 Halsey Street,
City of Newark, in the County of Essex, and State of New Jersey U.S. America,
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:-
The object of our invention is the construction of a new and useful induction
apparatus, whereby air, gases, shavings, dust or similar matters may be sucked up
and discharged by means of the passage of a current of air.
In the drawings, similar letters indicate similar parts throughout the different
views.
Fig. 1. is a side view of the improved induction apparatus, with certain portions
broken away;
Fig. 2. is a cross section on the line - of Figure 1, and,
Fig. 3. a cross section on the line y-y Figure 1.
In said drawings, a represents, an elliptical and conical case or shell, one end of
which is closed by a partition and the other end terminating in a pipe or discharge
tube c.
Entering this case a is an air pipe or tube i, leading from a blower or other
suitable air forcing apparatus. One end of this pipe terminates some distance
from the end of pipe c and beyond the end of case a; the diameter of the pipe or
tube i is less than the diameter of the discharge c.
Entering the closed end b of case a are the suction tubes or pipes g and h, leading
from the places where the air, gases, dust, shavings or similar matters to be removed,
are situated.
Between the walls of the case a and tube i may be placed partitions m, thus
dividing the space in said case a into two separate compartments into which the
tubes g and h, enters. The diameter of the dust conveying tubes 9 and h, is less
than that of the compartment at the point where the tubes enters, but at the
discharge end of said compartment or at the point where the compartment enters
the tube €,
the area of the compartment and of the tubes g and h, (combined) are
approximately equal.
The partition forms au air tight joint about the tubes g, h, and i.
The operation is as follows. Air is forced into the tube i by means of a blower
or any other suitable means in the direction indicated by the arrows.
The passage
of the air from the end or outlet of said tube into the tube c, creates a vacuum or
suction in the latter and also in the case a, and tubes g and h, thereby generating a
strong current in said tubes, in the direction indicated by the arrows, that is to say
towards the discharge end of the tube c. The intermingling of the currents set up
in the tubes y and within the case a is prevented by the partitions m, and each
current passes separately through the case a into tube c. This construction is
necessary when more than one tube 9 (or h) is used, to confine within each com-
partment, into which said tube discharges, sufficient suction to remove the debris
or other matters.
It will be understood that there may be arranged a series of one or more debris
conveying tubes g or h, (two being shown in the drawings simply for example) and
that each tube may lead to separate points to remove or carry one or more matters
into the discharge c. It is also to be understood that the form of the case a is
made ellipsoidal simply for convenience and that any form of case may be used

page_text: provided the same is flaring or bell shaped; the greatest diameter being at the
point of entrance of the suction tubes and the smallest at the point of discharge
into tube c.
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:
1-In an induction apparatus the combination of the air tube i, leading from a
suitable air forcing apparatus, with the funnel or trumpet shaped case a enclosing
said tube i and closed at one end and ending in a discharge tube c, and with a
series of one or more suction tubes g and h, entering the closed end of said case,
and adapted to convey gas, dust, shavings or similar material substantially as
described.

2-The combination of the air conveying tube i, flaring case a and discharge
tube C, with the suction tubes g and entering the closed end of said case a and
designed to convey gas, dust, shavings, etc., to said case a, and with the partitions m
separating said case a into separate compartments into each of which one of said
tubes gor h enters, substantially as and for the purposes set forth.
3-In an induction apparatus a case into which the suction tubes discharge,
divided by suitable partitions into compartments corresponding to the number of
suction tubes employed, substantially as described.
