Year: 1880

page_text: LETTERS PATENT to William Mooney, of Ringsend Road, in the County
Dublin, Ireland, for an Invention of "IMPROVEMENTS IN APPARATUS FOR
EXHAUSTING THE HOT AIR, DUST, OR OTHER REFUSE FROM. MILLSTONES,
PURIFIERS, OR SMUT MACHINES."
PROVISIONAL SPECIFICATION left by the said William Mooney at the
Office of the Commissioners of Patents on the 17th July 1880.

"IMPROVEMENTS IN APPARATUS FOR EXHAUSTING THE HOT AIR, DUST, OR
OTHER REFUSE FROM MILLSTONES, Purifiers, OR SMUT MACHINES."
My Invention has reference to the construction and arrangement of effectivo and
simple apparatus for exhausting hot air, dust, or other refuso from millstones,
purifiers, or smut machines, and for separating from the air current the dust carried
along by same.
To this end I construct a closed box of suitable size and material divided into
Within
two compartments by a partition placed vertically in the centre of same.
each of these compartments, both of which communicate with the millstone case, is
suspended & flour dust separator consisting of a light framework or cage covered
with flannel or other suitablo material. Through the meshes or pores of this cage
or separator the air coming from the millstones is drawn by an exhaust fan, the
dust being retained on the outside of the flannel covering.
For the purpose of preserving the meshes or pores of the flannel or other covering
open and allowing the air to pass freely through I cause the cage or separator to be
automatically shaken at certain intervals, whereby the dust adhering to the flannel
This automatic
is thrown off and falls into a bag suitably placed to receive same.

page_text: operation is performed by means of a vertical rod, one end of which is attached to
the lower part of the cage or separator, and the other end passing through the upper
face of the box is attached to an oscillating lever, the free end of which latter is
brought in contact with a rotating cam disk at regular intervals, whereby the
shaking motion is imparted to the cage or separator. These cam disks are actuated
by ordinary driving gear. The interior of each cage or separator communicates
with the exhaust fan by a pipe provided with a throttle valve, which latter is acted
upon by mechanism so arranged that while the shaking operation is going on in one
compartiment of the box the suction through same is cut off, while at the same time
the draft continues through the other compartment. Thus each cage or separator 1
is alternately shaken at stated intervals, while the exhaust on the stones continues
unbroken.

the said William Mooney in the Great Seal Patent Office on the 17th January
1881.

"IMPROVEMENTS
IN APPARATUS FOR EXHAUSTING THE HOT AIR, DUST, OR OTHER REFUSE FROM
MILLSTONES, PURIFIERS, OR SMUT MACHINES."
My Invention has reference to the construction and arrangement of effective and
simple apparatus for exhausting hot air, dust, or other refuse from millstones,
purifiers, or smut machines, and for separating from the air current the dust carried
along by samo.
To this end I construct a closed box of suitable size and material divided into
two compartments by a partition placed vertically in the contre of same. Within
each of these compartments, both of which communicate with the mill stone case,
is suspended a flour dust separator, consisting of a light framework or cage covered
with flannel or other suitable material. Through the meshes or pores of this cago
or separator the air coming from the mill stones is drawn by an exhaust fan, tho
dust being retained on the outside of the flannel covering.
For the purpose of preserving the meshes or pores of the flannel or other covering
open and allowing the air to pass freely through, I cause the cage or separator to
be automatically shaken at certain intervals, whereby the dust adhering to the
flannel is thrown off and falls into a bag suitably placed to receive same. This
automatic operation is performed by means of a vertical rod, one end of which is
attached to tho lower part of the cage or separator, and the other end passing
through the upper face of the box is attached to an oscillating lever, the free end
of which latter is brought in contact with a rotating cam disk at regular intervals,
whereby the shaking motion is imparted to the cago or separator. The interior of
each cage or separator communicates with the exhaust fan by a pipe or shoot
provided with a throttle valve, which latter is acted upon by mechanism, so that
while the shaking operation is going on in one compartment of the box the suction
through same is cut off, while at the same time the draft continues through the
other compartment. Thus each cage or separator is alternately shaken at stated
intervals while the exhaust on the millstones continues unbroken.
In order that my Invention may be more readily understood and carried into
practice I will describe the accompanying Drawings.
Fig. 1 represents a front elevation of the mechanism for operating the throttle
valves and oscillating levers, showing a portion of the closed box above described.
Fig. 2 is a top view of same.
Fig. 3 is a side view of the apparatus complete; and
Figs. 4 and 5 are detail views, hereinafter more fully described.
Like letters indicate corresponding parts in all the views. A, A, represents the
box which is divided into two vertical compartments, as described; B is the driving
shaft on which are mounted the cam disks K, K', and the worm 6 gearing with the
spur wheel C. This spur wheel is keyed to the spindle a, a, and on this spindle is
mounted the cam D, seen in detail Fig. 4; F and F are slide levers provided with
pivots c', c², c³, and c', which are acted on by the aforesaid cam D. To one of these -
slide levers is also fixed a rack g (see Fig. 5), which works into a pinion h mounted
on the spindle or rod f. f. This spindle or rod is supported in suitable brackets,
and to its ends are secured tho throttle valves d, d, in the inlet and outlet air
shoots.,, are the shaking levers which oscillate on the standards H, H, the
latter being pivoted and free to rotate horizontally so as to admit of the free ends
of the shaking levers being brought into contact with the cam disks K and K¹.

page_text: The inlet and outlet shoots are indicated by the direction of the arrows. The
cage or separator, hereinbefore described, is shown by the dotted lines 8, 8, Fig. 3.
The action of the apparatus may be described thus:-The rotation of the driving
shaft B is transmitted to the spindle a, a, on which the cam D in rotating operates
the slide levers F, F, in such a manner that simultaneously these two slide levers
are moved in one direction, so that one of the shaking levers, say ", is thrown into
gear with the cam disk K', while the valves, which communicate with the
compartment underneath said shaking lever, are closed through the operation of
the rack g acting on the pinion h. It will be obvious that while the slide levers
remain in this position the shaking operation of one cage or separator will continue
while the exhaust is carried on freely through the second compartment. Similarly,
by the rotation of the cam D the slide levers are moved in the opposite direction
when a corresponding action takes place. Thus a free and constant suction is
maintained through the apparatus, while the operation of shaking the flannel or
other sifting matorial is accomplished at regular intervals in an easy and effective
manner.
Having thus described the nature of my Invention, and the manner of carrying
same into effect, I would have it understood that what I consider novel and useful,
and therefore claim as the Invention to be secured to me by the hereinbefore in part
recited Letters Patent is,-
First. The construction and arrangement of flour dust separators in the manner
and for the purpose substantially as specified; and,
Second. The combination and arrangement of parts whereby the flour dust
separators are automatically shaken, and also whereby the throttle valves are
_ operated in the inlet and outlet shoots, all for the purpose and in the manner
substantially as liercin described-and-set-forth.
