' To all whom it may concern:
Be it known that We,CHEsTER J UBJA'NDALL, a citizen of the United States, resldin at Naugatuck, county of'New Haven, and State of Connecticut, and ICHARD R. TAYLOR, a citizen of the United States, residing at Naugatuck, county-of New Haven, and State of Connecticut, have invented certain new and. useful Improvements in Apparatus for Compacting Pulverulent Material, of which the following is a I'ulLclear, and exact de scription. v
This invention relates to apparatus for compacting pulverulent particles, more spe- .cifically for compacting carbon particles.
. in manufacturing processes. It has further as an object the prov'isionof a simple and efficient apparatus for this purpose,
The invention accordingly consists 1n an apparatus'for solidifying pulverulent aterial comprising achamber, a closure t ere for, a flexible impervious receptacle or bag disposed in said chamber, means for exhausting air from thebag, and means for admittingifiuid under pressure against the out- 'In the drawing the figure illustrates a transverse sectional elevation of a preferred form of apparatus. v y
In said figure the chamber 1 which may be of any desired form is provided with a closure 2 which is adapted to be bolted thereto, gaskets 3 being provided to secure a hermetic sealing. At any desired location on the wall of the chamber is provided an annular flange 9 and an annular ring or clamping'device 10 is adapted to fit into the recess above said flange. A flexible impervious receptacle such as a rubber bag 8 has its edges inserted between the flange 9 and the ring 10 and is securely clamped therebetween by means of screws as shown. The bag 8 may be provided with folds 8 as shown in order to provide ample capacity for stretching and distortion while in'use.
There is thus formed between the walls of l the. chamber 1 and the bag 8 an annular air space 11. A pipe '12 provided with valve 13 leads to the space on one side of the bag as shown, and the other end of the pipe is'connected to a vacuum pump or other evacuating device, a valve 14 being provided for opening and closing the vacuum line. pipe 15 provided with valve 16 leads through the wall of the chamber 1 to the space 11, and this pipe leads at its other end, to a compressor such as an air compressor, a valve 17 being provided for turning on and-ofi' the air or fluid supply.- Between pipes 12 and 15 is a pipe 19 provided with valve 18 for communication. A pipe'l conducts liquid from the chamber, in case liquid is used for compression.
In theioperation of this apparatus, the container or bag 5 constructed to permit the passage of air therefrom and containing pulverulent material such as carbon black is placed inside a bag 8 and the cover 2 is clamped to the chamber. Air is exhausted through pipe12 from the inside of the ba 8 whereby the air residin in and attached to the pulverulent particles escapes through the bag 5 and passes out through pipe 12, valves 13 and 14 being open. While the air is being exhausted from the interior of the bag 5, the air in space 11 shouldalso be exhausted through pipes 15 and 19, valves 16 and 18 being open and 17 closed. After the air has been exhausted. fluid under pressure is admitted through pipe 15, valve 18 being closed, to the outside of the bag 8 which is accordingly compressed around the bag 5 and thereby compacts the pulverulent material to a much reduced bulk. Any suflicient pressure may of course be used but in practice a pressure of approximately 40 lbs. per s uare inch for a period of five minutes. is desirable. A slightly greater compaction may be secured at this point by-simultaneously evacuating land compressing, the valve 18 being closed.
After-the pulverulent material is reduced in bulk by this operation, the closure 2 is removed and the bag 5 withdrawn.
While, the material of the bag 8 -is pref-.
erably rubber, it may also be of leather, cloth, canvas or thin metal, such as tin, and it need not be in the form of a bag,
for it may be of any other shape as longas it stretches across the chamber so as to form a receptacle adapted to contain the sack 5. The receptacle or bag need not necessarily be attached to the wall of the-chamber for it'may be clamped between the cover 2' and the chamber 1 or it maybe suitably attached to the cower 2 so as to be withdrawn when the cover is removed, the pipe 12 communicatmg in th1s case-through the cover and the cover being provided wlth means for access to the interior @f the bag.
It will be clear that this apparatus is V simple and efficient and that itiscapable of what we claim and desire to protect by Letters Patent is:
1. In apparatus for solidifying pulverulent material, a chamber, a closure therefor, a flexible impervious" receptacle disposed in said chamber and having its edges clamped to the walls of said chamber, means for exhausting air from the receptacle and means for admitting fluidun'der pressure to the outside of said receptacle.
2. In apparatus for solidifying pulverulent material, a chamber, a closure therefor, a rubber bag disposed in said chamber having its edges clamped to the walls of said chamber, means for exhausting air from the bag, and means for admitting fluid under pressure against the outside walls of the bag.
3. In apparatus for solidifying pulvcrulent material, a chamber, aclosure therefor, a rubber'bag disposed in said chamber having' its edges clamped to the walls of said chamber, said bag having sufficient surface area to allow for distortion while in use. means for exhausting air from the bag, and means for admitting fluid under pressure against the outside of the'bag.
sighed at Naugatuck, county of New Haven, State of'Connecticut, this 16th day of June, 1920.
CHESTER J. RANDALL.
