' vention to the mixing of nitrocellulose with water, for the purpose of-suspending the fibers of the .nitrocellulose in the water, so
4that ,it can be transported through pipes.
It has been diiiicult heretofore to convey certain kinds of nitrocellulose through pipes, even when mixed with water by the bestknown means, as the mixture frequently clogs in tlie pipes owing to imperfect mixing.
,iReferring to the illustrated application of my invention, it is well known that nitrocellulose is made by treating cellulose in an acids bath. `When the chemical reaction is completed, it is necessary to remove the excess acids from the resulting iiitrocellulose. The general practice is to remove as much of the acids as possible by a fluidextracting apparatus and then remove the remainder of the acids' by washing. The common practice is to dump the nitrocellulose vfrom the tluid-extrz'icting apparatus` into a washing' tank. As the addition of small quantities of water to the acid-wet nitrocellulose will cause the nitrocellulose' to decompose, particularly in any lumps in the mass, it is necessary to break up the lumps and mix all the fibers of the nitrocellulose with water as quickly as possible.
. This is done ordinarily by workmen, who
break up thelumps and mix the nitrocellulose with the water by the use of ordinary hand forks. This operation is called drowning. The fumes given olf by this operation are so intense that it is difficult to perform the work proper y-o'r obtain workmen willing'to perform this operatiom Thexfeatures of invention, therefore, which enter into combination with the mixing apparatus, are adapted to prevent the escapeof 'acid fumes, to feed the nitrocel- ,liilseithe required quantities and condition to the mixing device, to mix Athe nitrocellulose thoroughly with the water as quickly as possible (drowning) to preventdecomposition, and to convey the nitrocellulose to the washing device. The apparatus described herein and chosen to illustrate 6o i the invention,therefore, may be described as a combined drowning, mixing, and convcying apparatus.
The object of my invention as applied to the present embodiment thereoffis to convey the nitrocellulose directly from the Huid-extracting apparatus to the Washing apparatus without manual handling and in such a manner as to' prevent the nitrocellulose from decomposing and from diffusing the acid fumes. Other objects of my invention will be apparent 'from the following description, in
' whichf Fwure 1 is a side elevation of a Acombined 7E drowning, mixing, and conveying apparatus with a fluid-extracting apparatus and washing' machine shown diagrammatically in connection therewith;

Similar reference characters refer to similar pants. throughout the drawings.
In the embodiment chosen to illustrate the invention and referring.to Fig. l, reference characters E represent fluid-extracting apparatus `of any desired type, such, for. ex-
the bottoms of the fluid-extracting appara- Vt'us may be removed in any desired manner as by raising, so that the nitrocellulose may be pushed from the sides of the centrifugals directly to the combined drowning and mixing apparatus. A washingr apparatus, such,A
for example, as a washing machine of any desired type is illustrated diagrammatically at the scale being reduced owing to the y ofthe combined 80 drowning, mixing, and conveying apparalimits of the drawing. The centrifugal machines E and washing machine W may be located at any desired place with reference to the combined drowning and mixing,i apparatus, the present drawings 'showing a convenient arrangement for purposes of illustration.
ln the combined drowning and mixing apparatus, ythe nitrocellulose first is received from the .fluid-extracting apparatus in clam shells l, of which two are illustrated in the present embodiment of the invention. These clam .shells when closed forni a chute closed at the top thereby )reventing the escape ot' fumes. Each clamsliellvopens into a chute 2, which leads to a. feeding device or' any desired type. The sides ot the clam shell when closed preferably form part of or a continuation of the walls of the chute, and the walls of the chute preferably increase in horizontal cross-section from top to bottom.
In the present embodiment, a feeding device of any desired type is provided at the bottom of each chute, which is shown herein asa series of bars B, preferably triangular in shape. T hese bars may be rotated in unison by a chain 5 driven from any desired source of power and engaging sprocket wheels et on the bars. These bars 3 are so designed that any predetermined distance may be maintained between them at all times during rotation, and in practice the design is such that very little, it any, of the nitrocellulose ialls between the hars. the feeding device is adapted to move forward only u. comparatively small amount of nitrocellulose even though the entire chute.
be filled with nitrocellulose, the feeding device moving the nitrocellulose at the bottom of the mass adjacent the device, the mass gradually settling until it all has been fed.
rl`he speed of operation of the feeding device' is adjusted to feed just the proper amount to be handled eiectivclj,` by the mixing device. Adjacent the end of each feeding device is u. lump-breaking device of any desired type, which, in the present embodiment, takes the form of a toothed wheel 6 adapted tov take the nitrocellulose from the feedingI device and force it through a vertical rake thereby breaking any lumps in the nitrocellulose. To avoid breakage, the rake 7 is hung loosely, its Weight 'affording suliicient resistance to break any lumps which ordinarily occur.
' From both lump-breaking devices, the nitrocellulose drops through a passage 8 to the mixing device, where the nitrocellulose is mixed thoroughly with water, drowned, and impelled or forced through la pipe 11 to washing machine lV. This thorough mixing together ot the water and nitrocellulose (which is heavier than water) suspends the libere oi. the nitrocellulose in the water so that the mixture flows freely tl'lroug'h the conveyingl pipe or pipes without clogging.
yeraloly is provided with a tra lt will be noted thatQ This also etlectually drowns the nitrocellulose so that there is no danger of its de4 composing. The water preferablyrezwhes the bladcd screw 9 of the mixing device from a passage ls beneath the conveyer, and is 10 supplied. by a pipe 12 (which may be perfo' rated it' desired) at the upper end ofthe passage, so that any particles ot' nitrocellulose. which might fall through the bars are washed to the mixing device. i
The mixing` device in the present embodiment takes the torni ofa screw 9, the blades or' which are pitched at such an angle as to forceuthe nitrocellulose down against the sides ot the howl l() in which it is mounted, 30' which action -chnrns the nitrocellulose and water together so that a .perfect mixture is obtained characterized by the suspension of the individual' fibers in the water. The mixture y is discharged through a pipe 11 preferably g5 leading from near the bottom of the bowl A10 which pipe also preferably is plated taugen?.` tally to said screw 9, When the pipe is lofi., cated near the bottom of the bowl' it pre y outside the 965 bowl as shown in Fig. l, so t at the luidflevel within the Abowl is maintained at de?. sired height' and the I i corrosive, acid .fmesprevented from escaping 'into the pipe and-1 2@ subsequent apparatus. It is obvious that ythe 93 mixing and propelling may be perforn'ied. by V separate devices of similar or of. different-'f types, such, f or eXam'p-le asgtwo separata'. screws or paddles or byva )et or jets of liquid. or gas properly placed and arranged. g
'lhe entire appfratus is inclosed in a casu ing which prevents the escape of acid fumes )1 except through a flue 14 adapted forfthat`f' purpose. -v y Y r'llthough I have illustrated my invention '105 by one embodiment thereof, it is not. tobe limited to such embodiment, which is chosen only for purposes of illustration, my in venu tion consisting of an apparatus for conveying nitrocellulose apparatus to a washing machine without danger of the nitrocellulose decomposing or likelihood ot tlie conveying pipes clogging, the nitrocellulose being fed to the mixing de? vice in required Vquantities andy conditiomfug, drowned and suspended in water, and oreedfi-'- o`r impe-lied through a pipe.
