CENTRIFUGE.
Application led August 31, 1921. `Seria1 No. 497,306.
Be it known that I, ZENO Os'rEuBERG, Ia citizen of the United States, and resldent of San Jose, in the county of Santa Clara and State of California, have-invented certain new and useful Improvements in Centrfuge,
of which the following is a s ecification.
This invention relates to t at type of centrifuge used in the nitration of cotton for commercial purposes.
It is the object of thls inventlon to proi vide a centrifuge of the'character indicated that may be quickly and easily loaded and quickly, and easily-dumped and reset .for loadin without t e great expense of time and la or necessitated by centrifugals as now constructed, and without the risk to life and property presented by their present form.
Figure 1 is a section taken vertlcally through my improved type of centrifuge.'
. Figure 2 is a plan view taken on line 2-2 of Figure 1. y
Figure 3 lis a section through the feed chutes taken on line 3-3 of Figure 1.
.Figure 4 is a section through the hopper cover taken on line 4-4 of Figure 1.
Figure 5 is a section through the water inlet portion taken on line 5-5 of Figure 1.
Figure 6 is an illustration/of another embodiment of my invention, part broken away.
Referring more particularly to the drawing, at 1 is shown a hopper with a discharge outlet2 and an annular water supply passage 3 formed by the inwardly turned upper ed e 4 supplied by pipe 5.'
Ilopper 1 is provided with an exterior flange 6 resting on inner wall 7 of an annular chamber 8 having a discharge outlet at 9, the outer wall 10 of said channel extendingu wardly and forming a seat for cover 11. over 11 is provided with an annular inwardly directed lip 12,- and an outwardly extending flange 13 supporting a head 14, the latter being axially ali ned with the hopper 1. In head 14 is ormed central chute 15 and feed chutes 16-16, the c entral chute 15 broadening out above chutes 16-16 to form a sleeve 17.
Axially arranged in hopper 1, chute 15 and sleeve 17 is a shaft 18 carryin a small annular bowl 19 having a larin si e 20 and a ange. 21 extending outwar ly from the upper edge of said side. Resting on ange 21 is a bowlv top 22 preferably having a perforated flaring side 23 terminating in an outwardl extending flange 24 adapted to \rest on ange 21, and a flaring apron 25. On to 22 are arranged a number of lugs 26 on eac one o f which is pivotally mounted a dog' 27 moving in a vertical plane and welghted above its pivotal point and toward the top 22 as at 28. The dog 27 4 is provided with a -hook 29 adapted to engage the under surface of fiange 21 but normally disengaged therefrom as shown in dotted lines at 30. Top 22 is provided with an opening 31 fitted with a receiving pipe 32 Haring at its upper end 33 to encompass the lower end of chute 15 and adapted to engage lip 12 on cover 11.
At 34 is a member slidably mounted in sleeve 17 and having an arcuate inner and lower surface 35 upon which is arranged a thrust bearing 36, the lower element 37 of which engages surface 35, and the upper element 38 of which is rigidly secured to the upper end of shaft 18. Element 38 is internally geared at 39 to engage gear 40 on an element 41 mounted on driving shaft 42 operating in bearing 43. The ends of shafts 18 and 42 are curved as shown and contactv freely from element 37 as shown in solid lines. Power being applied to shaft 42 the shaft 18 and parts carried thereby are rotated'at the required speed, the centrifugal force generated throwing dogs 27 into engagement with flange 21 and securely locking the bowl 19 and top 22 together. Nitrated cotton being fed in a given quantity through chutes 16-161-15 it falls into bowl 19 and is thrown outwardly therein by the centrifugal force generated by the revolving parts and assumes a position as indicated in dotted lines at 46.
During the spinning of the bowl the excess acids in the nitrated cotton are thrown out through the perforated side 23 of top 22 against cover 11 and collected in channel 8 to be carried away through pipe 9.
When the nitrated cotton is sufficiently wrung the device is stopped and shaft 18 lowered, the dogs V27 automatically disengaging themselves from flange 21 so that the bowl 19 may be lowered to the position shown in dotted lines, the top 22- resting on hopper 1 as shown. The -bowl is now spun again by applying power to shaft 18 thereby throwin all of the material therein outwardly against the walls of hopper 1, where it is taken up by the water flowmg thereover from passage 3 and carried away through the discharge 2.
A moments revolving of bowl 19 havin thoroughly cleaned it it is again raised an filled and the process repeated.
In a centrifuge constructed and operated as above set forth the filling is effected in a short space of time; excess liquid is quickly and effectively removed into a suitable collecting chamber; after wringing, the centrifuge bowl is automatically unlocked, opened and emptied into a separate collecting chamber; the said bowl is quickly and easily reassembled and automatically locked preparatory to refilling.
By connecting and mounting the shafts 18 and 42 as shown a positive drive is ef- -fected between the two shafts and yet the lower` shaft has the necessary flexibility.
Under certain conditions it may be desirable to support bowl 19 from below instead of from above and this can be accomplished without any complexity of parts as shown in Figure 6 of the drawings.
It is to be understood, of course,V that while I have herein shown and described one particular embodiment of my invention, changes in form and constructlon may be made within the scope of the appended claims.
