The upper casting B of the agitation vessel D is strengthened by braces 27 and 2S which are cast integral therewith. Liner plates 29, are bolted or otherwise secured t0 the braces 28 on the side thereof againstl which the pulp is thrown ly the agitator. ,In the present instance the agitator is designed to revolve in the direction indicated by .the arrow in llig. The braces and liner plates 2% perform the additional function of iineventing the. pulp, which is thrown upwardly and nuwardluv b v the agitator, from escaping through the air inlet pipes 30, which extend upwardly from openings in the top l-l of the agitation vessel, the upwardly extending pipes themselves forming an additional safeguard against escape of pulp. Upon the upper ends of the pipes 30 are valve casings 31, provided with valves 33 to regulate the admission of air, and with deflector plates 3:2 extending across the axes of the cas-ings 8l to arrest any pulp that might be thrown upwardly in the pipes 30. The circular movement ot the pulp as it is thrown upwardly is arrested by the plates 29, thus causing the pulp to fall into the launder formed outside of the liner 17 by the upper part of the liner, the outwardly' extending floor l2 and the vertical wall 13.

The spitz box or separating box C is placed opposite and adjacent the agitation vessel D and is of the usual. tapering form at its lower end. The Side Al() of the separating box adjoining the agitation vessel is provided with an opcnii E20', registering with the opening Q0 in the enlarged part 13 of the agitation vessel, and a sliding valve or gate 4l is provided for regulating the opening E20-202 The gate 41 is suspended on screw-threaded rods 42 in engagement with screw-threaded adjusting Wheels 43 which rest upon vsum'iorts at the upper edge of the Wall ot' the box.

Extending upwardly and outwardly from a point. below the opening 20H20 I provide a guide plate 4o ,lesig'ned to give an up- .Ward direction to the pulp issuing from the opening 20- -20.

The box (l is provided with an adiustable overflow gate 4G. Extending upwardly from the bottom of the separating box C a partition or baille 4H. the upper edge of the .same being located about midway between the bottom of'i'the box and the water level therein as determined by the overflow gate 46.

Pulp enters and leaves the apparatus through inlet and outlet openings 5() and Li9, in the sides of the separating box, but is prevented by the baffle 48 Vfrom passing through the separating box without traversing the agitation vessel. Extending vtrom the lower part of the separating box are two circulation pipes or duct-'s GO, (5l, one on each side of the baille l-F. '.`hese pipes G0. (il extend upwardly to the side ol the box next the agitation vessel. where they communicate through ports in the side ot' the box, with the ducts lr, 15), extending outwardly from the lower part of the agitation vessel. The openings in the lower ein g-z ot' the pipes (3U. ($1, are controlled by v..lvo,. ($2, (Sil. which have arins pivotcd to said pipes as indicated at (il and "i5 aniFhavc az arcuate movement across the ends thereof.

The baille 48, is provided with an opening 72 at the lower part ot' the separating box,iwhich opening is normally closed by a valve T3, when the apparatus is in operation, the valve T3 being opened only when one unit of a series is to be put out ot operation without disturbing the operation ol' the other members or units of the series.

lVater supply pipes 74, having their ends directed into the ends of the pipes 6() and 61.

are provided for the purpose of flushing the apparatus in case it gets clogged through settlement ol' tlu` pulp.

In operation the apparatus may be used either in single units or in series as diagramlnatically illustrated in Fig. 4. In operation the apparatus is first started with water, orc pulp not being admitted until alter the apparatus is started with water. ln this 'way all .liability is avoided of clogging the apparatus by settlement ot' the ore, which might occur if pulp were admitted before a current was established through the apparatus. In starting a single unit ot' the apparatus, the outlet valve l) ot' the separating,r lov is closed and the inlet and circulation valves opened. As soon as the apparatus fills with water to a height sulicient to sulnnerge the lower agitator 23, the agitator commences to agitato and torce the water upward in the agitation vessel I), and to throw it through tlul opening at the top lhereol', whence it flows through the' duct 20--20 to the Aseparating box A higher ellectivc lcvcl or hydraulic head is thus established in the separatinj r box and the water begins to flow back to the agitation vessel D through the ducts (i0, ($1v` thusl establishing the local circulation. '.l`hcrcupon the outlet Ll) is opened, and pulp instead of watcr is admitted through thc inlet .70. .If several units are to be operated in series as diagrammaticaily illustrated in Fig. l. the .several units are preferably arranged upon an incline, the pulp entering the highest unit and dischargingr from the lowest. ln Fig. Inl 1 have shown the bottom of thc separating box inclimng downward from the inlet to or primed da, discharge side, and this inclination conifiuuous in a series of machines, the bot tom Si() cxti'ndingj under all ot the separating boxes at the (sauve inclination arf We dif? Y wat boxes beim! separated irma h osi r by vcrticai vvaiis 9i. The extent oi local lulation imparted to thiZ pulp in each iii unit of the apparatus may be regulated iluouggll i Aimant oi the vaines and speed of the i raton tho circulation being brought aoout liv the tact that pulp is dis charged upward from the agitation vesseis into the spitz box at a more rapid rato than il' is supplied to and discharge from the apparatus through the inlet .30 and outlet l). The ballies or partitions in prevent the heavy and coarse material or any partoi the pulp from passing directly through the separating box without entering the agitation vessel and thus insure 'irculation. I provide an opening 7:. in the iialile or partition do, but this opening is closed in the operation of the apparatus l.' a valve '(3. ln case howcver it is necessary to stop the ol'ieratioo. of any one unit of a series vfor repairs or other purpose, this may be donc without interrupiingr the operation of the other members of the series, it being necessary merely to open the valve T3 in the partition or baiile, thus permitting the pulp to iow directly' through the separating box (l oi the disabled unit, `without traversing the agitation vessel thereof` 4in operation it may bc found advantageous lo adjust the gate il controlling the port i142-Y :'l' leading to the separating box ironi inc agitation vessel with the lower edge of the gate beneath the liquid level. ln fh event air cannot liovv into the agit# fion v Lsel through the port.
