SPECIFICATION forming part of Letters Patent No. 736,597, dated August 18, 1903.

Application tiled Janunry', 1903. Serial No. 138.062. (No model.)

.T all whom t may concern:

Be it known that I, CLAUDE D. GROVE, a citizen of the United States, and a resident of Colorado Springs, inthe county of El Paso and State of Colorado, have invented a new and improved Barrel Strainer or Filter, of which the following is a description.

My invention relates to barrel strainers or filters used in straining or filtering solutions of the precious metals obtained in the treatment of ore by chemical processes, such as bromination or chlorination; and it consists of certain novel parts andcombinations of parte particularly pointed out in the claims conclndint,r this specification.

Yin the accompanying drawings I have shown my invention embodied in the form which is at present preferred by me; but it will be understood that various modifications and changes may be made in the structure without departing from the spirit of my 'invention and without exceeding the scope of my claims.

In the accompanying drawings, Figure lis a longitudinal View of a tank or barrel containing a [ilter embodying my invention, the same being partly in section and partly in eievation. Fig. 2 is a top view of a portion ofthe strauenbed. Fig. isasection through 2 on the line 3 3. Fin. 4 is a section through liig. on the line 4i, Fig. 5, isa section through Fig. 2 on the line 5 5.

Similar referencenunierals in the several iignres rerer to the same or corresponding The following is adescription of the structure illustrated in the said drawings.

5 is aeyiiudrical tank or barrel, preferably composed of an iron shell 6 6, interiorly coated with a lead sheath 'I'v 7 to resist the action of the chemicals used therein;

are trunnions adapted to be mounted stmahie journals and to be provided with suitable means for revolving the barrel in the usual way when. charged.

S is a manhole provided with Va suitable cover 1i).

11 is inlet-pipecontrolled bya valve12.

1S is ontletvalve controlled by a valve 14.

`iiithin the barrel andat the bottom thereof is located my improved strainer. In the form shown in the drawings it is composed of a series of lougitudinai planks or strips 15 15 15 15, (although they may be disposed transversely,) mortised at 16 16 .i6 to make a water-tight joint between them. Instead of mortises between the planks gaskets, ofasbes tos or other suitable acid-resisting,r material, may beemployed to maintain a tight joint. These planks are preferably made of wood,

acid-resisting material andfon the sides adjacent to the shell of the barrel rest upon and Vare supported thereby and are preferably made to conform to a greater or less extent with the interior contour thereof or at least to be in contact therewith atasufticient number of points'to afford adequate means of support. On their upper sides they need not be so shaped. The planks 15 are attached to the barrel by means of bolts 1.9, passing through the plan ks and through the outside shell ofthe barrel, by means of which they are securely attached to the shell. The heads of the bolts 19 are provided with caps of some metal or material, such as lead, not acted upon by the chemicals used in the barrel, and suitable washers (not shown) are empl yed to aiord a tight joint to prevent leakage and to prevent the chemicals gaining access to the shaft of the bolt. Each of these planks 15 is perforated bya series of holes or slits 17. These holes or slits maybe in any desired form or arrangement. ln the drawings I have shown them as longitudinal slits; but the)T` might be formed in any other desired direction or the perforations might be made up of holes instead of slits. or slits are made of expanding; area from the interior outwardly, as shown in Fig. 5, inmorder that any solid matter' entering from the barrel may readily pass through and be' discharged from them,thus preventinnclogging.

18 represents transverse channelsregistering with each othernd extending from the outermost perforation 17 inwardly. f

19 is a longitudinal main channel with which the lateral channels 18 communicate.

20 represents grooves formed in the upper surfaces of the outside planks, by means of which fluid which would be retained at the outside edges of the'planks is drained off and Preferably these holes i discharged through the perforations 17 in a manner which will b greadily understood.

'lhc planks may bc treated with any suit- 6o but they may bemade of any other light y manhole 9.

able material or solution to resist the action oi' the chemicals employed. For example, they may be treated `with any tarry, oily, or waxy matter, such as coal-tar, linseed-oil, or paraflin.. For further reducing the chemical action and abrasion on the top of the tilter the planks may be coated with a leadsheath 2l, as shown in Fig. 4. By boring dovetail holes or grooves at the outer surface of the planks and then pouring melted lead or other acid1esistingmetml over the top the planks `.vill be coated with a sheath of metal held in place by lugs which till the dovetail holes or grooves. This sheet of lead is then sawcd through at the slots or punched through at the holes, as will ne readily understood, or staples or similar coutrivances may be driven into the frame and the sheath ot' lead cast around and over them,thus securing the lead.

in operation the ore to be treated having been suitably crushed or pulverized is introduced into the barrel or cylinder through the Water and chemicals are then added. The tank is then revolved asul'ticient time for the chemicals to carry the precious metal into solution, when the motion of the cylinder is arrested with the filter at the bottoni, as shown in Fig. l. rihe solid contents of `the barrel then settle onto the iilter-bed, the largestand heaviest particles settling first on top of the filtering-bed. The holes or slits i7V are small enough to prevent this material passing through them.

The inlet ll now being connected with a waterfsupply under pressure, the cock l2 is opened, as is also the cock ill, the outlet i3 being connected with a discharge-pipe. The process of straining or filtering under pressure then continues in the ordinary way until all the precious metal in solution t. removed from the tankf It will be observed that the solution passing through the'holes or slits v17 gains access to the transverse channels 18 and is by them conducted tothe main longitudinal channel 19, which is connected with the dischargepipe 13 and which channel is of sul't'icient size to carry oli all solution which will pass through the perforations l?. v

The tilter l have described, and illustrated in the drawings, may be cheaply made, is extreme'ly durable, is light in Weight, and does not disturb the balance ottho tank in rotation,

occupies small space, /and in this sense iucreases the capacity'of the barrel, and being securely held in place by bolts is not liable to Work loose or to get out of order during operation. Furthermore, the size of the iilterbed may easily be regulated (enlarged or diminished) to control the rate of filtering by the addition or subtraction of the planks i5.

Having thus described my invent-ion in t-he form which l at present prefer, what l claim, and desirto secure by Letters Patent, is" i. In a barrel-strainer the combinationf. ith the shell thereof,ot` a strainer the exterior .face of which is in contact with the. barret ts body having suitable' straining-perforations and beneath its surface projections integral ,therewith and forming channels commun icating with the discharge-opening, the strainingperforations extending entirely through'said projections.

Lt. in a barrel-strainer the combination with the shell thereof, ofa strainerhavingsuitable straining-perforations and beneath itssnrface projections forming channels communicating with the discharge-opening,the straining-perfoi-ations being of expanding section and extending entirely through'said projections.

5. In a barrel-strainer the combination with the shell thereof, of astrainer composed of a body of wood and a perforated coating of acidresisting metal directly attached thereto by dowels, rivets, or equivalent means.

v 6. In a barrel-strainer the combination with the shell thereof, of astraner composed of a perforated body of wood, and a perforated coating ot' acid-resisting metal directly attached thereto by dowels, rivets or equivalent means, the perforations in the body registering with those in the metal coating.

7. In a barrelstrainer the combination with the shell thereof, of a sheet of acid-resisting metal provided with strainingfperforations, and a support therefor containingsimilar perforations'registering with the perforations in the metal sheet.

S. In a barrel-stiainei-,the combina-tion with the shell thereof, ot' a strainer composed of a name to this specification inv the presence of two subscribing witnesses.
