JEROME HAVERLY, OF LOS ANGELES, CALIFORNIA.

MERCURY-SEPARATOR.

Specification of Letters Patent.

Patented July 11, 1916.

Application filed Novembcr.15, 1915'. Serial No. 61,602.

7 '0 all whom it may concern Be it known that I, JEROME I'IAVERLY, a citizen of the United States, residing at Los Angeles, in the .county of Los Angeles and State of California, have invented certain new and useful Improvements in Mercury- Separators, of which the following 1s a specification, reference being had to the accompanying drawings.

This invention relates to certain lmprovements in mercury separators; and it is an object of the invention to provide a novel and improved device of this general character especially designed and adapted to be employed in connection with the waste or tailings resulting from a prior passage of auriferous material so that a saving of the mercury and gold contained in the waste or tailings may be effected.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved mercury separatorv whereby certam important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully'set forth.

The novel features of the invention will be-carefully defined in the appended claims.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view in side elevation, with parts in section, of a mercury separator constructed in accordance with an embodiment of my invention, the adjacent portion of the coacting mercury well of an amalgamator being indicated by dotted lines; Fig. 2 1s a longitudinal vertical sectional View taken through the device as disclosed in Fig. 1, with the coacting well also indicated by dotted lines; Fig. 3 is a view in top plane of the device as herein embodied; and Fig. 4

is a sectional view taken substantially on the line 4-4 of Fig. 1.

As disclosed in the accompanying drawings, W denotes the discharge end of a mercury well of an amalgamator preferably of a type embodied in the patent of Elmer W. Hoffman, No. 1,150,191, dated August 17 1915, and having secured thereto the lower extremities of the side flanges l of the bed B, the connection between the bed and well being preferably afforded by the overlapping-ears 2 through which pass the pins 3. The bed B is preferably disposed on an incline of about thirty degrees and positioned upon said bed is the shaker S also provided with the longitudinally disposed upstanding flanges 4 and of a width less than the width of the bed B. The shaker S rests upon the antifriction members 5, preferably spherical bodies arranged within the grooves 6 formed in the upper face of the bed B and disposed transversely thereto whereby said shaker may be reciprocated transversely of the bed with a minimum of friction.

Depending from the shaker S and extending through the transversely disposed slots 7 in the bed B are the bearings 8 in which are mounted the extremities of the shaft or rod 9. Operatively engaged with the shaft or rod 9 are the pitmen 10 extending beyond a longitudinal margin of the bed B and having their outer extremities operatively engaged with the eccentrics 11 carried by the shaft 12 whereby it will be perceived that upon axial rotation being imparted to the shaft 12, the shaker S will be caused to reciprocate transversely of the bed B. As herein embodied, the shaft 12 is rotatably supported in the bearings 14 fixed to the bed B and having one extremity operatively engaged, as at 15, with a suitable source of power.

The flanges 1 of the bed B are provided with the transversely alined and longitudinally spaced openings 16 defined by the outstanding flanges 17 whereby guide-ways are afforded for the bearing blocks 18. Mounted within the blocks 18 for rotary movement are the extremities of the shafts 20 which 'also extend through the flanges 4 of the shaker S. The intermediate portions of the shaft 20 are square in cross section and the faces of the squared portions of the shafts have secured thereto the blades 21. The blades are of a length less than the width of the shaker and of such a width as to closely approach the bottom of the shaker S when the shafts are rotated but affording sufficient space, preferably three-eighths of an inch, to afford an unobstructed flow over the bottom of the shaker.

Extending upwardly from the bottom of the shaker and between each of the shafts 20. is a transversely disposed series of teeth or pins 22 which serve as agitators and which are of such a height as tov permit the blades lift said waste or tailings upwardly and throw the same upon the blades of the succeeding shaft and so on until the waste or tailings is discharged at the upper end of the bed. During this lifting coaction of the waste or tailings in connection with the agitation afforded by the pins 22 to the waste or tailings which drops upon the bed of the' shaker, it will be perceived that the mercury which may be carried out of the well W with the waste or tailings will be separated therefrom and drained back into the well V whereby the possibility of loss of mercury together with the gold is substantially entirely eliminated.

It is to be noted that coacting with the upper and lower faces of the blocks 18 are the adjusting members 23'herein disclosed as bolts threaded through the upper and lower flanges 17. Bythis arrangement, it will be perceived that the blades 21 may be adjusted relative to the bottom of the shaker S as the requirements of practice necessitates. It is also to be observed that the shafts 20'are arranged within the open slots 24Eproduced in the flanges 4 of the shaker S so'that no obstruction will be afforded to the adjustment of said shafts relative to the bottom of the shaker.

From the foregoing description, it is thought to be obvious that amercury well constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particu larly: well adapted for use by reason of the convenience and facility with which it may be assembled, and it' will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for thisrea'sonI do not Wish to be understood as limiting myself to the precis'e arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

1. A mercury separator including a longitudinally inclined receptacle provided with feed supply means at its lower end, means for transversely reciprocating said receptacle, a plurality of rotary members transversely arranged in series along said receptacle, each provided with lifting blades, the lifting blades of one member being adapted to deliver material into the field of operation of the next higher rotary member, and said blades being spaced from the bottom of said receptacle at their points of nearest approach.

2. A mercury separator including a longitudinally inclined receptacle provided with feed supply means at its lower end, means for transversely reciprocating said receptacle, a plurality of rotary members transversely arranged in series along said receptacle, each provided with lifting blades, the lifting blades of one member being adapted to deliver material into the field of operation of the next higher rotary member, said blades being spaced from the bottom of said receptacle at their points of nearest approach, and a series of upstanding pins on the bottom of the receptacle intermediate adjacent rotary members.

3. A mercury separator including a longitudinally inclined receptacle provided with feed supply means at its lower end, means for transversely reciprocating said receptacle, a plurality of rotary members transversely arranged in series along said receptacle, each provided with lifting blades, the lifting blades of one member being adapted to deliver material into the field of operation of the next higher rotary member, said blades being spaced from the bottom of said receptacle at their points of nearest approach, and said rotary members being supported independently of the receptacle whereby said rotary members are mounted for rotary but not reeipro'catory movement.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.

H. Bmvrnn, FRANK lVA'rnRrIELD.
