Serial No. 724,464.

To all whom it may concern Be it known that I, EDWARD O. C. Ono, captain, U. S. Army, 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 Miners Gold-Pans; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in miners gold pans, especially adapted for placer washing, and it consists in the constructions, combinations and arrangements herein described and claimed.

An object of my invention is to provide an improved gold pan having means for panning the dirt to concentrate the rich metallic particles, and independent means for vanning the concentrated clean-up material of said panning means.

A further object of my invention is to provide an improved gold pan having a shallow spout recessed in its peripheral wall, and provided with means for enabling the pan to be given a combined tilting and rotary motion about a fixed point in the central vertical plane of said spout, for eliiciently separating the metallic particles from the lighter gangue with less loss than has been heretofore possible.

A further object of my invention is to provide an improved gold pan having a maximum capacity, and in which large quantities of material can be more eflicient-ly treated than in existing constructions.

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views Figure 1 is a top view of a gold pan, illustrating one embodiment of my invention; Fig. 2 is a section on the line 22 of Fig. 1; and Fig. 3 is a fragmentary section, showing a modified construction; Fig. 4 is a top plan view, illustrating a modified construction; and Fig. 5 is a section on the line 55 of Fig. 4.

Referring to the drawings, 1 indicates the base of a pan provided with an upwardly flaring peripheral wall 2 and with a central bottom boss having an upwardly converging peripheral wall 3, which cooperates with the flaring wall 2 to provide a downwardly converging narrow annular way for the material. The pan is provided with a wide and relatively shallow spout 4 inclined outwardly from the bottom thereof and constituting throughout its length a continuation of the pan wall 2. The spout 4 is shown having a bottom 5 depressed, or otherwise shaped, to provide a recess or trap for retaining the heavy gold particles, but said spout may be flared upwardly from the edge of the pan base 1 if desired, as shown in Fig. 4.

A bail 6 is pivoted within the side walls of the spout 4 for cooperation with a diametrically-opposite bail 7 pivoted to, the pan wall 2, to operate the pan. This provides a highly advantageous construction, in which the bail 6 can be held substantially stationary by the left hand of an operator,

I and the bail 7 conveniently operated by the right hand to give a combined tilting and rotary motion to the pan about a fixed point in the central vertical plane of the spout 4; thereby enabling the lighter gangue and waste to be quickly and efficiently washed over the edge of the spout 4 with less loss of the rich metallic sands than has been possible in previous constructions.

In order to permit large and heavy quantities of material to be quickly and conveniently treated, the pan is preferably submerged, and is constructed to be suspended by ropes attached to a central bend 8 of the bail 6 and to peripheral openings 9 spaced equally 011 opposite sides of a diametrical plane extending through said suspension bend 8; thereby insuring efiicient treatment of large quantities of material by an even motion, and with a minimum of effort. I

The pan base 1 is shown provided with a recess 11 cooperating with the trap 5 for entrapping the heavy metallic particles, and quick silver may be placed in said traps 5 and 11 to aid in the recovery of the gold. If desired, an amalgam plate, such as shown in Fig. 5, may be inserted in the shallow spout 4 for recovering any very light particles of gold therein.

The top of the central bottom boss is provided with a concave, or conical, top 12, to constitute a vanner for the final cleanup material taken from the spout 4; said vanner enabling a more complete and effective separation of the gold than is possible in the pan proper. The vanner 12 may be provided with a central trap 13, which is preferably filled with quick silver for amalgamating with the gold. After panning, the clean-up material can be quickly removed from the pan and deposited on the concave top 12 of the central boss and vanned to effect a more complete separation of the gold.

Fig. 3 illustrates a slightly modified construction, in which the bottom of the shallow spout 4 is provided with a trap 14 of rectangular cross section for retaining the heavier metallic particles, and the trap 13 is omitted from the vanner 12.

Figs. 4 and 5 illustrate a modified construction, in which the wide shallow spout flares upwardly directly from the edge of the base 1 of the pan. I have shown an amalgam plate 14 placed in the spout to prevent the escape of fine gold particles.

I have illustrated and described preferred and satisfactory constructions, but changes could be made within the spirit and scope of my invention.

I claim 1. A gold pan provided with an inclined spout constituting a shallow pocket in its peripheral wall, and a central bottom boss formed with a concave top.

2. A gold pan provided with an inclined spout constituting a shallow pocket in its peripheral wall, and a central bottom boss formed with a concave top provided with a central recess or trap.

3. A gold pan provided with an inclined spout constituting a shallow pocket in its peripheral wall and formed with a bottom recess or trap, a central bottom boss formed with a concave top, and means for suspending the pan for swing about a fixed point in the central vertical plane of said spout.

4. A gold pan having an upwardly flaring peripheral wall provided with a spout constituting a shallow pocket, and a central bottom boss having an upwardly converging peripheral wall and a concave top.

In testimony whereof, I afiix my signature, in presence of two witnesses.
