beardt of the flume in fig 7 is shown a modification of the before mentioned binder frames in this thia construction st the binders are not canted but the same eff effect act is produced by means of the key or wedge 7 acting against 11 the ta tapered p ered side 4 of the binder frame and one side aide of the flume in figs 1 2 3 efa IX 4 5 and 6 a are r e shown binders e consisting 0 n s i s t i n of a L skeleton f frame r a in e w which bich loosely embraces the exterior of the flume when in a vertical position as shown at figs 1 2 and 6 but when canted as shown at figs 3 4 and 5 the top and bottom rails 2 and 3 will crowd 11 J ll L against the top lop and floor of the flume under this ri pressure the beveled edres edges la of such top and bottom acting against yiu arf the corresponding

mortar or tank is a stamp or muller 9 which is convex on its bottom and rigidly t attached to its to top p is a pitman 10 which extends upward through the opening 0 6 and connects with a crank 11 to which ill motion 0 may be imparted by uny ny suitable means this crank is shown in the form of a disk and the wrist pin 12 for the pitman 10 is adjustable in a slot 13 formed in the disk so that the throw of the stamp or muller may be regulated it is obvious tamm my the opt operation op bration ration of the crank I 1 11 I 1 tile stamp y muller will be reciprocated longitudinally in the mortar and it will also have a sliding motion so that ay as it approaches pro aches tile the end of the mortar the stamp or mortar will be so tilted as to leave a space between its bottom and the ore on which it is operating so that the ore may be washed underneath the alie same by the water placed in the mortar or tank with the ore the metal crushed crus lied and washed out of tile the ore will bo be gathered fathered Va in the mercury box with the mercury the ore may be passed through the opening 6 or it may be placed in the mortar before the boxing is placed thereon the water will flow continuously into the mortar through h a suitable pipe 14 and the waste or light portions will pass out through the sieves 15 at the ends of the mortar |
