Letters Patent No. 111,669, dated February 7, 1871.-

IMPROVE'MENT IN FEEDING QUICKSILVER TO STAMPS AND AMALGANIATORS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern had to the accompanying drawing, forming a part otithis specification, and to -the letters of reference marked thereon.

My invention has for its object to provide au apparatus for feeding quicksilver to stamp-mills and amalgamators, which may bc readily adj usted` so as to supply a larger or smaller quantity of quicksilver,

as may be desired, to the mill or amalgamator, and

by means of which the quantity so. fed or supplied may be accurately measured and determined.

Hitherto, the usual mode employed has been to throw in byvhand a small quantity of Quicksilver at certain intervals; but it is evident that by such means the quantity fed would be irregular, even with the greatest care.

' By my invention, however, the quantity supplied can be regulated with the greatest nicety and precision.

This invention is also well adaptedfor supplying oil to `machinery for lubricating purposes.

The nature of my invention consists in the employment or use of a cup provided atvits lower extremity with a hollow stem, throughwhich the Quicksilver is conducted into the Astampo'r amalgamator.

W'ithin the said stem is fitted and works a horizontal tapering shaft,V having an equal bearing through the said stem, which said shaft is provided with one or more longitudinal slots, within each of which said slots is vfitted a sliding plug, operated by a set-screw located and workingwithiu the shaft.

Secured to the outer end'ot1 this shaft is a pulley, by which the shaft is operated, and, the shaft rotates, the slots already mentioned receive a charge of quicksilver vfrom the cup, and delivenit into the opening in the stem, from whence it passes into the stamp or amalgamator, the size of the charge being regulated at will by means ofthe set-screw above mentioned.

To enable others skilled in the art to make and use my invention, I will proceed more particularly to describe its construction and operation.

Figure 1 is a top plan View of my apparatus.

Figure 2 is a vertical section, taken through the 'line X X.

Figure 3 is a transverse section of the shaft to show the position of the sliding plugs,

Letters of like name and kind indicate like parts in each of the gures.

A represents the cup, which 'may he .made of any proper material and of suitable dimensions, Aand is provided at its'lower extremity with a hollow stem, B, thrpugh which the QuicksilverV is conducted from the cup A to the amalgamator.

'lhe lower end of l this stem is fitted into the shell or -covering ofthe amalgamator ron which it is to be used, either by meansof' a screw-thread, as seen at a, or by any other suitable and well-known means.

Within the stem B is closely fitted a horizontal tapering `shaft, C, which has an equal bearing through the said stem, and 4is made to rotate therein by means of'a pulley, D, attached and secured to its outer end.

The shaft C is provided with one ormore longitudinal slots, which, as the shaft rotates, receive the quicksilver from the cup A, and depositit within the hollow stem B, from whence it passes into the'amalgamator.

Within each of these slots is fitted a sliding plug, b, for the purpose of regulating the quantity or size of the charge o'f quicksilver received from the cup and deposited A.within the amalgamator.

Each 'ofthe said plugs is provided vwith a gib, c, that iits and works in an annular groove on a shaft attached to a setscrew, E, located and workingwithin the shaft, by which means the said plugs are made adjustable, -so that the quantity of quicksilver receivedinto the slots at each charge may be increased or diminished as may be desired.

One of `these plugs is made longer than the others, and extends outside of the stem, so that its end comes opposite to ascale,'f, marked upon the shaft,

by which means the quantity of Quicksilver received not require particular description.

It ,will be understood that the pulley D may be either turned by hand or. driven by a belt, as may be desired.

The operation is simple and readily understood.

Vhen the shaft G is made to rotate, each ot: the slots in'its turn comes directly underneath the opening iu the bottom of the cup' A, and receives its ch. rge, which it deposits in thehollow stem B, from whence it passes into the amalgamator, the quantity or size ofthe charge being regulated by means of the sliding plugs fitted in the slots on the shaft, which said plugs are adjusted by means of the'set-screw E,

' so that the recess will hold just the quantity wanted;

and, the shaft being closely fitted within the stem,

. the charge of quicksilver "received Vfrom the cup into the recess is 'cut oix and retained in the latter, until, by the rotation of theshaft, it is brought to the open space in the lower part Iof thestem, when it falls out and passes into the amalgalnalgor.

Having thus described my invention,

What'I claim as new, and desire to secure by ters Patent 0f the United States, is-

1. The adjustable plugs b, operated by means o f `a set-screw, and constructed and arranged in connection With the shaft O and cup or reservoir A, to cut olf Lei- and deliver to the stamp-mill or amalgamator any desired quantity of' quieks'ilver, substantially as herein ,shown and described.

2; In combination with the plugs b and shaft C, the scale or indicatorj, substantially as described, and for the purposes set forth.

GEORGE G. MUNSON.
