Specification of Letters Patent.

Yatented ifs-an. 12, 1908*.


To all whom it may concern:

Be it known that 1, JOHN 'l. Witness, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Means for Automatically Controlling Liquid-Suppl and I do declare the following to be a in 1, clear, and exact description of the invention, such as will enable others skilled in the art to which it apertains to make and use the same, reference eing had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to means for auto matically controlling the supply of liquid to a receptacle, being more especially intended for maintaining acid in a trough at a uni form level in canning factories. It is well known that in canning factories, acid must be applied to the cans before the caps are soldered in place.

The object of my invention is to maintain the acid in the trou form level so that t e brush or. other device which is used to apply the acid, shall always enter the. trough or receptacle at a uniform depth; and to this end I provide a source of supply whose discharge extremity enters a recess which is in communication with the acid trough, the said recess being rovided with ribs or beads to prevent the ischarge nozzle of the bottle or-other device from coming in direct contact with the bottom of the recess which might have a tendency to prevent the escape of the liquid. As soon as the liquid rises in the receptacle to a suiiicient depth, to seal the discharge extremity of the supply source, the liquid will cease to flow since no air can enterthe receptacle and consequently the liquid will cease to flow until its level in the trough, is lowered sufiiciently to permit the entrance of air to the supply source in which event, the liquid will begin to flow and continue so to again formed around the discharge opening of the supply source.

Having briefly outlined my'improved construction, I will proceed to describe the same in detail reference being made to the accompanying drawing in which is illustrated an embodiment thereof.

In this drawing, Figure 1 is an elevation partly in-section illustrating In improve ment shown in connection with t e can conh or receptacle at a um-- do until a liquid seal isveyer of a canning factory, the tracl: of the conveyer being shown in cross Fig. 2 1s a top plan view oi the same,

th s:

a top view in detail oi the acid trough er receptacle.

The same reference characters indicate the same parts in all the view e.

Let the numeral 5 designate a vertical rod connected by means of. a set bolt 6 with a stationary bracket 7 connected'with a tract: 8 supporting a chain 9 engaging cans l0 whereby the latter are caused to move along the track to the desired location. Tethe upright rod 5, is secured an acid trough '12 ads ted to contain a quantity of liquid 13, the ody of the trough. being in coinn-antiication with a recess l of ribs 15 upon which the nozzle 15 oi a bottle 17 rests. This bottle is chosen as a convert tional acid-containing device. in the con structicn shown in the drawing the bottle 'is inverted and its open ne *k or nozzle is in serted in the recess 14 and rests upon radialiy disposed ribs or projections 15, whereby the liquid is allowed to flow freely from the bottle until the trough is filled and the liquid rises in the recess. 14; to a suiiieient level to seal the nozzle of the bottle.

The trough 12 is rovided. with apertured projection 18 t rough which passes the place many desired position by means of a set bolt 19.

It will be understood that the acid trough and the source of supply connected therewith ma be raised and lowered with refer ence to tlie track 8, by loosening the set bolt 6 and moving the rod 5 either up or down in the eye 4 of the bracket 7. B virtue of this adjustment the position of t ie trough and source of supply may be accurately regulated it ith reference to the height of the can top to which the acid is to be applied.

The bottle 17 containing a quantity of acid may be supported in the inverted vertical position by means of curved arms 20 and 21, each of which is connected at one err" tremity with a sleeve 22 slidable on the rod 5 and held in the desired position of adjust ment by a set bolt 23. Thesearins pass part way around the bottle in opposite di rections from the sleeve. The arm 21 is provided with an inwardly projecting lug 24: adapted to engage the bottle 17. The arm 20 is provided at its free extremity with a section.

veyer mechanism being omitted. a

rod 5, the receptacle being maintained in inc threaded. o ening in which is inserted a set screw w hich-may be screwed to engagement with the bottle. The sleeve 22, is also provided with an inwardl projecting lug 26 adapted to engage the ottle. The two arms 20 and 21 taken together pass more than half Way around the bottle and when the set screw is properly adjusted, the bottle is securely supported in the'inverted vertical position.

From the foregoing. description the use and operation of my improved device will be readily understood. Assuming that the acid trough and the bottle-sup orting device are properly adjusted upon the rod 5 and that the latter is properly adjusted with reference v to the tops of the cans carried by the' conaround the discharge nozzle of t other source of supply, will cease to flow until veyer, the operation is as follows: The liquid first flows freely from the open nozzle of the bottle 17 into the recess 14 and thence into the acid trough or receptacle 12 until the latter is filled and the liquid rises in the recess 14 to aheight sufficient to seal the 0 ening of the nozzle 16 from the entrance of air. The liquid will then cease to flow until it has been lowered in the trough or rece tacle sufficientl allow the air to enter the ottle and brealz the recess and thence into the trough or receptacle 12 until a liquid seal is a sin formed e bottle or after which the li uid it is again lowere in the trough after which the operation is automatically repeated.

Having thus described my invention, what I claim is: 1. In apparatus of the class described, the combination with a stationary support, of a supporting rod vertically adjustable on. said support, a liquid-containing trough mounted on the support and having a recess located beyond the body of the trough but in communication therewith, a liquid-containing receptacle having its discharge extremity to, the vacuum above the liquid.v The latter will then continue to flow into scenes entering the said recess in position to allow the liquid to flow from the receptacle into the said recess, means for maintaining the liquid-containing receptacle in the position of discharge whereby the liquid will flow therefrom into the recess until the liquid rises in the trough sufliciently to seal the discharge extremity of the liquid-containing receptacle, substantially as described.

2. The combination with a stationary support, of a vertically disposed rod mounted on said support, an acid trough attached to the support and vertically'adjustable thereon, a liquid-containingreceptacle having its discharge extremity projecting into the trough, whereby the liquid is allowed to flow into the trough until it rises sufiiciently to seal the discharge extremity of the source of supply, and arms mounted onthesupporting ro and embracing the liquid-containing receptacle for maintaining the latter in position of dischar e with reference to said trough, substantia ly as described.

3. The combination with a stationary member, of a vertically'disposed supporting rod attached to the said stationar member, an acid trough vertically adjusta Is on the said rod, a supply source having a discharge nozzle rojecting into ,the trough, and arms vertica y adjustable upon the supporting rod and embracing the source of supply whereby the latter is maintained in the CS1- tion of discharge, substantially as descri ed.

4. The combination with. a conveyer track, of an acid trough connected therewith and arranged at one side thereof, a supply source having a discharge nozzle projecting into the trough, and arms for supporting the supply source in the discharge position, substane tially as described.

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

A. J. OBRIEN, DENA Nansen.
