7 Claims.

This invention relates to an apparatus for the continuous dripping of liquids generally, although more particularly to the continuous dripping of those liquids which tend to coagulate upon exposure to air, such as, liquid paint or dye.

The principal object of this invention is to provide an apparatus for dropping liquid paint or dye onto a stream of broken minerals such as coal, whereby a large portion of said coal will be marked for identification with drops of said liquid paint or dye.

With the above and other objects in view which will more fully appear, the nature of the invention will he more clearly understood by following the description, the appended claims, and the several views illustrated in the accompanying drawings.

In the drawings:

Figure 1 is a front elevation of an apparatus embodying my invention,

Figure 2 is a top plan view thereof,

Figure 3 is a longitudinal vertical section taken on the line 33 of Figure 2,

Figure 4 is an end elevation of the apparatus,

Figure 5 is a vertical section taken on the line 5-5 of Figure 3,

Figure 6 is a detail section of the valve rod assembly showing the valve rod operating arm at the upper limit of oscillation,

Figure 7 is a detail section of the valve rod assembly showing the valve rod operating arm at the lower limit of oscillation, and

Figure 8 is a detail section of the valve rod assembly showing the valve rod operating arm disconnected from the driving means and the,

valve in the seated position.

Like reference numerals designate corresponding parts throughout the several figures of the drawings.

Referring to the drawings in detail, a container 5 having end walls n and i, a front wall 8, a rear wall 9, and a bottom I! ii, is mounted upon a stand i i. The container 5- is preferably mounted over a conveyor which carries broken coal or the like. Within the container is a liquid paint or dye which drips continuously onto the moving coal, thereby marking a large portion of the coal for the purpose of identification. The bottom ii! is provided with a plurality of spaced discharge openings 12 which are disposed in a substantially straight longitudinal line. A plug 13 having a central opening M is screwed upwardly into each opening E2, the upper end of the opening 14 terminating in "a flared valve seat M A horizontal rock shaft I5 is journaled on the end walls 6 and l and is disposed in a vertical plane in parallelism with the openings i2. Rock arms iii are fixed to the rock shaft l5 and the ends of the arms are in vertical alinement with the openings M. A horizontal gide bar I! is rigidly secured within the container to the end walls 6 and l, and is disposed above and in spaced relation to the outlet openings 14, said guide bar being provided with spaced guide openings l8 respectively located above said discharge openings. Valve rods iii are pivotally connected at their ends to the rock arms i6, the rods passing downwardly through the openings H3 in the guide bar ii and thence freely through the openings M in the plugs 53, the lower ends of the rods being located below and in spaced relation to said plugs. A valve 2t having a conical lower end 2! is adjustably mounted on each red I 9 between the guide bar 42 and the associated plug l3 by a set screw 22. A plurality of downwardly extending agitator paddles 23, which are spaced intermediate the rock arms it, are fixed to the rock shaft l5.

Brackets

24, 24 are attached to the rear wall 9 of the container. A drive shaft 25 having a driving pulley 26 is journaled on the brackets 26. Fixed to the drive shaft 25 is a disc 2i which is provided on one face with a concentric series of angularly spaced lugs 28. A two-part rock arm 29 is rigidly fixed to the rock shaft 55 and consists of an inner arm Sll which is fixed to the rock shaft and an outer arm 35 which is pivotally attached to the arm 36 by a pin 32. A. removable pin 33 maintains the two arms 36 and iii in alinement. The outer end of the arm 3! overlies the lugs 28 on the disc 2i.

Upon rotation 01" the disc 21 in a clockwise direction, as viewed in Figs. 6, '2 and 8, the lug in contact with the arm 29 engages the arm, thereby elevating the valve rode it. When the lug moves beyond the end of the arm 22, the arm then gravitates until it contacts the next oncoming lug. This downward movement of the arm 29 effects a rocking of the shaft i5 and a resultant downward movement of the valve rods IS. The arm 29 contacts the next succeeding lug before the valves 2! are seated, thereby always maintaining the valves 29 in spaced relation to the seats i l when the machine is in operation. Continued rotation of the disc causes an intermittent rise and fall of the arm 29, thereby effecting successive reciprocations of the valve rods l9. This reciprocation of the valve rods l9 prevent the liquid within the openings M from coagulating, thereby insuring an even and continuous drip.

It is tobe noted that the lower ends of the valve rods l9 always extend below the plugs I3. Each rod always extends below its associated plug l3 for two reasons: first, to maintain the rod within the opening M of the plug to prevent coagulation of the liquid therein, and secondly to insure an even flow of liquid from the end of said rod.

When it is desired to render the apparatus inoperative, the pin 33 is withdrawn, and the arm 3! is swung upwardly about its pivot 32 until it rests against a stop 3d fixed on the arm 30, thereby disconnecting the rock shaft l5 from the driving shaft 25, the arm 38 then gravitating and causing the shaft if) to rock and thereby effect the lowering of the valves Zil onto their seats I l and preventing further egress of the liquid from the container.

While the invention is herein described as particularly adapted to the use of marking coal or the like, it is to be understood that the invention comprehends broader uses and may be used for dripping glue or paste or other similar materials, all such uses being comprehended within the scope of the appended claims.

It is of course to be understood that the details of structure and arrangement of parts may be variously changed and modified without departing from the spirit and scope of my invention.

I claim:
