OIL-FEEDER.

Specification of Letters Patent.

Patented Nov. 16, 1920.

1 '0 all whom it may concern:

Be it known that I, MAX KRAUT, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Oil-Feeders, of which the following is a specification.

. My invention relates to oil or other liquid feeders, and is particularly adapted for use in connection with mineral flotation processes todeliver all kinds of liquid reagents, such as vegetable and mineral oils, acids, alkalis, and sodium sulfids, to ore grinding machines or directly to flotation apparatus.

The object of my invention is to provide a means for feeding oil or other liquids regularly and uniformly.

Another object i to provide a device whereby oil or other liquids may be delivered intermittently to any desired receptacle in measured quantities.

A further object of my invention is to provide a device which may be readily adjusted, whereby a predetermined quantlty of oil or other liquids may be delivered at predetermined intervals.

A still further object of my invention is to provide a device which will be simple and durable in construction and efficient in operation.

Other objects will appear in the detailed description of my device.

' Referring to the accompanying drawings,

Figure 1 is a side elevation of my device, parts being broken away and shown in section in order to illustrate more clearly the details of construction.

Fig. 2 is an end view of the same.

Fig. 3 is a sectional view showing one end of the disk shaft and the means for adjustin the tripping member.

I ig. 4 is a section taken on line 44 of Fi 1.

ig. 5 is a detail view of one end of one of the lever members.

In carrying out my invention, 10 represents a reservoir of any suitable material, preferably rectangular in shape, adapted to hold oil or other liquids, having the bottom 11, thesides 12 and 13, and the

ends

14 and 15.

Bearings

16 and 17 are secured to the side walls12 and 13 in which is journaled the transverse shaft 18 having keyed thereto the annular disk 19 arranged approximately midway between the

walls

12 and 13, and

adapted to project into the tank 10. Se-

cured to the end of shaft 18 is the pulley 2O adapted to be driven at any suitable speed by means of a belt connection to a source of power (not shown).'

Secured to the wall 15 of the reservoir 10 is the guideway 22 in which is adapted to slide the block 23 carrying the gage'blade 24. A stem 27 provided with the hand wheel 25 is journaled in the bearing 26 and is threaded on its free end to engage with a threaded aperture in the nut. 23. By this arrangement it will be seen that the gage blade 24 may be minutely adjusted toward and from the periphery of the disk 19 in order that the thickness of the film of liquid adhering to the periphery of said disk may be regulated.

Pivote d at 28 to the ears 29 extending from the wall 14 of the reservoir is the delivery trough 30, provided with the bottom 31 and the side walls 32. The bottom 31 of the upwardly extending end of said trough is provided with a knife blade edge 33 adapted to engage with the periphery of the disk 19 at predetermined intervals and scrape therefrom the fihn of liquid, and direct the same into the trough 30, whereby it is delivered to the desired place.

In order that the knife blade 33 may be projected toward and from the periphery of the disk 19 to remove the liquid at the desired intervals as well as to regulate the degree of projection of the lmife blade toward said disk, the following mechanism is employed: 4 Keyed to the shaft 18 and adapted to rotate therewith is the hub 35 rovided with the radial arms 36 to which is secured the ring 37 havin graduated mar s 38. A radial arm 40 is loosely pivoted on the shaft 18, it being provided with a tapered bore adapted to engage with the tapered portion 41 of the shaft 18 and clamped thereon in adjusted position by the butterfly nut '42 threaded on the end of said shaft. The end of the arm 40 extends outwardly adjacent the ring 37 and is provided with the pointers 43 adapted to register with the graduated marks-38 on said ring. The end of arm 40 also carries a projecting finger 45 adapted to engage with the rojection 46 of the bell crank lever 47 pivoted at 48 to the side of the reservoir 10. Secured to the end of the provided on its face the arm 49 of the bell crank lever 47 is one end v of a tension spring 51 which is secured at its opposite end to a pin 52 projecting from the side of the reservoir.

The arm 53 of thebell crank lever 47 -is provided on its outwardly extending end with a pin 55 adapted to project into a notch 56 formed adjacent to the inwardly therein a slot 65 adapted to receive the pin 66 which is adjustably mounted in said slot, ashoulder on said pin engaging with one side of the arm 64 and a butterfly nut 67 threaded on the pin engaging with the opposite side of said arm for this purpose. In order that the pin 66 may be delicately adj usted in the slot 65, a set screw 68 is threaded in to the end of the arm 64 and engages with the pin 66.

The downwardly projecting end of the trough 30 is adapted to'rest upon the pin 66 and is held yieldingly thereagainst by the spring 70 interposed between the trough and the reservoir 10. It will be seen by the foregoing mechanism that the lmife blade 33 of the trough 30 may be minutely adjusted toward and from the periphery of the disk 19 in order that a selected quantity of the liquid may be removed therefrom, it being only necessary to loosen the butterfly nut 67, adjust the set screw 68, and then tighten the butterfly nut for this purpose.

The operation of'the device is as follows: Rotary motion in the direction indicated by the arrow is imparted to the disk 19 which carries a film of the liquid upon its periphery, the thickness of said film being regulated by the knife blade 24. When the finger 45f'engages the projection 46 on thebell crank lever 47, said lever is caused-to rock and release the pin 55 from engagement with the slot 56, thus permitting the spring 70 to act upon the trough 30 and draw the blade 33 away from the periphery of the disk 19, whereupon no liquid will be removed from thesurface of the disk. At this time the lever 57 rests upon the'stop pin 72 and the finger61 projects in the path of the finger 62, and the pin 55 rests on thefledge 73 ofthe slot 56. Upon continued revolution of the disk 19 the finger 62 engages with the finger 61 and causes the lever 58 to rock and force the blade 33 again into operative relation with the periphery of the disk and the pin 55 to ride in the slot 56 to lock the blade into said operative position.

It will be observed that the length of time during which liquid is being removed from the periphery of the disk 19 is governed by the distancebetween the

fingers

45 and 62, which distance can be varied, it being only necessary to loosen the butterfly nut 42 and grasp the handle 74 on the arm 40, and adjust the pointers 43 in the desired relation to the graduation marks, and then tighten up on the butterfly nut 42 for this purpose.
