AUTOMATIC OILER Filed March 5, 1952 IN V EN TOR. 5 j M )4 By W ATTOWS' Patented Mar. 23, 1954 2,672,951 AUTOMATIC OILER Ormondc Bogert, 'Maplewood, N. J., assignor to Leiman Bros., 01 New Jersey Inc., Newark, N. J a corporation Application March 5, 1952, Serial N 0. 274,974

My invention is directed to automatic oilers of the suction operated wick feed type.

The object of my invention is to provide certain Claims. (01. 184-59) improvements in the construction, form and arrangement of the several elements of the oiler whereby the proper and efficient operation of the oiler is ensured under the various conditions to which it may be subjected.

A practical embodiment of my invention is shown in the accompanying drawings, in which:

Fig. 1 represents a side view of the oiler, partly in section;

Fig. 2 represents a detail end view, wards the suction outlet;

Fig. 3 represents an enlarged top plan view of the oiler, the main oil reservoir, and the cup cover, being partly broken away;

Fig. 4 represents a detail vertical section taken in the plane of line 44 of Fig. 3; and

Fig. 5 represents a detail vertical section taken in the plane of the line 55 of Fig. 3.

The oil cup is denoted by I, the cover hinged thereto by 2, and the open bottom main oil reservoir by 3. This main oil reservoir is preferably permanently mounted on the cover 2.

The cup I has an oil reservoir 4, the open top of which is closed by the cover 2. This cup also has a vertical oil drip well 5, the upper end of which is in open communication with the upper end of the cup reservoir 4 through a short passage 6. The upper end of this drip well 5 is also in open communication with external air, in the present instance by a shallow groove or passage formed in the bottom of the cover 2. This open passage I eliminates any vacuum forming in the cup reservoir 4 which would tend to raise the oil level therein.

The cup I also has a suction outlet 8, which may be connected to any suitable suction source as a suction pump (not shown) This suction outlet 8 is shown as laterally disposed.

The lower end of the oil drip well 5 is in open communication, through ashort lateral passage 9, with a passage l0 which leads upwards to a point in the cup above the cup reservoir 4 and the drip well 5, and then downwards to the laterally disposed suction outlet 8.

An adjustable nozzle ll leads downwards through the cover 2 from the main oil reservoir 3 into the cup reservoir 4. The Vertical position of the mouth of this nozzle ll serves to determine the oil level in the cup reservoir 4. It will be noted that the higher this oil level is in the, cup reservoir, the faster the oil feed Will be therefrom.

looking to- In the present instance, the vertical adjustment of the nozzle H is obtained by providing it with a screw threaded engagement with the cover 2. A lock nut l2, which is threaded on the nozzle l 1, serves to lock the nozzle in any of its vertical adjustments.

A wick 13 leads upwards from the oil in the cup reservoir 4, then through the short passage 6, and then down into the drip well 5. This wick I 3 is longitudinally grooved for facilitating its oil feed and the wick may be composed of any suitable non-porous material, such as metal.

The wick l3 serves to feed the oil from the cup reservoir 4 into the drip well 5 by a combination capillary and syphoning action, and then through the passages 9 and in to the suction outlet 8.

By locating the upper portion of the passage l0 above the tops of the cup reservoir 4 and the drip well 5, any syphoning of the oil is prevented when the suction is cut ofi therefrom.

The bottom of the drip well 5 may have a depression l4 therein for receiving any slight accumulation of oil which might drop when the suction on the oiler is cut oil.

Releasable means, as a spring catch l5, may be provided for firmly holding the cover 2 in its closed position.

It will be noted that when the suction pump is working, both air and oil will be drawn from the oiler, and that when the suction pump is not working no oil will be drawn into the suction outlet.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from my invention, hence I do not wish to be limited to the form herein disclosed.

What I claim is:

1. In an oil reservoir, a cup, a cover hinged thereto, releasable means for holding the cover closed, a main oil reservoir mounted on the cover, said cup having an oil reservoir, a drip well open at its upper end to external air and also to the cup reservoir and a suction outlet open to the lower end of the drip well through a passage which is higher at one portion than the cup reservoir and the drip well, an adjustable nozzle leading from the main reservoir into the cup reservoir, and a wick connecting the cup reservoir and drip well.

2. In an oil reservoir, a cup, a cover hinged thereto, releasable means for holding the cover closed, a main oil reservoir mounted on the cover, said cup having an oil reservoir, a drip well open at its upper nd to external air and also to the ,cup reservoir and cup reservoir and a suction outlet open to the lower end of the drip well through a passage which is higher at one portion than the cup reservoir and the drip well, an adjustable nozzle leading from the main reservoir into the cup reservoir, and a grooved wick of non-porous material connecting the cup reservoir and drip well.

3. In an automatic oiler, a cup, a cover therefor, and a main oil reservoir mounted on the cover, said cup having an oil reservoir, a drip well, a passage connecting the upper ends of the cup reservoir and drip well, and a passage connecting the upper end of the drip well with external air, a, laterally disposed suction outlet, a passage leading upwards from the drip well to a point above the cup reservoir and the drip well and then downwards to the suction outlet, a nozzle leading from the main reservoir through the cover into the cup reservoir, and a grooved wick leading upwards from the cup reservoir,

then through the first named passage and then downwards into the drip well.

1. In an automatic oiler, a cup, a cover therefor, and a main oil reservoir mounted on the cover, said cup having an oil reservoir, a drip well, a passage connecting the upper ends of the drip well, and a passage in the cover connecting the upper end of the drip well with external air, a laterally disposed suction outlet, apassage leading upwards from the drip well to a point above the cup reservoir and the drip well and then downwards to thesuction outlet, a nozzle leading from the main reservoir through the cover into the cup reservoir, and a grooved wick leading upwards from the cup reservoir, then through the first named passage and then downwards into the drip well.

5. In an automatic oiler, a cup, a cover hinged thereto, a main oil reservoir permanently mounted on said cover, and releasable means for holding the cover closed, said cup having an oil reservoir, a drip well, and a laterally directed outlet, a passage connecting the upper ends of the cup reservoir and the drip well, an air passage in the bottom of the cover leading to the upper end of the drip well, a passage leading upwardly from the bottom of the drip well to a point above the cup reservoir and the drip well, and then downwardly tothe suction outlet, an adjustable nozzle connecting the main reservoir with the cup reservoir, said nozzle being threaded through the cover, a nut on the said nozzle for looking it in its adjustable position, and a grooved wick of non-porous material leading upwardly from the cup reservoir and then downwardly into the drip well.
