SPECIFICATIN forming' part of Letters Patent'No. 658.019, dated September 18, 1900.

Application filed April 30, 1900. -:Serial No. 14.886. (No model.)

To all whom, it may concern:

Be it known that I, JOHNPOWER, a citizen of the United States of America, and a resident of the borough oi' Bronx, city, county, and State of New York, have invented certain l new and useful Improvements in Lubricaiors check-valves, and to produce a simple and.

or Oil-Pumps,of which the following isa specification.

This invention-relates to`new and useful imf provements in lubricators and refers to that class of lubricators generally used to lubricate steam-engines and the like.

The object of the invention is to provide improved means for pumping oil or other 4lubrieating compound from a reservoir and feeding it into a steam-pipe or other conductor through which it is led to the parts to be lubricated to avoid the use of check-valves, which are always liable to be troublesome, and to utilize-the difference in the specific gravity between a liquid lubricant and another liquid, preferably water, instead of easily-constructed pumping mechanism and improved regulating means therefor.

With these objects in view my invention consists of the novel devices and the arrangement and construction of the parts, as hereinafter described, and illustrated in the accompanying drawings.

. In the drawings, Figure l is a frontelevation of a lubricator made in accordance with my invention and of my preferred form of construction. Fig. 2 is a perpendicular sectional view taken on the dotted line A A in Fig. 1 and shows the parts as they appear looking to the right in the drawings.4 Fig. 3

is a similar sectional view to Fig. 2 and shows a modified form of constructing some of the parts and also shows improvements which may be combined with the form shown in Figs. 1 and`2.4

Referring to the several figures, the parts when similar are designated by like referwal13, separating the oil-reservoir and the.

the valve-stem 13.

threaded to the fitting 12 and extends up-l water-reservoir. A threaded couplingl pro- Jectiou 4 isformed upon the rear wall of the Water-reservoir and is screwed into a steampipe 5, upon which the lubricator is supportis a steam-engine supply- `pipe and is the usual channel through which ed. The pipe 5 oil is fed to the valves and cylinder.

Formed upon the rear wall within the condenser is a semi dish-shaped hood (i, located opposite the coupling 4 and having its conv screwed into a threaded aperture in the bot-- tom of the reservoir] and is providedwith a packing-nut 14 for containing packing for The valve-stem 13 is wardly to and is adapted for regulating the passage 11 vthrough the nipple 10. A small stem 18 upon'the upper 4end of valve 13 enters the passage 11 in thenipple, and being A nipple 10 is screwed into a threaded smaller than the passage leaves a space through which oil or water can be forced. This stem 13 when adjusted longitudinally regulates the cubical size of the space for liq- A pump-plunger 1 6v uid in the passage 11; is mounted in an aperture which extends through the front wall of the oil-reservoir and` through an enlarged portion of the partitionwall 3 and opens into the reservoir. The outer end ofthe pump-plunger is furnished with a yoke 17, which is elongated laterally relative to' the plunger and which is adapted to be engaged by the crank 18, by which the plunger is reciprocated. A packing-nut 19 is screwed into a threaded recess in the front of the lubricator and compresses the packing 2O against the plunger. A crank-shaft 18 is journaled in a bracket 22, fastened upon the front of the lubricator, and a worm gearwheel 23 is `fastened upon the crank-shaft outside the bracket. A worm 24 is mounted on a'shaft 25, supported by the bracket 26, and engages With and -is adapted for rotating the wheel 23. A pulley-wheel 27 is fastened upon the worm-shaft and has a groove in its periphery for receiving a driving-belt.' A tubular filler projection' 30 is formed upon the side wall of, the lubricator, opens into the oil-reservoir, and is adapted for being closed by the filler plug 31.

A drain-valve .34 is attached to the bottom of the oil-reservoir and is used for emptying water from the reservoir. An opening is formed in the upper wall of the water-reservoir and is normally closed by the plug.

The lubricator operates as followst The oilreservoir is tirst iilled'with oil. Water will accumulate in the condenser or water-reser- Voir 2 and elevate to the level of the outletpassage S under the hood 6. ley-wheel 27 is rotated by a belt connected to a wheel on the engine, the worm 24 will r0- tate the wheel 23 and the crank-shaft 18. The crank will then operate the plunger 16. Upon vthe ontw-ard stroke ofthe plunger some of the oil in the oil-reservoir will he drawn into the pump-chamber, and as the pressure in the reservoir will thus be made less than that in the water-reservoir enough water from the water-reservoir will be drawn into the oil-reservoir through the passage 11 in the nipple to compensate for the oil taken into the pumpchamber. As soon as water ent-ers the oilreservoir it will descend to the bottom because it is heavierthan oil. When the pumpplunger is forced inwardly, the pressure in the oil-reservoir will be increased to greater than that in the water-reservoir, vand consequently the oil which is near the passage 11 will be forced upwardly through the passage and into the water in the water-reservoirand directly beneath the hood, where, it being lighter than the water, it elevates to the upper part of the pocket under the hood and flows through the passage Sinto the steampipe, from whence it will be carried by the steam to the parts to be lubricated.

The quantity of o'il which is displaced by the pump-planger is equal at each stroke, and consequently the varia-tion in pressure in the oil-reservoir is alsoequal at each stroke.

I. is obvious that the throw of the plunger could be regulated by changing thel throw of the crank, but as that would be undesirable without having an adjustable-crank a more simple Way for regulating the amount o-f the oil which is fed through the passage 11 is employed. This is done by adjusting the valvestem 13,' longitudinally to regulate the size of the opening' through the passage 11 in the nipple 10. ,a

It win be obvious matwhite the' tum-10m01- is operating the passage 11 will always be filled vwith either oil or Water and that the amount of the oil or water therein can be regulated by adjusting the stem 13', that by withdrawing the sternY and increasing the size of thespace for the liquids, so that the passage When the pul-v sage and fill the passage with water, and during the inward stroke ot' the plunger the wa.-

ter will be returned to the water-reservoir and the passage will again be filled with oil, but no oil would be forced through the passage. Thus it .will be seen that the less the cubical sizeof the space for liquid,in the passage the greati` will be the amount of oil actually fed therethrough. l

'The threaded part of the valve-stem 13 where it engages with the fitting l2 is of sufflcient length to allow of the necessary adjustment of the stem 13'.'

Itis not necessary to use a ,condenser to supplyv the water for taking the place of the oil nor to lead the oil through'a steam-pipe. The water or other liquid heavier than the oil or lubricant can be held in a reservoir above the lubricant-reservoir, and the lubricant can bc carried therefrom in a tallow pipe or other suitable conductor to the place where itis used.

In the modification shown in Fig. 3 the body of the lubricator is formed similar tothe form# shown in Figs. 1 and 2. The lower chamber 1n is the'oil-reservoir, andthe upper chamber 2 is the water reservoir and condenser. The inverted dish-shaped hood 6 forms a pocket and a leader for the oil to the passage 8 simi.- lar to that described relative to Figs. l and 2.I The passage 7iL is the steam-inlet to thc condenser. The nipple 10 has an angular aperture therethrough, the valve-seat at the month of which is upon the side of the nipple facing forwardly. A threaded tubular fitting 19 is screwed into an aperture in the front of the oil-reservoir l, and 'a packingnut 38 is screwed into a recess in the titting and holds the packing 2Oa in place. part of the aperture through the packing-nut 38 is threaded for engagement with the threaded part of the'pump-pl-unger 16, The said plunger 16 is mounted in the bore of the tittiug 19a and through the packing-nut 38, and the inner end thereof is formed conical to constitute a Valve for regulating the passage 11n through the nipple. It will be seen that while the threads on the pump-plunger are in engagement with the threads in the packing-v nut 88 the plungercan beused as a valve and that by unscrewing the plunger from the threads it mayfthen'be used as a pump-piston. ."looperate the lubricator when made' in this form, unscrew the pump-plunger 16'er until the threads thereon are freeA from the packing-nut 38 and then by reciprocating the plunger the oil and water will change" places and the oil'will Abe led to its conducting-pipe in the same manner as. described in reference to thefrst-,named form. When the lubricator is at rest or not feeding and the passage 'in the nipple, in eitherl form, is left open, the water and oil will not change IlO places. This is due to the fact'that the passlight that in a small passage less than the diametrical size of a drop of either liquid the pressure is not suticient to cause the drops to pass each other. Hence the necessity' for checkvalves is avoided and gravity is `utilized.

Other lubricants than oil can be used, any liquid heavier than the lubricant can take the place of water, and other pressure-changing means can be applied to either reservoir without departing from the spirit of my invention.
