SPECIEICATION forming part of Letters Patent No. 308,258, dated November 18, 1884.
(No mod el.)
To all whom t may concern:
Beit known that we, CLARENCE B. Houses and ELIJAH MCCOY, of Detroit, county of Vayne, State of Michigan, have invented a new and useful Improvements in Lubricators, and we declare the following to be a full, clear, and exact description ofthe same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this speciiication.
Our invention consistsof the combinations or" devices and appliances `hereinafter specied, and more particularly pointed out iu the claims.
In the drawings, Figure l isA a longitudinal central section of a lubricator embodying our Fig. 2 is a variation. Fig. 3 illustrates avariation in vwhich the oil-cup H2 and the orifice H shown in Fig. l are dispensed with.
Our invention relates particularly to that class of lubricators designed more especially for use upon locomotives, and in this connection we would have it understood that the lubricator may be single-that is to say, provided with a single oil-exit orifice-or it may be made double, which is the style shown in the drawings-that is to say, provided with two or more oil-exit oritces.
Our invention consists, essentially, in providing each il-eXit conduit with an equalizing-cenduit, said conduits embraced within the body of the lubricator, whereby steam from the boiler is at all times permitted to discharge into the oil-exit pipe', between the latter and the end of the glass tube which delivers the oil to the said exit-pipe, in contradistinction t0 delivering steam upon the oil for impelling the latter through the glass tube to the oil-exit pipe which leads to the parts to belubricated, and in eontradistinctiou to delivering steam through a channel in the bottom neck of the lubricator to a chamber between thelower end of the glass tube a-nd the'oil-exit pipe for seating a valve to close the passage connecting the lower end of the glass tube with the oil-exit pipe, as in Letters Patent No. 262,774.
In carrying out our invention, A represents the reservoir ofthe lubricator, B,its condenser 5 C, a steam-pipe leading to the condenser.
D represents a steam-conduit leading from the condenser and connecting with two steam passages or conduits, D', in the body of the neck has two passages, one, D, for steam, and one, D2, for oil. Hisavalve which,when open, permits the free flow of oil to the parts to be lubricated, and a central orifice, H, eX- tends to the top of the valve-stem, which is here provided with an oil-cup, H2. This oilcup is closed with a valve, H3.
The operation of the device will now be understood. Steam entering through the pipe C condeuses within the condenser B, and the condensed water is fed downward into the oilreservoir. The oil, being thus displaced, is caused to pass in visible drops through the sighttubes, and thence to the part to be lubricated. At the same time steam-pressu re from the pipe D vpasses through the branch pipes or conduits D', and exerts its equalizing pressure back through the-passage D2, thus maintaining an equilibrium within the oil-reservoir and sight-feed tubes.
New in ease one of the glass tubes should break, the engineer simply screws down the valve H until the same is closed, thus cutting off the lubricator from the oil-eXit pipe. He then shuts off the steam for a moment, opens the valve H, and feeds oil temporarily from the oil-cup H2 until he can replace the broken glass tube. The engineer is therefore made independent of the stability of'his sight-feed tubes. It will be seen that by this construction the equalizing-conduits D and D are embraced entirely within the body of the lubricator, so as to present no joints which might spring a leak, and no exterior parts. I prefer to form these conduits in the process ot' casting, so that they shall be in the body ot' the metal itself, although they might be in the form ot' separate tubes inserted within the contines of the body of the lubricator.
A lubricator made as above described possesses all the advantages of an equalizing-lnbri cator, and at the same time is simple and cheap in construction and obviates all external piping, which is necessarily in the way of the engineer.
A f -H 2 308,258 v T \y It will be observed that the steam, in the construction shown, does not lead from the condenser directly down into the top of the sight-feed tube, but, on the contrary, it discharges into the valve-chamber at the end g of the oil-exit pipe G. It then reacts back through the oil-passage D2. This prevents the steam from coming directly into contact with the packing at the top of the visible-feed tube. and so obviates the liability of damaging the said packing by the combined eiiects of heat and oil. The variation shown in Fig. 2 represents the steam-pipe as only partially embodied wit-hin the body of the reservoiri. e., the steam-pipe starts within the condenser, near its top, as shown, and passes down within the condenser to the neck between the condenser and the oil-reservoir.
From this point exterior steam-passages, D3,
convey the steam to the oil-exit conduit or conduits, instead of employing the interior conduits, D. (Shown in Fig. l.)
We would have it understood that our invention contemplates a steam-equalizing conduit embraced either wholly or partially within the confines of the lubricator.
The steam-conduit D serves as a heater to keep the contents of the oil-reservoir hot and in a thoroughly Huid condition, regardless of whether steam is on the cylinder or not. This enables the cup to be used on the lubricator in the coldest weather. The same effect is accomplished, however, though not in so perfect a degree, by the construction shown in Fig. 2, the heat in this last case being conveyed to a neck between the condenser and the reservoir, and also to the vicinity of the top of the sight-feed chamber, from which points the heat is conducted by the metal to the oil-reservoir.
Ve would have it understood that we do not necessarily provide the valve H with Van oilcup at its top and a central orifice, H', for this may be simplya valvefor throttling more or less the oil-exit passage. In fact this is one of the principal objects of this valve, and the provision of the oil-cup at its top is an expedient which may or may not be employed, depending upon the desires of the purchaser or other circumstances.
l. The combination of the oil-reservoir, the visible-feed tube through which the oil rises, and the oil-exit connected by a passage with the upper end of the visible-feed tube, with a steam-conduit at the top of the reservoir for discharging steam into the oil-exit between the latter and the upper end of the visiblefeed tube, substantially as described.
2. The combination of the oil-reservoir, thev condenser, the visible-feed tube through which the oil rises, and the oil-exit connected by a passage with the upper end of the visible-feed tube,with the steam-conduit formed in the top wall of the oil-reservoir for discharging steam into the oil-exit between the latter and the passage which connects the visible-feed tube with the oil-exit, substantially as described.
3. The combination of the oil-reservoir having the neck F at its upper end and the visi- 7o ble-feed tube through which the oil rises, with the oil-exit connected through the said neck with the upper end of the visible-feed tube, and the steam-conduit in the top portion of the reservoir for delivering steam into the oilexit between the latter and the upper end of the visible feed tube, substantially as described.
4. The combination of the oil-reservoir, the visible-feed tubes at the sides thereof, through 8o which the oil rises, and the necks at the top of the reservoir, having oil-exits connecting by passages. with the visib1efeed tubes. with the condenser, and the two steam-conduits in the top wall of the reservoir for delivering steam 8 5 into the exit between the latter and the passages connecting said oil-exits with the upper ends of the visible-feed tubes, substantially as described.
5. The combination of the oil-reservoir, the 9o visible-feed tubes through which the oil rises, and the neck F at the top of the reservoir, having the space g, and the oil-exit, with the steam-conduit in the top wall ofthe reservoir for deliveringV steam to the oil-exit between the latter and the upper end of the visiblefeed tube, and the throttling-valve governing the oil-exit and the fiow of oil and steam from the said space in the neck, substantially as described.
6. The combination of the oil-reservoir having a neck, F, provided with an oil-exit, and the visible-sight feed-tube through whichthe oil rises to the oil-exit, with the valve H, arranged in the neck to govern the'oil-exit, and 105 having an orifice through its stem and an oilcup at its top, and a valve extending through the cup and governing the orificein the valvestem, whereby oil may be fed from the said cup if the visible-feed tube becomes broken, Ilo substantially as described. l
In testimony whereof we sign this specification in the presence of two witnesses.
