LU BRICATOR ATTACH M'ENT.

SPECIFICATION forming part of Letters Patent No. 361,435, dated April 19, 1887.

l Application filed February 11, 181%?. Serial No. 227,311. (No model.)

To all whom it may concern: y

Be it known that I, ELIJAH McCoY, of Detroit,county of`Wayne,State of Michigan,have invented a new and useful Improvement in Lubricator Attachments; and I declare the'following to bea full, clear, and exact description of the 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 ofthis specifica tion.

My invention relates to an improved lubrieating attachment in connection with air-brake cylinders; and it consists ofthe devices and appliances hereinafter specified,and more particularly pointed out in the claims.

lIn the drawings, Figure 1 is a view inelevation showing the lubricating device attached to the steam-pipe communicating with an airbrake cylinder. Fig. 2 is a separate view, partly in section, ofthe features embodying my improvement.

A represents any ordinary lubricator or oilreservoir.

B represents an air-brake cylinder; C, the steanrpipe communicating with the boiler and said air-brake cylinder; and D is an oilgexit pipe, leading from the reservoir or lubricator A, and communicating with my improved attachment, and thence to the said steam-pipe.

Heretofore, where a visible-feed'lubricator has been employed for lubricating the airbrake cylinders, it has been found necessary to keep on hand one or more blind-feed lubricators,77 for the reason thatshould the visi-` ble-feed glass be accidentally broken ,resort must be had to the blind lubricator to takethe place of the visible-feed lubricators for lubricating said cylinders until opportunity is affordedto replace said visible-feed glass.

The necessity heretofore existing of provid'- ing the blind lnbricator in addition to the visible-feed lubricator for this purpose has necessitated a great increase of expense and much annoyance; and it is the purpose of my present invention to provide an attachment to be 1ocated in connection with the said steam-pipe, which shall dispense with the necessity of this eXtra blind lubricator, and to provide a single apparatus which shall take the place of the visiblefeed lubrioator and the blind lubrica- I carry out my inchamber may communicate through said hollow neck with the steam-pipe. The valve itself is constructed with a hollow stem, F', to communicate with the hollow neck of the oilvaporizing chamber when seated. The upper end of said valve terminates in a slush-cup, F2, communication from said cup with the passage in the hollow stem of the valve F being controlled by a T-valve, G. This valve G is ,eugagedlwith a screw-tapped case, G', within the said cup,said case being provided at its base with orifices g g',to facilitate the passage of oil from this said cup to the passage of the said valve-stem F. These -orices g g overcome the necessity of completely removing the valve from said case to permit the passage of oil from the said slush-cup into the hollow valve-stem F. As thus constructed, the valve G need only be lifted from its seat to allow the discharge of the oil from said cup. The oil from the oil-exit pipe-may communicate with the oil-vaporizing chamber in any desired Emanner without departing from the principle of my invention; but I prefer, however, to locate upon said vaporizing-chambera visible-feed glass, H, having proper connections at its base with the oil-exit pipe and at its upper end with said vaporizing-chamber, so that the oil may pass from the oil-exit pipe up through the visible-feed glass H and into the oil-vaporizing chamber, and thence through the neck e in va- IOO the valve G, oil from the slush-cup will find ready passage into the steam-pipe to supply the necessary lubrication.

To operate the valve F, which is liable to become excessively heated, I prefer to provide it with a handle, f2, of any suitable non-conducting material, so that said valve may be readily operated by the bare hand. When it becomes necessary to cut off the feed from the oil-exit pipe, steam may be shut oii from the steam-pipe to permit the valve G to be opened and oil to be fed from the slush-cup.

This dev'ice is simple, economical, iiotlikely to get out of order, and when the air-brake mechanismisequipped therewith theengineer is always provided with readily operative means to insure the lubrication of the airbrake cylinders without the necessity, heretofore liable to arise, of having to exchange lubiieators.

\Vhat I claim isl. In alubricating apparatus, the combination of a steam-pipe having in communication therewith au oil-cliamber, an oil-pipe coniniunicating with said chamber, a valve to control the communication of the chamber with said steam-pipe and provided with a slushcup arranged to communicate with said steampipe, and a valve to control the communication of said slush-cup with the steam-pipe, substantially as described.

2. In a lubricating apparatus, the combination of a steam-pipe having in communicatioii therewith an oil-chamber provided with a visible-feed glass, au oil-pipe communicating with said chamber through said glass, a valve to control the communication of said chamber with the steam-pipe and provided with a slush-cup communicating with said steampipc, and a valve to control the communication of said slush-cup with said steam-pipe, substantially as described.

3. In a lubricating apparatus, the combination of a steam-pipe having in communication therewith an oil-chaiiiber provided with a visible-feed glass, an oil-feed pipe communicating with said chamber through said glass, a valve to control the feed of oil from said oilpipe through said glass, a valve in said chamber to control its communication with the steam-pipe, and said valve having a slush-cup communicating with said steam-pipe and provided with a valve controlling its communication with said steam-pipe, substantially 'as described.

et. In a lubricating apparatus, the combi- 'tion therewith an oil-chamber, an oil-feed pipe communicating with said chamber, a valve to control the communication of said chamber with said steam-pipe, said valve constructed with a hollow stem to communicate with said steam-pipe when seated and provided at its upper end with a slushcup communicating with said hollow-stein, a valve to control the communication of said slush-cup with said stern, said cup provided with a screw-tapped case to receive said valve, said case coustructed with one or more orifices at its base to permit the discharge of oil into the said stem when its valve is loosened from its seat, substantially as described.

6. The combination, in a lubricating apparatus for an air-brake cylinder, of asteampipe, au oil-chainber communicating with said steam-pipe, an oil-pipe leading from a lubricator or oil-reservoir communicating with said chamber, a valve to control the communication of said chamber with the steam-pipe and having a slushcup communicating with the steam-pipe and provided with a valve controlling its communication with said steam` pipe, substantially as described.

7. The combination, in a lubricator for an air-brake cylinder, of a conduit leading fioin the main lubricatoi', a visible -fecd glass, through which said conduit communicates with the airbrakecyliiider, a valve to control the communication of said conduit with said cylinder, and, in connection therewith, means for feeding oil to said cylinder when the supply is cut off from said conduit, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
