Application ledNovember 9, 19171. Serial No. 201,122.`

To all whom t may concern.'

Be it known that I, ALBERT L. MATfrnsoN,

a citizen ofthe United States,v residingl at Battle Creek, inthe county of Calhoun and State of Michigan, have invented a certain'.

new and useful Auxiliary Sight-Feed, of which the following is a specification, the principle of the invention therein being shown and thefbe'st mode Il have contemplated for carrying that principle into practice.

The invention is a sightY feed to be used formed with a transverse conduitthrough which lubricant is fed from a lubricator or storage under valve controlthrough a sight feed glass from which itis diffused in said steam column'and passes into an engine.

Aside from providing asimple, compact,

economic and effectual auxiliary sight feed', another ob]ect of my invention lsto providev means whereby the* glass to the sight feed columnmay be replaced in case of breakage without retarding the operation of the lubricator supplying oil therethrough.

A further object of my invention is` to provide means whereby should breakage from any cause arise inr thelubricato-r feeding oils thereto the water in the sight feed column cannot iiow int-o saidlubricator or its pump.

A still further object of my invention is to produce a device of the character .which while having the features referred to above will have advantages in mechanical construction hereinafter set forth in the following specification, shown in the drawings and defined in the appended claim.

In the -drawings forming a part of this specification Figure 1, is a side elevation of a preferred embodiment of my auxiliary sight feed.

Fig. 2, is a vertical section of the same.

Fig. 3, is a cross-section on the line m of Fig. l.

Fig. 4, is a reduced transverse view of i the steam column on the line z, e of Fig. 2.

Like marks of reference refer to corresponding parts in the diEerent views, in which A, is an integrally formed steam column the lower extremity of which is internallyy s crewthreaded and adapted to be connected with an elbow or other tubular connection'tothefeed pipe yof a steam cylin-v der of apump'or engine.; This column near its lower extremityis expanded in 'globular' form as l l through which a passage' is formed that leads from a reservoir or lubricator, not shown, thelatter ofwhich connects on the left with an L-valve'iixturej screw-threaded into an offset lof sai-dlglobular.I form.

The expanding vofY the columnis@ for .L theI purposeof affording a steam conduit about the vlubricant passage' 2 vwhereby flui'dityof the latter will be insured under all atmospheric conditions. ,The column Aat its top has an offset andanalined offset@ near its lower end, the ,former off whicli receives the screw-threaded boss ofthe sight-jfeed in'- dicator top, 7', the' latter the screw-threaded" boss of the sight feed indicator bottom, A. The sightV feed indicator'is aglass open ended tube Biitted' at one end into thetop; 7 and at its opposite'` endl with the;k bottom8 and made steam, oil-' and airtight by means of the ring packings l0 and gasket' nuts 11 in the customary manner.-

The top 7 is formedwithanv offset opening 12, one end of which communicates with the column A, the;A other end opening; above the; spacein the sight feed gl'ass B,andthe colui'nn A incase of emergencyl the samein no wise, materially dideringfrom similar apparatus employed with water gages on steam boilers.

. The 'bottom 8 is formed with an offset 1.4. screw-threaded into the offset 6 of the column A and is bored out to form a passage 15 leading through the offset 6 to a vertical drainage 16 controllable by a needle valve 17 alined with said boss on the opposite side of said bottom.

Centrally within the base upon which the sight feed glass B rests, an opening is formed having a funnel-shaped 'bottom upon which a small ball valve 18 fits. The bottom of this valve seat has a small opening.

Screw-threaded into the opening above the valve 18 a small lubricant nozzle 20 is tted. This nozzle extends upwardly within the sight feed glass B sufficiently far to permit a person to observe the passage of oil emitted therefrom in the operation of the indicator.

Piercing the enlarged or globe-shaped portion 1, of the column A from one side is a hole and also communicating with the passage'2 in alinement therewith is a valve seat opening' 20', see Fig. 4, the latter of which is under control of a needle valve 21 fitted within a boss 22 of said column. This valve is for the purpose of supplying lubricant an f engine in casev the indicating glass B leaks about its fittings or becomes broken, or during-time required to install a new glass, in any of which instances the valves 13 and 19 are closed to preclude either the passage of steam from the column A or lubricant from the passage 15 to pass their respective valve openings.

Characteristic features of the indicating gage have hereinbefore been enumerated and described, I will now describe the general operation of the device as operating on an engine both being under normal working conditions. l

The column A having been attached to the lead pipe or steam cylinder of an engine, an L valve xture 3 connected with an oil supply or lubricator, or in case said L fixture is omitted, the offset 4 of said column is connected with said oil supply or lubri cator, steam will enter the column A and through the valve controlled passage 12 enter the sight feed glass B in which place the steam will condense and form a column of water. Water having suiiciently formed in the indicating glass B to a level above the nozzle 2O therein, lubricant is then fed from an oil supply, la lubricator for instance, and enters through the openingsl 2 and 15, from the latter opening of which it passes under control of the needle valve 19 and globe valve 18, into the nozzle 20 from which it Copies of this patent may be obtained for toy rises drop by drop through the water column and floating on therlattes surface passes out through the opening 12 and in infinitesimally small particles is diffused with the steam in the column A, and through gravity force enters the engine.

To those skilled in the art 'to which the invention applies a more extended explanation of the operation and advantages of my auxiliary sight feed is believed will not be necessary. v

Having described my invention, what I claim and desire to secure by Letters Patent 1s:--

An auxiliary sight feed, the combination with a lubricator, a water column sight feed glass having an oil feeding nozzle extending upwardly within said sight feed glass and communicating with lubricant passage from said lubricator, and a valve controlling the passage at the top of said sight feed glass water column, of a steam column extending about said lubricant passage and communicating at its top with said valve controlled passage to said sight feed glass water column, a valve seat having an opening entering from said steam column about said lubricant passage into said lubricant passage, a valve controlling said valve seat opening, a needlevalve interposed within said lubricant passage between said steam column and the nozzle in said sight feed glass for regulating the flow of lubricant through said passage, a ball valve interposed between said nozzle and the seat of said needle valve, to prevent back fiow from said sight feed glass, and means to drain said lubricant passage, substantially as specified.
