Application led October 2,5, 1910. Serial No. 589,029.
To all whom it 1mg/concern:
Be it known that I, BENJAMIN F..- How ARD, acitizen of the United States, residing at Indianapolis, inthe county of lMarion 5 and State oflndiana, have invented certain new and useful Improvements .in Lubrica-k itors, of which the following is a specication.
` fThis invention relates to improvements in mea-ns for economically supplying lubricating oils to the surfaces of machinery subJect to friction in the presence of steam, and the object of the invention is to thoroughly .atomizethe oil andmix it with the steam before themixture reaches the wearing parts to be lubricated.
I accomplish the object of the invention by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a view in side elevation of my' 20 invention applied in operative position to a steam supply pipe. Fig. 2 is a view of same in end' elevation, and `Fig. 3 is a vertical section on the line 3 3 of Fig. 2.
Like characters of reference indicate like parts throughout the several views of the drawings. I 4. represents a pipe for supplying steam to a mechanism, such, for example, as an' engine cylinder, in which is a reciprocatingy piston, and 5 is a minor communicating pipe,
through which a portion of the steam is diverted'from the mainfpipe 4.
6 is v`a steam box supported adjacent to the pipe 4 and communicating therewith y through the pipe 7. The pipe 5 enters the l box 6 through the remote end of the latter and terminates within'the box opposite the opening into pipe 7 with suicient clearance between the end of pipe 5 and inner wall'of 40 they box to .permit the condensed steam toI pass down freely and accumulate at the bottomof box 6.
Above the box 6 is an'oil reservoir 8 having a plug 9 screwed, into its bottom and adjust-able vertically. rlhis plug is perforated and forms a nipple through Ywhich oil from reservoir 8 is discharged. The upper end of the plug 9 isprovided with a conical seat for the correspondingly shaped lower end of a needle. valve 10. The valve lO is screw-threaded and passes outthrough a threaded opening in the top of the'reservoir Y lSpecification of Letters Patent.
l andA is provided with a Patented May 16,191l..
hand lwheel 11 by which the needle valve 10 isA screwed up ror down to regulate the quantity of oil discharged through the plug-nipple 9. The top of the reservoir 8 has a removable cap in which the needle valve is mounted which permits the needle to be' readily removed and affords access to the interior of the reservoir for the purpose of cleaning the latter. .1t will be noted that the upper end of the plug 9- terminates above the bottom of reservoir 8 whereby sediment will accumulate around the plug and will not enter the nipple -to clog its discharge. '.The nipple or plug 9 discharges into the open end oan oil-tube`12, which tube extends vertically through the wall of the pipev 5, to theinterior of the latter and is bent to'ward thel discharge end of pipe 5 and'- is continued within thelatter, parallel with it, andr terminates adjacent to the end of said .pipe5t Y A Live steam-passing from pipe 4 through pipe 5, around the oil-tube 12, so heats and volat-ilizes theoil in said tube that Vit is discharged frm the end of theftube in the form of a vapor which mixes readily with the steam discharginen from pipe 5, and is' carried through/che pipe 7 into the Apipe 4, and therein against the opposite inner wall of pipe 4 and becomes thoroughly mixed with the steam passing through the lattera A valve 13 is provided in pipe 5to regulatethe quantity and pressure of steam supplied through pipe 5,
The bottom vof rthe steam-box 6 has a removable plug 14 by the removal 'of which access is afforded to the interior of the box f for the purpose of removing` vthe water 'of condensation and any sediment and accumulated impurities. To permit this to be done without danger of back pressure of steam from pipe 4 through the pipe 7, the latter is provided with a valve 16, by vwhich .communication through pipe 7 at such tunes,
maybe cut off.`
The oil reservoirfS is provided with a\ a vacuum in the reservoir which would interv terewith.' the oil ow.
n g L into the main pipe.
`As a detail of construction lvhave here "shown the oilv` reservoir and nsteam box 6 as ,means for supplying oil and volatilizing it bythe heat of the'steam of saidbranch pipe and for discharging the volatilized oil into the discharge from-said branch pipe, and. means for then discharging the volatilized oil and steam together into the main pipe.
2.
