AUGUSTUS BOWSER, OF FORT WAYNE, INDIANA.

DISTRIBUTING SYSTEM FOR LIQUIDS,

To all whom ii may concern:

Be it known that I, AUGUSTUS Bowsnn, a citizen of the United States 01: America, and resident of Fort Wuyne, in the county of Allen and State of Indians, have invented certain new and useful Improvements in Distributing Systems for Liquids, of which the following is a specification.

This invention rel ates to improvements in distributing systems for liquids, and is especially intended for use in delivering oil and the like to various departments of factories Where inflammable fluid is employed.

'l he objects of the improvements are first, to rovide it device of the class described wlnch will automatically eii'cct drainage of the distributing pipe in. case the letter becomesexcessivcly hot due to coni'logrstion; and second, to sll'ord a constant head of fluid in. the ilistributint;- pi pc supplied from suitable reservoir.

The objects of this invention. are accom plished by the construction iilustrsted in the ucci'nnpsnying drawings in which Figure 1 is it side view of the s pnrutus' which controls the supply of air to t is rcservoir, and the outlet oi sir therefrom through the vent pipe, part ol the apparatus being shown iii-vertical section; "Fig. 3 is another view of the some apparatus in e plnnh at' right angles to Fig. 1 Fig. 3 an enlarged detail. view, showing partial horizontal section of the controlling valve and its case; Fig. 4; is aview showing the a. plicetion of this invention in connection wit it building,

various points beneath the expansion tank 5, are suitable faucets 7 through which liquid may be drawn from the distributing pipe 5. These faucets may have a suitable measur ing apparatus 8 in connection therewith to indicate the amount of liquid drawn through them respectively. The particular construction of said measuring apparatus is immaterial to the present invention and may be of any construction adopted for that pur ose. '"Yhe lower end of the distributing pi e ends into the reservoir 3 and extends to t is bottom thereof where it has open communication therewith. The reservoir 3 is normolly closed to externsl atmosphere and is such as to be capable of withstanding interns]. pressure-to the extent required for the purpose which hereinafter appears. n

An air pipe 9 leads into the reservoir 3 and has free communication therewith at the up- P l for connects with said'vslve cese at the end thereof; c

A vent pipe 13 connects with the valve case 10 at the top thereof, and the valve 1 in said case has a port 15 which affords cornmunicstion between the pipe 9 and vent pipe 13 when turned accordingly. The valve 1% hes also a port 16 which, when the K vc is properly turned, affords coinnuinic: tween the pipe 9 and supply pipe valve is slightly tampered and its up valve case which corresponding l epcred, and the valve is held. in seated p i i on hy s coil spring 17. A small port 18 leads from the port 36 to the forward endof the valve and admits sir thercthrough to the forward end of the valve cuss, snd thereby the valve is balanced therein I An air compressor 1?) has connection with an air reservoir 20 by means or apipe 21 end. the letter has connection with the sup ly pipe'l2 through the medium of s step-vel 22 the latter being of any-suitable construction. Each of'the ipes 21' sndl have in. age 23 and 24 respectively. The object o the coin- .pressor and sir reservoir 20 isto meintoin e min the reservoir 3.

constant source of supply of air under pres- I ing pipe 5, The expansion tank I: is so prosure', and the object of the step-valve 22 is to ail'ord a supply of air through the pipes 12 and 9 to the reservoir 3, at a reduced but unvarying pressure.

In connection withthe pipe 12 is a popvalve 25 which rests upon a seat 26 in the cylinder 27. The valve 25 is held on saidseat by a compression spring 28 which may be made to ttCtjVli/llmore or less force against said valve by means of a screw plug 29. The lower part of the cylinder 27 has communication with the adjacent cylinder 30 at thelower end ol" the latter, and a piston head 31 is movably mounted in'theeylimler 30 at a point therein above the port 252 which connects the two cylinders. -The piston 31 is mounted rigidly upon a rod 32;, the lower end oi which passes through a suitable stuiling box. 34 into a slotted lug 35, the latter projecting from the lower part ol the cylinder 27. The upper end ol the rod 33 projects through the top ol the cylinder 30. cylinder 27 has connection, by means oi a pipe 36, with the supply pipe 12, and air from the latter, when of sullicient pressure, is adapted to enter the cylinder 27 by lilting the valve 25 from its seat.

The valve 14 has'astem 37, and thereon is rigidly mounted an arm 38, which has pivoted thereon at its outer end a lever 39. The arm 38 has also at its outer end a bracket 40 adapted to hold said lever in horizontal posi tioii when the l'ormer projects vertically upward, and the leverilll has at its extending end a weight 41, and at its opposite end a perforated extension 42. 'hen the arm 38 is moved to its upward position as indicated in Fig. l the extension 42, of the lover 3!), projects into the slot ol' the lug 35, and is engaged by the lower end of the rod 33 and thereby held in the'position shown. \'Vli.ei 1 the arm 38 is in the position just described, the portlti ol' the valve 14 c1immunicates with the pipes l and 12, while the port 15 of said valve is closed by the wall oli the case. l0, and when the arm'fiH is in the position shown in dotted outline in Fig. l, the-port l5'connects the pipes ll and 125, and the port 16 is then closed at one end by the wall of the case it).

in the operation of this invention the reservoir Ii is tilled with liquid through the pipe 4 which is al'terward -closed tightly. The air reservoir 20 is then charged with air under high pressure by means of the air compressor, and conse p1ently air passes from said air reservoir through the step-valve 22into the pipe 12 from whence it passes through the port 16 ot the valve 14 into thepipe .l and lt will therefore appear that a constant air pressure-is maintained in the reservoir 3, which has the' ell'cct ol' displacing the liquid therein so as to cause the latter to pass upward into the distribut- The stance.

portioned as to be su'l'liciently capacious to compensate for the rise of liquid in the dist ributing pipe b recei'ving'the air iirsaid distributing pipeaiiove theliquid therein. The

capacity of the expansion tank issuclrasto permit the liquid in the distr1but1ng p1pe to rise therein to a pointabove the connection of the'uppermost faucet 7 with said pipe.

As the air in the reservoir 3 is expended, the

pressure -in said reservoir is.n-1aintained by admission of air through the step-valve 22 from the air reservoir 20, so that the oil is maintained at a level in the distributing pipe at a point above the uppermost ol the faucets.

1f the distributing pipe should become excessively heated, the oil therein would expand and consequently the pressure in the reservoir l, and pipes 9 and 12 would thereby become raised, and it is the intention that when the pressure in the pipe 12 becomes raised above its normal pressure, the valve 25') will thereby become lifted and consequently air will enter the cylinder 27 and pass through the port 32 into the lower partol' the cylinder 30 which has the ell'ect of raising the piston 31 therein. When the piston, 23 is raised,

the lower end ol the rod 3. 5 is withdrawn from engagement with. the extension 12 of the lever 39, and when said lever is thus released,

the weight 41 at its outer end gravitates and carries the arm 38 to the. position shown.1n dotted outline in Fig. 1, and the valve 14. is

' corresj'iondiugly turned to the position shown in Fig. 3). Thus the supply oi air l'rom the pipe 12 to the reservoir 3 is thereby shut oil', and the pipe 5) is then connected by n'ieans ol the port 15 with the vent pipe 18, so that the air in the reservoir 3 will then be free to escape through the pipes 9 and 125. hen the reservoir 3 is thus relieved ol internal pressure, the liquid in the distrilnitingpipe 5 will become forced to reenter the reservoir 3 because of the expansion of the air in the tank 6.- While the apparatus is in this condition the escape ol' liquid l'rom the reservoir 3 is prevented, and should the distributing. pipe iecome broken or destroyed withthe build-' ing in case of conllagration, the'liquid in the reservoirwill not pass out the remaining part of the' distrilmting pipe and thus cause the (amilagration to he aggravated.

ll' it be desired at any time/to cause the return of the liquid from the distributing pipe,

it is only necessary to lift the weight l l so as -to.disengage the extension 42 l'rom the lowel" end of the rod 33 and then turn the arm 38 downward, when the result will be the same as just described' 'lo again raise theliquid in the distributing pipe, it is only necessary to raise the arm 38 to a vertical position and connect the extension 42 ol'the lever to the lower end of the rod 325 as in the ii'rst iuv tion therewith a dietn therewithand eonneoting pipe erfhst'iveiiftke'ennne i velve is turned; a. welghtedilevereri gonnee- Petentis:
