AMMONIA DlPPER-VALVE.

SPECIFICATION forming part of Letters Patent No. 482,233, dated September 6, 1892.

Application filed April 18. 1892. Serial No. 4 model-l To all whom 't may aoncern:

Be it known that I, JACOB DREISERNER, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in AmmoniaDipper-Valves, of which the following is a full,clear, and exact description, reference being had to the aocompanying drawings, forming part ot' this specification.

This invention relates to an am nonia-valve for charging and discharging the gas-cylinders in which the amnonia is shipped, and which valve has a branched du plex integral valve-joint, with which is combined a pendent dipper-pipe, whose mouth is in close proximity to the top of the gas cylinder, as shown in broken lines in Figure I, when charging for the occasional release of the gas m'a the usual escape-valve,(not shown,) and the month of which dipper-pipe in the then inverted position of the cylinder when discharging is in close proxinity to the then bottom of said gas-cylinder to insure the complete discharge of the anmonia from the cylinder.

Fig. I is a detail longitudinal view, part broken away and in vertical section, ot' the ammonia-gas cylinder and shows the integral branched ammonia-valve joint and the dipper-pipe secured thereto. Fig. II is a vertical detail section taken on line II II, Fig. lII, and shows the interior duplex arrangement of the valve and the charging-pipe; and Fig. III is a vertical section taken on line III llI, Fig. II, and shows the soft-metal cushion valve-seat.

Referring to the drawings, l represents the metal gas-cylinder, and 2 is the coneave valve bearer-head thereof. 3 is the screw-threaded perforate seat in the center of said concave head, in which the screw-threaded nozzle 4 of the integral branched valve-joint 5 is seated.

6 represents the arc curved dipper-pipe, the attachment screw-threaded end '7 of which is screw seated in the perforate-screw bore 8 of the nozzle 4. The nozzle 9 of said dipperpipe extends to the near vicinity of the upper side of the gas-cylinder when said cylinder is being charged, as shown in brokenlinesin Fig. I, so as to allow vent for the escape of the air or Volatile gas when it is crowded out by the charge of condensed liquefied gas, hereinafter explained. hen, however, the gas-cylinder, after reaching its destination, is being discharged of its contents, the said cylinder is inverted to the reverse side to that on which it laid when charging, and is then in the position shown in Fig. I, in which the nozzle 9 of its dipper-pipe G is in close proximity to the then bottom side of said cylinder, sothat in discharging the contents of the cylinder the said dipperpipe by its suction entirely exhausts the same. The integral branched valve-joint 5 has a duplex bore, which iS coustltuted of the main horizontal screw-threaded Valve-bore 10, the smooth-bore terminal 21, the intermediate smooth-bore 11 at the mouth of the valve, which is on line with the bores 10, 21, and 8 and connect the same, but is of a smaller diameter than either, corresponding With the inside diameter of the dipper-pipe 6, and the angle-bore 12, which runs downinto the main horizontal valve-bore 10, making together a duplex or fork bore.

13 represents an elarged screw-perforate bore at the upper end of the smooth anglebore 12 and at the same angle.

14: is a short smooth still further enlarged bore, WhlCh constitutes a gasket-seat at the upper end of and at the same angle as the two last-mentioned bores.

15 represents the conprcssor supply-pipe, (the detail attachment end of which is shown in Figs. I and 11,) the scrmv-attachnent end lb' of which engages in said screw-seat 13 in said integral branched joint. A rubber gasket 17 fits around said compre'ssor supplypipe and on said gasket-seat li. 18 represents a jam-not which is screw-mounted on said compressor supply-pipe 15 and the round stern 19 of which works downinto the gasketbore l t and compresses said rubber gasket 17, so as through the gasket to tighten the joint and through the jam-nut to tighten the compressor supply-pipe to its screw-seat.

20 represents a soft-metal gasket, preferably made of lead, the diameter of which coincides With that of the slightlyeduced diameter of the smooth terminal 2l of the main horizontal screw-bore 10 of the val vc-seat. The said soft-metal gasket is seated against the shoulder formed in the horizontal valve-seat by the reduced diameter of the intermediate bore 11 to that of 21. 23 represents the valve-stem, whose screw 24 engaes in the aforesaid screw-bore valve-seat lO. 25 is the snooth slightly-rednced extension of said valve-sten, that is seated and works in its smooth-bore seat 21, and 26 is a still further reduced ex-.

tension of said valve-stem, which worksjwithi in and without the soft-metal ga'sket 20. 27 is the terminal bevel-point of said valve-stem, and 28 is the shoulder between the extensions 25 and 26, which shoulder, when the Valve is closed, presses against the soft-metal gasket 20, (which gasket is preferahly made of lead,) so as to cfiect a gas-tight seat for the ammonia-valve stem. 29 represents the reduced neck of said valve-steu' 30 is its shoulder, which is of the same diameter as the outer periphery of its screw 24, and 31 is the wrench seat-head, which forms the outer terminal of said amnonia-valve sten and by which its right-hand screw is turnedin its seat, respectively, to open or close the valve. 37 represents the lower or valve fork of said branched valve -joint in which said screw valve-sten works, and 32 is the peripheral screw around the end of said fork, on which screw the perforate screw 33 of 'the jan-nut 34 engages. The said j am-nut perforate screw has a left-hand thread, andis thereby diverse from the valve-screw and so unaffected by its action.

35 represents a rubber gasket-ring around the valve-stem 23, and which gasket when tight pressed by the shoulder 36 of the jamnut 34, when said nut is rcrewed upon its seat, makes a gas-fight joint around the aforesaid valve-bore 10. The neck 29 of said Valvesten is seated and works during the opening and closing of the valve in the circnlar opening 38 in the end of said jam-nut.

The operation of this annonia-valve, in conjunction with the compressor supplypipe, (both of which are seated and operate within the integral branched forked valve-joint.,) is as follows: The empty gas-cylinder is placed on its side in the reverse position to that shown in Fg. I, so that the dipper-pipe, instead of presenting downward, as shown in full lines in said figure, presents Upward, as shown in brokenlines. The conpressor supply-pipe 15, a detail of which is shown in Figs. I and II, by its screw-attachment end 16 is then screw-seated` in the screw-bore 13 of the upper fork of the integral branched Valvejoint, the rubber gasket-ring 17 being placed around said pipe and on the gasket-seat l-i within said upper fork. The jam-nut 18, that is screw-mounted on said compresso' supplypipe above said fork, is screwed down until it sufiiciently compresses said rubber gasket 17 so as to form a gas-fight joint. The said compressor supply-pipe connects with the usual branch pipe, in which is located the supplyvalve and the escape-valve, the said su pply- Valve connecting with and turningon and o& the supply from the usual ammonia-refrige'- ator compressor coil. The said two lastnamed valves and compressor-coil are not shown, as they are of usual Construction, and therel'ore no novelty is claimed in tlen. At the same time they are referred to in the operation because they are operated in conjunction therewith,tthe said supply-valve to `respectively stopand'` open the supply from a free inlet through the compressor supply-` pipe 15 'and the angle-bore 12 into the main valvebore 10, so that when the aforesaid usual supply valve beneath the usual ammonia conpresso; coil (said valve and coil not shown) is opened the compressed ammonia is charged through said valve-bore and through the arc-curved dipper-pipe into the gas-oylinder 1. The said cylinder at the time of filling is laid on its reverse side to that shown in Fig. I, so as to present said dipper-pipe upward,as shown in broken lines in said figure.

Once or twice, or as many times as is deemed necessary, during the process of charging the gas-cylinder the supply-valve beneath the anmonia-coil is closed and the usual aforesaid escape-valve is opened to allow of the escape of air or volatile gas from said cylinder by the pressure of the charge. Now it will be seen that as during the process of chargin: the said arc-curved dipper-pipe is presented upward, with its tnouth in close proximity to the top of the cylinder, in the position shown in brokenlinesinFig. I, there- IOO fore the air or volatile gas which always rises to the top side of the cylinder during charging readily escapes through said dipper-pipe when the said usual supply-valve is closed and the escape-valve is opened. When the gas-cylinder is charged, the shoulder 28 of the anmonia-valve stem 23 is screwed homo to its gas-fight pressure-seat against the softmetal gasket 20, so as to eect a gas-fight joint that commands the sole outlet of the gascylinder. The compressor supply-pipe 15, that communicates with the ammonia-coil, is then disengaged from its screw-seat in the upper fork of the branched valve-joint, and a common screw-stopper may, if desired, be inserted in its place merely to keep the anglebore clean. The gas-cylinder is then ready for shipping in the form shown in full lines in Fig. I, as its branched Valve-joint and the wrench-seat of its valve-stem are in a measure protected within the concave recess 2 of said cylinder. In Fig. I, however, is shown in broken lines a modification of, the valve end of said cylinder, in which its end periphery has an inward curve 39, in which the inwardly-projecting and peripherally-expanding lug 40 of the cover 41 engages and constitutes a IIO more perfect protection of the valve. On the opposite side of said cover an inwardly-projecting lug 42 confines and clamps against said inwardly-curved edge of the cover the i square head 43 of the bolt 4i, the screw end of which bolt passes through the bolt-hole 45 in said cover and is secured in its seat, and thus fastenes the cover by the screw-nut 46. 47 represents thumb and finger holes in said cover to enable the convenient handling of the same while it is being placed to its seat and bolted to the end of said gas-cylinder. The said cover provides a complete protection from both dirt and accident for the valve. After the charged cylinder has reached its destination and it is desired to discharge the same, the gas-cylinder is laid on the same side, as shown in Fig. I, which is the reverse side to that on which it is laid while charging, so that the mouth of its are-curved dipper-pipe 6 is then, as shown in full lines, in close proximity to the bottom of said cylinder, so as to be able to completely discharge the contents of the same. The pipe connection to the usual receiver, which in the discharge is the equivalent of the compressor supply-pipo 15 used in charging, is then attached as Was said supply-pipe, and as the mouth of said arccurved dipper-pipe is in close proximity to the bottom of the cylinder the charge thereof is clean drawn.

I do not confine myself to the use of this valve and its coadjntantcharging device confined in their integral branched joint to its use in chargingand discharging ammoniacylinders, for it is evident that the device may be advantageously used in connection with other fluids, especially of all such which are charged and inclosed in vessels under pressure.
