Beit known that I, SIMON SoI-ILANGEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Filling Apparatus for Liquids, of which the following is a specification.
The invention relates more particularly to apparatus for filling barrels, kegs, and similar packages with liquid, such as beer, under pressure, and has for its objects to improve the suspending means by which the closinghead and filling-tube are carried, so as to insure the proper contact of the closing-head with the bung-hole or filling-hole of the barrel, keg, or package, to insure the positive opening-of the valve controlling the discharge of the filling-tube when the filling-tube has reached the limit of its descent, to improve the construction and operation of the appliance carrying the closing-head and the iillingtube in connection with a fluid-pressure cylinder having therein a piston by which the cross-heads carrying the closing-head and the filling-tube are raised and lowered, to utilize the waste pressure from the filling-package in actuating' the piston by which the closinghead and the filling-tube are raised and lowered, to place the control of the pressure and the liquid under a single valve, to improve the construction and operation of the valve by which the fiI'Iid-pressure and the liquid are controlled, to improve the means by which the infiow and outflow of the pressure between the filling-tank and the to be filled package is regulated and controlled, to prevent the foaming of the liquid within the package and insure the fillingI of the package with the liquid to its full capacity without waste of liquid, to furnish an intermediate controlling means for the pressure between the one controlling-valve and the to be filled package by which the Aliow of the pressure in either direction will be regulated and controlled, to furnish a relief-valve by means of which the requisite amount of pressure from outside will be supplied to prevent an explosion at the withdrawal of the filling-tube, and to improve generally the construction and operation of the several parts and mechanisms which enter into the "construction of the apparatus as a whole.

The apparatus in the construction shown has end legs or standards 1, to the tops of which are secured end supports 2, which receive and carry the filling-tank 3. made of metal or other suitable material and of a length to coaet with one or more filling appliances, the construction shown having a tank of a length sufficient to coact with three filling appliances.' The tank at one end has a fixed head 4 and at the other end has inserted therein a rim or flange 5, against which abuts a rernovable head 6 to enable access to be had to the interior of the filling-tank. rlhe end standards are connected on the front side by a plate or bar 7, the ends of which are secured to the supports by bolts 8 or otherwise.
The plate or bar 7 furnishes the support for suspending each filling apparatus, and each filling' apparatus and the suspension means therefor are of the same construction, so that the description of one will describe all. At a suitable distance apart the plate or bar 7 has secured thereto two companion bracket-plates 9, each bracket-plate having on opposite sides thereof ears 10 for the passage of bolts 11, by which each plate is secured to the plate or bar 7, and each bracket-plate has on one side edge running from its face to the ear a strengthening-flange 12 in the construction shown. Each bracket-plate has formed therewith in the arrangement shown a half box or bearing 13, the companion half box or bcaring14 of which is attached by cars 15 and bolts 16 to the bracket-plate 9, so as to make a complete journal box or bearing. Between the two cornpanion bracket-plates is located a frame 17. having straight sides and curved ends, and each end has a journal 18 to enter the journal-box of the adjoining bracket-plate, so that the frame 17 is free to rock fore and aft on its journals. Each side bar of the frame 17 has formed therewith or suitably securedl thereto a half box or bearing 19, and a companion half box or bearing 2O cooperates with the half box or bearing 19 to make a complete box or bearing. r1`he two half boxes or bearings are connected together by ears 21 on the half box or bearing 19 and ears 22 on the halfI box or bearing 21, which ears extend beneath the end edge of the side bar of the frame 17 and bolts 23. A plate 24 is located within the interior of the frame 17 and on each opposite side has a journal 25 to enter the journal box or bearings on the frame 17, so that the plate 24 is free to tip or rock endwise on its journals. This arrangement of the frame 17 and plate 24 furnishes a support which has a foreand-aft rock and an end rock by which the closing-head can be brought into position to properly coaet with the hung or other filling hole in the package in the event such bung or other filling hole is not in direct alinement with the closing-head and the filling-tube.
The plate 24 has on each side depending fianges 26, and extending down from each end of the plate 24 is ay bar 27, and each bar has outwardly projecting near its upper end an ear 28, through which passes an adjusting'- screw 29, the end of which can be set nearer to or farther from the face of the under edge of the frame 17, so as to limit the end rock of the plate 24 on its journals, and thereby limit the side swing of the bars 27 at the lower end, and consequently the side swing of the closing-head and filling-tube. rlhe lower end of each side bar 27 has on its outer face an ear 30 and on its inner face a lug 31, and the lower ends of the side bars are connected together by a cross-bar 32, which, as shown, has
a rearward projection, so as to leave a clear 9 space between the side bars at their lower ends, as shown in Fig. 6. One of the lugs 31 has extending out therefrom a head 33, projecting inwardly from which is a plate' 34, through which the filling-tube passes and by which the filling-tube is guided in its reciprocating movements.
A cross head or plate is located below thc cross head or plate 32, and this plate 35 at each end has entered therein the lower end of a-rod 36, and each rod is free to slide up and down in a thimble 37, entered into the lug 31, and each rod is fixedly attached at its lower end to the cross head or plate 35 by nuts 38 and 39 on opposite sides of the cross head or plate. Each rod 36 extends upwardly and projects above the plate 24, passing through thimbles 40, and each rod at its upper end has slipped thereon a weight 41, held in an adjusted position by a fiange or nut 41u or other suitable means, which weights, in connection with the rods and cross head or plate 35, normally act to force or carry down the cross head or plate 35 to set the closing-head inthe bungor other filling hole in the package.
The cross-head 35 on each side of its center has an enlarged portion 42 and at its center has a circular portion 43 in the construction shown, and depending from the circular portion of the cross head or plate 35 is an annularand conical shaped boss 44, terminating in an annular lip or flange 45, the inner face vof which is outwardly and upwardly inclined and receives a packing' 46, of india-rubber or other suitable material. The packing 46 is lOO entered into a groove formed in the outer face of a bushing 47, the lower end of which terminates in a ridge 48, having a curved exterior face, so as to facilitate the entering of the packing into the bung or other hole, so as to tightly close the same. The bushing 48 in its interior face has a series of slots or passagesr49 extending from the top to the bottom of the bushing, and the bushing on the exterior around its upper end has a thread, by means of which it is screw-threaded into an opening therefor in the circular portion of the cross head or plate 35. rlhe slots or passages 49 at their upper end open into an annular chamber 50, from which on one side in the enlarged portion of the cross head or bar 35 leads a passage 51, through which passage and the chamber and the slots or passages fluid-pressure can be admitted into and escape from the to-be-filled package.
The filling-tube 52 for the liquid passes through the circular portion of the cross head or plate 35 and is surrounded by the annular chamber 50 and is guided in its reciprocating movements by the bushing 47, so that the illing-tube will have a direct line movement and a iirm support in being entered into and withdrawn from the barrel and will not wear on its exterior face in its operation. The fillingtube passes through a cross-wall 53 of an annular iiange or rim 53, in the chamber 54 of which is a packing 55, compressed by aglandA or follower 56, threaded into the end of the annular rim or flange 53, so that by advancing the gland or follower the packing will be forced against the exterior face of the lillingtube and made a close tight joint against the escape of pressure and liquid around the filling-tube` The upper end of the liquid-filling tube 52 is threaded into an annular flange orrim 57 on the Linder side of a head 58, which head on its upper side has an annular flange or rim 59, into which is threaded the lower end of a piston-rod 60, and the piston-rod 60 at its upper end has a piston 61, which operates in a cylinder 62, which cylinder atits extreme upper end is closed by a cap 63 and a packing 64, so as to be tight against the escape of fluid-pressure. The lower end of the cylinder 62 is threaded into an annular ange or rim 65, attached to the plate 24 by screws 66 or otherwise. Depending' from the under side of the plate 24 is an annular wall or boss 67, having' a cross-plate 68, through which the piston-rod passes, and above the cross-wall 68 is a chamber 69, which opens into the lower end of the cylinder 62, and below the crosswall 68 is a chamber 70, into which is threaded a thimble or bearing71, furnishingaguide for the piston-rod 60. The annular wall 67 on one side has a boss 72, in which and in the plate 24 is a passage 73, which' opensinto the lower end of the cylinder 62 for admitting fluid-pressu re into the cylinder below the piston. The piston-rod passes through a thimble or bearing 74, threaded into an annular flange or rim 7 5 on a cross-head 75, and the cross bar or head at each end has a socket 76, through which sockets the rods 36 pass, and the cross head or bar is locked in position on the rods 36 by bolts 77 or otherwise, so as to be adjustable on the rod 36 for the cross head or bar to furnish a stop by striking against the end of the thimble or bearing-box 71, as shown in Fig. 2.
' The liquid-filling tube 52 at its lower end in the arrangement shown is cut away, so as to form a recess 7,8, into which is entered the valve by which the discharge of the liquid is controlled. The valve shown consists of a plug' 79, having a tapered exterior face to enter the lower end of the liquid-filling tube, and a body terminating in a threaded stem 81, leaving a shoulder at the base ot' the coneshaped plug, against which shoulder a plate 82 abuts, and below the plate 82 is a packing 83 ofany suitable material cylindrical in crosssection and held in a groove formed between the plate and a securing head or nut 84 threaded onto the stem 81, which packing allows of the necessary yield to insure a tight closing of the discharge end of the filling-tube for the liquid when the valve is drawn into the end of the filling-tube. The valve is threaded onto the lower end of a rod 85, the upper end of which is threaded into a pendant 86, suspended from a pivot 87 in the slot 88 of an arm 89, which arm and pendant are located in a chamber 58, formed within the head 58, as shown in Figs. 15 and 16. The arm 89 is ixedly attached to a cross-shaft 90, which shaft is supported in journal-boxes in the side walls of the head 58, each ljournal-box consisting of a hollow plug 91, threaded into the side wall of the lhead 58 and having' in its chamber 92 a packing 93, compressed by a gland or follower 94, threaded into the end of the hollow plug', so that a tight joint is formed around the shaft 90 against the escape of liquid-pressure. Each end of the shaft 90 projects beyond its journal box or bearing' and has secured thereto by a key or spline 95 the arm 96 of a forked lever 97, which lever at its outer or free end 98, as shown, is spread apart, so as to leave an open space, and, as shown, the forked lever is made in two parts, but could be made in a single piece, if so desired. rlhe forked lever 97 is held normally depressed by a roller 99, engaging with its upper edge, which roller is carried by springarms 100, each spring-arm having a coil 101, which encircles a stud 102, projecting out from the side wall of the head 58, and the short end 103 of each spring-arm outside of the coil engages with a stud 104, projecting out from the side wall of the head 58, so that with the upward movement of the forked lever 97 the spring-a rms will be put under a tension which serves to return the forked lever to normal position with the removal of the force by IOC TIO
which the lever was raised. The forked lever l when in normal position and held in that position, as shown in Fig. 14, rocks the shaft 90 and raises the outer or free end of the arm 89, raising the pendant 86, and with it the rod 85, drawing the valve at the lower end of the discharge-tube 52 tightly into place against the end of the tube and shutting' oill the flow ot' liquid through the tube. The initial descent of the cross-heads carries down the closing-head and the filling tube 52, and the Afarther descent o'tl the filling-tube through the downward travel ot' the piston 61 carries with it the head 58 and the parts connected therewith. The downward movement of the lever 97 continues with the downward movement of the head 58, and when the lever has reached a point where its under face contacts the end of a pin or stud 105, extending up from the lug or head 33, the farther descent of the lilling-tube and the head 58 raises the outer end of the lever 97 and rocks the shaft`90, bring'- ing the parts into position shown in Fig. 15, by which the outer or free end of the arm 89 is carried down, carrying with it the pendant 86, forcing the rod 85 down and carryingl the closing-valve away from the end of thedischarge-tube 52, as shown in Fig. 15, leaving the end o'tl the tube open for the free discharge of the liquid into the package. r1`his opening of the closing-valve for the liquid-iilling tube does not occur until the iilling-tube has entered the package and nearly reached the limit of its downward movement Jfor the continued, downward movement to the limit to act and raise the free end of the lever 97 and open the valve, as just described.
The upper end of the cylinder 62 at a point above the limit of the upward travel ot' the piston 61 has entered thereinto a 4pipe 106, connected by an elbow-coupling 107 with a short pipe 108, which in turn is connected byv an elbow-coupling 109 with a pipe 11.0, the lower end ol'l which enters an elbow-coupling 111 on the end of a connecting-pipe 112, the other end of which enters an elbow-coupling 113 on the end of a short pipe 114, entered into a ilange or boss on the main controllingvalve. The shell or casing of the main controlling-valve has a iiange on the opposite side to the pipe 114, into which is entered the end of a pipe 115, connected by an elbowcoupling 116 with a short pipe 117, entered into an elbow-coupling 118, into which coupling is entered the lower end of a pipe 119, the upper end of which enters a coupling 120, connected with a coupling 121, from which a pipe 122 leads to an elbow-coupling 123 on the end of a short pipe 124 in communication with the passage 73 for discharging lluidpressure into the cylinder 62 below the piston 61 of said cylinder. The pipe 110 constitutes a lead-pipe between the main controlling-valve for the fluid-pressure and the top of the cylinder, and the pipe 119 constitutes `a lead-pipe between the main controllingvalve and the lower end of the fluid-pressure cylinder, and the intermediate pipes and elbow-couplings serve only to bring the leadpipes into proper relation with the main controlling-valve for the position of the valve, and it will be understood that the lead-pipes and the valve can be located and arranged in other ways and so as to dispense with some ofthe elbow-couplings and intermediate pipes forv making the connection between the leadpipes, the valve, and the cylinder.
A fluid-pressure-supply pipe 125, leading from any suitable source o't` fluid-pressure, is connected at its end with a tube 126, communicating with the upper portion of the fillingtank for the liquid, as shown in Figs. 4and 5. The iluid-pressure-supply pipe 125 has therein a coupling 127, to which is connected one end of a hose 128, the other end of which is connected by a coupling 129 with a tube 130, the lower end of which is connected by an elbow-coupling131 with a short tube 132, which in turn is connected by an elbow-coupling 133 with a tube 134, the lower end of which is entered into a boss or wall135 on the upper side ot` the shell or casing 136 of the main valve, and it will be understood that the tube 134 is the lead-tube and the elbow-couplings and intervening tubes are for the purpose of connecting the lead-tube with the hose, arising .from the location ot' the main valve in the arrangement shown. The main valve has a' shell or casing136, having at one end atlange 137 and a closed wall 138, extending out from which is a threaded stem 139, by means of which the valve is attached to one of the side bars 27 of the frame carrying the closing-head and the filling-tube, so that the valve is within easy reach of the operator. The opposite end of the shell or casing 136 has a ilange 140, adjacent to which is a plate 141, connected with the flange by screws 142, the heads 143 ot' which are countersunk in the face ot' the plate 141 in the arrangement shown. r1`he plate 141 encircles a neck 144 at one end of the valveplug' 145, the body of which is tapered and enters a tapered chamber 146 in the shell or casing 136, as shown in Fig. 7. The shell or casing 136 ot' the main valve has on one side a boss or wall 147, into which is entered the pipe 114, and on the opposite side the shell or casing 136 has a boss or wall 148, into which is entered the pipe 115, and the underside or bottom of the shell or casing136 has a boss or wall135, which, as shown, does not have any tube or pipe connected therewith,but is open to the air. The shell or casing 136 has therein a port 149, which communicates with the pipe or tube 114 at one end, and its other end by the turning of the valve-plug 145 can be brought into 'communication with a curved passage 150 in the valve-plug, and the shell or casing136 has therein a port 151, which communicates with the pipe or tube 115 at one IOO IOS
end,and its other end by turning the valve- The shell or casing 136 has therein a port153,
which communicates at one end with the pipe or tube 134 and can be brought into communication atits other end witha passage 150 oi' the valve-plug', and the shell or casing 136 has therein a port 154, which at one end opens into the chamber of the boss or wall on the underside of the shell or casing, and its other end can be brought into communication with the passage 152 of the valve-plug. Theshell or casing 136 has therein a longitudinal passage 155, communicating at one end with the port 153 and communicating at its other end with a passag'e 156, inwardly leading toward the valve-plug 145 and in communication with a passage 157 on the exterior oi' the valveplug, as shown in Figs. 7 and 9, and the shell or casing 136 has therein a longitudinal passage 158, one end of which communicates with the port 154 and at its other end is in communication with a passage 159, leading inwardly to the plug-valve 145 and in communication with a passage 160 in the exterior. of the plug-Valve, as shown in Fig. 9. l1t will be seen that the ports 153 and 154 have communication with the passages 150 and 152 in the valve-plug' 145 and also with the passages 157 and 160 in the valve-plug and that the ports 149 and 151 have communication with the passages 150 and 152 and can be brought into communication with the ports 153 and 154 by turning the plug-Valve and that when the passages 150 and 152 are brought into communication with the ports 149 and 153 and 151 and 154 the passages 157 and 160 are also in communication with the ports 153 and 154, making the main valve, in effect, an eight-way valve, for a purpose hereinafter described. The shell or casing 136 has therein a port 161, which can be broughtinto communication with the passage 157 by turning' the valve-plug 145, as shown in Fig. 9, and this port is in communication with a nipple 162,attached to which is one end of a hose 163. The shell or casing 136 has therein a port 164, which can be brought into communication with the passage 160 by turning the valveplug 145 as shown in Fig. 9, and this port is in communication with a nipple 165, having attached 'thereto one end oi' a hose 166, so that when communication is established between the passage 157 and the port 153, Huid-pressure communication is established between the port 164 and the port 154, fluid-pressure from the hose 166 will discharge into the air.
The top of the filling-tank 3 has entered thereinto anipple 167, to which is attached one end of a hose 168, the other end of which is attached by a coupling 169 to the upper end of a pipe or tube 170, terminating at its lower end in a turned portion 171, which is connected to one end of a three-way coupling 172,
as shown in Fig. 11. The upper end of the three-way coupling 172 has entered thereinto a hollow stem 173, depending from the center of a plate or disk 174, having an annular flange or rim 175 around its periphery, into which is threaded the lower end oi' a cylinder 176, the Lipper end of which cylinder is threaded into an annular iiangeor rim 177 around the periphery or' a plate or disk 178, extending out from the center oi' which is a nipple 179, to which is attached the end of the hose 163, as shown in Figs. 1, 2, 3, 4and 11. The bottom plate or disk 174 on one side has therein a passage 180, which opens into the lower end of the cylinder 17 6, and this passage is connected by a nipple 181 with the hose 166, as shown in Figs. 1, 2, 3, and 11. The cylinder 176 has located and operating therein a piston 182, consisting, as shown, of two cupleathers 182 and 183, clamped between plates 184 and 185 by nuts 186 on the threaded end of a piston rod or stem 187, which piston-rod passes through the chamber 188 ofthe stem 173, in which chamber is a packing' 189, compressed around the piston rod or stem by a gland or follower 190 encircling the'piston rod o1' stem' and threaded into the hollow stem 173, so as to make a tight joint around the piston rod or stem against the escape of fluid-pressure.
rThe piston rod or stem at its lower end has fixed thereto a valve consisting oi' a disk 191, of rubber, leather, or other suitable material, carried by a disk or plate 192, having a peripheral rim or iiange encircling the valvedisk and held in place on the piston rod or stem by a nut 193, so that the valve can be properly adjusted for use. The valve at the lower end of the piston' rod or stem 187 closes the lower end of a hollow piston rod or stem 194, the upper end of which is threaded into an end oi' the three-way coupling 17 2, as shown in Fig. 11. This hollow piston rod or stem 194 carries at its lower end a valve consisting, as shown, of a cup-leather 195, held between plates or disks 196 and 197, and, as shown, the disk 197 has a flange or rim 198, with an interior screw-thread, by means of which the valve is att-ached to the piston rod or stem 194, and the two plates or disks 196 and 197, with the cup-leather between them, areunited one to the other by screws 199 in the arrangement shown. The piston of the hollow stem 194 is located and operates in a cylinder' 200, preferably made of glass or other transparent material. rl`he cylinder 200 is held between an upper plate or disk and a lower plate or disk, and the upper plate or disk 201 has a depending peripheral rim or flange 202 encircling the upper end of the cylinder, and between the upper end of the cylinder and the IOO IIO
under face o't' the plate or disk 201 is a pack- I ing 203, of any suitable material. The upper plate or disk 201 has extending up therefrom a neck 204, in which the hollow piston rod or stem 194 reciprocates, and the neck 204 has an exterior screw-thread on which is entered a cap 205, which incloses a packing' 206, which packing' is compressed by advancing the cap so as to make a tight joint around the hollow piston rod or stem against the escape of fluidpressure. The lower plate or disk 207 of the cylinder 200 has a peripheral rim or flange 208, into which is entered the lower end of the cylinder 200, and between the end of the cylinder and the upper face of the disk or plate is a packing 209, of any suitable material. ',lihe two disks or plates 201 and 207 are tied together by rods 207, extending up from the lower plate or disk and passing' throug'h the upper plate or disk and receivingon their ends wing-nuts 207", by means of which rods and nuts the plates or disks are drawn toward each other, so as to compress the packing' 202 and 209 at each end of the cylinder, making' a tight joint for the cylinder against the escape of fluid-pressure.
The lower disk or plate 207 has extending downwardly therefrom a neck 210, in which is a passage 211, communicating at its upper end with the interior of the cylinder 200 and 'communicating at its lower end with the lateral passage 51 within the cross head or bar 35. The passage 211 is closed at its upper end by a valve coacting with a seat 212 around the passage in the bottom plate or disk 207, and, as shown, the valve consists of a disk 213, of rubber, leather, or other suitable material, held by a plate 214, having' a peripheral rim or flange within which the valve-disk is located, and the disk or plate 214 is held bctween nuts 215 on a valve-stem 216, extending' down through the passage 211 and encircled bya coiled spring 217, the l'ower end of which spring' rests on a cross-pin 218 and tends to hold the valve in its closed position. The bottom of the cross head or bar 35 has a rim or ange 219 surrounding' a chamber 219, extending' into the enlarged portion 42 o'f the cross head or bar, in which chamber and around the valve-stein 216 is a plate or disk 220, beneath which is a packing 221 in the chamber, which packing' is compressed around the stem by a gland or follower 222, threaded into the annular wall or rim 219, so that when the packing is compressed a tight joint will be formed around the stem 216 against the escape of fluid-pressure.
The head 58 on one side has a port 223, encircled by a rim 224, into which is entered a coupling 225 on the end of a hose 226, the other end of which hose is coupled to a nipple of a valve 227, entered into the bottom of the filling-tank, so that with the opening of the valve 227 liquid can flow from the filling-tank into the chamber of the head 58 and discharge through the filling-tube 52 into the package when the valve controlling the discharge end of the filling-tube has been opened by the raising of the lifting-lever 97, as hereinbefore described.
At one end of the filling-tank on the under side is entered a bushing 228, to which is connected a valve 229, the inlet side ofv which has entered thereinto a short tube 230, extending up from a plate 231, which is connected to a plate 232 by rods 233 for the plates to retain between them a cylinder 234, of g'lass or other transparent material and constituting a sightglass, and from the bottom of the plate 232 extends a short tube or nipple 235, to which by means of a coupling 236 is attached a hose 237, leading' to the supply ifor the beer or other liquid, so that by opening the valve 229 the beer or other liquid is free to flow into the filling-tank 3 to be taken therefrom by the supply-hose foreach lilling apparatus and transferred to the package to be filled by means of the filling-tube.
The cylinder 200 has located in its bottom a vent-valve 'for supplying' outside pressure to lill the vacuum in the cylinder as the liquid vliows out therefrom with the withdrawal of the filling-tube 'from the package. This vent-valve, as shown, consists of a rubber tube 238, slipped onto the end of a hollow stem 239, which stem has an exterior thread vfor securing it in the bottom 207 of the cylinder 200, the stem having at its outer end a thumb-head 240, by means of which it can be advanced and receded in the head 207, and extending' through the stem and the head is a vent-hole 241, which allows pressure from the outside to act and open the walls of the tube 238 above the end of the stem, permitting air under atmospheric pressure to flow into the IOO cylinder 200 and lill the vacuum created by the withdrawal of the liquid, and thereby prevent explosive action with the withdrawal of the filling-tube. lt will be understood that when Huid-pressure is passing' through the cylinder it will act and bring' together the end of the tube above the end of the stem, making' Y a tight joint against the admission of outside air, and with the admission of liquid into the cylinder 200 the liquid also serves to hold the end of the rubber tube tightly closed, so that outside air cannot enter until a vacuum is created by the outliow of the liquid from the cylinder in the withdrawal of the filling-tube 'from the package.
The neck 144 of valve-plug 145 has extending out therefrom a squared end 242, onto whchis entered the socket 243 of a handle 244, and, as shown, the handle is held on the squared end 242 by a washer 245, abutting' against the end face of the socket 243 and held in place by a screw 246, ventered into the squared end or in any other suitable manner. The passages 150 and 152 and the passage 157 and 158 are so arranged, preferably, that when the handle is vertical the passages 150 and 152 are out of communication with the ports 149 and 153 for the passage 150 and the ports 151 and 154 for the passage 152, closing the tlow of fluid-pressure through these ports IIO and passages, and the passage 155 and 156 is out ot' communication with the passage 157, and the passage 158 and 159 is out ot' communication with the passage 160, shutting off the iiow of fluid-pressure through these several passages.
The handle 244 when in normal position stands vertical, or nearly so, in the arrangement shown, and with the handle 244-normal the valve-plug is turned to shut off communication between the passages of the valveplug and the ports in the shell or casing. The movement of the handle 244 forward to a slight extent turns the valve-plug 145 and brings the passage 150 into communication with-the ports 149 and 153, allowing pressure to flow from the filling-tank through the hose 128, pipe or tube 134, and pipe or tube 110 into the upper end or' the cylinder 62 above the piston, and at the same time the passage 152 is brought into communication with the ports 151 and 154, venting pressure from the cylinder 62 below the piston 61 by means of the pipe 119 to the atmosphere for the pressure above the piston 61 to force down th'e closing-head suliciently to close the bung'or other lilling-hole in the package. Thisinitial turning ot' the valve-plug 145 brings the passage 157 into position to establish communication between the passage 155 and 156 and the port 161 'for the pressure from the pipe or tube 134 to iiow through the hose 163 into the top of the cylinder 176 above the piston in said cylinder, forcing the piston down, and with it the stem 187, opening the valve at the lower end of the hollow piston rod or stem 194, allowing' pressure to flow from the pipe or tube 170 through the hollow piston stem or rod 194 into the cylinder 260 below the piston in said cylinder, and the pressure so entering the cylinder 20() can flow through the passage 211, the valve ot' such passage being opened from the contacto]c the end of the stem 216 with the package into the passage 51, and thechamber 50 to enter through the slots or passages 49, the package to be filled, equalizing the pressure between the iilling-tank and the to-be-iilled package, so that when the closing-valve of the filling-tube is opened the liquid can flow into the package Linder an equalized pressure within the package and the lilling-tan k. The initial turning of the valveplug 145 brings the passage 160 into position to establish communication between the passage 158 and 159 and the port 164, allowing pressure below the piston in thecylinder 176 to escape through the passage 185 and hose 166 and discharge at the opening of the wall or boss 135 to the atmosphere. This initial turning of the valve-plug 145 for admitting and venting pressure as just described allows the sealing-head to descend and close the bung or other filling hole in the to-be-filled package, so that the Huid-pressure can enter the package through the slots or passages 49 to equalize the pressure between the filling-tank and package. The further movement forward ot' the handle 244 carries the passage 150 into full communication with the ports 149 and 153 and carries the passage 152 into full communication with the ports 151 and 154, as shown in Figs. 8 and 9. The pressure in the cylinder 62 below the piston 61 will now eX- haust through the ports 157 and 154 and the passage 152, so that the pressure admitted into the cylinder 62 above the piston 61 through the ports 149 and 153 and passage 150 will act and move the piston 61 downwardly in the cylinder, and such downward movement of the piston 61 through the piston rod or stem 60 forces down the head '58, and with it the filling-tube, for the lower end of the iilling-tube to pass downwardly into the to-be-lilled package, and when the head 58 in its descent has reached a point where the lever 97 engages the stop 105 the further descent o'f the lilling-tube 52 opens the closingvalve at its end, allowing the beer to discharge into the package. The full opening' of the passages 150 and 152 leaves still open the passages 157 and 160, so that the fluid-pressure can flow through the passage 155 and 156, passage 157, and port161 to enter the hose 163 and pass into the top of the cylinder 176, holding the piston in said cylinder down and main- 9 taining the valve at the end of the hollow stem or piston 194 open, and at the same time the passage 160 maintains communication between the passage 158 and 159 and the port 154 vfor venting presssure from below the piston in the cylinder 176 through the hose 166 to the atmosphere.
The iniiow of the liquid into the package as the liquid rises forces out the Huid-pressure in the package, and such pressure ilows back through the slots or passages 49 into thc chamber 56 and out from the chamber 50 through the passages 51 and 211 into the bottom o1' the cylinder 200 and flows through the hollow stem or piston-rod 194 into the pipe 170 to return to the filling-tank. The liquid when the pressure has been expelled completely from the package by the liquid lilling the package follows the lpressure and flows into the cylinder 200 through the slots or passages 49, chamber 50, passages 51, and passage 211, and when the liquid has entered the cylinder to a point where it reaches the face of the valve closing the lower end of the hollow stem or pistonrod 194 a further forward turning of the handle 244 'carries the valve-plug 145 into position to bring the passage 152 into communication with the ports 149 and 154, venting the pressure in the cylinder 62 above the piston 61 to the atmosphere. At the same time the passage 150 is brought into communication with the ports 151 and 153,- admitting pressure below the piston 61 in the cylinder 62 for the admitted pressure below the piston 16 in the cylinder 62 to act and initially IOO raise the piston in such cylinder, closing the valve at the lower end of the lilling-tube by the throwing down of the lever 97 from the action of the spring-arms 100, and shutting off the flow of liquid into the filled package, so that the liquid can only rise in the cylinder 200 to the height of the piston in the cylinder 200, and it is to be understood that the piston in the cylinder 200 can be adjusted higher or lower and when adjusted remains in the position in which it is adjusted, forming an abutment against the flow of liquid into the cylinder 200 above the piston, maintaining an equalized pressure back of such piston. A still further forward movement of the handle 244 turns the valve-plug 145 into a position to establish full communication between the passage 150 and the ports 151 and 153, by which the pressure above the piston 61 in the cylinder 62 is fully vented to the atmosphere, and at the same time the passage 152 is brought into full communication with the ports 149 and port 154 for pressure to iiow into the lower end of the cylinder 62 and raise the piston 61, withdrawing the filling tube from the package. The upward movement of the lilling-tube continues until the annular flange abuts against the thimble 74, after which the continued upward movement of the piston 61 raises both the filling-tube and the closinghead in unison until the closing-head is clear of the package, at which time the liquid contained inthe cylinder 200 has liowed back into the package, and the amount of liquid contained in the cylinder 200 below the -piston therein should be suflicient to completely lill the package, for which purpose the position of the piston in the cylinder 200 should be adjusted accordingly. The further advance of the handle 244 to initially open communication between the ports 151 and 153 and the passage 150 to vent pressure from above the piston 61 and to initially open communication between the ports 159 and 154 and the passage 152 to admit pressure below the piston 61 to initially raise the filling-tube opens communication between the passage 160, the port 161, and the passage 158 and 159 to vent pressure from above the piston in the cylinder 176 for the pressure below the piston in said cylinder to act and raise the piston, closing the valve at the lowerendof the hollow stem or piston-rod 194 and shutting off the flow of pressure and liquid into the hollow stem or piston-rod 194, so that the liquid will be held in the space of the cylinder 200 below the piston in such cylinder. The further turning of the handle to bring the valve-plug 145 into position for establishing a full communication betweenthe ports 151 and 153 and the passage 150 and to establish full communication between the ports 149 and 154 and the passage 152 brings the passage 157 into full communication with the port 164and the pasinto the cylinder 176 below the piston in said cylinder, the pressure entering through the port 164 and hose 166 and port 135 into the chamber of the cylinder 176 below the piston of said cylinder, and at the same time the passage 160 is brought in full communication with the port 161 and the passage 158 and 159 to vent the pressure above the piston in the cylinder 176 to the atmosphere, the pressure entering' the port 161 through the hose 163, attached to the nipple 179 at the top of the cylinder. The handle 244 after the full return of the closing-head and filling-tube for the liquid is turned back to normal position, closing the several ports and passages of the main valve and bringing the valve and the parts into position for operation with thel next packageto be filled by again advancing the handle, as already described.
The arrangement shown has between the end legs or standards 1 a platform 247, and to this platform is secured a series of standards or uprights 248, arranged in pairs, one pair for each lilling apparatus. The pair of standards have journaled therein axles 249, on which are supporting-wheels 250, each havng a beveled face, on which wheels is supported the barrel, keg', or other package 251, havingabungor other lilling hole 252,through which enters the lilling-tube 52 and which is to be closed by the closing-head when the package is to be filled with liquid.
The operation is as follows: The package 251 to be lilled is placed on the wheels 25() with the bung orother filling hole at the top, as shown on the left hand of Fig. 1. The closing-head and the lilling-tube are raised, as shown on the left hand of Fig. 1, and the handle 244 is in normal position, so as to close all the ports and passages of the main controlling-valve. After the package is placed in position the handle 244 is turned to initially open communication between the ports 149 and 153 and the passage 150 to admit pressure to the cylinder 62 at its upper end above vthe piston 61 and to open communication between the ports 151 and 154 and the passage 152 to vent pressure from the lower end of the cylinder 62 below the piston 61, which allows the closing-head to descend and close the bung or other filling hole in the package. This main controlling-valve after it has been initially opened to cause the lilling-tube and closing-head to descend sufficiently for the closing-head to seal the bung orother filling' hole by a slight backward turning of the valveplug brings the ports into the position shown A in Fig. 10, in which position pressure is shut olil from the cylinder of the filling-tube, but is free to flow into the package for equalizing the pressure, as at the same time the passage 157 is brought into position to establish communication between the port 161 and the passage and 156 for pressure to flow through sage 155 and 156 forfully admittingpressure fthe hose 163 into the cylinder 176 above the piston in said cylinder and to establish communication between the passage 160, the port 164, and the passage 158 and 159 to vent pressure through the hose 166 from the lower end of the cylinder 176 below the piston in said cylinder. The downward movement of' the piston in the cylinder 17 6 carries the valve at the lower end of the piston-rod 187 away from the lower end of the hollow stem or piston-rod 194, allowing pressure from the pipe or tube 170 to flow through the hollow stem or piston-rod 194 and enter the to-be-filled package through the passage 211, the passage 51, the chamber 50, and the slots or passages 49 to equalize the pressure between the fillingtank and the package. rlhe further movement forward of' the handle 244 to establish f'ull communication between the ports 149 and 153 and the passage 156 admits full pressure to the upper end of the cylinder 62 back ofl the piston 61 and at the same time establishing full communication between the ports 151 and 154 and the passage 152 to vent the pressure from the lower end of' the cylinder 62 below the piston 61 for the pressure above the piston 61 to carry down the piston-rod 60, head 58, and filling-tube 52, entering the lower end of the filling-tube into the to-be-filled package. The Contact of the lever 97 with the stop 105 as the filling-tube nearly reaches the limit of its descent opens the valve at the lower end of the filling-tube, and with the conclusion ofl the descent of' the filling-tube to its limit the valve at its lower end is fully opened 'for the liquid to discharge into the package. The passage 157 is still in communication with the port 161, and the passage 155 and 156 and the passage 166 is still in communication with the port 164 and the passage 158 and 159, so that the valve closing the lower end of the hollow stem or piston rod 194 is held open, allowing' the pressure which is forced out from the package by the admission of' the liquid to flow back through the slots or passages 49, chamber 50, passage 51, passage 211, hollow stem or piston-rod 194, and pipe or tube 170 into the top of' the tank, thus maintaining the regulated pressure in the tank without the admission of additional pressure from the source of' supply. The continued flow of the liquid into the package gradually fills the package, and when filled with the liquid the pressure will be completely f'orced -out, and the further supply of the liquid will f'ollow the pressure through the slots or passages 49, chamber 50, passage 51, and passage 211 and enter the chamber of the cylinder 200 below the piston in said cylinder. The liquid is allowed to How into the cylinder 20() until it reaches the under face of the valve for the lower end of' the hollow stem or piston-rod 194, at which time the operator turns the handle 244 forward to initially establish communication between the ports 151 and 153, admitting pressure to the cylinder V62 beloy7 the piston 61, and at the same time establish communication between the ports 149 and 154 and the passage 152 for venting pressure from the upper end of' the cylinder 62 above the piston 61, so that the pressure below the piston 61 will act and initially raise the fillingtube, releasing' the contact ofl the lever 97 with the stop 105 for the spring-arms to act and close the valve at the lower end of' the fillingtube, shutting off the supply of liquid. initial establishment of Vcommunication between the ports 151 and 153 and passage 150 and between the ports 149 and 154 and the passage 152 establishes communication between the passage 157, the port 164, and the passage 155 and 156, admitting pressure to the lower end of' the cylinder 176 below the piston in said cylinder and at the same time establishing communication between the passage 160, the port 164, and the passage 158 159, venting pressure from the cylinder 17 6 above the piston in said cylinder for the pressure below the piston in the cylinder 176 to act and raise the piston and close the valve at the lower end of the hollow stem or piston-rod, shutting o6? the flow of pressure and liquid into the hollow stem or piston-rod. The establishment of' f'ull communication between the ports 151 and 153 and passage 150 and between the ports 149 and 154 and the passage 152 still n'iaintains communication between the passage 157, port 164, and passage 155 and 156 and between the passage 160, port 161, and passage 158 and 159 f'or the admitted pressure below the piston in the cylinder 176 to hold closed the valve at the lower end of' the hollow stem or pistonrod 194. rlhe pressure admitted to the lower end of' the cylinder 62 below the piston 610011- tinues to act, when full' communication is established between the ports 149 and 154 and passage 152 and raise the piston 61, and such upward movement of the piston 61 carries with it the piston-rod and its head 58, and with the contact of the head 58 with the crosshead 75 the further upward movement of the piston 61 raises the closing-head, with the filling-tube, clear of the filled package. The closing -head can be swung backward out of' the way for the insertion of` the bung by rocking the f'rame 17 on its end journals, and after the bung has been inserted the filled package can be rolled off from the supporting-wheels and a new package placed in position, and when in position the handle 244 can be again moved to cause the closing-head to descend and to admit pressure to the package to equalize the pressure between the fillingtank and package and to cause the filling-tube to descend and open the valve at its lower end and when the package is filled cause the filling-tube to initially rise, closing the valve at its lower end, and to close the pressure-passage between the filling-tank and the filled package and to raise the filling-tube and closing-head out of' and clear of' the package. A new package is then placed in position,'and these oper- The lOO

ations are continued until the supply of' liquid is exhausted or until the required number of' packages have been filled.
The port 153 is the main inlet-port, as it is always in communication with the source of' pressure-supply, and the port 154 is the main outlet or discharge port, as it is always open to the air. r1`he ports 149 and 151 are intermediate of' the ports 153 and 154, and each i port performs `the oliice of a supply andA eX- haust port in itself'Y-that is, pressure is free to iow in either direction through these ports, the direction of fiow depending on the relation of the passages 150 and 152 to the ports 153 and 154 as to whether the ports 149 and 151 are induction or ed uction ports. The passage 155 and 156 is an inlet-passage through its communication with theinlet-port 153, and the passage 158 and 159 is an outlet-passag'e through its connection with the port 154, while the ports 161 and 164 are both supply and exhaust ports, according' as to their connection with the passages 157 and 160 and the connection of the passages 157 and 160 with the passage 155 and 156 and the passage 158 and 159. The several positions of the ports and passages in themain controlling-valve are illustrated in the outline ligures from 17 to 26, both inclusive. Figs. 17 and 18 are companion ones and show the normal position ofl the plugvalve, in which position the ports 149, 151, 153, and 154 are closed against communication with the passages 150 and 152 and the ports 161 and 164 are closed against communication through the passages 157 and 160 with the passages 155 and 156 and 158 and 159 --that is to say, the main controlling-valve is closed against the flow of' pressure. Figs. 19 and 2O are companion ones and show the initial turning of the valve-plug 145 which brings into communication the ports 149 and 153 and the passage 150 and the ports 151 and 154 and the passage 152 and also brings into communication the passage 155 and 156, the port 161 and the passage 157, and the passage 158 and 159, the passage 160, and the port 164. Figs. 21 and 22 are com panion ones and show the turning of the valve-plug 145 to bring into full communication the ports 149 and 153 and the passage 150 and the ports 151 and 154 and the passage 152 and also maintaining communication between the passage' 155 and 156, ports 161 and passage 157, and passage 158 and 159, port 164, and passage 160. Figs. 23 and 24 are companion ones and show the further turning of the valve-plug to initially open communication between the ports 151 and 153 and the passage 150 and the ports 149 and 154 and the passage 152 and at the same time opening communication between the passage 155 and 156, port 164, and passage 157 and opening communication between the passage 158 and 159, port 161, and passage 160. Figs. 25 and 26 are companion ones, showing the valve-plug turned to bring into f'ull communication the ports 151 and 153 and passage 150 and the ports 149 and 154 and the passage 152 and maintaining the passage 155 and 156, port 164, and passage 157 in communication and the passage 158 and 159, port 161, and passage 160 in communication. It will be understood that the turning of' the plugvalve is, in efl'ect,contin uous,as theinitial communication for admitting pressure to the package is effected almost instantly with the passage of' the valve-plug to its full position, (shown in Figs. 21 and 22,) and the initial communication ofl the ports and passages (shown l in Figs. 23 and 24) is effected with the turning of the valve-plug to the full position, (shown in Figs. 25 and 26,) and the return movement of the Valve-plug is a single movement back to the normal position, (shown in Figs. 17 and 18,) shutting ofi the flow ofl pressure.
The pressure returned to the filling-tank from the to-be-filled package as the liquid Hows into the package is utilized in furnishing the requisite amount of' pressure for operating the filling-tube and for equalizing the pressure between the filling-tank and the tobe-filled package, such return pressure taking the place of' the pressure vented in the operation of' the closing-head and the filling-tube and the piston in the cylinder 176, and with this arrangement the pressure returned to the filling-tank from the package is made use of instead of being' vented, as isthe practice in other filling apparatus for liquids. The weights 41, in connection with the weight of' the rods, cross-heads, filling-tube, and closinghead, is suliicient to initially carry downward the closing-head for the closing-head to enfer l and seal the bung' or other filling hole in the package, the filling-tube being carried down by the initial pressure back of the piston 61, so that its end will project into the package to be filled as the bung or other filling hole is sealed by theclosing-head. rlhe pipe or tube 170 serves as a supply-pipe to admit pressure to the cylinder 200 and also as a returnpipe for the pressure forced vfrom the package by the liquid. rl`he cylinder 176, with its piston, furnishes the means f'or controlling the valve by which pressure is inducted into the cylinder 200 and by which pressure is educted from said cylinder, and the cylinder 200 'furnishcs a receiver for the pressure in traveling both ways and also as a receptacle for containing a suflicient quantity of liquid to replace the liquid in the package displaced by the filling-tube. The cylinder 176, with its piston, is a controlling-cylinder for admitting and venting pressure to the cylinder 200, which cylinder is a pressure-cylinder by which pressure is supplied to the package to be lilled and receives the pressure forced from the package by the inflow of' the liquid thereinto. It will be seen that the control of' pressure for operating the filling-tube and the control of' pressure for equalizing the pressure between the filling-tank and the to-be-iilled package are IIO IIS
both under one valve, such valve constituting' a main controlling-valve for the pressure, and by this Valve,with the initial opening' thereof, the iilling-tube and the closing-head descend, and at the same time pressure is equalized-between the filling-tank and the to-be-illed package, and that with the establishment of a full communication for carrying down the fillingtube and opening the closing-valve at the en`d thereof to admit liquid to the package communication is maintained between the package and the filling-tank by which the pressure forced out from the package by the inflow of the liquid'is carried back into the iilling-tank, and that with the reverse of the flow of pressure to the cylinder operating the rilling-tube the outiiow of pressure from the iilling-tank in the direction of the package is shut ott', thus maintaining' the full pressure in the tank. This arrangement of a single main controlling- Valve enables the operator to work the apparatus quickly and eifectually, as the only part requiring any special attention is the single main controlling-Valve.
