17 Claims.

My present invention relates to improvements 15 other advantages, the use of means to exhaust the fluid from the lowest point inside the container is fundamentally the factor that makes the automatic or semi-automatic reconditioning of container interiors possible, though many other factors cooperate therewith to render container reconditioning effective and economical.

One of the factors determinative of the actual utility of apparatus of this type is the rapidity of operation. My invention makes it possible to solve the problem of drying the interior with certainty so that automatic or semi-automatic container reconditioning is attainable. With that fundamental solved, it is then possible to construct machinery that will be both economical and efiicient. Prior to my invention, the uncertainty of eflicient drying made it impossible to determine the many other problems that relate toefliciency and economy.

Withcontainers having their bung holes in the ends, there is a real dlfllculty in that the bung holes are not only of different sizes but also vary in their positions in relation to the sides of the container. While containers of this type may be supported in canted position to collect the,

40 fluid, to reach the lowest point in every container to thoroughly dry its interior is a real problem.

In my present application, I have shown my solution of that problem by utilizing a fluid exhausting member that may be'ext'ended within 46 any container to reach automatically the lowest point. I have provided a container receiver in which containers are held in a canted position. Because of the variations in'the shortest distance between bung holes and side walls, my con- 50 cept also includes means to permit the degree of inclination of containers to be varied to varythe position of the side wall in relation to the fluid exhausting means.

I have shown my new fluid exhausting member 55 as applied to various types of equipment which are representative of the individual requirements as determined by the quantities of containers to be reconditioned and the amount of capital outlay warranted.

Any type, while a maximum capacity and the degree of automatic control desired, must include an adjustable fluid extracting member for real, efficieney. I have, however, developed 'many features which are of real utility in any reconditioning apparatus.

The types shown in my present application are representative. 1 have shown my newfluid exhausting member as applied to the apparatus shown in my copending application, Serial No. 689,425, in which containers were progressively reconditioned. I have also shown new equipment of smaller capacity, in which a plurality of containers are reconditioned simultaneously. In these types, the necessary re-use of and controls for the fluids present problems which are not present in a third type in which containers are manually moved from station to station in each of which specifi c' operations are performed.

Many other improvements in container reconditioning apparatus will be .noted as the description of apparatus shown is developed in detail.

speciflc features are of importance in all reconditionlng apparatus, and the novel fluid exhausting means for use in reconditioning containers having bung holes in their ends may be best understood from a detailed description of a characteristic type.

The apparatus shown in Figs. 2 and 3 will be where a necessary descrip- The fluid circulating system For my apparatus I provide a housing structure having a front wall I, a rear wall 2, and end walls indicated as at 3, a bottom 4, and a partition which with the dividing wall 9 forms the tank W for the washing fluid and the tank It for rinsing fluid (see Fig. 6).

In Figs. 5-9, the details of the tanks, the heating means, and the general system for the circulation of fluids may be best observed. I

. In Figs. 5 and 6, it may be seen that each of. the tanks W and R is provided with steam coils I connected to any suitable source -(not shown) by an inlet 8. A steam outlet 9 is provided which leads to a common discharge Ill. The steam inlets 3 are controlledby the manually operated valves I l and also by the valves l2controlled' by the thermostats I3.

The tanks W and R are fllled through the fluid inlets it (see Fig. 9) which are controlled by the valves it. Both of the tanks W and R are provided with a drain it controlled by the valves H (see Figs. 6 and'8) r In Figs. 5 and .6, the overflow system may be best seen. The fluid level in the tank Wis maintained by means of the overflow 2i which commumcates with the drainage pipe 22 (Fig. 5). Into this drain pipe 22 alsoleads the combination overflow and scmn trap I! for the rinsing tank It. The tank provided with a separate scum trap i9 which extends throughtthe casing wall 2. as shown in Figs. 6 and "I, whichis controlled by the valve 29. This scum trap is necessary because the scum in the-tank W is generally of an i oily nature and its disposal is frequently governed by statute or ordinance. Any scum in the rinsing tank-R however may be passed ofl through the drainage pipe 22. The overflowfl, in the washing fluid tank W extends well .belowthe desired fluid level so as to be free of the scum which is disposed of as stated above through the. trap I9.

A pump 23 has an intake 24 from the tank W and an outlet pipe 23 which, as is shown in Fig. 9, extends the length of my'apparatu's and is bent back upon itself and .provided with a pressure the member ll.

valve 29 disposed to discharge fluid back into the tank W.

A pump 21 has an intake 29 from the tank R and an outlet pipe 29 extending substantially the length ofthe apparatus parallel to the pipe 25 and is bent back and provided with apressure valve 39 to return fluid to the tank R.

A conduit 3| from a suitable source of air under pressure (not'shown) is disposed between the pipes 25 and 29. I

In Figs. 1, 7 and 8, I have shown the upper portion of my device. The front wall hand the partition 5 have flanges I" and 5*, respectively, on which the container receivers 32 are seated.

The receivers are formed with sloping side and bottom walls 93. At a suitable place on the bottom or floor of the receiver 32 I position my nozzle 1 and siphon over an aperture 34. When not given particular attention as in Figs. '1 and 2 my nozzle and siphon are generally indicated as at 35.

.The receivers 32 are provided with a cross member 39 which is recessed as at 31 to support one side of a container having a bung hole in its side so that the nozzle and siphon 35 will extend within a hung hole. Containers having their bung holes B in the'end are supported in a canted position in the receivers 32. This is effected by utilizing A a support 39 substantially below the level of the cross member 39 so that such a container may be supported to permit the nozzle and siphon 35 to enter the bunghole 1B of the container. Containers which are to be supported in canted position present another problem. The edges of Q the bung hole either extend outwardly or inwardly of the container head and the length of the chimes varies. As it is necessary to keep the lowest point of container within reach of the siphon I provide the 'block 33 for use with containers having a chime inadequate to be used to position the container properly. .The block 39 is adapted to support the container bevel adjacent the bung hole.

A second support 38' is adapted to support the 1 chime of certain types of containers. Both of g the supports 33 and 39" are supported by a shelf v 33 which is adapted to support the edges ofstill diflerent types of containers.

As shown in Fig. 9 the space between receivers 32 may be covered as by the plate S.

Below each receiver 32 I position a valve casing 39 which extends through the front wall i to which it is locked by a threaded cap. The casing 33 is supported rearwardly by .a flanged member ll which is inserted through the partition 9 and suitably secured to the casing 39 as at 42. The top of the member ll is slotted as at 43 for a purpose hereinafter to be described.

The valve casing 39 is provided with an'inlet aperture 44 into which is threaded a pipe 45 tapped into the washing fluid pipe 25. A second aperture 49 receives a pipe 4'! connected to the rinsing fluid pipe 29 and a third inlet 48 connects the air conduit 3| to the casing 39.

Outlets 49 and 39 are connected to a common outlet II which leads to the nozzle, see Fig. 1, and the casing 39 is provided with another outlet 52 from which an air line 53 extends into the receiver to the nozzle and fluid exhausting means 35 as may be best seen in Fig. 15. I

The details of the valve casing'andthe valve may be most clearly seen in Fig. 1. The valve consists of a plurality of pairsof discs mounted on a stem 54 which is secured to an extension 53 by a pin 39 extending through the slot 53 in This permits the valve to be easily removed for repair or replacement. The

extension 55 carries a cam contacting roll 51 which is supported by a slide 58 suitably supported between the rear wall 2 and the partition 5.

Another pair of members 68 is adapted to connect the air inletpipe 48 to the outlet 52 while a third pair of members 6| is adapted to be positioned to permit rinsing fluid to enter the casing 39 through the inlet 46 and to reach the outlet 5| through the delivery port 58.

The pairs of members 59, 58 and 6| are positioned so that when one inlet is connected to an outlet the other outlets are closed, and the stem 54-may be positioned to close all outlets. It will be also noted that it it is desired to change the valve from a position where one fluid may flow to a position where the other fluid may circulate, the valve will first open the air line. I therefore place a pair of drains 63 on eachside of the air inlet 48 so that when thepair of members 68 is positioned to open the air line, adjacent members of adjacent pairs will permit fluidto flow back through the drains 53 from the outlets 49- and 58, thereby draining the valve casing 39 before the next fluid is permitted to flow.

I thread into the outlet a valve 64 which may be operatedby through the wall I. A pipe section 66 having a flange 61 enters the aperture 34 in the receiver 33. The pipe 66 is threaded into the valve 64 and is threaded to receive a nut 68 by which a washer 69 may be compressed to seal the aperture 34.

Each of the receivers 32 is provided with a drain 18 disposed over a drainage conduit 1| whichextends the length of my apparatus. The conduit 1| is supported on beams 12 braced as at 13..

The valve drains 63 also discharge into the conduit 1 I.

The drainage conduit 1| is formed with a drain outlet 14 over the wall .8 dividing the tanks R and W. In Fig. 11 I have shown a valve 15 which is pivotally mounted as at 16 on the wall 6. The side walls of the valve 15 are sloped to bear against the bottom of the conduit 1| on either side of the drain 14 directing the fluid into either the tank W or the tank R. The pivot 16 extends through the partition 5 and is provided with a handle 11 (Fig. 11).

By the structure so'far described, either washing or rinsing fluid may be circulated depending on the position of the delivery valve and the drain valve 15 as with the structure shown in my copending application, Serial No. 689,425. The delivery valve is identical and the circuits and controls have, in general, been modified only as required by the different types-of apparatus illustrated.

The nozzle and siphon construction The nozzle and siphon generally indicated at 35 may be best viewed in Figs. 1 and 2, while the the handle 65 extending.

Suitably secured to the tube at and to the block 8| is a fluid exhaust tube 83. The tube 83 is closed at both ends, but is apertured as at 84 to receive the pipe 85 leading into the suction chamber 86. The tube 83 is bent similarly to the tube 88. but is shorter. The upper end of the tube 83 is shaped to present a. surface substantially vertical.

A block a1 is secured to the tube at. The block 9| is connected to the suction chamber 86 and the line 92 extends upwardly adjacent the tubes 88 and 83 to which it is secured. The air line 92 extends through the passage 98 to discharge air into substantially the highest point in the interior of containers and this -inrushing air through the pipe 9| creates a suction in the chamber 86 which exhausts fluid from the container into the chamber 86 through the parts 83, 93, 94, 95 and 95, as hereinafter more fully explained.

At the bend in the tubes 88,83, and 92, the tube 83 is apertured as at 93 and the hollow pivot 94 adapted to support the hollow arm 95 is threaded therein. The pivot 94 is provided with a passage 96 to align with passage 95' in the arm 95 which may be pivoted downwardly a desired extent toward the lowermost point of the container to exhaust any fluid which may have been collected there.

A sleeve or extensible tip 91 is mounted on the arm 95. The arm 95 is formed with a groove 98 in which the lug 99 on the tip 91 slides to adapt its-operating length to difierent sizes and styles of containers. The tip 91 is provided with a fluid intake I88. The block 81 has a flange 88 serving as a stop for the arm 95 andtip 91 when in inoperative position as shown in Fig. 13.-

The extensible tip 91 on the arm 95 is carried into the lowest point of the container before the fluids or air are discharged into the container through the valve 39 by means to be later described in detail. It will be understood that as air is discharged through the pipes 9| and 92 (Fig; 15) any fluid in the container will be sucked into the chamber 86 through the tip 91 and members 95, 94, 93, 83, 84, and 85, and from this chamber 85 it drains to the floor of the receiver 32.

The mechanism to move the arm 95 and ex tend the tip 91 to fluid exhausting position will be later described after the general operating mechanism in difierent types of apparatus has been considered.

Apparatus operating mechanism As the types of apparatus illustrated in Figs. 1 and 2 are operated differently, they will be separately described although the fundamental prin-, ciples are the same.

In the form shown in Fig. 1 a driving moto I8| is located between the walls 2 and 5 (see Figs. 8 and 9). The motor |8I rotates a shaft I82 as by the belt I83. The shaft I82 is provided with worm gears I84 (see Fig. l) in mesh with gears I85 on shafts I86 mounted on bearings I81 on the walls 2 and 5. Secured to each of the gears I85 are the operating cam wheels I88 (see Figs. 1, 7, 8 and 11).

On each of the shafts I86, is a cam wheel I88 having a. series of cams on its face of different shapes. These cams are adapted to contact the this operation to be continued for a desired length i of time and then to connect the air conduit for 9. length of time sumcient to permit the fluid to -1 and which will be later described.

be exhausted from a container and the valve casing 39.

The cam III is adapted to close the air conduit and to open the rinsing fluid conduit while the cam II2 .closes the rinsing fluid conduit and again opens the air conduit until the containers are thoroughly dried. At a predetermined point on the cam I09, all the conduits are closed.

As on a complete revolution 01' the cam wheel I03 a container is thoroughly reconditioned, I

. provide mechanism to shut ofi the driving motor I.0I when all conduits are closed This mechanism includes a switch generally indicated as at H3 secured to an end wall 3 as may be best observed in Figs. II and I2. switch -I I3 is in control of an electric circuit to the driving motor IOI which circuit includes a light H4 (shown only in Figs. 5 and 9). The switch H3 is adapted to close the circuit when the handle H5 pivoted as at H5 is held. A pivoted latch III controlled by thespring H8 holds the handle H5 when it is manually moved into circuit closing position. The lower end of the latch II! is provided with a stud H9.

Secured to the rear of the cam wheel I08 is a bracket I20 which receives the threaded bolt I2I. The end of the bolt I2I is adapted to contact the stud H9 to open the circuit when all conduits to the receivers 32 are closed. As the to the receivers bolt I2I is threaded'into' the bracket I20 very accurate adjustments may be made so that the latch I I! may be tripped at the correct moment.

As is shown in Figs. 9 and 11 one or the members I09 is provided with a cam I22. Guided in brackets I23 and I24 is a rod I25 having a por-' the valve I5 as the difierent fluids are injected,

i. e., this cam has a surface adapted to move the valve I5 to position to guide the drainage from the receiver and valve when washing fluid is being delivered and during the succeeding drying operation back to the washing fluid tank W; and has another cam face adapted to position the valve I5 so as to direct the drainage to the rinsing fluid tank B. when that fluid is being delivered to the containers and during the following drying period.

A third cam I30 is rotated by the shaft I05. This cam I30 is adapted to control the siphon po-. sitioning mechanism most clearly shown in Fig.

The type of apparatus illustrated in Fig. 2 is shown in detail in my co-pending application, Serial No. 689,425. This type diflfers from that The outlets I45 towards whichever of 2,115,204 I previously described primarily' in the operation oi the valves.

The container receivers 32 are mounted in a circular superstructure or support I 3| rotatably mounted on a circular base I32. The superstructure I3I has a central supporting hub I3I bearing on the base I32 which also supportsa gear I3I in mesh with a pinion I3I rotated by any suitable means (not shown). The superstructure I3I is also supported by wheels I34 adapted to travel along the track I33 as the superstructure rotates.

In the base I32 are located the fluid tanks.

From the washing fluid tank W; fluid is pumped through the conduit 25 which extends freely through the hub I3I and includes in the superi structure I3I a swivel joint 25. The conduit 25 includes a substantially circular portion under the receivers 32 and has, in its end, a pressure valve 25 disposed to discharge fluid into the tank I 42.

The rinsing fluid conduit 29 extends from the rinsing fluid tank W and passes axially through the hub I3I" and includes a swivel joint 29* and a substantially circular portion disposed under the receivers 32 and has a pressurevalve 29' disposed to discharge rinsing fluid into the. tank The air conduit 3I, from any suitable source (not shown) has a swivel joint 3| and a circular portion disposed under the receivers '32 between the conduits 25 and 29.

' The type of apparatus shown in Fig. 2 may be appreciated when it is understood that the receivers 32, the valves 39, the nozzle and siphon construction are identical with the construction shown in Fig. 1 and they are held in operative position by a construction modified as required by the circular support I3I. That is, while the valve casing 39 is held in the front wall I35 by the'cap 40 as in Fig. 1, the rear wall I35 is so positioned that the casing 39 is supported as at A circular wall I30 secured to the base I32 has a circular sheli' I40 upon which are mounted cams to be contacted by the rolls 5! to position the valves. These camsare adapted to control the valves in the same manner as the cams I09, H0, III, and II2.' On the shelf I40, I have shown the cam I which has positioned the valve to close all conduits to the receivers 32. I have also shown another cam I4I which has moved the valve to permit the injection of rinsing fluid into a container.

On the base I32 is a circular drain conduit I42 to receive the discharge from the pressure valve 25 in the washing fluid pipe 25. A similar conduit I43 is adapted to receive the discharge from a pressure valve in the rinsing fluid pipe 29. The dividing wall I44 is formed to permit the conduit I42 or the, conduit I43 to receive, drainage from the receiver drains I0 and the valve drains 53 as they rotate over zones of fluid circulation as defined by the cams on the circular shelf I40.

Each of the conduits I43 and I44 is'provided with a drain I45 disposed to permit the return of the fluids into the propertank located in the base I32. If more than one tank is used for each fluid, I provide a drain I45 under each of the drainage outlets I45 which drains I45 are open as at I41 to permit .ati to return to the tanks in the base I32. The drain I45 may be provided with a valve to direct the fluid from each of the the openings I4I isdesired.

As the controlof the circulation of the fluids and the air results from therotation of the support I5I I position on the base I52 a cam I45 which is used to actuate the siphon positionin mechanism to be next described.

The siphon positioning mechanism I pivotally secure to the siphon tip 51, a bar I50 to which is pivoted a link I5I mounted on a pivot I52 in the container receiver 52. I secure another link I55 to the pivot I52 which bar I55 is connected to the bar I50 by the connecting rod or bar I54.

The floor of the receiver. 52 is formed with a housing I55 through whicha rod I55 extends into the receiver 52. This rod I55 is pivotally connected to the link I53 by the link I51. In Fig. 1 the rod I55 is guided in the beam 12. 7

On the rear of. the wall 5, I bracket a shelf I58 upon which I mount a stud I55 surrounded by the spring' I55. The wall 5 is apertured as at I50 to permit one end of the lever I5I pivoted as at I52 to the receiver 32 to lie between the cam I50 and'the spring I55. The other end of the lever I5I is apertured to receive the rod I55 between which and a collar I55 on the shaft I55 is a spring I53. Below this end of the lever I5I is a pin I54 through the shaft I55.

In the position shown in Fig. 1, the siphon extension 51 and operating mechanism is shown in full lines in inoperative position and in dotted lines in operating position. In this position the cam portion I50 is in contact with the lever arm I5I and the spring I55 is correspondingly compressed. As the cam continues to rotate, this engagement of cam portion I50 and lever" arm I 5| terminates and the tension on the spring I55 is released, and thereupon its normal action forces the lever arm I5I up into engagement with the surface I50 of the cam. Such operation rocks the lever I55 on its fulcrum I52, and as the drop from the portion I50 to the portion I50 is abrupt, the correspondingly abrupt movement of the lever I55 causes a quick downward movement of the shaft I55.

The link work described above will be thereby actuated to swing the bar I50 outwardly and the bar I5I downwardly to carry the siphon tip 51 against the side wall and into the lowest point in a container in a canted position in the receiver 52. With'the continued rotation of the cam I55 the portion I30 again actuates the lever I8I' against the spring I55 and the lever I5I carries the rod I55 upwardly returning the link work to its full line position of Fig. 1 in which the siphon tip 51 is returned to inoperative position. The spring I55 cushions the return action and tends to hold the parts in their full line inoperative position of Fig. 1. v It should also be noted that.if the link work is strained while the cam I50 limits movement of the lever I5I, the spring I55 serves to protect the link work by permitting only limited move- 3 the stud I55 on vided with a collar I10 between which and the of the rod I55 and is slotted as at I51 to receive the rod I55. The rod I55 is promember I51 is a spring "I.

As the support I5I rotates, the roll I58 will be carried off the cam I48 permitting the spring I55 to actuate the rod I55 to lower the siphon tip 51' 'as'has been described. The spring I55 has therefore a function similar to the spring I55.

When the complete rotation. of the support I5I carries the roll ,I55 onto the cam I48 again, the spring "I actuates the rod I55 similarly to the spring I55.

when the roll I55 is on the cam I48, limited movement of the tip '51 or the linkwork is permittelrz by the spring "I and the length of the slot 5.

positioned in desired fluid exhausting position regardless of the variation in the distance from the bung hole to the wall. This mechanism is adequately protected so that it will not be un-' duly strained when the tip 51 has reached the lowest point possible whether in a container having a bung hole on its side or in the end. It is to be noted, that different containers may be supported in slightly different positions due to the supports 55 and 35 and 38.

In each of the types of apparatus, the cams I50 (Fig. 1) and I45 (Fig.2) restore the siphon to the positions shown in Figs. 1 and 2 to permit the removal of reconditioned containers at which problem and I have shown only so much of the Y apparatus as relates to that operation.

The container receiver 52 is secured to the rear wall I50 as at I5I and to the front wall I82 as at I55. I I 4 The container receiver 52 consists of a pair of side members I54 and cross members I85, I and I51. The members I54 are spaced apart to permit a container 0 to be positioned on its side in a zone limited by the cross members I55 and I51. The members I54 are formed with recesses I58 which define a zone to-receive'the edges of a container C Both of the containers 0 and C are therefore held in a canted position. On the ends of each of the side members I54 a pair of supports I 55,and I50 are secured. These supports are bent inwardly to hold a pair of members indicated as at I5I which are closed at each end as at I52to define a slot.

' An air conduit I55 enters through the rear wall I85 and includes a portion I54 supported on a shelf I55 braced as at I55. From a suction pump indicated as at I51, a suction pipe I55 extends through the rear wall I50 and is supp ted on the shelf I55. 0n the shelf I55, the air conduit I55 and the suction pipe I 55 are provided with ture 255. The conduit I55 and the suction pipe lll includea swivel Joint 20 I:.beyond--which there are elbow joints 202. From the joints 202, the

w providedwith a plurality of Jets indicated as at ill. 1

The auction pipe I989: shaped to enter the elbow 203 and pass through the member 204 to provide a tip 208 curved similarly to the member 204. The end of the member 204 is suitably sealed to the tip 206.

In apparatus of this type, containers are placed in the receivers 32 and it will be noted that they may be positioned so that their bung holes, whether on the end or on the side, may be entered by the member 204 and the tip 206. When the containers are so positioned, the fluid exhausting means -just described may be pivoted to enter the bung hole and reach the lowest point therein.

The joints I99 permit the pivot point of the fluid exhausing member, the joints 2', to be varied so that the fluid exhausting member may be positioned to enter any bung hole when its container has been properlypositioned in the receiver 32. The tip 208 is resilient, permitting the thorough reconditioning of all containers.

The air line I93 may be controlled by the valve 201 or the valve 208 and suitable switches may be positioned near either of said valves to control the suction pump Ill.

While this apparatus is extremely simple, it is efiective for use where the number 01' containersto be reconditioned is not Conclusion My invention, as illustrated in the typical embodiments, permits the thorough drying of containers having bung holes. As this may be done with certainty, it is possible to determineirom the desired capacity what automatic and semiautomatic controls are necessary to give 1 the greatest economy and eiiiciency.

What I therefore claim and desire to secure by large.
