- the nozzles 30, 31, are usually arranged somewhat remote from the path traveled by the containers so that the spray will'be fully atomized by the time it reaches the. containers and will deposit the atoms of liquid throughout the full length of the containers and produce the'fog or cloud of vapor that will in effect completely envelop the contain-' ers and soak or penetrate the surfaces thereof without resulting in uneven deposit thereon and particularly avoiding the deposit of lumpsof paraffining or waterproofing mate-- rial.
- the upper nozzle 28, is usually arranged somewhat closer to the containers than the nozzles 30 and 31, so as to deposit an ample supply of waterproofing liquid on the upper ends of the containers to fill the. seams or joints between the container bottoms and side walls thereof and if so desired, to spray downwardly along the exterior sides of the containers.

A "suitable conyeyer is arranged in said chamber,- and' thisconveyer is -.preferably constantly traveling along an extended path of movementwithin the chamber and is provided with a multiplicity of brackets, 9 holders, or supports, each adapted to carry v a single container in an inverted position so that the conveyor will be capable of 'stmul teneously carrying a large number of con"- tainerswithin said chamber and of eon- 1w discharged in said chamber drains'or drops X stantly advancing the same along said path from a point where the containers are suc-.
cessively placed on the supports to'a point where the containers are successively discharged or removed from said supports after havingtraveled the length of said path within said chamber. Near the beginning of said path "of movement means are provided to spray waterproofing liquid over the interior and exterior surfaces of the containers as said containers successively pass said meansduringthe travel of the conveyer; This liquid is drawn from the tank-and liquid back into the tank fexceptwheretaken up by the surfaces of the containers.- The con 'tainers after being subjected both .exteriorly and internally to the waterproofing liquid move along the extended pathwithin the chamber and surplus liquid isdrainedtherefrom and the liquidon or in the surfaces of the ontaine'rs" sets'or driesabefore sa-id'con suitable supporting means. -However, any. suitable means can be provided to maintain the waterproofing liquid inthetank 1 at the desired-temperature, andmy invention is not limited to the'provision of a steam coil 2,

. .If'so desired, the upper portionof each bracket can be provided with laterallyprojecting bentwire arms 23, braced bywires 24, to engage thevertical inner surface of the container and hold the container'm the desired position and 'againstswinging or oscillating on the bracket-c ltwill be noted that thebrackets. are arrangedat an :upward outward inclination, so-. that the containers in assuming a vertical position, w ll-have their lower open ends approximatelyunob entrance of; liquid structed for the free spray from below. a R
The table rim 19, is spaced adistanc'e from the vertical surroundi ng'wall of the casing 3, and the brackets "20," are arranged to carry the containers invertical positions a and in a circular path near but spaced from the vertical wall of the casing with/their open ends over the space between said run andsaid wall andpreferablydirectly above the inclined drainage floor 5, ofthe casing so that liquid draining from the containers will drop onto said -fioor. The table is pref-. erably approximately closed betwee'n the hub 17, and rim 19-, by a floor or plate 25,
to form the floor or bottom of the waterproofing and drying chambers hereinafter referred to. y p p The casing,3, is provided with an opening, such as b, in its vertical wall, through which the operator canextend the hand'into the casing to supply containersto the rotary table by placing them on the brackets 20, as they successively move a st' said opening.
This opening I), virtua ly establishes the receiving stationfor the rotary table, or the from end tr the extended path along which the containers 7 travel in" the "casing. s The discharge station forthe rotaryconveyer 'veyer or encircle theinterior of the casing.
A container spraying chamber isp'rovided theopening b, in 'the'direction of movement 'of the rotary conveyer, and thischamher is traversed bythe" path along which the containers traveL; This chamber'in thisexample, is'fsh own} formed by the vertical parti- 'tions 01' plates radiating approximately *from the center of the casing tosthe vertical wall thereof and extending, from the top wallv of the casing" approximately ,downto a the rotary conveyer and secured to and supported from the top wall. ,The'lower-outer corners of these partitions are notched or cut away'for thepassage of the upright brackets of the conveyer and the containers carried thereby into and from said chamber. Within thisichamber I locate spraying and atomiz ing devices designed and arranged to coat or subject the complete exterior and interior surfaces of each container withor' to'the action of the liquid discharged by said dea vices so that when each container leaves said chamber it will be completely coatedorimpregnated both externally and internally with the waterproofing substance. To this end, I arrange a" downwardly discharging liquidspraying or atomizing nozzle 28, in said chamber and above the path traveled by the containers to thoroughly subject the upper ends ofthe containerswith the liquid spray; and an upwardly discharging liquid spraying or atomizing nozzle 29, below the path of the containers throughthe chamber to direct spray up into the containers and thorou hly coat or impregnate the inner surfaces t ereof withthe liquid; and horizon tally discharging" and oppositely-arranged liquid spraymg and atomizing nozzles 30,
31,located at opposite sidesjof the path of the containers and directing spray radially with respect to the conveyer to thoroughly coat and impregnate the exterior vertical surfaces'of the containers with the liquid. These several spraying heads or nozzles are 32, and are supplied with liquid under pres sure bybranch pipes from the liquid supply pipe 33, forming the discharge pipe of any suitable pump 34, arranged to draw liquid provided with regulatlng and cutoff "valves from tank 1, and drivethe same under the desired pressure through said pipesgto the several'nozzles. In the example illustrated, the pump -34:
is shown submerged in the liquid in the tank and is actuatedby sprocket chain 35, from shaft '36, extending to the exterior of the tank and driven by belt applied to pulley 37.
The nozzles 31 are usually spaced a distance from the containers toward the center of the casing, while the nozzles 30, are spaced a distance outwardly from the containers beyond the circle in which they travel. The casingis formed with a narrow offset recess or pocket 38, to receive the nozzles 30, and this pocket is usually provided with a removable cover 39, through which access can be gained to said nozzles 28 and 29, and the interior of the spraying chamber. Access to the nozzles 31, can be gained through an opening suchas 26, in one of the partitions 26, from the interior of. the casing on the removal of one of the top sections 6. The pocket 38, is normally closed, except at its inner end, where the pocket opens directly into the spraying chamber,
and the floor of the pocket is preferably arranged to drain onto the casing floor 5, that drains into the tank. The various nozzles are so arranged as to completely and successively envelop the containers in a cloud or fog of spray or atomized liquid, and a cloud or fog of atomized water proofing liquid is approximately present in and around the containers so long as they remain in the spraying chamber even while not in direct alinement with the nozzles and hence the containers are subjected to the soaking efi'ect of this fog or cloud for a more or less extended period while in said chamber; that is, for a greater length of time than it takes each container to pass the position wherein a it is in direct alinement with the nozzles.
The nozzles 30, 31, are usually arranged somewhat remote from the path traveled by the containers so that the spray will'be fully atomized by the time it reaches the. containers and will deposit the atoms of liquid throughout the full length of the containers and produce the'fog or cloud of vapor that will in effect completely envelop the contain-' ers and soak or penetrate the surfaces thereof without resulting in uneven deposit thereon and particularly avoiding the deposit of lumpsof paraffining or waterproofing mate-- rial.
The upper nozzle 28, is usually arranged somewhat closer to the containers than the nozzles 30 and 31, so as to deposit an ample supply of waterproofing liquid on the upper ends of the containers to fill the. seams or joints between the container bottoms and side walls thereof and if so desired, to spray downwardly along the exterior sides of the containers. The lower nozzle 29, is also usually arranged somewhat close to the lower vends of the containers so that the, spray therefrom will thoroughly saturate the complete inner surfaces of the containers ample illustrated, I show an air blastnozzle- 40, depending in the spraying chamber above the path traveled by the articles a, and arranged in advance (in the. direction of rotation of the conveyor) of the point where the containers pass between and in alinement with the spraying nozzles. This nozzle is arranged to direct a downward blast of air into said end pocket of each article a, to expel the surplus liquid therefrom into the spraying chamber. also serves to hasten the setting and drying of the liquid soaked and impregnated. surfaces of said pocket. This air blast nozzle is supplied through air pipe 41, depending through the top wall of the casing, and operatively connected through a suitable valve mechanism with main air supply pipe 42,
having cut off valve 43, and extending from any suitable air compressor. The valvemechanism referred to is erably arranged to normally maintain the pipe 41, cut off from the supply pipe 42, and to only periodically connect the pipe 41, with supply pipe 42, and hence only periodically permit the discharge of the ai-r blast through nozzle 40; The valve mechanism is so timed that the air blast will be but ap- This .air blast prefproximately momentarily established and y then only when a container (or other article being treated) is located immediately below the blast nozzle 40. The arrangement is such that each container passing under the nozzle 40, will be subjected to the momentary air blast, the air blastbeing cut off while each article is moving to and from position in immediate alinement with the nozzle. Various valves or other mechanisms can be provided to thus control theair blast, although in the example illustrated, I show the same timed and controlled by a rotary flat faced disk-like valve 44, rotating between and in closing contact'with the alined otherwise open communicating ends of the pipes 42,41. This'disk is provided with ,a
transverse port 45,- adapted to register with said open ends of the pipes and place them in open communication once during each rotation of, the disk, but to cut the pipe 41, off from communication ,with the supply pipe 42, during .the'remainder of each rotation. The rotary diske ltis carried and poweror drive shaft 13, andfthe gearing 47,
- so times the rotation; ofthe'f'disk 44:, as to establishthe airiblast only when firrthe rota tionl ofthe conveyenfeach article is directly -belowthejblastf nozzle. a
- .air tight contact between the end? edges'of the open' ends of. the- pipes 42, 41,'and the 7 InYorder. "to maintain the approximately side faces, of the disk, I preferably-grind said edges and .the faces of the disk,*and
yieldingly. press the pipe ends to the faces'of the disk. For instance, the pi'pes ll, 42, can be arranged with two approximately-'parah oppositealined open pipe ends 4 8,arranged at 'oppositesides of the disk 'and"paral1el with its axis of rotation with theedges surf rounding their openings held against the.
sides of the disk by a retraetive spring-49, extendingbetw'een and 1 joined to said flexible pipe lengths and tending pull them" together.
The containers or. other articles being treated pass from'the sprayingpr water- I proofing chamber, to the interior of the easf ing, that-is shut off from the spraying chain her by the partitions 26,- and the conveyer floor 25, andthat' constitutes" the drying or setting chamber. i The liquid flowsdown-and 'evenly-dlstributes itselfover the container surfaces, and snrplnsliquid drains and drops there-.
from onto the casing'bottom 5, while the containers are in the spraying chambenand in fact possibly this may betaking place after the containers have passed from the spraying chamber intothe" drying chamber.
However, the containers have an extended path of movement through the drying chamber before they :reach thedischarge c, and while in said" chamber the surfaces of the containers, become suf ficiently dried and. set to be delii ered therefrom. -While in said chamber, the containers are subjected tothe heat'rising'from the? hot liquid in the tank 1, and" are protected 'from thefl-vapor'fog generated by the spraying nozzles. i As the containers successively arrive be side the discharge opening c, they'can be removed by hand from the brackets supporting them and from the casing, but. I-fprefer to automatically'discharge the waterproofed containers as the conveyer presents them one at a time besidesaid discharge opening, and
hence avoid contact with human hands, as
well as thepresenceo-f an operator. Various means can be provided for thusdis charglng the containers, althoughin the ex 7 ampleillustrated, I Intilize an air blast from an upwardly directed nozzle 50, arranged within the casingand opposite the. opening 0, and directly 'under the: path traveled *by the containers. eachlcontainer arrives overtlns nozzle, ana1rblast'1ssues therefrom" and enters the open lower end of the opening a, and preferably causes the same to drop open endup at, thef exterior of the casing and onto an-upwardly moving con veyer 52, forming the -travelingfloor of a" trough 53, in which the containers can be" "carried to anysuitable location [forstorage' lel spaced straight laterally fiexible lengths I I at right anglesgto the axis of rotation 'of the disk, and these lengths can terminate in two orfurtheroperations; i
The deflector 51,]is; preferably so arranged with respect to the path of the containers th gsing throughthe upper d of open} ing c, and adjustably and removably sup- Ported by a bracket 54, secured t thebx l 'of the casing.
The air blastnozzle 50, is preferably supplied .withair under pressure from pipe 41,
through the pipe 55,[which forms a branch of; pipe 41, and hence the-blast is periodi established'through disk 44,as hereinbefore described, sothatthe container dis charging blastf will be momentarily established only when a semi ar -moves into alinernent therewith, and" simultaneously with the establishment" of r the surplusliquid-expelling blast through nozzle 40, although my invention isnot so limited.
If so desired, theitraveling conveyer floor 52, can-be driven from shaft 13, throughthe medium of suitable pulleys and aconnecti ng belt and a shaft carryingthe lower drum-of the saidconveyen, v so (1 sired, aguard flange 56, can be pro vided within the casing immediately above the opening I), to protect the hand of the operator when placing containers on the brackets of "the rotary I conveyer, from hot waterproofing liquid; that might drop" from the topwall of the casing. I The continuous rotary t avel of the articles to be treated, can be around-ahorizontal axis, f so desired, instead of around a verticalla-Xis, and m'anyothervariations, modifications and rearrangements canbe resort ed tojw thout departing from the spirit and Fig. 5,1 diagrammatically and partially illustrate, an apparatus, wherein the rotary conveyer 18?, forthe articles a,to be treated 'by liquidifrom thetankgl is rnountedon 1 scope of my invention'as defined by the herelnafter recited cla1ms. For instance, in

An upright or vertically arranged box or casingB, is

ranged as hereinbefore described, and supplied with liquid from the tank 1, as hereinbefore described. The continuously rotat- I ing conveyer 18, is provided-with inclined upright arms forv maintaining the containers, or other articles to be liquid treated, in upright inverted position as hereinbefore described.
