To allfaghm t may concern.'

Be itknown. that iva-CHARLES E.- BONINE,

of Melrose Park, in the township of Cheltenham, county fof vliontgomer and State of f Pennsylvania, and HENRY S/rAUFFER, of

Manheim, in` the` county of Lancaster and State of Fennsylvania, have-jointly invented certain new and useful Improvements in Milk-Can-Washing Machines, whereof the followin is a specification, reference being had to t e accompanying drawings.

The invention relates more particularly to a washing machine which is adapted for washing, thoroughly sterilizing an drying milk cans or the like.' Y An object of the invention is .to provide a machine of the above character, having a washing station, a rinsing station, a sterilizing station, and a series of drying stations to which the can is presented in succeion "so thatit ma i be' thoroughly cleansedan dried in an e cient manner and in a comparatively short time.

-A further object of the invention is provide 'a .machine'of the above character wherein the inside of the can is thoroughly washed andscoured with brushes which are caused to rotate and which are. Acarried against the inner surface of the can b-y ,3Q centrifugal force, the brushesbeing returned to their normal position by springs.'

A still further object of the invention Ais to provide a machine of the above character,

wherein the brushes for scouring the inner '-35 surface of the cans are carried by a single rotating pipe, which also serves as a means for supplying the washingwater to the inside of the can.

A, still further object of the invention is to 40 provide a washing device of the above character, wherein the washing water issupplied by means of a steam injector or Siphon,

vthe control of the` washing water being' through the means of aquick-( )peratin valve which is opened by hand, and whic is closed automatically on the starting of' a conveyer' for shifting the cans from one station to another. A still further object of the invention is to provide a machine of the above character, l

air for drying.

the cans are submitted to the action of steam for thoroughly sterilizing the same, and a` series of successive drying. stations, where the rinsed sterilized cans are subjected to warm At the-Washing-station, there is a series of rotating brushes, carried by a single ro# tating pipe, vertically disposed and supplying the washing Water for thecans. 'The can is. inverted and placed over these brushes. The can is held from rotation and is .raised and llowered by manually con.

trolled arms carrying brushes which engage theout'er side walls of the can. rlhe brushesengaging the interior of the can are mounted so as to be moved out into contact with the can through the centrifugal force acting on the same, and they are returned. to normal position by springs.

After the can has been thoroughly Washed, it is then presented by hand to the rinsing station. The can remains inverted on the su porting table while it is being'rinsed and is carried along the supporting table by traveling devices so thatthe can may' be presented successively to the rinsing station, .thence tothe sterilizing station, and thence to the dryingstations above referred to.

An endless conveyer or carrier for shifting the can from one station to another is :manually started and is automatically stopped so that as soon as the can is prop` erlypositioned relative to the operating station, the carrier stops. The washing water and also the rinsing water is drawn l' from the supply tanks .by steam injectors which force the water through the pipes to the 'proper places, for washing' and for rinslng, and thus vserve as the sole means for supplying the washing water to the cans. The steam which conveys the water is 4controlled by aquick-action valve which iS.

manually opened and` which is automativcally closed when the carrier is started to shift the can from one station to another.

Referring more in detail'to the drawings, my improved washing machine consistsof a main supporting frame 1,- which may 'be of any desired shape and construction for supporting the various members of the machine. The .Washing station is indicated at W, in Fig. Il, of the drawings, and as shown therein, said station is. atlthe left hand end of the frame 1. i Mounted in suitable bearings is a vertical rotating shaft 2.

This, vertical shaft 2, Ais in the form of a pipe, and said shaft extends well up above its Supporting .bearing which is indicated at Mounted' on the shaft,2, 'is a xed collar '41. Y collar 4, are three brushes 5, 5,* which are particularly adapted yforvengaging the mouth of the milkcan. shown as inverted and as engaging these brushes inFig. X, ofthe' drawings, where said canis indicated .at,C. The brushes 5, I5, are connected at their lower ends-to links,

6,6, which, in tujrn are pivoted to a collar 7, free to move on they shaft 2. A 'spring Pivotally secured to this fiXed.

Thelmilk can is 8, coiled about the shaftengages the collar y 7, at its lower end and engages a fixed collar` 9, at its upper end. This springonly forces the collar 7, downwardly into engagement with a fixed `collar 10, and holds the. brushes .drawn inwardly jto their eX- treme inward position. Y v. l y

As the shaft 2,rotates, the centrifugal force acting on the brushes 5, 5, `will force vthe lower ends of same'outwardly, comv pressing thespring 8, andv this causesl the brushes to engage the inner wall of the mouth of the can. Located above the brushes 5, 5, are three brushes 11. These brushes are equally spaced angularly about leo the shaft land are similarly supported.

Each brush is pivoted adjacent its lower end to a link 12, which in turn is pivnte'dI to a fixed collar 13, carried by the shaft 2.

To each link 12, is pivoted a doublelifnk 14. These links 14, are pivoted to a slid-v ing collar 15. A spring 16, is located between the collars 13, and 1 5, andA normally forces the collar 15, upwardly drawing the lower ends of the brushesv inwardly away from the walls ofthe can.

We have provided a link 17, for eachbrush 11. This link 17, has a' pin 18, slid ing freely in a slot 19, 'ina bracket attached to the brush. The lower end. of the link 17, is pivoted to a collar 20, which is fixed to the shaft 2. A spring 21, is pivoted at Y itslower end to the link 17, and at its upper end to' a fixed collar 22, carried by the shaft 2. There is a spring 21, for each link 17. Thesev springs normally tend to draw n the upper ends of the brushes 11, inwardly. From the above it will -be apparent that frame of the machine,

"wise on the shaft.

each brush is mounted so as to move independently at its upper` and lower ends, and

the centrifugal force' acting onthe'brush against the inner.

'on the collar 15,4 will drawthe lower ends of the brushes inwardly, The springs 21, will also draw the upper ends of the brushes inwardly.

Mounted on one of the brackets adjacent. to the upper end of the brushes is another brush, indicated? at 23, which is adapted to engage thebottom of the can, This brush is pivoted at 24, to 'theA bracket, and is provided Awith astop 25, which is adapted to engage the bracket and normally hold the brush. 23, substantiallyhorizontally. From the above it will be apparent that the can maybe lthoroughly scouredor cleaned on the inner 'face thereofby the brushes re1- ferred to, andthe washing water which is charged wlth a soda'solution is conveyed to the brushes and the inner walls of the can through the'shaft 2, which, as above noted, is in the form vof a pipe,and which has a The can issupp'orted' nd held from rotation, and raisedand.lowered-bytwoclamping arms 27 andf28. The semi-. cylindrical sections 29, 29, are bolted to arms 27,' and- 28, and these vsections which extend throu h- I out the greater length of the canfare pfovided with verticallyarranlged brushes- 30, 27,is formed inte- 30, and 3l, 3l. The arm grally withhe` sleeve 32. This sleeve v1s splined on a` shaft '33, so as' to `turn with the shaft, butsaid sleeve is free to moveend-v The shaft 33,. (seelig. VII) vis mounted to turn in bearings 34,'a-nd the bearing 35,'being carried' by-the frame of the machine and thebearing 34,.

being carried'by 'the bracket 36, bolted .to the wardly therefrom. The arm 28, is formed integrally with` thesleeve 37, which is'free uponV a shaft 88,

spectively. The sleeves 32, and y37,'arefa1so provided with rejecting 'armsf43, and 4 4, respectively. I hespringy45, is con'nec'zted-'t ol the outer ends gof. the amis 43,J:and44, and

this springunormal-ly tends to hold the arms.

This rocker 48,h'asits-freearmiterminating at its lower end, -andthisafrm is pivotally, 47 see Fig. 'HIT The and *extending 11pand this shaft 88, is mountvfreely mounted onrithel'sfhaft' 4 9.'

treadle 50, and presses downwardly, the rocker 48,throug'h the link 47, will cause the shaft 33,- to move in acounter-clockwise di rection, and t gears 4l, and 42, will operate the shaft 38; and thus cause awayA from the can, and release the same. Fromthe vabove,'it will be apparent that the arms 27, and 28, may be so, controlled by tlie'treadle..50,' and the spring45, as'to grip the can and-prevent. it from rotating-orl lightly engagef'the can permitting the same to rotate withthe inner brushes.. This enables. the can. to be rotated through contact with the, inner" brushes, 'and-- the 'outer his, through the segmental the arms 27, and 28, to swing A perforated pipel, is carried by the semi-cylindrical section 29, and this perforated pipe-.is suitably-"connected with the washing water as'wil'l be described hereinafter. Through this pipe the washingwater andithese brushes'arecarried by depending arms 54,* anfd 5 5', respectively, 'which are b'ilit'ed to thearms-27,and 28, respectively, see FigIX. Q

Thel slfeves 32, and37, maybe moved up and down on their,` :supporting l shafts by means of a bracket A'56. This bracket 56, (see Fig. vVTT) serves as a supporting'means for the lsleeves"-v32,-land 37. "A eha'in''?, is eonnectedto a' lug, attached to the bracket a sprocketrwheel 56 This chai runs over GQ, attached tothe4 other end of thec'hain serves las 'a means; for 'counter-balancing the weight of the can, and the supportingparts therefor'. The sprocketwheel 59, is'xnov'ed through a .part of a rotation byjmeansof a link" 61,' which is pivoted at- 62, to the 4sprocket wheel and which isxalsopivoted at 63fj,.to' an arm 64,

fixed 'to the-shaft49. The" ico 59 and nreshes"therewith.;i A-counter-weight lever 65, isalso fixed to the-'shaft 49, and

serves as a means for oscillating the arm 6 4.' The .link 61,-is formed in sections. The upper section `of the link carries' a guide V66, into which extends, The lower section-Tof' lthelink is .formed so as to slide in this guide. .Atspring .68', is interposed between/a headY on said lower section of the. ofthe guideA 66. This-spring'permits a -cer tain amount of lost-motion and together witlrthe guide permits the loperator `to shift the lever 65j lto accomplish fcertain results hereinaft'erf-f specitied,fwithout vmoving the can.. n:v i

` lt will 'be apparent lfromthe above de- .scriptionfthat when the lever 65, is swung to the right, as viewed in Fig; III, the lower iis the lower section :of the link 12o link and the lower end.

section'of the link 6l, willngradually slide, up in the guide and finally striking the ,up'per end of the guide 66, will rotate lthe sprocket wheel and raisethe can.V A move-4 5 ment o f the .lever 65, in the opposite direc-ution will lower the can onto the inner the main shaft which brushes'. `The shaft'l 2, carries a bevel gearv 69, at its lower end, which meshes with the bevel gear 70, on the shaft 80.- Thisshaft 80, carries a clutch having an inner member 81, which is free pn the shaft and .which carries a sprocket Wheel 82,- co-operating with the sprocketchain 83, which, in tur'n co-operates with the sprocket wheel 84, on

wheel 85, seeFig. II.

The outer member of the clutch indicated at 86, is splined to` the shaft 80, and has a free endwise movement thereon.

lever 87, is connected to this member 86, of

the clutch for shifting thesame. is pivoted to this yoke lever at one end and the' other'en'd of said linkis pivoted to a rocker 89. A spring 90, fastened at one 25. end to thelframeand at its other end to the yoke lever 87, normally tend'sto move the clutch members into engagement and to cause the shaft 2, to be driven from the mainy shaft. -Fixed to the shaft 49, is a controlcam-plate 91, whose acting `face cooperates vwith-the roller 92, on .the rocker 89. The cam face is shaped `so that when the parts are inthe position shown in Figs. III, and IV, the spring 90, shifts the clutch members, so as to bring them into engagement. When, however, the plate 91,`

' is swung in a clock-wise'direction, fromthe position shown in Fig. IV, the outer portion ofthe cam surface willV engagethe roller 92, and. separate and hold them separated so long as the roller is on thishigh'level of the controlling Y pleted, the shaft 80, will cease surface. A

The controlling cam 91, is so proportioned that the clutch will be shifted to rotatethe vbrushes immediately after. the` handle 65, is moved to lower the can.. This arran ment allows eve .portion of the interior of the can to be t oroughly, subjected to the acon ofthe brushes,eand also affordsl a ,'wide range' of movement between the can and brushes without" disengagement of the clutch. y

As soon aslthe can is-fully raised to its upper position after the vbrushing is com"-v permit the brushes to be disen aged; from the inner surface ofthe can. fter it has been raisedl to the proper vposition for removal, then. the operator by depressing the treadle 50, separates the arms 27, and 28, and releases the their can. Extending about the lower part of the can is a casing 93.` ,This casing is collected behind the baffle.

is driven by the belt` A yoke A link .88,"

the clutch members rotation and same from the grip upon Matese water is for the purpose of wetting a hand brush which is kept in the pool of water so as to be readily accessible to the operator and used to washportions of cans of such configuration as not to brushes provided regularly :upon the machine. J

The main -supporting .frame 1, carries'A a This wash be reached by the A supporting table or way on which the cans rest in "inverted position while they are bein rinsedsteri lized and dried. Extendingom` :end to end of the table are a series of supporting members iny the form of rods 9T he cans areremoved one at a time froml the washing apparatus and are placed on these rods 97, inverted as above noted.-

Passing along the upper surface of the l table' is an'endless conveyor which consists of two travelling chains 98, and99, `which areconnected at intervals by approximately horizontal cross pieces chains run over suitable sprocket wheels on the shaft 101, at one end of the machine; and suitable sprockety wheels 102, at the other end of the machine. rlhe rods 97, are bent downward at their shown in Fig. VI, of the drawings.y pieces 100, are of an clearl shown in Fig. a V-sii receive the neekof the 'inverted can and Cross I, and formed with 100. These endless ar cross sectionI as aped recess 103, which'is adapted tofree ends as clearly" .i

slide the same along the su porting rods 97.

Theucross pieces 100, area so provided with -a second V-shaped recess 104,. which isl adapted to engage the cover and slide along the rods 97, at the other side of the supportingtable. It will thus be seen that the cover for the can and thev can itself are simultaneously moved" along the supporting rods from one end to the other of the table.

4The rinsing station ie'indicated at R` in Figs. lll, V, and Vl, of the drawings. The interior of the can 'only is rinsed and this is accomplished by'means of a shower lof rinse water from a nozzle`105. This rinsing nozzle is located at the end of the pipe 106, which supplies the rinsing water. At tho rinsing station 'the cover is washed by means of a nozzle,"1 07, connected to the pipe 106.

A circular spray 108, is also connected with p said pipe 106, andan overheadwshower 109,

which is connected through the pipe 110, to the pipe 111, and the pipe A106, is also connected to this pipe 111.

In Fig. H, of the drawings, we have indicated atS, the sterlizing station. The interior of the can is subjected to live steam through a nozzle 112.v This nozzle is connected to a pipe 113. The cover is also sub'- jected to steam through a similar nozzle v114, a circular nozzle 115, and an overhead shower 116. These nozzles and the rsteam shower are all connected with the pipe 113. The steam is led to the machine from any suitable source of supplyA through the pipe 117, (see Fig. VI). The pipe 117, has a quick-action valvei`118, therein. This pipe 117, connects with the pipe 119, and the pipe 119, is connected with the pipe '113, so that whenthis quick-action valve 118, is opened steam passes through the pipe 119, and the pipe 113, and thoroughly sterilizes the rinsed can and the ,rinsed and washed cover.

The rinse water is led from `a suitable source of supply to al tank 120. The pipe- 121, is connected with this tank. The pipe `122 (controlled by a hand valve 123) is con'- nected4 to a steam injector located at 124, and connected with the pipe 12,1 through a pipe connection 125V The pipe 111, connects with this'stearnl injectoror siphon. The steam passing vfrom the 4pipe 119, through the steam injector will draw the rinse water.'

from the tank and convey the same through the ppe 111, to the pipes 110, and 106, and thus orce the rinse water out through the nozzles and the shower onto the parts to be rinsed.

It will be understood that as long as the steam continues Ito flow, the rinse water will be thrown against the can and the cover. The wash water is fed to the storage tank 126, from-a suitable source of supply and the valve controlling the inlet of the water is controlled by a float 127. A similar oatcontrolled valve is used in the rinsing tank.

Mounted on top of the washing tank is a small tank 128, for the soda solution to be' used in connectionwith the washing. rlhei'e is a port 129, leading from the tank 128, to

the tank 126, and a valve 130, operates to close'this-port. IThis valve is formed at the lower end of a rod 131, which extends up through the tank 128, and a spring 132, bearing on the collar 133, attached to the rod 131, normally forces the valve downwardly so as to close the port 129. This rod 131, is pivoted at 1734, to a lever 135, which runs on a controlling cani 136, rotated oncefor each vrotation of the shaft 101. rlhis controlling cam has a cam projection 137, which lifts the lever 135, once during each rotation ofthe -shaft and while the lever is lifted the valve-controlled port 129, is opened and this allows a certain amount 'of soda solution to pms down into the wash water.

l pipe 138, leading from the tank 126, for the wash waterconnects with the pipe 139, which in, turn is connected to a steam injector or siphon 140. This steam injector or Siphon 140, isconnected throughl a pipe 141, with steam pipe 119, and thiscon'nec hollow shaft 2, so as to supply the same.

with the w-ash water. It is also connected through the'pipe 145-, with the ipe 51, which supplies the outer surface ofp the can with wash water. 'This pipe 145, .includes a flexible section which permits the'milk can 'to be moved up and down during the washf inv thereof. f V

zThel steam fronifthe pipe 119, entering the steam'v injector 140, draws the wash water from' the tank .126, and conveys the same tothe interior and exterior of the can at the washing station. It will be noted that as long as the steam continues to flow, the can will be subjected to clean washino'- water lboth interiorly and exteriorly.. All the pipes ly below the. table .at the right hand end thereof, is a chamber 146. Air is delivered to this chamber 146 from the pipe 147', which is connected to a blower indicated at Air is taken from the chamber 146', through a pipe 149, which connects with a vertical pipe 150, andthisvertical pipe con`- nects with a manifold 151, extending alongthe side of the machine` A cross pipe 152,

at each drying station, connects with the manifold 151, and each cross pipe has an outlet opening 153, for the can, and an opening 154, .the vertical pipe150, is a valve indicated in dotted lines 155, in Fig. XIII of the drawings. This valve is connected to an arm fbr the c dver. Located within 156 which, in turn is ,connected to a link l157. The link at Iits upper end is pivoted to the' lever 158,l which hasy a lateral pro-v jection 159, adapted to co-operate with the disk 160. This diskhasa cam recess .161, formed therein. The disk 160, ismounted on theshaft 162, kwhich carries the sprocket wheels 102. As the shaft 162, rotates the damper will be intermittently operated r'emaining open while the projection 159, is dropped into the cam recess 161, in the disk 160. When, however, this projection rides on the outer surface of the disk, the damper is closed. l

The endless `conveyer is operated through the rotation'of the shaft 101.'` This shaft carries a clutchone section'of which is indicated at 168. `This section is loose on the .s shaft and carries a wormv gear 164, which `ineshes with the driving worm on the vertical shaft 165. The vertical shaft '165, lcarries the bevel gear 166, at its upper end,

-which meshes with the bevel gear 167, on

y spring 169, normally operates to hold the clutchmembers in engagement. Mounted on the clutch member 168, is a collar 170,`

the side face of whichis inclined as indicated at 171. A rod 172, is mounted in a suitable housing 17 3, and isnormally springp'ressed towards the clutch members, by means of a spring 1711. When the rod is in the position shown in Fig. X1', the clutch members are held' separated and therefore the endless conveyer will be stopped. When the end of the .rod is withdrawn, then the spring 169, will cause the clutch members to intermesh, and the shaft 101, will be rotated. Upon a half revolution vof the shaft'101, the inclined collar willy come to a point where. the rod slides from its outerV face and moves to its extreme inward position. On the nent half rotation of the shaft the rod working against the inclined face of this collar, willforce the outer clutch member back, opening the clutch and stopping the" machine. herefore the manual withdrawing of the rod starts the conveyer but said rod operates normally to automatically stop the conveyer after the shaft 101, has made one complete rotation. The stations for rinsing, sterilizing and drying are so disposed along the table that a single rotation of the shaft 101, ywill center the can over the nozzle first atthe rinsing sta-.

tion, then center the can over `the nozzle at the sterilizing station, when the shaft 101, is making its single rotation. @On the next rotation of the shaft, the can will be moved.

to and centered over the drying outlet, and so on through to the end of the machine. The shaft 16.2, turns in unison 4with the shaft 101. The disk 160, is soA positioned on 'the shaft 162, that when the lconveyer is stopped the projection Y159;, drops into the cam recess, opening the valve, andl permitting the hotair to pass through to the manifold 151. As soon as the conveyer starts, then' this valve is closed, cutting ofi the air until the V'can and cover havebeen positioned at the next drying station. The air is heated inthe chamber 146, by 'a series of steam coils 175, which are connected to steam terasse manifolds 176, and 177. rThe steam manifold 176, is in turn connected through the pige 178', with the intake steam pipe.

he `valve 118,. controlling the steam supply to the injector is operated by a lever 179, which is weighted at 180. This lever at the outer end is connected with a vertical into a locking engagement with the lug, and

holds thel valve open. rlhe rod 172, is piv- 'oted at its outer end to a lever 185. rlhis lever is intilrn fulcrumed at 186, on the frame and at its other end is connected by a link 187, to a hand lever 188, which is ful- `crumed at 189. taid hand lever is formed with a handle 190, whichpis disposed at the front side of the machine, where't is readily accessible. This lever 188, extends through a guide 191, rigid'with a bar 192. lThe bar 192, is pivoted' at 193, and at the outer end is connected 'with the slide 1911,

having a foot piece or treadle 195. Said .bars 192, is also provided hwithajpin. 196, which:

is-adapted to engage-an inclined'plate 197, fixed to the bar 181. By raising the hand lever 188, the rod 172, is withdrawn so as to permit the clutch members to close and the H conveyer to be started. Whether this lever 188, be raised by hand or by the foot piece or treadle 195, the bar 192,r will swing on its pivot 193. The pin 196, moving on the i-noline 197, will force the bar 181, to the left, at the upper end, releasing the same from its lockingengagement, with'fhe lug 183,

and this permits the same to drop, thus closin the valve 118. This ensures that the va ve 118, be closed whenever the conveyer `is started. The valve 118, is opened for washing, rinsing and sterilizing and may remain open, as long as desired, and as long as it is open the washing and rinsing water continue to'flow. As soon however, as it is desired' to move the can to another station, the operator only has to release the rod or bolt which holds the clutch members separated and the conveyer starts at once, and automatically stops when the can is positioned at the next station, and centered over the nozzle at said station. rlhe operator then raises the valve and begins the next washing operation at the washing station. The can is placed over thebrushes and is readily gripped between the holding arms through `the release treadle 50, the spring causing'the arms to close against the can. The can is raised and lowered vthrough the lever 65, and may. be raised-or lowered to a limited extent, without stopping the rota.-

The can may -he quickly removed from the washing apparatus and placed on the table at the rinsing station. The same operation which of the wash water for. the

water and the can and cover on the supporting table are thoroughly rinsed by the Water which is thrown there a ainst by the steam injector or siph'on. y he oonveyer may be quickly started'to move the can on to the next station to make room for the last Washed can, and it will automatically stop when the cans are properly positioned and automatically turns on the drying air for drying the cans at the drying stat1on.. The supplies of steam to 140, and of wash and rinse water and sterilizing steam at the stations W, R, and S, are all vcontrolled in unison by means of the steam valve 118; which .is manually opened to turn them on (independently'of the manual startin of the conveyor) by the means described a ove, and is automatically closed when the conveyor is started. The soda solutionv is fed from the tank 128 to the supply of wash water stored in the tank 126 while the conveyor is in operation, in prepar'ation for the next turning on of the 'wash water for washing a can. The cans and coversare concurrently treated with fluid from beneath durin their progression pari passu 'along the ro s or rails of the track- Wn s by the conveyer.

't is obvious 'that minor changes in the details of construction may be made Without departing from the spirit of the invention as set forth in the appended claims.
