COMPANY, OIE: CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS PRERINSING DEVICE FDR BOTTLE WASBERS .Application illed December 10, 1927. Serial No. 239,090.

The invention relates to bottle. washing apparatus, more particularly to a device for subjecting bottles to a preliminaryT rinsing before being subjected to the cleansing treatment.

l The invention is particularly adapted to a bottle-washing Vmachine of the .type represented in Patent No. 1,749,989, granted use with that machine the invention is herein illustrated and described for convenience as a part of or attachment for themachine set forth in the above mentioned application,

Bottle washing machines of the type mentioned comprise an endless conveyor carryin are deposited and are thereby -carried through successive compartments in the ma- .o chine for'soaking treatment by submergence in cleansing solution contained in tanks, the bottles being subsequently subjected to spraying and rinsing treatment. Em ty bottles returned to dairy plants from mi k consumers frequently contain foreign matter and are in such soiled condition that if the bottles were at once introduced into the solution tanks the solution therein would quickly be-l come seriously fouled and greatly reduced in effectiveness. l' A To-avoid this result it is obviously desirable to give the soiled bottles a preliminary rinsing for the removal of the greater portion of such soil and its diversion from the solution tanks before the bottles enter the latter. It isthe principal object of this invention to provide means for subjecting bottles to a pre-rinsingspray'- in machines of the type mentioned, with provision Ifor carrying the cleansing solutions.

Another object is 'to provide such a prerinsing` means 1n connection with an auto-l matic loading'device for depositing bottles discharged rinse water away from the usual of full normal movement thereinto, and thus f prevent jamming of thebottles and damage to the machine. j

A further object is to rovide an automatically interposed stop or arresting bottles within a rinsing chamber, with which stop is associated spraying means forrinsing the bottles, the stop beng withdrawn automati- March 11, 1930, upon the application .of f' .George F. Soelch, and while not limited t0 cally after rinsing to permit the bottles to pass int-o the conveyor pockets.

A further object is to provide means for adjusting the position of the rinsing chambers so that the latter may be accuratelyalined with the conveyor bottle pockets as the latter arer positioned for receiving the bottles. fi

Other objects and advantages will be apparent in the following detaileddescription of a preferred embodiment ofthe invention which has been selected for illustration in the accompanying drawings. It will be understood however, that4 various changes in form and arrangement may be made by those skilled in the artwithout departing from the spirit and sco e of the invention as expressed in the appen ed claims.

Referring to the drawings:

Figure 1 illustrates in side elevation a fractional vportion of the end of abottle washing lmachine similar in structure to that illustrated in the before mentioned copending application, and with which is incorporated the invention herein disclosed. v

Fig. 2 is a cross sectional view in elevation taken on the plane of the line 2 2 in Figure 1.

. Fig. 3 is a longitudinal section of a view in\ chine, is in driving of conventional structure comprising the disk 2, the crank 3 carrying the actuating pin 4 alrlidfhe slotted star wheel 5 mounted on the s a 6.

' The intermittently driven shaft 6, extendl8. 'The chains 8 carry at spaced intervals ing transversely through the `transversely arranged groups of bottle pockets 9 within which the bottles are deposited, as hereinafter described, to be subjected to the washing treatment. The endless conveyor and its series of bottle pockets are moved intermittently through the several stations provided in the machine for the cleansing treatment, the intermittent movement being accomplished by the Geneva device illustrated in Fig. 1.

The foregoing structure is fully described and illustrated in complete detail in the aforementioned patent', and not being a part of the present invention is not further described herein. It will be understood thatin the operation of the bottle conveyor the individual transverse 'groups of spaced bottle pockets are successivel brought to the position illustrated at A in ig. 3 and reina-in at that position during" the interval of arrested movement.

Positioned above andv in axial alinement with the conveyor pockets 9, when in. the position illustrated t A, is a bottle holder 10 comprising a suitable outer wall structure within which is provided a transverse series of chambers 11, each of which is open at the top and bottom and each of which is in register with one of the bottle pockets 9 carried by the conveyor. The chambers 11 are preferably formed by vertical partitions 12 and trough-like bottom wall 13 adapted to receive and guide the bottles introduced into the chambers, as hereinafter described. The bottle holder structure 10 is mainly supported by means of brackets 14 secured to holder and having a Awith the bottle pockets 9 17 rotatabl pins i9 having the upper margin of the lower wall of the loose bearing vupon a shaft :operatively the 'side walls of the washing machine.

Accurate alinement of the chambers 11 in their arrested A, is adjustably mainmeans of a threaded adjustingA bar secured in an oscillating lock with 'laterally extending pivot their bearing in a bracket 20 secured to the lower marginal portion of the uider wall of the bottle holder 10. The adjusting bar1 17` is in intermediate 'screw position, as shown at tained by 18 provideV threaded engagement;v with a bearing collar laterally extending pivot studs 22 'which have bearing support in' a -bar 17 is provide dotted lines in Fig. 3,

a le bracket secured and of supported in bearing. brackets 16 secured upon which are Lasten.

bracket 23 stationarily secured tothe end wall 24 of the washin machine. The adjusting with a hand wheel 25 at its outer end, by which the bar may be manually rotated to effect raising or lowering of the lower end of the bottle holder to accurately register the latter vwith the bottle pockets in'the conveyor.

Mounted in rigid relation to the shaft 15 isa rocking loading plate 26 upon which the bottles are placed by an o erator while in the position indicated in i 1, the plate being provided with trough-h e for individual boltles spaced similarly to the chambers 11 in the bottle holder, and with an end wall-28 for retaining the bottles therein.` The plate 26 is carried by a pair of brackets 29 rigidly secured'to the shaft 15,

.and by the rotation of the latter the plate is elevated to the position represented in whereupon the bottles slide downward into the chambers 11 in the bottle holder.

The rock shaft 15 is operated by means of a crank 30 keyed to the outer end of the shaft and pivotally connected with a link bar 31 (Fig. 1) oppositely pivoted to a lever 32 having an intermediate fulcrum bearing 11 on a stationary stud 33 provided on a suitto the side wall of the machine. The opposite end of the lever 32 extends into the path of movement of the pin 4 carried by the crank 3 mounted on the power shaft 1. The upper end of the lever 32 is of such form that its enga ement by the pin 4 effects the movement o the lever the rock shaft 1 5 so that. the loading plate 26 is elevated to drop the bottles into the bottle holder chambers in synchronous time relation to the intermittent movement of the conveyor bottle pockets into position A to receive the bottles.

This synchronous movement is .obviously maintained by the association of the lever 32 with. the Geneva transmission for the movement of the bottle conveyor. The return movement of the lever 32 may be adjustably limited by means of an' adjustable stop fprovided for abutment by the lower end o the lever and comprising a vstud 34 having screw threaded support/in. a bracket 35 secured to the side wall of the machine,the stud having a, conventional lock the desired position.'

'A substantial space the adjacent endsof the bottle holder 10 and the bottle .pockets 9 provided in the confveyor, wherein is operatively positioned an automatic bottle stop and pre-rinsing mech- The later 'comprisesa series of stop members 36 having segmental circular faces 'ti'oncd respectively at the lower ends of t members 36 areoperatively Y swung upwardly across the'open lower ends supports 27 is provided between so 'y lio nut to secure it in e bottle chambers 11. The stop v supported to be of the bottle chambers 11, and in' that position to provide abutments for the bottles discharged into the chambers from the loading plate 26. Each of the stop members is also provided with a spray jet from whichl A a rinsing liquid is sprayed into the bottles while held in the bottle chambers, the stop l members 36 are secured to a supporting plate 38 extendingtransversely of the lower end ofthe bottle holder.

A tubular bar or pi 39 extends through each of the stop mem ers 36, the tube having a laterall opening within each `of the stop members in communication with a passage terminating in a 'jet orifice 40'- provided in the covering 37 and positioned for registry with the mouths of the bottles when l in abutment with the stop member. A second supporting bar 41 extends parallel to the bar 39 and is secured in the lower portions of the stop members 36 to effect rigidity of the mounting of the series. The supporting tubes 39 and 41 are endwardly secured in a pair of swinging brackets 42 and 43, the latter bein secured uponl stub shafts 44 and 45 havingearing support in a pair of brackets 46 and 47 rigidly secured upon the opposite end walls of the holder 10.

The bracket 43 and stub shaft 45. are of hollow construction, providing a passage therethrough in communication with the tube 39 for supplying a rinsing fluid to the spray orifices in the stop members, thel outer end of the hollow stub shaft 45 being connected through suitable lexible piping 46a with a pressure supply of rinsing fluid. The piping connections` 46 are controlled by an intermittently operated valve 47a (see Fig. 7) which is positioned adjacent the main drive shaft 1. The latter carriesa segmental cam 48 adapted' to operatively engage the stem of the valve 47Y during a portion of a revolution, whereby the spraying jets are operated to spray the bottles only when in upward position before the ends of the bottle chamsition, the troughs 49 in effect bridging the` space between thebottle holder and the bot- A.

tle pockets.

The/stop members and theirisupporting structure are operatively moved into the respective positions described by'means of a pair of cranks 50 mounted on the outer ends of the .respective stub shafts 44 and 45 and pivotally connected respectively with a pair oflinks 51, which latter are pivotally connected to a pair of cranks 52 rigidly secured to the shaft 53 extending outwardly of and having its bearing support in the lside wall of a washing machine. Outwardly of the machinel wall is an operating crank 54 (see Figs. 1 and 2) secured upon the shaft 53 and having a connecting rod 55 pivoted thereto, of which latter the opposite end is pivoted to one arm of a rocking lever 56 having intermediate bearing support upon a stub shaft 57, -mounted upon the side wall ofthe machine. The opposite arm 0f the rocking lever 56 is operatively connected by means of a connecting link '58 with a bellcrank 59 pivotally supported at 60 on the side wall of the machine, and having .a

roller 61 operatively mounted thereon and in operative contact with a cam 62 secure upon the powershaftl.

The cam 62 is of such formation as to causev the movement, through the linkage described, of the stop members 36 upwardly into position for abutment by the bottles in the chambers 11 in synchronism with the lifting of the loading plate 26 forvdischarge ofthe bottles therefrom into the chambers 11, and also to permit the return of the stop members 36 to lowermost position, effected by the spring 63, so that the bottles in the holder chambers are permitted to slide .into the bottle pockets 9 vlhile the latter remain in position to receive t em.l

Itis desirable after the rinsing of the bottles to divert, from the solution tanks provided in the Amachine, the rinse water carrying substances removed from the bottles which flows therefrom at the completion of the rinsing. To this end, a receiving pan 64 (Fig. 3,) is provided beneath the lower ends of the bottle chambers in the bottle holder 10 and suitably supported upon the frame structure of the washing machine, as by brackets 65. The bottles are held within the chambers `for aperiod after the cutting oil'I of the spraying jets, the rinse water draining therefrom into the pan 64 and', by suitable connections with an outlet opening 66, outwardly of the chine inthe event that a bottle should fail topass fully within the conveyor bottle pockets when released from the rinsing chamber-s in the bottle holder. If, for any reason, a bottle should be` arrested in its passage into the i holder and the bottle pockets,

the rinsing mechanism, it is o vious that further-movement of the conveyor would result in `damage to the machine. The safety stop mechanism provided comprises a-rocking bar'67, positioned over the space between the bottle holder and the conveyor bottle pockets by means of a pair of brackets 68 secured to the bar and operatively supporting the latter. The brackets 68 are constructed in the form ofl bell cranks intermediately pivoted on studs 69 mounted in the respective side walls of the ma'chine. One arm of each bell crank supports the bar, the other arm having a bifurcated end 'portion 'carrying a cross pin 70 which is' engaged in a longitudinally arranged slot formedin the end of a crank 71 extending into the bifurcated portion of the crank 68 and rigidly seA cured to the 'shaft 53.' The operating connections just described e'ect the lowering of the bar 67 toward the bottle stop and spraying ,members 36as the latter are swung into upward position for the abutment of bottles admitted to the rinsing chambers.

. It will here be obvious that if a bottle or any portion remains in the space between the or protrudes fromthe latter suiiiciently far to engage any of the rinsing mechanism, the bottlewill be engaged by the bar 67 and eii'ect the stoppage of the movement of the shaft 53. The result of stopping the rotation of the shaft 53 is to release the main driving clutch through which power is transmitted to the machine as al whole, as fully .illustrated and described in Patent No. 1,775,003, grantedSeptember 2, 1930, upon the application of George F. Soelch. and of which the crank 72 (see Fig.

V2) and the pivoted bar 73 are component parts. The space between the holder and the lpockets being clear, the bar 67 swings intol downward position whilethevbottles are retained in the rinsing chamber, and with the reverse movementof the stop members the bar 67 is elevated to permit the free passage of the bottles when released from the chambers11.

The upper ends of the rinsing chambers in the bottle'holder are provided with pivoted enclosures or doors 74, which are pushed upspray wardly of ward by the entering bottles andrest thereupon while the latter are within' the rinsing chambers receiving the spray from the rinsingjet. If, however, a bottle has not been 'placed on the loading plate 26 before any one or more of the chambers, so that with the elevation of the loadingplate n'o bottle is discharged into the chamber, the door 74 remains indownward position and receives the dischargedfrom the rinsing jet, thus the spray from being thrown outthe chamber through the upper preventing end.
