As they face the opening in the machine' front, said bottles fall by gravityout ofthe carrier Aand slide over said baseV member 32, resting in an inclined position 'on thefnfiovable' retainers 31.

Withthe oscillation ofithe'shaft` 29, actuated as hereinbefore described,'the'retainers 31 are moved upwardly. in an `arc byL the-farms 30- until the bot.- tles held rtherein reach al verticall'position'and rest on the conveyor chain 34, from whichlthey are-taken to the llin'gmachines. e I It willfbe noted from Figs. 1, .'2 that the con- `veyorvchain 34'may be actuatedV by al shaft 35 lconnecting with Ychain drive 36, horizontal shaft 37, Aand`vertical-shaft 38, gearedto the pulley shaft 39-in the usual manner (Fig.1). As an 'alternativa'said conveyor chain; may be' actuated by combination Awith the conveyor chain of the filling machine 'and its. actuatingmea'ns.-

When the concurrentv'ejection of cleanbottles from the machine, and feedingof-vdirtylbottles,

is completed, the continued movement of the peripheral cam 13, aided by the spring 40, again returns the fingers 21 and bottle retainers 31 to their operating position.

'AS1 hereinbefore,"pointed.outjduring the interval thatfl the carriers 'and conveyor chains are stationary the soaking draining, brushing and yrinsing operations in the machine are taking place. Y

` With thedownward and forward movement of the.l carriers at the front of themachine, the bottles enterthetank 41 and are lled with hot chemical'solution'.` The solution in the tank is heated'by. the usual means, viz., steam coil, gas flame, etc. and the bottles soak therein with the successive forward movement ofthe carriers until carried around the sprocket or wheel 42 and inverted, when lthe `solutioni remaining in `said bottles is idrai'ri'ed therefrom. This 'drainage is returnedto the tank bylrneans of the drain pan formed by the-*inclined side ofthe tank 41.

-'iUpon-emergingfrom the solution tank 41, the bottles are'ready' for the brushingand rinsing op'ere'ttion's;y ThisI operationrequires that the centering funnels 43 beplacedfinidirect contact with the-mouths fand necks 'of the bottles to be brushed and rinsed,v andithat rinsinfgfand brushingy means be provided f I 1- v- Figures 1 andv Zishow the transverse series of centering 'funnels 43 raised into contact with the bottles, and l'thefrinsing means and brushes in theirnormal position foroperation, the operation thereof being explained as follows.

' -As`theforward movement of the conveyor chains lland carriers' 3 ceases the frame 44 and all its appurtenances including the centering funvlnels '43, which have been lowered during the i movement of the carriers 3, are actuated upwardlyfuntil Ysaid funnels are indirect contact with andaround thefnecksof the stationary bottles to loe-brushed 'andfrinsed v The Aframe 44 and supported attachments above referred to, is arranged to slideverticallyin a `groove between the uprights 51 on each side of the machine', being actuated' by a rocker arm 52 on eachendfpivoted to the frame supporting memfb'er'53, The rocker arms 52 arefkeyed to the shaft 54 extending transversely across the machine and journaled in theframe thereof; and are alsoconne'cted by a similar transverse shaft 55 at the extr'emerear endthereoithe latter shaft/being vertically'movable in a slot 56 in each side of the machine. `Supports 57 depend from said shaft 55 in- Sidel the machine and are jointlypivoted on `the lever58, the opposite (or forward) 'end of said `lever being keyed to the shaft 54 in manner vsimilar-totherockeriarms 52 (see Fig.1). i

` 'I'he catch'basin 86, which receives the drippings from the bottles `during -their brushing and rinsing operations,may be` connected with the sewer by anyconventional type of outlet. n, ,Y It is not to be understood from the foregoing description of my inventionthat I limit it to a machine witha specied number of bottle compartments in the carriers, or to any specified number of spindles 67, funnels 43, brushes 49, or

rinse jets 46. These and other features offmy invention may-vary-with the number of bottles it is desired to accommodate in the machine at lone time.
