The pin element 41 preferably consists of a screw having a head 47 adapted to bear against the faces yofthe `link atx-the sidesof the slots 48 and 49 and having shanks 50 extending through the slots and threaded into sockets formed in the ends of the rocker arms. V;

Mounted on the base 3 in front of the tank and operating mechanism is a rack 53 preferably comprising spaced rails 54 mounted on vertical'l legs 55 having feet 56 attached to the base by.

screws 57.

f The legs 55 are offset at their upper'ends'in order that the inner faces of the rails 54 may align with the lower inner faces of the legs "to support a basket 58. The basket 58 preferably consistsof U' shaped wires 59 connected at their lower ends by'a wire 60 and at their upper ends by a Wire band 61 forming the rim of the basket.

The rails 54 ofthe rack element are preferably -ar'ed as at 62 at the 'receiving end thereof to form a mouth for guiding the basket into the rack. The basket is dimensioned to receive a Vseries of connected envelope containers 63 of water-proof material such as are disclosed in the application abovereferred to.

When assembling the apparatus the float 22 andvalve 19 are adjusted to maintain a level of liquid inthe tank slightly below the top of the containers carried'inl the iilling rack.

Assuming the parts to be constructed and assembled as described with the float mechanism set to maintain fa fixed level of liquid in the tank below the tops of the containers and with a basket of 'containers in the rack, the operation of filling the containers Yis as follows:A f d With theY nozzles retained in elevated position, by the spring latches, the discharge ends thereof are above the liquid level in the' tank and the lever 5l in retracted position, as illustrated in Figs. 1 and 3.

When the operating lever is drawn forwardly, the rocker arms are moved from engagement with 'j the latches and the nozzlesl are lowered so that the curved ends 29 thereof enter the open ends of the containers. e

In this position the ends of the Anozzles are supported inv fixed lposition below the level of ,liquidin 'the tank due to the fact that the d ends ofthe links 38k and 39 have engaged the base 3, Vas best illustrated in Fig. 4.

Continued forward movement of the lever arm moves the rollers 35 `to engage the bottom of the tank 1 so that thetank is liftedabove its normal position and is guided by the upper ends of the legs to bring the inlet ends of the nozzles above the outlet endsthereof to start gravitational flow of "liquidthrough the nozzles.

e During lifting of the tank by the rocker arms, the opposite ends thereof move inthe slots 48 and 49 until they are stopped by the lower ends thereofA to control the extent of lift of thel tank.

As soon as flow has started from the nozzles,

(e the; lever armv51' is moved retractively toward the tank to lower the tank onits seat, as illustrated in.Fig.5. Y d l -K Flow `then A-continues`- through rthe nozzles by syphonicV action until the level of liquid in the containers equals the level of liquid in the tank whereupon the syphon is broken to interrupt the flow of liquid to the containers.

The'operating lever 51 is then moved to its rstposition to lift the nozzles from the containers and to engage the rollers with the latching members 36, as illustrated-in Figs. l andv 13, causing liquid inthe nozzlesv todrain back into the tank, thereby preventing dripping from the noz- 5l designates a lever arm iixed to the '4 The basket carrying the containers is then re- -moved from the rack and replaced with a basket carrying empty-containers whereup the operating steps are repeatedas'above described.

` It is apparent ,from the foregoing disclosure Y that the level of 4liquid may be varied to correspond with the requirements of containers of different heights by adjustment of the oat valve and that due to syphonie flow the containers :may be. filled from Athe tank without Wastage of the liquid, as there isjno overflowing or splashing of the liq'uid during the llingoperations, because the syphon is broken when the respective levels in the containers are equalized.

VIt is also apparent vthat with the structure illustrated a series of containers, each having different cubical contents, may be filled to the same level during the filling operation. l

While I have described the invention as particularly relating to an apparatus for fllingcontainers' for confections as disclosed in the above mentioned application, it is-obvious'that the'apparatus may be utilized for filling various forms of containers and I do not wish to be limited tothe specific use specied.
