' This invention is a division of the invention set forthv in my patent application for method of and a paratus for packaging; and the roduct t ereof, filed June 25, 1926, Serial o. 118,440. i

' Among the severai objects pf the invention may be noted the provisionaof a filler mechanism for ether, whereby" an accurate charge may be delivered to cans or the like which Fig:4 is alateral section pf the Referring no w more 1 Il, this illingmechamsnr pass the ller; the provision ofI a llerofthe v The box 153 is arranged above means ivhich are adapted to bring 4packages or cans N successively to said boxv 153 and lift said cans N so as to engage a snout 197 onthelbox 153 f for the purpose tobe set out hereimf After the cans have been filled by the present mechanism, they are caused to descendv and ments of the packages being automatically effected. l

The ether cws steadily into the box 153` from an inlet 155 and 'passes to an overflow 157 An axle 159, supported laterally of the box 153, rotatably carries two spaced plates` be taken away -from the `box 153, themove'-` class described including adjustment :features V161. These plates 161 are providedwith cross e5 to compensate for the e ture occur; and the provision of a device of the class' described `which 'is com act and rugged in construction.

Normally the dippers 135 are permitted to bang substantially vertically from their axles 163, and as they dip into the charge of fluid, these dippers are filled (the plates 161 rctating counter-clockwise, Fi 2, by means of mechanism to be describe A deliverftrougb 175 is monnted JWit-lain the box 153 and is adapted to carry Aiinid out through-the bottom o said box to a point centrally above the position offrest for the f cansN as they'arel 'successively brought Ato the filler.l Therefore, in` order to. empty the dippers into the trough 175, there is provided a stationary cam 177 adapted to engage the fol- 1'owers173asthe clippers move to 'a point 'above' said trougl 1715.- By each` 'dpperisrotated andcausedto illits' 95 'i-D their() ,and este@ ro er 173 leaves f the action 'offgravity- A .suitable buer 17 9 s -is* provided for preventingexcessive oscillathe cam 177, e respective clipper-takes up its jorigin'nl'substantally vertical position under tions of the dippers as they return to their normal vertical positions.

In order to adjust the amount (volume) of fluid that each dipper will pick up there is provided a gauging track or cam 181. This is swung from a rotatable support 183 hung from said shaft 159, and is supported by' an adjustable slide `clamp 185. The clamp 185 is operable to be tightened and loosened from a wheel 186. v

In order to regulate the position of the cam 181, after it is unclamped, there is provided therewith a connecting rod 187, to which is pinned a crank 189 held to a control shaft 191. The control shaft 191 carries a wheel 192 or the like for making adjustments. The crank 189 is used to set the cam 181 in any of its various positions.

The cam 181 is adapted by a given particular position, to regulate the positions at which the dippers 165 emerge from the fluid. This is because the followers '173 cooperate with the edge 193 of the cam 181. The changeable positions of the dippers are proportional to the change in position of the cam, and the amount (volume) that each dipper will hold depends upon this positioning. This is evident when it is noted that the level in each dipper depends upon the relative'level of the lip 169 with respect to the dipper. By the above means a redetermined weight is always deliverable gom each dipper. Fig. 2-shows a solid line and an alternatedotted line position of the cam 181 and shows the veffect had upon the dippers when` said cam is re-positioned.

In the present embodiment eight dippersl are used. Outside of the box 153, on the shaft 159, is rovided an eight lobed ratchet, 195, adapte to drive the shaft and the plates 161 in a counter-clockwise direction (Fig. 1).l A cam shaft C which is part of a linkage adapted to move the cans N so las to have certain other operations performed onthem, as `Wella-s to move them into ,cooperation .with

the snout or nozzle 197 is operatedin a clockwisedirection.. i The exact extraneous funcfilled) beneath thesnout 197 of theA trough 175. It also results in Asaid packva'ge'beingl tions ofthe cam shaft C are more particularly set out in the parent application to this ap lication, referred to above.

l h revolution of the cam shaft C results in advancing a package or can N (to be lifted into coo ration with said snout after the last prece 'ngpackage vhas been lowered and carried away. Insofar as this is the action of the cam shaft C,`it is'desirable to emply one of the'dippers- 165 into said trough to said package, each timethat the camv shaft C revolves once. j

In orderto accomplish the above urpose a cam 131 on the cam shaft G is previ ed with apleripheral lobe 199 adapted to oscillate a be -crank lever 201. A connecting rod 203 of the filler.

with the follower as the dipper emer 4 the liquid, and means for maintaining said links the bell-crank lever 201 with a rocker arm 205 rotatably supported on the shaft 159 The rocker arm 205 carries-a pawl 207 adapted to engage the notches of the ratchet 195, and to drive said ratchet ahead one notch for each revolution of the cam shaft C. By this means one filling v The operation is believed to be clear from the foregoing. lThe cams are automatically iilled as they are brought to the given point beneath the snout 197. kThe liquid level Q is maintained because of the overllow feature.

When the temperature changes so that the unit weight of ether changes, this change in unit weight is compensated for on a total Weight basis by changing the volume, through adjustment of the wheel 186. Hence it is a relatively simple matter to maintain a substantially constant weight of total charge in each package.

In view ofthe above, it will be seen that the several objects of the invention are achieved' and other advantageous results attained.v

As many changes could be made in carrying out the above constructions without departing from the scope of the invention, it is intended that all matter-contained in the above description or shown in the accompanying drawings shall be interpreted as lillustrative and not in a limiting sense.
