BOTTLE FILLING MACHINE Filed oct.' 22 192;

WITNESSESS INVENTORS ATTORNEYS',

spond, and the diameter of the piston 2O is of such dimension as to snugly fit the same yet permit ready reciprocation thereof. It is also noted that the lower extremities of arms 88 and 39 extend very close to opening l0 but terminate sufiiciently distant therefrom to prevent obstructing the same and the passage of piston 20.

rlhe mechanism for actuating the piston previously described causes it to traverse the entire length of the nozzle 4t2 and to rise a substantial distancer above the opening 40 and the extremities of arms 3S and 39, in order to permit free entry of the material contained in hopper-35 into the nozzle.

The operation of the device is as follows:

The powdered material to be dispensed is placed in the hopper. 35 and the neck of a bottle to be filled is brought into alignment with the nozzle by any suitable means, either automatic r manual, but as such mechanism forms no part of the present invention the same has not been illustrated. Motor 7 drives gears l0 and 11 through the worm 9, gear 11, causing reciprocation of piston by means of crank 12, link 13, cross head 14 and rod 19, While gear 10 rotates sleeve 23, the spider -26 and depending arms 88 and 39.

Arms

38, 39 may be adjusted by actuating the turn buckle so as to secure a setting between the same and the inner surface of the hopper giving the best results and not only prevent the. powdered material from adhering to the side of the hopper but keep the same in an agitated and pulverized condition preventing the particles thereof from cohering and forming agglomerated masses. The material is thus kept in such condition that the finely divided particles do not either stick 'to each other or to the sides of the hopper,

the same liowing freely through the opening 40 into the nozzle 47 whenever the piston 20 rises above the discharge opening and ends of

arms

38, 39 on its upward stroke, the extreme limit of which is indicated by the full lines in the drawings. On the downward stroke of the piston the same positively discharges whatever material has previously entered the nozzle and remains therein. f

In actual practice the piston 20 is caused to reciprocate one or more times after the bottle has been lled with the discharged powder so as to partially pack the same therein, care being taken not to prolong the packing operation to such extent as to subject the bottles to suflicient pressure to cause breakage.

The guard 49 acts as a shroud around the neck of bottle 50 preventing spilling 0r waste of the powder during the filling operation. After the plunger has been reciprocated a sufficient number of times to eliiect the desired filling and packing, and the required number for various sized bottles is determined by experiment, the lilled bottle is removed and an empty one brought underthe nozzle for filling in a similar manner. The lled bottle is replaced by an empty one during the upward movement of piston 20 from the lowest point in its stroke, as indicated in dotted lines, to the discharge opening 40, the said piston during the said portion of its stroke acting as a valve preventing discharge through the nozzle.

By arranging the parts in the manner described a very compact device 1s provided in which a single drive shaft actuates both means for rotating the wiper and agitator arms as well as reciprocating the discharge piston and in which parts of the former aid in accurately guiding the reciprocating c plunger. It is thus seen that the device described provides a simple, inexpensive and highly eiiicient construction for the purpose intended.
