Abstract
Abstract A machine for automatically filling containers such as ampoules and the like having a circular indexing table for moving the containers through a filling station. A liquid filling device having a discharge nozzle, an adjustable volume metering chamber and a valve controlling the filling of the chamber and the discharging of the liquid to the container through the nozzle. A powder filling device having a reservoir and a nozzle, the powder filling device and the liquid filling nozzle being rotatably mounted for alternative use at the filling station.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
190 words
A fluid filling apparatus for filling containers with a predetermined volume of fluid comprising a housing, a needle-like fluid delivery tube in said housing, means for moving either of said delivery tube and housing relative to each other so that the needle tube projects outwardly of said housing in alignment with the opening of a container to be filled, means for moving either of said container and said tube relative to each other so that the tube is inserted within the container, means for communicating said tube to a supply of a predetermined volume of fluid, means for gradually withdrawing either of said container and tube relative to each other while filling the container, said housing comprising an elongated tube defining an axial bore, a plunger means adapted to slide axially of the bore, said tube being connected at one end of the plunger means, the other end of the tube being adapted to project outwardly of one end of said housing, adapter means connecting the plunger means to a supply line of fluid to be filled, said plunger means containing bore means for communicating the tube to the adapter.
Claim 2
Dependent Claim
190 words
A fluid filling apparatus for filling containers with a predetermined volume of fluid comprising a housing, a needle-like fluid delivery tube in said housing, means for moving either of said delivery tube and housing relative to each other so that the needle tube projects outwardly of said housing in alignment with the opening of a container to be filled, means for moving either of said container and said tube relative to each other so that the tube is inserted within the container, means for communicating said tube to a supply of a predetermined volume of fluid, means for gradually withdrawing either of said container and tube relative to each other while filling the container, said housing comprising an elongated tube defining an axial bore, a plunger means adapted to slide axially of the bore, said tube being connected at one end of the plunger means, the other end of the tube being adapted to project outwardly of one end of said housing, adapter means connecting the plunger means to a supply line of fluid to be filled, said plunger means containing bore means for communicating the tube to the adapter.
Claim 3
Dependent Claim
66 words
A fluid filling apparatus as defined in claim 1, wherein the free end of said delivery tube cooperates with centering means for centering the opening of a container, said centering means including a spring biased collar adapted for limited movement axially of the bore and having a conical cavity flaring outwardly thereof and a passage at the apex of said cavity for passing the delivery tube.
Claim 4
Dependent Claim
49 words
A fluid filling apparatus as defined in claim 1, wherein the plunger means is spring biased to normally urge the plunger means and the delivery tube outwardly axially of the tubular housing and means are provided for gradually retrieving the plunger means and the delivery tube within the housing.
Claim 5
Dependent Claim
45 words
A fluid filling apparatus as defined in claim 1, wherein the housing is fixedly mounted and the delivery tube is movably mounted relative to the housing, said container is movable towards the housing while the delivery tube is movable towards the opening of the container.
Claim 6
Dependent Claim
97 words
A fluid filling apparatus for filling containers with a predetermined volume of fluid as defined in claim 2, wherein a centering tube is concentric with the delivery tube and is adapted for axial movement relative thereto spring biased to said plunger means, the free end of said centering tube includes a centering collar having a conical cavity, a passage at the apex of said cavity for passing the delivery tube whereby said centering collar will shock-absorbingly engage the mouth of a container to be filled as the opening is centered for the insertion of the delivery tube.
Claim 7
Dependent Claim
46 words
An apparatus as defined in claim 5 wherein the fluid to be inserted in the bottle is a gas and a valve means is provided in association with the plunger means to allow a predetermined volume of gas to enter said container through said delivery tube.
Claim 8
Dependent Claim
108 words
An apparatus as defined in claim 6, wherein the valve includes a central bore communicating with the supply of gas and with the delivery tube in the plunger means and plunger type valve means are provided in the valve for controlling the flow of gas from said supply means through said delivery tube and into said container but the valve will be opened by abutment against abutment means as the plunger means is in a downwardly extending position with the delivery tube inserted within the container, said plunger type valve will close the supply of gas as the plunger means and delivery tube are retrieved within the housing.
