Abstract
Abstract A bottle filling machine having a rotatable head containing reservoir with a plurality of downwardly extending bottle engaging filling mechanisms is provided with a tappet vertically slidable in the head adjacent each bottle filling mechanism. Each tappet is provided with a prehensile bottle gripping device at the lower end thereof for gripping a bottle and a curved cam plate is provided for raising each tappet and the bottle held thereby to the bottle filling position whereupon the latch pin will be moved into engagement with a bore in the tappet to hold the tappet and bottle in filling position without the assistance of the cam plate. Upon completion of the filling operation the latch is released to allow the filled bottle to be lowered under the influence of gravity.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
118 words
A bottle filling machine comprising a continuously rotating head having a reservoir therein, a plurality of bottle filling means mounted on said head in controllable communication with said reservoir, a tappet slidably mounted in said head adjacent each bottle filling means, prehensile bottle gripping means secured to the lower end of each tappet for gripping and supporting a bottle, cam means mounted on said bottle filling machine for engagement by said tappet upon rotation of said head to raise said tappet and the bottle carried thereon into filling position in contact with said valve means and latch means selectively engageable with each tappet for maintaining said tappet in the elevated position during the filling operation of each bottle.
Claim 2
Dependent Claim
118 words
A bottle filling machine comprising a continuously rotating head having a reservoir therein, a plurality of bottle filling means mounted on said head in controllable communication with said reservoir, a tappet slidably mounted in said head adjacent each bottle filling means, prehensile bottle gripping means secured to the lower end of each tappet for gripping and supporting a bottle, cam means mounted on said bottle filling machine for engagement by said tappet upon rotation of said head to raise said tappet and the bottle carried thereon into filling position in contact with said valve means and latch means selectively engageable with each tappet for maintaining said tappet in the elevated position during the filling operation of each bottle.
Claim 3
Dependent Claim
55 words
A bottle filling machine as set forth in claim 1 wherein each tappet is provided with a transverse bore extending therethrough perpendicular to the longitudinal axis of said tappet and said latch means is comprised of a latch pin slidably mounted in said head for horizontal movement into and out of engagement with said bore.
Claim 4
Dependent Claim
46 words
A bottle filling machine as set forth in claim 1 wherein said cam means only engages each tappet during the raising operation of each tappet whereby each tappet will be supported only by said latch means once it is moved to its raised bottle filling position.
Claim 5
Dependent Claim
39 words
A bottle filling machine as set forth in claim 3 further comprising means on each tappet for engagement with said head to limit the lowering of each tappet under the force of gravity upon release of said latch means.
