Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
178 words
A filler unit comprising a piston pump connected to a supply of liquid, reciprocating means for reciprocating the piston of said pump, said reciprocating means being coupled to said piston by a lever, the arrangement being such that the rate of movement of said piston on the suction stroke is greater than the rate of movement of said piston on the discharge stroke, said lever having a plurality of apertures longitudinally spaced, support means for said lever having a plurality of transverse apertures also longitudinally spaced, a pin constituting a fulcrum for said lever, said pin being adapted for selective positioning in selected apertures in said lever and said support means for varying the fulcrum position of said lever, whereby the stroke of the piston of said pump can be varied to vary the quantity of liquid discharged by said pump, and means on one end of said lever for connecting said lever to said reciprocable means, said connecting means being adjustably movable longitudinally of said lever for finely adjusting the stroke of the piston of said pump.
Claim 2
Dependent Claim
178 words
A filler unit comprising a piston pump connected to a supply of liquid, reciprocating means for reciprocating the piston of said pump, said reciprocating means being coupled to said piston by a lever, the arrangement being such that the rate of movement of said piston on the suction stroke is greater than the rate of movement of said piston on the discharge stroke, said lever having a plurality of apertures longitudinally spaced, support means for said lever having a plurality of transverse apertures also longitudinally spaced, a pin constituting a fulcrum for said lever, said pin being adapted for selective positioning in selected apertures in said lever and said support means for varying the fulcrum position of said lever, whereby the stroke of the piston of said pump can be varied to vary the quantity of liquid discharged by said pump, and means on one end of said lever for connecting said lever to said reciprocable means, said connecting means being adjustably movable longitudinally of said lever for finely adjusting the stroke of the piston of said pump.
Claim 3
Dependent Claim
99 words
The filler unit of claim 1, wherein said reciprocating means comprises a reciprocable rod for rocking said lever about said pin constituting a fulcrum for said lever, a drive shaft, a sleeve fixed to the lower end of said reciprocable rod, an eccentric mounted on said drive shaft, a connecting rod fixed to said eccentric and slidably received in the lower end of said sleeve whereby no motion is transmitted to said reciprocable rod, means for selectively locking said connecting rod to said sleeve to transmit reciprocating motion to said reciprocable rod and said lever to operate said pump.
Claim 4
Dependent Claim
132 words
The filler unit of claim 1, wherein said reciprocating means comprises a reciprocable rod for rocking said lever about said pin constituting a fulcrum for said lever, a drive shaft, an eccentric mounted on said drive shaft, a sleeve fixed on the lower end of said reciprocable rod, said sleeve having a pair of registering elongated slots, a connecting rod fixed to sAid eccentric and slidably received in said sleeve, a pin passing through said connecting rod and said slots and operative on the downward movement of said eccentric to draw said reciprocable rod downwardly to effect a suction stroke by the pump piston, said connecting rod on the upward movement of said eccentric being slidable relative to said sleeve without transmitting corresponding movement to said reciprocable rod and said pump piston.
Claim 5
Dependent Claim
89 words
The filler unit of claim 3, further comprising a pin slidable in said transversely registering apertures, an air cylinder carried on said sleeve and operatively connected to said slidable pin, means for actuating said air cylinder whereby said slidable pin is caused to pass through the apertures of said sleeve and said connecting rod when the same are caused to be moved into registration with each other thereby to lock said sleeve to said connecting rod and to effect transmission of motion from said eccentric to said pump piston.
Claim 6
Dependent Claim
74 words
The filler unit of claim 4, further comprising control means for actuating said air cylinder, said control means having an arm disposed in the path of travel of the cartons to be filled by said filler unit and arranged to be engaged by each of said cartons as said cartons are moved into registration with said filler unit so as to effect actuation of said air cylinder thereby to effect actuation of said pump.
