Bakery mix dispenser having pump actuated outlet gate

Claim 2

A dispensing device for dispensing a bakery mix from a mixing bowl having a discharge port, the device comprising: (a) a dispensing chamber disposed below the discharge port and including a dispensing port, (b) means connecting the discharge port and the dispensing chamber, (c) plunger means mounted in the dispensing chamber, (d) actuating means moving the plunger means in the dispensing chamber to operatively dispense mix from the dispensing port during a dispensing stroke, and (e) the actuating means including piston and cylinder means said piston being operatively connected to the plunger means, and means moving said piston and said plunger means toward and away from the dispensing port said means including valve means manually actuated to supply air to the cylinder to move the piston in one direction and actuated by operative engagement with the piston to supply air to the cylinder to move said piston in the other direction.

Claim 3

A dispensing device as defined in claim 1, in which: (f) the actuating means includes manually operated switching means and said valve means is provided by slide valve means having one end operatively engageable by said switching means and the other end operatively engageable by said piston for selectively routing pressurized air to either side of the piston.

Claim 4

A dispensing device as defined in claim 1, in which: (f) the actuating means includes adjustable limit means carrying the valve means and selectively predetermining the limit of travel of said piston within said cylinder.

Claim 5

A dispensing device as defined in claim 3, in which: (g) the limit means carrying the valve means includes a stop means slidingly mounted in the cylinder and operatively engageable by said piston, and means operatively adjusting and fixing the position of said stop means.

Claim 6

A dispensing device as defined in claim 3, in which: (g) the limit means includes calibrated means movable relative to the cylinder to provide visual indication of the predetermined limit of travel of said piston.

Claim 7

A dispensing device for dispensing a bakery mix from a mixing bowl having a discharge port, the device comprising: (a) a dispensing chamber disposed below the discharge port and including a dispensing port, (b) means connecting the discharge port and the dispensing chamber, (c) plunger means mounted in the dispensing chamber, (d) actuating means moving the plunger means in the dispensing chamber to operatively dispense mix from the dispensing port during a dispensing stroke, (e) the dispensing chamber being substantially horizontal and the dispensing port including gate means transversely disposed of said chamber, (f) the gage means being spring biased into a closed position, said bias being overcome by pressure from the plunger means through the medium of the mix when the plunger means moves toward said gate means during the dispensing stroke, and (g) said gate means including positive closing means operatively engageable by the plunger means at the end of the dispensing stroke to close the gate means independently of the spring bias.

Claim 8

A dispensing device for dispensing a bakery mix from a mixing bowl having a discharge port, the device comprising: (a) a dispensing chamber disposed below the discharge port and including a dispensing port, (b) means connecting the discharge port and the dispensing chamber, (c) plunger means mounted in the dispensing chamber, (d) actuating means moving the plunger means in the dispensing chamber to operatively dispense mix from the dispensing port during a dispensing stroke, (e) the dispensing chamber being substantially horizontal and the dispensing port including gate means transversely disposed of said chamber, (f) the gage means being spring biased into a closed position, said bias being overcome by pressure from the plunger means through the medium of the mix when the plunger means moves toward said gate means during the dispensing stroke, and (g) said gate means including positive closing means operatively engageable by the plunger means at the end of the dispensing stroke to close the gate means independently of the spring bias.

Claim 9

A dispensing device for dispensing a bakery mix from a mixing bowl having a discharge port, the device comprising: (a) a dispensing chamber disposed below the discharge port and including a dispensing port having gate means, (b) means connecting the discharge port and the dispensing chamber, (c) plunger means mounted in the dispensing chamber, (d) actuating means moving the plunger means in the dispensing chamber to operatively dispense mix from the dispensing port during a dispensing stroke, (e) the gate means being biased into a closed position, said bias being overcome by pressure from the plunger means through the medium of the mix when the plunger means moves toward said gate means during the dispensing stroke, and (f) said gate means including positive closing means operatively engageable by the plunger means at the end of the dispensing stroke to close the gate means independently of the bias.

Claim 10

A dispensing device for dispensing a bakery mix from a mixing bowl having a discharge port, the device comprising: (a) a dispensing chamber disposed below the discharge port and including a dispensing port having gate means, (b) means connecting the discharge port and the dispensing chamber, (c) plunger means mounted in the dispensing chamber, (d) actuating means moving the plunger means in the dispensing chamber to operatively dispense mix from the dispensing port during a dispensing stroke, (e) the gate means being biased into a closed position, said bias being overcome by pressure from the plunger means through the medium of the mix when the plunger means moves toward said gate means during the dispensing stroke, and (f) said gate means including positive closing means operatively engageable by the plunger means at the end of the dispensing stroke to close the gate means independently of the bias.

Claim 11

A dispensing device for dispensing a bakery mix from a mixing bowl having a discharge port, the device comprising: (a) a dispensing chamber disposed below the discharge port and including a dispensing port, (b) means connecting the discharge port and the dispensing chamber, (c) plunger means mounted in the dispensing chamber, (d) actuating means moving the plunger means in the dispensing chamber to operatively dispense mix from the dispensing port during a dispensing stroke, and (e) the actuating means including piston and cylinder means said piston being operatively connected to the plunger means, and means moving said piston and said plunger means toward and away from the dispensing port said means including valve means for supplying air to the cylinder to move the piston in either direction and including adjustable limit means connected to the valve means for movement therewith and slidingly and non-rotatively mounted in the cylinder for predetermining the limit of travel of said piston within said cylinder.

Claim 12

A dispensing device for dispensing a bakery mix from a mixing bowl having a discharge port, the device comprising: (a) a dispensing chamber disposed below the discharge port and including a dispensing port, (b) means connecting the discharge port and the dispensing chamber, (c) plunger means mounted in the dispensing chamber, (d) actuating means moving the plunger means in the dispensing chamber to operatively dispense mix from the dispensing port during a dispensing stroke, and (e) the actuating means including piston and cylinder means said piston being operatively connected to the plunger means, and means moving said piston and said plunger means toward and away from the dispensing port said means including valve means for supplying air to the cylinder to move the piston in either direction and including adjustable limit means connected to the valve means for movement therewith and slidingly and non-rotatively mounted in the cylinder for predetermining the limit of travel of said piston within said cylinder.
