Abstract
Abstract A convertible metering apparatus for dispensing metered quantities of different flowable goods of unlike physical properties comprises a housing defining a material storge chamber therein; a motor; and a drive shaft being rotatably connected to the motor and extending into the housing. There is further provided a metering member adapted to handle a flowable material of a first physical property; a discharge unit configured to receive the metering member therein; and a first releasable connecting arrangement for readily connecting the metering member to and readily disconnecting it from the drive shaft. This arrangement ensures that the metering member is readily replaceable by another metering member adapted to handle a flowable material of a second physical property. The apparatus further has a second releasable connecting arrangement for readily connecting the discharge unit to and readily disconnecting it from the housing, whereby the discharge unit is readily replaceble by another discharge unit configured to receive the other metering member therein.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
167 words
A metering apparatus kit for providing a convertible metering apparatus to dispense metered quantities of different flowable goods of unlike physical properties, comprising (a) a housing defining a material storage chamber therein; (b) a motor; (c) a drive shaft having an axis and being rotatably connected to said motor and extending into said housing; (d) a first metering member adapted to handle a flowable material of a first physical property; (e) a second metering member adapted to handle a flowable material of a second physical property; (f) a first discharge unit configured to receive said first metering member therein; (g) second discharge unit configured to receive said second metering member therein; (h) a first releasable connecting means for readily connecting a selected one of said first and second metering members to and readily disconnecting it from said drive shaft; and (i) a second releasable connecting means for readily connecting a selected one of said first and second discharge units to and readily disconnecting it from said housing.
Claim 2
Dependent Claim
167 words
A metering apparatus kit for providing a convertible metering apparatus to dispense metered quantities of different flowable goods of unlike physical properties, comprising (a) a housing defining a material storage chamber therein; (b) a motor; (c) a drive shaft having an axis and being rotatably connected to said motor and extending into said housing; (d) a first metering member adapted to handle a flowable material of a first physical property; (e) a second metering member adapted to handle a flowable material of a second physical property; (f) a first discharge unit configured to receive said first metering member therein; (g) second discharge unit configured to receive said second metering member therein; (h) a first releasable connecting means for readily connecting a selected one of said first and second metering members to and readily disconnecting it from said drive shaft; and (i) a second releasable connecting means for readily connecting a selected one of said first and second discharge units to and readily disconnecting it from said housing.
Claim 3
Dependent Claim
16 words
A metering apparatus kit as defined in claim 1, wherein said drive shaft is vertically oriented.
Claim 4
Dependent Claim
47 words
A metering apparatus kit as defined in claim 1, wherein each said discharge unit has a discharge opening through which metered flowable material leaves the apparatus; further comprising an openable and closable shutoff gate cooperating with the discharge opening of the discharge unit connected to said housing.
Claim 5
Dependent Claim
18 words
A metering apparatus kit as defined in claim 1, wherein said second metering member comprises a conveyor screw.
Claim 6
Dependent Claim
30 words
A metering apparatus kit as defined in claim 1, wherein said first releasable connecting means comprises a push-in coupling for torque-transmittingly connecting said selected metering member to said drive shaft.
Claim 7
Dependent Claim
18 words
A metering apparatus kit as defined in claim 1, wherein said first metering member comprises a compartmentalized wheel.
Claim 8
Dependent Claim
84 words
A metering apparatus kit as defined in claim 6, wherein said first discharge unit comprises first and second axially spaced discs together bounding a space defined within said first discharge unit and accommodating said compartmentalized wheel when said compartmentalized wheel is coupled to said drive shaft and said first discharge unit is coupled to said housing; said first and said second disc each having a throughgoing aperture; the aperture in said first disc being circumferentially offset relative to the aperture in said second disc.
Claim 9
Dependent Claim
38 words
A metering apparatus kit as defined in claim 1, further comprising an outlet funnel secured to said housing; said outlet funnel being composed of two separable halves having a parting plane containing said axis of said drive shaft.
Claim 10
Dependent Claim
50 words
