Abstract
Abstract The invention has for object a proportioning device for granulated or pulverulent products, said device is fitted with a spigot cylinder and in which, on the one hand the various spigots are connected to the cylinder on a portion only of their width, so that a ring-shaped section is provided between any pair of adjacent spigots and the cylinder body, the width of this section approximating the active one of each spigot, and in which on the second hand the fixed fingers have a free tip such as to extend through the said ring-shaped sections up to the immediate vicinity of the peripheral surface of the rotating cylinder. The device allows a surely cleaning of the complete cylinder surface.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
150 words
A proportioning device for granulated or pulverulent products comprising a body of a generally cylindrical configuration adapted for rotation within a container housing the granular or pulverulent products, a plurality of radially outwardly directed spigots carried by said body, adjacent ones of said spigots being spaced axially and peripherally with the axial spanning being similar thereby forming peripheral rows of spigots with a peripheral gap between adjacent rows, the cross-sectional configuration of said gaps as viewed in side elevation being defined by the combined configurations of axially adjacent spigots which each include an enlarged terminal head and a reduced connecting neck portion, a plurality of stationary scraping fingers adapted to be fixed to the container housing said granular or pulverulent products, and each finger having a terminal tip within and corresponding in configuration to each of said gaps whereby said gaps are continually self-cleaned during the rotation of said body.
Claim 2
Dependent Claim
150 words
A proportioning device for granulated or pulverulent products comprising a body of a generally cylindrical configuration adapted for rotation within a container housing the granular or pulverulent products, a plurality of radially outwardly directed spigots carried by said body, adjacent ones of said spigots being spaced axially and peripherally with the axial spanning being similar thereby forming peripheral rows of spigots with a peripheral gap between adjacent rows, the cross-sectional configuration of said gaps as viewed in side elevation being defined by the combined configurations of axially adjacent spigots which each include an enlarged terminal head and a reduced connecting neck portion, a plurality of stationary scraping fingers adapted to be fixed to the container housing said granular or pulverulent products, and each finger having a terminal tip within and corresponding in configuration to each of said gaps whereby said gaps are continually self-cleaned during the rotation of said body.
Claim 3
Dependent Claim
28 words
The proportioning device as defined in claim 1 wherein said cylindrical body is a stack of discs with each row of spigots being carried by an associated disc.
Claim 4
Dependent Claim
30 words
The proportioning device as defined in claim 1 wherein said cylindrical body is a stack of discs with each row of spigots being sandwiched between an adjacent pair of discs.
Claim 5
Dependent Claim
26 words
The proportioning device as defined in claim 1 wherein each scraping finger and said gaps are of a generally I-shaped configuration as viewed in side elevation.
Claim 6
Dependent Claim
34 words
The proportioning device as defined in claim 1 wherein each spigot head has radially innermost and outermost surfaces with each innermost radial surface being parallel to an outer peripheral surface of said cylindrical body.
Claim 7
Dependent Claim
19 words
The proportioning device as defined in claim 1 wherein the spigots of at least two rows are circumferentially offset.
Claim 8
Dependent Claim
26 words
The proportioning device as defined in claim 1 wherein each scraping finger and said gaps are of a generally L-shaped configuration as viewed in side elevation.
Claim 9
Dependent Claim
34 words
The proportioning device as defined in claim 7 wherein each row of spigots is defined by a generally flat disc-shaped plate from which project radially said connecting portions and axially said enlarged terminal heads.
