Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
339 words
Apparatus for use in dispensing a composition provided by the mixing together of at least three constituent compositions and comprising: first storage means for containing a first of said constituent compositions; second storage means for containing a second of said constituent compositions means for mixing constituent compositions; first and second cylindrical chambers of different diameters and having pistons slidable therein in one direction to feed one composition from the first storage means to the first chamber while The other composition is fed from the second chamber to the mixing device, said pistons being slidable in the opposite direction to reverse the actions of the chambers; correlating means comprising a pivoted member connected to the pistons and means connected to said member between the connections for said pistons for operating said member to operate the pistons alternately in said directions, the ratio of the distances between the respective connections of the pistons of the first and second chambers and the connection for the operating means being equal to the inverse ratio of the diameters of the respective first and second chamber, the relation of said connections to the pivot of said member being so arranged as to cause the pistons to feed a predetermined ratio of said first and second compositions; third stage means for containing a third constituent composition, a third cylindrical chamber of predetermined diameter having a piston slidable therein in one direction to feed the third composition from the third storage means to the third chamber while one of the other compositions is fed from its chamber to the mixing device said third pistons being slidable in the opposite direction to reverse the action of its chamber, said third piston connected to said correlating intermediate said first and second pistons and co-linearly with said operating means, the realtion of said third piston connection to said correlating member being such that action of said third chamber and piston is independent of the spacing of the first and second chambers and piston and directly depending upon said operating means.
Claim 2
Dependent Claim
339 words
Apparatus for use in dispensing a composition provided by the mixing together of at least three constituent compositions and comprising: first storage means for containing a first of said constituent compositions; second storage means for containing a second of said constituent compositions means for mixing constituent compositions; first and second cylindrical chambers of different diameters and having pistons slidable therein in one direction to feed one composition from the first storage means to the first chamber while The other composition is fed from the second chamber to the mixing device, said pistons being slidable in the opposite direction to reverse the actions of the chambers; correlating means comprising a pivoted member connected to the pistons and means connected to said member between the connections for said pistons for operating said member to operate the pistons alternately in said directions, the ratio of the distances between the respective connections of the pistons of the first and second chambers and the connection for the operating means being equal to the inverse ratio of the diameters of the respective first and second chamber, the relation of said connections to the pivot of said member being so arranged as to cause the pistons to feed a predetermined ratio of said first and second compositions; third stage means for containing a third constituent composition, a third cylindrical chamber of predetermined diameter having a piston slidable therein in one direction to feed the third composition from the third storage means to the third chamber while one of the other compositions is fed from its chamber to the mixing device said third pistons being slidable in the opposite direction to reverse the action of its chamber, said third piston connected to said correlating intermediate said first and second pistons and co-linearly with said operating means, the realtion of said third piston connection to said correlating member being such that action of said third chamber and piston is independent of the spacing of the first and second chambers and piston and directly depending upon said operating means.
Claim 3
Dependent Claim
45 words
Apparatus according to claim 1 including means to adjust the distance between said pivot and the connection of the operating means for varying the ratio of said first and second compositions fed by the pistons and maintaining constant the quantity of the third composition fed.
Claim 4
Dependent Claim
36 words
Apparatus according to claim 2 including means to vary the extent of movement as said correlating member varying the total quantity of compositions fed and maintaining constant the ratio of the first and second quantities fed.
Claim 5
Dependent Claim
182 words
Apparatus for use in dispensing a composition provided by the mixing together of at least three constituent compositions and comprising first feeding means operable to feed a first of said constituent compositions and comprising a cylindrical chamber having a piston slidably disposed therein; second feeding means operable to feed a second of said constituent compositions and comprising a cylindrical chamber having a piston slidably disposed therein; third feeding means operable to feed the third of constituent compositions and comprising a cylindrical chamber having a piston slidably disposed therein, said cylindrical chambers being of different diameters; correlating means controlling the operation of the first and second feeding means according to an operating ratio equal to the inverse ratio of the diameters of the first and second cylinders and controlling the operation of said third feeding means independent of the ratio of said first and second means, said correlating means being adjustable for varying the effectiveness of said operating ratio to vary the quantities of the first and second of the constituent compositions fed and maintaining constant the quantity of the third composition fed.
Claim 6
Dependent Claim
182 words
Apparatus for use in dispensing a composition provided by the mixing together of at least three constituent compositions and comprising first feeding means operable to feed a first of said constituent compositions and comprising a cylindrical chamber having a piston slidably disposed therein; second feeding means operable to feed a second of said constituent compositions and comprising a cylindrical chamber having a piston slidably disposed therein; third feeding means operable to feed the third of constituent compositions and comprising a cylindrical chamber having a piston slidably disposed therein, said cylindrical chambers being of different diameters; correlating means controlling the operation of the first and second feeding means according to an operating ratio equal to the inverse ratio of the diameters of the first and second cylinders and controlling the operation of said third feeding means independent of the ratio of said first and second means, said correlating means being adjustable for varying the effectiveness of said operating ratio to vary the quantities of the first and second of the constituent compositions fed and maintaining constant the quantity of the third composition fed.
Claim 7
Dependent Claim
95 words
Apparatus as set forth in claim 4 wherein said correlating means comprises a pivoted member movable about a pivot and connected to the three pistons, and further including operating means for moving said pivoted member about its pivot and connected to said pivoted member between the said first and second piston connections to said pivoted member and co-linearly with said third piston, the ratio of the distances between the connections of the first and second pistons and the operating means being equal to the inverse ratio of the diameters of the first and second chambers.
Claim 8
Dependent Claim
47 words
Apparatus according to claim 5 including means to adjust the distance between saId pivot and the connection of the operating means for varying the ratio of the respective quantities fed by the first and second feeding means and maintaining constant the quantity of the third composition fed.
Claim 9
Dependent Claim
43 words
Apparatus according to claim 5 including means to vary the extent of movement of the pivoted member for varying the total quantity of the compositions fed and maintaining constant the ratio of the respective quantities fed by the first and second feeding means.
