A particulate material dispenser comprising an elongate, vertically extending body defining an upwardly opening material holding compartment, an elongate, laterally extending semi-cylindrical chamber at the bottom of the body and opening upwardly into the compartment and an elongate, laterally extending vertical discharge opening with front, rear and end edges at the bottom of said chamber, an elongate rotor with a plurality of circumferentially spaced, longitudinally extending, radially outwardly projecting webs with outside edges and defining a plurality of circumferentially spaced radially outwardly opening material receiving and transporting pockets of predetermined volume, is positioned in and extends longitudinally of the chamber with the outside edges of two adjacent webs at the lower half of the rotor in sliding sealing engagement with the inside surface of the chamber adjacent the front and rear edges of the opening and with the pocket therebetween communicating with the opening, a spring is positioned in the compartment above the rotor to normally yieldingly urge the rotor down in the chamber, a drive is provided to intermittently move the spring, turn the rotor and sequentially advance the pockets into and out of communication with the opening.

CM,1. A particulate material dispenser comprising an elongate, vertical body with front, rear and side walls, a bottom wall and defining an upwardly opening material holding compartment, an elongate, laterally extending semicylindrical chamber at the bottom wall and opening upwardly into the compartment, an elongate, laterally extending vertical discharge opening with front, rear and end edges at the bottom of said chamber, an elongate rotor with a plurality of circumferentially spaced, longitudinally extending, radially outwardly projecting webs with outside edges and defining a plurality of circumferentially spaced radially outwardly opening material receiving and transporting pockets of predetermined volume, said rotor is positioned in and extends longitudinally of the chamber with the outside edges of two adjacent webs at the lower half of the rotor in sliding sealing engagement with the inside surface of the chamber adjacent the front and rear edges of the opening and with the pocket therebetween communicating with said opening, spring means normally yieldingly urging the rotor down in the chamber and intermittently operable to rotate the rotor to sequentially advance the pockets into and out of communication with the opening and including an elongate spring positioned above the rotor and having a lower rear end in driving engagement with a trailing side of a substantially upwardly projecting leading web, a forward portion engaging the outside edge of a next trailing web, an intermediate portion releasably engaging the outer edge of said leading web and yieldingly urging the rotor down in the chamber and an upper portion, drive means connected with the upper portion and operating to move the spring forwardly and to move its rear end from engagement with said leading web into engagement with said trailing web and to move the spring rearwardly and drive said trailing web rearwardly and rotate the rotor to move the pocket rearward of and adjacent the pocket communicating with said opening into communication with said opening.
