A filling machine which in its original construction includes a first number of filling units and which is adapted to be converted into a filling machine with a second number of filling units greater than the first number; to that end the actuating drives of two filling units on the same side of the machine are interconnected by the use of a linking bar detachably mounted over the eccentrics thereof while bearing sleeve housings and bearing bushings are detachably secured on the linking bar in a predetermined number and at predetermined locations for installing thereon the lower ends of the filling units; the pump post mounting members for the upper ends of the respective filling units are removed and in lieu thereof an upper mounting bar is fastened to the filling machine by the use of the same threaded holes in the filling machine which were originally used for fastening the pump post mounting members; the upper mounting bar is provided with a number of pump post members detachably secured thereto which correspond in number to the predetermined number and which are so located on the mounting bar that the upper ends of the filling units can be pivotally secured thereon.
A filling machine, for a predetermined number of filling units mounted thereon, each including pump means having two ends, one of which is actuatable, each pump means comprising pump cylinder means and pump piston means connected with piston rod means, and separate actuating drive means on the same side of the machine for the filling units of the same side, characterized in that for purposes of increasing the number of filling stations on the same filling machine, the respective separate drive means of the same side are drivingly interconnected by a linking bar carrying a predetermined number of bearing sleeve means corresponding in number to the desired increased number of filling units to be used on the same side, a mounting bar detachably connected with said filling machine and carrying a number of pump post means corresponding to said increased number, and the linking bar and its bearing sleeve means being all actuated in unison by the thus interconnected separate drive means, whereby the number of filling units can be increased to said predeterimed increased number by operatively connecting one end of each filling unit to a corresponding pump post means on the mounting bar and the other actuatable end thereof to a corresponding bearing sleeve means.
A conversion kit for converting a filling machine having a first number of filling units into a filling machine with a second number of filling units larger than said first number substantially without change in the machine itself, characterized in that said converter kit includes two bars for at least two original filling units which are to be increased in number, one of said bars being a linking bar for detachably interconnecting separate drive means for the two original filling units and carrying a number of bearing sleeve means corresponding to said greater number to thereby enable actuation in unison of said greater number of filling units, the other bar being a mounting bar to be detachably secured on said filling machine and carrying a number of pump post members corresponding to said greater number, said bearing sleeve means and pump post member being so spaced on the respective bar as to enable installation of said larger number of filling units between respective pump post members and bearing sleeve means while enabling simultaneous actuation thereof.
A method for converting a filling machine having a first number of original filling units mounted at one end on support means and drivingly connected at the other with separate drive means, into a filling machine having a second number of filling units greater than said first number, comprising the steps of disconnecting the original filling units from their respective drive means and disassembling the same from their support means, removing the original support means, interconnecting separate drive means by a linking member carrying a number of bearing sleeves equal to the second number of filling units, detachably connecting to the machine in lieu of the mounting support means at least one bar carrying a number of mounting members equal to said second greater number, and operatively connecting opposite ends of a respective filling unit to a corresponding mounting member and bearing sleeve, whereby a number of filling units equal to said greater number can be installed on said machine and driven in unison by said linking member.
