riding on top of one another thus eliminating jam up which ultimately would cause interruption of the machine operation such unique means include an elongated generally planar resilient spacer member 30 adapted for insertion inside of the track for altering the space constraints of the delivery path as a function of button thickness more importantly the implant or insert means serves to maintain the disk like objects in the same planar orientation as when they are initially delivered to the spring type track from the vibratory hopper because the insert means extend substantially the length of the button guideway a constant planar orientation of the gravitationally fed objects may be maintained during their delivery to the machine as shown in fig3 the insert means may be provided with a plurality of upstruck generally l shaped tabs 32 the l shaped tabs are spaced at intervals along the length of the spacer and each tab is adapted to engage a wire of the spring chute at least two tabs at each end of the spring may have their openings in opposite directions in assembly the spacer will be inserted into the guide way of the untensioned spring track assembly in such condition the spring track assembly is shorter than the spacer the chute or spring.
