Abstract: A modular, front loading coin operated vending machine with a rotary coin mechanism operating a reciprocating dispensing mechanism dispenses different sizes and quantities of flat merchandise. A back lever arm on the rotary coin mechanism turns with the front coin turning knob and pulls a flexible cable through a grommetted hole in a vertical wall to draw a push plate forward in a chassis slide opening to force a measured size or quantity of the flat merchandise out through a dispensing slot. Shims between the push plate and the sliding plate raise it to vary the size and quantity of merchandise contacted by the push plate. Full width open front merchandise chutes are interchangeably installed A merchandise weight with a bottom protrusion holds down the merchandise. When the merchandise chute is empty the bottom protrusion of the merchandise weight falls into the slide opening to block the push plate from moving forward and preventing the turning of the coin knob.

Abstract: A nail clippings catcher formed from a pre-cut sheet of material having a hole punched through it. This pre-cut sheet preferably extends for some distance on either side of the hole along a fold-line passing through the hole. Folding this pre-cut sheet of material along a fold-line juxtaposes a surface of the sheet with itself. The juxtaposed surface of the sheet is then fastened together while a pocket for receiving nail clippings is concurrently established within the folded sheet. The nail clippings catcher is inserted between the jaws of a conventional nail clipper with the fold-line disposed adjacent to the jaws' cutting edges with the aperture formed through the sheet providing a channel through the folded sheet for the nail clipper's rivet, and an opening for nail clippings to enter and exit the pocket.
