Abstract

In automatic machinery in which loaded trays of small parts are fed into a machine for serial or batch operation on the small parts, it is essential that the racks or trays be held from inadvertent lateral movement (out of the normal path of travel) and at the same time provide a cover which may be quickly removed so as to free jam-ups, remove spilled parts or pieces and the like. Accordingly, it is essential that the mechanism holding the cover in place be quick acting to facilitate removal of the cover.

Latch

In automatic machinery in which loaded trays of small parts are fed into a machine for serial or batch operation on the small parts, it is essential that the racks or trays be held from inadvertent lateral movement (out of the normal path of travel) and at the same time provide a cover which may be quickly removed so as to free jam-ups, remove spilled parts or pieces and the like. Accordingly, it is essential that the mechanism holding the cover in place be quick acting to facilitate removal of the cover.

In the drawing, a hingeable cover 10 having a quick acting latch mechanism 15 located at one end thereof and a hinge 11 at the opposite end is shown. The catch mechanism 15 includes a plunger 16 which is mounted for reciprocation in a bore 17 in a boss 18 at the one end. The plunger 16 is connected to a latch cam 19, which comprises an axially bifurcated saddle piece between the legs of which passes a latch 20. The latch 20 is slideable transversely of the boss 18 through a hole 21, the latch having a projecting nose 22 thereon for engagement in a slot 23 which holds the cover in position superimposed of, for example, trays. In each leg of the latch cam 19 which embraces the latch 20, is an angled slot 24 which cooperates and registers with a pin 25 extending from opposite sides of the latch 20. A compression spring 26 tends to maintain the latch cam in the position shown. By grasping and pulling on the knob 16A of the plunger 16, the latch cam moves again...
