Abstract: A box construction is provided which enables a box to be assembled from a pre-cut form in which when assembled includes means for locking the top sections together in such fashion that, if an attempt is made to open the box in an unauthorized manner, the attempt at pilferage will be readily apparent.

Abstract: A sewing machine feeder system includes a fluid powered clamp assembly which applies tension to the plies of material being pulled into the needle of a sewing machine by the feed dogs, with more tension being applied to the lower ply of material. The effective point of application of the tension to the plies of material is offset to the left from the line of pull of the feed dogs which causes the plies of material to tend to turn in a counterclockwise direction into a vertical guide, and the plies of material are maintained in a flat and unwrinkled configuration against the vertical guide so that the plies of material hold themselves properly aligned from the guide to the needle of the sewing machine.

Abstract: A box construction is provided in which the top closure of the box is secured to each of the side walls in such a manner that once the top has been secured in place, it cannot be moved to an open position without such damage to the box that this is readily apparent. In this way, any attempt at pilferage is readily ascertained.
