Abstract: A box closure is provided for holding flaps of a box in their downward closed position. The box closure is in a general “H” shape, slides in from one side with a connector which fits in the slot between opposing flaps of a box. The box closure is operative in combination with the box and provides for holding of labels used to identify box contents. The box closure is formed with a single sheet of folded plastic material which is folded to achieve its final shape.

Abstract: An attachment is provided for a high speed low torque rotary power tool for conversion to a low speed high torque reciprocating linear motion so that the power tool can be used with a reciprocating saw blade, file or cutting tools. The attachment is driven by the chuck on the output shaft of the power tool and clamps directly on the power tool housing.

Abstract: A rotary set on a shaft fluid power coupling which may be used on a package wrapping machine is disclosed. The coupling is shown in FIG. 14 of the drawings.The coupling has a first member having a central bore through which a rotary main shaft passes, and is characterized by a face which lies in a plane perpendicular to the shaft which has a cylindrical annular groove therein. A passage within said first member permits fluid to flow to said annular groove. The coupling has a second member which rotates with respect to said first member, and has a face which lies in a plane perpendicular to the main shaft axis of rotation. The second member also has a cylindrical annular extension which extends into said first member cylindrical annular groove. Fluid is passed from the annular space formed between said annular groove and said annular extension to a second member second face which has a fluid passage way connecting means.

Abstract: An apparatus and method for supplying thin film plastic web materials to a wrapper machine as shown and described. This apparatus includes feed stripper which assures the separation of the web material from the apparatus. The feed stripper includes a clamp feed and either a belt roller for stripping or a stripper bar for stripping the film off. An anti-static bar is used to eliminate static electricity on the web material.

Abstract: A package wrapping machine which has a frame supporting a power driven rotary horizontal shaft with a turret plate member on the end of the shaft supporting spaced clamp banks, a positioning blade is placed between the said clamp banks for positioning the package components prior to clamping, a stack of package components is clamped between the clamp banks by fluid power cylinders on the turret plate moving one clamp bank toward the other. The end of an elastoplastic wrapping or web extending from a clamp roll on the frame is moved under one clamp bank by insertion of the packages to be wrapped into position.
