10 Claims.

'I'his invention relates to a tool for closing wirebound boxes. ,l

It is an object of the invention to provide a tool which will eiliciently and rapidly effect a closure of loop ends of box-binding wires.

It is a further object of the invention to provide a tool which will not unduly strain the wire during a closing operation.

It is a further object of the invention to provide a tool which will effect an eiiicientr closure without damaging either the contents or the container. i

It is a further object of the invention to provide a tool of the character described which will automatically draw or force the lid or cover of the box into closed position.

In the drawings:

Figure 1 is a side elevation of the illustrative tool, with the parts in normal position to start a box closing operation.

Fig. 2 is a side elevation partially sectioned, showing the position of the parts after the box lid or cover has been forced down to closed position and the U-shaped fastener on the lid or cover has been bent down against the front side of the box.

Fig. 3 is a side elevation viewed from the left in Fig. 1.

Fig. 4 is an enlarged sectional view of the means for releasably holding the parts in the normal position shown in Fig. 1.

Fig. 5 is a perspective viewof a wirebound box showing the top section partially closed and in position to be operated upon by the tool of this invention.

Fig. 6 is an enlarged side elevation of a corner of the box of Fig. 5, showing the tool at the start of a closing operation.

Fig. '7 is a similar side elevation after the tool has contacted the top fastener, forced the top section down, and bent the top fastener down toward the face of the front section of the box.

Fig. 8 is a similar side elevation after the tool has been swung down to bend the front-section fastener over the top-section fastener to effect a hooking engagement between the two fasteners and secure the top section in closed position.

Fig. 9 is a side elevation of the corner of the box showing how the closure may be pressed toward the box by the steel ferrule on the handle of the tool.

Fig. 10 is a perspective view of the box corner showing the finished closure.

As conducive .to a better understanding of this Lnvention, it should be noted that in wirebound (Cl. 14o- 123) boxes of the type shown in Fig. 5 the lid or cover section is hingedly connected to the rear section by the binding wires and may be raised or lowered like the lid of a trunk. The lid or cover section is secured in closed position by hooking the wire loop fasteners on the front section through the wire loop fasteners on the cover section as shown in Fig. 10.

When the box is used for the'shipment of commodities such as fruits or vegetables, which have a tendency to settle during storage or transit, it is the practice to overload the box initially so that when the commodity settles, the box will still be substantially full. Great diillculty has been encounered in closing the lid of such an overloaded box prior to hooking the loop fasteners together. In some instances a power press has been used. In other instances the operator has been obliged to press the lid down by hand or with his knee and hold it down while hooking the loop fasteners together.

The tool of this invention is intended to perform the hooking operation and at the same time force down the lid of the box, thus reducing the time and labor required to-close the box and contributing to a uniformly tight closure.

Referring to Fig. 1, a head I supports the several elements of the tool. Extending downwardly from the head I is a round shank 2 terminating in a fiat reduced portion 3 provided with a hook 4. Mounted to slide vertically in a lateral recess 5 in shank 2 is a rod 6, on the lower extremity of which is formed a notch I shaped substantially like an inverted U. The upper end of rod 6 is fixed to a collar 8 which surrounds shank 2 and isslidable thereon.

Collar 8 and rod 6 are moved up and down on shank 2 by a lever arm II having an angled flat portion I2 pivoted to head I at I3 and pivotally connected at its extremity I5 to a link I4, the other end of which is pivoted at II to an ear I6 on collar 8. As shown more clearly in Fig, 3, lever arm 'II is provided with'a handle I8, preferably of wood, held in position on lever arm II by a steel ferrule I 9. 'I'his portion of lever arm II, carrying the handle I8 and steel ferrule I9, is bent to project to. the right of and at a right angle to lever arm II.

Referring to Figs. -1, 3, and 4, and particularly to Fig. 4, there is shown an automatic locking device for holding the parts in the position shown in Fig. 1, i. e., with the rod 6 in the raised position there shown.

The locking device comprises a pin 2|! having a rounded head 2! reciproeally mounted in a bore CFI 23 in head I. vA spring 24 housed in bore 23 between head 2I and a shoulder 25 holds pin 20 normally in an extended position with its rounded head 2I protruding beyond the surface of head I of the tool. Pin and its rounded head 2| may be adjusted in the bore 23 by a nut 26 threaded on pin 20. g

Upon the up stroke of collar 8, pin 2li enters a recess in a latch 21 secured to collar 8 by screws 28. The upper extremity of latch 21 is provided with a beveled surface 29' to contact head 2I and force it into the bore 23 until the recess 30 is opposite head 2l, at which time the spring 24 will force head 2l into recess 30 and hold collar B and rod 6 in raised position until lever arm Il is operated to release the locking device.

'I'he tool is operated in the following manner:

In Fig. 5 is shown a box 3| bound with wires 32 provided with

fasteners

33 and 35 on their respective ends. Fastener 33 on top section 34A is wider than fastener on front section 36', as shown in Fig. 10, so that fastener 33 may be readily placed over fastener 35. v

In Fig. 5 the top section 34 is in position for closing by the tool ofy this invention. In this position, the fastener 35 on the front section extends up to or through the fastener 33 on the top section.

Referring to Fig. 6, hook 4 of shank 2 is hooked under fastener 35 of front section 36. The handle end of lever arm Il yis then moved upwardly to the position shown in Fig. '7. This movement of arm II, acting through link I4, forces collar 8 and rod 6 downward. Downward movement of rod 6- oauses notch 1 at the lower end of rod 6 to engage fastener 33 of top section 34 and force top section 34 down into contact with side section 36 and at the same time bend fastener 33 down tightly over the edge of top section 34, as shown in Fig. '7. From this position the tool is swung outwardly from the box and downwardly to the position shown in Fig. 8, thus hooking fastener 35 around the bight of fastener 33 with enough tension to hold top section 34 in closed position and to secure interengagement of

fasteners

33 and 35.

The tool is readily disengage by raising handle I8 slightly upward toward the closure so that hook 4 disengages fastener 35.

Fasteners

33 and 35 may be positioned against the face of front section 36 by using the steel ferrule I9 as a hammer, as shown in Fig. 9, or by simply pushing the fasteners toward the face of the front section with a thumb or finger.

The term loop-fastener as used in the claims is intended' to include the U-shaped type of fastener shown at 33 and 35 of the drawings.
