4 Claims.

This invention relates to an improved packing means.

One of the objects of the invention is to provide.

an improved packing means.

Another object of the invention is to provide means for supporting the side walls of packing cases during packing thereof.

Other objects of the invention will be apparent from the description and claims which follow.

The device of the present invention comprises a supporting member provided with adjustable clamping means and is especially adapted for use with packing cases such as, for example, the conventional poultry packing cases formed of plywood side and end walls, the end walls being recessed within end supporting stays. In use, the supporting member is secured adjacent the free edge of one side wall of the packing case by clamps anchored against opposite end stays.

Reference is had to the drawing in which like characters of reference are used to designate similar parts.

Figure 1 is a perspective view showing the device of the present invention applied to a packing case.

Figure 2 is a plan view of the clamping means secured at one end of. the device.

Figure 3 is an end view of Figure 2.

Figure 4 is a plan view showing the adjustable clamping means.

Figure 5 is an end View of Figure 4.

The packing case shown in Figure 1 comprises bottom I, side walls 2, and end walls 3, the end walls 3 being recessed within end stays 4, 5 and 6. In practice, the packing case is provided with an inner liner 1 and it will be seen that the device of the present invention, in addition to supporting the side walls, serves also to hold in place the liner 1 during packing of the case.

The device comprises angle iron supporting member 8 provided with ledge 9 for supporting the side wall of the packing case, and ledge IQ for rigidly supporting clamp l I and slidably supporting clamp l2. Ledges 9 and I0 form, respectively, side and top members. As shown in Figures 2 and 3, clamp H is welded or otherwise rigidly secured to ledge I0, as at l3, and provides arm l4 extended in spaced relation with ledge 9. Arm I4 is of suitable depth to assure a good hold and is provided with outwardly flared free end IE to facilitate application of the clamp against end stay 6.

As shown in the drawing, the supporting member 8 is substantially L-shaped in cross-section and clamp 12 is slidably mounted upon the supporting member although it will be understood that clamp l2 may be rigidly secured similarly to clamp II should it be desired to employ the device only on a standard size packing case.

However, it will be seen that even then, the employment of the slidable clamp will greatly facilitate application of the device to the packing case. Clamp l2 comprises U-shaped claw l6, slidable over ledge l0 and provided with arm I! extended in spaced relation with ledge 9 similarly to arm M. Also, similar to arm l4, arm I! is provided with outwardly flared free end I8 to facilitate its application to opposite end stay l9. Lug 20 is welded or otherwise rigidly secured to claw I6 adjacent ledge 9 to prevent lateral displacement of clamp I2.

In use, the side flaps of liner 1 are folded over and against the outer walls of sides 2 and thereafter the side flaps of liner 1 are secured in place and the sides 2 rigidly supported for packing of the case by a supporting member 8 secured adjacent the outer free edge of each of the sides 2 by clamps II and I2 anchored against opposite end stays 6 and I9.

I claim:

1. A frame for supporting a wall of a packing case during packing thereof, comprising a substantially rigid supporting member substantially L-shaped in cross-section having a ledge for fitting along the side of the packing case, a stationary bracket rigidly secured to the top of said supporting member, and a slidable bracket slidably secured to the top of said member, each of said brackets having an arm extending in spaced parallel relationship to said ledge to provide space between the ledge and the arms for the side of the case.

2. A frame for supporting a wall of a packing case during packing thereof, comprising a rigid supporting bar having a ledge to fit along the side of the case and a flat top member extending at a right angle to said ledge, a stationary bracket rigidly secured to said top member, and a slidable bracket slidably secured to said top member, each of said brackets having an arm in spaced parallel relationship to said ledge to provide space between the ledge and the arms for the side of the case.

3. A frame for supporting a wall of a packing case during packing thereof, comprising a rigid supporting bar having top and side members forming substantially a right angle, a stationary bracket rigidly secured to one end of said supporting bar, and a slidable bracket having a claw for fitting over said top member, each of said brackets having an arm in spaced parallel relationship to said side member of the supporting bar to provide space between the side member and the arms for the side of the case.

4. A frame for supporting a wall of a packing case during packing thereof, comprising a rigid angle member having top and side members for supporting the side of the case, a stationary bracket rigidly secured to the top member at one end of the angle member and a slidable bracket having a claw to fit over the edge of the top member and a lug on the slidable bracket to hold the claw in engagement therewith, each of said brackets having an arm in spaced parallel relationship to said side member to provide space between the side member and the arms for the side of the case.
