8 Claims.

This invention relates to a device adapted for use in the emptying of bags of sugar, flour or other commodities without permitting refuse which has collected on the surface of the bag to be separated therefrom and carried along with the contents.

It is an object of the invention to provide an emptying device of the above-described character of simple construction and relatively inexpensive, and which may be readily cleaned, secured to the bag, and removed therefrom after the bag has been emptied.

In the accompanying drawings illustrating a preferred form of the invention:

Figure 1 is a perspective view of the bagemptying device, a portion being indicated as having been broken away, and the bag-attaching ring being disassembled from the casing.

Fig. 2 is a perspective view of a bag of merchandise ready to be emptied.

Fig. 3 is a perspective view of the bag-empty ing device after it has been set over a bag, the bag opened, and the upper marginal portion of the bag secured to the neck of the emptying device by means of the resilient clamping ring.

Fig. 4 is a large-scale detail view in crosssection through one side of the upper end of the emptying device and the adjacent portion of the bag.

Fig. 5 is a view, partly in side elevation and partly in cross-section, illustrating the positions of the bag and the emptying device after the bag has been emptied and inverted to entirely dislodge the contents.

Fig. 6 is a large-scale cross-sectional view of the upper end of the emptying device and the attached portion of the bag in the positions assumed at the end of an emptying operation.

In the form of the invention which has been selected for purposes of illustration the emptying device comprises a cylindrical casing 20, preferably of metal or other appropriate relatively rigid material, which should be open at the top and which may also be open at the bottom. This casing should be of a size such that it may be readily set over a bag 21 (Fig. 2) of merchandise to be emptied, and the attachment of the emptying device to the marginal portion of the bag may be facilitated by reducing its diameter at its upper open end as at 22 and by providing the reduced portion with an upstanding neck portion 23, which should preferably be beaded at its margin as indicated at 24.

One appropriate means of securing the marginal portion of the bag to the neck 23, as indicated in Fig. 1, may comprise a ring 25 of resilient metal having portions thereof bent to form handles 26, and these handle portions may be of such form as to break the continuity of the ring 25 and provide for expansion and. contraction, thus adapting the ring to be snapped over the beaded neck 23 of, the emptying device.

The emptying device may be provided with suitable means, such, for example, as the handles 27, whereby it may be grasped and firmly held when used to empty a bag of merchandise. The most appropriate position for these handles, as indicated in Figs. 1 and 3 of the drawings, is

at a point between the center and bottom of the emptying device. In other Words, the handles should be nearer the bottom of the device than the top.

When using the device to empty a bag, the casing is first dusted or wiped free of any loose dirt or refuse and is then placed over the bag, the mouth of which is opened and the marginal portions turned over the neck 23, and the resilient ring snapped in place over the neck as indicated in Fig. 3. The bag and emptying device may then be inverted over the mouth 28 of a bin or container as clearly indicated in Fig. 5, and as the bag is emptied it may be turned inside out and subjected to a thorough shaking in order to entirely separate every particle of the contents.

As will be clear from an inspection of Fig. 5, any dirt or refuse which may have collected upon the outer surface of the bag while in transit or at any time up to its attachment with the emptying device will, during the emptying operation, be trapped within the emptying device and within the inverted bag itself, and none of this refuse will be permitted to fall into the bin or other container.

After the bag has been emptied the emptying device and the bag may be removed from the mouth of the bin and the bag separated from the emptying device by merely grasping the handles 26 of the ring 25 and pulling it free from the neck 23 of the casing. The casing may then be again brushed or wiped free of refuse, ready to be placed over another bag to be emptied.

In its broadest form the emptying device comprises merely a cover or casing adapted to enclose the bag and having an upper open end to which the marginal portion of the bag, when opened, may be secured, so that the external portion of the bag will be contained in the casing when inverted to empty the bag, at which time its iio

all refuse will be held by the casing and the bag which closes the mouth of the casing.

The invention is not intended to be limited to the preferred form herein selected for purposes of illustration but should be regarded as covering modifications and variations thereof within the scope of the appended claims.

What is claimed is:-

1. A bag-emptying device comprising a mobile, imperforate open top casing of a size appropriate to receive the bag to be emptied, and readily attachable and detachable means whereby the upper marginal portion of the bag may be securely fastened to the open end of the casing, whereby the bag and casing may be inverted and the bag emptied without danger of causing the bag to be accidentally detached from the casing, the casing serving as a means of catching and holding any refuse which may be separated from the outer surface of the bag.

2. A bag-emptying device, as defined by claim 1, of which the casing is open at the bottom as well as at the top, thereby facilitating the cleaning of the casing of any accumulated refuse prior to using it in opening of a bag.

3. A bag-emptying device, as defined by claim 1, of which the casing has a handle by which it may be grasped and held while emptying a bag.

4. A bag-emptying device, as. defined by claim 1, of which the casing has. a pair of oppositelydisposed handles located nearer the bottom than the top by which it may be grasped and held while emptying a bag.

5. A bag-emptying device, as defined by claim 1, of which the casing is a rigid structure and of which the bag-securing means is a ring between which and the open top of the casing the marginal portion of the bag may be clamped.

6. A bag-emptying device, as defined by claim 1, of which the casing is a rigid structure having a beaded neck about the opening at the top and of which the bag-securing means comprises a resilient ring of a diameter such as to be snapped over the beaded neck with the marginal portion of the bag clamped between the neck and the ring.

'7. A bag-emptying device, as defined by claim 1, of which the casing is a rigid structure having a beaded neck about the opening at the top and of which the bag-securing means is a ring of resilient metal of which portions are bent laterally to form a pair of handles and break its continuity whereby it may be expansible, the diameters of the ring and the neck of the casing being such that the marginal portion of a bag may be clamped between them.

8. A bag-emptying device comprising a mobile, imperforate cylindrical, metal casing open at the top and open at the bottom, a beaded neck surrounding the opening at the top of a diameter less than that of the body of the casing, a resilient clamping ring having portions bent to form handles and intervening portions in the forms of circular arcs of a diameter such as tobe snapped over the beaded neck of the casing, and handles near the bottom of the casing by which it may be grasped and held.
