. 1o claims. (ci. 24a- 100) My invention relates to devicesv for holding bags while lling these. i

The invention aims, for its objects,l to provide a bag holder that vis inexpensive to build, one

which issimple in operation, one which may be rapidly disengaged from the bag when the latter has been iilIed, one which operates with ease and rapidity to engage a bag in preparation for iilling the latter; and a bag holder which holds a bag with the mouth thereof positively expanded during a filling operation.

The manner of accomplishing the foregoing objects. as well as further objects and advantages, will Ibe made manifest in the following description taken in connection with the accompanying drawing, in which:

Fig. l is a perspective View of a preferred em- Ibodiment of the bag holder of my invention mounted upon astationary support.

Fig. 2 is a horizontal sectional view taken on 20 the line 2 2 of Fig. 1.

Fig. 3 is an enlarged vertical sectional view taken on the line 3-3 of Fig. 1.

Referring specifically to the drawing, I have shown my invention therein as embodied in ai25 bag holder I0 which is mounted upon arms II provided on a xed pedestal I2. This bag holder is frequently mounted on a bagging and weighing device. It is here shown as having a station- 4ary mounting to` simplify the 'disclosure asthe 30 There are preferably two auxiliary sections I'I in 40 each of the two groups of these aforesaid and the sections of each group are joined together and one edge of one of said sections of each of `said groups is connected to a corresponding edge of the base section I6 by internalV hinges 2| the I 45 axes of which are disposed within the annulus 'I5 and preferably substantially paralle1 with the axis of this annulus. The hinges 2| are also applied so as not to permit [further outW-ard swinging of one bf the sections IB or I1 relative to150 each other beyond that swinging movement neoessary to expand these sections to produce the annulus I5. The opposite edges of each of the groups of sections I1 from those edges thereof which are connected to the base section I5, are 55 The base section I6 is secured as` 35 connectedtogetherby an external hinge 22, pin 23 of which is bent rearwardly and into an eye to form an operating handle 24.

` Extending outwardly from the sections I5 are bag holding means such as pins 25.

Operation,

The bag holder I0 `of my invention is adapted to be manually operated, the rst step being to collapse the annulus I5 by pushing inwardly on the handle 24, this extreme collapsed position being shown by dotted lines 30 in Fig. 2. The mouth of the empty bag is now pulled over the bead and' then lifted above the level of the bottom of the annulus I5 while the handle 2li is pulled outwardly to expandthe annulus when in the mouth of the bag as shown in Figs. l and 3. Tov accomplish this the sections II successively pass from the position 30 to the positions shown by vbroken lines 3l and that shown by the broken lines 32 (see Fig. 2). In order to complete the expansion ofthe annulus I5 from the position shown by broken lines 32 to the position shown in full lines in Fig. 2, the base section I5 must be sprung slightly as indicated by broken lines 33 in Fig. 2. The reason for assembling the bag holder Ill in this manner is so that when the annulus I5 is completely expanded it will tend to remain in an expanded conditionV and will eifectively resist forces tending to collapse this while lthe bag is being filled.

When the annulus I5 is expanded in order to support the mouth of the bagvB for filling the -`lattery the pins extend through or into the material'of the bag B and cooperate with the bead 20 to positively prevent the bag coming olf the bag holder I0 while the annulus I5 is ex'- panded After a bag B has been applied to the bag holder Ill as above described, material is delivered through the annulus I5 into this bag. When the desired amount of material has thus been delivered into the bag, the handle 24 is pushed inwardly to fully collapse the annulus I5 as indicated by broken lines 3l] of Fig. 2. This withdraws the pins 25 from the bag and allows the rear portion of the mouth of the bag to fall away from over the bead 20 so that the filled bag may 4readily be shifted away from under the bag collapsed as indicated :by the broken lines 30 in Figs. 1 and 2.

I claim:

1. A bag holder comprising: an annulus adaptl ed to extend into and be ex-panded in the mouth of a bag, said annulus being formed of at least three sections hinged together at their respective contiguous :ends on axes parallel with the axis of the annulus, certain of said sections lbeing collapsible inwardly by pivoting said sections relative to each other about said hinge axis to disengage said holder from a bag.

2. A bagholder comprising: an annulus adapted to extend into and be expanded in the mouth of a bag; bag engaging means .on the outer surface of said annulus for retaining said 4bag on said annulus when the latter is expanded in Said mouth, said annulus being l'formed 'o'i at least be expanded inthe mouth `of a bag, :one of said 4 sections being larger than :the other; .and .mounting means connected `to said Llarger section ,in-order to support said annulus, said .other sections Ibeing adapted to-collapse .the plane of said annulus by said sections pivoting relative .to leach other about said .hinge axes and .extend into the space within said larger :section :torelease .a ybag from around said annulus.
