OHIO, Av CORPORATION OF OIIIO 'BAG notnme AND rILLiiae DEVICE Application filed Jul is,

This invention relates to means for holding bags while they are being.filled, andfor facilitatingthe filling of the bags; and its general objects are to provide a relatively simple and inexpensive means of the afore-' said nature that is especiallyconvenient of use, that is rugged, substantial'and durable, that greatly expedites the bag filling operation, and that is non-adjustable yet is equal- 1y suitable for use with bags of various sizes throughout a considerable range.

According to the present disclosure, the invention is incorporated in a hand truck, although it is to be understood as not limited to such an association. Essentially, the invention consists of a supporting structure, a funnel orflhopper carriedthereby, and a device for sustaining the bag, preferably at two points locatedon opposite sides of the 0 discharge spout of the funnel or hopper, with the, mouth of the bag drawn about the spout, said spout serving to maintain thebag open during the filling operation.

A further object ofthe invention is to provide supporting meansto which the bag may be very quickly andeasily applied by simply engaging the material of the bag over hooks or the like, and from which the bag may be disengaged with even greater ease by simply. releasing the supporting means,

allowing it to collapse or drop and thereby disengage itself from the bag, or assume such a position, that the bag may be lifted away from the device without interference.

The foregoing objects, with other and more limited ones hereinafter appearing, are obtained in the embodiment of the invention illustrated in the accompanying drawings wherein Fig. 1 is a side elevation, and Fig. 2

a front elevation, of my improved bag holding and filling means; Fig.3 is a section on the line 33 of Fig. 1; Fig. 4: is an enlarged sectional detail of the bag sustain-ing device, and Fig. 5 is a perspective view thereof. As previously stated, the invention is shown as incorporated in a hand truck and from the standpoint of utility this makes a very practical and convenient combination.

For the present purpose, however, the hand be regarded broadly as a supthe mouth of 1928. Serial No. 292,926.

porting frame or structure, and obviously such frame orstructure could be applied to, or mounted upon, a platform or other type of scale so that a given quantity of the commodity that is to be placed Within the bag could be deposited therein, as would be indicated by the scale, in the initial filling of onic, AssIGNoR ro {run enABLiin the bag. Such an applicationof the invention is so apparent that specific illustration thereof is deemed unnecessary.

The supporting frameor structure is designated, generally, by the reference numeral 1, and supported by, and forwardly of, its upper portion, as by means of brackets 2 and 3, is a'hopper 4 having a discharge spout 5 about which the mouth of a bag 6 is adapted to be drawn. In applying the bag to the hopper, the material of the bag is gathered to gether on opposite sides of thespout 5 and engaged over relatively sharp and thin hooks '4" that are suitably connected, by rivets 7, to the forward ends of arms 8, the rear ends of said arms being shown as turned inwardly and riveted or otherwise secured to a crossbar 9. whose endsare formed with trunnions 9 jonrnaled in brackets 10 that are. suitably connected to and project slightly forwardly of the side members of the sup-- porting. frame or structure 1. The cross bar 9 and arms 8, with their hooks 7 make up Applied to the rear side of the cross bar 9 at about its longitudinal center is a handle 11, and extending from one side of this handle is a headed stud 11' that is engaged through an L-slot 12, in a latch plate 12, said plate being pivoted at 13 to a bracket 14 that is fastened toa transverse member 15 of the supporting frame or structure 1. The yoke, comprising the parts 8 and 9, isheld in bag sustaining position by means of the latch plate 12, this end being effected by the engagement of the stud 11 within the offset lower end of the slot 12 After the desired amount of material has been placed within the bag, the latch plate 12 is swung forwardly at its upper end to remove the stud 11 from the oifset lower end of the slot whereupon the stud is free'to rise within the slot, permitting the handle 11 to beelevated so so a yoke that constitutes the bag holding means.

V eI-Iavlng that the arms 8 may drop and allow the bag to fall away from the spout 5 of the funnel or hopper 4;. When the bag holding or sustaining-means thus collapses, the hooks 7 either withdraw from the material of the bag, or assume such aposition that the bag may be lifted there'from'without interference. Preparatory to applying another bag to the holdlng means, the handle 11 is swung clownwardly and is automatically locked in its de pressed position by the latchplate 12 gravitating to effective position wherein the stud 11 occupies the offset lower end of said slot. "With the handle held depressed, the arms 8 are, of course, retained in bag holding posi tion. 7

hus described my, invention, what Irclaim is:

1. In a device of the character described, the combination ofja supporting structure, a hopper sustained thereby, said hopper having a discharge spout, a yoke pivoted to the supporting structure and incorporating arms that are disposed on opposite sidesof the spout when the yoke is in bag sustaining position, a handle on the yoke for swinging it to said position, a latch carried by the supporting structure for cooperation with saic handle to maintain the yoke in bag sustaining position, and means on said arms wherewith a bag is adapted to be engaged at restricted points on opposite sides of the spout of the hopper for holding the bag with its mouth spread open by the spout.

2. In a bag holding device of the characterdescribed, the combination of a supporting frame, across bar pivotally connected at its ends to said frame,arms extending from one side of said cross bar and spaced apart longitudinally of the bar, a handle extending from the opposite side of said cross bar, means releasably holding the parts in a position with said arms substantially horizontal, and bag attaching means carried by the free ends ofsaid arms. I

3. In a bag holding device of the character described, the combination of a support ing frame, a cross bar pivotally connected at its ends to said frame, arms extending from one side of said cross apart longitudinally of the bar, a handle extending from the opposite side of said cross bar, a latch movably connected to the supporting structure for cooperation with a part on said handle for holding the parts in a po sition with the aforesaid arms substantially horizontal, and bag attaching means carried by the free ends of said arms.

4. In a bag holding device of the character described, the combination of a supporting frame, a cross barpivotally connected at its ends to said frame, arms extending from one side of said cross bar and spaced apart longitudinally of the bar, a handle extending from the opposite side of said, cross bar, a latch .Wardly from the cross said keeper, the latch bar and spaced comprising tWo cooperating elements that are carried, respectively, by the handle and the supporting structure for holding the parts in a position with the aforesaid arms substantially horizontal, and bag attaching means carried by the free ends ofsaid arms.

5. In a bag holding device of the charaoter described, the combination of a supporti-ng frame, laterally spaced brackets carried by said frame, a crossbar trunnioned at its ends in said brackets, arms extending'forbar and spaced apart longitudinally thereof, bag attaching means carried by the free ends of said arms, a han-. dle extending from the side of the cross bar opposite that from which said arms project,

a latch plate pivotally connected to the sup porting frame and disposed adjacent said handle, said latch plate having aslot provided with an ofiset portion, and a stud extending from said handle through said slot and 'arran 'ed to be engaged within the offsetportion of the slot when the aforesaid arms are in bag sustaining position. 7

6. In a bag holding device of the character described, the combination of a supportingfr me, laterally spaced brackets carried by said frame, a cross bar trunnioned at its ends in said brackets, arms extending forwardly from the cross bar and spaced apart longitudinally thereof, relatively thin and sharp bag attaching hooks carried by the free ends: of said arms, a handle extending from the side of the cross bar opposite that from which said arms project, a latch plate having a keeper, and a member for engagement with plate and member being carried, respectively, by the handle and the supporting frame, and cooperating to hold the parts against movement whenthe aforesaid arms are in bag sustaining posi tion.
