arrla ti a fi ed Ji y whereby the funnel may be suspended from a weighing device, thereby allowing a predetermined quantity of material to be placed in the sack, and obviating the necessity of weighing the sacks after they have been I filled as is the practice at the present time.

A further object is to provide the opposite sides of the funnel adjacent the lower end thereof with rock shafts having their ends provided with outwardly and upwardly 1nclined prongs for piercing opposite S1Cl9S f a sack and spring means for normally main. taining the rock shaft in a position where its prongs will incline upwardly and outwardly. The rock shafts are provided with upwardly and outwardly inclined arms which are held against downward movement under the weight of a sack suspended on the prongs by means of pivoted hooks cooperating wlth the arms. Also to provide a rock shaft having a handle member and arms cooperating with the pivoted hook whereby the rock shaft arms maybe simultaneously released for allowing disengagement of the sack from the prongs under the weight of the material within the sack.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed wthout departing from the spirit of the invention.

In the drawing Figure 1 is a side elevation of the funnel.

Figure 2 is an enlarged bottom plan view of the funnel.

Figure 3 is a detail sectional view taken on line 33 of Figure 1. 7

Referring to the drawing, the numeral 1 designates a tapered funnel,'the lower end of which is of sufficient width to be received within the upper end 2 of a ba -or sack. EX- tending upwardly from the funnel 1 is a ea-5.- s ie 'k asleea fl vmeans of ch th funnel may be ,suppm't d from a support, o f om weighing scales, whereby the amonnt ,of material discharged into the sack 2 through the funnel 1 may be accurately determined, consequently sacks of uniform weight are filled. RofclG-ibly mounted in bearings 4 at opposite sides of the discharge opening .5 are rock shafts 6. The ends of the shaft .6 areprovided with upwardly and outwardly inclined prongs 7 adapted to pierce opposite sides of the sack 2 and support the opened end of the sack .over ,the lower end ,of the funnel, whereby natefiill deposited in the funnel will be deposited in the sack. Surrounding the rock shafts 6 are coiled springs 8, one of the ends of which are anchored at 9 to the sides of the funnel and the other ends of the springs are anchored at 10 to upwardly and outwardly extending arms 11 of the rock shafts. It will be seen thatthe springs 8 will normally force the arms 11 upwardly, however the springs 8 are not of suflicient tension to support a sack full of material, therefore it will be seen that when a sack has been filled, and the arms .11 released by tripping mechanism hereinafter set forth, the weight of the sack on the prongs 7 will cause the rock shaft 6 to rotate against the action of the coiled springs 8, thereby automatically disengaging the sack from the funnel after a filling operation.

Pivotally mounted at 12 in recesses 13 at the opposite sides of the funnel 1 are outwardly extending latching members 14, which latching members hook over the outer ends 15 of the arms 11, and hold said arms adjacent the sides of the funnel with the piercing members 7 inclining upwardly and outwardly, therefore it will be seen that the sack 2 will be positively connected to the funnel during the sack filling operation, and said sack will be immediately released upon an upward movement of the latching members 14, however when the arms 11 are moved upwardly after a sack releasing operation, the ends 15 of the arms 11 engage the in clined surfaces 16 of the latches and force the same upwardly until the ends 15 of the arms 11 are received in the recesses 17 of the latches. Rockably mounted in bearings 18 at one side of the funnel is a rock shaft 19, the ends of which rock shaft are provided with angularly disposed arms 20 at opposite sides of the funnel, and which arms have link connections 21 with the latching members 14. \Vhen the operator desires to release the sack 2, he grasps the handle member 22 of the rock shaft 19 and forces the same downwardly, which action will move the arms carried by the shaft 19 upwardly, and which arms will impart upward pulls on the latching members 2%, through the medium of the link connections 21, thereby releasing the arms 11 and allowing the sack and the weight of the material therein to rock the rock shafts 6 against the action of the coiled springs 8.

From the above it wi]l be seen that a sack filling funnel is provided which is simple in construction, positive in its operation and one wherein the parts are reduced to a minimum. thereby allowing the device to be cheaply constructed and sold.

The invention having been set forth what is claimed as new and useful is A sack holding funnel comprising a body member, one end of which is adapted to be received within an open end of a sack, rockable members at opposite sides of the body member, sack piercing arms carried by the ends of the rockable member, upwardly and outwardly extending arms carried by the rockable members, springs surrounding the rockable members and cooperating with the body member and said upwardly and outwardly extending arms for normally forcing said arms inwardly, pivoted latches at opposite sides of the body member and cooperating. with the up *ardly and out ardly extending arms, a rock shaft carried by one side of the body member, arms carried by the ends of the rock shaft and overlying the adjacent sides of the body member, link connections between said last named arms and the latching members, and a handle member carried by said rock shaft.

In testimony whereof we have signed our names to this specification.
