Application filed May 25, 1914. Serial No. 840,916.

T czZZ whom t may concern Be it known that I, IIe-"Gir Il". FnLLows, a citizen of the United States, and a resident of Los Angeles, county ot Iios lrngeles` and.

5 State of California, have invented certain new and useful Improvements in Bag- Holders, of which the following is a full, clear. and exact description. V

The invention relates to bag-holders and Vo seeks to providesiniple and eiiective means whereby bags may be securely but detachablyT held upon a filling spoiit or the like and which obi'iates the necessity of employing thereupon spikes or catches, which are i5 apt to tear the bags and injure the hands of the persons placing the bags in position.

The invention consists in the features of improvement hereinafter set forth, illustrated in the preferred Jforni in the accomvpanying drawing, and more particularly employed for delivering grain from a threshing machine. Fig. 2 is a View in elevation of the parts shown in lig. 1. vIn Figs. 1 and 2, the grippers for holding the bag in place are shown in released position,

310' Fig. 3 is a view in vertical section of the parts shown in Figs. 1 and 2,` with the grippers in` operative position. y

.The improved bag-holder is mounted upon a Suitable head which, in the preferred forni shown, is rectangular in outlinean'dA comprises opposite parallel side walls l0 and downwardly and outwardly inclined end walls 11. formed directlyupon thel discharge end of 404 the filling spout 12. In the 'forni shown,

the spout is provided with a flaringfend portion 13 which extends within and is riveted, or otherwise suitably secured, to the upper portion of the head. U .t

The gi'ippers for holding the bag in position upon the head are mounted upon pairs of arms 14 which, as shown, are arranged 'on opposite sides of the inclined end walls 11 of the head and which project outwardly and downwardly from the upper portion of the head. In the construction shown, these arms are formed by the downwardly bent end portions of a pair of strapsl which are secured to the upper portions o' the opposite.

side walls 'l0 of the head.

i which the wedging,

If desired, the head may be 1-i wedging, cani-shaped gripper is pivotallyinounted upon the end oi' each arm and projects inwardly toward the adiacent inclined end wall ll. ot the head andcopcrates therewith to hold the bag in place. is shown, the arnis are proa'ided with inwardly projecting horizontal. stads 16 on Y ini-shaped grippers are mounted. Each cam gripper comprises an inwardly projecting arm 17, an upwardly projecting arm 18 and an arc or cani-shaped shoe 19 upon the inner end oi the arno li". The angle between the arins 17 and 18 is preferably slightly less than a right angle and the grippers are so disposed that they tend to swing by gravity to lbring the shoes 1 9 into engagement with the opposite inclined end walls 11 ofthe head. Tliei'shoes 19 are provided with curved or arc-shaped working or gripping faces which are struck from centers located above the centers oi' the pivot studs 16, so that there is a. wedging action between the gripping shoes and the end walls of the head.

The grippers'are shifted to release the bag by means of a pair of bails 2O and 21, the

arms or' which are piv'otally mounted atl their lower ends in the supporting arnis 14 and extend upwardly between the arms 18 and the ends of the shoes 19 of the wedging gripiiers` The bail 2O is considerably longer than the bail Q1 and serves as a handle for shitting the hails. The'bail 21 is provided at one end with a depending crank portion Q2 which is connected tctlie bail 20, prei'- erably by a chain In the normal position of the parts, the wedging grippers rest by gravity in engageinentwitli the opposite end 'faces of the head ll. The spaces between the ends of the shoes 19 and 'the arms 18 through which the hails 20 and 21 extend, are considerably wider tlianthe arms of the bails, so that the wedging grippers are tree to -swing independently 'to a limited extent upon the pivot studs 16. For this reason, the free edges or upper end ot'the bag 24 may be readily slipped over the ,head and between the end walls and the cam or arc-shaped 'working faces of the gripping shoes 19.Y v then drop by gravity and engage the bag, as shown in Fig. 3. Any downward pull tending to disengage the bag will tend-to'tiirn the grippers downwardly about their pivots 16 and so force or wei'lge the gripping faces The la tter of the shoes between the pivots 16 -and intli'ned end faces of the walls l1 to more securely grip the upper' portion of the bag. In this way, any pull on the bag tending to .disengage it serves to more securely hold it in place. But the gripping wedges may readily swing upwardly to release the bag and they can all be shifted simultaneously to released ,position by means of the connected bails 20 and 21. as shown in Fig. Q. In the extreme upward movement of the grippers shown in Fig. 2, the arms 17 thereof engage the lower outturned ends of the arms of the bail so that the latter serve as stops to limit the upward or releasing morementvof the grippers. The arrangement ofthe bail arms between the arms 1S and shoes 19 of the grippers also serve to maintain the grippers in proper position, while permitting a limited independent movement thereof.

It is obvious that changes may be made in the details set forth without departure from the essentials of the invention as defined in the claims.

I claim as my invention l. A'bag holder-comprising a. head, a series of independently movable, automatically wedging grippers mounted on said head, and means loosely engaging said wedging grip pers for releasing the same. i v '2. A bag holder comprising a head, a se'- riesV of independently movable, automatically wedging gripper-s pivotally mounted onv said head, and a series of connected devicesY the bag thereon, and a series lof connected pivot arms loosely engaging said grippers for releasing the same, substantially-as de` scribed.

el. A bag-holder comprising a head having projecting arms, a series of inwardly pro- ,jecting wedging grippers pivoted on said armsy and coperating with said head to hold the bag thereon, and means loosely engaging said gripper-s forreleasing the same, said 'grippers having smooth arc-shaped working faces and said head having outwardly and downwardly inclined faces opposed to the smooth curved faces of said grippers,4

substantially as described.

5. A bag holder comprisinga head. a series of independently movable, automatically wedging grippers mounted on said head. and devices having a. lost motion engagement with said Wedging grippers` for releasing the same, said' releasing devices being arranged to limit the independent movement of said wedging grippers in opposite directions.

6. -A bag-holder comprising a head having wedging grippers pivoted on said proj ccting' parts, extending inwardly toward the inclined ends of said head, and havingr arcf shaped working faces coperating with said inclined ends, and means for simultaneously releasing said grippers` substantially as described,
