Patented Dec. 7, 1948 UNITED `STATES PATENT OFFICE l 1 l 2,455,72e l SACK IHIOLDER-` Lawrence Byers, Homeworth, `Ohio `Application January 16, 1947, `Serial No. 722,3?!1

tachably hold various sizes of sacks in open position for filling, and on which the sacksmay be quickly and easily mounted.

Various prior sack holding constructions have `been devised for holding sacks in open position while filling them with feed andgrain and "other produce, or with comminuted materials such as cement, fertilizer, ete.`

However, these prior constructions have had Certain of them have been too complicated and expensive to make, while others have been too heavy or cumbersome for unskilled persons to use, andstill others have not been easily adjustablefor different sizes and lengths of sacks, or have required too much tim for attaching and vdetaching the sacks. i

Accordingly, itis a general object of the `present invention to provide a new and improved sack holder which overcomes the dsadvantagesof prior constructions.

More specically, it is an object of the present invention to provide an improved sack holder which is readily adapted for holding sacks of various sizes in girth.

Another object is to provide an improved sack holder which is quickly adjustable to accommodate sacks of various lengths.

Another object is to provide an improved sack holder which has novel hopper means for quick attachment to the mouth of a bag.

, Alfurther object is to provide an improved sack holder which is portable.

Another object is to provide an improved sack holder having a removable hopper adapting the holder `to be used as a hand truck.

` A still further object is to provide a novel and improved sack holder which is simple and inexpensive in construction, light in weight, and easy the nature of which is set forth in the following general statement, and a preferred embodiment 4 claims. (o1. 24a- 97) of which is set forth in the folowing description T,

and illustratedin "the accompanying drawings,

, l 2 l and which is particularly and distinctly pointed out and set forth in the appended claims forming parthereof. l f

Ingeneral terms, the improved sack holder `comprising'the present invention may bestated as including a hopper which is slidable vertically on a `normally upright standard and which may be quickly removed from the standard, there being a spring-held friction clamp on the hopper for normally holding the hopper in `adjusted position, and prongs at the base of the hopper for engaging the mouth of a bag in open position, a

`gravity latchbeing provided on the hopper for gripping the fabric of the bag around one of the prongs, and wheels at the base of the standard for moving the sack holder about.

Fig. 3 is afragmentary sectional View aston line 3 3, Fig. 2;

Fig. 4t` is a. transverse sectional view as on line `Fig.'5\is a fragmentary rear elevational view of 'the hopper detached from the standard; and

lFig. 6 is a fragmentary sideelevational view `similar to` Fig. 2 showing an extension attache tothe hopper for filling a paper sack. l

Similar numerals refer to similar parts throughout the several views of the drawing.

` `The improved sack `holder `preferably includes -a `base `which may be made up of side angles 'l and a reartransverse angle 8 extending between and secured `to the side angles,` as by welding. As shown transverse plates 9 may extend across the tops-of the side angles l and are preferably secured thereto to form a platform on top of the base. If desired suitable bracket plates l0 may be secured to `and extended rearwardly from the side angles 1 for supporting a transverse shaft "ll, on which a pair of wheels l2 is mounted for `rollably supporting the bag holder when it is tilted rearwardly. s

At the central portion of the transverse angle 8 an upright standard I3 is mounted, `and the standard may consist of two angles lll secured to each otherin side-by-side abutting relation, and

'secured at their bottom ends to the transverse angle 8, as by welding. As shown in Figs. 1 and 2 ,l angle braces l5 are secured at their lower ends -to` intermediate portions of the angles 1, and are secured at their upper ends to the rearwardly extending anges of the upright angles I4. Thus, the standard is T-shaped in cross section, as best shown in Fig. 4, and the laterally extending legs Ma provide a continuous track on which to slidably and removably mount a hopper. Preferably, a handle I5a is attached by welding to the abutting legs of the angles I4 at or near the tops thereof for facilitating tilting the standard rearwardly vto rollably support it ony thewh'eels I2.

The improved hopper indicated" generallyv at I6 is preferably made of sheetI metal and is rectangular in cross section with a base portion Il and an outwardly dared upper mouth portionl having suitable handles I9 on the sides ther'eofl The means for slidably and removably mounting. the hopper I6 on the standard I3 preferably includes a U-shaped bracket mounted on therear walls of the hopper, and having sideplate's 20' with flanges 2l at their'inner ends secured as by welding to the hopper, with metal plates orstrips 22 extending between the rear ends of. the plates 20 at their top and bottom edges.- These metal strips- 22 are provided withk U-shaped channels or guides 23 at theiry ends,.which.areadapt`ed Ato engage around the outer edges of the legs I4`a of the standard yto provide a sliding mounting for the hopper I5 on the standard. Since the Alegs `Illa of the standard extend continuously. to the top, the hopper I6 is easily removed by moving it upwardlyv until the channels 23 clear the Ylegsldci.

The. novel friction clamp for. normally locking the hopper in adjusted position on kthe standard preferably includes a latch bar 24 pivotedto the lower strip -22 at one side thereohwiththe. outer end portion of the lever extending through a notch 25 formed in the opposite vsidewall 20 and said lever having a reverse flange 2.6 onitsouter end engaging aroundfthe outer edge of oneof the angle legslda. A tension spring 2'I hasts-lower end connectedto an intermediate portion ofthe levery 24 and its upper end connected to the upper strip 22 so that the spring normally urges the llatch bar 24 upwardly andL causes the reverse flange 26 to wedgeably and frictionallyrengage the leg Ilia of the standard and lock the hopper to the standard in adjusted position.

A releaselever 28 is secured at its. bottom'end to the inner endfof the lever 2l!andV extends Iu-pwardly therefrom between the side walls 2U ofthe mounting bracket and behind the upper strip 22. When it is desired to'release the-latch v211 from locking engagement with the standard.,` the upper end of the release lever 28 is.A rocked or moved to the left as indicated in Fig. 3., or. tothe right as indicated in the rear elevation Ain Fig. Y5. Such movement depresses the outer` end -26 `oli the lever 24 about its pivot and releases itwfrom engagement with the standard.

The means for engaging the mouth of the sack and holding itin open position around thebase of the hopper preferably includes a front rod-3D soldered or welded to the front wall of-.the .base of the hopper and a rear rod 3l similarly secured to the rear wall of the hopper. The ends of 'the rods 30 and 3I project slightly beyond the side walls of the base of the hopper and'aresllightly bent upwardly to form prongs 30a and'3la 'which are adapted to engage the fabricofthe mouth of the sack S forholding it in openposition around the hopper so that grain or produce orany other material can be filled into the sack through .the enlarged or funnel mouth I8 of the hopper.

A gravity latch 32 .is preferably pivoted at'one corner of the hopper base and hasa depending arm 33 which is adapted to drop over and clamp or grip the fabric of the bag which is hooked over the adjacent prong 30a. In this way, the fabric of a sack mouth which is larger than the hopper base can be overlapped under the gravity latch 32 and may then be held or gripped vby the engagement of the arm 33 over the adjacent prong.

In Fig. 6 there is shown a sheet metal extension 35 which depends downwardly from the hopper bas'ef I1 and is tapered"i inwardly at itsV bottom end as at 36 for receiving the upper'ends'of paper bags of various sizes. The extension 35 prefer- 1 ably telescopes over the hopper base at its upper `gravity .latch 32.

end,I and may be secured thereto by hooks 31 which are pivoted on the extension and engage over the rprongs a and 3Ia. Thus, the hopper I6 can be used to fill various sizes of paper sacks by'holding the upper end of the sack over the bottomof the extension and pouring the material into the open mouth of the hopper.

In using the improved sack holder for filling .large sacks of yvarious sizes witha variety of'materials, the sack is quickly attached to the base ofthe hopper by hooking ,the fabric of they-mouth of the sack over the prongs 3'0lvand 31a, and lapping the slackmaterial and gripping. it under the The material is then quickly poured through hopper mouth 'I8`to 4iillthe sack, and beforev or after: llin'gthe sackholder` may be. quickly and easily movedfrom place to place by grasping the handle I 5a and tilting. the holder f slightly rearwardly so that .it is rollably. supported on the wheels I2. The sack S is quickly. and easilyY removed by lifting; the latch 32- and. unhooking` the bag mouth fromthe prongs-30m and 3Ia,=\-andl a sack of different llength isfquic-kly acquickly removedA by. holding the' lever'28" in relea'sedlpositi'on and sliding the hopper upwardly unti-lthe lstrips` 22 clear the top 'o'f 1 thefstandard.

Accordingly, the improved sackl holder is`i1`i expensive and light inweight-soas to facilitate easy-:handling and portability, and is adapted-for quicklyand easily accommodating'sacks of -various lengths and girths so as to provide for' filing a largenumber of f various sizes of sacksin the shortest possible time;
