Claims. (01. 226-59) to make this task more easy. However, most us-'.

ually, sacks are still filled by emptying the onions, potatoes, or like products into the mouth of the sack, from the top of a tilted basket, hamper, or similar container.

In view of the above, it is the main object of the present invention to provide a device capable of being readily attached to the open end of a sack, and adapted when so attached to permit the sack to be filled swifty, and with a mini-mum amount of difficulty.

Another important objectfis to provide a device as stated which will be in the form of an open ended, tapered, basket-likebody having means disposed at substantially diametrically opposite locations thereupon that are'adapted to engage the open end of the sack and hold said open.

end in position about the body, thus to permit the objects with which the sack is to be filled to pass directly through said body into the sack.

Another important object is to provide a device of the character referred to wherein the means employed thereon for engaging the sack will be relatively adjustable-in a manner to cause the open end of the sack to be tensioned about the body.

Yet another object of importance is to provide a device as stated wherein the adjustable means will be so formed as to be retained automatically in selected positions to which the means is adjusted, with disengagement of said means from the sack being adapted to efiect an automatic release of said means from the selected position to which it was previously adjusted.

Still another object of importance is to provide a sacking device which can be manufactured at relatively low cost, and will be rugged and durable in use.

Other'objects will appear from the following description, the claims appended thereto, and.

from the annexed drawings, in which like reference characters designate like parts throughout theseveral views, and wherein:

Figure 6 is a sectional view taken on line 6--6 of Figure 5; and

Figure 7 is a sectional view taken on line 'l| of Figure 5.

The sacking device formed in accordance with the present invention includes an open ended, basket-like body designated generally by the reference numeral H3. As shown in Figure 2, the body tapers from end to end thereof, and it will be understood that the body can be formed of any suitable material. As an example of one type of construction which can advantageously be used, I have illustrated the body as comprising a series of vertically spaced, concentric rings l2 of wire material, said rings being increased progressively in diameter from the smaller to the larger end of the body and being fixedly secured in spaced relation by a plurality of longitudinal braces ll spaced circumferentially of the rings and arranged longitudinally of the body. The support braces 14, like the rings l2, can be formed of a stout wire or rod material.

Mounted upon the outer surfaceof the body [0, at diametrically opposite locations thereon, are sack gripping assemblies designated generally by the reference numerals l5 and I8 respectively. The assembly I6 can be conveniently termed an adjustable assembly, while the assembly I8, for purposes of clarity, will be termed the stationary assembly.

The adjustable sack gripping assembly [6 will be described first, this assembly being illustrated to advantage in Figures 5 to 7 inclusive. As will be noted, the assembly l6 includes an elongated ratchet bar 20 having a longitudinal series of Jnotches 22. The bar 20 is arranged longitudinally I and centrally of the assembly 16, and is rigidly The end plates 24 project laterally and out- 3 wardly from the body, and are rigid, at their outer edges, with the opposite ends of parallel, spaced, longitudinal support rods 28. The rods 26 are disposed at opposite sides of the ratchet bar 20, and are spaced outwardly of the body iii therefrom.

The ratchet bar, end plates, and support rods all cooperate to definea rigidly assembled, elongated, support frame arranged longitudinally of the body Hl.

Circumposed about the support rods 26 (Fig ure '7) and slid-able longitudinally of said rods, are wire loops 28, said loops being rigidly con nected tothe opposite ends of base plate The base plate 36 is thus mounted for slidable adjustment upon and longitudinally of the stipport frame.

Secured fixedly to and overlying the base plate 30 is a support plate 32, one end of which projects beyond the base plate and is inclined as at 34, to facilitate extension into the open end of a sack s'te be filled.

Integral or otherwise made rigid with the support plate 32, intermediate the opposite ends of saidsup'p'ort plate, are the tasted eats extendi ends of a bight it that straddles and extends transversely of the support rods zt (Figure 5).

X It will thus benoted that the piyet pin 3&5, arms 46, extent-warez, and bight 44 can all he formed as a closed loop of stout wire or rod ii '"t'erial, said 19st; being s6 formed as to cause the portioiitt trier-edits be swingable in an alcllat-e' path abodt an axis disposed transversely of the siippoift t me p v I Rigid with the'pin 38, intermediate the a ps. site endslbifsaid pm, is a pawl it, and a spring 43- i s engaged with one of the arms st, and the adja eht ear 36, seas t'o normally bias the pawl thin the; questioner the ratchet-tar 2t.

its other end, the support plate is formed. with spatedhirige sleeves 56, receiving a hinge 5 2, that "extends through a hinge sleeve formed ii'p'ori o'n'e end of a hinge leaf the hinge leaf 55 being thus mounted for swinging move-- tdward steamy from the support plate 32.

The member 563 is formed to an L.-shap'e, one leg of said member being extended transversely or the hinge leaf 54 and being rigidly secured to the underside of said hinge leaf, said leg having cine end projecting beyond one side edge of the hinge leaf and attached to the spring 56.

a any, position to whieh the support.

wgagement with the st The other leg of the member 53 extends longitudinally of the hinge leaf 52, adjacent the other side edge thereof, and is formed at its iree end with an inturned finger Gil.

Secured fixedly to the outer surface of the hinge leaf 54', so as to pivot therewith upon the hinge pin 52, is a sack engaging hook, that can be formed from a single-length of stout wire material folded upon itself as shown in Figure 5, to provide a handle 32 at one end of said hook. At the other end of the hook, the length of wire from which the hook is formed is bent inwardly tsytae the adjacent end of the hinge leaf (Figure 5) to provide a sack engaging prong Gd.

Fix'edly secured to the support plate 32, intermediate the opposite ends of the plate, is a yblre t5 6f inverted U-shape, said yoke having its respective side legs affixed to the opposite side edges of the support plate, the bight oi the yoke overlying the hook described a'ove, Elwingably mounted on said bight is a late an offset fit intermediate its oppodt ends, said a 1 set being adapted to receive the ini'gei of the member 5G,,when theliookis swung t i posi-' tion thereof illustrated in Figure 3, this 'beingah inoperative position of the hook in which it is shifted away from the body i G.'

spring, lid is coiled asset the bi'glit oftle yoke and, is engaged at its opposite ends w h said yoke and the latch member in? respee ely, said spring being so tensi'ohed as to normally urge the latch member into engagement the finger til. I V,

For the purpose of bodily permitting the hiov :able assembly it longitudinally oi its asset] ted support frame, I. provide a tr l'oop lik'e handle '52, which can be formed from a st 318 length of wire material having its tiveenss pivotally supported upon the base plate 39.

From the construction which has far tees illustrated and described, it will be apparent that the prong as will be normally urged in the direction of the body at, so at to grip the sack .8 when the body it is positioned in the ihehth of the sack in the manner illustrated iii Figure 3. It will be further noted. thatwhen the prong ts is shifted into engagement with the sacl:,"the pawl 56 will be biased by its associated spring it into engagement with a selected notch 22 of the ratchet bar. Thus, when the body l't is'posi 'tioned within the month of the sack, the latch member holding the hook out of'ehgageinent with the sack, the first step won ldlfe to trip the latch member at, thus to cause the prom; M to be'swung fer'cibily into easement with the sack. Thereafter, the user g: bail or handle 52, and pulls upwardly th so as to shift the entire adjustable hbly toward the larger of th'bo zifta- -the assembly has been 'o'ved to desired eirte'n't, the handle i2 is released, and the "15 W1 56 will' be engaged in a selected n o t'chdfi of the ratchet To assure the retentieii' tr th th" support site," :is formed Witha ap r'tii're" l3, prong "623' will'h ov'e w on the "to its operative, engaging tartan.

At such time as the each is to be releaseithe "user depresses the handle of the heck, swingpawl 46 is swung out of engagement with its associated notch 22. a

For the purpose of reinforcing the fixed connection of the support frame to the body i ii, and also for the purpose of guiding the end of sack onto the tongue 34 of the support plate 32, angularly disposed braces hi are provided, that are secured to the lower end plate 26, and extend to the lower end of the body Id Referring now to the stationary assembly It, essentially, the construction thereof is the same as that of the adjustable assembly 16, with the exception that the ratchet and pawl means is omitted, and with the further exception that the assembly is not adjustable in the direction of the opposite ends of the body. Thus, a stationary support frame is provided, that includes angular braces 78 which, like the braces 14, serve to guide the sack to its proper position, said braces 78 being rigid with support rods 19, said support rods being fixedly secured to the body I 0.

At the upper ends of the support rods 19, hinge sleeves are provided, receiving a hinge pin Bil, to provide a pivotal mounting for a hinge leaf 82 that constitutes a pivoted hook, by reason of the provision of an inturned, sack engaging prong 84 at the free end thereof.

A handle 86 is included as part of said hook and is rigid with the hinge leaf 82. pression of thehandle 86 will effect disengagement of the prong 84 from the sack S. However, release of the handle 86 will cause the prong 84 to swing into engagement with the sack, it being understood that a suitable spring will be provided, arranged like the spring 56 of the assembly l6.

Rigid with the support rods 19 is a yoke 88 to the bight of which is pivotally connected a swinging latch 90 having an ofiset intermediateits opposite ends adapted to engage a suitable projection provided on the hinge leaf 82.

It will be noted from Figure 2 that the stationary assembly [8 is disposed adjacent the lower end of the body Hi.

In use, the entire device would be positioned in the open end of a sack S, and the prong 84 will be shifted into engagement with the sack. The adjustable assembly l6, meanwhile, will have been adjusted toward the lower end of the support frame, and the prong 64 is swung into engagement with the sack, at a location diametrically opposite that at which the sack is engaged by the prong 84.

As a next step, the bail 12 is grasped, and pulled upwardly, as a result of which the open end of the sack, at one side thereof, will be pulled upwardly. It is to be noted, in this regard, that the upward movement of the prong 6-4 will cause the open end of the sack to be tensioned about the body Hi. This is due to the fact that the movement of the adjustable assembly 16 will cause said assembly to move away from the stationary assembly l8, not only longitudinally of the body, but also, due to the tapered formation of the body, diametrically of the body,

The tensioning of the sack S is thus efiected, since the sack is drawn upwardly at one side thereof along a tapered, progressively widened body.

After the open end of the sack has been tensioned about the body Ill in the manner discussed above, the body is filled with onions, potatoes, or any other article with which the sack is to be filled (Figure 3).

The user then need merely lift the body I!) Thus, de-

upwardly, as a result of which the articles contained therewithin will empty into the sack S. It is to be notedthat in lifting the body 10, the worker does not lift any appreciable weight, since the articles contained within the device will be continually deposited within the sack, simultaneously with the lifting action. a a I When the device has been fully emptied, as in Figure 4, the worker depresses the handles 62, respectively, causing the prongs 64, 84 to be disengaged from the sack. The disengagement of the prong 64 from the sack is accompanied by a simultaneous disengagement of the pawl 46 from its selected notch 22, permitting the entire slidable portion of the adjustable assembly to gravitate to its normal, lower position. Gravitation of said portion to its low position is provided for automatically, because depression of the handle 62 will cause the latch 66 to engage automatically with the finger 60.

a It is believed apparent that the invention is not necessarily confined to the specific use or uses thereof described above, since it may be utilized for any purpose to which it may be suited. Nor is the invention to be necessarily limited to the specific construction illustrated and described, since such construction is only intended to be illustrative of the principles of operation and the means presently devised to carry out said principles, it being considered that the invention comprehends any minor change in construction that may be permitted within the scope of the appended claims.
