Patented May 13, 1941 UNITED STATES 'ATENT OFFICE The present invention relates to a bag filling device and more particularly to a device for use in packaging potatoes and other similar products.

The primary object of the invention is to provide a vegetable sacker embodying means for eliminating dirt and dust from entering the sack by conveying the vegetables over a stationany-and movable support which tends to dislodge dirt and dust therefrom resulting in the packaging of substantially clean vegetables.

Another object of the invention is to provide a bag filling device which provides for a rapid packaging 01f the vegetables with a minimum amount of time and efiort on the part of the operator, the device operating substantially automatically to convey the vegetables from the source of supply and discharging the same in a bag or sack supported at the discharge end.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawings which form a part of the application.

In the drawings Figure l is a top plan view with parts broken away to illustrate interior parts of the device.

Figure .2 is a longitudinal sectional View taken substantially on line 2-2 of Figure 1.

Figure 3 is a partial sectional View taken substantially on line .3--3 of Figure 2.

Figure 4 is a fragmentary sectional View taken on line 474 .of Figure 2, and

Figure 5 is a detail view of the chute attaching plate mounted on one end wall of the device.

The herein described invention finds its greatest use in a retail store where vegetables and similar products are sold in relatively! small quantities and which are normally packaged in paper bags. At the present time, it is customary for the clerk in the store to package such products, by hand resulting in the soiling of the hands and a resultant loss in time in handling the required amount of vegetables to meet the specific sale.

The present invention includes a hopper having a pair of racks angularly positioned therein on which the vegetables to be sacked are de- 4 One of the racks is adapted to agitate upon the actuation of the discharge spout movably supported on one end of the device. Agitation of the vegetables removes the dirt and dust accumulated thereon providing for the packaging of vegetables substantially free from dirt, dust and the like. The discharge spout is movable to control the discharge of the vegetables and at the same time actuate the agitating rack.

Referring to the drawings for a more detailed description thereof, the device therein disclosed includes a substantially rectangular shaped hopper H] supported on leg members H attached thereto by any desired means. Supported in angular relation on the upper edge of the hopper walls by means of the clamps I2 and I3 is a rack [4, said rack being formed of a plurality of bars l5 which form a grate-like structure substantially the same width as the hopper and adapted to fit within the walls thereof, as clearly shown in Figure 1 of the drawings. The bars ii are connected in a manner to be removable from the rack M, the bottom wall of said rack being substantially solid to form a receptacle for receiving any dirt or dust dislodged from the vegetables placed thereon.

, For supporting a second rack It at an angle opposite to the rack l4, there is provided a pair of flange bars I! attached to each side wall of the hopper l0, one of the flanged bars being shown in Figure 2 of the drawings. The rack 16 also comprises a series of spaced bars I 8 to form a grate-like construction, said bars being attached to the member l9 on the sides of which are mounted rollers 20 adapted to engage the flanged bar I! and permit reciprocatory motion of the rack l6. A tension spring 2| attached to the end wall of the hopper at 23 and to the member H3 at 24 returns the rack I6 to normal position. It is to be understood that potatoes or similar vegetables are first deposited on the rack l4 and are fed by gravity on to the rack l6 for discharging through the spout of the hopper. Since the rack I! is adapted to agitate,

dirt, dust or the like remaining on the vegetables will be dislodged and caused to deposit in the compartment 25 disposed beneath said rack IS, a trap door 26 being provided for the cleaning of said compartment.

ment of the rack 16 during agitation thereof.

The discharge end 28 of the hopper IB is partially closed from the top toward the bottom by mean of the plate'3il suitably attached to said hopper, the space between the bottom of the hopper and the end of the plate forming a discharge opening 3|. An arcuately curved member 32 is attached to the side walls of the hopper and in close proximity to the opening 3| for directing the vegetables discharged from the rack l6 into said opening. It will be noted that the inner end' of said member 32 terminates adjacent the end of the rack i6 so that the vegetables can bereadily discharged thereon.

The bottom wall 33 of the hopper I forms the bottom of the compartment 25 in which dirt, dust and the like from the vegetables is deposited. The bottom wall 33 preferably extends at an angle toward the discharge opening and one end 34 thereof is secured to the frame member 35 and terminates a slight distance beyond the grate l6. A guiding trough 36 is hinged at 31 to the end 34 of the bottom plate 33 and is adapted to direct the vegetables discharged through the opening 3| into the bag or sack'supported beneath the lip 38, said lip being fixedly secured at 39 to the free end of the trough 36, the lip forming a part of the hood 4| which entirely surrounds the free end of said trough. To prevent the vegetables contacting the trough 36 from being discharged on either side thereof, there is carried by said trough and on both sides thereof a flange-shaped member 40 best shown in Figure 4 of the drawings.

The hood 4| is especially shaped so as to convey the vegetables discharged through the opening 3| into a bag or sack supported beneath the lip 38. The hood 4| and trough 36 are adapted to swing on the hinge 31 and to return the same to normal position, there is provided a tension spring 42 attached at one end 43 to the plate 30 and the other end 44 to the hood 4|. The tension spring 42 returns the hood and trough to normal position when pressure on the hood has been released. The rack I6 is adapted to reciprocate upon movement of the trough and hood, this action being accomplished through the use of a metal strip 43' attached at 44' to the rack l6 and at 45 to the top surface of the trough 36. It can be readily seen that movement of the trough will impart movement to the rack I6 through the plate 43, the tension springs 2| and 42 returning the movable members to their normal position.

It may be desirable to alter the size of the opening 3| to regulate the speed of the vegetables being discharged therethrough and to accom plish this purpose there is provided a plat 46 fixedly attached at 41 to the end plate 33 and diverging at an angle therefrom. The plate 46 is arcuate shaped having a rounded central portion and adjustably supports on the end thereof the plate 48, said plate being slotted at 49 and adjustably held on the plate 46 by the fastening means 50. The plate 48 is movable through the slot 49 and fastening means 50 to adjustthe opening 3|, it being understood that the plates 46 ancl'48 are suspended over the opening as clearly shown in the drawings.

In the operation of the device, a bag or sack to be filled is first positioned on the floor or other level surface beneath the lip 38 of the hood 4|. A supply of potatoes or other vegetables has previously been supplied to the hopper ID by deposit on the rack M where they are fed by gravity to the rack E6. The hood 4| is pressed downwardly from the dotted line position shown tion which causes the vegetables to be discharged from the rack l6 through the opening 3| and trough 36 into the sack. Should the opening 3| become clogged, pressure on the hood 4| can be released allowing the spring 42 to return the same to normal position and by again depressin the said hood the grate I6 will be actuated to release the vegetables for continuing the packaging operation. As previously indicated, agitation of the rack l6 will help to dislodge dirt from the vegetables thereby presenting a clean packaged product.

Also it will be understood, of course, by those skilled in the art that variations in the herein- :above described device involving the substitution of substantial equivalents for the devices described are intended to be comprehended within the spirit of the present invention and that the invention is capable of extended application and is not confined to the exact showing of the drawings nor to the precise construction described and, therefore, such changes and modifications may be made therein as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.
