The'vibrator'is shown as somewhat inclined from the vertical. The vibrator may be vibrated for example by the link or connection 8 having lugs 9 carrying pins Ill which interpenetratewith lugs I I extending from the vibrator l. The vibrator may, if desired, be fiat or generally plane, as shown in Figures 1 and 2, or it may be more or less formed to the contour of the bag. It is important that the vibrator be so formed and positioned that the bag X, when-released, will drop downwardly by gravity upon any'suitable c011- veyor l2. The details of the conveyor do n'ot of themselves form part of the present invention but I may employ, for example, an endless cenveyor or belt driven by any suitable actuating means not herein shown, or any other suitable conveyor.

The connection or plate 8 has secured to it a bearing block l4, through which passes the eccentric portion l5 of the power driven sh'aft IS. The shaft may be journaled in any suitabl bearing assemblies H on the base I and may be rotated by a combined pulley and fly wheel 19,

The faces of the

walls

30 and 3| are preferably generally vertical and parallel with the axis of the vertically suspended bag Y. The bag Y may be secured in the same manner as the bag X, except that the spout 20a with its holding flange Zia has a generally vertical axis. The conveyor 12a underlies the bag. It will be understood that the conveyor l2a is moved in the direction of the arrow of Figure 3 so that when a particular bag Y is released, it drops upon the conveyor 12a and is moved by the conveyor outwardly through the open side of the vibrating channel.

It will be realized that whereas I have shown and described an operative device, still many changes might be made in the size, shape, number and arrangement of parts without departing materially from the spirit of my invention. I wish, therefore, that my showing be taken as in a broad sense diagrammatic and illustrative, rather than as limiting me to my precise showing.

Where I employ the term bag in the claim, I wish this term to be interpreted as of sumcient breadth to cover any suitable container which is adapted to be packed by the mechanism and method herein described. It is practical under some circumstances to support boxes, barrels or other containers by an upper portion and vibrate and pack them in accordance with the disclosure herein made. j

The use and operation of my invention are as follows:

In both forms of the device, the bag X or Y is suspended by its upper edge or neck during the filling operation. Any suitable charge of material is released through the spout Zll or 20a into the interior of the bag, the securing means for the bag being effective to support the bag from above and to avoid the necessity of any underlying supporting means for the bag. I have diagrammatically illustrated bag tensioning means 59 in Figures 2 and 4, such as are shown in detail in a co-pending application. The upper edge of the bag is drawn in or tensioned about the spout 20 or 29a which, with the flange 2! or 2la, prevents the escape of the bag until the securing means 58 is released. The bag, during the admission of the charge, and when charged,

is subjected to lateral vibration.

In the form of Figure 2, the vibrating element 6 slightly underlies the bag X, causes gravity to maintain the bag in contact with the member 6 during its vibration. In the form of Figures 3 and 4, the bag is contained between the opposed vibrating walls 3i! and 31, which slap back and forth against opposite sides of the bag and tend to flatten the bag and give it a desirable form. In both forms of the device the bag, when properly charged and packed, is released by releasing the securing means 50. The bag then drops upon the

conveyor

12 or 12a and is conveyed thereby for further handling or disposal. The vibrating member 6 or the members 3!! and 3! guide the bag in its gravital movement downwardly to the move by gravity downwardly upon and be supported upon the conveyor l2 or [2a. The conveyor, whether continuously or intermittently operated, is then effective to remove the bag from the packing area. This is highly advantageous because the packed bags may be heavy and the avoidance of the manual effort of lifting the bag from the packing zone to the conveyor is important. Thus a manual operation is eliminated, with a consequent saving of time and labor and with a speed up in production. The task of manually moving a large filled sack is hard on the laborer and its avoidance is much to be desired. The filled ba can be carried on the conveyor to or through any further stages of treatment Without the necessity of manually lifting the bag.

I claim:

In a bag packer, a base, an elongated vibratory member having an upper end pivotally supported on said base, a drive for laterally vibrating said member including a power driven member on said base laterally offset with respect to said pivotal support and an actuating link connection between the power driven member and the vibratory member for swinging said vibratory member in an arc about the pivoted upper end there of, a bag support positioned adjacent to and above the upper end of the vibratory member, and spaced therefrom, whereby the vibratory member is free to move independently of the bag support, the vibratory member being supported to extend downwardly and outwardly from its pivotal support at an angle toward a bag suspended from the bag support and bein positioned to underlie the bag support and a ba suspended therefrom substantially throughout the arc of movement of the vibratory member, whereby gravity is substantially constantly effective to urge a bag suspended on the bag support toward the vibratory member, said vibratory member having a bag engaging portion extending generally from end to end of the bag, whereby the contents of the bag are simultaneously vibrated from end to end of the bag, the angle of the bag engaging portion of the vibratory member being substantially less than the angle of repose, whereby when the bag is released from the bag support it is free to slide gravitally downwardly along and from the vibratory member, the lower end of the vibratory member being formed to permit the bag to move freely therefrom when the bag is released from the bag support.
