8 Claims.

The invention relates to bag holders and has for its object the obtaining of a construction which is adapted for use with bags of various sizes and shapes; is simple in construction; is

5 inexpensive to manufacture; easily manipulated, and has various advantages as hereinafter set forth.

In the drawings:

Figure 1 is a perspective view of our imlO proved bag holder as in use;

Figure 2 is a side elevation thereof;

Figure 3 is an end elevation thereof.

As illustrated, A is a suitable base preferably formed of sheet metal with suitable reinforcing 15 ribs 3 pressed therein. C is a standard rising from the base which is preferably formed of a pair of angle bars C, C having two of their flanges in spaced parallel relation and the other two in the same plane. The standard is secured 20 to the base by an angle flange D secured to the flanges in the same plane and a gusset plate F arranged between the spaced flanges and attached at its outer end to the base by angle plates G. Spacers H are also arranged between 25 the parallel flanges of the angle bars at suitable points, and bolts I clamp the flanges to these spacers and hold the bars in rigid relation to each other.

J is a bar which extends between the parallel flanges of the angle bars C, C and projects laterally therefrom over the base. This bar J has attached to its rear end the upwardly extending angle bars J, which at their free ends bear against the flanges of the angle bars 0', C

The bar J is also provided on the opposite side of the standard with a cross-pin J which is adapted to be engaged with any one of a series of notches L formed in the parallel flanges of the bars C, C The free end of the bar J has at- 40 tached thereto a spring M which is adapted to resiliently support a hopper N. The lower end of this hopper is of a size which will fit within the mouth of the smallest bag to be filled, being provided with a downwardly flaring flange N 45 for engaging one side of the bag mouth. The opposite side of the bag mouth is engaged by a dog 0 which is slidably supported upon an arm 0 projecting laterally from the hopper and extending to pass between the parallel flanges of A second arm P is attached to the hopper to extend parallel to the arm 0 above the same and which also passes between the spaced flanges of the bars C, C The dog 0 has a portion 0 slidably en- 55 gaging the arm 0' and the flaring segmental flange 0 which engages the bag. There is also a spring Q, one end of which is attached to an upwardly extending finger O on the portion 0 while its opposite end is secured to a member R supported from the arm P by a pair of links R. 5

A pin R extending between these links is adapted to engage with any one of a series of notches P on the arm P, thereby permitting of adjusting both the member R and the dog 0 to various positions.

With the construction as described, to engage a bag with the hopper the member R is firstslid on the arm P toward the standard and the pin R engaged with one of the notches P. One side of the mouth of the bag is hooked over the flaring l5 flange N and the dog 0 is slid forward on the arm 0' against the tension of the spring Q to engage the segmental flange O with the opposite side of the bag mouth. The dog is then released and the tension of the spring will move it rearward to draw the mouth of the bag taut about the flanges N and 0 This will retain the bag in engagement with the hopper, which latter is supported by the spring M preferably attached to the arm P adjacent to the hopper, and the arm J can be raised or lowered on the standard C so as to support the bag with its bottom slightly above the base A. The operator may then fill the bag through the hopper N and when sufficient weight is attained this will draw the bag downward to rest upon the base A, the spring M yielding to permit such action.

In the filling of the bags it may sometimes happen that theoperators shovel will strike the hopper moving it downward, whereupon the recoil of the spring M might have a tendency to jerk the hopper out of engagement with the bag mouth. To avoid such a result we have provided what in effect is a shock absorber to retard the upward movement ofthe hopper and spring. This comprises a pair of links 8 extending between the arms O and P adjacent to the standard C and slightly inclined sotheir upper ends will frictionally bear against the parallel flanges of the bars C, C A pin T engaging the portion of the arm 0 which is adjacent to the rear side of the standard holds said arm against outward movement. Thus, if the hopper is depressed and the spring M placed under additional tension the recoil of said spring willtend to tilt the arms 0 and P in relation to the standard C. This tilting is, however, prevented by the pin T bearing on one side of the standard and the links S bearing upon the opposite sides thereof, the result being that the friction of said links upon the standard is increased, thereby retarding upward movement. In brief, the spring M is permitted to liftthe hopper to its normal position, but this movement is sufliciently slow so as to avoid danger of disengagement from the bag.

The device is easily applied to bags of all sizes, within certain limits, as the operator can use one hand to hold the mouth of the bag in engagement with the flange N, while the other hand can simultaneously move the member R and the dog upon the arms 0 and P until the flange O tightly engages the opposite side of the bag mouth. Also, the arm J can be readily raised or lowered as it is only necessary to tilt it sufiiciently to disengage the pin J from one notch and then to move it into engagement with a higher or lower notch.

To assist in directing into the bag the material discharged from the hopper, an inclined shield U is detachably connected to the rear side of the hopper by means of thumb screws V.

While we have specifically described and preferably employ a hopper to facilitate the filling of the bag, it is obvious that this hopper might be omitted and the bag mouth held open by the frame including the flanges N and 0 What we claim as our invention is:
