T 0 all whom it may concern:

Be it known that I, ALBERT EDs'rnoM, a citizen of the United States, and a resident of Duluth, 1n the county of Saint Louis and State of Minnesota, have invented a certain new and useful Improvement in Bag-Holders, of which the following is a specification.

My invention relates generally to bag holders, the uses and functions of which are well known, and more particularly to adjustable devices of this nature which will effectively engage the bag and hold the same firmly open at the top preparatory to being filled, and from which the bag may be readily, quickly, and easily disengaged when desired, and also to make provision for cer tain adjustments which will accommodate bags of various size, both as to length and cross section.

The details of construction, arrangement, and operation of my invention will be hereinafter described and made plain.

In the drawings accompanying and forming a part of this specification:

Figure 1 is a perspective view illustrating the practical application of my invention;

Fig. 2 is a top plan view thereof;

Fig. 3 is a view partly in elevation and partly in section, illustrating the upper portion of my improved holder at one side;

Fig. 1 is an elevation of the upper portion at the opposite side;

Fig. 5 is a detail cross section through the cross bar taken substantially on line 5-5 of Fig. 3;

Fig. 6 is a detail perspective view of one of the adjustable bag engaging teeth of the cross bar;

Fig. 7 is a detail horizontal section taken substantially on line 7--7 of Fig. 4;

Fig. 8 is a detail perspective view of the upper portion of one of the uprights.

Referring now to these figures, my improvementsare mounted upon a pair of' spaced parallel uprights 10, of tubular construction, secured at their lower ends in sockets 11 in which they are threaded, and which sockets are in turn fastened by screws or other suitable fastening means to a platform or other support 12.

At their upper ends the uprights 10 are threaded to receive reinforcing collars 13 and are provided with openings extending therethrough and registering with similar openings of the collar 13', to receive thumb screws 14;, for engagement with the lower stems 15 of the upper heads 16 and 17, which stems depend into the upper open ends of the uprights 10.

The heads 16 and 17, thus adapted for vertical adjustment with respect to the uprights 10, and capable of adjustable fastening by the thumb screws 14, have laterally extending threaded sockets 18'intermediate their ends and turned toward one another for the reception of the threaded extremities of the connecting cross bar 19 provided in its length with a plurality of transverse openings extended partly therethrough and threaded, each of these openings being adapted for the reception of the rounded reduced stem 21 of an angular spur or tooth 22, the other end of which stem is threaded as at 23, in Figure 6, to be screwed into the respective bar opening. The pair of spurs or teeth 22 utilized in practice being thus extended downward and backward. The particular means of fastening the spurs in position enables the bags to be uniformly and rigidly held in a downwardly and rear wardly inclined position, so that their engagement with, and disengagement from, the respective portion of a bag, as seen in Fig. 1, may be readily and quickly effected.

The upper portions of the'heads 16 and 17 are tubular for the reception of the depending steps 25 of T-shaped brackets 26, the upper portions 27 of which are tubular to receive the bag engaging arms 28 in the form of rods having their forward ends bent angularly and outwardly thereupon to form bag-engaging spurs or'teeth 29, the upper tubular portion 27 of each bracket 26 having a thumb screw 30 whereby the respective arm 28 may be adjusted to vary its effective length in connection with bags of different sizes and the head 16 having a laterally extending thumb screw 31 whereby the respective bag engaging arm 28 may be locked in desired angular position by vir tue of the engagement of the thumb screw 31 with the depending stem 25 of the respective bracket 26.

The opposite bag engaging arm 28 is swingablc in and out under tension of a spring 32 coiled about the upper portion of the head 17, and the lower portion of the respective bracket 26, when under tension of the spring being anchored to the head 1?, and the opposite end being anchored to the respective bracket 26, the normal tension of the spring tending to force swinging movement of the respective arm 28 in a horizontal direction away from the arm first mentioned. This swinging movement of the arm 28 last mentioned is limited by virtue of the horizontal slotted opening 33 of its head 17 and the rib 34 working in said slot the spurs or teeth 22 of the cross bar 19 may.

be adjusted to engage one side of bags of different width or diameter and that the effective lengths of thearms 28 may be adjusted to accord with the adjustment of the spurs or teeth 22. It is further obvious that the angular position of the arm 28 at the left side may be changed so that the distance between the two arms 28 will vary to accord with the diameter or width of the particular bag in connection with the holder. V 1

It is observed furthermorethat, not only may these various adjustments be made as above described, but they may be made quickly and easily, without materially impairing the normal strength of theseveral parts of the holder, and without prohibitively increasing its costior detracting from its effectiveness otherwise.

It will also be observed that there is but one arm and one spring which is movable and which is necessary to be moved in order to engage the bag to the bagholder or to disengage the bag. This assures speedin the operation of engaging or disengaging the bag to the holder and the operation is so simple as to be readily and quickly ac complished, and the construction of the invention is such as to hold the sack firmly when on.

It will also be observed that the cross bar 19 acts as a resting spot for the shovel, bag, or basket from. which the bag is being filled.

From the foregoing it is evident that the device is so arranged as to hold one side of the bag higher than the other, and that the filling of the bag is. to be accomplished o the bar 19. The elevationot the opposite edge of the bag away from the bar may be increased if desired, by bending upwardly of the rods 28, or the tubular portions 27 made on an. upwardly inclined angle to suit such desired elevation.

I claim Y The combination with a bag holoer comprising a pair of upright supports, a of heads carried by and adjustable vertically with respect to the upper portion of the supports, across bar. connecting the said heads, a pair of horizontalswinging arms supported on said heads, bag en ag'ing iZQQLll carried by the cross bar and a spring controlling movement of one of said arms, of means for locking the other arm in a predetermined angular position in respect to the cross bar, and against swinging movement in either direction, and means for adjusting .the effective length of each arm separately.
