Specification of Letters Patent.

Application filed January 11, 1912. Serial No. 670,539.

To all whom it may concern Be it known that I, ADoLPH DAHLSTROM, a citizen of the United States, residing at Amery, in the county of Polk and State of Wisconsin, have invented certain new and useful Improvements in Bag-Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7

My invention has for its object to provide an improved bag holder, and to this end, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the. several views.

Referring to the drawings,Figure 1 is a plan view of the improved bag holder with some parts broken away and with other partsshown in different positions by means of dotted lines; Fig. 2 is a side elevation of the improved bag holder with some parts broken away and with other parts shown in vertical section; and Fig. 3 is a detail View, on an enlarged scale, showing the adjustable lock forthe bag supporting arms.

The numeral 1 indicates a portable base or platform provided at one end with a rectangular opening or seat '2 ada ted to receive a correspondingly formed s ank 3 formed on the lower end of a vertically extended post or standard 4. The lower end of the standard 4 rests on the base 1 and its shank 3' detachably holds the same in a vertical position and against rotation. A brace rod 5 is securedat its intermediate portion to the standard 4 by means of a bolt 6, and its ends diverge forwardly and downwardly and are detachably secured, one to each side of the base 1 by means of screws or otherwise. I

Mounted inthe standard 4, for vertical adjustment, is a supporting head 7. This supporting head 7 is provided with a pair of rearwardly and horizontally extended spring arms 8 arranged to embrace the standard 4. The free ends of thearms 8 terminate in a pair of'laterally spaced and rearwardly extended ears 9. A horizontally extended clamping bolt 10 is passed through the ears 9 and is provided, at its projecting end, with a thumb nut" 11 having screw threaded engagement therewith. As is evident, by tightening the thumb nut 11, the spring "arms 8 may be frictionally clamped onto the standard 4 for holding the supporting head 7 in difierent vertical adjustments.

Secured to the supporting head 7, is a horizontally extended bar terminating at its ends in a pair of vertically extended hinge lugs 12. Carried by the supporting head 7, is a pair of cooperating and re- Versely formed semi-cylindrical bag sup porting arms 13 having secured to their outer sides, a multiplicity of outwardly and downwardly projecting bag engaging hooks 14. These hooks 14 are laterally spaced apart and are adapted to be hooked into the upper edge of a bag Y, as best shown in Fig. 2.

The bag supporting arms are preferably made of quite heavy spring metal, the purpose of which will presently appear. To the inner ends of the bag supporting arms 13, are rigidly'secured a pair of hinge lugs 15 having interlocking and pivotal engagement with the hingelugs 12. A pair of upwardly projecting eye bolts 16 are secured bag supporting arms 13 in open positions.

The rear ends of the bag supporting arms 13 are extended rearward slightly beyond their hinge lugs 15 to form stops 19 adapted to engage the spring arms 8 to limit the opening movement of the bag supporting arms 13.

On the inner face of the supporting head 7, is secured a horizontallyextended bar 20, the ends of which are bent tofo-rm a pair of oppositely projecting stop lugs 21. These stop lugs 21 are adapted to engage stop shoulders 22 on-the inner faces of the bag supporting arms 13' to limit the closing movements of said bag supporting arms. The stop lugs 21 and stop shoulders 22are so arranged as to limit the closing movements of the bag support-ing arms 13 and to hold their free ends laterally spaced apart in predetermined set positions, as shownin' Figs. 1 and 3. i r

Pivotally secured at 23, to one of the bag supporting arms 13, is a lock bar 24, and i Patented May 28,1912.

mounted in the other of said bag support-ing arms 13, is a transversely horizontally extended clamping bolt 25 provided with a thumb nut 26. The lock bar 2 is adapted to span the opening between the freeends of the bag support-ing arms 13, when in their closed positions. At its free end, the lock bar 24 is provided with a thumb piece 27, and, in its under edge, is formed a multiplicity (as shown three in number) of laterally spaced notches or open seats. 28. These notches 18 are adapted to embrace, one at a time, the clamping bolt 25. It is evident, by tightening the thumb nut 26 on the bolt 25, the lock bar 24- may be clamped onto the adjacent end of the bag supporting arm 13. hen the bag supporting arms 13 are in their predetermined closed positions, the notch 28 nearest the thumb piece 27 embraces the clamping nut 25 and holds the bag supporting arms locked together. In case the bag Y is of an unusually small size, the bag supporting arms 13 may be sprung together and either one or the other of said notches 2S brought into engagement with the clamping bolt 25, depending on the size of the bag. In case an unusually large bag Y is to be attached to the bag supporting arms 13, the lock bar 24: may be moved to an inoperative position and the bag supporting arms 13 held in engagement with the bag Y under the tension of the spring 18.

From the foregoing description, it is evident that a bag holder constructed in accordance with my invention may be shipped in a knocked down condition and then put together very quickly by the use of a few tools.

\Vhat I claim is:

1. In a bag holder, the combination with a supporting head, of a pair of bag supporting arms, one of which has a hinged connection to said head, an abutment operative on said hinged arm, near its hinged connection, for stopping the same in its normal closing movement, in a predetermined. position, said hinged arm capable of being further sprung beyond said predetermined position, and adjustable means for locking said hinged arm in positions closed beyond said predetermined position.

2. In a bag holder, the combination with a supporting head, of a pair of bag supporting arms having a hinged connection to said head, a spring tending to open said arms, means for stopping the normal closing movements of said arms in predetermined positions, said arms capable of being further sprung together beyond such predetermined positions, and means for locking said arms together, in and beyond said predetermined posit-ions.

3. Ina bag holder, the combination with a supporting head, of a pair of bag supporting arms having a hinged connection to said head and also having bag engaging elements, a spring tending to open said arms, means for limiting the opening movements of said arms means for stopping the normal closing movements of said arms in predetermined positions, said arms capable of being further sprung together beyond such predetermined positions, and means for locking said arms together, in and beyond said predetermined positions.

4. In a bag holder, the combination with a standard and a suitable base therefor, of a supporting head mounted on said standard for vertical adjustment, a pair of bag supporting arms having hinged connection to said head and also having bag engaging hooks, a spring tending to open said arms, 'a stop for limiting the opening movement of said arms, a clamping bolt secured to one of said arms, and a notched lock bar pivotally connected to the other of said arms and hav ing interlocking engagement with said bolt for holding said arms in different closed positions.

5. In a bag holder, the combination with a supporting head, of a pair of bag supporting arms having hinged connection to said head and also having bag engaging elements, a spring tending to open said arms, means for limiting the opening movements of said arms, means for stopping the normal closing movements of said arms in predetermined positions, said arms capable of being further sprung together beyond such predetermined positions, a clamping bolt secured to one of said arms, and a notched lock bar pivotally connected to the other of said arms and having interlocking engagement with said bolt for locking said arms together in and beyond said predetermined positions.

In testimony whereof I afliX my signature in presence of two witnesses.
