CARL G. G. BERGSTROM, OF ST. PAUL, MINNESOTA.

BAG-HOLDER.

Application filed August 31, 1916.

Edit whom it may concern:

Be it known that I, CARL G. G. BERG- 'STROM, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Improvement in Bag-Holders, of which the following is a specification.

This invention relates to certain new and useful improvements in holders for sacks and is particularly designed to engage and retain themouth of the sack or bag in distended or in open position, so that it may be fimost conveniently filled and packed with grain, articles or produce of whatever nature; and as such includes features of improvement over the construction illustrated and described in-my Patent Number 1,280,- 060, granted to me on the 12th day of June, 1917, for bag holders.

One of the improved features of the present invention is the provision of novel means whereby the bag holding elements may be initially positioned or adjusted to approximately the size of the mouth of the sack or bag to be filled. Another object is to provide means for engaging the mouth of the bag so that the same may be quickly attached about the bag-holding elements and in such manner that the tension about the bag mouth is evenly distributed so as to most effectively extend it for filling and to minimize the likelihood of ripping or tear ing of the bag.

A further object is to provide a novel means of mounting the bag engaging devices so as to avoid the possibility of personal injury to the operator or damage to the goods being put into the bag.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claim.

In the drawings, Figure l is a side elevation of the invention showing a bag in filling position held thereby; Fig. 2 is a partial section taken on the line XX of Flg. 1 looking'in the direction of thearrow, show ing the bag holding elements 1n sllghtly' furtherextended position than as illustrated in I Fig. 1; Fig. 3 is an enlarged section taken on the line YY of Fig. 2, showing the housing and bearing, the latter in dotted lines, for one of the bag engaging members, and Fig. 4: is a detail,'partly in section and broken away, of a'portion of the carriage Specification of Letters Patent.

Serial No. 117,822.

mechanism supporting the movable bag holding element.

Like numerals of reference refer to like parts in the several figures of the drawings.

In the drawing illustrating this invention, the reference character A represents a base or platform upon which is mounted a standard B comprising a support 10 rigidly secured in any desired manner to the base, and a tubular or other shaped member 11 telescoping and longitudinally movable upon the said support. These parts are fully set forth in my copending application, Serial Number 93,071, filed April 24, 1916; but for the purposes of this application, certain of the specific features of construction of said parts'will be here described.

The tubular member 11 is formed of two sections 12 and 13, the upper extremity of the section 12 being enlarged as shown at 14 to receive for securance in any preferred method, the lower extremity of the section 13. Pivotally secured between a pair of outstanding lugs 15 (only one of which is shown) is a dog 16 held in engagement with longitudinal waved serrations 17 formed on the support 10 as fully described in my copending application above referred to. By this means the member 11 may be moved vertically upon the'support 10 and retained in selective position as and when desired.

Attached about the section 13 of the mem ber 11 is a collar 18 from which extend one or more arms 19 supporting at their outer free ends a bag holding element 20 made of any suitable material and configuration, though here shown of segmental contour. At each of its opposite ends, the element 20 terminates in an outstanding portion 21 having an aperture through which a tubular member 22 is adapted to slide for a purpose which will later appear. Telescoping with in each of the members 22 is an elongated rod 23, to the outer free ends of which rods are secured the outstanding portions 24 of a second bag holding element 25 here shown as similar in construction and shape as the element 20 above described. It is to be un derstood that the segmental contours of the elements 20 and 25 extend in opposite directions. At their corresponding ends, the members 22 are each provided with a threaded opening, through which a setscrew 26 operates to bind, upon and hold the rods 23 in different extended positions.

--by1means-'ofa' threaded bolt 28, (seeFig.

3), a toothed wheel 29 adapted to revolve in a substantially horizontal plane and to ..retain in position thereon a'portion of the to engage andhold the bag, it is equally month of the bag or sack to be filled. IVhile it is necessary that the teeth of 'the'wheels 29 project a'sutficient distancebeyond the outer convex faces ofthe'elements'20 and necessary that the portion of the wheels V which extends inwardly, be-protected from clogging vby small grain, -or other articles deposited-in the bag, andto eliminate possibility ofpersonal injury-to the operator or damage to the goods being-put into the bag.

-For' this purpose, the enlargements 27 are provided, it being understood that at their base, the enlargements are of sufficient size to entirely cover the inwardly extending portions of the wheels. By forming-theen- -largem'ents of inverted semi-cone shape,

thereis no possibility of the retention-there on of any of the produce being put into the bag.

7 At their: free ends each; of the tubular members 22 is pivotally attached to the end of the long arm'30 of-a bell crank, the angle portion ofwhich is journaled between two lugs 31 (only one being shown) extending outwardly from a yoke 32 having integral projections 33 suitably engaging the support '10 for reciprocable movement thereon. The yoke 32 also has a projection 34 to which one end of a spring 35 is secured, the other end of the spring being attached to the endof the short arm 36 of the bell crank. By the construction just described, the tension of the spring 35 will cause the element 25 to move forcibly away from the stationary ele ment 20. As more fully set forth in my copending application, the apparatus includes evener'rods 37 (only one being here shown) pivoted at one end to the collar-18 carried by the tubular section 13 and the other end to the long arm 30 of the bell crank, the object of such evenerrods being to effect aneven up or down movement to theyoke 32 when the movablebagelement and its supporting or carriage mechanismis moved in toward or away from the stationary-bag element and 'to thus eliminate'any binding tendency of the parts in their several movements.

done, and the set screws 'retightened, the

bag element 25 is forced inwardly against the tension of the spring 35 asuflicient' distance to enable the bag mouth'to be'secured" about-the several wheels 29 'onb'oththe'elements when the force a'gainst'the element 25 is removed and such element thrown outw'vardly by the action of spring'35 so'as to {the bag'mouth is evenlydistributed, so that there is no'saggingof the bag orany' likelihood of its being ripped or torn. In accordance with the patent statutes, I have described theprinciples of ope'ration of-my invention, together with the apparatus which I now considertorepres'ent the best embodimentthereof, but I desire to T have it understood that the construction shown is only illustrative, and that the invention can be carried out by other means and applied to uses other than those'above set forth within the scope of the following 1 claim. 7

Having described my. invention, what I claim as new and desire to' protect by Letters Patent is: j

A bag holder, comprising, in combination, a standard, a plurality of, bagholding elements supported by said standard, oneof said elements being movable awayrfrom the other, and both of said elements being fiat upstanding bands of segmental contour extending in opposite directions, and a series ofclosely placed freely rotatable bag engag ing elements journaled onthe lower-edge of each and projecting inwardly and outwardly from the concave and c'o'nvex'sides of said bands to tensi'onally engage-and retain in curved open position the mouth 'of a bag and to evenly distribute the-tension. about the bag mouthysaid bands being formed with-guides over the instanding portion of each rotatable bag engaging, element.

In testimony- "whereof, I have; signed my name-to this specification.
