ROBERT I. MoNAUGHTON, or Minor, Norma DAKOTA.

SACK-HOLDER.

To all whom it may concern:

Be it known that I, ROBERT I. MCN'AUGH- TON, a citizen of the United States, residing at Minot, in the county of WVard and State of N orth Dakota, have invented certain new and useful Improvements in Sack-Holders, of which the following is a specification.

This invention relates generally to improvements in devices for bagging grain, etc, and more'particularly has reference to an improved sack holder.

It is the principal aim and object of the present invention to provide a device of the above mentioned character designed for supporting a sack or bag and for holding the hemmedmouth thereof in an extended posi-' tion while grain or the like is being placed into the same while the component parts of the holder are of novel construction and are capable of being moved relative to each other for insuring of the removable clamping of the sack in position and at the same time the parts are relatively adjustable so that various sized sacks may be clamped in a supported position.

More particularly this invention consists inthe provision of a device of the above mentioned character wherein clamps of improved construction are mounted'on the :vertically adjustable main support and designed to cooperate with the supporting 'yoke'or bail in such a manner that the yoke or bail may be removed therefrom when 1tis not desired to use the device; swung into a'raised position relative thereto to permit of the clamping of the bag or sack in the proper position; and also slid to insure of the proper clamping of sacks of various sizess It isa more specific object of the present invention to provide a device of the above mentioned character wherein improved resilient means is designed to coiiperate with the clamping bracket and the adjacent portion of the bail or yoke for frictionally retaining the bail or yoke in an adjusted position.

Among the other aims'and objectsof the present invention may be. recitedthe provision of a sack'holder'of the above mentioned character wherein the number of The improvements in the details and arrangement of parts will be apparent from Specification of Iletters Patent.

an inspection of the accompanyingl'draw ings, 1n connection with the specific descrip-v tion hereinafter contained, and wherein the preferred embodiment of the invention is disclosed for the purpose of imparting a full understanding of the invention; v

The invention is clearly illustrated in the accompanying drawings, in which:

Figure 1 is a perspective View of the holdersho wing a' sack clamped in a supportedposition,

Pg. 2 is a perspective detail of one of the clamps, I

Fig. 3 is'ajvertical longitudinal sectional detail through oneof the clamps,

Fig. 4 is a rear elevational' detail of one of the clamps.

Similar charactersof reference are em: ployed in all of the above described views, to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings, there is provided a standard l to which'is adjustably connected for vertical movement a cross bar 2, connection being preferably maintained. between the barandthe standard throughthe instrumentality of a bracket '3 which is 's'e-,

cured to the bar by suitable fastenersgland designed to slide vertically on they standard and h'eld'invarious positions of adjustment thereon by fasteners 5 which removably' en; gage the bracket and standard and con'sef quently support the bar; v V

With a view toward providing the i'mproved clamping means there isemployed: a pair of brackets each indicated in its'enpose that will presently appear. Spaced jaws 9 and 10 depend from the body, the front'jaw 9 a lining with the front or inner edge of the body while the outer jaw, is V slightly longer and is formed with an opening 11 through which is passed. a fastener;

such as a clamping screw 12 also designed to be anchored in the cross bar when the legs are straddled thereabout, thereby, insuringof the removable clamping of the bracket with the cross bar. Spaced parallel arms 13 project rearwardly from the body and aline with the side edges thereof being joined at their outer ends by an arch 14, preferably 7 portion 2-1 and a resilient portion 25.

integral therewith and this arch. the arms and the body 7 form an opening 15 for a purpose which will presently appear. The rigidity of the arms is increased by means of the integral braces 16 which are preferably joined with the under surfaces of the arms and the adjacent faces of the jaw 10 at the sides thereof. It is also to be noted that the inner edge of the body 7 is formed with an inwardly extending slot 17 which leads from the opening 15, for a purpose which will presently appear. Cooperating with the brackets 6, which are clamped on the bar 2 at opposite sides of the standard 1, is the sack supporting yoke or bail generally designated by the numeral 18 and preferably of a U-shaped configuration including an intermediate portion 19 and spaced side portions or arms 20. The outer extremities of the side portions are designed to be arranged through the openings 15 in the brackets 6 and in clamping the sack or bag 21 the upper hemmed edge is stretched across the cross bar and the body of the clamping bracket being engaged by the opposed longitudinal series of pointed lugs 22 formed on the upper face of each body 7 and preferably near the side edges. When in such position, the bail or yoke is in a raised position and has its intermediate portion 19 engaged against the inner surface of the mouth of the sack beneath the hem thereof. In finally securing the sack, the yoke is swung outwardly and downwardly and slid forwardly the desired extent so that the portions of the sack lying above the recesses 8 will be clamped between the recesses 8 and the side portions 20 of the yoke. 00- acting with the side portions of the yoke are resilient members in the form of leaf springs 23, each of which is preferably right angular in form and consists of an attaching In arranging the springs in position, the attaching or anchoring portion 2% is arranged in the adjacent slot 17 and clamped between the jaw 10 and the cross bar as indicated in Fig. 3, while the resilient portion is positioned between the arms-13 and tensioned toward thearch 1% so as to exert its tension on the adjacent side portions 20 of the yoke and thereby frictionally engage. and retain the said side portions against. accidental sliding movement. These springs however, do not prevent manual sliding adjustment of the side portions so that various sized bags may beclamped and held in a supported position by the device.

It is believed in View of the foregoing description that a further detailed description of the operation of the invention is entirely unnecessary. Likewise, it is believed thatthe advantages of the invention will be readily apparent.

Still further embodiments of the invention than those herein especially defined may be resorted to as conditions or preference may dictate, as may be in keeping with the hereto appended claims. a
