BAG-HOLDER.

SPECIFICATION forming part of Letters Patent N'o. 400,191, dated March 26, 1889.

Application filed May 28, 1888.

.To all whom it may concern.-

Be it known that I, EDWARD NV. CLARK, of Rochester, in the county of Olmsted and State of Minnesota, have invented certain new and useful Improvements in Bag-Holders, of which the following is a specification.

My invention relates to improvements in a device for supporting a bag while it is being filled; and the object I have in view is to provide a bag-holder which shall be cheap and simple in its construction and readily adjustable to any size or height of bags, and one in which the bag is supported by spring-pressure which will yield as the bag is filled and avoid undue strain upon the fabric.

My invention consists, generally, in the construction and combination hereinafter described, and particularly pointed out in the claims.

In the drawings which form part of the specification, Figure 1 is a side elevation of my improved bag-holder. Fig. 2 is a front elevation. Fig. 3 is a plan. Fig. 4 is a detail.

In the drawings, 2 represents the base or platform, of any convenient size or construction. A standard, 4, is preferably located at one end of this platform. This standard is preferably formed of a piece of gas-pipe of suitable length and size, and is secured to the platform by a suitable flange, 5, which receives the screw-threaded end of the pipe. A

spindle, 7, also preferably formed of a piece of gas-pipe of smaller diameter, is inserted into the standard 4, in which it is free to slide or turn. A collar, 9, is preferably adj ustably secured to the spindle 7, and is held in position by the set-screw 10. A spring, 12, encircles the spindle 7 and bears against the under side of the collar 9 and the top of the standard 4. A branch or arm, 13, is formed at the upper extremity of the spindle 7, and at the outer end of this arm I prefer to fulcrum the jaws 15, which receive the mouth of the bag. A cross-head, 17, is arranged to slide upon the arm 13, and is secured. in any desired position by a set-screw, 19. The jaws 15 are preferably formed as shown in Fig. 3, their outer curved portions serrated in order to give a better hold for the bag. The rear or straight portion passes through a slot in the Serial No. 275,286. (No model.)

cross-head 17, and a spring, 20, is arranged within the said cross-head and bears between the rear or straight portion of the jaws to throw them apart. By moving the cross-head upon the arm nearer to or farther from the pivotal point of the jaws, they will be thrown farther apart or drawn nearer together, and the size to suit any bag may thus be adjusted, and the spring 2O will hold them out against the bag with a yielding pressure, and also allow for the easy removal of the bag.

The adjustment for the height of the bag is accomplished by means of the collar 9,which may be raised or lowered upon` the spindle 7 to obtain the desired position. In ordinary bagholders,if the bag is allowed to rest upon the plat-form before being lled, a wrinkle is liable to form in the lower portion of the bag, which will cause considerable labor and inconvenience to remove. If, in order to avoid this inconvenience, the bag is raised above the platform, the whole weight of the contents is brought upon the fabric at the mouth of the bag, which will soon give Way. To avoid this inconvenience and provide a means for in suring the proper filling of the lower portion of the bag, I provide the spring 12. It will be seen that the collar 9 maybe adjusted so that the bag when light will be held a short distance above the platform. As the material is placed in the bag and the weight overcomes the tension of the spring the whole will be lowered and the lower end of the bag will rest upon the platform, and all the strain upon the bag will be obviated except that due to the tension of the sprin g. The bag may be turned from one side to the other by swiveling the spindle 9 in the standard 4. The tension of the spring 12 is an advantage when it is necessary to shake the contents down into the bag. This is ordinarily done by lifting the bag a short distance from the platform and letting it drop. In doing this, when the bag is attached to my holder, the spring-tension will aid in lifting the contents of the bag and make it easier for the operator.

Vhat I claim is 1. In a bag-holder, the combination, with the platform, of the standard 4, secured to said platform, a spindle, 7, sliding within the stand- IOO ard and provided with suitable jaws which receive the bag, the collar 9, adjustabl y secured to the said spindle, and the spring l?, acting against the said Collar to partially support the weight, substantially as described.

2. In a bag-holder, the eo1nbination,with a suitable support, of the jaws l5, pivoted upon the support, a spring, 20, for distending the jaws, and a erosshead carrying said spring` 2O and adj ustably secured to the said support to vary the spread of the jaws, substantially as described.

In a bag-holder, the eonibinatioiuwith the plat-form, of the standard 4, secured to said platform, the spindle 7, provided with the ad just-able collar Sl, the spring 12, arranged upon said spindle and resting upon the top of said standard, the jaws 15, pivoted upon said spindle, the adjustable er0ss-head 17, through which said jaws extend, and the sprin 20, arranged within said Cross-head between said jaws, substantially as described.

In witness whereof I have hereunto set 1n y hand this 21st day of May, 1888.
