NORMAN E. GARDNER, OF EASTON, PENNSYLVANIA.

BAG-CLEANING- MACHINE.

oasme.

To all whom it may concern:

Be it known that I, NORMAN E. GARDNER, a citizen of the United States, residing at Easton, in the county of Northampton and State of Pennsylvania, have invented a new and useful Bag-Cleaning Machine, of which the following is a specification.

This invention relates to bag cleaning machines.

The object of the invention is to provide a machine of this character which shall be simple in construction, and thoroughly efficient in a rapid and expeditious manner to remove dust or dirt from fabric bags whereby to prepare them for reuse.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a bag cleaning machine, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts: Figure l is a view in side elevation, partly in section of a bag cleaning machine constructed in accordance with the present invention. Fig. 2 is a front elevation, partly in section, of the machine.

The device embodies a drum supported to rotate upon a frame or base designated generally 1. The drum is constructed, in part, of two spiders 3 and 4, each of which has an outwardly extending tubular hub 5 that is mounted in suitable journal boxes 6 carried by the frame 1. To the arms of each of the spiders are secured two concentrically disposed rings 7 and 8, the former being located at the extremities of the spider arms and the latter at any point adjacent to its center. Secured to the inner sioles of the spiders and rings is wire netting 9 which, as will be obvious, is employed for the purpose of permitting ready escape of the dust removed from the bags. In order to provide a plurality of pockets for the insertion and removal of the bags, the screen is cut away at spaced intervals in its periphery, the material removed being V- shaped, and the edges of the pocket members 10 thus provided are reinforced by me tallic bars 11 and 12 which are riveted to the rings 7 and 8 while the inner ends of the pockets open radially toward the axis and communicate with the interior of the drum. The mouth of each pocket at its Specification of Letters Patent.

outer end is closed by a door 13 that is secured by hinges 14 to the bars 11, and is held closed by a suitable catch or latch 15. As will be noted by reference to Fig. 2, the periphery of the drum is also screened except over said doors 13 so that dust removed from the bags will be certain to escape.

Extending loosely through the hubs 5 of the spiders is a shaft 16 to which is secured a winged beater 17 of any preferred construction, and made of any material best suited to the purpose. Motion is imparted to the shaft 16 and thence to the beater by a gear 18 fast on one of the hubs that meshes with a pinion 19 on a shaft 20, upon which is also keyed a gear 21 that meshes with a pinion 22 on the shaft 16, and by this arrangement it will be seen that the beater is rotated in the same direction as the drum but at a higher rate of speed.-

In the operation of the machine the doors 13 of the various pockets are opened and the dust laden bags fed into the cylinder. As the latter revolves the pockets pick up the bags at the bottom and carry them upward on the ascending side of the drum and drop them upon the heaters which toss them about within the drum and forward in the direction of rotation and operate to dislodge the dust, or loosen any adhering matter, such as cement, and this will escape through the sides and ends of the cylinder. At the conclusion of the operation, the doors of the various pockets are opened and the bags removed. These movements of parts carry the bags slowly up the ascending side of the drum within the pockets, and when any one of the latter has reached a point sufliciently high to dislodge its contents the bags therein fall out and droa onto the more rapidly moving beater. If they fall onto the ascending side of the beater they are simply tossed, but if the drum is moving rapidly enough to cause the bags to fall onto the beater at a point beyond its exact top they are both tossed and thrown forward and therefore instead of falling back on the heater to be tossed again they fall into pockets on the descending side of the drum, around which they proceed again for repetition of the operation just described. 1 have found this motion to be extremely effective for cleaning bags.

From the foregoing description it will be seen that while the improvements set forth are simple in character, they will be thoroughly effective in securing the object sought, and will combine in the presentation ofa practical and highly useful machine.

hat is claimed is:

1. A bag cleaning machine comprising a foralninous cylinder including a plurality of peripherally arranged pockets whose inner ends communicate with the interior of the cylinder, a beater mounted within the cylinder, and connections between the beater and the cylinders for causing them to rotate simultaneously in the same direction but at different rates of speed.

2. A bag cleaning machine comprisinga foraminous cylinder including a plurality of ends communicate with the interior of the cylinder, a door closing the outer end of each pocket, a heater mounted concentrically within the cylinder and having the outer 20 extremities of its blades spaced from the inner ends of said pockets, and connections between the beater and cylinder for causing them to rotate simultaneously and in the same direction and the beater at a higher 25 NORMAN E.
