2 Claims.

, `The `present inventio-n relates to means for placing `bags over garments and the like, and has for its object to provide a device wherein `automatic actuating means are controllable by the .operator, increasing the facility and speed of operationwwith respect Ito manually operated means ordinarily employed.

Among v,the lfeatures of invention, in addition to the `mainioperating mechanism, are means for opening the bag to receive article to be covered.

These and other features of the invention will be more specically Set forthin the following description and the accompanying drawings, wherein: Y

Figure 1 is a view in front elevation of the invention, showing in solid lines the parts in position with a supported bag placed over a garthe garment Vor, other `ment, and illustrating in dotted lines the parts with the bag in raised position.

Figure 2 is a view in side elevation of the device.

Figure 3 is a view illustrating means for spreading the bag in operation of the device.

Figure 4 is a sectional view of an air-controlled mechanism forming part of the invention; and

Figure 5 is a view in front elevation of the invention embodying a modified form ofsupporting framework. Y

Referring to the drawings in detail, in the construction shown in Figures 1 yand 2, A represents a bracket adapted to be supported from a ceiling.

` `Depending from the bracket is a rod 2, the lower end of which rod supports a hook 3 adapted to receive the hook 4 of a garment hanger 5 designed to support a garment t, the plate S-a preventing `the garment hanger 5 from turning out of alinement.

For the purpose of placing a bag over the garment 6 the following mechanismis employed:

Slidable upon the rod 2 is a collar member l. Supported by the collar member is a clip S to'support a bag 9. The bag 9 is of usual construction wherein the closed end of the bag is formed with an opening I to receive the hooked end of the garment hanger when the bag is placed in covering position over the garment. A cable II is connected at its lower end to the collar member l, the cable passing over a sheeve I2 supported by the bracket A, and over sheeves I3, I4, and

` I5, and I--a to the cross-head I6, the cross- `head supporting the sheeves I3 and l5. The cross-head I6 constitutes the outer end of a piston rod I'I. The opposite end of the piston rod supports a piston I 8 vslidableinV a cylinder I9, said cylinder being supported by the bracket A.

(c1. 22e-1s) For the purpose of normally holding the `piston I8 in the indrawn position shown in Figure 1, there is provided a coil spring 29, connected at one end to adjacent head of the cylinder I9, and

at its other end as by the hook 2l to the cross- Z5 head I9 or the sheeve assembly i3 and I5.

A rubber bumper 22V is preferably supported underneath the bracket A to receive the impact of the collar member 7 when said collar is raised in the operation of the device.

For the purpose of actuating the piston i8 there is provided a pipe'23 tapped into the closed end of the cylinder i9'. The pipe 23 is connected to a source of air supply through the valve mechanism shown in Figure 4. The valve casing 24 contains a rotary valve 25 actuatable by a foot lever 26. An air passageway 21 is formed through the valve member, the passageway leading from the inlet 28 and connected with a source of air supply, not shown, past the valve to the pipe 2S. An adjusting needle 29 is threaded in the side of the valve casing and projects into the passageway 2l to permit control of the ilow of compressed air. To assist in the free exhausting of the air from the cylinder i9 a second passageway 30 connects the main passageway above and below the needle 29, said passageway 39 being normally closed by a springV closure 3i.

For the purpose of spreading the bag in the operation of the device there are provided spring fingers 32 depending along the sides of the lower Y rod. When the collar is raised in the operationV .of the device above the spring ngers, the spring lingers will be free to spring outwardly, as shown in Figure 5, to spread the bag.

In the operation of the form shown in Figures 1 to 5, the bag 9 will be supported at one side of the opening I0 in the closed end of the bag by the clip 8. With the parts in the lowered position shown in solid lines in Figure 1, actuation of the valve-controlled lever 2B will turn the valve mechanism into the position shown in Figure 4, allowing compressed air to pass through the pipe 23 and carry the piston I8, with the connecting sheeves and cable, outwardly to therdotted line position shown in Figure 1, raising the bag to the upper end of the rod. 'I'he garment would then be hung upon the lower end of the rod. The foot lever 26 will then be released to stand in the dotted Yline position shown in Figure 4, exhausting the air from the cylinder, and allowing the parts to pass to the solid line position shown in Figure 1, through the action of the coil spring 20. During that period of time that the collar 1 stands in raised position above the expanding springs 32, said springs will expand as shown in Figures 3 and 5, and being inside of the bag 9 will spread the bag to permit the bag to drop over the garment. As the collar member 'I drops into the solid line position shown in Figure l the spread bag will drop over the garment 6 and the springs 32, as the collar 1 drops to the lower end of the rod will be drawn against the rod by the enclosing collar l.

There is not only the great advantage in speed and accuracy of operation over the ordinary apparatus where a depending cable is operated by hand to raise and lower a covering bag, but the necessity for any depending cable hanging down alongside the apparatus, other than the cable that supports the bag, is entirely eliminated, making it very much easier to handle the bag and the article to be supported.

While the apparatus is especially designed for placing a bag over garments it could well be used for placing a cover over other articles, as bunches of bananas, etc.

We claim:

1. A bagging apparatus of the class described,

comprising a suspended standard, a bag carrier slidably supported upon said standard, outwardly expansible spring fingers carried by the lower end of said standard and normally held in alinement therewith by said carrier, a movable element supported at the upper end of said standard, a cable connecting said carrier with said movable element, a source of actuating power for said movable element, and means for drawing said source of power into operative connection with said movable element to raise said carrier through said cable out of engaging position with said expansion fingers, for the purpose set forth.

2. A bagging apparatus of the class described, comprising a suspended standard, a horizontally disposed cylinder positioned above said standard, a common supporting bracket for said cylinder and standard, a horizontally slidable rod axially of said cylinder, a piston supported by said rod within said cylinder, a cable support carried by the outer end of said rod, retractive spring means for said rod and cable support, a cable leading from said cable support downwardly along the standard to the bag carrier, and means for supplying air to and exhausting the same from the cylinder beyond the piston, for the purpose set forth.
