3 Claims. 3 01. 248-328) v r to-be'hu ng'or suspended therefrom. The lower This invention relates to an adjustable suspension device. a I I The object of the present invention is to generally improve and simplify the construction'and operation of suspension devices; to provide a,

suspension device embodying a chain adapted to be hung from a suitable support and. a hanger slidably mounted on the chain and adapted to be secured at any point intermediate the ends thereof, and more specifically stated, to provide a hanger having a tubular shank through which the chain extends and' a slot forming spaced shoulders at the lower end of the shank to releasably engage the links of the chain and thereby permit adjustment and securing of the hanger with relation to the chain at any elevation desired.

The adjustable suspension device is shown by way of illustration in the accompanying drawing, in which- Fig. 1 is a side elevation in a suspension device.

Fig. 2 is an end view showing the rear side of the tubular hanger.

Fig. 3 is a sectional view of the tubular hanger showing the employment of a link chain.

Fig. 4 is a sectional View showing a modified form of the hanger.

Fig. 5 is a front view of the hanger shown in Fig. 4, and I Fig. 6 is a cross section taken on line VI-VI .ofFigJl.

Referring to the drawing in detail, and particularly Figs. 1 and 3, it will be noted that the section showing '35 suspension device comprises in general a chain A and a hanger B carried by the chain and adjustable longitudinally thereon to assume different points of elevation.

Different types of chain may be employed. In Fig. 1 a bead type of chain is shown, and in Fig. 3 a link type of chain. The upper end ofthe chain may terminate in an eye, such as indicated at 3, and may be hung from a hook as shown, or the upper end of the chain may terminate in a hook and as such may be hung from a picture molding, the top edge of a door, or any other suitable convenient support.

The hanger employed in the preferred form comprises a tubular member generally indicated at B. The upper end is open to permit the chain to be passed freely through the tube and is provided with a lip 3a. to slidably engage the chain. The lower end of the hanger is arranged at an angle, as shown at 4, and terminates in a I 55 hook 5 to permit devices of difi'erent character end of the tubular portion ofthe hanger is notched or slotted on its rear-side, as indicated at 6, to form spaced shoulders for the purpose of releasablygripping the individual beads; 1 58:

links forming the chain, thus providing a means for adjusting the hanger longitudinally of the chain and for securing the hanger at any elevation desired.

,In actual operation the chain is hung from 10*.

any suitable support .and its free end passes through the tubular shank of the hanger. The slotted lower end of' the hanger normally engages" with one or the other of the links or beads of the chain and supports the hanger 5 against downward movement. If it is desired to raise orlower-the hanger, it is only necessary to grasp the hanger with one hand and to exert a downward pull on the lower free end of the chain with the other hand. A pull ,20 in this direction pulls the links or beads of the chain out of the slot and by swinging the free end of the chain in the direction of arrow a, see Fig. 1, the chain is kept clear of the slot and the hanger maythus be adjusted up- 25 is further prevented, by bending of the'chain through means of the arcuate form of the hanger. v v

The hanger due to simplicity of construction and operation is quickly released for adjustment and just as quickly engaged, and when its use is not required the upper end of the chain may be unhooked with relation to its support and the chain may be wrapped around the hanger thus forming a compact bundle which may be conveniently packed or stored as conditions may demand.

The device may be used forhanging pictures r and other objects but it is particularly intended U as a support for enema bags, and the like,

such as. indicated at I. A modified form of the hanger is shown inFigs. 4, 5 and 6. In this instance a hook 5a is employed similar tothe hook shown in Figs. 1 and 3, but

in place of a tubular shank a curved plate 8 is employed. This plate is preferably formed A by stamp and die operations and loops or eyes 9 are pressed out of the metal on the rear side to form a guideway for the chain. A lower loop or eye It) is also formed and this is slotted as at H to engage the links or beads of the chain. The loops or eyes 9 perform the same function as the tubular shank of the hanger B and the slot H performs the same function as the slot 6, hence the operation and utility of the device shown in Figs. 4, 5 and 6 are the same. I

While certain features of the present invention are more or less specifically described, I wish it understood that various changes may be resorted to within the scope of the appended claims. Similarly, that the materials and finish of the several parts employed may be such as the manufacturer may decide, or varying con'di tions or uses may demand. Y

Having thus described my invention, what I claim and desire to secure by Letters Patent is -1. A'sus'pension device comprising a chain a'daptedto be hung from a suitable support, a tubular member slidably mounted on the chain, a slotted portion formed in one end of the tube and forming spaced shoulders releasably engageable with the links of the chain to secure the tube at any elevation interme-' diate the ends of the chain, said tube being bent to form an offset in' the chain to retain the chain links againstaccidental release with relation to the shoulders, and a hook on the tube from which objects to be supported may be hung.

2. A suspension device comprising a chain adapted to be hung from a suitable support, a tubular member slidably mounted on the chain and having a link-engaging portion disposed at one end of the tube and releasably engageable with the links of the chain to secure the tube at any elevation intermediate the ends of the chain, said tube being bent intermediate its ends to form an ofiset longitudinally of the chain to retain the chain-engaging member against accidental release with relation to the links of the chain, and a hook on the tube from which objects to be supported may be hung.

3. A suspension device comprising in combination a pendant chain and a rigid hanger adjustably mounted upon the chain, said hanger being substantially arcuate in longitudinal section and comprising a portion at its upper end for slidable engagement with the chain, linkengaging means adjacent the lower portion to releasably engage the links of the chain when moved vdownwardly, and a load-supporting member at the lower end in oflset relation with the link-engaging means, whereby when a load is imposed on' said load-supporting member the hanger will be tilted in a direction to flex the chain and force the link-engaging means into firm engagement with a link of the chain for the purpose of supporting the load in various elevations.
