constitutes a convenient and adjustably positioned projection from which various articles may be suspended. The hook may be the latter which is exposed'between the upper and lower flangesof the rail, but is preferably connected near the lower'end 18 at-a point just abovethe edge of the lower flange 13, whereby to increase the stability of the block when the hook is supporting a load and decrease the pressureapplied to the upper flange 12 by'the upper end of the block.

A supporting device embodying the structural: features-above described is extremely inexpensive to manufacture, since no notches or special formations of any kind need be provided at intervals in the railto permit application or removal of the article-supporting members, and the rail is consequently of uniform cross-sectional shape throughout the length thereof. Furthermore, the article-supporting members do not have to be applied to or removed from the rail at certain locations only, but may be applied 'or removed'at any point.

If desired, the bottom 21 of the rail, and the lower end '18 of the block 16, may be corrugated, as shown in Figs' 2, 3 and 4, in order to prevent the block fromj shiftin longitudinally of the channel when the'hook is supporting a load and the force applied thereto is not strictly in a plane perpendicular to the rail. The corrugations, being nonlnterlocklng in a direction lengthwise of the .rail, as best shown in Figs. 2 and 5, will yieldingly resist :sliding movement of the block 16 to an extent suflicient to preventac-,

cidental displacement of thesame, but such corrugations do not make it necessary for the block to be first lifted in order to change the posi'tion'of the same. I

In Figs. 6 to 9 inclusive ofthe drawings is illustrated another'structural embodiment of the inventionwhich differs from the form first described inthe following particulars:

her is securely looked in By employing the cooperating flange and groove construction described, no change in the uniform appearance of the rail is effected as the rail is 'usuallyplaced above the level of the eye, and the article-supporting memnel of the rail.

In Figs. 10 and 11 isillustratedstill another embodiment of the invention which differs from the first'form in that the corruposition in the changations between the block and the bottom of the channel are omitted and the block 16v is provided on the upper facethereof with'a light bow spring 28, which bears resiliently at all times against the top 29 of the rail 10 and tends to prevent the block from shifting or tilting when in use. The spring-28 is caused toflatten against the top of theblock 16 when the latter is removed from the rail.

In testimony whereof I have hereunto subscribed my name.
