PATENT CFFICE.

PHILIPP NICHOLS, OF TROY, NEW YORK.

IMPROVEMENTV IN ARM-REVOLVING SHELVES.

Specification forming part of Letters Patent No. 117,103, dated July 18, 1871.

To all whom 'it may concern:

Be it known that 1, PHILIPP NICHOLS, of the city of Troy, in the coiuity of Rensselaer and State of New York, have invented Arm-Revolving SupportShelves, of which the followingis a specification My invention relates to a device by which, for convenience or use, a shelf' or shelves may be readily adjusted to column, pipe, or post, and removed, as occasion may require, without injury to the vertical support, while, by means of the revolving or friction-bearing arms, the relative position of the shelves may be changed, the shelves held firmly near to or remote from each other so as to give a greater or lesser shelf-surface, as occasion may require, and, as constructed and arranged, in operation greatly subserves economy in space, and, with comparatively little expense, prove of varied application.

Figurel is a horizontal view of my device.

Fig. L). is a vertical sectional view of the same,

showing particularly the openings in which the connecting-bolts pass in securing the arms to the collar. Fig. 3 is perspective view of the device secured to a post or pipe with a pendent hook attached to the shelf. Fig. 4 is a horizontal view similar to Fig. 1, showing diiferent forms of shelf.

Fig. 5 is a perspective view of the collar, showing it open. Fig. 6 is a view perspective of the same closed and in reversed position. A is the collar, Ywhich is joined by mutuallysupporting hinge or joint at C. At O is shown the point of contact of the spurs or lips of the collar. Al A are flanges extendingoutwardly from the collar sufficiently far to support the inner extremity of the arm. B is the arm, which is secured by a bolt to the ilange A. B B are shelves on the outer extremities of the lateral arms. D represents a pillar, post, or pipe, around which the collar of the device is clasped; h, a hook pendent from the shelf. The device may be made of wood, with iron nuts and bolts for fastenings, though I prefer to make the different parts of the device of iron or other metal, with sufcient thickness, width, and strength to sufce for its different applications.

The collar A should be made of such width and thickness as the particular use may require, and of such form as to be readily and rmly clasped to its vertical support. The inner eX- tremity of the arm B is rounded, so that, when 1' turned from side to side, it may press strongly against the outer circumference of the collar, and a bolt in the opening made in the ila-nge A, and through the arm above, holds same firmly in position. At C and O the corresponding extremities mutually support each other.

In operation the collar is opened by unscrewing the nut at Gf. The collar is then clasped around the pillar or pipe-support at any required height, and the arms are moved near to or remote from each other, as greater or lesser shelfsurfacc is needed.

The shelves may be of any required shape, diii'erent forms of which are shown in Fig. 4, also different positions of the shelves are indicated in Figs. 1 and 4 by heavy and dotted lines.

As will be seen, the device may be readily clasped upon pillars in warehouse to sustain or show goods in the center of room or away from the sides; upon stove-pipes to hold and warm vessels; upon posts around dwellings for domestic purposes, and for various uses as the eXigency may require. The relative positions of the shelves may be changed, while hooks pendent from the same may be drawn together or thrust apart, as the case may require, in suspending clothing or other anticles thereon; and the device in its varied uses subserves greater economy and convenience in space, more ready capability of changing shelf-surface, and less expense in adaptation to its varied applications than shelves heretofore used.

I claim- The combination and arrangement of two or more rotating or revolving shelf-arms upon the same plane, and resting upon and supported by corresponding flanged supports A A A cast or constructed with the pipe-collar lor clasp, when arranged as described and set forth.

PHILIBP NICHOLS.
