The nature of our invention is that we have attached the clip and spring which closes the clip to an outer cylinder which works over an inner cylinder by means of a screw thus enabling the clip to be raised or lowered so as to accommodate a larger or smaller quantity of paper.

E is a hinge by which the clip is attached to the outer cylinder; C, the spring attached to the outer cylinder which shuts the clip.

Fig. 3 is a vertical Section showing wherein our clip diers from all other clips now in use.

We construct a cylinder, at theJ upper end ofwhich we place the nut i through which the extension screw Z) works, the bottom of the cylinder being attached to the board in any convenient way.

f is the outer cylinder which is made to slide over the inner cylinder by means of the screw b, thus enabling the clip to be raised or lowered to accommodate a larger or smaller quantity of paper. i
