LOOSE-LEAF ASSEMBLY.

Application filed-January 29, 1927. Serial No. 164,408.

rlhis invention relates to loose-leaf assemblies; especially to the class, such as pads, in which it is desired to remove the sheets with a minimum of etliort, and the main object and feature ofthe invention is the production of a loose-leaf assembly in which no adjustment is necessary to remove the sheets and which automatically adapts itself to a lessening number of sheets.

In the accompanying drawings the inven tion is shown in a concrete and preferred form in which:

F ig. l is a top plan view of a loose leaf assembly embodying a preferred form of the invention.

Fig. 2 is a fragmentary View similar to F ig. l with the post guard screws and top plate removed.

Fig. 3 is a sectional view substantially on the line 3--3 of Fig. 1.

l indicates a suitablek backing member from the face of which extends a plurality of posts 2 here two in number. 3 is a pack of sheets of flexible material such as paper, each of which is provided with a number of perforations 4 and 5, here two in number. The perforation marked liits one of the posts fairly snugly but the perforation 5 is somewhat larger than the post it engages. The object ofthis feature is that it keeps the pack of sheets nicely a-lined without positively clamping them and withal allows said sheets to be readily introduced over the posts from the top thereof, for it will be noted, that although slots 6 are cut in the paper these slots are not for the purpose of permitting the sheets to be introduced endwise over the posts but are merely for the purpose of facilitating their removal from the posts.

7 indicates a loose weight of smaller area than the sheets and this weight slides loosely on the posts so that, as the sheets are removed, it moves downward and tends to keep the sheets in position and also gives a finished appearance to the assembly. Said weight is preferably provided with perfoi-ations 8 and 9, the former fitting one of the posts fairly snugly and the latter being somewhat larger than the other post which it engages. l0 indicates screws, threaded into the upper ends of the posts and having heads larger in diameter than the posts, but these screws really perform no function eX- cept to act as stops against the weight when the assembly is full.

The sheets may be removed as may be desired by simply pulling them out from engagement with the posts without loosening of the screws and by the arrangement shown the pack will not be disturbed but Will be kept nested in position, the weight moving down as theshcets are removed; lf desired, the sheets may be torn along edge 11 of the weight.

To replenish the pad, the screws and the weight are removed and the paper is introduced over the top of the posts, after which the weight and screws are replaced.

I claim:

A loose leaf assembly including: a backing member, two posts extending from the face thereof, a pack of sheets, resting on said backing member, having two perforations, one of which engages one of the posts snugly and the other of which is somewhat larger than the other post it engages, and a loose weight/,of lesser area than the sheets, having two perforations one'of which engages one of the posts snugly and the other of which is somewhat larger than the othel` post which it engages.

Signed at the borough of Manhattan, city, county and State of New York, this 19 day of January, 1927.
