LOOSE LEAF BINDER.

WILLIAM M. WHEILDON, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO LIBRARY BUREAU, OF BOSTON, MASSACHUSETTS, A CORPORATION OF NEW JERSEY.
LOOSE-LEAF BINDER.
Specification of Letters Patent.
Patented July 14, 1908.
To all whom it may concern:
Be it known that I, WILLIAM M. WHEIL- DON, a citizen of the United States, and resident of Boston, in the county of Suffolk and- State of Massachusetts, have invented new and useful Improvements in Loose Leaf Binders, of which the following is a specification. I
My invention relates to binders or files for loose tain improvements whereby the structure and mode of operation of the leaf holdin parts from the binder or file are simplified and facilitated.
In the drawings hereto annexed which illustrate embodiments of my invention, Figure 1 is an end view of an improved binder or file. Fig. 2 is a view on an enlarged scale of a portion of the operative arts.-
In binders or files for loose eaves, it is desirable to have the two. clamping members between which the leaves are secured, held firmly in place under all normal conditions, but on the other hand, that they should be very easily and uickly disengaged when leaves are to be added to or taken from those in the files.
In Fig. 1 there is shown an end view of a binder or file consisting of two binder boards A and B to one of which, inthis case B, the posts C are secured. The other binder board A is perforated (as at A Fi 2) so that it may be slid up and down on tie posts C. The leaves L are clamped and held between the boards A and B. The catch or holding mechanism which holds the sliding board A in position upon the posts C consists of a detent D formed of a single resilient strip of metal which is secured at its two ends to the board A by rivets d normally lies flat against the board and is rovided at the middle with a suitable fingerli being movable toward and from the board A by reason of the resiliency of the plate or strip D. The flexibility of this strip or plate of metal permits the detent to bind upon the fastenmgs d as if upon flexible hinges, and may therefore be considered practically as pivoted or hinged to the art A. Referring to Fig. 2 which shows t e detent D on a leaves and papers and consists in cerold d, the said portion d larger scale the'spring plate is bent upward from the board A at d and then downward toward its middle portion which comprises the finger hold d*.. In this downwardly'inclined position, that is to say the portion which is inclined toward the board A and middle portion, there are provided the perforations d which are slightly larger than the cross section of the posts (J and which by reason of the inclination of the plate normally stand with the edges of the perforations bearing againstthe posts 0 as at d and d". If it be desired to lift the board A, all that is necessary is to place the finger under the finger hold a? of the detent D and lift it to or toward the position shown in dotted lines in Fig. 2, thus releasing the posts 0 from the grip of the opposed edges of the perforations at d and d". This lifting movement then carries the board A upward to any desired position on the posts O or enables the user to remove the board from the posts. In replacing the board A all that is necessary is to press own upon the board itself, the detent D slipping freely over the posts C during the downward movement. Thus,wl1en the leaves L (Fig. 1) are properly compressed between the binder boards A and B their elasticity will tend to throw the board A upward but the gripping edges (i d of the perforations d prevent any movement of the board A in response to the expansive pressure from the leaves L.
What I claim and desire to secure by Letters Patent is:
The combination of posts, a binder board to slide on the osts, a detent consisting of a single flexible p ate secured at its ends to the binder board outside the posts, an'd having inclined portions wherein are perforations to admit and engage the posts, and means to lift the middle portion of the detent to release the grip of the detent on the osts.
Signed by-me at Boston, assachusetts, this 19th day of March, 1907.
WILLIAM M. WHEILDON.
