LOOSE-LEAF BINDER.
Patented May 2, 1911.
Application filed August 5, 1910. Serial No. 575,798.
To all whom it may concern:
Be it known that I, EDWIN JAMES PorTIN- GER, bookbinder, a subject of the King of Great Britain, residing at Speranza, 28 Lousanne road, Hornsey, in the county of Middlesex, England, have invented certain new and useful Improvements in Loose-Leaf Binders, of which the following is a specification. I
This invention relates to improvements in loose leaf binders comprising a bottom bar having three uprights and a topbar.
The present invention has for its object to produce a binder of the above kind but of simpler construction and operation than heretofore and less expensive to manufacture, and whereby a better looking action is obtained.
To-this end, the improved binder comprises a base bar having three uprights I which may be grooved at the top, and a top bar or locking bar having a notch at opposite sides near each end and a key hole or other suitably shaped apertures at its center. The groove or the like in the central upright is preferably placed a little higher than the grooves in the outer uprights so that when the central hole of the top bar or looking bar engages the central upright on the basebar the top bar may be turned to bring the notches adjacent to the grooves in the outer uprights and bent or sprung at the ends to engage the outer uprights whereby a secure locking action is obtained.
The invention is illustrated in the accompanying drawings in which Figure 1 is a front elevation of the improved binder device showing the same mounted on one side of a cover for use as a loose leaf ledger. Fig. 2 is a plan view. Fig. 8 is a plan view of the top or looking bar removed. Fig. 4c is an edge view of the top bar. Fig. 5 is an end view of the device and complete cover. Fig. 6 illustrates a modification of the center-upright. Fig. 7 shows a locking bar or top bar for use with the modification shown in Fig. 6, part of the latter being broken away.
A. represents the base bar which is at tached to one of the sides B of the cover, adjacent to where it joins the back 5 by rivets or in any other convenient manner. Rising from the bar A. are three uprights, a preferably all solid, formed with grooves,
at, around their upper parts. The two outer uprights are of the same height but the center upright is a little taller.
C. represents the top bar or looking bar formed with a key hole shaped aperture, 0 at its center, and with notches, 0 at opposite sides at each end. This may be made of steel or other suitable elastic material. The bar 0. is preferably turned up slightly at each end as at 0 to prevent it from catching the leaves to be bound when turned horizontally in the action of locking the bar as hereinafter explained.
The operation of the device is as follows :-The sheets or leaves to be bound together and already provided with suitable holes are threaded upon the uprights of the base plate. The top bar is then engaged by means of its key hole with the groove of the central upright of the base plate so that the narrow part of the upright engages the narrow part of the hole, and is then turned horizontally so that the notches are in proximity to but a little higher than the grooves in the tops of the outer uprights. ing the ends of the top bar down a little and continuing the turning movement, the notches are made to engage the grooves in the outer uprights with a locking action and the leaves are held securely in position until they are to be removed. Filling up pieces may be used if necessary between the top bar and the leaves.
In a modification of the foregoing the center hole, 0 is circular so that upon engaging the hole with the central upright, which in this case is formed wit-h a reduced cylindrical upper end presenting a shoulder for the top bar to rest on, the latter may be turned and its ends depressed so that the notches engage the grooves in the outer uprights, as aforesaid.
Claims.
1. A loose leaf binder comprising a rigid base, three grooved uprights rising therefrom, the grooves in the uprights being located at different levels and a spring bar having an aperture to engage with a groove at one level and other apertures adapted to engage with the other grooves when such bar is bent.
2. In a loose leaf binder a locking bar, consisting of a strip of elastic material having a key hole slot at the center and recessed By then spring at the end combined with uprights adapted to engage with said bar when the latter is bent.
3. In a loose leaf binder the combination consisting of a rigid base, three uprights thereon, the center upright being adapted to hold a locking bar at a slightly higher level than the outer uprights, the outer uprights being fitted with means for engaging the locking bar and a flexible locking bar adapted to pass over the upper end of the center uprights and having recesses which when the'bar is turned around the center upright are brought into juxtaposition with the outer uprights and engage the latter.
4. A loose leaf binder consisting of a base plate provided with uprights grooved at the top and an elastic bar upturned at its ends and adapted to slip upon one of said uprights, to be slightly bent and then to engage with another upright by embracing the grooved portion thereof by means of suitably shaped and conveniently placed openings in such elastic bar.
5-. A loose leaf binder comprising a rigid base, three "grooved uprights rising therefrom, the grooves in the uprights being located at'd ifierent levels and a spring bar with-upturned ends having an aperture to engage with a groove at one level and other apertures adapted to engage with the other grooves when such bar is bent.
6. In a loose leaf binder a locking bar, consisting of a strip of elastic material upturned at its ends having a key hole slot at the center and recessed at the end combined with uprights adapted to engage with said bar when the latter is bent.
7. In a loose leaf binder the combination consisting of a rigid base, three uprights thereon, the center upright being adapted to hold a locking bar at a slightly higher level than the outer uprights, the outer uprights being fitted with means for engaging the locking bar and a flexible locking bar with upturned ends adapted to pass over the upper end of the center upright and having recesses which when the bar is turned around the center upright are brought into juxtaposition with the outer uprights and engage the latter. i
In testimony whereof I have hereunto set my hand in the presence of two witnesses.
