JAMES o. DAWSON, or sr. LOUIs, MIssoURI, ASSIGNOR TO'SIEBER &. TRUSSELL MANUFAC- TUBING COMPANY, A CORPORATION OF'MIssouRI.
Loose-LEA BINDER.
Specification of Letters Patent.
Patented July 14, 1908.
To allwhom it may concern:
Be it known that I, JAMEsO. DAWSON, a citizen of the United States, and resident of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Loose-Leaf Binders, of which the following is a specification and which are illustrated in the accompanying drawings, forming a part thereof.
The invention relates to loose leaf binders and articularly to such binders wherein a plura ity of filing rods are provided for re-v ceiving the sheets to be bound and in which the covers of the binder are preferably structurally independent of each other, one ofsuch filing rods are permanently mountedadjacent its rear or binding edge. and the other cover being a follower for running on the rods.
The object of theinventionis to provide im roved means for removably securing the fol ower of such binders in any adjusted position upon the filing rods and the invention contemplates a filing rod, a follower runningon the rod and a lever pivotally mounted on the follower and having a yielding cam face for engaging the rod. In the accom anying drawings:-Figure 1 is a detail side e evation of'a loose leaf binder embodying the features of the. invention, some of the arts being shown in section and the plane of the section being indicated by the line 11 on Fig. 2; Fig. 2 is a detail plan view of the same "some of the partsbeing broken away Fig. 3 is a detail sectional view taken on the line 33 of Fig. 1; and Fig. 4 shows ir plan a cam lever employed in the device separated from the other parts.
The covers of the binders are designated by the numerals 10 and 11. Preferably each is made flexible along a line extending com:
letely across its surface a short distance fiom ts rear marginal edge as indicated at 12 to permit of the swinging of the bod portions of the covers for inspection of the caves of thebinder. As shown each of the covers is overturned at its rear edge to provide overthe back of the binder.
Filing rods, 15, 16, which may be as numerous as the size of the leaves to. be bound requires, two such being shown, have their bases firmly secured to one of the cover members as 10, adjacent its rear edge preferably by being riveted thereto as indicated at 17.
for carrying each of the levers 2 2.
In order that the length of the filing rods 15, 16, may be adapted to the number of sheets required to be bound these rods are most conveniently made sectional, the outer end of each section being provided with a threaded socket 18, for removably receiving the reduced and threaded inner end, 19, of each succeeding section as 20.
I The leaves X to be bound and the cover member 11, are provided with apertures v 21,- for receiving the filing rods, 15, 16, and
means are provided for securing the cover member 11 In position upon the rods 15, 16, above the leavesin order that the latter may be firmly clampedin position upon the filing rods between thetwo cover members. this end a cam lever 22, is pivotally mounted: upon the cover member 11, adjacent each of the apertures 21 provided for receivin the filing rods, for engaging these rods. A caring plate 23: permanently secured to the cover member 11, as by rivets 24;, 25,'serves As shown plate is overturned upon plate to provide asupport elow the lever'2'2 for the a portion, 26, of this the body of the both above and ivot 27 of the lever and a protective housing or one end of the lever, the body portion and, the overturned portion 26, of the plate being both apertured in line with the aperture 21 of the cover member for receiving the filing rod.
- A thumb piece 28 is formed upon one end of'each of the levers 22 and at the other end a yielding cam finger, 29, is provided for engaging one ofthe filing rods, preferably by notching the lever at 30, as most clearly shown in Fi 4 of the drawings. Preferably the open on of the notch 30, is remote from that part of the cam finger 29, which first '95 engages withthe filing rod in order that the cam finger may 'be more yielding at that ppint where the greatest pressure is applied.
hen constructed in this way no ermanent set will be given to the cam finger even .though it be caused to bind upon the filing rod with great force. Most conveniently the levers, 22, are of such a form and are so mounted upon the cover member 11, that they extend in a direction substantially in line with the binding edge of the book when they are caused to engage with the filing rods 15, 16, and they are thus out of the way I whcnthe covers of the binder are thrown back for an inspection of its leaves. To prevent the desk of the user from being marred by the filing rods 15, 16, the protruding end of each of these rods is covered by a rubber,
ment of the leaves X may then be made and the leaves be again firmly clamped between the covers by the a lication of the cover member 11 to the 1ng rods immediately above the last sheet inserted and by a swin ing of the levers 22 to engage the filing rods for firmly securing the cover member 11 in position thereon.
I claim as my invention 1. In a loose leaf binder in c'ombination, a base, a filing rod rising from the base, a follower running on the rod, and a cam lever pivotally mounted on the follower to bearon the rod, such lever being channeled to permit of a yielding of the cam. I
2. In combination, a filing rod, a follower running on the rod, and a lever pivoted to the contact face and extending substantially parallel thereto, and the 0 en end of the notch being remote from tie point of the initial engagement between the contact face of the lever and the rod.
4. In a loose leaf binder, in combination, a base, a filing rod rising from the base, a follower running on the rod, and a cam lever pivotally mounted on the follower and havmg a yielding engagement with the. rod.
