Application'September 23, 1941 Serial No. 412,020 3 Claims. (01. 129-38) This invention relates to lock binders for magazines and similar publications and the object of the invention is to provide a lock binder which is so constructed that it will be impossible for anyone surreptitiously to remove the magazine or publication from the holder to which it is attached, but from which it can be easily removed by an authorized person having the proper unlocking key therefor.
Another object of the invention is to provide a binder for a magazine or other publication in which the parts are not completely disassembled in order to remove the magazine or other publication therefrom.
Another object of the invention is to provide a lock binder for a magazine or other publication which consists of a few simple parts and therefore may be economically manufactured.
we accomplish the above, and other objects of the invention which will be apparent as the description proceeds, by means of the construction shown in the accompanying drawing, in which Fig. 1 is a perspective of the device constituting our invention, showing the parts in partly disassembled position;
Fig. 2 is a vertical section of the device in assembled position;
Fig. 3 is a horizontal section. through one end of the device; and
Fig. 4 is a perspective of the unlocking key on an enlarged scale.
On the drawing, in which like reference character indicate like parts on all the views thereof,
I indicates the base bar to which is to be secured the binder cover for the magazine or similar publication by means of screws 2.
At each end of the bar I is mounted a casing 3, provided with a central cylindrical opening 4, a portion at least of which is screw threaded, as shown at 5. A longitudinal slot 6 is formed on the inner face of each casing, the slots in the casings being in alignment with and facing each other, and each extending to the cylindrical opening 4 of its respective casing. The slot in one of the casings extends entirely through the casing for a portion of its length, as shown at I.
A clamping bar 8 is provided with notches 9 near each end thereof, the purpose of which will presently appear. The clamping bar 8 isof properwidth to be passed through the" slot 1 and of such length that its ends will rest in the slots. 6 when in itsoperative position.
Screws are provided for positioning in the openings 4, each having a. countersunk recess in its head for engagement by the key shown in Fig. 4. I I
The openings 4-are of smaller diameter at their upper ends than in the main portions thereof so as to provide overhanging walls I l which prevent the screws from being removed through the openings in the upper ends of the casings. To assemble the device, the screws ID are inserted in the openings 4 of the casings through the lower ends and the casings are then welded or otherwise secured to the bar I.
In use, the back of the magazine or other publication is placed on the base bar I between the two casings 3, and the magazine or other publication opened; the clamping bar 8 is then slipped through the slot 1 and over the opened book until the forward end rests in the slot 6 of the opposite casing. Both ends of the clamping bar will then be free to slide up and down in the slots 6 of the two casings. The key is then inserted in the countersunk recess of each of the screws 10 and the screws tightened thereby until they force the clamping bar against the magazine or other publication.
In order to remove the magazine or other publication from the lock binder, it is only necessary to loosen the casing screws sufficiently to permit the clamping bar to be raised until the end adjacent the slot 1 is in line with so that it may be slipped therethrough.- It will be seen that, due to the overhanging shoulders at the tops of the openings 4, the screws cannot be removed from the casings, thereby preventing their possible loss. Moreover, it is to be noted that it is not necessary that the clamping bar be entirely disconnected from the remainder of the device, since it is only necessary to move it to a position where the magazine or other publication can be slipped from beneath the clamping bar.
The notches 9 are provided for the purpose of facilitating the clamping and unclamping operations of the clamping bar 8. When the clamping bar has been positioned between the leaves of the magazine, the key may be positioned in the notch in the upper face of the bar whereupon pressure upon the key will force the bar into position between the leaves of the magazine. When it is desired to remove the magazine after the clamping screws have been loosened, the clamping bar is slid to release it from the left hand casing and the key is engagedin the notch in the lower face of the bar, when an upward pull on the key will pry the bar from its clamping position.
It will thus be seen that we have provided a publications, a base bar, an upright casing at each end thereof, said casings having slots in the inner faces thereof in alignment with each other, the slot in one of said casings extending entirely therethrough, a clamping bar passing through said slots and parallel with the base bar and slidable outwardly through said slot in said one casing, said casings having openings therein, and means in the openings cooperating with the clamping bar for holding the bar in clamped position.
2. In a lock binder for magazines and other publications, a base member, a casing at each end thereof, said casings having longitudinal slots therein in alignment with each other, the slot in one of said casings extending entirely therethrough, a clamping bar resting in said aligned slots and slidable outwardly through said slot in said one casing, said casings having openings therein communicating with said slots, means in said openings for holding the clamping 'bar in clamped position, and means for preventing the removal of said last named means from the openings.
3. In. a lock binder for magazines and other publications, a base member, a casing at each end thereof, each of said casings having a longitudinal screw-threaded opening therein, a longitudinal slot on the inner face of each of said casings and in alignment with each other, a clamping bar resting in said aligned slots, a screw member in each of said openings and operable to bear against said clamping bar, and means in said openings for preventing the removal of the screw members from the openings, said last named means comprising an overhanging Wall at the upper end of each of the openings.
