JOHN T. DRINK AND EDWARD NORDSTROM, OF TOPEKA, KANSAS.

LOOSE-LEAF BINDER.

Application filed January 19, 1912.

10 all whom lz? may concern:

Be it known that we, JOHN T. BRINK and EDWARD NORDSTROM, both citizens of the United States, and residents of Topeka, in the county of Shawnee and State of Kansas, have invented a new and Improved Loose- Leaf Binder, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved form of loose leaf binder constructed so as to be of substantially unlimited capacity, and capable of quick and easy opening and closing for inserting or removing leaves.

A further object of the invention is the provision of an improved structure which when assembled includes a plurality of rigidly positioned posts for holding leaves in position, associated with means for instantly causing an extension of the binder after which a leaf may be inserted or removed and the binder again contracted or reassembled.

A still further object of the invention is to provide an expansible loose leaf binder constructed with telescoping posts, one of which being formed as a binding post, in which the inner members thereof may be clamped to the outer member at any desired points of relative longitudinal adjustment between the inner and outer members.

In carrying out the objects of the invention, any desired form of back may be used, to which are connected a front and back metallic housing carrying a plurality of post-s, one of which acts as a locking post. The locking post is associated with locking means extending to one end of one of the metallic housings so that the posts may be properly locked and unlocked quickly from one side ofthe binder. Arranged in the housing opposite the locking means are a plurality of devices for engaging and holding posts rigidly in position, these devices being adapted to be disconnected from the posts whenever desired, either for permitting the addition of auxiliary posts, or

.merely for the purpose of inspection.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

through Fig. 1 on line 2 2; Fig. 3 is a sect-ion through Fig. 1, approximately' on the line 3 3; Fig. 4 is a section through Fig. 1 approximately on the line 4-4, the locking member being shown in an open or unlocked position; Fig. 5 is an enlarged detail perspective view of the locking nut; Fig. 6 is a perspective view of the locking sleeve; Fig. 7 is a perspective view of the locking bolt; and Fig. S is a side view with certain parts broken away, disclosing an auxiliary or extension post.

Referring to the accompanying drawings by numerals, 1 indicates part of the upper cover and 2 part of the lower cover. The upper cover is formed with a housing or binding plate 3, having a covering lid 4 connected therewith in any suitable manner, as for instance, by rivets 5. The cover 2 is formed with a housing or binding plate 6, provided with a cover 7 held in place by bars 8, 9, and 10, each of which is preferably formed rectangular in order to engage the locking nuts 11, 12, and 13, respectively. The locking nuts 11, 12, and 13, are each divided into half and formed with a wedgeshaped opening 14 designed to receive a V-shaped projection 15 extending from the reciprocatiiig plate 16. Each of the nuts 11, 12, and 13 are beveled on two of their faces so that the nuts will be substantially wedgeshaped for fitting against the bevel walls of openings 17, 18, and 19 formed in the plate 16. The plate 16 is formed with an arm 20 having a lug 21 projecting therefrom for normally engaging the end of the 'housing 6 for preventing any longitudinal movement of the plate 16 in one direction. A hand-operated member 22 is provided on the end of the arm 20 which is positioned on the exterior of the housing 6 so that the same may be grasped and pushed downward until the lug or catch 21 is disengaged. This movement is permitted by the spring of the arm 20 so that the arm 20 and the lug or catch 21 may be pulled out through an opening 23 until the plate 16 is moved a suiiicient distance for opening all of the nuts 11, 12, and 13. In Fig. 4 the nut 13 is shown in open position, from which it will be observed that the threads of the nut are disengaged from the post 24. The respective nuts 11, 12, 13, engage the respective posts 24, 25, and 26, the post 25 being the locking post.

Telescoping over the posts 26 and 24 are tubular posts 27 and 2S secured to the housing 3 by a suitable thread and arranged to project into the housing 3 for a considerable distance, preferably to near the top of the housing. Each of the posts 27 and 23 is formed with a shoulder 29 for cri-acting with shoulders 30 and 31 formed on the posts 26 and 24 in order to prevent the removal of posts 26 and 24 from the tubular posts 27 and 28 when the binder is expanded. Incidentally this will prevent the locking post 25 from becoming disengaged with the locking sleeve 32 and the locking bolt 33. rThe locking sleeve 32 is secured to the housing 3 by threads or other desired means, and is formed with a plurality of slots 34 for permitting an enlargement 35 of the bolt- 33 to expand the same and press against the walls of the tubular post 25. This will lock the posts 26 and 24 and their :respective tubular surrounding posts 27 and 28, in any adjusted position, and also permit the locking and unlocking of the binder for the insertion and removal of the leaves.

The locking post 33 is threaded at 36 for receiving a locking nut 37 formed with a pair of cam faces 38 and 39, and a central projection 40. The central projection 40 is arranged to project through a slot 41 in a locking plate 42, and the cam faces 38 and 39 are adapted to press against the upper surface of the cam member 43 projecting from the locking plate 42. The cam member 43 is arranged to extend at an angle to the general direction of the housing 3 so that a longitudinal movement of the same will cause a transverse movement of the locking nut 37 and locking bolt 33. The locking plate 42 is provided with an aperture 44 for accommodating the tubular sleeve 27 and one of the rivets 5. The plate 42 is also formed with an arm 45 adapted to be suiiiciently resilient for permitting the offset 46 to pass out opening 47 when the hand-operated Vmember 4S is moving longitudinally away from the housing 3. It will be evident that the longitudinal movement of the locking plate 42 in one direction will cause the locking bolt 33 to lock ,the post against longitudinal movement and the moving of the locking plate 42 in an opposite direction will permit a free movement of the posts under the action of springs 49 and 50 mounted in sockets formed in the posts 26 and 24. From this construction and arrangement it will be evident that upon an outward movement of the hand-operated member 48 the binder will be unlocked and will be substantially instantly expanded by the springs 49 and 50, these springs being normally under tension. rThe leaves then may be inserted if the same are of the variety having slots therein which will accommodate thel respective posts. However, if leaves having only holes or apertures therein are used the plate 16 must be moved longitudinally for disconnecting` the housing from the posts 24, 25 and 26. After the back 2 has been removed, to which the housing 6 is secured, the leaves may be placed in position and then the back again connected with the respective posts, after which the binder may be closed by pressing the back and cover together until the leaves are clamped properly, and then operating the locking plate 42 for causing the locking bar 43, by means of the locking post 33, to clamp the sleeve 32 against the post 25.

The respective posts may be made of any desired length, but the extension of the binder upon the releasing of the lock will be slightly less than the length of the respective posts. This extension is quickly accomplished, and is designed to permit the quick insertion and removal of leaves up to the ordinary limit of the binder. l/Vhen it is found that the binder is expanded to substantially its full limit, additional or auxiliary posts 51 are screwed on to the posts 24, 25, 26, these auxiliary posts being threaded at 52 for fitting over the threaded ends of the respective posts. The auxiliary posts 51 are threaded at 53 for receiving the nuts 11, 12 and 13. The auxiliary posts 51 may be made of any desired length, but are preferably made comparatively short so that the enlargement of the binder will be such as to allow the usual action of the various parts. It will be evident that any desired number of auxiliary posts 51 may be added so that the binder is unlimited as to its capacity for receiving leaves.

By providing means for quickly expanding the binder and also by providing means for enlarging the binder, the insertion or removal of leaves is facilitated and a binder having unlimited capacity is provided. Notwithstanding these advantages the arrangement of the posts as described, gives a rigidity and strength to the binder found in the permanently secured posts.

Having thus described our invention, we claim as new and desire to secure by Letters Patent:

1. 1n a loose leaf binder, a front plate, a back plate, said back plate being formed as a housing, a plurality of impaling posts rigidly connected to said front plate, each of said impaling posts extending into said back plate, and the posts extending into said back plate being formed with grip-engaging means, grips arranged in said back formed into a plurality of parts, and a reciprocating cam member engaging the parts of each of said grips for causing the same to engage the gripping engaging means of said im' paling posts.

2.
