UNETED STATES ARTHUR R. SELDEN, OF ROCHESTER, NEW YORK.

LOOSE-LEAF BINDER.

Application filed October 31, 1921. Serial No. 511,864.

To all whom it may concern:

Be it known that I, ARTHUR R. SELnnN, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Loose- Leaf Binders, of which the following is a specification.

The present invention relates to loose leaf binders and more particularly to the type employing impaling projections passing through the sheets or leaves to be held. An object of this invention is to provide an impaling projection which may readily be made of different lengths. Another object of this invention is to provide an impaling projection formed of two section connected by screw threads, one of which is rigidly connected to a binding member and the other of which turns on the rigidly secured one. Still another object of the invention is to provide an adjustable impaling projection which will maintain its effective condition of uniform diameter, so that for any extension its diameter throughout will correspond with the openingsinthe leaves. A further object of the invention is to so house the operative parts that they will not be visible, while yet maintaining a compact structure.

To these and other ends the invention consists of certain parts and combinations of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings:

Fig. 1 is a plan view of the rear end of the binder with one half shown in sectio on the line 11, Fig. 2;.

Fig. 2 shows in elevation the rear end of the binder with one'half shown in. section on the line 22, Fig. 1;

Fig. 3 is a sectional view through the ear edge of the binder on the line 3-3,

Fig.1 is a sectional view of one of the impaling pins in the direction of its length;

Fig. 5 is a detail view showing the mannor in which the impaling pins are adjustable; and

Fig. 6 shows one of the impaling pins in elevation. I

In the illustrated embodiment of the invention the binder comprises two members each formed of a cover 1 connected by a flexible or hinging portion 2 with a binding member. Each binding member, in this instance, embodies a flat tube or hollow member 3 and two impaling pins or posts, the

impaling posts preferably being supported from tubular inserts 3, fitting in the tube 3. v In this instance, each impaling projection is composed of an end member 1 having a screw-threaded projection 5, one or more intermediate members 6, each having a screw-threaded soc-ket- 7 for receiving the screw-threaded projection 5 and having a Screw-threaded projection 8 for interlocking with another section. In addition to one or more intermediate sections 6, the post may embody a section 9 which, in this instance, is of tubular formation and has threaded portions 10 and 11 respectively, one for engaging a threaded projection on another section and the other for engaging a threaded section 12 which projects from an inner wall of the hollow member 3 through an opening 13 in the opposite wall. It is apparent that with this invention the impaling pins or posts may be made of different lengths by adding or eliminating sections 6, and it is also apparent that the length may be varied by adjusting the section 9 on the threaded section or projection 12.

With the end in view of holding the section 9 in difl'ere'nt adjusted positions on the screw threaded section 12, the section 9 may be provided with a longitudinally eX- tending groove or slot 1 1 and a locking device may be provided preferably within the tube 3. In this instance, this locking device is in the form of a lever 15 pivoted at 16 to the insert 3 and having a nose 17 adapted to enter the slot 141, as shown in Figs. 1, 4 and 5. A spring 18 acts on this lever normally to hold the latter toward locking position. One end of the lever extends into slots 19 formed in the tube 3 and insert 3 so that such lever may be pressed out of locking position against the action of its spring 18. A series of indications or marks 20 may be provided on the member 9 to indicate the adjustment of the impaling pin or post.

The posts on one of the binding members are situated nearer together than those on the otherbinding member, and these two posts operate through openings 21 in the leaves 22. The posts which are farther re- 110 moved operate through openings 23 in the leaves. This arrangement permits both of the binding members to support the leaves in proper relation for cooperation with theimpaling posts or projections of the other member.

For the purpose of loclzi'ng the binding members together means is provided on oneof the binding members for cooperation with the impaling posts or projections of the other binding member. In this instance, two locking devices are provided on the-binding I member that icarries the posts passing through the openings 21 of the leaves. These locking devices, in this mstance, each embody a lever 24 mounted'to turn on a pin 25, which i's'supported by two ears 26 struck up from the insert-tube 3. one end 27 formed with an openingadapted to receive one of the ianpaling pins or posts, in order that the walls of the openings may clutch or grip the postto prevent the'latter being withdrawn from the binding member carrying the locking device. A spring 28 acts on this clutch lever to 'hold' it inclutclr ing position. The clutch lever also has an end- 29 disposed adjacent alined openings 30 in the- tubes 3 and 3 so that pressure may be received from 'a finger passed through such openings.

simultaneously and thispermits the two b1nd1ng members to be separated. The cloth 31, whichcovers thebinding members except at their ends which are-closed by caps 31 also covers the openings 19 and 30,

so that while the levers 15 and 25 may be operated from the exterior of the binding members, the operating ends ot'suclr levers are invisible.

The impahng' posts or pro ections are made of lengths to correspond to the number of leaves held between'the binding members, this result being secured by eliminat- .ing the sections 6 of the post orby-adding as "many of such 'sectionsas desired and, at the 1 same time, ad usting the sections 9 on the screw section 12. Owing to'th-e fact that the screw-thremfled inner sections of the impaliug' posts pro ect from the inner walls of the hollow binding members through openings in opposite walls, the posts for any adjustment throughout their effective lengths and corremaintain a unittorm diameter spond with the diameter of the openings in the leaves. The twobmdmgmembers are This lever has In orderto release the binder, both of the clutch levers must be operated fitted together and the locking clutches automatically slide over the posts or projections which pass through the openings 23 in.

the leaves, and establish a clutching relation with said posts or projections and prevent the separation of the binding member until the finger portions 29 of the clutching members are depressed when the posts are freed and the binding members may be separated.

What I claim as my invention and desire to secureby Letters Patent is:

-1. A-loose leaf binder embodying an impaling post or projection comprising two provided with a longitudinally extending notch, and a locking device cooperating with the walls of the notch to hold the section againstturning, a spring acting on said locking device to maintain 1t normally toward locking position.

3. Aloose leaf binder comprising a tubular bindingme'mber having an opening in one wall, an impaling pin or projection embodying twosections one of which is in the 'form of a screw-threaded projection extending-from an inner wall of the tubular binding-member through the opening and the other of which turns in said opening on said screw-threaded "projection, a locking device for said second-mentioned sectlon arranged within said tubular binding member and. having a portion operable from the exterior of said binding member.

4. A loose leaf binder comprising a hollow binding member provided with an opening in one wall, an externally threaded post section secured to an inner wall of said binding member, and extending through "aid opening, and an internally threaded post section adjustable in said opening on the firstnamed post section.
