TEMPORARY BINDER..

SPECIFICATION vforming part of Letters Patent No. 764,413, dated July 5, 1904.

Application 1xilefl August l5, 1903. Serial No. 169,627. (No modelJ To al?, whom, it may concern:

Be it known` that I, ALFRED T. BAXTER, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Temporary Binder, of which the following' is a full, clear, and exact description.

My invention relates to improvements in devices for holding loose leaves or sheets in a secure manner, the same being commonly known y as temporary binders.

The improvement which I have made is directed more particularly to the element known in some classes of binders as the postthat is, the spindle or pin over which the leaves are slipped and on which they are held orconfined usually by a locking-Slat, which is adapted to have interlocking engagement with the post at different points, according to the thickness of the mass of leaves.

The object that I have in view is to provide an improved form of post capable of eXtension or prolongation on the gradual accumulation of the leaves, said post having its members interlocked and held in asecure positive manner and always presenting the ratchetteeth on its several members in position i'or elngagement with bolts or dogs on the lockings at.

Further objects and advantages of the invention will appear in the course of the subjoined description, and the actual scope thereof will be defined by the annexed claims.

VReference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the iigures.

Figure 1 is a vertical sectional elevation taken transversely through the temporary binder on the line l 1 or' Fig. 2 and illustrating my improvements. Fig. 2 is a horizontal sectional plan view in the plane of the dotted line 2 2 of Fig. l. Fig. 3 is a vertical transverse sectional elevation, the plane of the section being indicated by the dotted line 3 3 of Fig. l, looking in the direction of the arrow; and Fig. 4 is a detail perspective view of one section of the extensible post.

member thereto, although the post member may be attached in a permanent manner to the cover A by any other suitable means. Y

This member B of the post is hollow or provided with a longitudinal passage U, and the upper end ot said member is provided with a dovetailed tenen c, said tenon being' arranged centrally with respect to the post member and providing shoulders on opposite sides oi said post member.

Each post may consist of two or more members, such as O D E. The members O and D of the post are complements one oi the other, each ot' said members having a dovetailed recess d at one end and the dovetailed tenon c at theother end. The parts may be assembled for the tenen of one member to enter the recess of the other member, so as to secure the desired interlocking of the members one to the other endwise in series, thereby preventing separation ol the several members in an endwise direction. the post is provided at its lower end with a dovetailed groove d, which may have interlocking engagement Awith the dovetailed tenon on either of the other members B, C, and D of the post, accord ing to the number of leaves which are to be contained in the binder. It is evident that if a small number of leaves are to be used the post members O D may be omitted and the member E may be intel-locked directly with the memberfB; but as the number ol leaves increase the members O and D are added successively to the member B and to one another, in which case the member E is coupled to the members O or D, as the case may be.

The members C, D, and E are hollow or The upper member E of provided with longitudinal passages similar to the passage and these passages of the several members are adapted to receive the internal locking-pins F Gr. as shown by Fig. 1. The locking-pin F is adapted to be slipped into the members B and C of the post in a way to prevent lateral separation of the tenons from the grooved ends of said members; but the locking-pin G is adapted to enter the members D E of the post and to have locking engagement with the member E and with the upper cover A. This locking-pin Gr is provided with an enlarged and male-threaded portion g and with a head g'. The upper member E is provided with a reduced upper extremity e, forming an annular shoulder e, said reduced end being thrust through an opening c', which is provided in the metallic plate of the cover A. The post member E is provided in its reduced end portion e with a female thread, and when the pin G is thrust into the members E D said pin may have its threaded portion g screwed into the femalethreaded portion e of the post member E, whereby the head 'g' of said pin is adapted to bear on the outside upper cover A in a way to bind the cover lirmly to the upper ends of the posts.

It will be seen that the locking-pins F G pass through the several .members of the post in a way to prevent them from moving laterally one upon the other, and thereby coniine the post members in their alined relation. If it is desired to shorten the post, the pin G is removed by unscrewing it from the member E, after which the cover A"may be disconnected and one or more of the members C D E may be removed. If a short post is desired, the pin F is removed and the member E is coupled directly to the member B, after which the pin G is inserted in order to attach the cover A to the short post and to retain the members B and E in operative relation. If the size of the book increases, the member C may be coupled to the members B and E, and the pin G is used to hold the members in position and to attach the cover A to the post.

I prefer to employ two posts constructed as just described in the binder, and these sectional posts are provided on their opposing faces with the series of ratchet-teeth indicated at 7L, each member of the post having a number of said ratchet-teeth. The tenons and grooves are provided in the members ofthe post, so that the ratchet-teeth will take the proper positions when the post members are coupled together by fitting the tenon of one post member in the groove of the other post member, thus insuring precision and certainty in the assemblage of the parts comprising the posts.

As is usual in some classes of binders, the posts support a locking-Slat I, which is tted slidably over the posts and is adapted to rest upon the group of leaves .contained in the binder. This locking-Slat is provided with suitable devices adapted to have engagement with the ratchet-teeth 7L of the posts in a way to prevent the slat from lifting under the resistance of the leaves. In Fig. 2 I have shown a suitable form of locking mechanism adapted to be carried by the slat I, and in this ligure the slat is shown as being of hollowed or chambered construction for the accommodation of bolts J. The bolts are confined for slidable movement within the chambered slat by suitable devices, and they are normallyimpelled in opposite directions by springs y'. The free ends of the bolts are presented for engagement with the teetlrof the ratchets L on the two posts, and the inner ends of said bolts have overlapping relation yto allow a key to have engagement therewith for the purpose of retracting the bolt simultaneously from engagement with said ratchets of the posts.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a temporary binder, an eXtensible post consisting of sections provided with tenoned and grooved ends adapted for interlocking engagement, and means for holding the members against lateral separation.

2. In a temporary binder, a sectional post consisting of hollow members, one member being provided with a dovetailed tenon and the other member havinga dovetailed groove adapted to receive said tenon and to have interlocking engagement therewith to hold said members against endwise separation, and means within the hollow members for confining the members against lateral separation.

3. In a temporary binder, a sectional post having hollow members each provided with a series of ratchet-teeth, one of said members being provided with a dovetailed tenon and the other with a dovetailed groove, and a pin insertible in said hollow members for holding them against lateral separation.

4. In a temporary binder, a sectional post ,having its members provided with ratchetteeth, two or more of said members having dovetailed tenons and dovetailed grooves, and a locking-pin insertible in the members of the post and adapted to have interlocking engagement with one of said members.

5. In a temporary binder, the combination with leaves, of post members attached to one of the covers and provided with dovetailed tenons, other post members having ratchetteeth along one side and grooved and tenoned ends interlocked with the first-named post members, and threaded pins screwed into upper post members and conlining an upper cover thereon.

6. In a' temporary binder, a separable post IOO IIO

ends by interlocking tongue-and-groove joints and held thereby against separation endwise, and means extending across the joints between the members for coniining them against lat eral separation.

7. In a temporary binder, a separable post havinga plurality of hollow members coupled endwise by interlocking tongue-and-groove joints, and pins insertible in said members and extending' across the joints between them for holding the members against lateral separation.

8. In a temporary binder, aseparable post havingaplurality of hollow members coupled endwise by interlocking joints, suitable covers to which the end members are fitted, and a headed screw having threaded engagement with one member of the post and clamping the cover firmly to said post, said screw eX- tending into the separable post and across the joint between the members of said post.

9. In a temporary binder, suitable covers, a separable ratchet-post having hollow mem bers coupled endwise by interlocking joints, one member or' the post being fixed to one cover and another post member iitted to the other cover, and a screw threaded into a post member and clamping the cover thereto, said screw extendingl into the hollow post and across the joint between the members thereof. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
