Speoication of Letters Patent.

Patented Aug. 19,1913.

Application filed Hatch 14, 1812. Serial No. 683,309.

To all whom it ma concern le it known t iat l, FRANK H. CRUMP,

citizen of the United States, residing at Los y the necessity of removingthe covers of thel binder.

The invention contemplates-the provisiom.

a binderofv this classz'oclamping mem'- bers which are connectedby means of posts comprising telescopic sections, one clamping members carryin ymeans for ad justably clamping `one of 1e said post sections andhaving secured thereto one .end of the other sections of each post.

held at relative adjustment within certain limits so as to permit of the insertion offa number ot extra. building up the posts by the use of addi-l tional sections.

Jinother aim of the invention is to provide means so arranged upon the leaf-supporting to prevent the leaves or retaining posts as held by the binder becoming relatively dis-l placed when the clamping members o the binder are separated, for the insertion or removal o leaves.

A. further object of the invention is to provide within the posts, means for automatically extending the sections thereof when the binder is unlocked.

For a full understanding of the invention reference is to be had to the following description and accompanying drawing, in which Figure 1 is a view partly. in elevation and 4partly in longitudinal sectionbf the .binder embodying the present invention, Fig. 2 is a detail verticalv transverse sectional view through ajportionthereoj Fig.,` 3 is a def tail view partly in elevation andA partly in ot leavesv Bysuch a construction, the clamping members, may be leaves if desired without' section illustrating an element employed in buildingl up the posts of the binder.

Corresponding and like parts are referred to in the following description and indicatedin all the views of the accompanying drawing by the same reference characters.

In the drawing, the lower clamping member of the binder is indicated in general by the numeral 1 and the upperclamping member is indicated by the numeral 2. The lower clamping member includes a flat tubular body member 3 against the under side of which there is disposed a filler 4 which may be secured directly to the body-member 3 or may be held thereto by the usual binding (not shown) which covers the back-boards of the binder.

, The upper clamping member of the binder consists of a' iiat tubular body 5 which corresponds to the member 3, and a filler 6 corresponding to the filler 4. The back-boards of thebinder, are secured to the clamping membersl 1 and 2 by meansof hinges, each consisting o fa air of attaching plates 7 secured between t each clamping member and supporting a hinge-rod 8 upon which are carried a number of leaves 9 secured in any suitable manner to the'respectivebaclrboard For apur- Yose to be presently explained, the upper and lower walls of the hollow body 3 o the clam in member l are formed with vertical y a ined openings 10 and 11 and the filler 4 of this clamping member is vformed with an opening 12 which registers with the opening 11.

A strip 13 is secured in a recess formed in the under side of the filler 4 and closes the lower end of the opening 12 as shown in Figs. 1 and 2 of the drawing. Also, :for a purpose to be presently explained, the walls of the bod 5 of the clamping member 2 are formed with vertically alined openings lll and the filler 6 is formed with an opening l5 and a countersink 16.

Each of the leaf-holding posts of the binder includes a section 17 which has its i lower end threaded into an opening in the strip 4 as at 18 and indented as at 19 so as to prevent its removal or accidental disengagement, and this section of the post is ormed or provided at its up er end with a head 20. lach post also incibdes a section i 21 which is interiorly reduced in diameter e tubular body and filler of I at its lowerend asat 22 and the lsections17. and 21 'are` assembled-with the. latter slidably receiving the former., Byiproviding the section 17 with'the head :20 andini-` teriorly reducing the section 21 complete separation of the sections isprevented. As'

creased in diameter as at 23 and interiorlyv decreased in diameter as at 24, it being interiorly threaded to receive' a plug 25 which is irovided with a milled head 26, the perip iery of which projects beyond the exterior surface .of the section at its said end. The said up er end of the section fits slidably throup when the c ampinff members of the binder are fully separated the head of the plug 25 as illustrated in Fig. 1. By interiorlyv reducing the section 21 at its u er end a shoulder is formed against whidli bears the upper end of a spring 27 housed Withinthe said section. The lower end of this spring bears against the head 20 at the upper end of the section 17 and the spring being'under compression it at all times tends to relatively separate or extend the sections1 17 and 21,3su'ch extension bein ,'hoyvever, nori. mallyprevented throught e mediumof a locking device' housed Within th'e'ibody 3 of the clamp` g member 1 andl coperating with the section 21 ofthe post. Theloekingdevice mentioned above consists of a, channelbar 28 which is slidably arrangedwithinl the bodyy 3 and yhas the lowery edges of its anges resting 'upon the bottomwall of the said body member 3 and its connecting portion 1 ing immediately beneatli the upper wall o the said body.r The said connecting portion of the channel bar is formed with openinvs 29 which register with the openings 10 when the bar is in one position, but are arranged to be brought out of registration when the bar is a justed longitudinally Within the said body. In one end of the bar 3 there is lixed'a plug 30 into which is adjustably threaded a stem 31 carrying a collar 32 which is rotatably conlined within the body 3 but held against displacement longitudinally thereof. Beyond the collar 33 the stem 31 is s uared as at 33 for the engagement-therewit of a suitable key (not shown) by means of'v which the stem may be rotatedy so as to adjust the channel bar within lthe body. At this point it will be readilyund'erstood that whenthe openings 29 are in registration with" the openings 10 .the lower endportion of the section' 21 of'eacli of thel leaf-holding posts vmay begslidabl i adjust adjusted through the said openings and t rough the openings 11 and 12.' However, when the clamping members 1 and 2 are in closed relation, and the stem 31 has -been adjusted so as to longitudinally the channel bar 28 within the body 3 and bring the openings 29 out of registration'with the openings 10, the walls of said o enings 29 will bind the sections 21 against t ie walls of the openinos 10 and the sections of the posts will be held against relative separation or extension, thereby holding the clamping members against separation.

From the foregoing it will be readily understood that the leaves of the binder are to be fitted to the posts in the usual manner, and that they are to be clamped between the members 1 and 2. It will also be understood that when it is desired to insert new l leaves or to remove certain leaves, the stem the openinvs 14 and 15 and 31 may be rotated so as to cause the o cnings 29 in the channel bar 28 to register with the openings 10, thereby releasing tlie will be' received Within thev countersink 16,

sections 21. The s rings 27 will then iin- ,mediately act to lift the clamping member 2 and permit of the insertion or removal of the leaves. it will furthermore be noted that the walls of the openings 29 engage with the sections 21 `of the posts a considerable distance above the lower ends of these sections so that anumber of additional leaves may be inserted Without the necessity of increasing the length of each post.

As a means for preventing relative displacement of the leaves when the clampingr members 1 and 2 are separated, a sleeve 3e is loosely ftted'u on each post section 21 and these sleeves, eing of a diameter substantially equal to the exterior diameter of said sections 21, and of considerably greater diameter than the sections 17 hold the leaves against engagement with the said sections 17.

In Fig. 3 of the'drawing there is shown i oneof anumber of sections which may be employed in building u the posts so as to increase their length an this section is indicated by the numeral 5 and is of substantially the same diameter exteriorly as the enlarged upper end 23 of the section 21. The section 35 is formedy at one end with a threaded stud 36 of a size to tit within the threaded upper end of the section 21 after the plug 25 has been unscrewed therefrom and is formed in its op osite end with a threaded socket 37 whic may receive the stud 36 of the companion section 35, 0r may receive the headed stud 25.
