To all 1071 0122, itmay concern:

Be it known that I, HENRY-O. MILLER, of

.Milwaukee, in the county of Milwaukee and State ofW'isconsin, have invented a new and useful Improvement in Temporary Binders,

of which the following is adescription, refer ence being had to the accompanying drawings, which are a part of this specification.

My invention has relation to improvements in temporary binders.

, The invention relates more particularly to that class of binders in which leaves are placed and secured between the side pieces accommodate the increased number of leaves.

- The invention also contemplates as an object an improved form of locking mechanism.

With the above and other incidental objects in view the invention consists of the devices and parts or their equivalents, as hereinafter more fully pointed out.

In the accompanying drawings, Figure 1 is a perspective view of a temporary binder involving my invention. Fig. 2 is a plan view of the upper plate, the leather or other covering being removed, and also showing a fragment of the lower cover-section of the book. Fig. 3 is a front view of the plates constituting the frame, portions being broken away, the figure being a view at right angles to Fig. 2. Fig. 4: is a view of two of the removable posts Fig. 5 is a view showing a form of removable post which is adapted to be. turned freely in either direction toa limited extent, the view being a horizontal section through the post and looking down upon one of the leaves of the book and upon the upper side of the lower cover-section. Fig. 6 is an elevation of the form of construction shown in Fig. 5. Fig. 7 is a sectional View through the metallic plates, showing the removable post as consisting of telescoping secbinding-strip 10.

tions; and Fig. 8 is a View through the upper telescoping section of the form of post shown in Fig. 7, looking down upon the lower cover- 5 5 The numeral 11 indicates the other cover section, provided at its rear with a similar ploy posts 14, which have their lowerends threaded. These threaded lower ends are adapted to engage threaded openings in one of the binding-strips of a cover-section. As is well understood in this class of inventions, the rear binding-strips are usually composed of metallic plates which are covered by leather or other suitable covering' In the illustration of my invention I prefer to show such plates, although I wish it distinctly um derstood that I do not limit myself to the use thereof, as the omission of such plates is within the spirit and scope of my invention, and the binding- strips 10 and 12 may be formed of any suitable material. The lower metallic strip is indicated throughout different views of the drawings by the numeral 15, and the upper metallic strip by the numeral 16. The lower threaded ends of the posts 14 in the form of construction shown in Figs. 1 te l are shown as engaging threaded openings 17 in the metallic strip 15, while the upper striplfi is provided with plain or unthreaded openings 18, through which the posts are adapted to pass. The upper ends of the posts iare'advisably formed with nicks for the engagement therewith of a screw-driver, so that. after such a quantity of leaves has been adjustedbetween the cover-sections the lengths of the posts will not permit the insertion of additional leaves. These short posts may be turned until their threaded ends are disengaged fromthe threaded openings 17, thereby permitting these posts to be removed and longer po t Fig. iof the drawings openings 19 in the leaves 13, and I prefer that the leaves'be formed with slots 20, extending fromthese openings to the rear edge of said leaves, so as to provide for the leaves being readily removed when desired. If re ferred, however, merely round openings in theleaves may be provided.

In Figs. 5 and 6 of the drawings I show a form in which the post indicated by the numeral I I is not only removable,'but also revoluble in either direction. To accomplish this function, I provide the lower metallic strip with unthreaded openings 21, in each of which is fitted a sleeve 22, said sleeve formed with top and bottom flanges 2328', which embrace the metallic strip. The sleeve is interiorly threaded, and the lo'we'r'threaded end of the post is adapted to be turned therein. If desired, the extent of the-turning of the sleeve 22 may belimited by means of a pin 24, extending downwardly from the under side of the metallic strip15, said pin being adjacent to a cut-out portion 25 in the periphery of the bottom flange 2 3. It will be evident that the shoulders formedat opposite ends of the cut-out portion will contact with the pin 24, and thereby limit the extent to which the sleeve can be turned in either dimotion. This construction of flanged sleeve is the same as that covered in the United States Letters Patent issued to myself and Julius Bauer on August 10, 1897, No. 587,986,

.for improvements in temporary binders, it

being'illu'strated on the drawings of the present invention in order to show that a removable post can be applied thereto so as to make the post both removable and revolupost.

ble. The sleeve covered in the Letters Patent aforesaid, however, was made a part of a section of a telescoping post and did not have a threaded connection with the section of post, as in the present invention.

The form of post preferably used in the arrangement shown in Figs. 5 and 6 is a post oblong in cross-section, so that when the post is turned so as to present its greatest width across the opening 19 of the leaf, which greatest width is greater than the width of the slot 20, the leaf is locked in place, whereas if the post is turned so as to present its greatest width in line with the slot 20 the leaf can be readilywithdrawn from engagement with the It will be obvious, however, that in this form of construction a post round'in crosssection may be employed either in connection with a leaf having merely a round opbningor a round opening having a straight slot extending therefrom and satisfactory results se cured. The construction shown, however, is preferable. fact that in the construction shown in Figs.

1 to 3'an oblong or similar form of post could alsobe employed instead of the round form shown, especially when leaves are used having openings therein for the reception of the Attention is also calledto thethread so as to bring, its greatest width in line-with the ,slot 20. H

In Figs. 7 and 8 I show the application of my invention to a telescoping post, whereby a lengthening to a certain extent is effected by the raising of one post within the other. I show a tubular section 26, having a lower threaded end engaging the threaded opening 17 of the lower metallic strip 15 and an up the'lower section therewith, so that both sections together will be disengaged from their respective threaded openings. When the upper cover-section has been raised to such an extent that the lowerend of the upper-postsection 27 is almost out of the bore of the lower tubular section, it then becomes necessary to remove the two sections and substi- The upper extremity of section.

tute others of greater length, which of course is accomplished in the manner just pointed out. \Vhile it is preferred in this form of construction where telescoping post-seetionsare employed that bothsections be removed, yet it is obvious that successfulresults might be obtained by merely making one section removable. Again, while in the description of this form of device I have described the two sections of the post as of oblong shape" in cross-section, yet, if preferred, they need not necessarily be of this particular form, but may be square or rectangular. In fact, round sections may be employed, if desired. In the latter instance, however, some suitable means should be provided for causing the lower tubular section to turn with the upper section whena screw-driver or other turning tool is applied to said upper section. I would also call attention to the fact that, ifdesired, in the form shown in Figs. 7 and 8 the lower tubu-' lar post-section may-have a threaded connection with'aprevoluble sleeve, such as that shown in Figs.. 5 and 6. In such case, therefore, I would thereby provide removable telescoping and revoluble posts.

. While any suitable locking mechanism may .be employed for holding one of the cover-seccess 30. In this recess is slidingly mounted the ward of akey inserted through the keya bolt 31, one end of said bolt being pivotally y the strips'29 is thereby relieved, so that the form. The belt is also formed on .one edge connected to the inner ends of two arms 32 32, the three parts forming a toggle-joint. The outer ends of these arms are fitted in recesses 33 33in the metallic strips 29, the ends. of the arms being preferably rounded and the recesses being of a corresponding with oppositely inclined or beveled surfaces 34 34, which are adapted to be engaged byopening 35. When the key is passed through said opening and turned in one direction, it will act on the inclined surface 34 and shoot the bolt in one directiomso as to thrust the pivoted ends of the arms 32 toward theedge of the strip 16. This will forcethe ends of rection to force the-strips 29 outwardly and cause the edges of the openings 36 36. of said strips to bear firmly against the posts 14, said posts passing through the openings referred to. By this movement it is obvious that the upper cover-section is maintained at adjusted position. When the key is turned in an opposite direction, so as to act against the beveled surface 34, the bolt 31 is drawn inwardly, and pressure of the arms 32 against cover-section may. be readily adjusted to another position. It will be noticed that the openings 36 are of such greater diameter than the posts 14 as to permit slight play of the plates 29, and thereby make it possible forsaid plates to be moved to locking position, as just described. The strips 29 are held to the strips 16 by means of screws 37. These screws pass through plain openings 33in the strips 29, which openings are also of such greater diameter than the screws as to permit of a slight play of the strips 29. also be noticed that the bolt 31 is provided 1 It will on one edge with a recess 39, into which recess a pin 40 extends. When the bolt is moved, this pin contacts with the shoulders formed at the ends or the recess 39, and thereby limits the extent of the movement of the bolt in What I claim as my invention is.--

.either direction. The toggle-joint-locking mechanism is advisably covered by a plate 41.

F1. The combination, of longitudinal strips,

-a threaded end fitting the internal threads of the sleeve, and said post or posts entering I the opening or openings of the other longitudinal strip.

2. In a temporary hinder, the combination,

of parallel longitudinal strips, posts extending from one of said strips and through openings in the other strip, short strips superimposed upon the last-mentioned strip, said short strips having their, inner ends a distance from each other so as to leave a space therebetween, and. said stripsprovided with openings through which the posts pass, the openings being of such greater diameter than the posts as to permit of a slight movement of the strips, a bolt seated on the longitudinal stripin the space between the inner ends of the short strips, arms pivotally connected to the bolt and having their outer ends engaging the ends of the short strips, and means for actuating the bolt.

In testimony whereof I afiix my signature in presence of two witnesses.
