Each section is provided at the front and rear margins of the outer faces of its end portions 9 with vertical strips 27, which abut against the corresponding strips of the laterally-adjacent sections when assembled in horizontal tiers, as clearly indicated in Fig.

section by screws 32 or in any other suitable manner. The plate 30 is provided with acentral aperture 33, and the plate 31 is provided with a corresponding central aperture 34. On the inner face of the plate 31 is provided a bridge-piece 35, located within the aperture or recess 29 and havinga central aperture 36 in line with the aperture 34. A clamping-lever 37 is pivoted to one arm of Athe bridgepiece 35, as indicated at 3S, and is provided with an aperture 39 slightly larger than the Said clamping-lever is provided with an operating stem or handle 40, which extends through a slot 4l in the bridgepiece 35, and a spring 42, secured to the bridge-piece, bears with its free end against the free end of the clamping-lever 37, said spring being provided with a large aperture 43 for the unobstructed passage of the connecting pin orbolt,hereinafterdescribed. All

'these parts lie entirely within the thickness of the end piece 9, so that they do not project into the interior of the section. The connecting pin or bolt is indicated at .44 and is provided with a head 45, by means of which it may be grasped. Said pin or bolt passes somewhat loosely through the apererture 33 in the plate 30 and more snugly through the apertures 34 in the 4plate 31,-and 36 in the bridge-piece 35. The aperture 39 in the clamping-lever 37 is of such dimensions that when said lever is at or near a position at right angles to the pin or bolt 44 said pin or bolt is clear from contact with its walls; but when said clamping-lever is inclined to a sufficient extent-as, for instance,

as indicated in Fig. 7 of the ydrawingsthe margins of the aperture 39 will bear upon the pin or bolt in such a manner that, while it permits said pin or bolt to be moved in the direction indicated by the arrow in said iignre, it will prevent itsv movement in the opposite direction. This is due to the fact that movement in the direction of the arrow tends to move the clamping-lever in such a way as to free the pin or bolt from the binding action of the walls of the aperture therein, while movement in the opposite direct-ion tends to cause the margins ot' said aperture to bite said pin or bolt, and thereby prevents its withdrawal. The spring 42 serves to always hold said clamping-lever in operative position to prevent withdrawal of the pin or bolt except when said clamping lever is moved against the action of said spring by pressure of the finger upon the stem or handle 40.

It will be understood that in assembling the'sections or units together horizontally they are brought into position sothat their end strips 27 abut against each other, and the aperture 33 of the plate 30 of onesection is oppositethe aperture 34 of the plate 3l of the adjacent section. All that is necessary to firmly unite the sections is to insert the Vpin or bolt 44 through the apertures 33 and 34 in the plates and through the apertures 39 in the clamping-lever 37, which will freely permit the passage of said bolt in the manner just described. When the head 45 of the pin or bolt bears against the inner side of the plate 30, the two sections are iirmly vlocked togetheigsince any attempt to separate them will cause the clamping-lever 37 to bite upon the pin or bolt 44 and prevent such separation'. The sections may, however, be readilyseparated by inserting the inger into the-recess 29 and pressing upon Ythe stem or handle 40, whereupon the pin or bolt is released and may be withdrawn by means of its head 45. lt will be observed that the pin or bolt is of such length that when inserted in position to unite the parts neither it nor any of its associated mechanism projects beyond the inner faces of the end pieces, so that the interior of the sections is entirely unobstructed. At the same time all external projections on the ends of the cases are done away with, and all danger of injury to garments `of the vperson by becoming entangled with or striking against said projecltions is done away with.

rPhe units constructed in `the manner described may be assembled together either in vertical or horizontal rows, or in both, so as toconstitute a book or other case of any desired capacity, which may be increased or diminished at will by the removal ,or addition vof other sections or units.

VithA regard to theisectionsin thesame horizontal row they may 4be united by simply bringing their ends together until the Ystrips 27 abut, .whereupon the locking pinor bolt 44 may be inserted in the mannerhereinbefore describedand will lock the sections together so that they will be held irmly in place. The sections may be separated horizontally by inserting the hands within the adjacent sections, releasing IIO the clam ping-lever 37 with one hand and withdrawing the locking pin or bolt 44 with the other. It will be observed that the devices for connecting the sections at their ends do not project into the interior of the sections when in position, and when the sections are separated they do not project externally in such a manner as to cause damage.

It will be understood, of course, that in order to complete the case a top 46 is employed, grooved and recessed on its under side to t the upper portion of the section below it and finished above in any suitable manner, as indicated in Figs. l, 2, and 3.

We do not wish to be understood as limiting our invention in its application to bookcases only, as it is obvious that a similar construction may be applied to cases and cabinets of variouskinds-as, for instance, either cabinet-s or individual units, such as commercial iiling cabinets or units,consisting of letter, catalogue, card-index, or check files, pigeonhole cases, document-tiles, and various other devices of office equipment. Furthermore, we do not wish to be understood as limiting ourselves to the precise details of construction hereinbefore set forth, as said details may be varied without departing from the principle of our invention. For instance, the particular form of connecting device between the ends of the sections may be varied, and in Fig. 8 of the drawings we have shown a modification, in which plates 47 and 48 are employed, corresponding to the plates 30 and 3l, the plate 48 being, however, centrally enlarged and threaded, as shown at 49, while a bolt or pin 50, corresponding with the bolt or pin 44 and having a head 5l, .corresponding to the head 45, is employed, said bolt or pin being threaded to screw into the threaded aperture of the plate 4S. It will be observed, however, that in this case, as in the case of the constructionl shown in Figs. 5, 6, and 7, the fastening devices are entirely protected and concealed within recesses in the ends of the sections, so as to not project into the interior oit' the saine and so that when the sections are separated there are no external projections.

We claim- 1. In a sectional book or other case,the combination, with the meeting ends of two sections or units, having apertures extending from the interior to the exterior and plates for closing the outer ends of said apertures to form recesses opening into the interior of the sections, said plates being provided with apertures smaller than those which form the' recesses, of a connecting bolt or pin adapted to fit and engage said apertured plates and havingits ends located and terminating within the recesses inward of the inner faces of the end walls of the sections, substantially as described.

2. In a sectional book or other case,the combination, with the meeting ends of two sections or units having opposite apertures extending from the interior to the exterior, and apertured plates closing the exterior of said apertures to form internal recesses,one of said plates being provided with a bridge piece and with a clamping-lever pivotally connected therewith, of a locking pin or bolt adapted to extend through said apertures and be engaged by said clamping-lever, substantially as described.

3. In a sectional book or other case,the combination, with the meeting ends of two sections or units, apertured as described and provided with apertured closing-plates, of a bridge-piece mounted on one of said plates within the aperture, an apertured clampinglever pivotally connected to said bridgepiece, and provided with an operating stem or handle, and a spring for holding said ciamping-lever in an oblique position, and a connecting bolt or pin having a body adapted to extend through said apertures and engage the clamping-lever, and a head to bear against the inner face of the other plate, substantially as described.

4. In asectional book or other case,the combination, with the meeting ends of two sections or units having apertures closed by apertured plates, to form inwardly-opening recesses; of a removable connecting bolt or pin provided with a head to engage theinner face of one of saidplates, the other of said plates being provided with means for engaging the body of said bolt or pin, when inserted, and said bolt or pin terminating in said recessesinward of the inner faces of the inner end walls of the sections, substantially as described.
