To all whom, t may concern/.j

Be it known that l, WILLIAM R. WOLF, a citizen of the United States, residing at Burlington, in the county of Des Moines and State of Iowa, have invented certain vnew and useful Improvements in Sectional Bookcases; and I do hereby declare the following to be a full, clear, and exact description'ofthe invention, such as willenable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in bookcases, and more particularly to the sectional type; and the objectin view is the production of a section or separate individual cell capable of conjoint use with a plurality of similar sections or cells, whereby a bookcase or cabinet is produced.

With this and other objects in view thein- Vention consists in certain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure l represents a perspective view of a plurality ofsections embodying the featuresl of myinvention secured together for forming abookcase or cabinet, one of the sections being removed to show the connecting structure. Fig. 2 represents a vertical central section through one of the cells orsections, this particular section being provided .with a base and top closure. Fig. 3 represents an enlarged detail perspective viewvof` one of the one of the connecting members or screws, the

surrounding parts being shown in section. Fig. 8 represents a detail section of one of the rear corners of a cell or section, illustrating the retaining means for the back of the section. Fig. 9 represents a view similar to Fig. 4, showing a plurality of sections in lateral relations. Fig. 10 represents a fragmentary vertical section through a plurality of cells or sections.

Referring to thevdrawiugs by numerals, 1 indicates an intermediate section, 2 a top section, and 3 a bottom section. ,A Each of the sections is alike, except that, as sc eninFig, 2, which l.represents a compoundingof the top and bottom vvsections,th`e `top section has a suitable top closure, as 4,'and thebottom section a'4base,'as 5.... The base is-provided with a bottom',1as 6, preferablyheld ,in position by tongue-and-groove",connection with the walls of the base. The` intermediate sections are formed by the omission of the top 4 and the base.l 5, and each of said intermediate sections comprise two side walls, as 7 7, each wall having its rear end rabbeted forreceiving the edges of a suit-able back, as 8, each of the edges being formed with a plurality of apertures, as.V 9, for receiving securing means, as will be Vhereinafter mentioned. Each of the intermediate sections l is provided with a suitable bottom, as l0, formed with a transverse concaved groove, as 11,-near its front end Iand in its under face, as will be hereinafter specified. Each of the sides 7 has its upper and lower edges providedwith comparatively deep grooves extending the full length thereof, andthe upper groove is designed to receive and retain a locking or fastener` bar, as l2. Each bar l2 is formed of a suitable piece of material, preferably flat metal, and formed inv its upper and lower edges with a plurality of rearwardly-directed angular notches, as 13-13. The rear end of bar l2 is bent at right angles to the main body portion thereof and provided with a plurality of lugs 14 14, projecting forwardly and designed in operation lto engage apertures 9 for retaining the back 8 in position. The forward end of the bar l2 is preferably tapered and threaded, as at l5, for receiving a suitable nut 16 or 16', the former being a wing-nut and the latter a sleeve-nut. Extending transversely of each of the upper edge grooves are applurality of bolts or engaging bars, as 17 17,*designed to be engaged by the lower notches 13 of bar l2 for permanently but slidably retaining the said bar within the upper edge groove. The lower edge groove of each side wall 7 of each intermediate section is designed to inclose the upper edge of its corresponding lloo bar 12, and the bottom 10 of this superimposed section is provided with a plurality of engaging members, as 18, each preferably a screw the head of which is passed through an aperture, as 19, in its corresponding wall 7 and through notch 13 of the upper edge of bar 12, whereby when the said bar is drawn forward, so that the angular portion of the notch 13 engages the member 1S, the head thereof will be held against removal and the side wall, bottom, and two sections will thereby be securely held together. It will be noted that bar 12 is free to slide longitudinally for a short distance, whereby it may be caused to engage or be disengaged from the members 1S, and the same forward movement which causes the engagement with the said members will also cause the lugs 14 to engage apertures 9, and thereby securely retain the back 8 in position. The front end of each bar 12 is provided with a binding-block, as 20, the upper end of which engages the upper section and the lower end engaging the lower section, whereby tightening of the nut 16 or 16', as the case may be, will cause the upper and lower sections to be brought into exact alinement by the contact of said block.

One of the sides 7 of each section is provided with a laterally-opening aperture registering with one of the notches 13, preferably one ot' the upper ones, not engaged by members 18and in the opposite wall 7 and exactly in the same relative position is a suitable laterally-projecting engaging screw or bolt, as 18', whereby each section may have its laterally-projecting screw passed through the aperture in the side wall of the next contiguous section and engage the bar 12 thereof for securing the two sections together. It will thus be seen that when the parts are assembled to form a complete section and a plurality of sections are assembled to form a cabinet all that is necessary to dismantle the entire structure is to loosen the nuts 16 and move the bars 12 rearwardly, whereby the notches 13 will no longer engage members 18 and 18' and lugs 14 will be free from engagement with apertures 9, thereby leaving the sections to be separated and the sides, back, and bottom of each of the sections free to be separated. A reverse movement of bars 12 will again firmly lock all parts of each of the sections together and also secure together all of the laterally-arranged sections.

In practice I find it desirable to provide a suitable door to each section, and any suitable door proper, as 21, may be employed provided with an operating-handle, as22, designed to be grasped for swinging the door outwardly upon its laterally-extending pivotal supports, as 23 23, each of which engages a horizontal groove, as 24, in its respective wall '7, whereby after the door 21 has been swung to a horizontal plane it may be passed rearwardly, guided by supports 23, engaging grooves 24, and retained in the upper portion of the section. A roller, as 25, is supported in contact with door 21 on each of walls 7, whereby the said` door will have its frontend supported when in a horizontal position, its pivotal supports being at the rear of slots 24 and supporting the rear end of the door, and also whereby the said door when in a vertical position will be prevented from falling inwardly. The upper end, as 26, of door21 is curved, and of course that portion above the pivotal supports will move in the arc of a circle on a comparatively small radius, and in the intermediate sections the concaved portion 11 in the bottom of the next upper section affords sufficient room for this swinging of the upper end of door 21. At the same time it will be understood that when the door is in a vertical position the curved upper edge thereof will lie close to or in contact with the front portion of concave 1l, whereby the door will be prevented from falling outwardly.

Although I have specifically set forth one particular embodiment of my invention, yet I do not wish to be understood as limiting myself to the precise structure described, but shall feel at liberty to deviate therefrom to a degree within the spirit and scope of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
