tul Improvements in Knockdown Sectional Furniture, of which the following is n specificetion.

One of the objects of this invention is to provide means for connecting together the parts of an article of furniture or of a. furniture section so that said parts may be con veniently separated in order that the article or section may be shipped or stored in compact form, and so that said parts may be readily assembled to form the complete article or section.

Another object ol' my invention is to provide means for uniting the sections of a sec tionel bookcase or other article of furniture. A further object is to provide improved means for interlocking adjacent stocks or tiers of sections.

A further object is to provide improved means for causing the door of a bookcase section to move in and out without twisting or binding.

A further object is to-provide improved means for rcmovnblv supporting the door in the section.

The invention also relates to the other improvements in knockdown scctional turniture hereinafter set forth.

In the accompanyingdrawings, Figure l is a perspective view of a knockdown sci-.- tional bookcase consisting of a. base, a. book section and s top, and mnbodying the fen- Fig. .2 is :i perspective view showing the under side oi the top section. Fig. 3 is a pcrspcctivc view of the book section. hose section. Fig. 5 is :l frag-mental vertical sectional view taken through the top section and the book section next below it. Fig. 5 is a cross section of he bottom oi" the bookscction. Fig. 7 is a l'rngmcntal vcrticnl section through one cud and the bottznn of :r book section; Fig. 3 is it section on line 8 8 of Fig. 7. Fig. i) is :1 perspective view of a. port-ion cf the moons or uniting two vcrticcliy alincd sections. Fig. 10 is a vertical sectional view through the door. if" ii is a fragmentnl perspective view of he door and its supporting means. tig. 12 is a.

Fig. 4 is a similar view of the spective view showing the construction of each end well of the book section. Fig. i3 is at sectional viewillustrating the means for interlocking adjacent stacks. Fig. 14 is n perspective view of one of the interlocking members.

In the embodiment selected i'or illustrattion, each book sectlon' 1 consists oi two ends 2, a. bottom 3 ands back i. The joint between the ends and the bottom, in this instance, consists of the connection shown in Fig. 7. he lower edge of each end well 2 is robbeted at 5, a. groove 6 being formed in one wall of the rabbet and e dowmvzn'dly extending rib 7 being provided at the inner face of the end. in. each end of the bottom is formed a groove 8 to receive the rib 7, a rib 9 on said bottom entering the groove 6. The bottom is rebbeted at 10 to provide between it and the end 2 a groove 11 for e purpose to appear hereinafter. The rib 9 is not semicylindricnl in form, the lower side of said ribbeing curved on the :LPC of a circle of larger diameter then that upon which the upper side is formed, thus giving said riirthc shape indicated in Fig. 7. The groove 6 conforms in shape to the rib 9. The end and the bottom are connected by placing the end 2 upon the bottom 3 with said end leaning inward, inserting the rib $7) in the groove 8, end tilting the end 2 into an upright position, the rib 9 entering the groove 6 as the end reaches a. vertical position. When the ports are thus intcrz-mgnged, tilting of the end 2 outward post a vertical phnio is prevented. The ends 2 are properly positioned upon the bottom 3 by means of e rn'ojecting portion 12 upon each end 2, :tdaptcd to lie within a notch 13 formed in each end of the bottom (Fig. 8). The upper ends of the end wzdls 2 are tied together by a rod 1,4- hoving down-turned. ends adopt ed to lie in openings 16 formed in said ends The back 4 is mounted in vertical grooves 17 (Fig. 12) formed in the inner feces of the ends 2, in n groove 18 (Fig. 6) in the upper side of the bottom 3, end in n groove 19 in. the bottom of the top section 20 end the lower side of och bottom 3. The winners tion between two vertically?"ned book so tions comprises, in this inst formed upon the upper en wall 2 and adapted to enter the roove i In the ends of the top section 20 ere formed g sins/2e grooves 22 (.Fgs 2 and 5) to receive the tongue 21 upon book section. The body of the tie rod 14 lies Within a groove 23 (Figs. 2 end 6) formed in the bottom of each book section and the top section. Every two adjacent sections cl a stock are secured together, in this instance, by means com.- prising a stud 24L seated in an opening in the upper end of each end 2 of each book section and in each end of the base section. The stud 24.- may be secured. in place in any suitable Way, as, for example, byineens of a screw 25 seated in the section and pissing through on opening in said stud. Each book section and the top section has in its lower side openings 26 to receive the studs 24 of e book section or the base section. The superposed section is secured to the sect-ion next below it by scrcn-"s 5-27 or equivalcntv devices entering openings 'i' the studs 01 said last mentioned section.

As shown in Fig. Q), the means tor alining the lowermost book section with the base section is it slight nu wliliczttion oi" the joint between two znljaecnt hook sections. lin stead of a long tongue 21 a shorter tongue 22'; is provided to lie Within the groove 11, and a stud 30 upon the base section is adapted to enter the groove 23. The door Ill oi catch. book section is pivotally mounted to swing forward and upward into a horizontal plane, andcis arranged to be pushed back into the upper part of the section. In the present construction, the onus of the door and the stop for the outward inm'enveut of be t lower ed es thereof are rebbeted at 532 (l igs.

.1 and 10 to lie within a rabbct 253 (l igs. l? and 12) lorined in t ne bottom and ends ol' the section. Upon theinner ol the ends 2, and near the upper edges of said ends, are formed shoulders 34: upon which the door is adapted to slide when pushed rcninartlly into the section. I I

The means for pivotally inonntin the door and for causing it to move in a strniglit line comprises a shalt 35 the ends ol' which are )ivotally mounted in bayonet slots it l'ormed in the inner faces of the ends 2, the open ends of said slots "lacing forward so that said. shalt may be withdrawn from its lie-rings in said slots by an upu'ard and l'm'nxard movement the shzr-l't: "U pen the i nner fare of the door and near the upper edge then are fixed two hooks 3'? adopted to on shaft 35 for )iv'otelly supporting tht upon said shalt. Upon each end of the shall 35 is fixeda roller 35 around which is wrapped one or more times a cord or sinn'nr device 35'), both ends of said cord being tired to the door, as for example, at 40 and 41. in this instance, the ,roller is ])(-n'ipl1()1'z|ll grooved as shown in Fi s. 10 and 'i l. The inner lace of the door has grooves 42 therein to :Hfi'iUlllmodnte the rollers 38. The lmoln 3? form n.

the-inwznd movement ol' the door he l l l r l l l j l l l l l l sheet metal stain of the shaft 35 out of the slots 36.

In operation, the door, when raised to a horizontal position, may be pushed reart 'ardly into the section, the door sliding upon the shoulders or ways As the door is pushed inwardl the rollers 38 are co1npolled to rotate through the flexible connection between said rollers and the door, and being fixed upon the shelt,said rollers comel both ends of the door to move in or out at the same time and at the same speed. ll'ioven'ient of one end of the door ahead of the other end is thereby prevented, and bind inc ol' the door in the section obviated. jnceut sta ks ol' sections may be interlocked by the means shown in Figs. .3 and 14, said means comprising plates 44 lo *eted upon the outer sides oi the ends oi the book sections. Each plate carries a hook 45 and e lug.46. The hook upon one end of the book section turns in n. direction opposite to that in which the hook upon the other end of the section lnccs. iidjneent. sections .ina v', therefore, he interhicked by interengaging the hooks 45 as shown in.,l i, r. lb. Such interei'igageinent is attained by lowering one into position be hind the other. The hooks or tongues 45 prevent separating .uiovenient in a horizontal plant'- in one dirortim'i, and the lugs 4b prevent horizontal movement in a direction at right angles to the removed. when desired, by lifting the ends st nientimied direction. .llarh device ll, so, ill nniy be an integral hug. Each book section may be quickly and easily set up by merely intel-engaging the ends 2 with the bottornB, connecting said ends with the tie rod 14, slipping the Intel; 4 into the grooves 17 and lit, and placing the ends of the shalt 35 in the pockets or slots ll"). The tie rod 14 rigidly unites the ends :2. and the bottom 3, as the joints between said ends and bottom cannot open when the upper ends of said ends 2 are rigidly secured together. To connect two sectii'ins together it only necessary to set one upon the other and pass the screws 27 film nigh the struts i2 1.

l desire it to be 'urulers'tood that in the practical .nmnul'act ure oi" the above described devices i do not regard myself as limited to the precise construction herein set forth, in'asnnurh as inn-Hy do )arturos from said construction. may be .nmde Within the scope of the invention.
