COLLAPSIBLE BOOKCASE.

Application med October 14, 1913.

T0 all whom t may concern.'

Be it known that 1, OLE C. MILLER, a citizen of the United States, residing at Chi'- cago, in the county of Cook and State of lllinois, have invented new and useful Improvements in Collapsible Bookcases, of which the following is a specification.

The invention relates to bookcases, and more particularly to the class of collapsible or sectional bookcases.

The primary object of the invention is the provision of a bookcase of this character wherein the sections thereof can be knocked down or set up for use without requiring the employment of fasteners such as nails, screws or the like.

Another object of the invention is the provision of a bookcase of this character wherein the hinged doors are mounted in a novel manner so as to prevent the binding thereof, thus permitting the opening and closing freely of the same, the guide tracks being constructed to prevent the pulling of the doors from the case when closing the same.

A further object of the invention is the provision of a bookcase wherein the parts constituting the independent compartments are fitted together in a novel manner so as to give rigidity to the case when set up, the doors being readily removable from the case without requiring the collapsing or disjointing of the parts thereof.

A still further object of the invention is the provision of a case of this character which is extremely simple in construction, readily and easily knocked down or set up, strong, durable, reliable and eiiicient in its purpose, and inexpensive in manufacture.

With these and other objects in View, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereunto appended.

1n the drawings z-Figure 1 is a vertical longitudinal sectional view through the case. Fig. 2 is a vertical transverse sectional view thereon. Fig. 3 is a view similar to Fig. 2, showing the door open. Fig. 4 is an edge elevation of one of the doors removed. Fig. 5 is a fragmentary perspective view of one of the end walls of one section of the case, showing the track for the door.

tom sections of the case removed therefrom. Fig. 7 is a fragmentary perspective view of the door, showing the bracket and roller thereon in detail.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, the case comprises a base A, sections B and C respectively, and a top D, the same being constructed and detachably connected together in a manner presently described.

The base A comprises spaced end pieces 10, formed with front and rear supporting legs 11 and 12 respectively. Arranged between the end pieces 10 at the front of the base is a front board 13, while supported upon the said end pieces 1() is a bottom 14 for the section B, thel said bottom and end pieces 10 being formed with interlocking tongues and grooves 16 and 17 for the fastening of the bottom to the said end pieces.

rlhe section B comprises end walls 18, a partition 19 which constitutes a shelf or bottom for the section C, and a back 20, the end walls 18 being connected to the bottom 14 and partition 19 through tongues and grooves 21 and 22 formed on and in the respective end walls and bottom and partition so that the said end walls and partition 19 can be detached from the base A should the occasion require. The back 2O is removably engaged in the grooves 23 formed in the inner faces of the end walls 18 and engages in a groove 24C in the under face of the partition 19 so as to retain the back in proper position for closing the rear side of the section B of the case. The section C is similarly constructed with respect to the section B, and comprises end walls 25, back 26, and top 27, the end walls 25 and the top 27 being connected through the medium of tongues and grooves 28 and 29 respectively, which are formed on and in the same. The back is removably fitted within the grooves 30 formed in the end walls 25, the top 27 and the partition 19.

Superimposed upon the section C is the top section D, which has its end pieces 31 detachably joined to the top 27 through the medium of tongues and grooves 33 and 3A respectively, while the back strip 35 of the top section D is engaged in a groove 36 formed in the top 27, The front board 37 of the top section D depends a distance to overlap the section C, the sections B and@ when set up being superimposed and are positioned upon the base section A, while the top section D rests upon the said section C.

Mounted in the inner faces of each end piece of thesections Band C is a track comprising a strip 38 having an upwardly and rearwardly bent forward end 39 forming a stop or abutment, theA said strip being engaged in the grooves 40 formed in the inner face ofthe end piece for the mounting of the same thereon, and adapted to travel upon these tracks formed bythe strips 38 are friction rollers 4:1 journaled upon L.- shaped brackets or hangers 42 secured to front door frames 43 to which are secured glass panels la as usual. The door frames when pulled outwardly willcause the rollers 41 to engage inthe abutment ends 39 of the tracks seas to prevent the pulling of the door frames from the sections B and C of the case'. The door frames 43 when closed will .engage bearing strips a5 fixed to the inner faces of the end walls of the sections B and C.

Y Fixed to the end walls of the sections B and C are'side strips 46, one end of each eX- tends beyond its respective end walls while its opposite end terminates spaced from the edge adjacent thereto of the end wall so that these strips 46 will overlap the end walls of adjacent sections of the case.V Itis to be understood of course that any number of sections forreceiving books may be added to increasethe capacity of the bookcase..

VIt will be noted that each door frame when in open position rests upon the forward ends 39 of the tracksV so that on the closing of the door section the same will be guided in its VVmovement by frictional contact with the ends 89 o-f the said tracks. It will be obvious that the construction of these tracks formed by the strips y38 is of great importance because by reason of the same the door is held more firmly in a position whereby it may slide backward and forward on the rollers ,in an easy manner.

Each bracket Ll2 has an extension l2 which is of greater area than the roller 4l so f as to extend beyond the periphery of the latter for engagement with the track and in this manner serves as a guide for the door when moved backward and forward on the said track. Thus it will be seen that by this mode of guiding the doors they will be prevented from binding during their movement.

From the foregoing it is thought that the construction and manner of operation of the device will be clearly understood, and therefore a more extended explanation has been omitted.

What is claimed is:-

In a cabinet, in combination, a pair of tracks secured upon the opposite side walls thereof, each of said tracks consisting of a longitudinal strip curved upwardly and rearwardly to form a loop, a door, a pair of L- shaped brackets each having one arm secured upon said door at opposite sides and edges but at the ends of the door, a roller journaled upon the other arm of each of said brackets and adapted to ride upon said brackets with the last named arms projecting below the strips and against the side edges of the latter, said brackets adapted to support said door at an inclination so that its forward end and weight may rest upon the loops of the tracks and make said loops serve as a fulcrum for lifting the rollers above the loopsof the tracks to release the door from the tracks.

In testimony whereof I afliX iny signature in presence of two witnesses.
