REVOLVING BOOK-CASE.

- SPECIFICATION forming part of Letters Patent No. 353,958, dated December 7, 1.886.

Application filed November 16, 1885. Serial No. T221310. (X model.)

T0 60% whom, 50' may concern:

Be it known that I, GEORGE V. NAUERTH, of Cincinnati, Hamilton county, Ohio, have invented new and useful Improvements in Revolving BooleCases, of which the following is a specification.

The class of revolving book-cases to which my invention relates is that illustrated by the subjectanatter of Patent No. 317,175, granted IO to me May 5, 1885.

The objects of my present invention are, first, toenable the guards shown in the above patent for retaining the books from endwise displacement on the shelves to also operate to r5 assist the quadruplex vertical partitions there in shown in supporting the shelves; second, to enable the book-rest on top of the case to be automatically retained at any angle to which it may be raised, and to be easily released when desired so as to allow it to fall into the horizontalposit ion, and also to enable such falling to take place without violent concussion against the case-top; and, third, by modifying the form of the aforesaid qnadruplex vertical partitions to adapt the case for holding pamphlets, periodicals, and other unbound matter in addition to bound books. To attain these several objects, the guards are provided with notches or recesses, which receive and 3c serveto support the edges of the shelves. The

hinged leaf of the book-rest is-provided with a prop, which is pivoted in the top of the case and is acted on by a spring, so that when the leaf is raised said prop is forced into engagenient behind one or other of a series of teeth on the bottom of said leaf. From such-err gagement it may be released by slightly lifting the leaf and then turning back the springprop, which is provided with a handle for that purpose, when the leaf may be allowed to fall 5 pneumatic cushion.

nected by two narrow boards, which form the other two sides of said well.

In the accompanying drawings, Figure l is aperspective view ofa revolving book-case embodying my invention. Fig. 2 is a vertical section. ofthe same on theline 2 2 in Fig. 3. Fig. 3 is a horizontal section on the line 3 3 in Fig. 2. Fig. 4 is an axial vertical section of the top part of the case. Fig. 5 is a top view without the bookrest leaf, part of the wood-work being broken away to expose the prop-spring. Fig. 6 is a perspective view of one of the quadruplex vertical partitions. Fig. 7 is a vertical, and Fig. 8 ahorizontal, section showing the mode of supporting the edge of the shelf in the notch of the guard. Fig. 9 is a perspective view of a notched or recessed portion of one of the guards. Fig. 10 isa representation to a reduced scale of any one of the shelves below the top one.

A represents a base or tripod, from which rises vertically a round post or standard, B, bearing on its top a socket, O, for a stud, D, that projects dmvnward from the uppermost of a series of shelves,boards, or floors, E E E, of which all below the top one, E, have a central orifice, c, for said post, and of which all have four smaller orifices, c, for as many tiebolts, hereinafter described. Interposed between said shelves are vertical partitions F, each partition being composed of four rectangular boards, of which two boards. f, are comparatively wide, and extend parallel to one another clear across the shelf, forming at their middle portions two walls of a square central well, L, and being connected by two narrow boards, f, which constitute the other walls of the said well. The space between any two shelves is thus divided into four compartments in addition to the square central well, L-namely, two narrow compartments, G, whose backs are constituted by the narrow boards f, and which are open in front and inclosed between the wide boards f, and two other compartments, G, whose backs are constituted by the boardsf, and which are open in front and also at the ends, except a partial closure at each end by an open metallic guard, H, preferably of the represented inverted U form, that occupies staples J in the edges of the intermediate shelf or shelves, E, and pits e in the upper suriace of the bottom shelf or floor, E.

tions and to prevent lateral as well as Nicks or notches h in the sides of the U formed metallic guards receive and support the contiguous edges of the intermediate shelf or shelves.

The shelves E E E and interposed partitions F are fastened rigidly together, so as to be supported and to be capable of turning as a whole on the stud G by means of four vertical rods or tie-bolts, K, which, traversing the holes 6 in the shelvesjust inside the four corners of the well L, are fastened and drawn taut by nuts M on their lower extremities, so as to hold all the parts of the revolving member immovably in their proper relative posivertical displacement of said parts.

It will be seen that each shelf, except the top and the bottom one, is not only supported by the vertical boards constituting the partitions, but is sustained at eight places in the notches of the metallic guards, which are thus made to su bserve a double purpose. The l oad is by this means distributed over the whole fabric and each shel f is compelled to coact with every other in mutual support. inclosures G, included between the wide hoards f, form convenient receptacles for magazines, pamphlets, and unbound matter generally.

- The described location of the tie-bolts K in the frame-work of the case insures their complete concealment by the well-walls and the leaf of the adjustable book-rest now to be de scribed.

Secured to the top of the uppermost shelf is a marginal bead, N, that formsa rectangular recess. 11, for a correspondingly-formed leaf, 0, which is at one edge-thereof secured by hinges Pto the said head. Upon the under surface of the leaf 0 is a rack, Q. which. when said leaf'is'lilted by its free edge, receives in one or other of its indentations a spring-prop, R, which constitutes a double crank or U-formed bend of an axle, 1', which occupies 'ournal-beariugs on the top shelf and is provided at one end with an arm, 'r', to which is attached one end of a spiral spring, S, whose other end is fastened to the top shelf, so as to give to the prop R atendeney to move in the direction of the arrow. The-other end of the axle r is prolonged beyond the top shelf and provided with a handle, 0"", for con- Venient manipulation of the propas, for example, when it'is desired to close or depress the leaf O the latter is sufficiently lifted with one hand to liberate the prop from the rack, while with the other hand upon the handle r the prop is lowered to the desired position and the leaf then suffered to drop into the corresponding position. If, on the contrary, it be desired to bring the leaf to a more ele- The narrow..

vated slope, it is merely necessary to elevate the'leaf to the desired position, and the spring of the prop automatically raises it to the corresponding position, so as to maintain the leaf in the new position. Should it be wished to bring the leaf to the horizontal or commay have any suitable projections, 0, which may serve the several purposes of. preventing a dictionary or other heavy book from slipping off the.said leaf, and of stops to prevent the leaf from being swung too far beyond th vertical'position.

I claim as new and of my invention 1. A revolving book-case body consisting of a bottom shelf, E, top shelf, E, intermediate shelf, E', interposed quad ruplex partitions F. eat-h formed of wide rectangular vertical boards], parallel to each other,extending from side to side of the body, and narrow vertical boards f between the wide boards forming wells L, and narrow compartments G, 'oolls K, by which the shelves and partitions are locked together; and the guards having recesses h, occupied by the contiguous edges of the intermediate shelf, substantially as set forth.

2. A revolving book-case body having a top, E, provided with a marginal bead, N, forming a recess. a, and a book-rest, O, having projections o, hinged by the upper corners of its lower edge to the upper rear edge of the bead and seating on the top within the recess, the bead fitting the rest closely, providing a pneumatic cushion for the rest, substantially as set forth.

3. A revolving book-case body having a top, a book-rest hinged to the top provided with a rack on the back thereof, a shaft formed with a double crank, arm, and handle constituting a prop that engages the rackteeth, and a spring pulling the arm of the.

shaft toward the rest when released, substantially as set forth.

In testimony of set my hand.
