SPECIFICATION forming part of Letters Patent No. 497,657, dated May 16, 1893.`

Application filed August 8, 1892. Serial No.442A57. (No model.)

To all whom, it may concern.-

Be it known that l, FRED H. HALEY, a citivzen of the United States, residing at Hamil- This invention relates to the construction.

of revolving cases employed for exhibiting or storing books or other articles, and it embodies features pertaining to the bearings in and upon which the case rotates, and also the construction ofthe case which adaptsit to be put together without glue joints, whereby it is suited for shipment in a knock down condition, and adapted particularly to transportation for long distances and to points where the services of expert mechanics or finishers are not obtainable, since all the parts may be completely finished before shipment and assembled without disgurement and Without the necessity of skilled mechanical labor. w

Fig. 13 is aperspective of a metal shelf support which is let into the sides. Fig. 14 is van enlarged detail plan of a clip which is fastened to the shelves to co-operate with the shelf support shown in Fig. 13.

I will first describe so much of myv invention as relates to the devices for supporting and permitting the rotation of the case upon the base.

A is aplank constituting a fixed base, which may be provided with customary casters A.

B is a metal spider or frame which is fastened by screws to the upper side of the base plank A. At the center of the spider B, its hub B hasv the square socket B10, in which rests the pivot blockBZ, which has the conical seat B20, adapted to receive the conical terminal of the spindle hereinafter described which pertains to the revolving case.

B3 is a thumb screw, which is screwed up into the hub from the lower side yat the center of the socket B10, and is designed to adjust the pivot block B2 in height fora purpose hereinafter explained.

B4 is a groove in the upper face of the spider B, concentric with the conical socket in the .pivot block B2, which is designed to serve -as a track for the anti-friction rollers hereinafter described.

C is a frame or spider which is secured to the under side of the plank c', which directly supports the case, and might be the bottom cap thereof. This spider has at its center IOC the hub C', terminating downwardly in a spindle C10, whose conical point seats in the conical socket B20 of the pivot block B2. The length of the spindle C10 is such that when the conical point is seated in the pivot block, the lower face of the spider C is separated from the upper face of the spider B a sufficient distance to admit between them the annular frame D, with its anti-friction rollers D D', &c. These rollers find a track in the groove B4 in the lower spider B, and a similar track in the similar groove C1 in the lower face of the spider C, said tracks C4 and B4 facing each other.

The annular frame D comprises inner and outer rings connected by cross ties d at intervals in the circumference. Preferably, this annular frame is cast with the inner and outer rings and the crossties integral. The antifriction rollers CZ of any desired number are placed between the inner and outer ringsin the intervals between the cross-ties d, inserted through them after they are in position and suitably secured. The lower spider B has a peripheral flange B2, and to the upper spider C are secured a plurality of brackets C2, which project downward past the flanges B5, and are turned inward at their lower ends so that they engage underneath the fiange and therebyT prevent the upper spider from being lifted olf the lower after it is suitably placed in position with the roller-bearing-frame intervening and the brackets properly adjusted and fastened.

When the parts are in position, as shown in Fig. 2, the thumb screw B3 Will be used to adjust the pivot block B2 high enough so that said pivot,- block and the spindle which seats in it take between them substantially the entire weight of the case, but not high enough to absolutely prevent contact of the spider C with the rollers D that is to say, when the weight is carried at the center on the spindle and its bearing the adjustment may be made so accurate that the rollers will still feel the contact of the upper spider upon them, and they will operate to steady the case and prevent it-s tilting over the support at the center. Thus I obtain the ease of rotary movement which is due to the center spindle bearing and at the same time equal steadiness and accuracy of position as if the weight were snpported at a distance from the center, as, for example, as it it were supported upon the rollers.

I am aware that it is not new to connect a rotary base to a fixed base by a center bolt and to interpose between them anti-friction rollers traveling in tracks concentric with such center bolt, and I do not claim broadly rollers in such relation to the fixed and rotary base. i

The second part of my invention relates to the construction of the case mounted upon this base, the features of which are such as to adapt it to be taken apart and re-assembled and the parts secured without the use of glue,

screws or nails, and so that none of the snrfaces which are exposed when the case is fully assembled are liable to be marred in the process ot' assembling or detaching.

E E are the upper and lower caps respectively of the case. The uprights F F, which extend between them, in whatever form they are arranged, according to the arrangement of shelving or other facilities in the casefare set in grooves E in the caps. By means of the upright sides G, the upper and lower caps are bound together to prevent them from being separated by a movement longitudinal with respect to the uprights F, by which said uprights might be dislodged from thegrooves in the caps. The devices which adapt the upright sides G to perform this function consist of terminal clips G at the lower ends of the sides, and clips H, secured to the base cap E. The terminal clips G are in any suitable manner arranged to be securely fastened to the ends of the sides G, and terminate each in a hook G10. The clips II are similarly adapted to be secured to the edge of the base cap E, and have a socket H', which the hook G10 is adapted to enter from above, and an aperture H10 into which the point of the hook is made to protrude by swinging vthe side G from an inclined position shown in dotted line in Fig. 7 toward the upright position which it will oc cupy when the case is completely assembled, as seen in full lines in said Fig. 7.

In order to secure the upper end of the side G to the upper cap E, a clip G2 is provided, adapted to be secured to the upper end ol' the side G, and a corresponding clip H2 is secured tothe upper cap. These clips have similar tongues H20 and G20, projecting respectively horizontally and vertically, and in lateral proximity to each other when the case is assembled.

In order that the top and bottom caps may not only be held against vertical separation, but may be drawn and tightly bound together and onto the uprights by means of the sides G, the tongues H20 of the clips H2, which are fastened onto the top cap, are each provided with a lateral shoulder H21, facing upward, which is inclined as shown in the drawings, being highest at the inner end, and the tongue G20 of the clip has a similar shoulder G21, facing downward, and corresponding in inclina tion to the upwardly facing shoulder H21, so that as the side G is swung in toward its upright position against the cap, the sloping shoulders G21 and H21, engaging` and sliding upon each other,tend to draw the cap tightly down onto the uprights, and by their engagement, without regard tomtheir slope, prevent the top and bottom caps from being separated vertically.

I prefer to make the shelves or horizontal partitions ot' the case serve as a means of holding the sides G up against the upper cap in the position in which, by the engagement of the shoulders G21 and H21, they serve to IOC IIO

hold the caps onto the uprights. And I accomplish this purpose, besides other purposes which pertain to the adj ustment of the shelves, by the following devices, comprising first, metal shelf supports K, which I prefer to cast integrally, comprising a base plate with angle hooks K projecting therefrom at intervals of an inch more or less throughout the length of the base. upon their inner surfaces, as at g2, deep enough to receive the shelf support K, to the full depth of the hooks K', so that said hooks do not project beyond the inner surfaces of said sides, as seen in Fig. 7. The shelf supports may be secured to tho sides in the grooves by screws through holes k at intervals in the length.

To the shelves L, at the ends, and, preferably,'let into the under side, as seen in Fig. 7, I secure the clips L', which have lugs L10 projecting beyond the ends of the shelves L, adapted to enter the grooves g2, and having the apertures Z10,adapted to receive the hooks K on the shelf supports. After the caps and uprights and sides are assembled Vas described, the shelves, provided with the clips L', being introduced between the upright sides, may be hooked to the shelf supports at all desired positions, leaving any desired interval between consecutive shelves, and being thus engaged with the hooks on the shelf supports, prevent thespreading of the sides which might occur through warping or springing, and which would tend to permit the shelves to drop down if they were only supported in the customary, manner in grooves, and at the same time, this connection of the shelves to the shelf supports prevents the sides from swinging outward at their upper ends, and becoming disengaged from the top caps, and thereby the shelves,-or, particularly, the top shelf,-be comes a key to lock the sides G to the top cap. In addition to this expedient, and in order to render the case secure even during the tentporary removal of the shelves or horizontal partitions, the tongues G20and H20 of the clips G2 and H2 are pro vided with apertures h20 and g20, respectively, which coincide when the side G is brought to its upright position, and a key-bolt M is inserted horizontally through them, binding them together.

The clips H2 and G2 may be applied only at the corners of the side G, and at corresponding positions on the top cap E, but, if preferred, additional similar clips may be applied between the corner clips, the cap beingl cut away to admit the tongue of the clip G2 alongside the tongue of the clip H2, and the wood of the cap being bored through in the line of the apertures Q20 h20, so that a single key bolt may be inserted across the whole width of the side G, and take through all the cli s.

lll; will be obvious that the form of connection of sides and caps herein shown at the top and bottom respectively, may each be The sides G are grooved used in either position, and that the form shown at the top may be used at both ends, if preferred. v

I claiml. In a case, in combination with horizontal and upright members making corner junctions, clips H2 and G2 adapted to be secured to said members respectively, and projecting from said members side by side'and provided with oppositely facing shoulders H21 and G21 which engage each other, said clips having the apertures h2o and 920, and the locking pin adapted to be inserted through them: substantially as set forth.
