T0 aZZ whom it may concern..-
Be it known that I, ARMAND MAUOHAIN, a citizen of the French Republic, residing at Geneva, Switzerland, have invented a new and useful Transformation School-Desk, with Movable Bench, of which the following is a specification.
In the accompanying drawings, Figure 1 shows the transformation desk with schoolbench disposed as a drawing-table for aged scholars. Fig. 2 shows the disposition of said desk with horizontal table and lifted seat to work standing. Fig. 3 shows the disposition. of the back of the seat permitting to regulate the depth of the scat according to the size of the scholar. Fig. 4 shows the desk provided with an etagcrc. Fig. 5 shows a cut through X Y, representing the disposition of rollers T and U in view of facilitating the sliding of the bearings C O.
In all the figures the same letters refer to the same parts.
The standards A A of the desk are combined with a plank, 1), which may be inclined, serving as a foot-rest. These standards A A are provided on their insides with slides, in which slide the secondary standards 0 O, supporting the box D of the desk. The secondary standards O are provided with slits 0, through which pass the bolts cl, affixed in the. standards A. With the help of these bolts the secondary standardsC may be clamped at whatever height may be desired.
1 The box I) is closed on live sides and open on the front when the table Y of the desk is in a horizontal position. The box D is closed on all sides when the table Y is inclined to the greatest extent, as indicated in Fig. 1. The table Y of the desk, which may be employed as a drawing-board, is connected at the ends ofthe box D by means of flanges E, secured to the ends of the boxD by pivot-screws. The inkstand G may be removed when the table Y is turned down flat. The table Y and the end flanges, E, may be swung upon the pivots into a greater or less inclined position.
The pivot pins or screws are placed in such a manner that the tablcY will swing forwardly and downwardly automatically, and thereby close or cover the box; D.
To provide for fixing the table Y of the desk either in the horizontal position represented in Fig. 2 or in a position less inclined than that shown by Fig. 1, the flanges E are providcd with eccentric prolongations E, formed as an arc of a circle, against which the bolt h is forced by the handle i.
According to the position of the hole into which the bolt It may pass the table of the desk will occupya more or less inclined position. It will always be possible to swing the. tabletop t into a horizontal position to take somcthing out of the box.
The construction 01: the flange F. may be such as shown in Fig. 1.
To facilitate the raising and lowering of the desk, the same is provided with a screw, l, supporting the box D and provided with nut, restingupon the top ofthc hollow pos .T. Upon turning the nut I, after having loos cued the bolts (1 d, the desk is raised to the desired height, in which it is then fastened by means of said bolts d d.
The screw ll, with nut 1' and hollow post J, may be a fixture with the desk,or they may be movable. ll removable, the same screw may be used for several desks.
All the parts of the described desk may be made of wood or of metal and formed more or less elegantly.
The movable seat is composed of two bearings, K, connected together by a cross-bar, N, and by a board, L, in which there are two ranges of holes, Z, through which pass the bolts m of the seat M. The back 0 may be affixed in whatever height desired with the help of the screws 0, Fig. 1, which pass through slits 7c of the bearings K, or by means of the hooks o, as shown by dotted lines in Fig. 3.
The seat M is formed of two parts, the one of which, h may be raised as it is shown in Fig. 3. Thelatter shows that by a rational choice of the angle w the depth of the seat is always proportional to its height. \V hen the seat and the back are both in the highest position, the depth of the seat is a", and when seat and back are both fixed in the lowest position the depth of the seat is only y.
In cases in which the followingdescribed manner of affixing the feet of the seat in a variable distance to those of the desk is found too expensive, the angle 3 may be chosen in a manner as to cause the seat to approach to the desk when the same is afiixed lower, as it is shown by dotted lines in Fig. 3.
The foot-pieces of the seat are connected to those of the desk by means of the sliders Q.
I do not'elaim a seat in which there are bars sliding vertically in slotted legs and held by pins, and to which bars the seat is'eonnccted bylinks, as such a device is shown in German Patent No. 11,5-ll.
I am aware that desks and tables have been made to be inclined or raised or lowered, and that the seat has been adjustable nearer to or farther from the desk, and that seats have been variable in height.
I claim as my invention- 1. In combination with a tipping desk-top, Y, slotted standards a, standards A, bolts d, and plank or rest 13, the screw H, nut I, and post J beneath the desk,for raising or 1owering the same and, firmly supporting such desk in addition 'to the support from the standards, as set forth.
2. The combination, with the hinged seat M, the standards K, and cross-board L,having vertical rows of holes in the same, and the attaching-bolts m, for varying the height of the seat, substantially as set forth.
ARMAND MAUOHAIN.
