To all whom it may concern:

Be it known that I, W. HORACE Scena, of th city of Baltimore, and State of Maryland, have invented a new and improved School-Desk; and I do hereby declare that the following is 'a full, clear, and exact description thereof, which lwill enable persons skilled in the art to make, construct, and use the same, reference being had to the accompanying drawings, which form a part of this specification, in which- Figure l is a perspective view of a set of desks and a rear seat, showing the combination of the desk and the folding curved seat.

Figure 2 is au inside view of the standards A A.

Figure 3 is an outside view of the standards A A.

Figure 4 is a sectional view of the desk and seat.

Figure 5 is a longitudinal view of the metallic rod x.

Figure 6 is an outside view of the curved levers m m.

Figure 7 is an inside view of the curved levers 'm m.

Figure 8 is a View of the upper side of the curved levers fmy m.. Y

Figure 9 is a sectional view voli' the cleatsi i, with their India-rubber covering o o.

4UFigure 10 is a tiansverse view of the India rubber o o on the cleats li My invention consists ot' a new and inproved folding curved seat for school-desks, and of its combination with the part-s of a desk already known, making 'a new combination. l

The standards A A are made of castiron, or other suit-able material.

Fig. 2 shows the construction of the standards A A, the grooves to yreceive the back B, the book-shelf E, and the iront F. lt also shows the checks c c, and the rests r rr.

The seat D is constructed upon' the curved levers m m, (figs. 6 and 7.)

These levers have grooves, divided into sections by the transverse bars n n u, to receive the ends of .the slats .z s,s s, which are secured iu their places by screws, rivets, or nails. v

The middle of the seab is supported by the curved hatten y, but this is not essential.

On the short arms of the levers m mf, there are cleats,

'-i t', fig. 9, shaped like the iustum of a cone, and attached to the levers at the smaller end.

These cleats are covered with or surrounded by the India rubber o o, iig. 10, or its equivalent.

The -seat D is attached to thestandards A Aby the metallic rod x, iig. 5, which passes 'directly through the standards A A, the levers m m, and the batten y.

The seat D tums upon the metallic rod x, and when in position for use, the cleats i 1'. bear against the checks c c, and when folded, the cleats 'come in contact the back of the desk.

The India rubber on the cleats -i gives elasticity to the seat, and prevents noise.

The sectional view of the desk and seat, g. 4, shows the construction and position of each part.

Theback B, the book-shelf E, the front F, and the ards A A by screws.

The desk may be made with lids to raise, or with a permanent top, as shown in the perspective View, iig. 1.

The curves of the back B and the seatD are made upon physiological principles, for the promotion of health and comfort.

The folding seat affords great facilities for cleaning the schoolroom,'for the movements of teachers and pupils., and for gymnastic exercises.
