lMliROVEMENT IN SCHOOL-DESKS ND CHAIRS.

The Schedule referred to in these Letters Patent and making part of the same.

I, ALEXANDER SIDNEY VAUGHAN, of Elkton, county of Cecil, State of Maryland, have invented a Combined School-Desk and Chair, of which the following is a specification.

Nature and Object of the Invention.

Description of the Accompanying Drawing.

Figure 1 is a perspective View of my combined school-:desk and chair;

Figure 2, a sectional view of the same; and

Figure 3 a detached view of part of iig. 2 drawn to un enlarged scale.

General Description The desk A rests upon and is secured to cast-iron' side frames B B', each of which has au extension, a, for the support of la hinged seat, D, for the occupant of the next desk in front.

In desks of this class, as heretofore constructed, the front piece b has been made to serve as a back for the seat thus secured to the frame of the desk; but as this front piece is comparatively narrow, and arranged vertically or nearly so, and at a considerable distancev above the seat, it iords but an iusuflcient and uncomfoitable back for the latter-an objection which Iiiave overcome by attaching a back, F, as well as a seat, to the supporting-framesof the desk.

This back, to which a proper curve and inclination' is given, may be secured to the side frames in any suitable manner, or be cast in one 'piece with the same. It is supported, in the present instance, at about thecenter,'by braces c c of the side frames.`

forming part of said frames, as specified.

The seat D consists of a light open metal frame, curved or beveled on its inside edge, as best observed in iig. 3, so as to forni a ledge, g, for the support of a plain board or of an upholstered seat, as may be desired.

The seat is hinged or pivoted in the usual manner at the points i i to the extensions of the side frames, so that it may he turned upward out ofthe way when it is desired to pass between the desks.

Two lugs, j j, on each of the side frames and on both sides ot' each pivoti, support the seat'in a horizontal position when it is turned downward, without permitting any strain upon the pivots, the tendencyv of the latter to become bent or broken, owing to the undue strain to lwhich they are subjected when but a singlelug is employed upon each side frame, as usual, t heilig thus avoided. f

In order'to avoid the noise caused by the striking of the seat upon Vthe lugs when it is suddenly lowered to .a' horizontal position, the Asaid lugs may be purtially hollowcd out to receive small blocks otgum-v elastic, or the seat itself may be faced on thel under side with gum-elastic, or with felt or other substance which will deaden the sound caused by the striking together of the metal surfaces. y

Claim.

The frames B B', supporting-the desk A and seat D, in combination with the back F secured to or In testimony whereof I have signed my name to this specification in the'presence of two subscribing witnesses. p
