IMPROVEMENT IN SEATS.

Specification forming part of Letters Patent No. 138,183, dated April 22, 1873; application tiled March 28, 1873.

To all whom it may concern:

Be it known that I, JOHN PEARD, of the city, county, and State of New York, have invented a new and useful Improvement in Seats; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which drawing- Figure l represents a sectional side view of my seat when unfolded. Fig. 2 is a side view of the same when folded. Fig. 3 is a plan or top view of the same when unfolded. Fig. 4 is a side view of the same when unfolded and adjusted for reading purposes.

Similar letters of reference indicate corresponding parts.

This invention consists in combining, with a hinged seat and with a hinged arm-piece, a brace and a link and a swivel disk, the brace and link being provided with stops in such a manner that the seat and arm-piece can be folded and unfolded with equal facility, either by taking hold of the arm-piece or by taking hold of the seat, and that during the operation of folding or unfolding the seat and arm-piece the binding of any part of the mechanism is effectually prevented 5 further, in a secondary brace connected to the main brace, which serves to adjust the desk forreading purposes.

In the drawing, the letter A designates a seat, which is connected to the frameB by means of hinge-joints, so that it can be folded up to the position shown in Fig. 2, or that it can be turned down to the position shown in Figs. 1, 3, and 4. To the outer end of this seat is secured a brace7 C, by means of a hinge-joint, a; and this brace connects, by a link, b, with the arm-piece D, that is hinged to the back F, so that it can swing up or down. The link b is connected to the brace (l by means of a pivot, c, and to the armpiece D by means of a pivot, d, which has its bearings in a bracket, c. On this bracket is formed a stop, j, which, when the seat and arm-piece are folded up, retains said link in the position shown in Fig. 2 5 and fromV the brace C projects a stop, g, which, when the seat and arm-piece are to be folded, bears on the lower edge of the link and compels the same to swing upward. By the action ofthese stops, in combination with the brace O and the link b, I am enabled to fold or unfold the seat A and armpiece D either by taking hold of the arm-piece or by taking hold of the seat, and the parts forming the connection between the seat and the armpiece are not liable to bind during the operation of folding or unfolding; and consequently these operations can be elfected at all times without difficulty and without the liability of straining or breaking any part of the seat..

In practice, the seat will be provided with two arm-pieces, though only one is shown in the drawing. With the arm-piece D is combined a desk, E, which is connected to said arm-piece by means of a pivot, h, and this pivot is made in the form of a clampingscrew, so that it serves to fasten the desk in the desired position, andthat it allows of removing the desk with ease and facility. By means of its pivot hmy desk can be turned out to the position shown in Figs. 1 and 3, or it can be swung in over the arm -V piece. When the desk is turned out it forms a convenient support for writing or reading, and in writing the arm-piece D supports the arm of the writer.

When the desk is to be used for reading purposes it may be provided with a strip to prevent the book from sliding down. and said strip can be so arranged that it will fold in so that it is out of the way if the4 desk is to be used for writing purposes.

My swivel-desk may be connected to a rigid arm-piece or to a folding arm-piece, and if the folding arm-piece is attached to the seat by a brace and link, as shown in Figs. l, 2, and 4 of the drawing, an additional brace, t', will be applied for the purpose of raising the front end of the arm-piece together with the desk as far as the link b will permit, (see Fig. 4.,) and by these means the book resting on the desk can be brought in a convenient position for the person occupying the seat.

It will be easily seen that this additional brace may be so arranged that it can be adjusted up or down, so that the position of the desk can be regulated to suit persons of differ- 2.
