l Specification of Letters Patent No. 8,800, dated March 16,4 1852.

To all whom 'it may concern:

Be it known that I, JOHN T. HAMMITT, of Philadelphia, in the county of Philadelphia and State `of Pennsylvania, have invented certain new and useful Improvement-s in Sofa-Bedsteads, and that the following is av full, clear, and exact description of the principle or character which distinguishes them from all other things before known and of the usual manner of making, modifying, and using the same, reference being had to the accompanying.drawing, which forms a part thereof. Y

My improvements are comprised in the combinations of certain conveniences for the toilet and other purposes necessary to a bed chamber, all contained within the dimensions 'of a sofa when put up and yet to be easily drawn out and arranged for service. The construction is as followsz-The main frame ofthe sofa-arms, &c., may be of any desired pattern, so that it is large enough for the purpose, and any ordinary dimensions will answer. At either end of the sofa is a box, made deeper at its back part than at the front, by which I att-ain all the necessary room and avoid a clumsy appearance. In addition to these, and behind the sofa a long draw (a) can'be drawn out, whichgwill hold theledclothes. At this point are supporters for the back of the sofa, which turns down to form the bed. Figure@ shows the `end view of the sofa, with the box (ZJ) and the table fixture drawn out. `This table is composed of two broad sliding pieces (c) that move into the box horizontally and are drawn out in forming a table. They are jointed so that when drawn out a proper distance the ends can be turned up into a perpendicular posit-ion, as shown in Figs. l and 2, where they are fastened by a catch, shown inudetail in Figq. Atthe outer end of these slides there is aplain board (el) that"frms-afwash standwhen turned up, and hinged tothe upper edge of this is anotherfinishedboard (e) which canbeturned up between the stand and the sofa arm to protect it when being used as a wash stand. l/Vhen this last named board (e) is turned down upon the wash stand a neat and convenient table is formed, and when the sup porters (c) are turned down horizontal these are brought into a perpendicular position, as shown by the dotted lines, and then by Vpushing in the slides the table top closes the box and forms a perfect finish at the end.

The box will contain the wash basin and ewer, towels, &c. The opposite box is closed by a door hinged at the bottom, that lets down to open it, and will contain the other conveniences required. The back is made and upholstered with springs, turns down on a pivot, and then is permitted to slide inward till `it meets the 'cushion of the seat. These slides are shown in detail in Fig. 4 and they permit the back to be readily removed to clean the sofa. i

Having thus fully described my improved sofa bedstead, what I claim therein as new, and for which I desire to secure Letters Patent, is-

1. The combining the back of the sofa with the seat, by means of sliding pivots in the manner and for the purpose set forth.

2. I also claim the sliding table and wash` stand, in combination with the sofa, substantially in the manner and for the purpose set forth.
