CHARLES STREIT, OF CINCINNATI, OHIO.
IMPROVEMENT IN XTENSION-LOUNGES.
Specification forming part of Letters Patent No. 147,447, dated February 10, 1874,' application tiled March 20, 1873.
To all whom it may concern:
Be it known that I, CHARLES STRE1T,of Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Extension-Lounges, of which the following is a specification:
My invention relates to the class ot exten-l sion-lounges having three principal parts, to Wit, the stationary frame, the sinking frame to rise and fall in the stationary frame, and the sliding frame to close over the sinking frame when the lounge is shut up; and my invention consists of a peculiar combination of devices or instrumentalities for raising and lowering' the sinking frame, by which the sinking frame is lifted and depressed bodily. The
" mechanism for accomplishing this is furthermore so arranged that the vertical motions of the sinking frame are eEected Without any tendency to move it endwise.
Figure l is a longitudinal section of my improved lounge when closed up, with the sink ing frame necessarily depressed. Fig. 2 is a longitudinal section of the same extended, and the sinking frame raised to a level with the sliding frame. Fig. 3 is a cross-section of the lounge through line X X. Fig. 4 exhibits, in skeleton perspective, the lifting device for opera-ting the sinking frame.
Ais the stationary frame of the lounge, and B the sliding or extension frame, which is adapted to be fitted with the customary inattress or spring stuffing. C is the sinking frame, which is fitted to rise and fall so as to permit the extension part B to slide over it when the lounge is closed, and rise to a level with the part B when the lounge is opened I for a bed.
The part B is fitted with slides b, which rest and move upon the slides c of the frame A. In order that the sinking frame C may be conveniently raised and 10W- ered pcrpendicularly, and in such a Way as to have no tendency to move endwise in the act of raising or lowering, I provide the swinging litters D D', hinged to the frame A at cl d, and connected together to swing in opposite directions simultaneously by pitman E and cranks F F' on opposite sides of the fulcrums d d'. This is the most desirable way of disposing Ithe lifting mechanism; but my invention is not limited to this particular arrangement, as the cranks may be so disposed that the litters will swing in the same direction. To the crank F a lever, G, is attached, by which the litters D D' are operated. The shafts or swiveling projections cl, upon which the lifters are hinged to the frame A, are constructed and attached to the lifters D D' in the manner shown in Fig. 4. The shafts el at the crank ends pass through the frame A ofthe lounge, and the cranks F F' and pitman E are attached and operate at the back of the lounge, as shown in dotted lines in Figs. l and 2.
I claim- The combination of the sinking frame C, lifters D D', cranks F F', and connecting-pitman E, substantially as and for the purpose specified.
In testimony of which invention I hereunto set my hand.
