UNITED STATES PATENT CEEICE.
ELEAZER CARVER, OF BRIDGEWATER MASSACHUSETTS.
IMPRovED vAR'lETY-coUcI-i.
Specification forming part of Letters Patent No. 775, dated J une 12, 1838.
To all whom it may concern :l
\ Be it known that I, ELEAZER CARVER, of Bridgewater, in the county of Plymouth and Commonwealth of Massachusetts, have invented an improved couch or easy-chair, for accommodation, health, and comfort, whichI denominate a varietycouch; 7 and I do hereby declare that the following is a full and exact description thereof.
Figure l in the accompanying drawings is a perspective View of the couch and of the frame in which it may be suspended when desired.' Fig. 2 represents the couch with one side of the lower part or stool removed for the purpose of exhibiting the arrangement of some parts of the machinery which could not otherwise be brought into sight.
In each of these gures like parts are designated by the same letters of reference.
A A is what I denominate the stool, which fhas four legs furnished with rollers or casters, and which serves as the basis by which the other parts of the couch are supported.
B is one side of the seat, which works upon a joint-pin at b, and to these side pieces are attached toothed segments C, into which a pinion, D, Fig. 2, gears, for the purpose of raising or lowering the seat. l
E, Fig. I, is a toothed wheel on the same shaft with the pinion D, and F is a ratchetwheel furnished with a spring-pawl, G, and carrying a pinion gearing into E. A winch adapted to the shaft of F will give the desired movement to the seat B. The back of the couch H turns upon the same j oint-pins b with the seat B. The arms 71l h also turn on joint-pins, asvshown in Fig. l, and in every position of the seat preserve their parallelism thereto.
The back of the couch may be placed at any degree of inclination which may be desired; or it may assume a vertical or horizontal position. To retain it in place I construct spring-bolts L L, `which are affixed to the sides H of the back, the ends of which bolts drop into notches in metallic circular segments K,prepared to receive them. Other arrangements may be eected, but this I have found to answer the best.
M is one of the side pieces of the front or leg support of the couch, attached to, B by joint-pins, and capable, like it, of having its inclination changed in any required degree.
For this purpose anotched segment-plate, N, is attached to the side pieces, B, of the seat,
and into them a catch pawl or lever, G, is adapted, said catch being attached to M, and being borne up by aspring.
l? is a foot stool or rest having hooked rods R R. to support it, and which may also be `used to alter its inclination.l This footstool is made to slide along the pieces M, to adapt it perfectly to the length of. the legs. This is eifected by means of a rack-and-pinion movement fixed in the ordinary way, S being one of the pinions.
T represents a ratchet-wheel and spring- `pawl for moving and holding the slide, and
operating in a manner toowell known to r`equire description. l l
In Fig. 1, W W represent a suspendingframe, and X X rods of metal, thelower` ends of which may be bent at right angles, and
enter holes adapted to receive them in the `.to beyadapted to this couch, or to speak of other known devices for the convenience of the person sitting or reclining thereon, as the means of employing them will be perfectly obvious.
I do not intend to claim as of my `invention the individual parts of this apparatus which I have described above, as, taken alone, most of Athem are familiarly known to machinists; but
What I do claim is The particular manner vin which the inclination ofthe back ofthe couch is governed by the spring-bolts and notched segments, as described, and the particular manner in which this is combined and connected with the other parts, so as toconstitnte a variety-couch, substantially like that set forth, taken in its combined character.
ELEAZER CARVER.
