Patent For Improved Invalid-Chair
| |||||||||||||
|
||
| 49 | At the lower end of the foot-rest is a drop, P, which may be raised at pleasure, to meet the bottom of the feet, and is supported by the jointed braces f f. | |
| 50 | As will be seen by fig. 5, our socket-joints are circular hinges, attached and applied in such manner as not to be easily deranged. The two halves of the hinge are on the post and arm and the pin fastening them passes through the whole joint, so that no opening is made by moving the frame backward and forward. | |
| 51 | The same principle is shown in figs. 6 and 7, so that, by the socket-joints, no inconvenience is experienced in upholstering, and the joints are all covered, and the, chair worked with no show of open joints. | |
| 52 | When the chair is in use, the foot-rest E may be raised level with the seat, as shown in fig. 2 by red lines, and, by means of handles p p, the forward part may be raised, and the chair used as a carriage. | |
| 53 | Having thus fully described our chair, | |
| 54 | What we claim as new, and desire to secure by Letters Patent, is -- | |
| 55 | A chair, constructed with wheels m m, attached by means of springs XX, arms and back united by socket-joints S S S S, foot-rest E, drop P, cogged quadrants a a, shaft n, with cog-wheels F F, ratchet d, crank b, armed shaft j, springs h h, crank k, and notched joint g, as arranged, for the use and purpose as specified and herein set forth. | |
| 56 | In testimony whereof, we have signed our names to this specification, in the presence of two subscribing witnesses. | |
