Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. Only the patent drawing is available. This patent is in the database for reference only.
“Stout truck-wheels are made to turn on strong axes. The front axes have two diverging pieces mortised into it, so as to stand out like hounds. The ends of these hounds are connected together by a curved piece of timber, a hole in the axle being the centre of the curve; through which hole the king bolt passes, which is to confine a piece of timber that is to operate as a tongue; the tongue may be bolted to any part of the curved piece which connects the hounds, so that it may stand either straight out, or obliquely, from the axle, to determine the direction of the wheels. By this tongue, or saddle-sill, the draft is to be made. Mortises are also made in the truck-wheels, to move them on, if required, by means of a new application of the lever to the wheels, which, however, is not described, unless the following was intended as a description of this new application. Into low carriage wheels, consisting of four or more pairs, mortises are made in any convenient number, to admit the ends of levers, (or handspikes,) and the carriage, (with the building on it) is moved by the successive application of these levers."
