1833. D. Redmund's 'Alpha' Steam Carriage.

In October, 1832, Mr. Redmund of City Road, patented a boiler, especially designed for locomotive sites. It consists of a series of parallel vertical chambers with corrugated sides, for the purpose of extending the heating surface, and accelerating the production of strain in a compact apparatus.

The principal difference between it and Mr. Hancock's, is in the circumstance of the corrugation. Mr. Redmund, shortly after the grant of his patent, constructed a very elegant steam carriage, which is represented in the subjoined cut. The wheels, it will be observed, are of a peculiar kind, and are, we are informed, the subject of a distinct patent; our space will not permit us here to describe them.

The arrangement and position of the chief part of the propelling mechanism is the same as Hancock's. The guiding is effected by reins in a similar manner to those of horses, each rein operating separately through the medium of levers in turning the fore wheels of the carriage to the right or left; and to facilitate this motion, each wheel revolves on a distinct axle supported in a frame that turns horizontally upon a pivot, after the manner of Ackerman's patent of 1816.
