Lathe Chuck
|
Simon Fairman |
Waterford, Saratoga County, NY |
The 1851 Rochester City Directory spells the patentee's name as Simeon Fairman, Sr.
The 1873 "Subject-matter index of patents for inventions issued by the United States Patent Office" says that this patent was extended to July, 1854.
Abstract:
The practical effect of the machine upon which my improvements are made, as applied to chucks to lathes, is to adapt them, in respect to size, to such articles as are subjected to the process of turning, and furnish an improved method of obtaining a center to the same as well as for securing them in the lathe for the purpose of being turned. Its application to pulleys is for the purpose of increasing or reducing the temper of their bands or for varying the speed of the band by applying the machine to the pulley which gives it motion or by a like application to that which receives motion from it, for rendering its revolution, under the same speed of band, more or less frequent or powerful.
Claim:
The method of securing together the front and back plates by means of the tubes and nut, by which I am enabled to attach the front plate directly to the mandrel or face plate, of the latter all as above described, in like manner.

"For a plan for Propelling Land Carriages by means of Steam; Simon Fairman, Nassau, Rensellaer County, New York, March 27.
The specification and drawings belonging to this patent have been prepared with much care, and occupy considerable space, as the structure of the carriage, the propelling machinery, and the steam engine, are all particularly exemplified. To make known these particulars would require the whole specification with its drawings. It is well known that in England several different engineers have been for some years engaged in endeavouring to effect the object for which the present patent is obtained, and that a carriage has actually run to a considerable distance on a common turnpike road, surmounting the ascents, and carrying considerable weight; still the invention is far from complete there, although more has been done than we formerly believed to be possible, and the practicability of running a carriage upon good roads has been demonstrated. We are of opinion that it would have been more prudent to wait for some further experiments at the expense of those who have the thing in hand there, than to commence here a similar career, which will undoubtedly cause the expenditure of large sums, as many abortive essays will be made before complete success is obtained; more good luck than usual must be experienced should not this be the case.
From our recollection of some parts of the carriages constructed in England, we are apprehensive that there are claims made by the present patentee, with which they will interfere; we also think some of the claims too broad, they are as follow.
The parts which I claim as composing the several items of this my improvement, are the platform with all the variations which may be necessary to adapt it to each and every kind of land carriage, together with all the superstructure herein specified; the hind wheels
and revolving axle, and all the intermediate machinery between them and the steam engine, together with the ratchets, the friction band, and expanding corks; the steam engine so far as it differs from those in common use, and the boiler and generator."
