l. For a machine for Planing, Tonguing, and Grooving Plank, Boards., ~'c.; Wm. W. Woodworth, administrator of Win. W'ood- worth, deceased, July 8, 1845. This patent was originally granted oil the 27th of December, 1828:

before the expiration of the 14 years it was extended for 7 years, by the Board of' Commissioners instituted for this purpose, and subse- quently for seven years more by special act of Congress, in conside- ration of the great merits of the invention. As the validity of this patent has been fully sustained by the Supreme Court of the United States, at its last term, we insert the entire claim of the new patent.

Claim.-- ' , Having thus fully described lhc parts and combinations of parts and operation of the machine for planing, tonguing, and grooving boards or planks, and shown various modes in which the same may be constructed and made fo operate without changing the principle or mode of' operation of the machine, what is claimed there- in as the invention of William Woodworth, decen~ed, i~ the employ- ment of rotating planes, substantially as herein described, in combi- nation with rollers, or any analogous device, to prevent the boards from being drawn up by the planes when cutting upwards, or from the reduced, or planed, to the unplaned surface, as described.

- And, also, the combination of the rotating planes with the cutter- wheels for tonguing and grooving, for the purpose of planing, tonguing, and grooving boards, &c., at one operation, as described.

-And , also, the combination of either the tonguing or the grooving cutter-wheel tbr tonguing or grooving boards, 4.c., wi th the pressure rollers, as described ; the effect of the pressure rollers in these opera- tions being such as to keep the boards, &c., steady, and prevent t h e cutters from drawing the boards towards the centre of the cutter- wheels, whilst it is moved through by machinery in the planing ope- ration: the tendency of the plane is to lift the boards directly up against the rollers ; but in the tonguing and grooving, the tendency is overcome by the friction occasioned by the pressure of the rol- lers."

2. For machinery for manufacturing ¢lugers; Ezra L 'Hommedieu, Chester, Connecticut, July 30. This is the re-issue or" a patent granted to Ezra L 'Hommedieu and

R. A. Walrous, (the latter deceased,) on the 24th of July, 1898, and noticed in this Journal at page 20 of volume xxiv, second series, to which the reader is referred.

Notice (~ Invenlions clnd Improvements patenled by J'.~.~:s Boa-AR- ~)vs, Esq , New York.

In the last number of the Journal of the Franklin Institute, page 3:37, there is a notice of James Bogardus' Universal l~;ecentric Mill tbr Grinding, and, as Mr. B. is the inventor of many other valuable improvements, patented and unpatented, it may not be uninteresting to the readers of this Journal to give a brief notice of such o f his in- ventions as have been patented in this country.

The first patent granted to him was for improvements in clocks, on the 2d of March, 1830. The principle of this improvement consists in this, that the wheel which carries the hour hand, and the barrel for the chain, or cord, or main spring, turn on a common centre, and are combined with the two other wheels and three pinions, constructed with such relative proportions that the three hands which mark the hours, minutes, and seconds, shall be carried on three several axes by a weight or spring applied to the barrel, and a pendulum or balance applied to the seapement wheel in any-common form, so that the hands shall mark with precision their respective portions of time.

The second is for improvements in the striking part of clocks, ~ranted on the 18th of April, 1832. This improvement relates to the striking part of the clock, and consists in connecting the two barrels
