DISCLAIMERS ENTERED DURING THE YEAR 1851.

Crackers-Cutting.

Your petitioner, therefore, hereby enters his disclaimer to that part of the claim in the said last-named specification which is in the following words, to wit:

"What I claim as my invention, and desire to secure by letters patent, is cutting, by means of reciprocating cutters, on an apron having an intermittent motion, substantially as described, by combining and connecting together, in the manner substantially as herein described, the reciprocating motion of the cutters with the intermitting progressive motion. of the apron that carries the dough to and under the cutters, to be delivered as described, whereby the apron moves the dough forward the required distance while the cutters are up, and remains at rest while they are cutting and leaving the dough."

Your petitioner further represents, that at the expiration of the said letters patent he was the owner of all the rights thereunder for making the machines therein described throughout the United States, but that he had sold several of such machines, together with the right to use the same, to different persons in various parts of the United States; and this disclaimer is to operate to the extent of the interest in said letters patent vested in your petitioner at the time of the expiration thereof, your petitioner having paid $10 into the treasury of the United States, agreeably to the requirements of the acts of Congress in that case made and provided. WILLIAM R. NEVINS.

Heddles-Wire Machinery for making.

The subscriber further represents that he is the sole and exclusive owner of the said letters patent, and of the right, interest, and property therein and thereby secured; and although he did not intend, in or by the specifications and drawings upon and in reference to which said letters patent were issued, (and of which copies are annexed to and form a part of said letters patent,) to represent or claim that he was the original or first inventor of the wheel, collar, or flange, with a sliding tooth and pulley, and treadle, or other device hereinafter particularly mentioned, or of any part thereof; and he insists that said specifications and drawings do not, when rightly understood, represent or claim that he was such inventor; and he also insists that said letters patent do not, when rightly understood, assume to confer on him any right as the supposed, assumed, or alleged inventor thereof, or of any part thereof; yet, in order to guard against any mistake or misconstruction in these respects, the subscriber

states:

(1.) That he did not mean to assert, claim, or represent, in and by said specifications or drawings, that he was the original or first inventor of the wheel mentioned as wheel fig. 8, in said specifications and drawings.

(2.) Nor did he mean to assert, claim, or represent, in and by said specifications or drawings, that he was the inventor of the collar or flange,

with a sliding tooth, which are partially represented on the drawing, fig 1, near letter Q, and also partially represented on the drawing, fig. 2, at that end of the cylinder where the receiving and discharging hook rod shows the hook, and near letter B.

(3.) Nor did he mean to assert, claim, or represent, in and by said specifications or drawings, that he was the inventor of the cord, pulley, or treadle partially represented on the drawing, figure 1, which cord, as there shown, extends from said pulley, near letter C, to said treadle. (4) Nor did he design, or intend by said specifications or drawings to claim, assert, or represent, that his invention would make a heddle, with a slack twist, in the half or part thereof which is towards the end where the wire is doubled.

And the subscriber says, that if said specifications and drawings import or mean that any or either of the aforesaid things was, or were, in. vented by him, or that his invention, as claimed by him, would make a heddle with any such slack twist, as aforesaid, the same was, and were, by and through inadvertence, accident, and mistake, not being so designed or intended by him; and he hereby fully disclaims the several matters and things aforesaid, numbered above, (1,) (2,) (3,) (4,) each and every part thereof, under and pursuant to the seventh section of the act of Congress entitled "An act in addition to the act to promote the progress of science and useful arts," approved March 3, 1837, and under and pursuant to the law in such cases made and provided; insisting, however, as he does, that the same are not, nor is any part thereof, claimed in and by said specifications and drawings, or either of them, or embraced in said letters patent; this disclaimer being made for greater caution, and to guard against misconstruction and mistakes in regard to such matters. A. J. WILLIAMS.

PAPERS AND ABSTRACTS

RELATING TO

EARLY AMERICAN INVENTIONS.

FROM THE ARCHIVES OF THE STATES.

No returns have been received under this head during the past year. This is to be regretted, as there is reason to believe much interesting matter still remains unexplored in State and municipal documents, and in the collections of societies and of individuals. With the view of reminding statesmen, historical and archæological societies, and citizens at large, of the importance of embodying the desired information in the Reports of this Office, for the use of future historians of the arts, their attention is again invited to the Circulars issued on the subject, the one marked [A] to Governors of States and Territories, and [B] to members of Congress.

[A.]

UNITED STATES PATENT OFFICE.

SIR: Endeavoring to trace up the history of American inventions as a duty appertaining to this Bureau, and supposing that interesting facts may lie hidden in the archives of the various States, particularly in the records of patents, of which some are known to have been granted under colonial rule, and others by more or less of the States, previous to their conceding the right to the general government, I respectfully request to be furnished with copies of any such documents as may be on file in the State Department of your State, the expense of which will be cheerfully borne by this Office.

It is well known that the application of machinery to many branches of art was begun, and has been brought to its present degree of perfection, almost solely by the ingenuity and labors of our countrymen. I need hardly instance the working of lumber, improvements in ploughs, the cut nail and card making mechanism; yet definite information respecting these and other inventions, while in their infancy, is entirely wanting.
