i Letters Patent No. 63,795, dated April 16, 1867. I
IMPROVEMENT IN TABLE GUTLERY.

T ALL WHOM IT MAY CONGERN:
Be it known that I, WALTER HUBBARD, of Meriden, in the county of New Haven, and State of Connecticut, have invented a new and useful Manufacture, and that the following is a full, clear, and exact description thereof. My invention consists of a solid-handled cast-metal knife, or, 'in other words, of a knife-blade and handle cast in one piece with each other, such an article being produced at a low cost with all the advantages incident to the absence of any joint between the blade andhandle, and'when plated being superior to ordinary plated `knives in the respect that there is no joint between the blade and handle, and to solid-handled plated knife forged out of rolled metal, while it can be produced at a cost less than/that of either.
I construct my new articles by preference of cast iron, casting them in sand moulds in the manner practised in making small cast-iron articles. After they are taken from the moulds they are cleaned of the'sand and polished and sharpened by grinding them upon emery wheels. Then if the articles are to be sold With the blades bare the handles may be varnished or japanned by the usual process employed in japanning iron. If the articles are to be plated they are plated by preference with silver by the electrotype process, or they may be plated'with tin either by the electrotype process or bythe ordinary process of tinning iron articles by dipping them in a bath of melted tin. I do not deem it necessary to describe in detail all the operations required in silver-plating and in tinning, as they need not vary from those in use for plating other iron articles. Before the articles are' polished I prefer to improve their strength by subjecting them to the process by which cast-iron articles are converted into what is called malleable iron by the elimination of their carbon; or, the blades may have a steely natdre imparted to them by any means competent to that end. The form of the articles may be varied to suit the manufacturer, the two forms represented in the accompanying drawing at figs. 1 and 2 being examples of such forms as I have made with success.
Having thus described the several modes in which I have contemplated the application of the principle or characteristic by which my inventionmay be distinguished from others, I declare that I am aware that oyster knives have been forged out of steel so that the blade and handle are ineone piece, and that `small silver and plated German-silver knives have been made in the same manner by the action of dies or by hammering. I, however, believe that I am the first to discover the fact that a merchantable solid-handled knife with the blade and handlerin one piece can be formed by casting the metal directly into form, the result of which discovery is a great reduction in the cost of'manufacture and in the price at which the finished article can be furnished to the public. j
I do not, therefore, claim broadly to be the inventor of a solid-handled knife, either plain or plated, but what I claim as.' my invention, and desire to secure by Letters Patent, isv i The solid-handled c'ast-metal-knife herein described, the same being a new article of manufacture.
In testimony whereof I have hereto set my hand this twenty-fourth day of November, 1866.
WALTER HUBBARD.
