IETHOD OF MAKING HOUSEHOLD ARTICLES.

Application filed; January 15, 1926, Serial No. 81,581, and in Germany October 10, 1984.

My invention relates to a method of making household articles, such as spoons and forks, and it is an object of my invention to make such articles in as few operations as possible. To this end, instead of blanking the articles from plate, I forge them from round bars out to size and, in this manner, the articles are finished in substantially two operations instead of ten to twelve operations; as in the old method.

In the old method, a blank was punched from a plate of suitable metal or alloy, silver, German silver, etc., the size and configuration of such blank being adapted to those of the finished article. 'This blank was then cold-forged and cold-rolled, with re eated annealingsfuntil it had the desired con guration, and then cut out and polished.

As the material is diflicult to machine, and the finished article, spoon or fork, is of complicated configuration, this method is performed in many operations and is extremely difficult, besides requiring many tools and labour.

In the drawings, which form a part of this specification and wherein for the purpose of illustration is shown a preferred form of my invention,

Figure l is a view of the rod of copper alloy from which my process starts, and which is cut from the rod of material in what I designate as the first operation of my *method,

Figure 2 is a View of the blank after the '35 second operation when it has been flattened to form the bowl of the spoon,

F' re 3 is a plan view of the spoon after the t ird and last operation,

Figure 4 is an edge view thereof,

Figure 5 is a view of the blank rod representing the first operation of my fork making process,

igure '6 is a new of the blank after the second oppration when it has been flattened to form e prongs of the fork,

F e 7 is a plan view of the fork after the rd and last operation, and

Figure 8 is an edge View thereof.

In my novel method, the initial material is not plate but a, generally round bar of a suitable alloy. out from the bar and forged hot into the desired shape. This method comprises substantially only two operations viz, flattening out the round bar for the bow or the prongs, as the case may be, and forging the flattened portion into the finished shape. The bur is then removed and the article 18 ready for the finishing operations of pickling and polishmg.

In this manner, and by starting from a bar and forging hot, the same result. is achieved .in two operations as was achieved in ten to twelve operations in the old method.

Obviously, the manufacture is muchich'eap ened and the output is far superior as.-.compared with the old method. Any alloy which is suitable for hot. forg- Blanks of suitab e size are ing, may be used in connection with my novel method. Obviously, such alloys must possess the strength required and must not be attacked by acids and basic substances which are constituents of food.

High-class brass with a certain percentage of nickel is particularly suitable.

I claim:

- 1. Method of making spoons and forks, consisting in hot-forging from a bar the bowl or prong portion in one operation, and forging the remainder and finish-forging the portion already forged, in the next operation.

2. The method of making spoons and forks consisting in hot forging from a one-piece bar of copper alloy t e owl or pron portion in one operation, and forging t e remainder and finish forgingthe portion already forged in the nextoppration, the whole being accomplished with ut a; single heatmg.
