l WITNESSES: INVENTOR 1/7 WWW-W i9 galplz flake!" ATTORNEY Patented Apr. 14, 1925 UNITED y 1,53 ATENT ELECTRIC MANUFACTURING COMPANY,

A CORPORATION OF PENNSYLVANIA.

\ METHOD OF MAKING DECORATIVE ARTICLES.

Application filed November 12, 1920. Serial No. 423,647..

To all whom it may concern: Be it known that I, RALPH BAKER, a citizen of the United States, and'a resident of 'Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Methods of Making Decorative Articles, of which the following is. a specification. p

This invention relates to ornamental arc welding, more especially to utilizing an electric are, such as is ordinarily employed for electric welding, for the formation of deposits to produce receptacles or containers of ornamental and useful shapes.

I have found that metal derived from a fusible metal electrode by the passage of a current therethr'ough may be so deposited in superposed layers as to form various articles of an ornamental and useful nature, it being among the objects of my invention to produce such objects of various designs.

Another object of my invention is to construct walls of receptacles or containers by manipulating a fusible electrode helically to form superposed deposits of metal;

A further object of my invention is to provide mechanlcal control means for manipulating an electrode to obtain predetermined, uniform deposits of metal.

In practising my invention, I generally provide a non-adherent base plate on which the metal is deposited by an arc formed between the base plate and a fusible metal electrode. Thecurrent used is of such magnitude as is consistent with the speed at which the electrode is manipulated and the thickness of the deposit desired, the current value. usually varying from 5,000 to 10,000 amperes per square inch.

In the accompanying drawings which illustrate several embodiments of my invention,

Fig. 1 is a view, in perspective, of an article formed on a metal plate, and con-.

sisting of superposed layers of metal deposited thereon in accordance with my in vention; V

Fig. 2 is a similar view of an article of somewhat different structure;

Fig. 3 is an elevational view of a wall section showing a sequence of deposits formed in accordance. with my invention.

In order td form receptacles or other objects by my method, I provide a fusible electrode of metal placed in a suitable welding circuit. In accordance with this invention, any suitable motion may be given to the electrode to form various configurations built up of superposed layers of metal deposits to form containers.

To form an integral structure, I utilize a non-fusible base plate, and, by manipulating the electrode to form an endless spiral deposit having a lead equal to the. width of the deposit, I form the base or bottom of a container. In forming the side walls, I manipulate the electrode in a circular manner, forming a continuous heli'x of deposited metal having a lead equal to the depth of the of the deposit.

In forming a complete container from deposited metal, I generally utilize a metal base plate of a high thermal conductivity and capacity which rapidly diffuses the heat of the are, thus preventing fusion of the metal deposits to the plate. In some instances, I may utilize a base plate of low thermal capacity or of the same metal as the fusible electrode and allow the deposited metal to adhere thereto to form an integral part thereof.

I establish an are between a fusible metal electrode and a base plate 1 to form a deposit 2 of the desired shape or outline, either round, as shown in Fig. 1, or elliptical, as shown in Fig. 2, or of any suitable contour. By manipulating the electrode to follow the same outline as deposit 2 over and over again, I obtain an endless deposit forming superposed layers 3, 4, 5, 6, 7, 8, etc., constituting the walls of the container. A double or extra heavy deposit 9 may be formed as the top layer of theconta-iner, and handles 10 may be formed on the body, as shown, by superposing deposits in a suitable manner.

I need not necessarily manipulate the electrode by hand. If the electrode is to be manipulated to form a number of articles having like contour, pantographic or other apparatus, such as is used by engravers, may be employed. This invention allows a wide latitude of design and manipulation. 1 The superposed deposits may be combined into any one of a large. num er of designs, patterns, objects of art, utensils, imitations of objects. trimmings for objects, etc.

It is to be understood that, although I have described my invention as including the use of a metallic-electrode weldi'ng arc, it is not limited to the use thereof, but other means for depositing molten metals, in a manner similar to that described, may be used. For instance, a carbon arc may be used in combination with a fusible. metal rod or bar.

I claim as my invention:

1. A method of forming metal deposits into receptacles which comprises establishing an are between a fusible electrode and a metal base, and manipulating said electrode to produce superposed deposits to form the walls of a receptacle.

2. A method of depositing metal which comprises establishing an are between a fusible electrode and a metal base, and manipulating said are on said base to form an endless helix of superposed deposits.

Lteaaoo 3. A method of depositing metal which comprises establishing an are between a fusible metal electrode and a non-adherent metal base plate, manipulating said are spirally to form contiguous layers, and forming an endless helix of superposed deposits thereon.

4. A receptacle comprising superposed layers of fused metal. v

5. A receptacle comprising a spiral deposit of fused metal forming a base of contiguous layers, and superposed layers of fused metal forming the walls thereof.

6. A receptacle comprising contiguous and superposed deposits of fused metal having projections I deposited thereon.

In testimony whereof, I have hereunto subscribed my name this 3rd day of N ovemher, 1920.

RALPH BAKER.
