Improvements in or relating to Welding Compounds.
I, HENRY EBERDING, of No. 40, North York Street, in the City of Paterson,
County of Passaic, and State of New Jersey, U.S.A., Welding Compound Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
Heretofore iron has been ground by suitable machinery, and has been combined
with various other ingredients to form welding compounds.
By experiments it has been proven, that steel is far superior, when used in
combination with different ingredients, for such welding compounds, and especi-
ally when in a state of powder corresponding to a fineness of from 10 to 30 meshes
per inch.
Steel filings to a certain extent, furnish when thoroughly combined with other
ingredients welding compounds giving some satisfaction, but the production of
said filings is slow and expensive and more over a certain percentage of the carbon
is used up during the process of filing; furthermore filings can only be produced
from larger pieces of steel.
The object of my present invention is to utilize waste of steel, which up to the
present time is of no commercial value whatsoever, and to produce from said waste
of steel an ingredient for the manufacture of welding compounds, for which
purpose the said waste of steel is ground, crushed, pounded etc. to a fineness of
from 10 to 30 meshes per inch.
To carry my invention into effect, I take scraps, or turnings or chips or any
waste of steel and place the same into a grinding mill of any well known con-
struction, but I want it understood that pounders, rolling mills, crushers, etc., can
be used without deviating from my invention.
The scraps, chips, etc., are then ground to the fineness required-as above stated,
and are afterwards-if so desired sifted through suitable sieves, nettings or bolting
cloths.
The ground steel so obtained contains sufficient carbon, that when compounded
with other ingredients to form a welding compound, it will not withdraw any
carbon from the steel pieces to be welded together, and thus produces a strong and
indestructible joint.
From the above it is obvious, that by using steel granules of the dimensions
stated and prepared in the manner described, a difficulty in the prior compounds
has been obviated.

I, HENRY EBERDING, of No. 40, North York Street, in the City of Paterson,
County of Passaic, and State of New Jersey, U.S.A., Welding Compound Manu-
facturer, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement: -
The object of my present invention is to reduce waste of steel, such as scraps,
turnings, chips, etc., to a fineness suitable for the manufacture of welding com-
pounds, by thoroughly grinding, pounding, or crushing the said waste of steel,
to thus prevent the with-drawing or using up of the carbon contained in the said
steel waste during the process of reducing the same; it is essential to retain as
much carbon as possible in the steel for reasons hereinafter stated.
Heretofore iron has been ground by suitable machinery, and has been combined
with various other ingredients to form welding compounds.
By experiments it has been proven, that steel is far superior, when used in
combination with different ingredients, for such welding compounds, and especi-
ally when in a state of powder corresponding to a fineness of from 10 to 30 meshes
per inch.
Steel filings to a certain extent, furnish when thoroughly combined with other
ingredients welding compounds giving some satisfaction, but the production of
said filings is slow and expensive and more over a certain percentage of the carbon
is used up during the process of filing; furthermore filings can only be produced
from larger pieces of steel, whilst for grinding, crushing, pounding, etc., waste of
steel can be used, and this is very important, as the waste up to the present time
is of no commercial value as it cannot be melted into ingots or other forms suitable
for the trade.
To carry my invention into effect I take scraps, or turnings or chips or any
waste of steel and place the same into a grinding mill of any well known con-
struction, but I want it understood that pounders, rolling mills, crushers, etc., can
be used without deviating from my invention.
The scraps, chips etc., are then ground to the fineness required-as above stated,
and are afterwards if so desired sifted through suitable sieves, nettings or
bolting cloths.
The ground steel so obtained contains sufficient carbon, that when compounded
with other ingredients to form a welding compound, it will not withdraw any
carbon from the steel pieces to be welded together, and thus produces a strong and
indestructible joint.
The ingredients as a preferred composition are as follows:-
Ground, powdered or crushed steel-one part.
Borax, one part.
Ashes, such as wood ashes one part.
From the above it is obvious, that by using steel granules of the dimensions
stated and prepared in the manner described, a difficulty in the prior compounds
has been obviated.
Having now particularly described and ascertained the nature of my said.
invention, and in what manner the same is to be performed, I declare that what
I claim, is:-
11
of the indiants of which is around nodorod

thirty meshes per inch.
2. The welding compound substantially as fully described in the above speci-
fication for the purpose specified.
