Description
Patented Apr. 22, 1924.
UNITED STATES EDGAR G. BEER, OF DETROIT, MICHIGAN.
- DRAWING COMPOUND.
Ho Brewing.
To all whom it may concern:
Be it known that I, EDGAR G. 13mm, a citizen of the United States, residing at Detroit, in the county of Wayne and State of' Michigan, have invented certain new and useful Improvements in Drawing Comounds, of which the following is a specication.
This discovery relates to a compound for W lubricating dies, rolls or other tools used in metal work. A substance of this kind is sometimes called a drawing compound. In the dies that are used for drawing sheet metal and stamping operations it is necessary to lubricate the metal and the dies by some substance that will stand up in the face of terrific pressures. The substance ordinarily used for this purpose is white lead and oil. White lead and oil is brushed or painted onto the sheet metal blank before it is put into the die. White lead, however, is extremely poisonous and is consequently very unhealthy for the operators of the machine. Furthermore, white lead is one of the heaviest substances known and is consequently relatively hard to handle in large quantities. It also becomes ingrained into the'pores of the metal and usually it has to be removed by the aid of some solvent, such as gasoline, turpentine or an acid or both.
It is the object of the present compound to afford a relatively harmless lubricant which has all the capacity to stand up in the face of heavy pressure that White lead has and yet is free from many of the objections attendant upon the use of white lead.
I find that the compound in which litho.
I find that it has substantially all the capacities of white lead in'resisting the high pressures.
Application filed September 16, 1921.
Serial Ho. 501,171.
The soap acts as a binder and thickener so that the lithopone will not settle out of the compound. The soap also acts as a lubricant, as does also the oil. The resin oil is not only a lubricant but it is very sticky, acting both as a binder for the ingredients of the compound and also serves to hold the compound from running oil the metal. The parafiin oil is not only a good lubricant but it acts as a carrier for the soap, lithopone and resin oil.
From the above description it will be evident that the use of lithopone in drawing compounds is the essential part of my discovery. It is not absolutely essential to use soap or the rosin oil; measurably good results can behad with the use of lithopone and a suitable lubricating oil. I find that parafiine oil is a suitable lubricating oil to act also as a carrier for the lithopone.
\Vhat I claim is:
1. A drawing compound for the purpose specified, consisting of lithopone and lubricating oil.
2. A drawing compound for the purpose specified, consisting of lithopone, lubricating oil and rosin oil.
3. A drawing compound for the purpose specified, consisting of lithopone, lubricating oil and soap.
4. A drawing compound for the purpose specified, consisting of lithopone, rosin oil, mineral oil and soap.
5. A drawing compound for the purpose specified, comprising lithopone, rosin oil, mineral oil, and a soap made of tallow and soda.
6. A drawing compound for the purpose specified, comprisil'm lithopone from 20 to 25%, soap from 15 to 20%, and lul'iricating oil.
7. A drawing compound for the purpose specified, comprising lithopone, 20 to 25%, soap. 1;; to 20",, and the remainder of oil divided into one-third rosin oil and twothirds parafiin lubricating oil.
In testimony whereof I afiix my signature.
EDGAR G. BEHR.
