T 0 qll'w'iwm it may concern.
elitnkriown that I, CARL Sonatina. a citizen jotGermany, residing at Berlin TegeljGermany. have invented certain new .iandfmseful Improvements in Processes of Manufacturing Antifriction Bearings and Compounds, of which the following is a specification.
lll'y process utilizes the cementing properties of chlormagnesialye, as well as its wood pulp dissolvingproperties for the manufacture of a magnesia cement of great sliding ability, suitable for the manufacture of sliding bodies or antifriction bearings,
.whi h can be used, if so desired, withoutlubrication.
Bearings have been recommended to be out out of soapstone and afterwards heated to "aterriperature of 800., Bearings have also been made from talc or mica slate with fibrous material added to it, such mixture being molded while in a paste-like condition.
My invention is difi'erent from these known processes because I propose to add to magnesium oxide,wood'-pulp which has previously been soaked in tar oil or in some other good lubricant. ,The wood pulp is preferabl used in the form of a fine powder but free romrosin. It is advisable to add to my above mixture :1 small amount of wood soot. To this is added some chlorrnagnesialye, and of this mixture the bear ings or bodies are formed. In order to furthei decrease the coefiicient of friction of the hearings or bodies formed-or molded of the material, the bearings after being completed are submerged in hot water in order to dissolve and extract a surplus of salts and thereby to reduce their hygroscopic qualities. In the following a full description is given how such bearings or bodies are produced.
Five to ten units of weight of wood pulp preferably containing no rosin are thoroughly mixed with ten to fifteen units of weight of tar or mineral oil. It is preferable to add to this mixture .2 to .4 units of Weight, more or less, of soot, (preferably wood soot) or at any rate suflicient to get a gray colored mixture, Thereafter add 40 to 60 units of weight of burned magnesia,
. for
Application filed April 20, 1921. Serial No. 463,042.
magensium-oxide, (MgO) and-gradually rea line dry powder of weight of Baum.
duce the latter mixture to by rubbing and stamping it. powder is added 20 to 30 units chlormagnesialye of about 35 The latter mixture is worked until it becomes a stiff paste. which latter is pressed into bearings or To this dry bearing boxes, guide blocks. loose slide valves, etc. The forming or molding slidable bodies, such as," instance, shaft bearings and thrust pulleys,
ally hardens and after that time can not be i if molded easily.
During the hardening of the composition two chemical processes are simultaneously taking place; (a) the partially breaking, lip and dissolution of the wood pulp to a celliifloid like substance and (b) the hydratization and cementation of the magnesium oxide" and its intimate composition pulp, which is undergoing or dissolution process.
After the material thus formed has become dry and hard. that .-is after about twenty-four hours, it is treated with hot water to take from it soluble salts adhering to it; The essential feature of my process is that the wood-pulp is first soaked with oil, which latter effectively prevents that the chlormagnesialye enters into the wood-pulp, which would have the effect that the wood pulp would be broken up or dissolved too much and would become a thin fluid instead of a paste of high viscosity or a plastic mass. The wood-pulp remains soaked with oil, taking from the magnesia cement. its stony character so that sliding surfacesare produced which without. oiling, work well for light loads'and moderate speeds. If a very small quantity of lubricating. oil is used from time to time with such bearings, the an higher speeds.
It is not necessary to form heavy or thick bearings or bodies of this material but a layer of say 3/ 16' is sufficient. The boxes or bodies can be made of cast iron or any suitable material. My bearing material can be bored out on machine tools if sodesired and the breaking up with the wood work exceptionally well at heavy loads a polished. Bearings or slidable bodies made according to my process have the advantage advantage for. powertransmission shafts,
- agricultural implements, signal systems,
' tion bearing composition of household machinery, and all kinds of hand operated machinery, and show particular advantages at places and under conditions where oiling at regular intervals is difficult and easily overlooked.
Extensive experiments have proved that as a result of the low co-efiicicnt of friction, it is not necessary to add to my material any metal powder to conduct heat, because very little heat is generated.
Approximate proportions of the various ingredients forming my material have been mentioned herein, but I do not restrict myself to the proportions given.
Having thus described my invention, what I claim and desire to, cover by Letters Patent of the United States is:
Claims- 1. Process of manufacturing an antifrica magnesia cement, consisting in mixing magnesiumoxyde (magnesia usta) with wood pulp previously soaked with oil, and chlormagnesialye, the resulting paste being dried to a cement of great sliding ability.
2. Process of manufacturingan antifric- 1 3. Process of manufacturing antifriction bearings of magnesia cement, characterized by the fact that magnesiumoxyde is mixed with wood pulp previously soaked with oil, and chlormagnesialye, the resulting paste being formed andthen dried to bodies of great sliding ability.
4;. Process of manufacturing antifriction bearings of a magnesia cement, characterized by the fact that inagnesiumoxyde is mixed with Wood pulp previously soaked with oil, and cblormagnesialye, the resulting paste being formed or molded to bodies, dried and then washed withfhot water.
In testimon that 1 claim the foregoing as my invention l have signed my name to this specification.
CARL SCHMIDT.
