WILLIAM: I.

No Drawing.
To all whom it may concern."
Be it known that I, WILLIAM Harris, a subject of the king of Great Britain, and a resident of the city of New York, borough of Manhattan, county and State of New York, have invented a new and Improved Metallic Packing, of which the following isa full, clear, and exact description.
This invention relates to metal packing and has for an object toprovide an improved packing which is especlally adapted to be used in connection with hot constructions and at the same time retain its packing qualities.
Another object of the invention is to provide an improved packing substantially of metal which will not disintegrate under the action of heat.
In carrying out these objects, a metal alloy is utilized which is comparatively soft but has certain qualities especially desirable for packing. This alloy may vary to a considerable extent in its ,com osition the usual ingredients and variations elng 82 to 95 per cent. lead, 2 to 1d per cent. antimony and 1 to a per cent. tin. Ihis alloy presents an anti-friction material which may be granulated and also which may be formed into a metal wool without losing its anti-frict on qualities and at the same time presentlng features which are particularly desirable in packing.
In producing a plastic metallic packing according to the present invention, the following ingredients and following proportions have been found to produce a desirable packing. 85 per cent. of the-above mentioned metal alloy in granulated form, 6 per cent. of the above mentioned alloy in the form of wool, 6 per cent. asbestos, 3 per cent. grease, 1 per cent. mica, 1 per cent. graphite and 1 per cent. moisture.
In preparing a given batch of packing a quantity of alloy of the kind above mentioned is melted until the metal is in a very liquid condition and then add crude talc and at the same time thoroughly mixing the talc and the metal, said mixing or stirring continuin during the continued addition of talc. his mixing of the talc with the melted alloy divides the alloy into small particles Specification ct Letters Patent.

or granulates the same, and the action is continued until the granular form will ass through a thirty to the inch gauze. he mlxture is then washed until all the tale has been removed from the granulated metal, said washing being by water and acts to cool the metal as well as to remove the talc.
As a second step in the preparation of the packing, a quantlty of asbestos (fiber) and metal wool above mentioned, are mixed thoroughly together in the above mentioned proportion, saturated with water, and then heated over a slow fire until the temperature increases to about 150 Fahrenheit. After this has been done mix therewith the above mentioned pro ortion of grease and flaked graphite, sai mixing being done slowly and carefully so that the parts will thoroughly commingle. 'Ihe granulated metal above mentioned and the mica in the proportion specified are then added slowly and the entire batch mixed until it is a homogeneous mass. The composition is then preferably pressed into cakes and allowed to dry slowly after which it is in condition for use.
The use of the granulated alloy presents an anti-friction metal while the mica acts to present a certain resilient action for preventing the parts from packing too tightly together. The metal wool acts to hold the asbestos and other parts together and against disintegration under the action of heat. Heretofore, in packing metal using asbestos, no means were provided for holding the asbestos and other parts in proper position and against disintegration under the action of heat so that after a comparative limited time the asbestos would disintegrate and destroy or reduce to a minimum the effective action of the packing. In the present instance, the metal wool is formed of anti-friction metal and acts to thoroughly tie the asbestos and other parts together and themica prevents too close packing. In this way the full effect of the various ingredients are secured without the objection of disintegration of any one or more parts.
What I claim is I. A metal packing comprising a metal alloy in a finely divided state, asbestos,grease,
mica and metal wool intermixed with the remaining parts for holding thesame together.
2. A metal packing comprising an anti- 5 friction .metal alloy in granulated form,
anti-friction metal alloy in wool form, asbestos, grease, mica and graphite. 3. A metal packing formed by mixing anti-friction metal alloy in granulated form 10 82 per cent., anti-friction metal inwool form 6 per cent, asbestos 6 per cent. and grease 3 per cent., mica 1 percent., graphite 1 per cent. and water 1 per cent.
4. A metal packing comprising a metal alloy in granulated form, a metal alloy in 15 wool form asbestos, a lubricating substance and means'for holding the particles of the metal alloy and the asbestos apart.
