Description

C. C. HALL PACKING Filed Jan. ll 1924 Patented Sept. 23, 1924.
PATENT oFFIC'E.
CHAR-LES C. HALL, F KALAMAZOO, MICHIGAN.
PACKING.
Application filed January 11, 1924.
To all whom t may concern.'
Be it known that I, CHAnLns C. HALL, a citizen of the United States, residing at the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Pat-kings, ot' which the following is a specification.
This invention relates to improvements in packings.
The main object of this invention is to provide an improved packing which is well4 adapted for general use on steam or hydraulic packings and for high temperatures and heavy pressures.
A further object is to provide an improved packing which is strong and durable and at the same time has good anti-friction and lubricating qualities.
Further objects, and objects relating t0 structural details, will definitely appear from the detailed description to follow.
I accomplish the objects of my invention by the devices and means described in the following specification. rlhe invention is clearly defined and pointed out in the claims.
A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this application, in Which:
Fig. I is a fragmentary-plan view of a thin sheet of metal or metal foil such as I employ in my improved packing.
Fig. II is a plan view of the sheet crumpled and coated with lubricant.
Fig. III is a detail View illustrating one of the steps of manufacture, the thickness of the metal being being very greatly exaggerated for convenience in illustration.
Fig. IV is a cross section through my improved packing in cylindrical cross section,
the lead and the aluminum being indicated by the difference in cross seetionino.
Fig. V is a detail perspective view of my improved packing reduced to rectangular cross section.
In the drawing similar reference characters refer to similar parts throughout the several views.
Referring to the drawings, l represents a thin sheet of metal or metal foil such as I employ in my improved packing and 2 is a Serial No. 685,566.
sheet crumpled and coated with lubricant, preferably a paste or powdered flake graphite and high temperature oil, although beeswax, japan Wax, glycerine or other lubricant may be employed.
I employ one or more sheets of the aluminum foil indicated at 3 and one or more sheets of lead foil indicated at 4. These thin sheets of aluminum and lead foil are both coated with the lubricant and crumpled and then Wound together preferably with the aluminum at the outside.
The lubricant is retained between the sheets and in the pockets-thereof so that it is in quite uniformly distributed condition and in suli'icient quantities to form a selflubricating packing, the lead itself being regarded by some authorities as an effective lubricant.
The aluminum foil is preferably l/lOOO of an inch in thickness and is preferably annealed. The lead foil is also thin but may be considerably thicker than the aluminum foil With satisfactory results.
My improved packing may be left in the cylindrical form as indicated in F ig. IV or it may be compacted into a rectangular form as shown in Fig. V.
My improved packing is desi 1able for many uses, it being highly desirable for instance in saturated steam up to 160 pounds pressure or for hydraulic packings, particularly high pressures, and in various relations Where lead has been deemed a desirable packing. It does not, however, have the objection that is found in lead packings of solidifying under high temperatures and pressures, the aluminum being incorporated throughout with the lead enabling the packing to be used under such temperatures and pressures as would render a packing of lead impracticable. Further, it has greater strength.
My improved packing is also highly desirable for parts moving at high speed, for instance, centrifugal pumps and the like.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
l. A packing comprising a sheet of aluminum and a sheet of lead crumpled, coated With lubricant, superimposed and rolled to- 3. A packing comprising a sheet of alumigether so that the aluminum is at the outnum and a sheet of lead crumpled, coated :side7 and compacted. with lubricant and rolled together. l0
2. A packing comprising a sheet of alulni- In witness whereof, I have hereunto sei num and a sheet of lead, coated with lubrimy hand.
cant, superimposed and rolled together so that the aluminum is at the outside. CHAQRLJS C. HALL. [1, s.|
