PACKlNG FOB STEAM-JOINTS.

SPECIFICATION forming part of Letters Patent No. 311,707, dated February 3, 1885.

Application filed April 29, 1584. (No model.)

To aZZ whom it may concern:

Be it known that we, ALBERT A. ADAMS and WILLIAM LEE, citizens of the United States, residing at McBrides, in the county of Montcalm and State'of lvlichigan, have invented certain new and useful Improvements in Packing for Steam-Joints; and we do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to whichitappertains to make and use the same.

The object of this improvement is to produce a durable and efiicient packing for the joints of steam-chests, steam or other pipes or joints, and that can be used as a substitute for common rubber, lead, or copper gaskets, with better results. This isattainable by the means illustrated in the drawing herewith filed as part hereof.

The drawing represents a sectional view of our improved packing, showing its mode of construction.

A represents a series of transverse parallel wires laid between courses of sheet-rubber B and G. For ordinary joints the wires A need not be more than one thirtysecond of an inch in diameter, and the courses of rubber need not be more than ouesixteenth of an inch in thickness. The material can be cut with an ordinary knife, chisel, or shears to suit the construction of any joint. For ordinary purposes it will only be necessary to arrange the packing by simply superposing the rubber sheets and wires in their relative positions; but for commercial purposes and transportation the courses and layers may be held together by rivets or other suitable devices located at various intermediate points. The

variations in the courses of the wire will enable the joint to be made tight without the pressure otherwise necessary, which would cause the packing to adhere to the surfaces of the parts joined, and thus be mutilated and disabled for further service when from various causes it is necessary to open the joints. Good rubber-hose pipe may also be formed from this combination of transverse parallel wires and sheet-rubber by lapping and riveting the courses thereof.

\Ve are aware that previous to our invention it has been proposed to make belting by covering wire fabric with rubb'encoated duckcloth, so that the article could be readily pressed and vulcanized to form a composite belting. ()ur invention, however, may be readily distinguished from such construction and article, in that there is no intimate adhesion of the wire with the sheets of rubber covering the same, the interposed wires maintain ing' the said sheets from contact with' each other, and thereby enabling said sheets to have a slight yielding capacity to adapt them for packing purposes. It will therefore be obvious that there will be no necessity for exerting a great degree of pressure on the packing to secure tight joints, and thereby ultimately causing the rubber surfaces to adhere to the parts to be packed.

Having explained the construction and operation of our improvement, what we claim as new, and desire to secure by Letters Patcut, is-

As an improved article of manufacture, a packing consisting of sheets of rubber having alternating wires interposed loosely between them, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
