IMPROVEMENT IN JOURNAL-BOX LININGS.

Specification forming part of Letters Patent No. 138,643, dated May 6, 1873; app cation filed January 29, 1872. 1

To all whom it may concern:

Be it known that I, STUART GWYNN, of the city, county, and State of New York, have invented a new manufacture, the same being an Improved Lining for J ournal-Boxes and other Rubbing-Surfaces, of which the following is a specification, reference being had to the accompanyingdrawingforming part of the same.

On the 12th day of April, 1870, certain Letters Patent of the United States were issued to me,numberedfrom 101,862 to 101,869,inelusive, for certain compositions of matter denominated metaline, and for the process or method of making the same, as also the ofiice it performs, to which reference is made. The invention herein intended to be described and cl aimed relates to a special mode of appl yin g the said several kinds of metaline or any of them, or their equivalent, to practical use; and consists in a combination of metaline with the material, in the manner and for the purpose particularly described.

Figure 1 is a perspective view, showing the first step in the process of making my improvement. Fig. 2 is a similar view, show ing the completed article. Fig. 3 is a similar view of a modification of my invention, the same being a tube formed of sheet metal filled with powdered metaline. Fig. 4 is a similar view of the same tube after the same has been subjected to pressure, and somewhat flattened. Fig. 5 is a similar view of the same cut into halves. Fig. 6 is a similar view of one of said halves after the same has been subjected to still greater pressure, so as to sufiiciently consolidate the metaline for use.

In fabricating this article, shown in Figs. 1 and 2, I take a strip of she metal, preferably copper or brass, andbe d it, along its whole length, into the form re esented, which is the half of a somewhat-flat ned tube. This I fill with any one of the varie ies of metaline, or their equivalent, describe 'n my said patents of April 12, 1870, that I ay elect to use, having reference to the deg'r of friction to which it is to be subjected in use. Then, by the use of suitable rolls or mo is, so constructed as to prevent the escape o the metaline, I subject it to severe pressure 1 on the sides of the half tube, thereby compre ing and consolidating the metaline, as repr ented in Fig. 2.

It is well, in the act of pr sure or other: wise, to turn the upper edge of the sheet in upon the metaline, thereby l king it. in or 1 use a tube made of sheet tal, filling this with metaline, and flatteni it down by pressure into the form show and 6. 1

It is designed to place a n mber of pieces of the article side by side little distance apart within the journal-box, ith the open or metaline edges forming a per} ion of the bearing-surfaces for the journa which may be done by cutting recesses into he interior face of the box, or in any other s1: table manner.

What I claim as a new art: le of manufacture is- A sheet of metal, with whi ed metaline, substantially as, pose specified. 1
