IMPROVEMENT IN JOURNAL-BOX LININGS.

ATENT Specification forming part of Letters Patent No. 138,641, dated May 6, 1873; applica on filed January 29, 1873. 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 JournaLBoxes and other rubbing surfaces, of which the following is a specifica-tion, reference being had to the accompanying drawing forming part of the Sa-Ille.

On the 12th day of April, 1870, certain Letters Patent of the United States were issued to me, numbered from 101,862 to 101,869, inclusive, for certain compositions of matter denominated metaline,7 and for the process or method of making the same, as also the of nce it performs, to which reference is made.

The invention herein intended to be described and claimed relates to a special mode of applying the said several kinds of metaline or their equivalent, or any of them,t0 practical use; and consists in a combination of metaline with the material, in the manner and for the purposes hereinafter particularly described.

Figure 1 is an edge view of a plate of copper, brass, or other suitable metal, showing the first stage of' one of the modifications of my invention. t Fig. 2 is a surface view of the same in perspective. Fig. 3 is an edge view of the same after it has been subjected to pressure, and thus completed for use. Fig. 4 is a surface View of the same in perspective. Figs. 5, 6, 7, and 8 are similar views, respectively, of another modification of my invention.

In carrying out my invention as shown in Figs. l, 2, 8, and 4, a sheet of metal has a number of right-angled channels or grooves cut into its surface, as shown, to a depth of, say, :half the thicknessV of the sheet. These' f grooves are then filled with finely-powdered metaline, for a description of which, and the method of prepa-rin g which, reference is made to the Letters Patent of April l2, 1870, here-` inbefore alluded to. The sheet with the metaline filling the grooves is then subjected to severe pressure, preferably by running the same between rollers, so as to reduce it considerably in thickness, whereby i e metaline is at once compacted into a sol; mass, and

the metal between the grooves spread laterally at the surface out upon e met-aline,

thereby making the grooves bi1 ader at the base than at the top, forming a d etail space,

as seen in Figs. 3 and 4, and us securely holding the metaline in the groo s..

' A modification of this invent n is to cast or otherwise fabricate plates wit short studs or pins standing up at short di tances from' each other over the surface, a i lling the spaces between the pins with p dered met-V aline, as seen in Figs. 5 and 6, d then subjecting the plates thus prepare to pressure,

preferably between rollers, whe by the pins will be flattened or spread out at; he top, and

the metaline at the saine tim compressed and consolidated, as seen in Fig 7 and 8.

It is evident that the form d construction of the plate may be vario ly modified` without departing from the spi tof my invention. For example, grooves; or channels may be out crossing each other t right anf gies, or any angle, so as to fori projections' square, diamond-shaped, or an lother shape desired.`

Pins or wires may be inser d either as studs or staples or loops, the .by forming spaces into which the metaline m t be pressed and held, or recesses may be ma e in the surfaces by drilling or punching pr tly through themetal; the object aimed at b1 ing to make inthe surface of a continuous s et of metal depressions or channels, into w ch metaline may be deposited, compacted g y pressure, and securely held, so as not to; e displaced by use.

In order that the thing desc bedmay be distinctly seen, I have made th `drawing on a somewhat enlarged scale, it i t being advisable, usually, to use metal p tes as thick as represented in the drawing.

For journal-boxes it is desira l e that these plates, when" completed, should e sufficiently thin to be conveniently bent i to a form to conform to the journal for which, hey may 'be intended. l

Such purpose, as has been indicated, is to line journal-boxes and provide other surfaces subjected to friction in use, With a material which will obviate the necessity of employ ing oil or other extraneous lubricator, an office performed by metaline, as fully explained in my patents of the 12th of April, 1870, above referred to.

What I claim as a new manufacture is- A sheet of metal, With which is incorporatr ed metaline, substantially'as and for the purposes specified.

' STUART GWYNN.
