Improvements in Packing for Journal Bearings and the like.
JOHN MILTON HAGY, of 229, South Forty-second Street, Philadelphia, Penn-
sylvania, United States of America, Manufacturer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:
-
My invention consists of a packing for a journal, axle shaft, or the like, formed
of a core or body and a jacket or cover wound thereon, producing a wad or ball
of pliable and elastic nature, the same readily absorbing oil or lubricant, with
which it is saturated, and effectual applying the same to the journal, it being also
easily placed in position in the box or bearing and uniformly seating itself, and
possesses other advantages as will be hereinafter set forth.
It also consists of means for supplying the core of the wad or ball with oil or
lubricant independent of that furnished by saturation or absorption, especially
when the supply of such oil or lubricant is low.
In the accompanying drawing:-
Figure 1 represent a side elevation of a packing embodying my invention.
Figure 2 represents a diametrical section thereof.
Figure 3 represents a front view of the packing in operative position.
Figure 4 represents a side view thereof drawn to a reduced scale.
Similar letters of reference indicate corresponding parts in the several figures.
A designates a packing composed of the core C of " waste" and the jacket B, the
latter consisting of a yarn wound on the core and secured in any suitable manner,
producing a wad preferably of the form of a ball, the same being pliable and
elastic in its nature, and one that will not disintegrate or become undone.
It will seen that the packing may be conveniently placed in position in the
box, it requiring no special skill in order to do so and readily accommodates
itself to the contour of said box and the journal, and when the latter is in operation,
the packing presses uniformly against the same, but with a light touch, thereby
avoiding severe or rapid wearing-away of the same, and hence its durability is
increased, while at the same time there is a saving in oil or lubricant. My
improved packing will not disintegrate, and thereby allow loose particles to pass
under the brasses or work-out of the box, and a predetermined amount of packing
may be used as the size of the wads or balls will regulate the same. For ordinary
purposes four wads or balls are sufficient for a journal or the like, two in front,
and two in the rear and said balls will constantly retain their size and be uniform
in their action of the journal.
In order to supply the core with oil or lubricant, especially when the same is
low or limited, there are passed through the wad or ball, the pieces D of yarn
whose ends E are outside of the same, or exposed, acting as wicks to take up the
oil or lubricant and by capillarity feed it to the core as well as to the journal
where said ends contact thus increasing the extent of lubrication due to the
different sources afforded.
In order to prevent the pieces 1) from being torn-out or removed from the body
of the wad or ball, the portions of the ends of the same near the surface of the
.

page_text: wad or ball are knotted or otherwise enlarged forming stops F whereby said pieces
are connected with the wad or ball in a manner sufficiently secure for all practical
purposes.
It will also be seen that wads or balls constructed in accordance with my inven-
tion may be conveniently handled and transported, and readily applied to their
places of service, their spherical shape being most favourable to facilitating such
handling.
There is also economy in the use of the packing owing to its elastic nature due
in the main to the expansive action of the core, assisted by similar conditions of
the jacket or encasement. Besides this, as the wads or balls are made of approxi-
mately proper sizes or dimensions, overpacking or under-packing which occasions
hot boxes and accidents is prevented.-
In the use of the terms waste and yarn, I include all material fibrous or other-
wise possessing good capillarity and elasticity or expansibility.
Having now particularly described and ascertained the nature of my said inven-
tion cand in what manner the same is to be performed, I declare that what I
claim is:
1. A packing for the purpose stated, consisting of a spherical wad composed
of a core of loose material and jacket therefor of yarn wound thereon..
2. A packing for the purpose stated, consisting of a wad of absorptive material,
and a piece or pieces of yarn in said wad with its ends exposed on the surface of
the wad.
3. A packing for the purpose stated, consisting of a wad of absorptive material;
and a piece or pieces of yarn in said wad with its or their ends exposed on the
surface of the wad, the end portion of said piece or pieces having stops thereon for
securing purposes.
4. A spherical wad or wall of absorbent material formed of a core of waste and
a jacket of yarn wound thereon, and a piece or-pieces of yarn passed through said
jacket and core and having one or both ends exposed at the surface of the wad or
ball.
5. A core and jacket of absorptive material forming a packing, substantially
as described.
