Improvements in or connected with Apparatus or Appliances for
Lubricating Journals and Bearings!...
:
I, LEWIS CHARLES WALLAOH of 57 Gracechurch Street, in the City and
County of London,. Merchant, do hereby declare the nature of this invention to bo
as follows:-
My invention refers to improvements in or connected with apparatus or
appliances for lubricating the bearings, journals, or necks, or the like; and parts of
machinery exposed to friction especially such as are located in open; or partially
open bearings &c., as for example, roll necks, calender bearings, tunnel shaft
bearings and the like, for example, piston rude. The aforesaid parts have been
hitherto lubricated by applying lubricant in direct contact with the shaft, or by
enclosing same in a bag of canvas or other porous material; or in other cases by
enclosing the lubricant in an envelope or case of wire gauze or sheet metal; in such
construction the heat generated by the rotation of the part to be lubricated, too
quickly melts or dries up the lubricant.
Now according to my invention I provide a metallic or other receptacle or
container composed of perforated sheet metal, wire gauze, or of wire, twisted,
built up, or woven' and formed of a shape adapted to fit the part of the machinery
to be lubricated and to come into contact therewith; I'line the container with
asbestos cloth or a lining of pure asbestos or with asbestos combined' with other
non-conducting inaterials. Within such lining 1 place the lubricating material
which should. preferably be of a solid nature and in the form of bricks, but may
also be of a semi-solid, or even-liquid nature.
The non-conducting lining of asbestos, or the like, should be of such thickness
or substance as to prevent heat from the bearing too quickly melting or injuring
the lubricant, but (especially in the case of solid or semi-solid lubricants)
admitting such heat as will be desirable for producing just such sufficient liquification
of the lubricant to cause same to permeate the lining so as to come in' contact" with
the metal surface to be libricated.
Sometimes the holders may be made or manufactured' of asbestos and' wire
-interwoven to form a metallic and asbestos case; where necessary for application
springs may be applied for holding, the lubricator in position. The case or its
asbestos liuing may be perforated.

I, LEWIS CHARLES WALLACH, of 57 Gracechurch Street, in the City of
London, Merchant, do hereby declare the nature of this invention, and in what
manner the same is to be performed to be particularly described, and ascertained,
in and by the following statement :-
My invention refers to improvements in, or connected with, apparatus or
appliances for lubricating the bearings, journals, or necks, or the like parts of
machinery exposed to friction especially such as are located in open or partially
open bearings &c., as for example, roll necks, calendur hearings, tunnel shaft
bearings, and the like, for example piston rods. The aforesaid parts have been
hitherto lubricated by applying lubricant in direct contact with the shaft, or by
enclosing same in a bag of canvas or other porous material, or in other cases, by
enclosing the lubricant in an envelope, or case of wire gauze, or sheet metal; in
such construction the heat generated by the rotation of the part to be lubricated,
or atmospheric heat too quickly melts or dries up the lubricant.
Now according to my invention I provide a metallic, or other receptacle, or
container, composed of perforated sheet metal, wire gauze, or of wire, twisted,
built up, or woven, and formed of a shape adapted to fit the part of the machinery
to be lubricated, and to come into contact therewith: I line the container with
asbestos cloth, or a lining of asbestos fibre, or with asbestos combined with some
other non-conducting materials such as cotton or silk. Within such lining I place
the lubricating material, which should preferably be of a solid nature and in the
form of bricks, but may in some cases be of a semi-solid, or oven liquid nature.
The non-conducting lining of asbestos, or the like, should be of such a thickness,
or substance, as to prevent heat from the bearing or the atmosphere too quickly
melting or injuring the lubricant, but (especially in the case of solid, or semi-solid
lubricants) admitting such heat as will be desirable for producing just sufficient
liquification of the lubricant, to cause same to permeate the liuiug (so as to come
into contact with the metal surface to be lubricated).
Sometimes the bolders instead of having an outer wire case, and an inner living
of asbestos, may be composed or manufactured wholly of asbestos and wire
interwoven, or the wire may be a framework to form a combined metallic and
asbestos case, the wire giving the structure of the case the requisite stiffness, while
the asbestos prevents the too rapid molting, or drying up, of tho lubricant. The
case or its asbestos lining may be perforated.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I doolare that what I
claim is :-
1. In or connected with the lubrication of journals and bearings, the employinent
of containers, or lubricant recipients, or holders, composed of perforated sheet
metal, wire gauze, wire, twisted or otherwise built up or woven; in combination
with an interior or exterior lining of asbestos (for such holders), made in the form
of cloth, or of asbestos combined with some other non-conducting material, such as
cotton or silk, such combined lubricant-recipients, or holders, being utilized for
bolding and supplying lubricant to the journals or bearings to be lubricated, all
substantially as, and for the purposes, herein before described.
2. In or connected with tlie lubrication of journals and bearings, the employment
of a container for lubricant composed of asbestos, interwoven or interlaced with

page_text: wire, or having a frame of wire or the like, to give the structure sufficient rigidity,
while the asbestos prevents the too rapid transmission of heat to the lubricant,
substantially as, and for the purposes, hereinbefore described.
