Improvements in or relating to the Lubrication of Spindles
or the like.
I, ROBERT WOOD, Secretary to the Firm of Emmott & Co. Limited of New
Bridge Street, Manchester, in the County of Lancaster, Newspaper Proprietors,
Printers and Publishers 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 :-
This invention relates to improvements in the lubrication of spindles or other
rotating bodies of a like nature, the object being to provide simple means of
lubrication and also devices for covering the oil receptacles and for cleaning out the
oil holes through which in some cases the lubricant is passed to the bearing.
The invention will be fully described with reference to the annexed drawings in
which
Figs. 1, 2 and 3 represent the application of my improvements to the bolster
bearings of spindles of spinning machinery.
Figs. 4 and 5 are separate views of the oil receptacle covers used in Figs. 1 and 2
and in Fig. 3, respectively.
Fig. 6 is a sectional view showing the application of my improved means for
cleaning-out the oil holes in bearings whilst
Fig. 7 is a separate view of the cleaning-out device.
In carrying out my invention I cover the oil receptacle A¹ formed in the of
top
the bearing by means of a cover A stamped from sheet metal of the desired
material to the forms shown in Figs. 4 or 5, preferably to that form indicated in
Fig. 4.
The cover A is convex at the top and is made with two flanges a and a',
the outer one a fitting easily the outside of the bolster bearing B whilst the inner
one a¹ fits in an annular groove 6 formed in the boss b. By this means the oil
receptacle is covered and all entrance of dust, fly or grit to the oil prevented. In
Figs. 3 and 5 the flange a¹ is longer and fits into a groove formed at the bottom of
the oil chamber as shown in Fig. 3. Both forms of covers shown in Figs. 4 and 5
are very light and can readily be lifted away from their normal position to allow
the receptacles A' to be filled with oil. In addition to this they can be readily
cleaned of fly or dirt.
Figs. 1, 2 and 3 show three methods of lubrication I have adopted. In Fig. I
I drill or bore a small hole c in the bolster bearing at an angle to the spindle and
in it I place a short piece of wire c' or similar material. This wire is a loose fit in
the hole and its lower end abuts against the spindle. The oil escapes from the
receptacle A' down between the surface of the wire and the hole to the bearing.
In Fig. 21 merely slit the boss b at one or more places d to allow the oil to flow
therethrough to the bearing whilst in Fig. 3 the oil receptacle cover is cut out at
one or more places e for the same purpose. This is indicated clearly in Fig. 5.
Figs. 6 and 7 show the device I have designed for cleaning dirt or the like from
the oil holes used in bearings. Fig. 6 shows the application of the device and
Fig. 7 a separate view in section. The device consists of a small metal tube a
provided with a flaring or trumpet-shaped end b. The part a fits in the oil hole
as shown in Fig. 6 and the part 6 fits the countersunk portion of the hole. The
latter projects beyond the bearing a sufficient distance to allow of its being easily
withdrawn by the hand. To ensure the dirt coming out with the tube when the
latter is being withdrawn from the hole I make it with a slight internal flange c'.
The tube may if desired be provided with a lid to prevent access of dirt to the oil

page_text: hole. In use and before applying fresh oil to the bearing the tube is withdrawn,
cleared of dirt, and replaced, after which the oil may be applied in the usual way.
By using a device of this kind it is not necessary to use any sharp instrument to
clear the oil holes and therefore there is no danger of injury to the shaft. The
tube may be made of any convenient size and be applied to either horizontal,
vertical or inclined bearings.
In conclusion I would have it understood that the methods of lubrication and
means for covering oil receptacles I have described may be applied to all classes of
vertical bearings for rotating shafts.
Having now. particularly described and ascertained the nature of my said
invention, as communicated to me by my foreign correspondent, and in what
manner the same is to be performed I declare that what I claim is —
The improvements in or relating to the lubrication of bearings for spindles or
the like, covers for the oil receptacles and dirt removing device all constructed and
arranged substantially as described and as shown in the accompanying drawings.
