Year: 1874

page_text: LETTERS PATENT to William Robert Lake, of the Firm of Haseltine,
Lake, & Co., Patent Agents, Southampton Buildings, London, for
the Invention of "IMPROVEMENTS IN LUBRICATING APPARATUS FOR THE
SPINDLE STEPS AND BOLSTERS OF SPINNING FRAMES AND FOR OTHER BEARINGS."
-A communication from abroad by Charles Albert Shaw, of
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition,
on the 28th November 1874.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN LUBRICATING APPARATUS
FOR THE SPINDLE STEPS AND BOLSTERS OF SPINNING FRAMES AND FOR OTHER
BEARINGS," a communication, to be as follows:-
This Invention relates to means for lubricating the spindles of spinning
frames and the like, and consists primarily in the use of a ring in the

page_text: oil cup of the step or bolster so arranged and operating as to deliver
the proper quantity of oil to lubricate the spindle, and to prevent the
passing of the sediment and impurities in the oil through the oil aper-
tures. It also consists in a novel construction and arrangement of
the parts by which a greater saving of oil is effected, and better results
produced than with the steps and bolsters in ordinary use. Leading
from the said cup there is an oil hole or aperture through which the
lubricating fluid passes to the spindle near its beveled end, or immediately
at the point of support. Near its upper end the socket is enlarged to form
an auxiliary cup, the object of which is to catch the surplus oil carried
up by the spindle and prevent its being thrown from the socket by
centrifugal force, the oil so caught being returned to the first cup through
a conduit. Within the said cup encircling a socket piece and covering
the mouth of the said aperture there is a loosely fitting thin metallic
ring which acts on the principle of capillary attraction to hold back
or prevent the too rapid flow of oil to the spindle in a manner which
will be readily apparent to all conversant with such matters. The ring
also prevents the passage of dirt and the sediment of the oil through
the aperture. When the said aperture is located above the bevel on the
lower end of the spindle, the oil is liable to be thrown upward without
coming into contact with the point of support or principal bearing
surface.
•
In applying this Invention to a bolster I arrange within the oil cup
and encircling the bushing a loosely fitting thin metallic ring, the
apertures in the bolster, unlike the above-named aperture in the step, are
preferably located near the top of the ring for the following reason :—
In the step means are provided for returning the surplus oil to the cup,
which may be filled, if desired, above the ring, but in the bolster there
are no such means; the ring is therefore made wider or higher, and the
aperture formed or located near its top, the cup not being filled with
oil to the height of the ring the oil is taken up to the aperture by
capillary attraction.
It will be obvious that an oil cup provided with apertures and having
a ring disposed therein, as described, may be used to advantage in a
variety of journal boxes and hearings when it is desirable to control the
delivery and economize the use of the lubricating oil.

filed by the said William Robert Lake in the Great Seal Patent
Office on the 26th May 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of November, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for "Herself, Her heirs and suc-
cessors, give and grant unto me, the said William Robert Lake, Her
special licence that I, the said William Robert Lake, my executors,
administrators, and assigns, or such others as I, the said William
Robert Lake, my executors, administrators, and assigns, should át any
time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN LUBRICATING APPARATUS FOR SPINDLE STEPS AND
BOLSTERS OF SPINNING FRAMES, AND FOR OTHER BEARINGS," a communication
to me from abroad by Charles Albert Shaw, of Boston, Massachusetts,
United States of America, upon the condition (amongst others) that I,
the said William Robert Lake, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to, be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the accom-
panying Drawing forming a part of this Specification:
This Invention relates to means for lubricating the spindles of spinning
frames and the like, and consists primarily in the use of a ring in the
oil cup of the step or bolster so arranged and operating as to deliver

page_text: the proper quantity of oil to lubricate the spindle and to prevent the
passing of the sediment and impurities in the oil through the oil
apertures. It also consists in a novel construction and arrangement of
the parts, as herein-after more fully set forth, by which a greater saving
of oil is effected, and better results produced than with the steps and 5
holsters in ordinary use
Figure 1 is a vertical longitudinal section showing my improvements
applied to a spindle step, and Figure 2 is a vertical longitudinal section
showing the same applied to a spindle bolster.
In Figure 1 A is the body of a step; B, the bushing or socket
picce; C, the socket; D, the cover or cap; and E, the oil cup. Leading
from the said cup there is an oil hole or aperture H through which the
lubricating fluid passes to the spindle near its beveled end, or imme-
diately at the point of support. Near its upper end the socket C is
enlarged to form an auxiliary cup a, the object of which is to catch the
surplus oil carried up by the spindle, and prevent its being thrown from
the socket by centrifugal force, the oil so caught being returned to
the cup E through the conduit G. Within the cup E encircling the
socket piece B, and covering the mouth of the aperture H, there is a
loosely fitting thin metallic ring F, which acts on the principle of
capillary attraction to hold back or prevent the too rapid flow of oil to
the spindle in a manner which will be readily apparent to all conversant
with such matters. The ring also prevents the passage of dirt and the
sediment of the oil through the aperture. When the aperture H is
located above the bevil on the lower end of the spindle, the oil is liable
to be thrown upward without coming into contact with the point of
support or principal bearing surface, and I therefore arrange it as
shown.
In Figure 2 B is the body of a bolster; A, the box or bushing
through which the spindle passes; C, the cap; E, the oil cup, and a, a,
oil holes or apertures leading from the oil cup to the spindle opening
or box. Within the oil cup and encircling the bushing A there is a
losely fitting thin metallic ring D, similar to the ring F in Figure 1,
but wider, and the apertures a, a, in the bolster unlike the aperture H in
the step, are preferably located near the top of the ring for the
following reason, that is to say :-In the step means are provided for

page_text: returning the surplus oil to the cup which may be filled, if desired, above
the ring, but in the bolster there are no such means, the ring is there-
fore made wider or higher, and the aperture formed or located near its
top, the cup not being filled with oil to the height of the ring; the oil is
taken up to the aperture by capillary attraction.
It will be obvious that an oil cup provided with apertures, and having
a ring disposed therein, as described, may be used to advantage in a
variety of journal boxes and bearings, where it is desirable to control the
delivery, and economize the use of the lubricating oil.
Having thus fully described the said Invention, as communicated to
me by my foreign correspondent, and the manner of performing the
the same, I wish it understood that I do not confine myself to the
lubricator described in connection with spindle steps and bolsters, and
that I claim,
First. A lubricating device, consisting of an oil cup provided with a
hole or aperture leading to the bearing or surface to be lubricated, and
with a ring disposed within the cup, as above described.
Second. In a spindle step the oil cup E, ring F, and apertures G, H,
combined to operate, as above set forth and for the purpose specified.
Third. In a spindle bolster the apertures, a, a, constructed and arranged
to lead from the oil cup E, near the top of the ring D, as above set forth
and for the purpose specified.
Fourth. In a spindle step having the oil cup E, ring F, and apertures
G, H, the auxiliary cup a, for catching and returning the oil to the cup,
as above set forth.
In witness whereof, I, the said William Robert Lake, have here-
unto set my hand and seal, this Twenty-sixth day of May, in
the year of our Lord One thousand eight hundred and seventy-
Witness,
