page_text: LETTERS PATENT to Robert Gray Morton, of Errol Works, in the County
of Perth, North Britain, Engineer, for the Invention of "A NEW OR IM-
PROVED APPARATUS OR MEANS FOR SUPPLYING OIL FOR LUBRICATING
PURPOSES."
Sealed the 13th May 1879, and dated the 25th November 1878.
PROVISIONAL SPECIFICATION left by the said Robert Gray Morton at
the Office of the Commissioners of Patents on the 25th November 1878.
ROBERT GRAY MORTON, of Errol Works, in the County of Perth, North
Britain, Engineer. A NEW OR IMPROVED APPARATUS OR MEANS FOR SUPPLYING
OIL FOR LUBRICATING PURPOSES."
This Invention has reference to or for its object the better lubricating than
heretofore of the shaking or high speed journals or cranks and their working or
bearing bushes or boxes of threshing and other grain dressing or agricultural and
other machines where great shaking motion and high speed are necessary, and as a
consequence liability to dust and defective lubrication are unavoidable.
And the nature and novelty of the Invention consist in casting or forming the
oil or lubricating box on the cover or upper part of the bearing or pillow block, or
forming it separately, so that it can be screwed or otherwise secured liquid tight
thereon, and of a deep vessel shape, round or oblong, transversely across the cover
or in a line over the bearing, with a liquid tight lid or top screwed down on it
with a layer of leather or other equivalent soft jointing material between it and
the upper edge of the oil box to prevent all escape of the oil by the shaking, or the
entrance of dust to the oil or journal. The oil vessel being made deep as stated

page_text: and fitted with one, two, or more needle lubricators or metal pins working or
shaking loosely down through holes formed in the bottom from the inside of the
box, over and along the bearing and journal or crank to be lubricated, with the
lower ends of the pins resting on this, so that the motion of the needles on
the journals assists the descent of the oil in a small regular quantity, as is well
known by the action of the ordinary portable needle lubricators with glass bottles,
but which from their liability to be jerked out are quite unsuitable for the shaking
or high speed mechanism for which this new or improved lubricating box is
specially designed or invented, and for which protection is hereby desired to be
secured.

by the said Robert Gray Morton in the Great Seal Patent Office on the
15th May 1879.
ROBERT GRAY MORTON, of Errol Works, in the County of Perth, North Britain,
Engineer. "A NEW OR IMPROVED APPARATUS OR MEANS FOR SUPPLYING OIL
FOR LUBRICATING PURPOSES."
My said Invention has reference to or for its object the better lubricating than
heretofore of the shaking or high speed journals or cranks and their working or
bearing bushes or boxes of threshing and other grain dressing or agricultural and
other machines where great shaking motion and high speed are necessary, and as a
consequence liability to dust and defective lubrication are unavoidable.
And in order that the nature, novelty, and mode of performing any said Invention
may be properly understood, I will now proceed to describe the Figures on the
Sheet of Drawings which I have hereunto appended for the purpose of showing the
best modes and means I am at present aware of for putting my said Invention into
effect or practice, the same reference letters indicating the same or equivalent parts
in the different Figures where seen.
Figures 1 and 2 are a side elevation and a transverse section of the crank
shaft X of the straw shaking and delivery frames x of a threshing machine for
dressing and cleaning corn and other grains, showing one of my crank journal
bearing blocks or bushes A' and lubricating box A in section, the latter A screwed
in two halves to the former A' at A", which is cast in one with the bearing block B
and arms B', which secure it by.screws at B11 to the under side of the rocking wood
frame x, all constructed in accordance with and illustrative of one modification or
combination of the parts of my new or improved lubricator or box for supplying oil
or other lubricant to the shaking bearings of threshing machines and other
machinery.
Figures 3 and 4 are a side elevation and edge section of the crank pin end y of
an upright connecting rod of a crank overhead steam engine or other such crank
shaft, of which Y is the crank and Y¹ the journal of the crank pin on which the
bearing bushes A¹ work, and are secured by the two screw bolts y to the end of
the connecting rod y in a usual manuer, but in this case having the lubricating
oil box A cast in one with the upper end bush A', and showing a slightly different
modification or combination of the parts of my Invention or new and improved
lubricator from that shown in Figures 1 and 2.
Referring to Figures 1 to 4 my Invention consists in casting or forming the oil
or lubricating box A on the cover or upper part of the bearing bush A² or pillar
block B, as seen in Figures 3, 4, and 1, 2, respectively, or otherwise it might be
formed separately and screwed or otherwise secured fluid tight to these A¹ or B of
a deep vessel shape round or preferably oblong transversely across the cover, or in
a line with and over the journal bearing X or Y', as seen in Figures 1 and 4, and
fitted with a fluid tight lid or top a screwed down on it, with a layer of leather or
other equivalent soft fabric a¹ jointing material between it and the upper edge of
the oil box A to prevent all escape of the oil by the shaking, or the entrance of air
and dust to or with the oil to the working or journal bearing surfaces X, Y¹. The
oil vessel A made deep enough, as stated, is fitted with one, two, or more
"needle
lubricators" or metal pins b, working or shaking loosely in nearly vertical holes 6¹
formed down through the bottom of the inside of the box A and bearing block B
or A, over and along the bearing and journal or crank X, Y, to be lubricated.
The lower ends of the lubricating pins 6 resting on the journal X, Y', so that the
motion of these and the needle bon the journals assist the descent of the oil in a
small regular quantity, as is well known by the action of the ordinary portable
needle lubricators used with glass bottles, but which from their liability to be
jerked out are quite unsuitable for the shaking or high speed mechanism for which

page_text: this new or improved construction of lubricating box is specially designed or invented.
The oil or other lubricant employed is applied or filled into the vessel A from time
to time as it becomes empty or exhausted, by screwing off the cover a and filling it
and then screwing down the cover again which prevents the escape of all oil
by the shaking, and the screw bolts A¹¹ maintain so close a joint as to be liquid
tight between the oil vessel A and the bearing block B, B', cast in one and the
upper journal or bearing bush A¹ formed separate and of hard wood as shown in
Figures 1 and 2, but this might be formed of brass or other bush bearing metal
when preferred, and further when desired or more convenient may be formed in
one with the oil vessel A as shown in Figures 3 and 4. The parts of the bearings
might be further modified in many other respects as to size or form and mode of
securing them liquid tight (when the oil box A is formed separate from the upper
bearing bush A¹) from that shown in the two examples given on the Drawings.
Although my said improvements have only been described as applied to shaking or
high speed journals or cranks and working or bearing bushes or boxes of machines
used for thrashing and dressing grain and similar purposes, it is to be understood
that the Invention is equally applicable to stationary or fixed pillow blocks,
bearings, or pedestals, of which it has not been thought necessary to give examples
on the Sheet of Drawings.
Having now described the [nature and mode of performing my said Invention,
I desire to state in conclusion that I lay no claim to the mere use of feeding
lubricating needles as b, which I am aware have heretofore been employed fitted
within glass bottles and working down through their inverted necks and stoppers
inserted portably into the ordinary upper bearings of machines for the lubrication of
these, but what I consider novel and original, and therefore claim as the Invention
secured to me by the herein-before in part recited Letters Patent is,-
The combination and use of a fluid tight oil box A, a, with one or more metal
feeding needles or wires b permanently formed in one with or secured on to the
upper cover or bearing block (as B, B', Figures 1 and 2), or upon the upper bearing
bush or cover (as A', Figures 3 and 4) for the purpose of lubricating the shaking
or other bearing bushes of thrashing machines and other grain dressing and
agricultural machines, or of the crank pin ends of connecting rods or other such like
journal bearings of machinery, all substantially as herein described in reference to
the accompanying Drawings or any mere modification or analogous application
thereof.
In witness whereof, I, the said Robert Gray Morton, have hereunto set my
hand and seal, this Thirteenth day of May, in the year of our Lord. One
thousand eight hundred and seventy nine.
