Year: 1855

page_text: LETTERS PATENT to Richard Tidmarsh, of 23, Foxley Road, Camberwell
New Road, in the County of Surrey, Engineer, for the Invention of "AN
PROVISIONAL SPECIFICATION left by the said Richard Tidmarsh at the
Office of the Commissioners of, Patents, with his Petition, on the 4th
July 1855.
I, RICHARD TIDMARSH, of Foxley House, 23, Foxley Road, Camberwell
New Road, in the County of Surrey, Engineer, do hereby declare the nature
of the said Invention for "AN IMPROVED APPARATUS FOR LUBRICATING METALLIC
AND OTHER SURFACES WHEN IN MOTION" to be as follows:-
This Invention is designed, first, to effect a saving of oil or other lubri-
cating material used in the lubrication of moving and other surfaces; and,
secondly, to insure a continuous and uniform supply of lubricating material
to such moving or other surfaces; which objects I effect in the following
manner: A metallic or other box, cylinder, or vase is provided for con-
taining-the-lubricating material, which-box,-cylinder,-or-vase-is-fitted-with-a-
hollow stem or tube in the usual manner to convey the oil-or-other-material-
to the surface to be lubricated.

page_text: A hollow spindle is fitted to work within and across this box, cylinder, or
vase, which spindle is perforated with holes over the before-named hollow stem
or tube, with which it works nearly in contact, and a rotatory motion is given
to it by any ordinary means. This spindle is also provided with hollow arms
or spoons, which convey the oil or other lubricating material when the appa-
ratus is in motion from the cylinder or reservoir to the interior of the hollow
spindle, from which it passes through the perforations before described, and
through the tubular stem to the bearing or other surface requiring lubrication.
By means of two sets of these hollow arms.or spoons. opening in opposite direc-
tions, a continuous supply of lubricating material is secured, whether the
machinery be proceeding in its ordinary course or its motion be reversed.
When the lubricator is intended to be worked by an eccentric or comb motion,
the upper surface of the hollow stem or tube which conveys the oil from the
reservoir to the bearing or surface-to be-lubricated, and which must be level
with the bottom of the reservoir, is provided with a valve, having a vertical
spindle supported by standards, which valve is kept closed when the machinery
is at rest by a spiral spring, round the stem of the valve. At the top of the
stem a button is fixed which is raised by a cam or wiper on the driving spindle.
This button, being fixed to the stem, raises the valve, allowing the lubricating
material to pass, and the spiral spring above described returns the valve to its
seat until another revolution of the spindle repeats the operation: When the
quantity of oil or lubricating material requires to be varied from time to time,
I regulate it from a minimum to a maximum by fitting to the top of the valve
spindle of the last-described apparatus a thumb screw and index for raising
the feathered valve to any required height, at the same time omitting to use
the driving spindle-with its cam or wiper.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Tidmarsh in the Great Seal Patent Office on the
3rd January 1856.

FOR LUBRICATING METALLIC AND OTHER SURFACES WHEN IN. MOTION," upon the
condition (amongst others) that I, the said Richard.Tidmarsh, by an instru-
ment in writing under my hand and seal, 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 mouths next and immediately after the date of the
said Letters Patent. ":
NOW KNOW YE, that I, the said Richard Tidmarsh, do hereby declaré
the nature of my said Invention, and-in-what manner the same is to-be per-
formed, to be particularly described and ascertained in and by the following
statement, that is to say.
"..
This Invention is designed, first, to effect a saving of oil or other lubricating
material used in the lubrication of metallic-and other surfaces when in motion;
and, secondly, to ensure an uniform and continuous supply of lubricating
material to metallic and other surfaces when in motion; and these purposes I
accomplish by the means herein-after described, reference being had to the
Drawings hereunto annexed, and to the letters and figures marked thereon.
A metallic or other box, cylinder, or vase is provided for containing the
lubricating material, which box, cylinder; or vase is fitted with a hollow stem
or tube in the usual manner to convey the oil or other lubricating material to
the surface to be lubricated. A hollow spindle is fitted. to work within and
across this box, cylinder, or vase, which spindle is perforated with holes over
the before-named hollow stem or tube, with which it works nearly in contact,.
and a rotary motion is given to it by any ordinary means. This spindle is also
provided with hollow arms or spoons, which convey the oil or other lubricating
material when the apparatus is in motion from the cylinder or reservoir to the
interior of the hollow spindle, from which it passes through the perforations
before described, and through the tubular stem to the bearing or other surface
requiring lubrication. By means of two sets of these hollow arms or spoons
opening in opposite directions, a continuous supply of lubricating material is
secured, whether the machinery be proceeding in its ordinary course or its

page_text: Figure 1 represents a vertical section of this form of my improved lubri-
cator. A is the box, cylinder, or vase, of metal or any other suitable substance,
containing the lubricating material; B, the oil or lubricating material, which
is raised or elevated by the four tubular arms or spoons C and J, and conveyed
into the cylindrical end of the driving spindle G, and then passes through the
perforations and the tube HI to the bearing or other surface to be lubricated;
C and J are hollow arms or spoons (represented in part section only) screwed
or soldered into the hollow end of the driving spindle; G, D, the driving spindle,
working through the cylinder, vase, or oil cup, having a button or washer
attached to it to maintain it in its proper position within the vase or cup. The
driving end of this spindle, or that which is outside the cup or vase, has a flat
side, to allow the pulley or rigger E to be moved along and set at any required
distance, and this pulley or rigger is driven by a band from any convenient
source of motion; F is the perforation which allows the lubricating material to
be conveyed from the hollow arms or spoons C, J, through the vertical stem H
to the point where it is required. The hollow-spindle G is provided with a
stop or washer fixed between the hollow arms to prevent the lubricating
material raised by the forward motion spoon C passing down the back motion
spoon J.
When the lubricator is intended to be worked by an eccentric or cam
motion, the upper surface of the hollow stem or tube, which conveys the lubri-
cating material from the reservoir to the surface to be lubricated, is provided
with a valve, having a vertical spindle supported by standards, which valve is
kept closed when the machinery is at rest by a spiral spring round the stem of
the valve. At the top of this stem a button is fixed, which is. raised by a cam
or wiper on the driving spindle. This button being fixed to the stem raises
the valve, allowing-the-lubricating material to pass, and the spiral spring above
described returns the valve to its seat until another revolution of the spindle
repeats the operation.
Figure 2 represents a vertical section of this form of my improved lubricator.
A is the shaft or driving spindle; B, the button, attached to the piston or valve
spindle D; C, the cap or cover of the cup, vase, or cylinder containing the
lubricating material; D, the piston rod or valve spindle, around which is coiled
a spiral spring; E, columns or standards, supporting the piston or valve
spindle and spiral spring; G, a spiral spring, wound round the valve spindle D,
which returns the valve to its seat after having been raised by a wiper or cam
on the shaft A, to allow the lubricating material to pass to the tube J, which
conveys it to the surfaces requiring lubrication; K, a feathered valve, which
on being raised allows the lubricating material to pass into the tube J.; -L, the

page_text: valve cap, fitting close in its seat on the button I; M, a lever, worked by a
cam or otherwise from any convenient source of motion. When the quantity
of oil or other lubricating material requires to be varied from time to time, I
regulate it from a minimum to a maximum by fitting to the top of the valve
spindle of the last-described apparatus, a thumb screw and index for raising
the feathered valve to any required height, at the same time omitting to use the
driving spindle with its cam or wiper.
Figure 3 represents a vertical section of this form of my improved lubri-
cator. A, the button, through which the screw E works in order to raise the
valve C; B, the valve spindle, having one end screwed to admit of its being
raised; C, a feathered valve, which on being raised allows the lubricating
material to pass down the tube F to the moving surfaces requiring lubri-
cation; D, the index or thumb screw, by which the supply of lubricating
material is regulated; G, a guide plate attached to the valve and spindle;
H, pillars or standards on which the guide plate works; K, the cup, cylinder,
or vase containing the lubricating material.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried
into effect, I may observe, in conclusion, that I do not confine or restrict
myself to the precise details or arrangements which I have had occasion to
describe or refer to, as many variations may be made therefrom without
deviating from the principles or main features of my Invention; but what
I consider to be novel and original, and therefore claim as the Invention
secured to me by the herein-before in part recited Letters Patent, is,
First, the application of hollow arms or spoons fitted to a hollow axis, which
axis is caused to revolve by a pulley or rigger, these arms or spoons being so
arranged that a certain number of them come into operation, and supply the
lubricating material through perforations in the hollow shaft to which they are
attached when the machinery is moving in its ordinary course, and the others,
opening in an opposite direction, supply the lubricating material when the
motion of the machinery is reversed, and the supply ceases altogether when the
machinery is at rest.
Secondly, the application of a lever attached to a spindle, which is put in
motion by a stud or any similar contrivance cast on or screwed into the
eccentric or cam, the said spindle carrying a wiper which raises a button in
connection with a valve and spindle, a spiral spring being wound round the
said spindle in order to close the valve after the eccentric_or_cam_has raised
and passed the button.

page_text: one end of the said spindle being screwed and provided with a guide plate
working on standards, which spindle, guide plate, and valve are raised by
means of a button or thumb screw, having an index engraved or stamped
thereon, which indicates the rate at which the lubricating material is supplied
to the moving surfaces.
In witness whereof, I, the said Richard Tidmarsh, have hereunto set my
hand and seal, this Twenty-ninth day of December, in the year of our
Lord One thousand eight hundred and fifty-five.
