COMPLETE SPECIFICATION.
An Improved Lubricator for Automatically Applying Solid
Lubricant to Machinery.
SAMUEL GREEN 12 Cleveland Terrace Willenhall Road Wolverhampton in the
County of Stafford Engineer 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 :-
The Invention relates to that class of devices for automatically applying solid
Lubricant to Machinery without waste, and as required. The Invention is explained
by reference to the accompanying drawing. Fig. 1 the Receptical A, is of Cylindrical
form, provided at the bottom with B screw thread cut on its surface to screw to
that part of Machinery to be Lubricated. C is a Cover with screw to fasten to
receptical A, in which an Orifice is provided, to admit pressure of Atmosphere.
Fig. 2, is an Elevation, part of the Receptical A, being away, showing the Construction
of the Inner Machenism of the Lubricator, which is partly filled with the Lubricant.
D is a Conoid Leaden Piston, through which passes an Archemedean thread E, as
shown in Fig. 2. F is an Archemedean Spiral running through the thread E, of the
Conoid Leaden Piston, the bottom b, and Cover C. are recessed to receive Conoid
Leaden Piston.
The method of applying it is as follows. The Receptical A, being filled or nearly
so with the Lubricant, the Conoid Leaden Piston D, together with Archemedean
Spiral F, is replaced in Receptical A. The Spiral F, runs through Piston D, and
through Lubricant, to that part of Machinery to be Lubricated, the Piston D, in
Fig. 3, when moved up or down the Spiral F, would cause the Spiral to revolve.
Consequently, as the Spiral F, Fig. 2, conducts heat to Lubricant, the dead weight of
Conoid Leaden Piston, assisted by the pressure of Atmosphere, admitted through
Orifice of Cover C, the Piston begins to move, pressing out the Lubricant slowly,
and as required, and in its motion, causes Spiral F to revolve, thus preventing all
obstruction, and assisting in applying the Lubricant to that part of Machinery to be
Lubricated, sufficient passage is given between the interior of bottom neck B and
Spiral, so as to meet all requirements.
The Piston draws out with Spiral, the bottom end being shaped to prevent it
pulling through Piston.
Having now particularly described, and assertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare, that what I
claim is,
1st. In Lubricator a Conoid Leaden Piston, provided with an Archemedean thread.
2nd. An Archemedean Spiral, passing through Conoid Leaden Piston, to that part
of Machinary to be Lubricated.
3rd. The Conoid Leaden Piston, acting upon Archemedean Spiral, causes the
Spiral to revolve, and thus preventing all obstruction, and assisting in applying the
Lubricant to that part of Machinery to be Lubricated, giving it a regular, and nessasary
supply.
4th. The receptical A, provided with a cover and bottom recessed to receive
Conoid Leaden Piston, the Lubricator may be made.of Glass, Brass, Iron, Tin, or
any other metal to suit its purpose.
