We, JOHN ROBERT YATES, of New Mills, in the County of Derby, Engineer, and
FREDERICK ROBERT PUTZ, of 8 and 9, South Parade, Manchester, in the County of
Lancaster, Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention relates in part to means or devices for controlling the outlets
of lubricators, such controlling devices being capable of being locked in any
desired position so as to ensure the constant flow or passage of the lubricant at
any desired rate.
The outlet pipe or equivalent part of the lubricator is furnished with a trans-
verse plug capable of angular movement, and provided with a passage or opening
in a manner similar to an ordinary tap plug. By turning the plug, therefore,
the lubricant may be allowed to flow freely or it may be cut off altogether. The
plug is furnished or is combined with a suitable locking device by means of which
it may be held rigidly in any desired position, and may be either parallel, taper
or screwed.
In one form of locking device the end of the plug does not extend right through
the lubricator outlet, which has a set screw or the like mounted therein and capable
of being turned so that its end engages with the plug, which, in this case is pre-
ferably screwed. The set screw is advantageously mounted in a line which is
approximately a continuation of the plug, or is parallel with its produced axis.
In another form the head of the plug may carry a quadrant or other plate
through which a set screw passes to engage with one of a series of holes formed
in a fixed part of the lubricator shell, or the quadrant may be provided with
several holes through any one of which a screw or pin may pass to engage with
a suitable recess in the lubricator.
In a further modification the plug may be screwed and may carry at either or
both ends a nut by means of which the plug may be locked in any desired angular
position.
A still further modification of the controlling device may be provided by
boring the plug axially from one end to the passage for the lubricant. The hole
thus formed may contain a sliding pin or ram the end of which may be moved
into the lubricant passage, thus reducing its area, or be withdrawn therefrom
altogether, the pin being locked in place by means of a nut, or transverse cotters,
or equivalent devices.
This sliding pin may be used either in substitution for or in addition to the
controlling devices before described.
Another part of this invention relates to means for securing in place the different
parts by means of which a spring operated piston expels the lubricant. The upper

page_text: screwed sleeve through which the piston rod passes and which contains the
operating spring, is provided with a nut by means of which it may be locked
in the lubricator.

We, JOIN ROBERT YATES, of Church Road, New Mills, in the County of Derby,
Engineer, and FREDERICK ROBERT PUTZ, of 8 and 9, South Parade, Manchester,
in the County of Lancaster, Merchant, do hereby declare the nature of this inven-
tion, 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 in part to means or devices for controlling the outlets
of lubricators, such controlling devices being capable of being locked in any
desired position so as to ensure the constant flow or passage of the lubricant at
any desired rate.
The outlet pipe or equivalent part of the lubricator is furnished with a trans-
verse plug capable of angular movement, and provided with a passage or opening
in a manner similar to an ordinary tap plug. By turning the plug therefore,
the lubricant may be allowed to flow freely or it may be cut off altogether. The
plug is furnished or is combined with a suitable locking device by means of which
it may be held rigidly in any desired position, and may be either parallel, taper,
or screwed.
Another part of this invention relates to means for securing in place the different
parts by means of which a spring operated piston expels the lubricant. The upper
scrowed sleeve through which the piston rod passes and which contains the
operating spring, is provided with a nut by means of which it may be locked
in the lubricator.
The accompanying drawings, to which we will hereinafter refer, illustrate
different forms of controlling devices constructed according to this invention.
The same letters of reference are used to indicate similar parts where they occur
in the different figures.
In this
In Figures 1 and 2, which represent respectively a vertical section and an
elevation of part of a lubricator, A indicates the outlet for the lubricant. B is
the plug by means of which the flow of the lubricant is controlled.
instance it is shown with a screwed stem, but it will be understood that it may be
plain and parallel or tapered.
The outer end of the plug is provided with a quadrant or a similar enlarge-
ment C, perforated at suitable points with holes D tapped for the reception of
a screw E This screw may be passed through any one of the holes and its point
be caused to engage with a suitable recess in the body F of the lubricator. The
plug is thus held rigidly in any desired angular position. Instead of forming
the quadrant C with a number of tapped holes for the reception of the screw,
it may be formed with only one and the body of the lubricator may be provided
with a number of recesses for the screw end, or any equivalent construction or
(levices may be adopted.

page_text: In the modification illustrated respectively in elevation and vertical section by
Figures 3 and 4, the plug B is secured in any desired position by means of the
screw K the axis of which is placed in a line parallel with the axis of the plug.
When the plug occupies its required position the screw F is tightened up and
holds it fast. A scale or indicator G may be attached to or formed on the body
of the lubricator so as to assist the adjustment of the plug. The screw K may,
if desired, be co-axial with the plug B.
In the further modification shown in Figure 5 the screwed stem of the plug
carries a coned or other lock nut H which may be forced up against the lubricator
when the plug is adjusted.
Instead of being at the end of the plug nearest to the handle, the lock nut may
be at the other end, which in this case would require to extend through the
outlet A. Figures 6 and 7 illustrate two forms of lock nuts so applied.
In a lubricator in which a spring operated piston expels the lubricant, we pro-
vide means for securing together the different parts. Such a lubricator is illustrated
in Figure 3. L is the screwed sleeve through which the piston rod M passes
and which contains the spring by means of which the piston is operated. This
screwed sleeve engages with and passes through the cover or cap of the lubricator
and by rotating it the pressure of the spring upon the piston may be regulated.
The sleeve is provided with a lock nut N by means of which it is securely held.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. In a lubricator, the combination with the lubricant outflow controlling
device of a retaining or locking device, constructed arranged and operating sub-
stantially as herein before described with reference to the accompanying drawings.
2. Outlet controlling devices for lubricators constructed and arranged substan-
tially as hereinbefore described and as illustrated by the accompanying drawings.
3. In a lubricator of that type in which the lubricant is expelled by a spring
controlled piston, the combination with the screwed sleeve containing the spring
and piston rod of a lock nut or equivalent device, substantially as herein before
described and as illustrated by Figure 3 of the accompanying drawings.
