page_text: Improvements in Lubricators.
PHILIPP HUBERT Engineer 33 Andrassy Strasse Budapest Hungary 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 design essentially consists in the insertion into two cylinders placed opposite
to one another, of two pistons, which execute a slow, alternating movement across
the path of machinery at work, whereby, in one and the same stroke, lubricating
material is sucked into one of the cylinders while it is, on the other hand,
synchronously, forced on to parts that need lubrication.
In this lubricating apparatus, tho reversal of the mechanism as well as the opening
and closing of the suction and forcing pipes, must be done by hand each time the
pistons have come to the end of a stroke.
Although the above named style of reversing takes up no more than a few seconds
of time for every ten to twelve hours, I have deemed it more serviceable from a
practical point of view, to prepare a fresh design making the apparatus as a whole a
piece of self-acting mechanism, and to construct for it a controller
gear, thus
rendering
my Lubricator entirely automatic, the only thing needful being to keep the reservoir
well stocked with a supply of oil.
Such are the improvements forming the subject matter of this present application
for a supplemental Patent, and they will be found plainly figured in accompanying
drawing. Fig. 1 is a vertical, longitudinal section: fig. 2, a horizontal longitudinal
section of the Lubricator: fig. 3 is a cross-section, while fig. 4 is a Detail drawing,
From these drawings, it will be seen that the Lubricator of Patent No. 4096,
March 1887, has been improved in four directions, namely :-
1.) In the connecting of the pistons; 2.) In the reversing gear; 3.) In the driving.
gear; and 4.) In the control mechanisin.

connecting screw arrangement constitutes one single part c only, firinly screwed at
both its ends into the heads of the two pistons. This screw-rod c runs along in a
casing o inwardly screw threaded, which is made to rest in the worm wheel d, and as
it moves in common with the worm wheel d by reason of its internal screw thread
into which the worm of the screw rod works it will produce motion in the screw rod c.
II.
In the Lubricator before patented, the reversing action as already stated, can only
be effected by a mechanism to be operated by hand. For when the pistons have
reached the end of their travel in one direction, and, consequently suction of the oil
at one side, and the forcing of it on to friction parts on the other, have come to a stop,
it becomes necessary to plug the forcing pipe and open the mouth of the suction pipo
on the one hand, and, by a reversal of the process on the other hand, to open the
forcing pipe and plug the suction pipe, because the apparatus in constant alternation
sucks in and forces out on opposite sides. The pins too on the couple of ratchet
wheels must be taken out with the hand meaning that they must be put in and taken
out again to allow of keeping to right or left in its revolution the screw threaded
driving rod that moves the screw rod or shank.
According to the design of the present specification the process of reversing is
effected automatically by means of the mechanism hereinunder described.
On the body of the Lubricator there is fitted to one side of it a three-joint
part ppl p, so put together that it will turn round the four points 1, 2, 3, 4, and
that the p portion thereof will execute a movement from right to left. There are
two extensions p* p* of this articulated part reaching towards the interior of the
apparatus. Supposing now, the coupled pistons to have finished their stroke in one
direction, then that one of the two pistons which has worked to produce suction, as,
for instance, the piston b. in Fig. 2, will come up with its head against extension p³, in
consequence of which the articulated part p p p² will bodily perform a movement
forming a parallelogram of the connecting lines of the 4 pins,,, that is to say,
portion p of the said jointed part will, in the instance selected as an illustration, go
through a short movement to the left. This portion p¹ is notched at t, where a pin w,
runs in. If now, p' moves as described, one of the side walls of its notch t will press
against the central axis w, whereby the latter will be made to give in the same direction.
Above the pin w, there is fitted to the lateral wall of the apparatus, a shaft (pin) v,
which forms the pivot or fulcrum of a lever s, provided with a balance weight u. So
soon as the pin w, has been so far driven to one side that it comes to be somewhat out
of the perpendicular in relation to pin v, then the levers influenced by the balance
weight u, will drop towards the opposite side. Simultaneously, the pin w, will impinge
against the parts at the notches y y of rod h h whereby this rod too is moved on
one side. At both ends of rod h A', there is attached a cone e which two cones each
lie enclosed in a close casing A A¹ provided in one part with a rounded sunk
concavity f.
The cone here as a consequence of the sunk concavity assumes an annular form,
which opens and shuts, in manner following, the suction and forcing pipes opening
into the casing. When piston b acts as a sucker, the cone e. will lean against the
side a of casing A, whereby pipe B coming from the oil cistern will be made to
open (discharge) into the sunk cavity of the cone. This brings about the connection
of the two pipes, and in consequence of the suction of piston b, the oil will get into
the cylinder. When piston 6 has completed its suction, and this rod has been pushed
to the left by the influence exerted by extension p³ then cone e will lean against the
side of casing A, leaving the pipe c open, while pipe B will be closed as it gets to
lie in the sunk cavity f. Now the oil, owing to the pressure of piston b, will be carried
through pipe c into the casing and thence through the opening, that is to through
pipe D, to all the parts liable to friction. Exactly the same arrangement is planned
for the opposite side of the apparatus in casing A', where the suction and forcing
say,

page_text: pipes, by means of the displacing movement of rod h will alternately he opened and
closed.
The pistons are started working by the rotation of a rod E with a worm on it, and
the cogs of wheel d work into the grooves of the worm. To produce rotary
motion two wheels g g having saw teeth with opposite set, are fitted on shaft. F, as
also a propellor arm G to which are attached, capable of rotation, the lock bolts / 1¹
that reach in between the saw-teeth. Both the ends of the propellor arm G are
fastened with a ring H on which one of the points of said ring lie opposite to one
another, the lever arm Ti can be firmly fixed by means of screws, which (said lever
arm) can be connected with any alternately moving part of the machine, that is to
say, when the alternating motion of the relative part of the machine is horizontal
to the position or '; but if said motion be vertical, then to the position jª or j³._The
arm G takes on said alternating motion, but rod owing to the action of the wheels
with lock-bolts and saw-teeth can move in one direction only, that is, only till the
stroke of the pistons has reached the goal. The piston that has been engaged in
doing duty as a sucker, will bump, as before stated, its head against the extension p³
or else p and reverse the lever s. This levers, has from its pivot downwards a
prolongation and a rivet is fitted to its lowermost point which rivet rests against
the posterior lateral wall of the adjustable prism k attached to the pieces xx.
ends of the posterior lateral wall of said prism k are each fitted with a nose-shaped
protuberance ii. Now when the levers inclines towards the opposite side, the
rivet z will reach one of the extremities of the prism k, touch its protuberance (i or i¹)
and lift up this extremity of the prism moving around E. But, owing to the two
rivets K K attached to the outside of this.prism and as a consequence of the movement
before described, one of these K or K' rivets will raise one of the lock bolts / or /',
whereby it is cast off the wheel with the saw-teeth, while at the same instant, the
other or second rivet depresses (lets down) the lock bolt situate on the opposite side,
bringing it into connection with the second saw-toothed wheel. Thus the reversing
process is accomplished, and as the worm rod will now be receiving the contrary
rotary motion, the pistons will move in the opposite direction, until the second piston
again reaches the extension p³ or p₁ as the case may be, thus bringing about the
reversing action on the opposite side.
Both
So as to insure the uninterrupted flow of oil and continuous lubrication, to be
certain that the reservoir for the oil is not exhausted, there is fitted to the upper
part of the Lubricator a check arrangement. The oil on its way to the friction
surfaces must go through one of two circular bent pipes L L and into the small
channels M. M. and first through a glass receiver filled with water when it will thence
continue its course along the connecting pipe. Any possible retrograde pressure is
obviated by a check valve P.
Over the apparatus at the openings there are two plug screws in lieu of the former
figured pieces (of previous Patent)."
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is
1. The improvement in the connecting of the pistons consisting of the screw-rod
(shank) c made of one piece, and which is firmly screwed on to the piston and is set
in motion by the rotation of the screw threaded casing (shell) o lying inside of worm
wheel d. This improvement, besides, is introduced by way of security because at the
end of the piston stroke, the mechanism as a whole, and the casing with the pistons,
takes an endlessly rotating motion, until reversing occurs.

page_text: 2. The automatic reversing mechanism in this apparatus in consequence of which
the pistons themselves are driven against the inward reaching prolongations p³ p¹ of
a jointed part p p¹ p² pushing away said jointed part thus bringing about the alternate
opening and shutting of the suction and forcing pipes along a horizontal rod h h' and
of the cone e attached to their extremities and enclosed in the casings A A¹; and,
furthermore, effect by pushing away the said jointed part by means of a lever s. of a
prism pushed aside by the latter and of the rivets K K' thereon, the release of tho
lock bolts catching in between the teeth of a wheel, the teeth of which are set in
a contrary direction, thus producing the to and fro motion of the pistons.
3. On the propellor G of this apparatus the adoption of the ring H to allow of the
acting lever i which is to be connected with the working Machinery, being put on
in any direction of the course of said working Machinery.
4. The use of a special check mechanism L. M. N. P. in said Lubricating
Apparatus.
