Improvements in Mechanism for Lubricating Machinery.
We, ACHILLE DRUCBERT and NAPOLEON DRUCBERT, both of Boulevard
Henri IV, Paris, in the Republic of France, Manufacturers, 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 :-
This invention relates to mechanism to be driven by the machine which is to be
lubricated and it consists of certain devices combined with a pump whereby only
the quantity of lubricant necessary is supplied to the parts to be lubricated.
The drawings hereunto annexed will help to describe and illustrate the improved
devices, Fig. 1 being an elevation of an oil reservoir pump and valve box,
Fig. 2 side elevation of the improved mechanism arranged on base or bed plate A.
bis the chain which imparts movement to the lever B, said chain being attached
to any suitable part of the engine or machine to be lubricated, capable of giving
said chain an up & down motion. On the bed plate A is fixed a standard E in
which is pivoted the lever B operated by the chain b. By its upward movement
the lever B causes the pawl C furnished with a weight C to be engaged in and
operate the ratchet wheel D, this wheel is supplied with studs O (as many as
needed), which serve to press down the pump bar G pivoted at a on the standard H
fixed on the bed plate A. The standard E is furnished at its upper part with a pawl F
kept constantly geared in the wheel D by a spring p as shown. At c on the bar G
is articulated a piston rod I of a pump J which communicates with the reservoir K
on one side by means of the pipe e and with the valve box L on the other. The
valve box is furnished with a valve M and an outlet pipe m, communicating with
the machinery to be lubricated. At the extremity of the pump bar G is a counter-
weight N for restoring the bar to its original position after every movement and
stroke of the piston I, the force of this movement can be adjusted or regulated by
placing the weight in one or other of the holes i and the amplitude of movement by
the rod g'. The movement of the lever B is controlled and regulated by means of
the screwed rod g which takes a bearing on the bed plate A as shown. The pump J
may be arranged horizontally and an excentric and connecting rod used in lieu of
19
the ratchet wheel.
The working of the improved devices is as follows:
The chain is fixed or attached to any convenient part of the machinery proper
able to produce an up and down movement of it and of the lever B and its pawl C
which turns the ratchet wheel D. This ratchet wheel is revolved until one of its
studs o operates and moves the lever G which thereby lifts the piston I of the
pump J which draws the oil into the pump cylinder. When the stud o leaves the
lever G the latter will be moved back by the weight N, the oil will be driven
within the valve box L and from there through the pipe m to the part to be
lubricated.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
The combination of a pump with a lubricating reservoir and supply pipe worked
by the machine to be lubricated, the devices for operating and causing the lubrication
consisting of a lever and pawl geared into a ratchet wheel supplied with studs or
pins serving to work a counter weighted bar attached to and capable of operating

spot to be lubricated.
