"A SELF-ACTING PUMP FOR WINDING AND PUMPING, ALSO FOR MEASURING
LIQUIDS, AND FOR OTHER USEFUL PURPOSES."
This Invention relates to a self-acting pump for winding and pumping, also for
incasuring liquids, and for other useful purposes, and consists of a cylinder in which
a piston is fitted, having a rocking circular motion imparted to it by a crank on
which it is arranged. The piston is slotted, and a cross head or block is in this
slot. The block is in connection with a fixed plate, and forms with a ball on its
end a knuckle or ball joint. The fixed end of the plate is in a pipe, through which
air, gas, water, or other fluid or liquid can pass from one sido of the plate to the
other, the plate passing through an aperture in the cylinder in which it has an
amount of play. In action the air, gas, water, or other fluid or liquid passes along
the entrance pipe into the cylinder on one side of the plate and presses against the
piston, forcing it to follow its course under the rotation of the crank and its shaft,
to which counting or other mechanism can be attached and driven. The air, gas,
water, or other fluid or liquid passes round the periphery of the piston and finds an
outlet from the opposite side of the plate along the outflow pipe.
The accompanying Drawing represents the apparatus. A is the cylinder, B the
piston, R the cross head or block, S the knuckle or ball joint, d the plate, O the
entrance for the air, gas, water, or other fluid or liquid, and O' the outlet for the
same; a is the shaft and b the crank.

page_text: B, B', motor discs, being at the same time true cranks forming pistons, whence the
denomination of the apparatus motor cranks. M, M³, are cranks having respectively
their centres at band when there are two coupled systems; E is the orifice of
the entry of the fluid; F is the exit orifice; O is the centre of oscillation of the
guide (coulisseau); d is the fixed diaphragm.
In action if one causes any fluid or liquid to enter through the orifice E under
pressure the fluid will impart to the discs B, B', an oscillating circumferential
movement like the figure 8, resulting from two combined movements, the one
oscillatory around the fixed axis o and the other circular drawing the cranks M, M¹.
One can in a same cylinder put a crank with a simple disc or with several discs
combined, so that the effect is uniformly spread. The parts animated with one
movement of rotation are provided with independent rings Z, and can turn freely
upon their axes; their object is by their automatic rotation the displacement of
the lubricating material.
At this point I may remark that for very great speed I introduce the lubricating
liquid by the centre of the shaft in order to avoid the inconvenience of the centri-
fugal force, which becomes then in this case a very energetic agent in the drawing
of the lubricating liquid. When I wish to attain considerable speed I make the
crank shaft fixed and I turn the cylinder and the disc, the one drawing the other;
there are then two continuous circular movements on different centres but of
constant direction. I reserve to myself expressly this modification, for which it is
sufficient to introduce the fluid by a box or passage concentric to the shaft.
Expansion (detente).-This machine without the addition of any piece can act
expansively (à detente) at half course by the oscillation of the swivel (rotule),
shewn at Figure 3.
Variable automatic expansion (detente).-I can also produce combined with the
preceding arrangement a variable expansion (detente) by a regulation based upon
a special principle of dynanometer.
Figure 6 shows the motor shaft formed in two sleeves connected by dynanometer
spring. The sleeve L commands the circular expansion drawer D. At rest the
opening of the orifices permits only a slight admission, and as soon as the fluid is
introduced the motive crank is put in motion, stretches the dynanometer spring
corresponding to the work of resistance, and regulates thus the degree of expansion
in direct proportion to the effort.
I claim this application of a new principle completely opposed to the regulators
with centrifugal effects, and which I represent by another arrangement at Figures 7,
8, and 9, which show a system of expansion composed of a circular distributing
slide drawn by the extremity of the shaft of the machine. In this slido a little
piston R is formed of bronze actuated by the regulator, and which opens or closes
according as needed the orifices O, O. Here the regulator is simply composed of
two sectors M, N, held by a spiral spring. There are two sectors separating under
the action of the spring, which cause the extremity P of the little piston R to move.
There remains to describe the appropriation of this apparatus in case, for example,
of drilling and picking (fraisage) for all works, and in particular for the works of
mining, such as piercing galleries for the raising and hacking of coal, which is one
of the numerous applications of the motor.
Sheet II The fixing of the motor, Figures 10 to 13, takes place in the following
manner by a planed and toothed girder K serving as a bench or regular base :-In
this girder a toothed frame U engages for an endless screw, moveable longitudinally,
taking the profile of the girder and able consequently to slide with gentle friction
upon the said girder. The turning plate T, of forged iron, is armed with an axis T
of a worm G, G, intended to receive two pieces, first, an endless screw V gearing
with the toothed frame U; 2ndly, the oscillating frame X upon which the motor
slides. This oscillating frune of the axis of the endless screw V (see Figure 10)
participates equally in the circular movement of the turning plate T, actuated by
this same endless screw. The toothed frame being fixed circularly is then the screw,
which, by its rotation, will be drawn and with it the plate turning upon the oscil-

page_text: lating frame. On the other hand the pinion P cannot displace the whole in one
longitudinal direction by its action upon the rack of the girder. And lastly, as the
motor can itself slide upon the oscillating frame along screws H, H, actuating one
of them at Y, it will result that the shaft of the motor and consequently the motor
itself can bave 1st, the normal movement of perforation or straight advance;
2ndly, the perpendicular longitudinal movement or first; 3rdly, an oscillating
movement perpendicular to the longitudinal axis; 4thly, an oscillatory movement
parallel or oblique in relation to its base, that is to say, from right to left in relation
to the straight advance. The apparatus possesses then all the movements necessary,
from right to left, from above to below, oblique, and longitudinal.
It is understood that I reserve to myself to construct my motors in any metal
and size, single or coupled in any manner; and I reserve to myself also to apply it
either as a motor or as a compressor or force pump, or as a ventilator, in the same
cases and circumstances where the above-named apparatus are applicable.
In witness whereof, I, the said Claude Ludovic Taverdon, have hereunto set my
hand and seal, this Fourth day of November, One thousand eight hundred
and seventy-six.
