COMPLETE SPECIFICATION.
A New or Improved Weight or Gravity Motor.
I, JULES LINTZ, of Bouzonville, Lorraine, in the Empire of Germany, 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:-
This invention relates to motors worked by weight or gravity and has more
particularly, reference to a motor worked by a weight and designed more
especially for actuating all kinds of machines which consume but little power,
and have a rotary motion as is hereinafter described.
In the accompanying drawings which show by way of example one form of
construction of the invention, Figure 1 is a diagrammatic view of the general
arrangement of the motor.
Figure 2 is an elevation of the drum around which is coiled the cord that
supports the driving weight.
Figure 3 is an elevation of the parts for transmitting the motion of the motor
to a machine which is to be driven.
Figure 4 is a detailed view of the abutment of the endless screw that terminates
the train of gearing upon which the driving weight acts.
Figure 5 is an elevation of one of the brakes.
Figure 6 shows in elevation the arrangement of an intermediate pulley tackle
between the driving weight and the train of gearing.
The apparatus comprises: A weight supported by a cable passing in a pulley
tackle; a train of gear wheels for multiplying the speed; and an intermediate
transmitting device between the train of gear wheels above mentioned and the
machine to be driven. Upon the axle g of the first wheel of the train of gearing
above mentioned there is keyed a drum f round which a steel cable, carrying the
driving weight is adapted to be coiled by means of the above mentioned pulley
tackle. The train of gear wheels is mounted on a suitable frame o, shown in
dotted lines in Figure 1, for the sake of clearness of the drawing. Upon the
shaft 9 there is also keyed a ratchet wheel f¹, which wheel can turn freely on
the shaft g. This wheel is provided with a pawl d, which is pivotted to one of its
arms and which is held in engagement with the ratchet wheel fl by means of a
coiled spring e. The train of gear wheels with which the wheel a engages,
terminates in an endless screw b, b, the end of which on the side on which it is
pushed by the action of the wheel engaging therewith, is pivotted on an abutment
plate which is interchangeable, and is made of hardened and polished steel,
and is capable of being readily removed, as it is simply fixed by means of screws
to the corresponding bearing. At the other end of the axle of the endless screw g,
there is keyed a pulley c. An intermediate device for transmitting motion is
arranged in proximity to the framing of the aforesaid train of gear wheels.
This device consists of a frame carrying a bearing in which can rotate a shaft p
upon which are keyed, a heavy fly wheel, a small pulley driven by means of a
belt from the pulley c, and a pulley k which serves to transmit the motion to the
machine to be driven. Between the drum and the driving weight x, the cable is
coiled upon a pulley tackle (Figure 6). The cable passes first around the pulley b',
then to the pulley c", to the housing of which there is suspended the driving

page_text: weight x. The cable then passes to the pulley & whence it is bent successively
around the pulleys of the pulley tackle. The top pulleys are mounted firmly on
stationary supports in any suitable manner to suit the local conditions. The
lower pulleys turn in a double casing which is connected to the axle of the
pulley . The end of the cable is fixed at m to the support of the upper pulleys.
The apparatus is provided with two similar brakes, one of which is shown in
elevation in Figure 5. One of these brakes acts upon the shaft of the fly wheel,
whilst the other brake acts upon the shaft of the wheel which gears with the
endless screw. A flat wheel is fixed on the shaft of the fly wheel or of the
aforesaid wheel. Two legs of a tongs C¹, C, are pivotted at and each ends at
its free end in a fork in which can freely turn a small roller 6" of caoutchouc
mounted on a steel axle. A screw r serves to close the tongs when desired for
the purpose of putting on the brake, and a coiled spring serves to push the legs
apart when the brake is taken off. The brake is supported by the axle of the
pivotted joint z. In case of necessity, there may be employed a governor acting
by means of the axle of the fly wheel or by means of the endless screw.
apparatus operates as follows:-After the weight has been raised with the aid
of a crank handle or other means, engagement is effected between the pawl
and the ratchet wheel f¹. The motion imparted to the drum by the action of the
weight is transmitted to the endless screw b, b, and by means of the pulleys c
and to the shaft p. The pulley tackle is employed for the purpose of rendering
the travel of the weight as short as possible, in order that the apparatus shall
not require too great a space.
The
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, declare that what I
claim is:-
(1) A motor worked by weight or gravity designed to actuate all kinds of
machines that consume but little power, and have a rotary motion, characterised
by a weight supported by a cable passing over pulley tackle, and wound upon a
drum which transmits the motion through the medium of a train of gear wheels
ending in an endless screw, to a transmission pulley actuating by means of a belt
and a pulley an intermediate shaft upon which there is keyed a fly wheel and a
pulley which transmits the motion to any machine which is to be driven, the
motor being provided with two brakes, one of which acts upon the shaft of the
wheel gearing with the endless screw, whilst the other brake acts upon the shaft
of the fly wheel, there being also arranged if desired a speed governor acting
either upon the endless screw or upon the shaft of the fly wheel; the first gear
wheel being mounted loose on the axle of the drum so as to allow of raising
the weight by means of the rotation of the drum in the opposite direction without
affecting the train of gear wheels, whilst the axle of the drum likewise carries a
ratchet wheel in which there is maintained in engagement by means of an
actuating spring, a pawl pivotted to one of the arms of the first toothed wheel
for the purpose of driving it when the drum turns under the influence of the
unwinding of the cable in such a manner that the train of gear wheels is only
subjected to the influence of the fly wheel during the winding up of the weight,
as set forth.
(2) A new or improved weight or gravity motor substantially as above
described and shown in the accompanying drawings.
