HEINRICH MEINECKE junior of the City of Breslau in the Kingdom of Prussia
and German Empire. IMPROVEMENTS IN RAISING APPARATUS, ALSO APPLICABLE
TO STEERING APPARATUS,
This Invention relates to improvements in raising apparatus also applicable to
steering apparatus and consists principally in a brake or catch arrangement, which
said brake or catch arrangement causes the weight to remain stationary in any
position when the crank or handle is involuntarily let go..
The principal novel features in the present invention are the employment of two
pullies connected to one another by means of an endless chain, one of which said
pullies is tightly keyed to the end of the barrel axle and the other runs loosely on
the axle of the handle or crank; and the arrangement of a peculiarly shaped
crank or handle, which effects the connection between the axle of the said handle
or crank and the loose chain pulley on the same.
The barrel is arranged to run loosely on its axle or shaft upon the end of which
said shaft or axle a chain pulley is keyed. This said chain pulley, is, by means of
an endless chain, connected to another chain pulley, which latter pulley runs loosely
on the axle of the crank or handle.
When the axle of the handle or crank is turned backwards, the same is brought
into connection with the chain pulley of the barrel axle by means of the peculiarly
shaped handle or crank employed.
This said crank or handle consists of a piece of metal tightly fixed on the crank
axle, which said piece forms the bearings for a pivot, upon which a double arm is
arranged to turn.
The shorter part of this double arm acts as a pawl, and directly the handle is let
go, it grips by means of the action of a spring into the ratchet teeth of the chain
pulley on the crank axle and in this manner any further backward or lowering
motion is effectually prevented
When a weight is being raised the spring is pressed together, the shorter part of
the double arm bears against a pin and does not come into contact with the teeth.
As upon the backward or downward motion the barrel or drum has to be driven

page_text: rapidly round from the crank-axle an automatic running down of the weight
cannot occur provided the parts are correctly proportioned.
The application of these improvements to steering apparatus is as follows:
For this purpose no further parts than the wheels and axles actually necessary
for effecting the movement of the rudder are employed; but these wheels are
connected with one another in such a manner that they hold the rudder in any
and every position.
The wheel arrangement consists principally of the hand or steering wheel, the
pinion of which gears into the spur-wheel of the counter shaft.
The pinion of this said counter shaft gears into a spur wheel, which is fixed on a
hollow axle, which said hollow axle revolves loosely on the axle or shaft of the
hand or steering wheel. The hand wheel is turned in the same direction as the
rudder.
This arrangement prevents any unintentional or undesired movement of the
hand or steering wheel from the rudder and renders the steering very easy.
When the parts are rightly proportioned, the friction to be overcome with this
sytem will not be greater than that of the screw steering arrangements.
