Improved Apparatus for Stopping Steam and other Engines from
Different Parts of a Factory or other Building.
I, CHRISTOPH GLADE, of Dreye, near Bremen, in the Empire of Germany,
Gentleman, do hereby declare the nature of this invention to be as follows:-
My invention relates to means for enabling a steam or other engine by which
the machinery of a factory or workshop is driven to be stopped from any room or
rooms or part or parts thereof.
According to my said invention a shaft passes through the workrooms which shaft
can be thrown into operation by means of lovers situated at different places. By the
movement of the shaft a crank fixed thereon acts upon an arrangement of levers
A second crank is also fixed on
which can be modified according to circumstances.
the shaft, one end of which works in a slot of a bell-crank lever which latter is also
connected with one end of a rod. The other end of this rod is formed with an eye
for guiding a shaft which is suspended by means of a cup and ball bearing. Whilst
the projection on the first crank which supports a weighted lever moves from under the
said lever, the second crank operates the bell-crank lever so as to bring a gear
wheel fixed on the suspended shaft into engagement with a gear wheel fixed on the
spindle of the steam or other valve.
On the weighted lever is a toothed segment gearing with a bevil wheel on a short
shaft, the latter also carrying a second bevil wheel engaging with a corresponding
wheel on the suspended shaft so that as the weight falls it will communicate motion
to the gearing for operating the valve.
According to a modification of my invention a latch on the main shaft operates a
bell-crank lever through a rod to throw out of gear a pin which supports the weight.
A cord connected with the weight operates a roller on the valve spindle so as to close
the valve.
According to another modification the weight is held in position by means of a
tongue, which is operated by revolving the shaft. Here again a toothed segment is
arranged on the weighted lever which operates the valve-spindle through suitable
Gearing

page_text: According to another arrangement a bearing piece is operated by means of a cord
which bearing piece moves the pin which supports the lever with its weight sideways
so as to close the valve. The cord can be operated by revolving the shaft whereby
pins which hold a spring in compression are turned over thereby causing the sliding
valve to cut off the supply of steam.
The purpose herein before described is further and more simply effected by means
of a continuous wire, in which case a shaft is necessary only in the engine room.
For promptly stopping the steam engine a brake can be arranged in such a manner
that by the rotation of the shaft the brake can be applied to the fly wheel.

Different Parts of a Factory or other Building.
I, CHRISTOPH GLADE, of Dreye, near Bremen, in the Empire of Germany,
Gentleman, 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 :-
My invention relates to means for enabling a steam or other engine by which the
machinery of a factory or workshop is driven to be stopped from any room or rooms
or part or parts thereof.
My said invention consists essentially in combining with the regulating or stop
valve of an engine or with an auxiliary valve, a weight or spring either directly or
indirectly, in such a manner that when the said weight or spring is released it will act
upon the valve to close the same.
In the accompanying drawing,
Figure 1 is an elevation showing an arrangement of mechanism for closing the
regulating valve by means of a weight; and
Figure 2 is a view of a detail.
Figures 3 and 4 are views illustrating different modifications for closing the valve by
means of a weight.
Figure 5 is a view, drawn to an enlarged scale, of a detail of the mechanism shown
in Figure 4.
Figure 6 is a view of a modification where a weight is adapted to close an auxiliary
valve, and
Figure 7 is a view of a detail of the same.
Figure S is a similar view to Figure 7 but showing the arrangement of a spring
for closing the auxiliary valve; and
Figure 9 is a view of the valve and spring drawn to an enlarged scale.
Similar letters of reference indicate corresponding parts in all the figures.
a is the regulating valve, 6 is the valve stom, and c is the actuating weight.
d is a shaft which passes through the workshop and which is adapted to be thrown
into operation by means of levers or other attachments situated at different points.
As shown in Figure 1 the weight c is arranged to act upon the valve through the
medium of the gear wheels e, fone of which is secured on the valve stem b, while
the other is secured to a shaft g. The weight c, which is carried on a lever h mounted
in the bracket i, has secured to it a segmental rack j engaging with a pinion on a
countershaft k. The latter also carries a bevil pinion adapted to engage with a
pinion on the shaft g. With this arrangement the weight c when released will
impart motion to the valve spindle to close the valve.

page_text: The weight is normally supported by a crank arm or catch m on the shaft d and
is released when the said shaft is rotated.
In order that the gear wheel shall only engage with the wheel e when the engine
is to be stopped, so that at other times the valve may be operated by hand, a crank
arm or lever is also fixed on the shaft d, one end of which works in a slot o in one
arm of a bell-crank lever o¹ the other arm of which is also connected with one end of
a rod pas shown most clearly in Figure 2. The opposite end of the rod p
is formed with an eye through which the shaft g, which is suspended by
means of a cup and ball bearing passes. With this arrangement when the catch m
which supports the weighted lever moves from under the said lever, the lever n
operates the bell-crank lever o' so as to bring the gear wheelf fixed on the
suspended shaft into engagement with the gear wheel e fixed on the spindle b of the
valve.
According to the modification of my invention shown in Figure 3 the weight is
connected with the valve spindle through the medium of a cord y, which, when the
valve is open, is coiled more or less upon a roller g. The weight is normally sup-
ported by a pin or bolt which is connected to one arm of a bell-crank lever the
other arm being connected by a rod 2 to a lever n on the shaft d. When the bolt is
withdrawn owing to the movement of the shaft d, the woight causes the unwinding of
the cord from the roller, thereby closing the valve.
?"
In the modification of my invention shown in figure 4, a toothed segment j is
arranged on a weighted lever, as in Figure 1, the motion of the said lever being
transmitted to the valve spindle through suitable gearing as shown. The lever is sup-
ported upon tonguess, snt the ends of toggle arms t, t, as shown in figure 5, the said
toggle arms being carried upon a fixed pivot t¹ and connected at their upper ends
by a link to the lever in such a manner that when the said lever is depressed owing
to the movement of the shaft d the arms t, t will be opened causing the tongues &, sto
separate and drop the lever h.
As shown in Figure 6 the weight e is arranged directly upon the stem of an
auxiliary valve a¹ and is normally supported by a sliding bolt or pin in the same
manner as shown in Figure 3. To the bracket carrying the bolt is secured a lever v,
which passes through a slot in the said bolt and serves to move the same sideways. A
cord is attached at one end to the lever and at the other end to the lever n on tho
shaft d, and passes around a pulley 3, as shown most clearly in Figure 7, so that
when the cord is tightened by the movement of the shaft d the bolt will be withdrawn
and allow the weight to close the valve.
In the modification illustrated in Figure $ a spring wis substituted for the weight
and is arranged to close an auxiliary vavle a.
As shown the spring at one end bears
against a stirrup secured to the body of the valve whilst the other end bears upon a
plate y secured to the sliding valve stem. Tho valve is kept open by two pivotted
arms z, Figure 9, which support the plate y against the pressure of the spring w.
The cord is attached to the arms in such a manner that when the shaft d is rotated
they will be pulled away from beneath the plate y so that the latter with the valve
stem is free to descend under the action of the spring to close the valve.
I wish it understood that the modifications of my invention herein before described
are only given as examples it being obvious that the details of construction can be
varied without departing from the nature of my invention.
In practice find it very advantageous to arrange the shaft d in the engine room
only, and to arrange in connection with it a cord or wire extending to the different
points at which it is desirable to provide for effecting the stoppage of the engine.
For promptly stopping the steam engine a brake can be arranged in such a manner
that by the rotation of the shaft the brake can be applied to the fly wheel.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the samo is to be performed 1 declare that what I
claim is:-
11
1. The combination with the regulating or stop valve of an engine or with an

page_text: auxiliary valve. of a weight or spring arranged in conjunction with the valve and so
supported that it can be released from one or more parts of a factory or workshop,
substantially as, and for the purpose, described.
2. The manufacture and use of the improved apparatus for stopping steam and other
engines from different parts of a factory or workshop, substantially as described with
reference to Figures 1 and 2 of the accompanying drawing.
