Complete Specification Accepted, 21st Sept., 1888
I, ERNST KÖRTING, machine manufacturer, residing at Hanover, Kingdom of
Prussia, do hereby declare the nature of this invention to be as follows:-
My invention relates to injectors in which the starting-cock and the steam-valve are
so connected together that, when the latter is opened, the former is closed, and
vice-versa, and the object of the invention is to provide new and simple means whereby
the said connection is produced.
For this purpose the cock is arranged with its axis at a right angle to the axis of
the apparatus, and the key of the plug of the cock is made with a cam-groove in it.
To the stem of the valve is fixed, by means of a cross-piece, a sliding bar, guided
parallel to the axis of the apparatus and having a pin engaging in the aforesaid
groove. The parts are so arranged that, when the cock is open, the valve is in its
closing position, and that, when the plug is turned for closing the cock, motion will
be transmitted through the cam-groove of its key and the sliding-bar to the valve,
so as to open it.

I, ERNST KORTING, machine-manufacturer, residing at Hannover, Kingdom of
Prussia, 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 injectors in which the starting-cock and the steam-valve are
so connected together that, by the act of opening the latter, the former is closed and
vice-versa, and the object of the invention is to provide new and simple means whereby
the said connection is produced.
For this purpose the cock is arranged with its axis at a right angle to the axis of
the apparatus, and the key of the plug of the cock is fitted with a cam-groove. To
the stem of the valve, movable lengthwise to the apparatus, is fixed, by means of a
cross-piece. a sliding bar, having a pin which engages in the aforesaid groove. The
parts are so arranged that, when the cock is open, the valve is in its closing position,
while, when the plug is turned for closing the cock, motion is transmitted through
the cam-groove of its key and the sliding-bar to the valve so as to open it.
On the annexed sheet of drawings Fig. 1 shows in sectional elevation an injector
provided with my improvement. A is the plug of the cock and C key or handle of
the same, shown by Fig. 2 in back view. The said key has near its boss C a flat
extension, on the rear side of which is formed the cam-groove D. B is the steam-
valve, having the stem I, to which is fixed, by means of the cross-piece H, the bar F,
arranged to slide parallel to the axis of the apparatus in the guides G, and carrying
the pin E, which projects into the groove D. Preferably this pin is provided with a
roller. It will readily perceived that, by means of this arrangement, a motion of the
key or handle C produces simultaneously a rotation of the plug A and a vertical
motion of the valve B.
The described device may be modified by substituting for the groove D a rib
forming a cam, and providing the bar F with two pins or projections that straddle
the said rib. Moreover, the cam-groove or rib may be on the bar F while the
projection or projections engaging therewith are on the key or handle C.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
In an injector, the combination, with the steam-valve, of a starting-cock arranged
transversely to the line of motion of the valve, a sliding-bar being parallel to the
said line of motion and fixed to the valve, and a key fixed to the plug of the cock, the
key and the sliding-bar being in engagement with each other by means of a cam-piece
arranged upon one of them and a projection or projections formed upon the other part,
substantially as and for the purpose described.
Dated the Thirteenth day of August 1888.
