Description
F. GREINER. INDICATING DEVICE FOR INTERNAL comausnom ENGINES.
APPLICATION FILED MAY 8. I913.
Patented Bea 28,1915.
s'rarns PATENT orrio FRIEDRICH GREINER, OF SCHWABISCH-GMU'ND, GERMANY, ASSIGNOR T0 OTTO SCI-ILIGK, OF BERLIN, GERMANY.
INDICATING DEVICE FOR INTERNAL-COMBUSTION ENGINES.
To all whom it may concern:
Be it known that I, FRIEDRICH GREINER, of Schwabisch-Gmiind, a subject of the King of Wurttemberg, and whose post-office address is 8 Derkstrasse, Schwiibisch- G-miind, near Stuttgart, Kingdom of Wurttemberg, German Empire, have invented a new and useful Indicating Device for Internal-Combustion Engines, of which the following is a. specification.
Thisinvention relates to an indicating device for internal combustion engines and it consists chiefly in connecting the combustion or explosion chamber of the cylinder or in case of 'a plurality of cylinders the combustion or explosion chamber of each cylinder to a manometer and interposing a "suitable non-return valve in the connection. valve enables the pressure prevailing in-the explosion chamber readily to enter the manometer but prevents it from rapidly escaping therefrom so that when the engine is running the manometer constantly indicates the maximum pressure in the explosion chamber without substantial fluctuations of the indicator.
The invention, moreover, consists in a particular arrangement of the indicating device of the manometer.
The device forming the subject of this invention is destined to afford a constant control over the motors of automobile and flying machines and is adapted particularly in flying engines safely to locate the failure of individual cylinders and of its cause and to enable such defects to be immediately removed.
The invention is illustrated by way of example in the accompanying drawings, in
which,
Figure 1 shows a constructional form ofthe novel device in which the manometer and the motor are separately arranged. Figs. 2 and 3 show a form of the device with four manometers for 'a motor having four cylinders, Fig. 2 being a front vieu and Fig. 3 a sectional view on the line 33 of Fig. 2.
In the example shown in Fig. 1 a socket d is screwed into the cylinder. This socket (Z is provided with a casing g of a non-return ball valve 2 which is interposed in the connection. This valve is subjected to the influence of a weak spring f. This valve, moreover, enables the pressure of the ex- Specification of Letters Patent.

plosion chamber of the cylinder to readily enter a manometer a connected with the valve casing g by means of a conduit n, whereas the escape of the pressure from the manometer takes place by leakage around the ball valve during a period of about a second or fraction of a second. In regular running of the engine, therefore, the ma nometer constantly indicates the maximum pressure prevailing therein.
The manometer a being arranged separately from the socket d and being connected therewith by way of the conduit n, the indicating device may be arranged in close proximity to the driver, for instance on the splash-board. The manometer indicator 8 is covered by a face plate or cover r provided with a slot w, so that only the point 0 is visible in the slot w containing the dial. As soon as the indicator registers with a hole t of the cover 1" not only its point but also a further portion of its bodybecomes visible so that its position may be observed from a relatively long distance particularly if a .red coating of paint is applied to the indicator.
The face plate or cover plate 7' is rotatable as shown clearly in Fig. 3, so that the hole I? may be adjusted by hand to any desired point of the dial.
If the motor has a plurality of cylinders or if there are two motors the manometers may be arranged in a common casing, as shown in Fig. 2. If, for example, the pressure on which the motor gives the desired regular effect is between 20 and 25, all holes t are adjusted to this point, and all holes -As soon as one of the cylinders alters its regular work the driver of the autocar or of the flying machine can see. at a glance that one of the cylinders and also which of the cylinders gives the irregular pressure, the hole of the corresponding manometer showing instead ofv a red circle a partly or wholly White circle. This means of control is of most importance when running with fast speed or when flying overland.
Vhat I do claim as my invention and desire to secure by Letters Patent of the United States, is:
In an indicating device for use in internal combustion engines the combination of a manometer connected to the combustion or explosion chamber of the corresponding motor cylinder with a non-return valve interposed in the connection between the manometer and the corresponding cylinder, an indicator of the manometer and a face plate covering the dial of the manometer but having" a slot and a hole, a portion of said indicator being visible at all times through said 10 slot and a further portionof said indicator being visible through said hole when the indicator reaches a predetermined'position.
In testimonv whereof I have hereunto set my hand in presence of two subscribing witnesses.
FRIEDRICH GREINER.
