8 Claims.
This invention relates to devices'for automatically stopping an engine and, more particularly to devices for stopping the engine ofan automobile or like vehicle after a predetermined period of idling of the engine with the transmission gears, in neutral or disengaged positions.
Heretofore, there have been proposedvarious devices for accomplishing this general purpose to prevent the generation in closed garages and the like of quantities of carbon-monoxide gas sufficient to cause injury or death to occupants of an automobile, and also to prevent unnecessary waste of fuel.
An object of the presentv invention is to provide an improved simple and efiicient device for accomplishing the desired purpose.
Another object of. the invention is to provide a device of this'nature which may be readily incorporated in an existingautomobile structure.
Other objects and features of the invention will appear as the description proceeds. In the drawing:
Fig. 1 is a diagrammaticillustration showing a device constructed in accordance with the invention in contemplated association with certain automobile parts;
Fig. 2 is a detail sectional view of thedevice of the invention; and
Fig. 3 is a detail sectional view takn along line 3-3 of Fig. 2.
Referring to Fig. 10f the drawing, 1 designates the usual gear-shift lever, by means of which thetransmission gear of the automobile may be shifted or changed as well known. The usual grounded storage battery is shownat 2. The
via conductor 3 to the ignition switch 4, which,
Conductor 7 connects device 6 to the usual timer or interrupter 8, which, in turn, is connected via conductor 9 to the induction coil 10. The secondary of this coil is connected in the usual fashion,
via conductor 11, the distributor 12 which serves to distribute the high tension current to spark plugs 13 (only one shown), as well understood.-
The ignition circuit comprises then the battery 2, conductor 3, ignition switch 4, conductor 5, device 6, conductor '7, timer 8, conductor 9, coil 10, conductor ll, distributor 12, and spark plugs 13.
is provided a unitary device designated generally by reference character 6. Referring to Figs. 2 and 3, this device comprises a casing or housing 14 within which are disposed stationary contact bars 15 and 16. The contact bar 16 comprises two aligned portions 1'7 and 18 connected by an integral side portion 19 (see Fig. 8) A third stationary contact bar or segment 20. is disposed between the aligned portions 17 and 18 and has aterminal portion 21 extending upward through a partition 22 of the housing and anchored thereto at 23. A reciprocally movable block 24 is carried at the end of rod 25. Block 24 carries opposed electrically conductive brushes 26 and 2'7, which are preferably resiliently mounted and urged outward by means of an interposed spring 28. It is essential that the brushes be electrically. connected to each other and spring 28 may take the form of ametallic coiled spring connecting the brushes both mechanically and electrically.
Blo'ck24 maybe formed of insulating material. During reciprocating movement of the block, the brushes. engage the opposed stationary contact bars, as illustrated. It will be apparent that when the block is positioned away from the center of the device, the brushes will engage contact bars 15 and 16 to complete the ignition circuit therebetween. When, however, the block is centrally disposed, the brushes will engage contact bars 15 and 20.
There is also provided a time delay switch 29, which may take the form of a thermostatic switch as illustrated. This switch comprises a bimetallic arm 30 rigidly fastened to partition 22 at one end, as at 31,.and carrying a contact 32 at its other end. The device also comprises a stationary contact 33 which is attached to terminal 21 and is normally in engagement with contact 32. An energizing winding or heating coil 34 surrounds arm 30 and is connected at one end ,to contact arm 16 and at its other end to contact 32. It will be apparent that .the parts of device 6 form a unitary assembly whichmay be readily mounted on an existing automobile.
It will now be seen that when block 24 is centrally disposed so that the brushes engage contact bars 15 and 20, the heating coil 34 of the thermostatic switch will be included directly in the ignition circuit. After a predetermined short interval during which the ignition current flows through coil 34, the bimetallic arm 30 will be flexed due to its heat-responsive characteristic and the thermostatic switch will be opened at r contacts 32 and 33, thereby opening the ignition In accordance with the present invention, there circuit and stopping the engine. The thermostatic'switch may, of course, be designed to give any desired period of operation. When block 24 is disposed away from the center of device 6, however, so that the brushes engage contact bars circuit at other times.
35 to the gear-shift lever 1.
2 15 and'16, the heating coil of the thermostatic switch will be excluded entirely from the ignition circuit, as will be apparent. It will be noted that the arrangement of the contacts is such that the ignition circuit is not broken during movement of the upper brush. This not only avoids momentary interruption of the circuit but also avoids arcing and its destructive tendencies. As clearly shown in Fig. 3, the housing is formed to provide guide portions for the reciprocating block and rod.
Rod 25 is connected by means of a flexible cable If desired, one of more guide supports 36 and 3'! may be provided for the rod and cable. Since the directions of movement of the gear-shift lever during actuation thereof from the neutral position shown are as indicated by the arrows in Fig. 1, it will be obvious that whenever the gears are placed in meshed condition by movement of the gear-shift lever, the position of the movable block of device 6 will be such as to exclude the time delay-switch from the ignition circuit. When, however, the gear-shift lever is in neutral position as illustrated, the movable block of switch 6 will be centrally disposed and the time delay switch will function in the manner above described to open the ignition circuit after a short interval.
Housing 14 may be formed of several insulating parts, as shown, to facilitate assembling of the device and access to the parts thereof. If desired a supporting bracket such as shown at 38 may be used to mount the device in desired position.
It is important to note that the device of the invention, is very simple, involving only a few simple parts, and that it takes the form of a unitary structure that may be readily used in an existing automobile. It is also to be noted that the device requires no circuit other than the usual ignition circuit and it utilizes the ignition current itself for actuation of the thermostatic switch. These advantages, as well as others, which will be apparent to persons skilled in the art, render the device a marked improvement over prior devices intended for the same purpose.
Although the invention has been illustrated and described herein with reference to aspeciflc diagrammatic illustration, it will be understood that various changes and modifications may be resorted to without departing from the spirit and scope of the invention.
