ANDREW' MOLNAR, JR., 0F JESSUP, PENNSYLVANIA.
SPARK-PLUG ATTACHMENT.
Application mea November 1o, 1921.
To all whom it may concern.'
Be it known that I, ANDREW MOLNAR, Jr., citizen of the United States, residing at Jessup, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Spark-Plug Attachments, of which the following is a specification.
This invention relates generally to the ignition means for internal combustion engines, having more particular reference to a device for intensifying the spark and en abling the operation or non-operation of each spark plug to be readily observed.
The invention has for an object to provide a simple and inexpensive device for the above purpose, capable of ready application to any type of engine already in use.
For further conprehension of the invention, and of the objects and advantages thereof, reference will be had to thel following description and accompanying drawings, and to the appended claim in which the various novel features of the invention are more particularly set forth.
Fig. 1 of the drawings is a fragmentary side view of an internal combustion engine, indicating in dotted lines the device mounted on the side thereof.
Fig. 2 is a face view of my improved device.
Fig. 3 is a transverse section on the line 3 3 of Fig. 2.
Fig. l is a fragmentary face view of the supporting bar.
As here embodied my improved device comprises a flat bar 10 of insulating material having at opposite ends the angular projected legs 12 formed with apertured feet 13, the apertures 14 in the feet 13 being adapted to receive suit-able screws or bolts for securing the device in position.
Formed in the upper, or outer, face of the bar 10 is a series of longitudinally spaced recesses such as 16 of circular shape and having communicating with opposite sides thereof the -Haring recesses 17. There are an equal number of these recesses 16 to the cylinders of the engine, or in other words these recesses correspond in number to the spark plugs of the engine.
Within the recesses 17 are set the pairs of opposed metal fingers 19 which are arranged transversely to the bar lO'and have pointed Serial No. 514,128.
ends projecting into the recesses 16 from opposite sides thereof, the adjacent ends of each pair of these fingers 19 being spaced apart a short distance as shown to provide an air gap.
Extending along the face of the bar 10 is a strip of insulating material 2O which extends over the recesses 16 and is secured at opposite ends to the bar 10 by suitable means such as the screws 21. This strip 2O has a series of apertures 22 formed therein and registering with the recesses 16 so as to leave the points of the fingers 19 exposed to view. These apertures 22 are enlarged at their inner ends to form shallow recesses in which are seated mica disks 23 which cover the points of the fingers 19.
The fingers 19 have threaded through their larger ends the screws 24 whose heads serve to bind to the fingers the wires 25 which form part of the spark plug circuit, the pairs of fingers being in series with th respective spark plugs.
In use the device may be mounted in any convenient place, being indicated in Fig. 1 on the side of an engine 30, having the usual spark plugs 31. Vith this device the action of the spark in each cylinder may be readily observed, while an efiicient action of such spark is ensured.
Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States is as follows:
A device of the class described, com` prising a flat bar of insulating material having angularly projected legs at opposite ends, one face of said bar having a series of recesses spaced therealong centrally between the sides thereof, and having flaring side recesses communicating with opposite sides of the central recesses, pointed fingers located in said side recesses and extending transversely of the bar with their pointed ends projected into the said central recesses, a strip of insulating material secured to the said bar and having apertures therein registering with the said central recesses, mica disks closing the said apertures, and binding screws threaded into the large ends of said pointed screws.
In testimony whereof I have aiiiXed my signature.
