UNITED STATES JOHN THOMAS EVANS, JIrL,

OF BROOKLYN. NEW YQRK.

INST-ANTAN EOUS STARTER.

Application filed January 16. am.

To all ec/zom it may concern:

Be it known that I JOHN THOMAS EVANS, J r., a citizen of the United States, residing at 220 88th Street, Brooklym in the county of Kings and State of New York have invented a new and useful Instantaneous Starter, of which the. following is a specification.

My invention relates to a new device for rapidly vaporizing cold gasoline as con tained in carbureters when the motor is in a condition commonly termed cold.

This invention is constructed with the object of eliminating the usual difficulty of starting gasoline motors, particularly in cold weather. It is also made with the object of reducing carbon deposits in the motor to an appreciable extent. and to absolutely prevent dilution of the crank case oil which dilution is brought about by introducii'ig raw gasoline into the cylinders by means of the choke rod the use of which is at present positively necessary to accomplish a reasonably quick and sure start. A further object of this invention is to provide a simple yet efiicient device for the purpose in View, which will be reasonably low in the cost of manufacture, and which can be easily adapted to installation on any of the present makes of American motor cars. The device herein described and illustrated is intended to fit a model 490 Chevrolet touring car, but can by changes (when necesary) later described be made to fit other motor cars.

With the above and other objects in View the inVGhtlOIi will now be described with reference to the accompanying drawing which illustrates the preferred embodiment of the same.

In the drawing: 7

Fig. 1 is a perspective view of the device with parts shown in dotted lines and parts omitted for the sake of clearness;

Fig. 2 is a top plan View of the device showing parts not shown by Fig. 1 and omitting other parts to avoid confusion;

Fig. 3 is a side View partly in section and elev'ationot the valve and ignition controlling device;

Fig. l is a sectional detail view.

Referring to Figure 1, the object drawn represents in the main a cylinder otapproxinrately five and one'halt inches in diameter enclosed' at both'ends with metallic plates and having steel tube of one and one half inchesfldiameter inserted in the center, the

ends of which-protrude from each end-plate Serial No. 613,075.

for a distance of one half inch. Number 17 indicates the cylinder itselit'. Numbers 15 and 16 the end plates which are drawn tightl'y against the ends of the cylinder by means of two bolts marked 18. Directly in the center of the cylinder and the two end plates is inserted a steel tube of one and one half inches diameter and approximately one thirty-second of an inch thick. is indicated by number 2. Attached to both ends of this tube are two elbows marked 22 and 23. Attached to the end of these elbows are two short pieces of tube (one quarter of an inch protruding from each elbow) marked 4i and each pierced with a hole marked 7 and 8. All leading makes of motor cars are equipped with a stove which is a metallic shell encircling the exhaust pipe. The air used in carburation is drawn thru this stove and conveyed to the carbureter by means of flexible steel tubing. After the motor has been in operation for at least five minutes, the exhaust pipe becomes very hot, and as a consequence the air drawn in thru the strw'e becomes thoroughly heated. This hot air when it reaches the'carbureter and comes in contact wtih the raw gasoline contained therein, causes such gasoline to vaporize or become volatile instantly, thus aiding materially in forming the correct gaseous substance which produces perfect com'b'ustion within the motor. t'iowever, when the motor is left standing ir operative for any length of time, it cools off, and when weattempt to operate it again, we have no hot exhaust pipe to heat the air sucked in around the stove? As a consequence we resort to the choke rod which by its action excludes a great deal of the air from the carbureter, and naturally only raw drops of gasoline are drawn into the firing chamber. These do not explode readily it at all and are instrumental in forming most of the carbon found in all gasoline motors.

' It also seeps down past the piston rings and dilutes the lubricating oil in the crankcase In time some of this raw gasoline will become ignited and the motor will start functiorling, not however as it should. There will be considerable misfiring and uneven operation until the exhaust pipe hec'oines hot enough to warm the air being drawn in thru the stove. This invention is intended to supply the hot air when the motor is cooled-oft or in a condition com monly termed cold.

This tube able fuel.

Referring back to the description of the device itself the flexible steel tubing leading from the stove is to fit snugly over parts marked 4 and 5 which will bring hole 9 on flexible steel tubing in line with holes 7 and 8, when bolt 6 may then be inserted to accomplish a union of the parts in question.

lVhile passing thru tube marked 2 (Fig. 1) the air is thoroughly heated to approximately 180 degrees Fahrenheit in ten to fifteen seconds by means of nine burners each marked 1O which utilize for any suit- This fuel is conveyed to the burners thru three pipes each marked 11. These pipes are connected at the upper end as indicated in Figure 2 by means of elbows marked 12 and Ts marked 13. lVith further reference to Figure 2, object marked 14 tips 10 are simply small steel tubes made of nonoxidizing steel and threaded at one end for connecting them to feed pipes 11. Attached to outer cylinder 17 are pipes of one and one-quarter inches diameter placed as indicated by numerals 20 and 21, which are used to convey air to the inside of said cylinder. Flexible steel tubing-of a sufficient size is connected to the ends of said pipe in the same. manner as described above with reference to parts marked 4 and 5. These sections of flexible tubing connected to pipes 20 and 21 are of a length sufficient to reach for at least eight feet to some underneath outside part of the car. This is a precautionary measure to insure absolute safety when the burners are functioning. The oxygen so necessary to fire will be drawn from a source where there will be no danger of contamination with fumes of gasoline-or other inflammable substances.

With further reference to Figure 1, number 19 indicates a threaded hole cut in cylinder 17 which will be of a size sufficient to accommodate a standard half inch spark plug which shall be instrumental in igniting the gas issuing from the burner tips.

I will now refer to Figure 3 which represents the controller of the device previously described. Number 24 indicates a metallic plate of approximately three inches width and four inches depth. Each corner of said plate shall be cut with a countersunk hole to accommodate a bolt such as marked by numbers 25 and 26 the purpose of, which bolts is to attach said plate to the instrument board of an automobile. It will be necessary to cut a hole in the instrument board approximately two and three quarters by three and three-quarter inches in size so as to accommodate the parts attached to the back of plate 24. Numeral 27 refers to a nickel plated round metallic knob attached to rod 28 for the purpose of being easily grasped by a human hand. Rod 28 is to be approximately three inches in length and will project thru a hole of sufficient diameter which shall be cut in the center of plate 24. A pin shall be inserted thru rod 28 as indicatedby number 29. Directly behind pin 29 shall be a metal washer number 32 which shall slide freely on rod 28. This washer will be of a diameter sufiicient to insure its coming in contact with points marked 30 and 31 when knob 27 is grasped and pulled away from plate 24. Directly behind above described washer shall be a coil spring as indicated by number 38 which shall be retained on rod 28 by washer 33 and pin34. The purpose of this spring is to hold in absolute contact with points 30 and 31 larger washer number 32 when rod 28 is pulled out thru plate 24. This will make the electrical contact to produce a spark at the points of the spark plug inside cylinder 17 (Fig. v1) said spark plug being screwed into hole 19 (Fig. 1). )Vhen rod 28 is pulled out thru plate 24 it will not only cause the electrical contact above described, but will also open valve 14 (Fig. 2) when a cable such as indicated by 14 (Fig 2) is suitably connected to the valve handle as illustrated and con nected to hole 3.5 on rod 28 (Fig. 3). This arrangement of parts will automatically perform two operations at once. It will turn on the gas or fuel and at the same time produce a spark to ignite" the fuel thus producing the results desired. A further point of value is the fact that the device only functions so long as the individual or operator knowingly keeps rod 28' withdrawn from its socket. hold is released, spring 14 (Fig. 2) pulls rod 28 (Fig. 3) back into its socket at the same time pulling valve 14 (Fig. 2) to an off position and drawing washer 32 (Fig. 3) away from contact points 30 and 31, thus the device ceases to function.- r

Referring back to Figure 3, numbers: 40 and 41 indicate two circular pieces of insulating material such as hard rubber or compressed fibre. Ahole shall be countersunk in the center of one end as illustrated to accommodate a bolt of sufficient size, said bolts indicated by numbers 30 and 31. Under the nut of each of these bolts can be secured the wires used. in making the electrical connections to produce the spark at the spark plug points. These pieces of insulating material referred to above are attached to plate 24 by As soon as the operators smallbolts marked 42 and 43 which are set spring the purpose of which is to keep knob 27 pressed firmly against plate 24 to prevent rod 28 from rattling in its socket.

Figure 4 is an enlarged view illustrating the manner in which pipes 11 (Fig. 1) are passed thru end-plate 15 (Fig. 1). A hole of a diameter slightly larger than pipe 11' (Fig. 4) is cut in plate 15. The upper ends of pipe 11 are threaded to accommodate locknuts 51 and 52. To firmly aflix pipes 11 to plate 15 simply place same thru hole indi cated by number 53 and tighten lock-nuts 51 and 52.

lVhile I have shown and described the preferred specific embodiment of the invention, it will be understood, in view of my disclosure, that the invention is capable of other embodiments and that certain changes in the construction and arrangement of parts to accommodate the device to the various types of automobiles may be made without departing from the invention as defined by the appended claims.
