KEROSENE-VAPORIZER.

Specification of Letters Patent.

. Patented July 3, 1211 t.

Application filed April 17, 1916. Serial No. 91,713.

To all whom it may concern.

Be it known that I, JOHN VAN DEN Bos,

a citizen of the United States, residing at" Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Kerosene- Vaporizers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

My invention is a vaporizer for use in connection with the carbureter and exhaust manifold of an internal combustion engine for the purpose ofallowing kerosene and other heavy oils to be used advantageously as fuel for the engine.

The main object of the invention is to provide a device of the class specified which may be easily and inexpensively manufactured and marketed, yet which regardless of these characteristics will be highly eflicient and durable and will be applicable to the carbureter and exhaust manifold of practically any type of engine.

lVith this general object in view, the invention resides in certain novel features of construction and in'unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which constitute a part of this application and in which:

Figure 1 is a side elevation of the invention applied;

Fig. 2 is a top plan view thereof;

Fig. 3 is a central vertical longitudinal section of the device; Fig. 4 is a central vertical transverse section thereof; and

Fig. 5 1s a vertlcal longitudinal section taken in the plane indicated by the line 55 of Fig. 4.

In specifically describing the construction shown in the drawings above briefly .described, similar characters will be placed on corresponding parts throughout the several views and reference will be herein made to the numerous elements by their respective with rounded internally threaded ends 2 for the attachment of two sections 3 of an exhaust manifold, said ends being referably greater in diameter than the Wi th of the conduit 1.

A metal jacket 4 surrounds and is spaced from the conduit 1, said jacket being also rectangular in transverse section and having its ends directed inwardly and joined integrally to said conduit. The lower side 5 of the jacket 4 is increased in thickness and is provided with a flat lower surface, said surface being adapted for contact with the usual outstanding flange 6 on the discharge neck 7 of a carbureter. An inlet bore 8 is formed through the side 5 for registration with the bore of the neck 7 and at points spaced from the bore 8 screw holes 9 are formed in the aforesaid side 5 to receive screws 10 which pass through the flange 6. It may here be explained that screws or bolts such as 10 usually pass through the flange 6 to secure the intake manifold to the carbureter, and that the arrangement of the screw holes 9 is such as to allow the improved vaporizer to be secured to a number of types of carbureters without in any way altering the latter, and in fact, by making necessary changes, the device may be used in connection with any style of carbureter or mixing valve.

The fiat upper side 11 of the jacket 4 is provided with an integral upright discharge neck 12 having an-outstanding flange '13 which corresponds in size and shape with the flange 14: on the intake manifold 14, whereby said manifold may be readily se cured thereto by bolts 15. One side of the neck 12 is provided with an outwardly projecting boss 16 having therethrough a bore 17 which alines with an additional bore 18 in the opposite side of said neck, these bores being adapted to receive the shaft of a throttle valve V, and for the purpose of limiting the movement of said valve, a rib 19 extends from the boss 16 to the top 11 and projects beyond said boss, this rib being adapted to serve as a stop for cooperation with the usual stops S on the operating lever L of the valve.

The upper and lower sides 20 and 21 of the conduit 1 are rovided with spaced parallel transverse ri s 22 which extend therefrom toward the upper and lower sides 11 and 5 of the jacket 4;, said ribs terminating flush with the vertical sides 23 of the conduit.

- Other parallel transverse ribs 2 4 are formed integrally with the upper and lower sides 11 and 5 of the jacket 4:, said ribs being of approximately the same length as the ribs 22 and projecting between the latter as shown most clearly in Figs. 3 and 5, t i

to the upright sides 23 I maining opposed sides of of said ribs 24 extending across or the inlet 8 and the outlet neck 12.

Positioned between and joined integrally of the conduit 1 and the upright sides 25 of the jacket 4 is a trio of longitudinallyextending series of spaced longitudinal ribs 26, the ribs of the intermediate seriesbeing disposed in staggered reserve not only to conduct heat from the several walls of the device into the spaces between said walls, but they also provide tortuous courses for the mixture from the carbureter, thereby insuring thatallparticles thereof be reliably broken up and heated to the necessary extent. I

In addition to the advantages just enumerated, it will be obvious that the invention may be manufactured easily and inexpensively, and may thus of a great number ofautomobile owners.

' In the foregoing, I have described certain specific details for accomplishing probably the best results and in the accompanying drawings I have shown such details. Nevertheless, it is to be understood that numerous changes may be made within the scope of the invention as claimed Without sacrificing the main advantages thereo I cla1m: 1. A device for. vaporizing the volatile mixture from a carbureter, said device comprising a conduit rectangular in cross section with open, ends for the attachment of sec tions of an exhaust manifold, a rectangular jacket surrounding said conduit 'and spaced therefrom, said jacket having two of its opposed sides an inlet and an outletffor connection respectively to the outlet ofa'carbureter and to anfintake manifold, z-said sides of the jacket, having spaced transverse ribs extending toward theadjacent sides of the conduit, and said sides of the conduit having aced transverse ribs extending e. I:

other ribs, the rethe con uit having a number of longitudinal series of s aced longitudinal ribs extending-to the ad acent walls of the jacket. v

2. A device for vaporizing the volatile jacket and between the spanning be placed within reach.

mixture .from a carbureter, said device comprising a conduit rectangular in cross section with open ends for the attachment of sections of an exhaust manifold, a rectangular jacket surrounding said conduit and spaced therefrom, 'said' jacket having in two of its opposed sides an inlet and an outlet for connection respectively to the outlet of a carbureter and to an intake manifold, said sides of the jacket having spaced transverse ribs extending. toward the adjacent. sides of the conduit, and said sides of the conduit having spaced transverse ribs extending toward the jacket and'betw'een the other-ribs, certain of said ribs spanning the inlet arid the outlet, the remainingopposed sides of the conduit having a number of longitudinal.

series of spaced longitudinal ribs extending to the adjacent walls of the jacket.-

3. A device for vaporizing the volatile mixture from a carbureter, said device comprising a conduit rectangular in transverse section with rounded internally threaded ends for the attachment of sections of an eX-' haust manifold, and a rectangular jacket surrounding and spaced from said conduit, said jacket having its ends formed integrally with the conduit and having one of its sides increased in thickness and formed with a flat outer surfacefor contact with the outsaid thickened side having formed therethrough an inlet bore for registration'with said outlet of the carbureter and also havstanding flange at the outlet of a carbureter,

ing threaded openings for the reception of v screws to be passed through said flange, the opposed SldQOf the jacket having formed integrally therewith 'a hollow discharge neck equipped with an outstanding flange at its free end to facilitate the attachment of an intake manifold thereto, the aforesaid sides ofthe jacket having integral transverse ribs extending toward the adjacent ides of the conduit, certain of said ribs spafdiing the inlet bore and the outlet neck, while said sides of the conduit are equipped with, similar transverse ribs extending between the other ribs, the remaining sides of the conduit being provided with a number of longitudinal series of longitudinal ribs formed integrally therewith and with the adjacent sides of the jacket, the ribs of adjacent series being disposed in staggered relation. .I
