ERNEST W. KUMMER, OF EDGEWATR, COLORADO, ASSGNOR GIF ONEHALF TO GEORGE C. KEEUH, F DENVER, COLORADO.

' GASQLINE-VAPORIZNG GLAND.

To all whom t may concern.'

13e it known that I, ERNEST W. Kuiirrnn,

a citizen of the United States, residing at Edgewater, in the county of Jefferson and l tirate, of Colorado, have invented certain new and useful Improvements in Gasoline- Vaporizing Glands, of which the following is a specification.

'lhis invention relates to means for heating the incoming gases of an internal combustion engine and has for its principal object the provision of a device of this char acter which will be economical to manufacture, can be quickly and easily installed without changing the present construction and which will employ the exhaust gases as a heating medium.

Other objects and advantages reside in the detailed construction of the invention, which result in simplicity, economy and elficiency, and which will become more apparent from the following description.

lin the following detailed description of the invention, reference is had to the accompanying drawing whiclrforms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.

,in the drawing:

Fig. 1 is a Yhorizontal cross section lool ing down through the cylinder block of an internal combustion engine, on the line of the inletI and exhaust valve ports, showingl the invention in operative. position.

Fig. 2 is a side elevation of the complete invention.

Fig. 3 is a longitudinal cross section through the invention, taken on the line a-e, Fig. 2.

In Fig. 1 the cylinder block of an engine is shown at 10, in which, the various parts are designated as follows: intake ports 11, exhaust ports 12, cylinders 13 (designated d in order (1), (2), (3), and (4)), intake manifold 11, exhaust manifold 15, manifold clamps 16, manifold clamp bolts 17, and valve push rods 18.

The invention comprises three uniformly spaced rings 19, 20, and 21, 19 and 21 being end rings and'20 being the middle ring. llings 11S), 20, and 2l are each provided with a peripheral raised shoulder 22 at their middles. The spz'iciug of the rings corresponds to the spacing of the intake and exhaust ports 11 and 12 of the engine. Y Rings 19, 20 and 21 are held in spaced relation by two tubes 23, which pass coinpletely through the ring 2O and terminate in the interior of each of the rings 19 and 2l, as shown at 24 and 25A respectively, in opposite facing bends. The tubes 23 pass through the raised shoulders 22 of the rings which are pressed to tight joint thereon. ln the ring 20 the tubes 23 are bent apart, as shown at 26, in order to increase the amount of tube surface within the ring.

1n applying the invention to an engine, the .intake and exhaust manifolds 1d and l5 areA removed, the manifold gaskets and glands are removed and replaced by the invention as shown in Fig. 1. The projecting edges of the rings 19, 2() and 21 lit into the port holes l1 and 120i the cylinder block 10, and into the openings of the intake and exhaust manifolds 1411 and 15, replacing the removed glands. The shoulders 22 act to replace the removed gaskets between the manifolds and the cylinder block 10.

Two of the devices are required for a four cylinder engine and are so placed that the tube terminalsV 25 turninward the exhaust ports 12 of the first and fourth cylinders. The terminals 24 will then turn outward from the exhaust ports 12 of the second and third cylinders and the rings 20 will register with the two intake ports 11 of the engine. The manifolds are4 replaced and clamped against the invention by the usual clamps 16 and clamp bolts 17.

The spacing between the tubes 23 is such that they will pass above and below the clamp bolts 17, which occupy the broken line positions indicated at 17 in Fig 2.

rlhe action ofthe device is as follows: The cylinders fire in the order of 1, 2, 4;, 3. A portion of t-he hot gases from the exhaust of cylinder 1 is caught by the extremities 25 of the tubes 23 and is forced into the tubes by the pressure of the exhaust. The exhaust of cylinder No. 2 follows closely upon that of cylinder No. 1 and creates a suction at the outward turned extremities 21 of the tubes 23, which assists in rapidly drawing the hot gases from No. 1 exhaust through the tubes.

rthis action is repeated in the other derice on cylinders 3 and il, where the exhaust of cylinder 3 follows closely upon that of cylinder 4f and assists in drawing the hot gases from cylinder t through the tubes.

This intermittent, yet rapid, succession of hot gases through the tubes 23, causes them to become highly heated and present a heated surface to the incoming gases from the intake manifold to assist in atomizing and gasifying the gasoline and air mixture therein, thereby increasing the combustibility of the gases and causing a cleaner and more rapid burning.

It will be noted that the gases are preheated at the very point they enter the combustion chan'iber, not at the carburetor or in the manifold as in other devices of this type. This prevents any subsequent condensation of the suspended liquid on its passage to the combustion chamber.

lVhile a spe'cilic form of the improvement has been described and illustrated herein, it is desired understood that the same may be varied, within the scope of the appended claims without departing from the spirit of the invention.

Having thus described the invention, what is claimed and desired secured by Letters Patent is zl. A hydro-carbon vaporizing device for internal combustion engines comprising the combination of a series of glands adapted to be placed between the manifolds and the cylinders of said engines, and tubes interconnecting and holding said glands in spaced relation, said tubes communicating between the exterior glands of said series and passing completely through the interior glands thereof.

i 2. A hydro-carbon vaporizing device for internal combustion engines comprising a series of glands adapted to be placed between the manifolds and the cylinders of said engines, and tubes interconnecting said glands, said tubes terminating in the eXterior glands of said series and passing completely through the interior glands thereof, the terminating` extremities of said tubes being turned toward said cylinders in one of the exterior glands and away from said cylinders in the other of said exterior glands.

3. rlhe combination with an internal combustion engine, of a series of glands connecting the manifolds with the cylinder ports of said engine and tribes interconnecting said glands, said tubes terminating in and cornmunicating between the glands at the exhaust ports and passing through the glands at the inta-ke ports.

4. The combination with an internal combustion engine having four cylinders, of a series of glands connecting the manifolds with the ports of said cylinders and tubes interconnecting said glands, said tubes terminating in the glands at the exhaust ports of the first and fourth cylinders of said engine in inward turned extremities, in the glands at the exhaust ports of the second and third cylinders of said engine in outward turned` extremities and passing ,completely through the glands at the intake ports so that the gases will be forced into said tubes by the exhaust of the first and fourth cylinders and willv be drawn through said tubes and thus across the intake ports by the exhaust of the second and third cylinders.

In testimony whereof, I affix my signature.

ERNEST lV. KUMMER.
