CARL F. HIGH, OF MADISON, WISCONSIN.

EXHAUST-MOTOR.

Specification of Letters'Patent.

Application filed June 26, 1912.

Patented Dec. 24;, 1912. Serial No. 706.029.

To all 'whom 'it mag/ concern Be it known that I, CAuL F. ilion, a citizen of the United States7 residingY at Madison, in the count)y of Dane and State of lVisconsin, have invented certain new and useful Improvements in llxhaust-"Uotors, of which the following is a specification.

My invention relates to an improvement in exhaust motors and the object is to sulI stitute a motor for the fly wheel of an eu-l gine and to use the exhaust gases from the engine cylinders for operatliner the motor. iVhiie the motor performs all of the funetions of a fly wheel. its object is to assist' in carrying` the cranks over the dead center and this is accomplished by the impulse imparted to the 1notor-lrv the exhaust earl. In this manner the danger of tripping.;r the engine is overcome because the motor will receive the exhaust from the cylinder and the pressure of the gras will be sutlicieut` to carry the cranks over against compresa-ion as the high pressure exhaust, due to hie'h mean effective pressure, is increasing the turning' power of the motor and giving' power or aid in the turning' of the pistons against the co-n'ipression and therefore the more overload' that is placed upon the c vlinders, the higher the exhaust pressure and velocity and, these actingv upon the rotor. which is at a low peripheral speed. the pull is increased. l

The invention consists in certain novel features of construction and combinations of parts which will be hereinafter more fully described. illustrated and claimed.

In the accompanying d-rawines-Figure l is a VView in elevation and partly in see'- tion showing the manner of connecting' the invention to an engine and its relation thereto; Fig. 0 is a View .in sido elevation of a casing with the cover or one end plate remrn'ed; Fig. :i is a vertical sectional View of the easing; Fig'. Il is a view in side elevation of the rotor; Fig. 5 is a vertical seetional 'View ot' the rotor; Fig. 6 is a sectional view taken at an angle of 90 degrees 'from the section shown in Fig. 3. Fig. 7 is a detail view of the crank shaft extension upon which the motor is mounted.

A represents the crank ease ot' a gas engine, and l is the crank shafty to which cranks 2 are connected.

il represents the cylinders to which an exhaust pipe 3 is connected.

C represents the motor casing, and mount-l ed in the casing a rotor D. The rotor lf is mounted on au extension of the crank IshaftI 1 and is fastened to the shaft by a spline 4t.

Surrounding the .shaft 1 where it passes through the easing' is an air packing 5 for preventing' the las leal-tine'. The shal't at this point' is provided with a left handed thread 6, which. due to its rotation. causes the gas to he fed back into the chamber or casing' when any gas due to expansion should enter the threads.

The rotor D is provided on its outer surface with pockets T. These pockets are preferablvY arranged in series of three, there beine' first :1 large pocket. the next one beingT smaller and the last smaller than the .seeond. and the periphery of the rotor is made up in the formation of these pockets which receive the exhaust from cylinders of the gas engine through an outlet opening S in the easinglr C.

Formed between the hul) of the rotor and the periphery thereof are vanes 9 and conneet ed to the rear edges of thc vanes are bla-.les 1t), l0. An annular flange 11 prevents the ras from passing from the pockets T into or against the blades l0. The blades l() are preferably curved and extend to the periphery ot' the rotor. Connected t0 the blades along: the rear side of the rotor is a disk 19. the disk bein;r secnrei)Y fastened to the blades so that it is carried with the blades during their rotation and forms a means whereby the gas is caused to act upon the blades .for Causing the rotor to rotate.

The casing' (l is provided with an exhaust discharge race t3 which extends and is formed. in one end of the casing from the center and around the hub of the rotor to the outer Vall thereof. The raee is in the form of a conduit formed in the wall or end of the easinglr and becomes larger as it runs inward from the peripher)r of the casiner toward the center and around the hub. The rotor receiving the exhaust gases from the gas engine through the opening S into the pockets 7 of the rotor said gases are discharged from the pockets 'of the rotor into the conduitor racc and thence pass through the rotor between the vanes 9 Where the gas will again actV upon these vanes and cause or produce a rotary action and the gas will pass between these vanes und against the blades 10, traveling toward the periphery of the blades and imparting `a propelling action which assists in causing the rotor to rotate. The vgas is discharged from these blades into the conduit or chani 4. the gas to be discharged against a `fan (not shown), the fan being the type used on motors for cooling purposes. This opening can be closed if the fan is not used or it is not desired to operate itby means of the opening.

With an apparatus of thischaracter the exhaust gases from an engine can be conducted to the casing of the apparatus where the gases will enter the buckets or pockets 7 of the rotor and the gas may cause the rotor to be rotated and the gas escapes fromthe pockets through the conduit which leads to the center of' the casing where the gas will pass through thehub of the rotor acting upon vanes and blades carried by the rotor whereby the gas will again act upon the rotor for causing it to rotate, and each limpulse stroke of a cylinder of the gas engine is followed by an impulse on the rotor by the exhausted gas acting upon it. After the gas has done its work on the rotor, it is carried 'zhrough the conduit vwhere it is exhausted lfrom the bucket Where it gains velocity by virtue of its expansion. yThis velocity gives impulse to the vanes 9 which are set at an angle to the rotor hub and after the gas has passed over the vanes it enters at 'the'base of the receding diverging blades 'Where the remaining expansion drives the gas outward and the reaction assists in turning the rotor, and as there is no external pressure on the back or open side.v the entire pressure is for ward and this helps in turning the rotor. Thus the movement gained h v theiirst impulse and all subsequent work done. on the rotor due to expansion. creates power which can be added directly to the power ot the cylinders. Furthermore, with this appara- "tus therewill be no exhaust detonation as the-gas is expanded .during its entire course through the motor. lt is broken up by thc rotor and blended into a constant pressure in the exhaust receiver'. The contact of the gas with the motor easingr allows the casing to radiate oft' a certain amount ot the heat,

thus reducing the volume and pressure.

ln the inner wall of the casing and adjacent to the inlet opening 8 are a plurality ot' pockets 17, the purpose of which is to change the direction of the gases or vapors entering the casing and cause them to be directed toward the pockets 7 of the rotor.

Having thus described my invention, what I claimas new and desire to secure by Letters Patent is-- 1.111 an exhaust motor, the combination with a casing having an exhaust inlet, of a rotor rotatably mounted in the casing having pockets formed in the periphery thereof adapted to receive the exhaust gases as they are delivered to the casing Yfor imparting a rotary movement'to the rotor, blades connected to the rotor, a conduit in which the exhaust gases are delivered after theyhave acted upon the rotor, and a passage formed in the rotor whereby the gases pass from the conduit to the rotor and against the blades for imparting additional power to the rotor.
