To all iohom it concern:
Be it known that I, CLYDE J. COLEMAN, d
, citizen oi the United States, and a resident gaseous mixtures.
of the borough of Manhattan, in the county of New York, city of New York,-'and State of New York, have invented new and useful Improvements in Rotary Impact-Engines,
.of which thefollowing' is a specification, referencebelng had to the accompanying drawings, forming part thereof.
This invention relates to improvements in rotary impact engines, wherein rotary movement is directly'produced from and by the combustion of explosive gases or gaseous mixtures, forming the motlve fluid.
The main object of myinvention is to produce rotary motion from practically continuous combustion of explosive gases or Further objects of my invention are the provision of means whereby the motive fluid employed may be permitted to expand before reaching the point of impact, the" prevision of an injector, or injectors, for introducing the motive fluid, and the provision of a blower in connection therewith.
My invention also includes certain novel features of construction and combination of parts, all of which will appear from the following description pf the engine embodying my invention illustrated in the acco'mpan ing drawings.
Figure 1 is a side view, partially in central vertical section of an engine embodying clination to radial lines.
spaces between the blades or vanes are exteriorly entirely uninclosed. Interiorlythey are uninclosed by any stationary part but are arranged opposite to a plurality of turbine blades or vanes 5 with which the rotary part 2 is provided. The annular side plates 3, 3, and the turbine vanes 4 carried thereby, and together forming the stationary part 1, are supported bysuitable brackets 6, 6,
mounted upon a bed-plate 7. The rotary 1. e drawpart is mounted upon a suitable shaft 8 journaled in bearings 9-9 also secured to bedplate 7. The rotary part carries a pluralit of in ectors, the. inner nozzles 10 of whic connect Wlth a supply of motive fluid, in this instance carried 1n through the interior of the shaft 8, made hollow for such purpose,
and the outer nozzles 11 of which communicate with the outer atmosphere or other supply of cooling medium through central openings in the side walls 12, 12, of the rotary part 2. Pipes 13 form suitable connections between the hollow shaft 8 and the, nozzles 10, and further form supports there for. Each of the injectors discharges into one of a plurality of expansion chambers 14, one for each injector, and each of these chambers connects with a number of spaces intervening between a plurality of turbine vanes or blades 5, said turbine vanes forming the outer wall of such expansion chamber.
Intermediate of the injectors and expansion chambers are arranged cooling chambers 15. Each of these cooling chambers connects with the central opening in the side walls 12, and with one or more of the intervening spaces between the turbine vanes or blades 5. The cooling chambers are 'oon-' nected together moreover around thewalls of the expansion chamber, as will be readily.
understood by reference to Fig. 1.
In operation the rotary part 2 revolves rapidly and draws in air or other vapor by the action of centrifugal force through the central openings in the side walls 12, and the air or other vapor thus drawn in, passes to the outer nozzles 11 of the injectors and to the cooling chambers 15. In order to augment this centrifugal force I connect a blower therewith, and in the drawings I have'shown the rotary part 2 as provided with fan blades 16-, these fan blades being arranged opposite both the openings in the side walls 12, and being adapted to act as a blower.
The blades 16 I herein term fanblades for the purpose of distinguishing them from the coacting turbine vanes heretofore described. structurally they may or may not difler from them as may be desired. They are herein shown as radially arra d, but ma if desired, be arranged at an mciina'tion to radiallines.
I have shown a conventional representation of a carbureter the drawings atg1-7,
ventional igniting circuit at 21 for the pur-- pose of igniting the motive fluid in first starting up the enginewhen once started u the flame will pass from one to another oi the interveningspa-ces between the turbine vanes or blades and successive igniting by an independent igniting means will be unnecessary. v
When the engine is running normally, motive fluid will be drawn from the carbureter, through the hollow shaft and through the inner nozzles of the injectors by the action of centrifugal force in the rotary part of the engine. Air or other vapors will be also drawn through the outer nozzles 11 by inductive action, augmented by the fan blades, and the mixture will be deliveredinto the chambers 14. Ignition will take place at the mouths of the inner nozzles 10. The rapid accumulation of pressure however, due to ignition, is greater than is required in the turbines, and much greater than will give the best results. It has been found that a maximum economy is obtained where the speed of a turbine is one half the velocity of the motive fluid at the point of impact. For this reason I permit the ignited motive fluid to expand'in the chambers 14 and thereby reduce both its temperatures and its velocity between the point of combustion and the point of impact. The vanes 5 direct the ignited motive fluid toward the impact vanes 4 and the result isa powerful rotary movement of the part 2 in the direc-' 'tion of the arrow in Fig. 2. The air or other vapors drawn, or forced, in through the central openings in the walls 12 act also as a cooling medium in circulating through the cooling chambers 15 and around the walls of the expansion chambers 14, and further tend, to cool the turbine vanes or impact blades by discharging therethrough and to clear the same of the residual products of combustion Inorder to avoid back-fire I provide the injectors Lwith guards of wire mesh 22 or the like, as clearly shown in ,thedrawings. It is evident that various modifications may be made in the'constructions above particularly deseribed within the. purview of my invention and} that parts of my invention may be embodied in 'otherconstructions than those shownaiid describe What I claim and desire to secure by Letters Patent is I I 1*;
