STEAM GENERATOR Patented Oct. 18, 1932 UNITED STATES PATENT ori-'ICE ROY M. WARFIELD, OIF-CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, OF ONE- THIRD TO STANLEY STEAM MOTORS CORPORATION, A CORPORATION OF DELAWARE STEAM GENERATOR Application filed. June 24,

My invention relates to a steam generator adapted to be used for the locomotion of vehicles of every kind and description and wherever a small portable steam power plant '5 can be applied.

An object of the present invention is to provide a novel steam generator having a plurality of spaced banks of tubes so arranged and associated with one another as to provide .10 a maximum of surface area for the transfer of heat units to the circulating medium therein, as likewise to provide an assembly, the component parts of which may be readily and easily repaired or replaced.

Another object of the invention is toprovide a novel steam generator comprising spaced banks of tubes, the banksof tubes being connected to upright headers such that there vmay be unrestricted expansion and conl traction of the tubes.

A further object of the'invention is to provide a novel steam generator having a plurality of spaced banks of tubes, these banks of tubes being connected by suitable means for providing a continuous thermo-siphonic circulation of the liquid flowing therein; novel means being also providedy for allowing the liquid in the tubes to vary without affecting the thermo-siphonic circulation of the liquid.

Another object of my invention 1s to provide a steam generator having the sections thereof inclined and criss crossed so that the heating medium is completely utilized and l wherein a thermo-Siphon circulation of the water in the generator is eHected thereby preventing caking of impurities on the inside of the tubes; during said circulation the water passes through large mud drums which permits sediment to settle from where it may be blown off at intervals.

My invention will be best understood by reference to the accompanying drawings forming a part of this specification and in which,

Figure 1 is a side elevational View of a steam generator embodying my invention.

Figure 3 is a rear elevational view of that disclosed in Figure 2.

Figure 4 is a sectional view of that disclosed in Figure 1 and is taken on approximately the line .lr-4 of Figure l.

Figure 5 is a sectional view taken on the line 5 5 of Figure 2.

In the drawings and for the purpose of illustration I have shown the preferred enibodiment of my invention which consists, of a steam generator composed of a plurality of water tubes 10 arranged in sections or banks of twenty secured between

tube headers

11 and 12, the banks are held in position .by two

unions

13 and 14 at open corners which'allow expansion of said tubes without setting up eX- cessiv'e strain on any of the parts. The unions are secured to bank headers by butt welding to the point 16 as shown in Figure 2. In order to make this butt weld the stock from which the bank headers are composed is first stamped out in U dies and the portions 17 are drawn out cold for butt welding to the short tubes 18 which are connected to the tube headers by the

unions

13 and 14, as hereinbefore described, and the

bank headers

19 and 24 are i then formed into a tube and seam welded.

rlhe banks of tubes, ten in number, are crisscrossed alternately as best shown in Figure 4 in order that the heat of the fire will be more completely utilized and in order that a quicker and more etlicient generation of steam nia-y be eected. rEhe headers 19 empty into the lateral water carriers 2O which in turn empty into circulation tubes 21 which pass downwardly to the rear end of the mud drums 22 which are connected at the other end to the other mud .drums 23 by a pipe 24', as clearly shown in Figure 5.

From the rearward end of mud drums 23 water may pass upwardly into the bank headers 24, into the tube headers 12, and upwardly through the banks of tubes and back through the tube headers 11 to the thus completing a cycle.

The water or other liquid whichwmay be used in the operation of this generator isnormally carried to a position approximately half way up in the U tubes 25 between the lateral water carriers 2O and the vapor drums bank headers 19,V

26. The vapor from the generator passes into the drums 26 and from there through the Connecting tubes 27 to the

drums

28 and 29. Some of the vapor also passes through the connecting tubes 30 to the vapor drums 3l.

From the drum 28 tubes 32 connect with cause of the fact that the drums are conipara- A tively small and in' order for vapor to reach any of said drums it must pass 'to them through some of the small connecting tubes as herein described.

The vapor drums 35 are connected .by cross tubes 36 and the cross tubes 36 at the front end of the generator are welded to a downwardly extending supply tube 37 which opens into a drum 38 which is in turn connected to a similar drum 39 by vapor tubes 40 which constitute a super-heater. The drum 39 is connected to a supply tube 4l which has a suppl ot er vapor is taken for power purposes.

From one of the vapor drums 31 a tube 43 extends; said tube passes downwardly near the rear side of said generator and opens into an outlet 44 to which a steam gauge (not shown) will be attached when in operation.,

The tube 24 which connects the muddruins at the front end of the generator, is provided with valves 45 at each end thereof for permitting the sediment to be blown out ofthe l mud drums whenever desired. The tube 24 is also connected to a water supply drum 46 which has a valve 47 on the other end thereof through which a supply of water or other liquid enters the drums and finds its way to all parts of the generator as hereinbefore eX- plained. To the rear end of the mud drums 23 are secured outlet tubes 48 having valves 49 therein for permitting the sediment from the mud drums to be blown out in thatdirection, if desired.'

Adjacent both ends of the mud drums and the water supply drums are strap members 50 which are secured by clamping members 5l and bolts 53. To the ends of the rear straps 50 are secured end supporting members 52 secured to the straps 50 by bolts 54, as shown in Figure 5, similarly a supporting member 56 is secured to the strap 50 on the front end of the generator by a bolt 57. To the two supporting members at the rear of the generator, and the supporting member at the front of the generator which together comprise a three point suspension for the entire generator, a frame member 58 is secured which may be any suitable frame member, and preferably, the under casing which will be normally secured outlet 42 thereon from which steam orl of construction set forth but desire to avail myself of such changes and modifications as come within the scope of the appended claims.
