Specification of Letters Patent.

Patented Dec. 14, 1920.

Application filed July 6, 1920. Serial No. 394,238.

To all whom t may concern.'

Be it known that I, GEORGE KiiAKowsiiY, a citizen of the United States of America, residing at South Bend, in the county of Saint Joseph and State of Indiana, have invented certain new and useful Improvements in Locomotives, of which the following is a specification.

The primary object of the present invention is the provision of a locomotive capable of attaining great speed from a minimum expenditure of fuel, the construction being simple and possessing great strength and endurance.

A further object of the invention is the provision of a high speed locomotive pos sessing great power after the nature of a double action compound engine, enlarged divers being employed whereby the draft is equalized throughout the entire body of the locomotive.

A. still further object of the invention is the provision of a locomotive having forward and rear drivers simultaneously operable by steam power derived from a double boiler having a single steam chamber and steam dome communicating with the steam chests of the driving cylinders.

Another object of the invention is the provision of a locomotive having acentral stabilizing` truck assisting in maintaining the equillibrium of the locomotive in travel upon the track.

1t is also designed to provide with a locomotive a tender having its truck connected for resiliently supporting the rear end of the locomotive cab for absorbing vibrations and jars incident to travel.

l also provide means upon myl high speed locomotive for slidably maintaining the same upon. the track rails in case of the accidental derailment of the main drivers and whereby the locomotive will be maintained upright in a sliding position upon the track. My double boiler construction is of the firetube type having dual fire boxes within the locomotive cab it being understood that either solid oi' fluid fuel maybe employed according to the equipment of the railroad line.

`With these general objects in view the invention consists of the novel combination' and arrangement of parts hereinafter more fully described in connection with the accompanying drawings and in which like reference characters designate corresponding parts throughout the several views.

In the drawings,

Figures 1, 2, and 3 are developed substantially continuous -side elevational views of my locomotive and tender, portions being omitted and broken away,

Fig. 4. is a vertical transverse sectional view substantially centrally through the locomotive with parts removed,

Fig. 5 is a similar sectional view through,

the double boiler at one point of connection between the boilers,

Fig. 6 is an elevational view of the central portion of the frame showing the swiveled stabilizing truck,

Fig. 7 is a central longitudinal sectional view through the forward end of the locomotive,

Fig. 8 is a similar sectional view through the central portion thereof,

Fig. 9 is a similar sectional view through the rear end of the double boiler and fire box, and

Fig. 10 is a detail view illustrating one of the sliding shoes operatively positioned upon the track.

Referring more in detail to the drawings my invention broadly consists of a steam generator comprising upper and lower boilers 1() and 11 arranged parallel one above the other with superposed tire boxes 10 and 11 respectively at the rear of the boilers and an outlet 'chamber 12 for the products of combustion at the forward end of the boilers having a smoke stack 13 at the top of the chamber. Similar side frames are secured opposite the side of the boilers 10 and 11 comprising central plates 14 with rear extensions 15 out away longitudinally as at 16 and also having forward extensions 17 with similar longitudinal cutaway portions 18.

The extensions 15 terminate in downward .inclined portions 19 at the opposite sides of the cab 20 at the rear of the boilers 10 and 11 with the fire box doors 21 and 22 positioned within the cab.

The forward extensions 17 terminate as at 21 adjacent the forward end of the boiler connecting chamber 12 at the front ofthe locomotive.

The main driving cylinders 23 are oppo-v sitely positioned substantially centrally of the locomotive outwardly of the main frame plates14 and are operatively connected to steam chests 24 in the usual manner, the steam chests 24 beingsecured to the plates14 beneath the cylinders 23. The boilers 10 and 11 being of the lire-tube type, the lower boiler 14 is provided with tubes 25 and the lower portion` of the upper' boilers 10 with similar tubes 26 opening at their rear ends in the iire boxes 11 and:10 respectively for conveying the heated gases andgproducts of combustion through the said pipes tothe chamber l'12 'into which Vthe open forward ends of the tubes 25 and 26 are exhausted. lThe'tubesl26 of the upper boilers 10 are provided'rin the lower portionthereof leaving 7 a steam spacel 27 in the upper side of thetop boiler 10 communicating with a steam dome 28 positioned .substantially centrally upon thetop oftheboiler 10.

Thermain su'pportfor'the 'locomotive comprises forward'pand rear drivers 29 and 30 respectivelyhaving main driving shafts 31 and 32extending transversely through the space b'etvveentheboilers 10- and 11 ywiththe shaft '31 extending through the cutaway portions 18 o-fthe forward extensions 17 and the rear shaft B2f'throughthe eutawayportion 1`6`ofthe rear extensions 15 ofthe main frame. Main boxings 33 for the rear drive shaft`32 are connected by equalizing springs 84 and- 35 with the rear frame extensions 15, the springs-lying within the cutaway portions 16 of'such extensions with their inner ends linked to saddlemembers 36 uponthe boxes3'3.

The rear ends ofthe rear springs 84 are connected by links 37 with'the lower sides of the rear extensions 16 while the front end of 'the forward springs 85 are connected by li'nks138 'with't'he upper'sides of the rear extensions 416. In Va similar manner, the forward drive shaft 31 is journaled in'boxes 83 for supportingthe iforwardextensions 17 of 'the main side yframes by means of rear and forward springs 34 'and 85 respectively. Eachm'ain cylinder 23 is double-acting hav ing an axial piston Yrod 39 for driving front and 'rear cross heads '40 and 41 respectively sl'idab'ly-1nounted in parallel guides 42 and 43 "respectively extending` forwardly and rearwardly Ifrom the 4main cylinders 23. The cross fheadsf40 and 41 are operatively connected to the hubs 44 and 45 of the front and rear dri'vers'by means of main rods 46 pivoted between the cross'hea-ds and pins 47 eccentrically carried outwardly projecting from the hubs 44 and 45. The -steamdome 28 is connected to the steam chests 24 by pipes '48:a'tthe opposite sides of vthe locomotive, while link operating mechanism 49 of any well known 'form Vis operatively con nectednbetween the pins .47 and the valve stem '50 of thelsteam 'chest 24 outwardly of the'ends: o'ff'the steam chest and whereby the control of steam to 'the main cylinders 23 is y'boilers l0 and 11 extendino` forwardlv to the chamber 12 with an angular pipe 53 pro- ]eetingffrom the forward end of the inanifold 52 upwardly into an e]ector tube 54 through whieh'the products olf combustion from the chamber 12 pass to the stack 13 and whereby the exhaust steam through the pipe :S3-entering the tube 54 accelerates the draft ofthe lire boxeslO and 11. A eomiecting conduit 55 between the boilers l() and ll is provided between each set of driving wheels whereby the two boilers have a single steam space 27 in the upper boiler l0 with the lower boiler 11 normally lilled with water as well Ias the conduits 55 andthe upper boiler 10 to apoint such as 5G above the level of the fire tubes 26 therein. The usual form of air brake mechanism may be employed a pump 57 and brake cylinder 58 lwing herein illustrated to show a suitable position for the same upon one of the side plates ll of themain frame.

A central equalizing truck 59 is positioned beneath the lower boiler 11 having relatively small wheels'59'for traveling upon the trawl; and usual spring suspension means (51. A socket 62 carried by the central truck 55) serves as a bearing for a ball G?) upon `which rests a corresponding socket member G4 eentrally secured to a connecting plate (35 spanning thelower edges of the side plates i4. ln this manner, the central truck 5) supports part of the weight of the locomotive beingswiveled anti-frietionally mounted thei'ebeneath by the supporting bearing (32%. This arrangement stabilizes the loroniotive assisting in preventing the same from leaving the rails during excessive rates of speed and when rounding curves.

A wind-deiiector G4 of suitable form is secured forwardly'of the locomotive while a slide member or shoe. (35 at the bottom of the deliector and similar shoes GG at the front and rear of the central truck 5S) are normally positioned*slightly above the track for Slidable engagement therewith should the drive or truck wheels accidentallyv leave the rails. A similar shoe 37 carried heneath the eab 2() and it will be apparent that if the locomotive berolnes derailed. the same would slide along over the rails upon the shoes (35, 6G and G7, without turning over. rlhese shoes are of `considerable width and suitably iianged as illusi'irated in the detail view Fig. 10, in connection with a rail 68 therein illustrated in vertical transverse section. The throttle lever GS) is located within the cab20 and operates in the usual manner.

A fuel carrier or tender 70 is coupled rearwardly of the eab'2'0 mounted upon its lll() own truck 71. Means are provided for equalizing shocks and supporting a part of the weight of the cab Q0 from the tender truck 71 and consists of an angular bar 72 coupled by a pin 7 3 with the bracket 74 of the shoe 67 beneath the cab 20. The bar 72 has its rear end anti-frictionally journaled by means of spaced balls 74 centrally of the truck 7l while the -bar 72 extends through a bracket 75 depending from the rear end of the cab 20. rlllhe ball 7 6 in the bottom of the bracket 75 has the bar 72 mounted thereon while a ball 77 upon the top of the bar 7 2 has a spring 7 8 interposed between the same and an adjusting wedge 7 9 extending through the top of the bracket. The vertical vibrations of the cab 20 are absorbed by the springs 7 8 which is adjustable in tension by means of the wedge 7 9.

The complete operation of the invention will be fully understood from this detailed description thereof, the increased steam capacity of the two lire-tube boilers being apparent as well as the capacity for power possessed by the opposite double-acting main cylinders 23. The drive wheels 29 and 30 are preferably of greater diameter than the height of the boilers or cab 2O being capable of revolving by the great power of the steam plant. The locomotive is thoroughly equilibrated for maintaining the same upright on the track at great speeds of travel, the locomotive being capable of pulling great loads as well as traveling at unusually high speeds. lt will be noted that while the main cylinders 23 are carried outwardly of the side plates 14.- of the main frame, the guides 4l?) for the cross heads 40 and il are outwardly of the driving wheels 29 and 30. The locomotive possesses great safety being prevented from leaving the track by the stabilizing central truck 59 and provided with the safety sliding means consisting of the shoes 65, 66 and 67 in the event of an accidental derailment of the locomotive. The winddeflector 64:l forwardly of the locomotive decreases the air resistance during forward travel while the equalizing suspension springs 34, 35, 234i and 35 mount the boilers and their mechanism in a cushioning manner upon the main shafts 3l and 32.

,While the form of the invention herein set forth is believed preferable it will be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what l claim as new and desire to secure by Letters Patent is l, A locomotive comprising a horizontal boiler, forward and rear drive wheels upon which the boiler is mounted, a main frame carried by the boilers, a central truck beneath the frame and central boiler and socket connections between the truck and frame.
