SPECIFICATION forming part of Letters Patent N01 773,713, dated November 1, 1904.

' Application filed June 8,1904. Serial No. 211,597- (No model.)

To all whmn it puny concern:

Be it known that I, FRANCIS J. Cons, of Schenectady, in the county of Schenectady and State of New York, have invented a cer- 5 tain new and useful Improvement in Locomotive-Engines, of which improvement the following is a specification.

The object of my invention is primarily to provide a simple, effective, and inexpensive IO radial truck which shall be specially and desirably applicable for supporting an overhung fire-box of the present standard wide type in locomotive-engines having a comparatively long wheel-base, as those of the Pacific or 4-6-2 type.

A further object of my invention is to provide means whereby the side frames of the engine may be firmly connected at their rear ends, the fire-box supported with the capacity of movement to relieve strains resultant on expansion, and the truck and its accessories properly supported, controlled, and connected with the main frame.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a view in elevation of the rear portion of a locomotive-engine, illustrating an application of my invention; Fig. 2, a plan or top view with the boiler and fire-box removed; Fig. 3, a rear view partly in section; Fig. 4, a plan View of a truck-spring seat; Fig. 5, a side view of the same and of the bearing-plate for the top of the journal-box; Fig. 6, a bottom view of the bearing-plate; Fig. 7, a plan view of the rollers which support the spring-seat; Fig. 8, a plan viewof the truck detached; Fig. 9, a side view of the same; Fig. 10, a side View, on an enlarged scale, of a truck journalbox;

My invention is herein illustrated as applied in a locomotive-engine having a plurality of driving-wheels 1, only the rear pair of which is shown, and having its boiler 4 provided with a wide fire-box 5, which is overhung or set behind the rear driving-wheels. The driving-wheels are fixed upon axles 1 the journals of which rotate in boxes 1, fitted in pedestals in the main frame members 8, and the overhanging weight of the fire-box is carried upon a radial truck, the construction of which will now be described.

The frame of the truck, which is of the two-wheeled radial type, is substantially tri-,

angular in plan and is made up of two forwardly and inwardly inclined radius-arms 65, a V-shaped connecting-plate 66, which is secured to and connects together the forward ends of the arms 65 and is provided with a center-pin socket 67, a U-shaped rear member 68, and two journal-boxcastings 69, which form parts of the sides of the frame, said castings' having lateral arms 70, which are connected to the radius-arms65 and to the rear member 68, respectively.

The portions of the main engine-frame members 8 in which the journal-boxes 1 of the axles l of the driving-wheels are fitted is of the usual bar type, and the portions 8 of said main frame members which extend rearwardly from the pedestals of the rear driving-axle and below the fire-box are made separate from the forward portions and are deeper and narrower than the latter, to which they are secured removably by'transverse bolts adjacent to the rear pedestals. The rear sections 8 of the main frames are connected and braced transversely by an expansion cross-tie 71, which is interposed between them below the front of the fire-box and which serves the further purpose of an expansion-brace for supporting the forward end of the fire-box and a support for the center pin or pivot 72 of the radial truck. Bearings or sockets 71 are formed in the lower portion of the expansion cross-tie, through which and through the socket .67 of the truck-frame-connecting plate 66 the centerpin 72 passes and is held in position by a key 72, the truck swiveling upon the axial line of the pin 72.

The expansion cross-tie 71 is a vertical plate strengthened by horizontal ribs or flanges and The lateral movements of the truck are versed inclines 80". The tops of thejournalcontrolled and limited and the truck normally box castings 69 carry bearing-plates 81, havmaintainedwith its longitudinal central plane ing cylindrical projections or bosses 81 on 60 in coincidence with that of the locomotive their lower faces, which fit in corresponding 12 5 by a transverse centering-spring 75, which is recesses in the journal-box castings and which fitted in a box or case 76, secured centrally permit them to be adjusted to any desired to the rear member 68 of the truck-frame. l angle with the truck-frame in accordance with The ends of the spring 75 abut on t'ollowl the swing or degree of lateral movement f0 65 ers 77, which in turn abut against the ends l the truck. The tops of thebearing-plates are 3 lipped at their ends and slightly raised centrally to form a bed or track for a pair of cylindrical rollers 82, connected at their ends by links 82, which rollers are interposed between the bearing-plates 81 and the inclined lower faces of the spring-seats 80. In the lateral movements of the truck in passing curves the rollers 82 move with minimum friction under the inclines and transfer the weight borne by the springs to the journal-box castings, while allowing the movement of the latter relatively to the springs and main frame without displacement of or abnormal strain on the springs, the relation of the rollers to the inclines acting in unison with the centering-spring to return the truckframe to central position in passing from a curve to a tangent of the road. If it be desired to provide merely the capacity of lateral movement of the journal-boxes with the truck-frame independently of the springs, this may be efiected by permitting the springseats to rest directly upon the tops of the journal-box castings without the interposition of the rollers; but the construction described and shown is deemed preferable by me in view of its greater advantages.

The truck-springs 42 are guided and controlled so as to be prevented from moving otherwise than vertically by spring-guides, which are fixed to the supplemental frame members 8 each of which guides is of the following construction: An outer guide-plate 83, having a central upwardly-extending arm and two lateral downwardly-extending arms set sufficiently far apart to clear the journalbox casting, has its upper arm connected, by bolts 83 :passing through thimbles or distance-pieces 83, with an inner guide-plate 84:, which abuts on and is connected by bolts 84: to the supplemental frame member 8 in line centrally with the outer guide-plate. Vertical guide-flanges 83 and 84S are formed on the guide- plates 83 and 84, respectively, said flanges being spaced at such distance apart on each plate as to permit the springband 42 to fit easily between them. The upper arm of the outer guide-plate is connected, as above described, to the inner guideplate 84, and the lower arms of the outer guide-plate are connected, by bolts 83 passing through thimbles 83 to arms or lugs 85, which are bolted to the supplemental frame members. It will be seen that by a guide device substantially as above described the spring is permitted to move freely in a vertical plane, as required in operation, but is prevented from being moved in any other direction under the influence of the swiveling movements of the truck.

The truck herein set forth, while more particularly designed for application as a trailing truck in locomotive-engines having an overhung wide fire-box, is not limited to such application, as it may without variation of essential structural or operative principle be used as a leading truck. It will also be obvious that other features of my invention as herein set forth may be applied in connection with supporting-wheels which operate in trucks of other constructions or which have their journals fitted in bearings in a rigid frame.
